Description
Technical field
The present invention relates to fields of communication technology, particularly relate to indicating means, the determination side of a kind of configuration information of frame structure
Method and device.
Background technique
In order to better meet business demand and several scenes covering, a variety of uplink and downlink proportions are defined in existing TD-LTE
To support the uplink and downlink business of different ratio, and a variety of special subframe configurations are defined to support different cell coverage areas.
In order to realize that more flexible frame structure configures and reduce propagation delay time, 3GPP NR to the basic unit of frame structure into
Discussion is gone.Determine a subframe unit may comprising full downlink transfer, full uplink or contain at least one uplink biography
Defeated part and a downlink transfer part.I.e. there may be 3 kinds of subframe types：Full sub-frame of uplink, full downlink sub-frame and two-way
It transmits subframe (existing simultaneously uplink and downlink transfer).These three subframes can flexibly be combined to be formed frame structure with
Meet different business scene demand.Compared to LTE, two-way subframe is introduced in 3GPP NR, using two-way subframe, user can be with
Uplink scheduling transmission and quick feeding back ACK/nack message are fast implemented, realizes lower propagation delay time and faster link
Adaptive process, lifting system performance.For two-way subframe, to avoid uplink and downlink from interfering, general row transmission and uplink portion
/ insertion protection time slot (guard period, GP), not according to the function of application scenarios and uplink and downlink transfer
Together, the time span of the length of GP and position and uplink and downlink transfer all should can be with flexible configuration.Therefore two-way
Subframe is also likely to be present a variety of flexible configurations.The signal of several possible two-way sub-frame configurations is set forth in Fig. 1 to Fig. 4
Figure；Wherein, D is the OFDM symbol of downlink transfer, and U is the OFDM symbol of uplink.
In general, the flexible frame structure of NR can be by the way that flexibly dynamic mode indicate or by semi-static completely
Mode indicate.Common complete flexibly dynamic indicating means can be：Under the downlink control section instruction that subframe starts
The initial position of row duration and uplink.Matching for subframe is determined by indicating these contents in each subframe
Set structure.Semi-static indicating mode can be similar to LTE, define in advance to a frame (including multiple subframes) a variety of possible
Configuration mode, then UE broadcast configuration type is given in base station.Such as in TD-LTE, defines 7 kinds of uplink-downlink configurations and 9 kinds special
Sub-frame configuration.TD-LTE system informs UE frame structure type [1] by broadcast uplink-downlink configuration and special subframe configuration.
Currently, the completely flexible dynamic indication method of NR frame structure can carry out completely dynamic configuration to frame structure, still
The initial position of the downlink control section indicating downlink duration and uplink that need to start in each subframe, signaling
Expense is larger.By taking a subframe includes 14 OFDM symbols as an example, to realize completely flexible configuration, 4bit is needed to indicate down
Row duration and 4bit instruction uplink start to be position, and each subframe needs 8bit to indicate information.Semi-static instruction
Method usually has lower signaling instruction expense, because generally can determine whether limited kind of frame structure configuration, (uplink and downlink is with when GP
Configuration etc.), by indicating limited kind of configuration.But being semi-statically configured can only match comprising limited uplink and downlink,
Two-way subframe type and subframes combine mode, it may not be possible to the characteristic and influence propagation delay time of preferable matching business.
