Determination of subframe type for subframes containing discovery signals

An apparatus for wireless communication, comprising:

• means for determining a time division duplex (TDD) configuration and a multicast-broadcast single-frequency network (MBSFN) configuration of a serving cell;
• means for receiving a two-bit neighbor cell configuration information indicating at least one of a TDD configuration and an MBSFN configuration of one or more neighboring cells relative to the TDD configuration and MBSFN configuration of the serving cell;
• means for receiving a configuration of a discovery reference signal (DRS) for at least one of the one or more neighboring cells, wherein the configuration comprises at least a starting subframe index for the DRS;
• and
• means for determining whether a common reference signal (CRS) is present in one or more subframes of a duration of the DRS for the at least one of the one or more neighboring cells based on the received two-bit neighbor cell configuration information, the TDD configuration and the MBSFN configuration of the serving cell, and the starting subframe index for the DRS.

An apparatus for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determine a time division duplex (TDD) configuration and a multicast-broadcast single-frequency network (MBSFN) configuration of a serving cell;
• receive a two-bit neighbor cell configuration information indicating at least one of a TDD configuration and an MBSFN configuration of one or more neighboring cells relative to the TDD configuration and MBSFN configuration of the serving cell;
• receive a configuration of a discovery reference signal (DRS) for at least one of the one or more neighboring cells, wherein the configuration comprises at least a starting subframe index for the DRS;
• and
• determine whether a common reference signal (CRS) is present in one or more subframes of a duration of the DRS for the at least one of the one or more neighboring cells based on the received two-bit neighbor cell configuration information, the TDD configuration and the MBSFN configuration of the serving cell, and the starting subframe index for the DRS.

• determining a time division duplex (TDD) configuration and a multicast-broadcast single-frequency network (MBSFN) configuration of a serving cell;
• receiving a two-bit neighbor cell configuration information indicating at least one of a TDD configuration and an MBSFN configuration of one or more neighboring cells relative to the TDD configuration and MBSFN configuration of the serving cell;
• receiving a configuration of a discovery reference signal (DRS) for at least one of the one or more neighboring cells, wherein the configuration comprises at least a starting subframe index for the DRS;
• and
• determining whether a common reference signal (CRS) is present in one or more subframes of a duration of the DRS for the at least one of the one or more neighboring cells based on the received two-bit neighbor cell configuration information, the TDD configuration and the MBSFN configuration of the serving cell, and the starting subframe index for the DRS.
