Abstract
Current frame structures in Long-Term Evolution (LTE) and New Radio (NR) are not designed to accommodate full duplex (FD) communication. Embodiments are disclosed in which frame structures are provided that support FD communication and frequency division duplex (FDD) communication and time division duplex (TDD) communication. In some embodiments, there is defined two separate and independent frame structures: a frame structure for reception (e.g. a downlink frame structure) and a frame structure for transmission (e.g. an uplink frame structure).
Claims18
A method performed by an apparatus, comprising:
- receiving a first indication for a first frame structure for the apparatus, wherein the first indication indicates a first frame length of a first frame in the first frame structure, a first number of time durations within the first frame for which a first respective communication direction is configured, and a second number of time durations within the first frame for which a second respective communication direction is configured, and wherein the first frame in the first frame structure includes a first time duration that is configured for the apparatus to receive a first wireless transmission on the first frame structure from a device;
- receiving a second indication for a second frame structure for the apparatus, wherein the second indication indicates a second frame length of a second frame in the second frame structure, and wherein the second frame in the second frame structure is configured for the apparatus to transmit a second wireless transmission on the second frame structure to the device, wherein the second frame includes a second time duration, and wherein the second time duration is a reserved time duration in which both transmission and reception are prohibited;
- and
- wirelessly communicating with the device according to the first frame structure and the second frame structure.

An apparatus, comprising:
- a memory to store processor-executable instructions;
- and
- at least one processor to execute the processor-executable instructions to cause the apparatus to:
- receive a first indication for a first frame structure for the apparatus, wherein the first indication indicates a first frame length of a first frame in the first frame structure, a first number of time durations within the first frame for which a first respective communication direction is configured, and a second number of time durations within the first frame for which a second respective communication direction is configured, and wherein the first frame in the first frame structure includes a first time duration that is configured for the apparatus to receive a first wireless transmission on the first frame structure from a device;
- receive a second indication for a second frame structure for the apparatus, wherein the second indication indicates a second frame length of a second frame in the second frame structure, and wherein the second frame in the second frame structure is configured for the apparatus to transmit a second wireless transmission on the second frame structure to the device, wherein the second frame includes a second time duration, and wherein the second time duration is a reserved time duration in which both transmission and reception are prohibited;
- and
- wirelessly communicate with the device according to the first frame structure and the second frame structure.
4 more elements
A method performed by a device, the method comprising:
- transmitting a first indication for a first frame structure for at least one apparatus of a plurality of apparatuses, wherein the first indication indicates a first frame length of a first frame in the first frame structure, a first number of time durations within the first frame for which a first respective communication direction is configured, and a second number of time durations within the first frame for which a second respective communication direction is configured, and wherein the first frame in the first frame structure includes a first time duration that is configured for sending a first wireless transmission on the first frame structure from the device to the at least one apparatus;
- transmitting a second indication for a second frame structure for the at least one apparatus, wherein the second indication indicates a second frame length of a second frame in the second frame structure, and wherein the second frame in the second frame structure is configured for receiving a second wireless transmission on the second frame structure from the at least one apparatus, wherein the second frame includes a second time duration, and wherein the second time duration is a reserved time duration in which both transmission and reception are prohibited;
- and
- wirelessly communicating with the at least one apparatus according to the first frame structure and the second frame structure.
