Abstract

The application provides an indication method, a use method, an indication device and a use device for resource allocation. The method comprises the steps that target UE broadcasts transmission channel resource information, wherein the number of hidden nodes existing in a preset range of the target UE accords with preset conditions, and the transmission channel resource information is used for indicating transmission channel resources of data received by the target UE. The method solves the technical problem that different UE selects the same transmission resource due to the hidden node, thereby generating resource conflict.

Description

Indication method, use method, indication device and use device for resource allocation Technical Field The present application relates to the field of communications, and in particular, to a method for indicating resource allocation, a method for using resource allocation, a device for indicating resource allocation, a device for using resource allocation, a processor, and a communication system. Background For V2X (vehicle to everything, vehicle-to-outside information exchange) transmission in an NR (New Radio) network, a UE (User Equipment) may autonomously select a resource according to a certain rule to perform information transmission. The UE determines candidate resources through a sensing process, then randomly selects the resources of the next first transmission and the subsequent multiple transmissions in the candidate resources, indicates the resources used for the current transmission in SCI (Sidelink Control Information, side chain control information) of each transmission, and indicates the reservation period of the resources. However, due to the existence of the hidden node, the UE cannot perceive the transmission resource of the hidden node in the process of perceiving the resource, so that different UEs select the same transmission resource to perform data transmission, and thus, collision occurs, and normal data transmission cannot be performed. For the scene that more hidden nodes exist in a network, the conventional scheme for transmitting the cooperative information has the problems that part of UE which does not participate in the transmission/reception of the cooperative information cannot acquire the potential hidden nodes through the UE-A and still has the problem of resource conflict, and for the UE-A, if the UE-A transmits the cooperative information based on the request message of the UE-B, the UE-B can select the same transmission resources as the hidden nodes around the UE-A in the process of transmitting the request message, so that the conflict is generated and the request message cannot be transmitted correctly. Disclosure of Invention The application mainly aims to provide a resource allocation indicating method, a resource allocation using method, a resource allocation indicating device, a resource allocation using device, a processor and a communication system, so as to solve the problem that in the prior art, different UE select the same transmission resource to generate resource conflict due to hidden nodes. According to one aspect of the embodiment of the invention, an indication method of resource allocation is provided, which comprises the steps that a target UE broadcasts transmission channel resource information, wherein the number of hidden nodes existing in a preset range of the target UE accords with a preset condition, and the transmission channel resource information is used for indicating transmission channel resources of data received by the target UE. Optionally, determining the target UE comprises determining that all the UEs with the distance from the first UE being smaller than a first threshold value are second UEs, determining the number of first combinations with the distance from the two second UEs being larger than a second threshold value in two-to-two combinations of the second UEs, and determining that the first UE is the target UE when the number of the first combinations is larger than a third threshold value. Optionally, determining the first UE includes determining that the UE located at the center position of the cluster is the first UE in a case where the UEs in the cell are distributed in units of clusters. Optionally, determining the first UE includes determining a second combination in which the variation of the distance between two UEs in a preset period is smaller than a fourth threshold, and determining that the same UE is the first UE when the number of the second combinations including the same UE is greater than a fifth threshold. Optionally, the target UE acquires the transmission channel resource information according to SCIs sent by other UEs, where the SCIs are carried by a PSSCH channel or a PSCCH channel.

Optionally, the congestion degree of the PSSCH channel or the PSCCH channel is determined according to at least one of CBR and CR, and/or the target UE stops broadcasting the transmission channel resource information when the congestion degree is not greater than the sixth threshold, and/or stops broadcasting the transmission channel resource information when the congestion degree is not less than the seventh threshold.
