Abstract
A communication device for handling a narrowband internet of things (NB-IoT) communication comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise receiving a SystemInformationBlockType2-NB message broadcasted by a base station (BS) on an NB-IoT cell; receiving an RRCConnectionReconfiguration-NB message indicating a full configuration, from the BS on the NB-IoT cell; and using a plurality of values for timers T301, T310, T311 and constants N310, N311 in response to the RRCConnectionReconfiguration-NB message, wherein the values are comprised in the SystemInformationBlockType2-NB.
Claims2
A communication device for handling a narrowband internet of things (NB-IoT) communication, comprising:
- a storage device, for storing instructions of:
- receiving a SystemInformationBlockType2-NB message broadcasted by a base station (BS) on an NB-IoT cell;
- receiving an RRCConnectionReconfiguration-NB message indicating a full configuration, from the BS on the NB-IoT cell;
- using a plurality of values for timers T301, T310, T311, constant N310 for counting the number of consecutive “out-of-sync” indications for the NB-IoT cell, and constant N311 for counting the number of consecutive “in-sync” indications for the NB-IoT cell in response to the RRCConnectionReconfiguration-NB message, wherein the values are comprised in the SystemInformationBlockType2-NB;
- starting the timer T310, when detecting N310 consecutive “out-of-sync” indications for the NB-IoT cell;
- starting the timer T311, when the timer T310 expires;
- starting the timer T301, when the UE selects the NB-IoT cell while the timer T311 is running;
- and
- stopping the timer T310, when detecting N311 consecutive “in-sync” indications for the NB-IoT cell;
- and
- a processing circuit, coupled to the storage device, configured to execute the instructions stored in the storage device.
