  • Patent number: 9253790
    Abstract: Radio blocs (BRjp) shared in a predetermined frequency band during a periodic radio frame (TRi) between base stations (BS) are allocated to applications in base stations and mobile stations. Each radio block spreading on frequencies (Cj) of said band during a time slot (M?t) of the radio frame and can be associated with an uplink or a downlink. To meet quality-of-service parameters required by an application, a base station estimates occupation rates of the radio blocks during consecutive radio frames, and allocates to the application at least one radio block having an occupation rate less than a threshold and a periodicity expressed in period of frame and depending on the required quality-of-service parameters. The base station are autonomous for the radio block allocations.

  • Patent number: 9215078
    Abstract: The present invention provides a multicast method and a multicast device. The method includes: receiving a multicast request from a user, where the multicast request includes multicast channel information and a user VLAN tag; selecting a first target multicast VLAN from pre-configured multiple multicast VLANs; after replacing the user VLAN tag in the multicast request with the first target multicast VLAN tag, forwarding the multicast request to a multicast router; receiving multicast traffic sent by the multicast router through the first target multicast VLAN, and forwarding the multicast traffic to the user. In the present invention, a target multicast VLAN is selected according to multicast channel information, so that multicast requests for the same multicast channel can be added to the same multicast VLAN. In this way, only one copy of multicast traffic of the same channel exists on a local area network, thereby saving network bandwidth resources.

  • Patent number: 9198189
    Abstract: A wireless communication apparatus is capable of improving communication efficiency by reducing the amount of control information transmitted. A channel quality information extraction section extracts CQI's from a received signal. An allocation control section allocates subcarriers for every communication terminal apparatus and selects a modulation scheme in such a manner that required transmission rate is satisfied for each communication terminal apparatus based on required transmission rate information, etc. and CQI's for communication terminal apparatus of each user. A required subcarrier number determining section decides the number of subcarriers allocated to every communication terminal apparatus so as to satisfy the required transmission rate for each communication terminal apparatus. A required subcarrier number information generating section generates information for the number of subcarriers allocated to every communication terminal apparatus.

  • Patent number: 9178639
    Abstract: A technique for receiving and transmitting downlink reference signals is disclosed. When transmitting downlink data demodulation reference signals (DMRS) (or reference signals for downlink data demodulation) by using two or more layers, the DMRS of each layer may be multiplexed by using a code division multiplexing method and then transmitted. The DMRS for each of the two or more layers may be used for one user equipment or for two or more user equipments. And, downlink control signals for transmitting and receiving such DMRS may be configured to have the same format regardless of a single-user mode (or SU-MIMO mode) or a multi-user mode (or MU-MIMO mode), thereby being used.

  • Patent number: 9025610
    Abstract: The present invention provides a method for a MTC group selecting a Packet Data Network Gateway (PGW) and a mobility management network element. After a MTC UE in the MTC group attaches for the first time, PGW information corresponding to the selected PGW is stored in a subscriber database; and when other MTC UEs in the MTC group attach, the PGW corresponding to the PGW information stored in the subscriber database is directly used as their own PGW. With the method of the present invention, it is guaranteed that the PGWs selected by multiple MTC UEs belonging to the same MTC group are the same PGW, thereby guaranteeing that the maximum flow and charging of each MTC group are effectively limited subsequently.
