  • Patent number: 10999890
    Abstract: A data processing method by a data sending apparatus is described. The method includes receiving a data packet from a PDCP layer, where the data packet is used as an RLC SDU. The method further includes encapsulating the RLC SDU into at least one RLC PDU, where each one of the at least one RLC PDU includes a header and a payload. The payload carries data from a single RLC SDU. It can be learned that a transmit end no longer performs concatenation processing at the RLC layer on the data packet. In this way, concatenation processing at the transmit end is reduced, and processing complexity and processing latency are further reduced. In addition, processing at a receive end also becomes simpler and more efficient.

  • Patent number: 10985896
    Abstract: There is disclosed a method and a network node for handling signals transmitted from one or more wireless devices in a wireless network when Time Division Duplex (TDD) is employed such that two successive uplink subframes of a radio frame are separated by an intermediary time interval. The signals are received during a subframe reserved for uplink transmissions, and a sending time interval with a length of at least a subframe is selected. Then, the received signals are sent to a transport network such that the signals are distributed over the selected sending time interval instead of being sent virtually at the same time as in conventional procedures. Thereby, the signals will be distributed over a longer time when arriving at the transport network which will have time to handle the signals properly such that any loss of packets can be avoided or at least reduced.

  • Patent number: 10958791
    Abstract: A system includes participant nodes that unicast a voice stream to a master node and receive a multicast voice stream from the master node. The multicast voice stream may be a mixed voice stream mixing the voice streams of the participants. In this case, each participant performs echo cancellation on the multicast voice stream. Alternatively, the multicast voice stream may be a multiplexed voice stream multiplexing the voice streams of all participants. In this case, each participant de-multiplexes the multicast voice stream and generates a mixed voice stream that does not include that participant. Alternatively, the multicast voice stream received by each participant may be a multiplexed digital voice stream multiplexing multiple mixed streams including one mixed stream that does not include the voice stream of that participant. In this case, each participant de-multiplexes the multicast voice stream to obtain the mixed stream that does not include that participant.
