The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described techniques can be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, although the techniques may also be applied to applications other than NR system applications, such as 6 th generation (6 th generation)^thGeneration, 6G) communication system.

In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is made.

The following description of the sildelink resource allocation, CR and CBR follows.

1. And allocating the Sidelink resources.

NR V2X defines two resource allocation modes, one mode1, for scheduling resources for the base station; the other is mode2, the UE itself decides what resources to use for transmission. The resource information may come from a broadcast message of the base station or preconfigured information at this time. The UE may be mode1 and/or mode2 if it is operating within range of the base station and has an RRC connection with the base station, and the UE may only be in mode2 if it is operating within range of the base station but has no RRC connection with the base station. If the UE is out of range of the base station, it can only operate in mode2, performing V2X transmissions based on the preconfigured information.

For mode2, the specific operation is as follows: 1) a sender (TX) UE first determines a resource selection window after resource selection is triggered, where a lower boundary of the resource selection window is at time T1 after resource selection is triggered, and an upper boundary of the resource selection window is at time T2 after the resource selection is triggered, where T2 is a value selected by the UE in a pdb (packet delay budget) transmitted by its Transport Block (TB), and T2 is no earlier than T1. 2) Before resource selection, the UE needs to determine a candidate resource set (candidate resource set) for resource selection, compare a Reference Signal Receiving Power (RSRP) measured on a resource in a resource selection window with a corresponding RSRP threshold (threshold), and if the RSRP is lower than the RSRP threshold, the resource may be included in the candidate resource set. 3) And after the resource set is determined, the UE randomly selects transmission resources in the alternative resource set. In addition, the UE may reserve transmission resources for the next transmission in the current transmission.

2、CR。

The calculation of CR is based on the priority of the UE to transmit traffic, i.e. for each traffic priority, there will be one CR value. The method is that at the current time n, if the priority of the service to be transmitted at the sending end is q, statistics of [ n-a, n-1 ] is needed]The UE counts the number A of resources used for the traffic transmission with the priority q in the transmission resource pool and counts the number [ n, n + b ]]In the time period of (2), the UE reserves resource quantity B for service transmission with priority q in the transmission resource pool; at [ n-a, n + b]C, then (a + B)/C for CR with priority q, wherein a + B +1 equals 1000 or 1000 x 2^uA physical slot. The frequency domain granularity of the resource is a sub-band, and the time domain granularity is one slot.

When reserving resources, assuming that the priority of the service currently needing to be transmitted is q, the restrictions on CR are as follows:

∑_i≥qCR(i)≤CR_Limit(q)；

wherein, CR_Limit(q) is configured by higher layer parameters. This restriction means a CR restriction for a service having a priority equal to or less than q and a service not greater than the priority q. This limitation is used for congestion control on sidelink.

3、CBR。

The CBR is used for measuring the busy characteristic of a channel in the whole system, and the specific calculation mode is that at the current time n, statistics of [ n-a, n-1 ] is needed]In the time period of (3), the number of resources in the resource pool, in which the RSSI exceeds the threshold value T, is a, the total number of resources in the resource pool is B, the CBR is a/B, wherein a is 100 or 100 × 2^uA physical slot. The frequency domain granularity of the resource is a sub-band, and the time domain granularity is one slot.

In a resource allocation mode (mode2) autonomously selected by a User Equipment (UE) on a New Radio (NR) Sidelink (also called Sidelink, or Sidelink), the UE reserves transmission resources each time on the premise that the ratio of the resources reserved by the UE in a time window to the total resources in the time window needs to satisfy a certain threshold requirement. At present, in order to improve transmission reliability, a method of indicating or recommending resources by a receiving end is expected to be introduced, and a sending end transmits data on the resources indicated or recommended by the receiving end, so that the problem of low transmission reliability caused by a half-duplex problem and a hidden node problem is solved. However, after the mechanism is introduced, the calculation methods of the related CR and CBR are no longer applicable, and when resource recommendation or indication is performed, situations such as resource conflict or channel congestion occur, and it is difficult to ensure the reliability of transmission.

The embodiment of the application provides a resource indication method, which is applied to a first communication device, wherein the first communication device can be a first terminal or a control node, and the method comprises the following steps:
