Systems and methods for power control in wireless systems
Methods and systems are described for determining a total available transmission power at a time interval for a wireless/transmit unit (WTRU) and determining a power level associated with a transmission based on the total available transmission power and a spectrum operation mode (SOM). A SOM may be associated with one or more transmission characteristics. Transmission power may be allocated to the transmission according to the power level determination.
1. A method implemented in a wireless transmit/receive unit (WTRU), the method comprising:
receiving, from a network, a configuration indicating a first amount of transmission power to be reserved for a first subset of transmissions and a second amount of the transmission power to be reserved for a second subset of the transmissions, wherein the first subset of the transmissions is characterized by a first spectrum operation mode (SOM), the second subset of the transmissions is characterized by a second SOM, and the first SOM differs from the second SOM in at least one transmission aspect;
determining that one or more of a first transmission using the first SOM or a second transmission using the second SOM is to be performed;
allocating power to the one or more of the first transmission or the second transmission in accordance with the configuration; and
performing the one or more of the first transmission or the second transmission using at least the allocated power.
2. The method of claim 1 , wherein the at least one transmission aspect relates to a time interval associated with performing the one or more of the first transmission or the second transmission.
3. The method of claim 1 , wherein the at least one transmission aspect relates to a transmission numerology.
4. The method of claim 1 , wherein the at least one transmission aspect relates to at least one of a quality of service (QoS) level, a hybrid automatic repeat request (HARQ) processing aspect, or a waveform type.
5. The method of claim 1 , wherein the first amount of transmission power to be reserved is equal to a first portion of a total amount of available transmission power for the WTRU, and wherein the second amount of transmission power to be reserved is equal to a second portion of the total amount of available transmission power for the WTRU.
6. The method of claim 5 , further comprising determining a remaining amount of transmission power based on the total amount of available transmission power and allocating at least a portion of the remaining amount of transmission power to another transmission.
7. The method of claim 1 , wherein the power is allocated to the one or more of the first transmission or the second transmission further based on a power control mode (PCM) associated the first SOM or the second SOM.
8. The method of claim 7 , wherein the configuration further indicates the PCM associated the first SOM or the second SOM.
9. The method of claim 1 , further comprising receiving, from the network, an indication of one or more characteristics of the first SOM or the second SOM.
10. A wireless transmit/receive unit (WTRU) comprising: a processor configured to:
receive, from a network, a configuration indicating a first amount of transmission power to be reserved for a first subset of transmissions and a second amount of the transmission power to be reserved for a second subset of the transmissions, wherein the first subset of the transmissions is characterized by a first spectrum operation mode (SOM), the second subset of the transmissions is characterized by a second SOM, and the first SOM differs from the second SOM in at least one transmission aspect;
determine that one or more of a first transmission using the first SOM or a second transmission using the second SOM is to be performed;
allocate power to the one or more of the first transmission or the second transmission in accordance with the configuration; and
perform the one or more of the first transmission or the second transmission using at least the allocated power.
11. The WTRU of claim 10 , wherein the at least one transmission aspect relates to a time interval associated with performing the one or more of the first transmission or the second transmission.
12. The WTRU of claim 10 , wherein the at least one transmission aspect relates to a transmission numerology.
13. The WTRU of claim 10 , wherein the at least one transmission aspect relates to at least one of a quality of service (QoS) level, a hybrid automatic repeat request (HARQ) processing aspect, or a waveform type.
14. The WTRU of claim 10 , wherein the first amount of transmission power to be reserved is equal to a first portion of a total amount of available transmission power for the WTRU, and wherein the second amount of transmission power to be reserved is equal to a second portion of the total amount of available transmission power for the WTRU.
15. The WTRU of claim 14 , wherein the processor is further configured to determine a remaining amount of transmission power based on the total amount of available transmission power and allocate at least a portion of the remaining amount of transmission power to another transmission.
16. The WTRU of claim 10 , wherein the power is allocated to the one or more of the first transmission or the second transmission further based on a power control mode (PCM) associated the first SOM or the second SOM.
17. The WTRU of claim 16 , wherein the configuration further indicates the PCM associated the first SOM or the second SOM.
18. The WTRU of claim 10 , wherein the processor is further configured to receive, from the network, an indication of one or more characteristics of the first SOM or the second SOM.
