摘要： Carrier aggregation to enhance Evolved Multimedia Broadcast Multicast Service (eMBMS) includes transmitting unicast signaling for a unicast service on an anchor carrier to mobile entities, transmitting eMBMS signaling on a second carrier different from the anchor carrier to the mobile entities for use with the unicast signaling, and various techniques for practical application of carrier aggregation for eMBMS enhancement. In addition, allocating subframes used for MBMS on a Single Frequency Network (MBSFN) includes allocating at least a portion of one or more subframes otherwise reserved for unicast subframes on a mixed carrier to provide an increased allocation of subframes carrying MBSFN information, transmitting MBSFN signals on the increased allocation of subframes, and more detailed aspects.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines whether the UE is located within a sub-region of an MBSFN area based on one or more parameters. The UE receives based on the determination a service over broadcast in the sub-region of the MBSFN area or over unicast outside the sub-region. In an aspect, the MBSFN area may be smaller than a unicast area. In an aspect, adaptive retransmission with a group NACK approach may be used to improve an SNR and reliability.

摘要： In a wireless communication system a method for combination transmission of packet data and low delay data. In one embodiment a parallel signaling channel provides a message to receivers indicating a target recipient of packet data. The message also identifies the transmission channels used for packet data transmissions. Each receiver may then selectively decode only packets where the message identifies the receiver as a target recipient. The data packets stored in a buffer are ignored if the target recipient is another mobile unit. In one embodiment, the message is sent concurrently with the data packet on a parallel channel. In one embodiment, the message is punctured into the high rate packet data transmission.

摘要： A network entity may dynamically control Quality-of-Service (QoS) for a multicast transmission in a wireless communications system, by initiating a multicast transmission having an initial QoS, and later during the multicast transmission, generating an updated QoS for the multicast transmission. The network entity may generate the updated QoS in response to a network load factor for a multicast area aggregated from base stations in the area. The network load factor may indicate a measure of aggregate available bandwidth in the multicast area. The network entity may provide the updated QoS to mobile entities receiving the multicast transmission, which may process a subsequent portion of multicast content according to the updated QoS.

摘要： Methods and apparatus are presented for dynamically adjusting parameters of an outer-loop algorithm, which is used to determine the feasibility of a transmission format. The parameters of the outer-loop algorithm are adjusted according to channel conditions. In one embodiment, an erasure-based approach is used to determine whether to incrementally increase or incrementally decrease a margin parameter in the outer-loop algorithm. Once one margin parameter is altered, other margin parameters can be adjusted accordingly.

摘要： A method or system for managing demand-based multicast services in a wireless communications system (WCS) capable of both unicast and multicast signaling may include providing content requested by a mobile entity in an area of the WCS via a unicast session, determining that a concurrent demand level for the content exceeds a defined threshold for the area of the WCS, and initiating a multicast session for the content in the area of the WCS, in response to determining the concurrent demand level has exceeded the threshold. The method or system may include more detailed operations or aspects for measuring the concurrent demand level, transitioning signaling between unicast and multicast modes, communicating between network components, or related functions.
