Abstract: Methods, systems, and devices for communication timing (e.g., random access channel (RACH) timing) in a wireless communication are described. A base station and a user equipment (UE) may perform a communication procedure (e.g., to establish a communication link between the base station the UE). The communication timing associated with the communication procedure may depend on the numerology used for the communication procedure and may be conveyed by the base station to the UE in a control message or via system information. In some cases, the numerology may indicate the communication timing.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit downlink control information (DCI) messages to a user equipment (UE). A DCI message may be transmitted using a particular DCI format based on the type of control information included in the DCI message. In some cases, different types of control information may be transmitted using the same DCI format. In such cases, one or more bit fields in a DCI format may be useful to a UE for one type of control information but may not be useful to a UE for another type of control information. As described herein, in order to limit the overhead associated with control information transmissions, a base station may support techniques for utilizing these bit fields in a DCI format to transmit information corresponding to the type of control information being transmitted.

Abstract: Methods, systems, and devices for wireless communication are described. A network device, such as a base station, may transmit a request message to a user equipment (UE). The request message may include a request for the UE to transmit a set of sounding reference signals (SRSs). The set of SRSs may include two (or more) beamformed signals. The network device may receive the set of SRSs according to the request message. The network device may identify, based on a co-phasing parameter associated with the two (or more) beamformed signals, an antenna port precoder configuration to use for communicating with the UE.

Abstract: Aspects of the disclosure relate to devices for coordinating resource usage. A scheduled device receives a downlink control information (DCI) grant from a scheduling device, the DCI grant identifying scheduled resources for communicating data. The scheduled device decides whether the DCI grant is acceptable for communicating the data and sends an acknowledgement to the scheduling device based on the decision and information associated with the DCI grant. The scheduled device communicates the data via the scheduled resources when the DCI grant is decided to be acceptable. A scheduling device transmits the DCI grant to the scheduled device and receives the acknowledgement from the scheduled device based on the information associated with the DCI grant. The acknowledgement indicates whether the DCI grant is acceptable for communicating the data. The scheduling device communicates the data via scheduled resources identified in the DCI grant when the DCI grant is indicated to be acceptable.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a downlink (DL) signal from a base station on one or more DL beam(s). The UE may identify a selected DL beam of the one or more DL beam(s) for communications from the base station to the UE. The UE may transmit a scheduling request message to the base station using at least one of a resource or a waveform selected based at least in part on the selected DL beam.

Abstract: The described techniques provide for the identification and utilization of different power consumption categories by a user equipment (UE) in wireless communications system. A power consumption category may correspond to a power consumption level (e.g., a powered circuitry configuration) of the UE. For example, a power consumption category may configure an analog-to-digital conversion (ADC) resolution, a digital-to-analog conversion (DAC) resolution, a number of antennas, etc., that a UE may employ for communications. In some examples, a UE may report capability information to a base station, and the base station may use the information to explicitly or implicitly (e.g., via conveying thresholds or conditions to the UE for power consumption category switching or power consumption category selection) configure the UE with various power consumption categories. As such, the power consumption categories may be used by the base station and UE, in some scenarios, for reducing power consumption.

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.

Abstract: Methods, systems, and devices for wireless communications are described that provide a mechanism for a wireless node to identify resources that are controlled by a different wireless node in the wireless backhaul communications network and in some cases autonomously transmit certain transmissions using resources of the different wireless node. A first wireless node may receive signaling that indicates whether such transmissions may be autonomously transmitted via configuration information or a flag provided in signaling to the first wireless node. The first wireless node may in some cases determine that autonomous transmissions are enabled based on a type of communication or node that provides the information for the transmissions from the first wireless node. In some cases, a priority associated with the transmissions may be used to determine whether autonomous transmissions are enabled.

Abstract: Wireless communication techniques that include beam training performed to aid mobile devices in identifying beams for use in communications (e.g., uplink communications) are discussed. A mobile device may transmit to a base station an indication of a level of beamforming reciprocity of the mobile device. A base station/gNB may transmit an indication of one or more transmission beams to be used by the mobile device for uplink wireless communication based on the level of beamforming reciprocity. The one or more transmission beams to be used by the mobile device for uplink communication may include a reciprocal transmission beam. A mobile device not capable of full beamforming reciprocity may determine a transmission beam through uplink beam training. A mobile device may transmit to a base station information using at least one of the one or more transmission beams. Other aspects and features are also claimed and discussed.
