This application provides a beam training method and apparatus. The method includes: generating and sending a set up frame, where the set up frame includes M pieces of time information, each piece of time information corresponds to one receiving device in the M receiving devices, each piece of time information is used to indicate a feedback information sending moment of the corresponding receiving device, each piece of time information is further used to indicate an acknowledgment information receiving moment of the corresponding receiving device; receiving a sector sweep SSW frame, generating feedback information based on the SSW frame; sending the feedback information at a feedback information sending moment indicated by corresponding time information; receiving, at an acknowledgment information receiving moment indicated by the corresponding time information, acknowledgment information. Therefore, a training time can be shortened and signaling overheads can be reduced.

Beam training method and apparatus

The present invention discloses a method and an apparatus for setting a TCAM entry and relates to the field of communications, which are used to achieve an objective of improving utilization of a TCAM. The method for setting a TCAM entry includes: acquiring a number set formed by values of same fields in preset packets, where the packets are packets on which a same action needs to be performed, and the number set includes at least two numbers; acquiring a longest continuous mask of the number set; obtaining an acquisition result according to the longest continuous mask of the number set; and storing the acquisition result in a ternary content-addressable memory TCAM entry corresponding to the action. The solutions disclosed in the present invention are applicable to a scenario of setting a TCAM entry.
