The structure of above-mentioned this running time-frequency resource can be applied to the data transmission method that above-mentioned various embodiments provide In embodiment, and then while saving overhead bit, blind examination of the network equipment to every set running time-frequency resource is avoided, avoids generating Processing delay.

It should be understood that the structure of above-mentioned improved running time-frequency resource also can be applied to conventional network equipment to every The blind examination process of running time-frequency resource is covered, due to the overlapping configuration of resource, the network equipment is carrying out first set running time-frequency resource to detect it Afterwards, the testing result to first set resource can be reused when detecting to second set of running time-frequency resource.Such as in Fig. 8 and Fig. 9 There is overlapping region in a set of running time-frequency resource and second set of running time-frequency resource, two sets of running time-frequency resources, when overlapping for every set running time-frequency resource When region uses identical MCS, data demodulation result may be reused.

Be exemplified below: if UE selects the 2nd set of running time-frequency resource in Fig. 8 to send data, network side is first to first set at this time Then data demodulation on running time-frequency resource finds the UE not during decoding CRC check and is using first set resource, then net Network side is continued to second set of resource blind examination, and network side does not need re-demodulation in the data in second set of resource of demodulation at this time The data of two sets of running time-frequency resources and first set running time-frequency resource overlapping part, directly using the result to a set of resources measurement.And In existing structure such as Fig. 7, first demodulate the data of first set resource, after cannot reuse first in the data of second set of resource of demodulation The demodulation result of resource is covered, in contrast, the resource structures in Fig. 8 reuse this side of testing result of first set resource Formula reduces processing delay and complexity.Similarly, the overlapping region based on every set running time-frequency resource uses the premise of identical MCS, When the resource of overlapping region repeats to map identical data information, data decoding result may be reused.When every set time-frequency When the DMRS mapping ruler of the overlapping region of resource is identical, i.e., exist on overlapping RB each, the position the RE phase of DMRS mapping With (as be all mapped on the 1st, 3,5 RE), and when orthogonal covering codes (OCC) sequence for using is identical, the detection knot of DMRS Fruit may be reused.

In conclusion the detection knot of first set running time-frequency resource can be reused when the network equipment detects second set of running time-frequency resource Fruit, this considerably improves the network equipments cannot reuse the mode of testing result, drop in the blind examination process to more set resources Low processing delay and complexity, improve the efficiency of receiver.
