This is incorporated herein by reference. The present invention relates to the field of wireless communications, and in particular, to an uplink resource allocation method, an evolved base station, a user equipment, and a communication system. Background technique

In the long-term evolution LTE technology, the scheduling unit is one subframe, that is, 1 millisecond. The subframe has two structures: a normal subframe and a special subframe, where the normal subframe includes two slots, each slot is 0.5 milliseconds, according to In the order of each time slot, two time slots in a normal subframe are respectively referred to as time slot one and time slot two according to chronological order; the special subframe includes three special time slots.

In the existing LTE system, there is a type 1 resource allocation type for uplink resource allocation, which makes the resource allocation more flexible, and at the same time, a more targeted frequency selection gain can be obtained with respect to the resource allocation type typeO. This resource allocation type can also be applied to resource allocation of low-cost terminals. FIG. 1 is a reference diagram of a resource allocation type of type1 in which an uplink resource allocation exists in a prior art LTE system. Under the resource allocation type, when performing uplink/downlink traffic transmission in each normal subframe, a resource block group (RBG) is allocated as a basic physical resource unit, where each RBG is composed of multiple physics. A physical resource block (PRB) is composed of a PRB having a length in the time domain and a width of 180 kHz in the frequency domain. Figure 1 is an example of a system with 25 PRBs in bandwidth. According to the type1 resource allocation type, the system bandwidth 25 PRBs are divided into 13 RBGs in units of 2 PRBs, and the last RBG contains 1 PRB. And, the allocated resources are divided into two discrete clusters cluster. Where s0 and s1 are the resource allocation start position and end of the cluster! in RBG, respectively; s2 and S3 are the resource allocation start position and end position of the cluster2 in RBG. It can be seen that for a system with a bandwidth of 25 PRBs, under the uplink resource allocation type typel, the minimum resource allocated is one cluster, one RBG, 2 PRB. For a system with a bandwidth of 100 PRBs, each RBG contains 4 PRBs. If the uplink resource allocation uses the type allocation resource type, then the primary resource allocation is at least 4 PRBs. For the type of communication in the machine type communication, the data packets that need to be transmitted usually occupy less resources and allocate resources of 4 PRBs at a time, which may cause waste of resources.

detailed description

The technical solution of the present invention will be further described in detail below through the accompanying drawings and embodiments. As shown in FIG. 2, the LTE system is mainly composed of a terminal, a base station, and a core network. The base stations may have logical or physical connections as needed. The network consisting of base stations, base stations, and terminals is called a radio access network (RAN), which is responsible for access layer transactions, such as radio resource management; uplink and downlink. The radio resources are scheduled by the base station in a shared channel manner, the base station is connected to the core network node (CN), and the core network is responsible for non-access stratum transactions. A terminal is a user equipment, which refers to a device that can communicate with a network, such as a mobile phone or a laptop computer, 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.

The method for allocating RBGs for any one of the terminals managed by the evolved base station (eNodeB) according to the type 1 type in the LTE system is: eNodeB The terminal that sends the channel quality indicator (CQI) information, according to the resource allocation algorithm specified by the protocol Performing RBG allocation for slot 1 and slot 2 for the terminal; eNodeB passes RBG allocation result through downlink control information (Downlink Control Information, DCI) informs the terminal that the terminal is specified according to DCI

The RBG location performs reception and transmission of uplink and downlink service data.

FIG. 3 is a flowchart of an embodiment of an uplink resource allocation method according to the system shown in FIG. 2. This embodiment is described by using an evolved base station as an execution subject.

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

Step S301: Generate 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 the reference data of the allocated resource according to whether the user equipment is to perform the machine type communication MTC. Generate resource allocation information by referring to other data.

Step S302: Send resource allocation information to the user equipment in the physical downlink control channel. Specifically, the downlink control information DCI includes resource allocation information for one UE or one group of UEs. The eNodeB writes the RBG allocation result in the resource allocation field of the resource allocation information in the DCI, that is, the resource allocation domain, and passes the DCI through the physical downlink control channel.

The PDCCH is sent to the user equipment. The user equipment determines, according to the resource allocation domain, a resource allocated to the user equipment;

In the resource allocation field, a number indication field bit of a resource block group assigned to one or a group of user equipments, and among the resource block groups assigned to the one user equipment, are allocated to the user equipment The indicator field of at least one resource block.

In addition, the eNodeB may also send indication information at the same time as transmitting the resource allocation information or before transmitting the resource allocation information, and inform the UE according to what rules the resource blocks allocated to itself are determined from the resource allocation domain. For example, it is determined in the conventional typel or in 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 resource blocks are determined according to the rules given by the embodiment of the present invention.

FIG. 4 is a schematic diagram of an uplink resource allocation method performed on the user equipment side, and the method includes: Step S401, receiving resource allocation information;

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

The resource allocation field includes a number indication field bit of the resource block group allocated to the local user equipment, and is allocated to the user in the resource block group allocated to the local user equipment. The 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 10 MHz system bandwidth, consisting of 50 RBs, is divided into 17 RBGs, where the first 16 RBGs each include 3 RBs, and the last RBG contains only 2 RBs.

For a system with a bandwidth of 20 MHz, including 100 PRBs, each RBG contains 4 PRBs. Therefore, each RBG should have a corresponding number, occupying several bits in the resource allocation domain to distinguish. In each RBG, at least one resource block to which the user equipment is allocated is also indicated by an indication information field bit.

Step S402, determining resources allocated to the local user equipment according to the resource allocation domain. Specifically, the user equipment decodes indication information of different field bits in the resource allocation domain in the resource allocation domain according to a predetermined decoding format, and determines allocation. The resource block group of the user equipment, the location in the system bandwidth, and the specific PRB, which one or which PRBs are allocated to the user equipment, in order to determine the resources occupied by the user equipment when performing service transmission .

In addition, the UE may also receive the indication information that is sent by the eNodeB before or during the transmission of the resource allocation information, and obtain the rule for determining the resource block allocated by the base station to the local UE from the resource allocation domain according to the indication information. For example, it is determined according to the conventional typel or the rules given in the embodiment of the present invention. Reference map.

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

In the foregoing resources, the specific PRB allocated to a certain UE may be indicated in a bitmap bitmap manner by using the indication information field bit in the resource allocation field in the DCI. Whether the resource block corresponding to the bit is allocated to the corresponding user equipment is distinguished by a value of a different bit in the indication information field bit.

For example, in the embodiment shown in FIG. 5, two RBGs numbered s0=l and S2=23 are assigned to one user terminal, and, in the RBG of S0=1, the first and third PRBs It is assigned to User Equipment A, and the 2nd and 4th PRBs may be assigned to other User Equipments.

For example, if a number of RBGs are allocated by a cluster, and the number of RBGs is P, then the N bits of the bit may be used to indicate the allocation of the RBGs identified by the sO and the si and the N PRBs of the PRBs included in the subsequent one or more RBGs. , with "log ₂ P, bit indications assigned to a user terminal

RBG number, ", indicates rounding up.

In the example shown in Fig. 5, clusters assigned to user equipments are represented by S0 = 00001 and S2 = 10111, and 1010 indicates that the first and third PRBs are allocated to user equipment A in s0.

In S2, the 0th and the 3rd PRBs assigned to the user equipment A are indicated. The user equipment can obtain resources according to field bits in the resource allocation domain of the DCI.

Figure 6 shows a reference diagram of another resource allocation method with a bandwidth of 50 PRBs. In Figure 6, an RBG contains only 3 PRBs, and the bandwidth only contains 17 RBGs. The last RBG contains only 2 PRBs.

Similarly, if N clusters are allocated by a cluster, and the number of RBGs is P, then N bits of the bitmap can be used to indicate the RBGs identified by sO and si and the N PRBs of the PRBs included in one or more subsequent RBGs. In the case of allocation, "log ₂ P, bit indicates the RBG number assigned to a user terminal, ", indicating rounding up.

Therefore, it is assumed that the cluster cluster assigned to one user equipment A is S0=1 and S2=15 as an example. SO is coded as 00001 in the DCI resource allocation field, and S2 is coded as S2=01111. The first in S0 The PRB is assigned to user equipment A, and the code is 100. The first two PRBs in S2 are assigned to user equipment A, and the code is 110.

The user equipment may acquire resources according to a preset decoding rule according to field bits in the resource allocation field of the DCI.

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

With the above two embodiments, the base station can use a bitmap mode to indicate which user equipment PRB is specifically allocated in one RBG. Compared with the prior art, the minimum granularity of the resource allocation type typel can be reduced to one PRB. , not an RBG.

However, it should be noted that, in the foregoing embodiment, the value of the indication field bit may be interpreted as needed. For example, in the embodiment shown in FIG. 5, the allocation to the user equipment A may be represented by 1010. The second and fourth PRBs.

FIG. 7 is a resource allocation reference diagram of another embodiment of an uplink resource allocation method according to an embodiment of the present invention. Similarly, this embodiment is exemplified by a system bandwidth of 100 PRBs.

In the embodiment shown in Fig. 7, at least one resource block allocated to the user equipment is indicated in a manner of a specific length indication in a resource block group assigned to a user equipment.

Similar to the foregoing embodiment, it is also necessary to first distinguish the number of each RBG, for example, S0=0001 and S2=10111 indicate that the resource fast group RBG allocated to user equipment B is the first and 23rd RBGs.

Among the RBGs indicated by SI, only the first one is assigned to user equipment B, and the PRB length assigned to user equipment B is 00. In the RBG indicated by S2=10111, if consecutive 1, 2, and 3 PRBs are allocated to user equipment B, the code is 10, indicating that the PRB length allocated to user equipment B is 3. In addition, a bit indication is used. In an RBG, whether the PRB allocated to a user equipment is left-aligned or right-aligned, the embodiment shown in FIG. 7 is left-aligned, that is, several consecutive PRBs from the left are Assigned to a user device.

If a cluster is allowed to allocate N PRBs, then a "log ₂ N" bit bitmap can be used to indicate the RBG identified by s0 and si and the N of the PRBs included in one or more subsequent RBGs. The allocation of PRBs.

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

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

If a cluster is allowed to allocate N PRBs, a "log ₂ N" bit bitmap can be used to indicate the allocation of RBGs identified by sO and si and N PRBs in PRBs included in one or more subsequent RBGs.

For example, assume that the cluster cluster assigned to a user equipment C is S0=1 and S2=15 as an example. The SO is coded as 00001 in the DCI resource allocation field, and S2 is encoded as S2=01111. In the SO, only the first PRB is allocated to the user equipment A, and the code 00 indicates that only the first PRB is allocated to the user equipment C. The three PRBs in S2 are all assigned to user equipment C, and the code is 10.

In addition, a bit indication may be used. In an RBG, whether the PRB allocated to a user equipment is left-aligned or right-aligned, the embodiment shown in FIG. 8 is left-aligned, that is, several consecutive PRBs from the left are Assigned to a user device.

In the foregoing embodiment, it is of course also possible to reinterpret s2 and s3 to identify the allocation of RBs in the RBG indicated by s2 and s3.

With the foregoing two embodiments, the base station can indicate the PRB of the user equipment that is specifically allocated to the RBG in the manner of the length indication. Compared with the prior art, the minimum granularity of the resource allocation type type1 can be reduced to one. PRB, not an RBG.
