  • Patent number: 11979760
    Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

  • Patent number: 11936588
    Abstract: Performing UCI multiplexing includes generating PUCCH resources Z at an L1 HP procedure and an L1 LP procedure. The L1 HP procedure and the L1 LP procedure results in a plurality of HP PUCCHs and LP PUCCHs, respectively. A modified procedure for Set Q to resources Z is performed with the plurality of HP PUCCHs and LP PUCCHs as inputs. The plurality of HP PUCCHs according to starting symbols is scanned to identify an earliest starting HP PUCCH. A PUCCH from the plurality of LP PUCCHs or HP PUCCHS that overlaps with the earliest starting HP PUCCH is collected. Inter-L1 priority multiplexing is performed on the earliest starting HP PUCCH and the collected PUCCH, which may result in a new HP PUCCH. The new HP PUCCH is inserted into the Set Q. The modified procedure is repeated until there is no overlap among the HP PUCCHs and the LP PUCCHs.
