Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

Abstract: This disclosure relates to techniques for opportunistically depowering receiver chains of a wireless device. Based on control information, a device may determine whether the current number of active receiver chains can be reduced while maintaining a target achievable code rate for a period of data reception associated with the control information. Additionally, the device may generate and use a lookup table to determine whether to depower receiver chains, and which receiver chains to depower.

Abstract: Apparatuses, systems, and methods for a wireless device to perform simultaneous uplink activity for multiple RATs in the same carrier using multiplexing at a layer above the physical layer. The wireless device may establish wireless links with first and second base stations, respectively, according to first and second radio access technologies (RATs), respectively. The first base station may provide a first cell operating in a first system bandwidth and the second base station may provide a second cell operating in a second system bandwidth. The wireless device may determine whether inter-RAT uplink coexistence in the same frequency band is enabled. If so, the wireless device may perform uplink activity for both the first RAT and the second RAT in the first system bandwidth by multiplexing uplink data for the first RAT and uplink data for the second RAT at a layer above the physical layer.

Abstract: In an example method, a user equipment (UE) device determines one or more component carriers available to the UE device for at least one of transmitting or receiving data over a wireless network. The UE device transmits, to the wireless network, for each component carrier, an indication whether the component carrier supports at least one of transmitting or receiving data according to a multi-transmission and receiving points (multi-TRP) communication protocol.

Abstract: A user equipment (UE) configured to determine a resource selection window which identifies a first set (e.g., a total set) of candidate resources. The UE may then remove one or more candidate resources from the first set of candidate resources in response to receiving sidelink control information (SCI) from a pedestrian UE with a reservation of the one or more first candidate resources. After removal of these candidate resources from the initial or first set based on their presumed unavailability, the result may be a second set of candidate resources, which may be a subset of the initial or first set for use in communicating with a third UE. The UE may also be configured to remove candidate resources based on a reference signal receive power (RSRP) threshold which can also be adjusted based on a maximum value or a highest priority of the pedestrian UE's data.

Abstract: A cell receives channel state information for multiple transmission reception points (TRPs) from a user equipment (UE). The cell selects a first transmission reception point (TRP) of multiple TRPs associated with a cell of a network, transmits a signal to a user equipment (UE) via the selected TRP, wherein the signal is configured to trigger semi-persistent CSI (SP-CSI) report at the UE and receives the SP-CSI report from the UE that includes CSI corresponding to each TRP of the multiple TRPs.

Abstract: Reporting capabilities regarding Cross Carrier Scheduling (CCS) with different Sub-Carrier Spacing (SCS) may include generating a message to send to a base station. The message may comprise an indication of a user equipment's (UE's) capability for CCS with different SCS. Based on the UE's capability for CCS with different SCS, a number of unicast downlink control information (DCI) per physical downlink control channel (PDCCH) monitoring occasion per span may be processed to determine scheduled resources for downlink (DL) and uplink (UL) signaling or channels. The DL and UL signaling or channels may be processed using the scheduled resources.
