Abstract: Sidelink pathloss between a remote user equipment device (UE) and a relay UE may be determined based at least on transmit power information provided by the relay UE to the remote UE. The remote UE may receive, via a sidelink discovery signal from the relay UE, a message that includes first information representative of a transmit power of the relay UE and/or second information representative of a measured receive signal power of a sidelink solicitation signal previously transmitted by the remote UE and received by the relay UE. The remote UE may determine a sidelink pathloss between the remote UE and the relay UE based at least on the first information and/or the second information. The remote UE may select/reselect a relay UE based on corresponding pathlosses determined for the respective paths between the remote UE and different respective relay UEs.

Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, to inform and/or request the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station (BS) may receive from a user equipment (UE) a first buffer status report (BSR) indicating an amount of uplink data buffered by the UE for transmission to the BS, and may subsequently receive 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 received prior to expiration of a timer authorizing transmission of a second BSR following the first BSR. In response, the BS may allocate resources for transmission to the UE, based on the first BSR and the first BSR update message. The BS may provide an uplink grant identifying the allocated resources.

Abstract: Determining priority of a simultaneous sidelink (SL) transmission and uplink (UL) transmission of a user equipment (UE) within a 5G New Radio (NR) network may comprise processing an SL control information (SCI) corresponding to at least one of a SL hybrid automatic repeat request (HARQ) or an SL schedule request (SR) included in a UL transmission to be sent by a UE to thereby determine a priority value associated with the at least one SL HARQ or SL SR. An SCI of an SL transmission to be sent by the UE simultaneously with the UL transmission may be processed to thereby determine a priority value associated with the SL transmission. The priority value of the at least one SL HARQ or SL SR may be compared to the priority value of the SL transmission. Transmissions may then be prioritized based on the comparison of priority values.

Abstract: A base station may operate in a context where the propagation delay between the base station and user equipment (UE) devices is large. The base station configures UE devices with a common delay. The base station receives a random access preamble from a UE device. The base station determines a time slot in which the random access preamble was transmitted, based on a configured correspondence between allowable time slots and subsets of an available set of preambles. The base station computes a Random Access Radio Network Temporary Identifier (RA-RNTI) based on parameter values including an index, of the determined time slot. The base station employs the computed RA-RNTI to address a random access response for the UE device.

Abstract: Apparatuses, systems, and methods for radio resource management (RRM) signal reception. A user equipment device (UE) may receive, via a first reception path, an RRM related signal and receive, via a second reception path, a non-RRM related signal that may be multiplexed with the RRM related signal onto a symbol. The first reception path may be a first antenna port of an antenna panel or a first antenna panel of the UE and the second reception path may be a second antenna port of the antenna panel or a second antenna panel of the UE. The RRM related signal may include a reference signal for RRM. and may be included in a non-zero power (NZP) interference measurement.

Abstract: This disclosure relates to apparatuses and methods for providing and managing reception feedback for multicast and broadcast services (MBS). A base station (BS) may select and communicate, to a group of user equipment devices (UEs), configuration parameters for MBS communications, such as an indication of an MBS retransmission procedure for an MBS service. The BS may also transmit, to the group of UEs, an MBS data communication. A first UE may receive the MBS data communication, but may determine that the received MBS data communication is corrupted. The first UE may respond by transmitting, to the BS, a negative-acknowledgement (NACK) message. The BS may retransmit the MBS data communication either as an MBS transmission or as a unicast transmission, based on the configuration parameters. The first UE may monitor the appropriate resources to receive the retransmitted MBS data communication, based on the configuration parameters.
