One method includes: obtaining an interference degree that is caused when a site device performs full-duplex transmission with at least two UEs; and determining, according to the interference degree, a UE allowed to transmit uplink and downlink signals on the same time and frequency resource among the at least two UEs. In embodiments of the present invention, a UE allowed to transmit uplink and downlink signals on the same time and frequency resource may be classified according to an interference degree that is caused when a site device performs full-duplex transmission with at least two UEs, thereby preventing the interference problem in the scenario of point-to-multipoint full-duplex communication as much as possible.

Abstract: User equipment receives at least one TAC that is broadcast by a network device, where the TAC includes geographical location information, and the geographical location information is used to indicate a geographical location of a preset location point in a TA corresponding to the TAC. The user equipment determines, based on the TAC and a tracking area list (TAL), whether the TAL needs to be updated. If it is determined that the TAL needs to be updated, the user equipment sends a tracking area update request to the network device. The user equipment receives a response message, of the tracking area update request, returned by the network device.

Abstract: A channel encoding method and apparatus. The method includes: obtaining A to-be-encoded information bits; mapping the A to-be-encoded information bits and L CRC bits to a first bit sequence based on an interleaving sequence, where the L CRC bits are obtained based on the A to-be-encoded information bits and a CRC polynomial, the interleaving sequence is obtained from a prestored interleaving sequence table or is obtained based on a maximum-length interleaving sequence, A+L is less than or equal to Kmax, and Kmax is a length of the maximum-length interleaving sequence; and encoding the first bit sequence. In this way, not only an encoding delay can be reduced, but also decoding has an early stop capability, so that decoding can end in advance, thereby reducing a decoding delay.
