    Abstract: DM-RS symbols may be inserted in the beginning of a subframe, or in two parts of the subframe. In one aspect, a method, a computer-readable medium, and an apparatus for dynamically conveying DM-RS information are provided. The apparatus may be a base station. The apparatus may determine the number of DM-RS symbols and/or the locations within a subframe for transmission of the DM-RS symbols. The apparatus may transmit the number of the DM-RS symbols and/or the locations within the subframe for transmission of the DM-RS symbols to a UE. In another aspect, a UE may receive the number of DM-RS symbols and/or the locations within a subframe for transmission of the DM-RS symbols from a base station. The UE may decode the DM-RS symbols from the subframe based on the number of the DM-RS symbols and/or the locations within a subframe for transmission of the DM-RS symbols.

    IPC: H04W74/08

    Abstract: Methods, systems, and devices for wireless communications are described that support different, or adjusted, random access channel (RACH) preamble formats for efficient use of shared RACH time-frequency resources. The described techniques provide for assigning different RACH preamble formats to wireless devices that have a higher link budget, whereupon the devices may transmit the different RACH preamble using the link budget available to them in one or more RACH transmission opportunities in the shared RACH time-frequency resources. Such methods, systems, and devices may allow for more RACH transmission opportunities, as well as less interference between RACH transmissions. For example, wireless devices communicating over a backhaul network may have a higher link budget than wireless devices communicating over an access network. As such, RACH preambles transmitted by the wireless devices communicating over the backhaul network may be shorter than RACH preambles transmitted by the wireless devices communicating over the access network.

    IPC: H04W72/12

    Abstract: A UE may receive a directional synchronization subframe from a base station and transmit a scheduling request to the base station during a time period based on the directional synchronization subframe. The scheduling request may enable a base station to grant the UE resources to send a buffer status report (BSR). The time period may be associated with a random access channel (RACH) time period. The UE may also transmit a scheduling request within a frequency region of the RACH time period. The scheduling request may be transmitted based on a received indication of a set of subcarrier, a cyclic shift, or a sequence index. In some examples, the resources used by the UE to send the BSR may include physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) resources.

    Abstract: Certain aspects of the present disclosure provide techniques for reporting of a beam correspondence state. Certain aspects provide a method for wireless communication by a first wireless device. The method includes, based on detecting the occurrence of a triggering event, determining one or more beam correspondence states for one or more beams or portions of beams used by the first wireless device for communication. The method further includes transmitting one or more indications of the one or more beam correspondence states to a second wireless device, wherein the one or more indications of the one or more beam correspondence states indicate whether the first wireless device has the capability of beam correspondence between the one or more beams and corresponding one or more transmit or receive beams used by the first wireless device for communication.

    IPC: H04W76/28

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit (or a base station may receive) a beam failure recovery (BFR) request based at least in part on detecting a beam failure while the user equipment is in a discontinuous reception (DRX) mode; and the user equipment may receive (or the base station may transmit) a response to the BFR request, wherein the response uses a particular structure based at least in part on the beam failure occurring during the DRX mode. Numerous other aspects are provided.

    Abstract: Certain aspects of the present disclosure provide techniques communicating in a wireless network. In one embodiment, a method includes monitoring for a paging downlink control channel comprising downlink control information, wherein the downlink control information comprises a first short message; processing the first short message; determining if the control information further comprises scheduling information; processing the scheduling information if the downlink control information comprises scheduling information and the UE is not in a connected state; and ignoring the scheduling information if the downlink control information comprises scheduling information and the UE is in a connected state.

    Abstract: Un procedimiento (1600, 1900, 2000) para la comunicación inalámbrica, que comprende, en un dispositivo: transmitir (1605, 1905, 2005) una primera señal de acceso aleatorio a una primera potencia de transmisión durante un primer período de tiempo asociado con una primera dirección de haz; determinar (1610, 1910, 2010) que no se ha recibido una respuesta de acceso aleatorio a la primera señal de acceso aleatorio; identificar una segunda dirección de haz, preferente, en base, al menos en parte, a un período de acceso aleatorio más temprano para las direcciones de haz disponibles; seleccionar (1615, 1915, 2015) una segunda potencia de transmisión mayor que la primera potencia de transmisión si la segunda dirección de haz es la misma que la primera dirección de haz, pero seleccionar una segunda potencia de transmisión no menor que la primera potencia de transmisión si la segunda dirección de haz es diferente de la primera dirección de haz, y; transmitir (1620, 1920, 2020) una segunda señal de acceso aleatorio usando la segunda potencia de transmisión y la segunda dirección de haz durante un segundo período de tiempo.
