Description

Uplink feedback method, user equipment and base station

Embodiments of the present invention relate to the field of wireless communications, and more particularly, to an uplink feedback method, a user equipment, and a base station. Background technique

Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS) is the International Organization for Standardization Third Generation Partnership Project ^{(3 rf Generation Partnership Project, 3GPP} ) one of the world's 3G standards. Prior to UMTS Release-5, Wideband Code Division Multiple Access (WDCMA) was one of the mainstream technologies for third-generation mobile communication systems. The High Speed Downlink Packet Access (HSDPA) technology was introduced in the Release-5 version to improve the downlink data transmission rate and reduce the user data transmission delay, so that users can have better in the UMTS network. Experience.

The channels involved in HSDPA include a High-Speed Physical Downlink Shared Channel (HS-PDSCH), a High-Speed Shared Control Channel (HS-SCCH), and an uplink high-speed. Uplink High-Speed Dedicated Physical Control Channel (HS-DPCCH).

The physical layer of the HSDPA technology works as follows: The base station (NodeB) sends data to the user equipment (UE) through the HS-PDSCH of the physical layer, and sends control signaling corresponding to the HS-PDSCH through the HS-SCCH. After receiving the HS-SCCH, the UE demodulates, decodes, etc. the HS-PDSCH by using the control information carried thereon. Then, the UE generates ACK (Acknowledgement) / NACK (Non-Acknowledgement) / DTX (no transmission) information according to the HS-SCCH reception condition and whether the HS-PDSCH is decoded correctly. In addition, the UE also measures the downlink channel status, generates channel quality indicator (CQI) information, and then the UE carries the ACK/NACK/DTX information and the CQI information on the HS-DPCCH channel, and sends the information to the NodeB. The NodeB uses the feedback information of the UE as the basis for the service scheduling.

The above feedback information is carried on the uplink HS-DPCCH channel. HS-DPCCH frame knot The frame is 10 ms for each radio frame; and each radio frame includes 5 subframes, each subframe is 2 ms; - each subframe is divided into 3 slots, and each slot is 2560 chips. The first time slot of the three time slots performs HARQ (Hybird Automatic Repeat Request) feedback, and the remaining two time slots are used for feedback CQI and Precoding Control Indication (PCI). On the user equipment (UE) side, the timing relationship between the HS-DPCCH and the HS-PDSCH is: corresponding to the HS-DPCCH subframe corresponding to the 7.5 time slot (5ms) after the UE receives the HS-PDSCH subframe. HS-DPCCH feedback information.

With the evolution of the protocol version, dual-carrier/cell high-speed downlink packet access (Dual Carrier/Cell HSDPA, DC HSDPA) is introduced in Rel-8/9/lO, and dual-carrier/cell multiple input is introduced. Output High-Speed Input Multiple Output HSDPA (DC-MIMO HSDPA), and 4C HSDPA technology, 8C HSDPA technology. Correspondingly, a new HS-DPCCH frame structure has been introduced with a spreading factor of 128. The main difference from SF256 is that the symbol/bit rate is doubled and can carry twice as much information.

In the DC HSPDA technology, including one primary carrier and one secondary carrier, the HARQ feedback information in the HS-DPCCH feedback information is jointly coded by 10 bits, and the coding manner is as shown in Table 1: Table 1 HARQ feedback information under dual carrier non-MIMO Channel coding format

Correspondingly, the bits corresponding to the CQI in the HS-DPCCH feedback information are directly generated by the respective CQI connections of the two carriers, that is, each CQI is represented by 5 bits. It is then encoded (20, 10) into the last two slots of the HS-DPCCH subframe. In the DC-MIMO HSPDA technology, one primary carrier and one secondary carrier are included. The HARQ feedback information in the HS-DPCCH feedback information is still in 10-bit joint coding mode, as shown in Table 2 below, where A represents ACK, N represents NACK, D represents DTX, and AA, AN, NA, and NN represent primary and secondary carriers, respectively. HARQ feedback.

Table 2 Encoding format of HARQ feedback information under dual carrier + MIMO

Accordingly, the CQI/PCI in the HS-DPCCH feedback information is transmitted in time division. The first subframe transmits the CQI/PCI of the primary carrier, and the second subframe transmits the CQI/PCI of the secondary carrier, as shown in Table 3:

Feedback feedback feedback

In the three-carrier non-MIMO HSPDA technology, one primary carrier and two secondary carriers are included. The HARQ feedback information in the HS-DPCCH feedback information is still in 10-bit joint coding, as shown in Table 4:

Table 4 Encoding format of HARQ feedback information under three-carrier non-MIMO

Correspondingly, the CQI in the HS-DPCCH feedback information is distributed on time, the first subframe transmits the CQI of the primary carrier, and the second subframe transmits the CQI of the first secondary carrier and the second secondary carrier.

In the 4C HSDPA technology, a primary carrier and three secondary carriers are included. HS-DPCCH uses spread spectrum The Spreading Factor (SF) 128, so that the HS-DPCCH can carry twice as much information as the SF256. The HARQ feedback information of the downlink 4 carriers is still placed in the first slot of the HS-DPCCH subframe. The four carriers are divided into two groups, and each group of two carriers performs joint coding defined by Rel-9, and the encoded sequences are respectively carried in the first half slot and the second half slot of the first slot. The information fields of HS-DPCCH are shown in Table 5:

Table 5: HS-DPCCH Information Fields Under Four Carriers

The multi-carrier can be used to improve the data throughput of the cell edge UE and the peak rate of the UE, wherein each carrier bandwidth is 5M. Currently, a new variable bandwidth multi-carrier Universal Mobile Telecommunication System (UMTS) is proposed. Wherein, the bandwidth of each carrier is variable, and the carrier frequency of different bandwidths can be configured. When a carrier of less than 5M bandwidth (called S-UMTS) is used, the operation of the physical layer and the existing UMTS are achieved, and only the system clock is reduced to achieve smaller bandwidth transmission, and the existing hardware is also not changed as much as possible. Taking dual carriers as an example, the bandwidth of carrier 1 is 5M, and the bandwidth of carrier 2 is 2.5M. In carrier 1, one radio frame is 10 ms, which is divided into 5 subframes, that is, 2 ms for each subframe, and 3 subframes for one subframe; and in carrier 2, one radio frame is 20 ms, which is also divided into 5 subframes. That is, 4 ms per subframe, 3 subframes for one subframe. By analogy, a frame structure of 1/4 S-UMTS, 1/8 S-UMTS can be obtained.

In the variable bandwidth multi-carrier UMTS, in the same configuration, the chip rate of 1/2 S-UMTS is slow, which is half of the normal UMTS chip rate, and the corresponding uplink feedback frequency is also half of the normal UMTS. In the variable bandwidth multi-carrier UMTS, the uplink feedback mode of the UE needs to be further solved. Summary of the invention

Determine HS-DPCCH feedback information of each HS-PDSCH subframe in the HS-PDSCH of each carrier, and determine a first HS-DPCCH corresponding to the HS-PDSCH from the K HS-DPCCHs of the UE, where The bandwidth of the carrier where the HS-PDSCH is located is 1/N of the standard carrier bandwidth of the UMTS, M is a positive integer greater than 1, and N and K are positive integers, and the bandwidth of at least one of the M carriers is not equal to the standard carrier bandwidth. .

102. Determine, according to the timing relationship between the N and the HS-PDSCH and the first HS-DPCCH, the P HS-DPCCH subframes occupied by the HS-DPCCH feedback information, where P is a positive integer.

103. Send HS-DPCCH feedback information to the base station on the P HS-DPCCH subframes. In the embodiment of the present invention, the uplink feedback problem of the variable bandwidth multi-carrier is solved by configuring the correspondence between the feedback information of the HS-PDSCH subframe of the variable bandwidth multi-carrier and the HS-DPCCH subframe.

It should be understood that the embodiment of FIG. 1 provides an uplink feedback method for each of the M carriers, and is not intended to limit the method to only one execution. For example, when the UE receives downlink data information of two carriers, the data information of each carrier may be separately fed back according to the method of FIG. Optionally, as an embodiment, the HS-DPCCH feedback information may include first feedback information and second feedback information, where the first feedback information may be HARQ feedback information, the second feedback information may be CQI, and the second feedback information may also be It is CQI and PCI.

The above HARQ feedback information may be one of ACK, NACK, and DTX. Corresponding to each HS-PDSCH subframe used for transmitting downlink data information, the HARQ feedback information is used to indicate the reception of uplink and downlink data information of each HS-PDSCH subframe. The CQI is used to indicate the channel quality of the carrier. If the carrier is configured with MIMO, the second feedback information may further include PCI.

It should be noted that, in the embodiment of the present invention, the manner of determining the first HS-DPCCH corresponding to the HS-PDSCH from the K HS-DPCCHs of the UE in step 101 is not limited.

Optionally, as another embodiment, the K value may be equal to the number of different carrier bandwidths included in the M carriers, and determining the first HS-DPCCH corresponding to the HS-PDSCH from the K HS-DPCCHs of the UE may include Determining a carrier bandwidth of a carrier where each HS-DPCCH is located in the K HS-DPCCH and a first carrier bandwidth of a carrier where the HS-PDSCH is located; determining a first HS-DPCCH, a carrier bandwidth of the carrier where the first HS-DPCCH is located, and the first The carrier bandwidth has the same carrier bandwidth.

For example, M=4, the carrier bandwidth of the 1st and 2nd carriers in the 4 carriers is 5M, and the carrier bandwidth of the 3rd and 4th carriers is 2.5M, then K=2. At this time, in the two HS-DPCCHs of the UE, the carrier bandwidth of the uplink carrier where the first HS-DPCCH is located is 5M, and the carrier bandwidth of the uplink carrier where the second HS-DPCCH is located is 2.5M. Therefore, the first HS-DPCCH feeds back the downlink data information of the first and second carriers, and the second HS-DPCCH feeds back the downlink data information of the 3 and 4 carriers.

Optionally, M=2, the carrier bandwidth of the two carriers is 2.5M, then K=l. At this time, the HS-PDSCH of the two carriers is fed back on the HS-DPCCH of the uplink carrier with a bandwidth of 2.5M.

Optionally, as another embodiment, the carriers where the K HS-DPCCHs are located have the same carrier bandwidth, and P is equal to N. For example, M=3, the carrier bandwidth of the first carrier of the three carriers is 5M, the second carrier is 2.5M, and the third carrier is 1.25M. The UE only provides one HS-DPCCH, and the uplink carrier bandwidth of the HS-DPCCH is 5M. Then, the HS-PDSCH of the three carriers is fed back on the HS-DPCCH.

In addition, when the standard bandwidth of the UMTS is 5M and the N value of the first carrier is 1, the feedback information of each HS-PDSCH subframe of the first carrier occupies 1 subframe on the HS-DPCCH; likewise, the second carrier The value of N is 2, occupying 2 subframes on the HS-DPCCH; likewise, the N value of the 3rd carrier is 4, and 4 subframes are occupied on the HS-DPCCH. It should be noted that determining the occupation in the P HS-DPCCH subframes occupied by the HS-DPCCH feedback information in step 102 is a logical concept, and the HS-DPCCH feedback information may use all P HS-DPCCHs. For a subframe, one of P HS-DPCCH subframes may also be used, and any one of P HS-DPCCH subframes may also be used. In addition, the first feedback information and the second feedback information in the feedback information may also occupy the same subframe or different subframes in the P-HS-DPCCH subframes, which is not limited in this embodiment of the present invention.

Optionally, as another embodiment, the sending the HS-DPCCH feedback information to the base station on the P HS-DPCCH subframes may include: sending the base station to each of the HS-DPCCH subframes of the P HS-DPCCH subframes. Send the first feedback message. It should be noted that, in the embodiment of the present invention, the subframe in which the second feedback information of the HS-DPCCH is located is not limited.

Optionally, as another embodiment, the second feedback information may be sent to the base station on each HS-DPCCH subframe of the P HS-DPCCH subframes.

Optionally, as another embodiment, the second feedback information may be sent to the base station on the P1 HS-DPCCH subframes in the P HS-DPCCH subframes, where P1 is 1/2 of P.

Optionally, as another embodiment, the sending the HS-DPCCH feedback information to the base station on the P HS-DPCCH subframes may include: sending, to the base station, an HS-DPCCH subframe of the P HS-DPCCH subframes. First feedback information. It should be noted that, in the embodiment of the present invention, the subframe in which the second feedback information of the HS-DPCCH is located is not limited.

Optionally, as another embodiment, one of the P HS-DPCCH subframes may be

The second feedback information is sent to the base station on the HS-DPCCH subframe. Optionally, the second feedback information of the HS-DPCCH may also be sent to the base station on each of the HS-DPCCH subframes of the P HS-DPCCH subframes.

It should be noted that the P HS-DPCCH subframes occupied by the HS-DPCCH feedback information may also be occupied by other HS-DPCCH feedback information. The embodiment of the present invention does not limit the specific form in which multiple HS-DPCCH feedback information occupies the same HS-DPCCH subframe. For example, if the HARQ feedback information of the two HS-DPCCH feedback information occupies the slot 0 of the subframe of the same HS-DPCCH, then the two HARQ feedback information can be jointly encoded; for example, the four HS-DPCCH feedback information The HARQ feedback information occupies the slot 0 of the subframe of the same HS-DPCCH, and the two HARQ feedback information of the four HARQ feedback information may be carried in the first half of the slot 0, and the remaining two HARQ feedback information Beared in the second half of time slot 0 The slot, and jointly encodes two HARQ feedback information in each half slot.
