Abstract: A method and apparatus of selecting which of a plurality of receiver chains of a mobile unit to receive wireless signals, is disclosed. One method includes measuring a first receive signal quality while all of the plurality of receiver chains are receiving wireless signals, and measuring a second receive signal quality while a subset of the plurality of receiver chains are receiving wireless signals. The subset of the plurality of receiver chains are selected to receive wireless signal unless the first receive signal quality is a threshold better than the second receive signal quality. If the first receive signal quality is a threshold better than the second receive signal quality then all the plurality of receiver chains are selected to receive wireless signals.

Abstract: A method for managing uplink communication in a wireless communication network is provided. The method includes selecting one or more Mobile Stations (MSs) from a plurality of MSs based on a first signal parameter corresponding to each MS of the one or more MSs, one or more second signal parameters corresponding to each MS of the one or more MSs, and one or more threshold parameters. The first signal parameter is associated with a Base Station (BS) serving a MS. Further, the one or more second signal parameters are associated with one or more BSs neighboring to the MS. The one or more threshold parameters are associated with a communication parameter. Thereafter, the method includes modifying an uplink Modulation and Coding Scheme (MCS) level of the one or more MSs.

Abstract: Provided are various implementations of a wireless network synchronization solution. In one implementation, such a solution includes a mobile communication device including a receiver for use with the wireless network. The receiver is configured to receive a downlink communication from the wireless network, to detect a primary synchronization signal (PSS) at a PSS subframe symbol of the downlink communication, and to detect a secondary synchronization signal (SSS) at an SSS subframe symbol of the downlink communication. The receiver is further configured to identify the downlink communication as being duplexed using one of a first duplexing mode and a second duplexing mode when the PSS subframe symbol follows the SSS subframe symbol, and to identify the downlink communication as being duplexed using the other of the first duplexing mode and the second duplexing mode when the PSS subframe symbol precedes the SSS subframe symbol.
