Abstract
A method for performing a handover by a subscriber station (SS) in a broadband wireless communication system including a serving base station (BS) communicating with the SS, and at least one neighbor BS neighboring the serving BS. The SS receives downlink signals from the serving BS and the neighbor BS; measures an arrival time difference between the downlink signal received from the serving BS and the downlink signal received from the neighbor BS; and transmits the measured arrival time difference to the serving BS.

Methods and apparatus for facilitating robust forward handover in long term evolution (lte) communication systems

TL;DR: In this article, a user terminal such as a UE may store identity information associated with a source cell, and use this information in accessing target or other cells subsequent to radio link failure so as to facilitate access to context information of the user terminal.

Method and system for dynamic spectrum access using specialty detectors and improved networking

TL;DR: In this article, a DSA-enabled device senses spectrum use in a region and, based on the detected spectrum use, selects one or more communication channels for use, while avoiding or reducing interference with other devices.
Patent

Pilot signal transmission for an orthogonal frequency division wireless communication system

TL;DR: In this article, transmission patterns for pilot symbols transmitted from a mobile station or base station are provided. The transmission pattern allows for improved receipt of the pilot symbol transmitted, and schemes for improving the ability to multiplex pilot symbols without interference and/or biasing from different mobile stations over the same frequencies and in the same time slots.

Mobile station assisted timing synchronization in a cdma communication system

TL;DR: In this article, the slave base station attains synchronization with the reference base station (62) through messages (504) transmitted from and received by a mobile station (60) either in the soft handoff region between the reference BS and the slave BS (64) or within a range which allows the mobile BS to communicate with the slave SA.

Method and apparatus for measuring timing of signals received from multiple base stations in a cdma communication system

TL;DR: In this paper, the arrival times of transmissions received at a remote terminal from a number of base stations were measured in the time period between updates of a reference oscillator used for the measurements.
Patent

Method and system for handoff between an asynchronous CDMA base station and a synchronous CDMA base station

TL;DR: In this paper, a method and system that enables faster acquisition of the forward link signal of a target base station in a mixed network of synchonous and asynchronous base stations is disclosed.
Patent

Method and apparatus for providing a time adjustment to a wireless communication system

TL;DR: In this article, a method for providing time adjustment to the second base transceiver station (201) in a wireless communication system including at least a first (101) and a second (200) transceiver stations is presented.

Central multiple access control for frequency hopping radio networks

TL;DR: Parked wireless slave units are also assigned a unique response number by the master as mentioned in this paper, where the parked slave unit desires access to the channel, it transmits a response in an N:th slave-to-master time slot following the polling beacon packet, where N is a function of the slave's unique response numbers.
