摘要:
The present invention provides a method of a Base Station (BS) updating system information using a superframe structure in a wireless communication system, comprising transmitting a primary header including system scheduling information pertinent to an update of the system information and transmitting an updated secondary header. The system scheduling information comprises secondary header change state information indicating a change state of the updated secondary header, secondary header applying information indicating whether the secondary header change state information is applied to a current system, and a secondary header change indicator indicating the updated secondary header.

Disclosed is a method of a handover in a wireless communication system. The method includes transmitting a handover request message to the service BS, and receiving a handover command message from the service BS in response to the handover request message. Multi-carriers are assigned to a terminal in advance right before a handover, and all or some of the multi-carriers are activated right after the handover. Therefore, multi-carrier are effectively utilized.

There is provided a method for handover of a terminal in a wireless access system using multi-carrier operation. The method comprises: receiving a handover command message from a serving base station; and performing network reentry to a target base station based on the handover command message, wherein the handover command message includes information required for handover to the target base station and information on whether the target base station supports handover using multi-carriers. Accordingly, it is possible to efficiently perform the handover in the wireless access system supporting the multi-carriers.
摘要:
A method of transmitting broadcast information by using multiple carriers is provided. The method includes: configuring a superframe for an operation of the multiple carriers; and transmitting the broadcast information through at least one primary carrier selected from the multiple carriers. Accordingly, the multiple carrier system can effectively manage respective carriers, and particularly can effectively use radio resources in transmission of broadcast information.

A method of acknowledgment by a receiver includes: receiving a control message via a payload of a medium access control protocol data unit (MAC PDU) from a transmitter or receiving control information through an extended header or signaling header of the MAC PDU; and transmitting an acknowledgment of the control message or control information through an acknowledgment extended header containing information about whether the acknowledgment is an acknowledgment of the control message or an acknowledgment of the control information.

When MBS information is updated, a base station transmits a first message to a terminal. The first message includes a service flow update indicator for indicating a scheme for describing a current MBS identifier (ID) and flow ID to be updated, information on the current MBS ID and flow ID described by the scheme indicated by the service flow update indicator, and new MBS information. The terminal transmits a second message to the base station in response to the first message.
摘要:
Method receiving Multicast Broadcast Service (MBS) in a wireless communication system is provided. The method comprises receiving a Dynamic Service Addition (DSA) message through a primary carrier, from a Base Station (BS); switching from the primary carrier to a secondary carrier based on the DSA message; receiving an MBS Configuration message through the secondary carrier, from the BS; and receiving MBS data through the secondary carrier based on the MBS Configuration message, from the BS.

Provided is a method for obtaining superframe header (SFH) information in a neighboring base station advertisement (NBR-ADV) message at a terminal. In the method, a NBR-ADV message having SFH information set per each carrier is received from a serving base station. The SFH information of each carrier is obtained from the NBR-ADV message. In the obtaining the SFH information of each carrier, SFH information of a corresponding carrier is obtained based on SFH information of a previous carrier when a predetermined field is set as a predetermined value.

When zone allocation information of sub-bands is changed, a terminal receives a new MBS configuration message after a lifetime of an MBS configuration message at a time when the changed zone allocation information is received is expired. The terminal applies the changed zone allocation information at the beginning of the first MSI of the new MBS configuration message.
