Uplink transmissions in wireless communications
Methods and devices for offloading and/or aggregation of resources to coordinate uplink transmissions when interacting with different schedulers are disclosed herein. A method in a WTRU includes functionality for coordinating with a different scheduler for each eNB associated with the WTRU's configuration. Disclosed methods include autonomous WTRU grand selection and power scaling, and dynamic prioritization of transmission and power scaling priority.
1. A wireless transmit/receive unit (WTRU) comprising:
a processor configured to receive information which includes a grant for an uplink transmission, wherein the information is received based on a first radio network temporary identifier (RNTI) or a second RNTI;
the processor further configured to determine a parameter for the uplink transmission, wherein the processor determines the parameter from a first set of parameters on a condition that the information is received based on the first RNTI or from a second set of parameters on a condition that the information is received based on the second RNTI; and
the processor further configured to transmit the uplink transmission based on the determined parameter.
2. The WTRU of claim 1 , wherein the information comprises a downlink control information (DCI).
3. The WTRU of claim 1 , wherein the parameter comprises a modulation and coding scheme (MCS).
4. The WTRU of claim 1 , wherein the first set of parameters comprises a first MCS table, and the second set of parameters is a second MCS table.
5. The WTRU of claim 1 , wherein the uplink transmission comprises a physical uplink shared channel (PUSCH) transmission.
6. The WTRU of claim 1 , wherein the processor determines the parameter implicitly based on a search space in which the information is decoded.
7. The WTRU of claim 1 , wherein the processor determines the parameter explicitly based on the RNTI based on which the information is received.
8. A method implemented in a wireless transmit/receive unit (WTRU), the method comprising:
receiving information which includes a grant for an uplink transmission, wherein the received information is received based on a first radio network temporary identifier (RNTI) or a second RNTI;
determining a parameter for the uplink transmission from a first set of parameters on a condition that the information is received based on the first RNTI or from a second set of parameters on a condition that the information is received based on the second RNTI; and
transmitting the uplink transmission based on the determined parameter.
9. The method of claim 8 , wherein the information comprises a downlink control information (DCI).
10. The method of claim 8 , wherein the parameter comprises a modulation and coding scheme (MCS).
11. The method of claim 8 , wherein the first set of parameters comprises a first MCS table, and the second set of parameters is a second MCS table.
12. The method of claim 8 , wherein the uplink transmission comprises a physical uplink shared channel (PUSCH) transmission.
13. The method of claim 8 , wherein the parameter is determined implicitly based on a search space in which the information is decoded.
14. The method of claim 8 , wherein the parameter is determined explicitly based on the RNTI based on which the information is received.
15. A base station comprising:
a processor configured to transmit information which includes a grant for an uplink transmission, wherein the information is transmitted based on a first radio network temporary identifier (RNTI) or a second RNTI, wherein a parameter is determinable for the uplink transmission from a first set of parameters on a condition that the information is transmitted based on the first RNTI or from a second set of parameters on a condition that the information is transmitted based on the second RNTI; and
the processor is further configured to receive the uplink transmission based on the parameter.
16. The base station of claim 15 , wherein the information comprises a downlink control information (DCI).
17. The base station of claim 15 , wherein the parameter comprises a modulation and coding scheme (MCS).
18. The base station of claim 15 , wherein the first set of parameters comprises a first MCS table, and the second set of parameters is a second MCS table.
19. The base station of claim 15 , wherein the uplink transmission comprises a physical uplink shared channel (PUSCH) transmission.
20. The base station of claim 15 , wherein the parameter is determinable implicitly based on a search space in which the information is decoded, or explicitly based on the RNTI based on which the information is received.
