Method and apparatus for rapidly reporting frequency measurement results in next generation mobile communication system
摘要
說明書
The gNB may identify that the UE has performed early measurement and has measurement results to be reported through the indication in the Msg 5. In this case, the gNB may transmit a message that instructs the UE to report the measurement results to the UE in order to receive a fast measurement report at step 1f-50. For example, the gNB may request frequency measurement result information from the UE using UEinformationRequest through a DL-DCCH message. When the UE receives the message, the UE may make a fast measurement report to the gNB at step 1f-60. For example, when the UE receives the message, the UE may report frequency measurement results using measurementReport through the UL-DCCH message. The frequency measurement results may include serving cell/frequency measurement results (e.g., NR-SS RSRP), neighbor cell/frequency measurement results of a serving cell/frequency, neighbor cell/frequency measurement results that may be measured by the UE, and a cell/frequency measurement results indicated to be measured.
The conditions in which the UE may stop early measurement may include the following.
1. After transmitting the Msg 5,
2. After receiving a message or command indicative of a report on frequency measurement results from the gNB,
3. After configuring a message for reporting frequency measurement results to the gNB,
4. After transmitting a message for reporting frequency measurement results to the gNB,
5. When failing in random access, and
6. When the gNB explicitly instructs the UE to stop early measurement through an RRC. For example, the explicit instruction is indicated using an indication in the RRC Connection Setup message or RRC Connection Resume message.
