摘要： Methods, systems, and devices for wireless communications are described. The described techniques provide for the configuration and operation of a multi-hop relay at different layers to enable a remote user equipment (UE) to act as a relay for a client UE that may be out of coverage of a network. For example, a network relay UE may establish a communication link with the network, and the network relay UE may transmit, to a remote UE, a relay configuration that authorizes the remote UE as a multi-hop relay to provide a connection to the network for one or more other UEs. The remote UE may transmit an acknowledgement to the network relay UE in response to receiving the relay configuration, and the remote UE may then transmit a relay discovery message including multi-hop relay information based on receiving the relay configuration.

摘要： In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for receiving, by a relay user equipment (UE) from a remote UE, a remote UE radio resource control (RRC) message for establishing a relayed communication between the remote UE and a network entity via the relay UE; determining, by the relay UE, remote UE information associated with the remote UE for establishing a remote UE communication context between the relay UE and the network entity based on the remote UE RRC message; and transmitting, by the relay UE to the network entity, the remote UE RRC message and the remote UE information.

摘要： Methods, systems, and devices for wireless communications are described to support relayed sidelink communications. A first device and a base station may communicate via a communication link including a sidelink link between the first device and a second device and a relay link between the second device and the base station. The base station may determine restrictions for the communication link and transmit an indication of the restrictions over the relay link. The restrictions may differentiate data originating from the first device and the second device, restrict the first device to one or more resources, or associate logical channels at the first device with one or more transport block sizes and communication links. The second device may relay the indication of the restrictions to the first device. The first device, the second device, and the base station may communicate over the communication link according to the restrictions.

摘要： Certain aspects of the present disclosure are directed to a method for wireless communication. The method generally includes receiving a message for dual-active-protocol stack (DAPs) handover (HO) from a source network entity to a target network entity, wherein carrier-aggregation (CA) is configured with the source network entity prior to reception of the message for HO, deactivating the CA in response to reception of the message for handover (HO) to activate a single carrier mode with the source network entity, and performing the HO from the source network entity to the target network entity during a HO period, wherein the single carrier mode is maintained with the source network entity during at least a portion of the HO period, and wherein connection with the target network entity is maintained during the at least the portion of the HO period.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) to be scheduled by a scheduler UE in a sidelink system may transmit a first scheduling request (SR) to request sidelink resources. The UE may transmit the first SR via a set of feedback resources. The scheduler UE may transmit, to the UE, a sidelink control message to schedule a sidelink transmission. The sidelink control message may indicate a set of feedback resources mapped to the sidelink transmission. The UE may transmit the scheduled sidelink transmission based on the sidelink control message and may request additional sidelink resources. The UE may transmit a second SR, where the second SR is transmitted via the set of feedback resources mapped to the sidelink transmission.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may provide a session request associated with establishing a proximity services (ProSe) session. The session request may include ProSe session specific information including information that indicates a ProSe service type associated with the ProSe session. The user equipment may receive a session establishment response after providing the session request. The session establishment response may include at least one of a ProSe session authorization indication associated with the UE, or ProSe policy information for the ProSe service type associated with the ProSe session. Numerous other aspects are provided.

摘要： Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for maintaining simultaneous connection with a network in dual-active protocol stack (DAPS) handover (HO), such as, for example, in packet data convergence protocol (PDCP) duplication applications that require a user equipment (UE) to maintain up to four simultaneous connections with the network, such as in an multi-radio access transfer (RAT) dual connectivity (MR-DC) to MR-DC HO. In some embodiments, the UE is configured during various phases of a DAPS HO. In some other embodiments, the UE may be configured for multi-TRP operations.

摘要： Methods, systems, and devices for wireless communications are described. One example method for wireless communications at a user equipment (UE) includes detecting a radio link failure (RLF) condition for a connection between the UE and a network over a first cell group and determining, in response to detecting the RLF condition, whether an air interface resource allocation is available for a signaling radio bearer (SRB) between the UE and the network over another cell group. The method also includes selecting, based at least in part on the determination, one of a plurality of RLF procedures. In some examples, the UE may select a first RLF procedure that fully releases radio resources when no SRB is available and a different, second RLF procedure that partially when an SRB is available between the UE and the network over a second cell group.

摘要： Techniques are described herein for signaling procedures that use a hierarchical mobility, which may be applied when a user equipment (UE) is operating in a radio resource control (RRC) inactive state or the RRC idle state. A wireless communication system may be configured with a plurality of areas in which one or more networks are established for communicating certain types of signals. Examples of the areas associated with networks may include a tracking area (TA), a radio access network area code (RAN-AC), a radio access network based notification area (RNA). A synchronization signal or a paging signal may be transmitted using a first set of communication resources in a first area, while the synchronization signal or the paging signal may be transmitted using a second set of communication resources in a second area different than the first set of communication resources.
