  • Publication number: 20210243738
    Abstract: Various embodiments herein provide techniques for cancelation of one or more uplink (UL) transmissions from a user equipment (UE). The UE may receive an indication of a parameter d to use for determining a start of a reference UL resource (RUR). The parameter d may be UE-specific. The UE may further receive a physical downlink control channel (PDCCH) that includes a downlink control information (DCI) to indicate that a UL transmission is to be canceled in a RUR. The UE may determine a starting symbol of the RUR based on the parameter d. In embodiments, the UE may scale the parameter d based on a first subcarrier spacing (SCS) associated with the parameter d and a second SCS associated with the uplink transmission to obtain a scaled parameter d? that is used to determine the starting symbol of the RUR. Other embodiments may be described and claimed.

  • Publication number: 20210226760
    Abstract: A network device such as an evolved NodeB (eNB) or next generation NodeB (gNB) can configure a set of user equipment (UE) for cell reference signal (CRS) muting in order to provide better channel quality and power efficiency in communications. Where an eNB mutes CRS transmissions that are not needed by any UE, an improvement in downlink throughput and reduce connection drop rate can be generated. A CRS muting capability can be determined based on a user equipment (UE) capability information. According to the CRS muting capability of a UE, CRS muting can be generated in a physical channel outside of a narrow band (NB) or a wide band (WB) plus/minus X physical resource blocks (PRBs), wherein X is a non-negative integer, based on the CRS muting capability.

  • Patent number: 11064473
    Abstract: A user equipment (UE) or network device gNB can process or generate downlink control information transmissions for new radio (NR) systems or networks based on a compact DCI format. The DCI can include a grouped broadcast message for reduced signaling overhead that comprises random access response (RAR) message, a paging message, a system information block (SIB) message, another message information type, or any combination thereof. The DCI transmission can be determined as comprising paging information based on a direct indication in a physical downlink control channel (PDCCH) only or both in the PDCCH and a physical downlink shared channel (PDSCH) based on a flag field of the DCI transmission. Other configurations can also further reduce signaling overhead additionally or alternatively.

  • Publication number: 20210212033
    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.

    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.
