Problems solved by technology

[0009] The traditional SDMA-based shared channel resource allocation method cannot well ensure the balance of the load level of each group, so it cannot effectively guarantee the QoS of each UE, and allocates one layer of resources to all UEs. The defect that the UE in the handover area cannot guarantee its data transmission performance well

Embodiment Construction

[0053] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0054] The invention proposes a method for allocating shared channel resources based on SDMA, which is mainly applicable to indoor distributed systems. For indoor distribution systems, it can be combined with physical space attribution judgment and scheduling pairing. When the isolation between each physical space is relatively good, the mutual interference can be reduced to an acceptable range. At this time, the relationship between each physical space is equivalent to cell division, so each physical space can be scheduled separately, that is There is no need to consider the pairing of UEs belonging to different physical spaces. Obtain the physical space attributi...

Abstract

The invention provides a shared channel resource allocation method based on a space division multiplexing address (SDMA) technology, which comprises the following steps of: 102, assigning a plurality of user terminals to different independent physical spaces to acquire the independent physical space assignment information of the plurality of user terminals, and performing time-domain scheduling on the plurality of user terminals to determine a priority of the plurality of user terminals; 104, determining the user terminals subjected to the time-domain scheduling in each independent physical space according to the independent physical space assignment information, the priority and the number of shared channel resources; and 106, allocating the shared channel resources to the user terminals. Besides, the invention further provides a shared channel resource allocation system based on the SDMA technology. According to the shared channel resource allocation method based on the SDMA technology and the shared channel resource allocation system based on the SDMA technology provided by the invention, the data transmission performance of users is guaranteed effectively, and the quality of service (QoS) of the users in the system and fairness among the users can be guaranteed more effectively.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for allocating shared channel resources based on SDMA. Background technique [0002] In order to improve resource utilization and system throughput and meet the QoS (Quality of Service) requirements of various services, the LTE (Long Term Evolution, Long Term Evolution) system uses a shared channel mechanism to implement system dynamic resource allocation. The resource sharing of each user and each business within the network. At the same time, in order to make full use of space resources, the LTE system adopts SDMA (Space division multiplexing Access) technology. By utilizing the irrelevance of different user space channels, there are multiple independent fading paths, and these users are assigned the same time-frequency resources for data transmission, thereby increasing system capacity. [0003] The LTE system is a system that uses a shared channel for transmissi...
