摘要： Aspects of the present disclosure enable determination of a transmit beamformer used for data transmission. The determination of the transmit beam is based on beamformed reference signals (e.g., CSI-RS, SSB) transmitted by the transmitter, such as a base station, and received by the receiver, such as a UE. The receiver feeds back information based on an angle of arrival (AoA) of the beamformed reference signal to help the transmitter determine a transmit beamformer used by the transmitter to transmitter data to the receiver. In some embodiments, the feedback information may include a projection of an angle of arrival at the receiver of a propagation path have a strongest measures reference signal on a receive beamformer. In some embodiments, the feedback information may include a beamformer to be used at the transmitter, that has been determined at the receiver.

摘要： Embodiments are provided for traffic scheduling based on user equipment (UE) in wireless networks. A location prediction-based network scheduler (NS) interfaces with a traffic engineering (TE) function to enable location-prediction-based routing for UE traffic. The NS obtains location prediction information for a UE for a next time window comprising a plurality of next time slots, and obtains available network resource prediction for the next time slots. The NS then determines, for each of the next time slots, a weight value as a priority parameter for forwarding data to the UE, in accordance with the location prediction information and the available network resource prediction. The result for the first time slot is then forwarded from the NS to the TE function, which optimizes, for the first time slot, the weight value with a route and data for forwarding the data to the UE.

摘要： Historical decoding in accordance with signal interference cancellation (SIC) or joint processing may reduce the amount of data that is re-transported across a network following an unsuccessful attempt to decode a data transmission. In one example, historical decoding is performed in accordance with interference cancellation by communicating information related to interfering data (rather than information related to serving data) following a served receiver's unsuccessful attempt to decode an interference signal. The information related to the interfering data may be the information bits carried by the earlier interfering data transmission or parity information (e.g., forward error correction (FEC) bits, etc.) related to the earlier interfering data transmission.

摘要： Historical decoding can be performed in accordance with pilot signal retransmission or control information retransmission to reduce the amount network resources consumed during data recovery. In one example, historical decoding is achieved through retransmitting a sub-set of coded bits carried by an earlier transmission, which are compared with a corresponding portion of the original signal (stored in memory) to obtain improved channel state information (CSI) relating to that earlier transmission. In another example, historical decoding is achieved through communicating parity information related to a sub-set of the coded bits carried by an earlier transmission, which are used in accordance with a data aided CSI technique to obtain the improved CSI relating to that earlier transmission. In yet another example, historical decoding is achieved by re-transmitting control information carried by an earlier transmission, which is used to decode an original signal (stored in memory).
