Abstract: Provided are a multi-link device, a communication device, and a storage medium. The device includes: M stations, where the stations are non-access point (AP) stations, each station forms a respective communication link, the M stations form M communication links, and the M communication links communicate through P single wireless channels. M is greater than P, and P is greater than or equal to 1.

Abstract: Provided in embodiments of the present disclosure are a service access method, apparatus and system. The service access method includes: obtaining a low-latency service access request or low-latency service access information of a station; and entering a low-latency service access operation mode, wherein at least one first contention period is configured in the low-latency service access operation mode, the first contention period is dedicated for channel access of data of a low-latency service of the station, and the low-latency service is a service satisfying a preset low-latency service condition.

Abstract: Provided are a delay performance evaluation method and apparatus and a storage medium. The delay performance evaluation method includes sending, by a first communication node, an evaluation data unit to a second communication node; receiving, by the first communication node, an evaluation feedback data unit which is sent by the second communication node and sent according to the evaluation data unit; and according to a transmission condition of the evaluation data unit and the evaluation feedback data unit, acquiring, by the first communication node, a delay evaluation parameter caused by internal communication contention or control of a BSS where the first communication node is located and/or a delay evaluation parameter caused by an external interference of the BSS.

Abstract: Provided are a delay performance evaluation method and apparatus and a storage medium. The delay performance evaluation method includes evaluating, by a communication node, a delay performance involved in an internal communication environment of a basic service set (BSS) where the communication node is located according to pre-acquired delay evaluation parameters caused by internal communication contention or control of the BSS; and/or evaluating, by a communication node, a delay performance involved in an external interference of a BSS where the communication node is located according to pre-acquired delay evaluation parameters caused by the external interference of the BSS.

Abstract: Provided is a coding control method in a passive optical network (PON). The method includes acquiring data of a service to be coded and a preset codeword length N corresponding to the service to be coded; acquiring a coding mode corresponding to the preset codeword length N in a preset table describing a correspondence between codeword length ranges and coding modes; and coding data of the service by using the coding mode corresponding to the preset codeword length N. Further provided are a coding control apparatus in a PON, a communication device and a storage medium.
