  • Patent number: 9331908
    Abstract: A method implemented by a network component is provided. The method includes receiving a Virtual Station Interface (VSI) Discovery Protocol (VDP) request from an Edge Virtual Bridging (EVB) station and transmitting, to the EVB station, a VDP Response in response to the request. The VDP Response includes a VDP Type-Length-Value (TLV) having a Filter Information field. The Filter Information field is configured to specify a Priority Code Point (PCP) value associated with one or more Virtual Local Area Network (VLAN) Identifier (VID) values carried by the VDP Response. The PCP value is carried in a PCP field and adopted by the EVB station as a default PCP value associated with the VSI and at least one VID. The Filter Information field further contains a PCP Significant (PS) field associated with each PCP field, and wherein the PS field indicates whether the PCP field carries the PCP value.

  • Patent number: 9325480
    Abstract: Disclosed are methods for carrying out device-to-device (“D2D”) communication. In one implementation, a user equipment (“UE”) communicates D2D with another UE using uplink radio resources. The first UE receives a downlink signal from a base station and determines the reception time. The first UE also receives a timing advance for uplink communication. Based on the reception time and the timing advance, the first UE determines an uplink transmission time. When transmitting to the second UE, however, the first UE does not transmit at the determined UL transmission time. Rather, the first UE delays its D2D transmission for a period of time that is based on the second UE's uplink timing advance.

  • Patent number: 9307529
    Abstract: A method is described for receiving a physical signal by a communication apparatus in a wireless communication system supporting carrier aggregation of a first component carrier and a second component carrier. The communication apparatus receives a physical downlink control channel (PDCCH) signal on the first component carrier. The communication apparatus also receives a physical downlink shared channel (PDSCH) signal corresponding to the PDCCH signal on the second component carrier. The first component carrier is different from the second component carrier. A starting orthogonal frequency division multiplexing (OFDM) symbol for receiving the PDSCH signal is determined according to information received via a radio resource control (RRC) signal.

  • Patent number: 9281869
    Abstract: A network repeater is configured to repeat data packets in a broadcast mode without generating a significant broadcast storm. The network repeater is configured to detect a characteristic of a received data packet. The data packet characteristic is compared with valid copies of packet characteristics previously stored in a packet registry. During a delay period, if a valid copy of the detected characteristic is found in the packet registry, then it is assumed that the packet is being received for the second time and the data packet is not repeated in the broadcast mode. If a valid copy of the detected characteristic of the data packet is not found in the packet registry, then the characteristic is stored in the packet registry and the data packet is repeated in a broadcast mode.

  • Patent number: 9277456
    Abstract: The technology described herein relates to a method in a gateway device and a gateway device for handling a context of a UE moving from a source HeNB (220) to a target HeNB. The gateway device is configured to receive a path switch request message from the source HeNB including a first pair of IDs and the gateway device is configured to transmit a second path switch request message to an MME including a second pair of IDs associated to the first pair of IDs. When the gateway device receives a UE context release request message from the source HeNB, the gateway device determines whether IDs in this message are associated to the same second pair of IDs. If this is the case, the gateway device maintains the UE context otherwise the gateway device releases or de-allocates the UE context.
