Abstract: A method and an apparatus for allocating ACKnowledgement (ACK)/Non-ACKnowledgement (NACK) channel resources and processing confirmation information are disclosed. The method includes: The network side determines one physical channel area among multiple physical channel areas to be used by an ACK/NACK channel, and notifies the determined physical channel area to a User Equipment (UE) so as to enable the UE to determine a channel for receiving or sending ACK/NACK information in the determined physical channel area according to a mapping rule. Moreover, the network side may send or receive ACK/NACK information on the physical channel area that includes the ACK/NACK channel. The method and apparatus improve the utilization ratio and flexibility of the ACK/NACK channel, and reduce the probability of conflict generated by the ACK/NACK channel.

Abstract: In various embodiments, uplink scheduling information can be received by a terminal from a network device in a time cell n. The uplink scheduling information can be used to obtain a maximum quantity of first downlink data packets sent by the network device to the terminal device from a time cell n−k3 to a time cell n+k2. Acknowledgement information of the first downlink data packet can be sent by the terminal to the network device on a physical uplink shared channel in a time cell n+k1 based on the maximum quantity of the first downlink data packets. In this way, when the acknowledgement information is sent on the PUSCH, a data reception error caused by a case in which the base station does not know, when decoding the data, a quantity of pieces of acknowledgement information actually sent by the terminal is avoided.

Abstract: In a physical broadcast channel sending/receiving method, after receiving two broadcast channel signals on two corresponding physical broadcast channels at two time-frequency resource locations, the terminal device determines that information other than an offset of a corresponding time-frequency resource location is the same in two pieces of broadcast information carried in the two broadcast channel signals, obtains a time offset difference between the foregoing two time-frequency resource locations, and generates a scrambling code sequence based on the time offset difference; and the terminal device separately descrambles the two broadcast channel signals based on the scrambling code sequence and a preset scrambling code sequence.
