Problems solved by technology

[0017] Disadvantage 1: In violation of the 3GPP standard, the standard stipulates that the terminal cannot activate / deactivate the Scell ​​locally, and can only activate / deactivate the Scell ​​under the instruction of the network device on the system side
[0018] Disadvantage 2: When the terminal reports CQI=0, the network equipment on the system side may not be able to be scheduled, resulting in network compatibility issues
Although the 3GPP standard stipulates that the activation / deactivation of the Scell ​​is determined by the system side, it does not clearly indicate when the network device should activate / deactivate the Scell
If the terminal reports CQI=0, the network device side may not be able to deactivate the corresponding Scell. If the terminal side independently deactivates the corresponding Scell, a network compatibility problem occurs.
[0019] Disadvantage 3: Deactivating the Scell ​​locally on the terminal will cause downlink packet loss, and there may be a situation where the corresponding Scell ​​cannot be deactivated on the network device side. Facing the shortcomings of activation, deactivation, and activation cycles, the purpose of thermal mitigation cannot be achieved

Embodiment 1

[0110] Step1: When the UE (User equipment) detects an overheating problem, the UE judges the cause of the problem.

[0111] How the UE detects the overheating problem and how to determine the cause of the overheating problem is determined by the user equipment.

[0112] Step 2: When the UE judges that the problem can be solved by reducing the number of activated Scells, the RRC layer of the UE triggers a message reporting process. The function of the message reporting process is to notify the base station that an overheating problem has occurred or that the overheating problem has been resolved. The overheating problem indication message reported to the base station includes auxiliary information. The content of the auxiliary information includes:

[0113] Option 1: The number of Scells in the active state that the UE can support, or the number of downlink Scells that can be supported in the active state and / or the number of uplink Scells in the active state that can be supp...

Embodiment 2

[0135] Step 1: When the UE detects an overheating problem, the UE judges the cause of the problem.

[0136] How the UE detects the overheating problem and how to determine the cause of the overheating problem is determined by the user equipment.

[0137] Step 2: When the UE judges that the problem can be solved by reducing the number of activated Scells, the RRC layer of the UE triggers a message reporting process. The function of the message reporting process is to notify the base station of its updated wireless access capability. The message reported to the base station includes various band combinations currently supported by the UE and various downlink BandwidthClasses and / or various uplink BandwidthClasses that can be supported on each band in each band combination.

[0138] Under what conditions the UE triggers the message reporting process (for example, how high the temperature of the UE reaches) is determined by the implementation of the user equipment.

[0147] Step 1: When the UE detects an overheating problem, the UE judges the cause of the problem.

[0148] How the UE detects the overheating problem and how to determine the cause of the overheating problem is determined by the user equipment.

[0149] Step 2: When the UE judges that the problem can be solved by reducing the number of activated Scells, the RRC layer of the UE triggers a message reporting process. The function of the message reporting process is to notify the base station that its wireless access capability has been updated, and trigger the base station to reacquire its updated wireless access capability through the existing UE capability acquisition process. The message reported to the base station includes an indication of UE radio access capability update.

[0150] Under what conditions the UE triggers the message reporting process (for example, how high the temperature of the UE reaches) is determined by the implementation of the user equipment.

Abstract

The present application discloses a method, related apparatus and system for adjusting radio resource configuration. The method may include: the user equipment detects an overheating problem, and the user equipment sends a first message to the network equipment for notifying the network equipment that the user equipment has an overheating problem. The user equipment receives a second message sent by the network device, where the second message is used to instruct the UE to reconfigure the maximum number of MIMO layers. By implementing the above solution, the terminal can solve the problem of overheating under the condition that the network is not connected and complies with the standard.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method, a related device and a system for adjusting wireless resource configuration. Background technique [0002] Currently, a terminal implements high-speed data transmission through carrier aggregation (Carrier Aggregation, CA) and multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO). Carrier aggregation aggregates multiple component carriers (Component Carrier, CC) together to increase transmission bandwidth and improve data transmission rate. MIMO uses multiple radio frequency receive chains and multiple radio frequency transmit chains to increase the capacity of the transmission channel, thereby increasing the data transmission rate. [0003] With the evolution of 3GPP standards, from 2CC+2MIMO, 3CC+4MIMO to 4CC+4MIMO, the corresponding carrier aggregation capability and MIMO capability of the terminal are continuously improved, a...
