应理解，在网络设备向终端设备配置了多个BWP的情况下，网络设备可以基于终端设备的业务情况的变化使得终端设备在不同的BWP之间进行切换，然而不同配置的BWP切换所对应的切换时延是不同的。例如若终端设备当前工作的BWP为BWP1，切换的目标BWP为BWP2。如果BWP1与BWP2具有相同的中心频点，且BWP1与BWP2采用相同的子载波间隔，只是他们的带宽大小不一样，此时BWP1与BWP2之间的切换时延最短，对应地，BWP切换的能耗也相对最小；反之，如果BWP1与BWP2具有完全不同中心频点，和/或，BWP1与BWP2采用不同的子载波间隔，和/或，BWP1与BWP2带宽大小也不一样，这些情况下BWP1与BWP2之间的切换时延都较长，最长的切换时延可能高达数个毫秒(ms)。It should be understood that, in the case where the network device configures multiple BWPs to the terminal device, the network device may cause the terminal device to switch between different BWPs based on the changes in the terminal device's service conditions, however, the BWP switching of different configurations corresponds to The switching delay is different. For example, if the current working BWP of the terminal device is BWP1, the switching target BWP is BWP2. If BWP1 and BWP2 have the same center frequency point, and BWP1 and BWP2 use the same subcarrier spacing, but their bandwidths are different, then the switching delay between BWP1 and BWP2 is the shortest. Correspondingly, the BWP switching capability Consumption is also relatively minimal; on the contrary, if BWP1 and BWP2 have completely different center frequency points, and / or, BWP1 and BWP2 use different subcarrier spacing, and / or, BWP1 and BWP2 have different bandwidths. In these cases, BWP1 and BWP2 The switching delay between BWP2 is relatively long, and the longest switching delay may be as high as several milliseconds (ms).

基于上述要求，为了达到快速的BWP切换，减少切换BWP的耗能，一种方式是在向终端设备配置的4个BWP中，至少2个BWP满足具有相同中心频点，相同子载波间隔，仅带宽大小不一样的条件。但如此配置也有相应的弊端，即使得网络设备配置的最多4个BWP之间具有一定的关联性或者相互依赖性，限制基站调度的灵活性。Based on the above requirements, in order to achieve fast BWP switching and reduce the energy consumption of switching BWP, one way is to configure at least 2 BWPs with the same center frequency point and the same subcarrier interval among the 4 BWPs configured to the terminal device. Conditions with different bandwidths. However, this configuration also has corresponding disadvantages, that is, the network devices configured with a maximum of 4 BWPs have a certain correlation or interdependence, which limits the flexibility of base station scheduling.

为了解决上述问题，本申请引入子BWP(sub-BWP或son-BWP)的概念。对于网络设备向终端设备配置的至少一个BWP，额外配置所述至少一个BWP的sub-BWP或son-BWP。终端设备可以在BWP与其对应的子BWP之间迅速切换，适应不同的业务量需求，达到较好的节能效果，同时本申请方案不限制现有BWP的配置，因此不影响网络设备调度的灵活性。In order to solve the above problems, this application introduces the concept of sub-BWP (sub-BWP or son-BWP). For at least one BWP configured by the network device to the terminal device, a sub-BWP or son-BWP of the at least one BWP is additionally configured. The terminal device can quickly switch between the BWP and its corresponding sub-BWP to adapt to different business volume requirements and achieve better energy-saving effects. At the same time, the scheme of this application does not limit the configuration of the existing BWP, so it does not affect the flexibility of network device scheduling .
