摘要： A method and an apparatus for performing verification using a shared key are disclosed. The method includes: receiving, by a first network element, a registration request message from a second network element, where the registration request message includes a user identifier, first network identifier information, and second network identifier information, the second network identifier information is obtained by processing the first network identifier information by using a shared key, and the shared key is a key used between the first network element and the second network element; verifying, by the first network element, the registration request message by using the shared key; and sending, by the first network element, a registration response message to the second network element. When receiving a registration request from a visited network, a home network verifies the registration request message by using a shared key, to avoid a spoofing attack from the visited network.

摘要： Embodiments of this application provide a method and an apparatus for transmitting channel state information (CSI). The CSI is a part of uplink control information (UCI) and it includes a first quantity of bits. The method includes: determining a threshold code rate according to a modulation and coding scheme (MCS) index when the CSI is to be transmitted on a physical uplink shared channel (PUSCH) without uplink data; determining a second quantity of bits according to the threshold code rate and the first quantity of bits, where the second quantity of bits is less than or equal to the first quantity of bits; and transmitting the second quantity of bits of the CSI on the PUSCH.

摘要： This application provides example communication methods, terminal devices, and network devices. One example method includes configuring, by a network device, a first bandwidth part BP and a second BP for a terminal device. The network device then sends a first TB to the terminal device. When the first BP and the second BP correspond to a same physical parameter, the first TB is mapped onto the first BP and the second BP. When the first BP and the second BP correspond to different physical parameters, the network device further sends a second TB to the terminal device, where the first TB is mapped onto the first BP, and the second TB is mapped onto the second BP.

摘要： A secure access method performed by an authentication server includes receiving a first message from a non-3GPP access device. The method also includes performing fast re-authentication with the terminal when determining that fast re-authentication is allowed. The method further includes sending a second message to a home subscriber server. The second message carries a registration type identifier, an identifier of the terminal, and an address of the authentication server. The registration type identifier is used to indicate that current secure access of the terminal is secure access using a fast re-authentication procedure. The method additionally includes receiving a registration success indication from the home subscriber server. The method also includes sending an access success indication to the terminal based on the registration success indication.

摘要： Embodiments of the present disclosure provide an uplink access method, a base station, and user equipment. The method includes: sending, by a base station, N signals and N pieces of physical random access channel PRACH resource indication information, where N is an integer greater than or equal to 2; and receiving, by the base station, a random access preamble sequence of the user equipment on PRACH resources indicated by the N pieces of PRACH resource indication information. Based on the foregoing solution, a quantity of random access preamble sequences sent by the user equipment is reduced, and uplink access complexity is reduced.
