[0040] Such as figure 1 As shown, the embodiment of the present invention provides a resource selection method, which is applied to a terminal, such as a portable terminal (P-UE), and the method specifically includes the following steps:

[0041] Step 11: Select transmission resources for the first M transmissions of service packets by performing resource awareness;

[0042] In this step, M≥1, which includes selecting initial transmission resources only for service packets by performing resource sensing, or selecting initial transmission resources and part of retransmission resources for service packets by performing resource sensing.

[0043] Specifically, by performing resource sensing, the sensing information such as the resource occupation of other terminal nodes and the reservation of subsequent resources is obtained, and the appropriate M transmission resources are selected for the service package according to the sensing information. It mainly involves two windows, the...

Abstract

The invention provides a resource selection method and device and a terminal, and the method is applied to the terminal, and comprises the steps: selecting transmission resources for the first M timesof transmission of a service packet by executing resource sensing; transmission resources are randomly selected for N times of transmission after M times of transmission; wherein N + M is the total transmission frequency of the service packet, N is greater than or equal to 1, and M is greater than or equal to 1. According to the scheme, for the terminal sensitive to power consumption, the power saving efficiency can be improved while the transmission reliability is considered during resource selection.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a resource selection method, device and terminal. Background technique [0002] V2X (Vehicle-to-Everything, Vehicle-to-Everything) technology is continuously gaining support from the ecosystem. In a V2X system, how to reduce power consumption while ensuring the reliability of data sent by the UE is a problem that needs to be solved for the UE, especially the UE sensitive to power consumption (such as a portable terminal P-UE). [0003] At present, the existing resource selection schemes include random resource selection and partial sensing resource selection. The random resource selection scheme does not require sensing and is the most effective in saving power consumption. In the case of being occupied, the resource collision probability is high, the transmission reliability is low, and the system performance is greatly affected; the partial sensing resourc...
