具体实施方式detailed description
下面结合附图及实施例对本公开再作进一步详细的描述。The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments.
目前,传统的动态调度方式中,终端通过发起随机接入流程与基站建立连接。基站在该流程中与UE协商并确定唯一的小区无线网络临时标识(C-RNTI,Cell-Radio NetworkT emporary Identifier),即确定无线资源调度的标识,并根据所述无线资源调度的标识向所述UE发送无线资源调度信息。然而,在免调度方式中,UE不发起随机接入流程,此时,如何获得唯一的C-RNTI,相关技术还没有给出相应的技术方案。Currently, in the traditional dynamic scheduling mode, a terminal establishes a connection with a base station by initiating a random access procedure. The base station negotiates with the UE in the process, and determines a unique Cell-Radio Network Identifier (C-RNTI), that is, determines an identifier of the radio resource scheduling, and according to the identifier of the radio resource scheduling, The UE sends radio resource scheduling information. However, in the scheduling-free mode, the UE does not initiate a random access procedure. In this case, how to obtain a unique C-RNTI, the related technology has not yet given a corresponding technical solution.
基于此,在本公开的各种实施例中:基站将UE ID的LSB作为无线资源调度的标识;根据所述无线资源调度的标识向所述UE发送无线资源调度信息;而对于UE,将UE ID的LSB作为无线资源调度的标识,根据所述无线资源调度的标识接收基站发送的无线资源调度信息。通过上述方式,UE能够在没有随机接入流程的情况下实现获取唯一的调度信息标识,并根据所述无线资源调度的标识接收基站发送的无线资源调度信息,进而后续能够接收到对应的下行业务信息。Based on this, in various embodiments of the present disclosure, the base station uses the LSB of the UE ID as the identifier of the radio resource scheduling; transmits the radio resource scheduling information to the UE according to the identifier of the radio resource scheduling; and for the UE, the UE The LSB of the ID is used as an identifier of the radio resource scheduling, and receives radio resource scheduling information sent by the base station according to the identifier of the radio resource scheduling. In the above manner, the UE can obtain the unique scheduling information identifier without the random access procedure, and receive the radio resource scheduling information sent by the base station according to the identifier of the radio resource scheduling, and then can receive the corresponding downlink service subsequently. information.
另外,所述UE ID的MSB被放置在MAC层的MAC CE中;所述MAC CE用于被所述UE确定接收到的下行数据是否为所述UE的下行数据,并通过匹配接收到MAC CE字段与自身的UE ID的MSB一致,判断接收到的数据为自己的数据,从而接收到对应的下行业务,如此,能够避免不同UE之间的冲突。In addition, the MSB of the UE ID is placed in the MAC CE of the MAC layer, and the MAC CE is used by the UE to determine whether the received downlink data is downlink data of the UE, and receives the MAC CE by matching. The field is consistent with the MSB of the UE ID of the UE, and the received data is determined to be its own data, so that the corresponding downlink service is received, and thus, conflicts between different UEs can be avoided.
实施例一Embodiment 1
本实施例调度信息传输方法,应用于基站,如图1所示,包括以下步骤:The scheduling information transmission method in this embodiment is applied to a base station, as shown in FIG. 1, and includes the following steps:
步骤101:基站将UE ID的LSB作为无线资源调度的标识;Step 101: The base station uses the LSB of the UE ID as an identifier of the radio resource scheduling.
换句话说,为UE分配无线资源调度的标识,分配的无线资源调度的标识为所述UE的UE ID的LSB。In other words, the UE is assigned an identifier of the radio resource scheduling, and the identifier of the allocated radio resource scheduling is an LSB of the UE ID of the UE.
这里,实际应用时,所述UE ID的MSB可以被放置在MAC层的MAC CE中;所述MAC CE用于供所述UE确定接收到的下行数据是否为所述UE的下行数据。Here, in actual application, the MSB of the UE ID may be placed in the MAC CE of the MAC layer; the MAC CE is used by the UE to determine whether the received downlink data is downlink data of the UE.
其中,UE ID的比特数为LSB和MSB的比特数之和。目前协议规定的UE ID长度为40比特,当LSB为16比特时,MSB为24比特。The number of bits of the UE ID is the sum of the number of bits of the LSB and the MSB. The length of the UE ID specified by the current protocol is 40 bits. When the LSB is 16 bits, the MSB is 24 bits.
当然,实际应用时,随着技术的发展,LSB的比特数是可以变化的,相应地,MSB、UE ID的比特数也是可以变化的。Of course, in actual application, as the technology develops, the number of bits of the LSB can be changed. Accordingly, the number of bits of the MSB and the UE ID can also be changed.
无线资源调度的标识,其作用是用来区分不同的UE,也就是说区分基站下发无线资源调度信息是哪个UE的。在一实施例中,无线资源调度的标识的长度可以为16比特,即取值范围为0~65535。这样设置无线资源调度的标识的长度的原因是:考虑到目前在一个小区下,接入UE的个数一般不会超过65536,在后续发展过程中,当接入UE的个数超过65536时,此时可以进一步扩展无线资源调度的标识的长度。The identifier of the radio resource scheduling is used to distinguish different UEs, that is, to distinguish which UE the radio resource scheduling information is sent by the base station. In an embodiment, the identifier of the radio resource scheduling may be 16 bits, that is, the value ranges from 0 to 65535. The reason for setting the length of the identifier of the radio resource scheduling is that the number of the accessing UEs does not exceed 65,536, and the number of the accessing UEs exceeds 65,536 in the subsequent development process. At this time, the length of the identifier of the radio resource scheduling can be further extended.
实际应用时,所述无线资源调度的标识可以是C-RNTI。In actual application, the identifier of the radio resource scheduling may be a C-RNTI.
步骤102:根据所述无线资源调度的标识向所述UE发送无线资源调度信息。Step 102: Send radio resource scheduling information to the UE according to the identifier of the radio resource scheduling.
具体地,采用分配的无线资源调度的标识加扰无线资源调度信息;Specifically, the radio resource scheduling information is scrambled by using the identifier of the allocated radio resource scheduling;
向所述UE发送加扰后的无线资源调度信息。The scrambled radio resource scheduling information is sent to the UE.
这里,所述无线资源调度信息为下行调度信息,下行调度信息可以是下行控制信息(DCI,Downlink Control Information),一般由物理下行控制信道(PDCCH,Physical Downlink Control Channel)承载。Here, the radio resource scheduling information is downlink scheduling information, and the downlink scheduling information may be Downlink Control Information (DCI), and is generally carried by a Physical Downlink Control Channel (PDCCH).
这里,实际应用时,放置所述UE MSB的MAC CE可以称为UE ID MAC CE。Here, in actual application, the MAC CE in which the UE MSB is placed may be referred to as a UE ID MAC CE.
具体地,如图2所示,所述UE的MSB放置在MAC层的协议数据单元(PDU)中的MAC CE中。Specifically, as shown in FIG. 2, the MSB of the UE is placed in a MAC CE in a Protocol Data Unit (PDU) of the MAC layer.
这里,还可以在MAC子头中携带LC ID,所述LC ID用于确定所述UE接收到的MAC CE是否携带所述UE的UE ID的MSB。Here, the LC ID may also be carried in the MAC sub-header, where the LC ID is used to determine whether the MAC CE received by the UE carries the MSB of the UE ID of the UE.
其中,LC ID具体格式如图3所示。实际应用时,LC ID索引可以为01110,对应的逻辑信道值可以为short UE ID。short UE ID指示所述UE的MAC CE。The specific format of the LC ID is shown in Figure 3. In actual application, the LC ID index may be 01110, and the corresponding logical channel value may be a short UE ID. The short UE ID indicates the MAC CE of the UE.
在一实施例中,向所述UE发送无线资源调度信息时,该方法可以包括:In an embodiment, when the radio resource scheduling information is sent to the UE, the method may include:
在寻呼子帧发送所述无线资源调度信息。Transmitting the radio resource scheduling information in a paging subframe.
在这种情况下,在当前寻呼子帧发送所述UE对应的下行数据。In this case, the downlink data corresponding to the UE is sent in the current paging subframe.
在一实施例中,向所述UE发送无线资源调度信息之前,该方法还可以包括:In an embodiment, before the sending the radio resource scheduling information to the UE, the method may further include:
在所述寻呼消息中携带第一信元,所述第一信元指示所述UE存在下行业务信息;Carrying, in the paging message, a first cell, where the first cell indicates that the UE has downlink service information;
在寻呼子帧下发所述寻呼消息。The paging message is sent in a paging subframe.
在这种情况下,向所述UE发送无线资源调度信息时,该方法还可以包括:In this case, when the radio resource scheduling information is sent to the UE, the method may further include:
在所述寻呼子帧后的第N个TTI到第N+M-1个TTI内向所述UE发送无线资源调度信息;N为大于或等于1的整数;M为大于或等于1的整数。Transmitting, by the Nth TTI to the N+M-1 TTIs after the paging subframe, radio resource scheduling information; N is an integer greater than or equal to 1; M is an integer greater than or equal to 1.
其中,实际应用时,还可以进一步利用寻呼消息指示所述UE对应的无线资源调度信息子帧与所述寻呼子帧之间的间隔。In an actual application, the paging message may be further used to indicate an interval between the radio resource scheduling information subframe corresponding to the UE and the paging subframe.
基于此,该方法还可以包括:Based on this, the method may further include:
在所述第一信元中携带一个字段,该字段指示所述UE对应的无线资源调度信息子帧与所述寻呼子帧之间的第一间隔;所述第一间隔为N个TTI。The first cell carries a field, where the field indicates a first interval between the radio resource scheduling information subframe corresponding to the UE and the paging subframe; the first interval is N TTIs.
在一实施例中,向所述UE发送无线资源调度信息之前收到所述UE的上行业务数据;在向所述UE发送无线资源调度信息之前,该方法还可以包括:In an embodiment, before the sending the radio resource scheduling information to the UE, the uplink service data of the UE is received; before the sending the radio resource scheduling information to the UE, the method may further include:
在所述寻呼消息中携带第二信元,所述第二信元指示所述UE上行数据子帧与下行调度信息子帧之间的第二间隔;第二间隔为L个TTI;The second message includes a second cell, where the second cell indicates a second interval between the UE uplink data subframe and the downlink scheduling information subframe; the second interval is L TTIs;
在寻呼子帧下发所述寻呼消息。The paging message is sent in a paging subframe.
这里,实际应用时,所述第二间隔也可以采用规定的方式。Here, in actual application, the second interval may also be in a prescribed manner.
这种情况下,向所述UE发送无线资源调度信息之前收到所述UE的上行业务数据;向所述UE发送无线资源调度信息时,该方法可以包括:In this case, the uplink service data of the UE is received before the radio resource scheduling information is sent to the UE; when the radio resource scheduling information is sent to the UE, the method may include:
在上行数据子帧后的第L个TTI到第L+M-1个TTI内发送所述无线资源调度信息;L为大于或等于1的整数;M为大于或等于1的整数。Transmitting the radio resource scheduling information in the Lth TTI to the L+M-1 TTIs after the uplink data subframe; L is an integer greater than or equal to 1; M is an integer greater than or equal to 1.
在一实施例中,该方法还可以包括:In an embodiment, the method may further include:
向所述UE发送下行数据。Sending downlink data to the UE.
具体地,利用所述无线资源调度信息所对应的资源向所述UE发送下行数据。Specifically, the downlink data is sent to the UE by using resources corresponding to the radio resource scheduling information.
对应地,所述UE需要获取无线资源调度的标识,以便能获取到给自身下发的无线资源调度信息。Correspondingly, the UE needs to obtain the identifier of the radio resource scheduling, so that the radio resource scheduling information delivered to itself can be obtained.
基于此,本实施例还提供了一种调度信息传输方法,应用于UE,如图4所示,该方法包括以下步骤:Based on this, the embodiment further provides a scheduling information transmission method, which is applied to the UE. As shown in FIG. 4, the method includes the following steps:
步骤401:将UE ID的LSB作为无线资源调度的标识;Step 401: The LSB of the UE ID is used as an identifier of the radio resource scheduling.
这里,实际应用时,所述UE可以通过匹配接收到MAC CE字段与自身的UE ID的MSB一致,判断接收到的数据为自己的数据。Here, in actual application, the UE may determine that the received data is its own data by matching the received MS CE field with the MSB of its own UE ID.
其中,当匹配接收到MAC CE字段与自身的UE ID的MSB不一致时,所述UE确定接收到的数据不为自己的数据。The UE determines that the received data is not its own data when the matching MSB field does not match the MSB of its own UE ID.
这里,所述UE使用无线资源调度的标识应当与基站采用的无线资源的标识相同。Here, the identifier of the radio resource scheduling used by the UE should be the same as the identifier of the radio resource used by the base station.
步骤402:根据所述无线资源调度的标识接收基站发送的无线资源调度信息。Step 402: Receive radio resource scheduling information sent by the base station according to the identifier of the radio resource scheduling.

在实施例一的基础上,本实施例描述基站(演进型节点B(eNB))在 寻呼子帧时刻直接调度下行数据的过程。Based on the first embodiment, this embodiment describes a process in which a base station (evolved Node B (eNB)) directly schedules downlink data at a paging subframe time.
本实施例描述的应用场景是:UE处于演进的分组系统连接管理空闲(ECM-IDLE,EPS Connection Management IDLE)状态。处于ECM-IDLE状态的UE,每个UE有唯一的UE ID。The application scenario described in this embodiment is that the UE is in an evolved EPC-IDLE (EPS Connection Management IDLE) state. UEs in the ECM-IDLE state, each UE has a unique UE ID.
如图5所示,该过程包括以下步骤:As shown in Figure 5, the process includes the following steps:
步骤501:下行业务数据或者信令到达基站;Step 501: The downlink service data or signaling arrives at the base station.
这里,当下行业务数据或者信令到达基站后,基站需要判断何时下发无线资源调度信息。Here, after the downlink service data or signaling arrives at the base station, the base station needs to determine when to issue the radio resource scheduling information.
具体地,由于UE处于ECM-IDLE状态,无法判断基站在哪个TTI下发了对应的无线资源调度信息。因此基站需要选择合适的调度机会,下发对应的调度信息。Specifically, since the UE is in the ECM-IDLE state, it is impossible to determine which TTI the base station sends the corresponding radio resource scheduling information. Therefore, the base station needs to select an appropriate scheduling opportunity and deliver corresponding scheduling information.
步骤502:基站在PO向UE发送无线资源调度信息;Step 502: The base station sends radio resource scheduling information to the UE at the PO.
在本实施例中,基站可以在寻呼(Paging)周期内的某个特定帧(该特定帧称为寻呼帧(PF,Paging Frame))的特定子帧(该特定子帧在以下的描述中称为寻呼子帧,被命名为寻呼时刻(PO,Paging Occasion))发送下行调度信息。In this embodiment, the base station may be in a specific subframe of a specific frame (referred to as a paging frame (PF) in the paging period) (the specific subframe is described below). The paging subframe is called a paging time (PO, Paging Occasion) to transmit downlink scheduling information.

步骤504:UE收到下行调度信息后,解析对应的下行调度信息;Step 504: After receiving the downlink scheduling information, the UE parses the corresponding downlink scheduling information.
具体地,UE使用无线资源调度的标识(在本实施例中可以理解为C-RNTI)解析PDCCH。其中,C-RNTI为UE ID的LSB(16bits)。Specifically, the UE parses the PDCCH using the identifier of the radio resource scheduling (which may be understood as C-RNTI in this embodiment). The C-RNTI is the LSB (16 bits) of the UE ID.
需要说明的是,对于UE在哪个时刻接收paging,本公开实施例不做特殊说明。UE会在其Paging周期内的PF的每个PO都尝试解析下行调度信息。It should be noted that, at which time the UE receives the paging, the embodiment of the present disclosure does not specifically describe. The UE will attempt to parse the downlink scheduling information for each PO of the PF in its Paging period.
步骤505:UE解析对应的下行空口数据;Step 505: The UE parses the corresponding downlink air interface data.
具体地,UE根据PDCCH信息接收下行空口数据(由PDSCH承载),例如,根据PDCCH中指示的物理资源、MCS等用于接收PDSCH的信息来接收并解码下行空口数据,并判断是否成功解码。Specifically, the UE receives the downlink air interface data (beared by the PDSCH) according to the PDCCH information, for example, receives and decodes the downlink air interface data according to the physical resource, the MCS, and the like for receiving the PDSCH, and determines whether the decoding is successful.
这里,实际应用时下行空口数据以数据块的方式传输。Here, the downlink air interface data is transmitted in the form of data blocks in actual application.
步骤506:在解码成功后,UE将接收到的下行数据信息投递给上层协议层即MAC层进行处理;Step 506: After the decoding succeeds, the UE delivers the received downlink data information to the upper layer protocol layer, that is, the MAC layer for processing;
步骤507:UE MAC层判断所获取的MAC CE字段与自身的UE ID的MSB是否一致,如果一致,则认为接收到的数据为自己的数据,继续执行步骤508;否则,丢弃该数据,执行步骤509;Step 507: The UE MAC layer determines whether the acquired MAC CE field is consistent with the MSB of its own UE ID. If the data is consistent, the received data is considered to be its own data, and the process proceeds to step 508; otherwise, the data is discarded, and the steps are performed. 509;

Therefore, the base station needs to select an appropriate scheduling opportunity and deliver corresponding scheduling information.
步骤602:基站在寻呼子帧下发Paging消息,并在当前寻呼帧内最后一个寻呼子帧后的N个TTI发送所述UE的无线资源调度信息;Step 602: The base station sends a Paging message in the paging subframe, and sends the radio resource scheduling information of the UE in the N TTIs after the last paging subframe in the current paging frame.

The Nth TTI after the last paging subframe (ie, PO) in the frame sends downlink scheduling information.
其中,实际应用时,寻呼子帧与发送下行调度信息子帧之间的间隔(N个TTI)是预先规定的。The actual interval between the paging subframe and the downlink scheduling information subframe (N TTIs) is predetermined.
具体地,基站在Paging消息中携带一个信元,该信元与寻呼列表(PagingRecordList)中的UE对应,指示PagingRecordList中的某些UE在协议规定的当前PF内最后一个寻呼子帧(即PO)后的第4(举例说明N=4)个TTI开始,基站会发送对应的下行调度信息。Specifically, the base station carries a cell in the Paging message, and the cell corresponds to the UE in the paging list (PagingRecordList), and indicates that some UEs in the PagingRecordList are in the last paging subframe in the current PF specified by the protocol (ie, The fourth (after N=4) TTIs after PO) starts, and the base station sends corresponding downlink scheduling information.

The downlink scheduling information may be a DCI carried by the PDCCH.
PDCCH中可以包含物理资源指示、MCS等用于接收PDSCH(承载下行数据信息)的信息。The PDCCH may include physical resource indication, MCS, and the like for receiving PDSCH (bearing downlink data information).

具体地,UE在接收到paging消息后需识别当前PF的最后一个寻呼子帧。当下行调度信息为PDCCH信息时,UE从当前PF的最后一个寻呼子帧的第N个TTI到第N+M-1个TTI使用无线资源调度的标识(在本实施例中可以理解为C-RNTI)解析PDCCH。其中M表示UE盲检测PDCCH的窗口为M个TTI。其中,C-RNTI为UE ID的LSB(16bits)。Specifically, the UE needs to identify the last paging subframe of the current PF after receiving the paging message. When the downlink scheduling information is the PDCCH information, the UE uses the identifier of the radio resource scheduling from the Nth TTI to the N+M-1 TTIs of the last paging subframe of the current PF (in this embodiment, it can be understood as C). - RNTI) Parses the PDCCH.

步骤605:UE解析对应的下行空口数据;Step 605: The UE parses the corresponding downlink air interface data.
具体地,UE根据PDCCH信息接收下行空口数据(由PDSCH承载),例如,根据PDCCH中指示的物理资源、MCS等用于接收PDSCH的信息来接收并解码下行空口数据,并判断是否成功解码。Specifically, the UE receives the downlink air interface data (beared by the PDSCH) according to the PDCCH information, for example, receives and decodes the downlink air interface data according to the physical resource, the MCS, and the like for receiving the PDSCH, and determines whether the decoding is successful.

Therefore, the base station needs to select an appropriate scheduling opportunity and deliver corresponding scheduling information.
步骤702:基站在寻呼子帧下发Paging消息,并在当前PF内最后一个寻呼子帧后的N个TTI发送所述UE的无线资源调度信息;Step 702: The base station sends a Paging message in the paging subframe, and sends the radio resource scheduling information of the UE in the N TTIs after the last paging subframe in the current PF.

The cell notifies a UE in the PagingRecordList that the interval between the paging subframe and the base station transmitting the downlink scheduling information subframe is 3 TTIs; the cell simultaneously notifies another UE in the PagingRecordList, and the paging subframe is sent by the base station. The interval between downlink scheduling information subframes is 4 TTIs.

对于上述例子,UE在Paging消息中解析到存在下行业务的信元后,判断当前PF的最后一个寻呼子帧(即PO),并在最后一个寻呼子帧(即PO)后的3至(3+6-1)个TTI解码对应的C-RNTI加扰的下行调度信息(即PDCCH),根据PDCCH中指示的物理资源、MCS等用于接收PDSCH的信息来接收并解码下行空口数据,并判断是否成功解码。另外针对寻呼列表 中的另一个UE可以在最后一个寻呼子帧(即PO)后的4至(4+6-1)个TTI解码对应的C-RNTI加扰的下行调度信息(即PDCCH)。For the above example, after parsing the cell with the downlink service in the Paging message, the UE determines the last paging subframe (ie, PO) of the current PF, and 3 to 3 after the last paging subframe (ie, PO). (3+6-1) TTI decoding corresponding C-RNTI scrambled downlink scheduling information (ie, PDCCH), receiving and decoding downlink air interface data according to physical resources, MCS, and the like used for receiving the PDSCH indicated in the PDCCH, And determine whether the decoding is successful. In addition, another UE in the paging list may decode the corresponding C-RNTI scrambled downlink scheduling information (ie, PDCCH) from 4 to (4+6-1) TTIs after the last paging subframe (ie, PO). ).
步骤706:在解码成功后,UE将接收到的下行数据信息投递给上层协议层即MAC层进行处理;Step 706: After the decoding succeeds, the UE delivers the received downlink data information to the upper layer protocol layer, that is, the MAC layer for processing;

If the data is consistent, the received data is considered to be its own data, and the process proceeds to step 708; otherwise, the data is discarded, and the steps are performed. 709;
这里,本步骤中MAC CE字段为UE ID MAC CE字段。Here, the MAC CE field in this step is the UE ID MAC CE field.
步骤708:UE MAC层解析PDU中的所述UE的MAC SDU,投递给上层协议层,即RLC层/PDCP处理,后续流程和目前协议保持一致;Step 708: The UE MAC layer parses the MAC SDU of the UE in the PDU, and delivers it to the upper layer protocol layer, that is, the RLC layer/PDCP processing, and the subsequent process is consistent with the current protocol.

实施例五Embodiment 5
在实施例一的基础上,本实施例描述调度上行业务触发的下行业务,就是基站在收到上行业务的反馈信息后的L个TTI后传输对应的下行业务的过程。On the basis of the first embodiment, the following describes the process of scheduling the downlink service triggered by the uplink service, which is the process of transmitting the corresponding downlink service after the LTIs of the base station after receiving the feedback information of the uplink service.
其中L的取值可以通过paging消息中携带信元指示,也可以为规定的取值。The value of L may be indicated by a cell carrying a paging message, or may be a specified value.
本实施例描述的应用场景是:UE处于ECM-IDLE状态。处于ECM-IDLE状态的UE,每个UE有唯一的UE ID。The application scenario described in this embodiment is that the UE is in the ECM-IDLE state. UEs in the ECM-IDLE state, each UE has a unique UE ID.
如图8所示,该过程包括以下步骤:As shown in Figure 8, the process includes the following steps:
步骤801:下行业务数据或者信令到达基站;Step 801: The downlink service data or signaling arrives at the base station.
这里,当下行业务数据或者信令到达基站后,基站需要判断何时下发调度信息。Here, after the downlink service data or signaling arrives at the base station, the base station needs to determine when to issue the scheduling information.
具体地,由于UE处于ECM-IDLE状态,无法判断基站在哪个TTI下发了对应的无线资源调度信息。因此基站需要选择合适的调度机会,下发对应的调度信息。Specifically, since the UE is in the ECM-IDLE state, it is impossible to determine which TTI the base station sends the corresponding radio resource scheduling information. Therefore, the base station needs to select an appropriate scheduling opportunity and deliver corresponding scheduling information.
步骤802:基站在收到UE上行数据后L个TTI向UE传输无线资源调度信息;Step 802: The base station transmits the radio resource scheduling information to the UE after receiving the uplink data of the UE.
具体地,基站在收到UE的上行业务后,在L个TTI后下发对应的下行调度信息,即在收到UE上行业务后的第L个TTI开始到第L+M-1个TTI内下发对应的下行调度信息。Specifically, after receiving the uplink service of the UE, the base station sends the corresponding downlink scheduling information after the L TTIs, that is, after the Lth TTI after receiving the uplink service of the UE starts to the L+M-1 TTIs. The corresponding downlink scheduling information is delivered.
这里,实际应用时N的取值是预先规定的。比如,规定基站在收到UE的上行业务后4个TTI下发对应的下行调度信息。Here, the value of N in the actual application is predetermined. For example, the base station is configured to deliver corresponding downlink scheduling information by using four TTIs after receiving the uplink service of the UE.
这里,无线资源调度信息为采用无线资源调度的标识加扰的下行调度信息(在以下的描述中称为下行调度信息)。下行调度信息可以是PDCCH所承载的DCI。Here, the radio resource scheduling information is downlink scheduling information (referred to as downlink scheduling information in the following description) scrambled by the identifier of the radio resource scheduling. The downlink scheduling information may be a DCI carried by the PDCCH.
PDCCH中可以包含指示的物理资源指示、MCS等用于接收PDSCH(承载下行数据信息)的信息。The PDCCH may include the indicated physical resource indication, the MCS, and the like for receiving the PDSCH (bearing downlink data information).
其中,无线资源调度的标识为UE ID的LSB,LSB为16bits,UE ID的MSB放置在对应的UE ID MAC CE中下发。The identifier of the radio resource scheduling is the LSB of the UE ID, and the LSB is 16 bits. The MSB of the UE ID is placed and sent in the corresponding UE ID MAC CE.
步骤803:基站在所述物理资源指示的物理资源上采用所述MCS发送下行空口数据;Step 803: The base station sends the downlink air interface data by using the MCS on the physical resource indicated by the physical resource.
步骤804:UE收到下行调度信息后,解析对应的下行调度信息;Step 804: After receiving the downlink scheduling information, the UE parses the corresponding downlink scheduling information.
具体地,UE在发送数据信息后的第L个TTI开始到第L+M-1个TTI,使用无线资源调度的标识(在本实施例中可以理解为C-RNTI)解析PDCCH。其中M表示UE盲检测PDCCH的窗口为M个TTI。Specifically, the UE starts to the L+M-1 TTIs after transmitting the data information, and parses the PDCCH using the identifier of the radio resource scheduling (which can be understood as C-RNTI in this embodiment). Where M indicates that the window for the UE to blindly detect the PDCCH is M TTIs.
其中,C-RNTI为UE ID的LSB(16bits)。The C-RNTI is the LSB (16 bits) of the UE ID.
步骤805:UE解析对应的下行空口数据;Step 805: The UE parses the corresponding downlink air interface data.
具体地,UE根据PDCCH信息接收下行空口数据(由PDSCH承载),例如,根据PDCCH中指示的物理资源、MCS等用于接收PDSCH的信息来接收并解码下行空口数据,并判断是否成功解码。Specifically, the UE receives the downlink air interface data (beared by the PDSCH) according to the PDCCH information, for example, receives and decodes the downlink air interface data according to the physical resource, the MCS, and the like for receiving the PDSCH, and determines whether the decoding is successful.
这里,实际应用时下行空口数据以数据块的方式传输。其中PDCCH与PDSCH之间的定时关系,本实施例不做特殊说明。Here, the downlink air interface data is transmitted in the form of data blocks in actual application. The timing relationship between the PDCCH and the PDSCH is not specifically described in this embodiment.
举例来说,UE在发送上行数据后第6个TTI到第6+4-1=9个TTI解码 对应的C-RNTI加扰的下行调度信息。此时,L取值为6,M取值为4。For example, the UE transmits the uplink data from the 6th TTI to the 6th 4-1=9 TTIs to decode the corresponding C-RNTI scrambled downlink scheduling information. At this time, L is 6 and M is 4.
步骤806:在解码成功后,UE将接收到的下行数据信息投递给上层协议层即MAC层进行处理;Step 806: After the decoding succeeds, the UE delivers the received downlink data information to the upper layer protocol layer, that is, the MAC layer for processing;
步骤807:UE MAC层判断所获取的MAC CE字段与自身的UE ID的MSB是否一致,如果一致,则认为接收到的数据为自己的数据,继续执行步骤808;否则,丢弃该数据,执行步骤809;Step 807: The UE MAC layer determines whether the acquired MAC CE field is consistent with the MSB of its own UE ID. If the data is consistent, the received data is considered to be its own data, and the process proceeds to step 808; otherwise, the data is discarded, and the steps are performed. 809;
这里,本步骤中MAC CE字段为UE ID MAC CE字段。Here, the MAC CE field in this step is the UE ID MAC CE field.
步骤808:UE MAC层解析PDU中的所述UE的MAC SDU,投递给上层协议层,即RLC层/PDCP处理,后续流程和目前协议保持一致。Step 808: The UE MAC layer parses the MAC SDU of the UE in the PDU, and delivers it to the upper layer protocol layer, that is, the RLC layer/PDCP processing, and the subsequent process is consistent with the current protocol.
步骤809:结束当前处理流程。Step 809: End the current processing flow.
需要说明的是:实施例二至四仅描述了下行数据新传过程中调度信息的传输过程。实际应用时,下行调度也涉及到重传过程,且重传的优先级高于新传的优先级。重传的调度方式可参考新传的调度方式,这里不再赘述。It should be noted that Embodiments 2 to 4 only describe the transmission process of scheduling information in the process of downlink data transmission. In practical applications, the downlink scheduling also involves the retransmission process, and the retransmission priority is higher than the new transmission priority. The scheduling mode of the retransmission can refer to the scheduling mode of the new transmission, which will not be described here.
实施例六Embodiment 6
为实现本公开实施例的方法,本实施例提供一种调度信息传输装置,设置在基站上,如图9所示,该装置包括:To implement the method of the embodiment of the present disclosure, the embodiment provides a scheduling information transmission apparatus, which is disposed on a base station. As shown in FIG. 9, the apparatus includes:
第一分配单元91,配置为将UE ID的LSB作为无线资源调度的标识;The first allocating unit 91 is configured to use an LSB of the UE ID as an identifier of the radio resource scheduling.
发送单元92,配置为根据所述无线资源调度的标识向所述UE发送无线资源调度信息。The sending unit 92 is configured to send the radio resource scheduling information to the UE according to the identifier of the radio resource scheduling.
也就是说,所述第一分配单元91为UE分配无线资源调度的标识;分配的无线资源调度的标识为所述UE的UE ID的LSB。That is, the first allocating unit 91 allocates an identifier of the radio resource scheduling to the UE; the identifier of the allocated radio resource scheduling is an LSB of the UE ID of the UE.
这里,实际应用时,所述UE ID的MSB可以被放置在MAC层的MAC CE中;所述MAC CE用于供所述UE确定接收到的下行数据是否为所述UE的下行数据。Here, in actual application, the MSB of the UE ID may be placed in the MAC CE of the MAC layer; the MAC CE is used by the UE to determine whether the received downlink data is downlink data of the UE.
其中,UE ID的比特数为LSB和MSB的比特数之和。目前协议规定的 UE ID长度为40比特,当LSB为16比特时,MSB为24比特。The number of bits of the UE ID is the sum of the number of bits of the LSB and the MSB. The length of the UE ID specified by the current protocol is 40 bits. When the LSB is 16 bits, the MSB is 24 bits.
当然,实际应用时,随着技术的发展,LSB的比特数是可以变化的,相应地,MSB、UE ID的比特数也是可以变化的。Of course, in actual application, as the technology develops, the number of bits of the LSB can be changed. Accordingly, the number of bits of the MSB and the UE ID can also be changed.
无线资源调度的标识,其作用是用来区分不同的UE,也就是说区分无线资源调度信息是哪个UE的。在一实施例中,无线资源调度的标识的长度可以为16比特,即取值范围为0~65535。这样设置无线资源调度的标识的长度的原因是:考虑到目前在一个小区下,接入UE的个数一般不会超过65536,在后续发展过程中,当接入UE的个数超过65536时,此时可以进一步扩展无线资源调度的标识的长度。The identifier of the radio resource scheduling is used to distinguish different UEs, that is, to distinguish which UE the radio resource scheduling information is. In an embodiment, the identifier of the radio resource scheduling may be 16 bits, that is, the value ranges from 0 to 65535. The reason for setting the length of the identifier of the radio resource scheduling is that the number of the accessing UEs does not exceed 65,536, and the number of the accessing UEs exceeds 65,536 in the subsequent development process. At this time, the length of the identifier of the radio resource scheduling can be further extended.
实际应用时,所述无线资源调度的标识可以是C-RNTI。In actual application, the identifier of the radio resource scheduling may be a C-RNTI.
所述发送单元92,配置为:The sending unit 92 is configured to:
采用分配的无线资源调度的标识加扰无线资源调度信息;The radio resource scheduling information is scrambled by using the identifier of the allocated radio resource scheduling;

所述无线资源调度信息为下行调度信息,下行调度信息可以是DCI,一般由PDCCH承载。The radio resource scheduling information is downlink scheduling information, and the downlink scheduling information may be DCI, and is generally carried by the PDCCH.
这里,实际应用时,放置所述UE MSB的MAC CE可以称为UE ID MAC CE。Here, in actual application, the MAC CE in which the UE MSB is placed may be referred to as a UE ID MAC CE.
对于所述UE的MSB,如图2所示,所述UE的MSB放置在MAC层的PDU中的MAC CE中。For the MSB of the UE, as shown in FIG. 2, the MSB of the UE is placed in the MAC CE in the PDU of the MAC layer.
实际应用时,还可以在MAC子头中增加LC ID,所述LC ID用于确定所述UE接收到的MAC CE是否携带所述UE的UE ID的MSB。In an actual application, the LC ID may be added to the MAC sub-header, where the LC ID is used to determine whether the MAC CE received by the UE carries the MSB of the UE ID of the UE.
其中,增加的LC ID具体格式如图3所示,LC ID索引为01110,对应的逻辑信道值为short UE ID。short UE ID指示所述UE的MAC CE。The specific format of the added LC ID is shown in FIG. 3, the LC ID index is 01110, and the corresponding logical channel value is a short UE ID. The short UE ID indicates the MAC CE of the UE.
基于此,该装置还可以包括:Based on this, the device may further include:
