Apparatuses, methods and computer programs for a mobile transceiver and a base station transceiver, mobile transceiver, base station transceiver and mobile communication system

摘要

Embodiments provide apparatuses, methods and computer programs for a mobile transceiver and a base station transceiver, a mobile transceiver, a base station transceiver and a mobile communication system. The apparatus for the mobile transceiver in a mobile communication system comprises means for receiving information on a periodic measurement configuration for an inter-frequency measurement from a base station transceiver of the mobile communication system on a first frequency layer. The inter-frequency measurement refers to a repetitive measurement on a second frequency layer with a repetition cycle, which is such that the mobile transceiver , when moving at a velocity below a velocity threshold, is located in a coverage area of another base station transceiver on the second frequency layer for at least two repetition cycles.

主权项

1. A user equipment for wireless communication in a mobile communication system, comprising:
a receiver configured to receive information from a macrocell base station of a mobile communication system on a first frequency layer, wherein the information includes a periodic measurement configuration identifying a repetition cycle for inter-frequency measurements for a second frequency layer used by a smaller cell base station when a coverage area formed by the smaller cell base station is within a coverage area formed by the macrocell base station, wherein the repetition cycle is such that, when the user equipment moves at a velocity below a velocity threshold through a central portion of the coverage area of the smaller cell base station, the user equipment makes inter-frequency measurements for at least two repetition cycles while the user equipment was within the coverage area of the smaller cell base station; at least one processor configured to perform the inter-frequency measurements in accordance with the repetition cycle associated with the periodic measurement configuration, the inter-frequency measurements including a signal measurement of a radio signal from the smaller cell base station on the second frequency layer while the user equipment moved through the coverage area of the smaller cell base station, wherein the signal measurement is indicative of a signal quality of the corresponding radio signal; and a transmitter configured to report information on the inter-frequency measurements to the macrocell base station on the first frequency layer, wherein the information on the inter-frequency measurements is reported when the signal quality represented by the signal measurement is greater than a reporting threshold such that the transmitter avoids reporting information on inter-frequency measurements when the signal quality represented by the signal measurement is not greater than the reporting threshold; wherein the information carrying the periodic measurement configuration comprises information on repetitive time windows; wherein the macrocell base station is configured to adapt a duration of the time windows such that, when the user equipment moves slower than the velocity threshold through a cell formed by the smaller cell base station, wherein the at least one processor is configured to perform at least two inter-frequency measurements when moving along a straight line through a center of the cell and configured to perform a single measurement when moving along a straight line through the center of the cell faster than the velocity threshold.
