Method and apparatus for reducing peak power in code multiplexed downlink control channels |
摘要 |
A method and apparatus that reduces the likelihood of having a high peak power in any one bit position of code multiplexed downlink control channel symbols is described herein. An exemplary method includes selecting a different bit-level spreading sequence for each mobile terminal from a set of orthogonal bit-level spreading sequences, where code values in any one bit position are not the same for all of the bit-level spreading sequences in the set. When a code multiplexing system uses the selected bit-level spreading sequences from the sequence set to code multiplex the downlink control channel symbols, the resulting combined signal has a lower likelihood of having a high peak power. |
