The embodiment of the present application is described with reference to the attached drawing in the embodiment of the present application.
Refer to Fig. 1, Fig. 1 is a kind of configuration diagram of resource control system provided by the embodiments of the present application, the resource Control system includes user equipment and base station, and user equipment can refer to provide to the voice of user and/or setting for data connection It is standby, the computing device of laptop computer or desktop computer etc. can also be connected to, or it can be such as a The autonomous device of personal digital assistant (Personal Digital Assistant, PDA) etc..User equipment can also be known as System, subscriber unit, subscriber station, movement station, mobile station, distant station, access point, remote terminal, access terminal, user terminal, use Family is acted on behalf of or user apparatus.Base station can be access point, node B, evolved node (Environment Bureau, eNB) or 5G base stations (Next generation base station, gNB), refer in the air on interface by one or more sectors and nothing Equipment in the access network that line terminal communicates.By the way that the air interface frame received is converted to IP packets, base station can Internet Protocol net can be included as the router between the remainder of wireless terminal and access network, access network Network.Base station can also coordinate the management of the attribute of air interface.
Refer to Fig. 2, Fig. 2 is a kind of flow diagram of resource control method provided by the embodiments of the present application, this method Including but not limited to following steps：
S201, it is described when base station needs to send data to user equipment or receive the data of the user equipment transmission Base station is detected channel.Channel detection process is as follows：
First, channel status is being detected according to the first granularity, the first granularity is 16us+M*9us, if channel is in sky Not busy state, then take random number N between 0~q, and wherein q is contention window value.Then, channel shape is detected according to the second granularity State, the second granularity are 9us.If channel is in idle condition, when N is kept to 0, expression can start to take letter at this time N-1. Road.If channel is in busy state, channel status is detected again according to the first granularity, if channel is in idle condition, with Machine number N subtracts 1 again, and recovers to detect channel with the second granularity, and and so on.When random number N is kept to 0, representing should Channel is can seizure condition.Meanwhile a maximum channel holding time is given, must after maximum channel holding time terminates It must stop busy channel immediately.And need to re-start Channel Detection, so as to busy channel again.
Wherein, channel can be channel where the corresponding whole carrier frequency of a cell in bandwidth or this The channel in a part of bandwidth (Bandwidth Part, BWP) in the corresponding whole carrier frequency of cell.When base station is to user equipment When configuring the cell, base station can send the 3rd control information to user equipment, and the 3rd control information includes the whole of the cell The bandwidth of carrier frequency and corresponding subcarrier spacing；When base station is to BWP on the user device configuration cell, base station can also be to User equipment sends the 3rd control information, and the 3rd control information includes the bandwidth of the BWP and corresponding subcarrier spacing.3rd Control information can be radio resource control signaling (Radio Resource Control, RRC).
S202, the base station when detect the channel be in can seizure condition when, to the user equipment send first Control information, time-domain resource and frequency domain resource of first control information including distributing to the user equipment, described first Control information is used to indicate that the user equipment receives what the base station was sent in the time-domain resource and the frequency domain resource The data send the data to the base station.
In the specific implementation, the first control information can be Downlink Control Information (Downlink Control Information, DCI).The time-domain resource includes subcarrier spacing and/or time resource number, and time resource number includes Symbolic number and/or time slot (slot) number.Frequency domain resource includes of subcarrier spacing and resource block (Resource Block, RB) Number.
For example, base station can distribute to the first subcarrier spacing of user equipment or the second subcarrier spacing, the first subcarrier Interval can be 15KHz, and 1ms is 1 slot, includes 14 symbols；And if the second subcarrier spacing is 30KHz, 1ms 2 A slot, each slot include 14 symbols.One or more slot of instruction user equipment scheduling at the same time, or one or more words Symbol.Wherein, subcarrier spacing is bigger, and the length of time slot and symbol is shorter；Subcarrier spacing is smaller, and the length of time slot and symbol is got over It is long.
Further, base station can distribute different subcarrier spacings and/or resource to the user equipment of different business Number.For example, for highly reliable low time delay (Ultra-Reliable and Low Latency Communications, URLLC) The user equipment of business, delay requirement is high, and the sending time generally required is very short, can give the user equipment of this kind of type of service The distribution time-domain resource that subcarrier spacing is big, corresponding slot and symbol are short.Even if data can only be opened on symbol 0 or symbol 7 Originate and send, but due to reducing the length of slot and symbol so that listen to channel be in can seizure condition at the time of with symbol Time interval number between 0 or symbol 7 diminishes, so as to reduce the stand-by period for sending data, reduces time domain.And for enhancing Mobile broadband (enhanced Mobile BroadBand, eMBB) business user equipment, data packet is big, it is desirable to transmission Time is longer.Can give small, corresponding slot and the symbol length of user equipment distribution subcarrier spacing of this kind of type of service when Domain resource.Because data packet is greatly, it is necessary to which longer sending time, using larger scheduling time granularity, and then reduces The expense of DCI signalings.
Optionally, first control information further includes signaling period, and the signaling period is used to indicate that the user sets The standby time for monitoring first control information next time or repeatedly, wherein, the signaling period include subcarrier spacing and/or Time resource number, time resource number are slot and/or symbol numbers.It can indicate to use by following several optional modes Family equipment dynamic adjustment signaling period：
The first optional mode, the signaling period in the first control information can be believed with monitoring first control for the first time The cycle phase of breath is same.For example, monitor for the first time the subcarrier spacing that uses of the first control information for 15KHz and slot numbers (or Symbolic number) it is M, then the subcarrier used for indicating to monitor first control information in the first control information next time between Every being similarly 15KHz, slot numbers (or symbolic number) are M, and M is the positive integer more than or equal to 1.
Second of optional mode, signaling period in the first control information can be relative to monitoring described first for the first time The cycle of control information becomes larger.For example, it is 30KHz to monitor the subcarrier spacing that the first control information uses for the first time, and Slot numbers (or symbolic number) are M, then indicate to monitor the use of first control information next time in the first control information Subcarrier spacing be similarly 30KHz, slot numbers (or symbolic number) are N, wherein, N is more than M, or in the first control information Indicate the length that the subcarrier spacing used for monitoring first control information next time is 15KHz, slot and symbol, Indicate that slot numbers (or symbolic number) are N at the same time, wherein, N is more than M, and this mode is suitable for eMBB user, M and N be more than etc. In 1 positive integer.
The third optional mode, signaling period in the first control information can be relative to monitoring first control for the first time The cycle of information processed diminishes.For example, the subcarrier spacing that the first control information of monitoring uses for the first time is 15KHz, and slot Number (or symbolic number) is M, then indicates to monitor the son used of first control information next time in the first control information Carrier wave interval is similarly 15KHz, and slot numbers (or symbolic number) are N, wherein, N is less than M, or is indicated in the first control information The subcarrier spacing used for monitoring first control information next time is 30KHz, and the length of slot and symbol shortens, at the same time Indicate that slot numbers (or symbolic number) are N, wherein, N is less than M, and this mode is suitable for URLLC user, and M and N are more than or equal to 1 Positive integer.
Optionally, first control is sent on first down control channel of the base station in Channel holding time Information, first control information is interior to include time-domain resource and signaling period.And time-domain resource include subcarrier spacing and/or Time resource number；Signaling period also includes subcarrier spacing and/or time resource number.In Channel holding time it is follow-up under The control signaling sent in row control channel does not include signaling period, so that under informing user equipment in the Channel holding time Once or later repeatedly according to the signaling week indicated in first control information sent on first down control channel Phase monitors DCI signalings.The time-domain resource that the control signaling sent in Channel holding time on follow-up down control channel includes In only include time resource number, not comprising subcarrier spacing, so as to inform that user equipment is next in the Channel holding time Time resource number in the secondary or later time-domain resource repeatedly received in DCI signalings is with first down control channel Subcarrier spacing in first control information sent in the time-domain resource of instruction obtains the length of single time resource. So as to save the expense of DCI signalings.
Alternatively, the base station sends described first on multiple down control channels in the Channel holding time Control information, according to customer service type and the real-time change of portfolio, is adjusted using different resource control modes every time Degree.
Wherein, down control channel can be Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) or enhanced Physical Downlink Control Channel (Enhanced Physical Downlink Control Channel, ePDCCH).
For example, due to being used to send Physical Downlink Shared Channel (Physical Downlink Shared before Channel, PDSCH) the length of Channel holding time be all integer millisecond (ms), and shape can be taken by detecting that channel is in The time of state is not fixed, in fact it could happen that among 1ms, it is thus possible to which causing last subframe, some is accounted for positioned at channel With in the time.DCI signalings indicate that last subframe takes several symbols in traditional LTE.And exist in the embodiment of the present application This Channel holding time terminate or this data sending complete before last first control information in, it is necessary to refer to again Show the follow-up cycle for monitoring the first control information.
Further, if this Channel holding time terminates, but data are not sent completely also, illustrate needs again into Row Channel Detection, to obtain Channel holding time, the first follow-up control information is that possible send at any time again, therefore base station can To be shortened with the cycle that the first control information of follow-up monitoring is configured in the first control information of last in Channel holding time. If at the end of this Channel holding time or before terminating, data sending is completed, then last first control information can be with The cycle of configuration the first control information of follow-up monitoring is elongated.
Optionally, the subcarrier spacing in the time-domain resource and/or the bit information of the time resource number It is used to refer to the subcarrier spacing in the signaling period and/or the time resource number at the same time.
For example, in the case that subcarrier spacing in time resource is identical with the subcarrier spacing in signaling period, such as Fruit scheduling time length is 1 slot, then the time for monitoring DCI next time is beginning after 1 slot.If scheduling time Length is M slot, then the time for monitoring DCI next time is beginning after M slot.If scheduling time length is N number of Slot, the then time for monitoring DCI next time are beginning after N number of slot.
In the embodiment of the present application, when base station needs to send data to user equipment or receives what the user equipment was sent During data, base station is first detected channel；When detect the channel be in can seizure condition when, then to the user Equipment sends the first control information, and first control information includes the time-domain resource for distributing to the user equipment and frequency domain money Source, user equipment receive the base station transmission after receiving the first control information in the time-domain resource and the frequency domain resource The data or send the data to the base station.By the instruction cycle for dynamically changing time-domain resource and frequency domain resource With instruction granularity, ensure efficiently using for Channel holding time, while reduce DCI signaling consumptions, reduce user equipment and monitor DCI The power consumption that signaling is brought.
Fig. 3 is referred to, Fig. 3 is a kind of flow diagram for resource control method that another embodiment of the application provides, should Method includes but not limited to following steps：
S301, it is described when base station needs to send data to user equipment or receive the data of the user equipment transmission Base station is detected channel.
Wherein, channel can be channel where the corresponding whole carrier frequency of a cell in bandwidth or this The channel in a part of bandwidth (Bandwidth Part, BWP) in the corresponding whole carrier frequency of cell.When base station is to user equipment When configuring the cell, base station sends the 3rd control information to user equipment, and the 3rd control information includes the whole carrier frequency of the cell Bandwidth and corresponding subcarrier spacing；When base station is to BWP on the user device configuration cell, base station can also be to user Equipment sends the 3rd control information, and the 3rd control information includes the bandwidth of the BWP and corresponding subcarrier spacing.3rd control Information can be radio resource control signaling (Radio Resource Control, RRC).
S302, base station send the second control information to the user equipment, and second control information is used to indicate described User equipment monitors the time of first control information.Wherein, second control information includes subcarrier spacing, sends institute State the second control information and monitor the time interval between first control information for the first time and monitor first control At least one of in the cycle of information.
In the specific implementation, when base station needs to send data to user equipment or receives the data of the user equipment transmission When, base station proceeds by Channel Detection or base station determines that distance detects that channel is in and time of seizure condition can be less than some During duration, base station sends the second control information to the user equipment, the new monitoring PDCCH's or ePDCCH of notifying user equipment Time and/or cycle.When base station needs to send data to user equipment or receive the data of the user equipment transmission, due to Base station may detect that channel is at any time can seizure condition, then and data may be sent at any time, in order to reduce the stand-by period, because This needs to use larger subcarrier spacing, corresponding to reduce slot and symbol lengths.Since slot and symbol lengths reduce, make Must detect channel be in can seizure condition at the time of and the time interval between symbol 0 or symbol 7 diminish.So as to ensure channel Holding time efficiently uses.For example, the detailed process of Channel Detection is as follows:
First, channel status is being detected according to the first granularity, the first granularity is 16us+M*9us, if channel is in sky Not busy state, then take random number N between 0~q, and wherein q is contention window value.Then channel shape is detected according to the second granularity State, the second granularity are 9us.If channel is in idle condition, when N is kept to 0, expression can start to take letter at this time N-1. Road.If channel is in busy state, channel status is detected again according to the first granularity, if channel is in idle condition, with Machine number N subtracts 1 again, and recovers to detect channel with the second granularity, and and so on.When random number N is kept to some threshold value M When, the time and/or cycle of the new monitoring PDCCH or ePDCCH of notifying user equipment.
Wherein, second control information is specific for system information (system Information), the user equipment Radio resource control messages (RRC of UE specific), public Downlink Control Information (DCI of Group Common) with At least one of and in the specific Downlink Control Information of user equipment (DCI of UE specific).
Wherein, second control information can include subcarrier spacing, send second control information and first time Monitor the time interval between first control information and at least one in the cycle for monitoring first control information. Wherein, the time interval for sending second control information and monitoring for the first time between first control information can be the time Resource number, time resource number are slot and/or symbol numbers；The cycle for monitoring first control information provides comprising the time Source number, time resource number are slot and/or symbol numbers.By subcarrier spacing, the time of the second control information is sent, And the time interval, user equipment can obtain the time for monitoring first control information for the first time.Pass through for the first time Monitor the time of first control information and monitor the cycle of first control information, you can know the follow-up control of monitoring first The time of information processed.For example, the subcarrier spacing included in the second control information is 15KHz, then each slot length is 1ms, Include 14 symbols.And if the second control information is sent in slot#0, and the time interval is 1 slot, then first First sign-on that the secondary time for monitoring the first control information is slot#1.If monitor the cycle of first control information For 7 symbols, then time for subsequently monitoring the first control information is the 8th symbol of slot#1, first symbol of slot#2, The 8th symbol ... of slot#2 so on, the signaling period information until sending renewal in the first control information.
It should be noted that when the son used in the subcarrier spacing and the 3rd control information used in the second control information When carrier wave interval is the same, subcarrier spacing information can not be included in the second control information, but including sending second control Information and the cycle for monitoring the time interval and monitoring first control information between first control information for the first time, User terminal acquiescence uses the subcarrier spacing in the 3rd control information, passes through second control in second control information Information processed and the week for monitoring the time interval and monitoring first control information between first control information for the first time Phase also can know that the time and/or cycle for next time or repeatedly monitoring the first control information, so that saving signaling expense.
S303, base station when detect the channel be in can seizure condition when, to the user equipment send first control Information, first control information include the time-domain resource and frequency domain resource for distributing to the user equipment, first control Information is used to indicate that the user equipment is received in the time-domain resource and the frequency domain resource described in the base station transmission Data send the data to the base station.
In the specific implementation, the first control information can be Downlink Control Information.The time-domain resource includes subcarrier spacing And/or time resource number, time resource number include symbolic number and/or time slot (slot) number.Frequency domain resource includes subcarrier Interval and/or the number of resource block (Resource Block, RB).Subcarrier spacing in first control information can be with second The subcarrier spacing of subcarrier in control information is identical, can not also be same.
It should be noted that when the subcarrier spacing and the subcarrier of second control information of first control information When being spaced identical, first control information does not include the subcarrier spacing but writes from memory including time resource number, user terminal Recognize using the subcarrier spacing in the second control information, also be can know that down by time resource number in first control information One or many times for monitoring the first control information and/or the length of cycle or time-domain resource, so that saving signaling expense.
For example, base station can distribute to the first subcarrier spacing of user equipment or the second subcarrier spacing, the first subcarrier Interval can be 15KHz, and 1ms is 1 slot, includes 14 symbols；And the second subcarrier spacing is 30KHz, 1ms is 2 Slot, each slot include 14 symbols.One or more slot of instruction user equipment scheduling at the same time, or one or more characters. Wherein, subcarrier spacing is bigger, and the length of time slot and symbol is shorter；Subcarrier spacing is smaller, and the length of time slot and symbol is longer.
Further, base station can distribute different subcarrier spacings and/or resource to the user equipment of different business Number.For example, for highly reliable low time delay (Ultra-Reliable and Low Latency Communications, URLLC) The user equipment of business, delay requirement is high, and the sending time generally required is very short, can give the user equipment of this kind of type of service The distribution time-domain resource that subcarrier spacing is big, corresponding slot and symbol are short.Even if data can only be opened on symbol 0 or symbol 7 Originate and send, but due to reducing the length of slot and symbol so that listen to channel be in can seizure condition at the time of with symbol Time interval number between 0 or symbol 7 diminishes, so as to reduce the stand-by period for sending data, reduces time delay.And for increasing The user equipment of strong mobile broadband (enhanced Mobile BroadBand, eMBB) business, data packet are big, it is desirable to send Time it is longer.Small, corresponding slot and the symbol length of user equipment distribution subcarrier spacing of this kind of type of service can be given Time-domain resource.Because data packet is greatly, it is necessary to which longer sending time, using larger scheduling time granularity, and then is reduced The expenses of DCI signalings.
Optionally, first control information further includes signaling period, and the signaling period is used to indicate that the user sets The standby time for monitoring first control information next time or repeatedly, wherein, the signaling period include subcarrier spacing and/or Time resource number, time resource number include symbolic number and/or time slot (slot) number.Following several optional sides can be passed through Formula instruction user equipment dynamic adjustment signaling period.
The first optional mode, the signaling period in the first control information with monitoring first control information for the first time Cycle phase is same, i.e. the signaling period provided in the first control information and the first control information of monitoring provided in the second control information Cycle phase it is same.For example, the first control information of monitoring provided in the second control information monitors the first control information for the first time The subcarrier spacing used is that 15KHz and slot numbers (or symbolic number) are M, then is indicated in the first control information next The secondary subcarrier spacing used for monitoring first control information is similarly 15KHz, and slot numbers (or symbolic number) are M.Need Illustrate, if the signaling period indicated in the first control information and the control letter of monitoring first indicated in the second control information The cycle phase of breath at the same time, can not include the signaling period in the first control information, then user terminal acquiescence is continuing with second The cycle of the first control information of monitoring provided in control information.
Second of optional mode, signaling period in the first control information relative to monitoring first control for the first time The cycle of information becomes larger, i.e. the signaling period provided in the first control information is controlled than the monitoring first provided in the second control information The cycle of information processed is big.For example, the first control information of monitoring provided in the second control information monitors the first control for the first time The subcarrier spacing that information processed uses is 30KHz, and slot numbers (or symbolic number) are M, then is referred in the first control information Showing that monitoring the subcarrier spacing that first control information uses next time is similarly 30KHz, slot numbers (or symbolic number) are N, Wherein, N is more than M.Alternatively, indicate to monitor the subcarrier that first control information uses in the first control information next time between The length of 15KHz, slot and symbol are divided into, while indicates that slot numbers (or symbolic number) are N, wherein, N is more than M, this side Formula is suitable for eMBB user.

So as to save the expense of DCI signalings.
Alternatively, the base station sends described first on multiple down control channels in the Channel holding time Control information, according to customer service type and the real-time change of portfolio, is adjusted using different resource control modes every time Degree.Wherein, down control channel can be PDCCH or ePDCCH.
For example, due to being used to send Physical Downlink Shared Channel (Physical Downlink Shared before Channel, PDSCH) the length of Channel holding time be all integer millisecond (ms), and shape can be taken by detecting that channel is in The time of state is not fixed, in fact it could happen that among 1ms, it is thus possible to which causing last subframe, some is accounted for positioned at channel With in the time.DCI signalings indicate that last subframe takes several symbols in traditional LTE.And exist in the embodiment of the present application This Channel holding time terminate or this data sending complete before last first control information in, it is necessary to refer to again Show the follow-up cycle for monitoring the first control information.
Further, if this Channel holding time terminates, but data are not sent completely also, illustrate needs again into Row Channel Detection, to obtain Channel holding time, the first follow-up control information is that possible send at any time again, therefore base station can To be shortened with the cycle that the first control information of follow-up monitoring is configured in the first control information of last in Channel holding time. Certainly, since Channel Detection Time is longer, so base station can first use last first control information instruction user equipment It is elongated to monitor the cycle of the first control information, then in channel detection process, after random number N is kept to M values, reuses second The cycle that control information instruction user equipment subsequently monitors the first control information shortens.If at the end of this Channel holding time Or before terminating, data sending is completed, then last first control information can configure the first control information of follow-up monitoring Cycle is elongated.

For example, in the case that subcarrier spacing in time resource is identical with the subcarrier spacing in signaling period, such as Fruit scheduling time length is 1 slot, then the time for monitoring DCI next time is beginning after 1 slot.If scheduling time Length is M slot, then the time for monitoring DCI next time is beginning after M slot.If scheduling time length is N number of Slot, the then time for monitoring DCI next time are beginning after N number of slot.
S304, the user equipment are received in the time-domain resource and the frequency domain resource described in the base station transmission Data send the data to the base station.
In the embodiment of the present application, when base station needs to send data to user equipment or receives what the user equipment was sent During data, base station is first detected channel；When detect the channel be in can seizure condition when, then to the user Equipment sends the first control information, and first control information includes the time-domain resource for distributing to the user equipment and frequency domain money Source, user equipment receive the base station transmission after receiving the first control information in the time-domain resource and the frequency domain resource The data or send the data to the base station.By the instruction cycle for dynamically changing time-domain resource and frequency domain resource With instruction granularity, ensure efficiently using for Channel holding time, while reduce DCI signaling consumptions, reduce user equipment and monitor DCI The power consumption that signaling is brought.
The above-mentioned method for illustrating the embodiment of the present application, is provided below the device of the embodiment of the present application.
Refer to Fig. 4, Fig. 4 is a kind of structure diagram of resource control provided by the embodiments of the present application, the resource Control device can include processing module 401 and sending module 402, wherein, unit is described in detail as follows.
Processing module 401, for when base station needs to send data to user equipment or receives what the user equipment was sent During data, channel is detected.
Wherein, channel can be channel where the corresponding whole carrier frequency of a cell in bandwidth or this The channel in a part of bandwidth (Bandwidth Part, BWP) in the corresponding whole carrier frequency of cell.When base station is to user equipment When configuring the cell, base station sends the 3rd control information to user equipment, and the 3rd control information includes the whole carrier frequency of the cell Bandwidth and corresponding subcarrier spacing；When base station is to BWP on the user device configuration cell, base station can also be to user Equipment sends the 3rd control information, and the 3rd control information includes the bandwidth of the BWP and corresponding subcarrier spacing.3rd control Information can be radio resource control signaling (Radio Resource Control, RRC).
Optionally, sending module 402, are additionally operable to send the second control information, second control to the user equipment Information is used for the time for indicating that the user equipment monitors first control information.Wherein, second control information includes Subcarrier spacing, send second control information and monitor for the first time time interval between first control information and Monitor at least one in the cycle of first control information.
In the specific implementation, when base station needs to send data to user equipment or receives the data of the user equipment transmission When, base station proceeds by Channel Detection or base station determines that distance detects that channel is in and time of seizure condition can be less than some During duration, base station sends the second control information to the user equipment, the new monitoring PDCCH's or ePDCCH of notifying user equipment Time and/or cycle.When base station needs to send data to user equipment or receive the data of the user equipment transmission, due to Base station may detect that channel is at any time can seizure condition, then and data may be sent at any time, in order to reduce the stand-by period, because This needs to use larger subcarrier spacing, corresponding to reduce slot and symbol lengths.Since slot and symbol lengths reduce, make Must detect channel be in can seizure condition at the time of and the time interval between symbol 0 or symbol 7 diminish.So as to ensure channel Holding time efficiently uses.For example, the detailed process of Channel Detection is as follows:
First, channel status is being detected according to the first granularity, the first granularity is 16us+M*9us, if channel is in sky Not busy state, then take random number N between 0~q, and wherein q is contention window value.Then channel shape is detected according to the second granularity State, the second granularity are 9us.If channel is in idle condition, when N is kept to 0, expression can start to take letter at this time N-1. Road.If channel is in busy state, channel status is detected again according to the first granularity, if channel is in idle condition, with Machine number N subtracts 1 again, and recovers to detect channel with the second granularity, and and so on.When random number N is kept to some threshold value M When, the time and/or cycle of the new monitoring PDCCH or ePDCCH of notifying user equipment.
