  • Patent number: 11736253
    Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical down-link control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCH. The DM-RS can be detected within the slot, the DM-RS starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.

  • Patent number: 11711813
    Abstract: Embodiments described herein relate to downlink (DL) control channel signaling for an aperiodic channel state information (A-CSI) trigger. In one example, a user equipment (UE) communicates with a network to receive first configuration signaling to identify a first downlink control information (DCI) in a physical downlink control channel (PDCCH). The UE also receives, from the network, the first DCI. The first DCI is appended with cyclic redundancy check (CRC) bits that are scrambled by a common radio network temporary identifier (RNTI) and is to indicate an aperiodic channel state information (A-CSI) trigger. Next, the UE receives, from the network, channel state information (CSI) reference signals in one or more occasions that follow an occasion in which the first DCI is received and generates and transmits a CSI report in a physical uplink control channel (PUCCH) based on the CSI reference signals.

  • Patent number: 11700672
    Abstract: Systems and methods for PDCCH monitoring in NR systems. The UE provides to a serving cell UE capability information indicating a capability of the UE to monitor PDCCH. The UE capability information indicates a carrier aggregation capability larger than multiple serving cells and has a maximum number indication for a maximum number of PDCCH candidates that the UE can monitor per span. The serving cell transmits an RRC message to a UE in response to the UE capacity information. The RRC message has a per-slot and/or per-span indication to monitor PDCCHs on the serving cell for a maximum number of PDCCH candidates and non-overlapping CCEs. The UE monitors PDCCH candidates and, in the event that a span contains larger than a maximum number of PDCCH candidates or non-overlapping CCEs across multiple served cells, determines whether to monitor a particular PDCCH candidate in the span.

  • Patent number: 11683145
    Abstract: Embodiments of dynamic multiplexing are described, including the transmission of preemption indication (PI) to indicate preemption of time-frequency resources. In some embodiments, a next Generation NodeB (gNB) is configured to transmit PIs in signaling to preempt an enhanced Mobile Broadband (eMBB) communications transmission with an ultra-reliable and low latency communications (URLCC) transmission. In some embodiments, a user equipment (UE) is configured to monitor a region of time-frequency resources, within a bandwidth part (BWP), for a PI. The PI indicates to the UE a portion of time-frequency resources that omit transmissions intended for the UE. In some embodiments, the gNB transmits the PI to the UE within preemption indication downlink control information (PI-DCI) in a physical downlink control channel (PDCCH) in a control resource set (CORESET). In some embodiments, the BWP is defined according to a frequency domain location, a bandwidth, and a subcarrier spacing for a given numerology.

  • Patent number: 11678278
    Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.
