- the embodiment of the present invention augments and modifies the control signaling on the HS-SICH channel, so that the HS-SICH channel can feedback the UE to confirm the received dual stream data, and Node B recommends the number of data streams in the next TTI and the transport block size and modulation mode on each data stream, enabling the HSPA+ system to better support MIMO technology, thereby increasing data transmission rate and system throughput.
- the -SICH channel will degrade the reception performance of the channel.
- the code channel resource carrying the HS-SICH is added to ensure that the signaling of the channel can be better received.
- each part of the signaling information on the HS-SICH channel may be multiplexed together, and then encoded, and placed in more code channel resource bearers than the existing standard, such as a SF-8 code channel, even lower SF code channel.
- the method for MIMO transmission of the HSPA+ system in the embodiment of the present invention can also use an encoding scheme similar to the HS-SICH in the existing specification, that is, each part of the signaling information on the HS-SICH channel is separately encoded, and then the encoding is performed. The output is multiplexed, after interleaving, adaptively selected Select the corresponding code channel resource bearer.
- the MIMO mode includes both single stream and dual stream. Since the MMO mode does not always use dual streams to transmit data, when the channel conditions are poor, in order to ensure the data transmission quality, it is necessary to switch to single stream transmission; and when the channel conditions are improved, switch to the dual stream transmission. Therefore, in the embodiment of the present invention, the signaling information included in the HS-SICH can support single stream and dual stream. Since the system works in the non-MIMO mode or the MIMO mode, it can be configured by the RRC (Radio Resource Control), that is, the high layer determines the time according to the real-time service type, the amount of user data, the channel environment, and the like.
- RRC Radio Resource Control
- the non-MIMO mode refers to an operating mode in which no MIMO technology is introduced in HSDPA
- the MIMO mode refers to an operating mode in which a MIMO technology is introduced in a TDD HSPA+ system. Therefore, according to the working mode of the current system, it can be determined whether each signaling information on the HS-SICH is a non-MIMO mode or a MIMO mode. If it is a non-MIMO mode, the same design and channel coding scheme as the prior art specification signaling can be used. The following is a detailed description of the signaling design and channel coding scheme in the embodiment of the present invention in the case of the MIMO mode.
- Step 101 A UE determines, according to the number of received downlink traffic channel data streams, each of the HS-SICHs.
- the HS-SICH carries the single stream signaling; if it is a dual stream, the HS-SICH carries the dual stream signaling; Step 102; Multiple signaling is multiplexed, that is, ACK, RMF, RTBS and other signaling on the HS-SICH are multiplexed; it should be noted that different signaling flows are different in lengths of single signaling and dual-streaming, so different data flows The total length of signaling on the HS-SICH is also different; Step 103, performing verification; Cyclic Redundancy Code (CRC) can be used for verification. The CRC check can help the block error statistics and be used to assist the outer loop power control. In addition, the CRC can be used to perform the XOR of the UE identifier. Test
- each part of the signaling information on the HS-SICH channel is multiplexed together, then coded, and placed on more code channel resources than the existing standard, so that the HS-SICH channel is enabled.
- the acknowledgment of the UE's received dual stream data can be fed back, and the number of data streams in the next TTI and the transport block size and modulation mode on each data stream are recommended to the Node B.
- the Node B receives the HS-SICH, since the original signaling bit sequence lengths of the single stream and the dual stream are different, the rate matching mode is different, and there are two cases:
- the Node B can detect the HS-SICH according to the determined number of data streams, and know the number of data streams and corresponding Signaling information;
- the Node B If the Node B cannot determine that the HS-SICH fed back by the UE is for several data streams, the Node B needs to blindly detect the HS-SICH according to the single stream and the dual stream to know the number of data streams and corresponding Signaling information.
- the blind detection means that the base station decodes according to the single-stream and dual-stream HS-SICH coding modes, that is, the rate when using single-stream HS-SICH coding.
- the punctured pattern is matched for decoding, and then the rate matching puncturing pattern when using the dual stream HS-SICH encoding is used for decoding.
- the rate matching puncturing pattern in the dual stream HS-SICH encoding is also possible to first use the rate matching puncturing pattern in the dual stream HS-SICH encoding to decode, and then use the rate matching puncturing pattern in the single stream HS-SICH encoding to decode. Since only the puncturing pattern used is correct, the decoding can be correctly performed. Therefore, without knowing the number of data streams for the HS-SICH, the decoding is performed in the single stream and the dual stream respectively. If the decoding is correct, the description is correct. Which data stream is HS-SICH targeted for.
- the rate of use may be preferentially selected according to the number of data streams for which the last received HS-SICH is directed. For example, if the HS-SICH received last time is for a single stream, the rate-matched puncturing pattern for single-stream HS-SICH encoding is preferentially used for decoding, which can improve the probability of successful decoding and reduce the blind detection of Node B. The amount of work.
- the total length of the HS-SICH signaling in the MIMO mode single stream and the dual stream is different, and the Node B needs to be blindly detected to know the number of data streams and the corresponding signaling information.
- the total length of the HS-SICH signaling of the single stream and the dual stream can be set to be the same, and the Node B can be detected once.
- the UE determines each signaling on the HS-SICH according to the number of received downlink traffic channel data streams.
- the UE may also determine each signaling on the HS-SICH according to the channel condition; if the user equipment proposes to use the single-stream transmission of the next downlink traffic channel, the HS-SICH carries the signaling of the single stream; The device recommends that the next downlink traffic channel be sent in dual streams, and the HS-SICH carries dual streams.
- Step 201 A UE determines, according to the number of received downlink traffic channel data streams, each of the HS-SICHs.
- Step 202 multiplexing all the signaling, that is, multiplexing signaling such as ACK, RMF, and RTBS on the HS-SICH; It should be noted that, because the lengths of the respective signaling information required for the single stream and the silent stream are different, the total length of the signaling on the HS-SICH is different under different numbers of data streams; Step 203, setting the signaling under the dual stream The part that is more than the signaling under the single stream is the padding bit. Then, the HS-SICH signaling under the single stream is padded, and some bits are filled, so that the total length of the single stream signaling after the padding is the same as that of the dual stream.
- multiplexing signaling such as ACK, RMF, and RTBS on the HS-SICH
- Step 204 performing verification; may use Cyclic Redundancy Code (CRC) check, and performing CRC check may be helpful for error block statistics, for assisting external loop power control, and also using CRC and UE.
- Step 205 encoding the channel, for example, may use a convolutional code;
- Step 206 performing rate matching; if the length of the output sequence after channel coding is greater than the bit that can be carried by the allocated code channel resource For the length, the appropriate bit deletion can be performed.
- CRC Cyclic Redundancy Code
- Step 207 interleave
- each part of the signaling information on the HS-SICH channel is multiplexed together and then encoded, and more code channel resource bearers are placed than the existing standard, so that the HS-SICH channel can be enabled.
- the UE acknowledges the acknowledgement of the received dual stream data, and recommends to the Node B the number of data streams in the next TTI and the transport block size and modulation mode on each data stream.
- the Node B when the Node B receives the HS-SICH, since the signaling length on the HS-SICH is the same in the single stream and the dual stream, that is, the same coding rate and rate matching are adopted, the Node B only needs to detect once to obtain the HS. - Signaling information on the SICH. There are two situations: (1) If the UE feeds back the HS-SICH according to the number of downlink traffic channel data streams sent by the Node B, the Node B can detect the HS-SICH at a time according to the determined number of data streams;
- the Node B If the Node B cannot determine that the HS-SICH fed back by the UE is for several data streams, the Node B needs to perform a detection on the HS-SICH to know the number of data streams and the corresponding signaling information. At this time, the Node B can determine whether the signaling information on the HS-SICH is a single stream or a dual stream according to the bits of the padding bits. For example, the RTBS in the single stream is 6 bits, and the RTBS in the dual stream is 12 bits, then the RTBS in the single stream can be filled. 6 bits of 0, so the total length is also 12bits. After the Node B decodes the HS-SICH, it first reads the padding bits of the 6 bits. If it is all 0, it means a single-stream HS-SICH. If it is non-zero, it means a dual-stream HS-SICH. After determining the number of data streams, Node B reads each signaling information from the valid bits.
- the UE determines each signaling on the HS-SICH according to the number of received downlink traffic channel data streams.
- the UE may also determine each signaling on the HS-SICH according to the channel condition; if the user equipment proposes to use the single-stream transmission of the next downlink traffic channel, the HS-SICH carries the signaling of the single stream; The device recommends that the next downlink traffic channel be sent in dual streams, and the HS-SICH carries dual streams.

- the coding method is the same as the prior art.
- the arrangement relationship between the feedback signalings of the two streams may be arbitrary, but it must be pre-agreed, so that the Node B can match the signaling sequence used by the UE when decoding the HS-SICH, thereby obtaining the corresponding Signaling information.
- the feedback signaling on each data stream can be mapped to one SF-16 virtual code channel, so that each data is The feedback signaling of the flow is the same as the HS-SICH of the prior art single-stream downlink traffic channel.
- the arrangement relationship between the feedback signals of the two data streams may also be arbitrary, but it must be pre-agreed.
- the Node B when the Node B receives the HS-SICH, the UE feeds back the HS-SICH according to the number of downlink traffic channel data streams sent by the Node B, so the Node B knows that the HS-SICH fed back by the UE is for several data streams. . Based on this known number of data streams, Node B receives and detects the HS-SICH from the corresponding code channel resources.
- the relationship is arranged to obtain individual signaling information.
- the code channel resource carrying the HS-SICH is flexibly selected according to the number of data streams, and the coding scheme similar to the HS-SICH in the prior art is used, that is, the signaling information of each part on the HS-SICH channel is used. They are separately encoded, and the encoded outputs are multiplexed and mapped to physical channels.
- Step 400 A UE determines, according to a required number of data streams, a letter on the HS-SICH. The number of the data streams may be different from the number of data streams of the downlink traffic channel received by the UE.
- Step 411 setting the signaling under the dual stream to be more padded than the signaling under the single stream, then the single stream
- the HS-SICH signaling fills in some bits, so that the total length of the single stream signaling after the padding is the same as that of the dual stream
- Step 412 encoding the valid bits and padding bits of each signaling, and the same coding as the prior art can be used.
- the valid bit of the signaling and the padding bit may be separately coded, or the valid bit of the signaling may be encoded together with the padding bit;

- the bit length is 0, so the total length is also 12bits.
- the Node B decodes the HS-SICH, it first reads the padding bits of the 6 bits. If it is all 0, it means that it is a single-stream HS-SICH. If it is not 0, it means a dual-stream HS-SICH.

- the interleaving unit 704 is configured to output the multiplexed coded sequence that is read in a specific order according to a specified interleaving pattern
- Mapping unit 705 is configured to map the output of the multiplexing unit to the determined code resource carrying the HS-SICH.
- the determining unit 701 flexibly selects the code channel resource carrying the HS-SICH according to the number of data streams, and may adopt an encoding scheme similar to the HS-SICH in the prior art, that is, the HS- The signaling information of each part on the SICH channel is separately encoded, and the encoded output is multiplexed and mapped to the physical channel. Thereby, the HS-SICH channel can be fed back to the UE for confirming the received dual stream data, and the Node B is recommended for the number of data streams in the next TTI and the transport block size and modulation mode on each data stream.
- the HS-SICH signaling encoded by the encoding unit 702 is unequal in single stream and dual stream. Since no CRC face exists, the Node B cannot use the blind detection to learn the HS-SICH. The number of data streams targeted. Therefore, in this embodiment, the number of data streams required by the HS-SICH is equal to the number of downlink traffic channel data streams received by the user equipment.
- FIG. 8 is a schematic structural diagram of a fourth embodiment of a user equipment according to an embodiment of the present invention.
- the user equipment includes the corresponding unit in FIG.
- a filling unit 806 is further included between the determining unit 801 and the encoding unit 802 for multiplexing the single stream.
- the HS-SICH signaling performs bit stuffing.
- the HS-SICH signaling input by the encoding unit 802 can be made equal in single stream and dual stream.
- the Node B when receiving the HS-SICH, the Node B can determine whether the signaling information on the HS-SICH is single-stream or dual according to the bits of the padding bits.
- the stream after determining the number of data streams, can read each signaling information from the valid bits.
