  • Publication number: 20190097712
    Abstract: In a radio-access network utilizing beam-formed communications, beam direction for uplink or downlink communications is determined based on learned beam directions applicable to a current location of user equipment (UE) in lieu of a sector scan when prior transmission performance measures are available for the current location. A beam-finding map that associates a plurality of locations with corresponding beam directions previously determined to be operative to direct transmission from those locations to a recipient device is used.

  • Publication number: 20190036552
    Abstract: The present disclosure includes systems and methods for supporting polar codewords with variable polar codeword lengths. Variable codeword length codewords are communicated using an n-bit encoder/n-bit decoder having n inputs and n corresponding outputs. Each input and each corresponding output is associated with a bit index. A set of bit indices to be shortened are selected. The encoder encodes n input bits to obtain n output bits. Each output bit that is associated with a bit index from the set of bit indices to be shortened is ignored. A codeword is generated from all of the remaining output bits.

  • Patent number: 10015786
    Abstract: A technique for receiving and transmitting downlink reference signals is disclosed. When transmitting downlink data demodulation reference signals (DMRS) (or reference signals for downlink data demodulation) by using two or more layers, the DMRS of each layer may be multiplexed by using a code division multiplexing method and then transmitted. The DMRS for each of the two or more layers may be used for one user equipment or for two or more user equipments. And, downlink control signals for transmitting and receiving such DMRS may be configured to have the same format regardless of a single-user mode (or SU-MIMO mode) or a multi-user mode (or MU-MIMO mode), thereby being used.

  • Publication number: 20180176869
    Abstract: In a radio access network, user equipment (UE) is to encode signaling for sector-sweep transmission to a base station via a plurality of directional beams in a millimeter-wave radio band over a random-access shared channel during at least one contention period, and determine a transmission power setting for the directional transmission. The transmission power setting is based on a targeted received signal characteristic to be achieved at the base station using a selected beam direction, and the transmission power setting is determined based on transmission parameters of the UE and reception parameters of the base station, and on channel characteristics. The UE is to initiate transmission of the signaling using the transmission power setting for the plurality of directional beams, wherein the signaling is transmitted to be received according to a targeted received signal characteristic to be achieved at the base station.

    Abstract: Embodiments of a station (STA) and method for communication in accordance with phase noise compensation are generally described herein. The STA may determine, based at least partly on one or more operational parameters, whether to perform phase noise compensation of data symbols of a received protocol data unit (PDU). For instance, the STA may compare the operational parameters with one or more thresholds. The STA may further determine a method of phase noise compensation based at least partly on one or more operational parameters. As an example, the STA may determine a type of interpolation to be used for an interpolation of phase noise estimates of pilot symbols to determine phase noise estimates of data symbols. Example operational parameters may include a signal quality metric, a carrier frequency offset (CFO) measurement and/or modulation and coding scheme (MCS).
