example 1

[0081] Example 1: If the resource occupancy rate of carrier 1 is 50%, the remaining available resources are 20 subchannels, the resource occupancy rate of carrier 2 is 40%, and the remaining available resources are 10 subchannels, the configured resource occupancy weight is 0.6, and the remaining Available resources have a weight of 0.4;

[0082] The selected factor of carrier 1 is: P1=0.6*(1-0.5)*100+0.4*20=38;

[0083] The selection factor of carrier 2 is: P2=0.6*(1-0.4)*100+0.4*10=40;

[0084] The terminal selects carrier 2 as the sending carrier.

example 2

[0085] Example 2: The resource occupancy rate of carrier 1 is 50%, the remaining available resources are 20 subchannels, the resource occupancy rate of carrier 2 is 40%, the remaining available resources are 10 subchannels, the configured resource occupancy weight is 0.4, and the remaining available resources The resource has a weight of 0.6;

[0086] The selected factor of carrier 1 is: P1=0.4*(1-0.5)*100+0.6*20=32;

[0087] The selection factor of carrier 2 is: P2=0.4*(1-0.4)*100+0.6*10=30;

[0088] The terminal selects carrier 1 as the sending carrier.

example 3

[0089] Example 3: There are 4 candidate carriers corresponding to the service priority sent by the terminal, and the terminal needs to select 2 of them as the sending carrier. The resource occupancy rate of carrier 1 is 50%, and the remaining available resources are 20 subchannels; the resource occupancy rate of carrier 2 is 40%, and the remaining available resources are 10 subchannels; the resource occupancy rate of carrier 3 is 30%, and the remaining available The resources are 25 sub-channels, the resource occupancy rate of carrier 4 is 40%, the remaining available resources are 20 sub-channels, the weight of the configured resource occupancy rate is 0.4, and the weight of the remaining available resources is 0.8;

[0090] The selected factor of carrier 1 is: P1=0.4*(1-0.5)*100+0.8*20=36;

[0091] The selected factor of carrier 2 is: P2=0.4*(1-0.4)*100+0.8*10=32;

[0092] The selected factor of carrier 3 is: P3=0.4*(1-0.3)*100+0.8*25=48;

[0093] The selected factor of ca...

Abstract

The invention discloses a carrier selection method and communication equipment, wherein the carrier selection method includes: when selecting a carrier, selecting a sending carrier according to service priority, resource occupancy rate of an alternative carrier and remaining available resources. The scheme of the present invention performs carrier selection in combination with resource occupancy rate and remaining available resources, and realizes support for carrier aggregation and optimal selection of carriers and resources.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a carrier selection method and communication equipment. Background technique [0002] In the current 3GPP protocol version, LTE-V2X performs service transmission on a single carrier, does not support carrier aggregation, and only selects transmission resources on a single carrier, and does not support carrier selection in the case of multiple carriers. [0003] Currently, the selection of transmission resources on a LTE-V2X single carrier includes the following steps: [0004] Step1: Mark all candidate resources in the resource selection window as available; [0005] Step2: Exclude occupied resources, including 2 categories, such as figure 1 as shown, [0006] The first type is in the sensing (sensing) window, UE (terminal) sends by itself and cannot monitor the service packets sent by other UEs on the sending subframe. The above subframe becomes a skip (skip) su...
