- the uplink data mentioned in the embodiments of the present disclosure refers to data sent by the terminal to the network device, which may be data transmitted via the PUSCH.
- the method before determining the transmission resource according to the meta-bit corresponding to the uplink data, the method further includes:
- the resource configuration information includes at least one of the following: the number of time slots, the number of resources in each time slot, the time domain symbol resource position, the frequency domain resource position, and an orthogonal sequence set.
- the number of time slots refers to the number of time slots occupied by at least one transmission resource; the number of resources in each time slot refers to the number of transmission opportunities of the transmission resource existing in each time slot; the time domain symbol resource position refers to the time domain symbol occupied by each transmission resource.

- the orthogonal sequence set may include the number of orthogonal sequences in the time domain, the value of the initial cyclic shift (cyclic shift) on each PRB, and the number of cyclic shifts on each PRB.
- the terminal can know the total number of transmission resources specifically configured by the network device through the resource configuration information. Since the location of the transmission resources is related to the I, Q signals, time domain, and frequency domain, when the network device configures the resources, it can associate the transmission resources corresponding to each identifier by sorting them from small to large based on the resource identifiers, first based on I, Q, then frequency domain, and finally time domain.
- the transmission resource may be a physical downlink feedback channel (PDFCH) resource.
- PDFCH physical downlink feedback channel
- each transmission resource corresponds to an identifier (ie, a resource identifier); in some embodiments, the identifier may be a number or index of the resource.
- the network device configures at least one transmission resource for the terminal for transmitting the feedback information corresponding to the uplink data, and the terminal needs to determine one or more transmission resources actually required to be detected from these transmission resources based on the meta-bit.
- determining the transmission resource according to the meta-bit corresponding to the uplink data includes:
- the resource corresponding to the target identifier is determined as the transmission resource.
- determining the target identifier according to the meta bit corresponding to the uplink data includes one of the following implementations:
- Implementation method 1 using the element bit to perform a modulo operation on the total number of transmission resources configured by the network device to obtain a target identifier;
- a target identifier can be determined by operating on the meta-bit, and the target identifier corresponds to the identifier of the transmission resource and is used to indicate a unique transmission resource.
- Implementation method 2 inputting the meta-bit into a preset encoder, and determining the output result as the target identifier;
- the number of bits output by the preset encoder should be greater than or equal to the target number of bits, which is the minimum number of bits that can represent the total number of transmission resources configured by the network device.
- the number of bits output by the preset encoder should be equal to the target number of bits.
- the length of the meta-bit corresponding to the uplink data sent by the terminal is 16 bits
- the 16 bits are input to the encoder, and the encoder outputs 8 bits.
- the encoder is implemented by performing an XOR operation on the first and second bits of the input to obtain the first bit of the output, performing an XOR operation on the third and fourth bits of the input to obtain the second bit of the output, ..., performing an XOR operation on the fifteenth and sixteenth bits of the input to obtain the eighth bit of the output, and the index corresponding to the 8-bit output result is one of 0 to 255, which is the corresponding identifier of the transmission resource.
- the network device needs to use transmission resources to send feedback information, the two should have the same understanding of resources, so the network device side should use the same implementation method as the terminal side to obtain the target identifier.
- the network device can determine the transmission resources only if it detects the meta bits sent by the terminal. If the network device does not detect the meta bits sent by the terminal, the network device will not perform the subsequent process of determining the transmission resources.
- the network device after determining the transmission resource for sending the feedback information, the network device needs to send the feedback information of the uplink data to the terminal through the transmission resource.
- the network device side may receive uplink data from multiple terminals at the same time, it is necessary to determine the resources for transmitting feedback information corresponding to the uplink data of the multiple terminals respectively.
- the transmission resources finally determined by the network device correspond to at least two terminals, that is, the network device needs to send feedback information to at least two terminals on the transmission resources at the same time.
- the specific implementation of sending the feedback information of the uplink data to the terminal through the transmission resources includes at least one of the following:
- A11 If it is determined that uplink data of at least one terminal among the at least two terminals is not correctly received, send feedback information of the uplink data to the at least two terminals through the transmission resource, where the feedback information is used to indicate that the network device has not correctly received the uplink data;
- the network device needs to send a non-acknowledgement (NACK) to all terminals on the transmission resource, indicating that the network device has not received the uplink data correctly.
- NACK non-acknowledgement
- A12 If it is determined that the uplink data of at least one terminal among the at least two terminals is correctly received, feedback information of the uplink data is sent to the at least two terminals through the transmission resource, where the feedback information is used to indicate that the network device correctly receives the uplink data;
- the network device needs to send an acknowledgement (ACK) to all terminals on the transmission resource, that is, to indicate that the network device has correctly received the uplink data.
- ACK acknowledgement
- the network device if the network device correctly receives the uplink data of the terminal, the network device does not need to schedule retransmission for the terminal; if the network device does not correctly receive the uplink data of the terminal, if the retransmission mode is configured, the network device can schedule retransmission for the terminal, or, if the retransmission mode is not configured, the network device may not schedule retransmission for the terminal. If the network device needs to schedule retransmission, it needs to send downlink control information to the terminal, and the downlink control information is used to schedule the terminal to retransmit the uplink data. In some embodiments, the downlink control information can be scrambled using the meta bit.
- the terminal detects the feedback information of the uplink data sent by the network device on the transmission resource, if the feedback information indicates that the network device has not correctly received the uplink data, the meta bit is used to detect the downlink control information sent by the network device. Based on the detection result of the downlink control information, the terminal retransmits the uplink data at an appropriate position.
- the downlink control information is sent via a physical downlink control channel (PDCCH).
- PDCH physical downlink control channel
- the Physical Hybrid automatic repeat request Indicator Channel (PHICH) is used to feedback the response (ACK) or non-response (NACK) of the uplink data (e.g., PUSCH) transmission.
- the UE needs to first perform a blind detection of the PDCCH, and after failing to detect the PDCCH, continue to detect the PHICH on specific resources. This PDCCH blind detection may cause serious UE energy waste.
- the implementation method of the embodiment of the present disclosure directly determines the transmission resource for transmitting the feedback information corresponding to the uplink data based on the meta-bit, and then directly detects the feedback information on the transmission resource. Only when the feedback information indicates that the network device has not correctly received the uplink data, the PDCCH is detected. This cancels the process of blindly detecting the PDCCH before the feedback information, thereby reducing terminal power consumption and achieving terminal energy saving.
- the following takes the communication between a terminal and a base station as an example to illustrate the specific implementation of the embodiment of the present disclosure. Down.
- the terminal Taking the case where a terminal communicates with a base station, the terminal sends a PUSCH, and the base station sends feedback information through a PDFCH resource as an example, the specific implementation process of the embodiment of the present disclosure is as follows.
- the base station side process includes:
- Step 11 The base station sends resource configuration information to the terminal;
- the base station may transmit PDFCH common resource (pdfch-ResourceCommon) signaling via MIB or SIB to configure (or schedule) sufficient PDFCH resources for feedback information of uplink data.
- PDFCH common resource PDFch-ResourceCommon
- the pdfch-ResourceCommon signaling includes at least one of the following parameters:
- the time-frequency domain resources of each PRB and each slot can accommodate up to PDFCH, that is The total number of PDFCH resources configured for the base station, Indicates the total number of PDFCHs. According to the index of the PDFCH resource, first sort by I and Q, then sort by frequency domain, and finally sort by time domain to determine the final location of the PDFCH resource.
- Step 12 The base station determines, according to the received meta-bit sent by the terminal, a first resource for transmitting feedback information of uplink data of the terminal;
- the base station sends NACK at the resource position, or, in another case, the base station sends ACK at the resource position. Further, when the retransmission mode is configured, the base station retransmits for the terminal whose feedback information is NACK through PDCCH, and does not need to retransmit for the terminal whose feedback information is ACK. It should be noted here that because the number of PDFCH channels is large (such as 5184) and the probability that the feedback information of each terminal is NACK is less than 0.1, the probability of this special situation occurring is small.
- Step 13 the base station generates a PDFCH signal of the target terminal
- the specific process includes:
- Step 1302 performing binary phase shift keying (BPSK) modulation
- Step 1307 Map the spread sequence to symbols from symbol i to symbol i+sequence length according to the starting symbol i;
- Step 1309 If the feedback information of multiple terminals needs to be sent on the same PDFCH resource, The signals of multiple terminals are multiplexed together;
- Step 1310 Use a unified DL HARQ-RNTI to scramble the multiplexed signal
- Step 1311 Send the scrambled signal.
- CS sequence is generated by cyclic shift of the base sequence
- the base sequence is a

- s represents the time slot number
- c represents the PDFCH channel opportunity number within the time sequence
- p represents the PRB label number
- the cyclic shift sequence is:
- ⁇ q represents the cyclic shift coefficient
- the time domain orthogonal sequence is:
- the base sequence of the time domain orthogonal sequence is shown in Table 2.
- the base sequence of can be derived according to the rules.
- z represents the PDFCH signal sent on the nth subcarrier of the pth resource block in the mth symbol
- dk represents the data on IQ
- the terminal-side process includes:
- Step 14 The terminal receives resource configuration information sent by the base station
- the terminal obtains the PDFCH resources configured (or scheduled) by the base station through the pdfch-ResourceCommon signaling transmitted by the MIB or SIB.
- Step 15 The terminal determines a first resource for transmitting feedback information of uplink data according to the meta bit
- the base station sends HARQ ACK/NACK information to the detected terminal, solving the energy waste problem caused by blind detection of PDCCH on the terminal side.
- the terminal first detects at its own HARQ ACK/NACK information resource location. If it is NACK and PUSCH retransmission is required, the terminal will continue to blindly detect PDCCH and perform the prescribed subsequent processing flow, thereby saving terminal power consumption.

本公开涉及通信技术领域,特别涉及一种信息传输方法、装置、终端及网络设备。
非协调随机接入和传输技术,是随机接入技术和多址传输技术的融合升级,不再把初始接入和数据传输作为两个独立的过程,而是融合成一个过程,以支持巨量终端的接入和传输、降低时延、提高接入和传输的成功率。
针对非协调非正交多址接入技术,网络设备(例如基站(the next Generation Node B,gNB))和用户设备(User Equipment,UE)之间除了主信息块(Master Information Block,MIB)、系统信息块(System Information Block,SIB)等协调信息外,没有UE专用(specific)的协调信息,甚至没有分配的物理层UE标识(Identifier,ID)(如小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)),这会导致gNB无法为UE分配混合自动重传请求应答(Hybrid automatic repeat request acknowledgement,HARQ ACK)信道资源、无法保证上行数据(例如,物理上行链路共享信道(Physical uplink shared channel,PUSCH))的反馈信息的准确传输。

首先,基于本公开提供的技术方案,对可能涉及的部分技术术语进行介绍。
非协调非正交多址接入技术背景
UE侧非协调非正交多址接入技术(URAT)方案的处理过程:
(1)由待发送数据的信息比特(包括UE ID)产生元比特(也可以称为元数据比特),具体的,可以把信息比特的循环冗余校验(Cyclic Redundancy Check,CRC)作为元比特。
需要说明的是,元比特为对待发送数据的信息比特进行编码生成的比特流,比如,一种编码方式为CRC编码,待发送数据的信息通过CRC编码器后生成的比特流为16比特的比特流,另一种编码方式为取待发送数据的信息的前X个比特,即待发送数据的信息通过该CRC编码器后生成的比特流为X比特的比特流。
(2)元数据比特经过指数调制(index modulation)后由前导码(Preamble)承载,传输的Preamble同时用于实现随机接入。
(3)信息比特经过极低速率编码(extremely low rate coding)和多用户编码(multi-user coding)后由类似PUSCH的信道承载,其中,extremely low rate coding用来实现非正交多址传输,multi-user coding是用来进一步增加不同UE编码码字之间的距离,从而提高多址传输的性能。
随机接入和多址传输的融合,一是用于随机接入的Preamble信号和多址传输的数据信号复用在一起进行传输,二是Preamble上所携带的元数据比特用来控制multi-user coding,包括加扰、交织、重复传输图样、冗余版本(Redundancy Version,RV)、资源映射、包分多址接入(Packet Division Multiple Access,PDMA)扩频序列、功率等。
本公开实施例提供了一种信息传输方法、装置、终端及网络设备,以保证非协调非正交多址接入中上行数据的反馈信息的准确传输。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原
理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图2所示,本公开实施例提供一种信息传输方法,由终端执行,包括:
步骤S201,根据上行数据对应的元比特,确定传输资源;
需要说明的是,该传输资源指的是用于传输所述上行数据对应的反馈信息的资源。
在一些实施例中,所述元比特为基于对所述上行数据进行编码生成的比特流;例如,一种编码方式为CRC编码,上行数据通过CRC编码器后生成的比特流为16比特的比特流;另一种编码方式为取上行数据的前X个比特,即上行数据通过CRC编码器后生成的比特流为X比特的比特流。
在一些实施例中,该元比特可以用于指示上行数据的编码方式、交织方式、加扰方式等。
这里需要说明的是,终端的上行数据对应的元比特可以用于区分不同的终端,基于该元比特便能够确定到与终端对应的传输资源,例如,通过元比特可以确定具体的传输资源的索引,基于该索引便能找到特定的传输资源。
步骤S202,在所述传输资源上,检测网络设备发送的所述上行数据的反馈信息;
在一些实施例中,终端可以基于该传输资源对应的正交序列、循环移位与该传输资源上的接收信号进行运算,获取上行数据的反馈信息。
需要说明的是,本公开实施例中通过利用元比特确定传输资源,该元比特是与终端对应的,能够为终端确定唯一的传输反馈信息的传输资源,以此使得终端能够准确确定传输上行数据的反馈信息的资源,保证非协调非正交多址接入中上行数据的反馈信息的准确传输。
在一些实施例中,本公开实施例中所提到的上行数据指的是终端发送给网络设备的数据,其可以是通过PUSCH传输的数据。
在一些实施例中,一种实现方式下,在所述根据上行数据对应的元比特,确定传输资源之前,所述方法还包括:
接收所述网络设备发送的资源配置信息,所述资源配置信息用于指示至少一个传输资源以及每个传输资源对应的标识;
所述资源配置信息包括以下至少一项:时隙数量、每时隙内的资源数量、时域符号资源位置、频域资源位置、正交序列集合。
需要说明的是,该时隙数量指的是至少一个传输资源所占用的时隙的个数;每时隙内的资源数量指的是每个时隙内存在的传输资源的传输机会的个数;时域符号资源位置指的是每个传输资源所占用的时域符号,在一些实施例中,该时域符号资源位置包括:每个传输资源的起始符号的位置以及每个传输资源占用的符号的个数;频域资源位置指的是至少一个传输资源所占用的物理资源块(Physical Resource Block,PRB),在一些实施例中,该频域资源位置包括:起始PRB的标号以及占用的PRB的个数;正交序列集合用于指示至少一个传输资源所对应的正交序列信息,该正交序列集合可以包括时域上正交序列的个数、每PRB上初始循环移位(cyclic shift)的取值以及每PRB上cyclic shift的数量。
需要说明的是,终端通过资源配置信息便可以知道网络设备具体配置的传输资源的总个数。因传输资源的位置是与I、Q信号、时域、频域相关的,则网络设备在进行资源配置时,基于资源的标识从小到大的顺序,先基于I、Q排序,然后频域排序,最后时域排序,便可将每个标识对应的传输资源进行关联。
在一些实施例中,该传输资源可以为物理下行反馈信道(physical downlink feedback channel,PDFCH)资源。
需要说明的是,每一个传输资源均对应一个标识(即资源标识);在一些实施例中,该标识可以为资源的编号或索引(index)。
此处可以理解为,网络设备为终端配置至少一个用于传输所述上行数据对应的反馈信息的传输资源,终端需要基于元比特从这些传输资源中确定实际需要检测的一个或多个传输资源。
在一些实施例中,一种实现方式下,所述根据上行数据对应的元比特,确定传输资源,包括:
根据所述上行数据对应的元比特,确定目标标识;
将与所述目标标识对应的资源确定为传输资源。
在一些实施例中,所述根据所述上行数据对应的元比特,确定目标标识,包括以下实现方式中的一项:
实现方式一、利用所述元比特对所述网络设备配置的传输资源的总个数进行取模运算,获取目标标识;
需要说明的是,本公开实施例中可以通过对元比特的运算,确定一个目标标识,该目标标识与传输资源的标识对应,用于指示唯一的一个传输资源。
实现方式二、将所述元比特输入预设编码器,将输出结果确定为目标标识;
需要说明的是,该预设编码器所输出的比特个数应大于或等于目标比特数,该目标比特数为能够表示网络设备配置的传输资源的总个数的最小比特个数。优选地,预设编码器所输出的比特个数应等于目标比特数。
例如,当网络设备配置了总共256个反馈信息的传输资源,标号为0~255,终端发送的上行数据对应的元比特的长度为16比特,将16比特输入到编码器,编码器输出8比特,编码器的实现方式为输入的第1比特和第2比特进行异或操作得到输出的第1比特,输入的第3比特和第4比特进行异或操作得到输出的第2比特,……,输入的第15比特和第16比特进行异或操作得到输出的第8比特,得到8比特输出结果对应的index为0~255中的一个,即为传输资源对应标识。
这里需要说明的是,因网络设备需要利用传输资源进行反馈信息的发送,二者对资源的理解应该是一致的,故网络设备侧应采用与终端侧一致的实现方式进行目标标识的获取。
需要说明的是,网络设备能够进行传输资源确定的前提是网络设备检测到了终端发送的元比特,若网络设备未检测到终端发送的元比特,则网络设备不会执行后续的确定传输资源的过程。
在一些实施例中,网络设备在确定发送反馈信息的传输资源后,需要通过所述传输资源,向终端发送所述上行数据的反馈信息。
这里需要说明的是,因网络设备侧可能会同时接收到多个终端的上行数据,此时便需要分别确定多个终端分别对应的传输上行数据对应的反馈信息的资源,一种情况下,网络设备最终确定的传输资源与至少两个终端对应,也就是说,网络设备需要在传输资源上同时向至少两个终端发送反馈信息,在一些实施例中,此种情况下,通过所述传输资源,向终端发送所述上行数据的反馈信息的具体实现包括以下至少一项:
A11、若确定所述至少两个终端中存在至少一个终端的上行数据未正确接收,通过所述传输资源,向所述至少两个终端发送所述上行数据的反馈信息,所述反馈信息用于指示网络设备未正确接收所述上行数据;
也就是说,此种情况下,只要有一个终端的上行数据未正确接收,则网络设备就需要在传输资源上向所有终端发送非应答(NACK),即指示网络设备未
正确接收所述上行数据。
A12、若确定所述至少两个终端中存在至少一个终端的上行数据正确接收,通过所述传输资源,向所述至少两个终端发送所述上行数据的反馈信息,所述反馈信息用于指示网络设备正确接收所述上行数据;
也就是说,此种情况下,只要有一个终端的上行数据正确接收,则网络设备就需要在传输资源上向所有终端发送应答(ACK),即指示网络设备正确接收所述上行数据。
还需要说明的是,在上述两种情况下,对于每个终端来说,若网络设备正确接收了该终端的上行数据,则网络设备无需对该终端进行调度重传;若网络设备未正确接收该终端的上行数据,若配置了重传模式,则网络设备可以对该终端进行调度重传,或者,若未配置重传模式,则网络设备也可以不对该终端进行调度重传。若网络设备需要进行调度重传,则需要向所述终端发送下行控制信息,所述下行控制信息用于调度所述终端进行所述上行数据的重传,在一些实施例中,该下行控制信息可以利用所述元比特加扰。
进一步需要说明的是,若终端在所述传输资源上检测网络设备发送的所述上行数据的反馈信息之后,若所述反馈信息指示所述网络设备未正确接收所述上行数据,利用所述元比特检测网络设备发送的下行控制信息。终端基于下行控制信息的检测结果,在合适的位置进行上行数据的重传。
在一些实施例中,该下行控制信息通过物理下行控制信道(Physical downlink control channel,PDCCH)发送。
需要说明的是,已有技术中物理混合自动重传请求指示信道(Physical Hybrid automatic repeat request Indicator Channel,PHICH)用于对上行数据(例如,PUSCH)传输的数据反馈应答(ACK)或非应答(NACK),UE需要先进行PDCCH的盲检,在没有检测到PDCCH后,继续在特定资源上检测PHICH,此种PDCCH盲检会造成严重的UE能量浪费问题,而本公开实施例的此种实现方式通过直接基于元比特确定传输上行数据对应的反馈信息的传输资源,然后直接检测该传输资源上的反馈信息,只有在反馈信息指示网络设备未正确接收所述上行数据的情况下,才进行PDCCH的检测,以此取消了反馈信息之前盲检测PDCCH的过程,可以降低终端功耗,实现终端节能。
下面以终端与基站通信为例,对本公开实施例的具体实现进行举例说明如
下。
以终端与基站通信、且终端发送PUSCH,基站通过PDFCH资源发送反馈信息为例,本公开实施例的具体实现过程如下。
基站侧流程包括:
步骤11、基站向终端发送资源配置信息;
在一些实施例中,基站可以通过MIB或SIB传输PDFCH公共资源(pdfch-ResourceCommon)信令为上行数据的反馈信息配置(或调度)足够的PDFCH资源。
具体地,pdfch-ResourceCommon信令包含以下至少一个参数:
表示每个PDFCH资源起始符号的位置(startingSymbolIndex);
表示每个PDFCH资源占用符号的个数(nrofSymbols);
表示时域上正交序列的个数(nrofSquences),通常等于
表示时域上每时隙(slot)内PDFCH机会的数量(nrofOccationPerSlot);
表示PDFCH资源占用slot的个数(nrofSlots);
表示PDFCH资源起始PRB的标号(startingPRB);
表示PDFCH资源占用PRB的个数(nrofPRBs);
表示每个PRB上初始cyclic shift的取值(startingCSPerPRB);
表示每个PRB上cyclic shift的数量(nrofCSPerPRB)。
通过分别调制I、Q信号,在每个PRB、每个slot的时频域资源上,最多可以容纳个PDFCH,即为基站配置的PDFCH资源的总个数,表示PDFCH的总数。根据PDFCH资源的index,首先进行I、Q排序,然后频域排序,最后时域排序以此确定最终的PDFCH资源的位置。比如,
index=0的PDFCH资源为slot=0、Occ=0、从到的OFDM符号、sequence=0、CS=0、I路;index=577的PDFCH资源为slot=0、Occ=1、从到的OFDM符号、sequence=0、CS=0、Q路。
步骤12、基站根据接收的终端发送的元比特,确定传输所述终端的上行数据的反馈信息的第一资源;
首先通过公式一、确定PDFCH资源的index;
其中,表示PDFCH资源的index,CRC bits表示元比特。
进一步基于该index,确定出发送该终端的反馈信息的PDFCH资源的位置,包括slot=s、Occ=c、起始符号i、squence=j、PRB=p、CS=q、IQ=k。
比如,根据index=577,可以得出s=0、c=1、j=0、q=0、k=1。
需要说明的是,这里可能会出现一个特殊情况,即多个终端的CRC比特经过运算后得到相同的并且有的终端对应的反馈信息为ACK、有的终端对应的反馈信息为NACK,一种情况下,基站在该资源位置上发送NACK,或者,另一种情况下,基站在该资源位置上发送ACK。进一步,当配置了重传模式,则基站通过PDCCH为反馈信息为NACK的终端进行重传,不需要为反馈信息为ACK的终端进行重传。这里需要说明的是,因为PDFCH信道数量较大(如5184)、每个终端的反馈信息为NACK的概率小于0.1,所以这种特殊情况出现的概率较小。
步骤13、基站产生目标终端的PDFCH信号;
具体过程包括:
步骤1301、根据终端的PUSCH检测结果,产生ACK比特(=0)或NACK比特(=1);
步骤1302、进行二进制相移键控(Binary Phase Shift Keying,BPSK)调制;
步骤1303、根据IQ=k,选择I路或Q路;
步骤1304、根据CS=q,对基序列进行循环移位q,得到循环移位(Cyclic Shift,CS)序列;
步骤1305、根据PRB=p,将CS序列映射到PRB p的12个资源元素(Resource Element,RE)上;
步骤1306、根据sequence=j,将PRB p上12个RE的数据进行分别扩频;
步骤1307、根据起始符号i,将扩频后序列映射到符号i到符号i+sequence长度的符号上;
步骤1308、根据slot=s、Occ=c,将上述信号映射到第s个slot的第c个机会上;
步骤1309、若在同一PDFCH资源上需要发送多个终端的反馈信息,则将
多个终端的信号复用在一起;
步骤1310、使用统一的DL HARQ-RNTI,对复用信号进行加扰;
步骤1311、发送加扰后的信号。
需要说明的是,CS序列由基序列通过循环移位生成;
其中,基序列为
其中,表示产生基序列的原始序列,其定义如表1所示;j表示-1的平方根的复数形式。
表1原始序列
参数u表示基序列的序号,
其中,s表示时隙序号,c表示时序内PDFCH信道机会序号,p表示PRB标号序号。
循环移位的序列为:
其中,表示每个资源块内子载波的数量,αq表示循环移位系数,
时域正交序列为:
其中,表示时域正交序列的基序列,由表2所示,的基序列可以按规律得出。
表2时域正交序列的基序列
其中,
在某终端的PDFCH信道资源上(slot=s、Occ=c、squence=j、PRB=p、CS=q、IQ=k),实际上是个RE的资源块,发送PDFCH信号,在该资源块的第m个符号、第n个子载波上发送的PDFCH信号通过如下公式表示:
其中,z表示在第m个符号、第p个资源块的第n个子载波上发送的PDFCH信号,dk表示IQ上的数据,k=0表示I路上的数据d0,k=1表示Q路上的数据d1。
终端侧流程包括:
步骤14、终端接收基站发送的资源配置信息;
在一些实施例中,终端通过MIB或SIB传输的pdfch-ResourceCommon信令,获取基站配置(或调度)的PDFCH资源。
步骤15、终端根据元比特,确定传输上行数据的反馈信息的第一资源;
首先通过公式确定PDFCH资源的index
进一步,基于该index,确定出PDFCH资源的位置,包括slot=s、Occ=c、
PRB=p、squence=j、CS=q、IQ=k。
步骤16、终端使用squence=j、CS=q与上述资源位置上的接收信号进行相关运算,得到反馈信息比特d。
综上可知,本公开实施例能够达到如下有益效果:
解决了终端能量浪费的问题:在海量接入场景下,通过基站向检测出的终端发送HARQ ACK/NACK信息,解决了终端侧盲检PDCCH所带来的能量浪费问题。终端首先在自己的HARQ ACK/NACK信息资源位置上检测,如果为NACK时、并且需要进行PUSCH重传时,终端将继续盲检PDCCH,并进行规定的后续处理流程,以此能够节省终端功耗。
解决了非协调非正交技术中的UE ID问题:针对非协调非正交多址接入技术,基站和终端之间除了MIB、SIB等协调信息外,没有物理层UE ID信息,将使用发送PUSCH对应的元比特运算后的取值,即index,作为终端暂时的ID,用来进行发送反馈信息的资源的确定,以此能够保证PUSCH的反馈信息的准确发送。

步骤S302,通过所述传输资源,向终端发送所述上行数据的反馈信息。
需要说明的是,本公开实施例中通过利用元比特确定传输资源,该元比特是与终端对应的,能够为终端确定唯一的传输反馈信息的传输资源,以此使得网络设备能够准确确定传输上行数据的反馈信息的资源,保证非协调非正交多址接入中上行数据的反馈信息的准确传输。
