Abstract

Aspects of the present disclosure provide a scheduling entity and methods of operating the scheduling entity such that the scheduling entity reconfigures/allocates its resources based on device capabilities of the wireless devices. The scheduling entity utilizes a first resource configuration to provide communications service to one or more wireless devices associated with the scheduling entity. The scheduling entity determines a change of the one or more wireless devices, wherein the change include at least one of a capability change of a wireless device, a quality of service (QoS) requirement change of a wireless device, an addition of a wireless device, or a removal of a wireless device. Based on at least one of a predetermined time of a day or the determined change, the scheduling entity reconfigures to a second resource configuration to facilitate resource utilization of the first wireless cell.

Claims34

Dependent claims

A method of operating a scheduling entity to facilitate resource utilization of the scheduling entity, comprising:

utilizing, at the scheduling entity, a first resource configuration of radio access technologies (RATs) and features associated with the RATs, to provide communications service to a plurality of wireless devices;
receiving a capability report from each of the plurality of wireless devices, the capability report indicating one or more supported RATs, frequency bands, and support of carrier aggregation (CA) for each RAT;
determining, based on the capability report, a capability change of the plurality of wireless devices indicating at least one of a change of the supported RATs, a change of the frequency bands, or a change of the support of CA for each RAT;
and
reconfiguring the scheduling entity to a second resource configuration of the RATs and features associated with the RATs, based on at least one of a predetermined time of a day or the determined capability change to meet capabilities and quality of service (QoS) requirements of the plurality of wireless devices, the reconfiguring comprising:
determining a cost associated with the second resource configuration, wherein the cost corresponds to a QoS requirement change of one or more of the wireless devices;
and
allocating resources of the scheduling entity such that the cost is equal to or lower than a threshold value.

5 more elements

A scheduling entity, comprising:

a communication interface configured to communicate with a plurality of wireless devices;
a memory comprising executable code;
and
a processor operatively coupled to the communication interface and the memory,
wherein the processor is configured when executing the code, to:
utilize a first resource configuration of radio access technologies (RATs) and features associated with the RATs, to provide communications service to a plurality of wireless devices;
receiving a capability report from each of the plurality of wireless devices, the capability report indicating one or more supported RATs, frequency bands, and support of carrier aggregation (CA) for each RAT;
determine, based on the capability report, a capability change of the plurality of wireless devices indicating at least one of a change of the supported RATs, a change of the frequency bands, or a change of the support of CA for each RAT;
and
reconfigure to a second resource configuration of the RATs and features associated with the RATs based on at least one of a predetermined time of a day or the determined capability change to match capabilities and quality of service (QoS) requirements of the plurality of wireless devices, the reconfiguring comprising:
determining a cost associated with the second resource configuration, wherein the cost corresponds to a QoS requirement change of one or more of the wireless devices;
and
allocating resources of the scheduling entity such that the cost is equal to or lower than a threshold value.

10 more elements

A scheduling entity, comprising:

means for utilizing a first resource configuration of radio access technologies (RATs) and features associated with the RATs, to provide communications service to a plurality of wireless devices;
means for receiving a capability report from each of the plurality of wireless devices, the capability report indicating one or more supported RATs, frequency bands, and support of carrier aggregation (CA) for each RAT;
means for determining, based on the capability report, a capability change of the plurality of wireless devices indicating at least one of a change of the supported RATs, a change of the frequency bands, or a change of the support of CA for each RAT;
and
means for reconfiguring to a second resource configuration of the RATs and features associated with the RATs, based on at least one of a predetermined time of a day or the determined capability change to meet capabilities and quality of service (QoS) requirements of the plurality of wireless devices, the reconfiguring comprising:
determining a cost associated with the second resource configuration, wherein the cost corresponds to a QoS requirement change of one or more of the wireless devices;
and
allocating resources of the scheduling entity such that the cost is equal to or lower than a threshold value.

5 more elements

A non-transitory computer-readable medium comprising executable code for causing a scheduling entity to:

utilize a first resource configuration of radio access technologies (RATs) and features associated with the RATs, to provide communications service to a plurality of wireless devices;
receiving a capability report from each of the plurality of wireless devices, the capability report indicating one or more supported RATs, frequency bands, and support of carrier aggregation (CA) for each RAT;
determine, based on the capability report, a capability change of the plurality of wireless devices indicating at least one of a change of the supported RATs, a change of the frequency bands, or a change of the support of CA for each RAT;
and
reconfigure the scheduling entity to a second resource configuration of the RATs and features associated with the RATs, based on at least one of a predetermined time of a day or the determined capability change to meet capabilities and quality of service (QoS) requirements of the plurality of wireless devices, the reconfiguring comprising:
determining a cost associated with the second resource configuration, wherein the cost corresponds to a QoS requirement change of one or more of the wireless devices;
and
allocating resources of the scheduling entity to minimize the cost.
