Abstract
A user equipment can send a notification to a network node indicating that the user equipment is entering a battery saving mode of operation. Reduced physical layer procedures can be implemented based on reduced capabilities indicated by the user equipment. Reduced physical layer procedures can also be implemented based on the network node's reconfiguration of parameters to facilitate the activation of the reduced physical layer procedures. The user equipment can also send to the network node recommendations of reduced physical layer procedures.
Claims20
A user equipment, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- detecting a decrease in a level of charge of a battery of the user equipment that transitions a threshold level of charge;
- in response to the decrease in the level of charge, facilitating transmitting a first notification to a network device that the user equipment is entering a battery saving mode of operation;
- receiving an acknowledgement of the first notification from the network device;
- determining a reduced group of physical layer operating capabilities smaller than a current group of physical layer operating capabilities, the reduced group of physical layer operating capabilities being related to:
- transmissions on a physical uplink channel from the user equipment to the network device and on a physical downlink channel from the network device to the user equipment,
- a channel state information feedback process that determines parameters related to a protocol for the transmissions, and
- radio resource management measurements that monitor signals for a quality of the transmissions;
- facilitating transmitting a second notification informing the network device of the reduced group of physical layer operating capabilities, wherein the second notification comprises configuration data representative of a configuration of the reduced group of physical layer operating capabilities;
- and
- facilitating operating the user equipment according to the reduced group of physical layer operating capabilities, wherein the operating comprises receiving the transmissions from the network device, wherein the transmissions are in response to the second notification and reflect compliance by the network device with the reduced group of physical layer operating capabilities determined by the user equipment.
A network device, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- receiving, from a user equipment, a notification that the user equipment is entering a battery saving mode of operation, wherein the notification comprises configuration data associated with a configuration of reduced physical layer communications procedures;
- in response to receiving the notification, facilitating transmitting to the user equipment an acknowledgement of the notification;
- determining, without regard to power saving implementation capabilities of the user equipment, the reduced physical layer communications procedures comprising fewer procedures than physical layer communications procedures when the user equipment is not in the battery saving mode of operation, the reduced physical layer communications procedures comprising:
- an uplink and downlink procedure applicable to first transmissions via a physical uplink channel from the user equipment to the network device and second transmissions via a physical downlink channel from the network device to the user equipment,
- a channel state information feedback procedure for determination of first parameters related to a protocol for the first transmissions and the second transmissions, and
- a radio resource management procedure applicable to radio resource management measurements used to monitor signals that relate to a quality of the first transmissions and the second transmissions;
- and
- reconfiguring second parameters to facilitate an activation of the reduced physical layer communications procedures by the network device and at the user equipment.
A method, comprising:
- detecting, by a user equipment comprising a processor, a drop in a level of charge of a battery of the user equipment below a threshold;
- in response to the drop in the level of charge, facilitating transmitting, by the user equipment, a notification to a network node device that the user equipment is entering a battery power preservation mode of operation that is to consume less battery power than a standard power mode of operation, and
- receiving, by the user equipment, an acknowledgement from the network node device of the notification;
- facilitating transmitting, by the user equipment to the network node device, a signal comprising a recommendation, which is deniable by the network node device, of first physical layer communications procedures fewer in number than second physical layer procedures that are applicable to the standard power mode of operation, wherein the signal further comprises configuration data representative of the first physical layer communications procedures, the recommendation of the first physical layer communications procedures relating to:
- transmissions via a physical uplink channel from the user equipment to the network node device and via a physical downlink channel from the network node device to the user equipment,
- analysis of channel state information feedback to determine parameters related to a protocol for the transmissions, and
- radio resource management measurements to monitor signals that relate to a quality of the transmissions.
