Embodiment Construction

[0034] The techniques described in this application can be used in various wireless communication systems such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier FDMA (SC-FDMA) and other systems. The terms "system" and "network" are often used interchangeably. A CDMA system may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, and so on. UTRA includes Wideband-CDMA (W-CDMA) and other variants of CDMA. CDMA2000 covers the Interim Standard (IS)-2000, IS-95 and IS-856 standards. A TDMA system can implement a radio technology such as Global System for Mobile Communications (GSM). OFDMA systems can implement radio technologies such as Evolved Universal Terrestrial Radio Access (Evolved UTRA or E-UTRA), Ultra Mobile Broadband (UMB), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi...

Abstract

When a handover failure occurs and / or is anticipated to occur, an optimized cell can be selected and user equipment can transfer to the optimized cell. This optimized cell can differ from a previous cell based upon various factors such as anticipated interference and load balancing. Once there is identification of a handover failure a cell can return to a previous frequency and an appropriate cell can be determined. Instruction of the cell that should be used can be determined by user equipment as well as from a network entity.

Description

[0001] This application claims priority to US Patent Application Serial No. 60 / 992,658, filed December 5, 2007, entitled "HANDOVERFAILURE PROCEDURES IN COMMUNICATION SYSTEMS." The entire content of this application is incorporated into this application by reference. technical field [0002] The following description relates to wireless communication in general and, more specifically, to the operation of relevant user equipment after handover failure. Background technique [0003] In order to provide various communication contents such as voice, data, and the like, wireless communication systems are widely deployed. A typical wireless communication system may be a multiple-access system, which supports multiple users to communicate by sharing available system resources (eg, bandwidth, transmit power...). Examples of such multiple-access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Acce...
