Definitions

  • Evolved UTRAN is an evolution of the UTRAN towards a high-data rate, low-latency and packet-optimised radio access network. Further, the E-UTRAN consists of radio base stations
  • the case when the eNB issues a Layer 1 MIMO reconfiguration is considered, where a UE is currently configured to receive the Physical Downlink Shared Channel (PDSCH) with e.g. transmit diversity, but the desire is to reconfigure PDSCH to spatial multiplexing.
  • PDSCH Physical Downlink Shared Channel
  • a UE configured to one of a set of available MIMO schemes will not be able to receive PDSCH if the transmitter (eNB) is using a different scheme.
  • the reconfiguration of the PDSCH is asynchronous, there is a risk that the connectivity between the UE and the eNB is lost.
  • the radio base station detects that the UE responds to requests, which included the additional UE identity, the radio base station can conclude that the UE has activated the new configuration.
  • a method in a radio base station for activating a radio resource reconfiguration in a UE and in the radio base station is provided such that the radio base station can conclude when the UE is ready to start the new configuration.
  • the UE being subject to the reconfiguration is identifiable by a first UE identity.
  • a reconfiguration message is sent indicating a new configuration to be used by said UE and the reconfiguration message comprises a second UE identity for said UE.
  • the second UE identity is associated with said new configuration.
  • the new configuration is activated and an indication that the UE is identifiable by the second UE identity is received. When the indication that the UE is identifiable by the second UE identity is received, the UE is ready to start transmission or reception with the new configuration.
  • embodiments of the present invention relates to a radio base station 601 (e.g. an eNB) and to a UE 600 as illustrated in figure 6.
  • the UE being subject to the reconfiguration is identifiable by a first UE identity.
  • the radio base station comprises a transmitter 602 for sending a reconfiguration message indicating a new configuration to be used by said UE, wherein the reconfiguration message comprises a second UE identity for said UE and the second UE identity is associated with said new configuration.
  • the radio base station comprises further a processing unit 604 for activating the new configuration.
  • the UE comprises a receiver 605 for receiving the reconfiguration message.
  • the UE comprises a processing unit 606 for activating the new configuration, and a transmitter 607 for indicating to the radio base station that the UE is identifiable by the second UE identity since it has activated the new configuration.
  • the radio base station comprises further a receiver 603 for receiving an indication that the UE is identifiable by the second UE identity and the processing unit 604 for determining that the UE is ready to use the new configuration when the indication that the UE is identifiable by the second UE identity is received.
  • the reconfiguration comprises a request to the UE to perform a UE initiated procedure in association with the reconfiguration.
  • the processing unit 606 of the UE is configured to initiate the UE initiated procedure in association with the reconfiguration and the receiver 603 of the radio base station is configured to detect that the UE initiated procedure is initiated.
