Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for scheduling uplink primary and secondary carrier users.
Background
In the current LTE system, a single carrier supports a maximum system bandwidth of 20M, and if a larger bandwidth is to be supported, a carrier aggregation technique needs to be adopted.
In the 3GPP protocol, aggregation of a maximum of 5 carriers is supported, but the number of downlink carriers is required to be equal to or greater than the number of uplink carriers. In a public network operator network, the general downlink service requirement is greater than the uplink service requirement, and the carrier aggregation defined by 3GPP can better satisfy the operator network.
However, in some industry network applications, there are a large number of video monitoring services, and at this time, the uplink service requirement is greater than the downlink service requirement, and in this case, the carrier aggregation scheme defined by 3GPP cannot well meet the requirements of the industry network.
In order to better satisfy a large number of uplink service demand scenarios, an asymmetric carrier aggregation technology in which the number of uplink carriers is greater than the number of downlink carriers needs to be introduced.
Referring to fig. 1, fig. 1 is a schematic diagram of asymmetric uplink carrier aggregation. Fig. 1 includes N downlink carriers and M uplink carriers, where M is greater than N.
For asymmetric carrier aggregation, it can be decomposed into the form as in fig. 2. Referring to fig. 2, fig. 2 is an exploded view of asymmetric uplink carrier aggregation. Each carrier aggregation cluster comprises one downlink carrier and one or more uplink carriers. The downlink carrier and the corresponding uplink carrier are defined as a primary carrier, and the other uplink carriers are defined as secondary carriers.
Aggregation between multiple carrier aggregation clusters is actually aggregation between primary carriers, which is equivalent to carrier aggregation defined in 3 GPP.
One downlink carrier corresponds to a plurality of uplink carriers, the plurality of uplink carriers need to share the PDCCH resources of the downlink carrier, the bandwidths of the plurality of uplink carriers are possibly different, and when each uplink carrier is allocated with the corresponding PUSCH resource, the PDCCH resources of the downlink carrier need to be simultaneously and independently allocated, and the uplink main carrier and the uplink auxiliary carrier are respectively scheduled, so that the fairness of users cannot be ensured, and the throughput is maximized.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings and examples.
The embodiment of the application provides a method for scheduling uplink main and auxiliary carriers, which introduces the user priority of the carriers to perform joint scheduling on a plurality of uplink carriers (main carriers and auxiliary carriers), reasonably allocates Physical Downlink Control Channel (PDCCH) resources and Physical Uplink Shared Channel (PUSCH) resources, and can ensure user fairness and throughput maximization.
The following describes in detail a process of implementing uplink primary and secondary carrier user scheduling in an embodiment of the present application with reference to the accompanying drawings.
Referring to fig. 3, fig. 3 is a schematic diagram of a scheduling process of an uplink primary and secondary carrier user in the embodiment of the present application. The method comprises the following specific steps:
The user priority is calculated according to the information such as channel quality, user rate and the like, the calculation process can be realized according to the existing implementation, and the mode of acquiring the user priority is not limited here.
And step 302, the base station allocates PDCCH resources and PUSCH resources to users under each carrier according to the user priority of the primary and secondary carriers.
When the PDCCH resource and PUSCH resource allocation is specifically realized, the method can be realized in the following two ways:
first, all carriers (uplink primary carrier and secondary carrier) are processed in a uniform order from large to small according to the user priority of each carrier, that is, PDCCH resources and PUSCH resources are preferentially allocated to carriers with relatively high priority among the carriers.
In this way, the PDCCH resource is that of the primary carrier, and the primary and secondary carriers are not distinguished;
for the distribution of PUSCH resources, if the user is a main carrier user, the PUSCH resources are distributed in the PUSCH resource range of the main carrier;
and if the user is an auxiliary carrier user, performing PUSCH resource allocation in the PUSCH resource range of the auxiliary carrier.
The PUSCH resources are divided into PUSCH resources of a primary carrier and PUSCH resources of a secondary carrier in advance in protocol specification.
And the second method comprises the following steps:
the main and auxiliary carriers are divided into high priority carriers and low priority carriers, that is, the main and auxiliary carriers are divided into two types of carriers, and the specific division mode can be as follows:
in the first mode, a main carrier is used as a high-priority carrier, and an auxiliary carrier is used as a low-priority carrier;
in the second method, the secondary carrier is used as a high priority carrier, and the primary carrier is used as a low priority carrier.
In specific implementation, which way to divide the carrier is used may be determined according to an actual application environment, and is not limited here.
The following describes in detail a process for implementing PDCCH resource and PUSCH resource allocation on the premise of dividing high and low priority carriers with reference to the accompanying drawings.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a process of implementing PDCCH resource and PUSCH resource allocation on the premise of dividing carriers with high and low priorities in the embodiment of the present application. The method comprises the following specific steps:
When PDCCH resource pre-allocation is carried out, PDCCH resources are pre-allocated to carriers with high user priority preferentially, and the carriers with low user priority are ensured not to search the pre-allocated PDCCH resource positions; the pre-allocated PDCCH resources comprise PDCCH resource positions and resource numbers.
In the embodiment of the application, when the PDCCH resources are pre-allocated, only the user priority is introduced, PDCCH resource pre-allocation is performed on the high-priority carrier with the high priority for the user priority, and PDCCH resource pre-allocation is performed on the low-priority carrier with the low priority for the user priority. The process of pre-allocating PDCCH resources for each carrier is the same as in the prior art.
And step 402, aiming at the high-priority carrier, the base station allocates PDCCH resources and PUSCH resources for the user under the high-priority carrier according to the PDCCH resources pre-allocated to the high-priority carrier and the user priority of the high-priority carrier.
In this step, when allocating PDCCH resources and PUSCH resources to users in a high priority carrier, the priority allocates PDCCH resources and PUSCH resources to users in a high priority carrier with a high user priority, where PDCCH resources are allocated to PDCCH resources pre-allocated to the high priority carrier, and PUSCH resources are allocated within a PUSCH resource range of the high priority carrier.
And 403, aiming at the low-priority carrier, when the allocation of the PDCCH resource and the PUSCH resource for the user under the high-priority carrier is finished, the base station allocates the PDCCH resource and the PUSCH resource for the user under the low-priority carrier according to the user priority of the low-priority carrier and the PDCCH resource pre-allocated for the low-priority carrier.
In the step, when allocating PDCCH resources and PUSCH resources to users under low-priority carriers, the PDCCH resources and PUSCH resources are preferentially allocated to the users under the low-priority carriers with high user priority, wherein the PDCCH resources are allocated to the PDCCH resources pre-allocated to the low-priority carriers; and allocating PUSCH resources within the PUSCH resource range of the carrier with low priority.
In the embodiment of the present application, a PDCCH resource and a PUSCH resource are determined for a user in which carrier is allocated according to a user priority for a carrier with a low priority and a carrier with a high priority, and as for the process of specifically allocating the PDCCH resource and the PUSCH resource for the user in which carrier, the process is implemented in the prior art, which is not limited here.
And aiming at the PDCCH resources pre-allocated to the high-priority carrier, if the PDCCH resources are left after the PDCCH resources are allocated to the user under the high-priority carrier, the PDCCH resources are pre-allocated to the low-priority carrier. That is, if the PDCCH resource pre-allocated to the high priority carrier is not used up when being allocated to the user of the high priority carrier, there is a surplus, and the PDCCH resource can be allocated to the user of the low priority carrier.
