[0065] Such as Figure 5 As shown, as the second embodiment of the present invention, after the distributed unit sends the radio link status report to the central unit, the central unit sets the trigger threshold according to the radio link status report. However, the trigger time does not need to be set in the embodiment provided by the present invention. Therefore, once the distributed unit detects that the state of the wireless link has met the trigger threshold, it sends a trigger indication to the central unit. The central unit allocates uplink reference signal transmission resources according to the trigger indication, and sends the resources to the distributed units for users to transmit uplink reference signals.

[0066] The embodiments provided by the present invention are especially suitable for situations where communication quality is highly required.

Abstract

The invention discloses an adaptive uplink reference signal transmission method and corresponding functional units. The method includes the following steps: adjusting the triggering threshold of the uplink reference signal; when the triggering threshold is met, allocating uplink reference signal resources for the user to send the uplink reference signal. In the present invention, by setting trigger conditions, the user can send the uplink reference signal in time when the wireless link state is degraded; when the wireless link state is relatively stable, the transmission of the uplink reference signal is reduced, thereby improving user communication quality and reducing signaling overhead.

Description

technical field [0001] The invention relates to an adaptive uplink reference signal transmission method, and also relates to a central unit and a distributed unit for adaptive uplink reference signal transmission, belonging to the technical field of wireless communication. Background technique [0002] Such as figure 1 As shown, in the next-generation wireless access network, the traditional base station will evolve into an architecture in which the central unit (referred to as CU) and the distributed unit (referred to as DU) are separated, and each CU can control multiple DUs. DU works in the high frequency band to meet the user's data rate requirements, and uses beamforming technology to transmit directional beams to overcome high attenuation in the high frequency band. The number of beams is very large, which will bring great challenges to user measurement configuration and mobility management. [0003] In the LTE technology, a downlink-based mobility management soluti...
