摘要： The disclosed method and an apparatus are directed to determine an uplink transmission power in in New Radio (NR) systems by a wireless transmit/receive unit (WTRU) for transmitting at least one physical uplink shared channel (PUSCH), using multiple beams toward multiple Tx/Rx points (TRPs). The method includes determining common parameters like a target receive power, a modulation and coding scheme (MCS) specific offset, and a transmit power control (TPC) command parameters common to the multiple beams. The method also includes determining beam-specific parameters like path loss for each beam, a configurable fractional power compensation factor for each beam, and a configurable maximum transmit power level of the each beam, wherein the fractional power compensation factor and the configurable maximum transmit power level for the each beam are determined dynamically or semi-statically based on at least deployment, WTRU mobility, or interference level.

摘要： This application discloses a data transmission method and an apparatus. The method includes: A base station sends configuration information to UE. The UE receives the configuration information, where the configuration information includes an association relationship between a first SRS configuration and one or more PUSCH configurations, and a first BWP in which the first SRS configuration is located is different from a BWP in which each PUSCH configuration is located. The UE sends a first SRS on the first BWP based on the first SRS configuration, and sends a first PUSCH based on a first PUSCH configuration, where the first PUSCH configuration is one of the one or more PUSCH configurations. Correspondingly, the base station receives the first SRS based on the first SRS configuration, and receives the first PUSCH based on the first PUSCH configuration.

摘要： Methods, systems, and devices for user equipment (UE) device-to-device sidelink wireless communications with transmit power adjustments provided through transmit power control requests. A group of UEs may use sidelink groupcast transmissions for communications, and a sidelink groupcast transmitter may increase or decrease transmission power of the groupcast transmissions for more efficient and reliable transmissions. Each UE that receives groupcast transmissions from the sidelink groupcast transmitter may have a different set of wireless resources that may be used to transmit a transmit power control indication to request higher or lower transmit power at the transmitting UE. Alternatively, wireless resources for providing the transmit power indications may be separately provided for TPC-UP indications and for TPC-DOWN indications.

摘要： A terrestrial communication systems, specifically a signal collision avoidance system between a terrestrial transmitter and an airborne receiver, is disclosed. The terrestrial communication system includes an electronic processor configured to determine a receive frequency from a nearby airborne receiver, determine a transmit frequency from a communicatively coupled terrestrial transmitter, and modify the transmit frequency of the terrestrial transmitter based on the determined receive frequency and transmit frequency. To modify the transmit frequency, the electronic processor compares the receive frequency and the transmit frequency to determine a channel type. Based on the determined channel type, including co-channel and adjacent-channel, the electronic processor modifies a spectrum signature of the transmit frequency so that the transmit frequency does not interfere with the receive frequency of the airborne receiver.
