Description

SRS (sounding reference Signal) and PUCCH (physical uplink control channel) coordinated transmission method and system

Technical Field

The present invention relates to the field of communications, and in particular, to a method and a system for coordinated transmission of a Sounding Reference Signal (SRS) and a Physical Uplink Control Channel (PUCCH).

Background

With the increasing demand of people for future communication, the spectrum efficiency at the edge of a cell is more emphasized, and how to improve the transmission quality and throughput at the edge of the cell becomes a competitive research topic. The coordinated multi-point transmission technology utilizes the coordinated transmission of a plurality of cell transmitting antennas, and can effectively solve the problem of interference at the edge of a cell, thereby improving the capacity and reliability of a wireless link. Therefore, a coordinated Multi-Point (CoMP) technology is introduced into the LTE-a system as a key technology.

In CoMP, a cell that transmits downlink control information or receives uplink control information is called a serving cell (ServingCell), and the remaining cells are called cooperative cells. In the UE under CoMP, the uplink transmission signal of the UE reaches the receiving end of each cooperating cell, so that there is strong mutual interference between each physical channel of the CoMP UE and each physical channel of other UEs in the cell at the uplink receiving end of the cooperating cell, which affects the receiving performance. Interference between a Physical Uplink Shared Channel (PUSCH) and a PUSCH can be cancelled by coordinated scheduling or joint reception; some prior arts provide methods and systems for coordinated transmission or interference cancellation of SRS and SRS, PUCCH and PUCCH, and Physical Random Access Channel (PRACH) and PRACH among users of different cells in CoMP.

Similarly, mutual interference exists between SRS and PUCCH between different cell users in CoMP. As shown in fig. 1, assume that a user equipment (UE — 11) is in CoMP mode; cell _1 is its serving Cell (UE _11 sends control information to or receives control information from this Cell); cell _2, Cell _ 3. Since the UE _11 is in the CoMP mode, the UE _11 sends a signal to the Cell _2, the Cell _3, the. However, in the related art, there is no method for eliminating mutual interference between SRS and PUCCH between users in different cells in CoMP.

In view of the above problems in the related art, no effective solution has been proposed at present.

Preferred embodiment 1

In view of the above problems, the present embodiment provides a method for coordinated transmission of SRS and PUCCH between different cells in CoMP, which reduces mutual interference between SRS and PUCCH of different cells in a coordinated set, and improves SRS measurement accuracy and PUCCH performance.

In this example, based on the typical scenario of mutual interference between SRS and PUCCH shown in fig. 1, the scenario is as follows:

scene one: in a subframe (subframe), UE _11 transmits SRS, Cell _2, Cell _3,.. and UE in Cell _ N transmits PUCCH, and the subcarriers occupied by the two UEs overlap. At this time, on the one hand, PUCCH of Cell _ N affects measurement accuracy of UE _11 SRS; on the other hand, SRS transmitted by UE _11 also affects demodulation performance of Cell _2, Cell _ 3.

Scene two: for a subframe, UE _11 transmits PUCCH, Cell _2, Cell _3,. and UEs in Cell _ N transmit SRS, and subcarriers occupied by the two UEs overlap. At this time, the PUCCH mainly transmitted by UE _11 affects the measurement accuracy of SRS in each cooperative Cell _2, Cell _ 3.

Note that although the following method description is exemplified by the above assumption, for other scenarios, such as Cell _1, Cell _2, and Cell _ N, where there are UEs in CoMP and there are common cooperating cells, the following method may be used iteratively between different cells, or a centralized controller may be used. Another notable problem is: in the following description, if information needs to be exchanged between the serving cell and each cooperating cell, and the serving cell and each cooperating cell are located in different enodebs, the information needs to be transmitted through X2.

In the following embodiments, if information needs to be exchanged between Cell _1 and Cell _2, Cell _3, and Cell _ N are located in different enodebs, the information may need to be transmitted through an X2 or S1 interface.

step 101: cell _2, Cell _ 3.. said., Cell _ N calculates the Resource Block (RB) that each Cell PUCCH1/1a/1b may use, the maximum index value in the low frequency part

Step 102: cell _2, Cell _3, will be of each Cell

And is sent to Cell _ 1.

Step 103: when UE _11 enters CoMP mode, Cell _1 allocates periodic and/or aperiodic SRS resources for it and guarantees that the allocated SRS resources and the largest frequency domain resources that Cell _2, Cell _ 3.

Step 104: and the Cell Cell _1 sends the SRS configuration information to the UE _11 through an air interface.

Step 105: and the UE _11 transmits the SRS according to the SRS configuration information. Meanwhile, when the UE in the Cell _ N transmits PUCCH (1/1a/1b or 2/2a/2b), the UE is not influenced by CoMP and transmits according to the configuration mode of the Cell.

The examples at this point are as follows:

step 201: cell _2, Cell _ 3.. to.. Cell _ N calculates the maximum value N of frequency domain resources that may be used by each Cell PUCCH, N_PRB. Feasible N_PRBThe calculation method is as follows: if the local cell allows the ACK/NACK/SR and the SRS to be transmitted in the same subframe, N is_PRBThe maximum index value of a Resource Block (RB) in a low frequency part, which is possibly used by the PUCCH2/2a/2b of the cell; otherwise, N_PRBThe maximum index value of the RB in the low frequency part possibly used by the PUCCH1/1a/1b of the cell.

Step 202: cell _2, Cell _3,.. the Cell _ N will have its own parameter N_PRBAnd is sent to Cell _ 1. Meanwhile, Cell _1 sends the SRS Cell level subframe set configuration of the Cell to Cell _2, Cell _3, · and Cell _ N; or Cell _1 divides a subframe set used by the SRS of the CoMP UE for the CoMP UE, wherein the set may or may not be a subset of the SRS Cell-level subframe set of the Cell, and sends the SRS subframe set of the CoMP UE to the cooperating Cell. One possible definition method of the above separately partitioned CoMP UE SRS subframe set is as follows: the set is a subset of the SRS cell-level subframe set of the cell and is defined in the LTE-a existing standard TS 36.211.

If each cooperative Cell Cell _2, Cell _3,.. said., the UE of Cell _ N has PUCCH2/2a/2b to transmit, the UE normally transmits according to the configuration mode of the Cell. Meanwhile, when the Cell Cell _1 has SRS transmission, the SRS is normally transmitted according to the configuration mode of the Cell.

Example 4

And each cooperative cell coordinates and configures SRS frequency domain resources of the cell, and actively avoids interference possibly caused by PUCCH transmission of the serving cell. The specific examples at this time are:

step 301: the serving Cell Cell _1 calculates the maximum index value of Resource Blocks (RBs) which may be used by the PUCCH1/1a/1b of the Cell in the low frequency part

Step 302: serving Cell Cell _1 compares the own Cell parameters

And sending the information to each cooperative Cell Cell _2, Cell _ 3.

Step 303: when a UE accesses a Cell _ N in a Cell _ i { Cell _2, Cell _ 3.. 9.. the Cell _ N }, the Cell _ i allocates periodic and/or aperiodic SRS resources for the UE of the Cell and ensures the allocated SRS resources and PUCCH resources of the Cell _1

Do not overlap in the frequency domain.

Step 304: and the Cell Cell _ i sends the SRS resource configuration information to the Cell UE through an air interface.

Step 305: and the UE of the cell sends the SRS according to the configuration.

Example 5

step 401: cell _2, Cell _3, and. One possible encoding manner of the above information is to adopt a definition manner of SRS configuration information in the existing LTE-a standard TS 36.211: with C_SRSIndicating the frequency domain bandwidth configuration and subframe configuration with srs-subframe config.

Step 402: and the Cell Cell _1 combines the SRS subframe sets of the Cell and each cooperative Cell to obtain a collection. One possible indication of this set is: srs-subframe config of LTE-A existing standard TS36.211 is adopted, so that the subframe set indicated by srs-subframe config contains the union of cells.

Step 403: when the UE _11 enters the CoMP mode, the Cell Cell _1 allocates resources for the PUCCH2/2a/2b and ensures that the allocated PUCCH2/2a/2b frequency domain resources and the frequency domain resources of the SRS of the Cell Cell _2, Cell _ 3.. the frequency domain resources of the SRS of the Cell _ N do not overlap; or that there is no collision between the allocated PUCCH2/2a/2b time domain resources and the SRS time domain resources of Cell _2, Cell _ 3.

Step 404: and the Cell Cell _1 sends the PUCCH configuration information and the SRS subframe set information to the UE _11 through an air interface.

Step 405: when the UE _11 has PUCCH2/2a/2b for transmission, the PUCCH2/2a/2b is transmitted according to the configuration information; when UE _11 has PUCCH1/1a/1b to transmit, UE _11 judges whether the current subframe has SRS transmission according to the SRS subframe set, if so, the PUCCH1/1a/1b is transmitted by adopting a PUCCH1/1a/1b truncated format, otherwise, the current subframe is normally transmitted by adopting a PUCCH1/1a/1b normal format.
