Systems and methods for signaling for AI use by mobile stations in wireless networks
A method in a user equipment (UE), involves configuring an artificial intelligence (AI) module in a UE to perform at least one task for wireless communications and then performing the task using the configured AI module. The AI module may be on a SIM card inserted into the UE, or part of an internal software implementation. Configuring the AI module can be based on default parameters stored in the UE, or based on signalling received from a network.
1. A method in a user equipment (UE), the method comprising:
configuring an artificial intelligence (AI) module in a UE to perform at least one task for wireless communications;
performing the at least one task using the configured AI module;
receiving signalling from the network informing the UE of the at least one task the UE is to perform using the configured AI module;
wherein the at least one task comprises one or more of:
channel estimation;
control signal reception and/or data signal reception;
control signal and/or data signal demodulation;
downlink and/or uplink spatial domain filtering;
radio link monitoring;
mobility management and reporting;
beam management and reporting;
channel state information feedback;
interference cancellation;
equalization;
the method further comprising receiving signalling from the network with parameters for use in configuring the AI module, the parameters configuring one or more of:
input type and/or output type;
Size and format;
Layer configuration;
Feature map size;
Format;
Number of neurons;
Coefficients of link between neurons of neighboring layers;
Activation functions;
the method further comprising:
activating the AI module upon insertion of a subscriber identity module (SIM) card in the UE;
wherein configuring the AI module in the UE to perform at least one task for wireless communications is based on parameters stored in the SIM card.
2. The method of claim 1 further comprising:
receiving a UE capability enquiry message from a network;
responding to the UE capability enquiry with a UE capability response message indicating the UE's AI capability;
receiving signalling to configure the UE to perform a given wireless communications task.
3. The method of claim 1 further comprising:
receiving a UE capability enquiry message from a network;
responding to the UE capability enquiry with a UE capability response message indicating the UE's AI capability;
receiving signalling to configure the UE to perform a given wireless communications task;
receiving signalling containing parameters for the UE to configure its AI module.
4. A user equipment (UE) comprising:
A processor and memory;
at least one antenna;
an artificial intelligence (AI) module;
wherein the AI module is configured to perform at least one task for wireless communications and to receive signalling from the network informing the UE of the at least one task it is to perform using the configured AI module;
wherein the at least one task comprises one or more of:
channel estimation;
control and/or data signal reception;
control and/or data signal demodulation;
downlink and/or uplink spatial domain filtering;
radio link monitoring;
mobility management and reporting;
beam management and reporting;
channel state information feedback;
interference cancellation;
equalization;
wherein the UE is configured to receive signalling from the network with parameters to configure the AI module for use in configuring the AI module by receiving one or more of:
input type and/or output type;
Size and format;
Layer configuration;
Feature map size;
Format;
Number of neurons;
Coefficients of link between neurons of neighboring layers;
Activation functions;
the UE further comprising:
a subscriber identity module (SIM) card slot;
wherein the UE is configured to:
activate the AI module upon insertion of a subscriber identity module (SIM) card in the SIM card slot;
wherein the AI module is configured to perform at least one task for wireless communications based on parameters stored in the SIM card.
5. The UE of claim 4 further configured to:
receive a UE capability enquiry message from a network;
respond to the UE capability enquiry with a UE capability response message indicating the UE's AI capability;
receive signalling to configure the UE to perform a given wireless communications task.
6. The UE of claim 4 further configured to:
receive a UE capability enquiry message from a network;
respond to the UE capability enquiry with a UE capability response message indicating the UE's AI capability;
receive signalling to configure the UE to perform a given wireless communications task;
receiving signalling containing parameters for the UE to configure its AI module.
