System and apparatus for indicating cell identifiers

摘要

The technology described relates to cell identifiers in which a cell provides two reporting cell identifiers for user equipments (UEs) taking cell measurements. In a non-limiting example embodiment, a secondary synchronization channel (S-SCH) is used to transmit two short cell identities. In this case, a cell uses two sets of signature sequences, one corresponding to the old reporting cell identifier and one corresponding to the new reporting cell identifier.

主权项

1. A method implemented in a radio transceiver served by a base station supporting a cell in a cellular radio communications network, comprising:
receiving a first signal transmitted by the serving base station, where the first signal indicates a first cell identifier for identifying the cell; performing measurement on the first signal to generate a first measurement signal; transmitting the first measurement signal to the serving base station; receiving a cell identifier message indicating a second cell identifier from the serving base station for identifying the cell; thereafter, receiving from the base station both the first signal indicating the first cell identifier and a second signal indicating the second cell identifier; performing measurement on the second signal to generate a second measurement signal; and transmitting the second measurement signal to the serving base station.
