[0018]在 LTE (Long Term Evolution,长期演进)系统中,MAC(Media AccessControl,媒体接入控制)层具有逻辑信道复用功能,将多个逻辑信道的数据组织到一个MAC PDU (MACProtocol Data Unit, MAC协议数据单元)中,传给物理层进行发送。 [0018] In the LTE (Long Term Evolution, LTE) system, MAC (Media AccessControl, Media Access Control) layer having a logical channel multiplexing function, a plurality of logical channels of data organized into a MAC PDU (MACProtocol Data Unit , the MAC protocol data unit), the physical layer for transmission pass.

具体实施方式 detailed description

[0079] 本发明实施例基站将RN设备对应的多个RB对应的逻辑信道分成至少两个组,为每个组分配不同的逻辑信道组标识,为每个组对应的多个RB中的每个RB对应的逻辑信道分配LCID,其中同一组中每个RB对应的逻辑信道的LCID不同;将RB标识和逻辑信道标识的对应关系通知RN设备,其中逻辑信道标识包含逻辑信道号LCID和逻辑信道组标识。 [0079] Example embodiment of the present invention, a plurality of base station RB corresponding to the RN device corresponding to the logical channel into at least two groups, assigning different logical channel group identifier for each group, each corresponding to a plurality of RB groups per a logical channel corresponding to the RB allocation LCID, wherein different logical channels of the same group corresponding to each RB LCID; RN will inform the corresponding relationship between the device ID and logical channel identification RB, wherein the logical channel identifier comprises a logical channel and logical channel number LCID group identity. 由于将逻辑信道号进行分组复用,从而使与LTE系统相同长度的LCID能够标识大于LTE系统所标识的逻辑信道个数;进一步保证了系统架构变化后的性能。 Since the logical channel number for packet multiplexing, so that the LTE system LCID same length larger than the number capable of identifying the logical channel identified by the LTE system; further guarantee the performance of the system architecture changes.

[0080] 本发明实施例发送端根据RB标识和逻辑信道标识的对应关系,确定需要传输的RB的RB标识对应的逻辑信道标识,向接收端发送确定的逻辑信道标识,接收端根据对应的逻辑信道标识确定对应的逻辑信道。 [0080] The embodiments of the present invention based on the correspondence transmitting side RB ID and logical channel identification, needs to be transmitted to the RB RB logical channel identifier corresponding to the identifier, the determined logical channel identification transmitted to a receiving end, the receiving end according to the corresponding logical channel identification corresponding to the determined logical channel. 由于逻辑信道标识中的组标识和LCID对应一个RB标识,能够在业务调度时,使接收端能够确定扩展后的每个RB对应的逻辑信道,从而提高了RB扩展后传输的效率和成功率。 Since the group identifier and the logical channel identifier LCID identifier corresponds to one RB, when the service can be scheduled, the reception side can determine a logical channel corresponding to each RB the extended, thereby improving the efficiency and success rate of the RB extension transmission.

[0081] 在具体实施过程,中本发明实施例适用于LTE系统的LCID (即长度是5bit),也适用于其他LTE+系统(即LTE后续的系统)的LCID,本发明实施例能够使与LTE+系统相同长度的LCID能够标识大于LTE+系统所标识的逻辑信道个数。 [0081] In a specific embodiment the process of the present invention applied to the LTE system LCID embodiment (i.e., length 5bit), also applicable to other LTE + system (i.e. LTE subsequent system) LCID, embodiments of the present invention enables the LTE + LCID system capable of identifying the same length is greater than the number of logical systems identified LTE +.

[0082] 当然,本发明实施例并不局限于LTE和LTE+系统,其他有LCID的系统都适用本发明实施例,本发明实施例可以使与某一系统相同长度的LCID能够标识大于该系统所标识的逻辑信道个数。 [0082] Of course, embodiments of the present invention is not limited to LTE and LTE + system, the other system applies the LCID embodiment of the invention, embodiments of the present invention can make the LCID the same length of a system capable of identifying the system is greater than the number of logical channel identification.

[0083] 由于本发明实施例不同组的逻辑信道的LCID可以相同,只要每个组的逻辑信道的数量不大于可用LCID的数量,在对RB进行扩展后,只需要增加组的数量,就能够保证当前LCID的数量满足RB扩展后的需求。 [0083] Since the LCID different sets of logical channels according to embodiments of the present invention may be the same, as long as the number of logical channels of each group is no greater than the number of available LCID, after the RB is extended only to increase the number of groups, can be to ensure that the current number of LCID meet the needs of the RB expansion.

[0084] 下面结合说明书附图对本发明实施例作进一步详细描述。 [0084] The following description in conjunction with the accompanying drawings of the embodiments of the present invention is described in further detail.

[0085] 如图2所示,本发明实施例的基站包括:分配模块1、建立模块2和通知模块3。 [0085] As shown in FIG 2, an embodiment of the present invention, the base station comprising: an allocation module, a notification module establishing module 2 and 3.

[0086] 分配模块1,用于将RN设备对应的多个RB对应的逻辑信道分成至少两个组,为每个组分配不同的逻辑信道组标识,为每个组对应的多个RB中的每个RB对应的逻辑信道分配LCID,其中同一组中每个RB对应的逻辑信道的LCID不同。 [0086] 1 distribution module, a plurality of logical channel corresponding to the RB for the corresponding RN device into at least two groups, assigning different logical channel group identifier for each group, corresponding to the plurality of RB for each group each logical channel corresponding to the RB allocation LCID, wherein different logical channels of the same group LCID corresponding to each RB.

[0087] 其中,分配模块I可以先对多个RB进行分组,对RB分组并分配RB组标识和RB号的方式与对逻辑信道分组并分配逻辑信道组标识和LCID的方式相同。 [0087] wherein, prior to the allocation module I may be a plurality of RB groups, RB to RB group is allocated and a packet identification number and the RB group and the manner of logical identifier and the logical channel group assigned LCID same manner.

[0088] 每个RB对应一个逻辑信道,等同于对逻辑信道进行分组;然后可以为每个RB组分配RB组标识,为每个RB组对应的多个RB中的每个RB分配RB号,再对每个RB组标识分配对应的逻辑信道组标识。 [0088] Each RB corresponds to a logical channel, equivalent to a logical channel group; RB group ID may then be assigned for each RB group as a plurality of blocks of each RB group corresponding to RB number assigned to each RB, then assigned a logical channel group identifier corresponding to the group identifier for each RB. 其中任意两个RB组之间的RB组标识不同,组内两个RB之间的RB号不同,不同组的RB的RB号可以相同可以不同。 Wherein RB group identity between any two different RB groups, RB number different between the two groups RB, RB RB number of different groups may be the same or different.

[0089] 建立模块2,用于建立RB标识和逻辑信道标识的对应关系,其中逻辑信道标识包含LCID和逻辑信道组标识。 [0089] 2 establishment module configured to establish a corresponding relationship RB ID and logical channel identifier, wherein the logical channel identifier identifies the logical channel group and comprising LCID.

[0090] 具体的,逻辑信道标识包含该逻辑信道标识对应的RB标识的RB对应的逻辑信道的LCID和该逻辑信道所在的组对应的逻辑信道组标识;RB标识包含RB组标识和RB号。 [0090] Specifically, the logical channel identifier comprising a logical channel corresponding to the RB RB identifier corresponding to the identifier of the logical channel group and the LCID corresponding to the logical channel identifier where the logical channel group; RB identifier comprising identification and RB RB group number.

[0091] 通知模块3,用于将建立模块2建立的RB标识和逻辑信道标识的对应关系通知RN设备。 [0091] The notification module 3 for establishing the corresponding relationship between ID and RB established logical channel identification module 2 notifies the RN device.

[0092] 通知的RN设备是本发明实施例的基站服务的RN设备。 RN device [0092] RN is notified of the base station apparatus according to an embodiment of the present invention.

[0093] 其中,分配模块I具体将RB分成多少个组,以及每组中有多少个RB可以根据需要进行设定。 [0093] wherein RB assignment module into the I number of specific groups, and in each group the number of RB may be set as needed.

[0094] 分配模块I在分配标识时,任意两个组之间的逻辑信道组标识不同(RB组标识也不相同),组内两个逻辑信道之间的LCID不同,不同组的逻辑信道的LCID可以相同可以不同。 [0094] assigned when assigning identification module I, any logical channel group identity between two different groups (RB are not the same group identifier), two different logical channels between the LCID groups, different sets of logical channel LCID may be the same or different.

[0095] 较佳的,分配模块I可以根据RB等级或RB建立的时间将RN设备的多个RB对应的逻辑信道分成至少两个组。 [0095] Preferably, according to the time allocation module I or RB level established RB RB plurality of logical channels corresponding to the RN device into at least two groups.

[0096] 具体的,如果分配模块I根据RB等级分组,分配模块I可以将RB等级相近的RB对应的逻辑信道分为一组,比如有5个RB,需要分成两组,其中一组需要两个逻辑信道,另一组需要三个逻辑信道,5个RB的等级分别是1、2、3、4、5 ;分配模块I可以将等级I和2的RB对应的逻辑信道分成一组,等级3、4和5的RB对应的逻辑信道分成一组。 [0096] Specifically, if the dispensing module I The RB level packet distribution module I may be similar RB RB level corresponding to a logical channel into one group, such as a 5 RB, need divided into two groups, one group needs two logical channel, another group of logical channels need three, five levels of RB are 1,2,3,4,5; dispensing module I may be Class I and RB corresponding to logical channel 2 into a group level RB 3, 4 and 5 corresponding to the logical channel into a set.

[0097] 如果分配模块I根据RB建立的时间分组,分配模块I可以按照时间的先后顺序,从前到后或从后到前分组。 [0097] If the packet based on the time allocation module I established RB allocation module I may be in the order of time, from front to back or back to front packet. 比如有5个RB,需要分成两组,其中一组需要两个逻辑信道,另一组需要3个逻辑信道,5个RB的建立时间从前到后分别是RBl、RB2、RB3、RB4、RB5 ;如果按照从后到前分组,则分配模块I可以将RB4和RB5对应的逻辑信道分成一组,将RB1、RB2和RB3对应的逻辑信道分成一组。 For example there are five RB, need divided into two groups, one of which requires two logical channels, and the other required three logical channels, the RB setup time 5 from front to back are RBl, RB2, RB3, RB4, RB5; If the order from back to front packet, allocation module I may RB4 and RB5 into a corresponding logical channel group, RB1, RB2 and RB3 corresponding logical channel into a set. [0098] 进一步的,如果某RB释放,对应的LCID分配给新接入的RB对应的逻辑信道。 [0098] Further, if an RB release LCID corresponding to a logical channel corresponding to the RB allocated to the newly accessed. 这样虽然理论上RB个数很多,实现中可能同时存在的个数不一定很多,同时调度的业务可能只在一两个分组内,从而可以提高调度的效率。 Thus although in theory the number of RB number, the number may be realized not necessarily exist a lot of business may only be scheduled simultaneously in one or two packets, scheduling efficiency can be improved.

[0099] 其中,逻辑信道组标识可以是比特信息,也可以是RNTI (Cell RadioNetworkTemporary Identifier,小区无线网络临时标识)。 [0099] wherein the logical channel identifier may be a bit information group, and may be RNTI (Cell RadioNetworkTemporary Identifier, cell radio network temporary identity).

[0100] 如果逻辑信道组标识是比特信息,则比特信息的长度可以根据划分的组的数量确定,比如需要划分3个组,则可以采用2bit,比如00、01和10。 [0100] If the logical channel group identification information is the bit, the bit length information may be determined according to the number of the divided groups, such as the need to be divided three groups, 2bit may be employed, such as 00, 01 and 10. 如果需要划分10个组,则可以采用4bit。 If the groups need to be divided 10, can be employed 4bit.

[0101] 由于RNTI是RN设备在小区内的独有标识,用于对HXXH调度命令进行加扰,从而识别针对不同RN设备的调度,所以每个RN设备只有一个RNTI,如果逻辑信道组标识是RNTI,则分配模块I还需要为RN设备分配多个RNTI,其中分配的RNTI的数量不小于组的数量。 [0101] Since RNTI is an identifier unique to RN device within a cell, for HXXH scrambled scheduling command, scheduling to identify different RN devices, each device has only one RN RNTI, if the logical channel group ID is RNTI, the assignment module I also need to be allocated for the RN plurality RNTI apparatus, wherein the number of the RNTI allocated not less than the number of groups. 如果有多个RN设备,分配给每个RN设备的RNTI都应该不相同。 If there are a plurality of RN device, RNTI assigned to each RN device should not be the same.

[0102] 对于RN设备的RNTI也可以采用其他名称,比如C-RNT1、RN-RNTI,在实现上与RNTI相同,只是名称不同,在此不再赘述。 [0102] RNTI for the RN device may be employed other names, such as C-RNT1, RN-RNTI, in the realization of the same RNTI, but different names are not repeated here.

[0103] 其中,通知模块3可以通过高层信令(比如RRC(Radio Resource Control,无线资源控制)信令),将RB标识和逻辑信道标识的对应关系通知RN设备。 [0103] wherein the notification module 3 via high layer signaling (such as RRC (Radio Resource Control, RRC) signaling), the corresponding relationship between the logical channel identification RB ID and notifies the RN device.

[0104] 需要说明的是,本发明实施例并不局限于上述通知方式,其他能够将对应关系通知RN设备的方式都适用本发明实施例。 [0104] Incidentally, embodiments of the present invention is not limited to the notification methods, other possible to notify a correspondence relationship RN apparatus embodiment of the present invention are suitable embodiment.

[0105] 在具体实施过程中,本发明实施例基站的功能也可以由其他网络侧设备实现。 [0105] In a specific implementation, the base station functions of the embodiments of the present invention may also be implemented by other network devices.

[0106] 如图3所示,本发明实施例分配逻辑信道标识的方法包括下列步骤: Method [0106] As shown, the embodiment of the present invention allocate logical channel marker 3 comprises the following steps:

[0107] 步骤301、基站将RN设备对应的多个RB对应的逻辑信道分成至少两个组,为每个组分配不同的逻辑信道组标识,为每个组对应的多个RB中的每个RB对应的逻辑信道分配LCID,其中同一组中每个RB对应的逻辑信道的LCID不同。 [0107] Step 301, the base station apparatus corresponding to the RN corresponding to the plurality of logical RB into at least two groups, each group assigned to a different logical channel group identifier for each group corresponding to the plurality of RB each LCID logical channel corresponding to the RB assignment, wherein different logical channels of the same group LCID corresponding to each RB.

[0108] 其中,基站可以先对多个RB进行分组,每个RB对应一个逻辑信道,等同于对逻辑信道进行分组;然后可以为每个RB组分配RB组标识,为每个RB组对应的多个RB中的每个RB分配RB号,再对每个RB组标识分配对应的逻辑信道组标识。 [0108] wherein the first base station may be a plurality of RB groups, each corresponding to a logical RB, equal to logical channel group; RB group ID may then be assigned for each RB group, the RB group corresponding to each each of the plurality of RB RB allocation RB numbers, then logical channel group corresponding to the identifier assigned for each RB group identification.

[0109] 任意两个RB组之间的RB组标识不同,组内两个RB之间的RB号不同,不同组的RB的RB号可以相同可以不同。 [0109] RB group identity between any two different RB groups, RB number different between the two groups RB, RB RB number of different groups may be the same or different.

[0110] 步骤302、基站建立RB标识和逻辑信道标识的对应关系,其中逻辑信道标识包含LCID和逻辑信道组标识。 [0110] Step 302, the base station and the correspondence relationship between a logical channel identification RB ID, which identifies the logical channel and logical channel group comprising a LCID identifier.

[0111] 具体的,逻辑信道标识包含该逻辑信道标识对应的RB标识的RB对应的逻辑信道的LCID和该逻辑信道所在的组对应的逻辑信道组标识;RB标识包含RB组标识和RB号。 [0111] Specifically, the logical channel identifier comprising a logical channel corresponding to the RB RB identifier corresponding to the identifier of the logical channel group and the LCID corresponding to the logical channel identifier where the logical channel group; RB identifier comprising identification and RB RB group number.

[0112] 步骤303、基站将建立的RB标识和逻辑信道标识的对应关系通知RN设备。 [0112] Step 303, correspondence relationship between the logical channel identification RB ID and notifies the base station will establish RN device.

[0113] 通知的RN设备是基站服务的RN设备。 RN device [0113] RN is notified of the base station apparatus.

[0114] 步骤301中,基站具体将RB分成多少个组,以及每组中有多少个RB可以根据需要进行设定。 [0114] In step 301, the base station specifically RB is divided into the number of groups, each group and the number of RB may be set as needed.

[0115] 基站在分配标识时,任意两个组之间的逻辑信道组标识不同(RB组标识也不相同),组内两个逻辑信道之间的LCID不同,不同组的逻辑信道的LCID可以相同可以不同。 [0115] When the base station assigned identifier, identifying a logical channel group between any two different groups (RB group ID is not the same), between two different LCID logical groups within logical channels of different groups may LCID the same can be different.

[0116] 较佳的,基站可以根据RB等级或RB建立的时间将RN设备的多个RB分成至少两个组。 [0116] Preferably, the base station can be based on time or RB level established RB RB plurality of the RN device into at least two groups.

[0117] 具体的,如果分配模块I根据RB等级分组,基站可以将RB等级相近的RB对应的逻辑信道分为一组,比如有5个RB,需要分成两组,其中一组需要两个逻辑信道,另一组需要三个逻辑信道,5个RB的等级分别是1、2、3、4、5 ;分配模块I可以将等级I和2的RB对应的逻辑信道分成一组,等级3、4和5的RB对应的逻辑信道分成一组。 [0117] Specifically, if the dispensing module I The RB level packet, the base station may be similar RB RB level corresponding to a logical channel into one group, such as a 5 RB, need divided into two groups, one of which requires two logical channel, another group of logical channels require three, five levels of RB are 1,2,3,4,5; dispensing module I may be Class I and RB corresponding to logical channel 2 into a group, level 3, RB corresponding logical channels 4 and 5 into a group.

[0118] 如果分配模块I根据RB建立的时间分组,基站可以按照时间的先后顺序,从前到后或从后到前分组。 [0118] If the packet based on the time allocation module I established RB, the base station can follow the chronological order, from front to back or back to front packet. 比如有5个RB,需要分成两组,其中一组需要两个逻辑信道,另一组需要3个逻辑信道,5个RB的建立时间从前到后分别是RB1、RB2、RB3、RB4、RB5 ;如果按照从后到前分组,则分配模块I可以将RB4和RB5对应的逻辑信道分成一组,将RB1、RB2和RB3对应的逻辑信道分成一组。 For example there are five RB, need divided into two groups, one of which requires two logical channels, and the other required three logical channels, the RB setup time 5 from front to back are RB1, RB2, RB3, RB4, RB5; If the order from back to front packet, allocation module I may RB4 and RB5 into a corresponding logical channel group, RB1, RB2 and RB3 corresponding logical channel into a set.

[0119] 进一步的,如果某RB释放,对应的LCID分配给新接入的RB对应的逻辑信道。 [0119] Further, if an RB release LCID corresponding to a logical channel corresponding to the RB allocated to the newly accessed. 这样虽然理论上RB个数很多,实现中可能同时存在的个数不一定很多,同时调度的业务可能只在一两个分组内,从而可以提高调度的效率。 Thus although in theory the number of RB number, the number may be realized not necessarily exist a lot of business may only be scheduled simultaneously in one or two packets, scheduling efficiency can be improved.

[0120] 其中,逻辑信道组标识可以是比特信息,也可以是RNTI。 [0120] wherein the logical channel identifier may be a bit information group, it may be RNTI.

[0121] 如果逻辑信道组标识是比特信息,则比特信息的长度可以根据划分的组的数量确定,比如需要划分3个组,则可以采用2bit,比如00、01和10。 [0121] If the logical channel group identification information is the bit, the bit length information may be determined according to the number of the divided groups, such as the need to be divided three groups, 2bit may be employed, such as 00, 01 and 10. 如果需要划分10个组,则可以采用4bit。 If the groups need to be divided 10, can be employed 4bit.

[0122] 由于RNTI是RN设备在小区内的独有标识,用于对HXXH调度命令进行加扰,从而识别针对不同RN设备的调度,所以每个RN设备只有一个RNTI,如果逻辑信道组标识是RNTI,则分配模块I还需要为RN设备分配多个RNTI,其中分配的RNTI的数量不小于组的数量。 [0122] Since RNTI is an identifier unique to RN device within a cell, for HXXH scrambled scheduling command, scheduling to identify different RN devices, each device has only one RN RNTI, if the logical channel group ID is RNTI, the assignment module I also need to be allocated for the RN plurality RNTI apparatus, wherein the number of the RNTI allocated not less than the number of groups. 如果有多个RN设备,分配给每个RN设备的RNTI都应该不相同。 If there are a plurality of RN device, RNTI assigned to each RN device should not be the same.

[0123] 对于RN设备的RNTI也可以采用其他名称,比如C-RNT1、RN-RNTI,在实现上与RNTI相同,只是名称不同,在此不再赘述。 [0123] RNTI for the RN device may be employed other names, such as C-RNT1, RN-RNTI, in the realization of the same RNTI, but different names are not repeated here.

[0124] 步骤303中,基站可以通过高层信令(比如RRC信令),将RB标识和逻辑信道标识的对应关系通知RN设备。 In [0124] Step 303, the base station through higher layer signaling (for example RRC signaling), the corresponding relationship between the logical channel identification RB ID and notifies the RN device.

[0125] 需要说明的是,本发明实施例并不局限于上述通知方式,其他能够将对应关系通知RN设备的方式都适用本发明实施例。 [0125] Incidentally, embodiments of the present invention is not limited to the notification methods, other possible to notify a correspondence relationship RN apparatus embodiment of the present invention are suitable embodiment.

[0126] 如图4所示,本发明实施例确定逻辑信道的系统包括:发送设备10和接收设备20。 [0126] As shown in FIG 4, an embodiment of the present invention determines the logical channel system comprising: a transmitting apparatus 10 and receiving apparatus 20.

[0127] 发送设备10,用于根据RB标识和逻辑信道标识的对应关系,确定需要传输的RB的RB标识对应的逻辑信道标识,并发送确定的逻辑信道标识,其中逻辑信道标识包含逻辑信道组标识和LCID,任意两个逻辑信道组对应的逻辑信道组标识不同,同一逻辑信道组中每个RB对应的逻辑信道的LCID不同。 [0127] transmitting apparatus 10, according to a correspondence relationship between the logical channel identification ID and RB, the RB is determined to be transmitted to a logical channel identifier identifies the corresponding RB, and transmits the determined logical channel identifier, wherein the logical channel identifier comprising a logical channel group and the LCID identifier, a logical channel group corresponding to any two of the logical channel group to identify different, different logical channels in the same logical channel group corresponding to each RB LCID.

[0128] 其中,发送设备10中的RB标识和逻辑信道标识的对应关系可以采用图2的方式建立,也可以采用其他方式建立。 [0128] wherein the corresponding relationship between the logical channel identification RB ID and the transmission device 10 can be established using the embodiment of FIG. 2, may be established in other ways.

[0129] 接收设备20,用于接收来自发送设备10的逻辑信道标识,根据收到的逻辑信道标识确定对应的逻辑信道。 [0129] receiving device 20, for receiving a logical channel identity from the transmission device 10, determines the corresponding logical channel according to the received logical channel identification.

[0130] 如果发送设备10是基站,则接收设备20是RN设备,发送设备10可以包括本发明实施例图2的基站中的所有功能;如果发送设备10是RN设备,则接收设备20是基站,接收设备20可以包括本发明实施例图2的基站中的所有功能。 [0130] If the transmitting apparatus 10 is a base station, the receiving apparatus 20 is RN device, the transmitting device 10 may include all functions of a base station of FIG 2 in the embodiment of the present invention; if the transmitting device 10 is a RN device, the receiving device 20 is a base station , the receiving apparatus 20 may include a base station of FIG. 2 embodiment of the present invention all functions.

[0131] 其中,RB组标识对应的逻辑信道组标识可以是比特信息,也可以是RNTI,下面分别进行说明。 [0131] wherein, RB logical channel group corresponding to the group identifier may be a bit identifying information, may be RNTI, respectively, will be described below.

[0132] 方式一、逻辑信道组标识是RNTI。 [0132] one embodiment, the logical channel group ID is RNTI.

[0133] 1、发送设备10是基站,接收设备20是RN设备。 [0133] 1, 10 is a base station transmitting apparatus, receiving apparatus 20 is RN device.

[0134] 发送设备10在确定了逻辑信道标识后,采用逻辑信道标识中的RNTI加扰PDCCH(physical downlink control channel,物理下行控制信道)调度命令,向接收设备20发送采用确定的逻辑信道标识中的RNTI加扰的HXXH调度命令,以及向接收设备20发送包含确定的逻辑信道标识中的LCID的MACPDU。 [0134] After transmitting device 10 determines the logical channel identity, logical channel identity using the RNTI scrambled PDCCH (physical downlink control channel, PDCCH) scheduling command, the logical channel identity is determined using the apparatus 20 to the transmission and reception the RNTI scrambled HXXH scheduling command, and determine a logical channel identification comprising MACPDU LCID in transmitting to the receiving apparatus 20.

[0135] 相应的,接收设备20根据加扰HXXH调度命令的RNTI和收到的MACPDU中的LCID,确定逻辑信道标识,并确定逻辑信道标识对应的逻辑信道。 [0135] Accordingly, the receiving apparatus 20 according to a scrambling HXXH RNTI and the scheduling command received in the LCID MACPDU, determined logical channel identity, logical channel identity and determines the corresponding logical channel.

[0136] 比如发送设备10为接收设备20分配RNTIl和RNTI2,当发送设备10用RNTIl对PDCCH调度命令加扰,PDCCH调度的MAC PDU指示调度的是LCID = 01010的MAC SDU时,发送设备10与接收设备20之间传输的是RBl的数据;当发送设备10用RNTI2对HXXH调度命令加扰,PDCCH调度的MAC PDU指示调度的是LCID = 01010的MAC SDU时,发送设备10与接收设备20之间传输的则是RB2的数据。 [0136] For example, the transmission device 10 to the receiving device 20 assigned RNTIl and RNTI2, when the transmitting apparatus 10 by RNTIl scrambling the PDCCH scheduling command, PDCCH scheduling the MAC PDU indicating a scheduled is LCID = MAC SDU 01010, the transmission device 10 and the transmission between the receiving apparatus 20 is RBl data; when the transmitting apparatus 10 is scrambled HXXH RNTI2 scheduling command, scheduling of the PDCCH indicating a scheduled MAC PDU is LCID = MAC SDU 01010, the transmission apparatus and the reception apparatus 20 of 10 RB2 is transmitted between the data.

[0137] 2、发送设备10是RN设备,接收设备20是基站。 [0137] 2, RN device 10 is transmitting device, receiving device 20 is a base station.

[0138] 首先,接收设备20根据RB标识和逻辑信道标识的对应关系,确定需要接收的RB的RB标识对应的逻辑信道组标识,向发送设备10发送采用确定的RNTI加扰的HXXH调度命令。 [0138] First, the receiving apparatus 20 according to the correspondence RB ID and logical channel identification, to determine the logical channel identifier corresponding to the group identifier RB RB needs to receive and transmit scrambled HXXH RNTI using the determined scheduling command to the transmitting device 10.

[0139] 其次,发送设备10根据加扰roCCH调度命令的RNTI以及RB标识和逻辑信道标识的对应关系,确定逻辑信道标识,向接收设备20发送包含确定的逻辑信道标识中的LCID的MAC PDU。 [0139] Next, the scramble transmission apparatus 10 according to a scheduling command roCCH RNTI and the correspondence between RB ID and logical channel identification, to determine logical channel identity, logical channel identity comprises determining the transmission in the receiving apparatus 20 to the LCID MAC PDU.

[0140] 其中,发送设备10根据RNTI,从RB标识和逻辑信道标识的对应关系中找到逻辑信道标识(即RNTI)对应的RB组标识,然后从对应的RB组标识确定RB组,然后确定RB组中需要传输数据的RB的逻辑信道,找到该逻辑信道对应的LCID。 [0140] wherein, the transmitting device 10 RNTI, find logical channel identity (i.e. RNTI) corresponding to the group identifier from the correspondence relation RB RB ID and logical channel identification, and then determine the RB groups corresponding to the group identity RB, then RB is determined group needs to transmit data of a logical channel RB, the logical channel corresponding to find LCID.

[0141] 发送设备10将确定的LCID包含在MAC PDU中发送给接收设备20。 [0141] The determined transmission device 10 comprises LCID transmitted to the receiving apparatus 20 in the MAC PDU.

[0142] 最后,接收设备20根据加扰HXXH调度命令的RNTI和收到的MACPDU中的LCID,确定逻辑信道标识,并根据确定的逻辑信道标识确定对应的逻辑信道。 [0142] Finally, the receiving apparatus 20 according to a scrambling HXXH RNTI and the scheduling command received in the LCID MACPDU, logical channel identity is determined, and determines the corresponding logical channel according to the determined logical channel identification.

[0143] 方式二、逻辑信道组标识是比特信息。 [0143] Mode 2 is a logical channel group identification bit information.

[0144] 对于逻辑信道组标识是比特信息,发送设备10有多种发送方式。 [0144] For logical channel group identification information is the bit, the transmitting device 10 transmits a variety of ways.

[0145] 1、发送设备10将确定的逻辑信道标识中的逻辑信道组标识和LCID置于MAC PDU的MAC子头中,向接收设备20发送。 [0145] 1, the transmitting apparatus 10 identifies the logical channel group is determined logical channel identification in the MAC sub-header and LCID placed in the MAC PDU is transmitted to the receiving apparatus 20.

[0146] 由于MAC子头中有预留(R)比特,所以可以将预留比特作为逻辑信道组标识,具体可以参见图8、图9A和图9B。 [0146] Since the MAC sub-header has reserved (R) bits, bits may be reserved as a logical group identifier, specifically refer to FIG. 8, FIGS. 9A and Fig. 9B. 这样的好处是可以不扩展MAC子头的长度,但是由于预留比特长度有限,所以只能够表示4个逻辑信道组标识。 Such benefits can not extend the length of the MAC sub-header, but due to the limited length of the reserved bits, only four can be represented by a logical channel group ID.

[0147] 如果不采用预留比特,则需要扩展MAC子头的长度,以逻辑信道组标识长度是Ibyte为例,具体参见图1OA〜10C,图中G-1D表示逻辑信道组标识。 [0147] If the reserved bits is not used, the need to extend the length of the MAC sub-header to identify the logical channel group Ibyte length, for example, particular reference to FIG 1OA~10C, FIG. G-1D represents a logical channel group ID.

[0148] 需要说明的是,图中只是示例,G-1D的位置不是必须位于第二个字节,位于MAC子头的其他位置同样适用本发明实施例。 [0148] Note that, in FIG merely examples, G-1D are not necessarily located in the second position of the byte MAC sub-header located elsewhere in the embodiments of the invention are equally applicable.

[0149] 相应的,接收设备20根据MAC PDU的MAC子头中的逻辑信道组标识和LCID,确定逻辑信道标识,根据确定的逻辑信道标识,确定对应的逻辑信道。 [0149] Accordingly, the receiving apparatus 20 according to the logical channel group identifier MAC sub-header of the MAC PDU and the LCID, logical channel identity is determined according to the determined logical channel identification, to determine the corresponding logical channel.

[0150] 上面的方式都是每个逻辑信道组标识与一个LCID绑定在一起,如果需要调度一个组中的多个RB,则只需要发送一个逻辑信道组标识,相对于与每个LCID绑定一个逻辑信道组标识的方式可以节省资源。 [0150] The above embodiment is each logical channel group with a LCID identifier bound, if necessary scheduling a plurality of RB groups, needs to send only one logical channel group identifier with respect to each of the tied LCID given a logical way to group identity can save resources.

[0151] 具体的,发送设备10在需要调度一个组中的多个RB时,将确定的该组的逻辑信道组标识作为独立的MAC子头置于MAC PDU的MAC头中,将确定的该组中的多个RB对应的逻辑信道的LCID置于MAC PDU的MAC子头中,向接收设备20发送MAC TOU,其中一个LCID置于一个MAC子头中。 [0151] Specifically, the group identification of the logical channel group sending device 10 need to be scheduled when a plurality of RB groups, as determined independent of the MAC header MAC sub-header of the MAC PDU is placed, the determined a plurality of logical channel group corresponding to RB disposed LCID MAC subheader of MAC PDU, the MAC transmits the TOU 20 to the receiving apparatus, wherein a LCID placed in a MAC sub-header.

[0152] 由于需要调度一个组中的多个RB会确定多个逻辑信道标识,并且每个逻辑信道标识中的逻辑信道组标识都相同,所以可以将逻辑信道组标识作为一个独立的MAC子头,称为逻辑信道分组MAC子头,具体参见图11A。 [0152] Since the need to schedule a plurality of RB groups will determine a plurality of logical channel identity, logical channel group and each logical channel identifier identifies the same, the logical channel group may be identified as a separate MAC subheader , logical grouping called a MAC sub-header, see in particular FIG. 11A. 逻辑信道分组MAC子头位于特定位置,如所有对应MAC SDU子头最前面或最后面,具体可以参见图11B。 Logical MAC sub-header packets in specific locations, such as all of the corresponding MAC SDU subheader the front or back, specifically refer to FIG 11B.

[0153] 确定的每个逻辑信道标识中的LCID肯定不相同,所以可以把LCID置于图1lB的逻辑信道分组子头之后的MAC子头中,每个MAC子头中有一个LCID。 [0153] determined for each logical channel identifier LCID certainly not the same, the LCID can be disposed after the logical MAC sub-header packet of FIG 1lB subheader, each MAC sub-header has a LCID.

[0196] 步骤703、接收设备根据收到的逻辑信道标识确定对应的逻辑信道。 [0196] Step 703, the receiving device determines the corresponding logical channel according to the received logical channel identification.

[0197] 如果发送设备10是基站,则接收设备20是RN设备;如果发送设备10是RN设备,则接收设备20是基站。 [0197] If the transmitting device is a base station 10, the receiving apparatus 20 is RN device; if the transmitting device is a RN device 10, the receiving apparatus 20 is a base station.

[0198] 其中,RB组标识对应的逻辑信道组标识可以是比特信息,也可以是RNTI,下面分别进行说明。 [0198] wherein, RB logical channel group corresponding to the group identifier may be a bit identifying information, may be RNTI, respectively, will be described below.

[0199] 方式一、逻辑信道组标识是RNTI。 [0199] one embodiment, the logical channel group ID is RNTI.

[0200] 1、发送设备是基站,接收设备是RN设备。 [0200] 1, the transmission apparatus is a base station, the receiving device is a RN device.

[0201] 步骤701中,发送设备在确定了逻辑信道标识后,采用逻辑信道标识中的逻辑信道组标识RNTI加扰HXXH调度命令,向接收设备发送采用确定的逻辑信道标识中的RNTI加扰的HXXH调度命令,以及向接收设备发送包含确定的逻辑信道标识中的LCID的MACPDU。 In [0201] Step 701, after determining a sending device logical channel identity, logical channel identity using the identity of the logical channel group RNTI scrambled HXXH scheduling command, transmitted to a receiving device by using the determined logical channel identification in the scrambled RNTI HXXH scheduling command, and transmits to the receiving apparatus comprising MACPDU the determined logical channel identification in the LCID.

[0202] 相应的,步骤703中,接收设备根据加扰HXXH调度命令的RNTI和收到的MAC PDU中的LCID,确定逻辑信道标识,并确定逻辑信道标识对应的逻辑信道。 [0202] Accordingly, in step 703, the receiving apparatus according to the scheduling command HXXH RNTI, and MAC PDU received in the LCID, determined logical channel identity, logical channel identity and determines the corresponding logical channel.

[0203] 2、发送设备是RN设备,接收设备是基站。 [0203] 2, RN device is the transmitting device, the receiving device is a base station.

[0204] 步骤701之前还包括:接收设备根据RB标识和逻辑信道标识的对应关系,确定需要接收的RB的RB标识对应的逻辑信道标组识(即RNTI),向发送设备发送采用确定的RNTI加扰的I3DCCH调度命令。 [0204] Step 701 until further comprising: a receiving apparatus according to the correspondence RB ID and logical channel identification, the group identification mark determines that the logical channel identifier corresponding to the received RB RB (i.e. RNTI), transmits to the transmission apparatus determined using RNTI scrambled I3DCCH scheduling command.

[0205] 步骤701中,发送设备根据加扰HXXH调度命令的RNTI以及RB标识和逻辑信道标识的对应关系,确定逻辑信道标识。 In [0205] Step 701, the scramble transmission apparatus according to the scheduling command HXXH RNTI and the correspondence between the identifier and the logical channel identification RB, the logical channel identity is determined.

[0206] 步骤702中,发送设备向接收设备发送包含确定的逻辑信道标识中的LCID的MACPDU。 [0206] Step 702, the transmission device transmits a MACPDU LCID determined logical channel identifier to the receiving device.

[0207] 其中,发送设备10根据RNTI,从RB标识和逻辑信道标识的对应关系中找到逻辑信道标识(即RNTI)对应的RB组标识,然后从对应的RB组标识确定RB组,然后确定RB组中需要传输数据的RB的逻辑信道,找到该逻辑信道对应的LCID。 [0207] wherein, the transmitting device 10 RNTI, find logical channel identity (i.e. RNTI) corresponding to the group identifier from the correspondence relation RB RB ID and logical channel identification, and then determine the RB groups corresponding to the group identity RB, then RB is determined group needs to transmit data of a logical channel RB, the logical channel corresponding to find LCID.

[0208] 步骤702中,发送设备将LCID置于MAC PDU中发送给接收设备。 [0208] Step 702, the transmitting device transmits the MAC PDU is placed LCID to the receiving device.

[0209] 步骤703中,接收设备根据加扰HXXH调度命令的RNTI和收到的MACPDU中的LCID,确定逻辑信道标识,并根据确定的逻辑信道标识确定对应的逻辑信道。 [0209] In step 703, the receiving apparatus according to the scrambling HXXH RNTI and the scheduling command received in the LCID MACPDU, logical channel identity is determined, and determines the corresponding logical channel according to the determined logical channel identification.

[0210] 方式二、逻辑信道组标识是比特信息。 [0210] Mode 2 is a logical channel group identification bit information.

[0211] 对于逻辑信道组标识是比特信息,发送设备有多种发送方式。 [0211] For logical channel group identification information is the bit, the transmitting device transmits a variety of ways.

[0212] 1、步骤702中,发送设备将确定的逻辑信道标识中的逻辑信道组标识和LCID置于MAC PDU的MAC子头中,向接收设备发送。 [0212] 1, step 702, the logical channel identifier identifies the logical channel group transmitting device and the determined disposed LCID MAC sub-header of the MAC PDU is transmitted to the receiving apparatus.

[0213] 由于MAC子头中有预留(R)比特,所以可以将预留比特作为逻辑信道组标识,具体可以参见图8、图9A和图9B。 [0213] Since the MAC sub-header has reserved (R) bits, bits may be reserved as a logical group identifier, specifically refer to FIG. 8, FIGS. 9A and Fig. 9B. 这样的好处是可以不扩展MAC子头的长度,但是由于预留比特长度有限,所以只能够表示4个逻辑信道组标识。 Such benefits can not extend the length of the MAC sub-header, but due to the limited length of the reserved bits, only four can be represented by a logical channel group ID.

[0214] 如果不采用预留比特,则需要扩展MAC子头的长度,以逻辑信道组标识长度是Ibyte为例,具体参见图1OA〜10C,图中G-1D表示逻辑信道组标识。 [0214] If the reserved bits is not used, the need to extend the length of the MAC sub-header to identify the logical channel group Ibyte length, for example, particular reference to FIG 1OA~10C, FIG. G-1D represents a logical channel group ID.

[0215] 需要说明的是,图中只是示例,G-1D的位置不是必须位于第二个字节,位于MAC子头的其他位置同样适用本发明实施例。 [0215] Note that, in FIG merely examples, G-1D are not necessarily located in the second position of the byte MAC sub-header located elsewhere in the embodiments of the invention are equally applicable.

[0216] 相应的,步骤703中,接收设备根据MAC PDU的MAC子头中的逻辑信道组标识和LCID,确定逻辑信道标识,根据确定的逻辑信道标识,确定对应的逻辑信道。 [0216] Accordingly, in step 703, the receiving apparatus according to the logical channel group identifier MAC sub-header of the MAC PDU and the LCID, logical channel identity is determined according to the determined logical channel identification, to determine the corresponding logical channel.

[0217] 上面的方式都是每个逻辑信道组标识与一个LCID绑定在一起,如果需要调度一个组中的多个RB,则只需要发送一个逻辑信道组标识,相对于与每个LCID绑定一个逻辑信道组标识的方式可以节省资源。 [0217] The above embodiment is each logical channel group with a LCID identifier bound, if necessary scheduling a plurality of RB groups, needs to send only one logical channel group identifier with respect to each of the tied LCID given a logical way to group identity can save resources.

[0218] 具体的,步骤702中,发送设备在需要调度一个组中的多个RB时,将确定的该组的逻辑信道组标识作为独立的MAC子头置于MAC PDU的MAC头中,将确定的该组中的多个RB对应的逻辑信道的LCID置于MAC PDU的MAC子头中,向接收设备20发送MAC TOU,其中一个LCID置于一个MAC子头中。 [0218] Specifically, in step 702, logical channel group identifier of the group to be scheduled transmission apparatus when a plurality of RB groups, the determined MAC header as a separate MAC sub-header of the MAC PDU is placed in the determining the set of logical channels of the plurality of RB LCID corresponding MAC PDU is placed in a MAC subheader, the TOU MAC transmits to the receiving device 20, wherein a LCID placed in a MAC sub-header.

[0219] 由于需要调度一个组中的多个RB会确定多个逻辑信道标识,并且每个逻辑信道标识中的逻辑信道组标识都相同,所以可以将逻辑信道组标识作为一个独立的MAC子头,称为逻辑信道分组子头,具体参见图11A。 [0219] Since the need to schedule a plurality of RB groups will determine a plurality of logical channel identity, logical channel group and each logical channel identifier identifies the same, the logical channel group may be identified as a separate MAC subheader , logical grouping called a sub-header, see in particular FIG. 11A. 逻辑信道分组子头位于特定位置,如所有对应MACSDU子头最前面或最后面,具体可以参见图11B。 Logical sub-header packets in specific locations, such as all corresponding sub MACSDU front or back of the head, reference can be made to FIG 11B.

[0220] 确定的每个逻辑信道标识中的LCID肯定不相同,所以可以把LCID置于图1lB的逻辑信道分组子头之后的MAC子头中,每个MAC子头中有一个LCID。 [0220] determined for each logical channel identifier LCID certainly not the same, the LCID can be disposed after the logical MAC sub-header packet of FIG 1lB subheader, each MAC sub-header has a LCID.

[0221] 相应的,步骤703中,接收设备根据MAC PDU的MAC头中作为MAC子头的逻辑信道组标识和其他MAC子头中的LCID,确定多个逻辑信道标识,其中每个逻辑信道标识中的逻辑信道组标识相同;接收设备根据确定的多个逻辑信道标识,确定对应的逻辑信道。 [0221] Accordingly, in step 703, the receiving device a MAC header of the MAC PDU as a MAC sub-header identifies the logical channel group and the other MAC sub-header in the LCID, determining a plurality of logical channel identity, wherein each logical channel identifier the same logical channel group identifier; receiving apparatus according to the determined plurality of logical channel identification, to determine the corresponding logical channel.
