20130201856 | METHOD AND APPARATUS FOR MEDIA ACCESS CONTROL -BASED FAST CELL SWITCHING FOR HIGH-SPEED PACKET ACCESS - Methods and apparatuses for facilitating switching HSPA (high speed packet access) serving cells from each of an RNC (radio network controller), base station, and access terminal are provided. The RNC pre-configures an access terminal and each base station in an active set for HS-DSCH operation by providing identification codes identifying each of the base stations. The RNC transmits data packets tagged with sequence numbers to each base station where they are synchronously buffered. The access terminal initiates a handover by transmitting a PDU (protocol data unit) to each of the base stations. The PDU is encoded with the identification code of a target base station and a sequence number of a subsequent packet. The target receives the PDU and directly completes the handover with the access terminal. | 08-08-2013 |

20140362695 | DOWNLINK FLOW CONTROL - 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. | 12-11-2014 |

20120264416 | SELECTIVE STATE TRANSITIONS OF A USER EQUIPMENT WITHIN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, a user equipment (UE) determines that a client application has entered a period of transmission inactivity whereby the UE will not be required to transmit data on behalf of the client application. The UE selectively transmits a transmission inactivity notification to an access network (AN) to notify the AN of the transmission inactivity period. The AN receives the transmission inactivity notification and determines to transition the UE from a first state to a second state based at least in part on the received transmission inactivity notification, the second state associated with lower-power consumption of the UE than the first state. The AN sends instructions to the UE to facilitate the transition of the UE from the first state to the second state. In another embodiment, the AN can send instructions to the UE to prohibit the UE from sending transmission inactivity notifications. | 10-18-2012 |
20150023240 | COMPRESSED MODE OPERATION AND POWER CONTROL WITH DISCONTINUOUS TRANSMISSION AND/OR RECEPTION - Techniques to support operation in a compressed mode and/or a continuous packet connectivity (CPC) mode are described. In an aspect, a user equipment (UE) may obtain an assignment of enabled subframes for the CPC mode and an assignment of transmission gaps for the compressed mode. The transmission gaps may be aligned with idle times between the enabled subframes. The UE may exchange data during enabled subframes not overlapping the transmission gaps and may skip data exchanges during enabled subframes overlapping the transmission gaps. The UE may make cell measurements during the transmission gaps. In another aspect, the UE may obtain enabled subframes and skipped subframes, exchange data during enabled subframes not corresponding to the skipped subframes, and skip data exchanges during the skipped subframes. In yet another aspect, the UE may receive orders on a shared control channel to quickly enable and disable the compressed mode. | 01-22-2015 |

20140105125 | CRITERIA FOR UE-INITIATED BEARER DEACTIVATION WHEN MAXIMUM NUMBER OF ACTIVE BEARERS HAS BEEN REACHED - A UE determines a need to deactivate one or more bearer contexts. The UE then selects for deactivation one or more active bearer contexts based on a context selection criteria, to avoid exceeding a maximum number of allowable active bearer contexts for the UE. The context selection criteria may relate to one or more of: current usage of active bearer contexts, information from applications associated with active bearer contexts, priority level of applications associated with active bearer contexts, order of active bearer context creation, measure of data activity through active bearer contexts, quality of service associated with active bearer contexts, type of service, e.g. voice or data, for which bearer contexts were activated, bandwidth allocations of active bearer contexts, a criteria predefined by the UE, network or user, or a random selection. Once one or more active bearer contexts have been selected, the UE deactivates the selected active bearer contexts. | 04-17-2014 |
