  • Patent number: 12200733
    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.

  • Patent number: 12200732
    Abstract: Systems for providing prioritization of UL transmissions in a UE are described. The prioritization information is used to resolve resource conflicts among UL transmissions that include conflicts between high priority UL transmissions, between an aperiodic-channel state information transmission and a scheduling request, and between a low priority UL transmission and a high priority UL transmission when timeline conditions for multiplexing in a single UL transmission are not met. The prioritization is based on timing and priority of the UL transmissions to determine which of the UL transmissions to transmit and which to cancel. Additional prioritization is based on reception by the UE of a cancelation index or in an additional overlapping high priority UL grant received in a DCI of a PDCCH that overlaps with at least one other PDCCH associated with the UL transmissions.

  • Patent number: 12167409
    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.

  • Patent number: 12150213
    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.
