Abstract: Adjusting search and measurement periodicity based on device motion. A wireless device may camp on a serving cell. Signal strength, signal quality, and signal to noise ratio of the serving cell may be measured. If each is above a respective threshold, and if the wireless device is stationary, the periodicities at which searches and neighbor cell measurements are performed may be adjusted (e.g., increased) from baseline periodicities.

Abstract: Methods, apparatuses and computer readable media are described that configure wireless circuitry in a wireless communication device. The wireless communication device establishes a connection via one or more component carriers to a wireless network using wireless circuitry that includes multiple radio frequency receive signal chain. The wireless communication device monitors traffic activity and measures downlink radio frequency receive signal conditions for each component carrier. The wireless communication device reconfigures the wireless circuitry to use a number of RF receive signal chains that matches a maximum supportable modulation and coding scheme (MCS) value for each component carrier to MCS values assigned by the wireless network to the respective component carrier. The wireless communication device reduces the number of RF receive signal chains for a component carrier only when reliable decoding of the physical downlink control channel (PDCCH) and/or the physical hybrid automatic repeat request indicator channel (PHICH) can be reliably decoded.

Abstract: A method for assisting a wireless communication device to return to a first network from a second network is provided. The method can include the wireless communication device participating in a CSFB procedure to transition from the first network to the second network for servicing of a voice call; receiving a connection release from the second network after termination of the voice call; initiating a reselection procedure to reselect to the first network; determining presence of packet switched data ready for transmission from the wireless communication device before completion of the reselection procedure; holding the packet switched data at the wireless communication device at least until expiry of a reselection timer initiated during the reselection procedure; reselecting to the first network after expiry of the reselection timer; and initiating transmission of the packet switched data on the first network after completing reselection to the first network.
