Embodiment 1

[0168] Embodiment 1: Channel correspondence of control information (only PMCH);

[0169] Figure 5 is a schematic diagram of the corresponding relationship between the transmission channels of the control information according to the preferred embodiment of the present invention Figure 1 ,Such as Figure 5 As shown, the corresponding relationship between the transmission channels of the control information is:

[0170] MCCH: corresponding to MCH, corresponding to PMCH. The position of the subframe to be sent is specified by the BCCH information, including the sending period and the repetition period.

[0171] PCCH: corresponding to PCH, corresponding to PMCH. The subframe position to be sent is specified by the scheduling MAC CE.

[0172] BCCH: corresponding to BCH, corresponding to PMCH. The sending position is the time-frequency position stipulated in the protocol. For example, the transmission period of MIB information is fixed at 40ms, and the same content is retran...

Embodiment 2

[0176] Embodiment 2: Channel correspondence of control information (including PBCH, PMCH, PDSCH)

[0177] Image 6 is a schematic diagram of the corresponding relationship between the transmission channels of the control information according to the preferred embodiment of the present invention Figure II ,Such as Image 6 As shown, the corresponding relationship between the transmission channels of the control information is:

[0178] MCCH: corresponding to MCH, corresponding to PMCH. The position of the subframe to be sent is specified by the BCCH information, including the sending period and the repetition period.

[0179] PCCH: corresponding to PCH, corresponding to PDSCH. The subframe position to be sent is specified by the scheduling MAC CE.

[0180] BCCH: corresponding to BCH, corresponding to PBCH. The sending position is the time-frequency position stipulated in the protocol. For example, the transmission period of MIB information is fixed at 40ms, and the same ...

Embodiment 3

[0184] Embodiment 3: paging notifies the updating of control information.

[0185] There may be multiple MCCH channels (for example, 5) on the network side, and each channel corresponds to a different MBSFN area.

[0186] Step 1) The network side sends a paging message, in which 5 bits correspond to different MCCH update notifications, and when 1 bit is 1, it is notified that the MCCH information has changed.

[0187] Step 2) From step 1, after the UE receives the change notification of the MCCH, the UE reads the information in the MCCH again.

Abstract

The invention provides a control information transmission method and device. The method comprises the step that control information sent by an independent MBMS carrier is sent through different logic channels, wherein the logic channels comprise at least one of the following channels: a master logic control channel, an auxiliary logic control channel, and an MBMS logic control channel. Through adoption of the control information transmission method and device, a mechanical problem that the current communication system lacks the independent MBMS carrier and sends only the MBMS control information is solved, sending of the MBMS control information is improved, and the MBMS service is received correctly.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a control information transmission method and device. Background technique [0002] 1. System Information Introduction [0003] System information in a Long Term Evolution (LTE) system is divided into a master system information block (Master Information Block, referred to as MIB) and several system information blocks (System Information Blocks, referred to as SIBs), from SIB1 to The logical channel corresponding to SIB20 and MIB is Broadcast Control Channel (BCCH for short), the transmission channel is Broadcast Channel (BCH for short), and the physical channel is Physical Broadcast Channel (PBCH for short). The logical channel corresponding to the SIB is BCCH, the transport channel is a downlink shared channel (Downlink Shared Channel, DL-SCH for short), and the physical channel is a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH for short). The f...
