Wireless device, a network node and methods therein for enabling and performing an uplink control channel transmission
First Claim
1. A method performed by a wireless device for performing an uplink control channel transmission in a serving cell in a wireless communications network when the wireless device is configured with a set of serving cells in the wireless communications network comprising the serving cell, the method comprisingdetermining a number of serving cells of the set of serving cells that are relevant to consider when performing the uplink control channel transmission in the serving cell, wherein the set of serving cells comprises at least one serving cell which is autonomously de-activated by the wireless device and which is not included in the number of serving cells that are relevant to consider;
- selecting an uplink control channel format from a set of uplink control channel formats for the uplink control channel transmission based on the determined number of serving cells; and
performing the uplink control channel transmission in the serving cell using the selected uplink control channel format;
wherein the number of serving cells that are relevant to consider when performing the uplink control channel transmission is determined based on one or more of the group consisting of;
the number of serving cells in the set of serving cells that the wireless device has been scheduled on; and
the serving cell in which the uplink control channel transmission is to be performed and one or more serving cells that are mapped to the serving cell in which the uplink control channel transmission into be performed.

Abstract
A method performed by a wireless device for performing an uplink control channel transmission in a serving cell in a wireless communications network is provided. The wireless device is configured with a set of serving cell(s) in the wireless communications network. First, the wireless device determines a number of serving cells of the set of serving cell(s) that are relevant to consider when performing the uplink control channel transmission in the serving cell. Secondly, the wireless device selects an uplink control channel format from a set of uplink control channel formats for uplink control channel transmissions based on the determined number of serving cells. Then, the wireless device performs the uplink control channel transmission in the serving cell using the selected uplink control channel format. A wireless device for performing an uplink control channel transmission in a serving cell in a wireless communications network is also provided.

8. A wireless device for performing an uplink control channel transmission in a serving cell in a wireless communications network when the wireless device is configured with a set of serving cells in the wireless communications network comprising the serving cell, wherein the wireless device is configured to:
-
determine a number of serving cells of the set of serving cells that are relevant to consider when performing the uplink control channel transmission in the serving cell, wherein the set of serving cells comprises at least one serving cell which is autonomously de-activated by the wireless device and which is not included in the number of serving cells that are relevant to consider; select an uplink control channel format from a set of uplink control channel formats for the uplink control channel transmission based on the determined number of serving cells; and perform the uplink control channel transmission in the serving cell using the selected uplink control channel format; wherein the number of serving cells that are relevant to consider when performing the uplink control channel transmission is determined based on one or more of the group consisting of; the number of serving cells in the set of serving cells that the wireless device has been scheduled on; and
the serving cell in which the uplink control channel transmission is to be performed and one or more serving cells that are mapped to the serving cell in which the uplink control channel transmission into be performed. - View Dependent Claims (9, 10, 11, 12, 13, 14)
