Abstract

Embodiments of the present disclosure relate to a method and device for beam forming. In example embodiments, a plurality of signals are obtained from a plurality of receiving antennas. The pluralityof signals are grouped into a first set of signals and a second set of signals. An automatic gain control (AGC) is disabled for each signal in the first set of signals, and the AGC has been enabled for each signal in the second set of signals. Then, for beam forming associated with the plurality of receiving antennas, beam weights are determined by applying a first set of signal weights to the first set of signals and applying a second set of signal weights to the second set of signal weights. The first set of signal weights are greater than the second set of signal weights. In this way, negative effects due to the AGC processing may be mitigated in the beam forming.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the communication field, and in particular, relate to a method and device for beamforming. Background technique [0002] Massive multiple-input multiple-output (MIMO) technology utilizes a large number of serving antennas that operate adaptively and coherently. Additional antennas help to concentrate the energy of a transmitted or received signal into a very small area of ​​space. In the case of simultaneous scheduling of a large number (eg, tens or hundreds) of user terminals, this technique brings about huge improvements in throughput and energy efficiency. Massive MIMO can also bring other benefits, which can include, for example, wider use of inexpensive low-power components, reduced latency, simplified medium access control (MAC) layers, and improved robustness to jamming and intentional jamming sex. Massive MIMO can be applied to both time division duplex (TDD) and frequency division du...
