Abstract: In an aspect, a base station (BS) transmits, to a user equipment (UE), a downlink control information (DCI) communication that is configured to trigger transmission of an aperiodic (AP) sounding reference signal (SRS). The UE determines a slot offset from the DCI communication to an SRS resource set for the AP SRS based at least in part on an DCI codepoint (i.e., AP SRS resource trigger value) of the DCI communication. The UE transmits the AP SRS on the SRS resource set in accordance with the determined slot offset.

Abstract: According to an aspect, a method for configuring user devices to monitor a downlink control channel includes receiving, by a user device from a base station in a wireless communication system, a signaling message identifying beam information, and determining, by the user device, whether the beam information is associated with at least one adaptive configuration parameter for monitoring a downlink control channel using parameter mapping information, where the parameter mapping information associates adaptive configuration parameters with one or more of a plurality of beam information. The method includes applying the at least one adaptive configuration parameter to configure the user device to monitor a downlink control channel in response to the beam information being determined as associated with the at least one adaptive configuration parameter.

Abstract: A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a radio resource control (RRC) message comprising first information used for indicating a repetition type from a set of repetition types for Physical Uplink Control Channel (PUCCH) transmission(s). The receiving circuitry is also configured to receive an RRC message comprising second information used for indicating a number of PUCCH repetitions or a set of numbers of PUCCH repetitions. Further, the receiving circuitry is also configured to receive, based on a detection of a Physical Downlink Control Channel (PDCCH) carrying a downlink control information (DCI), third information (in the DCI) used for indicating a selection or adjustment of the number of PUCCH repetitions. The UE also includes transmitting circuitry configured to transmit, to the base station, PUCCH transmission(s) according to the first information, the second information, and the third information.

Abstract: A method (200) performed by a UE (102). The method includes receiving (s202) one or more messages for activating at least i) a first set of configured TCI states and ii) a second set of configured TCI states, wherein the first set of activated TCI states is associated with a first PCI and indicates a first set of reference signals, and the second set of activated TCI states is associated with a second PCI and indicates a second set of reference signals. The method also includes performing (s204) beam failure detection, BFD, monitoring. Performing the BFD monitoring comprises: determining (s206) whether a beam failure with respect to the first PCI has occurred based on the first set of reference signals; and determining (s208) whether a beam failure with respect to the second PCI has occurred based on the second set of reference signals.
