Abstract: A first user equipment (UE) is capable of serving as a relay for a second UE using a sidelink connection. The first UE determines that a predetermined condition is satisfied, the predetermined condition associated with the first UE operating as a relay for a second UE, transmits a discovery message and monitors for a signal from the second UE in response to the discovery message.

Abstract: Techniques discussed herein can facilitate inactive state transmissions for a User Equipment (UE) via a 4-step or 2-step inactive state RACH process. One example aspect is a UE device, comprising: communication circuitry; and a processor configured to perform operations comprising: in response to a determination to perform a Radio Resource Control (RRC) inactive data transmission: transmitting, via the communication circuitry, a message 1 (Msg1) or a message A (MsgA) preamble based on a Random Access Channel (RACH) configuration for the RRC inactive data transmission; transmitting, via the communication circuitry a message 3 (Msg3) or a MsgA Physical Uplink Shared Channel (PUSCH) comprising uplink (UL) data via configured resources; and receiving, via the communication circuitry, a message 4 (Msg4) or a message B (MsgB) in response to the Msg3 or the MsgA PUSCH.

Abstract: Systems and methods for sidelink (SL) power control within wireless communication systems are disclosed herein. A user equipment (UE) selects a parameter set to use to calculate a transmit power of one or more channels to be transmitted according to an SL session with a peer UE from a plurality of parameter sets each configured for use according to a distance between the UE and the peer UE. A UE determines whether an SL pathloss based calculation is to be used to calculate a transmit power of a channel according to an SL session with a peer UE, wherein that calculation is configured to be used depending on a distance between the UE and the peer UE. UE selection of a number of physical SL feedback channel (PSFCH) transmissions to match a UE capability and determinations regarding whether to perform PSFCH reception or PSFCH transmission are also discussed.

Abstract: A receiving user equipment (UE) may be configured perform operations relating to sidelink communications with a transmitting UE. The receiving UE may establish a sidelink session with a transmitting UE, perform a local sensing, receive a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), and reserved multiple resources from the transmitting UE, whereby the transmitting UE reserves the reserved multiple resources. The receiving UE determines whether a coordination message is triggered and, in response to the coordination message being triggered, the receiving UE transmits the coordination message to the transmitting UE, the coordination message indicating whether a collision occurs among the reserved multiple resources.

Abstract: Methods and apparatuses are disclosed for configuring full power transmission modes in a UE. The disclosed full power transmission modes include a Mode 0 and a Mode 3, which are enhancements over previous modes disclosed in the 3GPP specification. The UE gathers supported modes and configuration capabilities, such as number of ports and supported coherency schemes, and forwards the configuration capabilities to the network. The network analyzes the received information and selects a supported full power transmission mode based on the UE capabilities. The selection is then transmitted to the UE in a PUSCH-Config message. The UE extracts the selection from the PUSCH-Config message, and configures its radio accordingly.
