Patent application number | Description | Published |
20130294316 | ACHIEVING FAST EMBMS CHANNEL SWITCHING AND ADDING IN LTE - A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a first MTCH. The apparatus stores MBMS control information for at least a second MTCH. The apparatus subsequently determines to receive the second MTCH. The apparatus then accesses the stored MBMS control information for the second MTCH upon determining to receive the second MTCH. The apparatus receives the second MTCH based on the accessed MBMS control information without acquiring the MBMS control information for the second MTCH after the determination to receive the second MTCH. | 11-07-2013 |
20130294318 | EFFICIENT UPDATE OF TMGI LIST IN LTE EMBMS - A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives at least one MBMS service in at least one MBSFN area. The apparatus receives configuration information on at least one MCCH. The at least one MCCH includes an MCCH unassociated with the at least one MBSFN area. The MCCH unassociated with the at least one MBSFN area is an MCCH associated with an MBSFN area not currently being received by the apparatus. The apparatus constructs a list of TMGIs based on the configuration information. The apparatus updates the list of TMGIs based on at least one of an MCCH change notification message for each of the at least one MCCH or a user service description. | 11-07-2013 |
20140086145 | OPTIMIZED HARQ RECOMBINING WITHIN TRANSMISSION WINDOW - Techniques for optimized HARQ recombining are provided. In one exemplary embodiment, a method for wireless communication comprises receiving a broadcast message to determine a timing of a transmission window, receiving at least one transmission within the transmission window, and determining whether the at least one transmission is successfully decoded. The method further comprises instructing a lower protocol layer to ignore remaining transmissions within the transmission window upon a determination that the at least one transmission is successfully decoded, wherein the remaining transmissions and the at least one transmission comprise duplicate copies of a message segment. | 03-27-2014 |
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 |
20150049600 | PRIORITIZING FREQUENCIES IN EMBMS MULTI-FREQUENCY DEPLOYMENT DURING RLF/OOS - A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE receives, from a serving cell, system information including a plurality of SAIs. The UE determines an interest in receiving an MBMS service from at least one cell on one or more candidate frequencies based on the received SAIs. The UE determines that the UE has encountered one of an RLF or an OOS on the serving cell. The UE prioritizes network reestablishment on the one or more frequencies that carry the MBMS service the UE is interested in receiving upon determining the UE encountered the one of the RLF or the OOS. | 02-19-2015 |
20150063193 | METHOD OF ENHANCING USER EXPERIENCE BY USING SYSTEM INFORMATION IN LTE EMBMS - A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a request to receive a Multimedia Broadcast Multicast Service (MBMS) service associated with a service area identity (SAI) and a second frequency. The apparatus performs inter-frequency cell reselection from a first cell transmitting at a first frequency to a second cell transmitting at the second frequency, the second cell being an inter-frequency neighbor cell to the first cell. The apparatus receives system information from the second cell. The apparatus determines that the second cell transmitting at the second frequency is unassociated with the SAI based on the received system information. The apparatus blacklists the SAI on the second frequency in a blacklist for at least a period of time upon determining that the second cell is unassociated with the SAI. | 03-05-2015 |
20150105066 | ADDRESSING RADIO LINK FAILURES IN WIRELESS COMMUNICATION SYSTEMS - Methods and apparatus for enhanced radio resource control (RRC) reestablishment in a communication system include addressing repeated radio link failures (RLFs). For example, the methods and apparatus include incrementing a counter value associated with a first cell based on a detection of a RLF by a user equipment (UE) in a RRC connected state with the first cell. The methods and apparatus further include determining that the counter value meets or exceeds a first barring threshold value within a cell barring evaluation time duration. Additionally, the methods and apparatus include prohibiting the UE from performing an RRC reestablishment procedure with the first cell for a first barring time duration. | 04-16-2015 |
20150146694 | PRUNING A CANDIDATE CELL LIST FOR AN IDLE MODE UE AND A CONNECTED MODE UE - A method for determining candidate radio access technology (RAT) layers includes selecting one or more initial candidate RAT layer, for each configured RAT type of a UE, for a target RAT candidate list. The target can be for redirection or handover, for example. Each initial candidate RAT layer is selected regardless of network indicated RAT priorities and measurement object IDs. The method also includes selecting additional candidate RAT layers, for the list, based on the network indicated RAT priorities or the measurement object IDs. The method may be specified for when a UE is in a connected mode or an idle mode. | 05-28-2015 |
