example 1

[0114] In this example, there are three codewords / transmission blocks (groups) on the transmission side that need to be transmitted. According to the method listed in this invention, as Figure 7 The three codewords / transport blocks (groups) shown can be divided into two codeword / transport block groups, where the first group contains two codewords / transport block (groups) and the second contains a codeword / transport block (group). Words / transport blocks (groups), codewords / transport blocks (groups) belonging to the same group use the same resource configuration.

[0115] Optionally, the three codewords / transport block (groups) can be divided into one, three codeword / transport block groups.

[0116] Optionally, the obtained codeword / transport block group can be transmitted by one or more TPs.

[0117] For each codeword / transport block group, such as Figure 7 As shown, the first signaling consists of 3 Bits are used to represent the group number of the resource allocation m...

example 2

[0139] In this example, there are two codewords / transmission blocks (groups) to be transmitted on the transmission side. According to the method listed in this invention, as Figure 7 The two codewords / transport block (groups) shown are divided into two codeword / transport block groups and are transmitted by a separate transmission node from each codeword / transport block group.

[0140] By agreement, the figure 1 The resource allocation methods shown in are divided into two groups according to whether there is partial overlap: complete overlap / non-overlap is the first group, and partial overlap is the second group;

[0141] Optionally, fully overlapping / non-overlapping is one group, and overlapping / non-overlapping / partially overlapping is the second group.

[0142] For each codeword / transport block group, the first signaling consists of 1 bit, which is used to indicate whether the allocated resource mode group contains a partially overlapping resource allocation mode, where 0 ...

example 3

[0161] In this example, there are two codewords / transmission blocks (groups) to be transmitted on the transmission side. According to the method listed in this invention, these two codewords / transmission blocks (groups) are divided into two codewords / transmission blocks groups, and each codeword / transport block group is transmitted by a different transmission node.

[0162] The second signaling needs to include but not limited to indicate the PDSCH RE MAPPING and QCL status corresponding to the radio basic unit or group according to the situation that each radio resource allocation basic unit or group is occupied by different codewords / transport block groups:

[0163] Optionally, if and only when one or more radio resource allocation basic units or groups are occupied by one of the above two codeword / transport block groups, the PDSCH RE MAPPING and QCL states corresponding to the resources are transmitted accordingly This codeword / transmission block group is determined by the ...

Abstract

The invention provides a wireless resource distribution information configuration method and device. The wireless resource distribution information configuration method comprises that a base station sends wireless resource distribution information which currently-transmitted N transmission code sets or N transmission block sets respectively belong to to a terminal through a signaling method, wherein N>=1.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a configuration method and device for wireless resource allocation information. Background technique [0002] In order to improve the performance of cell edge users in the LTE-A system, a Coordinated Multi-Point (Coordinated Multi-Point, CoMP for short) transmission technology is introduced. The CoMP technology, through the coordination of multiple adjacent base stations or nodes, suppresses the same-frequency interference received by adjacent cells by cell edge users and improves the service quality of edge users. Among them, CoMP technology is mainly divided into three types: joint transmission (JT for short), dynamic node selection / dynamic node elimination (Dynamic point selection / Dynamic point Blanking, DPS / DPB for short) and cooperative scheduling cooperative beamforming (Coordinated Scheduling Coordinated beamforming, referred to as CSCB). [0003] Because in the existi...
