A method for performing tune away in a wireless communication device includes: tuning away the wireless communication device from a first communication network for a first tune away period to receive a first page burst from a second communication network, and during the first tune away period sequentially tuning to a plurality of neighbor cells of the second communication network and performing signal quality measurements on signals received from each of the plurality of neighbor cells.

Efficient WCDMA to GSM tune away pattern

Apparatus and methods are disclosed to provide for a multi-SIM wireless user equipment configured for block-level, or slot-level tune-away operations enabling simultaneous communication with a plurality of channels. The first and second channels may correspond to different RANs, each of which the user equipment may subscribe to as corresponding to information in a plurality of SIMs at the user equipment. In other examples, the first and second channels may correspond to different cells within a single RAN. In either case, the tune-away operations disclosed provide for reduced data loss at the first channel and in some examples improved communication performance at the second channel. Other aspects, embodiments, and features are also claimed and described.
