Description
Technical field
Variable signaling is supported the present invention relates to the method and apparatus in wireless communication system, more particularly in cellular network system
ID (Identity, identifying) transmission method and device.
Background technology
Traditional third generation cooperative partner program (3GPP-3rd Generation Partner Project) Long Term Evolution
In (LTE-Long Term Evolution) system, MBSFN (Multimedia Broadcast Single are defined
Frequency Network, Multicast Broadcast Single Frequency Network) subframe (abbreviation M subframes).In traditional 3GPP versions, a system
Frame (System Frame) includes 10 subframes (Subframe), and numbering is { #0, #1, #2, #3, #4, #5, #6, #7, #8, #9 },
In these subframes, it is contemplated that ensure the transmission of the system messages such as broadcast message, with FDD (Frequency Division
Duplex, frequency division multiplexing) exemplified by pattern, only { #1, #2, #3, #6, #7, #8 } is configurable to M subframes.M subframes are mainly used in
MBMS (Multimedia Broadcast Multicast Service, the multi-medium multi-packet broadcasting multicast services) business of transmission.In M
In frame, broadcasting multicast service can not be multiplexed with other unicast services.
In Release 13, a kind of transmission means of new MBMS, SC-PTM (Single Cell Point to
Multipoint, single cell point is to multiple spot) transmission means be introduced into.SC-PTM compares traditional MBMS transmission means, most
Big difference is MBMS in PDSCH (Physcial Downling Shared Channel, the shared letter of physical down
Road) on, rather than transmitted on PMCH (Physical Multicast Channel, Physical Multicast Channel), and then MBMS is not
With being confined to transmit in M subframes.
In Plenary#72 meeting of 3GPP RAN, FeMTC (Further Enhanced Machine Type
Communication, the machine type communication further enhanced) and enhancing NB-IOT (Narrowband Internet of
Things, arrowband Internet of Things) the new WI of Release 14 (Work Item, work project verification) are listed in, one of them is important
Aspect is exactly under SC-PTM framework, and eMTC user and NB-IOT user need to support MBMS.
The content of the invention
In Release 13 SC-PTM systems, following two logic channels are introduced：
- SC-MCCH (Single Cell Multicast Control Channel, single cell multicast control channel)；
- SC-MTCH (Single Cell Multicast Transport Channel, single cell multicast transmission channel)；
The former is used for the control information for transmitting MBMS, and scrambles the mode and SC-RNTI of (Scrambling)
(Single Cell Radio Network Tempory Identity, single Cell Radio Network Temporary Identifier/Identity, Cell-RNTI) is relevant.The latter
For transmitting MBMS data message, and the mode scrambled and G-RNTI (Group Radio Network Tempory
Identity, organize Radio Network Temporary Identifier) it is relevant.SC-MCCH and SC-MTCH is transmitted in PDSCH, and by independent
PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) or EPDCCH (Enhanced
PDCCH, the Physical Downlink Control Channel of enhancing) indicate respectively the frequency domain resource that SC-MCCH and SC-MTCH takes.Work as SC-MCCH
Or during SC-MTCH generation errors of transmission, base station retransmits SC-MCCH or SC-MTCH to ensure the UE quality of reception.Traditional SC-
In PTM, SC-MCCH transmission is Cell-specific (cell is exclusive), and SC-MTCH is that (group is special by Group-specific
Category).In a cell (or a group), SC-MCCH (or SC-MTCH) is using the high-rise configuration of identical.
For MTC and NB-IOT, an important application scenarios are exactly that (Coverage Enhancement, cover CE
Lid enhancing).Under CE, the user for receiving MBMS in a cell simultaneously is likely to be under different coverage conditions, and different
The number of repetition (Repetion Number) of transmission required for UE is different.It is a kind of simple when needing to realize SC-PTM
Mode, exactly all SC-PTM transmission is required to use identical number of repetition, and then system will be had been based in cell
The most UE of (or in group) number of repetition carries out first transmission and re-transmission, thus, it is apparent that can have the waste of resource, and cause compared with
Low spectrum efficiency.And because the SC-MTCH and SC-MCCH time-domain positions transmitted are configured by high-level signaling, it is such a
Method dispatching flexibility is also poor.
In view of the above-mentioned problems, the invention provides solution.It should be noted that in the case where not conflicting, this Shen
The feature in embodiment and embodiment please can be arbitrarily mutually combined.For example, embodiment and embodiment in the UE of the application
In feature may apply in base station, vice versa.It should be further stated that although the original intention of the present invention is to be directed to
