Abstract
A device may receive a signal from a wireless station; and determine a network-permitted Time Division Duplex (TDD) uplink duty cycle based on the signal. If the determined network-permitted TDD uplink duty cycle is greater than a maximum allowable TDD uplink duty cycle for the device, when the device performs TDD uplink transmission after receiving a scheduling grant from the wireless station, the device may decrease the TDD uplink duty cycle of the device or may decrease a time-average transmission power of the device.
Claims20
A device comprising:
- a memory to store instructions and information indicating a duty cycle threshold of the device or a power limit of the device;
- and
- a processor to execute the instructions to:
- receive a signal from a wireless station, wherein the signal indicates permitted Time Division Duplex (TDD) uplink symbol positions and other TDD symbol positions in a specified period;
- determine a network-permitted TDD uplink duty cycle based on the received signal, wherein the network-permitted TDD uplink duty cycle is equal to a ratio of a number of the permitted TDD uplink symbol positions to a total number of symbol positions in the specified period;
- determine whether the network-permitted TDD uplink duty cycle is greater than a maximum allowable TDD uplink duty cycle determined based on the stored information;
- and
- when the network-permitted TDD uplink duty cycle is determined to be greater than the maximum allowable TDD uplink duty cycle, when the device performs TDD uplink transmission after receiving an uplink scheduling grant from the wireless station, decrease a TDD uplink duty cycle of the device or decrease a time-average transmission power of the device.
A method comprising:
- receiving, at a device that includes information indicating a duty cycle threshold of the device or a power limit of the device, a signal from a wireless station, wherein the signal indicates permitted Time Division Duplex (TDD) uplink symbol positions and other TDD symbol positions in a specified period;
- determining a network-permitted TDD uplink duty cycle based on the signal, wherein the network-permitted TDD uplink duty cycle is equal to a ratio of a number of the permitted TDD uplink symbol positions to a total number of symbol positions in the specified period;
- determining whether the network-permitted TDD uplink duty cycle is greater than a maximum allowable TDD uplink duty cycle determined based on the stored information;
- and
- when the network-permitted TDD uplink duty cycle is determined to be greater than the maximum allowable TDD uplink duty cycle, when the device performs TDD uplink transmission after receiving an uplink scheduling grant from the wireless station, decreasing a TDD uplink duty cycle of the device or decreasing a time-average transmission power of the device.
The method of 11, further comprising:
- sending capability information pertaining to the device to the wireless station.
A non-transitory computer-readable medium, comprising computer-executable instructions, when executed by a processor in a device including information indicating a duty cycle threshold of the device or a power limit of the device, which cause the processor to:
- receive a signal from a wireless station, wherein the signal indicates permitted Time Division Duplex (TDD) uplink symbol positions and other TDD symbol positions in a specified period;
- determine a network-permitted TDD uplink duty cycle based on the signal, wherein the network-permitted TDD uplink duty cycle is equal to a ratio of a number of the permitted TDD uplink symbol positions to a total number of symbol positions in the specified period;
- determine whether the network-permitted TDD uplink duty cycle is greater than a maximum allowable TDD uplink duty cycle determined based on the stored information;
- and
- when the network-permitted TDD uplink duty cycle is determined to be greater than the maximum allowable TDD uplink duty cycle, when the device performs TDD uplink transmission after receiving an uplink scheduling grant from the wireless station, decrease the TDD uplink duty cycle of the device or decrease a time-average transmission power of the device.
