Description

A kind of transmission of up-downgoing schedule information, detection method and device

Technical field

The present invention relates to wireless communication technology field, more particularly to a kind of transmission of up-downgoing schedule information, detection Method and device.

Background technology

Mobile Internet is overturning conventional mobile communications business model, provides the user unprecedented use Experience, profound influence the every aspect of people's Working Life.Mobile Internet will promote human society information The further upgrading of interactive mode, provide the user augmented reality, virtual reality, ultra high-definition (3D) video, The more abundant business experience such as mobile cloud.The further development of mobile Internet will bring following mobile flow Surpass thousand times of growths, promote a new round for mobile communication technology and industry to change.And Internet of Things then extends movement The service range of communication, people and thing, thing and thing intelligent interconnection are extended to from person to person's communication, makes mobile communication Technological penetration is to more wide industry and field.Future, portable medical, car networking, smart home, work Industry control, environmental monitoring etc. will promote Internet of Things application explosive growth, and number will be accessed with hundred billion equipment Network, realize really " all things on earth interconnection ".Meanwhile the equipment connection of magnanimity and diversified Internet of Things industry Business can also bring new technological challenge to mobile communication.

With the lasting appearance of new business demand and abundant, future mobile communication system is proposed higher Performance requirement, for example, it is higher peak rate, more preferable Consumer's Experience speed, smaller time delay, higher Energy consumption efficiency of reliability, higher spectrum efficiency and Geng Gao etc., and need to support more users' accesses with And use miscellaneous service type.In order to support the connection of each Terminal Type of enormous amount and different service class Type, the flexible configuration of up-downgoing resource turn into a main trend of technology development.Following system resource can root According to the difference of business, different subbands, and the different TTI of partition length on subband are divided into (Transmission Time Interval, Transmission Time Interval), to meet multiple business demand.

Fig. 1 is the structural representations of Frame structure type 1, existing LTE (Long Term Evolution, Long Term Evolution) FDD (Frequency Division Duplex, FDD) system uses frame structure (frame Structure type 1, abbreviation FS1), its structure is as shown in Figure 1.In FDD system, uplink and downlink Transmission uses different carrier frequencies, and uplink and downlink transmission uses identical frame structure.In each carrier wave On, the radio frames of a 10ms length include 10 1ms subframes, and each subframe is interior by being divided into two The time slot of 0.5ms length.A length of 1ms during the TTI that uplink and downlink data are sent.

Fig. 2 is Frame structure type 2 (for 5ms switch-point periodicity) structural representation Figure, existing LTE TDD (Time Division Duplex, time division duplex) system use frame structure (frame Structure type 2, abbreviation FS2), as shown in Figure 2.In a tdd system, uplink and downlink transmission makes With the different subframes or different time-gap in identical frequency.Each 10ms radio frames are by two 5ms in FS2 Field is formed, and the subframe of 5 1ms length is included in each field.Subframe in FS2 is divided into three classes：Under Row subframe, sub-frame of uplink and special subframe, each special subframe is by DwPTS (Downlink Pilot Time Slot, downlink transfer time slot), GP (Guard Period, protection interval) and UpPTS (Uplink Pilot Time Slot, upstream transmission time slot) three parts composition.Wherein DwPTS can transmit descending pilot frequency, under Row business datum and descending control signaling；GP does not transmit any signal；UpPTS only transmit Stochastic accessing and SRS (Sounding Reference Symbol, detection reference signal), it is impossible to transmit uplink service or up Control information.At least one descending sub frame and at least one sub-frame of uplink are included in each field, and at most 1 special subframe.The 7 kinds of ascending-descending subframes configuration modes supported in FS2 are as shown in table 1.
