US 2022/0070775 A1 · METHODS FOR UPDATING SYSTEM INFORMATION AND WIRELESS TRANSMIT/RECEIVE UNITS USING THEREOF

Abstract

A method for use in a Wireless Transmit/Receive Unit (WTRU). The method comprises: receiving, using an active receiver, system information comprising a first system information set, wherein the first system information set is currently valid for the WTRU; storing the system information; deactivating the active receiver and activating a passive receiver; determining whether a difference between a first parameter in the BSSI and a first parameter in the first system information set is greater than a threshold value, wherein on a condition that the difference is greater than the threshold value, reactivating the active receiver to receive a second system information set as a currently valid system information set for the WTRU.

Dependent claims

A method for updating system information by a Wireless Transmit/Receive Unit (WTRU), comprising:

receiving, using an active receiver, system information comprising a first system information set, wherein the first system information set is currently valid for the WTRU;
deactivating the active receiver and activating a passive receiver;
receiving a basic set of system information (BSSI) using the passive receiver;
and
reactivating the active receiver to receive a second system information set as a currently valid system information set for the WTRU based on a comparison of a threshold value with a difference between a parameter in the BSSI and a parameter in the first system information set.

A method for updating system information by a Wireless Transmit/Receive Unit (WTRU), comprising:

receiving, using an active receiver, system information comprising a plurality of system information sets, wherein a first system information set in the plurality of system information sets is currently valid for the WTRU, and each of the plurality of system information sets comprises a first parameter;
deactivating the active receiver and activating a passive receiver;
receiving a basic set of system information (BSSI) using the passive receiver;
and
reactivating the active receiver to receive a second system information set as a currently valid system information set for the WTRU based on a comparison of a threshold value with a difference between a parameter in the BSSI and a parameter in the first system information set.

2 more elements

A Wireless Transmit/Receive Unit (WTRU) for updating system information, comprising:

an active receiver configured to receive system information comprising a first system information set, wherein the first system information set is currently valid for the WTRU;
a passive receiver configured to receive a basic set of system information (BSSI);
a processor configured to deactivate the active receiver and activate the passive receiver after the active receiver receives the system information, and reactivate the active receiver to receive a second system information set as a currently valid system information set for the WTRU, based on a comparison of a threshold value with a difference between a parameter in the BSSI and a parameter in the first system information set.
