Embodiment Construction

[0051] Referring now to the drawings, wherein like numerals represent like parts throughout.

[0052] review

[0053] Improved solutions especially for receiver diversity management are disclosed, including in one embodiment for enabling "smart" reception in mobile devices such as, for example, Long Term Evolution (LTE) enabled User Equipment (UE) Method and apparatus for diversity management. In one implementation, intelligent diversity management includes selectively disabling receive diversity (RxD) in devices when multiple criteria are met, including (i) capacity criteria, and (ii) connectivity criteria. In one variant, the connectivity condition applies to both LTE "idle" and "connected" states to ensure that the Physical Downlink Control Channel (PDCCH) is reliably decodable in both states. In another variant, the capacity condition applies only to the connected state (where the Physical Downlink Shared Channel (PDSCH) data rate is variable).

Abstract

Apparatus and methods for implementing "intelligent" receive diversity management in e.g., a mobile device.. In one implementation, the mobile device includes an LTE-enabied UE, and the intelligent diversity management includes selectively disabling receive diversity (RxD) in that device upon meeting a plurality of criteria including (i) a capacity criterion, and (it) a connectivity criterion. In one variant, the capacity criterion includes ensuring that an achievable data rate associated with a single Rx (receive) chain is comparable to that with RxD.

Description

[0001] priority application [0002] This patent application claims priority to commonly owned and co-pending U.S. Patent Application 13 / 779,661 of the same title, filed February 27, 2013, which in turn claims Priority to US Provisional Patent Application 61 / 606,311, each of which is incorporated herein by reference in its entirety. technical field [0003] This disclosure relates generally to the fields of wireless communications and data networking. More specifically, in one exemplary embodiment, methods and apparatus for managing receive operations in a multi-antenna wireless device or system are disclosed. Background technique [0004] Power consumption is a key factor in the design of modern mobile devices (and indeed other types of devices as well). In the specific context of mobile devices (such as mobile phones, smartphones, tablets, handheld devices, etc.), reducing power consumption can provide a variety of different benefits, including but not limited to enhance...
