Embodiment Construction

[0050] The basic idea of ​​the present invention is: use the short time slot formed by the combination of UpPTS, DwPTS and 96chips GP to carry MICH, and only place MICH in the short time slot for carrying.

[0051] Further, since there are only 240 chips for transmitting data symbols in the short slot, therefore, in L NI When it is 8 symbols, the number of bits will be insufficient. At this time, 4 symbols can be used to carry the last L NI , the remaining seven L NI Each is still carried by 8 symbols; it is also possible to use the first seven L NI Each is carried by 8 symbols, and the remaining bits are not used to carry MICH. For the former case, 8 notification indications can be carried, and for the latter case, 7 notification indications can be carried.

[0052] The time slot structure of the short time slot adopted by the present invention is as follows: Figure 5 As shown, there are two parts including the premable of 112chips and the data symbols of 240chips, and t...

Abstract

The invention discloses a transmission method for MICH channel, combining uplink pilot frequency, downlink pilot frequency in single carrier frame, and middle protection interval to form short time slot, wherein the method also comprises: first sending channel estimation code on each code channel of each subframe during short time slot, then sequentially sending MBMS notification to indicate corresponding bits. Meanwhile, the invention also discloses a device for realizing MICH channel transmission, a method and a device for processing MICH channel carrying information; by using the invention, the MICH can be carried during short time slot, and the integrity of notification indicator can be ensured while supporting short time slot carried MICH.

Description

technical field [0001] The present invention relates to channel technology in Multimedia Broadcast / Multicast Service (MBMS), in particular to a transmission method, processing method and implementation device of MBMS Notification Indicator Channel (MICH). Background technique [0002] In order to effectively utilize the resources of the mobile communication network, the third generation mobile communication global standardization organization (3GPP) proposed the MBMS of the mobile communication network, thereby providing a point-to-multipoint service in which one data source sends data to multiple users in the mobile communication network , realize network resource sharing, and improve the utilization rate of network resources, especially air interface resources. The MBMS proposed by 3GPP can not only realize the multicast and broadcast of plain text and low-rate messages, but also realize the multicast and broadcast of high-speed multimedia services. [0003] MBMS technolo...
