Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for allocating downlink control channel power.
Background
Based on the B-trunk (broadband Trunking) alliance standard, trunking services mainly include single call and group call services. The trunking single call is a point-to-point communication, the calling and called terminals all establish RRC (Radio Resource Control) connection, and the service data transmission is the same as the traditional LTE (Long Term Evolution) mode; the trunking group calling adopts a one-to-many communication mode, one talk right user talks, and a plurality of called terminals listen at the same time. Therefore, the cluster group call downlink adopts the shared channel transmission, no RRC connection exists, and a plurality of called terminals receive data from the shared channel at the same time.
The cluster group calling shared channel is characterized in that the downlink multi-terminal is shared, and the uplink has no feedback, so that the power distribution of the cluster group calling downlink control channel adopts a semi-static algorithm: the background configures the aggregation level of the Control Channel Element (CCE) and the power offset of the trunking Control Channel, initially sets different offset values according to different CCE aggregation levels, and is not adjustable for subsequent use.
The control channel power distribution method is simple and can work normally when the number of cluster users is small. However, considering the coverage of the trunking network and the randomness of terminal distribution, the degree of polymerization of the control channel CCE of the trunking call is generally high, which causes that power overload of the downlink control channel is easily generated under the condition that the CFI (canonica format indicator) is 1, or the number of users is large, or the bandwidth is small, and an RRU (Remote Radio Unit) is easily damaged when operating under the power overload for a long time. If power overload protection is started on software, air interface resources cannot be fully utilized due to insufficient scheduling times or insufficient Resource Blocks (RBs) caused by power overload.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, a flowchart of a method for controlling channel power allocation is shown, where an execution subject of the method may be a network side device, such as a base station, and the method includes the following steps:
s101, acquiring a DTX overrun report of the cluster terminal.
The cluster is a group of entities working cooperatively, is used for providing a service platform with higher expansibility and usability than a single service entity, and improves the efficiency by increasing the number of tasks executed in unit time.
The cluster terminal refers to a terminal in a cluster group calling scene.
The DTX is an operation mode in which the transmitter operates only when a voice needs to be transmitted in a call state, and different processing is performed during a call and at a call interval, so that the resource utilization rate can be improved.
In this embodiment, the cluster terminal monitors the DTX number in the monitoring window in real time, and when the monitored DTX number exceeds the cluster DTX threshold, the cluster terminal reports a DTX overrun report to the base station. The cluster DTX threshold may be configured by the operation and maintenance center, and is sent to the base station by the operation and maintenance center, and then sent to the cluster terminal by the base station.
In this embodiment, the DTX overrun report is transmitted through a random access procedure or a DCCH (Dedicated Control Channel), specifically, when an RRC (Radio resource Control ) is in an IDLE state, the DTX overrun report of the trunking terminal is reported through the random access procedure, and when the RRC is in a CONNECTED state, the DTX overrun report of the trunking terminal is reported through the DCCH Channel.
S102, adjusting the power offset of the trunking control channel according to the DTX overrun report sent by the trunking terminal.
The adjusting of the Channel power offset refers to adjusting the power of a Physical Downlink Control Channel (PDCCH), where the PDCCH carries scheduling and other Control information, including transport format, resource allocation, power Control, and the like.
In this embodiment, when sending a message through the trunking control channel, the base station performs power up of the control channel when receiving the DTX overrun report, and dynamically adjusts the power of the trunking network through feedback of the trunking terminal, thereby meeting the requirement of sending the message and reducing waste of resources.

S202, transmitting the cluster DTX threshold value and the cluster monitoring window parameter to the cluster terminal through the group calling configuration message.
In this embodiment, when the base station and the cluster terminal establish the group call, the cluster DTX threshold and the cluster monitoring window are issued to the cluster terminal through the group call configuration message. The cluster DTX threshold value and the cluster monitoring window parameter can be configured through the operation maintenance center, and are sent to the base station by the operation maintenance center, and then are sent to the cluster terminal by the base station.
S203, acquiring a DTX overrun report of the cluster terminal.
In this embodiment, when the trunking terminal accesses the group call, the group call configuration message is analyzed, the trunking DTX threshold and the trunking monitoring window are saved, the DTX number is monitored in real time through the trunking monitoring window, if the DTX number exceeds the trunking DTX threshold, the trunking terminal generates a DTX overrun report, the DTX overrun report is transmitted to the base station through a random access process or a DCCH, and the base station receives the DTX overrun report.
S204, adjusting the cluster control channel power bias according to the DTX overrun report sent by the cluster terminal.
The adjusting of the channel power offset refers to adjusting the PDCCH power, where the PDCCH carries scheduling and other control information, including transport format, resource allocation, power control, and the like.
In this embodiment, when the message is sent through the trunking control channel, and the base station receives the DTX overrun report, the power of the control channel is raised, and the power of the trunking control channel is increased.
In summary, in this embodiment, a DTX overrun report generated when the DTX number exceeds a cluster DTX threshold is acquired, and according to the acquisition condition of the DTX overrun report, the power of the downlink control channel of the cluster group call is dynamically adjusted, so as to ensure that the cluster terminal reliably demodulates the control channel information, and meanwhile, it is ensured that downlink air interface resources are fully utilized, and system capacity is improved.

The parameters can be transmitted to the base station by the operation center for storage.
In this embodiment, when the base station receives the DTX overrun report, the base station raises the control channel power offset according to the cluster control channel power raising step size, thereby avoiding the downlink control channel power overload and protecting the RRU device.
It should be noted that, after the control channel power bias is raised, the total power of the control channel does not exceed the RRU protection power, so that damage caused by long-time operation of the RRU under overload can be prevented.
S305, after the power offset is lifted, information is sent through the cluster control channel, and if the times of not receiving the DTX overrun report reported by the cluster terminal reaches the continuous no-DTX threshold value, the power offset is reduced according to the pre-configured power reduction step length of the cluster control channel.
In this embodiment, when the base station continuously sends a message to the trunking terminal through the trunking control channel for multiple times, the base station does not receive the DTX overrun report, and reaches the continuous no-DTX threshold, and then actively reduces the step length according to the trunking control channel power to reduce the control channel power bias, so that the control channel power can be reduced under the condition that the trunking group call can normally work, and the resource waste is reduced. To sum up, in this embodiment, the control channel power offset is raised when the DTX overrun report is received, and the control channel power offset is reduced when the number of times that the DTX overrun report is not received continuously reaches the continuous no-DTX threshold value, which can ensure that the cluster group call can work normally, ensure that air interface resources are fully utilized, improve system capacity, and protect RRU devices.
