Abstract: In wireless communication systems that support 5G or NR protocols, subframes used for communication may have different numerology options. Numerology options may refer to the characteristics of the subframe such as a tone spacing within each symbol of the subframe, a symbol duration for each symbol of the subframe, a number of symbols in the subframe, etc. A subframe may include a control channel (e.g., the PDCCH) and a data channel (e.g., the PDSCH). In an aspect, the control channel and the data channel within the subframe may have different numerologies. As such, a need exists to signal the numerology of the subframe to users and to determine whether and how to multiplex the control channel and the data channel into the subframe.

Abstract: Wireless communications systems and methods related to providing user interfaces to inform a user of an antenna signal blockage at a wireless communication device are provided. A wireless communication device receives information associated with at least one antenna of the wireless communication device indicating that a signal path of the at least one antenna is at least partially blocked by an object. The wireless communication device outputs, via a user interface of the wireless communication device, an indication that the signal path of the at least one antenna is at least partially blocked.

Abstract: In aspects, an initial access procedure may include a random access channel (RACH) procedure. Thereby, a user equipment (UE) may transmit, to a base station, a random access channel preamble over a first bandwidth of a system bandwidth that is less than the system bandwidth, receive, from the base station after transmitting the random access channel preamble, a random access channel response over the first bandwidth, receive, from the base station after transmitting the random access channel preamble, one or more reference signals over one or more portions of a second bandwidth of the system bandwidth, the second bandwidth being wider than the first bandwidth, the one or more portions of the second bandwidth being different than the first bandwidth, the one or more reference signals being usable for determining a beam to be used for data communication over the second bandwidth, and receive, from the base station, a physical downlink shared channel (PDSCH) over the second bandwidth via the beam based on the one or more reference signals.

Abstract: In aspects, a user equipment may be configured to determine a preconfigured frequency band that is less than an available system bandwidth. The UE may be further configured to perform an initial access procedure with a base station using the preconfigured frequency band. The initial access procedure may include a random access channel (RACH) procedure.

Abstract: repetidores bidirecionais para sistemas de onda milimétrica duplexada por divisão de tempo.métodos, sistemas e dispositivos para comunicações sem fio são descritos. um repetidor sem fio bidirecional pode receber uma primeira forma de onda durante um primeiro período de duplexação de domínio de tempo por meio de um primeiro arranjo de antena e pode transmitir a primeira forma de onda em um segundo arranjo de antena durante o primeiro período de duplexação de domínio de tempo. um comutador bipolar de saída dupla (dpdt) pode ser acoplado ao primeiro e ao segundo arranjos de antenas e pode comutar os arranjos durante um período de guarda entre o primeiro período de duplexação de domínio de tempo e um segundo período de duplexação de domínio de tempo. o comutador dpdt pode alternar o primeiro e o segundo arranjos de antenas entre os modos de transmissão e recepção.

Abstract: Methods, systems, and devices for wireless communications are described. A bidirectional wireless repeater may receive a first waveform during a first time domain duplexing period via a first antenna array and may transmit the first waveform at a second antenna array during the first time domain duplexing period. A di-pole di-throw (DPDT) switch may be coupled to the first and second antenna arrays and may switch the arrays during a guard period between the first time domain duplexing period and a second time domain duplexing period. The DPDT switch may toggle the first and second antenna arrays between transmit and receive modes.
