摘要： A computer-readable storage medium stores instructions for execution by one or more processors of a UE to configure the UE for SBFD operation in a 5G NR network, and to cause the UE to decode RRC signaling received from a base station and including at least one CSI-RS resource set with time-frequency resource allocation associated with a CSI-RS transmission. A CSI reporting band is determined with a plurality of PRBs based on the RRC signaling. The CSI reporting band including a subset of the plurality of PRBs associated with one or more DL subband(s) in symbols or slots identified via higher layer signaling or a combination of higher layer and Layer 1 signaling for SBFD operation. Channel measurements are performed based on CSI-RSs transmitted during the CSI-RS transmission. The measurements are associated with the subset of the plurality of PRBs in the CSI reporting band.

摘要： A user equipment (UE) configured for operation in a fifth-generation (5G) new radio (NR) network may perform frequency hopping for physical random access channel (PRACH) repetition for a four-step random access channel (RACH) procedure. The UE may encode a PRACH preamble for multiple PRACH transmissions of the PRACH repetition in accordance with the number of repetitions and each of the multiple PRACH transmissions of the PRACH repetition may be transmitted in accordance with frequency hopping. Each of the multiple PRACH transmissions comprises a same PRACH preamble transmitted in each of a plurality of PRACH occasions.

摘要： The disclosure describes mechanisms for reliability enhancement on control channel and data channel and mechanisms in URLLC. An apparatus of a RAN node for URLLC includes baseband circuitry to configure at least one DCI for scheduling transmission of at least one PDSCH content having same information. For each DCI, the baseband circuitry determines a CORESET for transmitting the DCI. The disclosure further describes mechanisms for the support of low latency transmission in URLLC. To improve peak data rate and spectrum efficiency in FDD system, the RAN node configures a DCI for scheduling data transmission using blank resources of a self-contained slot structure. Further, CBG-based transmission with separate HARQ-ACK feedback is provided to configure a DCI for scheduling data transmission of a TB and to divide the TB into multiple CBGs, and to configure uplink control data to carry separate HARQ feedback for the CBGs.

摘要： Systems and methods of providing a NOMA transmission are described. A UE, may determine, while using grant-free UL NOMA transmission in a slot to a gNB, whether to transmit to the gNB an indication for a grant-based UL NOMA transmission in a later slot. In response to a determination to continue grant-free transmission, if the grant-free transmission comprises repetitions of a TB transmission, a power of the TB transmissions is dependent on a number of repetitions remaining and a total number of repetitions or on higher layer signaling from the gNB. A grant-based transmission request and grant-free UL data are sent to the gNB in the slot if the grant-based transmission is to be used in the later slot, and the repetitions of the TB transmission in accordance with the power are sent if the grant-free transmission is to be used in the later slot.

摘要： 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.

摘要： 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.

摘要： Embodiments of a User Equipment (UE) and methods of communication are generally described herein. If the UE is configured by higher layers to transmit, in a set of symbols of a slot, a sounding reference signal (SRS), a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), or a physical random access channel (PRACH); and if a downlink control information (DCI) format indicates that the UE is to receive, in a subset of the set of symbols of the slot, channel state information reference signals (CSI-RS) or a physical downlink shared channel (PDSCH): the UE may: cancel transmission of the PUCCH, the PUSCH, or the PRACH in remaining symbols from the set of symbols; and may cancel transmission of the SRS in remaining symbols from the subset of symbols.
