Abstract
Network Node, NN, (500, 202, 302) and User Equipment, UE, (700, 201, 301) and methods therein, for changing a state of transmission time interval, TTI, Bundling. The method in a NN involves determining whether a transmission time interval, TTI, Bundling setting of the UE should be changed from one state to the other of a state ON and a state OFF. When it is decided (402) that the TTI Bundling setting of the UE should be changed, a message is transmitted to the UE, indicating the decided change of TTI Bundling setting. Further, as a consequence of the decision to change the TTI Bundling setting, and in association with the transmission of the message, mobility control information is transmitted to the UE, indicating the cell A as target cell, in order to cause the UE to perform an intra-cell hand over procedure.

23. A method performed by a network node serving a User Equipment, UE, in a cell, said method comprising:
-
determining whether a transmission time interval, TTI, Bundling setting of the UE should be changed from one state to the other of a state ON and a state OFF; and when it is decided that the TTI Bundling setting of the UE should be changed; transmitting, a message to the UE, indicating the decided change of TTI Bundling setting; and in association with the transmission of the message, transmitting mobility control information to the UE, indicating the cell as a target cell, to cause the UE to perform an intra-cell hand over procedure. - View Dependent Claims (24, 25, 26, 27, 28, 29)

30. A network node operable to serve a User Equipment, UE, in a cell, said network node comprising:
-
a communication transceiver configured for communicating with the UE; and a processor circuit operatively associated with the communication transceiver and configured to; determine whether a transmission time interval, TTI, Bundling setting of the UE should be changed from one state to the other of a state ON and a state OFF; transmit a message to the UE when it is decided that the TTI Bundling setting of the UE should be changed, said message indicating the decided change of TTI Bundling setting; and transmit mobility control information to the UE, as a consequence of the decision to change the TTI Bundling setting and in association with the transmission of the message, wherein the mobility control information indicates the cell as a target cell, to cause the UE to perform an intra-cell hand over procedure. - View Dependent Claims (31, 32, 33, 34, 35, 36)

37. A method performed by a User Equipment, UE, served by a network node in a cell, the method comprising:
-
receiving a message from the network node indicating that a Transmission Time Interval, TTI, Bundling setting of the UE should be changed from one state to the other of a state ON and a state OFF; determining whether mobility control information is received in association with the message, said mobility control information indicating the cell as target cell; determining which type of Random Access to be used for a Random Access procedure towards the target cell; and applying the changed TTI Bundling setting to transmissions to the network node in accordance with the determined Random Access procedure. - View Dependent Claims (38)

41. A non-transitory computer-readable medium storing a computer program, comprising computer readable code modules that when executed on a processing circuit of a User Equipment, UE, configured for operation in a communication network, configures the UE to:
-
receive a message from the network node, indicating that a Transmission Time Interval, TTI, Bundling setting of the UE should be changed from one state to the other of a state ON and a state OFF; determine whether mobility control information is received in association with the message, said mobility control information indicating a target cell; determine which type of Random Access to use for a Random Access procedure towards the target cell; and apply the changed TTI Bundling setting to transmissions to the network node in accordance with the determined Random Access procedure.

42. A non-transitory computer-readable medium storing a computer program, comprising computer readable code modules that, when executed on a processing circuit of a network node configured for operation in a communication network, configures the network node to:
-
determine whether a transmission time interval, TTI, Bundling setting of a User Equipment, UE, operating in the network should be changed from one state to the other of a state ON and a state OFF; and when it is decided that the TTI Bundling setting of the UE should be changed, transmit, a message to the UE, indicating the decided change of TTI Bundling setting, and, in association with the transmission of the message, transmit mobility control information to the UE, indicating a target cell, in order to cause the UE to perform an intra-cell hand over procedure.
