Embodiment
The embodiment of the invention is according to the configuration information of special time slot, determine the time period length and the frequency range length of LTE-A resource, select a part of resource as the LTE-A resource from special time slot, indication LTE-A terminal receives the LTE-A downlink information in the LTE-A of special time slot resource.Owing to can indicate the resource of LTE-A terminal bearing downlink information, make the LTE-A terminal can receive the LTE-A downlink information.
Wherein, the structure of special time slot comprises DwPTS (downlink pilot time slot, descending pilot frequency time slot), GP (guard period, protection at interval) and UpPTS (uplink pilot time slot uplink pilot time slot), referring to Fig. 1.The time period length of DwPTS, GP and UpPTS is not changeless, time period length according to DwPTS, GP and UpPTS is different, and the configuration information that multiple special time slot is arranged accordingly is that network side is selected a kind of configuration information according to the requirement that the sub-district covers from the configuration information of multiple special time slot.
The LTE-A downlink information comprises high-level signaling and data, specifically includes but not limited in the following message one or more:
Measurement pilot frequency, relay signaling, data.
Can accurately determine the LTE-A resource according to time period and frequency.
Since the LTE-A system can be compatible the LTA system, so can have LTE-A terminal and LTE terminal simultaneously in the LTE-A system.The LTE-A terminal is to support the terminal of LTE-A system and LTE system, and the LTE terminal is to support the terminal of LTE system.
Below in conjunction with Figure of description the embodiment of the invention is described in further detail.
As shown in Figure 2, the device of indicating terminal resource bearing downlink information comprises in the embodiment of the invention LTE-A system: resource determination module 10, processing module 20 and indicating module 30.
