Abstract

The invention discloses a group communication method. The group communication method comprises the following steps of transmitting a buffer state report (BSR) to base station equipment; acquiring time frequency resources distributed by the base station equipment to user equipment; distributing time frequency resources to a group of the user equipment according to a priority value; and performing group communication with other user equipment which is distributed to the group of the time frequency resources. The BSR carries at least one group index, each group index corresponds to group recognition codes of at least one group of the user equipment, each group index or each group recognition code reflects a predefined priority value so that the base station equipment can distribute the time frequency resources for different user equipment according to the priority value. Correspondingly, an embodiment of the invention also discloses user equipment, base station equipment and a group communication system. By the group communication method, required resources of group communication can be distributed reasonably, and business quality is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a group communication method, user equipment, base station equipment and system. Background technique [0002] With the continuous development of wireless communication technologies, direct device to device communication (Device to Device, D2D) has become one of the hot spots of 3GPP Rel-12 standardization technology. D2D allows two user equipment (User Equipment, UE) to directly transmit data through a specific channel (Sidelink Channel) without going through an evolved base station device (Evolutional Node B, eNB). Of course, D2D is not limited to two users Data transmission between devices can also support point-to-multipoint group communication (Group Communication). For example, see Figure 7 , as shown in the figure, SRC UE represents the source UE (that is, the UE that sends data), and DST UE represents the target UE (that is, the UE that receives d...
