Abstract: Methods, systems, and apparatuses are described for wireless communication at a base station. The base station may transmit a control message to a set of user equipments (UEs) using a directional transmission having a first beamform width. The base station may exchange, according to the control message, data messages with a first UE of the set of UEs using a directional transmission having a second beamform width. The second beamform width may be different from the first beamform width. The base station may exchange, according to the control message, data messages with a second UE of the set of UEs using a directional transmission having a third beamform width. The third beamform width may be different from the first beamform width, the second beamform width, or both.

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: 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: A structure where there are self-contained subframes/slots with smaller TTIs within the subframes/slots is provided to address the issues in MMW scheduling. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may transmit downlink information to at least one UE using a plurality of downlink TTIs within a subframe/slot. The apparatus may receive uplink information from the at least one UE using at least one uplink region within the subframe/slot. In another aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive downlink information from a base station using at least one downlink TTI within a subframe/slot. The subframe/slot may include a plurality of downlink TTIs and at least one uplink region. The apparatus may transmit uplink information to the base station using the at least one uplink region within the subframe/slot.

Abstract: Methods, systems, and devices for wireless communication are described. Some examples provide for identifying a primary synchronization signal (PSS) sequence of a synchronization subframe, determining, for the synchronization subframe, an extended synchronization signal (ESS) sequence based at least in part on the PSS sequence and transmitting the synchronization subframe. Other examples provide for generating an ESS sequence for a synchronization subframe to be communicated to a UE, scrambling the ESS sequence based at least in part on cell-specific information associated with the base station and transmitting, to the UE, the scrambled ESS sequence in the synchronization subframe.

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: A wireless device configured for discontinuous reception (DRX) may and operating in a system that uses directional beamforming may identify a random access time period after awaking from a DRX sleep mode. The device may then transmit a scheduling request during the random access time period. In some cases, the device may transmit the scheduling request using frequency resources also associated with random access transmissions. In other cases, the device may utilize resources that are not associated with random access. The determination of which frequency resources are used may depend on the length of the DRX. That is, if a device has been in a sleep mode for a long time, it may use random access frequency resources that are associated with a more robust transmission configuration.
