Description

Communication method based on frame structure
Technical Field
The invention relates to the technical field of communication, in particular to a communication method based on a frame structure.
Background
Existing 4G and 4.5G mobile communication technologies are based on LTE (Long Term Evolution) and LTE-a (LTE-Advanced) radio access technologies, time-frequency resource granularity, frame structures, and the like. For example, the maximum single carrier bandwidth that can be supported by the current LTE system is 20MHz, and if a larger bandwidth is to be supported, only Carrier Aggregation (CA) is used. In addition, the current frame structure mainly includes: FDD (Frequency Division duplex) frame structures, TDD (Time Division duplex) frame structures, and dynamic frame structures used by LAA (LTE Assisted Access) unlicensed carriers. Regardless of the frame structure, the subframe structure includes 10 subframes, each subframe is 1ms, each subframe includes two slots (one slot is 0.5 ms), and each slot includes 7 symbols. In the frequency domain, in the LTE system, the subcarrier spacing is mainly 15KHz, and one RB (Resource Block) includes 12 subcarriers. A new 3.75KHz sub-carrier spacing is proposed in NB-IoT (Narrow Band Internet of things over cellular), and the carrier bandwidth of NB-IoT is only 180 KHz.
In terms of resource allocation, both the FDD frame structure and the TDD frame structure use 1ms subframes as Time-domain scheduling granularity, except that when DwPTS (Downlink Pilot Time Slot) in a special subframe in the TDD frame structure is used for transmitting data, the Time-domain scheduling granularity is less than 1 ms. Similarly, in the frame structure used by the LAA unlicensed carrier, the downlink scheduling time domain granularity which multiplexes DwPTS as a partial subframe also appears, and meanwhile, the scheduling granularity of the 1ms whole subframe is also used. In the FDD frame structure and the TDD frame structure, except for the special subframe in the TDD frame structure, which has both downlink transmission time and uplink transmission time, other subframes are time-domain separated or frequency-domain separated for uplink transmission or downlink transmission. In the partial subframe of the frame structure used by the LAA unlicensed carrier, the first half of the same subframe is downlink transmission time, and the second half of the same subframe is uplink transmission time.
In addition, in terms of uplink scheduling, the time interval between the UL grant (uplink scheduling command) used for uplink transmission in the LTE system and the subframe where uplink data is actually transmitted is generally 4 ms. Whereas HARQ (Hybrid Automatic repeat request) ACK/NACK feedback can generally be transmitted 4ms or more after the corresponding data transmission.
It can be seen that, the current frame structure and the granularity of frequency domain resources both make the resource allocation inflexible, and the time intervals of the uplink scheduling mechanism and the HARQ feedback mechanism and the like make the time delay larger, and the 20MHz bandwidth also does not meet the requirement of high bandwidth.
The main scenes of the future 5G communication include the following three scenes: eMBBs (enhanced Mobile Broadband networks), mMTC (massive Machine Type Communication), and URLLC (Ultra-Reliable and Low Latency Communication). The three scenarios are different in the types of services and the requirements. Such as: two main indexes of the eMB service are high bandwidth and low time delay, the eMB service can support large bandwidth of 100MHz in future high-frequency communication, the whole bandwidth is probably directly allocated to a user for use at a certain moment, and the uplink scheduling time delay and the HARQ feedback time delay can bring time delay influence; the mMTC service needs a narrow-band service, and needs a long battery life, so that the service needs a frequency domain with smaller granularity and a time domain resource with wider granularity; for URLLC service, it is also necessary to reduce the delay impact caused by uplink scheduling delay and HARQ feedback delay.
That is to say, due to diversification of services, a current fixed frame structure, a fixed frequency domain resource granularity and a time domain resource granularity may cause a larger uplink scheduling delay and a longer HARQ feedback delay, and a smaller carrier bandwidth may not meet the diversified requirements of the services, and it is expected that in the future 5G communication, it is flexible enough that any one resource may be dynamically scheduled to be used at any time, which are technical problems to be solved urgently.
Disclosure of Invention
Based on at least one of the above technical problems, the present invention provides a new frame structure-based communication method, so that the time length of each time unit in the frame structure can be flexibly configured according to the actual communication scenario, the flexibility of resource scheduling is improved, and the service requirements in the 5G communication scenario are met.
In view of the above, according to a first aspect of the present invention, a frame structure based communication method applicable to a terminal is provided, where the frame structure includes a first downlink time unit, a guard time unit located after and adjacent to the first downlink time unit, an uplink time unit located after and adjacent to the guard time unit, and a second downlink time unit located after and adjacent to the uplink time unit, and time lengths of the first downlink time unit, the guard time unit, the uplink time unit, and the second downlink time unit are configurable, the method includes: acquiring time length configuration information of the first downlink time unit, the protection time unit and the uplink time unit; and communicating with a base station according to the time length configuration information of the first downlink time unit, the protection time unit and the uplink time unit.

It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
Fig. 1 shows a schematic diagram of a frame structure in a communication system according to an embodiment of the invention.
As shown in fig. 1, a frame structure in a communication system according to an embodiment of the present invention includes: a first downlink time unit DL1, a guard time unit GP located after and adjacent to the first downlink time unit DL1, an uplink time unit UL located after and adjacent to the guard time unit GP, and a second downlink time unit DL2 located after and adjacent to the uplink time unit UL, wherein the time lengths of the first downlink time unit DL1, the guard time unit GP, the uplink time unit UL, and the second downlink time unit DL2 are configurable.
In the technical scheme, because the frame structure includes the first downlink time unit DL1, the guard time unit GP, the uplink time unit UL and the second downlink time unit DL2, which have configurable time lengths, when communication is performed, the time lengths of the first downlink time unit DL1, the guard time unit GP, the uplink time unit UL and the second downlink time unit DL2 can be flexibly configured according to an actual communication scenario (such as a type of a communication service), so that a large uplink scheduling delay and a long HARQ feedback delay caused by adopting a fixed frame structure can be avoided, the flexibility of resource scheduling can be improved, service requirements in a 5G communication scenario are met, and the resource utilization rate is improved.
On the basis of the frame structure shown in fig. 1, the present invention proposes the following configuration:
the first configuration mode is as follows:
the time length of the first downlink time unit DL1 and the guard time unit GP is configured to be 0, and the time length of the uplink time unit UL is configured to be not 0. The uplink time unit UL is used for the terminal to transmit uplink data and/or uplink control signaling and/or uplink reference signal and/or random access preamble.
Specifically, the uplink time unit is used for the terminal to transmit uplink data and/or uplink control signaling and/or uplink reference signal and/or random access preamble based on the randomly selected frequency domain resource or the frequency domain resource selected based on the previous scheduling condition.

As shown in fig. 2A, when the time length of the second downlink time unit DL2 is configured to be other than 0, if the uplink time unit UL is used for the terminal to transmit uplink data, the second downlink time unit DL2 is used for the base station to transmit HARQ feedback for the uplink data received in the current frame structure or the frame structure before the current frame structure.
