Abstract: The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Abstract: The apparatus may be a base station. The apparatus processes a plurality of synchronization signals by performing time-division multiplexing (TDM) of at least one of a plurality of first synchronization signals of different types and at least one of the plurality of second synchronization signals of different types, the plurality of synchronization signals including the plurality of first synchronization signals and the plurality of second synchronization signals. The apparatus transmits the processed synchronization signals to a user equipment (UE).

Abstract: A UE may select a first beam for communication with a base station. The UE may attempt, through the selected first beam, at least one RACH procedure with the base station. The UE may determine that the at least one RACH procedure failed with the base station. The UE may send, after a successful RACH procedure with the base station, information indicating that the at least one RACH procedure failed. In an aspect, the UE may select a new beam for communication with the base station after the determination that the at least one RACH procedure failed, and at least a portion of the successful RACH procedure may be performed through the selected new beam.

Abstract: A UE may receive, from a base station, a message requesting BSI. The UE may determine a number N of BSI reports to send to the base station, and each BSI report may indicate a beam index corresponding to a beam and a received power associated with the beam. The UE may send, to the base station, N BSI reports based on the message requesting BSI. The UE may receive, from the base station, a set of signals through a set of beams, and determine the received power for each signal of the set of signals received through each beam of the set of beams, each received power may be associated with a beam of the set of beams.

Abstract: A first apparatus may transmit, to a user equipment (UE), on a control channel, one or more indications of one or more beam indexes corresponding to one or more beams. The first apparatus may transmit, to the UE, one or more reference signals through the one or more beams corresponding to the one or more beam indexes. The reference signals may be used by the UE to select a best subarray and/or receive combiner for communication with the first apparatus.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a subframe that includes physical broadcast channel (PBCH) signals interspersed within beam reference signals, where the subframe may be a synchronization subframe including one or more synchronization signals. In some cases, the beam reference signals from different antenna ports may be code division multiplexed or frequency division multiplexed over multiple frequency tones. A user equipment (UE) may use the beam reference signals to generate channel estimates for the PBCH signals. In some cases, orthogonal cover codes for code division multiplexed signals may be selected to facilitate generation of channel estimates for PBCH signals transmitted using nearby frequency tones.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to send, in a first network, a scheduling request (SR) associated with a second network. The apparatus may be further configured to receive an uplink grant based on the SR. The apparatus may be further configured to send, in the second network, uplink transmission based on the uplink grant. In an another aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to receive, in a first network, a scheduling request (SR) associated with a user equipment (UE). The apparatus may be further configured to generate an uplink grant based on the SR. The apparatus may be further configured to send, in a second network, the uplink grant to the UE.

Abstract: The present disclosure relates to wireless communication in mmW networks. The apparatus may be a base station. The apparatus may be configured to determine a first symbol index and a second symbol index associated with downlink resources allocated to a UE. The first symbol index may indicate when the downlink resources begin in a subframe, and the second symbol index may indicate when the downlink resources end in the subframe. The apparatus may be configured to transmit an indication of the first symbol index and the second symbol index to the UE.

Abstract: Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.
