Method and apparatus for mapping of absolute power grant values in wireless communications
A method and apparatus for adjusting power grants in wireless communications. Multiple power grant tables are stored and one or more tables are designated during communication.
1. A method, comprising:
receiving a signal indicating enhanced absolute grant value channel table selection information;
selecting, based on the signal, a table comprising absolute grant value mapping information from a plurality of tables, wherein the table comprising absolute grant value mapping information is selected based on modulation type; and
determining an absolute grant value based on the selected table.
2. The method of claim 1 , wherein the signal is received from a higher layer.
3. The method of claim 1 , wherein each of the plurality of tables comprises a plurality of indices and corresponding absolute grant values.
4. The method of claim 1 , wherein the plurality of the tables are preconfigured in a wireless transmit/receive unit (WTRU).
5. The method of claim 1 , wherein the plurality of the tables are stored in a wireless transmit/receive unit (WTRU).
6. A wireless transmit/receive unit (WTRU) comprising:
a receiver configured for receiving a signal indicating enhanced absolute grant value channel table selection information; and
a processor configured to:
select, based on the signal, a table comprising absolute grant value mapping information from a plurality of tables, wherein the processor is configured to select the table based on modulation type; and
determine an absolute grant value based on the selected table.
7. The WTRU of claim 6 , wherein the signal is received from a higher layer.
8. The WTRU of claim 6 , wherein each of the plurality of tables comprises a plurality of indices and corresponding absolute grant values.
9. The WTRU of claim 6 , wherein the plurality of the tables are preconfigured in the WTRU.
10. The WTRU of claim 6 , wherein the plurality of the tables are stored in the WTRU.
11. The method of claim 1 , wherein the modulation type is 16-symbol quadrature amplitude modulation (16QAM) or binary phase-shift keying (BPSK).
12. The method of claim 1 , wherein the signal is received in a Radio Access Network (RAN) through Radio Resource Control (RRC) signaling.
13. The method of claim 1 , wherein the absolute grant value is characterized by a square of a ratio of enhanced dedicated channel (E-DCH) dedicated physical data channel (E-DPDCH) amplitude to E-DCH dedicated physical control channel (E-DPCCH) amplitude.
14. The WTRU of claim 6 , wherein the modulation type is 16-symbol quadrature amplitude modulation (16QAM) or binary phase-shift keying (BPSK).
15. The WTRU of claim 6 , wherein the receiver is configured for receiving the signal in a Radio Access Network (RAN) through Radio Resource Control (RRC) signaling.
16. The WTRU of claim 6 , wherein the absolute grant value is characterized by a square of a ratio of enhanced dedicated channel (E-DCH) dedicated physical data channel (E-DPDCH) amplitude to E-DCH dedicated physical control channel (E-DPCCH) amplitude.
