Abstract: Aspects of the disclosure relate to improvements in random access procedures within a wireless communication network. To increase the likelihood that a user equipment (UE) will properly decode a random access response message from a base station, the base station may retransmit the random access response message one or more times. The number of retransmissions may be fixed or may be variable depending on whether the base station is able to receive or successfully decode a subsequently transmitted uplink message.

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: 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: 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: A method, an apparatus, and a computer program product for beamforming in a wireless communication are provided. The apparatus determines a beamforming direction and a SNR of at least two user equipments (UEs) and determines whether to schedule communication with the at least two UEs during a same time interval via a single communication beam based on the beamforming directions and the SNRs of the at least two UEs. When the communication with the at least two UEs during the same time interval via the single communication beam is scheduled, the apparatus allocates bandwidth resources respectively among the at least two UEs, sizes a width of the single communication beam to encompass the beamforming directions of the at least two UEs, and communicates with one or more of the at least two UEs during the same time interval via a respectively allocated bandwidth resource using the sized single communication beam.

Abstract: Techniques are described for backhaul operations in a millimeter wave wireless communication system. A first base station of the millimeter wave wireless communication system identifies an access demand and one or more access communication parameters associated with the first base station. The first base station sends information to a second base station indicative of the access demand and the one or more access communication parameters, and determines one or more backhaul communication parameters associated with the second base station of the millimeter wave wireless communication system. The first base station establishes a wireless backhaul link with the second base station via the millimeter wave wireless communication system. The first base station partitions resources between an access link with one or more user equipments and the established wireless backhaul link based at least in part on the access demand, the one or more access communication parameters, or the backhaul communication parameters.
