example 1

[0141] Example 1. The Relay UE indicates to the Remote UE part of the resources used by the Relay UE for sending data.

[0142] Such as Figure 2B As shown, the off-network and on-network D2D interface receiving resource pools include resources on one or more subframes in the period of resource blocks 1 to 13), where each resource block is composed of several physical resource units, and the size of the resource block can be different.

[0143] Resource blocks 1-5 are the first transmission resource pool of the Relay UE, and resource blocks 1-4 and resource blocks 6-8 are the transmission resource pools of the Remote UE.

[0144] The Relay UE judges that resource blocks 1, 2 and 5 need to be occupied as the first resource group according to the traffic volume of all the Remote UEs served, and notifies each Remote UE of the physical resource information corresponding to the resource blocks 1, 2 and 5.

[0145] The Remote UE receives the above information sent by the Relay UE,...

example 2

[0147] Example 2. The Relay UE indicates to the Remote UE some of the resources that the Remote UE can use to send data

[0148] Such as Figure 2B As shown, the off-network and on-network D2D interface receiving resource pools include resources on one or more subframes in the period of resource blocks 1 to 13), where each resource block is composed of several physical resource units, and the size of the resource block can be different.

[0149] Resource blocks 1-5 are the first transmission resource pool of the Relay UE, and resource blocks 1-4 and resource blocks 6-8 are the transmission resource pools of the Remote UE.

[0150] The Relay UE judges that resource blocks 1, 2, and 5 need to be occupied as the first resource group according to the traffic volume of all Remote UEs served, and the Relay UE will receive other resource blocks in the resource pool (that is, resource blocks 3, 4, 6-13) The corresponding physical resource information is notified to each Remote UE. ...

example 3

[0152] Example 3. The Relay UE indicates to each Remote UE the partial resources it can use to send data

[0153] The Relay UE serves 3 Remote UEs, Remote UE1, Remote UE2 and Remote UE3.

[0154] Such as Figure 2B As shown, the off-network and on-network D2D interface receiving resource pools include resources on one or more subframes in the period of resource blocks 1 to 13), where each resource block is composed of several physical resource units, and the size of the resource block can be different.

[0155] Resource blocks 1-5 are the first transmission resource pool of the Relay UE, and resource blocks 1-4 and resource blocks 6-8 are the transmission resource pools of the Remote UE.

[0156] The resource blocks allocated by the Relay UE to multiple Remote UEs may be divided in the time domain, that is, different resource blocks are in different time slots or subframes, or may be divided in the frequency domain, that is, different resource blocks are in different PRBs. ...

Abstract

The embodiment of the invention relates to the technical field of wireless communication, and particularly relates to a method for data transmission and equipment thereof and aims at solving problems in the prior art that a UE cannot receive data transmitted by other UEs at the same time of transmitting in the D2D transmission process and packet loss is generated. According to the method, a first terminal selects a first resource group used for transmitting of the first terminal from the first transmitting resource pool of the first terminal; and a second terminal group is configured so that each second terminal is enabled not to transmit data to the first terminal via the first resource in the first resource group. The second terminals are enabled not to transmit the data to the first terminal via the first resource in the first resource group so that a situation of packet loss caused by the fact that the data transmitted by other UEs cannot be received at the same time of transmitting can be avoided, and thus transmission efficiency is further enhanced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for data transmission. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) system, a network centralized control method is adopted, that is, both uplink and downlink data of UE (User Equipment) are sent and received under the control of the network. Communication between UEs is forwarded and controlled by the network. There is no direct communication link between UEs, and UEs are not allowed to send uplink data by themselves, see Figure 1A . [0003] D2D (Device-to-Device, device-to-device), that is, user equipment direct technology, refers to the way that adjacent user equipment can transmit data through a direct link within a short distance without passing through a central node (ie, a base station). ) for forwarding, such as Figure 1B shown. [0004] In 3GPP (3rd Generation Partnership Project, th...
