  • Patent number: 7986664
    Abstract: A method for establishing a connection between user equipment (UE) and an associated network includes receiving at the UE a service announcement providing a description of an available broadcast service and at least one identifier which identifies the broadcast service, and receiving at the UE a setup message which establishes a point-to-point radio bearer between the UE and the network, such that the setup message includes the identifier which is used to identify that the radio bearer carriers the broadcast service.

  • Publication number: 20110080861
    Abstract: A method for communicating between a network and a dual receiver UE includes receiving first signaling from a first network node at a first frequency, and receiving second signaling via a PtM control channel from a second network node at a second frequency. The method further includes receiving a request from the second network node at the second frequency, such that the request is carried on the PtM control channel, and transmitting to the first network node a response to the request from the second network node. An alternative method includes receiving communications from a first network node, and identifying that the first network node lacks uplink capabilities. This method may further include identifying that the first network node provides a MBMS service, and receiving the MBMS service from the first network node despite the identification of the lack of uplink capabilities.

  • Publication number: 20110081912
    Abstract: Methods for allocating and choosing dedicated signatures for random access are provided. Options for allocating dedicated signatures include allocating the dedicated signature from the unused space of the random signature root index when there is unused space and allocating more dedicated signatures from the same root index using the same time/frequency resources if additional signatures are needed, and reserving some preambles from the contention-based random access preambles from both sets of preambles. The present invention also proposes that the dedicated signatures be reserved in each of two sets of preambles.

  • Patent number: 7911969
    Abstract: Wireless communication method for transmitting a status report for a sequence of data transmitted along a wireless communication link between a wireless device and a network having a plurality of base stations, the wireless communication link having a transmitting side and a receiving side. The method comprises: on the receiving side, determining status information on data units of the sequence, indicating whether each data unit has been received or not on the receiving side; and transmitting, from the receiving side to the transmitting side of the wireless communication link, a status report containing a pointer designating a first non-received data unit in the sequence and a bitmap providing the status information for a set of data units following said first non-received data unit in the sequence.

  • Patent number: 7903578
    Abstract: Method for transmitting a status report for a sequence of data transmitted along a wireless communication link between a wireless device and a network having several base stations, said link having a transmitting side and a receiving side. The method comprises: on the receiving side, determining status information on data units of the sequence, including a first set of data units comprising a first non-received data unit in the sequence and data units following said first non-received data unit, the status information indicating whether each data unit has been received or not on the receiving side; and transmitting, from the receiving side to the transmitting side, a status report containing a bitmap providing the status information for a second set of data units included in said first set, such that the bitmap has a predetermined maximum size.

  • Publication number: 20110039590
    Abstract: Transmitting information using a preamble of a Random Access Channel (RACH) in an Evolved Universal mobile Telecommunications System (E-UMTS) is provided. A preamble transmission is used to inform a base station of specific information when a terminal uses a RACH and the base station efficiently allocates radio resources for data transmission to the terminal according to the specific information. Delay time before the terminal transmits data is reduced and unnecessary consumption of radio resources is minimized.

  • Publication number: 20100323736
    Abstract: A method and apparatus to reduce the overhead related to allocation of the terminal identifier in a random access procedure and an optimized method for detecting a collision are provided. By allocating a “short” terminal identifier in the Random Access Response that is identifiers and allocating the permanent terminal identifier at the end of the random access procedure, the size of data that must be transmitted in the Random Access Response is reduced and power is saved.

  • Patent number: 7792130
    Abstract: The method provides buffer status reporting for the transmission of uplink data from a wireless device to a base station. Uncompressed data is stored in a first buffer of the wireless device. A buffer status report is transmitted from the wireless device to the base station, where the buffer status report contains information indicating an amount of the uncompressed data to be transmitted from the wireless device. The information is dependent on the amount of the uncompressed data stored in the first buffer.
