Abstract
The described technology is generally directed towards scheduling downlink transmissions using orthogonal resources (that is, resources that avoid or at least reduce interference) when a network configures a user equipment (UE) with a multiple slot configuration to repeat the HARQ-ACK information for a transmission. By using orthogonal resources, a downlink transmission can be scheduled in consecutive time slots instead of waiting for the repeated HARQ-ACKs to complete.
Claims20
A system, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising:
- establishing a connection with a user equipment, wherein the connection comprises a physical uplink control channel resource and physical downlink shared channel resources,
- transmitting data to the user equipment;
- and
- configuring the user equipment to communicate a request acknowledgement to arrange the physical uplink control channel resource to be orthogonal to the physical downlink shared channel resources with respect to overlapping transmission time slots, resulting in a channel arrangement, wherein the channel arrangement was selected to reduce an interference between the physical uplink control channel resource and physical downlink shared channel resources.
A method, comprising:
- facilitating, by a device comprising a processor, establishing a connection with network equipment, wherein the connection comprises a physical uplink control channel resource and a physical downlink shared channel;
- receiving, by the device, a transmission from the network equipment via the physical downlink shared channel;
- and
- in response to the receiving, sending, by the device, a request acknowledgement to the network equipment via a physical uplink control channel resource to arrange the physical uplink control channel resource to be orthogonal to the physical downlink shared channel resources with respect to overlapping transmission time slots, resulting in a channel arrangement, wherein the channel arrangement was selected to reduce an interference between the physical uplink control channel resource and physical downlink shared channel resources.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of an eNodeB device, facilitate performance of operations, the operations comprising:
- configuring a device to commence, in response to information transmitted by the eNodeB device to the device, communicating a hybrid automatic repeat request acknowledgement, wherein the communicating comprises communicating the hybrid automatic repeat request acknowledgement to arrange a physical uplink control channel resource to be orthogonal to physical downlink shared channel resources with respect to overlapping transmission time slots, resulting in a channel arrangement, and wherein the channel arrangement was selected to reduce an interference between the physical uplink control channel resource and physical downlink shared channel resources;
- and
- further configuring the device to repeat the communicating at an interval.
