  • Patent number: 10868772
    Abstract: Systems, apparatuses, and methods for control signaling of beam failure detection are disclosed. A beam pair link may be comprised of multiple bandwidth parts (BWPs) or component carriers (CCs). In one embodiment, a beam failure detection reference signal (BFD RS) may be configured, with subsequent BFD RS instances defining a BFD RS periodicity. A BFD periodicity for monitoring the BFD RS may be configured to be less than, or equal or greater than the BFD RS periodicity. A beam failure may be declared if a minimum number of BFD RS instances, either within the BFD periodicity, or nearest the BFD periodicity if no instances fall within the BFD periodicity, fall below a predetermined threshold. The BFD periodicity and BFD RS may be configured for all BWPs/CCs, a subset of BWPs/CCs, or each individual BWP/CC.

  • Publication number: 20200389897
    Abstract: Systems and methods for transmission of PDSCH and HARQ-ACK feedback in 5G networks are described. The TDRA of PDSCH repetitions are indicated in a DCI by a SLIV sequence configuration that contains multiple SLIV sequences. Each SLIV sequence for a slot is associated with an independent repetition factor and may also be associated with a partition factor to indicate a partition within the slot. One or more TRPs may be used to transmit each PDSCH repetition. The TCI states are mapped to the PDSCH repetitions in a round-robin fashion using an offset in terms of number of PDSCH repetitions from where TCI state switching starts and a number of consecutive PDSCH repetitions per TCI state. The HARQ-ACK bits in response to the PDSCH from the TRPs are concatenated in order of increasing control resource set higher layer signaling index.
