Abstract: Certain aspects of the present disclosure relate to methods and apparatus for phase noise estimation in data symbols for millimeter wave (mmW). A method for wireless communications by a transmitting device is provided. The method generally includes identifying a phase noise metric associated with at least one receiving device; determining a phase noise pilot configuration based, at least in part, on the identified phase noise metric; and providing an indication of the phase noise pilot configuration to the at least one receiving device. A receiving device can receive the phase noise pilots in accordance with the configuration and determine phase noise for a data symbol based on the received phase noise pilots.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a number of beam directions that satisfy a transmission power condition. The UE may select a beam direction for a random access signal by choosing one of the beam directions that satisfies additional criteria, such as transmitting a random access message at the next opportunity. The transmission power may be selected based on a target receive power and a path loss for the selected beam. In some cases, if the sum of the path loss for a beam direction and the target receive power exceeds a maximum transmission power by more than a predetermined amount, the random access signal will not be transmitted using that beam. In some cases, if a response to the random access is not received, a different beam direction may be selected, the transmission power may be increased, or both.

Abstract: Various aspects of the disclosure relate to communicating random access information and uplink control information. In some aspects, a user equipment (UE) or other suitable apparatus transmits physical uplink control channel (PUCCH) information concurrently with random access channel (RACH) information transmitted by another UE or other apparatus. For example, the RACH access information and the PUCCH information may be frequency division multiplexed orthogonal tones. The disclosure relates in some aspects to using downlink-uplink (DL-UL) channel reciprocity to determine symbol and/or tone locations. For example, a base station or other suitable apparatus may initially sweep across different directions in different time slots to transmit signals during a synchronization sub-frame. A UE or other suitable apparatus can then find an appropriate RACH symbol from its best synchronization beam index and transmit PUCCH information in those symbols.

Abstract: In a process of beam change, the base station transmits a beam change instruction to a user equipment to confirm a change from a current beam to another beam. The base station determines to change from a first beam to a second beam. The base station generates a beam change instruction to indicate the determination to change from the first beam to the second beam. The base station transmits, to a UE, the beam change instruction in a downlink control information (DCI). The base station determines whether or not the beam change instruction is detected by the UE.

Abstract: In one aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided to reduce overhead at the expense of increasing latency for UEs with weak link gain, while latency for most UEs may remain the same. The apparatus may be a UE. The apparatus may transmit a RACH preamble to a base station in one or more attempts. The apparatus may receive, through a random access response message from the base station, information including the number of attempts the base station uses to decode the RACH preamble. The apparatus may adjust the transmission power for the connection request message according to the number of attempts the base station uses to decode the RACH preamble. The apparatus may transmit the connection request message using the adjusted transmission power.

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: Methods, systems, and devices for wireless communications are described that provide for multiple timing advance offsets that may be used in communications between wireless devices on a wireless communications system. A first timing advance offset may be a fixed offset that has a predetermined value or is selected from a set of available predetermined values, and a second timing advance offset may be adjustable by a wireless device. The second timing advance offset may be used in cases where relatively large distances between wireless devices are present in a system, where certain fixed timing advances are used in addition to or irrespective of a receiving devices propagation delay, where one or more parent nodes have an associated timing reference, or combinations thereof.

In some aspects, a node of a network may determine an extended slot format indicator for the node based at least in part on a received extended slot format indicator of a parent node of the node and a received null adjust request from a child node of the node, wherein the extended slot format indicator for the node includes a null field identifying a non-schedulable resource of the node; may provide the determined extended slot format indicator to the child node; and may provide the received null adjust request to the parent node. Numerous other aspects are provided.
