Wireless communication device, a network node and methods therein for improved random access
First Claim
1. A method for reducing a delay to configure a secondary cell in dual connectivity performed by a communication device in a radio communications network, the communication device is capable of dual connectivity in a first cell of a first network node and at least a second cell of at least a second network node, the method comprising:
- obtaining information indicating a first random access channel configuration used in the first cell;
obtaining information indicating at least a second random access channel configuration used in the at least second cell; and
determining the time required by the communication device to configure the at least second cell based on whether the at least second random access channel configuration is orthogonal to the first random access channel configuration.

Abstract
Embodiments herein relate to a communication device and a method performed by the communication device for enabling improved random access transmissions in a radio communications network. The communication device obtains information indicating a first random access channel configuration and also obtains information indicating at least a second random access channel configuration. Then, the communication device determine whether or not the at least second random access channel configuration is orthogonal to the first random access channel configuration. Furthermore, the communication device uses the result of the determining to determine the time required by the communication device to configure the at least second cell. Embodiments herein also relate to a first network node and a method therein for enabling improved random access transmissions in a radio communications network.
