摘要： Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit feedback to a base station indicating phase values for sub-bands in a bandwidth part (BWP). The base station may use the phase feedback to perform precoding on a set of beams. To support a reduced payload overhead for the feedback, the UE may implement differential phase feedback. For example, the UE may divide the BWP into a number of sub-band groups and may generate, for each sub-band group of each beam, a first set of bits indicating an absolute phase value for a first sub-band of the sub-band group. The UE may additionally generate a second set of bits indicating differential phase values for the other sub-bands of each sub-band group. The UE may report the first and second sets of bits for the beams to the base station for precoding.

摘要： Methods, apparatuses, and computer program products are disclosed for facilitating decoding a communication received from a wireless terminal. Encoded bits are received from the wireless terminal via a shared uplink channel, and a plurality of acknowledgment tones are identified within the encoded bits. A correlation value is ascertained corresponding to a correlation between detected bits within the plurality of acknowledgment tones and valid bits corresponding to any of a plurality of valid acknowledgment codewords. A determination is then made as to whether the plurality of acknowledgment tones includes information corresponding to a discontinuous transmission by comparing the correlation value to a threshold value.

摘要： Aspects are described for reducing interference in wireless systems. In a first embodiment, an uplink acknowledgment region associated with a macro cell is determined, and an assignment of uplink control resources is restricted to a region within the uplink acknowledgment region. A control signal is then transmitted to user equipment via the assignment of uplink control resources. In another embodiment, control signals are received from wireless terminals, which include desired uplink control signals associated with an access point base station, as well as interfering uplink acknowledgement signals associated with macro cells. The control signals may then be regenerated by cancelling the set of interfering signals from the control signals. The desired uplink control signals are then decoded.

摘要： Methods, systems, and devices for wireless communication are described that support a low peak-to-average power ratio (PAPR) precoded reference signal design for multiple-input, multiple-output (MIMO) transmissions. A user equipment (UE) may identify multiple sets of symbols associated with different reference signal waveforms, where each reference signal waveform may be associated with a low PAPR. In some cases, different single-carrier reference signal waveforms may be mapped to subsets of frequency resources through frequency division multiplexing (FDM) for a transmission on a single antenna. However, the addition of single-carrier waveforms through FDM for a transmission via an antenna may result in an uplink transmission having a high PAPR (e. g., as compared to single-carrier waveforms). The UE may reduce the PAPR of the uplink transmission by multiplexing the reference signal waveforms in the time domain (e. g., using time division multiplexing (TDM)).

摘要： Blind interference cancellation is described for wireless networks in which a subject base station or cancellation apparatus obtains semi-static information for at least one of its neighboring cells. The base station measures the noise level of each of the neighboring cells based on samples it takes of uplink transmissions in each of the neighboring cells. The neighboring cells are then ranked for interference cancellation based on their relative noise levels. The base station performs discontinuous transmission (DTX) detection to identify at least one interfering user equipment (UE) in the neighboring cell and cancels interference attributable to those identified interfering UEs. The DTX detection and cancelation are then repeated for the remaining neighboring cells in the order they are ranked.
