Description

Communication method, device and storage medium Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method, an apparatus, and a storage medium. Background With the development of wireless communication systems and the application of various technologies (e.g., multi-band, multi-mode) in wireless communication systems, wireless communication systems provide higher and higher transmission rate services for terminals, and also provide possibilities for a wide variety of wireless network-based applications. In order to meet the higher transmission rate requirements, standardization bodies in the field of communications have introduced a number of enhancement techniques, including carrier aggregation (Carrier Aggregation, CA). CA technology involves band combining so that a terminal can use carriers in multiple bands at the same time, not limited to using a single carrier. In the protocol, a corresponding transmission power class and a performance index corresponding to the transmission power class may be defined for a frequency band combination, where one frequency band combination may correspond to a plurality of transmission power classes, and for each transmission power class, a corresponding index needs to be defined in a communication standard for the transmission power class to be able to be activated. Because the number of frequency bands is more and the number of frequency band combinations is more, in the protocol, the standardization work of the default power class of the frequency band combinations is preferentially carried out, the establishment work of the indexes required by the high power class of the frequency band combinations is not completed, so that the terminal is limited to the default power class, but cannot use the high power class, and the uplink transmission rate of the terminal is reduced. Disclosure of Invention The application provides a communication method, a device and a storage medium, which solve the technical problem that a terminal cannot perform high-power transmission under the condition that the high-power category of frequency band combination is undefined. In a first aspect, the present application provides a communication method, applied to a terminal, where the communication method includes, when N single-frequency bands exist in a frequency band combination and have high power transmitting capability, sending index information to a network device, where N is greater than or equal to 1, receiving frequency band indication information sent by the network device, where the frequency band indication information is determined by the network device based on the index information, and sending an uplink signal on an uplink target frequency band indicated by the frequency band indication information, where the uplink target frequency band is one or more of the N single-frequency bands. In some embodiments, the index information includes a downlink maximum sensitivity degradation MSD for each frequency band in the frequency band combination or a downlink MSD delta for each frequency band in the frequency band combination. In some embodiments, in the single-band operation mode, the index information includes N sets of downlink MSDs or N sets of downlink MSD increments, where each set of downlink MSDs includes downlink MSDs of each band, and each set of downlink MSD increments includes downlink MSD increments of each band, and the N sets of downlink MSDs or the N sets of downlink MSD increments are in one-to-one correspondence with the N single bands. In some embodiments, for a first one of the N single-bands, the set of downlink MSDs corresponding to the first single-band includes downlink MSDs for each band with high power transmission on the first single-band. In some embodiments, for a first one of the N single-bands, in a set of downlink MSD increments corresponding to the first single-band, the downlink MSD increment for each band is determined based on a downlink MSD for each band in the case of high power transmission on the first single-band and a downlink MSD for each band corresponding to a default power in a single-band mode of operation. In some embodiments, the downlink MSD increment for each frequency band is the difference between the downlink MSD for each frequency band in the case of high power transmission on the first single frequency band and the downlink MSD for each frequency band corresponding to the default power in the single frequency band mode of operation. In some embodiments, the uplink target frequency band is one or more of N single frequency bands, and the frequency band indication information indicates the terminal to perform high-power transmission on each uplink target frequency band when the number of the uplink target frequency bands is multiple. In some embodiments, the N sets of downstream MSDs or N sets of downstream MSD increments are sent to the network devic
