摘要:
The present invention relates to a broadband wireless access system, and more particularly to a method for efficiently communicating scheduling information about a broadcasting message to a terminal. The method for transmitting the broadcasting message in the broadband wireless access system comprises the steps of: transmitting a first map including scheduling information for at least one broadcasting message transmitted within a predetermined transmission unit to a terminal; and broadcasting the message through a resource region indicated by the scheduling information. In the method, it is desirable that the first map is an extended map of a second map including non-user specific control information.

An Apparatus and methods for communicating in a wireless access system using a medium access control protocol data unit (MAC PDU) is disclosed. The method comprises steps of receiving, by a mobile station (MS) from a base station (BS), a dynamic service addition request (AAI_DSA-REQ) message requesting to create a service flow, wherein the AAI_DSA-REQ message comprises a first MAC header type parameter indicating a type of a MAC header included in the MAC PDU of the service flow and a flow identifier (FID) identifying a connection associated with the service flow; transmitting, by the MS to the BS, a dynamic service addition response (AAI_DSA-RSP) message in response to the AAI_DSA-REQ message, wherein the AAI_DSA-RSP message comprises a second MAC header type parameter indicating the type of a MAC header included in the MAC PDU of the service flow; and communicating with the BS using the MAC PDU comprising the MAC header indicated by the second MAC header type parameter; wherein the MAC header type parameter indicates one of a generic MAC header (GMH) for general data packet transmission and a short-packet MAC header (SPMH) for small data packet transmission and a non-ARQ connection.

Various methods for efficiently transmitting data and various methods for allocating an ACK channel in a wireless access system are disclosed. In addition, various frame structures and MAC header structures for use in allocating an ACK channel are disclosed. A method for allocating an ACK channel includes receiving first data including ACK channel position information, transmitting an ACK signal on an ACK channel indicated by the ACK channel position information, and starting an ACK channel timer.

A frame structure used in a wireless access system and a method for allocating uplink control channels are provided. The method transmits a super-MAP including information regarding a control channel allocation method and control channel allocation information to a receiving end and receives a control signal through an uplink subframe indicated by the control channel allocation information using the control channel allocation method. Thus, the transmitting end can correctly allocate a control channel for each downlink burst.

A method for efficiently performing an initial access in an MS in a multi-carrier broadband wireless access system is disclosed. The method includes scanning a plurality of carriers supported by a BS, and selecting one of the scanned carriers as a first carrier and receiving an SFH of the first carrier. The SFH of the first carrier includes at least one of a field indicating load status of the first carrier and recommended network entry carrier information including information about a second carrier in good load status.

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.

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.

The present invention relates to a broadband wireless connection system, and more particularly, to a method for a base station to more efficiently allocate resources to a terminal, and to an apparatus for performing same. In a broadband wireless connection system according to one aspect of the present invention, a method for a base station for continuously allocating resources comprises the steps of: determining a size and location of a continuous allocation resource to be allocated through continuous resource allocation; comparing the size and location of the determined continuous allocation resource with those of previously allocated continuous allocation resources; and transmitting a map information element (A-MAP IE) including resource allocation information set according to the results of the comparison to a terminal.

A method of switching a radio resource mode allocated to a mobile station in a wireless access system is discussed. The method for switching the radio-resource mode allocated to a mobile station in the wireless access system includes, transmitting a first message comprising Carrier to Interference and Noise Ratio (CINR) information of a second radio-resource mode to a base station for requesting a switching from a first radio-resource mode allocated to the mobile station to the second radio-resource mode; and transmitting a predetermined codeword for indicating that the switching from the first radio-resource mode to the second radio-resource mode has not been normally performed, if a second message approving the switching of the radio-resource mode is not received within a predetermined time.
