Abstract:
1. A method for mapping data slots to an interlace for one or more communication symbols comprising: mapping a pilot channel data slot alternately to first and second interlaces from a plurality of interlaces for each communication symbol; and variably mapping one or more other data slots to respective interlaces from the plurality where the mapping is varied for each communication symbol and wherein said variably mapping is performed according to the relationship: where N=I−1 is the number of interlaces used for data scheduling, I being a total number of the plurality of interlaces; i∈{0,1, . . . ,I−1} is the interlace index to which a particular slot s at a particular communication symbol t maps excluding the interlace used to map the pilot channel data slot; t=0, 1, . . . ,T−1 is a communication symbol index in a frame of communication symbols, T being the total number of communication symbols in a frame; s=1,2,. . . , S−1 is the slot index, S being the total number of slots; R is a number of shifts per communication symbol; and ′ is a reduced-set bit-reversal operator which is configured to exclude the interlace used to map the pilot channel data slot from the bit-reversal operation.
