Abstract

The invention provides a method and a device for allocating resources for a physical hybrid automatic repeat request indicator channel. The method comprises the following steps of: acquiring a physical resource block number offset corresponding to a minimum physical resource block number according to a group number, a sequence number, the number of a plurality of component carriers and the number of first component carriers, and acquiring a first group number and a first orthogonal sequence number according to the group number, the sequence number, the physical resource block number offset, the minimum physical resource block number and a first demodulation reference signal cycle offset. Because the physical resource block number offset is related to the number of the first component carriers, the physical resource block number offset corresponds to different component carriers, even if the minimum physical resource block number is the same, corresponding physical resource block number offsets are different, and a group number and an orthogonal sequence number of the corresponding resource allocation result can be different. In the mode, when total resources to be allocated are enough, the resource allocation conflict of different component carriers due to the same minimum physical resource block number can be avoided.

Description

Be physical mixed automatic repeat requests indicating channel method of allocating resources and device

Technical field

The application relates to the resource allocation in the wireless communication system, relates in particular to be physical mixed automatic repeat requests indicating channel method of allocating resources and device.

Background technology

LTE-Advanced (Long Term Evolution system-Advanced) mobile communication system will be supported the higher spectral bandwidth than LTE Rel-8 (Release 8), these frequency spectrums may be dispersed in a lot of scattered passages, these frequency spectrums need be gathered use.Carrier aggregation technology can address this problem, and promptly system can go up at a plurality of component carriers (component carrier) simultaneously according to the practical capacity of oneself and send or receive data.About the application of carrier aggregation technology, reached following common recognition, support symmetry and asymmetrical carrier aggregation; And, from user's angle, a corresponding transmission block (TB, transport block) and a HARQ (Hybrid Automatic Repeat request mixes automatic repeat requests) entity on each component carrier when spatial reuse (no).

According to above-mentioned common recognition, in carrier aggregation system, Physical Uplink Shared Channel (the PUSCH that on a plurality of upstream components carrier waves, exists as the user, when Physical Uplink SharedCHannel) transmitting, downlink component carrier need transmit a plurality of ACK/NACK (positive acknowledgement/Negative Acknowledgement) signal.Under the carrier aggregation scene of symmetry, downlink component carrier and upstream components carrier wave can keep one-to-one relationship, as shown in Figure 1.Can directly expand the automatic repeat requests indicating channel of physical mixed (PHICH, the Physical HARQindicator CHannel) design of Rel-8 this moment, the ack/nack signal of the corresponding upstream components carrier wave of transmission on each downlink component carrier.Yet, under asymmetric carrier aggregation scene, shown in Fig. 2 a and Fig. 2 b, downlink component carrier and upstream components carrier wave no longer have one-to-one relationship, can not directly use the design of Rel-8, especially at the upstream components carrier number during greater than the downlink component carrier number, a downlink component carrier must be supported the ack/nack signal transmission of a plurality of upstream components carrier waves.In addition, the ack/nack signal of a plurality of upstream components carrier waves of transmission can also satisfy the requirement of different bandwidth class user on single downlink component carrier, can effectively support the interference coordination in the heterogeneous network (Heterogeneous Network).

In the design of LTE Rel-8, transmit by PHICH behind the ACK/NACK bit of the user uplink PUSCH correspondence process BPSK repeated encoding.A plurality of PHICH are mapped on the identical physics running time-frequency resource, constitute a PHICH group, make a distinction by multiple quadrature Walsh sequence extension between Nei the PHICH on the same group.The resource that PHICH occupies is by two parameter (n _PHICH ^Group, n _PHICH ^Seq) expression, n _PHICH ^GroupExpression PHICH group #, n _PHICH ^SeqOrthogonal sequence numbering in the expression group.For fdd mode, PHICH group number N _PHICH ^GroupFixing in all subframes, by downlink bandwidth N _RB ^DLN with the high level outfit _gDecision.
