METHODS, APPARATUSES AND COMPUTER PROGRAM PRODUCTS FOR DETERMINING A RESOURCE INDEX

摘要

This disclosure provides methods for determining or calculating a default Enhanced Dedicated Channel, E-DCH, resource index, and apparatuses for performing the method. In some embodiments, a method for calculating a E-DCH resource index includes: receiving a Concurrent Transmission Time Interval, TTI, Partition Index, CTPI, and calculating (SigInd+CTPI) mod Y or calculating (SigInd mod (Y−CTPI))+CTPI, where Y is the total number of E-DCH resources configured in a cell for Enhanced Uplink in CELL_FACH state and IDLE mode, and SigInd is the signature index value of the Nth PRACH preamble signature corresponding to an access indicator, AI, that is configured available in the cell and corresponding to E-DCH transmission for Enhanced Uplink in CELL_FACH state and IDLE mode.

1. A method for determining a default Enhanced Dedicated Channel, E DCH, resource index, comprising:
storing a Concurrent Transmission Time Interval, TTI, Partition Index, CTPI; storing an ordered set of signatures, wherein each signature included in the ordered set is mapped to a default common E-DCH 2 ms TTI resource; assigning a signature index value of zero to the first signature included in said ordered set; for each other signature included in said set, assigning a signature index value to the signature wherein the assigned signature index value is one greater than the signature index value assigned to the immediately preceding signature in said set; for a given signature included in the ordered set, determining the signature index value, SigInd, assigned to the given signature; and for the given signature, determining the default E DCH resource index mapped to the given signature by calculating one of: a) (SigInd+CTPI) mod Y and b) (SigInd mod (Y−CTPI))+CTPI, where Y is the total number of E-DCH resources configured in the cell for Enhanced Uplink in CELL_FACH state and IDLE mode.
