Abstract
A method for small data transmission (SDT) in a power saving state is provided. The method includes applying at least one SDT related timer during the SDT on a first SDT bandwidth part (BWP) for the UE in the power saving state; and if the at least one SDT related timer is not running on the first SDT BWP, switching from the first SDT BWP to a second SDT BWP for receiving at least one of updated system information (SI) or public warning system (PWS) information from the network. With this method, monitoring SI change and/or PWS information on associated BWP during the SDT can achieved.
Claims20
A method for small data transmission (SDT) in a power saving state, performed by a user equipment (UE) in a network, the method comprising:
- applying at least one SDT related timer during the SDT on a first SDT bandwidth part (BWP) for the UE in the power saving state;
- if the at least one SDT related timer is not running on the first SDT BWP, switching from the first SDT BWP to a second SDT BWP for receiving at least one of updated system information (SI) or public warning system (PWS) information from the network;
- receiving at least one of a SI change indication or a PWS indication from the network before switching to the second SDT BWP;
- and
- upon reception of the at least one of the SI change indication or the PWS indication, no matter whether the at least one SDT related timer is running, switching from the first SDT BWP to the second SDT BWP for receiving the updated SI indicated by the SI change indication or receiving the PWS information indicated by the PWS indication.
A method for small data transmission (SDT) in a power saving state, performed by a base station (BS) in a network, the method comprising:
- configuring a user equipment (UE) with at least one SDT related timer for the UE to apply during the SDT on a first SDT bandwidth part (BWP) in the power saving state;
- and
- if the at least one SDT related timer is not running on the first SDT BWP, expecting the UE to switch from the first SDT BWP to a second SDT BWP for receiving at least one of updated system information (SI) or public warning system (PWS) information from the BS;
- transmitting at least one of a SI change indication or a PWS indication to the UE before the UE switches to the second SDT BWP;
- and
- upon transmission of the at least one of the SI change indication or the PWS indication, expecting the UE to switch, no matter whether the at least one SDT related timer is running, from the first SDT BWP to the second SDT BWP for receiving the updated SI indicated by the SI change indication or receiving the PWS information indicated by the PWS indication.
