Abstract
A method for data receiving at a base station is provided. The base station receives data using a first transmission resource in a first symbol of an uplink control channel from a first UE. The base station receives UL data or control information using a second transmission resource in a second symbol of the uplink control channel from a second UE as well. The first symbol and the second symbol have different numerologies at a same sub band.
Claims25
A method, performed by a base station in a communication network, the method comprising:
- receiving an uplink data transmission using a first transmission resource in a first symbol of an uplink control channel;
- receiving uplink data or control information using a second transmission resource in a second symbol of the uplink control channel;
- wherein the uplink control channel is within a frequency sub-band that comprises a first partial sub-band with a sub-carrier spacing of 30 kHz and a second partial sub-band with a sub-carrier spacing of 60 kHz;
- wherein the first symbol is within the first partial sub-band with the sub-carrier spacing of 30 kHz;
- wherein the second symbol is within the second partial sub-band with the sub-carrier spacing of 60 kHz;
- the method further comprising:
- receiving further uplink data or control information using a third transmission resource in a third symbol of the uplink control channel, the third symbol within the second partial sub-band with the sub-carrier spacing of 60 kHz;
- wherein a time duration of the first symbol is twice a time duration of the second symbol and is twice a time duration of the third symbol;
- and
- wherein a start of the first symbol within the first partial sub-band is time aligned with a start of the second symbol within the second partial sub-band, and an end of the first symbol within the first partial sub-band is time aligned with an end of the third symbol within the second partial sub-band.

- receiving at a base station in a communication network, an uplink data transmission using a first transmission resource in a first symbol of an uplink control channel;
- receiving at the base station, uplink control information using a second transmission resource in a second symbol of the uplink control channel;
- wherein the uplink control channel is within a frequency sub-band that comprises a first partial sub-band with a sub-carrier spacing of 30 kHz and a second partial sub-band with a sub-carrier spacing of 60 kHz;
- wherein the first symbol is within the first partial sub-band with the sub-carrier spacing of 30 kHz;
- wherein the second symbol is within the second partial sub-band with the sub-carrier spacing of 60 kHz;
- the programming further including instructions to perform:
- receiving at the base station, further uplink data or control information using a third transmission resource in a third symbol of the uplink control channel, the third symbol within the second partial sub-band with the sub-carrier spacing of 60 kHz;
- wherein a time duration of the first symbol is twice a time duration of the second symbol and is twice a time duration of the third symbol;
- and
- wherein a start of the first symbol within the first partial sub-band is time aligned with a start of the second symbol within the second partial sub-band, and an end of the first symbol within the first partial sub-band is time aligned with an end of the third symbol within the second partial sub-band.
