Problems solved by technology

However, the use of dual-carrier HSUPA requires more network resources such as demodulation, scheduling, transmission, and air interface load than single-carrier HSUPA, so that the number of ordinary users supported by the network is reduced.

Embodiment 1

[0047] Through research, it is found that when the user terminal UE does not need to send data (that is, when there is no traffic demand), or the demand is small, activating the secondary carrier of the UE does not contribute to the throughput. When the remaining transmit power of the user terminal is insufficient (that is, when the power demand is too large), the DPCCH transmit power of the secondary carrier will not only affect the service available power of the primary carrier, but also increase the interference of the uplink secondary carrier frequency; therefore, for the uplink For a user terminal whose secondary carrier has been activated, it is more reasonable to deactivate its uplink secondary carrier if the demand for data transmission decreases or the remaining transmit power decreases.

[0048] In addition, when the load of the uplink secondary carrier cell associated with the user terminal is high, the gain brought by the activation of the uplink secondary carrier t...

Embodiment 2

[0073] This embodiment provides an apparatus for controlling the state of an uplink secondary carrier. The apparatus for controlling the state of an uplink secondary carrier may be integrated into a base station for implementation. Please refer to figure 2 shown, including: an information acquisition module and a state setting module;

[0074] The information acquisition module is used to acquire the demand status of the user terminal and the load status of the uplink secondary carrier cell associated with the user terminal;

[0075]The state setting module is used to set the activation state of the uplink auxiliary carrier of the user terminal according to the demand state of the user terminal and the load state of the uplink auxiliary carrier cell.

[0076] The uplink auxiliary carrier state control device can ensure that the user terminal activates the uplink auxiliary carrier when it is necessary and has little impact on system performance, and deactivates the uplink auxi...

Embodiment 3

[0088] This embodiment provides a base station, please refer to Image 6 As shown, it includes a memory and a processor; the memory is used to store at least one program module, and the processor is used to call the at least one program module to execute the steps in the method for controlling the state of the uplink auxiliary carrier in the above-mentioned embodiment.

[0089] In order to better understand the present invention, the following takes the base station as the execution subject and takes several specific application scenarios as examples to further illustrate the present invention.

[0090] See Figure 7 As shown, the process of uplink secondary carrier state setting and resource allocation includes:

[0091] Step 701: the base station determines whether the user terminal is activated or deactivated when the current uplink secondary carrier is activated, and sets a deactivation determination period or an activation determination period based on the determination ...

Abstract

The invention discloses an uplink auxiliary carrier state control method, an uplink auxiliary carrier state control device and a base station. During uplink auxiliary carrier state control, the demand state of a user terminal and the load state of an uplink auxiliary carrier cell associated with the user terminal are acquired, and the activation state of the uplink auxiliary carrier of the user terminal is set dynamically according to the obtained demand state of the user terminal and the obtained load state of the uplink auxiliary carrier cell, namely, the uplink auxiliary carrier is set to an activated state to obtain higher uplink transmission rate when that there is a need to activate the uplink auxiliary carrier currently is judged dynamically according to the demand state of the user terminal and the load state of the uplink auxiliary carrier cell, and the uplink auxiliary carrier is adjusted to a deactivated state to reduce the consumption of network dynamic resources when that there is no need to activate the uplink auxiliary carrier currently is judged dynamically according to the demand state of the user terminal and the load state of the uplink auxiliary carrier cell.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and base station for controlling the state of an uplink auxiliary carrier. Background technique [0002] As an upgrade technology of the UMTS standard, 3GPPR8 version introduces dual-carrier high-speed download DC-HSDPA, which greatly improves the downlink transmission rate and makes the uplink and downlink transmission rates unbalanced. The 3GPPR9 version introduces the dual-carrier high-speed uplink access DC-HSUPA technology, which uses two adjacent carriers in the same uplink frequency band to increase the uplink transmission rate. [0003] HSUPA scheduling is implemented in the base station NodeB. DC-HSUPA uses two carriers, the main carrier and the auxiliary carrier. The main carrier is always active for the user terminal UE as a normal state, and the auxiliary carrier can be activated as needed. However, at present, in order to obtain a better uplink tra...
