Abstract: RESUMEN La presente divulgación proporciona sistemas, métodos y aparatos para comunicación inalámbrica. En un aspecto, se proporciona un enfoque de multi-punto de transmisión-recepción (TRP) para retroalimentación de acuse de recibo (ACK) de solicitud de repetición automática híbrida (HARQ) usando indicadores de asignación de enlace descendente (DAI) de contador (cDAI) y DAI totales (tDAI). Por ejemplo, algunas técnicas y aparatos descritos en la presente pueden proporcionar un método de conteo conjunto en donde los cDAI y tDAI se implementan y se rastrean de manera conjunta entre los TRP de un grupo multi-TRP. Esto puede ser útil en el caso de retorno ideal cuando el grupo multi-TRP se programa de manera conjunta, y puede ser más robusta contra errores que un método de conteo separado. Algunas técnicas y aparatos descritos en la presente pueden proporcionar un método de conteo separado, en donde los cDAI y tDAI se implementan y rastrean por separado mediante los TRP respectivos de un grupo multi-TRP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a plurality of downlink grants for a corresponding plurality of data transmissions, wherein each downlink grant identifies resources for receiving the corresponding data transmission and indicates whether the corresponding data transmission comprises a last data transmission for a reporting occasion. The UE may determine, based at least in part on the received downlink grants, that a last downlink grant for the last data transmission associated with the reporting occasion was not received. The UE may transmit a feedback report during the reporting occasion, wherein a format of the feedback report is based at least in part on the last downlink grant for the last data transmission not being received.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first hybrid automatic repeat request (HARQ) process identifier set associated with a first configured scheduling process and may determine a second HARQ process identifier set associated with a second configured scheduling process. The UE may assign an HARQ process identifier, included in the first HARQ process identifier set, to a process instance associated with the first configured scheduling process and may assign an HARQ process identifier, included in the second HARQ process identifier set, to a process instance associated with the second configured scheduling process. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may indicate time and frequency resources for a low latency physical downlink control channel (sPDCCH), which may be different from another physical downlink control channel (PDCCH), to a user equipment (UE). The base station may then transmit a common sPDCCH (CsPDCCH) message to indicate which low latency control channel elements (sCCEs) are used for sPDCCH transmission during a given subframe. In some cases, the signaling used to indicate the initial resource allocation for sPDCCH may be infrequent relative to the CsPDCCH transmissions. If some of the resources initially allocated for sPDCCH are not actually used for sPDCCH during a subframe, the base station and the UE may use those resources for communicating data. For example, the base station may transmit data using a low latency physical downlink shared channel (sPDSCH) to the UE using those resources.

Abstract: Certain aspects of the present disclosure provide techniques for utilizing and processing repeated DCI transmissions that schedule common uplink or downlink transmissions. The techniques allow a UE to decide which repeated DCI to use for determining resources for the uplink or downlink transmissions.

Abstract: Un procedimiento para comunicación inalámbrica realizado mediante un equipo de usuario, UE, comprendiendo el procedimiento: identificar (1305) una longitud de una señal de relleno basada, al menos en parte, en una longitud máxima permitida de la señal de relleno configurada por una estación base; transmitir (1310) la señal de relleno de la longitud identificada para reservar el acceso a una banda de espectro de radiofrecuencia compartida, RF, con la señal de relleno transmitida durante un espacio de transmisión que ocurre entre una transmisión de enlace descendente, DL, y una transmisión de enlace ascendente, UL, en dúplex por división de tiempo, TDD; y transmitir (1315) la transmisión UL en la banda de espectro de RF compartida reservada después de la transmisión de la señal de relleno.

Abstract: RESUMEN Para superar los problemas que puede enfrentar un UE al determinar un haz predeterminado para la comunicación con la estación base durante un COT, se proporcionan un método, un aparato y un medio legible por computadora para que una estación base indique al UE qué CORESET, supuestos de QCL, recursos de UL y/o relaciones espaciales se seleccionan para un COT. Un UE recibe, desde una estación base, una indicación correspondiente a un COT. La indicación es para al menos uno de un conjunto de CORESET, un conjunto de supuestos de QCL, un conjunto de recursos de UL o un conjunto de relaciones espaciales para determinar un haz predeterminado. El UE determina el haz predeterminado de la estación base para su uso durante el COT en función de la indicación. El UE transmite o recibe una transmisión mediante el uso del haz predeterminado.

Abstract: Wireless communications systems and methods related to communications in a network that supports data transmitted in an unlicensed frequency band and a licensed frequency band are provided. A first wireless communication device communicates, with a second wireless communication device, a configuration indicating a first resource in an unlicensed frequency band and a second resource in a licensed band. The first wireless communication device communicates, with the second wireless communication device in the unlicensed frequency band, a first communication signal based on the configuration. The first wireless communication device communicates with the second wireless communication device in the licensed frequency band, a second communication signal based on at least one of a channel status of the unlicensed frequency band or a transmission parameter associated with at least one of the first communication signal or the second communication signal.
