Embodiment Construction

[0022] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

[0023] Reference will be made in detail to various embodiment...

Abstract

A method of implicit signaling to support In-Device coexistence interference avoidance is provided. A UE sends an IDC interference indication to an eNB. The indication indicates that a serving frequency becomes unusable due to a coexistence interference problem. The indication does not explicitly indicate a frequency index or a frequency location of the unusable serving frequency. The eNB determines the serving frequency as unusable in an implicit manner. The eNB also determines an implied unusable frequency region based on the received IDC indication. The implied unusable frequency region is between the serving frequency and the ISM band. In one advantageous aspect, the eNB configures a condition for the UE, such that the UE is refrained from sending IDC interference indications unless the condition is satisfied.

Description

[0001] cross reference [0002] This application claims the following priority according to 35 U.S.C. §119: U.S. Provisional Application No. 61 / 470,711, filing date 2011 / 4 / 1, titled "Signaling Design to Support In-Device Coexistence Interference Avoidance". The subject matter of the above application is hereby incorporated by reference. technical field [0003] The present invention relates to wireless network communications, and in particular to in-device coexistence interference avoidance. Background technique [0004] Today, ubiquitous network access has been basically realized. From a network infrastructure perspective, different networks belong to different layers (for example, distribution layer, cellular layer, hotspot layer, personal network layer, and fixed / line layer) that provide different degrees of coverage and connectivity to users . Because the coverage of a particular network is not available in all locations, and because different networks may be optimiz...
