[0047] Figure 2A is a view illustrating an efficient format of a multi-user group according to the first embodiment of the present invention. will now refer to Figure 2A The efficient format of the multi-user group according to the first embodiment of the present invention will be described in detail.

[0048] Figure 2A The multi-user group shown in is roughly divided into three parts, including:

[0049] (1) Media Access Control (MAC) header 210;

[0050] (2) MAC Payload 220; and

[0051] (3) MAC trailer 230.

[0052] The MAC header 210, that is, the part including information on addresses, lengths, and formats of several user packets contained in the MAC packet, includes a minimum of one PacketInfo field or a maximum of 8 PacketInfo fields. Although the number of PacketInfo fields is scalable, the preferred maximum number of PacketInfo fields is 8 when considering the size of packets provided in the 1xEVDO system. Thus, the minimum and maximum numbers of PacketInfo...

[0068] Figure 6A is a view illustrating an exemplary high-efficiency format of a multi-user group according to the second embodiment of the present invention. will now refer to Figure 6A The efficient format of the multi-user group according to the second embodiment of the present invention will be described in detail.

[0069] Basically as described above, Figure 6A The multi-user group shown in can be roughly divided into three parts, including:

[0070] (1) MAC header 610;

[0071] (2) MAC Payload 620; and

[0072] (3) MAC trailer 630.

[0073] The MAC header 610, that is, the part including information about the address, length, and format of several user packets contained in the MAC packet, includes at least one Length field or at most 8 Length fields, and includes at least one PacketInfo field or at most 8 PacketInfo field. Similarly, the number of PacketInfo fields is expandable. However, the preferred maximum number of PacketInfo fields is 8 when considering...

[0087] Figure 9A is a view illustrating an exemplary high-efficiency format of a multi-user group according to the third embodiment of the present invention. will now refer to Figure 9A The efficient format of the multi-user group according to the third embodiment of the present invention will be described in detail.

[0088] Basically as described above, Figure 9A The multi-user group shown in can be roughly divided into three parts, including:

[0089] (1) MAC header 910;

[0090] (2) MAC Payload 920; and

[0091] (3) MAC trailer 930.

[0092] Each of n MAC headers 910 is a part including information on addresses, lengths, and formats of several user packets contained in the MAC packet. Each of the n MAC headers 910 may include a minimum of one Length field or a maximum of 8 Length fields, and a minimum of one PacketInfo field or a maximum of 8 PacketInfo fields. Similarly, the possible number of PacketInfo fields contained in a MAC packet is expandable. However, ...

Abstract

An apparatus and method is provided for generating one packet with transmission data and transmitting the packet from an access network transceiver system (ANTS) to a plurality of access terminals (ATs) in a mobile communication system including the ATs and the ANTS which are capable of performing packet data communication with ATs located in coverage thereof. The method includes the steps of generating a medium access control (MAC) header including information on a receiving AT's address, a length and format for transmission data, generating a MAC payload by consecutively connecting data units to be transmitted to the receiving AT, and generating a MAC trailer. The ANTS pads '0' bits to the MAC header if a predetermined MAC size is greater than a sum of lengths of the MAC header, the MACpayload and the MAC trailer.

Description

technical field [0001] The present invention generally relates to apparatuses and methods for transmitting / receiving data in a mobile communication system. In particular, the present invention relates to an apparatus and method for transmitting / receiving packet data in a mobile communication system. Background technique [0002] Mobile communication systems have been developed for providing voice services ensuring mobility of users. With rapid progress in communication technology, mobile communication systems have developed into systems that can also provide data services. Recently, research has focused on high-speed data transmission in Code Division Multiple Access (CDMA) mobile communication systems. A 1x Evolution Data Optimized (1xEVDO) system is a typical mobile communication system having a channel structure for the high-speed data transmission. The 1xEVDO system is proposed in the 3rd Generation Partnership Project 2 (3GPP2), which is used to complement the data c...
