    Abstract: Systems and methods are configured for receiving configuration data specifying a mapping for physical sidelink shared channel (PSSCH) or physical sidelink control channel (PSCCH) resource blocks to respective candidate physical sidelink feedback channel (PSFCH) resource blocks, the mapping specifying, for a PSSCH or PSCCH transmission, a set of candidate PSFCH resource blocks, the set of candidate PSFCH resource blocks including a common interlace resource block and a set of dedicated resource blocks for PSFCH transmissions; transmitting the PSSCH or PSCCH transmission; and receiving, based on the mapping, a PSFCH transmission from a user equipment (UE), the PSFCH transmission being transmitted using a PSFCH resource block of the set of candidate PSFCH resource blocks.

    Abstract: This disclosure relates to techniques for time division multiplexing sounding reference signal ports in a wireless communication system. A wireless device and a cellular base station may establish a wireless link. The wireless device may be configured to perform a sounding reference signal transmission with time division multiplexing sounding reference signal ports. A maximum transmit power for the wireless device for the sounding reference signal transmission may be determined based at least in part on the time division multiplexing sounding reference signal ports. A transmit power may be selected for the sounding reference signal transmission based at least in part on the maximum transmit power for the wireless device for the sounding reference signal transmission. The sounding reference signal transmission may be performed using the selected transmit power.

    Abstract: A wireless communication network schedules multiple components carriers on a same frequency band to user equipment (UE) for transmitting wireless signals. The network may indicate to the UE when to use each carrier, and the UE my switch between transmitting on each carrier. The UE may transmit multiple different signals on each carrier. In particular, the UE may include a local oscillator (LO) that generates a first frequency of a first carrier, and couple the LO to the transmission paths when transmitting using the first carrier. The UE may then cause the LO to generate a second of a second carrier, and couple the LO to the transmission paths when transmitting using the second carrier. Additionally or alternatively, the UE may include a second LO that generates the second frequency, and couple the second LO to the transmission paths when transmitting using the second carrier.

    Abstract: A system may include an access point (AP), user equipment (UE), and a reconfigurable intelligent surface (RIS). The RIS may include an array of elements coupled to adjustable devices controlled to cause the array to reflect signals in different directions. The RIS may be controlled in a first mode in which the AP controls the adjustable devices, a second mode in which the UE controls the adjustable devices, and a third mode in which the RIS controls the adjustable devices. The RIS, AP, or UE may determine which mode to place the RIS in based on a downlink signal transmitted by the AP, an uplink signal transmitted by the UE, measurements of the signals performed on the RIS, a first distance or round trip time between the AP and the RIS, and/or a second distance or round trip time between the UE and the RIS.
