Abstract

Embodiments of the present invention provide a data sending method, a data receiving method, user equipment, and a base station. The method includes: receiving, by UE, an uplink scheduling grant, where the uplink scheduling grant includes first resource indication information; determining, by the UE, a target resource based on the first resource indication information, where the target resource is allocated resource blocks in M basic resource elements; and sending, by the UE, uplink data on the target resource. In the embodiments of the present invention, service coverage of a base station can be significantly improved.

First claim

What is claimed is:

1. A data sending method comprising:
receiving, by user equipment (UE), an uplink scheduling grant indicating a carrier for the UE to send uplink data, the carrier being evenly divided into N basic resource units, wherein N is a natural number and N>1, wherein each of the N basic resource units comprises multiple continuous resource blocks, wherein a target resource that is to be allocated to the UE is evenly distributed in the N basic resource units, wherein the uplink scheduling grant comprises first resource indication information indicating location information of allocated resource blocks in only one of the N basic resource units, and wherein the allocated resource blocks in one of the N basic resource units are part of all the resource blocks in one of the N basic resource units;
determining, by the UE, the target resource distributed in all the N basic resource units based on the first resource indication information indicating location information of allocated resource blocks in only one of the N basic resource units, wherein the target resource is a combination of the allocated resource blocks in each of the N basic resource units, and a location of the allocated resource blocks in each of the N basic resource units has the same relative location as a location indicated by the location information in the first resource indication information; and
sending, by the UE, the uplink data on the target resource.

2. The method according to claim 1 , further comprising:
determining, by the UE, a resource allocation type on the carrier for the UE to send the uplink data; and
in response to determining that the determined resource allocation type is a basic-resource-element-based resource allocation type, determining, by the UE, the target resource based on the first resource indication information, and sending the uplink data on the target resource;
in response to determining that the determined resource allocation type is a first resource-block-based resource allocation type, determining, by the UE, a location of a start resource block and a location of an end resource block in the allocated resource blocks on the carrier based on resource allocation indication information in the uplink scheduling grant, and sending the uplink data on the start resource block, the end resource block, and all resource blocks between the start resource block and the end resource block; and/or
in response to determining that the determined resource allocation type is a second resource-block-based resource allocation type, determining, by the UE, a location of a first start resource block of a start resource block, a location of a first end resource block, a location of a second start resource block, and a location of a second end resource block in the allocated resource blocks on the carrier based on resource allocation indication information in the uplink scheduling grant, and sending the uplink data on the target resource consisting of the first start resource block, the first end resource block, all resource blocks between the first start resource block and the first end resource block, the second start resource block, the second end resource block, and all resource blocks between the second start resource block and the second end resource block.

3. The method according to claim 2 , wherein the determining a resource allocation type comprises:
determining, by the UE, the resource allocation type on the carrier depending on whether the carrier is on an unlicensed spectrum; or
receiving, by the UE, third resource indication information, and determining the resource allocation type on the carrier based on the third resource indication information, wherein the third resource indication information is received by the UE by using higher layer signaling or is carried in the uplink scheduling grant.

4. A data receiving method comprising:
sending, by a base station, an uplink scheduling grant to user equipment (UE), wherein the uplink scheduling grant indicates a carrier for the UE to send uplink data, the carrier being evenly divided into N basic resource units, wherein N is a natural number and N>1, wherein each of the N basic resource units comprises multiple continuous resource blocks, wherein a target resource that is to be allocated to the UE is evenly distributed in the N basis resource units, wherein the uplink scheduling grant comprises first resource indication information indicating location information of allocated resource blocks in only one of the N basic resource units, and wherein the allocated resource blocks in one of the N basic resource units are part of all the resource blocks in one of the N basic resource units; and
receiving, by the base station, the uplink data on the target resource distributed in all the N basic resource units that is a combination of the allocated resource blocks in each of the N basic resource units, wherein the target resource has been determined based on the first resource indication information indicating location information of allocated resource blocks in only one of the N basic resource units, wherein a location of the allocated resource blocks in each of the N basic resource units has the same relative location as a location indicated by the location information in the first resource indication information.

5. The method according to claim 4 , further comprising:
sending, by the base station, third resource indication information to the UE, wherein the third resource indication information indicates that a resource allocation type on the carrier is a basic-resource-element-based resource allocation type or a resource-block-based resource allocation type, the resource-block-based resource allocation type comprises a first resource-block-based resource allocation type and/or a second resource-block-based resource allocation type, and the third resource indication information is sent by the base station to the UE by using higher layer signaling or is carried in the uplink scheduling grant.

6. User equipment (UE) comprising:
a transceiver;
a non-transitory memory storage comprising instructions; and
one or more hardware processors in communication with the non-transitory memory storage, wherein the one or more hardware processors execute the instructions to:
receive an uplink scheduling grant indicating a carrier for the UE to send uplink data, the carrier being evenly divided into N basic resource units, wherein N is a natural number and N>1, wherein each of the N basic resource units comprises multiple continuous resource blocks, wherein a target resource that is to be allocated to the UE is evenly distributed in the N basis resource units, wherein the uplink scheduling grant comprises first resource indication information indicating location information of allocated resource blocks in only one of the N basic resource units, and wherein the allocated resource blocks in one of the N basic resource units are part of all the resource blocks in one of the N basic resource units;

determine the target resource distributed in all the N basic resource units based on the first resource indication information indicating location information of allocated resource blocks in only one of the N basic resource units, wherein the target resource is a combination of the allocated resource blocks in each of the N basic resource units, and a location of the allocated resource blocks in each of the N basic resource units has the same relative location as a location indicated by the location information in the first resource indication information; and
send, using the transceiver, the uplink data on the target resource.

7. The user equipment according to claim 6 , the one or more hardware processors further execute the instructions to:
determine a
