Asymmetrical receivers for wireless communication
First Claim
1. A method, comprising:
- in response to determining that channel state information of a receiver of a set of receivers of a wireless communication device satisfies a first defined condition that is based on a first level of channel quality with respect to a first determined quality of a pilot signal associated with the receiver, scheduling, by a system comprising a processor, a multiple-input multiple-output communication;
in response to determining that the channel state information satisfies a second defined condition that is based on the first defined condition and a second level of channel quality with respect to a second determined quality of the pilot signal, scheduling, by the system, a multiple-input single-output communication; and
initiating, by the system, a first provisioning of a first receiver of the set of receivers corresponding to a first filter associated with a first portion of an electromagnetic radiation spectrum, and initiating a second provisioning of a second receiver of the set of receivers corresponding to a second filter associated with a second portion of the electromagnetic radiation spectrum.

Abstract
Receivers in a mobile device are configured to mitigate receiver overload and fully or nearly-fully utilize available spectrum for communication. Configuration is dictated at least in part by at least one of radio link quality or available receiver specifications, and it can be affected by the mobile device or a base station that serves the mobile device. Receiver configuration includes various spectrally asymmetric receivers that tune respective disparate portions of the available spectrum to maximize utilization thereof in the spectral regions prone to overload conditions. In severe overload conditions, a single receiver can be configured to operate in a frequency band spectrally adjacent to a sub-band that leads to overload conditions when employed for telecommunication. To improve performance, the single receiver configuration can be supplemented with at least one of transmit diversity operation, asymmetric multicarrier spreading, or downlink power boost of asymmetrical multicarrier spreading.

13. A method, comprising:
-
in response to determining that a set of radio link conditions for a set of wireless receivers of a device satisfies a first defined condition that is based on a first signal quality associated with a first characteristic of a pilot signal of a wireless receiver of the set of wireless receivers, initiating, by a system comprising a processor, a first configuration of the wireless receiver according to a multiple-input multiple-output communication mode; in response to determining that the set of radio link conditions satisfies a second defined condition that is based on the first defined condition and a second signal quality associated with a second characteristic of the pilot signal of the wireless receiver, initiating, by the system, a second configuration of the wireless receiver according to a multiple-input single-output communication mode; and initiating, by the system, a first activation of a first wireless receiver of the set of wireless receivers and a second activation of a second wireless receiver of the set of wireless receivers, wherein the first wireless receiver comprises a first filter associated with a first portion of electromagnetic radiation spectrum, and wherein the second wireless receiver comprises a second filter associated with a second portion of the electromagnetic radiation spectrum. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
