Information sending/receiving method and device

Abstract

The embodiments of the present application relate to the field of communications, and in particular to methods and devices for sending / receiving information in the field of communications. The information receiving method includes: according to the time division duplex sector scan confirmation frame count value, the total frame count value, any two of the time division duplex sector scan frame count values, the duration and time division of the time division duplex sector scan frame The duration of the duplex sector scanning confirmation frame determines the information receiving time; and the information is received at the determined information receiving time. Through the information receiving / sending method provided by the embodiment of the present application, the information sending device can send information at an accurate information sending time, the information receiving device can receive information at an accurate information receiving time, and the system communication can be carried out normally.

Description

technical field [0001] The embodiments of the present application relate to the field of communications, and in particular to methods and devices for sending / receiving information in the field of communications. Background technique [0002] In many communication scenarios, one access point / site needs to communicate with multiple access points / sites at the same time, in order to enable the one access point / site to communicate efficiently with multiple access points / sites connected to it , the size of the frame sent by the one access point / station will vary with the number of multiple access points / stations connected to it. [0003] In the prior art, when one access point / station communicates with multiple access points / stations, the calculation of many communication parameters assumes that the size of the frame sent by the one access point / station is fixed, and does not The factor that the size of the frame sent by the access point / station will change is taken into account;...

Problems solved by technology

[0003] In the prior art, when one access point / station communicates with multiple access points / stations, the calculation of many communication parameters assumes that the size of the frame sent by the one access point / station is fixed. The size of the frame sent by the access point / station will change. This factor is taken into account; as a result, the communication parameters calculated by the existing technology are inaccurate, and the inaccurate communication parameters will affect the normal communication of the communication system.
