摘要： Systems and methods of the present disclosure are directed to a method performed by a coordinating Wireless Communication Device (WCD) for cooperation between WCDs for increased transmission efficiency. The method includes obtaining signal strength measurements for a plurality of network cells comprising a serving cell and neighboring cell(s), on behalf of a group of WCDs comprising the coordinating WCD and additional WCD(s) that have the same mobility pattern. Each WCD in the group of WCDs is in an INACTIVE or IDLE mode. The method includes, based on the signal strength measurements, performing a cell reselection procedure for the group of WCDs to a neighboring cell of the network cells. The method includes providing, to each WCD in the group of WCDs via a respective sidelink, data indicative of performance of the cell reselection procedure to the neighboring cell of the network cells.

摘要： A radio base station includes multiple antennas associated with a cell. Multiple mobile radios are selected to receive transmissions over a shared radio channel during a predetermined time interval. Information is transmitted over the shared radio channel to multiple mobile radios in the cell during the predetermined time interval using multiple antenna beams. As a result, interference from the transmission appears as white additive Gaussian noise in time and in space in the cell. A "flashlight effect" caused by a single beam transmission over the shared channel during a predetermined time interval that would normally detrimentally impact mobile channel quality detection is avoided. Other methods for avoiding the flashlight effect are described.
