## Abstract

The present disclosure provides a method in a wireless device, for handling spatial relations for Physical Uplink Control Channel (PUCCH) resources belonging to different PUCCH groups or PUCCH resource configuration groups. The method comprises: receiving, from a network node, a command to activate or deactivate a spatial relation for a PUCCH resource, wherein each PUCCH of the different PUCCH groups is uniquely identified in the command; and performing one of activating and deactivating a spatial relation for the PUCCH resource identified in the command. A wireless device for implementing this method is also provided.

## Claims

### Claim 1

A method in a wireless device, for handling spatial relations for Physical Uplink Control Channel (PUCCH) resources belonging to different PUCCH configuration groups, the method comprising:
receiving, from a network node, a command to activate or deactivate a spatial relation from a set of spatial relations, for a PUCCH resource indicated by a PUCCH resource Identifier (ID), wherein each PUCCH resource in the different PUCCH configuration groups is uniquely identified in the command, by using a PUCCH resource ID that is different for each PUCCH configuration group; and
performing one of activating and deactivating the spatial relation for the PUCCH resource indicated in the command.

### Claim 2 (depends on 1)

The method of claim 1, wherein receiving the command comprises receiving a Medium Access Control (MAC) Control Element (CE).

### Claim 3 (depends on 1)

The method of claim 1, wherein PUCCH resources of a first PUCCH configuration group is concatenated with PUCCH resources of a second PUCCH configuration group.

### Claim 4 (depends on 1)

The method of claim 1, wherein the command comprises a PUCCH spatial relation for a plurality of PUCCH resources.

### Claim 5 (depends on 4)

The method of claim 4, wherein the plurality of PUCCH resources belong to different PUCCH configuration groups.

### Claim 6 (depends on 4)

The method of claim 4, wherein the command comprises a group ID, the group ID identifying the plurality of PUCCH resources to which the same PUCCH spatial relation is applied.

### Claim 7 (depends on 1)

The method of claim 1, wherein each PUCCH resource ID indicates a PUCCH configuration group to which the PUCCH resource belongs to.

### Claim 8 (depends on 1)

The method of claim 1, wherein the set of spatial relations is associated with a PUCCH configuration group.

### Claim 9 (depends on 1)

The method of claim 1, wherein the set of spatial relations is associated with a PUCCH configuration group to which the indicated PUCCH resource ID belongs.

### Claim 10

(canceled)

### Claim 11

(canceled)

### Claim 12

A user equipment (UE) configured to communicate with a base station, the UE comprising a radio interface and processing circuitry configured to:
receive, from a network node, a command to activate or deactivate a spatial relation from a set of spatial relations, for a PUCCH resource indicated by a PUCCH resource Identifier (ID), wherein each PUCCH resource in the different PUCCH configuration groups is uniquely identified in the command, by using a PUCCH resource ID that is different for each PUCCH configuration group; and
perform one of activating and deactivating the spatial relation for the PUCCH resource indicated in the command.

### Claim 13

A method in a network node, for indicating spatial relations for Physical control channel (PUCCH) resources belonging to different PUCCH configuration groups to a wireless device, the method comprising:
determining a PUCCH configuration group to which a PUCCH resource belongs; and
sending, to the wireless device, a command to activate or deactivate a spatial relation from a set of spatial relations for the PUCCH resource, indicated by a PUCCH resource Identifier (ID), wherein each PUCCH resource in the different PUCCH configuration groups is uniquely identified in the command, by using a PUCCH resource ID that is different for each PUCCH configuration group.

### Claim 14 (depends on 13)

The method of claim 13, wherein sending the command comprises sending a Medium Access Control (MAC) Control Element (CE).

### Claim 15 (depends on 13)

The method of claim 13, wherein PUCCH resources of a first PUCCH configuration group is concatenated with PUCCH resources of a second PUCCH configuration group.

### Claim 16 (depends on 13)

The method of claim 13, wherein the command comprises a PUCCH spatial relation for a plurality of PUCCH resources.

### Claim 17 (depends on 16)

The method of claim 16, wherein the plurality of PUCCH resources belong to different PUCCH configuration groups.

### Claim 18 (depends on 16)

The method of claim 16, wherein the command comprises a group ID, the group ID identifying the plurality of PUCCH resources to which the same PUCCH spatial relation is applied.

### Claim 19 (depends on 13)

The method of claim 13, wherein each PUCCH resource ID indicates a PUCCH configuration group to which the PUCCH resource belongs to.

### Claim 20 (depends on 13)

The method of claim 13, wherein the set of spatial relations is associated with a PUCCH configuration group.

### Claim 21 (depends on 13)

The method of claim 13, wherein the set of spatial relations is associated with a PUCCH configuration group to which the indicated PUCCH resource ID belongs.
