TL;DR: In this article, the authors proposed a multi-beam antenna system with a single narrow beam antenna directed at the base station, where the transceivers are equipped with antennas providing beam divergence small enough to ensure efficient spatial and directional partitioning of the data channels so that an almost unlimited number of point-to-point transceiver nodes can simultaneously use the same millimeter wave spectrum.
Abstract: A wireless cellular communication system in which cellular base stations utilize multi-beam antenna to communicate with a large number of users. Each of the base station beams is a narrow beam of less than 10 degrees permitting reuse of available spectrum many times. A preferred antenna is described which broadcasts about 12 simultaneous beams, each about 5 degree, the 12 beams together covering a fan arc of about 60 degrees with the beams overlapping somewhat but interference is avoided by having adjacent beams broadcast at different frequencies within an authorized broadcast bandwidth. Six antennae mounted in a hexagonal manner thus cover a 360-degree azimuthal range. Preferably, users of the system communicate with the base station using a single narrow beam antenna directed at the base station. Since all beam are narrow beams many base stations may be located in the same cellular region permitting more than an order of magnitude increase in the utilization of available bandwidth and permitting a huge increase in bandwidth per customer. In a preferred embodiment the base stations communicate with a central office via a narrow-beam millimeter wave trunk line. The transceivers are equipped with antennas providing beam divergence small enough to ensure efficient spatial and directional partitioning of the data channels so that an almost unlimited number of point-to-point transceivers will be able to simultaneously use the same millimeter wave spectrum.

TL;DR: In this paper, a test set (30, 36) for wireless communication networks, particularly cellular networks, has been proposed, which can be fixed or mobile, providing essentially continuous monitoring of voice channels within a given cell, and can send an alarm in near realtime to the network control center when a faulty voice channel is detected.
Abstract: A testing system (28) for wireless communication networks, particularly cellular networks, having a test set (30, 36) located in a cell site which communicates through the cell's base station to a responder (32, 38) at the mobile telephone switching office (MTSO, 34). The test set (30, 36), which includes a measurement module (48), controller (44), modem (46), and cellular phone (50), initiates the call to the responder (32, 38), and directs the responder to transmit and receive certain test signals which are then measured by the measurement module. The test set (30, 36), which may be fixed or mobile, provides essentially continuous monitoring of voice channels within a given cell, and can send an alarm in near real-time to the network control center when a faulty voice channel is detected.

TL;DR: In this paper, a method for locating a mobile station, comprising the steps of using fixed transmitting stations (BS1, BS2, BS3) for locating the target mobile station (MS1) by transmitting a measurement signal from each fixed transmitting station to the mobile station and using a relay station (MSN1 - MSN5) which is adapted to receive said measurement signal, and to forward said signal to said target mobile stations.
Abstract: The present invention discloses a method for locating a mobile station, comprising the steps of using fixed transmitting stations (BS1, BS2, BS3) for locating a target mobile station (MS1) by transmitting a measurement signal from each fixed transmitting station to said mobile station, using a relay station (MSN1 - MSN5) which is adapted to receive said measurement signal from the corresponding fixed transmitting station and to forward said signal to said target mobile station (MS1), in case a direct transmission from one or more of said fixed transmitting stations (BS1, BS2, BS3) is not available, and determining the distance between said target mobile station (MS1) to the fixed transmitting stations and/or the relay stations on the basis of said measurement signal, and locating the position of said target mobile station on the basis of the determined distances. By this method, it is possible to locate a mobile station even if there is no direct connection via air to neighbouring base stations.

TL;DR: In this paper, a MAC protocol data unit (PDU) in a header, mini-header, or subheader is used to provide feedback from wireless terminals to base stations.
Abstract: Aspects of the present invention provide additional MAC functionality to support the PHY features of a wireless communication system framework. The additional MAC functionality aids in enabling feedback from wireless terminals to base stations. In some aspects of the invention the feedback is provided on an allocated feedback channel. In other aspects of the invention the feedback is provided by MAC protocol data units (PDU) in a header, mini-header, or subheader. The feedback may be transmitted from the wireless terminal to the base station autonomously by the wireless terminal or in response to an indication from the base station that feedback is requested. Aspects of the invention also provide for allocating feedback resources to form a dedicated feedback channel. One or more of these enhancements is included in a given implementation. Base stations and wireless terminals are also described upon which methods described herein can be implemented.

TL;DR: In this article, the authors present a communication control method for dual-connectivity communication which uses a master base station that establishes RRC connection with a user terminal and a secondary base station providing a supplementary wireless resource to the user terminal.
Abstract: A communication control method pertaining to an embodiment of the present invention is for controlling dual connectivity communication which uses a master base station that establishes RRC connection with a user terminal and a secondary base station that provides a supplementary wireless resource to the user terminal The communication control method comprises: a step in which the master base station receives, from the user terminal, a measurement report which includes measurement results found for each cell in the user terminal; and a step in which the secondary base station receives, from the master base station, a supplementary request for requesting the allocation of resources to the user terminal In the step for receiving a supplementary request, the master base station includes, in the supplementary request, measurement results for a cell of the secondary base station which is included in the measurement results, and transmits the same
