Problems solved by technology

[0010] However, when a node selects a time slot, two nodes that are listening at the same time, or two nodes that are still in the process of time slot selection, and two nodes that have not yet sent information on the selected time slot, can easily choose the same time slot As their respective self-occupied time slots, resource collisions are caused, and resource reselection is performed frequently, which affects the reliability of the system

Embodiment Construction

[0043] The embodiment of the present invention provides a resource selection method and device, which are used to select two resources each time a node selects a resource, one is used to transmit a service package, and the other is used to indicate the resource for transmitting the service package, so that When receiving the instruction, other nodes can select different resources to occupy according to the instruction, so as to avoid resource collision and frequent resource reselection, which improves the reliability of the system.

[0044] See figure 1 , A resource selection method provided by an embodiment of the present invention includes:

[0045] S101. Determine the resource that needs to be selected for transmitting the service package;

[0046] S102. Select a first resource and a second resource, where the second resource is used to transmit the service package, the first resource is used to indicate that the second resource needs to be occupied to transmit the service package...

Abstract

The invention discloses a resource selection method and device, which are used to select two resources each time a node selects a resource, one is used to transmit a service package, and the other is used to indicate the resource for transmitting the service package, so that other When the node receives the instruction, it can select different resources to occupy according to the instruction, so as to avoid resource collision and frequent resource reselection as far as possible, and improve the reliability of the system. A method for selecting resources provided by the present invention includes: determining resources that need to be selected for transmitting service packages; selecting first resources and second resources, wherein the second resources are used for transmitting service packages, and the first resources are used for transmitting service packages. In order to indicate that the second resource needs to be occupied to transmit the service packet, wherein the resource is a time slot or a time-frequency block.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for resource selection. Background technique [0002] In the cellular-assisted distributed resource allocation algorithm, the existing time slot selection mechanism still has a high collision probability, which reduces system performance. [0003] A base station-assisted implicit reservation resource allocation algorithm in the prior art includes: a resource competition method. The user equipment (UE) needs to monitor the channel for a period before sending a signal for the first time. If a certain logical resource in a certain period is found No other UEs can use the same logical resource location in the next cycle. Once the competition is successful, the same logical resource will be used to send information in each subsequent cycle until the resource collides again. Before the collision is released and there is no additional service sending require...
