Abstract: Methods, apparatus, and computer program products for managing mobility in a multi-radio device are provided. One example method generally includes detecting that a first channel is not usable for communicating via a first radio access technology (RAT); receiving a message to redirect from a second channel to the first channel; determining the first channel is in a set of one or more blocked channels not usable for the first RAT; and in response to the determination, taking one or more actions. Another example method generally includes detecting that a first channel is not usable for communicating via a first RAT and providing an indication to a network that a user equipment (UE) no longer supports the first channel.

Abstract: Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

Abstract: Techniques are provided for controlling downlink data transfer during carrier aggregation. For example, a method may control a secondary component carrier downlink (DL) in a wireless communication network using carrier aggregation. The method may include detecting, by a mobile entity, an event indicating a resource constraint at the mobile entity related to a data transmission from a base station to the mobile entity on a secondary component carrier of a carrier aggregation enabled connection. The method may include, in response to detecting the event, controlling the data transmission by signaling a status of the secondary component carrier DL to the base station.

Abstract: Disclosed are methods and apparatus for improving the performance of a user equipment handover during a data call. In one aspect, a source base station determines to handover user equipment (UE) to a target base station. The source base station first determines whether the UE is in a data call prior to the handover. The source base station then modifies one or more of connected mode discontinuous reception (CDRX) and semi-persistent scheduling (SPS) parameters with the UE based on determining to handover the UE and determining that the UE is in the data call.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a probability of occurrence of an event expected to occur within a period of time is determined, where the event comprises one or more of a tune-away event and a suspension event. One or more transmission control protocol parameters are manipulated before the occurrence of the event when the probability of occurrence exceeds a threshold to increase a retransmission time out parameter value, or to maintain a desirable congestion window size. The transmission control protocol parameters may be manipulated by delaying, duplicating or dropping acknowledgements and/or by selectively dropping received packets before, during, or after the event.

Abstract: Method and apparatus are provided that may help improve user experience during a media session when a mobility procedure of a user equipment (UE) involved in the session causes disruption in reception of packets. According to certain aspects, upon detecting an event indicating a mobility procedure is likely to occur, the UE may increase size of a buffer used to store packets during the session and/or reduce the rate at which packets are played out from the buffer to reduce service (e.g., voice/data) interruption.
