    Abstract: A user equipment (UE) may employ Timing Advance (TA) reporting to detect possible error conditions during communication between a base station and the UE. In some instances, the UE receives commands to change a timing advance value. The UE declares an error condition when a timing advance value compared with a reference timing advance value changes more than a threshold amount during a specified time period.

    Abstract: A user equipment (UE) may improve scheduling of inter radio access technology (IRAT) measurement during continuous data transmission, for example in a High Speed-Physical Downlink Shared Channel (HS-PDSCH). The UE may determine whether an IRAT measurement is desired. The UE may also perform the IRAT measurement during a scheduled downlink data subframe when it is determined the IRAT measurement is desired, without losing the scheduled downlink data.

    Abstract: Aspects of the methods and apparatus relate to performing call recovery after a call drop. A cell selection update procedure may be initiated to recover a call in response to the call being dropped with a serving cell. Link conditions may be determined for the serving cell and for different candidate cells. The aspects of the methods and apparatus also include selecting a cell, based on the link conditions, from among the serving cell and a candidate cell with a highest signal power parameter in a Primary Common Control Physical Channel (PCCPCH) across a set of neighboring frequencies of the different candidate cells. Call recovery may be performed using the selected cell. In some aspects, the highest signal power parameter may be a highest Received Signal Code Power (RSCP).

    Abstract: When reporting a channel quality metric, such as a channel quality index (CQI) to a base station, a user equipment (UE) may base its report on a calculated spectral efficiency for allocated data channels. The UE may calculate a spectral efficiency metric over a number of subframes to arrive at an average spectral efficiency measurement which may be converted to CQI and reported to a base station.

    Abstract: The various embodiments provide methods implemented in a multi-RF communication device for managing a victim subscription's de-sense by proactively implementing an RF coexistence management strategy on the victim subscription when an RF coexistence event starts. In various embodiments, a multi-RF communication device may implement an RF coexistence management strategy by determining when an aggressor subscription will de-sense a victim subscription and configuring the victim to anticipate and mitigate de-sense during the aggressor's transmissions. Thus, the various embodiments may provide dramatic improvements to the victim's overall reception performance and overall user experience.
