Abstract
Systems, methods, apparatuses, and computer program products for handling limited or unavailable uplink (UL). One method may include receiving, from a user equipment, an indication that uplink transmission is limited or unavailable.
Claims14
An apparatus, comprising:
- at least one processor;
- and
- at least one memory comprising computer program code,
- the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to:
- receive, from a user equipment, an indication that uplink transmission is limited or unavailable due to maximum permissible exposure requirement, wherein when receiving the indication, the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to receive a user equipment capability information or one or more other information elements from the user equipment,
- determine whether the user equipment is able to report when there is a problem with uplink transmission based on the user equipment capability information or one or more other information elements;
- when it is determined that the user equipment is able to report when there is a problem with
- uplink transmission, configure the user equipment to report when there is a problem with the uplink transmission;
- and
- when receiving the indication, receive a report from the user equipment indicating that there is a problem with the uplink transmission being unavailable or limited,
- wherein, when the uplink transmission is still working but limited, when receiving the report, the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to receive an indication including a combined layer 2 uplink control information, UCI, and radio resource control, RRC, layer measurement results, wherein the layer 2 UCI is used to prevent releasing the user equipment connection with a radio link failure procedure in case no more acknowledgements are received from the user equipment.
8 more elements
A method, comprising:
- transmitting an indication to a network that uplink transmission is limited or unavailable due to maximum permissible exposure requirement, wherein
- the transmitting of the indication comprises:
- transmitting to the network user equipment capability information or one or more other information elements;
- receiving a configuration to report when there is a problem with the uplink transmission;
- detecting that there is a problem with the uplink transmission;
- and
- wherein the transmitting the indication comprises transmitting a report to the network
- indicating that there is a problem with the uplink transmission being unavailable or limited,
- wherein, when the uplink transmission is still working but limited, the transmitting of the report comprises transmitting an indication including a combined layer 2 uplink control information and radio resource control layer measurement results.
6 more elements
An apparatus, comprising:
- at least one processor;
- and
- at least one memory comprising computer program code,
- the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to:
- transmit an indication to a network that uplink transmission is limited or unavailable due to maximum permissible exposure requirement, wherein when transmitting the indication, the at least one memory and computer program code are further configured, with the at least one processor, to cause the apparatus at least to transmit to the network user equipment capability information or one or more other information elements,
- receive a configuration to report when there is a problem with the uplink transmission;
- detect that there is a problem with the uplink transmission;
- and
- when transmitting the indication, transmit a report to the network indicating that there is a problem with the uplink transmission being unavailable or limited,
- wherein, when the uplink transmission is still working but limited, when transmitting the report, the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to transmit an indication including a combined layer 2 uplink control information and radio resource control layer measurement results.
