  • Publication number: 20240023117
    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.

  • Publication number: 20240014995
    Abstract: A generation Node B (gNB) configured for Sub-Band Full Duplex (SBFD) communication in a fifth-generation new radio (5G NR) network may communicate with two or more User Equipment (UEs) during SBFD symbols. During any one or more of the SBFD symbols, a downlink transmission may be transmitted to at least one of the UEs simultaneously with reception of an uplink transmission from at least another of the UEs. The SBFD symbols may span the carrier bandwidth and may comprise at least a downlink (DL) subband and an uplink (UL) subband within the carrier bandwidth. To communicate with the two or more UE simultaneously during the SBFD symbols, the gNB may configure the UEs that are to transmit during one or more of the SBFD symbols with timing-advance offset information to be used by the UEs to adjust a configured timing-advance for initiating an uplink transmission relative to downlink symbol timing at a UE within the one or more SBFD symbols.

  • Publication number: 20240008047
    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.

  • Publication number: 20230422172
    Abstract: Various embodiments herein provide techniques for a low power wake-up signal (LP-WUS) with two parts. The LP-WUS may be received by a wake-up receiver of a user equipment (UE) and used to trigger a main receiver of the UE to wake up (e.g., turn on or enter a higher power state). The first part may be used to indicate the presence and/or other characteristics of the second part. The first and second parts may each be transmitted in one or more symbols, slots, or time resource units. Other embodiments may be described and claimed.

  • Publication number: 20230413335
    Abstract: An apparatus and system are described for power control transmission for multiple physical random access channel (PRACH) transmissions. The systems include repetition level ramping for the PRACH transmissions, as well as power control mechanisms for PRACH transmissions that use identical transmission (Tx) beams and that use different Tx beams. The number of repetition attempts for a PRACH transmission increases when a random access response (RAR) is not received or does not pass contention resolution for a maximum number of attempts. A PRACH transmission within one or more transmission occasions is cancelled if the power exceeds a maximum power for PRACH transmissions.

  • Patent number: 11849413
    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.

  • Patent number: 11838892
    Abstract: Systems and methods of reducing power consumption associated with paging or cDRX mode are described. A wake-up receiver (WUR) wakes up from an idle mode or cDRX state. Whether a wake-up signal (WUS) has been received by the WUR is determined. The WUS is a low-complexity signal that is less complicated than a PDCCH or PDSCH and is repeated multiple times at resource elements as indicated in a configuration from an eNB. If received, a baseband transceiver wakes up for reception of a PDCCH for the UE in a PO when the UE is in the idle mode or a PDSCH for the UE when the UE is in the cDRX state.

The UE can transition from the RRC connected state to the RRC idle state. The UE can encode data packets for transmission over a PUSCH to the eNodeB using the CG PUSCH resources while the low mobility UE is in the RRC idle state.

  • Patent number: 11792630
    Abstract: Embodiments of a User Equipment (UE), generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive a narrowband physical downlink control channel (NPDCCH) that includes an uplink scheduling parameter. The UE may determine an uplink scheduling delay for transmission of a narrowband physical uplink shared channel (NPUSCH) in accordance with time-division duplexing (TDD). The uplink scheduling delay may be based on a sum of a predetermined first number of subframes and a variable second number of subframes. The second number of subframes may be based on a window of variable size that starts when the first number of subframes has elapsed since reception of the NPDCCH, and ends when a number of uplink subframes has elapsed since the start of the window. The number of uplink subframes may be indicated by the uplink scheduling parameter.

  • Patent number: 11792814
    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.
