摘要： Some techniques and apparatuses described herein provide an indication of a result of decoding a two-step random access channel (RACH) message and an action to be performed by a user equipment (UE). For example, some techniques and apparatuses described herein may provide the indication using a UE contention resolution identity-based approach, wherein the contention resolution identity of the UE may be provided in a random access response. Some techniques and apparatuses described herein may use a fallback indicator that indicates the result of decoding and/or the action to be performed. Some techniques and apparatuses described herein may use a random access response (RAR) subheader that selectively omits a random access preamble identifier based at least in part on the result of decoding and/or the action to be performed.

摘要： Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

摘要： Disclosed are techniques for wireless communication. In an aspect, a packet data convergence protocol (PDCP) entity of a receiver device receives, from a radio link control (RLC) entity of the receiver device, a plurality of RLC data packets received from a transmitter device over an RLC unacknowledged mode (UM) data radio bearer (DRB) or RLC transparent mode (TM) DRB. The PDCP entity generates a plurality of PDCP data packets corresponding to the plurality of RLC data packets. The receiver device determines to send a PDCP status report indicating a reception status at the receiver device of the plurality of PDCP data packets and transmits the PDCP status report to a PDCP entity of the transmitter device. The receiver device receives, in response to sending the PDCP status report, one or more PDCP data packets of the plurality of PDCP data packets that were not successfully received at the receiver device.

摘要： Aspects of the disclosure provide control-plane signaling to support a user equipment (UE)-assisted local caching feature, where information content may be locally cached at or near a base station in a wireless communication network. The control plane signaling may include a system information broadcast (SIB) to advertise availability of the feature; a UE capability message that indicates UE support of the feature; and/or radio resource control (RRC) configuration signaling to configure the UE to utilize the feature. Further aspects describe operation and maintenance (OAM) configuration of a base station to utilize the feature. A base station may additionally check for UE eligibility to utilize the feature, e.g., based on the user's subscription. In further examples, various enhancements to the user-plane signaling to utilize the UE-assisted local caching feature are provided. Other aspects, embodiments, and features are also claimed and described.

摘要： An apparatus for wireless communication, including a memory and at least one processor coupled to the memory. The at least one processor is configured to receive a pre-allocation resource for a target cell via a handover command and transmit a physical layer acknowledgment based on a target cell downlink packet. The at least one processor is also configured to receive an indication for a communication with the target cell in response to the physical layer acknowledgement and access the target cell using the pre-allocated resource based on the indication for the communication with the target cell.

摘要： Disclosed are techniques for wireless positioning performed by a user equipment. For example, the method includes entering into a Radio Resource Control (RRC) inactive state. The method includes monitoring, during a first time interval, while the user equipment is in the RRC inactive state, one or more first bandwidth parts having a first bandwidth to perform a first operation. The method includes monitoring, during a second time interval, while the user equipment is in the RRC inactive state, one or more second bandwidth parts having a second bandwidth to perform a second operation. The second bandwidth is different than the second bandwidth.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network, a list of serving cells including a first serving cell that is using a control resource set (CORESET) for single frequency network (SFN) transmissions. Additionally, the UE may receive, from the network, a control element indicating two transmission configuration indicator (TCI) states and associated with the first serving cell and the CORESET. Accordingly, the UE may process the control element based at least in part on determining that one or more additional serving cells in the list are not using the CORESET for SFN transmissions. Numerous other aspects are described.

摘要： A method of wireless communication by a user equipment (UE) in a non-terrestrial network (NTN) includes transmitting a first small data transmission to a base station during a first transmission occasion associated with a first NTN beam, while the UE remains in an inactive mode or idle mode. The method further includes identifying a switch from the first NTN beam to a second NTN beam. The method still further includes transmitting a subsequent small data transmission to the base station during a second transmission occasion associated with the second NTN beam.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a beam failure detection (BED) reference signal set in one or more slots in a full-duplex mode and in one or more slots in a half-duplex mode. The UE may detect beam failure due to self-interference based at least in part on a comparison of measurements of the BFD reference signal set in the full-duplex mode and half-duplex mode. The UE may switch from the full-duplex mode to the half-duplex mode for slots configured for the full-duplex mode based at least in part on detecting beam failure due to self-interference. Numerous other aspects are described.
