Embodiment

[0082] CLAIMS 1. A method for performing cell reselection in a wireless transmit receive unit (WTRU), the method comprising:

[0083] determining whether to reselect the target cell based at least on internal measurements;

[0084] automatically perform cell reselection; and

[0085] A variable Enhanced Radio Network Temporary Identifier (E-RNTI) is cleared when cell reselection has been determined.

[0086] 2. According to the method described in embodiment 1, the method also includes:

[0087] receiving broadcast system information from the target cell; and

[0088] Determine the enhanced dedicated channel (E-DCH) capability of the target cell in CELL_FACH according to the system information.

[0089] 3. The method of embodiment 2, further comprising transmitting an update message containing an indication of the WTRU's E-DCH capabilities in CELL_FACH.

[0090] 4. The method of embodiment 3, wherein the indication of the capabilities of the E-DCH in the CELL_FACH is an in...

Abstract

The invention discloses a wireless transmit receive unit (WTRU) and a method for cell reselection associated with a WTRU. The method comprises the following steps: determining that cell reselction of a WTRU is controlled by network; carrying out channel measurement; and sending a measurement report to the network.

Description

[0001] This application is a divisional application of the Chinese invention patent application with the application number 200880123583.X, the application date is December 30, 2008, and the invention title is "Method and Device for Cell Reselection". technical field [0002] This application relates to wireless communications. Background technique [0003] Wireless communication systems are well known in the art. Communications standards are developed to provide global connectivity for wireless systems and achieve performance goals such as throughput, latency, and coverage. The currently widely used standard is called Universal Mobile Telecommunications System (UMTS), which was developed as part of the third generation (3G) radio system and remains in the 3rd Generation Partnership Project (3GPP). [0004] figure 1 The architecture of an exemplary UMTS system according to current 3GPP specifications is described in . The UMTS network architecture includes a Core Network ...
