  • Patent number: 10070455
    Abstract: A method and apparatus for prioritizing a device-to-device (D2D) transmission and a D2D reception in a wireless communication system is provided. A user equipment (UE), which cannot perform the D2D transmission and the D2D reception at the same subframe simultaneously, detects both the D2D transmission and the D2D reception, which are scheduled at the same subframe, and determines whether to perform either the D2D transmission or the D2D reception at the same subframe.

  • Patent number: 10057029
    Abstract: A cellular multiple-input and multiple-output, MIMO, system (10) comprises a base station (20) having a plurality of antennas (22) and a logic (21) which analyzes pilot signals received from a terminal (11-15) at the plurality of antennas (22) to obtain information about radio channel properties between the terminal (11-15; 100) and the plurality of antennas (22). The base station (20) assigns at least two terminals (11-13) of a plurality of terminals (11-15) to a same pilot time slot. The base station (20) requests at least two terminals (11-13) to transmit pilot signals in the allocated pilot time slot in such a manner that the at least two terminals (11, 12; 11-13) are prevented from transmitting their pilot signals simultaneously.

  • Patent number: 10038652
    Abstract: An N-port, shared-memory switch allocates a shared headroom buffer pool (Ps) for a priority group (PG). Ps is smaller than a worst case headroom buffer pool (Pw), where Pw equals the sum of worst case headrooms corresponding to each port-priority tuple (PPT) associated with the PG. Each worst case headroom comprises headroom required to buffer worst case, post-pause, traffic received on that PPT. Subject to a PPT maximum, each PPT may consume Ps as needed. Because rarely will all PPTs simultaneously experience worst case traffic, Ps may be significantly smaller than Pw, e.g., Ps<(Pw/A) where M>=2. Ps may be size-adjusted based on utilization of Ps, without halting traffic to or from the switch. If Ps utilization exceeds an upper utilization threshold, Ps may be increased, subject to a maximum threshold (Pmax). Conversely, if utilization falls below a lower utilization threshold, Ps may be decreased.

  • Patent number: 9893907
    Abstract: To facilitate management and configuration of VLAN memberships associated with applications or network protocols, a network device receives a packet from a wireless station which is a member of a virtual local area network (VLAN). The network device determines whether the packet is associated with a predefined application or network protocol. If so, the network device delivers the received packet to a dedicated VLAN which is accessible only to network devices associated with the predefined application or network protocol, regardless of destination address specified within the packet. If not, the network device delivers the received packet to an address or a group of addresses specified in a header of the received packet. In some embodiments, the VLAN is divided from a VLAN pool, and the dedicated VLAN corresponds to an address space that is outside the address space of the VLAN pool.

  • Patent number: 9888407
    Abstract: Embodiments may implement a new hierarchical data structure for traffic indication mapping to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames with a partial virtual bitmap based upon the hierarchical data structure for traffic indication mapping. In some embodiments, the MAC sublayer logic may store the traffic indication map and/or the traffic indication map structure in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive, detect, and decode communications with frames comprising the partial virtual bitmap based upon the hierarchical data structure. In some embodiments, indications of buffered data for pages, blocks, sub-blocks, and/or stations may be inverted. In several embodiments, a new association identifier (AID) structure is defined for the new hierarchical data structure for traffic indication mapping.

  • Patent number: 9872182
    Abstract: Methods and system are provided for managing and monitoring allocation of RF spectrum resources based on time, space and frequency. A network may be enabled to allocate excess spectrum resources for use by other network providers on a real-time basis. Allocated resources may be transferred from one provider with excess resources to another in need of additional resources based on contractual terms or on a real-time purchase negotiations and settlements. A network may be enabled to monitor the use of allocated resources on real-time basis and off-load or allow additional users depending on the spectrum resources availability. Public safety networks may be enabled to make spectrum resources available to general public by allocating spectrum resources and monitoring the use of those resources. During an emergency, when traffic increases on a public safety network, the public safety networks may off-load bandwidth traffic to make available necessary resources for public safety users.
