Abstract
Description
本特許出願は、2005年10月27日に出願され、本願の譲受人に譲渡された「WIRELESS COMMUNICATION」と題する米国仮特許出願第60/731128号明細書の優先権を主張し、これを明示的に参照により本明細書に援用する。
・分野
本開示は、包括的には無線通信に関し、特に、タイミング補正メッセージを送受信する方法及び装置に関する。
無線通信システムは広く普及した手段になっており、無線通信システムによって世界中の大多数の人々が通信するようになっている。無線通信装置は、消費者のニーズを満たし、可搬性及び利便性を向上させるために、より小型且つより強力になっている。携帯電話のような移動装置の処理能力の増大は、無線ネットワーク伝送システムに対する需要の増大に繋がっている。通常、このようなシステムは、そのシステムを介して通信するセルラ装置ほど容易には更新されない。移動装置の能力が拡大するにつれて、無線装置の新規の能力及び改良された能力の十分な利用を促進するように旧式の無線ネットワークシステムを維持することが難しくなる可能性がある。
以下に、1つ又は複数の実施形態の簡略化した概要を提示して、このような実施形態の基本的な理解を提供する。この概要は、意図されるすべての実施形態の広範囲に渡る全体像ではない。また、この概要は、すべての実施形態のキーとなる要素又は重要な要素を特定することを意図するものでもなければ、いずれかの又はすべての実施形態の範囲の限定を意図するものでもない。その唯一の目的は、1つ又は複数の実施形態のいくつかの概念を簡略化した形で、後述するより詳細な説明への前置きとして提示することである。
これより、図面を参照してさまざまな実施形態を説明する。図面において、同様の参照符号は全体を通じて同様の要素を指すために使用される。以下の記載では、1つ又は複数の実施形態の完全な理解を提供するために、説明を目的として、多くの特定の詳細が述べられる。しかしながら、このような特定の詳細なしでこのような実施形態(複数可)を実施することができることは明らかである。他の場合では、周知である構造及び装置は、1つ又は複数の実施形態の説明を容易にするためにブロック図の形で示される。
