Embodiment Construction

[0064] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0065] refer to figure 1 , figure 1 A flow chart of a method for allocating secondary link resources provided by an embodiment of the present invention is shown, and specific steps are described in detail below.

[0066] In step S101, a first UE receives a secondary link resource allocation request message groupcast by a second UE, the first UE and the second UE being located in a first group.

[0067] In some embodiments, the secondary link resource allocation request message includes a secondary link resource allocation request and request content, and step S101 includes: the first UE receiving the secondary link resource multicast by the second UE an allocation request; multicast a confirmation message corresponding to the secondary l...

Abstract

The invention provides a method and a device for allocating and acquiring sidelink resources, and a computer readable medium. The allocation method comprises: first UE receives a sidelink resource allocation request message multicast by second UE; selecting sidelink resources corresponding to the sidelink resource allocation request message; and multicast or broadcast of a sidelink resource allocation response message is carried out, the sidelink resource allocation response message indicating the selected sidelink resources. The acquiring method comprises the steps that the second UE judges whether data to be sent exist or not; if so, multicast of the sidelink resource allocation request message is carried out to request transmission of the sidelink resources required by the to-be-sent data; and receiving the sidelink resource allocation response message from the first UE, wherein the sidelink resource allocation response message comprises sidelink resources selected by the first UE for the second UE. By adoption of the scheme of the invention, the UE in the NR-V2X technology can realize selection, allocation and acquisition of the sidelink resources.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for allocating and acquiring secondary link resources, and a computer-readable medium. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution)-V2X (Vehicle to everything, vehicle-to-everything) technology, if a UE (User Equipment, user terminal) performs secondary link resource selection or re-selection at time n, the UE will select or re-select secondary link resources at time n. Sensing is performed within the sensing window within the previous 1000 ms. Specifically, the UE obtains the positions of the secondary link resources reserved for the transmission data of other UEs by decoding the SCI (Sidelink Control Information, secondary link control information) sent by other UEs, so as to exclude these reserved resources in the resource selection window , so the UE performs energy measurement in the remaining resources to...
