Abstract: A wireless auxiliary device includes a signal operation module and a filtering module. An electromagnetic characteristic of the signal operation module is adjustable, and an electromagnetic response characteristic of a signal on an operating frequency band is controlled by adjusting the electromagnetic characteristic of the signal operation module. The filtering module is configured to enable an electromagnetic response characteristic of the wireless auxiliary device on a signal on a non-operating frequency band not to be controlled by the signal operation module. The signal on the operating frequency band and the signal on the non-operating frequency band are radio signals transmitted by a base station or a terminal.

Abstract: A method and apparatus for determining a time-frequency resource for Msg1 repeated-transmission includes receiving, by a terminal, a first message sent by a network-side device. The first message carries first configuration information of Msg1 repeated-transmission; determining, by the terminal, a first time-frequency resource for the Msg1 repeated-transmission based on the first configuration information. The determining a first time-frequency resource for the Msg1 repeated-transmission includes at least one of the following determining whether to perform the Msg1 repeated-transmission; determining a physical random access channel (PRACH) resource for the Msg1 repeated-transmission; or determining a frequency hopping parameter of the Msg1 repeated-transmission.
