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: Embodiments are presented herein of processors, systems, and methods for performing cellular sidelink communication with flexible resource configuration in a wireless communication system. A first wireless device may receive cellular sidelink resource pool configuration information. The cellular sidelink resource pool configuration information may configure a cellular sidelink resource pool that includes non-contiguous frequency resources. The first wireless device may perform cellular sidelink communication with a second wireless device using the cellular sidelink resource pool that includes non-contiguous frequency resources.

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: A base station may transmit beam indication information to one or more user equipment (UE) devices. For each of a plurality of time units (e.g., symbols) in a time interval (e.g., spanning one or more slots), the beam indication information indicates a corresponding beam that the base station will use to transmit or receive. A UE device may have knowledge of the beam in which it currently resides, e.g., by performing power measurements during a beam scan procedure. Thus, the beam indication information enables the UE to perform transmissions and/or receptions (e.g., configured transmissions and/or receptions) during the appropriate time unit(s). The beam indication information may be dynamically transmitted as part of downlink control information. This transmission may omni-directional, wide beam, or narrow beam. Various schemes of encoding the beam indication information are contemplated.
