Fig. 9 B illustrates the design of multiplexing structure 910, and it had both supported FSS also to support FDS, supports FSS at whole subbands.In this exemplary design, system bandwidth is divided into N
SB=6 subbands (being numbered 0 to 5), and definition M=6 time-interleaved (being numbered 0 to 5).In the exemplary design shown in Fig. 9 B, in time-interleaved 0, subband 0,1 and 2 is used for FSS; In time-interleaved 1, subband 3,4 and 5 is used for FSS; In time-interleaved 2, subband 0 and 3 is used for FSS; In time-interleaved 3, subband 1 and 4 is used for FSS; In time-interleaved 4, subband 2 and 5 is used for FSS; In time-interleaved 5, there is not subband to be used for FSS.

Usually, multiplexing structure can comprise the subband (N of arbitrary number
SB) with time-interleaved (M) of arbitrary number.The subband of arbitrary number can be used for FSS in each is time-interleaved.The subband of identical or different number can be used for FSS in M is time-interleaved.For each was time-interleaved, the subband that is used for FSS can be adjacency or non-adjacent.
In each was time-interleaved, the subband that is used for the subband of FSS and is used for FDS can be sent to the user in every way.In a kind of design, can for time-interleaved 0 subband of selecting for FSS and FDS, be defined in the subband that interweaves each remaining time for FSS and FDS based on the subband that in time-interleaved 0, is used for FSS and FDS.In a kind of design, the subband bit-masks can be for time-interleaved 0 and for N
SBEach subband in the individual subband has a bit.Can be set to 0 for the bit of each subband and be used for FDS with the expression subband, or be set to 1 and be used for FSS with the expression subband.Can time-based interweave 0 subband bit-masks of the subband bit-masks that interweave with each remaining time defines.In a kind of design, the subband bit-masks that interweave with each remaining time is the cyclic shift version of time-interleaved 0 subband bit-masks.For the time-interleaved exemplary design of the M=6 shown in Fig. 9 A, each time-interleaved subband bit-masks is as follows:
Time-interleaved 0 subband bit-masks=1,1,0,0,0,0},
Time-interleaved 1 subband bit-masks=0,0,1,1,0,0},
Time-interleaved 2 subband bit-masks=0,0,0,0,1,1},
Time-interleaved 3 subband bit-masks=1,1,0,0,0,0},
Time-interleaved 4 subband bit-masks=0,0,1,1,0,0},
Time-interleaved 5 subband bit-masks={ 0,0,0,0,1,1}.
Time-interleaved subband bit-masks also can define based on certain other mapping.The same sub-band bit-masks also can be time-interleaved for all.In either case, by using the predetermined mapping of M M time-interleaved subband bit-masks, can send single subband bit-masks so as to transmit M time-interleaved each time-interleaved in for the subband of FSS and FDS.In the another kind design, the subband that is used for FSS and FDS during each is time-interleaved can be selected and transmit independently, for example, divides other subband bit-masks to each time-interleaved use.
System can support mixed automatic retransfer (HARQ), and it is also referred to as steadily increase redundancy, follows the tracks of merging (that is, Chase merges) etc.Utilize HARQ, transmitter sends transmitted in packets, and is correctly decoded by receiver in this grouping, or has sent the maximum retransmit number, or runs into before certain other the termination condition, sends one or more re-transmissions always.HARQ can improve the reliability of transfer of data.
Can define M HARQ and interweave, wherein M can be any integer value.Each HARQ interweaves and can comprise the interval M time period of a time period (do not count in minute be used in expense time).For some examples, can define three or six HARQ and interweave (shown in Fig. 9 A), perhaps can define six HARQ interweave (shown in Fig. 9 B).Also can define less or more a plurality of HARQ interweaves.Each HARQ interweave can be corresponding one different time-interleaved.
The HARQ process refers to all transmission and re-transmission (if any) of a grouping.As long as resource can use, the HARQ process just begins, and this process after first transmission or one or more subsequently re-transmissions stop later on.The HARQ process has the variable duration, and this depends on the decoded result of receiver.Each HARQ process can be in a HARQ middle transmission that interweaves.Can in interweaving, the HARQ with subband that the user wants be FSS user resource allocation piece.
Usually, the time-interleaved time period (for example, in Fig. 9 A or 9B) can equal, is shorter than or is longer than the time interval (for example, at Fig. 5 to shown in Fig. 8) of frequency hopping.If a time period is longer than a time interval, frequency hopping can occur in each time period so.In a kind of design, the time interval is across a symbol period, and time period is across two time slots of 12 or 14 symbol periods.In this design, frequency hopping can one by one symbol period ground generation within each time period of two time slots.In the another kind design, a time period equals a time interval, both equals a symbol period, a time slot, subframe etc.In this design, for FSS, in each was time-interleaved, frequency hopping one by one time period ground occured.For FDS, frequency hopping can time-interleavedly be carried out respectively for each, or time-interleavedly jointly carries out across all.
Figure 10 illustrates the design of multiplexing structure 1000, utilizes among the time-interleaved m Resource Block frequency hopping across a subband to support FSS.In this exemplary design, time-interleaved m comprises time period m, m+M etc., corresponding time slot of each time period, corresponding symbol period of each time interval.

RB=8 Physical Resource Block 0 to 7, and define eight virtual resource blocks 0 to 7.Based on pseudorandom saltus step pattern, in each symbol period of time-interleaved m, each virtual resource blocks is mapped in the Physical Resource Block 0 to 7.In the symbol period 0 of time period m virtual resource blocks 0 is mapped to Physical Resource Block 0, is mapped to Physical Resource Block 5 in symbol period 1, be mapped to Physical Resource Block 2 in symbol period 2, the rest may be inferred.Virtual resource blocks 0 to 7 to the mapping of Physical Resource Block 0 to 7 as shown in figure 10 in each symbol period of time-interleaved m.Figure 10 illustrates pseudorandom saltus step pattern, also can use other saltus step patterns.
Usually, different saltus step patterns can be used for the frequency hopping of FDS and FSS.FDS can use identical saltus step pattern with FSS, and perhaps FDS can use different saltus step patterns from FSS.The saltus step pattern can be for example other pattern of cyclic shift pattern or certain of fixedly saltus step pattern.The saltus step pattern also can generate based on known function or maker, and it can receive any parameter as input or seed.In a kind of design, the saltus step pattern is used for each residential quarter or the sector of system.Adjacent cell or sector can use different saltus step patterns so that the interference randomization between cell/section.
In a kind of design, the saltus step pattern of each residential quarter or sector is static in time, and repeats within the predetermined duration (for example, the subframe of predetermined number).For example, based on fixing saltus step pattern, for example, the cyclic shift pattern can be carried out frequency hopping to Q Resource Block collection across 12 or 14 symbol periods in each subframe.At the first symbol period of each subframe, virtual resource blocks 0 to Q-1 can be mapped to respectively Physical Resource Block 0 to Q-1.At each residue symbol period of this subframe, each virtual resource blocks can be mapped to different Physical Resource Block.
In the another kind design, the saltus step pattern of each residential quarter or sector is time dependent.The saltus step pattern can define based on known function, for example, is exclusively used in the function of the pseudorandom scrambler of this residential quarter or sector.For example, based on fixing saltus step pattern, for example, the cyclic shift pattern can be carried out frequency hopping to Q Resource Block collection across 12 or 14 symbol periods in each subframe.Yet the initial mapping of first symbol period can be determined based on four bits of scrambler.For example, if 4 bit scrambler values are q, for first symbol period of subframe, virtual resource blocks 0 can be mapped to Physical Resource Block q so, and virtual resource blocks 1 can be mapped to Physical Resource Block (q+1) mod Q, and the rest may be inferred.4 bit scrambler values can change between subframe, become frequency hopping during with realization.
