摘要： A method and apparatus for neighbor assisted combining for localized multicast services. Cells (112) are determined (420) in which user equipment (120) reside that desire a common multicast service. At least one serving cell for transmitting the common multicast service is selected (430) based on the determination. At least one extended serving cell is selected (440) from at least one serving cell neighbor cell (114) which wherein no user equipment reside that desire the common multicast service, transmissions on the extended serving cell influencing transmissions on the serving cell. The common multicast service is transmitted (470) on the selected at least one serving cell.

摘要： A dynamic shared forward link channel (or 'data' channel) is used to send multicast data to a group of wireless devices, e.g., using a common long code mask for the data channel. Reference power control (PC) bits are also sent on the data channel and used for signal quality estimation. A shared forward link control channel is used to send user-specific signaling to individual wireless devices, e.g., using time division multiplexing (TDM) and a unique long code mask for each wireless device. A shared forward link indicator channel is used to send reverse link (RL) PC bits to the wireless devices, e.g., using TDM. The data channel is jointly power controlled by all wireless devices receiving the data channel. The control and indicator channels are individually power controlled by each wireless device such that the signaling and RL PC bits sent on these channels for the wireless device are reliably received.

摘要： Group communications methods and apparatus (700) are described. Multiple modes of group communications signaling are supported. In a first mode (706), copies of packets are separately transmitted to each group member in a sector or cell. In a second mode (712) a copy of a packet is directed to multiple group members at the same time. Transitions between the two modes may be determined as a function of the cost of operating in each of the modes (708) in terms of system cost and/or the number of group members (704) in a cell or sector being serviced by a transmitter.

摘要： A communication system (100) is provided that dynamically allocates power to a Multimedia Broadcast/Multicast Service (an MBMS service). In response to determining (304) to establish a Point-to-Multipoint (PTM) communication channel to multiple user equipment (UEs) (102-104), the communication service assigns (306) the PTM communication channel to the MBMS service, determines (308) a power requirement associated with each user equipment (UE) of the multiple UEs based on a handover quality measurement associated with the UE to produce multiple power requirements, and allocates (310) a power level to the PTM communication channel based on the multiple power requirements. The communication system further dynamically adjusts the allocated power based on a handover quality measurement associated with a UE of the multiple UEs that is received during provision of the MBMS service.

摘要： The power level of multicast data transmissions in a wireless communications network are controlled. Power level information is provided in a transmitted channel received by a user equipment. The user equipment measures the power level of a received signal. It compares the measured power level to the power level indicated by the power level information provided in the transmitted channel. Power level measurement information is included in a message sent by the user equipment depending on the results obtained when the power level measured by the user equipment is compared to the power level indicated by the power level information provided in the transmitted channel.

摘要： An apparatus and method for providing a multimedia broadcast/multicast service (MBMS) service between an RNC (140) and a Node B (150) in a mobile communication system including multiple UEs, the Node B having multiple cells, and the RNC for controlling the Node B. The RNC (140) transmits a request message including first information that can be determined according to services and second information that can be determined according to cells, to the Node B (150) in order to support the MBMS service. The Node B (150) generates a service context for providing an MBMS service according to the first information and the second information of the request message, and allocates identification information of the service context. The Node B sets up a transport bearer to the RNC according to the first information in the service context, and then, if the MBMS service data is received from the RNC (140) over the transport bearer, transmits the received MBMS data to the respective cells so that the UEs receive the MBMS data.
