Abstract: A communication method and apparatus, a storage medium, and a chip system relate to the field of communication technologies, to reduce a bit error and/or a packet loss. In this application, a terminal device receives configuration information from a network device, where the configuration information is used to configure a first carrier. The terminal device sends first information to the network device. The first information indicates to stop data transmission on the first carrier. The first information further indicates that the terminal device stops measurement on the first carrier. Therefore, the network device may determine that a reason for receiving no measurement result of the first carrier from the terminal device is that a first terminal device does not measure the first carrier, rather than another reason, and then the network device can activate a carrier more properly.

The first time window may be a time window where the terminal occupies the unlicensed band. The base station may transmit a first random access feedback is transmitted through the first control channel. The first random access feedback may indicate that the base station receives the random access preamble.

Abstract: A communication method and apparatus are provided. The method includes: A first device receives first information, where the first information includes phase information of a second device on M resources, and the M resources are frequency resources. The first device receives a first signal from the second device on one or more of the M resources.

This reduces interference caused by a difference between phases of different signals, to improve accuracy of the obtained measurement information.
