The invention relates to a method of radio communication in which the user station to transmit messages using two different code, with the first application of both codes is temporarily interrupted, and during the interruption introduces the application of the second code from both codes. In addition, the invention relates to user stations and network device for implementing the method.

In the communication system messages, for example, voice information, information, images, video information, SMS (short message service), service (MMS multimedia messaging), or other data is transmitted using electromagnetic waves between the transmitting and receiving stations. As stations may, depending on the specific implementation of the radio system, used a variety of custom station or network of stations, such as base stations. In the mobile communication system, at least part of the user stations is a mobile station. The exposure is carried out with carrier frequencies that lie in the range specified for the respective systems.

Mobile communication systems are often performed as a cellular system, for example according to the GSM standard (global system for mobile communication) or UMTS (Universal Telecom the communication system) network infrastructure, consisting of base stations, devices for monitoring and control base stations and other network devices. In addition to these globally organized (overloking) hierarchical cell radio network also includes a wireless local area network (WLAN), usually with spatial significantly more limited coverage by the radio. Cell communication that are covered by access points (AP) of the WLAN, with a diameter of up to several hundred meters are small compared to a normal cell cell radio. Examples of different standards for WLANs are HiperLAN, DECT, IEEE 802.11, Bluetooth, and WATM.

Access to user stations in a shared transmission medium is regulated in wireless systems with multiple access methods/ways multiplexing (MA). In these methods, multiple access transmission medium can be divided between user stations in the time domain (multiple access with time division multiple access - TDMA), frequency domain (multiple access frequency division multiple access - FDMA), code domain (multiple access code division multiple access - CDMA) or in the spatial domain (multiple access with spatial division multiplexing - SDMA). The possible combinations of multiple access methods.

In the methods of multiple access code division to the channels for communication to user stations used for specific user codes, so in an upward direction corresponding user station or downstream network device can distinguish between messages that are transmitted to the user device or from the user device, from the messages transmitted to other user devices or from these other user devices, by performing correlation processing of the received signal relative to the user specific code. It is possible that the device uses to send messages to multiple codes. In this case, different codes are used to distinguish between different used user station transmission channels, for example to distinguish between the channels for the transmission of useful information and channels for information transmission signaling, or to distinguish between channels of different services.

In document WO 2004/034608 A1 describes how to select the appropriate combination of transport formats (TFC). This addresses the situation where a user station uses two coded composite transport channel (CCTrCH). When this is checked whether the transmission power of both channels CCTrCH greater than the maximum allowable transmit power. If this is the case, then the data rate of one or both channels CCTrCH is reduced.

In the basis image is etenia lies the task of creating effective way radio when the user station to transmit messages uses many codes. In addition, they must be offered to the user station and a network device for implementing the method.

This task is solved by a method with the characteristics of paragraph 1 of the claims and the user station and the network device with the characteristics of subordinate clauses.

Preferred embodiments of the presented in the dependent claims.

In way radio user station transmits messages to the network station using the first code and the second message using the second code. The adoption of the first code user station is temporarily interrupted, and during the interruption introduces the application of the second code. In accordance with the invention, the first application code user station resumed depending on the transmission power, which is available for use the first code of the user station.

Codes used in the communication system, for example in the UMTS system to provide the ability to distinguish between messages transmitted through different channels. Thus, may vary from each other messages to multiple user stations, as well as reports one user station, which are sent on different channels. the case of the code in the UMTS system we are talking about combination code extension code and scrambling. Along with the first and second codes, consider a user station may also use other codes, for example, it is possible that corresponding to the invention method will be applied in respect of multiple first and/or second codes. The transmission of the first and second messages, the user station can be carried out in parallel, that is, the first and second messages can be sent simultaneously.

After some interval of time, during which both the first and second codes were used user station, using the first code is interrupted. This interrupt use of the first code has the consequence that during the interruption only the second message using the second code is transmitted from the user station. An interrupt can, for example, be caused by deterioration of the terms of transfer in the uplink direction, i.e. in the direction from the user station to the radio network. The deterioration in the terms of transfer may, for example, to user stations to become well-known due to the fact that, by the network station to the user station sends a demand for increased power transfer. A preferred manner, the first code during the interruption of its application is not assigned to another user station, and is assigned to be jwaamoj user stations, which does not use it to send messages only to temporary interruption interval.

The re-application of the first code depends on the transmission capacity available to the user station for use the first code. This capacity may, for example, be a really available for use the first code transmit power, or some future or granted in the future under certain conditions, transmit power, as, for example, transmit power, available after changing the transmission power, the subsequent application of the second code.

In the embodiment of the invention, transmit power, which is to use a custom station of the first code, depends on the maximum possible to use a custom station transmit power and the transmit power, which can be used by custom station for applying a second code. Possible to use the transmit power may, for example, be set by the hardware user stations, it may be specified by the network or via standard radio, it may depend on certain circumstances, for example, how many codes can note the change user station to transmit messages. So in the case of multiple user stations used transmit power, when the user station uses a lot of code, less than for the case when there is only one single code. The transmit power available for use the first code may be obtained, for example, possible to use a transmit power minus the power transmission, which can be used to apply the second code.

According to a preferred variant of the invention, the transmit power, which is available for use the first code of the user station, is determined by the user station during the interruption of the application of the first code. In this case, the user station itself may again decide to use the first code, i.e. without the involvement of a network station, if it determines that there is sufficient transmit power to use the first code.

It is preferable if, in the determination of the power transmission-side user includes the following parameters: the maximum possible to use a custom station transmit power, the current transmit power used by user station during the interruption of the application of Pervov the code to use the second code, and power transfer, other than the current transmit power used by user station during the interruption of the first application code to use the second code. Other values may participate in determining the user's transmit power, relevant to resume use. Due to the described according to a certain power transmitting user station can determine the amount of transmit power to the maximum available transmit power available for the first code, if there is a transition from the current applied to the second code power transfer to another applicable for the second code transmit power.

In another embodiment of the invention, transmit power, which is available for use the first code of the user station, determined by the network node terminating an application of the first code. In the case of network node may be talking about the network station or other device associated with the network radio station. Network radio station can request from the user stations to resume use of the first code by sending an appropriate message if the network side is determined that the first application code is available, sufficient power is here.

It is preferable if the network determining the transmit power used by the following values: information transfer rate used by user station at the current time to send messages using the second code, and the information on the transmission speed used by the user station immediately before the interruption of the application of the first code to transmit messages using the second code. The preferred way, both transfer rates refer only to the second message. The corresponding transfer rate can be determined at the network side in the case of a UMTS system, for example, from a combination of transport formats (TFC). Transfer rate associated with the determination of the power transmission on the network side in the sense that under given conditions of transmission and a predetermined reception quality in network radio message from the user station can be transmitted either with a higher transmit power and a higher transmission rate or a lower transmit power and lower speed transmission. The re-application of the first code or received on the network side the decision to resume may, in particular, to contact the criterion threshold, thus, for example, that if the transmission rate from the moment of interruption ISM is a high number, at least a certain value, then use the first code available sufficient transmission capacity, and the adoption of the first code may be again resumed.

Additionally or alternatively, in the determination of the power transmission on the network side may include information about the control signals transmit power, transmitted from the network station to the user station during the interruption of the application of the first code. From the difference between the power transmission to the time of the interruption of the application of the first code and the current transmit power, which is known on the network side due to transmission signals to control the transmit power, or may be defined on the network side conclusions can be drawn about the change of the conditions of transmission in the uplink direction, therefore, the transmit power available for use the first code. And in this case, the re-application of the first code or the network decision to resume may contact the criterion threshold, thus, for example, that when the transmit power would be reduced in a certain number of times, there is sufficient transmit power to use the first code.

When carrying out the invention it is in the case of the first message on the message channel HS-DPCCH (high is kosorotov control channel packet data), and in the case of the second message on the message channel DPDCH (dedicated physical data channel) or channel DPCCH (dedicated physical control channel). Channels DPDCH and DPCCH are dedicated channels in UMTS, while channel HS-DPCCH is a channel signaling in the uplink direction is used for HSDPA (high-speed access to packet downlink). Information about the service HSDPA in UMTS are contained in the document 3GPP TS 25.211, 3GPP TS 25.212, 3GPP TS 25.213 and 3GPP 25.214.

Corresponding to the invention a user station for a radio communication system includes means for transmitting the first message using the first code and the second message using the second code to the network radio station and means for interrupting the application of the first code and the continued application of the second time code interruption of the application of the first code and means for resuming the first application code depending on the transmission power, which is available for use the first code.

In the embodiment, a user station also includes means for determining the transmit power, which is available for use the first code. These tools can, depending on the result of determining the transmission power control mentioned among the countries to resume.

In accordance with the invention, a network device for a radio communication system includes means for receiving first messages transmitted using the first code and second messages transmitted using the second code from the user station and means for determining the transmit power, which is available for use the first code of the user station. Corresponding to the invention, the network device may also include means for indicating that the user station must use the first code to apply to messages. This indication is dependent on a certain transmit power.

Corresponding to the invention the user station according to the invention a network device, in particular, are suitable for implementing the invention method, and this also applies to variants of execution. To do this, they can contain additional suitable means. Corresponding to the invention the user station according to the invention, the network device can also be implemented through a set of interconnected devices with appropriate means.

The invention is illustrated below by the example of execution with reference to the drawings showing the following:

figure 1 is a fragment of a radio communication system of the UMTS standard,

figure 2 - schematic representation of the structure corresponding to the invention the user station and corresponding to the invention the network device.

Figure 1 shows the cell Z radio, in a simplified representation in the form of a circle, the base station NODE B, a radio communication system of the UMTS standard. The base station NODE B is connected with other devices on the network NET UMTS radio system of the UMTS standard. For clarity, not shown in figure 1 other base station of the cellular radio system of the UMTS standard. In cell Z radio base station NODE B is the user of the mobile station UE, which performs radio communication with the base station NODE B in accordance with the UMTS standard.

In radio systems UMTS different channels differ from each other codes. In this case, one user station can be used many codes. Figure 1 shows the case where the mobile station UE to the upward direction allocated to the first code C_HS-DPCCH and the second code C_DEDICATED, that is, the mobile station UE applies the codes C_HS-DPCCH and C_DEDICATED to transmit messages to the base station NODE B. Code C_DEDICATED corresponds to the allocated channels DPDCH (dedicated physical data channel) and DPCCH (dedicated physical control channel, the mobile station UE, which are used for the transmission of useful information (in the case of channel DDCH) and alarm (in case of channel DPCH) to base station NODE B.

Code C_HS-DPCCH corresponds to the signaling path of the upward direction (HS-HPCCH) HSDPA services. In the framework of the services provided HSDPA high-speed data transmission in the downstream direction, i.e. from the base station to the user stations, through the use of modulation methods of higher order in conjunction with the methods of repetition of the transmission, in which repetition transmission contain incremental redundancy. For data transmission in the downstream direction is applied channel HS-PDSCH (high speed physical downlink shared channel). The uplink HS-DPCCH is used to transmit positive or negative acknowledgment in the form of messages ACK / NACK with respect to the communications channel HS-DPCCH and information about the admission requirements on the user side (CQI - index of the quality of the channel) from the user station to a corresponding base station. Message ACK or NACK, the base station may determine whether the packet data channel HS-DPCCH adopted the custom station, or whether he was adopted correctly. From the value of CQI, the base station determines the transmission power that should be applied in a downward direction for channel HS-DPSCH.

We consider the case when the conditions of the transmission channel in the uplink direction between the mobile station UE and the base station NODE Fukudaya. The base station NODE B, which registers a reduced quality of signals received from the user station UE responds to this by the fact that it signals the mobile station UE to increase its transmit power. With continued deterioration of conditions of transfer of the mobile station UE increases the transmit power for code C_US-DPCCH and code C_DEDICATED. If continued deterioration of transmission has reached the maximum transmit power, the mobile station UE changes used for data transmission on the selected channel combination TFC. TFC is associated with certain data rates and coding. Under given conditions of transmission change TFC in combination with tunable power transfer occurs in such a way that the receiver of the reception quality remains essentially the same. Thus, TFC indirectly associated with the transmit power. Mobile station UE adjusts with the deteriorating conditions of transfer after reaching maximum transmit power TFC such that for the selected channels require less transmit power so that the transmission power for code C_S-DPCCH may be increased. Thus, the message signaling channel HS-DPCCH processed the preferred way to messages selected channels DPDCH and DPCCH. This is substantiated by those who, the ACK and NACK important for ARQ method HSDPA services.

With continued deterioration of transmission in the uplink direction, finally, TFC is achieved, which corresponds to the minimal transmit power for the selected channel. Further reduction of the transmission power for the selected channels is impossible without that user station UE will lose contact with the base station NODE B. In this case, the connection between the user station UE and the UMTS network would need to reinstall, which should be avoided. Therefore, the use of channel HS-DPCCH or relevant code C_S-DPCCH is interrupted. This interrupt can be initiated by that user station UE receives from the base station NODE B further requirement to increase the transmission power. If the user station UE determines that the combination of TFC can no longer adapt effectively to transmit power for dedicated channels could be reduced, then an interrupt occurs, the application channel HS-DPCCH.

After the user station UE is no longer transmits messages on the channel HS-DPCCH, all its transmit power available for both dedicated channels DPDCH and DPCCH. Therefore, TFC may change so that to send messages via dedicated channels DPDCH and DPCCH is used the maximum is th transmit power of the user station UE. At the same time has a great influence that the maximum possible transmit power, while the application code C_US-DPCCH and code-behind C_DEDICATED, usually less than if I had used only the selected channels DPDCH and DPCCH. The difference between these two maximum power transfer is denoted as Power Backoff (delay, power). This not only applies to user stations, in which the amplifiers within a large range display linear mode.

Code C_HS_DPCCH assigned to the user station UE for channel HS_DPCCH, after the interruption of its application is not assigned to other user stations. On the contrary, when the improvement of the conditions of transmission service HSD should again be renewed. In accordance with the invention resumes transmission of messages over the channel HS_DPCCH depends on the transmit power available for channel HS_DPCCH. Determining the transmission power and, thus, the decision to resume can be performed on the user side and network side.

If the available transmission power is determined on the side of the user, the user station UE should perform the calculation, which is presented below on a numerical example. Let the maximum transmit power of the user station UE for the case cohabitants only the selected channels DPDCH and DPCCH, is 21 dB mW. The maximum transmit power of the user station UE for the case when used as dedicated channels DPDCH and DPCCH and HS-DPCCH is 19 dB mW. Currently within the interrupt channel HS-DPCCH user station UE applies TFC with a data rate of 64 kbps and transmit power 20 dB mW. The maximum reduction in power transmission for channels DPDCH and DPCCH without deterioration of the reception quality to the base station NODE B with persistent permanent transfer can be achieved by going to the TFC with a baud rate of 2 kbps and transmit power 14 dB mW. The user station UE, also known private, which indicates the permissible ratio between the transmit power of dedicated channels DPDCH and DPCCH and transmit power channel HS-DPCCH. This private can be determined, the minimum required for the application of channel HS-DPCCH transmit power for a given transmit power for dedicated channels DPDCH and DPCCH. If the quotient is equal to 1, then channel HS-DPCCH, as a minimum, must be available transmit power 14 dB mW. This transmit power is indeed available, as the maximum transmit power is 19 dB mW, and the minimum applied transmit power for dedicated channels DPDCH and DPCCH is 14 dB mW.

After polzovateley the station UE through the above calculations have established, what's available for channel HS-DPCCH transmit power is sufficient, it applies the code C_US-DPCCH to transmit to the base station NODE IN its current CQI value. The base station NODE B, initiated by the reception of this message on channel HS-DPCCH, resumes sending messages HSDP in a downward direction to the user station UE.

Determining at the network side of the transmission capacity available for a channel, HS-DPCCH, is different from the calculation on the user side, as on the network side is not known really used the user station UE transmit power. In contrast, the known current TFC applied by the user station UE during interrupt channel HS-DPCCH, TFC applied to time establish application channel HS-DPCCH, and send time setting use channel HS-DPCCH signals for power control. The preferred way to determine on the network side power transmission relevant to resume channel HS-DPCCH is used, the criterion threshold: if the number of TFC increases towards higher transmission speeds higher than a specific number threshold value, the available transmit power for the code channel HS-DPCCH sufficient. Increase TFC in the direction of higher speed is th transmission indicates the improvement of the conditions of transfer. When choosing the threshold values, in General, should be taken into account that TFC under certain circumstances can increase only due to the establishment of the channel, HS-DPCCH, the threshold would be, therefore, to exceed these increases, which are not dependent on the transmission conditions. Additionally or alternatively may be also taken into account the change in the transmit power applied by the user station UE. From the summation of the requirements for changing the transmission power on the side of the user contained in the transferred since the interrupt channel HS-DPCCH to the user station UE, the network side is known, the total change in the transmit power on the user side since the interrupt channel HS-DPCCH. It can be applied with the threshold transmit power, for example the transfer of ten requirements "downgrade"from which the available transmit power is sufficient for the code channel HS-DPCCH. From a certain number of requirements to reduce the transmission power can be concluded about a noticeable improvement of the conditions of transmission in the uplink direction, so that under these conditions it is appropriate to resume services HSDP. It is possible that on the network side, along with the change of TFC and used on the user side power transmission, can acitivites the additional value specifically, for example, the delay parameter is the power to decide if there is sufficient transmit power to resume channel HS-DPCCH.

In cases of determining at the network side of the transmission capacity available for channel HS-DPCCH transmit power need not be calculated explicitly, and may implicitly follow from the presence of certain conditions, as, for example, changes in TFC and/or power transmission. Once on the network side is established that the available transmit power is sufficient for channel HS-DPCCH, the base station NODE B can again be passed to the user station UE message HSPDA in the downward direction. Since the current value of the CQI of the user station UE, due to the interruption of the application of channel HS-DPCCH, on the network side is not known, the transmit power in the downstream direction may be determined based on the minimum possible CQI values or on the basis of the last reported from the user station UE CQI values. By receiving this message HSDPA user station UE starts transmission of messages over the channel HS-DPCCH. The resumption of channel HS-DPCCH user station UE may also be initiated by the fact that she requested sent by the base station NODE B message directly on the transfer of its current value the CQI channel HS-DPCCH.

Defined as on the user side and network-side criterion for the renewal of the channel HS-DPCCH allows you to determine the appropriate time to resume services HSDP, after she was terminated, due to the poor conditions of transmission in the uplink direction. The above definition on the network side and the user side ensure that the use of channel HS-DPCCH is resumed only when the conditions of the transfer in the uplink direction is improved. Without the use of the invention, a method would be premature application of channel HS-DPCCH, which would lead to a "ping-pong" effect switching, since the resumption of channel HS-DPCCH with the same poor conditions of transmission in the uplink direction for the selected TFC channel would be reduced to a minimum in order to then install the application channel HS-DPCCH. Due to the fact that thanks to the invention of the earlier application channel HS-DPCCH can be avoided, conserve resources for services channel HSDP in a downward direction, in addition, due to a longer waiver application channel HS-DPCCH is generated less mutual interference.

Figure 2 schematically shows the structure of the user station UE and the base station NODE B. by means TRANSMIT C_HS-DPCCH and TRANSIT funds C_DEDICATED user station UE may send a message channel HS-DPCCH channels DPDCH and DPCCH. These messages are received by the base station NODE B by using the tools RECEIVE C_HS-DPCCH and RECEIVE C_DEDICATED. Means STOP C_HS-DPCCH user station UE enter the interrupt code is applied C_HS-DPCCH, while the application code C_DEDICATED remains unchanged. The re-application code C_HS-DPCCH is initiated by means STRAT C_HS-DPCCH. It managed to do this through the user station UE: TRANSMIT POWER C_HS-DPCCH, which is determined on the side of the user available capacity for application code C_HS-DPCCH, or, indirectly, by means of the base station NODE B: TRANSMIT POWER C_HS-DPCCH, which is on the network side determines the user available capacity for application code C_HS-DPCCH, after which the funds base station NODE B: STRAT C_HS-DPCCH prompt to the user station UE on the resumption of channel HS-DPCCH.
