Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
The base station adopts a common method that downlink data is sent to the terminal by multiple paths and is sent over the air interface. In addition, with the proposal of ultra-reliable low-latency communication (URLLC) service in 5G, the method of "multiple times/duplication" is increasingly used, that is, the same data packet is transmitted on different links by CA, DC/MC, etc., for example, duplication transmission by Packet Data Convergence Protocol (PDCP) layer, so as to obtain robustness gain of multilink parallel transmission.
However, in the above method, data packets need to be scheduled and resource allocated separately on each link, for example, on DC/MC, each data packet is sent on a different base station, so the air interface resource of each data packet is allocated separately. Meanwhile, fig. 1 shows a downlink L2 architecture after CA configuration, and fig. 2 shows an uplink L2 architecture after CA configuration, and as can be seen from fig. 1 and fig. 2, in a CA scenario, scheduling and resource allocation of a data packet are also performed independently, and each Component Carrier (CC) (member Carrier of CA) corresponds to one HARQ entity no matter uplink or downlink, and each HARQ entity performs resource allocation on each CC independently. Then, when performing duplicate transmission, the resource allocation is performed on each CC separately by sending the duplicate transmitted packet blocks separately. Since resources are separately allocated (a Transport Block (TB) for multiplex transmission is separately allocated to one data packet), no uniform coordination is performed in scheduling and allocating resources, reducing the gain of multiplex transmission.
Therefore, the packet can be copied at the MAC layer. The data packet is copied and transmitted at the MAC layer, the upper link can be simplified by copying at the MAC layer, and multiplexing gain with higher reliability and real-time performance is realized by means of flexible scheduling capability of the MAC layer and multi-channel capability brought by CA.
Based on this, in various embodiments of the present invention, at the MAC layer of the network device, it is determined that a first packet interacting with the terminal needs to be multiplexed for transmission; at the MAC layer, allocating the resource for multiplexing transmission for the first data packet based on the resource pre-allocation information for multiplexing transmission of the terminal; the pre-allocated resource information comprises the times of copying and sending the data packet and the resource information corresponding to each sending.
In the scheme of the embodiment of the invention, because the resource allocation of multiplexing transmission is carried out on the MAC layer, a plurality of transmission resources in one multiplexing TB resource are allocated to the data packet of multiplexing transmission by utilizing the pre-allocated resource information for multiplexing transmission on the MAC layer, thus, one multiplexing TB block can be uniformly coordinated, and the transmission gain of a plurality of physical transmission channels and the compatibility of a system are realized.
When multiplex transmission is performed at the MAC layer, transmission-related processing is performed on each packet alone only at the lower layer (including the physical layer (PHY) layer), and transmission-related processing is not performed on each packet at the upper layer (radio link control (RLC), PDCP).
An embodiment of the present invention provides a resource allocation method, which is applied to a network device, and as shown in fig. 3, the method includes:
step 301: determining that a first data packet interacted with a terminal needs to be multiplexed and transmitted on an MAC layer of the network equipment;
step 302: and allocating the resource for multiplexing transmission for the first data packet based on the resource pre-allocation information for multiplexing transmission of the terminal at the MAC layer.
Here, the pre-allocated resource information includes the number of times of packet replication transmission and resource information corresponding to each transmission.
The multiplexing transmission may also be understood as a duplicate transmission, where duplicate transmission in the duplicate transmission refers to: copying the source data packet to obtain one or more copied data packets; the source packets and/or the copied packets are sent to the recipient. The source packet and the copied packet are identical.
The resource used by each data packet may be at least one Physical Resource Block (PRB) and may also be at least one Resource Element (RE).
In practical applications, the network device may specifically be a base station, such as a next generation node B (gNB).
Data of the MAC layer needs to be transmitted to the PHY layer, and thus, a packet may be referred to as a TB (in order to distinguish from a TB resource, the TB resource is referred to as a TB block in the following description), which is referred to the PHY layer. Specifically, for the MAC protocol entity, the MAC protocol entity performs transmission related processing on a received Service Data Unit (SDU) of the MAC layer to obtain a Protocol Data Unit (PDU) of the MAC layer, and for the PHY layer, the PHY protocol entity receives the PDU transmitted by the MAC protocol entity, which is called TB, and before the PHY layer performs encoding, the TB may be called a codeword (codeword).
In practical application, the network device needs to pre-allocate resources for the multiplexed data packet interacted with the terminal.
Based on this, in an embodiment, the method may further include:
at the MAC layer, determining that a data packet interacted with the terminal needs to start multiplexing transmission;
and at the MAC layer, performing resource pre-allocation of packet multiplexing transmission to obtain the resource pre-allocation information.
In practical application, the QoS of the data packet is the fundamental factor for driving the multiplexing transmission.
Based on this, in an embodiment, the network device may determine that the data packet sent to the terminal needs to initiate multiplexing transmission based on the QoS of the data packet.
In practical application, the network device may determine whether to start multiplexing transmission according to QoS of a data packet and a guarantee requirement for sending the data packet over an air interface. For example, the QoS requirement is high, and if the channel quality is good at this time, the multiplexing transmission may not be started, or may be started; if the channel quality is not good at this point, multiplexed transmission may be initiated to increase the probability of successful transmission of data at one time.
In an embodiment, the pre-allocating resources for performing packet multiplexing transmission includes:
determining at least one resource available to the terminal;
and performing resource pre-allocation of the packet multiplexing transmission by using the determined at least one resource.
In an embodiment, the pre-allocating resources for packet multiplexing transmission by using the determined at least one resource includes:
sequencing at least one resource according to the measured value of the at least one resource to obtain a sequencing result;
and pre-allocating resources for multiplexing and transmitting the data packets by utilizing the sequencing result and combining the data volume to be transmitted.
Here, in actual application, the resource pre-allocation for the terminal to perform packet multiplexing transmission may also be performed in combination with whether CA is started.
Based on this, in an embodiment, when performing resource pre-allocation for packet multiplexing transmission, the method further includes:
judging whether CA needs to be started;
and when the CA is determined to be started, determining the CC of the CA, wherein the obtained resource pre-allocation information also comprises the CC where the corresponding resource is sent each time.
In practical application, for network equipment and a terminal, data transmission is divided into uplink transmission and downlink transmission; wherein, the uplink transmission refers to that the terminal transmits information to the network equipment; the downlink transmission refers to: the network device sends information to the terminal.
When the first data packet is a downlink data packet, that is, when the network device sends the first data packet to the terminal, the allocating, for the first data packet, resources for multiplex transmission based on the resource pre-allocation information that is sent for multiplexing by the terminal includes:
and allocating resources for the first data packet based on the resource pre-allocation information for the terminal multiplexing transmission and available resources.
When the resources are allocated, the available resources of the network equipment are combined, so that the unified scheduling processing between the multiplexing data packets and the non-multiplexing data packets is realized.
Specifically, in an embodiment, the allocating resources for the first data packet based on the resource pre-allocation information and available resources that are sent for multiplexing by the terminal includes:
determining that the resources corresponding to the resource pre-allocation information are in available resources;
and taking the resource corresponding to the resource pre-allocation information as the resource for multiplexing and transmitting the first data packet.
That is to say, when the resource corresponding to the resource pre-allocation information is completely contained in the available resources, the resource corresponding to the resource pre-allocation information is used as the resource for multiplexing and transmitting the first data packet.
When it is determined that part of the resources corresponding to the resource pre-allocation information are in available resources, the part of the resources may be used as resources for multiplexing transmission of the first data packet.
That is, when a part of resources in the resources corresponding to the resource pre-allocation information is included in the available resources, the part of resources is used as resources for multiplexing and transmitting the first data packet.
In this case, since the partial resources are less than the pre-allocated resources, the first packet needs to be subjected to transmission-related processing so as to be multiplexed on the partial resources.
Here, in practical applications, the transmission related processing may be determined as needed, for example, to increase a Modulation and Coding Scheme (MCS) level used by the first packet so as to reduce resources used for multiplexing transmission.
When it is determined that part of the resources corresponding to the resource pre-allocation information are in available resources, the resources corresponding to the resource pre-allocation information may also be used as resources for multiplexing transmission of the first data packet.
At this time, since other resources except the partial resources in the resources corresponding to the resource pre-allocation information are already allocated to send other data packets, at this time, it is necessary to perform sending related processing on other data packets, so as to reduce the resources occupied by the other data packets.
Based on this, in an embodiment, the data packets corresponding to the other resources except the partial resources in the resources corresponding to the resource pre-allocation information are subjected to the transmission related processing, so that the resources corresponding to the resource pre-allocation information can be used as the resources for multiplexing and transmitting the first data packet.
In practical application, the transmission related processing may be determined as needed, for example, increasing the MCS level, decreasing the length of the transmitted MAC PDU, and the like.
When all resources corresponding to the resource pre-allocation information are not in the available resources, namely all the resources are not contained in the available resources, determining a first resource from the used resources; and taking the first resource as a resource for multiplexing transmission of the first data packet.
And the first resource is in the resource corresponding to the resource pre-allocation information.
Here, in actual application, since the first resource is selected from the used resources for multiplex transmission, the transmission related processing may be performed on the packet corresponding to the first resource so as to perform multiplex transmission on the first resource, for example, the MCS level may be increased and the MAC PDU to be transmitted may be decreased. In addition, the first packet may be subjected to transmission related processing, for example, an MCS level may be increased to reduce resources used for multiplexing transmission, so that multiplexing transmission may be performed on the first resources.
When the first data packet is an uplink data packet, that is, when the terminal sends the first data packet to the network device, the allocating, for the first data packet, resources for multiplex transmission based on the resource pre-allocation information that is sent for the terminal in a multiplex manner includes:
and taking the resource corresponding to the resource pre-allocation information multiplexed and transmitted by the terminal as the resource multiplexed and transmitted by the first data packet.
In the resource allocation method provided by the embodiment of the invention, a first data packet interacted with a terminal is determined to be transmitted in a multiplexing way on an MAC layer of network equipment; at the MAC layer, allocating the resource for multiplexing transmission for the first data packet based on the resource pre-allocation information for multiplexing transmission of the terminal; the pre-allocated resource information comprises the times of data packet copy sending and the resource information corresponding to each sending, and because the resource allocation of multiplexing transmission is carried out on the MAC layer, the resource information pre-allocated for multiplexing transmission is utilized on the MAC layer to allocate a plurality of transmission resources in one multiplexed TB resource for the data packet of multiplexing transmission, thus, one multiplexed TB block can be uniformly coordinated, and the sending gain of multiple physical transmission channels and the compatibility of the system are realized.
The present invention will be described in further detail with reference to the following application examples.
In the embodiment of the present application, in the case of multiplexing transmission, the resource allocated to each data packet is at least one Physical Resource Block (PRB), which may be referred to as a PRB block.
First, the multiplexing transmission of the terminal is preprocessed, that is, the resource is pre-allocated.
Whether the packet multiplexing needs to be started is judged in units of data packets (not in units of UE, nor in units of Resource Blocks (RB), but in units of each specific data packet, that is, whether the multiplexing transmission needs to be started is judged for each data packet). In any UE having any characteristic, if there is a single packet to be transmitted by multiplexing, multiplexing is performed on the single packet.
The pretreatment process, as shown in fig. 4, includes:
step 401: starting pretreatment;
here, for downlink transmission (transmission from the base station to the terminal), preprocessing is started after data transmitted from an upper layer is received; for uplink transmission (terminal is sent to base station), the base station side starts preprocessing after receiving Buffer Status Report (BSR) information reported by the terminal.
Here, the preprocessing is also understood as pre-allocation of resources, the purpose of the pre-allocation is to reduce the complexity of one allocation, and the preprocessing includes: and performing resource allocation according to the channel quality of the user and the data quantity required to be transmitted.
In the formal allocation, the resource allocated to a user not only needs to consider the two factors of the channel of the user and the amount of data to be transmitted, but also needs to consider the amount of resources already used by other users with higher priority than the user.
Thus, the formally allocated resources may be reduced or increased in equal proportion to the actual available resources, as compared to the pre-allocated resources.
Step 402: judging whether the data packet needs to start multiplexing transmission or not based on the QoS requirement, if not, executing a step 403, and if so, executing a step 404;
here, in the downlink direction, the base station determines whether the data packet needs to start multiplexing transmission according to the QoS parameter requirement of the data packet.
In the uplink direction, the base station may determine whether multiplexing transmission needs to be started according to the QoS parameter and by combining the priority of a Logical Channel Group (LCG) in the BSR.
Step 403: preprocessing according to a conventional method, and then executing a step 409;
step 404: judging whether CA needs to be started according to the historical air interface channel characteristics of the UE to which the data packet belongs, if so, executing step 405, and if not, executing step 406;
here, the historical channel characteristics of the air interface for the UE to transmit and receive data on the air interface may include: the initial BLock Error rate (BLER), the residual BLER, the probability of retransmission, the number of times of Radio Link Failure (RLF), the average rate of data transmission, the average signal-to-noise Ratio (SNR) of channel measurement, and other parameters of the UE on each channel.
In practical application, when it is determined that CA needs to be started, the CA can be configured according to signaling of RRC.
Here, whether or not CA needs to be activated may be determined based on the number of data that the user needs to transmit, or may be determined based on whether or not extremely high reliability is required (for example, multiple CC links perform duplicate transmission).
Step 405: determining the number of CCs needing to start CA;
here, the RRC entity may configure the CA of the UE to include a plurality of CCs, and start all or part of the CCs as needed.
Step 406: sequencing PRBs available for the UE according to the measurement values of the PRBs;
here, when CA is not started, the PRBs available to the UE are ordered according to the measured values of the PRBs on the carriers; when CA is started, the PRBs available to the UE are ordered according to the PRB measurement values on each CC.
Step 407: allocating the sequenced PRBs to form alternative PRB blocks;
here, a PRB block may consist of several consecutive PRBs.
When combining PRB blocks, estimation is performed according to the amount of data to be transmitted (i.e., the size of a packet to be copied and transmitted).
That is, resource pre-allocation is performed.
Step 408: according to the channel characteristics, the number of times of repeated transmission and the corresponding PRB block to be transmitted each time are given, and then step 409 is executed;
when CA is started, CC information where PRB blocks are located also needs to be given.
Step 409: the current processing flow is ended.
Second, scheduling and resource allocation are performed.
For the downlink data packet, the process of scheduling and resource allocation, as shown in fig. 5, includes:
step 501: a scheduler of the MAC layer triggers scheduling;
step 502: finishing the sequencing of the UE of the system, and performing resource allocation on the UE according to the sequence, namely executing step 503;
here, the ranking index for each user may be calculated according to the delivered scheduling algorithm. On the basis of the traditional sequencing index, the capability synthesis of QoS service requirements is increased, specifically, parameters such as whether multiplexing transmission is needed or not, ultra-short transmission delay in QoS, ultra-high reliability and the like can be included, that is, when the sequencing index is calculated, the parameters are included through a certain mathematical method, such as Lagrange fitting and the like.
Step 503: for a data packet, determining whether multiplexing transmission is required, if so, executing step 505, and if not, executing step 504;
here, the packet is a MAC PDU, and is composed of RB packets. One MAC PDU may carry only one MAC SDU, or may carry multiple MAC SDUs or MAC CEs.
Here, whether the data packet needs to be multiplexed or not can be obtained according to the result of the pre-scheduling.
Step 504: allocating resources on the corresponding carriers in a conventional manner, and then performing step 511;
here, it is not necessary to multiplex transmission, and it can be stated that the data packet is a normal data packet, that is, a data packet without a duplicate transmission requirement.
If the scenario is CA, resources may be allocated on one CC or multiple CCs, and if the scenario is non-CA, the scenario is normal carrier.
And when the resources are allocated, the resources are allocated to the data packet by combining the preprocessed resource allocation result.
Step 505: reading resource allocation information during pre-scheduling;
that is, pre-allocated resource information is read.
Step 506: searching available PRB blocks in available PRB resources according to the size of the pre-allocated PRB blocks;
that is, a valid PRB block is searched for according to a pre-allocated PRB block size.
Step 507: judging whether the effective PRB block is found or not, and performing different operations according to the judgment result;
step 508: when the pre-allocated PRB block is completely available, allocating the PRB block according to the pre-allocated PRB block, and then performing step 511;
step 509: when the pre-allocated PRB block is partially occupied and partially available, adjusting the pre-allocated resources or the allocated resources to obtain PRBs for multiplexing transmission, and then performing step 511;
here, the manner of adjusting the allocated resources may be: PRBs are allocated using pre-allocated PRB blocks by squeezing from allocated PRBs, such as by increasing the MCS level, decreasing the length of the transmitted MAC PDU, and so on.
The way to adjust the pre-allocated resources may be: the MCS level is adjusted up to reduce the requirement on the number of PRBs.
When the PRB blocks are distributed, the PRB blocks among different CCs are preferentially used in a CA scene, and then the PRB blocks in the CCs are used; in a non-CA scenario, one or more PRB blocks are used for the data packet multiplexing transmission, and the number of the PRB blocks used for the data packet multiplexing transmission is also one.
Step 510: when all the pre-allocated PRB blocks are occupied, adjusting the allocated resources to obtain PRBs for multiplexing transmission, and then performing step 511;
that is, when there is no PRB block available that is the same as the pre-scheduled PRB block, in order to ensure transmission of the traffic packet, the allocated PRB resources are compressed, for example, the MCS level is increased, the length of the transmitted MAC PDU is decreased, and so on, so that the copy transmission can be performed using at least one pre-allocated PRB block, or the allocated PRB resources are compressed, and the MCS level used by the multiplexed TB is increased to reduce the requirement for the number of PRBs, so that the copy transmission is implemented.
Step 511: the current processing procedure is ended.
And for the uplink data packet, the base station side performs scheduling by using pre-allocated resources according to the BSR completely to complete the preliminary scheduling of the data packet. The scheduling command is then sent to the UE, which uses these PRB blocks according to the scheduling command of the base station.
As can be seen from the above description, the resource allocation method according to the embodiment of the present invention implements allocation of multiple PRB resource blocks in packet multiplexing.
In addition, the unified scheduling and distribution of resources among CCs and in the CCs are realized; moreover, the compatibility is good, and the 3G, 4G and 5G networks can be compatible. And directly sending each data packet one by one under a 3G or 4G network.
In order to implement the method of the embodiment of the present invention, the present invention further provides a resource allocation apparatus, which is disposed on a network device, and as shown in fig. 6, the apparatus includes:
a determining unit 61, configured to determine, at an MAC layer of the network device, that a first data packet interacted with a terminal needs to be multiplexed and transmitted;
