Embodiment 1

[0096] Embodiment 1: The UE obtains the auxiliary information "whether the receiving UEs in the D2D communication group are all on the network" from the network, and determines that the predefined resource or the resource pool configured by the network should be used according to the auxiliary information.

[0097] In this embodiment, the specific processing steps are as follows:

[0098] (1) The network obtains auxiliary information and informs the UE through signaling

[0099] (2) The UE selects the resource pool that should be used according to the auxiliary information

[0100] (3) The UE performs distributed resource selection in the determined resource pool.

[0101] For step (1), since there is a D2D communication server (D2D server) on the core network side, the server stores service information related to D2D users, for example, it may include service characteristics and requirements, service group affiliation information, and the like. When determining the network ...

Embodiment 2

[0113] Embodiment 2: The UE obtains the auxiliary information "using a predefined or network-configured resource pool" from the network, and directly uses the resource pool for resource selection.

[0114] The difference between the specific process of this embodiment and that of Embodiment 1 is that after the network obtains the auxiliary information from the core network, it first judges that the UE should use a predefined resource pool or a resource pool configured on the network side, and then directly indicates the decision to the UE. After receiving the instruction, the UE performs distributed resource selection similar to step (3) in Embodiment 1 according to the indicated resource pool.

[0115] According to an embodiment of the present invention, a resource allocation device for D2D signal transmission is also provided.

[0116] like Figure 6 As shown, the resource allocation device according to the embodiment of the present invention includes:

Abstract

The invention discloses a resource distribution method used for device to device signal transmission and an apparatus. The resource distribution method comprises the following steps of determining an online condition of user equipment UE in a D2D communication group; according to the determined online condition, sending auxiliary information to the UE, wherein the auxiliary information comprises at least one of an indication whether the UE in the D2D communication group is online and indication information used for indicating a resource pool used by the UE to transmit a D2D signal. A base station sends the auxiliary information to the UE so that the resource pool used by the online UE is defined according to the online condition of the UE in the current D2D communication group. The online UE and offline UE can be guaranteed to use a resource transmission D2D signal in the same resource pool so that normal transmission of the D2D signal is guaranteed; resource distribution efficiency is increased and D2D communication performance is improved.

Description

technical field [0001] The present invention relates to the field of computers, and in particular to a resource allocation method and device for device-to-device (Device to Device, D2D) signal transmission, and a determination method and device. Background technique [0002] (1) Existing mobile communication system [0003] In a Long Term Evolution (LTE for short) system, a network centralized control method is usually adopted, that is, as figure 1 As shown, the uplink and downlink data of the user equipment (User Equipment, referred to as UE) are all sent and received under the control of the network (for example, communicating with the core network through the base station (eNodeB)), and the communication between the UE and the UE It is also forwarded and controlled by the network, so there is no direct communication link between UEs, and UEs are not allowed to send uplink data by themselves. exist figure 1 In the communication mode shown, there is no direct link betwee...
