System information broadcast in machine-to-machine radio access systems
First Claim
1. A wireless communication method comprising:
- detecting a content associated with each of a plurality of system information blocks (SIBs) from the plurality of SIBs using a downlink channel in a wireless communication network;
storing the content associated with each of the plurality of SIBs;
detecting, from the downlink channel in the wireless communication network, bits corresponding to a first information associated with a coverage, the coverage corresponding to a Signal-to-Noise-plus-Interference-Ratio (SINR) below a cell edge SINR;
detecting a second information indicating that the contents associated with each of the plurality of SIBs from the downlink channel are changed when a User Equipment (UE) is determined to have a coverage corresponding to a Signal-to-Noise-plus-Interference-Ratio (SINR) below a cell edge SINR based on the detected bits; and
when the second information indicates that at least one of the contents stored in the SIBs is changed, invalidating the content in the SIBs whose change was indicated.

Abstract
A method may include detecting multiple system-information block (SIB) blocks and associated content. The associated content may be stored. The method may further include detecting multiple change flags associated with the multiple SIB blocks, each of the multiple change flags associated with one of the multiple SIB blocks. In response to detecting a change flag having a first change flag value, content of the SIB block associated with the first change flag may be reused. The first change flag value may represent an absence of a change to the content of the SIB block associated with the first change flag. In response to detecting the change flag having a second change flag value, the SIB block associated with the second change flag may be detected and the associated content stored. The second change flag value may represent a change to the content of the associated SIB blocks.

5. A terminal comprising:
-
a memory that stores a plurality of instructions; and a processor coupled to the memory and configured to execute the plurality of instructions to; detect a content associated with each of a plurality of system information blocks (SIBs) from the plurality of SIBs using a downlink channel in a wireless communication network; store the content associated with each of the plurality of SIBs; detect, from the downlink channel in the wireless communication network, bits corresponding to a first information associated with a coverage, the coverage corresponding to a Signal-to-Noise-plus-Interference-Ratio (SINR) below a cell edge SINR; detect a second information indicating that the contents associated with each of the plurality of SIBs from the downlink channels are changed when the terminal is determined to have a coverage corresponding to a Signal-to-Noise-plus-Interference-Ratio (SINR) below a cell edge SINR based on the detected bits; and when the second information indicates that at least one of the contents stored in the SIBs is changed, invalidating the content in the SIBs whose change was indicated. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. A base station comprising:
-
a memory that stores a plurality of instructions; and a processor coupled to the memory and configured to execute the plurality of instructions to; transmit, in a downlink channel in a wireless communication network, bits corresponding to a first information associated with coverage, the coverage corresponding to a Signal-to-Noise-plus-Interference-Ratio (SINR) below a cell edge SINR; transmit a content associated with each of a plurality of system information blocks (SIBs) in the downlink channel; and transmit a second information indicating whether the contents associated with each of the plurality of SIBs in the downlink channel are changed when a User Equipment (UE) is determined to have a coverage corresponding to a Signal-to-Noise-plus-Interference-Ratio (SINR) below a cell edge SINR based on the bits corresponding to the first information associated with the coverage corresponding to a Signal-to-Noise-plus-Interference-Ratio (SINR) below a cell edge SINR. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
