Description

Resource mapping method and detector for feedback information

The present invention relates to the field of wireless communications, and in particular, to a resource mapping method, a detection method, an apparatus, and a system for feedback information. Background technique

In order to improve the reliability of correct decoding of erroneous data blocks, Hybrid Automatic Repeat Request (HA Q) is often used in wireless communication systems. HARQ is implemented by combining ARQ (Automatic Repeat Request) technology with Forward Error Correction (FEC) technology. At the receiving end, the Cyclic Redundancy Check (CRC) is first used to determine whether the data block is correctly received. If an error is found, an ARQ is performed to request retransmission of data. In the LTE (Long Term Evolution) and LTE-Advanced (Enhanced Long Term Evolution) uplink systems, the HARQ technology is adopted. The base station (NB or eNB) detects the CRC. If an error is found, the user terminal (UE, User Equipment, user equipment, or simply user or terminal) sends a retransmission request. After receiving the request, the user equipment retransmits the data block to the base station.

The PHICH (Physical HARQ Indicator Channel) channel is used to carry the ACK (Acknowledgement)/NACK (Negative Acknowledgement) information sent by the base station to the user in the LTE and LTE-Advanced systems. To support synchronous non-adaptive retransmissions. Assuming that the user transmits a PUSCH (Physical Uplink Shared Channel) at time n, the base station will transmit the PHICH at a fixed n+k time. In the FDD (Frequency Division Duplexing) system, k is fixed to 4, In a TDD (Time Division Duplexing) system, k may take different values depending on the TDD uplink and downlink configuration, but the value is a pre-fixed value known to both the user and the base station. After receiving the NACK, the user will retransmit on the same physical resource in the same way as the last transmission at the time of n+k+kl, and the user will not send it after receiving the ACK.

The PHICH channels of different users can be mapped to the same downlink physical resource element (RE). A PHICH channel is mapped to a PHICH resource group (PHICH group for short), and is determined by an orthogonal complex Walsh sequence in the PHICH group, that is, each PHICH channel is uniquely determined by the PHICH group number ^ and the sequence number. , as shown in equation (1). ⁿ PHICH = ^PRB RA + ⁿ DMRS ) ^{mod N} PHICH + ¹ PHICH ^N PHICI

At present, for the FDD system, the design of the PHICH only considers the case where one DCI schedules a PUSCH of one subframe, and for the TDD system, except for the uplink and downlink configuration 0, the design of the PHICH only considers one DCI to schedule a PUSCH of one subframe. Case. For the uplink and downlink configuration 0 of the TDD system, the design of the PHICH considers the case where one DCI schedules the PUSCH of two subframes, and the PHICH resource corresponding to the PUSCH of the second subframe and the PUSCH of the first subframe correspond to the PHICH resource completely. There is no overlap, that is, the PHICH resource is twice as large as other cases.

In the process of implementing the present invention, the inventor has found that in a new network deployment scenario, such as a small base station scenario, one control signaling scheduling transmission of multiple data channels is an effective way to save control signaling overhead. However, when scheduling transmission of multiple data channels through one control signaling, how to avoid resource collisions and excessively redundant resources to improve channel efficiency is an urgent subject in the art.

The foregoing and other features of the embodiments of the invention will be apparent from the These embodiments are merely exemplary and are not limiting of the invention.

In the process of implementing the present invention, the inventor has found that in a new network deployment scenario, such as a small base station scenario, one control signaling scheduling transmission of multiple data channels is an effective way to save control signaling overhead. For example, one DCI can schedule PDSCH/PUSCH transmission of multiple subframes, or one DCI can schedule PDSCH/PUSCH transmission of multiple base stations. Then, if the ACK/NACK of the scheduled multiple data channels is fed back in the same subframe, how to design a feedback channel carrying ACK/NACK of multiple data channels to avoid ACK/NACK resources of PUSCH in different subframes Collision is a problem worth studying.

In order to enable the person skilled in the art to easily understand the principles and embodiments of the present invention, the foregoing embodiment of the present invention is a PUSCH, and a physical channel for carrying ACK/NACK is a PHICH. The resource mapping method and apparatus for the feedback information are described, but it should be understood that the embodiment of the present invention is not limited thereto. For example, the physical channel used for carrying the ACK/NACK may also be another physical medium that can carry the ACK/NACK of the PUSCH. Channels, such as ePHICH, ePDCCH, etc., therefore, the methods and apparatus provided by the embodiments of the present invention are applicable to other scenarios involving resource mapping of feedback information.

The specific embodiments of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Example 1

The embodiment of the invention provides a resource mapping method for feedback information. Figure 1 is a flow chart of the method, please refer to Figure 1, the method includes:

Step 101: Determine, according to the uplink data signal sent by the sending end in different subframes, resources occupied by the feedback information of the uplink data signal sent in each subframe, where the feedback of the uplink data signal sent in different subframes The resources used by the information are different;

Step 102: Map resources occupied by the feedback information to objects carrying feedback information in the same subframe. On the physical channel, the feedback information of the uplink data signals transmitted in different subframes is transmitted through the physical channel.

The feedback information may be a positive acknowledgment information ACK, or may be a qualitative acknowledgment information NACK, depending on whether the uplink data signal is correctly received. For example, if the uplink data signal sent in a certain subframe is correctly received, the corresponding feedback information is ACK, and if the uplink data signal sent in a certain subframe is not correctly received, the corresponding feedback information is received. For NACK.

The physical channel carrying the feedback information may be a PHICH, an ePHICH, an ePDCCH, or the like.

In this embodiment, the feedback information of the uplink data signal sent in different subframes is sent by the physical channel carrying the feedback information, and the resources occupied by the feedback information of the uplink data signal sent in different subframes are different. The problem of resource collision when these feedback information is sent in the same subframe is avoided.

In the embodiment of the present invention, the resources occupied by the feedback information of the uplink data signal sent in each subframe may be determined by various means, as long as the feedback information of the uplink data signal sent in different subframes is ensured. The occupied resources are different, and some preferred embodiments are listed below, but the invention is not limited thereto.

Example 2

The embodiment of the present invention further provides a resource mapping method for feedback information, and FIG. 1 is a flowchart of the method. In this embodiment, resources used by the feedback information of the uplink data signal sent in each subframe are determined ( Step 101) can be implemented by the method shown in FIG. 2. Referring to FIG. 2, the method includes:

Step 201: Determine, for each subframe in which the uplink data is sent, a cyclic shift sequence number of the pilot signal of the uplink data according to downlink control information for scheduling the uplink data, where the pilot signal of the uplink data of each subframe is The cyclic displacement numbers are different;

Step 202: Determine, according to the cyclic shift sequence number and the first channel indication information, resources occupied by feedback information of the uplink data signal sent in each subframe.

In step 201, the downlink control information is used to schedule the sending of the uplink data signal sent by the sending end in different subframes, and in the embodiment, the downlink control information indicates at least one of the subframes. The cyclic shift of the pilot signal, whereby the cyclic shift of each subframe can be determined according to the cyclic shift of the pilot signal of the subframe indicated by the downlink control information; thereby, the cyclic shift sequence number of each subframe can be determined.

In this embodiment, the CS (cyclic shift) used by the DM-RS of each subframe is different. At this time, according to the CS of one of the subframes indicated by the downlink control information, other subframes are determined according to a predetermined policy. of CS, where the CS of the other subframe is different from the CS of the subframe indicated by the downlink control information.

This is illustrated by way of example below.

When the base station transmits the PUSCH (uplink data signal) in the n+4, n+5..., n+2+N, n+3+N subframe by DCI (downlink control information) in the nth subframe, The M bits in the DCI are used to indicate a DM-RS (pilot signal) resource of one of the N subframes, for example, a cyclic shift (CS) indicating a DM-RS in an n+3+N subframe. For the ring lj, the cyclic shift of the DM-RS in the n+2+N, n+1+N,..., n+4 sub-frame can be according to the formula = _s +^ modl2, e {0, l,. .., N-1} is calculated. Where, according to the

V N )

The formula determines the CS of the DM-RS of the other subframes. For example, the embodiment does not limit this. In other implementations, the CS of the DMRS of other subframes may be determined according to other policies. 0 FIG. 3A is a schematic diagram of scheduling of an uplink data signal when N=4, and FIG. 3B is a schematic structural diagram of downlink control information, as shown in FIG. 3A and FIG. 3B. N=4, if the DM-RS W« _c = 3 in the n+7 subframe is indicated, according to the above formula, the DM-RS in the n+6, n+5, n+4 subframes are respectively 0. , 9, 6. When using the ACK / NACK feedback PHICH carries the PUSCH, the formula (1), n + 4, n + 5, n + 6, n + 7 subframe for the PUSCH ACK / NACK corresponding to the PHICH resource ^ _5, respectively Is 6, 9, 0, 3. Thus, the base station can transmit the PHICH in n+11 subframes.

In step 202, when the cyclic shift sequence number of each subframe is obtained, it may be determined in each subframe according to the cyclic shift sequence number and other channel indication information (referred to as first channel indication information in this embodiment). The resources occupied by the feedback information of the transmitted uplink data signal.

In an embodiment, the first channel indication information may include a number of time-frequency resource groups (N _H ) of the feedback channel carrying the feedback information and an index number of the physical resource block occupied by the uplink data signal (I _PRB — RA) For each subframe in which the uplink data signal is transmitted, the resources occupied by the feedback information of the uplink data signal transmitted in the subframe may be calculated by the following formula:

Wherein, the calculation is obtained by the step 201 of the embodiment, and the meanings of the other parameters have been described in detail in the background section, and the contents thereof are incorporated herein, and are not described herein again.

In another embodiment, the first channel indication information may include subframe number indication information of the subframe in addition to the foregoing and I _PRB — _RA . Determining the feedback of the uplink data signal transmitted in each subframe by using the subframe number indication information and the n _DMRS of each subframe obtained in step 201, and other parameters as described above The resources used by the information. The subframe number indication information may be a sequence number of the subframe or may be twice the sequence number of the subframe.

The resources occupied by the feedback information of the uplink data signal sent in each subframe may be represented by formula (2):

^ACKiNACK- f (j , ⁿ DMRS, ^PRB RA ) ( 2 ) can also be expressed by the formula (3):

^ ACKiNACK - f simplification (^i, ⁿ DMRS, ^PRB RA ) (3) where i is the subframe number in the above-mentioned subframe number indication information, and n _DMRS is obtained by the calculation in step 201 of this embodiment.

When the resources occupied by the feedback information of the uplink data signal sent in each subframe are determined according to the formula (3), resources occupied by the feedback information of different transport blocks of the uplink data signals of different subframes can be simultaneously avoided. No collisions occur. That is, the first transport block in the i-th subframe cannot be adjacent to the ACK/NACK resource of the first transport block in the i+1 (or i-1) subframes to avoid the i+1 ( Or the ACK/NACK resource of the 1st transport block in the i-1 subframes collides with the ACK/NACK resource of the 2nd transport block in the i-th subframe.

In this embodiment, optionally, the resources occupied by the feedback information of the uplink data signal sent by the sending end in different subframes are in the same group of physical resources of the physical channel carrying the feedback information. The same set of physical resources here may be the same downlink control information used to carry feedback information, or may be the same set of time-frequency resources.

For example, if the DCI similar to the existing DCI format 3/3 A is used to carry ACK/NACK of multiple PUSCHs, the ACK/NACK of the PUSCH of different subframes scheduled by the same scheduling information cannot be dispersed in different DCIs. It should be kept in the same DCI.

In the foregoing two embodiments, the number of time-frequency resource groups of the feedback channel carrying the feedback information may be The value of the pre-configured parameter ranges from less than 1/6, for example, 1 /12, 1/16, etc., and the number of time-frequency resource groups is less than 3.

Taking PHICH as an example, the number of PHICH time-frequency resource groups can be determined according to formula (4):

In this embodiment, the value ranges from 1/6, 1/2, 1, 2, in addition, you can also increase the range of values less than 1 / 6, such as = 1 / 12, = 1 / 16, etc., as shown in Table 1, thereby reducing the number of ^, in the case of large bandwidth, Can improve resource utilization.

Table 1

The resource occupied by the feedback information of the uplink data signal sent in each subframe is determined by the method in this embodiment, and is mapped to the corresponding physical channel carrying the feedback information, thereby improving resource utilization and avoiding resource waste. At the same time, the problem of resource collision when these feedback information is sent in the same subframe is avoided.

In this embodiment, the resources occupied by the feedback information of the uplink data signal sent in each subframe are determined. It can be implemented by the method shown in FIG. 4. Referring to FIG. 4, the method includes:

Step 401: Obtain subframe number indication information of the subframe for each subframe in which uplink data is sent. Step 402: Determine, according to the subframe sequence indication information and the second channel indication information, the identifier sent in the subframe.
