Abstract
Apparatuses, systems, and methods for time division multiplexing of uplink communications using a first wireless link with a first radio access technology (RAT) and a second wireless link with a second RAT.
Claims20
A method, comprising:
- by a network element:
- establishing a first wireless link with a wireless device according to a first radio access technology (RAT);
- establishing a second wireless link with the wireless device according to a second RAT;
- determining a time division duplexing (TDD) schedule for uplink activity of the wireless device, wherein the schedule includes uplink activity on the first RAT at a first time and uplink activity on the second RAT at a second time different from the first time, wherein the second time includes at least a portion of one or more special subframes associated with the first RAT;
- transmitting an indication of the schedule to the wireless device;
- and
- receiving uplink activity from the wireless device on the first RAT at the first time and uplink activity from the wireless device on the second RAT according to the schedule.
4 more elements
An apparatus, comprising:
- a processor, wherein the processor is configured to cause a base station to:
- determine a time division multiplexing (TDM) schedule for a wireless device, wherein the TDM schedule for the wireless device includes uplink activity on a first radio access technology (RAT) and uplink activity on a second RAT, wherein the uplink activity on the first RAT and the uplink activity of the second RAT occur at separate times, wherein determining the TDM schedule, includes:
- allocating a first subframe to uplink activity on the first RAT;
- allocating a second subframe to downlink activity on the first RAT;
- refraining from scheduling downlink activity on the first RAT during the second subframe;
- and
- scheduling uplink activity on the second RAT during the second subframe;
- indicate the TDM schedule to the wireless device;
- and
- communicate with the wireless device according to the TDM schedule.
7 more elements
An apparatus, comprising:
- a processor, wherein the processor is configured to a cause the apparatus to:
- establish first and second wireless links with a user equipment device (UE), wherein the first wireless link uses a first radio access technology (RAT) and the second wireless link uses a second RAT;
- adjust a first schedule of the first wireless link to create a modified schedule of the first wireless link, wherein the modified schedule includes a first time for uplink transmissions on the first wireless link, wherein the modified schedule further includes a second time, wherein the second time is available for uplink transmissions on the second wireless link;
- and
- communicate with the UE according to the modified schedule.
