System access for heterogeneous networks

A user equipment (UE) configured for wireless communication for acquiring control information for performing a Random Access Channel Procedure (RACH) at the UE, comprising:

• means for obtaining resource scheduling information for an access point of a weak cell from a transmission transmitted by another access point of at least one other cell of a plurality of neighboring cells, said at least one other cell being barred from access by said UE, said weak cell being one of said plurality of neighboring cells and not having a strongest signal from among said plurality of neighboring cells at said UE, and said transmission containing the resource scheduling information for a broadcast transmission from the weak cell;
• means for identifying broadcasted system blocks from said weak cell using said resource scheduling information;
• means for retrieving control information from said broadcasted system blocks;
• means for performing the RACH procedure with the weak cell based on said control information;
• and
• means for determining that the at least one other cell is barred from access by said UE,
• wherein said means for obtaining resource scheduling information for said access point of said weak cell is responsive to said means for determining that the at least one other cell is barred from access by said UE.

A computer program product for wireless communications in a wireless network for acquiring control information for performing a Random Access Channel Procedure (RACH) at a user equipment (UE), comprising:

• a non-transitory computer-readable medium having program code recorded thereon, that when executed a processor, cause the processor to:
• program code to obtain resource scheduling information for an access point of a weak cell from a transmission transmitted by another access point of at least one other cell of a plurality of neighboring cells, said at least one other cell being barred from access by said UE, said weak cell being one of said plurality of neighboring cells and not having a strongest signal from among said plurality of neighboring cells at said UE, and said transmission containing the resource scheduling information for a broadcast transmission from the weak cell;
• program code to identify broadcasted system blocks from said weak cell using said resource scheduling information;
• program code to retrieve control information from said broadcasted system blocks;

• at least one processor;
• and
• a memory coupled to said at least one processor,
• wherein said at least one processor is configured to:
• obtain resource scheduling information for an access point of a weak cell from a transmission transmitted by another access point of at least one other cell of a plurality of neighboring cells, said at least one other cell being barred from access by said UE, said weak cell being one of said plurality of neighboring cells and not having a strongest signal from among said plurality of neighboring cells at said UE, and said transmission containing the resource scheduling information for a broadcast transmission from the weak cell;

A method of wireless communication for acquiring control information for performing a Random Access Channel Procedure (RACH) at a user equipment (UE), comprising:

• decoding, by the UE, system information blocks transmitted by an access point of a strong cell to obtain sub frame partition information useful to identify system information blocks transmitted by another access point of a weak cell, said strong cell being barred from access by said UE, wherein the strong cell is a neighbor of the weak cell and a signal of the strong cell at the UE is stronger than a signal of the weak cell at the UE;
• using the subframe partition information, by the UE, to identify the system information blocks transmitted by the other access point of the weak cell;
• decoding, by the UE, the system information blocks transmitted by the weak cell to retrieve control information;
• using the control information, by the UE, to complete initial random access to the weak cell;
• and
• determining, by the UE, that said strong cell is barred from access by said UE,
• wherein said decoding, by the UE, system information blocks transmitted by said access point of said strong cell to obtain sub frame partition information is performed in response to said determining, by the UE, that said strong cell is barred from access by said UE.
