  • Patent number: 11071040
    Abstract: Embodiments of the present invention provide a D2D communication method and a D2D device. The method comprises: a first terminal device determines information to be forwarded, the information to be forwarded comprising target information and forwarding condition information; and the first terminal device sends the information to be forwarded, such that when receiving the information to be forwarded, a second terminal device determines, according to the forwarding condition information, whether to forward the information to be forwarded. In this way, congestion caused by a large amount of information forwarding is avoided by filtering terminal devices available for information forwarding and enabling a terminal device meeting particular conditions to forward information to be forwarded, thereby avoiding congestion caused by forwarding of a large amount of information.

  • Patent number: 11064554
    Abstract: To provide a radio communication device and a radio communication method that can surely avoid a state that communication cannot be started because of a disagreement in states in an intermediate layer, which is lower to RRC layer, when transitioning between a connected state (RRC-Connected) and a suspended state (RRC-Suspended) in the RRC layer. UE (100) includes a state controlling unit (120) that controls the RRC layer to be in the connected state or the suspended state, and an interruption processing unit (130) that initializes at least a part of states in the intermediate layer, specifically MAC layer/RLC layer/PDCP layer, after the RRC layer has transitioned from the connected state to the suspended state. The state controlling unit (120) causes the RRC layer to resume from the suspended state to the connected state based on the state of the intermediate layer initialized by the interruption processing unit (130).

  • Patent number: 11051263
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a first synchronization sequence and generate a second synchronization sequence based at least in part on the first synchronization sequence. The base station may map the first synchronization sequence to a first resource block of a synchronization channel associated with a first frequency sub-band of a shared radio frequency spectrum band and the second synchronization sequence to a second resource block associated with a second frequency sub-band of the synchronization channel. The base station may then transmit the first synchronization sequence and the second synchronization sequence concurrently over the synchronization channel using the first resource block and the second resource block according to the mapping. In some cases, the second synchronization may be generated by applying a first phase shift to the first synchronization sequence.

  • Patent number: 11019545
    Abstract: A connection between two UEs is identified by a single connection identifier. Different streams are transmitted over different wireless links with potential redundancy between streams. Initially a first WiFi link is used to communicate with the second UE. After the first UE decides it will handoff to a second WiFi AP it establishes a connection with a cellular AP and then communicates a second stream corresponding to the same connection. The first and second streams initially communicate the same content. The first WiFi link is terminated, but the second stream continues to communicate content. The first UE then establishes a second WiFi connection with a second WiFi AP and communicates a third content stream of the first connection to second UE via second WiFi link. The third stream initially communicates information also communicated over second stream. The cellular link is terminated. The second WiFi link is used to communicate content.

  • Patent number: 10999806
    Abstract: Methods and apparatus which allow a wireless terminal (302) to simultaneously maintain connections with multiple base stations (304, 306) are described. Each wireless terminal (302) is capable of supporting multiple separate timing and/or other control loops one, for each base station connection thereby allowing the connections to operate independently and in parallel. Different control signals and/or data are transmitted on each connection that is established with a base station (302, 306). In this manner base stations (302, 306) receive different data allowing for asynchronous data transmission. The data received by the base stations (302, 306) can be supplied to a wired asynchronous network (308) without the need to combine the received data prior to supplying it to the wired network (308). The communications techniques of the invention can be used to implement soft handoffs without the need to duplicate data transmissions to multiple base stations.

  • Patent number: 10999206
    Abstract: Systems and methods for controlling congestion of a data network are provided. An engine round-trip time (RTT) and a fabric RTT for a network flow are determined. An engine-based congestion window size for the flow is determined based on the engine RTT and a target engine RTT. A fabric-based congestion window size for the flow is determined based on the fabric RTT and a target fabric RTT. The smaller of the engine-based congestion window size and the fabric-based window size is selected for use in transmitting a future packet associated with the flow. The target engine RTT is determined based in part on the current congestion window used to transmit packets for the flow and/or the target fabric RTT is determined based on a number of hops packets associated with the flow traverse from a source to a destination associated with the flow.

  • Patent number: 10986689
    Abstract: A method, mobile device (101) and radio access network RAN (102) are disclosed for suspending and re-establishing a radio resource control (RRC) connection. In some examples, the mobile device (101) indicates a preference to have the RRC connection either suspended or released. In other examples, RAN (102) sends to the mobile device (101) a connection suspend command message instructing the mobile device to suspend a RRC connection with the RAN (102). The mobile device (101), in response to the connection suspend command message, suspends the RRC connection. When the RRC connection is suspended the mobile device (101) cannot transmit or receive user plane data to the RAN (102) and performs functions the same as or similar to idle mode functions. On suspension, RRC connection information is stored and can be used to re-establish the suspended RRC connection.
