Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a distributed base station system and related devices, methods and storage media. Background technique [0002] Currently, with the increasing development of wireless communication technology, high-quality transmission of wireless communication signals becomes more and more important. [0003] Typically, in existing wireless communication systems (such as 3G, 4G, 5G mobile communication technologies, etc.), a distributed base station system is usually used to achieve indoor coverage, that is, the baseband processing unit (Baseband Unit, BBU) of the traditional macro base station and A radio frequency processing unit (Remote Radio Unit, RRU) is separated, and the two are connected by an optical fiber. Therefore, in the actual network deployment, the baseband processing unit, core network and wireless network control equipment are centrally placed in the computer room...

Problems solved by technology

For the above-mentioned new application scenarios, the existing distributed base station structure has the following problem: when two users respectively use two physical channels multiplexed at the same frequency, in the same time slot, the two physical channels are separated from each other. will interfere with

For example, in the same time slot, mobile terminals UE_A and UE_B respectively used by users A and B served by the base station receive data on the same frequency from different serving EUs or serving pRRUs, that is, user A uses the frequency domain Resource F1, user B uses the frequency domain resource F2 on this frequency. At this time, the following problems may occur: for UE_A, only the power allocated on F1 is effective power. Similarly, for UE_B, only the power allocated on F2 The power is effective power, therefore, the power on F2 is invalid for UE_A, and the power on F1 is invalid for UE_B (that is, from the perspective of the entire system, the power utilization rate has not reached the highest)

In addition, for UE_A, the power allocated to F2 will cause interference to the frequency domain resource F1 allocated to UE_B, and for UE_B, the power allocated to F1 will cause interference to the frequency domain resource F2 allocated to UE_B. The intensity of the interference It is related to the resource allocation method of F1 and F2 and the power on F1 and F2. At the same time, in order to prevent the frequency domain resources allocated to each user from interfering with the frequency domain resources allocated to other users, the power delivered by the base station cannot be increased arbitrarily. Large, thus limiting the communication coverage of the base station
