A method for signal processing includes receiving at a given location at least first and second signals transmitted respectively from at least first and second antennas of a wireless transmitter. The at least first and second signals encode identical data using a multi-carrier encoding scheme with a predefined cyclic delay between the transmitted signals. The received first and second signals are processed, using the cyclic delay, in order to derive a measure of a phase delay between the first and second signals. Based on the measure of the phase delay, an angle of departure of the first and second signals from the wireless access point to the given location is estimated.

A hybrid beamforming method and device are disclosed. The method may include: sending a test request of an analog beam corresponding to physical antennas and a test request of a digital beam corresponding to radio frequency (RF) front ends, the physical antennas being divided into at least two groups, in which each group of physical antennas corresponds to one of the RF front ends; within a preset test period, switching states of connection between the groups of physical antennas and the RF front ends; and after the test period is over, managing the states of connection between the physical antennas and the RF front ends according to test results for the test requests, where the test results comprise a test result for the analog beam and a test result for the digital beam.

Embodiments of the present disclosure provide a method of processing received signal using a massive MIMO base station (BS). The BS comprises a radio unit (RU), a distributed unit (DU) and an interface. The method comprises receiving a plurality of signals corresponding to the plurality of antennas, said signals comprises at least one of data signals, demodulation reference signals (DMRS) and sounding reference signals (SRS). The RU or DU performs a grouping operation on a subset of the plurality of signals corresponding to a subset of antennas to generate signal groups. The RU performs a first stage filtering on the signals associated with each group using group specific filters to obtain group specific filtered signals. The DU performs a second stage filtering on the group specific filtered signals to obtain second stage filtered signals.

A WAP including: a sounding mode module, a sounding matrix generator, a sounding aggregator, a gain normalizer and a beamforming expansion module. The sounding mode module determines whether a number of communication streams supported by the WAP matches the number of streams contained in a sounding response from a station, and initiates a composite set of soundings when those capabilities do not match. The sounding matrix generator generates linearly independent spatial mapping matrices each associated with a corresponding one of the set of composite soundings and at least one reference SMM. The sounding aggregator aggregates partial sounding feedback matrices received from the targeted station node in response to the composite soundings. The gain normalizer normalizes the partial sounding feedback matrices utilizing the reference SMM. The beamforming expansion module expands the aggregated sounding feedback matrices into a full beamforming matrix for spatially mapping downlink communications.

One embodiment of the present invention relates to a method for transmitting control information by a base station, comprising the steps of: transmitting data through a physical downlink shared channel (PDSCH); and receiving a receipt acknowledgement in response to said data in the 4.sup.th subframe following the subframe in which said data is transmitted. When downlink control information that indicates said PDSCH is transmitted in a resource region not including a resource indicated by a physical control format indication channel, the downlink control information is transmitted in k.sup.th subframe prior to the subframe in which the PDSCH is transmitted.
