Abstract
Apparatuses, methods, and systems are disclosed for sending and/or receiving feedback for a system information request. One apparatus includes a transmitter that transmits information indicating a request for system information. The apparatus includes a processor that monitors, during a predetermined time period, for a feedback response indicating that the request for the system information was received.
Claims34
An apparatus comprising:
- a transmitter that transmits information indicating a request for system information, wherein the request for the system information comprises a request for system information that is only provided on-demand, the transmitted information comprises a physical random access channel preamble of a set of physical random access channel preambles that indicates the request for the on-demand system information, and each physical random access channel preamble of the set of physical random access channel preambles indicates specific system information;
- and
- a processor that monitors, during a predetermined time period, for a feedback response acknowledging reception of the request for the system information, wherein the feedback response is part of a random access response message and comprises only a medium access control subheader without a medium access control payload for a random access response, and the medium access control subheader comprises a physical random access channel preamble identifier corresponding to the physical random access channel preamble.
A method comprising:
- transmitting information indicating a request for system information, wherein the request for the system information comprises a request for system information that is only provided on-demand, the transmitted information comprises a physical random access channel preamble of a set of physical random access channel preambles that indicates the request for the on-demand system information, and each physical random access channel preamble of the set of physical random access channel preambles indicates specific system information;
- and
- monitoring, during a predetermined time period, for a feedback response acknowledging reception of the request for the system information, wherein the feedback response is part of a random access response message and comprises only a medium access control subheader without a medium access control payload for a random access response, and the medium access control subheader comprises a physical random access channel preamble identifier corresponding to the physical random access channel preamble.
An apparatus comprising:
- a receiver that receives information indicating a request for system information, wherein the request for the system information comprises a request for system information that is only provided on-demand, the received information comprises a physical random access channel preamble of a set of physical random access channel preambles that indicates the request for the on-demand system information, and each physical random access channel preamble of the set of physical random access channel preambles indicates specific system information;
- and
- a transmitter that transmits a feedback response acknowledging reception of the request for the system information, wherein the feedback response is part of a random access response message and comprises only a medium access control subheader without a medium access control payload for a random access response, and the medium access control subheader comprises a physical random access channel preamble identifier corresponding to the physical random access channel preamble.
A method comprising:
- receiving information indicating a request for system information, wherein the request for the system information comprises a request for system information that is only provided on-demand, the received information comprises a physical random access channel preamble of a set of physical random access channel preambles that indicates the request for the on-demand system information, and each physical random access channel preamble of the set of physical random access channel preambles indicates specific system information;
- and
- transmitting a feedback response acknowledging reception of the request for the system information, wherein the feedback response is part of a random access response message and comprises only a medium access control subheader without a medium access control payload for a random access response, and the medium access control subheader comprises a physical random access channel preamble identifier corresponding to the physical random access channel preamble.
