For describe in detail to embodiments herein.
Due in the prior art, in order to reduce the expense of control information, increase the handling capacity of communication system, the mode for generalling use semi-persistent scheduling is that Voice traffic data packet distributes running time-frequency resource, specifically, by taking the terminal 110 in Fig. 1 as an example, base station 100 is after activating semi-persistent scheduling, in PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) to terminal 110 send instruction information, instruction terminal 110 is transmitted on which running time-frequency resource, it is illustrated by taking downlink communication as an example, as shown in Figure 2 a, after base station 100 sends instruction information to terminal 110 by PDCCH, when base station 100 needs to send Voice traffic data packet to terminal 110, it then no longer needs to send instruction on PDCCH Information, directly pass through PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) to terminal 110 send Voice traffic data packet, specifically, as shown in Figure 2 b, Voice traffic data packet is sent to terminal 110 by the running time-frequency resource of same position every 20ms, wherein, Voice traffic data packet can also be sent to terminal 110 by the running time-frequency resource of same position every 40ms, after PDCCH sends deactivated instruction information to terminal 110, stop semi-persistent scheduling.
It should be noted that semi-static scheduling cycle here, such as 20ms, 40ms, it is used only for illustrating, is not intended to limit the application.
After introducing eMTC business in existing communication system, it is base station 100 for the first time after dispatching eMTC business data packet that wherein the mode of eMTC business data packet is dispatched in base station 100, one section of running time-frequency resource is occupied to repeat to send the data packet, as shown in Figure 2 c, the running time-frequency resource of filling region is the running time-frequency resource that base station is the distribution of eMTC business data packet.
However since the running time-frequency resource of cell is shared in eMTC business and voice service, when the running time-frequency resource for the eMTC traffic assignments that the running time-frequency resource and base station 100 that the running time-frequency resource for the voice service distribution that base station 100 is terminal 110 is filling region as shown in Figure 2 b are terminal 120 is the running time-frequency resource of filling region as shown in Figure 2 c, running time-frequency resource is caused to clash due to being also assigned to eMTC business data packet in the running time-frequency resource that third 20ms is used for transmission Voice traffic data packet in base station 100.
It since one of data packet is no longer dispatched when running time-frequency resource conflict occurs in base station 100 on the running time-frequency resource clashed in the prior art, therefore will lead to the loss of the performance of uncomfortable degree data packet place business, reduce the experience of user.
To solve the above problems, as shown in figure 3, this application provides a kind of methods of resource allocation, comprising:
Step 300, base station 100 sends the first instruction information to terminal 110, and the first instruction information is used to indicate the first resource distributed by the business data packet of cyclical transmission terminal 110.
In the step 300, when the business data packet of cyclical transmission terminal 110 is the business data packet of Voice traffic data packet or other semi-persistent schedulings, which is used for the semi-persistent scheduling of activated terminals 110.Such as, base station 100 can issue the first instruction information by PDCCH, the first instruction information can be DCI (downlink control information, Downlink Control Information), the resource of the semi-persistent scheduling for terminal distribution is indicated, i.e. terminal carries out periodicity sending or received resource.Specifically, terminal 110 can send business data packet to base station by first resource, the business data packet that base station is sent can also be received by first resource.
In addition, base station 100 can issue the configuration information of semi-persistent scheduling to terminal 110 before above step 300, terminal 110 passes through the period of the available semi-persistent scheduling of the configuration information.For terminal 110 after receiving the configuration information of the semi-persistent scheduling, terminal detects the first instruction information on PDCCH, can activate the semi-persistent scheduling, carry out data and send or receive.The configuration information of semi-persistent scheduling can be RRC (radio resource control, wireless heterogeneous networks) configuration information.
It should be noted that, the business data packet of first terminal transmission can be Voice traffic data packet in the embodiment of the present application, such as VoIP (Voice over Internet Protocol, voice based on Internet Protocol) business data packet, it can also be the business data packet of other cyclical transmissions, base station can strategy based on the allocation of packets resource for being in advance these cyclical transmissions or algorithm can directly be these business data packets distribution resource, without dynamic allocation of resources.Optionally, the business data packet of first terminal transmission is non-eMTC business data packet.
Step 301, when base station 100 includes first resource in the transfer resource that current period is distributed by the business data packet of transmission terminal 120, Secondary resource is distributed for terminal 110, Secondary resource is different transfer resources from first resource.
Such as, as shown in Figure 2 b, assuming that filling resource block base station between lines a and lines b while distributing to 110 transmission services data packet of terminal, distribute to 120 transmission services data packet of terminal, it causes to fill resource block between lines a and lines b and resource contention occurs, base station 100 is again the distribution of terminal 110 the
Two resources, wherein Secondary resource can between lines a and lines b in addition to filling resource block other resource blocks being in idle condition, or the resource block that subsequent time is in idle condition.The application is not limited, as long as not conflicting with the first resource in current period.
Optionally, the business data packet that terminal 120 is transmitted is eMTC business data packet.
Step 302, base station 100 sends second indication information to terminal 110, and second indication information is used to indicate the Secondary resource distributed in current period by the business data packet of transmission terminal 110.
In this application, terminal 110 and terminal 120 are different terminals, and the business of the data packet of terminal 110 and terminal 120 respectively can be different business, or identical business.
As shown in Figure 4, using the business data packet of first terminal transmission as Voice traffic data packet, second terminal transmission business data packet be eMTC business data packet for transmission data packet method be described in detail, when first terminal conflicts with second terminal generation transfer resource, when the data packet that first terminal and second terminal are transmitted is respectively the data packet of other business, business data packet with first terminal transmission is Voice traffic data packet, the business data packet of second terminal transmission is that the method for eMTC business data packet transmission data packet when transfer resource conflict occurs is similar, details are not described herein.
As shown in figure 4, a kind of method for transmitting data packet of the embodiment of the present application, comprising:
Step 400, base station sends RRC signaling to first terminal, includes semi-persistent scheduling configuration information in RRC signaling, includes the information such as the period of semi-persistent scheduling in semi-persistent scheduling configuration information；First terminal receives RRC signaling, obtains semi-persistent scheduling configuration information.
Step 410, base station sends the first instruction information to first terminal, and the first instruction information is used to indicate the first resource distributed by the business data packet of cyclical transmission first terminal；First terminal receives the first instruction information.
The configuration and activation of the semi-persistent scheduling of business data packet between base station and first terminal are realized by step 400 and step 410, such first terminal can utilize semi-persistent resource, i.e. first resource, periodically be transmitted.Same base station also can use the semi-persistent resource, send business data packet to first terminal.
Step 420, first terminal passes through cyclical transmission business data packet between first resource and base station.
By taking the business data packet of first terminal is Voice traffic data packet as an example, week is dispatched in current semi-static
In phase, in the Voice traffic data packet for receiving first terminal, base station sends Voice traffic data packet to first terminal by first resource for base station；When first terminal needs to send Voice traffic data packet to base station, first terminal sends Voice traffic data packet to base station by first resource.
Step 430, when base station has the business data packet of second terminal to need to send or receive the request of second terminal transmission services data packet, resource is distributed for second terminal, and resource allocation information is sent to second terminal, resource allocation information is used to indicate to transmit the transfer resource that the business data packet of second terminal is distributed, second terminal receives resource allocation information, determines and business data packet is transmitted or received on the transfer resource that resource allocation information indicates.
It should be noted that base station, which is based on preconfigured strategy, to distribute continuous transfer resource for second terminal when the business data packet of second terminal is eMTC business data packet.
Step 440, business data packet is transmitted on the transfer resource that resource allocation information indicates or received to second terminal.
Step 450, base station is when it includes first resource that current semi-static, which detects in the resource for second terminal distribution dispatching cycle, Secondary resource is distributed for first terminal, and second indication information is sent to first terminal, second indication information is used to indicate within current semi-static dispatching cycle to transmit the Secondary resource that the business data packet of first terminal is distributed, wherein, Secondary resource is different transfer resources from first resource.
Step 460, after first terminal receives second indication information, business data packet is transmitted or received using Secondary resource in current semi-static dispatching cycle.
Step 470, first terminal continues that business data packet is transmitted or received using first resource in next semi-static scheduling cycle.
Specifically, when the business data packet needs for having first terminal in next cycle continue transmission, if base station is detecting that the instruction information that resource contention and not sending to first terminal deactivates semi-persistent scheduling does not occur for first resource in next cycle, continue in next cycle using first resource transmission services data packet.
When the business data packet needs for having first terminal in next cycle continue transmission, if base station is detecting first resource generation resource contention in next cycle, then base station dynamically distributes new transfer resource again again for first terminal, the transfer resource and the first transfer resource are different transfer resources, then to
First terminal sends the information of transfer resource used by instruction transmission services data packet, the new transmission resources for transmitting or reception business data packet that first terminal is redistributed in next semi-static scheduling cycle using base station.
In addition, base station, which sends third to first terminal, indicates that information, third instruction information are used to indicate the business data packet that stopping uses first resource cyclical transmission first terminal, i.e. stopping semi-persistent scheduling.By taking Voice traffic data packet as an example, third instruction information is to deactivate the instruction information of semi-persistent scheduling, and after base station, which detects, meets the condition for deactivating semi-persistent scheduling, the instruction information for deactivating semi-persistent scheduling is sent to first terminal.Specifically, after base station sends the first instruction information to first terminal in base station to first terminal transmission third instruction information, it can be before distributing Secondary resource for first terminal, it can also be after for first terminal distribution Secondary resource.
When the business data packet needs for having first terminal in next cycle continue transmission, if base station has sent the instruction information for deactivating semi-persistent scheduling to first terminal, then base station activation semi-persistent scheduling can also be first terminal allocation of transmission resources by dynamic dispatching.
It should be noted that, in the method for transmission data packet shown in Fig. 4, there is no inevitable sequencing between step 400~step 420 and step 430, step 440, as long as step 400, step 410, step 420 sequence are constant, the sequence between step 430, step 440 is constant.
It should be noted that the transmission of the business data packet of the business data packet and second terminal of first terminal can be uplink in above embodiments, it is also possible to downlink transfer.That is, the business data packet of first terminal and the business data packet of second terminal can be sent to base station by terminal, terminal can also be sent to by base station.
