  • Publication number: 20250142308
    Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support emergency messaging using a mobile relay. For example, a first user equipment (UE), may transmit a first emergency message indicating a request for relaying a second emergency message to one or more network entities, the first UE being out-of-coverage of a network entity. The first UE may receive, from a second UE associated with an aircraft, a feedback message in response to the first emergency message and may transmit, to the second UE, a second emergency message based on receiving the feedback message. The second UE may receive the second emergency message and transmit, over an air-to-ground wireless communications network, an indication based on the first emergency message and the second emergency message.

  • Patent number: 12289777
    Abstract: Certain aspects of the present disclosure provide techniques for a configurable mode for a response to random access message. A method that may be performed by a user equipment (UE) includes receiving an indication from a base station (BS) that the BS operates according to a first mode in which the BS unicasts a RACH response during a two-step RACH procedure or a second mode in which the BS multicasts the RACH response. The RACH response includes a PDCCH and PDSCH. The UE sends a RACH message to the BS comprising a preamble and payload. The UE monitors and decodes the PDCCH of the RACH response based on the indicated first mode or second mode. The UE decodes the PDSCH of the RACH response and sends feedback to the BS based on the indicated first mode or second mode.

  • Patent number: 12284690
    Abstract: 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.

  • Publication number: 20250126565
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate to the network (e.g., a base station that the UE is communicating with) that the UE is transitioning to an energy harvesting mode, and the network may transmit an indication of a radio resource that is configured for the energy harvesting mode. The UE may communicate with the network via the configured radio resource during the energy harvesting mode. The network may transmit one or more parameters that may trigger the UE to enter the energy harvesting mode. The UE may transmit an indication that the UE is transitioning out of the energy harvesting mode to a normal capability mode, or the UE may transmit an indication that the UE is staying in the energy harvesting mode.

  • Patent number: 12262422
    Abstract: Certain aspects of the present disclosure provide techniques for a hybrid automatic repeat request (HARQ) procedure for the random access channel (RACH) response message in a two-step RACH procedure. A method that may be performed by a user equipment (UE) includes sending a RACH message to a base station (BS) during a two-step RACH procedure. The RACH message includes a RACH preamble and a RACH payload. The UE monitors a RACH response message from the BS during a random access response (RAR) window. The UE transmits a retransmission of the RACH message, an acknowledgement (ACK) to the RACH response message, a negative acknowledgment (NACK) to the RACH response message, or does not transmit, to the BS based on whether a RACH response message carrying a success RAR or a fallback RAR, or no RACH response message, is received from the BS during the window.

  • Patent number: 12262420
    Abstract: Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.
