Description

The transmission method and device of control information

Technical field

The present invention relates to the communications field, in particular to the transmission method and device of a kind of control information.

Background technology

1st, system information introduction

System information in Long Term Evolution (Long Term Evolution, referred to as LTE) system is divided into main system letter Cease block (Master Information Block, referred to as MIB) and several system information blocks (System Information Blocks, referred to as SIBs), from SIB1 to SIB20, MIB counterlogics channel is BCCH (Broadcast Control Channel, referred to as BCCH), transmission channel is broadcast channel (Broadcast Channel, referred to as BCH), Physical channel is Physical Broadcast Channel (Physical Broadcast Channel, referred to as PBCH).SIB counterlogics Channel is BCCH, and transmission channel is DSCH Downlink Shared Channel (Downlink Shared Channel, referred to as DL-SCH), Physical channel is Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH).With It is as shown in table 1 for the function of each non-primary system information down.

Table 1

In order to ensure uniformity that UE and network are understood broadcast system message, the general of system information modification cycle is introduced Read, the system information contents within the modification cycle can not change, and system information modification can only be from next system information Carve and start at the beginning of the modification cycle.I.e. after UE learns changing system information, in next start time in modification cycle Monitor new system information.LTE system supports the advice method of two kinds of system information changes：

Network side notifies Idle state and connected state UE changing system informations using beep-page message paging, and UE is next The modification cycle begins listening for new system information.The corresponding logic channel of the message is PCCH (Paging Control Channel), transmission channel is DL-SCH, and physical channel is PDSCH.

System Info ValueTag (system information change label) information is carried in SIB1, if the change that UE is read Label and the difference stored before, then it represents that change occurs for system information, it is necessary to re-read；UE storing system informations The term of validity be 3 hours, more than the time, then UE needs to re-read system information.

For the change of ETWS information (SIB10-11) and CMAS information (SIB12) in system information, it is allowed to UE does not use read access time point specified in system information changing process.There is the UE for receiving ETWS or CMAS abilities ETWS or CMAS Notification of Changes information has been detected whether by beep-page message, has found to read immediately during Notification of Changes ETWS and the particular content in CMAS system information blocks.

The UE of connected state and Idle state is only read out and updated to the system information that it needs, and unwanted for its System information can be without reading and related renewal.

2nd, MBMS is introduced

Multicast service (Multimedia Broadcast and Multicast in LTE (Long Term Evolution) Service, referred to as MBMS) eMBMS that is otherwise known as (evolved MBMS), major function is in LTE system It is middle to realize broadcast and multicast service.Current MBMS is mainly realized by mixed cell, that is, transmits the small of MBMS Also transmit unicast service simultaneously in area.And multiple MBMS cells can constitute a multicast single frequency network (Multimedia Broadcast multicast service Single Frequency Network, referred to as MBSFN) area Domain.The transmission of current MBMS and the transmission of unicast service are blended in what same carrier wave was transmitted.

EMBMS related control informations include：

(1) system information：System level control information related MBMS, mainly including SIB13/15/16.

(2) logical control channel MCCH (Multicast Control Channel)：

Multicast control channel, is the down channel of one point-to-multipoint (point-to-multipoint), for network to UE Transmit the related control information of MBMS and the counting information for counting MBMS interest, one MCCH can correspond to one or more MTCH；The channel only has the UE that can receive MBMS just to make With.Base station can be by MCCH modification cycle and repetition period by system broadcasts notice UE, and the modification cycle is usually weight X times of multiple cycle, within a modification cycle, the MCCH information that all repetition periods send is the same, and this is In order to ensure MCCH reliable reception.The change of information is even more in PDCCH (Physical Downlink in MCCH simultaneously Control Channel) in pass through M-RNTI (Multicast-Radio Network Temporary Identity) scrambling Bit instruction.UE is after MCCH Notification of Changes is got, it is necessary to re-read the MCCH.The logic is believed The corresponding transmission channel in road is MCH (Multicast Channel, Multicast Channel), and physical channel is Physical Multicast Channel (Physical Multicast Channel, referred to as PMCH).

(3) eMBMS MAC scheduling controllings, MSI (MCHScheduling Information) MAC CE (Control Element):

MSI is the control signaling as MAC layer, at first of each MSP (MCH Scheduling Period) Transmitted in subframe, for indicate each MTCH position and current MCH in the subframe that is not used.

(4) logical data channel (Multicast Traffic Channel, referred to as MTCH)：

Logical Traffic Channels, are a point-to-multipoint down channels, and MBMS number is transmitted to UE for network According to；The channel only has the UE that can receive MBMS just to use.MTCH configuration information is by its correspondence MCCH indicate.Network indicates MTCH using MCCH to UE, so that reaching makes UE receive in MTCH The purpose of the MBMS of upper carrying.The corresponding transmission channel of the logic channel is Multicast Channel (Multicast Channel, referred to as MCH), physical channel is that (Physical Multicast Channel are referred to as Physical Multicast Channel PMCH)。

(5) transmission channel (Multicast Channel, referred to as MCH) and physical channel (Physical Multicast Channel, referred to as PMCH)：

MCCH and MTCH are both mapped on MCH and are transmitted, and MCH is re-mapped and passed on PMCH It is defeated.Each MCH is transmitted in MCH dispatching cycles, MCH (MCH Scheduling dispatching cycle Period, referred to as i.e. MSP).

2nd, SC-PTM technology introductions

When MBMS is sent in single subdistrict, in order to improve the efficiency of the utilization of resources, by MBMS industry Be engaged in Physical Downlink Shared Channel (the Physical Downlink Shared communicated by way of dynamic dispatching in unicast Channel, referred to as PDSCH) middle transmission.SC-PTM transmission still needs corresponding control channel (such as SC-MCCH, Single Cell MCCH) and data channel (such as SC-MTCH, Single Cell MTCH).And control Channel and data channel are transmitted by different physical channels respectively.Its system information mainly includes SIB20.

The corresponding transmission channels of SC-MCCH and SC-MTCH are DL-SCH, and physical channel is PDSCH.Current MBMS is to be blended in same carrier wave with unicast service to send, when using independent MBMS carrier waves transmission MBMS During business, the independent MBMS carrier waves no longer need to send the related control information of unicast, and current LTE system lacks Independent MBMS carrier waves only send the mechanism of MBMS control information.
