Problems solved by technology

[0005] However, there are the following problems in the above-mentioned D2D communication process: based on PSCCH and PSSCH resources, D2D UE can only perform one-way broadcast / multicast communication, and the transmitting UE blindly transmits D2D data, and cannot know the situation of data reception, and channel resources low utilization

[0088] Example 4 Determining the PSSCCH subframe from the PSCCH resource pool

[0089] In the D2D communication system, the subframes included in the PSSCCH resource pool are determined by the PSCCH subframes included in the PSCCH resource pool.

[0090] The period of the PSSCCH resource pool is the same as that of the PSCCH resource pool, and the PSSCCH subframe is determined by the PSCCH subframe index, that is, the PSSCCH subframe corresponds to the PSCCH subframe one-to-one, and the subframe between the PSSCCH subframe and the corresponding PSCCH subframe The interval k, where k is an integer, can be set as a constant value by the system, or indicated by high-level signaling, such as indicating the value of k through SIB signaling.

[0091] Such as Figure 8 As shown, in one period, the PSCCH resource pool contains 4 PSCCH subframes, and the system sets k=8, then it can be determined that the PSSCCH resource pool also contains 4 PSSCCH subframes, which are located at the ...

[0101] Example 6 The RBs included in the PSSCCH resource pool are determined by the RBs in the PSCCH resource pool

[0102] In a D2D communication system, the RBs contained in the PSSCCH resource pool are the same as the RBs contained in the PSCCH resource pool, and no signaling is required to indicate the RB configuration in the PSSCCH resource pool, as shown in Figure 11 shown.

[0103] The RB configuration in the PSSCCH resource pool is determined according to the RB configuration in the PSCCH resource pool, without signaling instructions, so as to achieve flexible configuration of the PSSCCH resource pool, adapt to service requirements, and reduce signaling overhead.

[0104] Example 7 The RBs contained in the PSSCCH resource pool are determined by the RBs in the PSSCH resource pool, m:1 relationship

[0105] In the D2D communication system, the RBs contained in the PSSCCH resource pool are determined by the RBs contained in the PSSCH resource pool, and the relationship between the RB quantity Mpsscch in the PSSCCH resource pool and the RB quantity Mpssch in the PSSCH resource pool is:

[0106]

[0107] Wherein, m is a positive integer, m is a constant, or is indicated by high-level signaling.

[0108] The number of RBs in the PSSCCH resource pool is determined as above, and the positions of Mpsscch RBs in the PSSCCH resource pool in the frequency domain are determined by the RB positions in the PSSCH resource pool, and the RB position index relationship can be determined according to system-defined rules or signaling instructions ,include:

[0109] When the system defines the RB position in the PSSCCH resource pool as consecutive Mpsscc...

Abstract

The invention discloses a resource pool configuration method and a resource pool configuration equipment. The method comprises steps that a physical sidelink second control channel (PSSCCH) resource pool is configured; and resources of the PSSCCH resource pool are utilized by the user equipment (UE) carrying out device-to-device communication to bear and sent the feedback control information of a physical sidelink.

Description

technical field [0001] The present invention relates to mobile communication technologies, and in particular to a resource pool configuration method and device in device-to-device (Device-to-Device, D2D for short) communication. Background technique [0002] In the D2D communication system, when there is business to be transmitted between user equipments (UE, UserEquipment), the business data between UEs is not forwarded by the base station, but is directly transmitted from the data source UE to the target UE through the air interface, such as figure 1 As shown, the wireless link between D2D UEs is called a physical side link (Sidelink). The D2D communication mode has characteristics that are obviously different from the traditional cellular system communication mode. For short-distance communication users who can apply D2D communication methods, D2D Transmission not only saves wireless spectrum resources, but also reduces the data transmission pressure of the core network, ...
