Embodiment Construction

[0051] In this document, the words "embodiment", "modification" and similar expressions are used to refer to a specific device, process or article, not necessarily to the same device, process or article. Therefore, "one embodiment" (or a similar expression) used in one place or context may refer to a specific device, process, or article, while the same or similar expression in a different place may refer to a different device, process or article. products. The expression "alternative embodiment" and similar phrases are used to indicate one of several different possible embodiments. The number of possible embodiments is not necessarily limited to two or any other number.

[0052] The word "exemplary" is used herein in the sense of "serving as an instance, instance, or illustration." Embodiments described herein as "exemplary" are not necessarily to be construed as preferred or advantageous over other embodiments. All embodiments described in this specification are exemplary ...

Abstract

Multi-carrier point-to-multi-point CDMA system implementation reduces hardware changes in legacy single-carrier systems. The number of common downlink channels, such as timing / synchronization and paging channels, is reduced by designating an anchor carrier for transmitting these channels. Procedures for adding carriers and carrier acquisition are simplified through common carrier timing, signaling by the network to the user equipment (UE) of timing offsets and scrambling code selection, and other measures. Channel reuse is employed to minimize changes in asymmetric systems with different numbers of uplink and downlink carriers. Channel Quality Indicator (CQI) field is divided into multiple subfields to enable transmission of multiple CQIs and ACK / NACK indicators on one uplink carrier.; Joint and separate scheduling schemes are shown for concurrent scheduling of a data stream transmission to a UE via multiple downlink carriers.

Description

[0001] Claim of priority under 35 U.S.C § 119 [0002] This patent application claims priority to Provisional Application No. 60 / 676,109, filed April 28, 2005, entitled "Method and Apparatus for Multi-Carrier Wireless Communications," which also claims Priority to Provisional Application No. 60 / 676,110, entitled "Method and Apparatus for Signaling in Wireless Communications," filed on . Said provisional application is assigned to the assignee of the present application and is expressly incorporated herein by reference as if fully described herein (including all figures, tables and claims). technical field [0003] The present invention relates generally to telecommunications, and more particularly to multi-carrier and multi-cell communications in wireless systems. Background technique [0004] Modern communication systems are expected to provide reliable data transmission for a wide variety of applications such as voice and data applications. In the context of point-t...
