Problems solved by technology

[0012] Using the above scheduling method to improve the edge scheduling probability can improve the edge rate to a certain extent, but when the channel conditions of the edge users are very poor (edge ​​users before handover, or edge users seriously interfered by adjacent cells), even if they are scheduled , it is also difficult to ensure high-speed and correct data transmission
[0013] To sum up, the above three methods can improve cell edge coverage to a certain extent, but at the cost of sacrificing the throughput of the entire cell or poor communication quality

Embodiment 1

[0057] The necessary steps in this embodiment are: preferentially assign frequency points or time slots to edge user equipment; and schedule user equipment accessing frequency points or time slots.

[0058] In order to ensure that some frequency points or time slots are preferentially accessed to edge user equipment, a method of configuring the priority of each frequency point or time slot to access edge user equipment can be used. Then, the frequency points or time slots allocated to edge user equipment are prioritized. It refers to the frequency points or time slots with high priority.

[0059] Alternatively, by configuring a priority list of frequency points or time slots, after determining that the user equipment is at the edge or center of the cell, set the edge user equipment and the central user equipment to select the frequency points or time slots in the list in reverse order; then, The frequency point or time slot allocated preferentially to the edge user equipment r...

specific Embodiment 2

[0096] On the basis of Embodiment 1, this embodiment adds the consideration of the interference of adjacent cells, and in the setting of frequency points in the SDCA priority list, frequency points different from adjacent cells are preferentially accessed to edge users.

[0097] In order to effectively reduce the interference in the system and improve the throughput of the entire system, the RNC selects different frequency points for adjacent cells as much as possible to preferentially access edge users. In a multi-frequency point system, the main frequency points of adjacent cells are often different, so edge users are given priority to access the main frequency point of this cell. see Figure 4 , is a schematic diagram of multi-frequency point resource allocation referring to the interference of adjacent cells, in which cell 1 reserves the primary frequency f1 for user access at the edge (the area between the solid line and the dotted line), and f2 and f3 are the center (the...

specific Embodiment 3

[0100] For the multi-frequency point system, on the basis of the first or second embodiment, this embodiment adds the judgment of the UE type, and implements different resource allocation and scheduling strategies for different types of UEs.

[0101] According to the differences in UE capabilities, UEs can be divided into three types: Type A: Single-frequency UE developed in accordance with the 3GPP TD-SCDMA release 4 standard, which only supports sending and receiving information on the main frequency point; Type B: only supports one frequency point Send and receive information on the Internet, and support multiple frequency point systems at the same time; Type C: can support multiple frequency points to send and receive information at the same time.

[0102] When configuring resources for UEs of type A, it is mainly considered that the number of users connected to the main frequency point does not reach the upper limit N f1 (f1 is the main frequency point of the multi-freque...

Abstract

The invention discloses a wireless resource management method, including steps of: allocating frequency point and time slot to marginal customer device in preference; scheduling user device on the access frequency point and time slot. The invention configures one or more marginal customer device with resource access preference. Because difference of resource selection sequence between marginal customer and central customer, there is no interference, resource waste problem caused by adoption of resource reservation is avoided. The invention ensures that marginal customer get access to resource, with consideration of system throughput. The invention also provides a wireless network controller and a base station device.

Description

technical field [0001] The present invention relates to the technical field of radio resource management, in particular to a radio resource management method, a radio network controller (Radio Network Controller, RNC) and a base station (Node B). Background technique [0002] The goal of Radio Resource Management (RRM) is to provide service quality assurance for wireless user terminals (User Equipment, UE) in the network under the condition of limited bandwidth. The basic starting point is that the network traffic distribution is uneven 1. When the channel characteristics fluctuate due to channel fading and interference, flexibly allocate and dynamically adjust the available resources of the wireless transmission part and the network, maximize the utilization of the wireless spectrum, prevent network congestion and keep the signaling load as small as possible. The research content of radio resource management mainly includes: power control, channel allocation, scheduling, ha...
