Description
Technical field
The present invention relates to the communications field, and especially, relate to the method for sending information and the device that are used for sending physical mixing retransmission indicating chanel (Physical Hybrid ARQ Indicator Channel, PHICH is referred to as PHICH) group in the broadband wireless system.
Background technology
In quadrature product division multiplexing (OFDM) system, by correctly reply/wrong responses (Acknowledged/Non-acknowledged, ACK/NACK) control signal represents to transmit correct/error, need to judge whether to retransmit with this.
At present, stipulate in the LTE system that the ACK/NACK message that upstream data is relevant is transmitted in physical mixing retransmission indicating chanel (Physical Hybrid ARQ Indicator Channel, PHICH).The corresponding PHICH of ACK/NACK message.
An ACK/NACK message is corresponding to 1 bit raw information, then, 1 bit raw information is carried out 3 codings of repetition, carry out again k times of spread spectrum, become the m bit, m=3 * k is through binary phase shift keying (BPSK) modulation, be mapped on the I road or Q road of 3 resource subcarriers that group comprises, each resource group comprises 4 subcarriers.When Cyclic Prefix is the regular circulation prefix, k=4; When Cyclic Prefix is extended cyclic prefix, k=2, and the PHICH resource is divided timing, distributes take 3 resource groups as unit, corresponding 3 the resource groups of PHICH.So, when Cyclic Prefix is the regular circulation prefix, a PHICH group can be by spreading code and 8 PHICH of I/Q road position multiplex, corresponding 12 subcarriers of PHICH group, be mapped on 3 resource groups, when Cyclic Prefix is extended cyclic prefix, a PHICH group can be by spreading code and 4 PHICH of I/Q road position multiplex, corresponding 6 subcarriers of PHICH group, be mapped on 6 subcarriers in 3 resource groups, above-mentioned 6 subcarriers are comprised of the first two subcarrier of each target resource group, perhaps, are comprised of latter two subcarrier of each target resource group.
That is to say, when Cyclic Prefix is extended cyclic prefix, 3 corresponding two PHICH groups of resource group, when Cyclic Prefix is the regular circulation prefix, 3 corresponding PHICH groups of resource group;
OFDM symbolic number as transmission PHICH group is N, and when unicast transmission, N is 1 or 3; And when multicast transmission, N is 1 or 2, is numbered 3 resource groups corresponding to PHICH group of m, the resource group # is i (i=0,1,2) send mode such as following formula (1) on the OFDM symbol that is numbered l ' in target-subframe of the resource group i that, PHICH group m is corresponding:
Particularly, when the number as the OFDM symbol that transmits PHICH is 2, suppose that 2 PHICH groups (#0, #1) are arranged, after shining upon according to formula (1), the concrete mapping as shown in Figure 1, wherein:
The time-domain position of 3 resource groups that PHICH group # 0 is corresponding is:
In the situation of M=0,
When i=0,
When i=1,
When i=2,
The time-domain position of 3 resource groups that PHICH group # 1 is corresponding is:
In the situation of m=1;
When i=0,
When i=1,
When i=2,
Can find out that when N=2,2 PHICH group is mapped on the identical time-domain position, when Cyclic Prefix is extended cyclic prefix, 3 corresponding 2 PHICH groups of resource group, the so on average load on the OFDM symbol of mapping; But, when Cyclic Prefix is the regular circulation prefix, 3 corresponding 1 PHICH groups of resource group.Like this, the situation shown in Fig. 1 will occur, mapping does not reach the effect of the load on the average OFDM symbol, so that the system transmissions hydraulic performance decline.
Yet, the technical scheme that can address this problem is not yet proposed at present.
