Embodiment Construction

[0030] The description set forth below in conjunction with the accompanying drawings is a description of various structures of the present invention, and does not mean that the present invention can be realized only in these structures. The description includes specific details to provide a thorough understanding of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the present invention.

[0031] see first figure 1, a wireless communication system 10 provides a system and method for reducing downlink interference 12 from a non-serving (interfering) base station 14 for a wireless device 16 in which data packet communications are served from the serving base station 20 to the wireless device 16 over a wireless network 18 . In one aspect, the non-servi...

Abstract

A method to mitigate interference in a wireless system is provided. The method includes processing a set of radio network identifiers and limiting a number of hypotheses associated with the radio network identifiers in order to mitigate interference in a wireless network. In another aspect, the method includes processing a set of hypotheses and limiting the set of hypotheses by limiting a number of downlink grants to a common space, limiting the number of downlink grants to a number of instances, or limiting the number of grants to a physical downlink control channel (PDCCH) type. In yet another aspect, the method includes processing a downlink set and generating a target termination level for the downlink data set, the termination level associated with a Hybrid automatic repeat-request.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 147,411, filed January 26, 2009, and Provisional Application No. 61 / 147,615, both titled "Inter-cell Interference Cancellation Framework," filed January 27, 2009 rights, these two provisional applications have been assigned to the assignee of the present application and are hereby expressly incorporated by reference in their entirety into this application. technical field [0003] In general, the following description relates to wireless communication systems, and in particular, the following description relates to methods for mitigating downlink interference. Background technique [0004] Wireless communication systems are widely deployed today to provide various types of communication content, eg, voice, data, and so on. These systems may be multiple-access systems that can support communication with multiple users by sharing available system...
