20130194947 | UE-INITIATED DYNAMIC ACTIVATION AND DE-ACTIVATION OF SECONDARY CARRIERS - Managing of secondary carriers for a multicarrier user equipment (UE) is described in which the UE initiates or provides input for activation and deactivation of selected secondary cells in a carrier aggregation depending on allocation or provisioning of UE radio frequency resources. | 08-01-2013 |
20130235843 | ALLEVIATION OF TCP PERFORMANCE DEGRADATION DUE TO CARRIER SUSPENSION OR UE TUNE-AWAY - 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. | 09-12-2013 |
20130303168 | MECHANISM TO IMPROVE DYNAMIC SHARING OF RECEIVE CHAIN(S) AMONG RADIO ACCESS TECHNOLOGIES - Aspects of the present disclosure generally relate to wireless communication and to mechanisms designed to help improve dynamic sharing of one or more receive chains among different radio access technologies (RATs). For example, the mechanisms may be used with LTE and other RATs where Carrier Aggregation is used for simultaneous voice and LTE (SV-LTE) applications. | 11-14-2013 |
20130343265 | METHODS AND APPARATUS FOR ALIGNING VOICE CODER AND SCHEDULING TIMING - The described aspects include methods and apparatus for aligning a voice over data vocoder timing at a user equipment (UE). A scheduling interval timing is determined at the UE, and a timing of a vocoder of the UE can be aligned based on the scheduling interval timing. The UE transmits one or more packets generated by the vocoder according to the timing in at least one transmission period related to the scheduling interval timing. Thus, time delay between packet generation and transmission can be minimized. | 12-26-2013 |
20140016550 | METHODS AND APPARATUS FOR OFFLOADING CHECKSUM PROCESSING - Aspects of the present disclosure provide methods and apparatus for offloading checksum processing in a user equipment (UE) (e.g., from an application processor to a modem processor). Such offloading may speed up packet processing, increase data rate, and/or free up resources of the application processor for other tasks. | 01-16-2014 |
20140335863 | USER EQUIPMENT PANIC STATES(S) UNDER CONNECTED MODE DISCONTINUOUS RECEPTION STATE IN LONG TERM EVOLUTION - Certain aspects of the present disclosure relate to methods and apparatus for wireless communication, and more particularly, to methods and apparatus that utilize one or more user equipment (UE) panic states under connected discontinuous reception (C-DRX) mode in long term evolution (LTE). | 11-13-2014 |
20150063259 | METHOD AND APPARATUS FOR PARTIAL BANDWIDTH CARRIER AGGREGATION - Systems and methods which provide partial bandwidth support of secondary cells for Carrier Aggregation (referred to as Partial Bandwidth Carrier Aggregation) are disclosed. Partial Bandwidth Carrier Aggregation according to embodiments implements wireless links using a plurality of cells with a user equipment (UE), as a means to improve the UE throughput, by using of a portion of the secondary cell bandwidth to accommodate bandwidth limitations of the UE and thereby facilitates the aggregation of component carriers (or portions thereof) when Carrier Aggregation would not otherwise be possible. | 03-05-2015 |

20130201834 | DOWNLINK DATA TRANSFER FLOW CONTROL DURING CARRIER AGGREGATION - 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. | 08-08-2013 |
20130265987 | APPARATUS AND METHOD FOR IMPROVING DEVICE HANDOVER DURING A CALL - 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. | 10-10-2013 |
20150049672 | METHODS AND APPARATUS FOR AVOIDING OR ESCAPING CELL RANGE EXPANSION (CRE) IN A HETEROGENEOUS NETWORK - Certain aspects relate to methods and apparatus for avoiding and/or escaping cell range expansion (CRE) in a heterogeneous network (HetNet). A user equipment (UE) may detect the occurrence of one or more conditions while the UE is in a region of cell range expansion (CRE) in which the UE may be handed over from a first cell of a first power class type to a second cell of a second power class type, the second power class type being lower than the first power class type. The UE may take action to stop being served by the second cell or avoid being handed over to the second cell in response to the detection. | 02-19-2015 |
20150124605 | METHOD AND APPARATUS FOR LTE UPLINK THROUGHPUT ESTIMATION - A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines an observed bit rate based on uplink transmissions of the UE, estimates an available link capacity for the UE, selects an estimate factor, and estimates available uplink throughput for future uplink transmissions of the UE as a function of the observed bit rate, the estimated available link capacity, and the estimate factor. | 05-07-2015 |
20150327249 | UE AUTONOMOUS RADIO RESOURCE CONFIGURATION EXTENSION - Systems, methods, and apparatuses for user equipment (UE) autonomous radio resource configuration extension are provided. As disclosed herein, a UE may operate in dual connectivity with two (or more) base stations, each providing a set of carriers (e.g., cell groups) for wireless communication. The UE may have a simultaneous connection with a carrier from each base station and may autonomously determine a timing difference between carriers of respective cell groups. The UE may adjust the timing of an operation in relation to a radio resource configuration of one or both carriers to account for the difference. In some examples, the UE autonomously adjusts a measurement gap operation or adjusts a discontinuous reception (DRX) operation to account for a determined timing difference between carriers. The autonomous UE timing adjustments may include extending or offsetting a time duration or adjusting one or more subframes in which the operation is performed. | 11-12-2015 |
20150341938 | UPLINK OPERATION FOR RLC COMMUNICATIONS - A user equipment (UE) may have data in a buffer for uplink (UL) transmission. The UE may transmit a buffer status report (BSR) indicating the amount of data. The BSR may fail or a base station may not grant sufficient resources for transmission of the data. A BSR failure condition may be based on a radio link control (RLC) operating mode of the data. For example, the data may be an acknowledgement (ACK) for an acknowledged mode (AM) DL transmission. In this case, the UE may initiate a BSR retransmission (Retx-BSR) timer and determine whether any duplicate transmissions have been received. The data may also be associated with an unacknowledged mode (UM), and the BSR failure condition may include waiting for a time interval that is less than the Retx-BSR time interval. When the BSR failure condition is satisfied, the UE may transmit a scheduling request to the base station. | 11-26-2015 |
