Embodiment Construction

[0031] image 3 A wireless communication method according to an embodiment of the present invention is schematically shown. like image 3 As shown, at time slot t, the sending communication device S performs the first transmission to send the first signal to the relay device RS and the receiving communication device D. The relay device RS decodes the received first signal, judges whether the decoding result is correct, and generates a first decoding response signal indicating whether the decoding is correct, wherein, if the decoding is correct, the first decoding response signal is an ACK signal, and if the decoding is wrong, the first decoding response signal is a NACK signal. At time slot t+k, the relay device RS sends a first decoding response signal to the sending device S and the receiving communication device D. If the decoding is correct, the relay device RS performs a second transmission at time slot t+n to forward the first signal to the receiving communication dev...

Abstract

The invention provides relay equipment for a wireless communication system and a wireless communication method for the relay equipment. The wireless communication method comprises the steps of receiving a first signal with second communication equipment as the destination from first communication equipment, decoding the received first signal, judging whether the decoding result is correct or not, generating a first decoding response signal which indicates whether the decoding result of the first signal is correct or not, and transmitting the first decoding response signal to the first communication equipment and the second communication equipment. The method can reduce waste of resources in the wireless communication system.

Description

technical field [0001] The present invention relates to the field of wireless communication systems, in particular to a relay device and a wireless communication method for the relay device. Background technique [0002] With the rapid development of wireless multimedia services, users have higher and higher requirements on data communication capabilities and transmission quality. However, due to the influence of obstacles, shadows and other factors in the complex wireless environment, many communication dead spots are formed. These will make it difficult for users to obtain continuous high-speed and high-quality communication services. In order to solve this problem, the wireless system uses relay equipment to forward the wireless communication signals between the wireless communication parties to improve the system throughput and user data rate. [0003] A wireless communication system using a relay device generally includes a sending communication device, a relay device...
