Abstract: A communication method and apparatus are provided. The method includes: receiving configuration information from a network device, where the configuration information indicates an occasion and/or a period for sending a measurement signal on a second uplink carrier; obtaining signal quality or signal strength on a downlink carrier associated with a first uplink carrier, or signal quality or signal strength on a downlink resource on a first uplink carrier; and when a first condition is met, sending the measurement signal on the second uplink carrier by occupying the occasion and/or the period; or when a first condition is not met, determining not to send the measurement signal on the second uplink carrier by occupying the occasion and/or the period.

Abstract: A method and device for estimating the time of arrival (ToA) of a radio signal are proposed. The radio signal comprises M subsignals carried on M subcarriers, where M is an integer ≥2. The number of propagation paths and the time of arrival associated with a first path are estimated. The technique can improve ToA estimation accuracy, especially in a multipath fading channel, and reduce the need for channel information.
