Abstract: The present disclosure provides communication apparatuses and communication methods for optimising time domain window and demodulation reference signal (DMRS) for joint channel estimation. The communication apparatuses include a communication apparatus comprising: circuitry which, in operation, determines one or more time domain windows for multiple physical uplink shared channel (PUSCH) transmissions, each length of the one or more time domain windows being not more than an overall length of the multiple PUSCH transmissions; and a transmitter, which in operation, transmits reference signals based on the one or more time domain windows.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify one or more antenna groups at the UE, each of the one or more antenna groups comprising two or more antenna ports and associated with group-based sounding reference signal transmission. The UE may receive an indication of a sounding reference signal configuration identifying one or more resources for performing group-based sounding reference signal transmissions using at least one of the one or more antenna groups. The UE may transmit one or more sounding reference signals using the one or more resources and at least one antenna port from the at least one of the one or more antenna groups.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message identifying a frequency hop configuration that configures the UE to use frequency hopping when transmitting repetitions of an uplink shared channel transmission. The UE, the base station, or both may determine, based on the UE being configured with the frequency hop configuration, a frequency hop for each repetition of the uplink shared channel transmission. Each frequency hop may be determined based on a corresponding uplink shared channel index for a respective repetition a frequency hop for each repetition of the uplink shared channel transmission. The uplink shared channel index may be an uplink transmission occasion index, or a repetition index. The UE may transmit the repetitions of the uplink shared channel transmission using respective frequency hops in accordance with the determination and the frequency hop configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a first signal is associated with a New Radio Unlicensed (NR-U) Light configuration; determine a frequency hopping (FH) pattern and a set of FH channels for a second signal based at least in part on the determination that the first signal is associated with the NR-U Light configuration; and receive the second signal based at least in part on the FH pattern and the set of FH channels. Numerous other aspects are provided.

Abstract: A sensor device includes processing circuitry configured to output, at a first bandwidth, first bandwidth data to a hub device using a first wireless connection configured for a first wireless protocol. In response to determining that the sensor device has second bandwidth data to output to the hub device at a second bandwidth, the processing circuitry is configured to output a second wireless connection request to the hub device using the first wireless connection. In response to the hub device outputting information for establishing a second wireless connection with the sensor device, the processing circuitry is configured to establish the second wireless connection for a second wireless protocol different from the first wireless protocol. The processing circuitry is configured to output, at the second bandwidth, the second bandwidth data to the hub device using the second wireless connection. The second bandwidth is greater than the first bandwidth.
