[0085] 步骤101 :演进基站(eNB,Evolution Node Base)根据LTE-A系统中各个载波的频点,按照预设编号分配规则,为每个频点的载波分配一个唯一的编号,将该分配规则广播给系统中的所有用户设备(UE,User Equipment)。 [0085] Step 101: evolved NodeB (eNB, Evolution Node Base) in the LTE-A system according to frequency of each carrier, according to a preset number allocation rule, a unique number assigned to each carrier frequency of the allocated All user equipment (UE, user equipment) rules broadcast to the system. [0086] 预设编号分配规则可以是预先配置在eNB上的,也可以是eNB和所有UE预先约定好的。 [0086] allocation rule preset number may be preconfigured on the eNB, and eNB may be pre-agreed for all UE.

[0087] 载波的编号可采用N(N为非负整数)比特二进制数字表示。 [0087] The number of carriers can be N (N is a nonnegative integer) bit binary digital representation.

[0088] “ =「log21,其中,「1为向上取整运算符,M为LTE-A系统中所有载波的频点数。 [0088] "=" log21, wherein "ceil 1 operator, M being LTE-A system, the number of frequencies for all carriers.

[0089] 编号分配规则可以如下: [0089] Item assignment rules may be as follows:

[0091] 规则二、按照eNB确定要在步骤102中广播给UE的各个频点的顺序,依次将各个 [0091] The second rule, in accordance with the order of the respective frequency eNB determines to be broadcast in step 102 to the UE, each sequentially

频点的载波编号为0、1、2、3.......,例如:若有频点a、b、C、d,eNB确定在步骤102中将各 Carrier frequency point numbered 0,1,2,3 ......., for example: if the frequency point a, b, C, d, eNB 102 determines at each step in the

频点广播给UE的顺序为b、c、a、d,则频点b、c、a、d的载波的编号分别为0、1、2、3。 Order frequency broadcast to the UE is b, c, a, d, the frequency b, c, a, d carriers numbered 0,1,2,3.

[0092] 步骤102 :eNB向系统中的所有UE广播系统中所有载波的频点。 [0092] Step 102: eNB UE broadcasting system to all systems in all frequency carriers.

[0094] 若采用编号分配规则一,则eNB可不考虑频点的广播顺序;若采用编号分配规则二,eNB需要在确定各频点的广播顺序后,记录各载波的频点与编号的对应关系,以作为后续下发下行控制信令的依据。 [0094] The use of a number assignment rule one, the eNB may consider a broadcast order frequency point; the use of a number assignment rule two, eNB needs after determining the broadcast order of the frequency is recorded the correspondence relationship of each carrier frequency and the number of , issued as the subsequent downlink control signaling basis.

[0095] 步骤103 =UE接收并记录eNB发来的系统中所有载波的频点。 [0095] Step 103 = UE receives and records sent by the eNB in ​​the system frequency for all carriers.

[0096] 步骤104 :eNB要在载波B上向UEl传送针对载波A的下行控制信令,在该下行控制信令中放入载波A的编号,将该下行控制信令承载在载波B上发送给UEl。 [0096] Step 104: eNB to the downlink control signaling for carrier A is placed on carrier B to UEl transmits the downlink control signaling number of carrier A, the bearer downlink control signaling transmitted on carrier B to UEl.

[0097] 步骤105 :UE1接收该下行控制信令,从信令中读取载波A的编号,根据编号分配规则以及步骤103中记录的系统中所有载波的频点,确定载波A的频点,在该频点对应的载波A上执行该下行控制信令中的内容。 [0097] Step 105: UE1 receives the downlink control signaling, a carrier number A read from the signaling in accordance with the allocation rule of frequency point number system and recorded in step 103 for all the carriers, determining the frequency of the carrier A, the execution contents of the downlink control signaling on the carrier frequency corresponding to the point a.

[0098] 在实际应用中,若编号分配规则是预先由管理人员配置在eNB上的,则步骤101 中,eNB也可不将该分配规则广播给系统中的所有UE,而是在步骤102中将该分配规则连同系统中的所有载波的频点一起广播给所有UE,或者,直接在步骤102中将各载波的频点和编号的对应关系广播给所有UE。 [0098] In practice, if the numbers are assigned in advance by management rule disposed on the eNB, then in step 101, the eNB may not be broadcast to all UE allocation rules in the system, but rather in step 102 will the frequency allocation rule, along with all carriers in the system along with a broadcast to all the UE, or, in the correspondence in step 102 of each broadcast carrier frequency and the number of all directly to UE.

[0099] 若eNB在步骤102中将各载波的频点和编号的对应关系广播给所有UE,则UE需要记录各载波的频点和编号的对应关系,且,在步骤105中,UE 1可直接根据该对应关系找到载波A的频点。 [0099] When the eNB in ​​step 102 the correspondence relationship of each broadcast carrier frequency and the number to all the UE, the UE needs to record the relationship between each frequency and the number of carriers, and, in step 105, UE 1 can a directly to the carrier frequency based on the correspondence relationship.

[0100] 图2为本发明实施例二提供的跨载波下行控制信道指示方法流程图,如图2所示, 其具体步骤如下: [0100] FIG 2 cross-carrier downlink control channel indicates a flowchart of a method according to a second embodiment of the present invention, shown in Figure 2, the specific steps are as follows:

[0101] 步骤201 :对于LTE-A系统中每个采用聚合载波的UE, eNB根据该UE的聚合载波集中各载波的频点,按照预设的该UE的载波编号分配规则,为该UE的聚合载波集中的每个频点的载波分配一个唯一的编号,将该UE的载波编号分配规则发送给该UE。 [0101] Step 201: LTE-A system for each UE using polymeric carriers, the eNB according to the aggregation of the carrier set each carrier frequency of the UE, according to a preset rule carrier number allocated to the UE, the UE's each polymeric carrier frequency in the set of carriers assigned a unique number, transmits the carrier number allocation to the UE UE rule.

[0102] 每个UE的预设载波编号分配规则可以是预先配置在eNB上的,也可以是eNB分别和每个UE约定好的。 [0102] Default carrier number allocation rule for each UE may be preconfigured on the eNB, an eNB may be respectively and each UE-agreed.

[0103] 每个UE的载波编号分配规则可以相同,也可以不同。 [0103] No-carrier allocation rule for each UE may be the same or different.

[0104] 同样,每个UE的载波的编号可采用N(N为非负整数)比特二进制数字表示。 [0104] Similarly, the carrier may be employed for each UE ID N (N is a nonnegative integer) bit binary digital representation. [0105] “二「log/],其中,「]为向上取整运算符,M为UE的聚合载波集中的载波的频点数。 [0105] "Two" log /], where "] The ceil operators, M being the set of aggregated carriers UE carrier frequency points.

[0106] 编号分配规则可以如下: [0106] Item assignment rules may be as follows:

[0107] 规则一、按照UE的聚合载波集中的载波的频点的从小到大或者从大到小,依次将各个频点的载波编号为0、1、2、3........ [0107] a rule, in ascending or descending frequency polymeric carriers UE carrier set sequentially to each carrier frequency point numbered 0,1,2,3 ....... .

[0108] 规则二、按照eNB确定要在步骤202中发送给该UE的各个频点的顺序,依次将各 [0108] The second rule, in accordance with the eNB determines to be transmitted to the order of the frequency of the UE in step 202, each in turn

个频点的载波编号为0、1、2、3........例如:若UE的聚合载波集中的载波的频点为a、b、 Carrier number of frequency points 0,1,2,3 ........ example: polymeric carrier set for carrier frequency if the UE is a, b,

c、d,eNB确定在步骤202中将各载波的频点发送给UE的顺序为b、c、a、d,则频点b、c、a、 d的载波的编号分别为0、1、2、3。 c, d, eNB to the UE determines the order of transmission of each carrier frequency in the 202 step b, c, a, d, the frequency b, c, a, d of the carrier numbers are 0 and 1, 2,3.

[0109] 步骤202 :对于每个UE, eNB向该UE发送该UE的聚合载波集中的载波的频点。 [0109] Step 202: For each UE, eNB transmits to the UE the UE polymeric carrier concentration of the carrier frequency.

[0110] 本步骤中,eNB可以通过公共信令如:系统消息,也可通过专用控制信令将载波的频点发送给UE,公共信令或专用控制信令可以承载在RRC信令上。 [0110] In this step, the eNB may be as common signaling: system messages, dedicated control signaling can also be the carrier frequency is transmitted to the UE, common signaling or dedicated control signaling may be carried on the RRC signaling.

[0111] 步骤203 :UE接收并记录本UE的聚合载波集中的载波的频点。 [0111] Step 203: UE receives and records aggregated carrier frequency of the present set of carriers of the UE.

[0112] 步骤204 :eNB要在载波B上向UEl传送针对载波A的下行控制信令,在该下行控制信令中放入载波A的编号,将该下行控制信令承载在载波B上发送给UEl。 [0112] Step 204: eNB to the downlink control signaling for carrier A is placed on carrier B to UEl transmits the downlink control signaling number of carrier A, the bearer downlink control signaling transmitted on carrier B to UEl.

[0113] 步骤205 :UE1接收该下行控制信令,从该信令中读取载波A的编号,根据编号分配规则以及步骤203中记录的UEl的聚合载波集中的载波的频点,确定载波A的频点,在该频点对应的载波A上执行该下行控制信令中的内容。 [0113] Step 205: UE1 receives the downlink control signaling, A carrier number is read from the signaling in accordance with the allocation rule and the number recorded in step 203 UEl polymeric carrier set carrier frequency, the carrier A is determined frequency point, execution contents of the downlink control signaling on the carrier frequency corresponding to the point a.

[0114] 同样,在实际应用中,若每个UE的载波编号分配规则是预先由管理人员配置在eNB上的,则步骤201中,eNB也可不将每个UE的载波编号分配规则发送给对应的UE,而是在步骤202中将每个UE的分配规则连同该UE的聚合载波集中的载波的频点一起发送给对应的UE,或者,直接在步骤202中将每个UE的聚合载波集中的载波的频点和编号的对应关系发送给对应的UE。 [0114] Similarly, in practical applications, if the carrier number allocation rule for each UE in advance by the manager disposed on the eNB, then in step 201, the eNB may not transmit the carrier number is assigned to a corresponding rule for each UE the UE, but each UE transmits the allocation rule of step 202 will be polymerized together with the carrier concentration of the UE together with the carrier frequency to the corresponding UE, or directly to the carrier concentration in the polymerization in step 202 each UE It sends a corresponding relationship between the frequency and the number of carriers to the corresponding UE.

[0115] 若eNB在步骤202中将每个UE的载波编号分配规则连同该UE的聚合载波集中的载波的频点一起发送给对应的UE,则每个UE需要记录本UE的聚合载波集中的载波的频点和编号的对应关系,且,在步骤205中,UEl可直接根据该对应关系找到载波A的频点。 [0115] If the eNB transmits to the corresponding UE, together with the polymeric carrier set frequency carrier the UE ID in each carrier assignment rule in step 202 in the UE, each UE needs to record this UE aggregation carrier concentration of correspondence relationship between the carrier frequency and the number of points, and, in step 205, UEl a carrier frequency can be found directly based on the correspondence relationship.

[0116] 图1、2所示实施例中,是根据载波的频点为载波分配编号,在实际应用中,也可以根据载波的物理信道标识(PCI,Physical Channel Identifier)为载波分配编号,此时,需要将图1、2所示实施例中的“频点”都替换为“PCI”,同时,在步骤105中的“UE1从该信令中读取载波A的编号”之后,UEl需要与系统中的载波进行同步,以获得各载波的PCI ;在步骤205中的“UE1从该信令中读取载波A的编号”之后,UEl需要与UEl的聚合载波集中的载波进行同步,以获得各载波的PCI。 [0116] Figure 1 and 2 embodiment, are assigned numbers according to the carrier frequency of the carrier wave, in practical applications, the carrier may be assigned to the physical channel number of the carrier channel identifier (PCI, Physical Channel Identifier), this after, the embodiment shown in need of "frequency" in FIG. 2 are replaced with "the PCI", simultaneously, "the UE1 a carrier number is read from the signaling" in step 105, UEl need with carrier synchronization in the system, each carrier to obtain PCI; then in step 205 the "UE1 carrier a read from the signaling numbers", UEl need to synchronize with the carrier set UEL polymeric carrier to each carrier to obtain PCI.
