Description

Processing method and device of resource selection window, terminal and readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for processing a resource selection window, a terminal, and a readable storage medium.

Background

The method for allocating resources based on perception in a direct link (Sidelink, side link, etc.) mainly comprises: resource awareness, resource exclusion, resource selection, resource preemption and reselection. And under the condition that the terminal does not transmit, the terminal continuously performs sensing (monitoring external information), and when the terminal needs to transmit information, the terminal excludes unavailable resources according to the result sensed in a previous period of time and selects the resources capable of transmitting the information for transmission.

For example, by the sequence of the sequences [ n-T0, n-T _proc,0 ]The perceived result during this time (where T _proc,0 To include the processing time of the decoded perceived resource), a window [ n+T1, n+T2 ] is selected over the resource]Internal selection resource, the starting boundary T1 of the window is less than or equal to Tplc and 1, depending on the terminal capability, tplc and 1 are transmission processing delays, the ending boundary T2 of the window meets T2min less than or equal to T2 less than or equal to PDB (Packet Delay Budget ), the value of T2 depends on the terminal implementation, and T2 _min Refers to the minimum value that T2 may take, depending on the priority of the traffic.

In summary, in the prior art, the upper limit of the resource selection window is the remaining packet budget, where the priority is higher, but the packet delay budget is larger, the terminal may select a larger resource selection window, and when the channel is idle, the terminal may actually transmit with a smaller delay, but the delay of transmitting the resource selected according to the existing mechanism is larger. In addition, the minimum range of the existing resource selection window is only related to the priority, and the smaller the window is when the priority is higher, but when the channel is idle, the minimum range of the window of the service with lower priority may be larger, resulting in unnecessary delay.

According to the size of the resource selection window under each condition parameter, the resource selection window is divided into 4 grades from small to large, namely, each condition parameter takes a value in {1,2,3,4 }; the size of T2max is determined by three condition parameters of priority, CBR, CR, set to A, B, C.

As shown in fig. 2, assuming a=2, b=2, c=1, then m=a+b+c=5, n1=3, c=4; then

And comparing the value list of the T2max, and determining that the value of the upper limit value T2max of the first parameter is 150 if the value corresponding to the index value of 7 is 150.

Mode two, step 101, includes:

acquiring n2 condition parameters reaching the window upper limit reduction threshold; n2 is an integer greater than or equal to 1; the above reaching of the window upper limit reduction threshold can be understood as: the value of the condition parameter is larger than or equal to the window upper limit reduction threshold, or the value of the condition parameter is smaller than or equal to the window upper limit reduction threshold, and can be specifically determined according to the condition parameter;

In this method, the upper limit value T2max of the first parameter is determined based on one or more conditions of the priority and the maximum retransmission number of CBR, CR, HARQ on the basis of the packet delay budget (Packet Delay Budget, PDB) of the determined traffic. It should be noted that this mode is generally triggered when the value of PDB of the traffic to be transmitted is greater than a specific threshold w, and there is a condition parameter that reaches the window upper limit reduction threshold.
