Abstract: Methods, systems, and devices for wireless communication are described to provide priority traffic grant-less access to pre-defined communication resources that are semi-persistently scheduled. A set of semi-persistent communication resources may be reserved for use by priority traffic. If the semi-persistent resources are not used for priority traffic, the semi-persistent resources may be scheduled for use by other types of traffic. As priority traffic is identified, the priority traffic may be transmitted using the semi-persistent resource without having those communication resources granted by a scheduling entity. Such grant-less access to the semi-persistent resources may result in collisions between the scheduled traffic and the priority traffic. To mitigate interference between different traffic types, the scheduled traffic may be transmitted using a transmission power that ensures an interference parameter indicative of an amount of interference imposed by the scheduled traffic on the priority traffic satisfies an interference threshold.

Abstract: Methods, systems, and devices for wireless communications are described that provide beam determination in beamformed wireless communications. A base station may transmit multiple repetitions of control information for a subsequent scheduled transmission. A user equipment (UE) may receive one of the multiple repetitions, determine the control information, and adjust beamforming parameters for the scheduled transmission. The UE may have a scheduling threshold that corresponds to a time needed for the UE to adjust beamforming parameters for the scheduled transmission, and the UE may identify the beamforming parameters for the scheduled transmission from any one of the multiple repetitions of control information, which may be transmitted using different downlink transmission beams, before or after the scheduling threshold, or combinations thereof.

Abstract: Various aspects of the disclosure relate to communicating control information via interleaved symbols. For example, symbols of a first handshaking process may be interleaved with symbols of a second handshaking process. In some scenarios, the control information includes request-to-send (RTS) and clear-to-send (CTS) signaling. In some aspects, different tone spacing is used for the control information than is used for data within a subframe. In some aspects, a different cyclic prefix length is used for control information than is used for data within a subframe.

Abstract: Wireless communications systems and methods related to mitigation of calibration errors are provided. A base station (BS) transmits, via an antenna array including a plurality of antenna elements, a first communication signal using a first number of the plurality of antenna elements and a first transmission power level to a user equipment (UE). The BS receives from at least one UE, a measurement report based on the first communication signal. The BS transmitting a second communication signal using a second number of the plurality of antenna elements and a second transmission power level based on the one or more measurement reports. At least one of the first number of the plurality of antenna elements is different from the second number of the plurality of antenna elements, or the first transmission power level is different from the second transmission power level. Other aspects and features are also claimed and described.

Abstract: Various aspects of the disclosure relate to power control for independent links. For example, power control at a device may be based on transmissions on multiple 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). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, power control for the first device may be based on power control commands received on multiple links. In some scenarios, a power control constraint may be met taking into account the transmission power on multiple links.

Abstract: Method and apparatus are provided for reporting and receiving actual UL transmission power. In accordance with some implementation, a UE may send a first indication of power headroom to a base station. The UE may receive one or more resources allocation for a UL transmission. The UE then may determine actual transmission power to be used in the UL transmission. Upon determination, the UE may transmit the UL transmission and send an indication of the actual transmission power to the base station. The base station, in response to receiving an indication of actual transmission power of the first UL transmission, may adjust an estimate of the link quality based on the receive indication of actual transmission power.

Abstract: A method for position determination based on carrier-phase measurements is disclosed. The method comprises receiving one or more downlink signals transmitted from a base station (BS) during a downlink period, wherein the downlink signals are modulated using a downlink carrier wave, measuring, during the downlink period, a first carrier phase associated with the downlink carrier wave, estimating, during an uplink period subsequent to the downlink period, an integer ambiguity (IA) change, and measuring, during a later downlink period subsequent to the uplink period, a second carrier phase based on the resolved first carrier phase and the estimated IA change.

During an initial access stage, the base station may set different transmission rates for different transmission directions, and may transmit initial access signals based on the transmission rates in the different transmission directions The apparatus may be a base station. The base station determines transmission rates for a plurality of transmission directions, where each transmission rate is determined for a respective transmission direction of the plurality of transmission directions. The base station transmits at least one initial access signal in each of one or more of the plurality of transmission directions based on a corresponding transmission rate of the transmission rates.
