The technical field to which the invention relates.

[1] the Invention relates to the E-UMTS (developing a universal system for mobile communications), in particular to a method of receiving data in a mobile terminal.

The level of technology

[2] To support broadband wireless access (e.g., WiMAX technology for broadband microwave access) there are different types of radio broadband wireless access technologies such as 3G cellular connection (e.g., universal mobile telecommunications system "UMTS", broadband multiple access code division multiple access ("W-CDMA" and so on) and multiple access technologies based on the use of multiple carrier frequencies (for example, technology that uses multiplexing orthogonal frequency division is "OFDMA", OFDMA-TDMA, OFDMA-CDMA, and so on). Multiplexing (seal) channels with orthogonal frequency division includes the usage of subchannels at least four types ("OFDM"; "Flash OFDM" - "FD" for emergency communications; "sOFDMA" extensible "OFDMA"; and "OFDMA").

[3] the Multiplexing orthogonal frequency division "OFDM" includes splitting the radio signal into multiple Podshivalov (subsignals) smaller size, which are then simultaneously transmitted to the receiver at different frequencies. Multiplexers is their orthogonal frequency division "OFDM" - this type of transmission using multiple carrier frequencies, where all frequency subcarriers orthogonal to each other. Certain standards IEEE and 3GPP standards apply to different aspects of multiplexing orthogonal frequency division "OFDM".

[4] figure 1 and 2 shows a typical frame used in the technology "OFDM". One frame has duration of 10 MS (milliseconds) and consists of 20 subbarow having a duration of 0.5 MS. Each Subcat may consist of a block of resources "RB", containing data or information, and the cyclic prefix, the prefix "CP", which is a restrictive interval required for normal modulation OFDM (but are not required for the technology "OFDM" with the formation of pulses, that is, OFDM/OQAM). The duration of Subhadra corresponds to the minimum time interval for transmission "TTI".

[5] figure 3 shows the basic structure of the reference signal downlink consisting of known reference symbols. Namely, shows the character of the physical channel in the frequency domain (the domain). In other words, the information channel coding, interleaving and modulation data (i.e. information level 3) is displayed in the time/frequency characters "OFDM". The characters "OFDM" can be arranged in the form of "M" successive subcarriers frequencies for "N" consecutive si the oxen "OFDM".

[6] Here it is assumed that each subcode there are 7 characters "OFDM" (where the length of the prefix "SR" small). When the length of the prefix "SR" or other frame structure the basic structure of the reference signal downlink will be slightly different.

[7] the Reference symbols (i.e. the primary supporting characters) are in the first symbol "OFDM" each subcode assigned for transmission on the downlink. This rule applies as for full duplex frequency division channels "FDD"and duplex separation by time "TDD", for both long and short prefixes "CF". Additional reference symbols (i.e. secondary supporting characters) are in the third last character "OFDM" each subcode assigned for transmission on the downlink. This rule applies both to "FDD"and "TDD", for both long and short prefixes "CF". However, for full duplex frequency division channels "FDD" it is necessary to establish whether secondary supporting characters.

[8] figure 4 shows an example structure of a developing universal mobile systems "E-UMTS", applicable in the present invention.

[9] Developing a universal system of mobile communications "E-UMTS is a system, which is the result of the evolution of the University of the universal mobile systems "UMTS", and currently, the standards organization 3GPP is working on its standardization.

[10] As shown in figure 4, the network is developing a universal system of mobile E-UMTS" usually consists of developing a universal terrestrial radio access network E-UTRAN and core network. Network E-UTRAN consists of a terminal (that is, the user device UE) and base station (i.e. "Node"or "Node-eNB"), as well as access gateway ("AG"), located at the output of the network system (E-UMTS and connected to one or more external networks. The access gateway AG" can be divided into the module that handles the user traffic (user data stream), and the module that handles management traffic (data flow control). In this case, the access gateway AG, which handles the traffic of the user, and the access gateway AG, which handles management traffic can communicate with each other through the newly defined interface. For one base station Node-eNB may exist one or more cells. Between base stations Node-eNB for transmission of user traffic and management traffic can use the interface. The core network CN may consist of nodes, etc. used for registration, and other functions for the user terminal UE and the access gateway AG". Additionally, and in order to use the interface, discriminating network E-UTRAN and core network.

[11] in Addition, in the network system (E-UMTS may be a server control plane "CPS", which performs the functions of management radio communication (wireless communication), an element for controlling radio resource "RRM", which performs control functions radio resource element for mobility management "MIU", which performs the functions of mobility management for the mobile terminal. It should be understood that the specific names of these elements in different networks may vary.

[12] figure 5 shows a sample architecture (structure) of the Protocol of the radio interface between the mobile terminal and the network UTRAN (network terrestrial radio access systems "UMTS"). The interface Protocol radio figure 5 horizontally includes a physical layer, the channel layer data and network layer, and vertically includes a user plane for transmitting user information and a control plane for transmitting control signals. The interface Protocol radio figure 5 can be divided into level 1 (L1), level 2 (L2) and level 3 (L3) based on three lower layers of an interaction model of open systems interconnection (OSI), is well known in the technology of communication systems.

[13] the Physical level (i.e. level 1) uses physical channel is for providing data transmission services upstream level. The physical layer is connected to the above control level media access MAC via a transport channel, and data is transferred between the physical layer and management layer the medium access MAC via this transport channel. In addition, data transfer between the respective different physical layers, namely, between the respective physical layers of the transmitting side (transmitter) and a receiving side (receiver)through a physical channel.

[14] the Modulation of the physical channel is performed by means of multiplexing orthogonal frequency division "OFDM", using time and frequency as radio resources.

[15] the access control environment "MAC" level 2 provides level control channel "RLC" (which is the upstream level) through a logical channel. Level control channel "RLC" tier 2 supports reliable data transfer. It should be noted that if the function control channel "RLC" implemented at the level of access control environment "MAC" and executed them, the level control channel "RLC" may be absent. The level Protocol packet data convergence "PDCP" level 2 performs the function of header compression, which reduces enojoy information management, to the data transmitted using the packet Internet Protocol "IP", such as IPv4 or IPv6, could effectively be transmitted through the interface radio communication (wireless communication) with a relatively small bandwidth.

[16] the Level of radio resource management "RRC", located in the lower part of the level L3, defined only in the control plane and provides management of logical channels, transport channels and physical channels in relation to the establishment, reconfiguration and termination or cancellation wideband radio channels "RB". Here the radio "RB" is a service provided by the second level (L2) for data transmission between the terminal and the network UTRAN".

[17] the "NAS" (layer without access), located at a higher level than the level of radio resource management "RRC", the function of the session management connection management, mobility, etc.

[18] Among the channels used for data transmission on the downlink from the network to the mobile terminal, the channel is broadcast "VSN", used for transmission of system information, and the shared channel "SCH", used for transmitting user traffic or control messages. Accordingly, the traffic for the multicast or broadcast or control with the communication downlink can be passed on downward shared channel "SCH" or on a separate (individual) downward channel "sit" (channel multicast).

[19] as for the channels used for data transmission on uplink communications from the mobile terminal in the network, there is a channel random access "RACH used for transmitting an initial control message and the shared channel "SCH", used for transmitting user traffic or control messages.

[20] in Addition, as for the logical channels that are located at a higher level than the transport channels, and displayed on transport channels, there are "SSN" - channel broadcast, "RSN" channel search management call (paging channel), "SSN" control channel, "MSN" control channel multicast transmission, "MTCN" - channel traffic, multicast, etc.

The invention

Technical problem

[21] In the framework of the existing technology shared control channel "SCCH", which is a channel, transmitting the management information is shared channel "SCH", always passes the ID of the mobile terminal UE" to identify the mobile terminal. Accordingly, when data is shared channel for a variety of mobile terminals is transmitted shared channel "SCH", the shared control channel "SCCH" must pass many identificat the ditch mobile terminal, to be used by multiple mobile terminals. Thus, causes difficulty large size (or volume) control information that is transmitted on the control channel "SCCH".

[22] in Addition, in the framework of the existing technology, the mobile terminal should receive channel "SCH" in each and every frame. However, because the data that must be read on the mobile terminal (that is, data destined for the terminal UE"), in fact, is transmitted only in certain moments of time, the reception channel "SCH" for each frame is associated with excessive consumption of battery.

Technical solution

[23] the Aim of the present invention is to solve the above problems of the existing technology. In the present invention proposes a method of receiving data for the mobile terminal that can minimize the size (or volume) data generated in the process of sending and receiving data, and is able to minimize the battery consumption of the mobile terminal.

Preferred modes of carrying out the invention

[32] One aspect of the present invention is understanding the authors of the present invention the above described difficulties and disadvantages associated with current technology and explain more in the future. On the basis of this understanding was established the present invention.

[33] the Present invention provides for a mobile terminal, the method of receiving data, is able to minimize the size (or volume) data generated during transmission or reception of data, which in turn can minimize the battery consumption of the mobile terminal.

[34] Properties of the present invention can be implemented in the mobile communication system, for example system "UMTS". However, the properties of the present invention can also be implemented in communication systems of other types, operating according to other standards.

[35] it Should be noted that the features of the present invention relate to issues regarding the long-term development "LTE2) of the 3GPP standard. Thus, 3GPPS TS 25.813 (LTE TR), its relevant sections and parts, as well as various design improvements relate to the present invention. Such improvements and development led to the use of a certain prefix (letter "E") to denote the various network objects (for example, the node in the underlying network "eNode B"), levels, protocols, channels, etc. But it should be clearly understood that such designation and other terminology are purely exemplary and therefore can be replaced or updated later) as a result of the discussions that are underway or will be conducted.

[36] in Order to minimize the size (or volume) data generated in the process of sending or receiving data, and to minimize the battery consumption of the mobile terminal, the network communication (mobile) transmits to the terminal UE" on the second channel information is the situation identifier, which indicates whether the data transmitted on the first channel, data of the selected channel terminal UE or data shared channel. The terminal periodically or pereodicheski takes a second channel, and if the information ID received on the second channel, indicates that the data are the data shared channel, the terminal receives the data shared channel on the first channel.

[37] the First channel may be a shared channel "SCH"and the second channel may be a shared control channel "SCCH", which transmits the management information channel "SCH".

[38] Network communications (mobile communications) may be a core network node "eNode B" Node eNB"), data of the selected channel terminal "UE" can represent the data of the logical channel DTCH" - dedicated channel traffic, or "DCCH" - a dedicated control channel and the data channel may be data of the logical channel "SSN" - shared control channel, or channels "SSN" - channel broadcast, "MSN" control channel multicast transmission, "MTCN" - channel multicast traffic transfer, "RSN" channel search management call (paging channel), etc.

[39] Information identifier for the data shared channel dedicated control channel "SCCH"may include identifier information of the logical channel type, which means that the data belong to a logical channel among the channels: "SSN" - shared control channel, or "SSN" - channel broadcast, "MCCH" control channel multicast transmission, "MTCH" - channel multicast traffic, "RSN" channel search management call (paging channel), etc.

[40] the Network communication (mobile communication) can convey information about the transmission time corresponding to a logical channel is transmitted via a shared channel, "SCH", or information about a transmission time corresponding to the shared channel "SCH". The terminal may periodically take the second channel or the first channel in accordance with the time information of the transmission received from the radio communication network.

[41] figure 6 shows a diagram illustrating features of the present invention, for demonstration that can be placed blocks of control information and the resource blocks in each potcake versus frequency and time.

[42] the Structure (format) podagra relative to the frequency domain and the time domain can be understood with the help of 6. Namely, a separate podcat has a temporal duration of 0.5 MS and contains 7 characters (parts of) the multiplexing orthogonal frequency division "OFDM".

[43] In the first part podagra contains control information (i.e. the UE is alausa information levels L1/L2, FCCH, SCCH and the like), while the remainder of podagra can be placed blocks resources "RB" in the form of one or more "chunks". Here, the resource block may take the entire period of time podagra (except for the period of intended for control information) or some part thereof. In addition, each resource block "RB" may use a specific frequency range (i.e. a certain number of carrier frequencies).

[44] Axis frequency can be called scalable bandwidth of the cell, which usually occupies a frequency range of 1.25~20 MHz. In scalable bandwidth of the cell there are many subcarriers frequencies. In this range of frequencies when transmitting system information is commonly used so-called Central frequency (approximately 10 MHz).

[45] In the existing technology, this system is fixed. Although this allows the terminal to easily read the system information, add new information impossible. In contrast, the present invention provides flexibility (agility) at least part of the system information.

[46] For this purpose, the present invention divides (or splits, or conducts differences) system information on the basic system information (for example, the main unit of the information: "MIB") and auxil athelney (or secondary) system information (for example, the block system information: "SIB").

[47] the main Unit of information "MIB" is passed to a static image (e.g., via a broadcast channel "VSN" data static way), while the block system information "SIB" is passed to the dynamic manner (e.g., downward through the shared channel "SCH" data dynamically). Here, the transmission data dynamically means that can be used in different frequency ranges and different duration time.

[48] For each frame unit of the main information MIB contains information about the location of each block in the system information "SIB". Exactly, a specific range of frequencies (i.e. frequency subcarriers) and a specific duration of time for each block in the system information "SIB", allowing the terminal UE" properly read the relevant system information blocks "SIB".

[49] in a Similar manner for each podagra in the frame control information (located in the first part) contains information about where each resource block "RB". Namely, the specified frequency range and a specific duration of time for each resource block "RB"to allow the terminal UE" properly read, the corresponding resource blocks "RB".

[50] See what's above principles, in the General form shown in Fig.6, are addressed in more detail in the following description using Fig.7.

[51] figure 7 shows a sample implementation of the method of data reception to the mobile communication terminal in accordance with the present invention.

[52] figure 7 each shared control channel "SCCH" (that is, the control information channel in the form of "SCCH1", "SCCH2", "SCCH3", "SCCH4") can be transmitted using the frequency and time that is different from the frequency and time shared channel "SCH"and be transmitted once in each potcake. One podcat may have a duration of 0.5 MS, with each shared control channel "SCCH" is transmitted using one or two characters that make up the corresponding podcat. Single podcat consists of 6 or 7 characters, and, thus, different symbols are corresponding to different periods of time (duration).

[53] it should be noted that for different purposes may require multiple shared control channels "SCCH". For example, different types of traffic can be transmitted only intermittently. In addition, the bandwidth limitations of the mobile terminal (terminal "UE") may be required to pass at certain time intervals, only the data (or information) of a particular type. the thus, the the terminal UE is not required to read every podcat.

[54] figure 7 shared control channel "SCCH" (for example, channels SCCH1", "SCCH2", "SCCH3", "SCCH4"), which is transmitted in one potcake, transmits control information related to the shared channel "SCH" as a "SCH1", "SCH2", "SCH3", "SCH4"), corresponding podagra. The control information transmitted over a single shared control channel "SCCH", may contain the ID (identification) of the mobile terminal, an ID (identification) service multicast and ID (identification) logical channel. The ID of the logical channel may report whether the data transmitted in potcake corresponding shared channel "SCH", data for the selected channel of the mobile terminal (for example, a dedicated control channel "DCCH", or a dedicated channel traffic "DTCH") or data for the shared channel. In particular, if the data are intended for the shared channel, the identifier of the logical channel according to the type of common channel (i.e., "SSN" - channel broadcast, "RSN" channel search management call (paging channel), "MSN" control channel multicast transmission, "MTCN" - channel multicast traffic, "SSN" - shared control channel).

55] the Mobile terminal may receive periodic manner various shared control channels "SCCH", each of which has a corresponding period (for example, every four podagra). For this purpose, the base station node "eNode B" ("Node eNB"), the mobile terminal transmits information about the period. Then the mobile terminal can accept podckaji each shared control channel "SCCH" periodic manner, in accordance with information about the period provided by the base station.

[56] the Mobile terminal receives the ID of the logical channel from the received shared control channel "SCCH", and using the received identifier of the logical channel of the mobile terminal can determine whether the data transmitted over the shared channel "SCH", data for the selected channel or the data for one channel: "BCCH - channel broadcast, "RSN" channel search management call (paging channel), "MCCH" control channel multicast transmission, "MTCN" - channel multicast traffic, "SSN" channel control (i.e., a common channel).

[57] If the identifier of the logical channel indicates a shared channel, the mobile terminal receives podcat corresponding shared channel "SCH", so as to receive data shared channel.

[58] Thus, in accordance with the management of the radio terminal "U" periodically receives channel SCCH1" or one of the channels "SCCH2", "SCCH3" and "SCCH4". Thus, the base station node "eNode B" ("Node eNB"), you may specify the shared control channel "SCCH", which is supposed to make certain the terminal UE".

[59] figure 7 podcat shared control channel "SCCH" and podcat shared channel "SCH", which appears on podcat channel SCCH do not coincide, and these podckaji different. Accordingly, for example, for terminal "UE", which periodically receives the shared control channel "SCCH2", if you pass the ID of the terminal UE" (displayed on potcake shared control channel "SCCH2), or if the information is needed (required) information is taken podcat shared channel "SCH2" (which is passed in one potcake after podagra shared control channel "SCCH2"). In other words, 7 to terminal "UE", which periodically receives the channel SCCH2"if the information in the shared control channel "SCCH2 from podagra #2 indicates that should read some of the information in the shared control channel "SCH2", the terminal UE reads the shared channel "SCH2" podagra #3.

[60] it Should be noted that information in a separate shared control channel "SCCH"(that is, control information) should not be attributed only to the corresponding podagra, located in one potcake next. In other words, information in a shared control channel "SCCH" can provide information (i.e. the location of the resource block based on the characteristics of time and frequency) on potcake, which should be read next in two or more pocketrak. It may be necessary for several reasons, for example when a relatively large amount of data to be read, when performing continuous planning and other

[61] In the present invention, the network communication (wireless communication) to send the identifier information, which indicates whether the data transmitted on the first channel, data of the selected channel terminal UE or data shared channel, the terminal UE" on the second channel. The terminal receives the second channel is periodic or aperiodic manner, and if the information ID received on the second channel, indicates that the data are the data shared channel, the terminal receives the data shared channel on the first channel. The use of these procedures allows to minimize the size (or volume) data generated in the process of sending and receiving data, and to minimize the battery consumption.

[62] it Should be noted that the shared control channel is "SCCH" can also be described in other words. Namely, the control information transmitted by the network, can be called a management information levels L1/L2 channel FCCH"shared control channel "SCCH", etc.

[63] the Present invention provides a method of receiving control information by a terminal in a mobile communication system having a single control channel and multiple shared channels, as well as having a network that periodically transmits control information on a control channel, the method comprising: periodically receiving the control channel; detection at a certain time identifier in the received control channel and receiving data through a shared channel indicated by the control information, which includes the detected identifier.

[64] moreover, the present invention provides a method of transmitting control information by a network terminal in a mobile communication system having a single control channel and multiple shared channels, the method comprising: periodically transmitting the control channel and data transmission through a specific shared channel indicated by the control information that includes the identifier is detected at a certain time point in the control channel.

[65] the Identifier may be an identifier of the terminal or ID on the channel. At least one of the shared channels can be "SSN" control channel, "SSN" - channel broadcast, "MSN" control channel multicast transmission, "MTCN" - channel traffic, multicast, or "RSN" channel search management call (paging channel). The receiving of control information may be transmitted on the control channel. Control information and data can be received (transmitted) in the same potcake. Control information and data can be received (transmitted) in various pocketrak. The control information may indicate the time and frequency information for the data in one podagra or different serial pocketrak. The control information may include at least one of the following: management information channels "SCCH", "FCCH" and the control information of the levels L1/L2. The control information may indicate at least one of the following: a frequency parameter, a time parameter and the size parameter data to be read. The frequency parameter can relate to the characters, the setting time refers to the carrier frequency, and the size parameter refers to the symbols and subcarriers frequencies.

Service signals may be sent to indicate the selected PC mode. If the "up-down" PC mode is selected, the base station assesses the quality of the received signal for the terminal and sends PC commands in order to instruct the terminal to adjust its transmission power. If the delete-based PC mode is selected, the base station sends delete indicators which indicate whether code words received from the terminal are deleted or not. In both PC modes, the terminal controls its transmission power based on a power control feedback (e.g. a PC command and/or delete indicators) in order to attain the target level of efficiency (e.g. target deleting frequency for code words). Delete indicators may also be used for handover.

EFFECT: reduced noise and achieving high efficiency for all terminals.

SUBSTANCE: system uses switching ports to facilitate allocation and utilisation of sub-carriers. In one version, switching ports may be divided into several sub-zones, wherein each sub-zone includes a configurable number of switching ports. Switching ports in each sub-zone may be configured or moved based on a commutator function. After rearrangement, the switching ports in all sub-zones can be mapped to sub-carriers based on local or global switching. In another version, a set of switching ports can be mapped to a set of sub-carriers. A switching port can be mapped to an unavailable sub-carrier and can be re-mapped to another available sub-carrier. In yet another version, a set of switching ports can be mapped on a set of sub-carriers distributed (e.g. uniformly) on all sub-carriers, but avoiding sub-carriers in a reserved zone.

EFFECT: high efficiency of allocating and mapping resources in a wireless communication system.
