  • Patent number: 9832167
    Abstract: A method for configuring an Internet protocol (IP) address of a small cell includes determining whether the small cell has received authorization from a core network of a mobile operator, determining whether the core network has priority over a local network to connect to the small cell, obtaining a local IP address from a dynamic host configuration protocol (DHCP) function implemented in the small cell or in an access point of the local network of the small cell, and using a core network IP address assigned to the small cell by the core network when the core network has priority over the local network. The small cell determines whether the core network IP address is the same as the local IP address. When the core network IP address is the same as the local IP address, the local IP address of the small cell is changed.

  • Patent number: 9831982
    Abstract: A method and radio node for enabling higher-order modulation in a radio communication with a first UE. A first table configuration comprises at least one of a first Modulation and Coding Scheme, MCS, table and a first Channel Quality Indicator, CQI, table which tables support a certain maximum modulation order. When the radio node detects that a modulation order higher than the maximum modulation order of the first table configuration is potentially possible to use in the radio communication, the radio node instructs the first UE to apply a second table configuration which comprises at least one of a second MCS table and a second CQI table which second tables support the higher modulation order.

    Abstract: Multicasting in Multimedia Broadcast Multicast Service (MBMS) nodes and the respective nodes. The method in a node configured as an MBMS gateway includes, in response to receipt of a session start request message for a multicast session, allocating a transport network IPv4 multicast address and a transport network IPv6 multicast address for the session, and generating another session start request message and transmitting it to a node configured as a Mobility Management Element (MME). The session start request message includes a first pair of the allocated transport network IPv4 multicast address and an IPv4 multicast source address, and a second pair of the allocated transport network IPv6 multicast address and an IPv6 multicast source address. In response to receipt of MBMS data from a node configured as a Broadcast-Multicast Service Center (BM-SC), the MBMS data is sent using at least one of the first and second pair of addresses.

  • Patent number: 9826543
    Abstract: A method and apparatus for determining when to switch between buffer estimation states for a fixed frame rate services session at a terminal. In the event that the state is passive, a network node determines a first time between two received Radio Link Control Service Data Units (RLC SDU). If the first time is lower than a first time threshold, then the state is changed to proactive. When the state is proactive, the network node determines that two consecutive padding transport blocks have been received and further determines that a second time between two padding transport blocks is greater than a second time threshold. If so then the state is changed to passive.

  • Patent number: 9800448
    Abstract: An OFDM transmitter spreads original data symbols with a complex-valued spreading matrix derived from a discrete Fourier transform. Spread data symbols are mapped to OFDM subcarriers. Spreading and mapping are configured to produce a transmitted spread-OFDM signal with a low peak-to-average power ratio (PAPR) and orthogonal code spaces. In MIMO systems, the complex-valued spreading matrix can comprise a MIMO precoding matrix, and the code spaces can comprise MIMO subspaces. In Cooperative-MIMO, a combination of low code-space cross correlation and low PAPR can be achieved.

  • Patent number: 9788286
    Abstract: A method and apparatus for radio link synchronization and power control in CELL_FACH state and idle mode are disclosed. A wireless transmit/receive unit (WTRU) transmits a random access channel (RACH) preamble and receives an acquisition indicator acknowledging the RACH preamble via an acquisition indicator channel (AICH) and an index to an enhanced dedicated channel (E-DCH) resource. The WTRU determines a start of an E-DCH frame. An F-DPCH timing offset is defined with respect to one of the RACH access slot and an AICH access slot carrying the acquisition indicator. A relative F-DPCH timing offset may be signaled to the WTRU and the WTRU may determine a start of an E-DCH frame based on the relative F-DPCH timing offset and timing of an AICH access slot including the acquisition indicator. The WTRU may transmit a dedicated physical control channel (DPCCH) power control preamble before starting an E-DCH transmission.
