Abstract

Techniques are described for millimeter wave wireless communication. One method includes configuring a synchronization slot associated with a plurality of synchronization blocks, configuring a transmission of each synchronization block of the plurality of synchronization blocks based on the configured synchronization slot, assigning a synchronization region to a first frequency portion associated with a transmission beam of each synchronization block, assigning at least one of a data region or a control region to a second frequency portion associated with the transmission beam of each synchronization block, and transmitting a synchronization signal during the synchronization region and transmitting at least one of data signal during the data region or control information during the control region to a wireless node.

Claims (40)

1. An apparatus for wireless communication, in a system comprising:

one or more processors;

one or more memories in electronic communication with the one or more processors; and

instructions stored in the one or more memories and operable, when executed by the one or more processors, to cause the apparatus to:

monitor a synchronization channel associated with a beamformed synchronization block of a synchronization slot; and

receive a synchronization signal associated with a first frequency portion associated with a downlink reception beam of the synchronization block and at least one of data or control information associated with a second frequency portion associated with the downlink reception beam of the synchronization block during the synchronization slot.

2. The apparatus of claim 1 , wherein the instructions, when executed by the one or more processors, are further configured to cause the apparatus to:

configure to detect at least one of the data or the control information associated with the synchronization block;

determine an absence of at least one of the data or control information during the synchronization block; and

transition into a micro-sleep state based at least in part on the absence.

3. The apparatus of claim 1 , wherein the instructions, when executed by the one or more processors, are further configured to cause the apparatus to:

transmit a random access channel (RACH) signal during a subframe of an uplink transmission beam.

4. The apparatus of claim 3 , wherein the synchronization block is divided into multiple orthogonal frequency division multiplexing (OFDM) symbols based at least in part on time-division multiplexing (TDM).

5. The apparatus of claim 4 , wherein the instructions, when executed by the one or more processors, are further configured to cause the apparatus to:
