20110320790Link Stack Repair of Erroneous Speculative Update - Whenever a link address is written to the link stack, the prior value of the link stack entry is saved, and is restored to the link stack after a link stack push operation is speculatively executed following a mispredicted branch. This condition is detected by maintaining an incrementing tag register which is incremented by each link stack write instruction entering the pipeline, and a snapshot of the incrementing tag register, associated with each branch instruction. When a branch is evaluated and determined to have been mispredicted, the snapshot associated with it is compared to the incrementing tag register. A discrepancy indicates a link stack write instruction was speculatively issued into the pipeline after the mispredicted branch instruction, and pushed a link address onto the link stack, thus corrupting the link stack. The prior link address is restored to the link stack from the link stack restore buffer.12-29-2011

20110319095METHOD AND APPARATUS FOR PERFORMING POSITION DETERMINATION WITH A SHORT CIRCUIT CALL FLOW - For a call flow to perform position determination, a network sends to a user equipment (UE) an indication (e.g., a request for permission) to perform a position fix for the UE. The UE responds by sending to the network an acknowledgment (e.g., a grant of permission) to perform the position fix. The UE selectively sends a position estimate for itself to the network, typically along with the acknowledgment. The network may initiate location processing if (1) a location estimate is not received from the UE or (2) a location estimate is received from the UE but the network decides not to use this location estimate. In this case, the network and the UE perform location processing to obtain a position fix for the UE. However, if a location estimate is received from the UE and the network decides to use the location estimate, then the location processing is bypassed or short circuited.12-29-2011
20110319090Resource Utilization Measurements for Heterogeneous Networks - Interference issues between wireless network devices are mitigated. An evolved node B (eNodeB) may experience higher cell load or higher interference when serving user equipment (UEs) that are operating in an cell range extension (CRE) area in which the UEs are strongly affected by aggressor eNodeBs. An eNodeB experiencing higher cell load or serving user equipments (UEs) under higher interference generally requests an interfering/aggressor eNodeB to repartition some of its resources. Repartitioning of resources, however, may have a negative impact on the eNodeB serving CRE area UEs. In one aspect, a new measurement of utilization accounts for CRE status and differentiates between protected and unprotected resources, such as subframes.12-29-2011

According to the techniques of this disclosure, a client device may communicate a request to a server device to retrieve the at least one I-frame based on the signaled byte range, and use the retrieved I-frame to provide a high speed version of a video presentation that includes the at least one I-frame. A high speed version of a video presentation may be a trick mode of the video presentation, such as a fast forward or fast rewind version of the video presentation.12-29-2011
20110317757INTRA PREDICTION MODE SIGNALING FOR FINER SPATIAL PREDICTION DIRECTIONS - A video encoder selects a prediction mode for a current video block from a plurality of prediction modes that includes both main modes and finer directional intra spatial prediction modes, also referred to as non-main modes. The video encoder may be configured to encode the selection of the prediction mode of the current video block based on prediction modes of one or more previously encoded video blocks of the series of video blocks. The selection of a non-main mode can be coded as a combination of a main mode and a refinement to that main mode.

20110317670TD-LTE HETNET PARTITION - Downlink (DL) subframes and DL hybrid automatic repeat request (HARQ) messages may be protected by time division multiplexing (TDM) partitioning. However, TDM partitioning may not be required for uplink (UL) subframes in general. For example, information carried over a physical uplink control channel (PUCCH), may be protected by frequency division multiplexing (FDM) partitioning. In fact, one UL subframe may correspond to eNBs of multiple power classes. Since TDM partitioning may be required for DL transmissions, one DL sub frame may not correspond to the eNBs of multiple power classes. For some embodiments, groups of subframes may be allocated to the different power classes. Therefore, subframes allocated to an eNB of a power class may observe reduced or no interference from eNBs of other power classes.12-29-2011

In this manner, data is precluded from interfering with the CSI feedback scheme. Consequently, data need not be determined to reliably estimate the channel(s).12-29-2011

20110317642SYSTEM AND PROCESS FOR TRANSMISSION SEQUENCE NUMBER MANAGEMENT IN AN INTRA-NODE B UNSYNCHRONIZED SERVING CELL CHANGE - Various aspects of the disclosure provide an intra-Node B unsynchronized serving cell change enabling the typical loss of packets resulting from such a procedure to be reduced or eliminated. In one example, when a UE ceases listening to a downlink channel from a first cell provided by a Node B and starts to configure its receiver to listen to a downlink channel from a second cell provided by the Node B, a continued incrementing of a sequence number may be stalled in the transmission of packets to the UE. That is, the TSN space may be stalled, such that HARQ retransmissions recur beyond the preconfigured maximum number of retransmissions, until the UE indicates that the serving cell change is complete. In another example, the transmission of packets to the UE from the first cell may be halted until the UE indicates that the serving cell change is complete.12-29-2011
20110317635APPARATUS AND METHOD FOR RECEIVING CELL SYSTEM INFORMATION DURING AUTONOMOUS GAPS - Methods and apparatuses are provided that facilitate receiving signals from one or more base stations while communicating with a serving base station. Devices can receive the signals in autonomous gaps, during which the device can tune away to receive the signals. A device can report a low channel quality indicator (CQI) value to the serving base station prior to the autonomous gap to decrease a likelihood that the base station will schedule transmissions to the device, or at least decrease a data rate for transmissions. In another example, the device can report a CQI reserved for indicating starting an autonomous gap. In either case, the described methods and apparatuses can minimize data loss during the autonomous gap. Once the device returns from receiving the signals, the device can report an improved or actual CQI value to the base station to resume communications.12-29-2011
20110317624METHODS OF CONTROL/DATA PARTITION SCHEME IN HETEROGENEOUS NETWORKS FOR LTE-A - When there are different power classes of base stations (BSs), there may be a need to coordinate transmission from the different BSs to reduce interference to a user equipment (UE) on both control channels and data channels. There are different ways of coordination. For some embodiments, time division multiplex (TDM) resource partitioning may be performed across BSs on a subframe level. TDM resource partitioning may avoid control channel interference since resource mapping on time and frequency for control channels may span the whole frequency domain. However, the data rate for the UE may be limited due to the TDM partitioning of subframes. In other words, a limitation may derive from control channel interference coordination. For some embodiments, a UE may transmit and/or receive in subframes other than the ones partitioned for the UE.12-29-2011
