摘要:
A method and apparatus for transmitting and receiving system information in a wireless communication system are disclosed. A method for receiving system information by a mobile station (MS) of a wireless communication system includes receiving a secondary superframe header (S-SFH) change cycle from a base station (BS), and receiving a primary superframe header information element (P-SFH IE) including a first field indicating a change count of a plurality of secondary superframe header subpacket information elements (S-SFH SP IEs) from the base station (BS). Once each of the plurality of S-SFH SP IEs is changed, each of the plurality of S-SFH SP IEs remains unchanged during one or more S-SFH change cycles.

A method for transmitting control messages is disclosed. The method includes grouping a plurality of control messages for at least one user equipment based on at least one criteria of whether or not uplink ACK/NACK channel indexes are allowed to be implicitly used in the control messages, whether or not the user equipment corresponding to the control messages is able to implicitly use the uplink ACK/NACK channel indexes, sizes of Information Elements (IEs) of the control messages, whether or not the control messages are segmented into a predetermined number of subblocks, MCS levels applied to the control messages, sizes of allocated IEs of the control messages after applying the MCS levels, and frequency partitions in which the IEs of the control messages are present, and transmitting the grouped control messages. The control messages included in each of the groups generated by grouping are equal in at said least one criteria.

摘要:
A method for transmission of a downlink control message in a mobile communication system is provided. Said method comprises a step wherein user-specific control information (USCI) on a plurality of user equipment (UE) is arranged to generate a series of control message at a base station and a step wherein said control messages that have been generated are transmitted. The arrangement sequence value of a specific type of USCI within said control message is used as channel allocation information regarding the UE to which said specific USCI is transmitted.

摘要:
A method and device for performing a dedicated ranging for Machine To Machine (M2M) communication is provided. A M2M device receives a paging message indicating a dedicated ranging channel allocation from a base station. The dedicated ranging channel allocation is valid within a dedicated channel allocation timer.
摘要:
Provided are a method and a device for data transmission in a multiple carrier wave system. With respect to a carrier wave that includes a first guard band, a data band, and a second guard band on a frequency domain, at least one guard physical resource unit (guard PRU) is allocated to at least one of said first guard band and said second guard band, said guard PRU is mapped to a contiguous resource unit (CRU), and data are transmitted via the CRU to which said guard PRU is mapped. The CRU to which said guard PRU has been mapped is mapped to a contiguous logical resource unit (CLRU). The index of the CRU to which said guard PRU has been mapped and the index of the CRU to which the PRU of said data band has been mapped may be continuous.

摘要:
Provided are a method and device for ranging in a wireless communication system. A machine-to-machine (M2M) device receives an advanced air interface-system configuration descriptor (AAI-SCD) message including information on a dedicated ranging channel for the M2M device and an M2M parameter change count from a base station, and attempts ranging through the dedicated ranging channel to the base station. At this point, the M2M parameter change count orders information on the dedicated ranging channel in the AAI-SCD message to change.
