The technical field to which the invention relates

The present invention relates to a method for data downlink in a mobile terminal in a mobile communication, and more specifically to a method of creating a data format for mobile communication and terminal implementing such method.

The level of technology

Fig. 1 illustrates an exemplary basic structure of a UMTS network (universal mobile telecommunication system) in accordance with the present invention and the technical field. UMTS includes a terminal (user equipment (UE)), UTRAN (terrestrial radio access network UMTS) and core network (CN). UTRAN includes one or more radio network subsystems (RNS). Each RNS includes a radio network controller (RNC) and a plurality of base stations (nodes)that are managed by the RNC. For a single node has one or more cells.

Fig. 2 illustrates the Protocol architecture of the radio interface is based on the specification of the radio access network 3GPP, between UE and UTRAN. As is shown in Fig. 2, the air interface Protocol has horizontal layers containing physical level, data link and network layer, and has a vertical plane containing the plane user plane (U), designed to transmit information about the data and control plane (the plane), before oznachennoe for transmitting control signals (alarm). The levels of the Protocol in Fig. 2 can be divided into the first level (L1), second level (L2) and third layer (L3) based on three lower layers of the model standard for interoperability of open systems interconnection (OSI), widely known in communication systems.

Each level in Fig. 2 will be described in more detail as follows. The first level (L1), namely the physical layer, provides a way of transmitting information to the top level by using a physical channel. The physical layer is connected to the top level, called level control the medium access (MAC), through the transport channel. Data is transferred between the MAC and the physical layer through the transport channel. Meanwhile, between different physical layers, namely, between the physical layer of the transmitting side and the physical layer of the receiving side, data is transmitted through the physical channel.

The MAC-level second level provides the service to the level of the control channel (RLC), its upper layer, through a logical channel. The RLC level second level can support reliable data transmission and to perform segmentation and concatenation of service data units (SDU) RLC delivered from the upper level.

The level of radio resource control (RRC)located in the lower part of the third level, is defined only in the control plane and manipul the plans managing transport channels and physical channels on the establishment, reconfiguration and release of radio-bearers (RB). The radio bearer refers to the service provided by the second level (L2) for data transmission between the terminal and the UTRAN. In General, the establishment of the radio bearer related to the definition of levels of the Protocol and characteristics of channels required to provide special services and install the appropriate essential parameters and ways of working.

When the RRC specific terminal and the level UTRAN connect to exchange RRC message with each other, the corresponding terminal is in a connected state RRC, and when the RRC specific terminal and the level UTRAN not connect the corresponding terminal is in the idle state. Connected state RRC of the terminal can be divided into state URA_PCH, CELL_PCH state, a CELL_FACH state and a CELL_DCH state. In order to reduce power consumption, the terminal in the idle state, the URA_PCH state or CELL_PCH intermittently take PICH (paging indicator), the physical channel SCCPCH (secondary common managing the physical channel, the physical channel, which convert the PCH (paging channel), a transport channel, using the method DRX (reception with breaks). During the other time intervals different from the duration of time codeprint PICH or SCCPCH, the terminal is in standby mode. In the art terminal, performs the method DRX is activated in each of the certain duration of the DRX cycle CN domain or in the particular duration of the DRX cycle UTRAN to take exclusive PI (paging indicator) terminal. In the present description exclusive PI terminal in the art can be used to inform specific terminal that the paging message will be transmitted to a specific terminal through the channel PCH. Channel PCH is divided into frames PICH duration of 10 MS, and one PICH frame consists of 300 bits. The first 288 bits of one frame is used for exclusive PICH terminal to transmit one or more exclusive PI terminal. Rear 12-bit single frame PICH do not convey. For the sake of convenience, the front part 288 bits channel PICH defined as PICH UE, and the rear part 12 bits is defined as the unused part of the PICH.

Fig. 3 is a flow diagram of signals illustrating the procedure of the RRC connection between the terminal and UTRAN in accordance with this technical field. As is shown in Fig. 3, to the terminal in the idle state was connected with RRC UTRAN, the terminal must perform the RRC connection procedure. The procedure of the RRC connection may include three stages: the transmission terminal messages connection request RRC in UTRAN (S1), transferred with the help of the UTRAN message RRC connection in the terminal (S2) and the transmission terminal messages complete setup RRC connection in UTRAN (S3).

Now will be described the transmission of HS-DSCH for transmitting high speed data in one terminal through the downward communication line in the art. HS-DSCH is the time interval of transmission (TTI) of 2 MS (3 time interval) and supports many different code modulation (MCS)in order to obtain high speed data transfer. Optimal performance can be achieved by selecting an MCS, which is most suitable for the situation of the channel. This can be used method of hybrid automatic repeat request (HARQ), which combines ARQ method and the coding method of the channel to produce reliable data transmission.

Fig. 4 illustrates a Protocol stack HS-DSCH in accordance with this technical field. As is shown in Fig. 4, a block of data that is passed from level RLC SRNC is transferred to the object MAC-d, which manages the special channel through DICH or DCCH logical channel, and the corresponding data are transmitted to the MAC-hs node via the MAC-c/sh/m CRNC. In the present description MAC-d is the object's MASS, which manages the special channel, the MAC-c/sh/m is the object MASS, which manages the shared channel, and the MAC-hs is an object MAC, which manages HS-DSCH.

Physical channel HS-PDSCH is used to transmit the HS-DSCH transport channel. HS-PDSCH has a fixed allocation ratio 16 and corresponds to the code channel is ment, selected from the set of codes sewage reserved for data transmission on the HS-DSCH. If transmission of documents perform relative to one UE, many codes sewage appointed within the same podagra HS-PDSCH. Fig. 5 illustrates the structure podagra and time interval HS-PDSCH. HS-PDSCH transmits symbols modulation QPSK or 16 QAM. In Fig. 5 'M' indicates the number of bits per modulation symbol. Namely, in the case of QPSK 'M' is 2, and in the case of 16 QAM 'M' is 4.

Fig. 6 illustrates a channel configuration in accordance with this technical field.

As is shown in Fig. 6, to transmit user data through the HS-DSCH, the control information for the HS-DSCH shall be transmitted through HS-SCCH (high speed shared control channel) downlink and HS-DPCCH (high speed special physical control channel) uplink communication. In the present description DPCH (dedicated physical channel) is bidirectional physical channel, which convert DCH transport channel, and is used to transfer exclusive data terminal, and an exclusive control information L1 terminal, such as the control signal power required for power control closed loop. In addition, the F-DPCH (fractional special physical channel), the channel downlink, a physical spacecraft is scarlet which passes several DPCH using a single code channel. In the present description one F-DPCH does not convey exclusive data terminal (or special data terminal) multiple terminals, and it is used to transfer the monopoly control information L1 terminal of the multiple terminals together, such as the control signal power required for power control closed loop. If there is a channel (F-DPCH downlink channel (F-DPCH uplink connection also works. In Fig. 6 UE1, UE2 and UE3 use the F-DCPH through one channel code, in this case, each terminal provides DPCH in an upward direction.

HS-SCCH physical channel downlink transmit with a distribution factor of 128, and it has a speed of 60 kbit/s Fig. 7 illustrates the structure podagra HS-SCCH. Information transmitted through HS-SCCH downlink, can be roughly divided into information of transport format information associated with resources (TFRI), and information associated with HARQ, and, in addition, information about the identifier of the UE (namely H-RNTI (temporary identifier radio HS-DSCH), which is intended to provide information about a particular user, which mask the ID, and then pass.

Fig. 8 depicts the encoding scheme for the HS-SCCH based on the above information.

HS-DPCCH transmits the alarm feedback uplink communication associated with data transmission on the HS-DSCH. HS-DPCCH, a special channel for a specific terminal, it works together with the DPCH uplink communication and a descending line with the ides. Alarm feedback includes information of the ACK (acknowledgment)/NACK (negative acknowledgment) for HARQ and CQI (quality indicator channel). The frame of the HS-DPCCH includes five podkatov. Each podcat has a duration of 2 MS, and one podcat includes first through third time intervals, namely three intervals of time. Each time interval of podkatov carries the following information: information ACK/NACK, which is transferred in the first time interval of podkatov HS-DPCCH, and CQI, which is transmitted through third time intervals of podkatov HS-DSCH. HS-DPCCH transmit always together with PDCCH uplink communication. CQI transmits information about the state of the radio downlink, received from the measurement results UE CPICH (common pilot channel), and ACK/NACK provides information ACK or NACK on the service user data, which is transmitted through the HS-DSCH in accordance with the HARQ mechanism. Fig. 9 illustrates a frame structure for HS-DPCCH uplink connection.

In the art, when the HS-DSCH transmit at a particular terminal, an HS-SCCH indicates an exclusive H-RNTI (temporary identifier radio HS-DSCH). Meanwhile, if the HS-DSCH transmit to multiple terminals, HS-SCCH indicates a common H-RNTI. In addition, in the art, the MAC PDU HS-DSCH does not include the identifier of the terminal (UE ID, naming UE).

In D. the authorized technical field in the specific case, the radio network can transmit the HS-DSCH in a particular terminal, which is not assigned to the exclusive H-RNTI of the terminal. In this case, because a specific terminal does not have exclusive H-RNTI of the terminal, the network informs the specific terminal of the transmission of HS-DSCH through a common H-RNTI. Then specific terminal cannot determine that the transmission of HS-DSCH was intended for it, which is problematic.

The implementation of the invention

The present invention is applied to communication systems UMTS communication device and method that can transmit data downlink to the mobile terminal. However, the present invention is not limited to being, and may be applicable to any method of a wired/wireless communication.

The basic concept of the present invention provides a method in which only a specific terminal can receive data through a common data channel (e.g., HS-DSCH), when using the common identifier of the terminal (for example, a common H-RNTI). In addition, the present invention provides a new MAC PDU format that can perform such a method. Namely, the mobile terminal 1) adopt specific common identifier (e.g., H-RNTI) via the control channel (e.g., HS-SCCH)associated with the shared the data transmission channel, 2) check whether the header of the MAC PDU transmitted using the shared data channel, exclusive identifier of the terminal (for example, H-RNTI), and 3) if the header includes a exclusive identifier of the terminal, the mobile terminal obtains exclusive identifier of the terminal, and if the exclusive identifier of the terminal is intended for the rolling of the terminal, the mobile terminal processes the MAC PDU, as his own.

In the present invention, the MAC PDU format used for transmission of HS-DSCH specified using HS-SCCH, determined in accordance with the H-RNTI, the terminal ID, received via HS-SCCH. Namely, if the terminal ID is different, the MAC PDU may be different. In other words, depending on whether the H-RNTI exclusive terminal or General, the transferor (net) passes another MAC PDU format. The receiving side (terminal) checks whether the H-RNTI exclusive terminal or the common H-RNTI and decode the MAC PDU in accordance with the appropriate format.

The terminal receives the HS-SCCH and gets the identifier of the terminal H-RNTI, determines the format of the MAC PDU passed through the HS-DSCH, in accordance with the received H-RNTI and rasformiruyut adopted MAC PDU in accordance with a specific MAC PDU.

Now will be described embodiments of the present invention with reference to Fig. 11 at Phi is. 13.

Fig. 11 illustrates the format of the MAC PDU in accordance with the first embodiment of the present invention. In Fig. 11 the header of the MAC-hs is some type of MAC header. The header of the MAC-hs is an object MAC, which manipulates the HS-DSCH, and the MAC with an object that manipulates the shared transport channel.

Fig. 12 is a flowchart of a sequence of steps illustrating the operation of the terminal, which has received MAC PDU in a format that is shown in Fig. 11. The present invention will be described with reference to Fig. 11 and Fig. 12. When the terminal receives the HS-SCCH (for example, a control channel associated with HS-DSCH) and acquires an exclusive H-RNTI of the terminal from the frame HS-SCCH (S11), the terminal receives MAC PDU in a format that is shown in Fig. 11, of the frame of the HS-DSCH, which is converted into an HS-SCCH (S12). In this case, the header of the MAC PDU, as shown in Fig. 11, does not include the identifier of the terminal, such as C-RNTI (temporary ID cell radio network), U-RNTI H-RNTI. Therefore, the terminal recognizes (determines)that the header of the MAC PDU does not include the identifier of the terminal, and recognizes that the adopted MAC PDU is configured such that the header of the MAC PDU does not have the ID of the terminal (for example, C-RNTI U-RNTI H-RNTI) (S13, S14). If the exclusive H-RNTI of the terminal is identical to the exclusive H-RNTI of the terminal, stored in the term the Le (S16), the terminal determines adopted PDU MAC as your own and transmits a corresponding MAC PDU to the upper level WT (S17). If the exclusive H-RNTI of the terminal is not identical, the terminal discards the adopted MAC PDU (S18).

When the terminal receives the HS-SCCH and acquires an exclusive H-RNTI CCCH or a common H-RNTI of the frame HS-SCCH, if the terminal receives MAC PDU in a format that is shown in Fig. 11, of the frame of the HS-DSCH, which is converted into the frame of the HS-SCCH, the terminal determines that the header of the received MAC PDU does not include the identifier of the terminal. In this case, after receiving the MAC PDU terminal transmits the corresponding MAC PDU to the upper level MAC.

Fig. 13 illustrates the format of the MAC PDU in accordance with a second embodiment of the present invention. In Fig. 13 the header of the MAC-hs and MAC-c are types of headers WT. The header of the MAC-hs is an object MAC, which manipulates the HS-DSCH, and the MAC with an object that manipulates the HS-DSCH, and the MAC with an object that manipulates the shared transport channel.

Fig. 14 is a flowchart of a sequence of steps illustrating the operation of the terminal, which has received MAC PDU in a format that is shown in Fig. 13.

If the terminal receives the HS-SCCH and receives specific common H-RNTI of the frame HS-SCCH (S21), the terminal determines that the header of the MAC PDU MAC, which is taken from the frame of the HS-DSCH, which conversions is between H-SCCH, includes the identifier of the terminal (S22 through S24). In this case, the terminal ID included in the MAC header, is U-RNTI, as shown in Fig. 13. Specific common H-RNTI, ID, which is jointly separated and used by many terminals, serves to inform that the MAC header includes the identifier of the terminal.

If the identifier of the terminal (namely U-RNTI)that is included in the MAC header that is identical to the identifier stored in the terminal (S25), the terminal determines that the adopted MAC PDU is intended for the terminal, and transmits a corresponding MAC PDU to the upper level WT (S26). If the terminal IDs are not identical, the terminal discards adopted PDU (S27).

Fig. 15 is a principal block diagram of the terminal according to the embodiment of the present invention.

Now will be described the configuration and operation of the terminal according to the embodiment of the present invention with reference to Fig. 15.

If you receive an exclusive identifier of the terminal is not identical to the monopoly of the terminal ID stored in the terminal, after comparison module 102 processing discards adopted MAC PDU.

The module 102 processing determines the format of the MAC PDU used for transmission of HS-DSCH, MC is connected via HS-SCCH, in accordance with the identifier of the terminal H-RNTI, which is passed through the HS-SCCH.

Module 101 of the receiving terminal 100 receives the HS-SCCH, and the module 102 processing receives the identifier of the terminal H-RNTI from a received HS-SCCH, determines the format of the MAC PDU passed through the HS-DSCH, in accordance with the received H-RNTI, and handles the received MAC PDU in accordance with a specific MAC PDU format.

Exclusive terminal ID included in the header of the MAC PDU is U-RNTI, which indicates a specific terminal in one UTRAN. Specific common identifier is H-RNTI.

The module 102 processing may be called by the controller, and the meaning of the title of the module 102 processing does not limit the function and operation configuration. Module 101 of the reception may be called by the RF module.

FIELD: information technology.

SUBSTANCE: method and apparatus by which a mobile station receiving a point-to-multicast transmission from a radio access network (RAN) of a wireless communication system sends information to the RAN used when the mobile station moves to a neighbouring cell for receiving the transmission; in particular, the mobile station indicates to the RAN whether cell reselection parametres for the neighbouring cell have been received, and/or whether neighbouring cell information indicating parametres for continuing to receive the transmission in the neighbouring cell have been received by the mobile station. In a typical embodiment, the mobile station indicates not only whether parametres for receiving the transmission in the neighbouring cell have been received, but which set of parametres have been received. The information used in the mobile station moves to the neighbouring cell is sent to the RAN in an acknowledgment message uplinked on a packet access control channel.

EFFECT: availability of cell reselection parametres for a new cell.

SUBSTANCE: methods and systems are described, which provide half-duplex communication in system of duplex communication with frequency division of channels (Frequency Division Duplex, FDD). Communication in FDD system may be divided into half-duplex interchanges, the terminal may accept reception within a single time period and may transfer within a different time period. Network of access in FDD system may use half-duplex circuit, to realise communication with access terminal, which is not capable of simultaneous receipt and transfer, using half-duplex interchange. Besides, network of access may use duplex circuit, to realise communication with access terminal, which is capable to receive and transfer simultaneously.

EFFECT: realisation of duplexer in system with high throughput capacity.
