Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

Abstract: In order to overcome problems that a UE may face in determining CORESETs and beams for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL relationships, UL resources, and/or spatial relationships are selected for a COT. A UE receives an indication of a set of CORESETs selected from a plurality of CORESETs or a set of QCL relationships selected from a plurality of QCL relationships. The UE determines the set of CORESETs from the plurality of CORESETs or the set of QCL relationships from the plurality of QCL relationships based on the indication received. A UE receives an indication of a set of UL resources or a set of spatial relations. The UE determines the set of UL resources or the set of spatial relations based on the indication received.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive downlink control information corresponding to a transmission of a transport block over a plurality of transmission time intervals (TTIs). The wireless device may identify a redundancy version sequence for the transport block. The redundancy version may be a pre-defined sequence or may be configured by higher layer signaling based on sequence criterion. The wireless device may transmit or receive a plurality of redundancy versions of the transport block in the plurality of TTIs based at least in part on the redundancy version sequence. In some examples, the plurality of redundancy versions may be determined based at least in part on a starting redundancy version identified by another wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a resource grant for a data communication within a transmission time interval (TTI). The UE may receive, from the base station, an indication of a control signal configuration and an end symbol index associated with the resource grant. The UE may identify, based at least in part on the received indication, a plurality of symbol positions in the TTI in which reference signals are to be communicated in conjunction with the data communication.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for code rate selection for control channels. An exemplary method generally includes selecting, from a set of code rates, a code rate to be used to encode a stream of bits using a polar code, based on at least one of a downlink control channel aggregation size, an uplink control channel assignment, or a payload size of the stream of bits, encoding the stream of bits using the polar code and the selected code rate, and transmitting the encoded stream of bits.

Abstract: manuseio de erro em mudança automática de enlace ativo duplo. trata-se de métodos, sistemas e dispositivos para comunicações sem fio. em alguns sistemas, um equipamento de usuário (ue) pode realizar um procedimento de mudança automática de enlace ativo duplo de uma estação-base fonte para uma estação-base alvo. durante o procedimento de mudança automática de enlace ativo, o ue pode ter conexões com ambas as estações-base simultaneamente. em tais casos, as oportunidades de transmissão par se comunicar com as estações-base podem conflitar. para lidar com as oportunidades de transmissão conflitantes, o ue pode descartar uma ocasião de monitoramento ou um recebimento de pacote para uma estação-base com base nas regras de priorização. em alguns casos, para mitigar perdas de pacote, a estação-base pode configurar retransmissões ou agregação de partição para fornecer ao ue oportunidades adicionais para receber um pacote. adicional ou alternativamente, o ue pode transmitir uma mensagem de notificação para uma estação-base que indica ocasiões de monitoramento ou pacotes descartados.

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

Abstract: Various embodiments include methods, components and wireless devices configured to provide physical layer security in a communication system. In various embodiments, a wireless device processor may receive a first signature from a base station. The wireless device processor may determine a second signature based on the first signature. The wireless device processor may receive from the base station a communication that has been modified using a second signature determined by the base station. The wireless device processor may perform a matching operation to determine whether its second signature matches the second signature used to modify the base station communication. The wireless device processor may enable communications with the base station in response to determining that the second signature determined by its processor matches the second signature used to modify the communication.
