Abstract

Systems and methods that designate a control attachment point(s) during transmission of data in a Coordinated Multipoint (CoMP) system. The control attachment point is represented by an anchor cell to address control signaling and represent a User Equipment's (UE) interaction with the wireless communication system from a perspective of control (e.g., supplying / sending grants to the UE, transmitting / receiving ACKS on the downlink / uplink to the UE, control information (CQI), and the like.) The cells can further engage in backhaul transfer of information therebetween, and dynamic switching / change of anchor point based on criteria such as control loading, channel quality, and the like can further be implemented.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 108,297, filed October 24, 2008, entitled "ANCHOR CELL FOR NETWORK MIMO," which is assigned to the assignee of this application, and is hereby assigned to It is expressly incorporated into this application by reference. technical field [0003] In general, the following description relates to wireless communications and, in particular, to control signaling in a Coordinated Multipoint (CoMP) system. Background technique [0004] In order to provide various types of communication content such as voice, data, etc., wireless communication systems are widely deployed. A typical wireless data system may be a multiple-access system capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power, . . . ). Examples of such multiple-access systems may include Code Division Multiple Access (CDM...
