Abstract: A base station transmits energy related information to a mobile station, wherein the energy related information is related to at least one of an energy harvester module and an energy storage module coupled to the base station. The energy related information includes: an energy level and a maximum storage capacity of the energy storage module; an energy harvest rate and energy consumption rate. The base station and the mobile station perform energy trade off, where when the serving base station has an energy level below a threshold, the mobile station uses certain configuration to send information to the serving base station where the configuration can use more resources, such as RF chains, thereby increasing energy consumption of the mobile station while enabling the base station to conserve energy.

Abstract: Adaptation of measurement procedures for cell detection and association provide more accurate and frequent reports for use by the network, to enhance cell association. A user equipment receives, within a configured measurement bandwidth, orthogonal frequency division multiplexing symbols comprising discovery reference signals (DRS). For subframes in which the DRS are transmitted, a discovery reference signal received quality (D-RSRQ) is determined from the DRS within the received symbols as a ratio of discovery reference signal received power (D-RSRP) to carrier discovery received signal strength indicator (D-RSSI), where the D-RSRP is measured in symbols containing DRS resource elements and the D-RSSI is measured in all symbols in subframes containing the DRS. For a UE configured to also measure common reference signals, non-DRS measurements are suspended upon deactivation of a secondary cell, and measurement timing of the DRS during a deactivation period is based on a measurement timing parameter.

Abstract: Beam-steered millimeter wave signals transmitted in each of n sector slices include a sequence of primary synchronization (PSCH) symbols within predetermined symbol positions in at least one slot of a subframe. The symbols in consecutive symbol positions are each transmitted on a different one of the n slices, with the first symbol repeated on the same slice at the end. The sequence order rotates cyclically in each subframe so that two PSCH symbols are transmitted on one slice in a single subframe every nth subframe. Secondary synchronization (SSCH) and Broadcast Channel (BCH) symbols are transmitted in a predetermined pattern following the sequence of PSCH symbols. By transmitting consecutive PSCH symbols on different slices and repeating the first symbol, the mobile station can detect the best slice and beam by switching receive beams every subframe instead of every slot, relaxing time constraints on AGC adjustment while avoiding the start-at-the-edge problem.
