Dispatching method in the CA of a kind of enhancing and device

Technical field

The present invention relates to the scheme of CA (Carrier Aggregation, carrier aggregation), especially Relate to the PHICH in CA based on LTE (Long Term Evolution, Long Term Evolution) system (Physical Hybrid-ARQ Indicator CHannel, physical mixed HARQ Instruction channel) resource distribution scheme.

Background technology

Traditional 3GPP (3rd Generation Partner Project, third generation affiliate Project) in LTE system R (Release, version) 10 formulated, CA as key technology it One is introduced into, and its core concept is that subscriber equipment (UE-User Equipment) can be simultaneously Over a number of carriers, CA can improve the peak rate of single UE in work.In LTE CA, UE quilt Configure a Pcell (Primary Cell, main Serving cell), one or more Scell (Secondary Cell, auxiliary serving cell).For FDD (Frequency Duplex Division, FDD) LTE, a Serving cell includes in { descending carrier, a up-link carrier } At least one descending carrier.For TDD (Time Duplex Division, time division duplex) LTE, One Serving cell includes a carrier wave.In LTE R10, support that the UE of CA is at best able to be joined Put 5 Serving cells, DCI (Downlink Control Information, a descending control Information processed) Serving cell can only be dispatched.In LTE system, it is used for indicating PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) the upper TB (Transport transmitted Block, transmission block) HARQ (the Hybrid Automatic Repeat that whether is correctly received ReQuest, hybrid automatic repeat-request) _ ACK (response) is at PHICH (Physical HARQ Indicator Channel, Physical HARQ Indicator Channel) above transmit, shared by HARQ_ACK PHICH resource is by { orthogonal sequence index in PHICH group number (Group number), PHICH group } Institute's common definition, for given TB, its PHICH resource taken is for (specifically describing reference 9.1.2 joint in TS36.213):

$n_{\mathrm{PHICH}}^{\mathrm{group}}=(I_{\mathrm{PRB}\_\mathrm{RA}}+n_{\mathrm{DMRS}})\mathrm{mod}{N}_{\mathrm{PHICH}}^{\mathrm{group}}+I_{\mathrm{PHICH}}{N}_{\mathrm{PHICH}}^{\mathrm{group}}$ Formula 1

Formula 2

Wherein,It is PHICH group number,It is orthogonal sequence index, n_DMRSGiven by with described Determine the PDCCH (Physical of up DCI format that the last time of TB association receives Downlink Control Channel, Physical Downlink Control Channel) in DMRS (Demodulation Reference Signal, demodulated reference signal) cyclic shift domain mapping Obtain,It it is spreading factor.I_{PRB_RA}It is that described given TB accounts on first time slot of PUSCH Minimum PRB index (or adding 1),It is the PHICH group number of high-level signaling configuration, I_PHICHIt it is the regulation parameter (being 0 for other scenes) that used of TDD UL/DL frame structure #0.

In LTE R13, research topic is to increase the community that CA supported and counts to most 32 (described problem is referred to as eCA in the present invention).Although maximum up-link carrier number is likely less than 32, One rational expection is, the maximum that the maximum up-link carrier number supported in eCA is supported more than CA Up-link carrier number.
