Description
Technical field
The present invention relates to field of communication technology, in particular to a kind of blind examination down physical layer control signaling method,
Device, communication equipment and computer readable storage medium.
Background technique
5th third-generation mobile communication technology contain enhanced mobile broadband (Enhance Mobile Broadband, eMBB),
Highly reliable low time delay (Ultra-reliable and Low Latency Communications, URLLC) and magnanimity machine
Type communication (mMTC).The job of 5G NR (New Radio) has passed through in RAN#75 meeting at present, the project
Need to standardize the technology of eating dishes without rice or wine of eMBB and URLLC.EMBB business demand is high-speed, is not wanted strictly to reliability and time delay
It asks；For URLLC business, needing to meet 3GPP, (3rd Generation Partnership Project, the third generation are closed
Make Partnership Program) propose reliability and delay requirement.In order to meet the requirement of high reliability and low time delay, URLLC business is needed
It to dispatch, i.e., can also be dispatched at once in the intermediate time that an eMBB sends interval in time.It is different from general eMBB data
, URLLC data can generally select to occupy biggish bandwidth on frequency domain due to needing ultralow time delay, to reduce in time domain
On resource occupation, such receiving end can be received within the period short as far as possible reconciliation adjusting data.In the case where resource-constrained,
URLLC data may occupy the running time-frequency resource of scheduled eMBB data, also punch eMBB data, with higher prior
Grade occupies resource and carries out data transmission.
In order to adapt to the requirement of URLLC low time delay, and reduction URLLC terminal blind examination down physical layer control information
The power consumption of (Downlink Control Information, DCI), a kind of feasible scheme are to carry out half for URLLC business
Static scheduling, i.e. base station carry out first resource scheduling by sending a down physical layer control signaling, are designated as terminal point
The multiple running time-frequency resource positions in time domain period profile matched, terminal can be in multiple running time-frequency resources after DCI of blind examination
Data are received or sent at position.As shown in Figure 1, be designated as in DCI terminal distribution frequency resource position be resource block 8 to
Resource block 15, and the transmitting continuous OFDM of a data (Orthogonal Frequency Division Multiplexing, just
Hand over frequency division multiplexing symbol) symbol data is 2 OFDM symbols, the time interval of the adjacent transmission of data twice is 5 OFDM symbols,
The quantity of the distributed running time-frequency resource position of primary scheduling is 5.
But when a semi-persistent scheduling terminates, when terminal should start blind examination DCI, if in semi-static knot
First after beam can carry URLLC control information OFDM symbol at start blind examination DCI, then need terminal semi-static
Just start blind examination DCI after finishing scheduling, if the data of terminal available for transmission, needs after DCI is demodulated successfully
Upstream data or demodulation downlink data can be sent, this can generate biggish time delay.
