Abstract: A method of support of aggressive user equipment (UE) minimum processing times for physical downlink shared channel (PDSCH) processing and physical uplink shared channel (PUSCH) preparation in new radio (NR) is disclosed. The method includes indicating or causing to indicate a capability from the UE to the network in the form of capability reporting for support of Capability 2 processing times, and multiplexing or causing to multiplex scheduling instances with Capabilities 1 or 2 based on the indication. The method also includes applying or causing to apply a relaxation to the minimum UE processing times, N1, indicating time between end of PDSCH to earliest start of corresponding hybrid automatic repeat request-acknowledge (HARQ-ACK) feedback transmission when the PDSCH has specific durations and/or mapping types or has time-domain overlaps with the scheduling physical downlink control channel (PDCCH). A corresponding apparatus and non-transitory computer readable medium are also disclosed.

Abstract: Systems, apparatus, user equipment (UE), evolved node B(eNB), and methods are described for machine-type communications (MTC) with early termination of repeated transmissions. In MTC implementations with narrow bandwidth, significant numbers of retransmissions may be scheduled based on channel quality measurements. If data is successfully decoded at a receiving device while a significant number of retransmissions remain, system resources are wasted. Embodiments described herein thus use downlink control messaging or intermediate hybrid automatic repeat request (HARQ) messaging for early termination of repeated messages.

Abstract: A user equipment (UE) may receive information, via radio resource control (RRC) signaling, regarding a search space of a physical downlink control channel (PDCCH) for obtaining downlink control information (DCI) from a radio access network (RAN) node. Based on a slot format (SF) index in the DCI, the UE may determine a slot format for communicating with the RAN node, and communicate with the RAN node in accordance with the slot format. Additionally, a UE may communicate UE capability information, which may include a maximum number of blind decode attempts (BDAs), to the RAN node. The UE may determine shortened channel control elements (sCCEs) to be used, by the RAN node, to transmit shortened downlink control information (sDCI) via a shortened physical downlink control channel (sPDCCH), obtain sDCI by monitoring the sPDCCH in accordance with the determined sCCEs, and communicate with the RAN node in accordance with the sDCI.

Abstract: Systems, devices, and techniques for indicating the number of repetitions for a downlink control information (DCI) message are described. A described technique includes transmitting an indication of a repetition number for a downlink control information (DCI) message having a predetermined format for transmit power control (TPC) of an uplink channel by a user equipment (UE); and transmitting, to the UE via a machine-type communications physical downlink control channel (MPDCCH), repetitions of the DCI message in accordance with the predetermined format and in accordance with the repetition number. The predetermined format can based on a DCI format 3 or 3A for bandwidth-reduced low-complexity or coverage enhanced (BL/CE) UEs.

Abstract: A method for enhanced physical uplink shared channel (PUSCH) repetitions includes receiving at least one of a dynamic grant or a configured grant for an uplink transmission, determining a time domain resource allocation (TDRA) for repeated transmission of the uplink transmission on a PUSCH, and repeatedly transmitting the uplink transmission based on the TDRA.

Abstract: Methods and systems are provided for communicating in a wireless network based on a prioritization status. User equipment can receive a first signal that includes an indicator. The UE can determine a prioritization status for a second signal based on the prioritization indicator. The UE can communicate, with one or more radio access networks (RANs) of a network, the second signal, where the timeline of the second signal can be out of order respective of other signals communicated by the UE and the wireless network. The second signal can include data transmitted by an ultra-reliable low latency communication (URLLC) service. The UE can communicate the second signal out of order with respect to one or more additional signals. The UE, based on the indicator, can communicate hybrid automated repeat request (HARQ) feedback before a HARQ feedback timeline of a non-urgent transmission.

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.
