Abstract: Technology for user equipment (UE)-specific assigning of demodulation reference signal (DM-RS) sequences to support uplink (UL) coordinated multipoint (CoMP) is disclosed. One method can include a DM-RS sequence assignment device sorting the plurality of UE into a list according to a number of reception point (RP) links for each UE in a CoMP set, and assigning a base DM-RS sequence and a cyclic shift (CS) to a top-ranked UE from the list. The top-ranked UE can have a highest number of RP links. The DM-RS sequence assignment device can repeatedly assign a different CS of the base DM-RS sequence to a plurality of unassigned UE in a same cell as the top-ranked UE, and repeatedly assign the different CS of the base DM-RS sequence to a plurality of unassigned UE in a cooperatively served cell of the top-ranked UE.

Abstract: Embodiments of providing enhanced interference measurements for CSI feedback are generally described herein. In some embodiments, CSI-IM resources are used by UE to perform interference measurements. The serving cell determines a hopping pattern for varying a position of the determined CSI-IM resources in subframes transmitted to the served UE. The determined CSI-IM resources and the determined CSI-IM resources hopping pattern are transmitted to the served UE. The serving node transmits a zero-power (ZP) CSI-RS. The serving node receives an interference measurement from the served UE based on CSI-IM and ZP CSI-RS provided to the served UE from the serving cell. Collisions between the CSI-IM of the serving node and CSI-IM of the non-serving nodes are minimized by the determined CSI-IM resources hopping pattern.

Abstract: This disclosure describes systems, methods, and devices related to collision handling. A device may receive configuration for positioning sounding reference signal (SRS) with transmit (TX) frequency hopping for a positioning SRS transmission, including a switching time for an active bandwidth part (BWP). The device may determine, during a collision between the SRS and another uplink transmission, including the switching time to and from the active bandwidth part, whether to drop one or more SRS symbols. The device may transmit remaining non-colliding symbols of the positioning SRS transmission.

Abstract: 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.

Abstract: 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.

Abstract: Systems for providing prioritization of UL transmissions in a UE are described. The prioritization information is used to resolve resource conflicts among UL transmissions that include conflicts between high priority UL transmissions, between an aperiodic-channel state information transmission and a scheduling request, and between a low priority UL transmission and a high priority UL transmission when timeline conditions for multiplexing in a single UL transmission are not met. The prioritization is based on timing and priority of the UL transmissions to determine which of the UL transmissions to transmit and which to cancel. Additional prioritization is based on reception by the UE of a cancelation index or in an additional overlapping high priority UL grant received in a DCI of a PDCCH that overlaps with at least one other PDCCH associated with the UL transmissions.

Abstract: 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.
