DwPTS in the special subframe is reserved as a downlink transmission area, UpPTS is reserved as an uplink transmission area, and GP is a guard interval. The total length of DwPTS, GP and UpPTS is 1ms, and the lengths of DwPTS and UpPTS are available, as shown in Table 1:
TABLE 1 Special subframe configuration, DwPTS, GP and UpPTS Length
The GP does not transmit any signal, thereby providing protection between the uplink and the downlink and avoiding cross interference between the uplink and the downlink. When the normal CP is adopted, 10 kinds of DwPTS, GP and UpPTS length configurations are supported totally, and when the extended CP is adopted, 8 kinds of length configurations are supported totally and indicated by high-layer signaling. The length of the UpPTS is fixed, and only one symbol and two symbol lengths are supported, so that more options are avoided, and the system design is simplified.
TABLE 2 uplink and downlink subframe ratio
Under the condition of different uplink and downlink subframe ratios, if the UE receives a PHICH (Physical Hybrid-ARQ Indicator Channel) in subframe n, HARQ information (including ACK and NACK) carried by the PHICH corresponds to a PUSCH transmitted by the UE in uplink subframe n-k. Where the values of k are shown in Table 3 below.
