Abstract
A network node configures a frame structure for a new radio access technology (RAT). The network nodes configures a frame including a fixed number of subframes, each of subframe including at least one resource unit (RU) based on a numerology, and schedules a channel in the frame by using a reference timing corresponding to a subframe.
Claims22
A method performed by a network node in a wireless communication system, the method comprising:
- configuring a frame including subframes, wherein each of the subframes includes at least one resource unit (RU);
- and
- scheduling a channel in the frame based on the at least one RU,
- wherein the at least one RU is a time granularity to schedule the channel,
- wherein the at least one RU comprises a first RU for scheduling a control channel and a second RU for scheduling a data channel,
- wherein a time duration of the first RU is smaller than a time duration of the second RU,
- wherein the time duration of the first RU and the time duration of the second RU are different per each of the subframes in the frame,
- wherein, based on (i) a subframe index of end of data transmission being n and (ii) a data rate being greater than a first predefined rate:
- a minimum timing for acknowledgement/negative-acknowledgement (A/N) transmission is configured as n+k, where k is 2 or 3,
- wherein, based on (i) the subframe index of end of data transmission being n and (ii) the data rate being lower than the first predefined rate and greater than a second predefined rate:
- the minimum timing for A/N transmission is configured as n+k1 , where k1 is 1, and
- wherein, based on (i) the subframe index of end of data transmission being n and (ii) the data rate being lower than the second predefined rate:
- the minimum timing for A/N transmission is configured as n+k2, where k2 is 12.

- wherein the at least one RU comprises a first RU for scheduling a control channel and a second RU for scheduling a data channel,
- wherein a time duration of the first RU is smaller than a time duration of the second RU,
- wherein the time duration of the first RU and the time duration of the second RU are different per each of the subframes in the frame,
- wherein, based on (i) a subframe index of end of data transmission being n and (ii) a data rate being greater than a first predefined rate:
- a minimum timing for acknowledgement/negative-acknowledgement (A/N) transmission is configured as n+k, where k is 2 or 3,
- wherein, based on (i) the subframe index of end of data transmission being n and (ii) the data rate being lower than the first predefined rate and greater than a second predefined rate:
- the minimum timing for A/N transmission is configured as n+k1, where k1 is 1, and
- wherein, based on (i) the subframe index of end of data transmission being n and (ii) the data rate being lower than the second predefined rate, the minimum timing for A/N transmission is configured as n+k2, where k2 is 12.
