Abstract: Systems and methods for X in a wireless communication system are provided. A UE may adjust antenna selections and/or antenna switch timing to account for excessive transmission errors due to antenna switching between SRS and PUSCH transmissions. A UE may monitor CRC error rates, and if PUSCH resources next to SRS resources have higher CRC rates above a threshold, the UE may determine if an RSRP difference between the respective antennas is below a threshold. If the RSRP difference is below the threshold, the UE may determine that the antenna port used for SRS may also be used by PUSCH without substantially detrimentally affecting PUSCH. A UE may also determine which SRS resources occurs adjacent to a PUSCH resource most often and assign that SRS resource to a default antenna which may be used for PUSCH transmission. A UE may also adjust antenna switch timing.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device that supports concurrent communications using multiple radio access technologies may receive multiple indications of primary upper power limits for transmitting over multiple primary cells. The wireless device may select a primary cell having a primary upper power limit that is below a threshold. A secondary upper power limit for performing uplink transmission over a secondary cell may be based on the primary upper power limit for the selected primary cell. The wireless device may perform uplink transmissions over the primary cell and the secondary cell in accordance with the primary and secondary upper power limits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may transmit, to a controller, a request to join a platoon. The mobile station may receive, from the controller, a confirmation that the mobile station has joined the platoon. The confirmation may further indicate an assignment of the mobile station to a sub-platoon within the platoon. Accordingly, the mobile station may transmit a handshake to, or receiving a handshake from, a primary anchor device associated with the platoon. The mobile station may additionally transmit a handshake to, or receiving a handshake from, a secondary anchor device associated with the sub-platoon. The sub-platoon may divide and reassemble based at least in part on one or more environmental conditions. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select an antenna for transmitting a New Radio sounding reference signal (SRS) such that antenna resource conflicts with receiving an LTE cell-specific reference signal are minimized based at least in part on an antenna resource configuration. The UE may transmit the SRS on the selected antenna. Numerous other aspects are described.

Abstract: The location of a user equipment may be determined by having the user equipment use a radio carrier and/or a bandwidth part having the highest sub-carrier spacing available to the user equipment. A user equipment may communicate through a plurality of radio carriers, determine a first radio carrier or bandwidth part having a highest sub-carrier spacing, determine a timing advance value associated with the first radio carrier or bandwidth part, and transmit to a location server, the timing advance value.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network in which a base station, such as a gNB or ng-eNB, broadcasts a Positioning Reference Signal (PRS) in a plurality of different directions and at a plurality of different times. A PRS muting configuration is used in which PRS is muted using a time based and angle based pattern to prevent interference between beams transmitted by other base stations and/or to prevent interference between beams transmitted simultaneously by a single base station. The time based and angle based muting pattern, for example, may provide an indication for each direction in the plurality of different directions and for each time in the plurality of different times and as to whether the PRS is transmitted or muted by the base station.

Abstract: A user equipment (UE) is configured to be connected to multiple wireless networks, including e.g., a 5G New Radio (NR) network and an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN). The UE may assign one of the networks with a higher priority for connection. The UE monitors wireless signal metrics to determine if the priority assignment of the networks should be inverted. The UE may monitor the expected data throughput, e.g., determined based on the availability of carrier aggregation, the carrier aggregation order, the multiple in multiple out (MIMO) order, the available bandwidth, E-UTRAN NR—Dual connectivity (ENDC) availability, or quality metrics of wireless signals from one or both wireless networks. The UE may further dynamically select a carrier subscription as the Default Data Subscription (DDS) based on the metrics as well as whether a wireless network associated with a carrier subscription supports ENDC.

Abstract: A user equipment (UE) is configured to be connected to a 5G New Radio (NR) network that shares one or more frequency bands using dynamic spectrum sharing (DSS) with a Long Term Evolution (LTE) network that is transmitting LTE positioning reference signal (PRS). The UE may receive LTE PRS rate matching information from the NR network, such as the LTE PRS configuration data or an LTE PRS rate matching pattern. The UE may decode and process NR data signals and control signals transmitted by the NR network while LTE PRS is transmitted by rate matching around the LTE PRS in accordance with the LTE PRS rate matching information. The LTE PRS muting pattern may be adjusted based on NR data or control signals, and the UE may receive and process NR data and control signals transmitted while the LTE PRS is muted.

Abstract: Bandwidth Parts (BWPs) are used for the transmission and measurement of positioning reference signals during a positioning session. A location server may obtain relevant BWP information, such as the active BWP or a list of configured BWPs, from one or more base stations and/or the user equipment (UE) for the positioning session. The location server may provide assistance data to the UE that is determined based on the BWP information, so that the UE may measure PRS signals from intra-frequency base stations. The location server may further determine a preferred BWP or prohibited BWPs, which may be forwarded to the serving base station to control the BWPs that are used during the positioning session.
