Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.

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: 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: Systems, devices, and techniques for adjusting a user equipment (UE) processing time parameter in a wireless communication system that include transmission and reception points (TRPs) are described. A described technique performed by UE includes receiving a first physical downlink shared channel (PDSCH) from a first TRP corresponding to a first scheduling physical downlink control channel (PDCCH) and a second PDSCH from a second TRP corresponding to a second scheduling PDCCH. The technique further includes transmitting a first hybrid automatic repeat request acknowledgement (HARQ-ACK) message and a second HARQ-ACK message based on the first PDSCH and the second PDSCH in accordance with a first processing time parameter and a second processing time parameter, respectively. The first processing time parameter can be based on a PDSCH mapping type, a processing capability of the UE, and one or more timing characteristics of the first PDSCH and the second PDSCH.

Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical down-in link control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of e OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCH. The DM-RS can be detected within the slot, the DM-RS starting at a symbol 01 location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the
PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.

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.

The method includes signaling an enhanced processing time capability and fallback type to the wireless network, wherein the processing time capability includes respective numbers of transport blocks per slot the UE can process mapped to different respective specified numbers of serving cells. A number of configured serving cells that support the enhanced processing time capability is determined. The method includes determining, based on the number of configured serving cells, a maximum number of transport blocks per slot that will be communicated between the UE and the configured serving cells. A fallback behavior based on the determined maximum number of transport blocks per slot and the fallback type is determined.

Abstract: Methods and architectures for establishing an uplink control channel in a fifth generation (5G) or new radio (NR) wireless network includes transmitting scheduling requests (SRs) at sub-slot level/symbol-level periodicities and determining whether SR transmit opportunities will collide with downlink (DL) signals being received and halting an SR transmission if the timing of DL symbols overlap at an OFDM symbol with the SR transmission.
