摘要： Methods, systems, and devices for wireless communications are described. In accordance with the described techniques, communicating devices (e.g., an encoder and decoder) may apply an orthogonal cover code to a polar codeword to reduce cross-correlation between different codewords. For example, such techniques may reduce power consumption at a decoding device by providing for earlier decoding termination (e.g., as a result of the reduced cross-correlation). Techniques for generating the cover codes (e.g., on a per-aggregation level basis) and applying the cover codes (e.g., within a search space) are described. Additionally or alternatively, the described techniques may relate to seeding of reference signals used to support decoding of the codewords. Improved orthogonality between reference signal seeds may further suppress codeword recipient ambiguity.

摘要： A method, apparatus, and computer-readable medium at a transmitting network device or a target network device in a listen-before-talk (LBT) session that employ a spatial LBT procedure is disclosed. The spatial LBT procedure takes into account multiple-input multiple-output (MIMO) configuration information in measuring an effective interference. Accordingly, the spatial LBT procedure enables the transmitting network device or the target network device to more accurately measure an interference and make a more accurate decision on whether a channel is clear, and thus improves the system-wide performance. Also, the spatial LBT procedure allows the transmitting network device or the target/receiving network device to adaptively adjust the LBT power detection threshold when the MIMO configuration is not available. This also enables the network devices to more accurately measure interference and make a more accurate decision on whether the channel is clear, especially when advanced MIMO technologies are deployed in 5G or beyond.

摘要： Reference signal and transmitter (Tx)/receiver (Rx) precoding for user equipment (UE) multiplexing in new radio (NR) shared spectrum networks is discussed. In certain reference signals, a base station may schedule multiple UEs for transmission of uplink reference signals within an identified subframe. The base station may transmit a reference signal configuration message, wherein the reference signal configuration message includes a transmission sequence identifier identifying a multiplexing for antenna ports assigned for transmission of the uplink reference signals. The multiplexing may be one or both of frequency divisional multiplexing (FDM) and time division multiplexing (TDM) over the identified subframe. Additional reference signals, transmit precoders may be identified by the base station based on channel inversion calculations of the channel matrix determined based on uplink reference signals.

摘要： Wireless communications systems and methods related to over-the-air uplink-downlink (UL-DL) reciprocity calibration. A central unit transmits downlink (DL) calibration reference signal (RS) and a calibration request. The central unit receives, in response to the calibration request, a first uplink (UL) calibration RS and a first DL channel estimate associated with a first transmission point (TP) and a first wireless communication device. The central unit transmits a DL coordinated multipoint (CoMP) joint transmission signal according to an uplink-downlink (UL-DL) reciprocity calibration. The UL-DL reciprocity calibration is based on at least a first UL channel estimate based on the first UL calibration RS, the first DL channel estimate, a second UL channel estimate associated with a second TP and the first wireless communication device, and a second DL channel estimate associated with the second TP and the first wireless communication device.

摘要： Certain aspects of the present disclosure provide techniques for protecting overhead and common channel transmissions in a NR shared spectrum system. A BS of a first operator may receive information regarding at least one overhead transmission associated with a wireless device of a second operator and may protect one or more overhead signal transmissions of the wireless device based, at least in part, on the received information. A UE may detect information associated with at least one overhead transmission from a wireless device associated with a first operator and may transmit the information regarding the detected overhead transmission to a BS associated with a second operator. A UE served by a BS associated with a first operator may detect a wireless device (e.g., another UE or a BS) associated with a second operator. The UE may report an identification of the wireless device to the BS.

摘要： Various aspects of the disclosure relate to controlling allocations for independent links. For example, a device may dynamically control the uplink/downlink allocations for different links. In some aspects, the independent links may involve a first device ( e.g. , a user equipment) communicating via different independent links with different devices ( e.g. , transmit receive points (TRPs) or sets of TRPs). At least one device may signal the uplink/downlink allocation for the different links. If the isolation between links is high, the links may use different time division duplexed (TDD) or frequency division duplexed (FDD) subframe structures. If the isolation is low or for certain types of information ( e.g. , control information), the direction of transmission for one link may be constrained to be the same as the direction of transmission for another link ( e.g. , the links may use the same TDD/FDD frame structures). Also, sounding on different links may be time division multiplexed.

摘要： Methods, systems, and devices for wireless communication are described that provide for detection and management of hidden node interference. A user equipment (UE) may provide measurement reports to a serving transmitting device to help identify the hidden node interferer in response to detecting hidden node interference. The serving transmitting device may collaborate with one or more neighboring transmitting devices, such as other transmitting devices of an operator of a wireless communications system, to identify one or more of the neighboring transmitting devices that are within an energy detect or preamble detect radius of the hidden node. The serving transmitting device may coordinate with the neighboring transmitting device(s) to determine when the hidden node may transmit, to transmit coordinated preamble transmissions to prevent the hidden node from transmitting during a transmission, or to identify a modulation and coding scheme for the transmission.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) or base station communicating in an unlicensed radio frequency spectrum band may transmit a signal (e.g., a request-to-send (RTS) or clear-to-send (CTS) signal) in a licensed radio frequency spectrum band to decrease the likelihood that neighboring devices will transmit interfering communications. Specific resources may be designated in the licensed radio frequency spectrum band for transmitting these signals, and these resources may be associated with specific unlicensed channels. Signaling in the licensed radio frequency spectrum band may also carry an indication of the unlicensed channel being used or other information relevant to the unlicensed communication. The RTS/CTS signaling in licensed radio frequency spectrum band may be transmitted during a downlink transmit opportunity or an uplink transmit opportunity, or both. Different energy detection thresholds may apply to RTS/CTS signals in licensed and unlicensed spectrum.
