Problems solved by technology

[0004] In the existing centralized wireless access network, when the baseband processing unit BBU needs to transmit a packet to the user terminal device UE, the baseband processing unit BBU transmits the packet to all the remote radio heads RRH01-RRH20, thus causing the baseband The network traffic between the frequency processing unit BBU and the remote radio heads RRH01-RRH20 is occupied by a large number of packets

Embodiment Construction

[0033] The detailed features and advantages of the present disclosure are described in detail below in the embodiments, the content of which is sufficient to familiarize anyone with

[0034] Please refer to FIG. 2, which is used to illustrate an operation flow of the centralized wireless access network. When referring to Figure 2, please

[0035] Next, all the remote radio heads RRH01 to RRH20 wait to receive a pre-report from the user terminal equipment UE.

[0038] In an embodiment, when there are too many control signals of the second type of downlink packets to be transmitted, the physical downlink control

[0043] In an embodiment, the N estimated coordinates C1-CN are set in the first estimated region R1. For example, N is equal to

[0045] Because the estimated coordinates C1'~C6' are all within the communication range of the remote radio head end RRH09. Therefore, in an implementation

[0053] The following uses a simulation environment to illustrate the progress of the ...

Abstract

A centralized radio access network control method, suitable for a centralized radio access network with a plurality of remote radio heads and a baseband processing unit, said method comprising: collecting first uplink information about a first user terminal device Signal. A first estimated area is determined according to the communication range of the remote radio head receiving the first uplink signal. N estimated coordinates are set in the first estimated area, wherein N is an integer greater than 1. N moving directions are given to N estimated coordinates. Correct N estimated coordinates according to the maximum displacement and N moving directions. Selecting at least one remote radio head to transmit the third type of downlink packet to the first user terminal device according to the N revised estimated coordinates.

Description

A centralized wireless access network control method technical field [0001] The present disclosure relates to a control method for a centralized wireless access network, and in particular, to a handover-free centralized wireless access network. A control method for a wire access network. Background technique [0002] Centralized Radio Access Network (C-RAN) or Cloud A radio access network (cloud RAN) is a high-density base station connected to a large number of distributed remote radio heads (remote radio head, RRH) equipment network. C‑RAN uses virtualization technology and software-defined network architecture to Medium baseband resource technology. This technology brings significant changes to baseband card architecture and design. baseband and radio cards The connection and calculus functions also change, effectively sharing resources for load balancing and network fault tolerance transfer functions. C‑RAN Simplifies the backhaul network (back haul), but al...
