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: Certain aspects of the present disclosure provide techniques for beam refinement. A base station provides information regarding what transmit beams are used to transmit different reference signal (RS) resources. In some cases, the information indicates whether a same transmit beam is used to transmit a set of RS resources (e.g., symbol, sub-symbol, or frequency resources) or whether different transmit beams are used to transmit the set of RS resources.

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: A structure where there are self-contained subframes/slots with smaller TTIs within the subframes/slots is provided to address the issues in MMW scheduling. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may transmit downlink information to at least one UE using a plurality of downlink TTIs within a subframe/slot. The apparatus may receive uplink information from the at least one UE using at least one uplink region within the subframe/slot. 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. The apparatus may transmit uplink information to the base station using the at least one uplink region within the subframe/slot.

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: Uplink transmission power levels may be adjusted in response to changes in a directional beam used for wireless communications. A beam change may be identified, wherein the beam change includes a transition from a first transmission configuration based on a first beam direction of a cell to a second transmission configuration based on a second beam direction of the cell. A downlink (DL) message associated with the beam change may be received, wherein the DL message comprises a transmission power indication. An uplink (UL) message may be transmitted at a power level based at least in part on the transmission power indication.

Abstract: Methods, systems, and devices for wireless communication are described. Methods, systems, and devices provide for different tone spacing schemes for different channels. Methods, systems, and devices also provide for different tone spacing schemes for different stages of communication between a UE and a base station. The base station may indicate, to the UE, the tone spacing scheme in a control channel, a synchronization signal, or a reference signal and the tone spacing scheme may be selected by the base station from available tone spacing schemes for communication. Tone spacing schemes may also be referred to as numerologies.
