Abstract: Methods, systems, and devices for wireless communication are described. A network server may configure a base station for beamforming communications based on a service type of data used by a user equipment (UE). The network server may determine the service type of the data based on position data of the UE, along with other statistical information related to data usage. The position information may include global position system (GPS) information, gyroscope information, accelerometer information, or information related to the UE's subarray geometry. The base station may receive the position information from the UE and convey it to the network server. The network server may use the position information to generate a network map and to identify the service type of communication.

Abstract: Certain aspects of the present disclosure provide techniques for assisted power control for an uplink signal transmitted during a RACH procedure. A UE may determine a transmit power for transmitting a message during a RACH procedure with a secondary BS, based at least in part, on communication between the UE and a primary BS. The UE may transmit the message to the second BS during the RACH procedure based, at least in part, on the determined transmit power.

Abstract: In millimeter wave systems, user equipment may not be able to receive RACH parameters through a PDCCH when the information is transmitted with an omni-directional beam. In an aspect of the disclosure, an apparatus, such as a base station, may determine the RACH parameters and transmit a subset of the RACH parameters via a PBCH. The user equipment may receive the RACH parameter subset and initiate a RACH procedure.

Abstract: Aspects of the present disclosure provide methods for modifying the numerology of the D2D frame structure to match the numerology of the Macro cell communication frame structure. Particularly, the present disclosure introduces techniques that allow the D2D devices to partition a long-TTI D2D transmission into a plurality of segments such that each segment may fit into a short-TTI MiCr uplink (UL) subframe. The present disclosure also provides techniques for scheduling D2D transmission and managing transmission power of the D2D communication to minimize the interference with the MiCr communication on the macro cell while maximizing the spectrum utilization.

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: According to an aspect of the disclosure, a base station may convey the parameter information to the UE based on selection of particular resources to be used for transmission of synchronization signals, where the selected resources correspond to the particular parameter information. The UE may blindly detect the synchronization signals on various candidate resources and determine the parameter information based on the resources where the synchronization signals are detected. The apparatus may be a base station. In an aspect, the base station determines parameter information of one or more parameters. The base station selects, based on the parameter information, synchronization resources from a plurality of candidate resources for transmission of one or more synchronization signals, where the selected synchronization resources correspond to the parameter information. The base station transmits the one or more synchronization signals using the selected synchronization resources.

Abstract: Traffic in a first cell may experience interference from or may cause interference to traffic in an adjacent cell, which may lead to undesirable performance in one or both of the first cell and the adjacent cell. For example, a user equipment (UE) near an edge of the first cell may experience appreciable interference based on the reuse of resources. Accordingly, for transmissions in adjacent cells over a same band or sub-band, one UE may need to reduce transmit power in order to yield to another UE in an adjacent cells. An apparatus may be configured to determine first traffic associated with a first priority and second traffic associated with a second priority. The apparatus may be further configured to assign, based on the first priority and second priority, a first set of resources to the first traffic and a second set of resources to the second traffic.
