Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for multi-transmission reception point (TRP) reception, the processing circuitry is to decode radio resource control (RRC) signaling. The RRC signaling includes configuration information configuring a plurality of transmission configuration indication (TCI) states. A media access control (MAC) control element (CE) is decoded, where the MAC CE indicates multiple active TCI states of the configured plurality of TCI states. Multiple received beams are determined using the multiple active TCI states. Downlink information is decoded, where the downlink information originates from multiple TRPs and is received via the determined multiple receive beams associated with the multiple active TCI states.

Abstract: A method for enhanced physical downlink control channel monitoring (PDCCH) includes determining a monitoring span for monitoring a PDCCH within a slot, the monitoring span having a start symbol and a duration that spans one or more symbols within the slot. At least one of a maximum number of blind decoding (BD) attempts or a maximum number of control channel elements (CCEs) for channel estimation is determined based on the monitoring span. The PDCCH is monitored within the monitoring span up to the at least one of the maximum number of BD attempts or the maximum number of CCEs.

Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.

Abstract: Systems, devices, and techniques for transmit power control (TPC) in wireless communication systems are described. A described technique performed by a user equipment (UE) includes receiving downlink control information (DCI) messages corresponding to respective physical uplink shared channel (PUSCH) transmission occasions; determining power control adjustment states for the PUSCH transmission occasions; and transmitting in the PUSCH transmission occasions in accordance with the power control adjustment states. Determining the power control adjustment states can include selectively applying TPC accumulation. Determining the power control adjustment states can include determining whether a first PUSCH transmission occasion occurs out-of-order with respect to a second PUSCH transmission occasion based on an arrival ordering of the DCI messages, where the first PUSCH transmission occasion occurs before the second PUSCH transmission occasion.

Abstract: In an example computer-implemented method, a user equipment (UE) receives first configuration data including an indication of a search space set for monitoring a wireless network for an uplink cancellation command, and second configuration including an indication to activate monitoring of the wireless network for an uplink cancellation command. The UE further receives a first physical downlink control channel (PDCCH) including scheduling information for an uplink transmission. The UE monitors the wireless communications network for the uplink cancellation command in accordance with the search space set, and receives a second PDCCH from the wireless including the uplink cancellation command, where the uplink cancellation command includes an indication to cancel a first portion of the uplink transmission. The UE cancels a transmission of the first portion of the uplink transmission.

Abstract: Technology is disclosed for a user equipment (UE) operable for wake-up signal (WUS) communication in a fifth generation (5G) new radio (NR) network. The UE can be configured to: identify a resource set for a WUS with a repetition level, wherein: the resource set for the WUS includes a mapping of the WUS that associates the WUS with one or more physical resource blocks and one or more orthogonal frequency division multiplexing (OFDM) symbols, and the repetition level identifies a number of base sequences for the WUS in the resource set; and switch to a network access mode (NAM) from a power saving mode (PSM) based on a detection of the WUS in the resource set.
