example 1
[0087] like Figure 5 As shown, when an LTE-A UE adopts a carrier configuration of 1 DL component carrier and 2 UL component carriers, a schematic diagram of the division of PHICH channel subsets; there are 4 groups of PHICH channels in the figure, and these 4 groups of PHICH channels are divided into Two PHICH channel subsets, PHICH channel subset 1 and PHICH channel subset 2, are completely disjoint between the two PHICH channel subsets. The PHICH channel of each PHICH channel subset corresponds to the ACK / NACK response of the uplink data transmission block of an uplink carrier. For the uplink carrier, within the scope of the PHICH channel included in its corresponding subset, use the extended n-DMRS The value of the value and the minimum label index of the resource block occupied by the uplink data transmission block are determined according to the LTE, or the above method 1, or method 2, or method 3, or the PHICH channel calculation method described in the third embodiment...
example 2
[0089] Each uplink carrier corresponds to a PHICH channel subset, and the PHICH channel index in the PHICH subset resource is obtained by mapping the even-numbered PRB of the uplink carrier. Specifically, the following formula can be used to illustrate:
[0090] n PHICH group = ( ( I PRB _ RA lowest _ index + ( I PRB _ RA lowest _ index mod 2 ) ) ...
example 3
[0100] When a downlink carrier provides PHICH channels for multiple uplink carriers, for the paired uplink carriers associated with the downlink carrier, its corresponding PHICH channel subset includes all PHICH channels on the downlink carrier;
[0101] For an unpaired uplink carrier, the PHICH channel subset determined for all uplink data transmission blocks in the unpaired uplink carrier includes all PHICH channels on the downlink carrier, or, for the unpaired uplink carrier The PHICH channel subset determined by all uplink data transmission blocks includes part of the PHICH channels on the downlink carrier. For example, divide all PHICH channels into multiple PHICH channel subsets, the number of PHICH channel subsets is equal to the number of unpaired carriers, each unpaired uplink carrier corresponds to a subset, and each subset completely disjoint.
[0102] Regardless of whether it is a paired uplink carrier or a non-paired uplink carrier, within the PHICH channel range...
