Abstract
Embodiments herein relate to a user equipment, UE, configured to performing measurements in a wireless communication network. The UE acquires system information, SI, of a cell during autonomous gaps, and also performs at least one non-SI measurement related to a serving and/or to one or more neighbour cells during a time period comprising the autonomous gaps. The embodiments also relate to a serving network node, a target network node and respective method therein.
Claims40
A method in a User Equipment, UE, for performing measurements in a wireless communication network, the method comprising:
- acquiring system information, SI, of a cell during autonomous gaps created by the UE, and
- performing at least one non-SI measurement related to a serving and/or to one or more neighbour cells during a time period comprising said autonomous gaps.
A method in a serving network node for configuring measurements performed by a user equipment, UE, comprising:
- requesting the UE to acquire system information, SI, of a cell during autonomous gaps created by the UE, and
- scheduling non-SI measurement subframes in order to avoid collision between the non-SI measurement subframes and the UE created autonomous gaps.
A method in a target network node for enabling a User Equipment, UE, to acquire System Information, SI, wherein the target network node associated to a cell from which the UE is requested to acquire the SI is any one of:
- an UTRAN network node, E-UTRAN network node, GSM network node, CDMA2000 network node or multi-standard radio base station, the method comprises:
- receiving information that the UE is attempting to acquire a System Information Block, SIB, and determining to minimise the impact of SIB scheduling on SI acquisition for the UE by:
- using a single or a minimum number of segments to transmit the SIB, wherein if more than one segment is used to transmit the SIB, then transmitting the segments at System Frame Number, SFN, offsets that enable the UE to catch up non-SI measurements in between, and/or
- using a SIB repetition period that enables the UE to catch up non-SI measurements in between reception of the SIB or segments thereof.
A User Equipment, UE, adapted to perform measurements in a wireless communication network, the UE comprising an acquisition unit adapted to:
- acquire system information, SI, of a cell during autonomous gaps created by the UE, and
- perform at least one non-SI measurement related to a serving and/or to one or more neighbour cells during a time period comprising said autonomous gaps.
A serving network node adapted to configure measurements performed by a user equipment, UE, the serving network node comprising:
- a requesting unit adapted to request the UE to acquire system information, SI, of a cell during autonomous gaps created by the UE, and
- a scheduler adapted to schedule non-SI measurement subframes in order to avoid collision between the non-SI measurement subframes and the UE created autonomous gaps.
A target network node adapted to enable a User Equipment, UE, to acquire System Information, SI, wherein the target network node associated to a cell from which the UE is requested to acquire the SI is any one of:
- an UTRAN network node, E-UTRAN network node, GSM network node, CDMA2000 network node or multi-standard radio base station, the target network node comprising a receiving unit adapted to receive information that the UE is attempting to acquire a System Information Block, SIB, and the target network node comprising a processing unit adapted to determine to minimise the impact of SIB scheduling on SI acquisition for the UE by:
- using a single or a minimum number of segments to transmit the SIB, wherein if more than one segment is used to transmit the SIB, then the processing unit is adapted to transmit the segments at System Frame Number, SFN, offsets that enable the UE to catch up non-SI measurements in between, and/or
- using a SIB repetition period that enables the UE to catch up non-SI measurements in between reception of the SIB or segments thereof.
