Abstract: Certain embodiments are directed to a system and method of physical uplink shared channel (PUSCH) transmission termination. The system and method can include a user equipment (UE) that can receives a downlink control information (DCI) scheduling a PUSCH transmission overlapped with repetitions of a hybrid automatic repeat request (HARQ) process for the UE and terminates the PUSCH transmission upon detection of the DCI after a fixed number of symbols where the fixed number of symbols is counted from a symbol after the last symbol of a control resource set (CORESET).

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: 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: 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.

Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of physical downlink control channel (PDCCH) monitoring in different search spaces sets independently from one another in order to manage different services optimally. A processor of the network device can be configured to receive physical downlink control channel (PDCCH) candidates of a PDCCH in a slot for channel estimation across search spaces of the slot. Different priorities can be determined among the PDCCH candidates in the slot based on a priority rule. Then a number of PDCCH candidates can be skipped/dropped from monitoring based on the different priorities of the PDCCH candidates to ensure that a threshold level of blind decoding operations across a plurality of slots of the PDCCH is being satisfied. The UE can monitor a portion of the PDCCH candidates while concurrently skipping another.

Abstract: Systems and methods are described for wake-up signaling of user equipment (UE). The systems and methods can include at least generating, by the BS, a wake up signal (WUS), wherein the WUS includes a length-131 Zadoff-Chu (ZC) sequence and a Gold sequence for radio equipment-level (RE-level) scrambling, and transmitting, by the BS, the WUS to a user equipment (UE) in a paging group associated with the WUS.

Abstract: Systems, devices, and techniques for antenna port configuration in wireless communication systems are described. A described technique performed by a user equipment (UE) includes receiving configuration information that determines a bit-width value for an antenna port indication field of a downlink control information (DCI) format; receiving a DCI message that is in accordance with the DCI format; and determining an antenna port configuration for one or more demodulation reference signals based on the DCI message, the configuration information, and the bit-width value.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for use in a wireless network for dynamic indication of soft resource availability. Some embodiments are directed to an apparatus in an Integrated Access and Backhaul (IAB) node. The apparatus includes processor circuitry and radio front circuitry. The radio front end circuitry can be configured to receive, from a second IAB node, a slot format indicator (SFI). The SFI can include a slot format entry including a soft symbol indicating availability of a soft resource. The processor circuitry can be configured to use the slot format entry to communicate with a third IAB node, different from the second IAB node, using the soft resource as indicated by the soft symbol.

Abstract: Disclosed herein are timing determination techniques for 5G radio access network (RAN) cells. According to various such techniques, during a random access procedure, a user equipment (UE) may receive a grant of resources for an uplink (UL) data transmission in a random access response (RAR) message. The UE may identify a scheduled slot for the UL data transmission based on a received slot of the RAR message and an applicable slot offset value. The applicable slot offset value may indicate a number of slots by which the received slot precedes the scheduled slot. The applicable slot offset value may be identified using the various techniques described herein.
