Providing identities of secondary cells to apparatus for discovery in a physical discovery channel

摘要

A primary cell (PCell) configures 40 a physical discovery channel (PDCH) for a plurality of secondary cells (SCells). The configuring may include interference management among the SCells and coordinating transmission periodicity of the PDCH transmitted by the configured SCells. The primary cell (PCell) provides 42 individual identities of the secondary cells (SCells) to user equipment (UE) for discovery in the PDCH of at least one secondary cell (SCell) using at least one of the provided individual identities. The primary cell (PCell) may receive 44 from the user equipment (UE) a report of discovery of the at least one secondary cell (SCell). The primary cell (PCell) may configure 46 the at least one secondary cell (SCell) for transmitting additional data to the user equipment (UE) on a secondary carrier to provide carrier aggregation (CA) of the secondary carrier with a primary carrier of the primary cell (PCell).
