Problems solved by technology

[0004] In practical applications, when a terminal performs channel detection, the resources for the detection may be allocated by the network side equipment to other terminals in the same cell for data transmission, and the channel detection of the terminal may be affected by the data transmission of other terminals in the same cell. Interference, resulting in lower accuracy of listening results

Abstract

The invention discloses a channel interception method, a network side device and a terminal, belonging to the technical field of wireless communication. The channel interception method includes the steps: the network side device determines a first interception resource for terminal channel interception, wherein the first interception resource is a resource except for the resources for data transmission of each terminal in a cell where the terminal is located; the network side device sends first interception indication information to the terminal, wherein the first interception indication information is used to indicate the first interception resource; when the terminal performs interception on the first interception resource, other terminals in the same cell do not receive or send data onthe first interception resource; and if the terminal detects an interference signal, the channel interception method can determine that the interference signal is not an interference signal generatedby other terminals in the cell when the other terminals perform data transmission, thus preventing channel interception of the terminal interfering from data transmission of the other terminals in thesame cell, and improving the accuracy of the interception result.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a channel sensing method, network side equipment and terminal. Background technique [0002] Channel sense (carrier sense, CS), also called carrier sense, refers to a process in which a terminal senses on a frequency domain resource corresponding to data transmission before initiating data transmission to a network side device. [0003] In related technologies, the network-side device schedules transmission resources for data transmission for the terminal, and when listening, the terminal listens to the channel on the frequency domain corresponding to the transmission resource scheduled by the network-side device before the time domain corresponding to the transmission resource In the case of interference, when detecting that there is channel interference in the corresponding frequency domain, the data transmission is abandoned. for data transfer. ...
