Abstract:
The present disclosure relates to communication methods and apparatuses. In one example method, a terminal device determines a target time-frequency resource in an uplink communication time period in a target subframe, where the target time-frequency resource is used to transmit an uplink sounding reference signal (SRS) and a physical uplink shared channel (PUSCH). When performing the foregoing communication on the target time-frequency resource, the terminal device simultaneously sends the uplink SRS and the PUSCH to a network device. The uplink SRS and the PUSCH are multiplexed on a same symbol, so that transmission of the uplink SRS and the PUSCH on the same symbol (for example, a same time-frequency resource) can be ensured.
Abstract:
A method for configuring a DHCPv6 client is provided. The method includes: a DHCPv6 client receiving a DHCPv6 advertisement message sent by a network device having a DHCPv6 function, the DHCPv6 advertisement message comprising a management domain identifier of the network device; if the DHCPv6 client does not save the management domain identifier, the DHCPv6 client sending a DHCPv6 request message to the network device; the DHCPv6 client receiving a DHCPv6 response message sent by the network device and completing configuration of the DHCPv6 client. A DHCPv6 client, a network device, and a network system are also provided. Through the technical solution, multiple network devices supporting a DHCPv6 server function can configure the same DHCPv6 client, so as to provide technical support for realizing IPv6 client and network multi-homing.
Abstract:
Embodiments of the present invention provide a method and an apparatus for sending and receiving IPv6 data packets. By adding a new service information extension header to an IPv6 data packet header, or by adding a new service information option in a hop-by-hop options extension header or a destination options extension header of the IPv6 data packet header, embodiments of the present invention are capable of carrying the service information about a service data packet in the IPv6 data packet. In addition, by detecting the service information extension header, or detecting the service information option in the hop-by-hop options extension header or the destination options extension header, embodiments of the present invention are capable of obtaining the service information about the service data packet carried in the IPv6 data packet.
