Embodiment Construction

[0033] As part of presenting the examples herein, the issues will first be specified and discussed.

[0034] In order to increase the peak rate in the technology, multi-carrier or carrier aggregation solutions are known. For example, multiple 5 MHz carriers can be used in High Speed ​​Packet Data Access (HSPA) to increase the peak rate in the HSPA network. Similarly, for example, in LTE, multiple 20MHz carriers or even smaller carriers (eg, 5MHz) may be aggregated in the UL and / or in the DL. Each carrier in a multi-carrier or carrier aggregation system is usually called a component carrier (CC) or sometimes a cell. In short, CC refers to a single carrier in a multi-carrier system. The term carrier aggregation (CA) is also referred to (eg, interchangeably) as "multi-carrier system", "multi-cell operation", "multi-carrier operation", "multi-carrier" transmission and / or reception. This means that CA is used to send signaling and data in uplink and downlink direction. One of t...

Abstract

A method in a network node for adapting a Secondary cell, SCell, command to a user equipment, UE, is provided. The SCell command is one of a setup and release command. The network node adapts the SCell command by one of advancing and delaying the timing of sending said SCell command with respect to a start of a transmission occasion of disjoint signals on which one of the UE and the network node is performing at least one of a measurement, the disjoint signal is a signal that is not used for performing the measurement in every subframe, a data transmission, the disjoint signal is a signal that is not used for transmitting the data in every subframe, and a data reception, the disjoint signal is a signal that is not used for receiving the data reception in every subframe.

Description

technical field [0001] Embodiments herein relate to network nodes, user equipment and methods therein. In particular, embodiments herein relate to adapting Secondary Cell (SCell) commands to UEs and to adjusting SCell setup or release. Background technique [0002] Wireless mobile communication networks are ubiquitous in many parts of the world. As technology evolves, network capacity, speed, bandwidth, latency, flexibility, and overall complexity continue to improve. This results in a series of versions or revisions of the technical specification for a given protocol or access technology, each version adding features such as advanced modes of operation (e.g. discontinuous operation for power saving), multiple antennas, multiple carriers, different duplex modes, etc. [0003] An advanced feature of many third-generation wireless communication protocols is the specification of multiple signal carrier frequencies, or "carriers," which is known in the art as carrier aggregat...
