Abstract: A user equipment (UE) comprising a processor configured to perform the operations that determines an uplink (UL) slot is described. In exemplary embodiments, the UE receives, from a base station, a scaling factor through a first Radio Resource Control (RRC) signal. The UE may further determines an offset through a second RRC signal. In addition, the UE may receive from the base station, downlink control information (DCI) that includes an indication of an initial time gap. Furthermore, the UE may calculate a new time gap by at least applying the scaling factor to the initial time gap and determine a slot of uplink transmission based on at least the new time gap and the offset.

Abstract: Systems, methods and circuitries are provided for performing UE autonomous selection in a vehicle-to-anything (V2X) communication environment, that includes one or more processors configured to schedule resources for discontinuous periodic transmission having a scheduled discontinuous time period in which scheduled resources are not transmitted. The one or more processors are further configured to perform a monitoring operation at the scheduled discontinuous time period, the monitoring operation comprising a monitoring for a collision of scheduled resources of the evaluating UE with scheduled resources of a competing UE, and selectively perform a corrective action when a collision of scheduled resources of the evaluating UE with scheduled resources of the competing UE is detected during the monitoring operation.

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A user equipment device (UE) may transmit to a base station (BS) a first buffer status report (BSR) indicating an amount of uplink data buffered by the UE for transmission to the BS, and may subsequently transmit to the BS a first BSR update message indicating that an additional amount of uplink data has been buffered by the UE subsequent to transmission of the first BSR. The first BSR update message may be transmitted prior to expiration of a timer authorizing transmission of a second BSR following the first BSR. The UE may receive from the BS an uplink grant allocating resources for transmission of at least a portion of the uplink data buffered by the UE. The uplink grant may have a size based on the first BSR and the first BSR update message.

Abstract: An evaluating user equipment (UE) includes memory and one or more processors communicatively coupled to the memory. The one or more processor are configured to schedule periodic resources with one or more configured feedback-based collision detection parameters, and perform a periodic transmission to one or more receiving UEs. The one or more processors are also configured to collect negative acknowledgement (NACK) statistics for the periodic transmission according to the configured feedback-based collision detection parameters, and selectively perform corrective action based on the collected NACK statistics and at least one of the configured feedback-based collision detection parameters.

Abstract: A base station associated with a wireless communication system is disclosed. The base station comprises one or more processors configured to generate a service configuration signal to be provided to a user equipment (UE) associated therewith. In some embodiments, the service configuration signal comprises an indication of one or more service configurations associated with a data transmission that are allowed to be transmitted by the UE during an INACTIVE state of the UE. In some embodiments, the one or more processors is further configured to provide the service configuration signal to the UE.

Abstract: A user equipment (UE) may operate on a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier. The UE identifies a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier corresponding to a primary secondary cell (PSCell) of a secondary cell group (SCG) for dual connectivity (DC), determines that the dormant BWP is configured in an active state and performing one or more actions corresponding to the dormant BWP.

The BS may provide an uplink grant identifying the allocated resources.

Abstract: A user equipment (UE) may transmit hybrid automatic repeat request (HARQ) feedback when part of a group of UEs. The UE receives a radio network temporary identifier (RNTI) associated with a group of UEs that includes the UE. The UE monitors for a signal from one of a cell on which the UE is currently camped or a cell to which the UE is currently connected that is scrambled by the RNTI and includes control information. The UE transmits HARQ feedback to the one of the currently camped cell or currently connected cell, the HARQ feedback associated with the signal and, when the signal is received, performs an operation in response to the control information.

Abstract: Methods and systems to enhance NR RACH procedure to accommodate non-terrestrial networks (NTN) are disclosed. The length of the RAR window may be extended. In one aspect, a gNB of the NTN may perform blind retransmissions of the RAR message scheduled by DCI within the RAR window to user equipment to improve transmission reliability of the RAR message for NTN. The number of blind retransmission and the transmission pattern may depend on the PRACH reception condition, an uplink channel condition, or may be pre-configured. In one aspect, the gNB may extend the K1 value and K2 value that determine the delays between uplink and downlink transmissions to align the time domain duplex (TDD) uplink-downlink configuration due to the long propagation delays associated with the NTN. In one aspect, the gNB may broadcast or multicast RAR window size extension values to the UEs based on the orbital altitude of the satellites.

Abstract: A user equipment (UE) is configured to operate as a relay UE between a remote UE and a base station. The relay UE receives, from an originating device, a data packet for relay to a recipient device, determines that the relay of the data packet to the recipient device has failed and sends, to the originating device, a transmiss ion including the data packet, wherein the transmission comprises an indication that the data packet is being returned to the originating device.
