    Abstract: According to an aspect of the disclosure, a base station may convey the parameter information to the UE based on selection of particular resources to be used for transmission of synchronization signals, where the selected resources correspond to the particular parameter information. The UE may blindly detect the synchronization signals on various candidate resources and determine the parameter information based on the resources where the synchronization signals are detected. The apparatus may be a base station. In an aspect, the base station determines parameter information of one or more parameters. The base station selects, based on the parameter information, synchronization resources from a plurality of candidate resources for transmission of one or more synchronization signals, where the selected synchronization resources correspond to the parameter information. The base station transmits the one or more synchronization signals using the selected synchronization resources.

    Abstract: Un método de comunicación inalámbrica, que comprende: identificar (1305, 1405) un primer haz de transmisión de enlace ascendente y/o un primer recurso de acceso aleatorio para un procedimiento de acceso aleatorio; transmitir (1310, 1410), a una estación base, un mensaje de acceso aleatorio usando el primer haz de transmisión de enlace ascendente y/o el primer recurso de acceso aleatorio; seleccionar (1315, 1415) un segundo haz de transmisión de enlace ascendente y/o un segundo recurso de acceso aleatorio basándose, al menos en parte, en una ausencia de una respuesta de acceso aleatorio desde la estación base correspondiente al mensaje de acceso aleatorio transmitido usando el primer haz de transmisión de enlace ascendente y/o el primer recurso de acceso aleatorio; determinar (1320, 1420) una potencia de transmisión de enlace ascendente basándose, al menos en parte, en la selección del segundo haz de transmisión de enlace ascendente y/o el segundo recurso de acceso aleatorio; y retransmitir (1325, 1425) el mensaje de acceso aleatorio a la estación base usando el segundo haz de transmisión de enlace ascendente y/o el segundo recurso de acceso aleatorio y la potencia de transmisión de enlace ascendente determinada; comprendiendo adicionalmente el método: recibir múltiples señales de sincronización direccional desde una estación base, y determinar una estimación de pérdida de trayectoria para cada una de las múltiples señales de sincronización direccional, en donde el segundo haz de transmisión de enlace ascendente y/o el segundo recurso de acceso aleatorio se seleccionan basándose, al menos en parte, en las estimaciones de pérdida de trayectoria determinadas.

    Abstract: A first apparatus may communicate with a user equipment (UE) through an active beam. The first apparatus may transmit, to the UE, information indicating a periodicity at which control information is to be communicated on a control channel through a control-information beam. The first apparatus may communicate, with the UE, the control information on the control channel through the control-information beam at the periodicity. Further, the first apparatus may receive a request to change the active beam, which may indicate a beam index corresponding to a second beam, and the first apparatus may change the active beam to the second beam corresponding to the beam index indicated by the request.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a downlink (DL) signal from a base station on one or more DL beam(s). The UE may identify of a nature of correspondence between one or more receive beams at the UE and one or more transmit beams at the UE. The UE may identify a selected DL beam of the one or more DL beam(s) for communications from the base station to the UE. The UE may transmit a random access channel (RACH) message to the base station using a resource and/or a RACH waveform selected based on the selected DL beam based at least in part on the selected DL beam and the nature of correspondence.

    Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a sounding reference signal (SRS) configuration for user equipment (UE). The base station may transmit an SRS grant message to a UE indicating the SRS configuration. An indication of SRS parameters may be included in the SRS grant message, and may include the SRS parameters or a location of the SRS parameters. That is, SRS parameters may be transmitted in a control channel with the SRS grant message or may be separately sent in a data channel as indicated by the indication of SRS parameters. In some cases, SRS parameters may be determined based on previously received UE feedback regarding channel conditions or power limitations. Alternatively, the base station may make its own environment measurements or assign SRS parameters autonomously. The UE may signal SRS transmissions to the base station according to the SRS grant message.

    Abstract: When beamforming (e.g., via a millimeter wave system (mmW)) is used for wireless communication, a base station may transmit beams that are directed to certain directions. Due to the directional nature of the beams in the mmW system, an approach to determine a beam that provides a desirable gain is studied. The apparatus may be a user equipment (UE). The apparatus receives, from a base station, a plurality of signals through a plurality of beams of the base station, each of the plurality of beams corresponding to a respective antenna port of a plurality of antenna ports of the base station. The apparatus receives from the base station a number of beams whose information should be fed back to the base station. The apparatus performs channel estimation for each beam of the plurality of beams from the plurality of antenna ports based on the plurality of signals.
