20140119264 | PRIMARY CELL SIGNALING FOR EMBMS IN CARRIER AGGREGATION - A method, an apparatus, and a computer program product for wireless communication are provided. In a first configuration, the apparatus is an eNB. The eNB constructs an MCCH change notification, and sends the MCCH change notification with a carrier frequency index for a first frequency of a first cell on a second frequency of a second cell. In a second configuration, the apparatus is a UE. The UE receives a configuration with aggregated carriers including a primary carrier from a primary cell and one or more secondary carriers from one or more corresponding secondary cells, and receives an MCCH change notification with a carrier frequency index for a first frequency of a first cell on a second frequency of a second cell. The first cell and the second cell are each one of the primary cell and the secondary cells. | 05-01-2014 |
20140119265 | MULTIBAND EMBMS ENHANCEMENT USING CARRIER AGGREGATION - A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE receives at least one of a unicast or a broadcast/multicast communication on a first frequency from a first cell of a serving eNB through a first receive chain. In addition, the UE receives at least one of broadcast/multicast signal, synchronization signal, or reference signal communication on a second frequency from a second cell of the serving eNB through a second receive chain without having received instruction from the serving eNB to receive the at least one of the broadcast/multicast signal, the synchronization signal, or the reference signal communication. | 05-01-2014 |
20140126454 | EMBMS SUPPORT IN HETEROGENEOUS NETWORK - A method, an apparatus, and a computer program product for wireless communication at a node are provided. The apparatus receives a multicast-broadcast single frequency network (MBSFN) signal transmitted from a base station, decodes the received MBSFN signal, and retrieves at least one source symbol from the decoded MBSFN signal when the node is capable of retrieving a source symbol. The apparatus also generates at least one redundancy version of the MBSFN signal based on the retrieved at least one source symbol and transmits the at least one redundancy version of the MBSFN signal via MBSFN. Generating a redundancy version of the MBSFN signal includes applying forward error correction (FEC) on the retrieved at least one source symbol to generate at least one repair symbol. Thus, a redundancy version of the MBSFN signal includes the at least one repair symbol and a subset of the at least one source symbol. | 05-08-2014 |
20140134970 | EMERGENCY ALERT USING MBMS AND CELL BROADCASTING - An emergency notification service is described that is delivered using an evolved multimedia broadcast-multicast service (eMBMS). An emergency notification is sent out to user equipment (UE) in affected areas. In response to receiving the emergency notification, the UE searches the appropriate emergency multicast service acquisition information for multiple potential types of available emergency content that is provided by the eMBMS system in the network and tunes to the eMBMS to receive the emergency content. In selected aspects, the transmitted information, including the notifications and content may be scrambled using the same cell ID for each of the cells transmitting the same content. This improves the quality of the transmitted signals allowing for more reliable receipt and decoding by the receiving UEs. | 05-15-2014 |
20140153471 | ALLOWING UNICAST SUBFRAME STRUCTURE FOR EMBMS - A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a multicast/broadcast single frequency network (MBSFN) subframe configured based on a unicast subframe structure, and transmits MBSFN signals for eMBMS using the MBSFN subframe. In a one configuration, the MBSFN subframe structure for eMBMS transmissions uses the same CP length, the same common reference signal (CRS) pattern and same subframe structure used for unicast, along with the same antenna ports used for unicast transmission. In another configuration, the MBSFN subframe structure for eMBMS transmissions uses the same CP length and same subframe structure used for unicast, but potentially different CRS patterns and different antenna ports from those used for unicast transmissions. In another configuration, the MBSFN subframe structure for eMBMS transmission uses the same CP length and same subframe structure used for unicast, but with a UE-RS pattern. | 06-05-2014 |
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 |
