20080310313 | PROTOCOL DATA UNIT RECOVERY - Information can transfer from a transmitter to a receiver; however, the transmission can consume valuable resources. Therefore, a number of times a transmission is attempted can be tracked and compared against a threshold value. If the transmission occurs too many times—based upon the comparison—then a reset can occur. Tracking can occur for a protocol data unit and/or a control protocol data unit to determine if a reset should occur. | 12-18-2008 |
20080310387 | PROTOCOL DATA UNIT PRIORITY MANAGEMENT - A single receiver can collect multiple protocol data units at one time originating from different sources. While it can be desirable for higher priority protocol data units to be processed, loss of data unit portions can cause confusion to the receiver. Therefore, even if a higher priority protocol data unit transfers to the receiver while a lower priority data unit is being processed, the lower priority unit can be completed before processing the higher priority unit; thus, there can be a lower likelihood of confusion among protocol data units. | 12-18-2008 |
20090161545 | 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. | 06-25-2009 |

20140219157 | MANAGING BROADCAST SERVICES - Methods, systems, and devices are described for managing broadcasts of data in wireless communications. A request to join a multicast session is received. A plurality of broadcast technology based identifiers associated with the multicast session are received. Each broadcast technology based identifier identifies one of a plurality of radio access technologies (RATs) broadcasting the multicast session. One of the plurality of RATs is selected. A multicast stream of data associated with the multicast session is received from the selected RAT. | 08-07-2014 |
20140241180 | EVOLVED MULTIMEDIA BROADCAST MULTICAST SERVICE (eMBMS) INTER-FREQUENCY CELL RESELECTION - A method for inter-frequency cell reselection by a wireless communication device is described. The wireless communication device camps on a serving cell. An evolved multimedia broadcast multicast service (eMBMS) service provided by a neighbor cell is discovered. Inter-frequency parameters of the neighbor cell are measured. It is determined whether to perform an inter-frequency cell reselection based on one or more inter-frequency cell reselection factors. An inter-frequency cell reselection to the neighbor cell is performed. | 08-28-2014 |
20140355507 | ADJUSTING PRIORITY OF MBMS AND FEMTO CELLS - A UE may camp on a femto cell in an idle mode and determine whether the UE has an interest in receiving an MBMS service from an MBMS cell. When the UE has the interest in receiving the MBMS service, the UE adjusts a priority of the MBMS cell on which the MBMS service is provided or a priority of the femto cell such that the priority of the MBMS cell is higher than the priority of the femto cell. Otherwise, the UE refrains from adjusting the priority of the MBMS cell or the priority of the femto cell. | 12-04-2014 |
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 |
