Abstract:
A communication system (100) provides, via a serving Node B (123), scheduling information required by a user equipment (UE) (102) to determine a start time for each Node B of multiple Node Bs (120, 123, 126) with respect to a multicast, by each Node B of the multiple Node Bs, of soft combinable MBMS data. The UE may then use the scheduling information to synchronize a soft combining of the MBMS data received by the UE via each of the multiple Node Bs, even when the multicasts via the multiple Node Bs are not synchronized. However, while the multicasts of frames of data associated with an MBMS service by different Node Bs need not be synchronized, synchronized multicasts are preferable for soft combining. Therefore, the communication system further provides for a synchronization by a network controller (130) of the multicasts of the MBMS data by the multiple Node Bs.

Abstract:
A distributed architecture and method for MBMS delivery is disclosed. The various embodiments enable selection combining and soft combining by UEs for MBMS transmissions. An MBMS service notification (509) is sent to all E-Nodes (503). The E-Nodes proceed to request counting (511) from the UEs (501). A transmission request (513) is then sent to the anchor MBMS-Transmission Control Function (TCF) (505) from the E-Nodes (503). The anchor MBMS-TCF (505) generates resource allocation and scheduling profiles and segmentation and reassembly (SAR) profiles for the E-Nodes and sends the profiles (515) to the E-Nodes. The E-Nodes (503) use the profiles for resource allocation and configuration (517) and transmit MBMS data (519) in accordance with the profiles. The anchor MBMS-TCF (505) may then coordinate.
Abstract:
A method and apparatus for providing adaptive bearer configuration for MBMS delivery is disclosed. A first aspect of the present disclosure is a method of operating a wireless infrastructure entity (103) wherein a plurality of common radio resources (303) are allocated for receiving combined responses from a plurality of mobile stations (109). A request message, similar to a request for counting, is broadcast to all mobile stations (109) within a coverage area (105) and may indicate a range, for example a signal-to-noise-and-interference ratio range. Mobile stations (109) responding to the request, use specific resources (303) corresponding to respective range values. The infrastructure (103) may use the received information to determine a modulation and coding scheme for PTM broadcast. The total number of responses to the request message may be limited by providing a probability factor within the request message.
Abstract:
In a telecommunication system (10) for providing multimedia broadcast services to many user equipments (40-45), a physical random access channel (39) is provided for uplink transmission of power control information from the user equipments to a radio site (30, 35). Based upon a comparison of signal-to-noise ratios (53) each particular user equipment sends (55) or inhibits from sending a power control signal to the radio site to which it is coupled. When the radio site of the telecommunication system detects a power control signal (73), the radio site adjusts the transmission power of a broadcast channel intended for reception by multiple user equipments (75) to be incrementally greater than the previous power (81). For lack of detection of a power control signal, adjusts the transmission power of a broadcast channel to be incrementally lower than the previous power.
Abstract:
The need for providing user information to content providers to enable them to authenticate user access to certain content, to perform billing, or to otherwise monitor content use is addressed by embodiments of the present invention. A content delivery server (110) sends service announcement information to user equipment (UE) (101) for a content delivery session of a content provider (120). The service announcement information indicates that user information is requested by the content provider for this session. When the UE user requests to activate the session, the UE obtains the requested user information and sends it with an activation request to the content delivery server. The content delivery server is then able to send the obtained user information, with perhaps additional user information, to the content provider when requesting session activation. The content delivery server activates (subscribes, e.g.) after receiving an indication that activation is approved by the content provider.
Abstract:
A method and apparatus for providing adaptive bearer configuration for MBMS delivery is disclosed. A first aspect of the present disclosure is a method of operating a wireless infrastructure entity (103) wherein a common radio resource (303) is allocated for receiving a response from at least one mobile station (109). A request message, similar to a request for counting, is broadcast to all mobile stations (109) within a coverage area (105. If at least one mobile station (109) responds to the request, PTM transmission mode will be used for MBMS delivery within the given coverage area (105). If more than one mobile station (109) within the coverage area (105) responds to the request, then all the responses will be over the common radio resource (303). The total number of responses to the request message may be limited by providing a probability factor within the request message.
