TECHNICAL FIELD
The present document relates to the mobile communication technology, and particularly, to a multi-subframe scheduling method, device and system.
BACKGROUND OF THE RELATED ART
Uplink physical channels of a Long Term Evolution (LTE) system include: a Physical Random Access Channel (PRACH), a Physical Uplink Shared Channel (PUSCH) and a Physical Uplink Control Channel (PUCCH). The single carrier Orthogonal Frequency Division Multiplexing (OFDM) technology is used in the uplink of the LTE, reference signals and data are multiplexed by means of Time Division Multiplexing (TDM).
And downlink physical channels of the LTE system include: a Physical Downlink Shared Channel (PDSCH), a Physical Downlink Control Channel (PDCCH), a Physical Broadcast Channel (PBCH), a Physical Multicast Channel (PMCH), a Physical Control Format Indicator Channel (PCFICH), a Physical Hybrid ARQ Indicator Channel (PHICH) and an Enhanced Physical Downlink Control Channel (EPDCCH).
In the LTE system, uplink control information is transmitted by a PUCCH and downlink control information is transmitted by a PDCCH. Wherein, the PUCCH is used for transmitting Uplink Control Information (UCI), the UCI includes a Scheduling Request (SR), positive acknowledgement/negative acknowledgement (HARQ-ACK/NACK) of a Physical Downlink Shared Channel (PDSCH) and downlink Channel State Information (CSI) fed back by User Equipment (UE). Wherein, the CSI includes three forms: a Channel Quality Indication (CQI), a Precoding Matrix Indicator (PMI) and a Rank Indication (RI). Sending of the CSI includes two ways: periodic CSI and aperiodic CSI, wherein the periodic CSI is that, after an Evolved-Node B (eNB) performs configuration through upper layer signaling, the UE sends the CSI in a fixed way according to a certain time interval, and the aperiodic CSI is that the eNB performs triggering through DCI, and the UE performs sending after receiving the DCI.
In the LTE system, uplink reference signals are divided into a Demodulation Reference Signal (DMRS) and a Sounding Reference Signal (SRS). Wherein, the DMRS is divided into a PUCCH-specific demodulation reference signal and a PUSCH-specific demodulation reference signal, which are respectively used for different channel transmissions. The DMRS is mainly used for estimation of uplink channels and coherent detection and demodulation of the eNB base station terminal; and the SRS is mainly used for measurement of the uplink channels, so that the eNB performs frequency selectivity scheduling. In order to support such frequency selectivity scheduling, the UE is required to perform measurement on larger bandwidths, and generally it will exceed the bandwidth of the data transmission, therefore, the SRS is a “broadband” reference signal. The SRS is divided into two kinds: a periodic SRS and an aperiodic SRS, wherein, the periodic SRS is an SRS configured by the system and sent according to a certain period, and the aperiodic SRS is triggered by the base station through DCI and is sent after the UE receives the DCI of the base station triggering the aperiodic SRS.
The PDCCH is used for transmitting Downlink Control Information (DCI), the DCI is mainly used for scheduling the PDSCH and PUSCH, that is, after receiving the DCI, the UE receives the PDSCH sent from an Evolved-Node B (eNB) according to an indication of the DCI, or sends the PUSCH to the eNB according to the indication of the DCI. The DCI mainly includes: resource indication information (Resource block assignment), a Modulation and Coding Scheme (MCS), a Downlink Assignment Index (DAI), a Channel State Information request, a Cyclic shift for DMRS and Orthogonal Cover Code (OCC) index and a Transport Block Size (TBS) and so on. After receiving the above DCI, the UE receives the PDSCH sent from the eNB according to indication information in the DCI, or sends the PUSCH to the eNB.
The above TBS represents a size of a transport block, in the LTE system, in order to improve the system spectrum efficiency, the Multiple-Input Multiple-Output (MIMO) technology is introduced, that is, multi-antenna units are used at both a sending end and a receiving end of a wireless system, with abundant space multidimensional characteristics of wireless scatter channels, it is to work by means of multiple-input end/multiple-output end, thereby achieving an effect of improving the system channel capacity. After the MIMO is introduced, each carrier supports multiplex transmission of a plurality of Transport Blocks (TBs), and in this case, the eNB is also required to notify the UE of a TBS of each TB.
And when the UE is scheduled to send uplink subframes through the DCI, the DAI is called as an uplink DAI (UL DAI), which is used for representing the number of ACKs required to be fed back in the uplink subframes that will be sent by the UE; and when the UE is scheduled to receive downlink subframes through the DCI, the DAI is called as a downlink DAI (DL DAI), which is used for representing that a currently received subframe is which downlink subframe that is scheduled in a scheduling window.
In the LTE system in the related art, scheduling includes two kinds: dynamic scheduling and semi-persistence scheduling. Wherein, the dynamic scheduling is: the eNB scheduling the UE according to the related communication requirements, that is, the eNB sending a piece of DCI, and the UE receiving one PDSCH or sending one PUSCH according to the current DCI; the semi-persistence scheduling (SPS) is: the eNB activating the semi-persistence scheduling through the DCI, after the semi-persistence scheduling is activated, the UE receiving the PDSCH or sending the PUSCH according to a fixed interval, and the eNB not needing to give a notification through the DCI until the eNB deactivates the semi-persistence scheduling through the DCI, moreover, in the LTE standard in the related art, the maximum MCS of the SPS scheduling is limited to 15.
In the LTE system, at present, in the dynamic scheduling, a piece of DCI can only trigger the UE to receive one PDSCH or send one PUSCH. However, in fact, with respect to a low-speed mobile user, when the user has continuous data to be transmitted, if the same scheduling parameter can be used in a plurality of subframes to perform transmission, at this point, the control overhead of the dynamic transmission will be higher, thereby reducing the system performance; and in the SPS scheduling, due to the limitation that the maximum MCS is 15, high order modulation cannot be used at present, thus user transmission with a larger data volume cannot be supported.

PREFERRED EMBODIMENTS OF THE INVENTION
FIG. 1 is a flow chart of a multi-subframe scheduling method according to the embodiment of the present document, and as shown in FIG. 1, the following steps are included.
In step 100, a base station side schedules transmission of a plurality of subframes through a piece of DCI.
In the step, the base station side schedules a plurality of uplink subframes or downlink subframes at a time through a piece of DCI, and the base station side sends data in the plurality of downlink subframes scheduled, or receives data in the plurality of uplink subframes scheduled.
In step 101, according to the acquired multi-subframe scheduling mode and scheduling parameters, a UE receives and sends the plurality of subframes according to an indication of the DCI.
In the step, in accordance with the acquired multi-subframe scheduling mode and scheduling parameters, according to the indication of the DCI, the UE receives data of the plurality of downlink subframes scheduled, or sends data of the plurality of uplink subframes scheduled.
Before the step, it also includes the UE acquiring the multi-subframe scheduling mode and scheduling parameters, and a specific way includes: the base station side and the UE pre-appointing the multi-subframe scheduling mode and scheduling parameters, and/or the base station side sending the multi-subframe scheduling mode and scheduling parameters to the UE through upper layer signaling, and/or the base station side indicating the multi-subframe scheduling mode and scheduling parameters in the DCI. Specifically:
in step 101, the UE acquiring the multi-subframe scheduling mode and scheduling parameters is: the base station side and the UE pre-appointing the multi-subframe scheduling mode and scheduling parameters, that is, setting various scheduling modes with regard to multi-subframe scheduling and scheduling parameters corresponding to all the scheduling modes at the base station side and the UE respectively in advance. Specific descriptions will be made through the examples below.
(1) The preset scheduling mode is the base station scheduling a plurality of continuous subframes, and the preset scheduling parameters will indicate the number of subframes scheduled.
(2) The preset scheduling mode is the base station scheduling a plurality of discontinuous subframes, and the preset scheduling parameters will indicate subframe intervals of the plurality of subframes scheduled and the total number of subframes scheduled.
(3) With respect to scheduling parameters of a plurality of subframes, it can be preset as that:
it is to keep the scheduling parameters of all subframes scheduled identical;
or, it is to indicate changes of scheduling parameters of user data in different subframes by means of the indication of the DCI;
or, the UE and the base station side pre-appoint an adjustment step size and an adjustment condition for the scheduling parameter, therefore, when the base station schedules the UE to send a PUSCH, the UE automatically adjusts the scheduling parameter according to the appointed adjustment step size, according to the appointed adjustment condition; and when the base station schedules the UE to receive a PDSCH, the base station adjusts parameters of a plurality of PDSCHs scheduled according to the appointed adjustment condition, and the UE receives the PDSCH according to an appointment with the base station. Here, the base station side can indicate whether the automatic adjustment is allowed through the upper layer signaling or DCI.
The scheduling parameters include all the scheduling parameters contained in the indication of the DCI.
(4) The preset scheduling mode is the plurality of subframes scheduled containing different types of subframes, and the preset scheduling mode also will indicate a way of how to process, for example, only the subframes of the same type are scheduled in the multi-subframe scheduling, or scheduled subframes are selected based on a transmission mode, that is, according to the transmission mode of the subframe, it is to select whether to schedule subframes based on different transmission modes and so on. Here, different types of subframes can be that signal contents borne by the subframes are different, or types of subframes are different and so on.
Wherein, different types of subframes can be but not limited to the following divisions: a subframe with UCI transmission and a subframe without UCI transmission; and/or an MBSFN subframe and a non-MBSFN subframe; and/or an SPS subframe and a non-SPS subframe; and/or a subframe with SRS transmission and a subframe without SRS transmission. Preferably, it can be set correspondingly according to different cases, for example,
if the plurality of subframes scheduled contain SPS subframes and subframes with aperiodic CSI transmission, the following processing mode can be preset: the SPS can only be scheduled by means of single-frame scheduling; or, activation and release of the SPS can only be scheduled by means of single-frame scheduling, but an SPS subframe in an activated period can be scheduled by means of multi-subframe scheduling; or, aperiodic CSI cannot be triggered through the multi-subframe scheduling; or, the subframes in the multi-subframe scheduling contain SPS and aperiodic CSI subframes, and the SPS and aperiodic CSI subframes are located in preset appointed locations in the subframes scheduled (the appointed locations also can be indicated by the base station to the UE through an indication).
Whether the plurality of subframes scheduled contain the SPS subframe can be judged through a preset condition, for example, whether the DCI is scrambled by SPS RNTI, if it is judged that the DCI is scrambled by the SPS RNTI, it indicates that the plurality of subframes contain the SPS subframe; for another example, whether a location of the SPS subframe is in the plurality of subframes scheduled, if it is judged that the location of the SPS subframe is in the plurality of subframes scheduled, it indicates that the plurality of subframes contain the SPS subframe and so on, and more examples will not be given here.
Alternatively,
When the subframes in the multi-subframe scheduling contain the SPS subframe, and the DCI supports multi-stream transmission, a TB index of the SPS subframe is determined through the following way:
when the DCI supports the multi-stream transmission, data of the SPS correspond to a preset TB index;
or, when the DCI supports the multi-stream transmission, the TB index corresponding to the data of the SPS is determined according to indication signaling of the base station.
When the subframes in the multi-subframe scheduling contain the SPS, a TBS of the SPS subframe is determined through the following way:
the TBS of the SPS subframe and TBSs of the other subframes scheduled are determined according to a preset proportion;
or, the TBS of the SPS subframe is a pre-appointed fixed value.
When the subframes in the multi-subframe scheduling contain UCI or an aperiodic CSI subframe, a TBS of the aperiodic CSI subframe is determined through the following way:
a TBS of a subframe in which the UCI is located and a TBS of a subframe in which aperiodic CSI is located are in a preset proportion relationship with other subframes;
or, it is to preset that the TBS of the subframe in which the aperiodic CSI is located is limited to 0;
or, when the DCI supports the multi-stream transmission, the aperiodic CSI uses a preset fixed codebook and port;
or, the TBS of the subframe in which the UCI is located is a pre-appointed fixed value.
Particularly, in a TDD system, when the base station performs multi-subframe scheduling, a relationship between a UL DAI and a plurality of subframes scheduled can be preset as that:
the UL DAI corresponds to an HARQ-ACK feedback of the first uplink subframe in the multi-subframe scheduling;
or, the UL DAI corresponds to an uplink subframe corresponding to the largest number of downlink subframes in the plurality of uplink subframes scheduled;
or, the UL DAI is applied to all uplink subframes, each subframe corresponds to a preset same value;
or, the UL DAI corresponds to a preset group of DAI values.
In the TDD system, when the base station performs multi-subframe scheduling, a DL DAI value can be preset as that: corresponding to an initial subframe scheduled, DL DAI values of subframes scheduled subsequently are acquired by calculating from a DL DAI of the initial subframe by means of accumulation, and after exceeding a preset scheduling window, a recalculation is made.
It should be noted that, here the examples with regard to the way of the base station side and the UE pre-appointing the multi-subframe scheduling mode and scheduling parameters are not exhaustive examples, the skilled in the art can be inspired to acquire more ways for setting the scheduling mode and scheduling parameters according to the examples in the embodiments of the present document, but all these are to schedule a plurality of uplink subframes or downlink subframes at a time through a piece of DCI based on the present document, which belongs to the protection scope of the present document.
In the step 101, the UE acquiring the multi-subframe scheduling mode and scheduling parameters is: the base station sending the multi-subframe scheduling mode and scheduling parameters to the UE in advance through upper layer signaling, that is, the base station side sends the set multi-subframe scheduling mode and scheduling parameters to the UE through the upper layer signaling when the base station side triggers a plurality of subframes through the DCI. The way for setting the multi-subframe scheduling mode and scheduling parameters is identical with the way for the base station side and the UE pre-appointing the multi-subframe scheduling mode and scheduling parameters, but here it is set at the base station side, which will not be repeated here.
In the step 101, the UE acquiring the multi-subframe scheduling mode and scheduling parameters is: the base station side indicating through the DCI, parameters of the DCI itself such as an MSC, DAI and TBS and so on all can be the scheduling parameters; moreover, a plurality of bits can be reserved in advance in the DCI so as to indicate whether it is multi-subframe scheduling, or the number of subframes scheduled in continuous multi-subframe scheduling, or subframe intervals of a plurality of subframes scheduled in discontinuous multi-subframe scheduling and the total number of subframes scheduled, or whether different types of subframes in the multi-subframe scheduling are allowed, or selecting scheduled subframes based on a transmission mode and so on. The examples here are not exhaustive examples, and the skilled in the art can be inspired to acquire more scheduling mode and scheduling parameters according to the above examples.
It should be noted that, in the embodiments of the present document, the implementation of the specific way for the UE acquiring the multi-subframe scheduling mode and scheduling parameters can include one, or any two, or a combination of three of the following: the base station side and the UE making an appointment in advance, or the base station side sending to the UE in advance through the upper layer signaling, or the base station side indicating through the DCI. Correspondingly, which mode for the parameter will be adopted is not limited in the present document, and the skilled in the art can easily select and determine according to the practical situation.
