TRANSFER REQUEST OF PLANNING, supports a large Doppler shift

摘要

1. A method comprising the steps of: perform block the expansion of the sequence of symbols by spreading codes, resulting in a partial orthogonality, and! transmitting one or more scheduling requests block-subjected to the expansion, with said partial orthogonality. ! 2. A method according to claim 1, intended for use in providing support to a subscriber unit moving at high speed, for reducing intercode interference caused by Doppler effect. ! 3. The method of claim 1, wherein for said expansion of said sequence of characters using a sequence of constant amplitude zero autocorrelation cyclic shift, which is specific to a particular subscriber unit. ! 4. The method of claim 1, wherein said partial orthogonality is implemented using an even number of spreading factors for said block extension. ! 5. The method of claim 1, wherein said partial orthogonality is implemented by dividing each time interval block into only two orthogonal sequences. ! 6. The method of claim 5, wherein said two orthogonal sequences comprise a first sequence of three symbols followed by a second sequence of four symbols. ! 7. The method of claim 6, wherein said first sequence is a sequence of constant amplitude zero autocorrelation (CAZAC-sequence), and said second sequence is Hadamard sequence. ! 8. The method of claim 6, wherein both sequences: n
