Providing a system information block request and response

A method of wireless communication operable at an access network comprising a plurality of base stations, the method comprising:

• transmitting a master information block (MIB) comprising configuration information for a first cell of the access network;
• transmitting a discovery reference signal, the discovery reference signal comprising at least one of a primary reference signal, a secondary reference signal, a cell-specific reference signal, or a combination thereof;
• receiving a chirp signal from a user equipment (UE) as part of a random access procedure to establish a connection between the UE and the first cell, the chirp signal comprising at least one of a reference signal, a pilot signal, a UE identifier, a buffer status report, or a combination thereof, the chirp signal being configured as a system information request that specifies at least one system information block requested by the UE;
• selecting one or more of the at least one system information block requested by the UE;
• and
• transmitting, in a unicast radio resource control (RRC) message, a system information response to the UE in response to the chirp signal, wherein the system information response comprises the one or more of the at least one system information block requested by the UE scrambled with a serving cell identifier.

A user equipment (UE), comprising:

• a communication interface configured to communicate with an access network;
• a memory;
• and
• one or more processors operatively coupled to the communication interface and the memory, the one or more processors and the memory configured to:
• receive a master information block (MIB) from an access network, the MIB comprising configuration information for a first cell of the access network;
• receive a discovery reference signal from the access network, the discovery reference signal comprising at least one of a primary reference signal, a secondary reference signal, a cell-specific reference signal, or a combination thereof;
• select the first cell of the access network utilizing information in the MIB and information contained in the discovery reference signal;
• transmit a chirp signal to the access network as part of a random access procedure to establish a connection with the first cell, the chirp signal comprising at least one of a reference signal, a pilot signal, a UE identifier, a buffer status report, or a combination thereof, the chirp signal being configured as a system information request that specifies at least one system information block requested by the UE;
• and
• receive, in a unicast radio resource control (RRC) message, a system information response transmitted in response to the chirp signal, wherein the system information response comprises one or more of the at least one system information block requested by the UE scrambled with a serving cell identifier.

An access network node comprising:

• a communication interface configured to communicate with a user equipment (UE);
• a memory comprising executable code;
• and
• one or more processors operatively coupled to the communication interface and the memory, the one or more processors and the memory configured to:
• transmit a master information block (MIB) comprising configuration information for a first cell of the access network;
• transmit a discovery reference signal, the discovery reference signal comprising at least one of a primary reference signal, a secondary reference signal, a cell-specific reference signal, or a combination thereof;
• receive a chirp signal from a user equipment (UE) as part of a random access procedure to establish a connection between the UE and the first cell, the chirp signal comprising at least one of a reference signal, a pilot signal, a UE identifier, a buffer status report, or a combination thereof, the chirp signal being configured as a system information request that specifies at least one system information block requested by the UE;
• select one or more of the at least one system information block requested by the UE;
• and
• transmit, in a unicast radio resource control (RRC) message, a system information response to the UE in response to the chirp signal, wherein the system information response comprises the one or more of the at least one system information block requested by the UE scrambled with a serving cell identifier.
