Abstract

A wireless communication device with a memory sharing mechanism includes a communication circuit, a memory circuit, and a processing circuit. The processing circuit executes the following steps of: connecting the communication circuit with a remote wireless communication device to perform channel detection and communication; causing the communication circuitry to receive compressed channel state information generated by the remote wireless communication device; storing the compressed channel state information in a memory circuit; generating original channel state information according to the state of the wireless channel; when the residual capacity of the memory circuit is insufficient, enabling the communication circuit to reduce the number of channel sounding with the remote wireless communication device, and removing correspondingly stored compressed channel state information from the memory circuit; and storing the original channel state information in a memory circuit.

Description

technical field [0001] The present invention relates to a memory sharing technology, and more particularly, to a wireless communication device with a memory sharing mechanism and a memory sharing method thereof. Background technique [0002] In wireless communication technologies such as WiFi, the wireless communication device can estimate the frequency response of the orthogonal sub-carriers in the system by measuring the preamble signal sent by the transmitter, which is called channel state information (channel state information). state information; CSI). Each subcarrier will have an estimated channel state information, which is usually expressed in multiples. In many current communication systems, the station device estimates the channel through the probe packets transmitted by the access point device, and then decomposes and compresses the channel information to generate compressed channel state information (compressed CSI) for return. The access point device can judge...
