其中，载波频率与服务小区的子载波间隔的对应关系为预设的对应关系。例如，当载波频率小于等于3GHz时，所述子载波间隔等于15kHz；或当载波频率大于3GHz小于等于6GHz时，所述子载波间隔等于30kHz。The correspondence between the carrier frequency and the sub-carrier spacing of the serving cell is a preset correspondence. For example, when the carrier frequency is less than or equal to 3 GHz, the sub-carrier spacing is equal to 15 kHz; or when the carrier frequency is greater than 3 GHz and less than or equal to 6 GHz, the sub-carrier spacing is equal to 30 kHz.
或，基站确定服务小区的子载波间隔，可以包括：Or, the base station determines the subcarrier spacing of the serving cell, which may include:

根据所述服务小区对应的子载波间隔集合确定所述服务小区的子载波间隔。The subcarrier spacing of the serving cell is determined according to the set of subcarrier spacing corresponding to the serving cell.
进一步可选地，所述频率集合与子载波间隔集合的对应关系可以如步骤301所述，此处不再赘述。Further optionally, the corresponding relationship between the frequency set and the subcarrier spacing set may be as described in step 301, which will not be described again here.
可选的，所述服务小区的子载波间隔属于第一子载波间隔集合，所述第一子载波间隔集合包括第一子载波间隔Δf1和第二子载波间隔Δf2，所述第一子载波间隔和所述第二子载波间隔都为15kHz的倍数或都为17.5kHz的倍数，且所述第一子载波间隔小于所述第二子载波间隔；可选地，所述第二子载波间隔是所述第一子载波间隔的2倍。Optionally, the subcarrier spacing of the serving cell belongs to a first subcarrier spacing set, which includes a first subcarrier spacing Δf 1 and a second subcarrier spacing Δf2 , and the first subcarrier spacing set includes a first subcarrier spacing Δf1 and a second subcarrier spacing Δf 2 . The carrier spacing and the second subcarrier spacing are both multiples of 15kHz or both are multiples of 17.5kHz, and the first subcarrier spacing is smaller than the second subcarrier spacing; optionally, the second subcarrier spacing The spacing is 2 times the first subcarrier spacing.
基站确定服务小区第一带宽部分的子载波间隔和确定所述服务小区第二带宽部分的子载波间隔，所述第一带宽部分的子载波间隔为所述第一子载波间隔，所述第二带宽部分的子载波间隔为所述第二子载波间隔。其中，第一带宽部分占用的频率资源和第二带宽部分占用的频率资源不同。该服务小区在不同带宽部分部署了不同的子载波间隔，能够利用更匹配的子载波间隔同时为不同的特征的用户服务，从而提高系统性能。例如对于时延扩展大的用户设备，可将其调度在第一子载波间隔对应的带宽部分，对于高速用户设备，可将其调度在第二子载波间隔对应的带宽部分。具体，例如对于频率小于等于6GHz的情况，其对应的子载波间隔集合包括15kHz和30kHz，30kHz可用于满足高达500km/h的高速场景，15kHz可用于时延扩展高达约5us的场景。The base station determines the subcarrier spacing of the first bandwidth part of the serving cell and determines the subcarrier spacing of the second bandwidth part of the serving cell. The subcarrier spacing of the first bandwidth part is the first subcarrier spacing, and the second subcarrier spacing of the serving cell is determined by the base station. The subcarrier spacing of the bandwidth portion is the second subcarrier spacing. The frequency resources occupied by the first bandwidth part are different from the frequency resources occupied by the second bandwidth part. The serving cell deploys different subcarrier intervals in different bandwidth parts, and can use more matching subcarrier intervals to serve users with different characteristics at the same time, thereby improving system performance. For example, user equipment with large delay spread can be scheduled in the bandwidth part corresponding to the first subcarrier interval, and high-speed user equipment can be scheduled in the bandwidth part corresponding to the second subcarrier interval. Specifically, for example, for frequencies less than or equal to 6GHz, the corresponding subcarrier spacing sets include 15kHz and 30kHz. 30kHz can be used to meet high-speed scenarios up to 500km/h, and 15kHz can be used for scenarios with delay extensions up to about 5us.
