Embodiment Construction

[0026] When referred to hereinafter, the term "wireless transmit / receive unit (WTRU)" includes, but is not limited to, user equipment (UE), mobile station, fixed or mobile subscriber unit, pager, cellular telephone, personal digital assistant (PDA), computer , machine-to-machine (M2M) devices, sensors, or any other type of user equipment capable of operating in a wireless environment. When referred to hereinafter, the term "base station" includes, but is not limited to, a Node B, site controller, access point (AP), or any other type of interface device capable of operating in a wireless environment.

[0027] The network may assign at least one downlink and / or at least one uplink carrier as an anchor downlink carrier and an anchor uplink carrier, respectively. In multi-carrier operation, a WTRU may be configured to operate on two or more carriers, also called frequencies. Each of these carriers may have different characteristics and logical associations with the network and WT...

Abstract

A method and apparatus are disclosed for multi cell wireless communication wherein a status of a secondary serving cell is determined. On the condition that the secondary serving cell is disabled, a Hybrid Repeat Request (HARQ) process associated with the secondary serving cell is released.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 113,149, filed November 10, 2008, which is hereby incorporated by reference as if set forth in its entirety. technical field [0003] This application relates to wireless communications. Background technique [0004] Wireless communication systems are evolving to meet the need to provide continuous and fast access to data networks. To meet these demands, wireless communication systems may use multiple carriers for data transmission. A wireless communication system using multiple carriers for data transmission may be referred to as a multi-carrier system. The use of multicarriers extends to cellular as well as non-cellular wireless systems. [0005] Depending on how many of the carriers are available, a multi-carrier system can increase the available bandwidth in a wireless communication system. For example, a two-carrier system will double the...
