Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The third Generation Partnership Project (3rd Generation Partnership Project, 3GPP) defines three major directions for the application scenario of the fifth Generation mobile communication technology (5th-Generation, 5G): enhanced Mobile Broadband (eMBB); mass Machine type communication (Mass Machine type communication, abbreviated as mMTC); high reliability Communication (Ultra Reliable & Low Latency Communication, abbreviated as: uRLLC). The application scene of the eMBB mainly aims at the large-flow mobile broadband services such as three-dimensional (3D) video or ultra-high-definition video and the like; the mMTC is an application scene of the Internet of things, and mainly relates to information interaction between people and objects; the application scenario of URLLC is mainly for services requiring low-delay and high-reliability connection, such as unmanned driving, industrial automation, and the like.

Since the fourth Generation Mobile communication technology (4th-Generation, abbreviated as: 4G) is designed to serve only one service, namely, Mobile Broadband (MBB), the 5G is designed to serve the three services, for example: the 5G needs to serve the eMBB service and the URLLC service simultaneously, so the 5G needs to multiplex the service resources of the eMBB and the URLLC service, and therefore, a new method needs to be introduced into the design of the control channel in the 5G, so that the URLLC service can preempt the resources already allocated by the base station for the eMBB service, and the eMBB service is not affected basically.

According to the method and the device, the resource distributed to the terminal equipment by the base station is carried in the resource distribution message determined by the base station for the service of the terminal equipment, and the resource occupied by other terminal equipment in the resource distributed to the service of the terminal equipment by the base station is also carried, so that the terminal equipment can know the resource occupied by other terminal equipment when analyzing the resource distribution message sent by the base station, the problem that the terminal equipment generates error codes during decoding is avoided, the decoding efficiency is improved, and the multiplexing of the resource of the same terminal equipment is realized.

Taking the resource allocated by the URLLC service preemption base station for the eMBB service as an example, the resource allocation message determined by the base station for the eMBB service of the eMBB terminal device not only carries the resource allocated by the base station for the eMBB terminal device, but also carries the resource preempted by the URLLC terminal device in the resource allocated by the base station for the eMBB service of the eMBB terminal device, so that the eMBB terminal device can know the resource preempted by the URLLC terminal device when resolving the resource allocation message sent by the base station, thereby avoiding the problem of error code generated by the eMBB terminal device during decoding.

Fig. 1 is a flowchart illustrating a resource allocation method according to an exemplary embodiment, where the resource allocation method is applied to a terminal device, as shown in fig. 1, and the resource allocation method includes the following steps S101 to S103:

in step S101, a resource allocation message sent by a base station is received, where the resource allocation message includes: the base station allocates resources and resource preemption information for the terminal equipment, and the resource preemption information represents resources preempted by other terminal equipment in the resources.

When the base station allocates resources for the terminal equipment, reserving a part of resources in a resource allocation message sent by the base station for the terminal equipment, wherein the reserved resources are used for transmitting resource preemption information, and the resource preemption information is used for explaining the resources which are preempted by other terminal equipment in the resources allocated by the base station for the terminal equipment; the resource preemption information may or may not be null.

When the resource preemption information in the resource allocation message sent by the base station to the terminal equipment is empty, the resource preemption information indicates that the resource allocated by the base station to the terminal equipment is not preempted by other terminal equipment, and the terminal equipment can transmit service data by using all resources allocated by the base station to the terminal equipment; when the resource preemption information in the resource allocation message sent by the base station to the terminal equipment is not empty, it indicates that the resource allocated by the base station to the terminal equipment is preempted by other terminal equipment, and the terminal equipment cannot use all the resources allocated by the base station to the terminal equipment to transmit service data, but only can use the resources allocated by the base station to the terminal equipment and not preempted by other terminal equipment to transmit service data.

In step S102, the resource allocation message is parsed to obtain the non-preempted resources in the resources.

When the terminal equipment receives the resource allocation message sent by the base station, decoding the resource allocation message, and determining the resource occupied by other terminal equipment in the resources allocated by the base station for the terminal equipment and the resource allocated by the base station for the terminal equipment from the resource allocation message; and then determining the resources which are not preempted in the resources according to the resources distributed by the base station for the terminal equipment and the resources preempted by other terminal equipment in the resources.

In step S103, the service data is transmitted through the resource that is not preempted.

When the terminal equipment analyzes the resources which are not preempted in the resources allocated by the base station for the terminal equipment, the terminal equipment also analyzes the available resources of the resources allocated by the base station for the terminal equipment to transmit the service data, so that when the transmitted service data is decoded, the decoding can be correctly performed from the resources which are not preempted, the error code problem caused when the preempted resources are decoded simultaneously in the decoding process is avoided, and the decoding failure is avoided.

The step of transmitting the service data through the non-preempted resources comprises the following steps: and transmitting the service data through the non-preempted resources, or transmitting the service data through the non-preempted resources, so as to receive the service data.

When the terminal device decodes the service data, the preempted resources need to be considered, and the preempted resources are combined with the non-preempted resources to decode the service data corresponding to the terminal device, so that the terminal device must know which resources are preempted and which resources are not preempted in the decoding process to correctly decode. In the present disclosure, the resource allocation message sent by the base station to the terminal device not only carries the resource allocated by the base station to the terminal device, but also carries the resource preempted by other terminal devices in the resource allocated by the base station to the terminal device, so that the terminal device can correctly decode the service data corresponding to itself.

The embodiment of the disclosure provides a resource allocation method, which includes: receiving a resource allocation message sent by a base station, wherein the resource allocation message comprises: the base station allocates resources for the terminal equipment and resource preemption information used for indicating resources preempted by other terminal equipment in the resources, further analyzes the resource allocation message, acquires resources which are not preempted in the resources, and transmits service data through the resources which are not preempted. The resource allocation message sent by the base station for the terminal device not only carries the resource allocated by the base station for the terminal device, but also carries the resource preempted by other terminal devices in the resource allocated by the base station for the terminal device, so that the terminal device can know the resource preempted by other terminal devices when analyzing the resource allocation message sent by the base station, thereby avoiding the problem of error code generated by the terminal device during decoding, and improving decoding efficiency.

The base station allocates resources for the terminal equipment as follows: a base station distributes a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols for terminal equipment; the resource preemption information is as follows: the OFDM symbols which are preempted by other terminal equipment in the plurality of OFDM symbols; in one embodiment, as shown in fig. 2, the above step S102 may be implemented as steps S1021 to S1022, the above step S103 may be implemented as step S1031,

in step S1021, the resource allocation message is parsed to determine OFDM symbols that are preempted by other terminal devices in the plurality of OFDM symbols.

In step S1022, according to the plurality of OFDM symbols and the OFDM symbol which is preempted by other terminal devices in the plurality of OFDM symbols, the OFDM symbol which is not preempted in the plurality of OFDM symbol resources is determined.

In step S1031, the traffic data is transmitted via the non-preempted OFDM symbols.

As shown in fig. 3, it is assumed that a User Equipment (User Equipment, hereinafter, referred to as UE)1 of a base station allocates 14 OFDM symbols, and a resource allocation message sent by the base station to the UE1 includes: the base station allocates resources of 14 OFDM symbols (OFDM 1-OFDM14 respectively) to the UE1 for transmitting service data, and the OFDM symbols preempted by the UE2 in the 14 OFDM symbols are OFDM10-OFDM 14; after the UE1 analyzes the resource allocation message, it is known that the OFDM symbol preempted by the UE2 in the 14 OFDM symbols allocated by the base station is OFDM10-OFDM14, the UE1 combines the OFDM1-OFDM14 allocated by the base station for the UE and the OFDM10-OFDM14 preempted by the UE2, and it is known that the OFDM symbol which is not preempted is OFDM1-OFDM9, so that the UE1 transmits its own service data by using OFDM1-OFDM9, and when decoding the service data, only the service data transmitted by OFDM1-OFDM9 is considered, and the service data transmitted by OFDM10-OFDM14 is not considered.

In one embodiment, the resource preemption information described above is carried within any one of a plurality of OFDM symbols.

In an implementation manner, the resource preemption information carried in the resource allocation message sent by the base station to the terminal device may be carried in an OFDM symbol allocated by any one base station to the terminal device.

Since the first OFDM symbols of the plurality of OFDM symbols allocated to the terminal device by the base station are used to carry the control information related to the decoding of the terminal device in the existing standard, in order to change the existing standard as little as possible, the resource preemption information may be carried in OFDM symbols that are not used to carry the control information related to the decoding of the terminal device.

In yet another implementation, as shown in fig. 4, the resource preemption information may be carried in the last OFDM symbol of a plurality of OFDM symbols allocated by the base station to the terminal device.

The base station allocates resources for the terminal equipment as follows: a base station distributes a plurality of resource blocks for terminal equipment; the resource preemption information is as follows: resource blocks which are occupied by other terminal equipment in the plurality of resource blocks; in one embodiment, as shown in fig. 5, the step S102 can be implemented as steps S1023 to S1024, the step S103 can be implemented as step S1032,

in step S1023, the resource allocation message is parsed, and resource blocks in the plurality of resource blocks that are preempted by other terminal devices are determined;

in step S1024, according to the plurality of resource blocks and resource blocks occupied by other terminal devices in the plurality of resource blocks, determining resource blocks not occupied in the plurality of resource blocks;

in step S1032, the traffic data is transmitted through the resource blocks that are not preempted.

Suppose that a User Equipment (UE) 1 of a base station allocates 10 resource blocks, and a resource allocation message sent by the base station to the UE1 includes: the base station allocates resource transmission service data of 10 resource blocks (respectively, resource block 1-resource block 10) to the UE1, and the resource block preempted by the UE2 in the 10 resource blocks is resource block 8-resource block 10; after the UE1 parses the resource allocation message, it knows that the resource block preempted by the UE2 is the resource block 8-resource block 10 among the 10 resource blocks allocated by the base station, and the UE1 combines the resource block 1-resource block 10 allocated by the base station and the resource block 8-resource block 10 preempted by the UE2, and knows that the resource block not preempted is the resource block 1-resource block 7, then the UE1 transmits its own service data using the resource block 1-resource block 7, and when decoding the service data, only the service data transmitted by the resource block 1-resource block 7 is considered, and the service data transmitted by the resource block 8-resource block 10 does not need to be considered.

In one embodiment, the resource preemption information is carried within any one of a plurality of resource blocks.

In an implementation manner, when the resource allocated by the base station to the terminal device is a resource block, at this time, the resource preemption information may be carried in any resource block of the plurality of resource blocks;

due to the corresponding relationship between the RB and the bandwidth, the resource preemption information can be carried in n bits downward from the start position of the bandwidth allocated by the base station to the terminal device, or the resource preemption information can be carried in n bits in the middle position of the bandwidth allocated by the base station to the terminal device, or the resource preemption information can be carried in n bits upward from the end position of the bandwidth allocated by the base station to the terminal device.

Assuming that the bandwidth allocated to the terminal device by the base station is 1Mhz-5Mhz, as shown in fig. 6, the resource preemption information can be carried in n bits downward from the starting position of 1 Mhz; as shown in fig. 7, the resource preemption information can be carried in n bits downward from the start position of 3 Mhz; as shown in fig. 8, the resource preemption information can be carried in n bits up to the end position of 5 Mhz.

If the resource preempted by other terminal devices in the resources allocated by the base station for the terminal device is directly carried in the resource allocation information, more resources may be wasted, and therefore, in order to save resources, in an implementable manner, the resource preemption code and the resource preemption information table may be used to determine the resource preemption information.

In one embodiment, as shown in fig. 9, the step S102 may be implemented as: step 1025-step S1027;

in step S1025, the resource allocation message is decoded to obtain the resource preemption code.

In step S1026, a resource to be preempted by other terminal devices in the resource is determined according to the resource preemption code and a pre-stored resource preemption information table, where the resource preemption information table includes: and the corresponding relation between the resources preempted by other terminal equipment in the resources and the resource preemption codes.

In one implementation, the resource preemption code may be represented by an N-bit binary number, such as: may be represented by a 2-bit binary number, or may be represented by a 5-bit binary number, etc. Since the binary number of N bits can identify 2XN numbers, if each number represents a resource that is preempted by other terminal devices in a resource, there can be 2XN representations.

In step S1027, a resource that is not preempted in the resource is determined according to the resource and a resource that is preempted by another terminal device in the resource.

For example: the resource preemption code is marked by a 2-bit 2-ary number, so that 2 bits are needed to carry the resource preemption code in fig. 6, and at this time, the resource preemption code can be expressed as: 00. 01, 10 and 11, each resource preemption code corresponding to a resource that is preempted by other terminal devices in the resources allocated to the terminal device by the base station, as shown in table 1, the relationship between the resource preemption code and the preempted resource is shown in table 1,

TABLE 1

Resource preemption code	Preemptive resource location
		00	Fourth and fifth resource blocks
01	Third and sixth resource blocks
		10	Second and fourth resource blocks
11	Second and third resource blocks

When the resource preemption code carried in fig. 6 is 10, it can be determined from table 1 that the resources preempted by other terminal devices in the resources allocated by the base station for the terminal device are the second and fourth resource blocks.

The resource allocation message further comprises: modulation and Coding Scheme (MCS) information;

in one embodiment, as shown in fig. 10, the step S102 may be further implemented as: step S1028.

In step S1028, the resource allocation message is decoded according to the MCS information, and a resource that is not preempted in the resource is obtained.

In an implementation manner, the resource allocation message may also carry MCS information, and after the terminal device obtains the MCS parameter resource allocation message, the resource preemption information is decoded according to the MCS information to obtain resources preempted by other terminal devices in the resources allocated by the base station for the terminal device; and then acquiring the resources which are not preempted in the resources allocated to the terminal equipment by the base station according to the resources allocated to the terminal equipment by the base station and the resources preempted by other terminal equipment in the resources allocated to the terminal equipment by the base station.
