    Abstract: Example information transmission methods and apparatus are described. One example method includes receiving higher layer signaling and downlink control information. A time-frequency resource corresponding to scheduling request (SR) information and a time-frequency resource corresponding to hybrid automatic repeat request (HARQ) information are respectively determined based on the higher layer signaling and the downlink control information; The SR information is sent by using a first time-frequency resource, and the HARQ information is sent by using a second time-frequency resource. The first time-frequency resource is a part of the time-frequency resource corresponding to the SR information and does not overlap the second time-frequency resource in time domain, and the second time-frequency resource is the time-frequency resource corresponding to the HARQ information. Alternatively, the HARQ information is sent by using the time-frequency resource corresponding to the HARQ information, where the SR information is not sent.

    Abstract: An Internet Protocol Security (IPsec) acceleration method includes generating, by an Internet Key Exchange (IKE) device, an IKE link establishment session packet according to an IPSec configuration parameter and a security policy in a security policy database (SPD), sending, by the IKE device, the IKE link establishment session packet to a peer device, establishing a security association (SA) with the peer device, and sending, by the IKE module, the SA to a data forwarding device, where the IKE device and the data forwarding device are discrete devices.

    Abstract: A service deployment method and a network functions acceleration platform are provided. The method includes: when an FPGA is powered on, loading, by the FPGA, an FPGA framework file, so that the FPGA includes M partial reconfigurable PR areas, a configuration module, and a data flow forwarding module; when receiving a service configuration instruction, generating, by a physical machine, a VM, and selecting at least one PR area from the M PR areas to establish a correspondence with the VM; performing, by a configuration module, service resource configuration on the selected PR area according to a PR configuration resource, so that the selected PR area has a service processing capability; adding, by the configuration module, a forwarding entry corresponding to the PR area in a forwarding flow table, so that the data flow forwarding module forwards a received network packet to the corresponding PR area.

    Abstract: A terminal device receives first information including an acknowledgment resource indicator (ARI), and determines, based on the ARI, a first uplink control channel (PUCCH) resource in a PUCCH resource set corresponding to a payload size of a hybrid automatic repeat request acknowledgment (HARQ-ACK). In a case that the first PUCCH resource and a second PUCCH resource partially overlap in terms of time; or the first PUCCH resource and a second PUCCH resource configured for CSI do not overlap in terms of time, and the first PUCCH resource and the second PUCCH resource each partially overlap at least one third PUCCH resource configured for at least one positive scheduling request (SR) in terms of time, the terminal device determines, based on the ARI, a fourth PUCCH resource in a second PUCCH resource set corresponding to a total payload size for sending the HARQ-ACK, CSI, and at least one SR status.
