Embodiment Construction
[0024] In order to solve the problem that the adjustment scheme of the frame division multiplexing mode of the accompanying channel in the prior art has poor flexibility and cannot meet the actual needs, the embodiment of the present invention provides a frame division multiplexing mode of the accompanying channel Adjust the plan. This solution uses the code resource utilization rate of the HSDPA carrier in a specific transmission direction and the transmission rate of the user carried by the HSDPA carrier in this direction as the basis for adjusting the frame division multiplexing mode of the accompanying channel for transmission in this direction, greatly improving It improves the flexibility of adjusting the frame division multiplexing mode of the accompanying channel. Moreover, the solution can also be adjusted separately for users with different transmission rates.
[0025] The embodiments of the present invention will be described below in conjunction with the accompany...

The invention discloses a method and device for adjusting the frame division multiplexing mode of the accompanying channel, which is used to solve the poor flexibility of the adjustment scheme of the frame division multiplexing mode of the accompanying channel in the prior art, which cannot meet the actual requirements. The question of demand. The method includes: determining the code resource utilization rate of a high-speed downlink packet access HSDPA carrier in a specific transmission direction, and the transmission rate of a user carried by the HSDPA carrier in the specific transmission direction; according to the determined code resource Utilization rate and described transmission rate, from the user that described HSDPA carrier bears the weight of, determine the user that needs to adjust the frame division multiplexing mode of accompanying channel; And the frame division multiplexing mode of the accompanying channel for transmission according to the specific transmission direction.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for adjusting the frame division multiplexing mode of accompanying channels. Background technique [0002] Time Division Synchronous Code Division Multiple Access (TD-SCDMA, Time Division Synchronous CDMA) system adopts shared Time Division Duplex (TDD, Time Division Duplex) mode, which can dynamically adjust the ratio of uplink and downlink time slots, so as to better support asymmetric services . However, due to the rapid increase of data services due to the gradual popularization of smart phones, the asymmetry of uplink and downlink traffic is still increasingly prominent. In addition, because the TD-SCDMA system itself must have some characteristics suitable for transmitting data services, such as high data volume, high Therefore, in the development process of the third generation mobile communication technology, an important enhancement technology...
