Abstract

A method of operating a wireless device in a wireless communication network, the wireless device being triggered for transmission of first information utilising a first resource structure and being associated to a first transmission quality, the wireless device also being triggered for transmission of second information utilising a second resource structure and being associated to a second transmission quality, the first resource structure and the second resource structure overlapping at least partly in time, the method including transmitting the first information and the second information utilising a common resource structure if the common resource structure and/or the transmission utilising the common resource structure ends or is expected to end in time before a time domain end of a predetermined time window. The disclosure also pertains to related devices and methods.

First claim

The invention claimed is:

1 . A method of operating a wireless device in a wireless communication network, the wireless device being triggered for transmission of first information utilising a first resource structure and being associated to a first transmission quality, the wireless device also being triggered for transmission of second information utilising a second resource structure and being associated to a second transmission quality, the first resource structure and the second resource structure overlapping at least partly in time, the method comprising:
transmitting the first information and the second information utilising a common resource structure that is different from the first resource structure and the second resource structure if at least one of the common resource structure and the transmission utilising the common resource structure one of ends and is expected to end in time before a time domain end of a predetermined time window, the predetermined time window spanning at least one of a time interval and a number N of symbols corresponding to a time interval equal to or smaller than a slot duration.

2 . The method according to claim 1 , wherein the first transmission quality and the second transmission quality correspond to at least one of different service requirements and priorities.

3 . The method according to claim 1 , wherein the common resource structure comprises more resource elements than at least one of the first resource structure and the second resource structure.

4 . The method according to claim 1 , wherein at least one of:
the first information is uplink control information; and the second information is uplink control information.

5 . The method according to claim 1 , wherein the predetermined time window starts one of at a beginning and at an end of a received transmission.

6 . The method according to claim 1 , wherein, if the at least one of the common resource structure and transmission utilising the common resource structure one of does not end and is not expected to end before the time domain end of the predetermined time window, only one of the first information and second information is transmitted before the time domain end of the predetermined time window.

7 . The method according to claim 1 , wherein a duration of the predetermined time window is at least one of:
dependent on at least one of a transmission type and priority of one of the first information and second information; and associated to the one of the first resource structure and second resource structure.

8 . The method according to claim 1 , wherein the transmission utilising the common resource structure is according to one of the first transmission type and second transmission type.

9 . A wireless device for a wireless communication network, the wireless device configured to:
be one of triggered and triggerable for transmission of first information utilising a first resource structure and being associated to a first transmission quality; be one of triggered and triggerable for transmission of second information utilising a second resource structure and being associated to a second transmission quality; the first resource structure and the second resource structure overlapping at least partly in time; and transmit the first information and the second information utilising a common resource structure that is different from the first resource structure and the second source resource structure where at least one of the common resource structure and the transmission utilising the common resource structure one of ends and is expected to end in time before a time domain end of a predetermined time window, the predetermined time window spanning at least one of a time interval and a number N of symbols corresponding to a time interval equal to or smaller than a slot duration.

10 . A method of operating a network node in a wireless communication network, the method comprising:
receiving, from a wireless device, signaling on a resource structure, the wireless device being triggered for transmission of first information utilising a first resource structure and being associated to a first transmission quality, the wireless device also being triggered for transmission of a second information utilising a second resource structure and being associated to a second transmission quality; the first resource structure and the second resource structure overlapping at least partly in time; and the signaling is received on a common resource structure that is different from the first resource structure and the second resource structure and represent the first information and the second information if at least one of the common resource structure and the signaling on the common resource structure one of ends and is expected to end in time before a time domain end of a predetermined time window, the predetermined time window spanning at least one of a time interval and a number N of symbols corresponding to a time interval equal to or smaller than a slot duration.

11 . The method according to claim 10 , wherein the first transmission quality and the second transmission quality correspond to at least one of different service requirements and priorities.

12 . The method according to claim 10 , wherein the common resource structure comprises more resource elements than at least one of the first resource structure and the second resource structure.

13 . The method according to claim 10 , wherein at least one of:
the first information is uplink control information; and the second information is uplink control information.

14 . The method according to claim 10 , wherein the predetermined time window starts one of at a beginning and at an end of a received transmission.

15 . A network node for a wireless communication network, the network node configured to:
receive, from a wireless device, signaling on a resource structure, the wireless device being triggered for transmission of first information utilising a first resource structure and being associated to a first transmission quality, the wireless device also being triggered for transmission of a second information utilising a second resource structure and being associated to a second transmission quality; the first resource structure and the second resource structure overlapping at least partly in time; and the signaling is received on a common resource structure that is different from the first resource structure and the second resource structure and represent the first information and the second information if at least one of the common resource structure and the signaling on the common resource structure one of ends and is expected to end in time before a time domain end of a predetermined time window, the predetermined time window spanning at least one of a time interval and a number N of symbols corresponding to a time interval equal to or smaller than a slot duration.

16 . A non-transitory computer storage medium comprising instructions configured to cause processing circuitry to at least one of control and perform a method of operating a wireless device in a wireless communication network, the wireless device being triggered for transmission of first information utilising a first resource structure and being associated to a first transmission quality, the wireless device also being triggered for transmission of second information utilising a second resource structure and being associated to a second transmission quality, the first resource structure and the second resource structure overlapping at least partly in time, the
