Problems solved by technology

[0014] To sum up, for the TDD system, the above-mentioned prior art only ensures that the DRX cycle start values ​​of different users are evenly distributed on the subframes, and it is obviously still unable to effectively achieve the balance and resource utilization of the downlink scheduling of the base station. Balance, so it may still cause some users to be delayed in scheduling, while some downlink resources are not fully utilized

Embodiment 1

[0075] Embodiment 1: Determine the start position of the DRX cycle according to information such as the number of downlink subframes and the configuration of time slot transition points.

[0076] For TDD system frames, generally, the number of downlink subframes and uplink-downlink conversion points contained in different half-frames (or different frames) are the same, so in this embodiment, the system frames and downlink subframes can be Divide intervals for reference to achieve load balancing of downlink resources. In this embodiment, the step 601 specifically includes:

[0077] Step 611 , configure the DRX cycle of the DRX user, divide the DRX cycle into multiple intervals in units of system frames, and evenly allocate the DRX users to each interval.

[0078] Here, it is assumed that the DRX cycle includes N system frames, and each system frame includes 10 subframes. Divide the starting point of the DRX cycle into N consecutive intervals, each interval contains 10 integer...

Embodiment 2

[0089] In the second embodiment, the starting point of the DRX cycle is determined according to the dynamic load of the downlink subframe. The specific implementation method includes the following steps:

[0090] Step a1, dynamically counting the load situation of each downlink subframe. Specifically, a statistical cycle may be set, and the load situation of each downlink subframe is counted in each statistical cycle, and the statistical cycle is the maximum value allowed to be configured in the DRX cycle. The statistical load situation of the downlink subframe may be the number of users waiting to be scheduled on each downlink subframe.

[0091] Step a2, according to the statistics of the load situation of each downlink subframe and the load balancing principle, evenly configure the DRX cycle starting point of the DRX user on each downlink subframe. Here, if a new DRX user joins, select the downlink subframe with the smallest load in the next statistical period as the DRX c...

Abstract

The invention discloses a method and base station equipment for dispatching downlink communication resources. The base station equipment comprises a DRX period configuring module, a notice module and a resource allocation module. The method which is executed by the base station equipment comprises the following concrete steps: using the DRX period configuring module to configure DRX periods of DRX users and configure starting points of the DRX periods of the DRX users on downlink subframes in balance; using the notice module to notice the DRX period and the starting point of the DRX period of each DRX user to a corresponding DRX user to carry out DRX monitoring; and using the resource allocation module to dispatch corresponding downlink communication resources in balance according to the allocated starting point of the DRX period of each DRX user. The method and the base station equipment for dispatching downlink communication resources can be used for improving the balance of the downlink dispatching of the base station and the balance of the utilization ratio of resources in the DRX working mode, and can be used for reducing the defect that part of users are dispatched in delay, but part of downlink resources are not utilized fully.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method for scheduling downlink communication resources and base station equipment. Background technique [0002] Currently, in mobile communication systems based on shared channels, such as LTE mobile communication systems using 3GPP Long Term Evolution (LTE) project technology, the transmission of uplink and downlink data is generally controlled by a base station scheduler. When the scheduler determines to schedule a certain user, it will notify the user terminal (UE) on which communication resource to send or receive data through the control channel. The UE monitors the control channel, and when it detects that the control channel contains the scheduling information of the UE, completes the sending (uplink) or reception (downlink) of data according to the instruction of the scheduling information. In the activated state, since the UE is not sure when the base statio...
