Methods and apparatus for adaptive receiver diversity in a wireless network

摘要

Apparatus and methods for implementing “intelligent” receive diversity management in e.g., a mobile device. In one implementation, the mobile device includes an LTE-enabled 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 (ii) 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.

1. A method for intelligently performing adaptive receive diversity, the method comprising,
at a mobile device:
determining a connectivity condition;communicating via a wireless receiver, the wireless receiver configurable in at least a first diversity-enabled scheme and a second diversity-enabled scheme;wherein the first diversity-enabled scheme supports a higher data capacity than the second diversity-enabled scheme;comparing a current connection quality to the connectivity condition;when operating in the first diversity-enabled scheme: when the current connection quality satisfies the connectivity condition, transitioning to the second diversity-enabled scheme; and when operating in the second diversity-enabled scheme: when the current connection quality does not satisfy the connectivity condition, transitioning to the first diversity-enabled scheme.
