摘要： Over-the-air (OTA) phase synchronization for reciprocity-based coordinated multipoint (CoMP) joint transmission is disclosed. Phase synchronization reference signals (PSRS) are transmitted within a CoMP operation that can be used to determine the phase drifts of the transmit and receive chains of the base stations. These phase drifts can then be used to obtain a relative phase drift between the uplink and downlink channels. When estimating the uplink channel from the sounding reference signals (SRS), the relative phase drift may be applied to estimate the downlink channel as well. The OTA phase synchronization may be performed with a user equipment (UE)-assisted or inter-base station procedures.

摘要： Methods, systems, and devices for wireless communication are described. A wireless communications system may support techniques for using non-staggered reference signals to increase the efficiency of the system and reduce the complexity of channel estimation. A base station may schedule a transmission to a user equipment (UE) including pilot tones mapped to a first symbol and a second symbol. In some cases, the pilot tones on the first and second symbols may be non-contiguous, and the base station may scramble the pilot tones on the first and second symbols according to the same scrambling sequence. In other cases, the pilot tones on the first and second symbols may be contiguous, and the pilot tones may be scrambled according to the same or different scrambling sequences. These techniques may result in reduced complexity for interference estimation and channel estimation at a UE.

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： Efficient cell-specific reference signal (CRS) and control channel configurations may be established dynamically based on channel conditions for one or more user equipment (UE) that may be served by a transmission. A base station may configure a CRS for a transmission time interval (TTI) based at least in part on a channel quality of one or more UEs that are to receive transmissions during the TTI. A number of downlink symbols at the beginning of the TTI may be used for CRS transmissions, and UEs with better channel quality may receive CRS transmissions and other control information in a first symbol, while UEs with a poorer channel quality may receive higher power CRS transmissions in the first symbol and the other control information is transmitted in a subsequent symbol.

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.
