Description

A kind of many subframe scheduling methods, base station, terminal and system

Technical field

The present invention relates to the communications field, refer to especially a kind of many subframe scheduling methods, base station, terminal and system.

Background technology

Long Term Evolution (Long Term Evolution, abbreviation LTE) uplink physical channel of system comprises Physical Random Access Channel (Physical Random Access Channel, referred to as PARCH), Physical Uplink Shared Channel (Physical Uplink Shared Channel, referred to as PUSCH), Physical Uplink Control Channel (Physical Uplink Control Channel, referred to as PUCCH).The up employing single carrier OFDM technology of LTE, reference signal and data are that the mode by TDM is together with multiplexing.

And the down physical channel of LTE comprises Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH), Physical Downlink Control Channel (Physical Uplink Control Channel, referred to as PDCCH), Physical Broadcast Channel (Physical Broadcast Channel, be called for short PBCH), Physical Multicast Channel (Physical Multicast Channel, be called for short PMCH), Physical Control Format Indicator Channel (Physical Control Format Indicator Channel, be called for short PCFICH), physical mixed ARQ indicating channel (Physical Hybrid ARQ Indicator Channel, be called for short PHICH), strengthen Physical Downlink Control Channel (Enhanced Physical Downlink Control Channel, be called for short EPDCCH).

In LTE system, uplink and downlink control information is transmitted respectively by PUCCH and PDCCH.Wherein PUCCH is for transmitting uplink control information (Uplink Control Information, referred to as UCI), comprise dispatch request (Scheduling Request, referred to as SR), Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH) correct/error response message (positive acknowledgement/negative acknowledgement, referred to as HARQ-ACK/NACK) and the downlink channel condition information (Channel State Information, referred to as CSI) of UE feedback.Wherein, CSI comprises again three kinds of forms: channel quality indication (Channel Quality Indication, referred to as CQI), pre-coding matrix indication (Precoding Matrix Indicator, referred to as PMI), order indication (Rank Indication, referred to as RI).The transmission of CSI has two kinds of modes: cycle CSI and aperiodic CSI, wherein cycle CSI is that after eNB configures by high-level signaling, UE sends in a fixed manner according to certain time interval, and aperiodic, CSI was that eNB triggers by DCI, UE sends after receiving DCI.

PDCCH is used for transmitting Downlink Control Information (Downlink Control Information, referred to as DCI), DCI is mainly used in dispatching PDSCH and PUSCH, UE receives after DCI, according to the indication of DCI, receive evolution base station (Evolved-Node B, abbreviation eNB) PDSCH sending, or to eNB, send PUSCH according to the indication of DCI.In DCI, mainly comprise resource indication information (Resource block assignment), modulation and encoding scheme (Modulation and coding scheme, be called for short MSC), descending allocation index (Downlink Assignment Index, be called for short DAI), channel condition information request (Channel State Information request), the cyclic shift of demodulated reference signal and quadrature mask (Cyclic shift for DM RS and OCC index), transmission block size (Transport Block Size, be called for short TBS) etc., UE receives after above-mentioned DCI, according to the indication of DCI, receive the PDSCH that eNB sends, or send PUSCH to eNB.

Above-mentioned TBS represents the size of transmission block, in LTE system, in order to improve system spectral efficiency, introduced multiple-input and multiple-output (Multiple-Input Multiple-Output, be called for short MIMO) technology, send and receive end at a wireless system all adopts many antenna elements, utilize the abundant Spatial Multi-Dimensional characteristic of wireless scatter channel, in the mode of many inputs/many outputs, work, reach the effect that improves system channel capacity.After introducing MIMO, each carrier wave is supported a plurality of transmission blocks multiplexing transmission of (Transport Block is called for short TB), and eNB need to be by the TBS notice UE of each TB.

And DAI is called UL DAI when DCI scheduling UE sends sub-frame of uplink, in the sub-frame of uplink that expression UE will send, need the number of the ACK of feedback; And DAI is called DL DAI when DCI scheduling UE receives descending sub frame, represent that current subframe is which descending sub frame of dispatching in scheduling window.

Scheduling in existing LTE system has two kinds of dynamic dispatching and semi-persistent schedulings, and wherein dynamic dispatching is that eNB dispatches UE according to existing communication requirement, and eNB sends a DCI, and UE receives a PDSCH or sends a PUSCH according to current DCI; Semi-persistent scheduling (semi-persistance scheduling, be called for short SPS) refer to that eNB activates semi-persistent scheduling by DCI, after semi-persistent scheduling activates, UE receives PDSCH or sends PUSCH according to fixing interval, and re-use DCI notice without eNB, until eNB is used DCI deexcitation semi-persistent scheduling, but in existing LTE standard, the maximum MCS of SPS scheduling is restricted to 15.

In the LTE of Rel-9 version agreement, for further improving system spectral efficiency, introduced descending alone family multiple-input and multiple-output (Single users Multiple-Input Multiple-Output, be called for short SU-MIMO) technology, in existing LTE agreement, eNB transmit antenna quantity mostly is 8 most, the streams of code words quantity of transmission is 2 to the maximum, and in the LTE of Rel-10 version agreement, introduced up SU-MIMO technology, in existing LTE agreement, UE uplink antenna amount mostly is 4 most, and the streams of code words quantity of uplink is 2 to the maximum.

In LTE standard, the transmission of 2 streams of code words in a subframe can be dispatched by a DCI in base station, the MCS of 2 streams of code words that are scheduled and new data indication (New Data Indicator, be called for short NDI) and redundancy versions (Redundancy version, abbreviation RV) can indicate respectively.

In LTE system, in dynamic dispatching, a DCI can only trigger UE and receive a PDSCH or send a PUSCH, and in fact for low speed mobile subscriber, when user has continuous data transmission, can in a plurality of subframes, use identical scheduling parameter to transmit, now the control overhead of dynamic transmission be larger, has reduced systematic function; And in SPS scheduling, owing to being subject to maximum MCS, be 15 restriction, cannot use high order modulation, cannot the larger user's transmission of supported data amount.

And for higher spectrum efficiency is provided for user, be necessary to reduce the control overhead of base station scheduling.For this reason, the concept of many subframe schedulings is suggested, and a plurality of sub-frame of uplink or descending sub frame are dispatched by a DCI in base station, and UE sends upstream data in downlink data receiving or a plurality of sub-frame of uplink of being scheduled in a plurality of descending sub frames that are scheduled.

And the shortcoming of many subframe schedulings is exactly the scheduling parameter of a plurality of subframes of being scheduled, as MCS, TBS etc. can only be consistent, and cannot change according to channel circumstance, have reduced the flexibility of scheduling.In order to guarantee the advantage of the saving control overhead of many subframe schedulings, the flexibility that need to improve many subframe schedulings.
