Description

Information transmission method and device Technical Field The present application relates to the field of wireless communications technologies, and in particular, to an information transmission method and apparatus. Background The New Radio (NR) introduced the concept of measurement timing configuration (SSB-based measurement timing configuration, SMTC) based on synchronization signals and physical broadcast channel blocks (SSB). SMTC may be understood as a time window configured by a base station for a terminal to measure synchronization signals and physical broadcast channel blocks (SSBs), and the terminal need only make SSB measurements within the time window and need not make SSB measurements outside the time window. The SMTC configuration is a frequency bin level configuration, and the base station configures a SMTC list for each frequency bin, and configures a maximum of 4 SMTCs, which may include a baseline SMTC and other 3 SMTCs. The other 3 SMTCs correspond to a given set of cell identities and offset parameters (offsets), respectively, using the period and duration of the baseline SMT indication. Thus, all SMTCs included in each bin can only correspond to the same period and duration, i.e., the period and duration indicated in the baseline SMTC. In the SMTC configuration manner, when a plurality of cells of a frequency point configure different SSB periods, the current SMTC configuration mechanism cannot support SSB measurement. Disclosure of Invention The application provides an information transmission method and device for improving SSB measurement efficiency. In a first aspect, there is provided an information transmission method, which may be performed by a first apparatus. The "first device" in the present application may refer to a terminal device, a component in the terminal device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can implement all or part of the functions of the terminal device, unless specifically stated otherwise. In the method, a first device receives first information indicating first list information including N SSB-based measurement timing configuration SMTC list information. The first SMTC list information includes one or more offset values, the first SMTC information list is one of N SMTC list information, and N is a positive integer. Wherein the N SMCT list information corresponds to N SSB periods. The first device performs SSB measurements based on all or part of the N SMTC list information. Wherein all or part of the N SMTC list information is determined based on the N SSB periods. Based on the above scheme, the first device can determine SMTC list information used when performing SSB measurement according to the SSB period corresponding to the SMTC list information, and even when one frequency point multiple cells configure different SSB periods, the first device can complete SSB measurement, so that measurement efficiency can be improved. In one possible implementation, the first SMTC list information further comprises a period value and a duration. For example, the SSB period corresponding to the first SMTC list information may be determined according to one period value included in the first SMTC list information. Based on the above scheme, the network side may configure the first device with a plurality of SMTC list information, where each SMTC list information may include a period value, a duration, and one or more offset values, so that the first device determines SMTC list information used when performing SSB measurement. In one possible implementation, the first information further indicates second list information, the second list information includes N baseline SMTC configuration information, the first baseline SMTC configuration information includes one or more of a period value, a duration time, and a bias value, the first baseline SMTC configuration information is one of the N baseline SMTC configuration information, and the first list information and the second list information are in one-to-one correspondence with an order of the N baseline SMTC configuration information in an order of the N SMTC list information. Illustratively, the first SMTC list information corresponds to a first baseline SMTC configuration information. The SSB period corresponding to the first SMTC list information may be determined according to a period value included in the first baseline SMTC configuration information. Based on the above scheme, the first device may determine, according to the baseline SMTC configuration information, a period value and a duration corresponding to the SMTC list information corresponding thereto, so that the first device may determine SMTC list information used when performing SSB measurement. In one possible implementation, the first device selects all or part of the N SMTC list information according to the SSB period supported by the first device, and performs SSB measurement.
