Embodiment

[0030] CLAIMS 1. A wireless transmit / receive unit (WTRU) configured to receive power grant assignments.

[0031] 2. The WTRU of embodiment 1 wherein the WTRU includes a power grant table.

[0032] 3. The WTRU of embodiment 1 or 2 wherein the power grant is dependent on modulation type.

[0033] 4. The WTRU as in any one of embodiments 1-3 wherein the modulation type is a quadrature amplitude modulation type.

[0034] 5. The WTRU as in any one of embodiments 1-4 wherein the first modulation type is 16QAM and the second modulation type is BPSK.

[0035] 6. The WTRU as in any one of embodiments 1-5 wherein the power grant table includes absolute grant values ​​and indices.

[0036] 7. The WTRU as in any one of the preceding embodiments wherein the WTRU further includes an index offset value.

[0037] 8. The WTRU as in any preceding embodiment, wherein the WTRU is configured to apply the index offset value to the power grant table.

[0038] 9. The WTRU as in any preceding embodi...

Abstract

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.

Description

technical field [0001] The present invention relates to wireless communications. Background technique [0002] In wireless communications, a set of permissible carrier amplitudes, power levels, or ratios of power levels may be assigned or "authorized" to a transmitter. These values ​​can be dynamic - authorizations can change over time as communication conditions change. [0003] High Speed ​​Packet Access (HSPA) is a set of mobile telephony protocols that extend and improve the performance of existing mobile telephony protocols. The evolution of HSPA to support higher system throughput and performance has led to the introduction of 16QAM modulation in the uplink. One item needed to support Higher Order Modulation (HOM) is Enhanced Pilot. [0004] Many options have been disclosed to provide enhanced pilots, including increasing the power of the Dedicated Physical Control Channel (DPCCH), increasing the power of the Enhanced Dedicated Physical Control Channel (E-DPCCH), an...
