Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application is the U.S. national phase of PCT Application No. PCT/CN2020/076744 filed on Feb. 26, 2020, the content of which is incorporated herein by reference in its entirety for all purposes. TECHNICAL FIELD Examples of the present disclosure relate to the technical field of communication, and in particularly relate to communication methods and devices, and storage media. BACKGROUND In a 5th Generation (5G) New Radio (NR) system, certain types of services require low latency, such as a type of Ultra Reliable and Low Latency Communication (URLLC) service. This type of service usually expects that a transmitter with data to be transmitted can obtain transmission resources as soon as possible, which reduces the latency due to the data waiting in the transmitter's buffer, so as to reduce the transmission latency of the air interface. In the 5G NR system, a User Equipment (UE) is expected to perform mobility measurement to ensure that the UE can always connect to a cell whose signal quality is within a required range. For performing the mobility measurement, the UE is expected to periodically measure a reference signal from at least one neighbor cell. In a case that a bandwidth of the UE's receiver is not sufficient to cover both service frequencies of a present cell and a to-be-measured cell, the UE can perform measurement on the to-be-measured cell at a regular interval. In this case, a base station is to configure a measurement gap for the UE. For example, a measurement gap period may be 40 ms, and the measurement gap may last 6 ms. An offset for configuring the measurement gap may be 20 ms, and then 20-25 ms, 60-65 ms and 100-105 ms (and so on), which are examples of measurement gaps that may be used in inter-frequency measurement. During the measurement gap, normal downlink service data reception and possible intra-frequency measurement between the UE and a serving cell may be interrupted. When the measurement gap ends, the UE may return to a frequency of the serving cell and continue the normal downlink service data reception and the possible intra-frequency measurement. When performing the inter-frequency measurement during the measurement gap, the UE's receiver cannot receive downlink information from the present serving cell. In a case that the serving cell is to transmit downlink URLLC service data, the UE cannot receive downlink data of the URLLC service during a time period of the measurement gap.
