Embodiment 4

[0107] In Embodiment 4, the terminal receives the first control information, instructing the terminal to receive data channels of N (N is a positive integer greater than 1, preferably N equal to 8) carrier data resource pools, and the terminal selects the feedback resource from the feedback resource pool. to report HARQ-ACK information; the feedback resource pool is located on the same carrier where the terminal receives data.

[0108] Here is an example where two carriers are aggregated on the side link. The terminal receives the data resource of the side link downlink control channel on the first carrier, and the carrier where the feedback resource pool is located is the same as the data carrier indicated by the side link downlink control channel. From then on, the terminal ID and the receiving terminal ID are implicitly mapped to find the corresponding resource for sending side link feedback HARQ-ACK.

Abstract

The invention discloses a method for determining a sidelink feedback resource. The method is used for Internet of Vehicles carrier aggregation communication, and comprises the following steps that: adata resource pool of a first carrier is used for transmitting a sidelink data channel (PSSCH); after the sidelink data channel is ended, the earliest feedback resource which is not less than a firsttime parameter is used for transmitting sidelink feedback information (PSFCH) within a set carrier range; and the position of the feedback resource is indexed in a feedback resource pool, wherein thefeedback resource pool is a set of feedback resource configurations of at least one carrier. The invention further provides equipment and a system using the method. The method solves the problem of how to determine feedback resources under the condition of Internet of Vehicles carrier aggregation.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and device for determining side link feedback resources. Background technique [0002] The Internet of Vehicles introduces carrier aggregation. LTE-based vehicle networking wireless communication technology (LTE-V2X) is an important technical means to realize vehicle-road coordination and solve road traffic safety problems. The 3GPP Rel-14 version of the LTE V2X standard can support basic road safety-related services in V2X services, and 3GPP Rel-15 is aimed at four more advanced V2X applications, including vehicle teaming operations, advanced driving, and vehicle sensor expansion and sharing. , and remote driving, the project approval of the V2X Phase 2 standard project was carried out. Among them, for the goal of increasing the data transmission rate, 3GPP takes the carrier aggregation of the V2X direct link as the research direction, in ...
