Arrangements for measurement reports} - H04W: WIRELESS COMMUNICATION NETWORKS (broadcast communication H04H; communication systems using wireless links for non-selective communication, e.g. wireless extensions H04M1/72) ## Abstract The invention refers to a method in a user equipment, UE, for a measurement gap pattern configuration including receiving a configuration information indicative of a measurement gap pattern configuration, and a bandwidth part, BW, configuration, determining an association between measurement gap patterns and BW parts, receiving a message to change the active BW part to one of the configured BW parts, and changing the measurement gap pattern as a function of the corresponding BW part and the association; the invention further refers to a corresponding method in a network node; to corresponding UE, a corresponding network node, and computer programs. ## Claims ### Claim 1 A method in a user equipment, UE, for a measurement gap pattern configuration comprising: receiving a configuration information indicative of a measurement gap pattern configuration, and a bandwidth, BW, part configuration, determining an association between measurement gap patterns and BW parts, receiving a message to change the active BW part to one of the configured BW parts (81, 82), and changing the measurement gap pattern as a function of the corresponding BW part and the association. ### Claim 2 (depends on 1) The method of claim 1, further comprising: performing a gap measurement in a neighbor bandwidth of the active bandwidth part according to a gap pattern associated to the active BW part. ### Claim 3 (depends on 1) The method of claim 1, wherein the configuration information is received from a network node, e.g. a base station, gNB. ### Claim 4 (depends on 1) The method of claim 1, wherein the configuration information is comprised in one or a plurality of Radio Resource Control, RRC, messages. ### Claim 5 (depends on 1) The method of claim 1, wherein the message to change the active BW part is received from a network node, e.g. a base station, gNB. ### Claim 6 (depends on 1) The method of claim 1, wherein the message is a layer 1 message, e.g. a DCI message. ### Claim 7 (depends on 1) The method of claim 1, wherein the measurement gap patterns are characterized by at least one of: a periodicity, a gap length and a gap offset. ### Claim 8 (depends on 1) The method of claim 1, wherein the measurement gap patterns comprises at least one measurement gap pattern with gaps of zero length, implying that a neighbor measurement cell is measured without measurement gap. ### Claim 9 (depends on 1) The method of claim 1, wherein the BW part configuration comprises a first BW part and a second BW part, and wherein the first BW part is associated with a first measurement gap pattern with gaps being different from zero length, and the second BW part is associated with a second measurement gap pattern with gaps of zero length. ### Claim 10 (depends on 9) The method of claim 9, further comprising determining a threshold time (Td) to be applied for switching the measurement from the first measurement gap pattern to the second measurement gap pattern after switching the active BW part from the first BW part to the second BW part. ### Claim 11 (depends on 10) The method of claim 10, wherein the threshold time (Td) is determined based on one of: a pre-defined value; information received from a network node; measurement configuration information received from a network node. ### Claim 12 (depends on 1) The method of claim 1, wherein performing a gap measurement comprises switching off a receiver from the current active cell, tuning the receiver to another cell, performing a signal quality measurement, and after the measurement gap retuning the receiver to the current active cell. ### Claim 13 (depends on 1) The method of claim 1, wherein the association between the measurement gap patterns and the BW parts is received from the network node. ### Claim 14 (depends on 1) The method of claim 1, wherein the message to change the active BW part to one of the configured BW parts is received from the network node. ### Claim 15 A method in a network node, gNB, for a gap measurement configuration of a UE, comprising: transmitting a configuration information indicative of a measurement gap pattern configuration, and a bandwidth part, BW, configuration, determining an association between measurement gap patterns and BW parts, performing a communication with the UE according to the measurement gap pattern associated with the new active BW part in the UE. ### Claim 16 (depends on 15) The method of claim 15, further comprising transmitting to the UE an information indicative of the association of measurement gap patterns and BW parts. ### Claim 17 (depends on 15) The method of claim 15, further comprising: sending a message to the UE to change the active BW part to one of the configured BW parts. ### Claim 18 (depends on 15) The method of claim 15, wherein the BW part configuration comprises a first BW part and a second BW part, and wherein the first BW part is associated with a first measurement gap pattern with gaps being different from zero length, and the second BW part is associated with a second measurement gap pattern with gaps of zero length, further comprising sending to the UE a threshold time (Td) to be applied for switching the measurement from the first measurement gap pattern to the second measurement gap pattern after switching the active BW part from the first BW part to the second BW part. ### Claim 19 (depends on 15) The method of claim 15, wherein the configuration information is comprised in one or a plurality of Radio Resource Control, RRC, messages. ### Claim 20 (depends on 15) The method of claim 15, wherein the message to change the active BW part is a layer 1 message, e.g. a downlink control information, DCI, message. ### Claim 21 (depends on 1) A user equipment, UE, adapted to perform the method of claim 1. ### Claim 22 (depends on 1) A user equipment, UE, comprising: a processor; and a memory storing instructions which, when executed by the processor, cause the processor to perform the method of claim 1. ### Claim 23 (depends on 1) A non-transitory computer readable storage medium having instructions stored thereon, which, when executed by a processor, cause the processor to perform the method of claim 1. ### Claim 24 (depends on 16) A network node, gNB, adapted to perform the method of claim 16. ### Claim 25 (depends on 16) A network node, gNB, comprising: a processor; and a memory storing instructions which, when executed by the processor, cause the processor to perform the method of claim 16. ### Claim 26 (depends on 16) A non-transitory computer readable storage medium having instructions stored thereon, which, when executed by a processor, cause the processor to perform the method of claim 16.
