    Abstract: A packet transmission method, packet transmission apparatus, and an interconnect interface are presented, where the method includes determining, by a sending node, whether an unrecoverable failure occurs in an active link, and if an unrecoverable failure occurs in the active link, selecting, from multiple communication links, at least one standby link except the active link to send a packet to a receiving node, so that the receiving node sends the packet to a receive end of the active link. In the method, for two nodes in an interconnect system that communicate with each other using multiple Links, when it is determined that an unrecoverable failure occurs in some of the Links, packets in retransmission buffers of transmit ends of the links in which the failure is unrecoverable are sent to a standby link.

    Abstract: Embodiments of the present invention relate to a radio link reestablishment method and a controller. The method includes: if after sending downlink signaling or downlink data for designated times, a controller receives no corresponding acknowledgment returned by a user equipment in a cell dedicated channel state, or the controller receives a radio link failure indication message sent by a base station corresponding to the user equipment, the controller instructs the user equipment to re-search for a cell to trigger a cell update procedure, thereby improving reliability of a communications service, and ensuring normal running of the communications service.

    Abstract: A first field of a preamble includes a plurality of indications of respective numbers of spatial or space-time streams for respective receivers to enable each receiver among the multiple receivers to determine a respective set of one or more training sequences, in a plurality of training sequences, that corresponds to the receiver. A second field of the preamble includes respective modulation and coding scheme information for the respective receivers. The preamble is generated such that i) the first field is transmitted prior to the plurality of training sequences, and ii) the second field of the preamble is transmitted after the plurality of training sequences are transmitted. A data portion of the multi-user data unit is generated using respective modulation and coding schemes for the respective receivers. Thee multi-user data unit is transmitted such that data for the respective receivers are transmitted via respective sets of one or more spatial or space-time streams.

    Abstract: A reference signal transmission method and a communications device are described. The method includes determining, by a first communications device, a first frequency band based on a first initial resource index, a second initial resource index, a first configured bandwidth, and a second configured bandwidth. The first initial resource index is greater than or equal to the second initial resource index, and the first initial resource index is less than or equal to a sum of the second initial resource index and the second configured bandwidth. The method further includes receiving, by the first communications device, a reference signal on the first frequency band. When this application is implemented, an actual transmission bandwidth of the reference signal can be accurately determined.
