Description

调度无线资源的方法、 网络设备和用户设备 技术领域  Method for scheduling wireless resources, network device and user equipment
本发明涉及通信领域, 尤其涉及通信领域中调度无线资源的方法、 网络 设备和用户设备。 背景技术  The present invention relates to the field of communications, and in particular, to a method, a network device, and a user equipment for scheduling radio resources in the communication field. Background technique
在诸如长期演进( Long Term Evolution , 筒称为 "LTE" ) 系统的通信系 统中, 演进型基站( evolved Node B , 筒称为 "eNB或 e-NodeB" )向用户设 备(User Equipment, 筒称为 "UE" )发送动态调度信令, UE就可以根据该 动态调度信令相应地进行数据的接收或发送, 其中, 动态调度信令中包括 eNB为 UE调度的频带、 以及使用的调制编码方案 (Modulation and Coding Scheme, 筒称为 "MCS" )等信息。 应理解, eNB也可以向 UE发送半静态 调度信令, 如果 UE收到半静态调度信令, 则 UE在下一次收到新的调度信 令之前, 会一直根据该半静态调度信令进行数据的传输; 而如果 UE收到动 态调度信令, 则 UE只会根据该动态调度信令进行有限几次的数据传输。  In a communication system such as a Long Term Evolution (LTE) system, an evolved base station (evolved Node B, referred to as "eNB or e-NodeB") is addressed to a user equipment (User Equipment). The dynamic scheduling signaling is sent to the UE, and the UE may receive or send data according to the dynamic scheduling signaling, where the dynamic scheduling signaling includes a frequency band scheduled by the eNB for the UE, and a modulation and coding scheme used. (Modulation and Coding Scheme, the tube is called "MCS") and other information. It should be understood that the eNB may also send semi-persistent scheduling signaling to the UE. If the UE receives semi-persistent scheduling signaling, the UE will always perform data according to the semi-persistent scheduling signaling before receiving the new scheduling signaling for the next time. If the UE receives dynamic scheduling signaling, the UE will only perform limited data transmission according to the dynamic scheduling signaling.
例如, 在 LTE系统中, 系统频带以子载波为最小粒度被划分, 并且一个 物理资源块(Physical Resource Block, 筒称为 "PRB" ) 包括 12个子载波, 如果 eNB向 UE发送动态调度信令, 为 UE的下行传输分配编号为 4~6的 PRB , 则 UE就可以相应地在对应的频带上接收物理上行共享信道 ( Physical Uplink Shared Channel, 筒称为 "PUSCH" ), 从而 UE可以根据该动态调度 信令相应地进行数据的接收或发送。  For example, in the LTE system, the system frequency band is divided into sub-carriers with a minimum granularity, and one physical resource block (Physical Resource Block, referred to as "PRB") includes 12 sub-carriers. If the eNB sends dynamic scheduling signaling to the UE, The UE may receive a physical uplink shared channel (Physical Uplink Shared Channel, called "PUSCH") in the corresponding frequency band, so that the UE can respond to the dynamic downlink shared channel ("PUSCH") in the corresponding frequency band. The scheduling signaling performs data reception or transmission accordingly.
在目前的技术中, 网络设备通常根据调度之前获取的无线环境的信息, 包括无线信道和干扰等信息(例如信干噪比( Signal to Interference-plus-Noise Ratio , 筒称为 "SINR" ) ), 确定对 UE的调度方案, 从而能够使调度方案匹 配无线环境,并且当调度方案确定之后,该调度方案在本次调度中不能更改。 然而, 无线环境的波动可能较大, 因此网络设备一次性确定的调度方案不一 定适合实际传输数据信号时的无线环境, 从而可能降低信号传输的可靠性。 发明内容  In the current technology, the network device usually receives information such as a wireless channel and interference according to the information of the wireless environment acquired before scheduling (for example, Signal to Interference-plus-Noise Ratio ("SINR") Determining a scheduling scheme for the UE, so that the scheduling scheme can be matched to the wireless environment, and the scheduling scheme cannot be changed in the current scheduling after the scheduling scheme is determined. However, the fluctuation of the wireless environment may be large, so the scheduling scheme determined by the network device at one time is not necessarily suitable for the wireless environment when the data signal is actually transmitted, thereby possibly reducing the reliability of signal transmission.

The uplink data signal sent by the first user equipment according to the second dynamic scheduling signaling of the first user equipment.
为了提高信号传输的可靠性, 网络设备可以先向用户设备发送包括频率 信息和索引信息的第一动态调度信令, 其中该频率信息用于指示频率资源, 该索引信息用于指示承载第二动态调度信令的信息位; 网络设备随后可以在 该索引信息指示的该信息位上向用户设备发送该用户设备的第二动态调度 信令; 对于下行传输而言, 网络设备在该频率信息所对应的频率资源上、 根 据该用户设备的第二动态调度信令向该用户设备发送下行数据信号, 或者对 于上行传输而言, 网络设备在所述频率信息所对应的频率资源上, 接收该用 户设备根据该第二动态调度信令发送的上行数据信号。  In order to improve the reliability of the signal transmission, the network device may first send the first dynamic scheduling signaling including the frequency information and the index information to the user equipment, where the frequency information is used to indicate the frequency resource, and the index information is used to indicate that the second dynamic is carried.

因此, 本发明实施例的调度无线资源的方法, 通过采用两个动态调度信 令为用户设备调度上行或下行资源, 能够使得调度方案更好地适应信道环境 的变化, 从而能够提高信号传输的可靠性, 提高用户体验。  Therefore, the method for scheduling radio resources in the embodiment of the present invention can use the two dynamic scheduling signaling to schedule uplink or downlink resources for the user equipment, so that the scheduling scheme can better adapt to changes in the channel environment, thereby improving signal transmission reliability. Sex, improve the user experience.
另一方面, 网络设备在第一动态调度信令中还承载第二动态调度信令中 的信息的索引, 便于网络设备动态地向被调度的 UE指示发送第二动态调度 信令所使用的信息位, 从而能够充分利用有限的信息位来满足为多个 UE的 调度, 以降低动态调度信令所需要的信息位资源开销, 提高资源利用率。  On the other hand, the network device further carries an index of the information in the second dynamic scheduling signaling in the first dynamic scheduling signaling, so that the network device dynamically indicates to the scheduled UE that the information used by the second dynamic scheduling signaling is sent. The bit can be used to fully utilize the limited information bits to satisfy the scheduling for multiple UEs, so as to reduce the information bit resource overhead required for dynamic scheduling signaling and improve resource utilization.
下面将结合目前的调度方案,对根据本发明实施例的调度无线资源的方 法进行具体描述。  The method for scheduling radio resources according to an embodiment of the present invention will be specifically described below in conjunction with the current scheduling scheme.
在采用了多载波技术的 LTE系统中, 一个传输时间间隔(Transmission Time Interval,筒称为 "ΤΤΓ )的长度通常包括 14个正交频分复用( Orthogonal Frequency Division Multiplexing, 筒称为 "OFDM" )符号, 对于下行传输而 言, 其中前 Nc ( Nc为自然数且小于或等于 14 )个符号可被用于传输物理下 行控制信道 ( Physical Downlink Control Channel, 筒称为 "PDCCH" )信号, 以向 UE发送下行动态调度信令, 其它符号用于传输物理下行共享信道 ( Physical Downlink Shared Channel, 筒称为 "PDSCH" )信号(数据信号)。  In an LTE system employing multi-carrier technology, a transmission time interval (transmission time Interval, referred to as "ΤΤΓ" length usually includes 14 orthogonal frequency division multiplexing ("Orthogonal Frequency Division Multiplexing") The symbol, for the downlink transmission, where the pre-Nc (Nc is a natural number and less than or equal to 14) symbols can be used to transmit a Physical Downlink Control Channel ("SCH") signal to The UE sends downlink dynamic scheduling signaling, and other symbols are used to transmit a Physical Downlink Shared Channel ("PDSCH") signal (data signal).
对于编号为 n 的 ΤΉ, 网络设备可以在前 Nc 个符号中向 UE发送 For 编号 number n, the network device can send the UE to the UE in the first Nc symbols.
PDCCH, 其中包括频率资源信息和 MCS信息等, 并可以根据该频率资源信 息和 MCS信息,在相应频率资源上、使用该 MCS所对应的编码速率和调制 方式来处理发送给 UE 的信息并生成 PDSCH信号, 最后可以向 UE发送 PDSCH信号。 UE可以首先从 Nc个符号中检测 PDCCH信号 (后面筒称 PDCCH ), 从中获取频率资源信息和 MCS信息, 并可以根据该频率资源信 息确定发给自己的 PDSCH所在的频率, 从而获取 PDSCH信号 (后面筒称 PDSCH ), 由此 UE可以根据该 MCS信息对收到的 PDSCH信号进行解调和 解码。 PDCCH, including frequency resource information, MCS information, etc., and may be based on the frequency resource letter And the MCS information, processing the information sent to the UE and generating the PDSCH signal on the corresponding frequency resource, using the coding rate and modulation mode corresponding to the MCS, and finally transmitting the PDSCH signal to the UE. The UE may first detect a PDCCH signal (hereinafter referred to as a PDCCH) from the Nc symbols, obtain frequency resource information and MCS information therefrom, and determine a frequency of the PDSCH sent to itself according to the frequency resource information, thereby acquiring a PDSCH signal (behind The cartridge is called PDSCH), whereby the UE can demodulate and decode the received PDSCH signal according to the MCS information.
例如, 若 Nc=2, 则网络设备可以在前 2个符号向 UE发送 PDCCH, 其 中指示为 UE分配了编号为 5~8的 PRB, 并指示采用了调制方式为 16正交 幅度调制 ( 16- Quadrature Amplitude Modulation, 筒称为 "16QAM" )、 编码 速率为 1/2的 MCS; 网络设备可以再根据这些信息, 在编号为 5~8的 PRB 上、 使用调制方式为 16QAM、 编码速率为 1/2的 MCS, 对发送给 UE的数 据进行编码和调制, 从而生成 PDSCH, 并可以通过该 ΤΉ的其它 12个符号 发送出去。 UE可以首先在前 2个符号上接收 PDCCH,获取频率信息和 MCS 信息, 再根据该频率信息和 MCS信息来接收 PDSCH。  For example, if Nc=2, the network device may send a PDCCH to the UE in the first 2 symbols, where the UE is assigned a PRB numbered 5-8, and indicates that the modulation mode is 16 orthogonal amplitude modulation (16- Quadrature Amplitude Modulation, called "16QAM", MCS with a coding rate of 1/2; network devices can then use this information on the PRB numbered 5~8, using the modulation method as 16QAM, and the coding rate is 1/ The MCS of 2 encodes and modulates the data transmitted to the UE, thereby generating a PDSCH, and can transmit it through the other 12 symbols of the UI. The UE may first receive the PDCCH on the first two symbols, acquire frequency information and MCS information, and receive the PDSCH according to the frequency information and the MCS information.
其中, Nc可以动态变化, 并且 UE可以通过盲检测来获取 Nc的值, 在 此以 Nc=2为例进行说明。 一个 PRB包括 12个子载波。对于上行传输而言, 网络设备可以在编号为 n的 ΤΉ向 UE发送 PDCCH, 其中承载上行动态调 度信令, 该上行动态调度信令包括频率信息和 MCS信息等; UE可以检测该 PDCCH, 并从中获取频率信息和 MCS信息等, 然后可以在编号为 n+4的 TTI上, 将数据根据 MCS信息进行编码和调制之后、 根据频率信息映射到 相应的 PRB上并发送出去。  The Nc can be dynamically changed, and the UE can obtain the value of Nc through blind detection. Here, Nc=2 is taken as an example for description. One PRB consists of 12 subcarriers. For the uplink transmission, the network device may send the PDCCH to the UE, where the number is n, and carry the uplink dynamic scheduling signaling, where the uplink dynamic scheduling signaling includes frequency information, MCS information, and the like; the UE may detect the PDCCH, and The frequency information, the MCS information, and the like are obtained, and then the data can be encoded and modulated according to the MCS information on the TTI numbered n+4, and then mapped to the corresponding PRB according to the frequency information and transmitted.
如果采用本发明实施例的方法, 即采用通过两个动态调度信令为用户设 备调度上行或下行资源的方法, 对于下行传输而言, 网络设备可以在编号为 n0(自然数)的 ΤΉ的前 Ncl个符号上,向 UE发送 PDCCH,其中该 PDCCH 包括频率信息和索引信息, 并可以根据该索引信息确定信息位; 网络设备可 以在编号为 nl ( nl>n0 ) 的 ΤΉ的前 Nc2个符号上再次发送 PDCCH, 其中 在所确定的信息位中承载发送给该 UE的第二动态调度信令, 例如第二动态 调度信令包括 MCS信息; 然后网络设备可以在编号为 nl的 ΤΉ上除了前 Nc2个符号之外的其它符号上向 UE发送 PDSCH, 其中该 PDSCH是根据该 MCS信息被编码和调制、 并^^据该频率信息映射到相应频率而最终形成的。 对于上行传输而言, 网络设备可以在编号为 ηθ的 ΤΉ的前 Ncl个符号 上向 UE发送 PDCCH,其中该 PDCCH包括频率信息和索引信息,并可以根 据该索引信息确定信息位; 网络设备可以在编号为 n2 ( n2>n0 ) 的 ΤΉ的前 Nc2个符号上再次向 UE发送 PDCCH, 其中在所确定的信息位中可以承载 发送给该 UE的第二动态调度信令, 例如该第二动态调度信令包括 MCS信 息; 然后网络设备可以在编号为 n3 ( n3>n2 ) 的 ΤΉ上接收 UE发送的物理 上行共享信道(Physical Uplink Shared Channel, 筒称为 "PUSCH" ), 其中该 PUSCH是根据该 MCS信息被编码和调制、并根据该频率信息映射到相应频 率而最终形成的。 If the method of the embodiment of the present invention is used, the method for scheduling uplink or downlink resources for the user equipment by using two dynamic scheduling signaling is adopted. For the downlink transmission, the network device may be in the front Ncl of the number n0 (natural number). On the symbol, the PDCCH is sent to the UE, where the PDCCH includes frequency information and index information, and the information bit can be determined according to the index information; the network device can be again on the first Nc2 symbols of the frame number nl (nl>n0) Transmitting a PDCCH, where the second dynamic scheduling signaling sent to the UE is carried in the determined information bit, for example, the second dynamic scheduling signaling includes MCS information; then the network device may be on the 编号 number nl except for the first Nc2 The PDSCH is transmitted to the UE on other symbols than the symbol, wherein the PDSCH is finally encoded according to the MCS information being encoded and modulated, and mapped to the corresponding frequency according to the frequency information. For the uplink transmission, the network device may send the PDCCH to the UE on the first Ncl symbols of the number ηθ, where the PDCCH includes frequency information and index information, and may determine the information bit according to the index information; The PDCCH is sent to the UE again on the first Nc2 symbols of the frame numbered n2 (n2>n0), where the second dynamic scheduling signaling sent to the UE may be carried in the determined information bit, for example, the second dynamic scheduling The signaling includes the MCS information. The network device can receive the physical uplink shared channel (the physical uplink shared channel (PUSCH)) sent by the UE on the port numbered n3 (n3>n2), where the PUSCH is according to the The MCS information is encoded and modulated and ultimately formed based on the frequency information being mapped to the corresponding frequency.
因此, 本发明实施例的调度无线资源的方法, 通过采用两个动态调度信 令为用户设备调度上行或下行资源, 能够使得调度方案更好地适应信道环境 的变化, 从而能够提高信号传输的可靠性, 提高用户体验; 另一方面, 网络 设备在第一动态调度信令中还承载网络设备后续发送给 UE的第二动态调度 信令的索引信息, 从而便于网络设备动态地向被调度的 UE指示第二动态调 度信令所对应的信息位, 由此本发明实施例的方法还能够充分利用有限的信 息位来满足多个 UE的调度,以降低动态调度信令所需要的信息位资源开销, 因而能够提高资源利用率。  Therefore, the method for scheduling radio resources in the embodiment of the present invention can use the two dynamic scheduling signaling to schedule uplink or downlink resources for the user equipment, so that the scheduling scheme can better adapt to changes in the channel environment, thereby improving signal transmission reliability. On the other hand, the network device also carries the index information of the second dynamic scheduling signaling that the network device subsequently sends to the UE in the first dynamic scheduling signaling, so that the network device can dynamically move to the scheduled UE. The information bits corresponding to the second dynamic scheduling signaling are indicated, so that the method of the embodiment of the present invention can fully utilize the limited information bits to satisfy the scheduling of multiple UEs, so as to reduce the information bit resource overhead required for dynamic scheduling signaling. Therefore, resource utilization can be improved.
例如, 有 2个 UE接入到一个网络设备中, 这 2个 UE可能被同时调度 也可能只有一个 UE被调度; 如果不使用本发明, 则网络设备需要为这两个 UE接收第二动态信令分配不同的第二动态信令的信息位, 便于这两个 UE 在不同的信息位上去获取网络设备发送给各自的第二动态调度信令, 因此网 络设备需要在每个 ΤΉ都为这两个 UE预留两个信息位。 而如果使用了本发 明, 网络设备可以在第一动态调度信令中就承载了信息位对应的索引信息, UE可以根据该索引信息来确定第二动态调度信令的信息位, 这样就不需要 在每次调度中都为这两个 UE预留两个信息位, 而仅需要根据实际的调度情 况预留即可。 例如在某个 ΤΉ中, 网络设备调度了 UE1 , 则可以在第一动态 调度信令中向 UE1指示第一信息位;而在另一 TTI中,网络设备调度了 UE2, 也可以在第一动态调度信令中向 UE2指示第一信息位。 由此, 对于这两个 TTI来说, 只需要一个信息位即可满足对这两个 UE的调度, 这样就可以大 大降低了第二动态调度信令所需的开销,从而能够进一步增强本发明方案的 可实施性。 以本发明应用于调度更多 UE的场景为例进行说明 , 若有 100个 UE接 入到一个网络设备中, 网络设备在一个 TTI中最多能够调度 10个 UE, 则根 据本发明就不需为每个 UE分别预留 1个信息位(总共 100个 ), 而只需总 共预留 10个即可。 若在第一 ΤΉ中网络设备调度了 UE1~UE10, 则仅需在 发送给它们的第一动态调度信令中分别将编号为 1~10的信息位分配给这 10 个 UE, 即可向这 10个 UE分别发送第二动态调度信令; 若在第二 ΤΉ中网 络设备调度了 UE11~20,则仅需在发送给它们的第一动态调度信令中仍然将 编号为 1~10的信息位分配给这 10个 UE。 在这种情况下, 网络设备仅需 10 个信息位就满足了对 100个 UE的调度, 从而能够显著降低第二动态信令所 需的开销, 提高资源的利用率。 For example, if two UEs are connected to one network device, the two UEs may be scheduled simultaneously or only one UE may be scheduled; if the invention is not used, the network device needs to receive the second dynamic message for the two UEs. The information bits of the second dynamic signaling are allocated differently, so that the two UEs acquire the second dynamic scheduling signaling sent by the network device to the respective information bits on different information bits, so the network device needs to be the two in each of the two. The UE reserves two information bits. If the present invention is used, the network device may carry the index information corresponding to the information bit in the first dynamic scheduling signaling, and the UE may determine the information bit of the second dynamic scheduling signaling according to the index information, so that the network device does not need to In each scheduling, two information bits are reserved for the two UEs, and only need to be reserved according to the actual scheduling situation. For example, in a certain network, if the network device schedules the UE1, the first information bit may be indicated to the UE1 in the first dynamic scheduling signaling; and in another TTI, the network device schedules the UE2, and may also be in the first dynamic. The first information bit is indicated to the UE2 in the scheduling signaling. Therefore, for the two TTIs, only one information bit is needed to satisfy the scheduling of the two UEs, so that the overhead required for the second dynamic scheduling signaling can be greatly reduced, thereby further enhancing the present invention. The feasibility of the program. The scenario in which the present invention is applied to scheduling more UEs is taken as an example. If 100 UEs are connected to one network device, and the network device can schedule up to 10 UEs in one TTI, the present invention does not need to be Each UE reserves one information bit (100 in total), and only a total of 10 are reserved. If the network device schedules the UE1 to the UE10 in the first network, the information bits numbered 1 to 10 are respectively allocated to the 10 UEs in the first dynamic scheduling signaling sent to them. The 10 UEs respectively send the second dynamic scheduling signaling. If the network device schedules the UEs 11 to 20 in the second network, the information that is numbered 1 to 10 is still only needed in the first dynamic scheduling signaling sent to them. Bits are allocated to these 10 UEs. In this case, the network device only needs 10 information bits to satisfy the scheduling of 100 UEs, thereby significantly reducing the overhead required for the second dynamic signaling and improving resource utilization.
应理解, 调制和编码是两种控制数据传输速率的方法, 通常调制阶数越 高, 或者编码速率越高, 相同资源能承载的信息比特数就越多, 对无线信道 的要求就越高。 在信号传输方案中, 通常可以采用自适应调制、 自适应编码 或自适应调制编码方法,从而可以根据信道质量的好坏来调整传输速率的高 低, 由此可以在保证可靠传输的前提下提升传输效率。 虽然本说明书仅以自 适应调制编码为例进行说明, 但可以理解, 本发明并不限于此, 本发明也可 以采用自适应调制、 自适应编码或其它方法。  It should be understood that modulation and coding are two methods for controlling the data transmission rate. Generally, the higher the modulation order, or the higher the coding rate, the more information bits that the same resource can carry, and the higher the requirement for the wireless channel. In the signal transmission scheme, adaptive modulation, adaptive coding or adaptive modulation and coding methods can usually be adopted, so that the transmission rate can be adjusted according to the quality of the channel, thereby improving transmission under the premise of ensuring reliable transmission. effectiveness. Although the present specification has been described by taking adaptive modulation coding as an example, it can be understood that the present invention is not limited thereto, and the present invention may also employ adaptive modulation, adaptive coding or other methods.
还应理解, 在本发明实施例中, 网络设备可以根据信道的变化来确定用 户设备的第二动态调度信令, 或者网络设备也可以在两次动态调度信令中间 获取干扰的变化情况, 由此来确定用户设备的第二动态调度信令的内容, 网 络设备还可以根据其它方法来确定用户设备的第二动态调度信令的方法,本 发明实施例并不限于此。  It should also be understood that, in the embodiment of the present invention, the network device may determine the second dynamic scheduling signaling of the user equipment according to the change of the channel, or the network device may also obtain the interference change in the middle of the two dynamic scheduling signaling, The method for determining the content of the second dynamic scheduling signaling of the user equipment, and the method for determining the second dynamic scheduling signaling of the user equipment according to other methods, the embodiment of the present invention is not limited thereto.
例如, 网络设备可以在发送第一动态调度信令之后发送参考信号 ( Reference Signal, 筒称为 "RS" ), UE收到该 RS之后可以测量该 RS, 并 将测量结果报告给网络设备, 网络设备可以再根据所获取的测量结果报告, 确定第二动态调度信令的内容, 并发送给 UE以便于 UE确定下行调度; 或 者, 例如网络设备可以在发送第一动态调度信令之后, 接收 UE发送的 RS 并测量该 RS, 并可以根据测量结果来确定第二动态调度信令的内容, 从而 网络设备可以将该第二动态调度信令发送给 UE, 以便于 UE确定上行调度。  For example, the network device may send a reference signal (referred to as "RS") after transmitting the first dynamic scheduling signaling, and the UE may measure the RS after receiving the RS, and report the measurement result to the network device, the network. The device may further determine the content of the second dynamic scheduling signaling according to the obtained measurement result report, and send the content to the UE for the UE to determine the downlink scheduling. Alternatively, for example, the network device may receive the UE after sending the first dynamic scheduling signaling. The RS is sent and the RS is measured, and the content of the second dynamic scheduling signaling is determined according to the measurement result, so that the network device can send the second dynamic scheduling signaling to the UE, so that the UE determines the uplink scheduling.
还应理解, 在本发明实施例中, "动态" 表示不同 ΤΉ的相应配置和信 令都可以不同。 还应理解, 在本发明实施例中, 网络设备可以为基站 BS、 接入点 AP、 远端无线设备 RRE、 远端无线端口 RRH、 远端无线单元 RRU 或中继节点 RN等; 在本发明实施例中, 网络设备与小区的关系也不限, 例 如一个网络设备可以对应一个或多个小区, 或者一个小区可以对应一个或多 个网络设备。 It should also be understood that in the embodiments of the present invention, "dynamic" means that different configurations and signaling of different ports may be different. It should also be understood that, in the embodiment of the present invention, the network device may be a base station BS, The access point AP, the remote radio device RRE, the remote radio port RRH, the remote radio unit RRU or the relay node RN, etc.; in the embodiment of the present invention, the relationship between the network device and the cell is not limited, for example, a network device One or more cells may be corresponding, or one cell may correspond to one or more network devices.
在本发明实施例中, 可选地, 该第一用户设备的第二动态调度信令包括 下列信息中的至少一种: 调制方式、 编码速率、 发送天线端口和预编码矩阵 指示 ( Precoding Matrix Indicator, 筒称为 "ΡΜΓ )。  In the embodiment of the present invention, optionally, the second dynamic scheduling signaling of the first user equipment includes at least one of the following information: a modulation mode, a coding rate, a transmit antenna port, and a precoding matrix indicator (Precoding Matrix Indicator) , the tube is called "ΡΜΓ".
上文中已经给出了 MCS的例子, 即第二动态调度信令包括调制方式和 编码速率的实施例, 第二动态调度信令也可以仅包括调制方式或编码速率, 为了筒洁, 在此不再赘述。  An example of the MCS has been given above, that is, the second dynamic scheduling signaling includes an embodiment of a modulation mode and a coding rate, and the second dynamic scheduling signaling may also include only a modulation mode or a coding rate. Let me repeat.
在现有技术中, 以上行传输为例, 当 UE能够从多个天线端口中的任何 一个天线端口发送上行信号时, 网络设备可以根据这些天线端口对应的信道 情况,动态地选择其中的一个天线端口来发送上行信号。在本发明实施例中, 网络设备可以根据信道环境的变化再次确定更为合适的天线端口, 并将天线 端口的信息置于第二动态调度信令中发送给 UE, 由此 UE可以根据信道环 境的变化来发送 PUSCH。  In the prior art, the uplink transmission is taken as an example. When the UE can send an uplink signal from any one of the multiple antenna ports, the network device can dynamically select one of the antennas according to the channel condition corresponding to the antenna ports. The port sends an upstream signal. In the embodiment of the present invention, the network device may determine a more suitable antenna port according to the change of the channel environment, and send the information of the antenna port to the UE in the second dynamic scheduling signaling, so that the UE may be according to the channel environment. The change to send the PUSCH.
类似地, 对于 PMI而言, 在现有技术中, 以上行传输为例, 当 UE能够 从多个天线端口中的任何一个天线端口发送上行信号时, 网络设备可以根据 这些天线端口对应的信道情况,动态地在候选的若干 PMI中选择其中的一个 PMI来发送上行信号。 在本发明实施例中, PMI信息可以被置于第二动态调 度信令中发送给 UE, 这样网络设备可以根据信道环境的变化确定更为合适 的 PMI来使得 UE发送 PUSCH, 从而能够提高信号传输的可靠性, 提高用 户体验。  Similarly, for the PMI, in the prior art, the uplink transmission is taken as an example. When the UE can send an uplink signal from any one of the multiple antenna ports, the network device can determine the channel condition corresponding to the antenna ports. One of the candidate PMIs is dynamically selected to transmit an uplink signal. In the embodiment of the present invention, the PMI information may be sent to the UE in the second dynamic scheduling signaling, so that the network device may determine a more suitable PMI according to the change of the channel environment, so that the UE sends the PUSCH, thereby improving signal transmission. Reliability, improve the user experience.

例如, 在下行传输中, 第二时段与网络设备根据该第二动态调度信令向 UE发送下行数据信号的第三时段可以属于相同的 ΤΉ, 即对于下行传输而 言, 网络设备向 UE发送第二动态调度信令之后, 可以在当前 ΤΉ内立即向 UE发送下行数据信号, 从而能够降低时延, 提高用户体验。 例如, 在上行 传输中, 网络设备向 UE发送第二动态调度信令之后, 为了给 UE预留一定 时间来解码用于上行传输的该第二动态调度信令, 网络设备可以在下一 ΤΤΙ 接收 UE发送的上行数据信号。  For example, in the downlink transmission, the second period of time that the network device sends the downlink data signal to the UE according to the second dynamic scheduling signaling may belong to the same ΤΉ, that is, for the downlink transmission, the network device sends the After the dynamic scheduling signaling, the downlink data signal can be immediately sent to the UE in the current frame, thereby reducing the delay and improving the user experience. For example, in the uplink transmission, after the network device sends the second dynamic scheduling signaling to the UE, in order to reserve a certain time for the UE to decode the second dynamic scheduling signaling for the uplink transmission, the network device may receive the UE in the next ΤΤΙ. The uplink data signal sent.
应理解, 在本发明实施例中, 网络设备确定信息位的时刻与第一时刻或 第二时刻可以属于相同的 ΤΉ, 也可以属于不同的 ΤΉ, 本发明实施例并不 限于此。 It should be understood that, in the embodiment of the present invention, the time when the network device determines the information bit may be the same as the first time or the second time, or may belong to different parameters, and the embodiment of the present invention does not Limited to this.
还应理解, 通常在一个通信系统中, 会将时间维度以某一长度为单位进 行划分。 例如在 LTE系统中, 以 ΤΉ为单位对时间维度进行划分, 1个 TTI 的时间长度为 lms。 并且由于传输的时延, 网络设备与用户设备会对同样的 绝对时间进行不同的划分, 例如网络设备发送某个 ΤΉ, UE会延迟收到, 因此两者理解的 ΤΉ不同。本发明所述的时刻表示某项操作所处于的时间段 的编号, 例如可以为 ΤΉ的编号。  It should also be understood that the time dimension is typically divided by a certain length in a communication system. For example, in an LTE system, the time dimension is divided in units of ,, and the length of one TTI is lms. And because of the delay of the transmission, the network device and the user equipment will divide the same absolute time differently. For example, if the network device sends a certain ΤΉ, the UE will delay the reception, so the two understand different ΤΉ. The time instant described in the present invention indicates the number of the time period in which an operation is located, and may be, for example, a number of ΤΉ.
在本发明实施例中, 可选地, 该第一用户设备的第二动态调度信令包括 功率控制信息, 在图 1的 S130中, 该接收该第一用户设备根据该第一用户 设备的第二动态调度信令发送的上行数据信号, 包括:  In the embodiment of the present invention, optionally, the second dynamic scheduling signaling of the first user equipment includes power control information, and in S130 of FIG. 1, the receiving the first user equipment is according to the first user equipment. The uplink data signal sent by the dynamic scheduling signaling includes:
接收该第一用户设备根据该第一用户设备的第二动态调度信令包括的 该功率控制信息发送的上行数据信号。  Receiving, by the first user equipment, an uplink data signal that is sent according to the power control information included in the second dynamic scheduling signaling of the first user equipment.
具体而言, 在现有技术中, 网络设备可以在 PDCCH中包括功率控制信 息, 用于控制 UE发送 PUSCH时所使用的发送功率。 而在本发明实施例中, 可以将功率控制信息置于第二动态调度信令中发送, 这样可以根据信道环境 的变化调整 UE发送 PUSCH时使用的发送功率, 由此可以进一步使得调度 方案更好地适应信道环境的变化, 从而能够进一步提高信号传输的可靠性, 提高用户体验。  Specifically, in the prior art, the network device may include power control information in the PDCCH for controlling the transmission power used by the UE when transmitting the PUSCH. In the embodiment of the present invention, the power control information may be sent in the second dynamic scheduling signaling, so that the transmit power used by the UE to transmit the PUSCH may be adjusted according to the change of the channel environment, thereby further making the scheduling scheme better. The ground adapts to changes in the channel environment, thereby further improving the reliability of signal transmission and improving the user experience.
另外, 应理解, 在无线通信系统中, 下行发送功率通常不会动态变化, 而在上行传输中, 由于 UE的移动性等原因, 功率控制信息通常可以动态调 节, 因此可以仅在上行调度过程中调整功率控制信息。  In addition, it should be understood that in the wireless communication system, the downlink transmission power does not normally change dynamically, but in the uplink transmission, the power control information can be dynamically adjusted due to the mobility of the UE, etc., and thus can be only in the uplink scheduling process. Adjust power control information.
在本发明实施例中, 可选地, 在图 1的 S120中, 该在该索引信息指示 的该信息位上向该第一用户设备发送该第一用户设备的第二动态调度信令, 包括:  In the embodiment of the present invention, optionally, in S120 of FIG. 1, the second dynamic scheduling signaling of the first user equipment is sent to the first user equipment by using the information bit indicated by the index information, including :
以组播或多播的方式向该第一用户设备发送以组标识符进行标识的信 令包, 该信令包包括该第一用户设备的第二动态调度信令, 以及包括除该第 一用户设备之外的至少一个用户设备的第二用户设备的第二动态调度信令, 该信息位指示该第一用户设备的第二动态调度信令在该信令包中的位置。  Transmitting, by multicast or multicast, a signaling packet identified by a group identifier to the first user equipment, where the signaling packet includes second dynamic scheduling signaling of the first user equipment, and includes the first A second dynamic scheduling signaling of the second user equipment of the at least one user equipment other than the user equipment, the information bit indicating a location of the second dynamic scheduling signaling of the first user equipment in the signaling packet.
具体而言, 在本发明实施例中, 网络设备可以将多个 UE的第二动态调 度信令组合为一个信令包, 并发送给多个 UE, 其中信令包使用组标识符进 行标识, 并且每个用户设备的第二动态调度信令在该信令包中的位置, 与网 络设备根据索引信息确定的用于承载该用户设备的第二动态调度信令的信 息位相应。 例如, 网络设备向第一用户设备发送的第一动态调度信令中的索 引信息所指示的信息位, 用于指示该第一用户设备的第二动态调度信令在该 信令包中的位置。 Specifically, in the embodiment of the present invention, the network device may combine the second dynamic scheduling signaling of multiple UEs into one signaling packet, and send the signaling packet to multiple UEs, where the signaling packet is identified by using the group identifier. And the location of the second dynamic scheduling signaling of each user equipment in the signaling packet, and the network The information bits of the second dynamic scheduling signaling used by the network device to carry the user equipment according to the index information are corresponding. For example, the information bit indicated by the index information in the first dynamic scheduling signaling sent by the network device to the first user equipment is used to indicate the location of the second dynamic scheduling signaling of the first user equipment in the signaling packet. .
例如, 假设每个 UE对应的第二动态调度信令包括 2比特, 一个信令包 可以包括发送给 20个 UE的信令, 则一个信令包的信息量包括 40比特。 网 络设备对这 40比特进行编码、 调制之后, 可以使用组标识符进行标识, 最 后映射到 PDCCH资源上以组播或多播的方式发送出去。 所有检测到第一动 态调度信令的 UE就可以使用组标识符去检测信令包, 并可以根据在第一动 态调度信令中获取的索引信息,确定与网络设备发送给自己的第二动态调度 信令相应的信息位,从而该用户设备可以从信令包中获取自己的第二动态调 度信令, 即 2比特信息, 由此该用户设备可以根据该第二动态调度信令调整 调度方案, 以提高信号传输的可靠性, 并提高用户体验。  For example, it is assumed that the second dynamic scheduling signaling corresponding to each UE includes 2 bits, and one signaling packet may include signaling sent to 20 UEs, and the information amount of one signaling packet includes 40 bits. After the network device encodes and modulates the 40 bits, it can be identified by using the group identifier, and finally mapped to the PDCCH resource and sent by multicast or multicast. All UEs that detect the first dynamic scheduling signaling may use the group identifier to detect the signaling packet, and may determine the second dynamic sent to the network device according to the index information obtained in the first dynamic scheduling signaling. Scheduling signaling corresponding information bits, so that the user equipment can obtain its own second dynamic scheduling signaling, that is, 2-bit information, from the signaling packet, so that the user equipment can adjust the scheduling scheme according to the second dynamic scheduling signaling. To improve the reliability of signal transmission and improve the user experience.
另一方面, 网络设备利用这种组播或多播的方法, 可以将多个 UE的第 二动态调度信令组合成为一个信令包再统一进行发送, 能够降低网络设备的 复杂度; 并且多个 UE也可以仅检测被一个标识符标识的信令包, 能够降低 网络设备向 UE通知标识符的信令以及 UE实现的复杂度。  On the other hand, the network device can use the multicast or multicast method to combine the second dynamic scheduling signaling of multiple UEs into one signaling packet and then uniformly transmit the information, which can reduce the complexity of the network device; The UEs may also detect only the signaling packets identified by one identifier, and can reduce the signaling that the network device notifies the UE of the identifier and the complexity of the UE implementation.
在本发明实施例中, 可选地, 该第一用户设备和该第二用户设备被调度 的传输时间间隔的编号相同, 即该信令包包括的各第二动态调度信令所属的 各用户设备被调度的传输时间间隔的编号相同。  In the embodiment of the present invention, optionally, the first user equipment and the second user equipment are scheduled to have the same transmission time interval, that is, each user to which the second dynamic scheduling signaling included in the signaling packet belongs. The number of transmission intervals scheduled by the device is the same.
具体而言, 例如, 对于特定小区而言, 在特定 ΤΉ被调度的所有 UE可 以使用相同的标识符, 从而网络设备就可以只需发送一个信令包, 即可向所 有在该 TTI 中被调度的 UE发送第二动态调度信令, 无需考虑将被调度的 UE分为至少一个组的复杂设计, 并且被调度的 UE也仅需要检测一个信令 包即可。 因此,根据本发明实施例的方法, 还可以筒化调度,提高调度效率, 增强用户体验。  Specifically, for example, for a specific cell, all UEs scheduled at a specific frame can use the same identifier, so that the network device can send only one signaling packet, and can be scheduled to all in the TTI. The UE sends the second dynamic scheduling signaling without considering the complicated design of dividing the scheduled UE into at least one group, and the scheduled UE only needs to detect one signaling packet. Therefore, according to the method of the embodiment of the present invention, scheduling can also be implemented, the scheduling efficiency is improved, and the user experience is enhanced.
应理解, 在本发明实施例中, 网络设备和小区的关系不限, 一个网络设 备可以包括一个或多个小区, 或者一个小区可以包括一个或多个网络设备, 即多个网络设备使用相同的小区 ID。  It should be understood that, in the embodiment of the present invention, the relationship between the network device and the cell is not limited, one network device may include one or more cells, or one cell may include one or more network devices, that is, multiple network devices use the same Cell ID.
在本发明实施例中, 可选地, 该组标识符的值根据该第一用户设备所属 的小区的标识确定。 即网络设备可以根据第一用户设备所属的小区的标识确 定组标识符的值, 并可以以组播或多播的方式向该第一用户设备发送以该组 标识符进行标识的信令包。 In the embodiment of the present invention, optionally, the value of the group identifier is determined according to the identifier of the cell to which the first user equipment belongs. That is, the network device can be determined according to the identity of the cell to which the first user equipment belongs. The value of the group identifier is set, and the signaling packet identified by the group identifier may be sent to the first user equipment in a multicast or multicast manner.
应理解, 组标识符的值可以是第一用户设备所属的小区的标识的函数, 或组标识符的值可以与第一用户设备所属的小区的标识具有映射关系等, 只 要该组标识符的值与第一用户设备所属的小区的标识相关即可; 优选地, 不 同小区使用不同的组标识符, 来标识包括第二动态调度信令的信令包, 但本 发明实施例并不限于此。  It should be understood that the value of the group identifier may be a function of the identifier of the cell to which the first user equipment belongs, or the value of the group identifier may have a mapping relationship with the identifier of the cell to which the first user equipment belongs, as long as the group identifier The value may be related to the identifier of the cell to which the first user equipment belongs; preferably, different cells use different group identifiers to identify the signaling packet including the second dynamic scheduling signaling, but the embodiment of the present invention is not limited thereto. .
例如, 该第一用户设备的第二动态调度信令的组标识符的值为该第一用 户设备所属的小区的标识, 如下面的等式(1 )所示:  For example, the value of the group identifier of the second dynamic scheduling signaling of the first user equipment is the identifier of the cell to which the first user equipment belongs, as shown in the following equation (1):
A = NceUID ( 1 ) 其中, A表示组标识符的值, Λ^Βίβ表示该第一用户设备所属的小区的 ID。 由于包括第二动态调度信令的信令包的组标识符的值根据用户设备所 属的小区的标识确定, 因而不同小区可以使用不同的标识符来标识第二动态 调度信令, 从而并未接入该小区的 UE就无法获取第二动态调度信令, 由此 能够实现加密; 并且不同小区由于其小区 ID不同, 就使用不同的标识符, 能够降低 UE检测第二动态调度信令错误率。 A = N ceUID ( 1 ) where A represents the value of the group identifier, and Λ^ Βίβ represents the ID of the cell to which the first user equipment belongs. Since the value of the group identifier of the signaling packet including the second dynamic scheduling signaling is determined according to the identifier of the cell to which the user equipment belongs, different cells may use different identifiers to identify the second dynamic scheduling signaling, thereby not receiving The UE entering the cell cannot obtain the second dynamic scheduling signaling, thereby enabling encryption; and different cells use different identifiers because their cell IDs are different, which can reduce the UE detecting the second dynamic scheduling signaling error rate.
在本发明实施例中, 可选地, 该组标识符的值根据该第一用户设备被调 度时的传输时间间隔的编号确定。 即用户设备被调度时的传输时间间隔 TTI 的编号不同时, 包括该用户设备的第二动态调度信令的信令包的组标识符的 值不同。  In the embodiment of the present invention, optionally, the value of the group identifier is determined according to the number of the transmission time interval when the first user equipment is scheduled. That is, when the number of transmission time intervals TTI when the user equipment is scheduled is different, the value of the group identifier of the signaling packet including the second dynamic scheduling signaling of the user equipment is different.
具体而言, 第二动态调度信令的标识符在不同的 ΤΉ可以为不同值, 也 即标识符在时间上发生跳变, 例如, 第一用户设备的第二动态调度信令的组 标识符的值可以如下面的等式(2 )所示:  Specifically, the identifiers of the second dynamic scheduling signaling may be different values at different ports, that is, the identifiers are hopped in time, for example, the group identifier of the second dynamic scheduling signaling of the first user equipment. The value can be as shown in equation (2) below:
A = (NcellID + n7TI ) modNA ( 2 ) 其中, A表示组标识符的值, Λ^Βίβ表示该第一用户设备所属的小区的 ID,A = (N cellID + n 7TI ) modN A ( 2 ) where A represents the value of the group identifier, and Λ^ Βίβ represents the ID of the cell to which the first user equipment belongs,
«m表示 ΤΉ的编号, ^用于控制标识符的取值范围为 [0 ~ NA - 1 ] , mod表 示取模操作。 « m indicates the number of ΤΉ, ^ is used to control the value range of the identifier [0 ~ N A - 1 ], and mod represents the modulo operation.
例如, 第一用户设备的第二动态调度信令的组标识符的值也可以如下面 的等式(3 )所示:  For example, the value of the group identifier of the second dynamic scheduling signaling of the first user equipment may also be as shown in the following equation (3):
A = (NceUID + c(wm )) mod NA ( 3 ) 其中, c(«m)为一个随机序列, 其取值随着 /^的变化而变化。 因此, 在本发明实施例中, 不同小区的随机序列不同, 从而能达到更好 的加密效果。 A = (N ceUID + c(w m )) mod N A ( 3 ) where c(« m ) is a random sequence whose value varies with /^. Therefore, in the embodiment of the present invention, the random sequences of different cells are different, so that a better encryption effect can be achieved.
在本发明实施例中, 可选地, 该信令包的大小为固定值; 或该信令包的 大小为网络设备通过广播通知的第一值; 或该信令包的大小根据系统带宽、 动态调度信令的资源容量和该索引信息的比特数目中的至少一种信息确定。  In the embodiment of the present invention, optionally, the size of the signaling packet is a fixed value; or the size of the signaling packet is a first value notified by the network device by using a broadcast; or the size of the signaling packet is based on a system bandwidth, At least one of the resource capacity of the dynamic scheduling signaling and the number of bits of the index information is determined.
即, 在本发明实施例中, 对于网络设备以组播或多播的方式向该用户设 备发送的以组标识符进行标识的信令包, 该信令包的大小信令包的大小可以 是固定值; 或者由网络设备提前向 UE广播通知; 或者取决于系统带宽、 动 态调度信令的资源容量和该索引信息的比特数目中的至少一种信息,但本发 明实施例并不限于此。  That is, in the embodiment of the present invention, for the signaling packet that is sent by the network device to the user equipment by using the group identifier in a multicast or multicast manner, the size of the signaling packet of the signaling packet may be The fixed value; or the network device broadcasts the notification to the UE in advance; or depends on at least one of the system bandwidth, the resource capacity of the dynamic scheduling signaling, and the number of bits of the index information, but the embodiment of the present invention is not limited thereto.
具体而言, 信令包的大小可以是固定值, 例如信令包的大小为 40个比 特。 例如信令包的大小可以取决于系统带宽, 例如系统带宽为 10MHz时信 令包的大小可以为 40比特, 系统带宽为 20MHz时信令包的大小可以为 80 比特等等, 通常系统带宽越大, 网络设备可以在一个 ΤΉ中调度的 UE数就 越多, 所需的信令开销也就越大。  Specifically, the size of the signaling packet may be a fixed value, for example, the size of the signaling packet is 40 bits. For example, the size of the signaling packet may depend on the system bandwidth. For example, when the system bandwidth is 10 MHz, the size of the signaling packet may be 40 bits, and when the system bandwidth is 20 MHz, the size of the signaling packet may be 80 bits, etc., generally, the system bandwidth is larger. The more UEs a network device can schedule in a network, the greater the signaling overhead required.
例如,信令包的大小可以取决于动态调度信令的容量。例如在 LTE系统 中, 对于系统带宽为 10MHz ( 600个子载波)的情况, 网络设备最多可以使 用 3个 OFDM符号来传输 PDCCH, 因此一个 ΤΉ中可用于传输 PDCCH的 RE (即时间上的一个符号和频率上的一个子载波)总数可以为 =1800; 而每 个 PDCCH只能通过 1、 2、 4或 8个控制信道单元( Control Channel Element, 筒称为 "CCE" )被传输, 每个 CCE包括 36个 RE, 这样一个 ΤΉ最多就能 传输 1800/36=50个 CCE, 即最多传输 50个 PDCCH。 因此, 信令包也最多 包括 50个 UE的第二动态调度信令, 即信令包的大小最大可以为 100个比 特。 这样的设计能够匹配 PDCCH资源容量, 更为合理。  For example, the size of the signaling packet may depend on the capacity of the dynamic scheduling signaling. For example, in the LTE system, for a case where the system bandwidth is 10 MHz (600 subcarriers), the network device can use up to 3 OFDM symbols to transmit the PDCCH, so one RE can be used to transmit the RE of the PDCCH (ie, a symbol sum in time) The total number of subcarriers on the frequency can be =1800; and each PDCCH can only be transmitted through 1, 2, 4 or 8 control channel elements (Control Channel Element, called "CCE"), each CCE includes 36 REs, such a ΤΉ can transmit up to 1800/36=50 CCEs, that is, a maximum of 50 PDCCHs are transmitted. Therefore, the signaling packet also includes a maximum of 50 UEs' second dynamic scheduling signaling, that is, the signaling packet size may be up to 100 bits. Such a design can match the PDCCH resource capacity, which is more reasonable.
或者在本发明实施例中, 网络设备可以提前向 UE发送广播信令来通知 信令包的大小, 从而网络设备可以根据业务量的变化适时调整信令包大小。 例如, 当业务量较为繁忙时, 网络设备可以向 UE发送广播信令通知信令包 的大小为 80个比特, 这样网络设备就可以调度最多 40个 UE; 当业务量不 繁忙时, 网络设备可以向 UE发送广播信令通知信令包的大小为 40个比特, 这样网络设备就可以降低信令包的开销。  Or in the embodiment of the present invention, the network device may send broadcast signaling to the UE in advance to notify the size of the signaling packet, so that the network device can adjust the signaling packet size according to the change of the traffic volume. For example, when the traffic is relatively busy, the network device can send a broadcast signaling notification packet to the UE with a size of 80 bits, so that the network device can schedule up to 40 UEs; when the traffic is not busy, the network device can The size of the broadcast signaling notification signaling packet sent to the UE is 40 bits, so that the network device can reduce the overhead of the signaling packet.
在本发明实施例中, 网络设备通知 UE的方法不限, 网络设备也可以不 直接通知信令包所包括的比特数目, 而是向 UE通知一个系数; 例如, 网络 设备向 UE通知系数为 (每个单位对应 40个比特 ), 则信令包的大小就是 80个比特; 如果向 UE通知系数为 0.5, 则信令包的大小就是 20个比特。 在 本发明实施例中,网络设备通过广播信令通知信令包的大小,能够降低开销, 即不需要向每个 UE都发送 UE专用的信令来通知。 In the embodiment of the present invention, the method for the network device to notify the UE is not limited, and the network device may not Directly notifying the number of bits included in the signaling packet, but notifying the UE of a coefficient; for example, if the network device notifies the UE that the coefficient is (each unit corresponds to 40 bits), the size of the signaling packet is 80 bits; The UE is notified that the coefficient is 0.5, and the size of the signaling packet is 20 bits. In the embodiment of the present invention, the network device notifies the size of the signaling packet by using the broadcast signaling, and the overhead can be reduced, that is, the UE-specific signaling is not required to be notified to each UE.
在本发明实施例中,信令包的大小还可以取决于第一动态调度信令中承 载索引信息的比特数目, 该索引比特的比特数目可以是固定值、 或者取决于 系统带宽、 或者取决于动态调度信令的资源容量、 或者由网络设备提前向 UE广播来通知。 因此, 在本发明实施例中, 可选地, 该索引信息的比特数 目为固定值; 或该索引信息的比特数目为该网络设备通过广播通知的第二 值; 或该索引信息的比特数目根据系统带宽和动态调度信令的资源容量中的 至少一种信息确定。  In the embodiment of the present invention, the size of the signaling packet may also depend on the number of bits carrying the index information in the first dynamic scheduling signaling, and the number of bits of the index bit may be a fixed value, or depends on system bandwidth, or The resource capacity of the dynamic scheduling signaling, or broadcasted by the network device to the UE in advance to notify. Therefore, in the embodiment of the present invention, optionally, the number of bits of the index information is a fixed value; or the number of bits of the index information is a second value notified by the network device by broadcast; or the number of bits of the index information is according to At least one of system bandwidth and resource capacity of dynamic scheduling signaling is determined.
例如, 第一动态调度信令中的索引信息的比特数目为 5 , 则就能传递 25=32个不同的索引信息,对应能够支持同时向最多 32个 UE发送第二动态 调度信令, 因此, 若每个第二动态调度信令包括 2比特, 则承载第二动态调 度信令的信令包的大小就可以为 64个比特。 For example, if the number of bits of the index information in the first dynamic scheduling signaling is 5, then 2 5 = 32 different index information can be transmitted, and the corresponding dynamic packet signaling can be simultaneously sent to a maximum of 32 UEs. If the second dynamic scheduling signaling includes 2 bits, the size of the signaling packet carrying the second dynamic scheduling signaling may be 64 bits.
在本发明实施例中, 可选地, 该信令包包括的该第一用户设备和该第二 用户设备的第二动态调度信令的长度相同。 即该信令包包括的各用户设备的 第二动态调度信令的长度相同。 可选地, 该第一用户设备的第二动态调度信 令的长度为预存值; 或该第一用户设备的第二动态调度信令的长度为网络设 备通过广播通知的第三值。  In the embodiment of the present invention, optionally, the first user equipment included in the signaling packet and the second dynamic scheduling signaling of the second user equipment are the same length. That is, the second dynamic scheduling signaling of each user equipment included in the signaling packet has the same length. Optionally, the length of the second dynamic scheduling signaling of the first user equipment is a pre-stored value; or the length of the second dynamic scheduling signaling of the first user equipment is a third value that is notified by the network device by broadcast.
具体而言, 该信令包包括多个用户设备的第二动态调度信令, 每个用户 设备的动态调度信令的长度可以相同, 该长度例如为固定值或预存值, 或者 该长度可以由网络设备提前以广播的形式通知各个用户设备,但本发明实施 例并不限于此, 例如, 每个 UE的动态调度信令的长度也可以不相同。  Specifically, the signaling packet includes the second dynamic scheduling signaling of the multiple user equipments, and the length of the dynamic scheduling signaling of each user equipment may be the same, the length is, for example, a fixed value or a pre-stored value, or the length may be The network device notifies the user equipment in advance in the form of a broadcast, but the embodiment of the present invention is not limited thereto. For example, the length of the dynamic scheduling signaling of each UE may also be different.
上面的实施例都假设第二动态调度信令包括 2个比特,这是每个第二动 态调度信令包括的比特数目为固定值的实施例, 可选地, 第二动态调度信令 包括的比特数也可以由网络设备向 UE发送信令来通知, 例如网络设备通知 为 3, 则每个第二动态调度信令包括 3比特。  The above embodiment assumes that the second dynamic scheduling signaling includes 2 bits, which is an embodiment in which the number of bits included in each second dynamic scheduling signaling is a fixed value, optionally, the second dynamic scheduling signaling includes The number of bits may also be signaled by the network device to the UE to notify, for example, that the network device notification is 3, and each second dynamic scheduling signaling includes 3 bits.
若每个 UE的第二动态调度信令包括 Nb个比特,包括多个 UE的第二动 态调度信令组成的信令包总共包括 Nb x Ns个比特, 其中 Ns表示一个信令组 中包括的第二动态调度信令的数目; UE根据第一动态调度信令中的索引信 息确定信息位的具体过程可以是: 若 UE在第一动态调度信令中收到索引信 息为 则 UE确定编号为 Nb X i , Nb x n! +1 , · · · , Nb x ( i^ +U -l的 Nb 个比特为网络设备向自己发送的第二动态调度信令。 If the second dynamic scheduling signaling of each UE includes N b bits, the signaling packet consisting of the second dynamic scheduling signaling of the multiple UEs includes a total of N b x N s bits, where N s represents one signaling Group The number of the second dynamic scheduling signaling included in the UE; the specific process of determining the information bit by the UE according to the index information in the first dynamic scheduling signaling may be: if the UE receives the index information in the first dynamic scheduling signaling, then the UE The N b bits numbered Nb X i , N b xn ! +1 , · · · , N b x ( i^ + U -l are determined as the second dynamic scheduling signaling sent by the network device to itself.
因此, 本发明实施例的调度无线资源的方法, 通过采用两个动态调度信 令为用户设备调度上行或下行资源, 能够使得调度方案更好地适应信道环境 的变化, 从而能够提高信号传输的可靠性, 提高用户体验。  Therefore, the method for scheduling radio resources in the embodiment of the present invention can use the two dynamic scheduling signaling to schedule uplink or downlink resources for the user equipment, so that the scheduling scheme can better adapt to changes in the channel environment, thereby improving signal transmission reliability. Sex, improve the user experience.
在本发明实施例中, 可选地, 如图 2所示, 在向该第一用户设备发送下 行数据信号或接收该第一用户设备发送的上行数据信号之前, 该方法 100还 包括:  In the embodiment of the present invention, optionally, as shown in FIG. 2, before the sending the downlink data signal to the first user equipment or receiving the uplink data signal sent by the first user equipment, the method 100 further includes:
S 140 ,向该第一用户设备发送该第一用户设备的第二动态调度信令的长 度, 该第一用户设备的第二动态调度信令的长度与该第二用户设备中的至少 一个用户设备的第二动态调度信令的长度不同, 该第一用户设备的第二动态 调度信令的长度用于使得该第一用户设备根据该长度,确定承载该第一用户 设备的第二动态调度信令的信息位。  S140. The length of the second dynamic scheduling signaling of the first user equipment is sent to the first user equipment, where the length of the second dynamic scheduling signaling of the first user equipment is at least one user of the second user equipment. The length of the second dynamic scheduling signaling of the device is different, and the length of the second dynamic scheduling signaling of the first user equipment is used to enable the first user equipment to determine the second dynamic scheduling that carries the first user equipment according to the length. Signaling information bits.
具体而言, 例如, 网络设备可以向 UE以单播的方式发送信令, 通知第 二动态调度信令所包括的比特数 Nb的取值,并可以向不同 UE发送不同的值。 UE收到之后, 根据接收到的 Nb来确定信息位。 与前面的实施例不同, 网络 设备可以为不同的 UE配置不同的 Nb的取值, 确定的方法不限。 Specifically, for example, the network device may send signaling to the UE in a unicast manner, notify the value of the number of bits N b included in the second dynamic scheduling signaling, and may send different values to different UEs. After receiving the UE, the information bit is determined according to the received N b . Different from the previous embodiments, the network device may configure different values of N b for different UEs, and the method for determining is not limited.
例如, 网络设备可以根据不同 UE的信道波动情况来确定 Nb的取值。 例 如, 若根据 UE1反馈的信道情况发现 UE1的信道波动较快, 因此网络设备 可以为 UE1 配置较大的 Nb的取值; 通常 Nb的取值越大, 网络设备就可以在 向 UE1 发送第二动态调度信令时对调度具有更大的调整空间, 因而可以使 网络设备的可调整空间适应不同 UE的信道情况。 例如, 若 Nb=2, 则第二动 态调度信令仅能从 4种备选调度方案中确定一种; 若 Nb=3, 则第二动态调度 信令能从 8 种备选调度方案中确定一种。 或者, 网络设备也可以根据不同 UE的路径损耗来确定 Nb的取值。 通常路径损耗越大, 说明该 UE越靠近小 区的边缘, 通常信道波动也就越大, 这样也可以达到相同的效果。 For example, the network device may determine the value of N b according to channel fluctuation conditions of different UEs. For example, according to the channel condition if found UE1 UE1 feedback channel fluctuation is fast, the network device may be configured to a larger value of N b UE1; N b values generally greater, the network device may send to the UE1 in The second dynamic scheduling signaling has a larger adjustment space for scheduling, so that the adjustable space of the network device can be adapted to the channel conditions of different UEs. For example, if N b = 2, the second dynamic scheduling signaling can only determine one of the four alternative scheduling schemes; if N b = 3, the second dynamic scheduling signaling can be from eight alternative scheduling schemes Determine one of them. Alternatively, the network device may also determine the value of N b according to the path loss of different UEs. Generally, the larger the path loss, the closer the UE is to the edge of the cell, and the larger the channel fluctuation, the same effect can be achieved.
应理解, 在本发明实施例中, 上述各过程的序号的大小并不意味着执行 顺序的先后, 各过程的执行顺序应以其功能和内在逻辑确定, 而不应对本发 明实施例的实施过程构成任何限定。 例如, S140可以在 S110或 S120之后, 也可以在 S110或 S120之前, 本发明实施例并不限于此。 It should be understood that, in the embodiment of the present invention, the size of the sequence numbers of the foregoing processes does not mean the order of execution sequence, and the execution order of each process should be determined by its function and internal logic, and should not be implemented in the embodiment of the present invention. Form any limit. For example, S140 may be after S110 or S120, It is also possible before Embodiment S110 or S120, and the embodiment of the present invention is not limited thereto.
在本发明实施例中, 可选地, 该第一用户设备的第二动态调度信令包括 的调度信息的种类为该第一动态调度信令包括的调度信息的种类中的至少 一种。  In the embodiment of the present invention, the type of the scheduling information included in the second dynamic scheduling signaling of the first user equipment is at least one of the types of scheduling information included in the first dynamic scheduling signaling.
应理解, 在本发明实施例中, 该第一用户设备的第二动态调度信令可以 包括网络设备最终确定的调度方案,也可以包括与第一动态调度信令中的调 度信息相比而言的调整值或调整量。  It should be understood that, in the embodiment of the present invention, the second dynamic scheduling signaling of the first user equipment may include a scheduling scheme finally determined by the network device, and may also include comparing with scheduling information in the first dynamic scheduling signaling. The adjustment value or adjustment amount.
例如,对于第一动态调度信令中与第一用户设备的第二动态调度信令具 有相同属性或种类的调度信息, 第一用户设备的第二动态调度信令是对第一 动态调度信令的调整。 例如, 第一动态调度信令和第二动态调度信令都包括 MCS信息, 第一动态调度信令包括 5比特, 可以最多指示 32个 MCS级另1 J , 不同阶的 MCS 对应不同的调制方式和 /或编码速率。 若第一动态信令指示 MCS级别为 10,第二动态调度信令指示 MCS级别的偏移量为 +5,则最终向 UE发送 PDSCH所使用的 MCS级别或接收 UE发送的 PUSCH所使用的 MCS 级别就为 15。 For example, for the first dynamic scheduling signaling, the second dynamic scheduling signaling of the first user equipment has the same attribute or type of scheduling information, and the second dynamic scheduling signaling of the first user equipment is the first dynamic scheduling signaling. Adjustment. For example, the first dynamic scheduling signaling and the second dynamic scheduling signaling both include MCS information, and the first dynamic scheduling signaling includes 5 bits, and may indicate up to 32 MCS levels and another 1 J. Different order MCSs correspond to different modulation modes. And / or encoding rate. If the first dynamic signaling indicates that the MCS level is 10, and the second dynamic scheduling signaling indicates that the offset of the MCS level is +5, the MCS level used by the PDSCH or the MCS used by the PUSCH sent by the UE is finally sent to the UE. The level is 15.
应理解, 第一用户设备的第二动态调度信令的调度信息的种类也可以包 括第一动态调度信令没有的调度信息的种类, 本发明实施例并不以此为限。  It should be understood that the type of the scheduling information of the second dynamic scheduling signaling of the first user equipment may also include the type of the scheduling information that is not included in the first dynamic scheduling signaling, which is not limited thereto.
在本发明实施例中, 可选地, 在该第一用户设备的第二动态调度信令包 括的调度信息的种类与该第一动态调度信令包括的调度信息的种类相同时, 该第一动态调度信令用于指示调度信息的备选项子集, 该第一用户设备的第 二动态调度信令用于指示该备选项子集中的一个元素。  In the embodiment of the present invention, optionally, when the type of the scheduling information included in the second dynamic scheduling signaling of the first user equipment is the same as the type of the scheduling information included in the first dynamic scheduling signaling, the first The dynamic scheduling signaling is used to indicate a subset of the scheduling information, and the second dynamic scheduling signaling of the first user equipment is used to indicate an element in the subset of the alternative.
例如, MCS的级别即是一个调度信息, 目前 LTE系统中最多支持 32个 MCS的备选级别, 这 32个 MCS级别可以被划分为 8个子集, 例如如表 1 所示:  For example, the MCS level is a scheduling information. At present, the LTE system supports up to 32 MCS candidate levels. The 32 MCS levels can be divided into 8 subsets, as shown in Table 1:
表 1  Table 1

111 7 28- -31 00,01,10,11 网络设备可以首先通过第一动态调度信令向 UE发送 MCS子集信息, 例如, 该子集信息为 011 , 即表示所选定的子集编号为 3; 网络设备可以再 通过第二动态调度信令, 向 UE发送在所确定的 MCS 子集中最终确定的 MCS, 例如 MCS级别信息为 01 , 即表示最终选定的 MCS为 13。 通过这样 的方式, 可以实现通过 5比特向 UE传递最终确定的 MCS的目的, 由此能 够节省系统开销, 提高资源利用率。 111 7 28- -31 00,01,10,11 The network device may first send the MCS subset information to the UE by using the first dynamic scheduling signaling, for example, the subset information is 011, that is, the selected subset number is The network device may send the MCS finally determined in the determined MCS subset by using the second dynamic scheduling signaling, for example, the MCS level information is 01, that is, the finally selected MCS is 13. In this way, the purpose of delivering the final determined MCS to the UE through 5 bits can be achieved, thereby saving system overhead and improving resource utilization.
在本发明实施例中, 可选地, 如图 3所述, 在向该第一用户设备发送下 行数据信号或接收该第一用户设备发送的上行数据信号之前, 该方法 100还 包括:  In the embodiment of the present invention, optionally, as shown in FIG. 3, before the sending the downlink data signal to the first user equipment or receiving the uplink data signal sent by the first user equipment, the method 100 further includes:
S150, 向该第一用户设备发送调整粒度, 其中, 该调整粒度用于使得该 第一用户设备根据该调整粒度调整该第一用户设备的第二动态调度信令包 括的调度信息的取值。  S150. The adjustment granularity is sent to the first user equipment, where the adjustment granularity is used to adjust, by the first user equipment, the value of the scheduling information included in the second dynamic scheduling signaling of the first user equipment according to the adjusted granularity.
具体而言, 例如, 网络设备可以向 UE以单播的方式发送信令通知调整 粒度的取值, UE 可以根据该调整粒度与第二动态调度信令中的信息, 确定 最终的调度方案。  Specifically, for example, the network device may send a signaling to the UE in a unicast manner to adjust the value of the granularity, and the UE may determine the final scheduling scheme according to the adjusted granularity and the information in the second dynamic scheduling signaling.
例如, 为了达到为不同 UE 配置不同的调度空间的目的, 除了为不同 UE配置不同的 Nb的取值之外, 还可以为不同 UE配置不同的调度调整粒度。 例如,第二动态调度信令包括 2个比特,分别表示 4种状态,如下表 2所示。 若网络设备向 UE发送第二动态调度信令为 11 , 则 UE就会将 MCS P介数向 上调整 2xG, 即若第一动态调度信令中指示初始的 MCS P介数为 10, 则 UE 收到第二动态调度信令之后, 就确定最终调度的 MCS P介数为 10+2xG。 For example, in order to achieve different scheduling spaces for different UEs, in addition to configuring different values of N b for different UEs, different scheduling adjustment granularities may be configured for different UEs. For example, the second dynamic scheduling signaling includes 2 bits, which respectively represent 4 states, as shown in Table 2 below. If the network device sends the second dynamic scheduling signaling to the UE, the UE adjusts the MCS P medium by 2xG, that is, if the initial dynamic scheduling signaling indicates that the initial MCS P is 10, the UE receives After the second dynamic scheduling signaling, it is determined that the final scheduled MCS P median is 10+2xG.
表 2  Table 2
Figure imgf000031_0001
Figure imgf000031_0001
通过对调度粒度的调整, 同样达到了为不同 UE配置不同调整范围的目 的, 例如对于信道波动剧烈的 UE, 可以为其配置较大的 G值, 从而就能使 MCS调整阶数的范围较大。 By adjusting the scheduling granularity, the same adjustment range is configured for different UEs. For example, for a UE with severe channel fluctuations, a larger G value can be configured for it, so that the range of the MCS adjustment order can be made larger.
应理解, 在本发明实施例中, 网络设备可以首先使用根据第一动态调度 信令和第二动态调度信令确定的调度方案对 UE发送的上行数据信号进行解 码, 如果解码不成功, 则网络设备可以仅使用根据第一动态调度信令确定的 调度方案对 UE发送给的上行数据信号进行解码。 通过这样的方式, 可以避 免第二动态调度信令没有被 UE收到而造成的网络设备和 UE对调度方案的 理解不一致所造成的混淆。  It should be understood that, in the embodiment of the present invention, the network device may first decode the uplink data signal sent by the UE according to the scheduling scheme determined according to the first dynamic scheduling signaling and the second dynamic scheduling signaling, and if the decoding is unsuccessful, the network The device may decode the uplink data signal sent by the UE using only the scheduling scheme determined according to the first dynamic scheduling signaling. In this way, confusion caused by inconsistent understanding of the scheduling scheme between the network device and the UE caused by the second dynamic scheduling signaling not being received by the UE can be avoided.
应理解, 在本发明的各种实施例中, 上述各过程的序号的大小并不意味 着执行顺序的先后, 各过程的执行顺序应以其功能和内在逻辑确定, 而不应 对本发明实施例的实施过程构成任何限定。  It should be understood that, in various embodiments of the present invention, the size of the sequence numbers of the above processes does not mean the order of execution, and the order of execution of each process should be determined by its function and internal logic, and should not be taken to the embodiments of the present invention. The implementation process constitutes any limitation.
因此, 本发明实施例的调度无线资源的方法, 通过采用两个动态调度信 令为用户设备调度上行或下行资源, 能够使得调度方案更好地适应信道环境 的变化, 从而能够提高信号传输的可靠性, 提高用户体验; 另一方面, 网络 设备在第一动态调度信令中还承载第二动态调度信令中的信息的索引,便于 网络设备动态地向被调度的 UE指示发送第二动态调度信令所使用的信息 位, 从而能够充分利用有限的信息位来满足为多个 UE的调度, 以降低动态 调度信令所需要的信息位资源开销, 增强本发明的可行性。  Therefore, the method for scheduling radio resources in the embodiment of the present invention can use the two dynamic scheduling signaling to schedule uplink or downlink resources for the user equipment, so that the scheduling scheme can better adapt to changes in the channel environment, thereby improving signal transmission reliability. On the other hand, the network device also carries the index of the information in the second dynamic scheduling signaling in the first dynamic scheduling signaling, so that the network device dynamically sends the second dynamic scheduling to the scheduled UE. The information bits used by the signaling can fully utilize the limited information bits to satisfy the scheduling for multiple UEs, so as to reduce the information bit resource overhead required for dynamic scheduling signaling, and enhance the feasibility of the present invention.
图 4示出了根据本发明实施例的调度无线资源的方法 200, 该方法 200 可以由网络设备执行。 如图 4所示, 该方法 200包括:  4 illustrates a method 200 of scheduling radio resources, which may be performed by a network device, in accordance with an embodiment of the present invention. As shown in FIG. 4, the method 200 includes:
S210, 向用户设备发送第一动态调度信令, 该第一动态调度信令包括用 于指示频率资源的频率信息和用于指示是否调整调度方案的索引信息;  S210. The first dynamic scheduling signaling is sent to the user equipment, where the first dynamic scheduling signaling includes frequency information for indicating a frequency resource and index information for indicating whether to adjust the scheduling scheme.
S220, 在该索引信息指示调整调度方案时, 根据该索引信息确定用于承 载第二动态调度信令的信息位; 在该信息位上向该用户设备发送该第二动态 调度信令; 在该频率信息指示的该频率资源上, 根据该第二动态调度信令向 该用户设备发送下行数据信号, 或者在该频率信息指示的该频率资源上, 接 收该用户设备根据该第二动态调度信令发送的上行数据信号;  S220, when the index information indicates that the scheduling scheme is adjusted, determining, according to the index information, an information bit for carrying the second dynamic scheduling signaling; sending, by the information bit, the second dynamic scheduling signaling to the user equipment; And transmitting, by the second dynamic scheduling signaling, the downlink data signal to the user equipment according to the second dynamic scheduling signaling, or receiving, by the user equipment, the second dynamic scheduling signaling according to the frequency resource indicated by the frequency information. The uplink data signal sent;
S230, 在该索引信息指示不调整调度方案时, 在该频率信息指示的该频 率资源上, 根据该第一动态调度信令向该用户设备发送下行数据信号, 或者 在该频率信息指示的该频率资源上,接收该用户设备根据该第一动态调度信 令发送的上行数据信号。 具体而言, 索引信息的所有备选项中可以至少包括一个备选项, 用于指 示 UE不调整调度方案; 网络设备可以在第一动态调度信令中向 UE发送包 括此备选项的索引信息, UE收到之后, 就不在第二时段检测第二动态调度 信令中的信息。 S230, when the index information indicates that the scheduling scheme is not adjusted, sending, by using the first dynamic scheduling signaling, a downlink data signal, or the frequency indicated by the frequency information, on the frequency resource indicated by the frequency information. And receiving, by the resource, an uplink data signal sent by the user equipment according to the first dynamic scheduling signaling. Specifically, all the options of the index information may include at least one candidate for indicating that the UE does not adjust the scheduling scheme. The network device may send the index information including the candidate to the UE in the first dynamic scheduling signaling, where the UE After receiving, the information in the second dynamic scheduling signaling is not detected in the second time period.
例如, 第一动态调度信令中的索引信息包括 5个比特, 其中 "00000" 用于指示 UE不调整调度方案。 UE收到该指示之后, 就可以不在第二时段 检测第二动态调度信令中的信息, 而可以直接根据第一动态调度信令的调度 信息来确定最终的调度方案。 由此可以降低 UE的复杂度, 也可以以更少的 第二动态调度信令开销来满足同一 ΤΉ调度较多 UE的情况。  For example, the index information in the first dynamic scheduling signaling includes 5 bits, where "00000" is used to indicate that the UE does not adjust the scheduling scheme. After receiving the indication, the UE may not detect the information in the second dynamic scheduling signaling in the second time period, but may directly determine the final scheduling solution according to the scheduling information of the first dynamic scheduling signaling. Therefore, the complexity of the UE can be reduced, and the second dynamic scheduling signaling overhead can be used to satisfy the situation in which more UEs are scheduled.
例如, 某个 ΤΉ中调度了 30个 UE, 而第二动态调度信令最多只能支持 向 20个 UE发送第二动态调度信令,则网络设备可以向 10个 UE发送" 00000" 的索引信息, 从而网络设备就只需在第二时段为其它 20个 UE发送第二动 态调度信令即可, 而不需 30个第二动态调度信令。 由此能够节省系统开销, 提高资源利用率。  For example, if 30 UEs are scheduled in a certain cell, and the second dynamic scheduling signaling can only support sending the second dynamic scheduling signaling to 20 UEs at most, the network device can send index information of "00000" to 10 UEs. Therefore, the network device only needs to send the second dynamic scheduling signaling to the other 20 UEs in the second time period, and does not need 30 second dynamic scheduling signaling. This saves system overhead and improves resource utilization.
应理解, 调度无线资源的方法 200中描述的 UE与网络设备之间的交互 及相关特性、 功能等与调度无线资源的方法 100中的相关描述相应, 为了筒 洁, 在此不再赘述。  It should be understood that the interaction between the UE and the network device and the related features, functions, and the like described in the method for scheduling the radio resource 200 are related to the related description in the method 100 for scheduling the radio resource, and are not described herein again.
因此, 本发明实施例的调度无线资源的方法, 通过采用两个动态调度信 令为用户设备调度上行或下行资源, 能够使得调度方案更好地适应信道环境 的变化, 从而能够提高信号传输的可靠性, 提高用户体验。  Therefore, the method for scheduling radio resources in the embodiment of the present invention can use the two dynamic scheduling signaling to schedule uplink or downlink resources for the user equipment, so that the scheduling scheme can better adapt to changes in the channel environment, thereby improving signal transmission reliability. Sex, improve the user experience.
另一方面, 网络设备在第一动态调度信令中还承载用于指示是否调整调 度方案的索引信息, 以便于网络设备动态地向被调度的 UE指示是否对第一 动态调度信令包括的调度方案进行调整,从而能够充分利用有限的资源来调 度更多的 UE, 以降低系统资源开销, 提高资源利用率。  On the other hand, the network device further carries, in the first dynamic scheduling signaling, index information for indicating whether to adjust the scheduling scheme, so that the network device dynamically indicates to the scheduled UE whether the scheduling included in the first dynamic scheduling signaling is included. The solution is adjusted so that more resources can be utilized to schedule more UEs to reduce system resource overhead and improve resource utilization.
上文中结合图 1至图 4, 从网络设备的角度详细描述了根据本发明实施 例的调度无线资源的方法, 下面将结合图 5至图 9, 从用户设备的角度描述 根据本发明实施例的调度无线资源的方法。  With reference to FIG. 1 to FIG. 4, a method for scheduling radio resources according to an embodiment of the present invention is described in detail from the perspective of a network device, and a description will be made from the perspective of a user equipment according to an embodiment of the present invention with reference to FIG. 5 to FIG.

图 5示出了根据本发明实施例的调度无线资源的方法 300, 该方法 300 例如可以由第一用户设备执行。 如图 5所示, 该方法 300包括:  FIG. 5 illustrates a method 300 of scheduling radio resources, which may be performed, for example, by a first user equipment, in accordance with an embodiment of the present invention.

The second dynamic scheduling signaling of the first user equipment sends an uplink data signal to the network device.
因此, 本发明实施例的调度无线资源的方法, 通过采用两个动态调度信 令为用户设备调度上行或下行资源, 能够使得调度方案更好地适应信道环境 的变化, 从而能够提高信号传输的可靠性, 提高用户体验。  Therefore, the method for scheduling radio resources in the embodiment of the present invention can use the two dynamic scheduling signaling to schedule uplink or downlink resources for the user equipment, so that the scheduling scheme can better adapt to changes in the channel environment, thereby improving signal transmission reliability. Sex, improve the user experience.
另一方面, 用户设备还可以根据第一动态调度信令中承载的第二动态调 度信令的信息索引, 确定网络设备发送第二动态调度信令所使用的信息位, 从而能够充分利用有限的信息位来实现多个 UE的调度, 由此能够降低动态 调度信令所需要的信息位资源开销, 提高资源利用率。  On the other hand, the user equipment may further determine, according to the information index of the second dynamic scheduling signaling carried in the first dynamic scheduling signaling, the information bits used by the network device to send the second dynamic scheduling signaling, so as to fully utilize the limited information. The information bits are used to implement scheduling of multiple UEs, thereby reducing the information bit resource overhead required for dynamic scheduling signaling and improving resource utilization.

还应理解, 在本发明实施例中, 该第一用户设备的第二动态调度信令可 以包括网络设备最终确定的调度方案,也可以包括各调度信息与第一动态调 度信令中的调度方案相比而言的调整值或调整量。 具体而言, 例如, 调制方 式信息可以包括最终的调制方式, 也可以包括调制方式的调整值; 编码速率 信息可以包括最终的编码速率, 也可以包括编码速率的调整值。  It should be further understood that, in the embodiment of the present invention, the second dynamic scheduling signaling of the first user equipment may include a scheduling scheme finally determined by the network device, and may also include scheduling information in each scheduling information and the first dynamic scheduling signaling. The adjustment value or adjustment amount compared to the comparison. Specifically, for example, the modulation mode information may include a final modulation mode, and may also include an adjustment value of the modulation mode; the coding rate information may include a final coding rate, and may also include an adjustment value of the coding rate.
还应理解, 第一用户设备的第二动态调度信令还可以包括所发送的信号 所承载的频带、 所发送的信号采用的层数、 所发送的信号所采用的预编码矩 阵、 发送信号所选择的天线端口等信息, 本发明实施例并不限于此。  It should also be understood that the second dynamic scheduling signaling of the first user equipment may further include a frequency band carried by the transmitted signal, a layer used by the transmitted signal, a precoding matrix used by the transmitted signal, and a transmission signal. The information of the selected antenna port and the like, the embodiment of the present invention is not limited thereto.
在本发明实施例中,可选地,该接收网络设备发送的第一动态调度信令, 包括:  In the embodiment of the present invention, optionally, the first dynamic scheduling signaling sent by the receiving network device includes:
在第一时段, 接收该网络设备发送的该第一动态调度信令;  Receiving, by the first time period, the first dynamic scheduling signaling sent by the network device;
该在该索引信息指示的该信息位上接收该网络设备发送的第一用户设 备的第二动态调度信令, 包括:  Receiving, by the information bit indicated by the index information, the second dynamic scheduling signaling of the first user equipment sent by the network device, including:
在第二时段,在该信息位上接收该网络设备发送的该第一用户设备的第 二动态调度信令,其中,该第一时段与该第二时段属于不同的传输时间间隔。 即接收该网络设备发送的该第一动态调度信令的第一时段, 与接收该网 络设备发送的该第一用户设备的第二动态调度信令的第二时段属于不同的 传输时间间隔 TTI。 可选地, 第一用户设备接收网络设备发送第一用户设备 的第二动态调度信令的第二时段, 与用户设备接收网络设备根据该第一用户 设备的第二动态调度信令向第一用户设备发送下行数据信号的第三时段属 于相同的 ΤΤΙ。 Receiving, in the second time period, the second dynamic scheduling signaling of the first user equipment that is sent by the network device, where the first time period and the second time period belong to different transmission time intervals. That is, the first time period of receiving the first dynamic scheduling signaling sent by the network device belongs to a different transmission time interval TTI from the second time period of receiving the second dynamic scheduling signaling of the first user equipment sent by the network device. Optionally, the first user equipment receives a second time period in which the network device sends the second dynamic scheduling signaling of the first user equipment, and the user equipment receiving network equipment is first according to the second dynamic scheduling signaling of the first user equipment. The third period in which the user equipment sends the downlink data signal belongs to the same frame.
应理解, 在本发明实施例中, 第一用户设备确定信息位的时刻与第一时 刻或第二时刻可以属于相同的 ΤΉ, 也可以属于不同的 ΤΉ, 本发明实施例 并不限于此。  It should be understood that, in the embodiment of the present invention, the time at which the first user equipment determines the information bit may be the same as the first time or the second time, and may also belong to different ΤΉ, and the embodiment of the present invention is not limited thereto.
还应理解, 通常在一个通信系统中, 会将时间维度以某一长度为单位进 行划分。 例如在 LTE系统中, 以 ΤΉ为单位对时间维度进行划分, 1个 ΤΤΙ 的时间长度为 lms。 并且由于传输的时延, 网络设备与用户设备会对同样的 绝对时间进行不同的划分, 例如网络设备发送某个 ΤΉ, UE会延迟收到, 因此两者理解的 ΤΉ不同。本发明所述的时刻表示某项操作所处于的时间段 的编号, 例如可以为 ΤΉ的编号。  It should also be understood that the time dimension is typically divided by a certain length in a communication system. For example, in the LTE system, the time dimension is divided in units of ,, and the length of one ΤΤΙ is lms. And because of the delay of the transmission, the network device and the user equipment will divide the same absolute time differently. For example, if the network device sends a certain ΤΉ, the UE will delay the reception, so the two understand different ΤΉ. The time instant described in the present invention indicates the number of the time period in which an operation is located, and may be, for example, a number of ΤΉ.
在本发明实施例中, 可选地, 该第一用户设备的第二动态调度信令包括 功率控制信息, 在 S320中, 该根据该第一用户设备的第二动态调度信令向 该网络设备发送上行数据信号, 包括:  In the embodiment of the present invention, optionally, the second dynamic scheduling signaling of the first user equipment includes power control information, and in S320, the second dynamic scheduling signaling according to the first user equipment is used to the network device. Sending uplink data signals, including:

And the location of the second dynamic scheduling signaling of each user equipment in the signaling packet is corresponding to the information bit of the second dynamic scheduling signaling used by the network device to be used according to the index information to carry the user equipment.

在本发明实施例中, 可选地, 该第一用户设备和该第二用户设备被调度 的传输时间间隔的编号相同。 即该信令包包括的各第二动态调度信令所属的 各用户设备被调度的传输时间间隔相同。 可选地, 该组标识符的值根据该第 一用户设备所属的小区的标识确定。 可选地, 该组标识符的值根据该第一用 户设备被调度时的传输时间间隔的编号确定。 可选地, 该信令包的大小为固 定值; 或该信令包的大小为该网络设备通过广播通知的第一值; 或该信令包 的大小根据系统带宽、动态调度信令的资源容量和该索引信息的比特数目中 的至少一种信息确定。  In the embodiment of the present invention, optionally, the first user equipment and the second user equipment are scheduled to have the same transmission time interval. That is, each user equipment to which each second dynamic scheduling signaling included in the signaling packet belongs has the same transmission time interval. Optionally, the value of the group identifier is determined according to the identity of the cell to which the first user equipment belongs. Optionally, the value of the group identifier is determined according to the number of the transmission time interval when the first user equipment is scheduled. Optionally, the size of the signaling packet is a fixed value; or the size of the signaling packet is a first value notified by the network device by using a broadcast; or the size of the signaling packet is based on a system bandwidth, and dynamically scheduling signaling resources.

可选地, 该索引信息的比特数目为固定值; 或该索引信息的比特数目为 该网络设备通过广播通知的第二值; 或该索引信息的比特数目根据系统带宽 和动态调度信令的资源容量中的至少一种信息确定。  Optionally, the number of bits of the index information is a fixed value; or the number of bits of the index information is a second value notified by the network device by broadcast; or the number of bits of the index information is based on system bandwidth and resources for dynamically scheduling signaling At least one of the capacities is determined.
可选地,该信令包包括的该第一用户设备和该第二用户设备的第二动态 调度信令的长度相同。 即该信令包包括的各用户设备的第二动态调度信令的 长度相同。 可选地, 该第一用户设备的第二动态调度信令的长度为预存值; 或该第一用户设备的第二动态调度信令的长度为该网络设备通过广播通知 的第三值。 在本发明实施例中, 可选地, 如图 6所示, 在接收该网络设备发送的下 行数据信号或向该网络设备发送下行数据信号之前, 该方法 300还包括:Optionally, the first user equipment included in the signaling packet and the second dynamic scheduling signaling of the second user equipment are the same length. That is, the length of the second dynamic scheduling signaling of each user equipment included in the signaling packet is the same. Optionally, the length of the second dynamic scheduling signaling of the first user equipment is a pre-stored value; or the length of the second dynamic scheduling signaling of the first user equipment is a third value that is notified by the network device by using a broadcast. In the embodiment of the present invention, optionally, as shown in FIG. 6, before receiving the downlink data signal sent by the network device or sending the downlink data signal to the network device, the method 300 further includes:
S340,接收该网络设备发送的该第一用户设备的第二动态调度信令的长 度, 该第一用户设备的第二动态调度信令的长度与该第二用户设备中的至少 一个用户设备的第二动态调度信令的长度不同; S340, the length of the second dynamic scheduling signaling of the first user equipment that is sent by the network device, the length of the second dynamic scheduling signaling of the first user equipment, and the length of the at least one user equipment of the second user equipment The length of the second dynamic scheduling signaling is different;
S350, 根据该索引信息和该第一用户设备的第二动态调度信令的长度, 确定用于承载该第一用户设备的第二动态调度信令的信息位。  S350. Determine, according to the index information and a length of the second dynamic scheduling signaling of the first user equipment, information bits used to carry the second dynamic scheduling signaling of the first user equipment.
因此, 第一用户设备可以在所确定的该信息位上, 接收网络设备发送的 第一用户设备的第二动态调度信令。  Therefore, the first user equipment may receive the second dynamic scheduling signaling of the first user equipment sent by the network device on the determined information bit.
具体而言, 例如, 网络设备可以向 UE以单播的方式发送信令, 通知第 二动态调度信令所包括的比特数 Nb的取值,并可以向不同 UE发送不同的值。 UE收到之后, 根据接收到的 Nb来确定信息位。 与前面的实施例不同, 网络 设备可以为不同的 UE配置不同的 Nb的取值, 确定的方法不限。 Specifically, for example, the network device may send signaling to the UE in a unicast manner, notify the value of the number of bits N b included in the second dynamic scheduling signaling, and may send different values to different UEs. After receiving the UE, the information bit is determined according to the received N b . Different from the previous embodiments, the network device may configure different values of N b for different UEs, and the method for determining is not limited.
例如, 网络设备可以根据不同 UE的信道波动情况来确定 Nb的取值。 例 如, 若根据 UE1反馈的信道情况发现 UE1的信道波动较快, 因此网络设备 可以为 UE1 配置较大的 Nb的取值; 通常 Nb的取值越大, 网络设备就可以在 向 UE1 发送第二动态调度信令时对调度具有更大的调整空间, 因而可以使 网络设备的可调整空间适应不同 UE的信道情况。 例如, 若 Nb=2, 则第二动 态调度信令仅能从 4种备选调度方案中确定一种; 若 Nb=3, 则第二动态调度 信令能从 8 种备选调度方案中确定一种。 或者, 网络设备也可以根据不同 UE的路径损耗来确定 Nb的取值。 通常路径损耗越大, 说明该 UE越靠近小 区的边缘, 通常信道波动也就越大, 这样也可以达到相同的效果。 For example, the network device may determine the value of N b according to channel fluctuation conditions of different UEs. For example, according to the channel condition if found UE1 UE1 feedback channel fluctuation is fast, the network device may be configured to a larger value of N b UE1; N b values generally greater, the network device may send to the UE1 in The second dynamic scheduling signaling has a larger adjustment space for scheduling, so that the adjustable space of the network device can be adapted to the channel conditions of different UEs. For example, if N b = 2, the second dynamic scheduling signaling can only determine one of the four alternative scheduling schemes; if N b = 3, the second dynamic scheduling signaling can be from eight alternative scheduling schemes Determine one of them. Alternatively, the network device may also determine the value of N b according to the path loss of different UEs. Generally, the larger the path loss, the closer the UE is to the edge of the cell, and the larger the channel fluctuation, the same effect can be achieved.
在本发明实施例中, 可选地, 该第一用户设备的第二动态调度信令包括 的调度信息的种类为该第一动态调度信令包括的调度信息的种类中的至少 一种。  In the embodiment of the present invention, the type of the scheduling information included in the second dynamic scheduling signaling of the first user equipment is at least one of the types of scheduling information included in the first dynamic scheduling signaling.
在本发明实施例中, 可选地, 在该第一用户设备的用户设备的第二动态 调度信令包括的调度信息的种类与该第一动态调度信令包括的调度信息的 种类相同时, 该第一动态调度信令用于指示调度信息的备选项子集, 该第一 用户设备的第二动态调度信令用于指示该备选项子集中的一个元素。  In the embodiment of the present invention, optionally, when the type of the scheduling information included in the second dynamic scheduling signaling of the user equipment of the first user equipment is the same as the type of the scheduling information included in the first dynamic scheduling signaling, The first dynamic scheduling signaling is used to indicate a subset of the scheduling information, and the second dynamic scheduling signaling of the first user equipment is used to indicate an element in the alternative subset.
在本发明实施例中, 可选地, 如图 7所示, 在接收该网络设备发送的下 行数据信号或向该网络设备发送下行数据信号之前, 该方法 300还包括: S360,接收该网络设备发送的该第一用户设备的第二动态调度信令的调 整粒度; In the embodiment of the present invention, optionally, as shown in FIG. 7, before receiving the downlink data signal sent by the network device or sending the downlink data signal to the network device, the method 300 further includes: S360. Receive an adjustment granularity of the second dynamic scheduling signaling of the first user equipment sent by the network device.
S370, 根据该调整粒度, 确定该第一用户设备的第二动态调度信令包括 的调度信息的取值。  S370. Determine, according to the adjusted granularity, a value of scheduling information included in the second dynamic scheduling signaling of the first user equipment.
在本发明实施例中, 可选地, 如图 8所示, 在接收该网络设备发送的所 述第一动态调度信令之后, 该方法 300还包括:  In the embodiment of the present invention, optionally, as shown in FIG. 8, after receiving the first dynamic scheduling signaling sent by the network device, the method 300 further includes:
S380,在没有接收到该网络设备发送的该第一用户设备的第二动态调度 信令时, 在该频率信息指示的该频率资源上, 根据该第一动态调度信令向该 网络设备发送上行数据信号。  S380, when the second dynamic scheduling signaling of the first user equipment that is sent by the network device is not received, send, to the network device, the uplink according to the first dynamic scheduling signaling on the frequency resource indicated by the frequency information. Data signal.
具体而言, 对于上行传输来说, 若 UE检测到网络设备发送的第一动态 调度信令和第二动态调度信令, 则 UE可以根据这两个动态调度信令确定最 终的调度方案, 并可以根据该方案发送上行数据信号; 若 UE仅检测到网络 设备发送的第一动态调度信令, 则 UE可以根据第一动态调度信令确定最终 的调度方案, 并可以根据该方案发送上行数据信号。  Specifically, for the uplink transmission, if the UE detects the first dynamic scheduling signaling and the second dynamic scheduling signaling sent by the network device, the UE may determine the final scheduling solution according to the two dynamic scheduling signaling, and The uplink data signal may be sent according to the scheme. If the UE only detects the first dynamic scheduling signaling sent by the network device, the UE may determine the final scheduling scheme according to the first dynamic scheduling signaling, and may send the uplink data signal according to the scheme. .
例如, 网络设备向 UE发送第一动态调度信令, 其中包括使用级别为 10 的 MCS的信息; 然后向 UE发送第二动态调度信令, 其中包括 MCS级别调 整值为 +3。 若 UE收到了第一动态调度信令和第二动态调度信令, 则 UE可 以使用级别为 13的 MCS对上行数据进行调制和编码; 若 UE仅受到第一动 态调度信令,则 UE可以使用级别为 10的 MCS对上行数据进行调制和编码。 对于网络设备来说,可以先使用级别为 13的 MCS对上行数据进行解调和解 码, 若解码不正确, 则可以使用级别为 10的 MCS对上行数据进行解调和解 码。  For example, the network device sends the first dynamic scheduling signaling to the UE, including using the information of the MCS of level 10; and then sends the second dynamic scheduling signaling to the UE, including the MCS level adjustment value of +3. If the UE receives the first dynamic scheduling signaling and the second dynamic scheduling signaling, the UE may modulate and encode the uplink data by using the MCS of level 13; if the UE is only subjected to the first dynamic scheduling signaling, the UE may use The MCS at level 10 modulates and encodes the upstream data. For the network device, the uplink data may be demodulated and decoded by using the MCS of level 13. If the decoding is not correct, the uplink data may be demodulated and decoded using the MCS of level 10.
通过这样的方式, 可以避免第二动态调度信令没有被 UE收到而造成的 网络设备和 UE对调度方案的理解不一致所造成的混淆。  In this way, confusion caused by inconsistent understanding of the scheduling scheme between the network device and the UE caused by the second dynamic scheduling signaling not being received by the UE can be avoided.
应理解, UE侧描述的 UE与网络设备的交互及相关特性、 功能等与网 络设备侧的描述相应, 为了筒洁, 在此不再赘述。  It should be understood that the interaction between the UE and the network device described in the UE side and related features, functions, and the like are corresponding to the description on the network device side, and are not described herein again.
