Abstract: A system and method for recovering missed Multimedia Broadcast and Multicast Service (MBMS) data frames in a Multicast Broadcast Single Frequency Network (MBSFN) is provided. The method includes storing a first set of Service Data Units (SDUs) in a first Radio Link Control (RLC) buffer, wherein the first set of SDUs is broadcasted using a first set of MBMS data frames from a first eNB, storing a second set of SDUs in a second RLC buffer, wherein the second set of SDUs is broadcasted using a second set of MBMS data frames from a second eNB, and comparing the first set of MBMS data frames associated with the first set of SDUs with the second set of MBMS data frames associated with the second set of SDUs to recover the missed MBMS data frame in the first set of RLC SDUs received from the first eNB.

Abstract: Some example embodiments provide a method performed by a dual subscriber identification module (SIM) dual standby (DSDS) controller for efficiently sharing radio frequency (RF) resources in a DSDS device, the method comprising: receiving, when a data session is ongoing in a first SIM, a request from a second SIM for access to the RF resources for performing an activity at the second SIM having higher priority than the data session; determining a scaled throughput for the first SIM; determining an RF rejection percentage for the second SIM based on the scaled throughput; and providing the second SIM with access to the RF resources based on the RF rejection percentage.

Abstract: A method for providing IDLE mode multimedia broadcast multicast service (MBMS) continuity in a telecommunication network is provided. The method includes providing an MBMS of interest for a user equipment (UE) from a first cell in the telecommunication network, using an MBMS gateway, performing a cell re-selection measurement of at least a second cell using the UE, the second cell being a neighboring cell to the first cell, wherein the cell re-selection measurement comprises determining a configuration of the second cell to facilitate an MBMS and determining a signal strength matching a predetermined strength value, and selecting one of the first cell and the second cell using the UE, which is configured to facilitate the MBMS and has a signal strength value at least equal to the predetermined strength value and greater than the other cell.

Abstract: The present invention provides methods for improving performance and reducing power consumption in a dual subscriber identification module (SIM) dual standby (DSDS) device. According to one example embodiment, the DSDS device enhances the usage of a single RF resource to be shared between a first SIM and a second SIM of the DSDS device based on one or more entry and exit conditions. The DSDS device allows the first SIM to use the RF resource for a data session while it restricts the second SIM from performing neighbor cell measurements when entry conditions are met. By restricting the neighbour cell measurement operations on the second SIM, the DSDS device enables the first SIM to use the RF resource for an extended time thereby improving data rates in the DSDS device. Further, the DSDS device allows the second SIM to perform neighbor cell measurements when the exit conditions are met.

Abstract: A method of and User Equipment (UE) for enhancing reporting information for a Radio Link Failure (RLF) in a Long Term Evolution (LTE) network. The method includes receiving, by a User Equipment (UE), RLF threshold information transmitted from the LTE network, logging, by the UE, the RLF threshold information, and indicating, by the UE, a recovery from a near RLF condition.
