  • Patent number: 10805831
    Abstract: A method and system to help control CoMP service in a V-RAN arrangement. The load on a cell site's fronthaul network interface between the cell site's RRH and the cell site's BBU is determined. And in response to detecting that the fronthaul load is threshold high, a limit will be imposed on application of CoMP service involving the cell site. For example, in response to detecting that the cell site's fronthaul network interface is threshold highly loaded, (i) the cell site could be made to use decentralized joint processing rather than centralized joint processing, (ii) a lower coverage strength threshold could be imposed as a basis to trigger CoMP service involving the cell site, and/or (iii) the quantity of uplink communication that is subject to CoMP service involving the cell site could be limited.

  • Patent number: 10797761
    Abstract: The present disclosure relates to a method and a device for sending and receiving information. The method includes: determining a frame structure of a serving cell, where a radio frame corresponding to the frame structure includes at least one first special subframe, remaining subframes are downlink subframes, and the first special subframe includes symbols used for uplink transmission and downlink transmission, and a GP; and sending and receiving information in the serving cell based on the frame structure. In the technical solution, because the radio frame structure includes the first special subframe, when spectrum resources are maximally applied to downlink data service transmission, not only performance of massive MIMO is improved, but also the serving cell is enabled to work independently.

  • Patent number: 10785677
    Abstract: Congestion control in a telecommunications network, in which a method of congestion control in a transport network is provided. A buffer state of a buffer is monitored by dynamically sampling the buffer such that the sampling rate is adjusted in dependence of the buffer state. Also, a condition indicative of congestion is determined in response to a change of the buffer state exceeding a predetermined limit. In response to determining the condition indicative of congestion, a congestion notification message is created. The created congestion notification message may then be transmitted to a second network node. The second network node may subsequently compensate for a detected congestion on the basis of a received congestion notification message.

  • Patent number: 10764179
    Abstract: A packet sub-engine coupled to a packet buffer determines which of multiple look up tables (LUTs) is to be searched for a matching entry that matches a received data packet. Each LUT corresponds to a different type of packet handling action and includes multiple entries, each with a match field and a corresponding collection of one or more actions for handling packets that match the match field. The packet sub-engine searches the determined LUT for a matching entry, processes the received data packet according to the action(s) in the matching entry, and determines whether a further LUT is to be searched for a further matching entry. The processed data packet is provided as an output if no further LUT is to be searched, or otherwise the packet sub-engine searches the further LUT and further processes the processed packet according to the action(s) in the further matching entry.

  • Patent number: 10756854
    Abstract: Provided is a terminal device that receives RRC layer information indicating an asynchronous HARQ for a secondary cell, and a first random access response, which is a random access response including fields for indicating an uplink grant and a Temporary C-RNTI and is related to a non-contention based random access procedure on the secondary cell, that manages multiple HARQ processes, and that delivers the uplink grant to an HARQ process that instructs the transmission unit to transmit the MAC layer data in accordance with the uplink grant. In a case that the RRC layer information indicating the asynchronous HARQ is configured, a HARQ process in which the uplink grant included in the first random access response is delivered is determined based on the value of a field for indicating the Temporary C-RNTI included in the first random access response.
