Description

technical field

[0001] The present invention relates to a communication method and device, in particular to a communication method and device for a mobile terminal with multiple antenna array elements. technical background

[0002] Multi-antenna (multiple-antenna) technology usually uses two or more single-antenna elements to form an antenna array, and adjusts the phase of the received signal by weighting the signal received by each antenna element. And the amplitude, so that after the received signal is weighted and summed, the required signal is strengthened, and the interference signal is weakened. Compared with the traditional single-antenna technology, the multi-antenna technology has a good application prospect in the communication field due to its special advantages in overcoming multi-path interference problems.

[0003] In the wireless communication system, the multi-antenna technology can not only be applied to the base station to improve the signal receiving perf...
