Methods and devices for cell discovery

摘要

This disclosure sets forth methods and devices for communication between mobile devices and base stations with active and dormant states. In an embodiment, a base station transmits system information during an active state of the base station with at least one system-information message. The at least one system-information message includes a SystemInformationBlockType1 (“SIB1”) message with a first update-indicator field. The base station selects an update value that indicates whether the system information has changed since a previous transmission of a previous SIB1 message. The base station transmits at least one dormant-state message during a dormant state of the base station with the selected update value in a second update-indicator field of the at least one dormant-state message.

主权项

1. A method in a base station for a long term evolution network, the method comprising:
transmitting, during an active state of the base station, system information with at least one system-information message, wherein the at least one system-information message comprises a SystemInformationBlockType1 (“SIB1”) message with a first update-indicator field; selecting an update value that indicates whether the system information has changed since a previous transmission of a previous SIB1 message; and transmitting, during a dormant state of the base station, at least one dormant-state message with the selected update value in a second update-indicator field of the at least one dormant-state message.
