Description

Uplink resource allocation method, evolved base station and user equipment, and communication system

technical field

The present invention relates to the communication field, in particular to an uplink resource allocation method, an evolved base station, user equipment and a communication system.

Background technique

In the long-term evolution LTE technology, the scheduling unit is a subframe, that is, 1 millisecond. The subframe has two structures: ordinary subframe and special subframe. The ordinary subframe includes two time slots, each time slot is 0.5 milliseconds, according to For the sequence of each time slot, the two time slots in the normal subframe are respectively called time slot 1 and time slot 2 according to the time sequence; the special subframe includes three special time slots.

In the existing LTE system, there is a type1 resource allocation type for uplink resource allocation. This allocation type makes resource allocation more flexible, and at the same time, compared with the resource allocation type type0, it can also obtain more targeted frequency selection gains. This resource allocation type is also applicable to resource allocation of low-cost terminals.

FIG. 1 is a reference diagram of resource allocation type 1 in which uplink resource allocation exists in an LTE system in the prior art. Under this resource allocation type, when performing uplink/downlink service transmission in each normal subframe, resource block groups (ResourceBlock Group, RBG) are allocated as basic physical resource units, where each RBG consists of multiple physical resources Block (Physical Resource Block, PRB), a PRB in the time domain length is a time slot, in the frequency domain width is 180KHz. FIG. 1 is an example of a system whose bandwidth includes 25 PRBs. According to the type1 resource allocation type, the 25 PRBs of the system bandwidth are divided into 13 RBGs in units of 2 PRBs, and the last RBG contains 1 PRB. Also, the allocated resources are divided into two disjoint clusters. Among them, s0 and s1 are respectively the start position and end position of the resource allocation of cluster1 in units of RBG; s2 and s3 are the start position and end position of resource allocation of cluster2 in units of RBG. It can be seen that for a system with a bandwidth of 25 PRBs, under the uplink resource allocation type type1, the minimum resources allocated are one cluster, one RBG, and two PRBs. For a system with a bandwidth of 100 PRBs, each RBG includes 4 PRBs, and if the resource allocation type of type1 is used for uplink resource allocation, then at least 4 PRBs are allocated for one resource allocation. For data packets that need to be transmitted in machine-type communication, usually less resources are occupied, and resources of 4 PRBs are allocated at a time, which may cause waste of resources.

detailed description

The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

As shown in Figure 2, the LTE system is mainly composed of terminals, base stations and core networks. Among them, base stations can have logical or physical connections according to needs. The network composed of base stations, base stations and terminals is called radio access network (RAN), which is responsible for access layer affairs, such as management of wireless resources; uplink and downlink Wireless resources are scheduled by the base station in the way of shared channels. The base station is connected to the core network node (CN), and the core network is responsible for the non-access layer affairs. The terminal is also the user equipment, which refers to a device that can communicate with the network, such as a mobile phone or a laptop, and each terminal is usually only connected to one base station of the network in the uplink direction. In the LTE system, the base station is often called Evolved base station eNodeB.

In the LTE system, the method for the evolved base station (eNodeB) to allocate RBG to any terminal it manages according to the type1 type is as follows: the eNodeB sends a channel quality indicator (CQI) information to the terminal, according to the resource allocation algorithm stipulated in the protocol The RBG allocation of time slot 1 and time slot 2 is performed on the terminal; the eNodeB notifies the terminal of the RBG allocation result through downlink control information (Downlink Control Information, DCI), and the terminal performs uplink and downlink service data reception and communication at the designated RBG position according to the DCI. send.

FIG. 3 is a flow chart of an embodiment of an uplink resource allocation method proposed based on the system shown in FIG. 2 . This embodiment is described with an evolved base station as an execution subject.

As shown in Figure 3, the uplink resource allocation method includes:

Step S301, generating resource allocation information according to the data communication type of the user equipment;

Specifically, the evolved base station uses the channel quality indication information CQI uploaded by the UE as reference data for resource allocation according to whether the user equipment needs to perform MTC or not, and may also refer to other data to generate resource allocation information.

Step S302, sending resource allocation information to the user equipment in the physical downlink control channel;

Specifically, resource allocation information for a UE or a group of UEs is included in the downlink control information DCI. The eNodeB writes the RBG allocation result in the resource allocation field as resource allocation information in the DCI, that is, in the resource allocation field, and sends the DCI to the user equipment through the physical downlink control channel PDCCH. The user equipment determines the resources allocated to the user equipment according to the resource allocation domain;

The resource allocation field includes the number indication field bit of the resource block group allocated to one or a group of user equipment, and in the resource block group allocated to the one user equipment, the resource block group allocated to the user equipment The indication information field bit of at least one resource block of .

In addition, the eNodeB may also send indication information when sending the resource allocation information, or before sending the resource allocation information, to inform the UE according to which rule to determine the resource blocks allocated to itself from the resource allocation field. For example, it is determined whether to use the traditional type1 or the indication rule given in the embodiment of the present invention.

Alternatively, it is agreed that as long as the transmission data is machine type communication data, the own resource block will be determined according to the rules given in the embodiment of the present invention.

Fig. 4 is based on the system shown in Fig. 2, a proposed uplink resource allocation method performed on the user equipment side, as can be seen from Fig. 4, the method includes:

Step S401, receiving resource allocation information;

Specifically, the UE receives the downlink control information DCI transmitted in the PDCCH sent by the eNodeB, and the DCI information includes resource allocation information, and the resource allocation information includes a resource allocation field of resources allocated to the local user equipment.

Wherein, the resource allocation field includes the number indication field bit of the resource block group allocated to the local user equipment, and in the resource block group allocated to the local user equipment, the resource block group allocated to the user equipment An indication information field bit of at least one resource block of the device.

Specifically, the number of physical resource blocks included in different bandwidths is different, and the number of physical resource blocks included in each resource block group is also different. For example, a 10MHz system bandwidth includes 50 RBs, which are divided into 17 RBGs, where the first 16 RBGs each include 3 RBs, and the last RBG includes only 2 RBs.

However, for a system with a bandwidth of 20 MHz, 100 PRBs are included, and each RBG includes 4 PRBs.

Therefore, each RBG should have a corresponding number, occupying several bits in the resource allocation field for distinction. In each RBG, at least one resource block allocated to the user equipment is also indicated through the bit of the indication information field.

Step S402, determining resources allocated to the local user equipment according to the resource allocation field;

Specifically, the user equipment decodes the indication information of different field bits in the resource allocation field in the resource allocation field according to the pre-specified decoding format, and determines the resource block group allocated to the user equipment, its position in the system bandwidth, and a Among the specific RBGs, which one or several PRBs are allocated to the user equipment, so as to determine the resources occupied by the user equipment when performing service transmission.

In addition, the UE may also receive the indication information sent by the eNodeB before or at the same time as sending the resource allocation information, and obtain the rules for determining the resource blocks allocated by the base station to the local UE from the resource allocation field according to the indication information. For example, it is determined according to the traditional type1 or the rules given in the embodiments of the present invention.

Fig. 5 is a reference diagram of an embodiment of resource allocation in the uplink resource allocation method provided by the embodiment of the present invention.

In the embodiment shown in FIG. 5 , the system bandwidth is 100 PRBs, and one RBG includes 4 PRBs, which can be divided into 25 RBGs, numbered 0 to 24.

Among the above resources, the specific PRB allocated to a certain UE can be indicated in the form of a bitmap through the indication information field bits in the resource allocation field of the DCI. The value of different bits in the indication information field is used to distinguish whether the resource block corresponding to the bit is allocated to the corresponding user equipment.

For example, in the embodiment shown in FIG. 5, two RBGs numbered s0=1 and S2=23 are allocated to a user terminal, and, among the RBGs of S0=1, the first and third PRBs is allocated to user equipment A, and the second and fourth PRBs may be allocated to other user equipments.

For example, if a cluster is used to allocate N PRBs, and the number of RBGs is P, then a bitmap of N bits can be used to indicate the RBGs identified by s0 and s1 and the allocation of N PRBs in the PRBs contained in one or more subsequent RBGs ,by A bit indicates the RBG number assigned to a user terminal, Indicates rounding up.

In the example shown in FIG. 5 , S0=00001 and S2=10111 represent the cluster allocated to the user equipment, and 1010 represents that the first and third PRBs in s0 are allocated to the user equipment A.

In S2, 0110 indicates that the second and third PRBs are allocated to user equipment A.

The user equipment can acquire resources according to field bits in the resource allocation domain of the DCI.

FIG. 6 is a reference diagram of another resource allocation method with a bandwidth of 50 PRBs. In Figure 6, one RBG only includes 3 PRBs, and the bandwidth only includes 17 RBGs, and the last RBG only includes 2 PRBs.

Similarly, a cluster is still used to allocate N PRBs, and the number of RBGs is P, then a bitmap of N bits can be used to indicate the RBGs identified by s0 and s1 and the N PRBs in the PRBs contained in one or more subsequent RBGs. allocation to A bit indicates the RBG number assigned to a user terminal, Indicates rounding up.

Therefore, it is assumed that the clusters allocated to a user equipment A are S0=1 and S2=15 as an example. S0 is coded as 00001 in the DCI resource allocation field, and S2 is coded as S2=01111. The first PRB in S0 is allocated to user equipment A, and the code is 100. The first 2 PRBs in S2 are allocated to user equipment A. Then the code is 110.

The user equipment can obtain resources according to the field bits in the resource allocation field of the DCI and according to a preset decoding rule.

In the foregoing embodiments, s2 and s3 may also be reinterpreted to identify the allocation of RBs in the RBG indicated by s2 and s3.

Through the above two embodiments, the base station can use a bitmap to indicate which PRB is specifically allocated to which user equipment in an RBG. Compared with the prior art, the minimum granularity of resource allocation type 1 can be reduced to one PRB. Instead of an RBG.

However, it should be noted that in the above-mentioned embodiments, the value of the bit of the indication field can be interpreted as required. For example, in the embodiment shown in FIG. 5 , 1010 can be used to represent the The second and fourth PRB.

Fig. 7 is a resource allocation reference diagram of another embodiment of the uplink resource allocation method provided by the embodiment of the present invention. Likewise, this embodiment is described by taking the system bandwidth including 100 PRBs as an example.

In the embodiment shown in FIG. 7 , at least one resource block allocated to a user equipment is indicated by specifying a length in a group of resource blocks allocated to a user equipment.

Similar to the foregoing embodiments, it is also necessary to first distinguish the number of each RBG. For example, S0=0001 and S2=10111 indicate that the RBGs assigned to the user equipment B are the 1st and 23rd RBGs.

Among the RBGs indicated by S1, only the first one is allocated to the user equipment B, and 00 indicates that the length of the PRB allocated to the user equipment B is 1. In the RBG indicated by S2=10111, there are consecutive 1st, 2nd, and 3rd PRBs allocated to user equipment B, and the code is 10, indicating that the length of the PRB allocated to user equipment B is 3. In addition, it is also possible to use a bit to indicate whether the PRB allocated to a user equipment in an RBG is left-aligned or right-aligned. The embodiment shown in FIG. 7 is left-aligned, that is, several consecutive PRBs from the left are allocated for a user device.

If a cluster is allowed to allocate N PRBs, then you can use A bitmap of 4 bits indicates the allocation of N PRBs among the RBGs identified by s0 and s1 and the PRBs included in one or more subsequent RBGs.

After receiving the DCI, the user equipment B distinguishes the resources allocated to itself by the eNodeB according to the indication of the corresponding field bits in the DCI.

Figure 8 is an example where the bandwidth is 50 PRBs, the RBG size is 3, and it is divided into 17 RBGs. Therefore, s1 and s3 use a length value of 2 bits to indicate the RB allocation in the RBG.

If a cluster is allowed to allocate N PRBs, then you can use A bitmap of 4 bits indicates the allocation of N PRBs among the RBGs identified by s0 and s1 and the PRBs included in one or more subsequent RBGs.

For example, it is assumed that the clusters allocated to a user equipment C are S0=1 and S2=15 as an example. S0 is coded as 00001 in the DCI resource allocation field, and S2 is coded as S2=01111. In S0, only the first PRB is allocated to user equipment A, and the code is 00, indicating that only the first PRB is allocated to user equipment C. The 3 PRBs in S2 are all allocated to user equipment C, so the encoding is 10.

In addition, it is also possible to use a bit to indicate whether the PRB allocated to a user equipment in an RBG is left-aligned or right-aligned. The embodiment shown in FIG. 8 is left-aligned, that is, several consecutive PRBs from the left are allocated for a user device.

The user equipment can obtain resources according to the field bits in the resource allocation field of the DCI and according to a preset decoding rule.

In the foregoing embodiments, of course, s2 and s3 may also be reinterpreted to identify the allocation of RBs in the RBG indicated by s2 and s3.

Through the above two embodiments, the base station can use the length indication method to indicate which PRB is specifically allocated to which user equipment in an RBG. Compared with the prior art, the minimum granularity of resource allocation type1 can be reduced to one PRB , rather than an RBG.
