- a UE that only supports non-coherent capabilities cannot use codewords with partial coherent and full coherent capabilities.
- UEs that support partial coherent and non-coherent capabilities cannot use codewords with full coherent capabilities.
- Table 2 UEs with non-coherent capabilities can only use TPMI 0 to 3, and UEs with some coherent capabilities (which can be backward compatible to support non-coherent capabilities) can use TPMI 0 to 11.
- Full coherent capabilities (which can support backward Partial and non-coherent capabilities) UEs can use all codewords.
- the maximum transmit power of each antenna port is limited to one part of the maximum number of antenna ports. For example, when a maximum of 4 antenna ports are supported, the maximum power of each antenna port is limited to 1/4 of the maximum transmit power of the UE.
- the maximum antenna port supported is 4, for a UE with incoherent capability, only one antenna port can be selected for transmission by antenna selection, and the maximum transmission power of the antenna port is 1/4 of the maximum power allowed by the UE.

- a first set of extended codewords is required
- the antenna ports or antenna port groups corresponding to the codewords are sent and transmitted on different frequency domain resources respectively, that is, the antenna ports used to transmit the N frequency domain resource sets are selected. That is, the two antenna ports only send transmissions on one set of frequency domain resources, instead of both antenna ports transmitting the same frequency domain resources. Therefore, the UE first divides the scheduling resources into N frequency domain resource sets according to the scheduling indication information sent by the base station and/or the allocation mode predetermined with the base station. However, according to the antenna ports or antenna port groups corresponding to the codewords of the first spreading codeword set, resource transmission is realized on the N frequency domain resource sets.
- the UE supports 2 antenna ports with non-coherent capabilities.
- the codeword is According to the method described in FIG. 2, because the antenna ports are incoherent, the phase between the antenna ports is uncontrollable, and there will be unpredictable interference between the antenna ports. Therefore, the resources scheduled by the base station are divided into two frequency domain resource sets in the frequency domain, and the two antenna ports respectively only send transmissions on one frequency domain resource set. In this way, there is no mutual interference between multiple ports.

For example, if in the case of non-uniform division, the scheduling resource with 4 RB resources can be divided into a resource set of ⁇ #0 ⁇ and a resource set of ⁇ #1, #2, #3 ⁇ . If the transmission performance of antenna port 0 is better than that of antenna port 1, then when the UE allocates antenna ports, the UE uses the code word with TPMI 0 The determined antenna port 0 for transmission has resource sets of #1, #2, and #3.

For example, a user equipment that supports a maximum of 2 antennas can only use half of the maximum power of the user equipment if only one antenna is used to send information. With the development of technology, the device performance of wireless communication equipment has been improving and the cost is decreasing. Therefore, the next-generation mobile communication system is likely to be equipped with multiple high-performance antennas, which also provides the possibility to optimize the maximum power limit.
NR***的上行MIMO传输分为两种:基于码本(codebook based)的传输和非基于码本(non codebook based)的传输。对非基于码本的传输,相关技术已经能支持其利用到最大功率。对于基于码本的传输,相关技术还没有明确的方案支持其利用到最大功率。The uplink MIMO transmission of the NR system is divided into two types: codebook-based transmission and non-codebook-based transmission. For non-codebook-based transmission, related technologies have been able to support the use of maximum power. For codebook-based transmission, there is no clear solution in related technologies to support the use of maximum power.

(4)根据所述波束信息所指示的波束发送所述频域资源集合承载的所述上行传输。(4) Send the uplink transmission carried by the set of frequency domain resources according to the beam indicated by the beam information.
例如,用天线端口0发送频域资源集合0承载的上行传输。用天线面板0发送频域资源集合0承载的上行传输。用波束0发送频域资源集合0承载的上行传输。用传输链0发送频域资源集合0承载的上行传输。For example, antenna port 0 is used to send uplink transmission carried by frequency domain resource set 0. Antenna panel 0 is used to transmit the uplink transmission carried by frequency domain resource set 0. Use beam 0 to send uplink transmission carried by frequency domain resource set 0. Use transmission chain 0 to send the uplink transmission carried by frequency domain resource set 0.

具体而言,预编码码字即为一个矩阵,矩阵的行与天线端口对应,矩阵的列与层对应。如果预编码码字的某一行的矩阵元素都是0,则预编码码字的这一行对应的天线端口是零功率的天线端口。如果预编码码字的某一行的矩阵元素不全都是0,则预编码码字的这一行对应的天线端口是非零功率的天线端口。Specifically, the precoding codeword is a matrix, the rows of the matrix correspond to antenna ports, and the columns of the matrix correspond to layers.

If the matrix elements of a certain row of the precoding codeword are not all 0, the antenna port corresponding to this row of the precoding codeword is a non-zero power antenna port.

(7)根据所述参考信号信息相同的传输参数发送所述频域资源集合承载的所述上行传输。(7) Send the uplink transmission carried by the set of frequency domain resources according to the same transmission parameters of the reference signal information.
例如,在波束管理过程中,基站调度UE使用不同的传输参数,如不同的波束,或不同参数的发送滤波器发送不同的SRS,假设一共发送了3个SRS,分别用SRI 0,SRI 1,SRI 2标识。当基站调度SRI 0和SRI 1发送上行传输时,UE将调度信息指示的资源分为N=2个频域资源集合,用发送SRI 0的传输参数或发送滤波器发送第一个频域资源集合;用发送SRI 1的传输参数或发送滤波器发送第二个频域资源集合。For example, in the beam management process, the base station schedules the UE to use different transmission parameters, such as different beams, or transmission filters with different parameters to send different SRSs. Assuming that a total of 3 SRSs are sent, SRI 0, SRI 1, respectively, SRI 2 logo. When the base station schedules SRI 0 and SRI 1 to send uplink transmissions, the UE divides the resources indicated by the scheduling information into N=2 frequency domain resource sets, and sends the first frequency domain resource set with the transmission parameters of SRI 0 or the transmission filter. ; Send the second set of frequency domain resources by sending the transmission parameters of SRI 1 or the sending filter.
具体而言,根据上行传输的调度信息包含的SRI域对应的SRS资源或SRS资源集合中包含的天线端口数,确定空域资源信息的个数M。Specifically, the number M of spatial resource information is determined according to the SRS resource corresponding to the SRI field included in the scheduling information of uplink transmission or the number of antenna ports included in the SRS resource set.
例如,上行传输PUSCH的调度信息包含的SRI域对应的SRS资源中指示SRS端口数为4,则空域资源信息的个数M=4。当空域资源信息表示天线端口时,PUSCH的天线端口数为4。For example, if the SRS resource corresponding to the SRI field included in the scheduling information of the uplink transmission PUSCH indicates the number of SRS ports is 4, then the number of spatial resource information M=4. When the spatial resource information indicates antenna ports, the number of antenna ports of the PUSCH is 4.
具体而言,根据上行传输的调度信息包含的SRI域对应的SRS资源或SRS资源集合中包含的天线端口数,以及上行传输的调度信息中的预编码信息,确定空域资源信息的个数M。Specifically, the number M of spatial resource information is determined according to the SRS resource corresponding to the SRI field included in the uplink transmission scheduling information or the number of antenna ports included in the SRS resource set, and the precoding information in the uplink transmission scheduling information.
根据所述上行传输的调度信息中的以下至少之一的内容确定空域资源信息的个数M:SRI域对应的测量参考信号SRS资源中包含的天线端口数量;SRI域对应的测量参考信号SRS资源集合中包含的天线端口数量;预编码信息;天线端口的相干能力。Determine the number of spatial resource information M according to at least one of the following content in the scheduling information of the uplink transmission: the number of antenna ports included in the measurement reference signal SRS resource corresponding to the SRI domain; the measurement reference signal SRS resource corresponding to the SRI domain The number of antenna ports included in the set; precoding information; the coherence capability of the antenna ports.
上行传输的调度信息中的预编码信息包括以下指示之一:TPMI,层数。The precoding information in the scheduling information for uplink transmission includes one of the following indications: TPMI, the number of layers.
具体而言,根据上行传输的调度信息包含的SRI域对应的SRS资源或SRS资源集合中包含的天线端口数以及上行传输的调度信息中的预编码信息,确定上行传输的预编码矩阵。根据上行传输的预编码矩阵确定空域资源信息的个数M,M等于矩阵中的非零功率的行数。Specifically, the precoding matrix for uplink transmission is determined according to the SRS resource corresponding to the SRI field or the number of antenna ports included in the SRS resource set included in the scheduling information for uplink transmission and the precoding information in the scheduling information for uplink transmission. The number M of spatial resource information is determined according to the precoding matrix of uplink transmission, where M is equal to the number of rows of non-zero power in the matrix.
如果预编码码字的某一行的矩阵元素都是0,则预编码码字的这一行对应的天线端口是零功率的行。如果预编码码字的某一行的矩阵元素不全都是0,则预 编码码字的这一行对应的天线端口是非零功率的行。If the matrix elements of a certain row of the precoding codeword are all 0, the antenna port corresponding to this row of the precoding codeword is a zero-power row. If the matrix elements of a certain row of the precoding codeword are not all 0, the antenna port corresponding to this row of the precoding codeword is a row with non-zero power.
具体而言,在无线通信***中,信号在传播过程中会随着距离增大而衰减。用户设备的最大发送功率决定其通信范围。最大发送功率越高,其信号可以传播的距离越远。因此,通信***会对用户设备的最大发送功率进行规定。例如,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)的长期演进(Long Term Evolution,LTE)***中,UE一般需要支持功率等级(power class)3,即23dBm。另外,有些UE还支持功率等级2,即26dBm。Specifically, in a wireless communication system, the signal attenuates as the distance increases during propagation. The maximum transmission power of the user equipment determines its communication range. The higher the maximum transmit power, the farther the signal can travel. Therefore, the communication system regulates the maximum transmission power of the user equipment. For example, in the Long Term Evolution (LTE) system of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP), the UE generally needs to support power class 3, that is, 23 dBm. In addition, some UEs also support power level 2, which is 26dBm.
UE可以配置1个或多个天线端口(antenna port)。每个天线端口对应一个或多个天线链路(antenna chain)或射频(RF chain),每个天线端口或天线链路对应一个PA(power amplifier,功率放大器)。为描述简单,假设每个天线端口对应一个PA。如果天线端口对应多个PA,则多个PA的功率合起来是这个天线端口的功率能力。The UE can be configured with one or more antenna ports (antenna ports). Each antenna port corresponds to one or more antenna links (antenna chain) or radio frequency (RF chain), and each antenna port or antenna link corresponds to a PA (power amplifier, power amplifier). For simplicity of description, it is assumed that each antenna port corresponds to a PA. If the antenna port corresponds to multiple PAs, the power of the multiple PAs combined is the power capability of this antenna port.
对于支持多个天线端口的UE,为满足特定的功率等级,可能每个天线端口或者部分天线端口能达到功率等级要求的功率,也可能所有天线端口都不能达到功率等级要求的功率,但是部分或全部天线端口组合起来能达到功率等级要求的功率。例如,对支持2天线端口的UE,在支持功率等级3时,需要达到最大发送功率为23dBm。2根天线端口支持的功率可能是以下之一:23dBm+23dBm;23dBm+20dBm;或20dBm+20dBm。For UEs that support multiple antenna ports, in order to meet a specific power level, each antenna port or some antenna ports may reach the power required by the power level, or all antenna ports may not reach the power required by the power level, but some or The combination of all antenna ports can reach the power required by the power level. For example, for a UE that supports 2 antenna ports, when supporting power level 3, the maximum transmission power needs to be 23 dBm. The power supported by the two antenna ports may be one of the following: 23dBm+23dBm; 23dBm+20dBm; or 20dBm+20dBm.
当所有的天线端口都不能独立达到最大发送功率时,需要多个天线端口组合达到最大发送功率。例如,两个20dBm的天线端口同时发送可以达到23dBm的发送功率。当仅发送多输入多输出(Multiple-Input Multiple-Out-put,MIMO)1层数据时,如果两个天线端口之间有相干能力,则基站可以调度UE用两个天线端口发送,并用不同的码字使得两个天线端口与实际的信道最匹配。天线之间有相干能力(coherent),是指天线之间的相位差是可以控制的。如果两个天线端口之间没有相干能力(non coherent),则一般情况下,基站不能调度UE用两个天线端口发送,因为两个天线端口之间的相位不可控,从而端口之间的干扰不可控。如果使用两个天线端口发送同样的数据,那么天线端口之间的信号可能是正向叠加至两倍功率,也可能是负向叠加,消减至0功率。When all the antenna ports cannot reach the maximum transmission power independently, a combination of multiple antenna ports is required to reach the maximum transmission power. For example, two antenna ports of 20 dBm can transmit at the same time with a transmission power of 23 dBm. When only sending Multiple-Input Multiple-Out-put (MIMO) layer 1 data, if there is coherence between the two antenna ports, the base station can schedule the UE to use two antenna ports to transmit, and use different The codeword makes the two antenna ports best match the actual channel. The coherent capability between the antennas means that the phase difference between the antennas can be controlled. If there is no coherent capability (non-coherent) between two antenna ports, in general, the base station cannot schedule the UE to use two antenna ports to transmit, because the phase between the two antenna ports is uncontrollable, and the interference between the ports is uncontrollable. control. If two antenna ports are used to send the same data, then the signal between the antenna ports may be superimposed in the positive direction to twice the power, or it may be superimposed in the negative direction, and reduced to zero power.
以MIMO多天线方式发送物理上行共享信道(Physical Uplink Shared Channel,PUSCH)传输时,包括两种:基于码本的(codebook based)的传输、非基于码本的(non codebook based)的传输。When the physical uplink shared channel (PUSCH) transmission is sent in the MIMO multi-antenna manner, there are two types: codebook-based transmission and non-codebook-based transmission.
基于码本的传输是指基站从预先定义的码本中选一个码字作为上行传输的预编码。码本是预先定义的一组码字,包括至少一个码字(codeword)。每个码字是一个矩阵,用于发送端多天线端口的预编码。码字矩阵的每行代表一个天线端口(antenna port);每列代表一层(MIMO layer)。例如,表1给出了2个天线端口1层的码本,码本中包括6个码字,每个码字是两行一列。码字用TPMI(Transmitted Precoding Matrix Indicator,传输预编码矩阵指示)标识。Codebook-based transmission means that the base station selects a codeword from a predefined codebook as precoding for uplink transmission. A codebook is a predefined set of codewords, including at least one codeword. Each codeword is a matrix used for precoding of multiple antenna ports at the transmitter. Each row of the codeword matrix represents an antenna port (antenna port); each column represents a layer (MIMO layer). For example, Table 1 shows a codebook with 2 antenna ports and a layer. The codebook includes 6 codewords, and each codeword is two rows and one column. The codeword is identified by TPMI (Transmitted Precoding Matrix Indicator).
一般地,基站根据UE发送天线的能力确定天线端口数,调度UE发送SRS,用于测量上行信道,也叫信道探测。基站根据信道测量结果为后续的上行传输确定MIMO参数,包括层数、预编码等,然后为UE的上行传输指定一个确定的预编码矩阵,即TPMI。UE使用指定的预编码矩阵对所传输的数据进行预编码,发送给基站。Generally, the base station determines the number of antenna ports according to the UE's ability to transmit antennas, and schedules the UE to transmit SRS, which is used to measure the uplink channel, also called channel sounding. The base station determines the MIMO parameters for subsequent uplink transmissions according to the channel measurement results, including the number of layers, precoding, etc., and then specifies a certain precoding matrix, namely TPMI, for the uplink transmission of the UE. The UE uses the designated precoding matrix to precode the transmitted data and send it to the base station.
基站可能为UE配置不同的SRS资源,UE在不同的SRS资源上发送不同的SRS,那么基站还需要为上行传输指示SRS资源(SRI,SRS resource indication)。例如,不同SRS资源对应不同的发送波束资源(组),不同的天线面板(panel)(组),或是对应不同的天线端口的预编码方式。The base station may configure different SRS resources for the UE, and the UE transmits different SRS on different SRS resources, then the base station also needs to indicate SRS resource (SRI, SRS resource indication) for uplink transmission. For example, different SRS resources correspond to different transmit beam resources (groups), different antenna panels (groups), or precoding methods corresponding to different antenna ports.
对于非基于码本的传输,基站不需要指示TPMI给UE,但是如果UE使用了多天线端口,UE可以自己确定传输的预编码信息。For non-codebook-based transmission, the base station does not need to instruct the TPMI to the UE, but if the UE uses multiple antenna ports, the UE can determine the precoding information for transmission by itself.
表1Table 1
当UE配置多个天线端口时,按照天线端口之间的调整所传输信号的相位差的能力分为不同的相干(coherent)能力:全相干(full coherent)、部分相干(partial coherent)以及非相干(non coherent)。高级别的相干能力的UE向下支持。全相干能力高于部分相干能力,部分相干能力高于非相干能力。When the UE is configured with multiple antenna ports, according to the ability to adjust the phase difference of the transmitted signal between the antenna ports, it is divided into different coherent capabilities: full coherent, partial coherent and non-coherent (non coherent). High-level coherent capability UE downward support. Full coherence ability is higher than partial coherence ability, and partial coherence ability is higher than non-coherent ability.
非相干(Non Coherent)能力表示天线端口之间不能精确调整相位差;部分相干(partial coherent)能力表示仅部分天线端口之间能精确调整相位差,全相 干(full coherent)能力表示所有天线端口之间能精确调整相位差。Non-coherent capability means that the phase difference between antenna ports cannot be accurately adjusted; partial coherent capability means that only part of the antenna ports can accurately adjust the phase difference, and full coherent capability means that the phase difference between all antenna ports The phase difference can be accurately adjusted between.
非相干能力的UE仅可以支持为非相干能力的UE设计的码字;部分相干能力的UE可以支持为非相干能力的UE设计的码字以及为部分相干能力的UE设计的码字;全相干能力的UE可以支持为非相干能力的UE设计的码字、为部分相干能力的UE设计的码字以及为全相干能力的UE设计的码字。Non-coherent UEs can only support codewords designed for non-coherent UEs; partially coherent UEs can support codewords designed for non-coherent UEs and codewords designed for partially coherent UEs; fully coherent A capable UE can support codewords designed for UEs with non-coherent capabilities, codewords designed for UEs with partial coherence capabilities, and codewords designed for UEs with full coherence capabilities.
例如,全相干能力的UE也可以支持部分相干和非相干的传输。部分相干的UE也支持非相干的传输。如表1所示的2天线端口1层的码本,TPMI 0和1的矩阵中都各有一个天线端口为0,即只用于一个天线端口发送,也叫天线端口选择,或者简称天线口选择,或者天线选择。TPMI 0和TPMI 1是为非相干能力的UE设计的。TPMI 2到TPMI 5是两个天线端口都使用,天线端口之间相位不同。TPMI 2到TPMI 5这几个码字原本是为全相干能力的UE设计的。2天线端口只有全相干和非相干之分。For example, a fully coherent capable UE may also support partially coherent and non-coherent transmission. Partially coherent UEs also support non-coherent transmission. As shown in Table 1 for the 2-antenna port 1-layer codebook, each of the TPMI 0 and 1 matrix has an antenna port of 0, that is, only one antenna port is used for transmission, also called antenna port selection, or antenna port for short Choice, or antenna choice. TPMI 0 and TPMI 1 are designed for UEs with incoherent capabilities. TPMI 2 to TPMI 5 are used for both antenna ports, and the phases between the antenna ports are different. The codewords TPMI 2 to TPMI 5 were originally designed for UEs with full coherence capabilities. 2 Antenna ports are only divided into fully coherent and non-coherent.
表2是4天线端口1层的码本。4天线端口除了全相干、非相干,还有部分相干。4个元素中只有1个非零元素的码字用于非相干的传输,两个非零元素的码字用于部分相干的传输,四个非零元素的码字用于全相干的传输。在表2所示的码字是用于4个天线端口的,4个天线端口分别记为天线端口0~3。表2中用于部分相干传输的码字,假设天线端口0和2是一组,1和3是另一组,组内的天线端口具有相干能力,即可以控制相位差,而组间不具有相干能力。Table 2 is a codebook for the first layer of 4 antenna ports. In addition to fully coherent and non-coherent, 4 antenna ports are partially coherent. Only one non-zero element codeword among the four elements is used for non-coherent transmission, two non-zero element codewords are used for partially coherent transmission, and four non-zero element codewords are used for fully coherent transmission. The codewords shown in Table 2 are used for 4 antenna ports, and the 4 antenna ports are respectively denoted as antenna ports 0 to 3. The codewords used for partially coherent transmission in Table 2. Assuming that antenna ports 0 and 2 are a group, and 1 and 3 are another group, the antenna ports in the group have coherent capability, that is, the phase difference can be controlled, but there is no Coherence.
表2Table 2
当设备只使用部分天线发送时,最大功率的限制等同于全部天线发送时的最大功率限制,称为满功率(full power,或者full rate)发送。When the device uses only part of the antennas for transmission, the maximum power limit is equivalent to the maximum power limit for all antennas, which is called full power (or full rate) transmission.
对非基于码本的传输,相关技术已经能支持其利用到最大功率,即支持满功率发送。对于基于码本的传输,相关技术仅能支持全相干能力的UE的满功率发送,对于部分相干以及非相干能力的UE不能支持满功率发送。For non-codebook-based transmission, related technologies can already support the use of maximum power, that is, full power transmission. For codebook-based transmission, the related technology can only support full power transmission for UEs with full coherence capability, and cannot support full power transmission for UEs with partial coherence and non-coherence capabilities.
对部分相干以及非相干能力的UE不支持满功率发送表现在两个方面:The failure to support full power transmission for partially coherent and non-coherent UEs is manifested in two aspects:
不允许UE使用超过自己相干能力的码字。例如,仅支持non coherent能力的UE,不能使用partial coherent、full coherent能力的码字。支持partial coherent和non coherent能力的UE,不能使用full coherent能力的码字。例如,表2中,非相干能力的UE只能使用TPMI 0~3,部分相干能力(可以向下兼容支持非相干能力)的UE可以使用TPMI 0~11,全相干能力(可以向下兼容支持部分和非相干能力)的UE可以使用所***字。The UE is not allowed to use codewords that exceed its own coherence capabilities. For example, a UE that only supports non-coherent capabilities cannot use codewords with partial coherent and full coherent capabilities. UEs that support partial coherent and non-coherent capabilities cannot use codewords with full coherent capabilities. For example, in Table 2, UEs with non-coherent capabilities can only use TPMI 0 to 3, and UEs with some coherent capabilities (which can be backward compatible to support non-coherent capabilities) can use TPMI 0 to 11. Full coherent capabilities (which can support backward Partial and non-coherent capabilities) UEs can use all codewords.
每个天线端口最大的发送功率被限制为最大天线端口数量分之一。例如,当最大支持4天线端口时,每个天线端口被限制最大功率为UE的最大发送功率的1/4。The maximum transmit power of each antenna port is limited to one part of the maximum number of antenna ports. For example, when a maximum of 4 antenna ports are supported, the maximum power of each antenna port is limited to 1/4 of the maximum transmit power of the UE.
即,当支持最大天线端口为4时,对于非相干能力的UE,只能以天线选择的方式选择一个天线端口发送,而该天线端口最大发送功率是1/4的UE允许的最大功率。一个端口的实际发送功率是UE的上行传输的允许功率的1/4。That is, when the maximum antenna port supported is 4, for a UE with incoherent capability, only one antenna port can be selected for transmission by antenna selection, and the maximum transmission power of the antenna port is 1/4 of the maximum power allowed by the UE. The actual transmit power of a port is 1/4 of the allowable power of the UE's uplink transmission.
一般认为,对非相干能力的UE使用全相干能力的码字,由于天线端口之间不能按照要求调整相位,因此天线端口之间的干扰不可控。也就是天线端口之间的相位差是随机的。但是如果只用天线选择的方案,相当于直接损失了3/4的发送功率,这种损失对性能的影响也是很可观的。It is generally believed that if a codeword with a full coherence capability is used for a non-coherent UE, since the phase between antenna ports cannot be adjusted as required, the interference between antenna ports is uncontrollable. That is, the phase difference between the antenna ports is random. However, if only the antenna selection scheme is used, it is equivalent to a direct loss of 3/4 of the transmission power, and this loss has a considerable impact on performance.
因此,智能的***不应该对功率有这样的限制。应该允许non coherent能力的UE,使用partial coherent、full coherent能力的码字,以及partial coherent能力的UE使用full coherent能力的码字。可能存在一种评估方法,当天线端口之间的随机干扰带来的性能损失大于由于天线端口数减少带来的功率减少以导致 的性能损失,则采用天线端口减少的方式,即天线端口选择,或者天线端口组选择;否则,采用非天线端口(组)选择的方式。Therefore, smart systems should not have such restrictions on power. It should allow non-coherent capable UEs to use partial coherent and full coherent capable codewords, and partial coherent capable UEs to use full coherent capable codewords. There may be an evaluation method. When the performance loss caused by random interference between antenna ports is greater than the performance loss caused by the power reduction caused by the reduction in the number of antenna ports, the antenna port reduction method is adopted, that is, the antenna port selection. Or antenna port group selection; otherwise, a non-antenna port (group) selection method is adopted.
这种评估方法包括,根据接收端的性能进行选择使用天线端口(组)选择或者,非天线端口(组)选择。例如,对比天线端口(组)选择的方式与非天线端口(组)选择的方式的接收性能,哪种性能优就选择哪种方式。This evaluation method includes the selection of antenna port (group) selection or non-antenna port (group) selection according to the performance of the receiving end. For example, compare the reception performance of the antenna port (group) selection method and the non-antenna port (group) selection method, and choose which method has the best performance.
非天线端口(组)选择,即允许UE使用超过自己相干能力的码字,包括以下两种方式:Non-antenna port (group) selection, that is, allowing the UE to use codewords that exceed its own coherence capability, including the following two methods:
方式1:多个天线端口都发送传输,天线端口之间存在随机干扰。Method 1: Multiple antenna ports all send transmission, and there is random interference between antenna ports.
方式2:多个天线端口都发送传输,不同天线端口分别在不同的频域资源上承载上行传输。Manner 2: Multiple antenna ports all send transmission, and different antenna ports carry uplink transmission on different frequency domain resources.
为描述方便,将传统码字分为3类:天线端口选择,天线端口组选择,满天线端口。For the convenience of description, traditional codewords are divided into three categories: antenna port selection, antenna port group selection, and full antenna port.
考虑到4天线端口的部分相干能力,更一般的描述为:Taking into account the partial coherence capability of 4 antenna ports, it is more generally described as:
相关技术采用的方式:对于非相干能力的UE,只能用天线端口选择的码字;对于部分相干能力的UE,可以使用天线端口选择以及天线端口组选择的码字;对于全相干能力的UE,可以使用以上3类的码字。Related technologies: For non-coherent UEs, only codewords selected by antenna ports can be used; for UEs with partial coherence capabilities, codewords for antenna port selection and antenna port group selection can be used; for UEs with full coherence capabilities , You can use the above 3 types of codewords.
图2是根据本申请实施例的一种调度资源传输的示意图。如图2所示,UE支持2天线端口,当UE仅支持非相干的能力时,相关技术采用的方式中UE只能选择TPMI为0和1的天线端口选择方式。当选择TPMI为0时,即只能用天线端口0发送,对应图2中的端口(port)#0;当选择TPMI为1时,即只能用天线端口1发送,对应图2中的port#1。Fig. 2 is a schematic diagram of scheduling resource transmission according to an embodiment of the present application. As shown in Figure 2, the UE supports 2 antenna ports. When the UE only supports incoherent capabilities, the UE can only select antenna port selection methods with TPMI of 0 and 1 in the manner adopted by the related technology. When TPMI is selected as 0, only antenna port 0 can be used for transmission, which corresponds to port (port) #0 in Figure 2; when TPMI is selected as 1, only antenna port 1 can be used for transmission, which corresponds to the port in Figure 2. #1.
然而通过这种相关技术采用的方式,显然不能够将UE的发射功率完全使用,例如图2中的情况,则即直接损失了1/2的发送功率。However, through the method adopted by this related technology, it is obvious that the transmission power of the UE cannot be fully used. For example, in the case in FIG. 2, the transmission power of 1/2 is directly lost.
同理,在所述相干能力类型为部分相干能力时,也同样存在类似的问题。Similarly, when the type of coherence capability is partial coherence capability, similar problems also exist.
在所述相干能力类型为非相干能力或部分相干能力时,所述UE根据第一扩展码字集合中的码字的标识信息从天线端口中选取用于传输所述N个频域资源集合的天线端口;其中,所述第一扩展码字集合包括高于所述UE的相干能力的码字。When the type of coherent capability is non-coherent capability or partial coherent capability, the UE selects from the antenna port the one used to transmit the N frequency domain resource sets according to the identification information of the codewords in the first spreading codeword set Antenna port; wherein, the first spreading codeword set includes codewords higher than the coherence capability of the UE.
具体而言,第一扩展码字集合的码字对应的天线端口之间存在随机相位差。Specifically, there is a random phase difference between the antenna ports corresponding to the codewords of the first spreading codeword set.
图3是根据本申请实施例的另一种调度资源传输的示意图。如图3所示,UE支持2天线端口,当UE仅支持非相干的能力时,相关技术采用的方式中UE只能选择TPMI为0和1的天线端口选择方式,如表1所示。利用上述扩展方式1,UE还支持TPMI={2,3,4,5}的码字中的一个或多个。当TPMI={2}时,即码字为
则UE在天线端口0和1上都以相同方式在基站调度的RB资源上发送1层数据,即天线端口0和1之间不额外添加相位差。
Fig. 3 is a schematic diagram of another scheduling resource transmission according to an embodiment of the present application. As shown in Figure 3, the UE supports 2 antenna ports. When the UE only supports incoherent capabilities, the UE can only select antenna port selection methods with TPMI 0 and 1 in the manner adopted by the related technology, as shown in Table 1. Using the aforementioned extension method 1, the UE also supports one or more of the codewords of TPMI={2, 3, 4, 5}. When TPMI={2}, the codeword is Then, the UE sends layer 1 data on the RB resources scheduled by the base station in the same manner on both antenna ports 0 and 1, that is, no additional phase difference is added between antenna ports 0 and 1.
由于天线端口之间是非相干的,因此天线端口之间的相位不可控,实际的码字等效于
其中α为任意相位值,或随机相位值。
Since the antenna ports are incoherent, the phase between the antenna ports is uncontrollable, and the actual codeword is equivalent to Where α is any phase value, or random phase value.
具体而言,高于空域资源信息的空域资源的相干能力对应的预编码码字的指示信息通过如下方式实现:为了避免上述图2和图3中的发射功率损失,需要第一扩展码字集合的码字对应的天线端口或天线端口分组分别在不同的频域资源上发送传输,即选取用于传输所述N个频域资源集合的天线端口。即两个天线端口分别只在一个频域资源集合上发送传输,而不是两个天线端口都传输相同的频域资源。故而UE首先根据基站发送的调度指示信息和/或与所述基站预先确定的分配方式将调度资源划分为N个频域资源集合。然而再根据第一扩展码字集合的码字对应的天线端口或天线端口分组在N个频域资源集合上实现资源的传输。Specifically, the indication information of the precoding codeword corresponding to the coherence capability of the airspace resource higher than the airspace resource information is realized in the following manner: In order to avoid the transmission power loss in FIG. 2 and FIG. 3, a first set of extended codewords is required The antenna ports or antenna port groups corresponding to the codewords are sent and transmitted on different frequency domain resources respectively, that is, the antenna ports used to transmit the N frequency domain resource sets are selected. That is, the two antenna ports only send transmissions on one set of frequency domain resources, instead of both antenna ports transmitting the same frequency domain resources. Therefore, the UE first divides the scheduling resources into N frequency domain resource sets according to the scheduling indication information sent by the base station and/or the allocation mode predetermined with the base station. However, according to the antenna ports or antenna port groups corresponding to the codewords of the first spreading codeword set, resource transmission is realized on the N frequency domain resource sets.
例如,UE支持非相干能力的2天线端口,除了相关技术采用的方式的TPMI为0和1的天线端口选择方式外,如表1所示,利用上述扩展方式1,UE还支持TPMI={2,3,4,5}的码字中的一个或多个。For example, the UE supports 2 antenna ports with non-coherent capabilities. In addition to the antenna port selection method with TPMI of 0 and 1 used in related technologies, as shown in Table 1, using the above extension method 1, the UE also supports TPMI={2 , 3, 4, 5} one or more of the code words.
当TPMI={2}时,即码字为
按照图2所描述的方式,由于天线端口之间是非相干的,因此天线端口之间的相位不可控,那么天线端口之间会存在不可预测的干扰。因此,将基站调度的资源在频域上分为两个频域资源集合,两个天线端口分别只在一个频域资源集合上发送传输。这样,多个端口之间不存在互相的干扰。
When TPMI={2}, the codeword is According to the method described in FIG. 2, because the antenna ports are incoherent, the phase between the antenna ports is uncontrollable, and there will be unpredictable interference between the antenna ports. Therefore, the resources scheduled by the base station are divided into two frequency domain resource sets in the frequency domain, and the two antenna ports respectively only send transmissions on one frequency domain resource set. In this way, there is no mutual interference between multiple ports.
图4是根据本申请实施例的一种基于频域资源集合传输的示意图。如图4所示,在功率受限场景,图4的不同天线端口以频分方式发送传输存在以下优点:相比图2的天线端口选择的方式和图3多个天线端口都强制发送的方式,每个天线端口仅需要发送一半频率的资源,在功率受限时,也即天线端口以最大发送功率发送时,在每个RE上可以发送更高的功率,因此覆盖可以增强。Fig. 4 is a schematic diagram of transmission based on a set of frequency domain resources according to an embodiment of the present application. As shown in Figure 4, in a power-constrained scenario, the different antenna ports of Figure 4 transmit transmission in a frequency division manner with the following advantages: Compared with the method of antenna port selection in Figure 2 and the manner in which multiple antenna ports are forced to transmit in Figure 3 Each antenna port only needs to transmit resources of half the frequency. When the power is limited, that is, when the antenna port transmits with the maximum transmission power, higher power can be transmitted on each RE, so the coverage can be enhanced.
相比图3,多个天线端口都强制发送的方式会导致天线端口间存在不可预知的干扰,图4的方式天线端口间是频分复用的,因此没有干扰问题,能用同样的功率以更好的性能发送传输。Compared with Figure 3, the forced transmission of multiple antenna ports will cause unpredictable interference between antenna ports. The method of Figure 4 is frequency division multiplexing between antenna ports, so there is no interference problem, and the same power can be used to Better performance to send transmission.
对支持4天线端口部分相干能力的UE,4个天线端口分为两组,每组包括2个天线端口。组内的天线端口具有相干能力,因此可以同时发送。例如,组0包括天线端口0和2,组1包括天线端口1和3。For UEs that support partial coherence of 4 antenna ports, the 4 antenna ports are divided into two groups, and each group includes 2 antenna ports. The antenna ports in the group have coherence capabilities, so they can transmit simultaneously. For example, group 0 includes antenna ports 0 and 2, and group 1 includes antenna ports 1 and 3.
例如,基站为支持4天线端口部分相干能力的UE调度了4个RB以1层发送上行传输,并指示超过UE的相干能力的TPMI={12}时,见表2,即码字为
UE将调度的资源4个RB分为2部分,分别在组0的天线端口0和2以及组1的天线端口1和3上发送。
For example, when the base station schedules 4 RBs for a UE that supports partial coherence capabilities of 4 antenna ports to send uplink transmissions at Layer 1, and indicates that TPMI that exceeds the coherence capabilities of the UE={12}, see Table 2, that is, the codeword is The UE divides the 4 RBs of the scheduled resource into 2 parts, and transmits them on antenna ports 0 and 2 of group 0 and antenna ports 1 and 3 of group 1 respectively.
因此确定频域资源分组个数还与相干能力有关。Therefore, determining the number of frequency domain resource groups is also related to the coherence capability.
需要说明的是:在调度的频域资源内,一部分天线端口发送一部分频域资源,是指对应部分的频域资源放置待发送的数据,而其余部分的频域资源不放置待发送数据。例如,图4中的天线端口#0发送RB#0和RB#1,意思是在RB #0和RB#1的位置放置待发送的数据,而在RB#2和RB#3不放置待发送数据。类似的,天线端口#1发送RB#2和RB#3,是指在RB#2和RB#3的位置放置待发送的数据,而在RB#0和RB#1不放置待发送数据。It should be noted that in the scheduled frequency domain resources, a part of the antenna ports transmit part of the frequency domain resources, which means that the corresponding part of the frequency domain resources place the data to be sent, while the remaining part of the frequency domain resources do not place the data to be sent. For example, antenna port # 0 in Figure 4 transmits RB# 0 and RB# 1, which means that the data to be transmitted is placed in the positions of RB # 0 and RB# 1, and the data to be transmitted is not placed in RB# 2 and RB# 3. data. Similarly, the antenna port # 1 transmits RB# 2 and RB# 3, which means that the data to be transmitted is placed in the positions of RB# 2 and RB# 3, and the data to be transmitted is not placed in RB# 0 and RB# 1.
具体而言,用于表示多个符合相干能力的预编码码字的指示信息通过如下方式实现:Specifically, the indication information used to indicate a plurality of precoding codewords complying with the coherence capability is implemented in the following manner:
在表1中的TPMI为6、7没有被使用,可以用于表示多个符合的相干能力的预编码码字的指示信息。如,TPMI={6}表示TPMI为0和1的组合,TPMI为0的码字用于天线端口0,TPMI为1的码字用于天线端口1。The TPMI in Table 1 is 6 and 7 are not used, and can be used to indicate the indication information of multiple precoding codewords with consistent coherence capabilities. For example, TPMI={6} means that TPMI is a combination of 0 and 1, a codeword with TPMI of 0 is used for antenna port 0, and a codeword with TPMI of 1 is used for antenna port 1.
表2中,TPMI=28、29、30、31没有被使用,用于表示多个符合的相干能力的预编码码字的指示信息。如,TPMI={28}表示TPMI为0、1、2、3的组合。TPMI为0的码字用于天线端口0,TPMI为1的码字用于天线端口1,TPMI为2的码字用于天线端口2,TPMI为3的码字用于天线端口3。In Table 2, TPMI=28, 29, 30, and 31 are not used, and are used to indicate the indication information of a plurality of precoding codewords that conform to the coherence capability. For example, TPMI={28} means that TPMI is a combination of 0, 1, 2, 3. The codeword with TPMI of 0 is used for antenna port 0, the codeword with TPMI of 1 is used for antenna port 1, the codeword with TPMI of 2 is used for antenna port 2, and the codeword with TPMI of 3 is used for antenna port 3.
同理,假设在调度资源中存在有8个RB资源,即#0至#7,那么在进行频域资源传输时,UE首先根据自身的能力确定支持非相干能力的4天线端口,然后将这8个RB调度资源划分为4个频域资源集合,例如,具有#0,#4的频域集合,具有#1,#5的频域集合,具有#2,#6的频域集合和具有#3,#7的频域集合。然后通过使用TPMI={28},按照频域集合的顺序或者预设的规则进行相应的端口分配,例如,对于具有#0,#4的频域集合,UE采用TPMI为0的码字
确定的天线端口0进行传输,对于#1,#5的频域集合,UE采用TPMI为1的码字
确定的天线端口1进行传输。对于具有#2,#6的频域集合,UE采用TPMI为2的码字
确定的天线端口2进行传输。而对于具有#3,#7的频域集合, UE采用TPMI为3的码字
确定的天线端口3进行传输。
Similarly, assuming that there are 8 RB resources in the scheduling resources, that is #0 to #7, then when performing frequency domain resource transmission, the UE first determines the 4 antenna ports that support incoherent capabilities according to its own capabilities, and then The 8 RB scheduling resources are divided into 4 frequency domain resource sets, for example, frequency domain sets with #0, #4, frequency domain sets with #1, #5, frequency domain sets with #2, #6, and #3, #7 frequency domain collection. Then by using TPMI={28}, the corresponding port allocation is performed according to the order of the frequency domain set or preset rules, for example, for the frequency domain set with #0, #4, the UE uses the codeword with TPMI of 0 The determined antenna port 0 is used for transmission. For the frequency domain set of #1 and #5, the UE uses the codeword with TPMI of 1 The determined antenna port 1 performs transmission. For frequency domain sets with #2 and #6, the UE uses a codeword with a TPMI of 2 The determined antenna port 2 performs transmission. For frequency domain sets with #3 and #7, the UE uses a codeword with a TPMI of 3. The determined antenna port 3 performs transmission.
具体而言,上述描述的预设规则可以是UE根据用户的指示确定的,也可以是根据天线端口的传输能力结合频域集合的资源大小等因素确定的。例如,如果在非均匀划分的情况下,对于具有4个RB资源的调度资源,可以将其划分为{#0}的资源集合以及{#1,#2,#3}的资源集合。如果天线端口0的传输性能要优于天线端口1的传输性能的话,那么UE在分配天线端口时,则UE采用TPMI为0的码字
确定的天线端口0进行传输具有#1,#2,#3的资源集合。而对于#0的资源集合,UE采用TPMI为1的码字
确定的天线端口1进行传输。
Specifically, the preset rule described above may be determined by the UE according to the user's instruction, or may be determined according to factors such as the transmission capability of the antenna port in combination with the resource size of the frequency domain set. For example, if in the case of non-uniform division, the scheduling resource with 4 RB resources can be divided into a resource set of {#0} and a resource set of {#1, #2, #3}. If the transmission performance of antenna port 0 is better than that of antenna port 1, then when the UE allocates antenna ports, the UE uses the code word with TPMI 0 The determined antenna port 0 for transmission has resource sets of #1, #2, and #3. For the resource set # 0, the UE uses a codeword with a TPMI of 1. The determined antenna port 1 performs transmission.
对支持4天线端口部分相干能力的UE,4个天线端口分为两组,每组包括2个天线端口。组内的天线端口具有相干能力,因此可以同时发送。例如,组0包括天线端口0和2,组1包括天线端口1和3。For UEs that support partial coherence of 4 antenna ports, the 4 antenna ports are divided into two groups, and each group includes 2 antenna ports. The antenna ports in the group have coherence capabilities, so they can transmit simultaneously. For example, group 0 includes antenna ports 0 and 2, and group 1 includes antenna ports 1 and 3.
例如,基站为支持4天线端口部分相干能力的UE调度了4个RB以1层发送上行传输,并指示复合码字,TPMI={29}时,表示表2中TPMI为4、8的组合。UE将调度的资源4个RB分为2部分,分别在组0的天线端口0和2以及组1的天线端口1和3上发送。即组0对应TPMI为4的码字
组1对应TPMI为8的码字
For example, the base station schedules 4 RBs for a UE that supports partial coherence capabilities of 4 antenna ports to send uplink transmission at layer 1, and indicates a composite codeword. When TPMI={29}, it means that TPMI is a combination of 4 and 8 in Table 2. The UE divides the 4 RBs of the scheduled resource into 2 parts, and transmits them on antenna ports 0 and 2 of group 0 and antenna ports 1 and 3 of group 1 respectively. That is, group 0 corresponds to the code word with TPMI 4 Group 1 corresponds to the code word with TPMI 8
基站为UE调度或激活上行传输,指示以下至少之一:上行传输的时频域资源信息、预编码信息。The base station schedules or activates uplink transmission for the UE, and indicates at least one of the following: time-frequency domain resource information and precoding information for uplink transmission.
上述调度上行传输的信息可以在一个物理层下行控制信息(Downlink Control Information,DCI)中承载,也可以在多个DCI中承载。The foregoing information for scheduling uplink transmission may be carried in one physical layer downlink control information (Downlink Control Information, DCI), or may be carried in multiple DCIs.
当使用1个DCI承载时,DCI对应所有的频域资源集合,包括所有频域资源集合的时频域资源信息、预编码信息。When one DCI bearer is used, the DCI corresponds to all frequency domain resource sets, including time-frequency domain resource information and precoding information of all frequency domain resource sets.
当使用多个DCI承载时,每个DCI对应一个频域资源集合,包括该频域资源集合的时频域资源信息、预编码信息。When multiple DCI bearers are used, each DCI corresponds to a frequency domain resource set, including time-frequency domain resource information and precoding information of the frequency domain resource set.
UE至少根据DCI信息确定频域资源集合的个数以及各个频域资源集合对应的天线端口。The UE determines the number of frequency domain resource sets and the antenna ports corresponding to each frequency domain resource set at least according to the DCI information.
根据M个空域资源信息发送所述N个频域资源集合承载的所述上行传输,还包括:在所述N个频域资源集合中的每个所述频域资源集合上均承载所述上行传输。Sending the uplink transmission carried by the N frequency domain resource sets according to the M spatial resource information further includes: carrying the uplink transmission on each of the N frequency domain resource sets. transmission.
所述频域资源包括以下之一:资源块RB、资源单元RE。The frequency domain resource includes one of the following: a resource block RB and a resource unit RE.
需要说明的是,上行传输包括以下之一:PUSCH传输,物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)传输,SRS传输。资源集合包括以下之一:不同的RB(Resource Block,资源块)集合,不同的RE(Resource Element,资源单元)集合。RB与RE同LTE和新无线(New Radio,NR)技术中的定义,每个RB在频域包括12个RE。It should be noted that the uplink transmission includes one of the following: PUSCH transmission, physical uplink control channel (Physical Uplink Control Channel, PUCCH) transmission, and SRS transmission. The resource set includes one of the following: different RB (Resource Block, resource block) sets, and different RE (Resource Element, resource unit) sets. RB and RE are defined in LTE and New Radio (NR) technologies, and each RB includes 12 REs in the frequency domain.
将所述调度信息指示的频域资源分为N个频域资源集合,包括:所述将所述调度信息指示的资源平均划分为N个频域资源集合。例如,调度的资源是10个RB,N=2时,N个RB集合为大小一样的5个RB。Dividing the frequency domain resources indicated by the scheduling information into N frequency domain resource sets includes: dividing the resources indicated by the scheduling information into N frequency domain resource sets on average. For example, when the scheduled resource is 10 RBs and N=2, the set of N RBs is 5 RBs of the same size.
所述调度信息指示的资源的数量为N倍的2,3,5的非负整数次方的乘积。The number of resources indicated by the scheduling information is N times the product of 2, 3, and 5 to the power of a non-negative integer.
具体而言,例如,N=2时,调度的资源RB数量限制为2倍的2,3,5的任意非负整数次方的倍数。N为不小于2的正整数。Specifically, for example, when N=2, the number of scheduled resource RBs is limited to a multiple of any non-negative integer power of 2, 3, and 5. N is a positive integer not less than 2.
2的1次方,3的0次方,5的0次方与N=2的乘积为4;2 to the 1st power, 3 to the 0 power, and the product of 5 to the 0 power and N=2 is 4;
2的0次方,3的1次方,5的0次方与N=2的乘积为6;2 to the 0 power, 3 to the 1 power, and the product of 5 to the 0 power and N=2 is 6;
2的0次方,3的0次方,5的1次方与N=2的乘积为10;The product of 2 to the 0 power, 3 to the 0 power, 5 to the 1 power and N=2 is 10;
2的2次方,3的1次方,5的0次方与N=2的乘积为24。The product of 2 to the 2nd power, 3 to the 1st power, 5 to the 0 power and N=2 is 24.
而如果N=3时,则RB数量可以包括:6,9,15,12,27,75等。N=4,5……等以此类推,在此不做过多说明。And if N=3, the number of RBs may include: 6, 9, 15, 12, 27, 75, etc. N=4,5...and so on, so I won't elaborate on it here.
将所述调度信息指示的频域资源分为N个频域资源集合,包括:根据所述调度信息指示的频域资源的资源顺序,依次为每个所述频域资源集合分配所需数量的所述频域资源。Dividing the frequency domain resources indicated by the scheduling information into N frequency domain resource sets includes: according to the resource sequence of the frequency domain resources indicated by the scheduling information, sequentially allocating a required number of frequency domain resources to each of the frequency domain resource sets The frequency domain resources.
在资源集合为RB集合时,例如,调度的资源的RB包含4个RB,依次编号为RB#3,RB#4,RB#5,RB#6,N为2,均匀分配为两个RB集合,则两个RB集合各包括2个RB,第一个RB集合包括RB#3,RB#4,第一个RB集合包括RB#5,RB#6。When the resource set is an RB set, for example, the RB of the scheduled resource contains 4 RBs, which are sequentially numbered RB# 3, RB#4, RB#5, RB#6, N is 2, and are evenly allocated to two RB sets , The two RB sets each include 2 RBs, the first RB set includes RB# 3 and RB#4, and the first RB set includes RB#5 and RB#6.
又如,调度的资源的RB包含4个RB,这4个RB不是连续的RB,编号为RB#3,RB#4,RB#7,RB#8,N为2,均匀分配为两个RB集合,则两个RB集合各包括2个RB,第一个RB集合包括RB#3,RB#4,第一个RB集合包括RB#7,RB#8。For another example, the RB of the scheduled resource contains 4 RBs, these 4 RBs are not consecutive RBs, numbered RB# 3, RB#4, RB#7, RB#8, N is 2, and evenly allocated as two RBs Set, the two RB sets each include 2 RBs, the first RB set includes RB# 3 and RB#4, and the first RB set includes RB#7 and RB#8.
在资源集合为RE集合时,例如,将调度的资源分为N=2个不同的RE集合时,每个RB中的RE都被分为2个RE集合。RB中包括12个RE,RE编号小的6个RE属于第一个RE集合,RE编号大的6个RE属于第二个RE集合。其中部分RE可能是用于发送DMRS的RE。When the resource set is an RE set, for example, when the scheduled resources are divided into N=2 different RE sets, the REs in each RB are divided into 2 RE sets. The RB includes 12 REs, the 6 REs with the smaller RE numbers belong to the first RE set, and the 6 REs with the larger RE numbers belong to the second RE set. Some of the REs may be REs used to send DMRS.
将所述调度信息指示的频域资源分为N个频域资源集合,包括:根据所述调度信息指示的频域资源的资源顺序,轮流为每个所述资源集合分配的频域资源直到分配完毕。Dividing the frequency domain resources indicated by the scheduling information into N frequency domain resource sets includes: according to the resource sequence of the frequency domain resources indicated by the scheduling information, the frequency domain resources allocated to each resource set are allocated in turn until allocated complete.
例如,调度的资源的RB包含4个RB,依次编号为RB#3,RB#4,RB#5,RB#6,N为2,均匀分配为两个RB集合,则两个RB集合各包括2个RB,第一个RB集合包括RB#3,RB#5,第一个RB集合包括RB#4,RB#6。For example, the RB of the scheduled resource contains 4 RBs, which are sequentially numbered RB# 3, RB#4, RB#5, RB#6, and N is 2, evenly allocated to two RB sets, then the two RB sets each include 2 RBs, the first RB set includes RB# 3 and RB#5, and the first RB set includes RB#4 and RB#6.
又例如,将调度的资源分为N=2个不同的RE集合时,每个RB中的RE都被分为2个RE集合。RB中包括12个RE,RE编号为偶数的6个RE属于第一个RE集合,编号为奇数的6个RE属于第二个RE集合。其中部分RE可能是用于发送DMRS的RE。For another example, when the scheduled resources are divided into N=2 different RE sets, the REs in each RB are divided into 2 RE sets. The RB includes 12 REs, the 6 REs with an even number of REs belong to the first RE set, and the 6 REs with an odd number belong to the second RE set. Some of the REs may be REs used to send DMRS.
将所述调度信息指示的频域资源分为N个频域资源集合,包括:根据所述频域资源集合对应的所述空域资源信息的最大功率,为每个所述频域资源集合分配所述频域资源。Dividing the frequency domain resources indicated by the scheduling information into N frequency domain resource sets includes: according to the maximum power of the space resource information corresponding to the frequency domain resource sets, allocating all the frequency domain resources The frequency domain resources.
具体而言,非均匀的N个RB集合中包含RB的数量与RB集合对应的天线端口或天线端口组合所支持的最大功率有关。即,天线端口或天线端口组合所支持的最大功率越高,该天线端口或天线端口组合对应的RB集合中包含的RB数量越多。因此,天线端口或天线端口组合对应的RB集合中包含的RB数量与 天线端口或天线端口组合所支持的最大功率的线性值成正比。Specifically, the number of RBs included in the non-uniform N RB set is related to the maximum power supported by the antenna port or antenna port combination corresponding to the RB set. That is, the higher the maximum power supported by the antenna port or antenna port combination, the more RBs included in the RB set corresponding to the antenna port or antenna port combination. Therefore, the number of RBs included in the RB set corresponding to the antenna port or antenna port combination is proportional to the linear value of the maximum power supported by the antenna port or antenna port combination.
例如,UE支持两个发送天线端口,天线端口0的最大发送功率是23dBm,天线端口1的最大发送功率是20dBm,则天线端口0与天线端口1的最大发送功率的线性比值为2:1。调度的资源的RB数量以2:1的比例分配给两个天线端口。当调度的资源的RB数量为15时,天线端口0和天线端口1发送的RB数量分别为10和5。For example, the UE supports two transmit antenna ports, the maximum transmit power of antenna port 0 is 23 dBm, and the maximum transmit power of antenna port 1 is 20 dBm, then the linear ratio of the maximum transmit power of antenna port 0 to antenna port 1 is 2:1. The number of RBs of the scheduled resources is allocated to the two antenna ports in a ratio of 2:1. When the number of RBs of the scheduled resource is 15, the number of RBs transmitted by antenna port 0 and antenna port 1 are 10 and 5, respectively.
因此,基站需要保证为UE分配的资源的RB数量在以N个天线端口或天线端口组合所支持的最大功率的线性值为比例分割为N个RB集合后,每个RB集合中包含的RB数量为整数。Therefore, the base station needs to ensure that the number of RBs allocated to the UE is divided into N RB sets in proportion to the linear value of the maximum power supported by the N antenna ports or antenna port combinations, and the number of RBs contained in each RB set Is an integer.
根据M个空域资源信息发送所述N个频域资源集合承载的所述上行传输,还包括:将所述上行传输的总发送功率分配在M个所述空域资源信息上;每个所述空域资源信息分配的发送功率在对应的所述频域资源集合的RE上均匀分配。Sending the uplink transmission carried by the N frequency domain resource sets according to the M spatial resource information further includes: allocating the total transmit power of the uplink transmission to the M spatial resource information; each of the spatial domains The transmission power allocated by the resource information is evenly allocated on the REs of the corresponding frequency domain resource set.
例如:基站调度UE用2天线端口发送PUSCH传输,调度信息指示的频域资源为RB0和RB1。UE将频域资源分为两组,频域资源集合0包括RB0,频域资源集合1包括RB1,并且分别用天线端口0和天线端口1发送RB0和RB1上承载的PUSCH传输。For example, the base station schedules the UE to use 2 antenna ports to send PUSCH transmission, and the frequency domain resources indicated by the scheduling information are RB0 and RB1. The UE divides frequency domain resources into two groups, frequency domain resource set 0 includes RB0, and frequency domain resource set 1 includes RB1, and uses antenna port 0 and antenna port 1 to transmit PUSCH transmissions carried on RB0 and RB1, respectively.
UE根据基站配置的功率控制参数以及DCI信息确定PUSCH的总发送功率P。所谓的总发送功率是指所有天线端口的发送功率之和。UE将总发送功率分配在两个天线端口上,如,每个天线端口的发送功率为P/2。The UE determines the total transmission power P of the PUSCH according to the power control parameters configured by the base station and the DCI information. The so-called total transmission power refers to the sum of the transmission power of all antenna ports. The UE allocates the total transmission power to the two antenna ports, for example, the transmission power of each antenna port is P/2.
对于天线端口0,P/2的功率在RB0的所有RE上平均分配。对于天线端口1,P/2的功率在RB1的所有RE上平均分配。For antenna port 0, the power of P/2 is equally distributed among all REs of RB0. For antenna port 1, the power of P/2 is equally distributed among all REs of RB1.
将所述上行传输的总发送功率分配在M个所述空域资源信息上,包括:将所述上行传输的总发送功率平均分配在M个所述空域资源信息上;或,将所述上行传输的总发送功率按照M个所述空域资源信息对应的频域资源数量之间的比例分配在M个所述空域资源信息上。例如:天线端口0对应的频域资源分配的资源为4个RB,天线端口1对应的频域资源分配的资源为2个RB。当上行传输的总发送功率为P时,天线端口0和天线端口1的发送功率比为2:1,即分别为2/3P和1/3P。通过最大发送功率的线性值为比例分割的方式,可以支持发 送的最大发送功率高的天线端口更可能发挥其高的发送功率的能力。可以在保证各个RE的功率谱密度均匀的情况下,最大化利用各天线端口的PA能力Allocating the total transmit power of the uplink transmission to the M pieces of airspace resource information includes: equally allocating the total transmit power of the uplink transmission to the M pieces of airspace resource information; or, transmitting the uplink The total transmit power of is allocated to the M pieces of airspace resource information according to the ratio between the number of frequency domain resources corresponding to the M pieces of airspace resource information. For example, the frequency domain resource corresponding to antenna port 0 is allocated 4 RBs, and the frequency domain resource corresponding to antenna port 1 is allocated 2 RBs. When the total transmit power of uplink transmission is P, the transmit power ratio of antenna port 0 and antenna port 1 is 2:1, that is, 2/3P and 1/3P, respectively. Through the proportional division of the linear value of the maximum transmission power, the antenna port with the high maximum transmission power that can support transmission is more likely to exert its high transmission power capability. The PA capability of each antenna port can be maximized while ensuring that the power spectral density of each RE is uniform
