Abstract
Methods, apparatuses, and systems directed to adaptive uplink power control in a wireless network are provided. Among the apparatuses is a wireless transmit/receive unit that may include any of a receiver, a transmitter, and a processor coupled to the receiver and the transmitter. The processor may identify, from a plurality of transmissions, a first group of transmissions for transmission during a first transmission opportunity of a first uplink. The processor may determine a first power level for the first group of transmissions based, at least in part, on a characteristic of the first transmission opportunity and a characteristic of a second transmission opportunity of a second uplink, wherein the second transmission opportunity may be usable for transmission of a second group of the plurality of transmissions. The first and second characteristics may define respective time resources, where at least some of the first and second time resources overlap. The transmitter may transmit the first group of transmissions at least at the first power level.

Claim
1. A method, implemented in a wireless transmit/receive unit (WTRU), directed to power allocation, the method comprising:
identifying, from a plurality of transmissions, a first group of transmissions for transmission by the WTRU during a first transmission opportunity on a first uplink; determining a first power level for the first group of transmissions based, at least in part, on one or more first characteristics of the first transmission opportunity and one or more second characteristics of a second transmission opportunity on a second uplink, wherein the second transmission opportunity is usable by the WTRU for transmission of a second group of the plurality of transmissions; and transmitting the first group of transmissions at least at the first power level during a first transmission opportunity.
2. The method of claim 1, wherein the first and second characteristics define first and second time resources of the first and second transmission opportunities, respectfully, and wherein at least some of the first and second time resources overlap.
3. The method of claim 2, wherein the first and second time resources define respective start times and durations.
4. The method of claim 1, wherein the one or more first characteristics and the one or more second characteristics comprise respective channel access methods, and wherein at least the first channel access method defines a listen-before-talk (LBT) mechanism.
5. The method of claim 1, wherein the one or more first characteristics and the one or more second characteristics comprise respective channel access methods, wherein the first channel access method defines a listen-before-talk (LBT) mechanism, and wherein the second channel access method does not define a LBT mechanism.
6. The method of claim 1, wherein the first uplink comprises one or more physical resources of unlicensed spectrum, and wherein the second uplink comprises one or more physical resources of licensed spectrum.
7. The method of claim 6, further comprising:
determining a second power level for the second group of transmission based, at least in part, on excluding a portion of available power reserved for the first transmission opportunity; or determining a likelihood of transmitting any of the first group of transmissions during the first transmission opportunity based on scheduling information; and on condition that the likelihood is zero or satisfies (e.g., is less than or equal to) a configured threshold, reserving a portion of available power for the first transmission opportunity; and determining a second power level for the second group of transmission based, at least in part, on excluding the portion of available power reserved for the first transmission opportunity.
8. The method of claim 7, further comprising:
determining whether the second power level exceeds a second guaranteed power level associated with the second group of transmissions; and on condition that the second power level exceeds the second guaranteed power level, adjusting any of the first guaranteed power level, a second guaranteed power level associated with the second group of transmissions, and a remaining power level, wherein the remaining power level corresponds to a difference between a maximum power and the first and second guaranteed power level combined, if any.
9. The method of claim 8, further comprising:
determining whether the first power level exceeds the first guaranteed power level associated with the first group of transmissions; and on condition that the first power level exceeds the first guaranteed power level, adjusting any of the first guaranteed power level, the second guaranteed power, and the remaining power level, if any.
10. The method of claim 6, further comprising:
determining whether the first power level exceeds a first guaranteed power level associated with the first group of transmissions; and on condition that the first power level exceeds the first guaranteed power level, adjusting any of the first guaranteed power level, a second guaranteed power level associated with the second group of transmissions, and a remaining power level, wherein the remaining power level corresponds to a difference between a maximum power and the first and second guaranteed power level combined, if any.
11. The method of claim 1, wherein the one or more first characteristics and the one or more second characteristics comprise respective channel access methods, and wherein at least the second channel access method defines a listen-before-talk (LBT) mechanism.
12. The method of claim 1, wherein the one or more first characteristics and the one or more second characteristics comprise respective channel access methods, wherein the first channel access method does not define a listen-before-talk (LBT) mechanism, and wherein the second channel access method defines a LBT mechanism.
13. The method of claim 11, wherein the first uplink comprises one or more physical resources of licensed spectrum, and wherein the second uplink comprises one or more physical resources of unlicensed spectrum.
14. The method of claim 12, wherein the first uplink comprises one or more physical resources of licensed spectrum, and wherein the second uplink comprises one or more physical resources of unlicensed spectrum.
15. The method of claim 13, wherein determining a first power level comprises:
excluding a portion of available power reserved for the second transmission opportunity.
16. The method of claim 14, wherein determining a first power level comprises:
excluding a portion of available power reserved for the second transmission opportunity.
17. The method of claim 13, further comprising:
determining a likelihood of transmitting any of the second group of transmissions during the second transmission opportunity based on scheduling information; and on condition that the likelihood is zero or satisfies (e.g., is less than or equal to) a configured threshold,
reserving a portion of available power for the second transmission opportunity,
wherein determining the first power level comprises excluding the portion of available power reserved for the second transmission opportunity.
18. The method of claim 14, further comprising:
determining a likelihood of transmitting any of the second group of transmissions during the second transmission opportunity based on scheduling information; and on condition that the likelihood is zero or satisfies (e.g., is less than or equal to) a configured threshold, reserving a portion of available power for the second transmission opportunity, wherein determining the first power level comprises excluding the portion of available power reserved for the second transmission opportunity.
19. The method of claim 1, wherein identifying the first group of transmissions comprises identifying transmissions based on the one or more first characteristics and the one or more second characteristics.
20. A wireless transmit/receive unit (WTRU) comprising circuitry, including a transmitter, receiver, processor and memory, configured to:
identify, from a plurality of transmissions, a first group of transmissions for transmission by the WTRU during a first transmission opportunity on a first uplink; determine a first power level for the first group of transmissions based, at least in part, on one or more first characteristics of the first transmission opportunity and one or more second characteristics of a second transmission opportunity on a second uplink, wherein the second transmission opportunity is usable by the WTRU for transmission of a second group of the plurality of transmissions; and transmit the first group of transmissions at least at the first power level during a first transmission opportunity.
