Problems solved by technology

If the out-of-coverage terminals send data to the base station through the relay, then we call these terminals remote users (Remote UE). According to the existing method, the out-of-coverage UE can only obtain resources through the way the UE chooses to obtain resource allocation. If there are multiple D2D terminals around the Relay, and they choose resources among themselves and cannot coordinate with each other, then the data sent by the remote UE to the Relay may be interfered by or interfere with other terminals, resulting in the data from the remote UE not being received correctly
[0008] No effective solution has been proposed for the problems of data transmission and / or reception caused by the way of obtaining resources in related technologies

Embodiment 1

[0105] In this embodiment, the carrier that the relay sends data to the base station through the Uu interface is the same as the carrier that sends data to the remote UE through the PC5 interface, Figure 9 is a schematic diagram of a resource allocation method according to an embodiment of the present invention Figure 1 ,Such as Figure 9 shown, including:

[0106] Step S902, the relay determines the sending and / or receiving resource pool for the remote UE to interact with the relay, Figure 10 is a schematic diagram of a method for determining resources by a relay according to an embodiment of the present invention, such as Figure 10 shown, including:

[0107] The relay sends a resource pool application request to the base station. After receiving the request message, the base station sends and / or receives the resource pool to the relay through broadcast signaling or RRC dedicated signaling, and the relay receives the sending and / or receiving resource pool. A receiving...

Embodiment 2

[0111] The difference between this embodiment and Embodiment 1 lies in step S902. Step S902 in this embodiment determines the sending and / or receiving resource pool for the relay to interact with the relay, including: the relay receives the base station through The sending and / or receiving resource pool index sent by broadcast signaling or dedicated RRC signaling, and the relay determines the sending and / or receiving resource pool used by the remote UE to interact with the relay according to the resource pool index information. It should be noted that after the relay receives the sending and / or receiving resource pool index issued by the base station, if the relay has received the sending and / or receiving resource pool issued by the base station through dedicated RRC signaling, then the The index corresponds to the corresponding resource pool among the multiple sending and / or receiving resource pools issued by the proprietary RRC signaling. If there is no resource pool that is...

Embodiment 3

[0113] The difference between this embodiment and Embodiment 1 lies in step S902. Step S902 in this implementation determines the sending and / or receiving resource pool for the relay to interact with the remote UE and the relay, including: After selecting one or more sending and / or receiving resource pools for ProSe / unilateral service, select a subset of the sending and / or receiving resource pools as the sending and / or receiving resource pools for the remote UE to interact with the relay / or receive resource pool.

Abstract

The present invention discloses a resource processing method and device, wherein the method includes: the first terminal sends configuration information of sending and / or receiving resources / resource pools to the second terminal, wherein the resource / resource pool is used to indicate the second terminal Resource information used by the second terminal for information exchange with the first terminal. The present invention solves the problem of data transmission and / or reception caused by resource acquisition in the related art, and improves the success rate of data transmission and / or reception.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a resource processing method and device. Background technique [0002] With the development of wireless multimedia services, on the one hand, people’s demand for high data rate and user experience is also increasing; on the other hand, application scenarios such as public safety, social The demand for communication with people or things, that is, Proximity Services (referred to as PS) or sidelink (Sidelink) services is gradually increasing. As a result, higher requirements will be imposed on the system capacity and coverage of traditional cellular networks. [0003] However, the traditional base station-centric cellular network has obvious limitations in supporting high data rates and proximity services. Against this background of demand, Device-to-Device (Device-to- -Device, referred to as D2D) technology came into being. The application of D2D technology can reduce the bur...
