Abstract
According to some embodiments, a method in a network node comprises determining a first uplink/downlink scheduling pattern for a first plurality of consecutive subframes; transmitting the first uplink/downlink scheduling pattern to a wireless device; transmitting at least one subframe to the wireless device according to the first uplink/downlink scheduling pattern; determining a second uplink/downlink scheduling pattern for a second plurality of consecutive subframes, wherein the first plurality of consecutive subframes and the second plurality of consecutive subframes share at least one subframe; and transmitting the second uplink/downlink scheduling pattern to the wireless device.
Claims20
A method in a network node, the method comprising:
- determining a first uplink/downlink scheduling pattern for a first plurality of consecutive subframes based on a traffic pattern of data to transmit or receive;
- transmitting the first uplink/downlink scheduling pattern to a wireless device;
- transmitting or receiving at least one subframe of the first plurality of consecutive subframes to or from the wireless device according to the first uplink/downlink scheduling pattern;
- determining the traffic pattern of data to transmit or receive has changed;
- determining, based on the changed traffic pattern, a second uplink/downlink scheduling pattern for a second plurality of consecutive subframes, wherein the first plurality of consecutive subframes and the second plurality of consecutive subframes overlap in time by at least one shared subframe;
- transmitting the second uplink/downlink scheduling pattern to the wireless device;
- and
- transmitting or receiving the at least one shared subframe;
- wherein the first uplink/downlink scheduling pattern comprises at least one of:
- a set of subframes in the first plurality of subframes that the wireless device does not monitor for downlink;
- and
- a set of subframes in the first plurality of subframes that the wireless device does monitor for downlink.
A method in a wireless device, the method comprising:
- receiving, from a network node, a first uplink/downlink scheduling pattern for a first plurality of consecutive subframes;
- receiving or transmitting at least one subframe according to the first uplink/downlink scheduling pattern;
- receiving, from the network node, a second uplink/downlink scheduling pattern for a second plurality of consecutive subframes, wherein the first plurality of consecutive subframes and the second plurality of consecutive subframes overlap in time by at least one shared subframe;
- and
- transmitting or receiving the at least one shared subframe;
- wherein the first uplink/downlink scheduling pattern comprises at least one of:
- a set of subframes in the first plurality of subframes that the wireless device does not monitor for downlink;
- and
- a set of subframes in the first plurality of subframes that the wireless device does monitor for downlink.
A network node comprising a processor and a memory, the processor operable to:
- determine a first uplink/downlink scheduling pattern for a first plurality of consecutive subframes based on a traffic pattern of data to transmit or receive;
- transmit the first uplink/downlink scheduling pattern to a wireless device;
- transmit or receive at least one subframe of the first plurality of consecutive subframes to or from the wireless device according to the first uplink/downlink scheduling pattern;
- determine the traffic pattern of data to transmit or receive has changed;
- determine, based on the changed traffic pattern, a second uplink/downlink scheduling pattern for a second plurality of consecutive subframes, wherein the first plurality of consecutive subframes and the second plurality of consecutive subframes overlap in time by at least one shared subframe;
- transmit the second uplink/downlink scheduling pattern to the wireless device;
- and
- transmit or receive the at least one shared subframe;
- wherein the first uplink/downlink scheduling pattern comprises at least one of:
- a set of subframes in the first plurality of subframes that the wireless device does not monitor for downlink;
- and
- a set of subframes in the first plurality of subframes that the wireless device does monitor for downlink.
A wireless device comprising a processor and a memory, the processor operable to:
- receive, from a network node, a first uplink/downlink scheduling pattern for a first plurality of consecutive subframes;
- receive or transmit at least one subframe according to the first uplink/downlink scheduling pattern;
- receive, from the network node, a second uplink/downlink scheduling pattern for a second plurality of consecutive subframes, wherein the first plurality of consecutive subframes and the second plurality of consecutive subframes overlap in time by at least one shared subframe;
- and
- transmit or receive the at least one shared subframe;
- wherein the first uplink/downlink scheduling pattern comprises at least one of:
- a set of subframes in the first plurality of subframes that the wireless device does not monitor for downlink;
- and
- a set of subframes in the first plurality of subframes that the wireless device does monitor for downlink.
