Embodiment approach 1

[0051] [Structure of base station]

[0052] image 3 It is a block diagram showing the configuration of base station 100 according to Embodiment 1 of the present invention. exist image 3 Among them, the base station 100 includes: a control unit 101 , a scheduler 102 , a message generation unit 103 , an OFDM communication unit 104 , and a message processing unit 105 . Here, the control unit 101, the scheduler 102, the message generation unit 103, and the message processing unit 105 perform MAC layer processing, and the OFDM communication unit 104 performs physical layer processing.

[0053] The control unit 101 controls processing related to the MAC protocol.

[0054] The scheduler 102 allocates resources to a mobile station 200 as a communication partner or a group composed of a plurality of mobile stations 200 based on the control of the control unit 101 . The scheduler 102 outputs MS-ID, resource allocation information, and broadcast identification information (that is,...

Embodiment approach 2

[0074] In Embodiment 2, the unicast area is divided into a plurality of partial areas corresponding to the number of IEs. The configurations of the base station and mobile station according to Embodiment 2 are the same as those of base station 100 and mobile station 200 according to Embodiment 1.

[0075] The message generation unit 103 generates a control message to be transmitted on the downlink. Figure 6 It is a figure showing the structure of the control message of Embodiment 2.

[0076] exist Figure 6 , the control message 400 is divided into a multicast / broadcast area 410 and a unicast area 420 .

[0077] In addition, in Figure 6 Among them, the unicast area 420 is divided into two partial areas, that is, the first unicast area 420a and the second unicast area 420b.

[0078] In the first unicast area 420a, the frame transmitting the control message 400 includes a scheduling information element for the mobile station 200 which is the destination of one unicast IE. I...

Embodiment approach 3

[0085] In Embodiment 3, as in Embodiment 2, the unicast area is divided into a plurality of partial areas corresponding to the number of IEs. The configurations of the base station and mobile station according to Embodiment 3 are the same as those of base station 100 and mobile station 200 according to Embodiment 1.

[0086] The message generation unit 103 generates a control message to be transmitted on the downlink. Figure 7 It is a figure showing the structure of the control message of Embodiment 3.

[0087] exist Figure 7 , the control message 500 is divided into a multicast / broadcast area 510 and a unicast area 520 .

[0088] In addition, in Figure 7 Among them, the unicast area 520 is divided into three partial areas, that is, it is divided into a first unicast area 520a, a second unicast area 520b, and a third unicast area 520c.

[0089] In the first unicast area 520a, similarly to the first unicast area 420a described in Embodiment 2, a scheduling information el...

Abstract

Disclosed are transmission apparatus and a method for sending control information in which the processing time and power consumption at the reception side are reduced by improving the efficiency of reception processing at the reception side. At a base station (100), a information generating unit (103) generates control information and an OFDM communication unit (104) transmits a frame including the control information. The control information (300) has a unicast region (320) and broadcast / multicast regions (310), and scheduling information units (330) comprising a single MS-ID, a plurality of information elements (IE) that are transmitted to each mobile station (200) corresponding to this MS-ID, and an IE number indicator, which is the number information of this plurality of IEs, are included in a group of scheduling information units arranged in the unicast region (320).

Description

technical field [0001] The present invention relates to a sending device and a control message sending method for sending control messages for resource allocation in a multi-access wireless communication system. Background technique [0002] Currently, the wireless mobile communication system is developing towards the fourth generation (that is, 4G network). With the development to 4G, a significant increase in the number of users, user bandwidth, and mobility, which are system requirements, can be expected. [0003] In order to achieve the enhancements necessary for the system, some new technologies are being planned. As one of these technologies, there is Orthogonal Frequency Division Multiple Access (OFDMA) as a wireless technology proposed for WiMAX (IEEE802.16e) and 3GPP LTE (3rd Generation Partnership Project Long Term Evolution). [0004] The OFDM communication method is a technique of multiplexing and transmitting transmission data using a plurality of subcarriers....
