Uplink MIMO transmission of the NR system is divided into two types: codebook-based (codebook based) transmission and non-codebook based (non-codebook based) transmission.

Specifically, the precoding codeword information includes at least one of: precoding codeword, precoding codeword index, precoding codeword grouping index.

In particular, a precoding codeword, also referred to as a precoding matrix, refers to one precoding codeword out of a predefined set of precoding codewords called a precoding codebook. The precoding codeword index is also referred to as tpmi (transmittedprecoding Matrix indicator).

In particular, the spatial relationship comprises at least one reference signal information. And the reference signal information includes at least one of: reference signals, reference signal resources, a set of reference signal resources, a grouping of reference signal resources. Or, the reference signal information includes at least one of: reference signal index, reference signal resource set index, reference signal resource grouping index.

Sending the uplink transmission carried by the N frequency domain resource sets according to the M pieces of space domain resource information, wherein the uplink transmission comprises the following steps:

(1) sending the uplink transmission carried by the frequency domain resource set according to the antenna port indicated by the antenna port information;

(2) sending the uplink transmission carried by the frequency domain resource set according to the antenna panel indicated by the antenna panel information;

(3) sending the uplink transmission carried by the frequency domain resource set according to a transmission chain indicated by the transmission chain information;

(4) sending the uplink transmission carried by the frequency domain resource set according to the beam indicated by the beam information;

for example, the uplink transmission carried by the frequency domain resource set 0 is transmitted by using the antenna port 0. And sending the uplink transmission carried by the frequency domain resource set 0 by using the antenna panel 0. And sending the uplink transmission carried by the frequency domain resource set 0 by using the beam 0. And sending the uplink transmission carried by the frequency domain resource set 0 by using the transmission chain 0.

(5) Sending the uplink transmission carried by the frequency domain resource set according to a non-zero power antenna port in a precoding code word indicated by the precoding code word information;

specifically, the precoding code word is a matrix, rows of the matrix correspond to antenna ports, and columns of the matrix correspond to layers. If matrix elements of a row of the precoding code word are all 0, an antenna port corresponding to the row of the precoding code word is an antenna port with zero power. If the matrix elements of a row of the precoding code word are not all 0, the antenna port corresponding to the row of the precoding code word is a non-zero power antenna port.

For example, for precoding matrix

For a 4 antenna port, 2 layers. Where

antenna ports

0,1 are zero power antenna ports and

antenna ports

2,3 are non-zero power antenna ports.

(6) Sending the uplink transmission carried by the frequency domain resource set according to the transmission parameters with the same spatial relationship information;

(7) and sending the uplink transmission carried by the frequency domain resource set according to the transmission parameters with the same reference signal information.

For example, in the beam management process, the base station schedules the UE to transmit different SRSs using different transmission parameters, such as different beams, or different transmission filters, assuming that a total of 3 SRSs are transmitted, and identified by

SRIs

0,1, and 2, respectively. When the base station schedules SRI 0 and SRI1 to send uplink transmission, the UE divides the resources indicated by the scheduling information into N-2 frequency domain resource sets, and sends a first frequency domain resource set by using the transmission parameters or sending filters for sending the SRI 0; the second set of frequency domain resources is transmitted using the transmission parameters or transmit filter of transmit SRI 1.

Specifically, the number M of spatial domain resource information is determined according to the number of antenna ports included in SRS resources or SRS resource sets corresponding to the SRI domain included in the scheduling information for uplink transmission.

For example, if the number of SRS ports indicated in the SRS resource corresponding to the SRI field included in the scheduling information for uplink PUSCH is 4, the number M of spatial resource information is 4. When the null resource information indicates an antenna port, the number of antenna ports of the PUSCH is 4.

Specifically, the number M of the spatial domain resource information is determined according to the number of antenna ports included in the SRS resource or SRS resource set corresponding to the SRI domain included in the scheduling information for uplink transmission and the precoding information in the scheduling information for uplink transmission.

Determining the number M of the airspace resource information according to the content of at least one of the following in the scheduling information of the uplink transmission: the number of antenna ports contained in the SRS resource corresponding to the SRI domain; the number of antenna ports contained in a measurement reference signal SRS resource set corresponding to an SRI domain; and precoding information.

The precoding information in the scheduling information of the uplink transmission comprises one of the following indications: TPMI, number of layers.

Specifically, a precoding matrix for uplink transmission is determined according to the number of antenna ports included in the SRS resource or SRS resource set corresponding to the SRI field included in the scheduling information for uplink transmission and precoding information in the scheduling information for uplink transmission. And determining the number M of the space domain resource information according to the uplink transmission precoding matrix, wherein the number M comprises the number of rows of which M is equal to the non-zero power in the matrix.

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

In particular, in wireless communication systems, signals attenuate as distance increases during propagation. The maximum transmit power of the user equipment determines its communication range. The higher the maximum transmit power, the longer the distance its signal can travel. Therefore, the communication system may specify the maximum transmission power of the user equipment. For example, in the LTE system of 3GPP, the UE generally needs to support power class (power class)3, i.e. 23 dBm. In addition, some UEs also support a power level of 2, i.e., 26 dBm.

The UE may configure 1 or more antenna ports (antenna ports). Each antenna port corresponds to one or more antenna chains (antenna chains) or radio frequency RF chains), and each antenna port or antenna chain corresponds to a PA (power amplifier). For simplicity of description, it is assumed that there is one PA for each antenna port. If the antenna port corresponds to multiple PAs, the power of the multiple PAs together is the power capability of the antenna port.

For a UE supporting multiple antenna ports, to meet a specific power class, each antenna port or a part of the antenna ports may reach the power required by the power class, or all the antenna ports may not reach the power required by the power class, but some or all of the antenna ports may be combined to reach the power required by the power class. For example, for a UE supporting 2 antenna ports, the maximum transmit power needs to be 23dBm when supporting power class 3. The power supported by the 2 antenna ports may be one of:

23dBm +23 dBm; 23dBm +20 dBm; or 20dBm +20dBm

When all antenna ports cannot independently reach the maximum transmission power, a combination of a plurality of antenna ports is required to reach the maximum transmission power. For example, two 20dBm antenna ports transmit simultaneously up to 23dBm transmit power. When transmitting only MIMO 1 layer data, the base station may schedule the UE to transmit using two antenna ports if there is coherence capability between the two antenna ports, and use different codewords to make the two antenna ports best match the actual channel. Coherent capability (coherent) exists between the antennas, which means that the phase difference between the antennas can be controlled. If there is no coherence capability (non coherence) between the two antenna ports, the base station is generally unable to schedule the UE to transmit on both antenna ports because the phase between the two antenna ports is not controllable and thus the interference between the ports is not controllable. If two antenna ports are used to transmit the same data, the signals between the antenna ports may be superimposed positively to double the power or negatively to reduce to 0 power.

When the PUSCH transmission is transmitted in a MIMO multi-antenna manner, two types are included: codebook-based (codebook based), non-codebook-based (non codebook based).

Codebook-based transmission refers to precoding in which a base station selects a codeword from a predefined codebook for uplink transmission. A codebook is a predefined set of codewords, including at least one codeword (codeword). Each codeword is a matrix used for precoding of multiple antenna ports at the transmitting end. 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 for 2 antenna ports and 1 layer, where the codebook includes 6 codewords, and each codeword is in two rows and one column. The codeword is identified by TPMI (Transmitted Precoding Matrix Indicator).

Generally, a base station determines the number of antenna ports according to the capability of a UE transmitting antenna, and schedules the UE to transmit an SRS for measuring an uplink channel, also called channel sounding. And the base station determines MIMO parameters including the number of layers, precoding and the like for subsequent uplink transmission according to the channel measurement result, and then assigns a determined precoding matrix, namely TPMI, for the uplink transmission of the UE. And the UE uses the appointed precoding matrix to precode the transmitted data and sends the precoded data to the base station.

The base station may configure different SRS resources for the UE, and the UE sends different SRS on the different SRS resources, so the base station further needs to indicate SRS Resources (SRI) for uplink transmission. For example, different SRS resources correspond to different transmission beam resources (groups), different antenna panels (panels), or different precoding schemes for antenna ports.

For non-codebook based transmissions, the base station need not indicate the TPMI to the UE, but if the UE uses multiple antenna ports, the UE may determine the precoding information for the transmission itself.

TABLE 1

When a UE configures multiple antenna ports, the capability of adjusting the phase difference of transmitted signals between the antenna ports is classified into different coherent (coherent) capabilities: fully coherent (full coherent), partially coherent (partial coherent), and non-coherent (non-coherent). UE support of high level of coherence capability downwards. The full coherence is higher than the partial coherence, and the partial coherence is higher than the non-coherence.

Non-Coherent (Non Coherent) capability means that the phase difference between antenna ports cannot be accurately adjusted; the partial coherence (partial coherence) capability means that only a part of antenna ports can be accurately adjusted for phase difference, and the full coherence (full coherence) capability means that all antenna ports can be accurately adjusted for phase difference.

Non-coherent capable UEs can only support codewords designed for non-coherent capable UEs; the partially coherent capable UE may support codewords designed for the non-coherent capable UE and codewords designed for the partially coherent capable UE; a fully coherent capable UE may support codewords designed for non-coherent capable UEs, codewords designed for partially coherent capable UEs, and codewords designed for fully coherent capable UEs.

For example, a full coherence capable UE may also support partially coherent and non-coherent transmissions. Partially coherent UEs also support non-coherent transmission. As shown in table 1, in the codebook of 2 antenna ports and 1 layer, each of the matrices of TPMI0 and TPMI 1 has an antenna port of 0, that is, the matrix is only used for one antenna port transmission, which is also called antenna port selection, or antenna port selection for short, or antenna selection. TPMI0 and 1 are designed for non-coherent capable UEs. TPMI 2 to 5 are used for both antenna ports, with phase differences between the antenna ports. The TPMI 2 to 5 codewords are originally designed for full coherence capable UEs. The 2 antenna ports have only a fraction of the total coherent and non-coherent.

Table 2 is a codebook for 4 antenna port 1 layers. The 4-antenna port is partially coherent in addition to fully coherent and non-coherent. Only the codeword of 1 non-zero element of the 4 elements is used for non-coherent transmission, the codewords of two non-zero elements are used for partially coherent transmission, and the codewords of four non-zero elements are used for fully coherent transmission. The code words shown in table 2 are for 4 antenna ports, and the 4 antenna ports are respectively marked as antenna ports 0-3. The code words for partially coherent transmission in table 2 assume that

antenna ports

0 and 2 are one group, 1 and 3 are the other group, the antenna ports in the group have coherence capability, i.e., the phase difference can be controlled, and no coherence capability exists between the groups.

TABLE 2

When a device transmits using only partial antennas, the maximum power limit is equivalent to the maximum power limit when all antennas transmit, referred to as full power (or full rate) transmission.

For non-codebook based transmissions, the prior art has been able to support its utilization to maximum power, i.e., to support full power transmission. For codebook-based transmission, the prior art can only support full power transmission for fully coherent capable UEs, and cannot support full power transmission for partially coherent and non-coherent capable UEs.

The lack of support for full power transmission for partially coherent as well as non-coherent capable UEs is manifested in two ways:

the UE is not allowed to use codewords that exceed its coherence capability. For example, a UE supporting only non-coherent capability cannot use partial, full coherent capability codewords. The UE supporting the partial and non-logical capabilities cannot use the full-logical capability code word. For example, in Table 2, non-coherent capable UEs can only use TPMI0 ~ 3, partially coherent capable (can be downward compatible to support non-coherent capability) UEs can use TPMI0 ~ 11, and fully coherent capable (can be downward compatible to support partial and non-coherent capability) UEs can use all codewords.

The maximum transmit power per antenna port is limited to a fraction of the maximum number of antenna ports. For example, when 4 antenna ports are supported at maximum, each antenna port is limited to 1/4 of the maximum power of the maximum transmission power of the UE.

That is, when the maximum antenna port supported is 4, for the UE with non-coherent capability, only one antenna port can be selected for transmission in an antenna selection manner, 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 allowed power of the uplink transmission of the UE.

It is generally considered that, when a fully coherent codeword is used for a non-coherent UE, interference between antenna ports is not controllable because the phases of the antenna ports cannot be adjusted as required. I.e. the phase difference between the antenna ports is random. But if the scheme of antenna selection only is used, the direct loss of 3/4 transmission power is equivalent, and the effect of the loss on the performance is also considerable.

Therefore, intelligent systems should not have such a limitation on power. Non-coherent capable UEs should be allowed to use partial, full coherent capable codewords, and partial coherent capable UEs to use full coherent capable codewords. There may be an evaluation method, where if the performance loss caused by random interference between antenna ports is greater than the performance loss caused by power reduction due to a reduction in the number of antenna ports, a mode of antenna port reduction, that is, antenna port selection, or antenna port group selection, is adopted; otherwise, a non-antenna port (group) selection mode is adopted.

The evaluation method comprises selecting antenna port (group) selection or non-antenna port (group) selection according to the performance of a receiving end. For example, which performance is superior to which reception performance is selected, compared to the reception performance of the mode selected by the antenna port(s) and the mode selected by the non-antenna port(s).

Non-antenna port (group) selection, i.e. allowing the UE to use codewords that exceed its coherence capability, includes the following two ways:

mode 1: multiple antenna ports all transmit transmissions, with random interference between antenna ports.

Mode 2: multiple antenna ports all send transmissions, and different antenna ports carry uplink transmissions on different frequency domain resources, respectively.

For convenience of description, the conventional codewords are classified into 3 types: antenna port selection, antenna port group selection, full antenna port.

Considering the partial coherence capability of 4 antenna ports, a more general description is:

the traditional mode is as follows: for the UE with incoherent capability, only the code word selected by the antenna port can be used; for a partially coherent capable UE, a codeword for antenna port selection and antenna port group selection may be used; for a full coherence capable UE, the above 3 classes of codewords may be used.

Fig. 2 is a diagram of scheduling resource transmission according to an embodiment of the present application. As shown in fig. 2, the UE supports 2 antenna ports, and when the UE supports only the non-coherent capability, the UE can only select the antenna port selection mode with TPMI of 0 and 1 in the conventional mode. When TPMI is selected to be 0, the TPMI can only be transmitted through antenna port 0, which corresponds to port #0 in fig. 2; when TPMI is selected to be 1, i.e. transmission is possible only with antenna port 1, corresponding to port #1 in fig. 2.

However, in this conventional manner, it is obvious that the transmission power of the UE cannot be fully used, such as the case in fig. 2, which directly loses 1/2 the transmission power.

Similarly, when the coherence capability type is a partial coherence capability, a similar problem also exists.

When the coherent capability type is non-coherent capability or partial coherent capability, the UE selects antenna ports for transmitting the N frequency domain resource sets from the antenna ports according to the identification information of the code words in the first spreading code word set; wherein the first set of spreading codewords comprises codewords above a coherence capability of the UE.

Specifically, there is a random phase difference between antenna ports corresponding to the codewords of the first set of spreading codewords.

Fig. 3 is a schematic diagram of another scheduled resource transmission according to an embodiment of the present application. As shown in fig. 3, the UE supports 2 antenna ports, and when the UE supports only the non-coherent capability, the UE can only select the antenna port selection mode with TPMI of 0 and 1 in the conventional mode, as shown in table 1. With the above extension 1, the UE also supports one or more of the codewords of TPMI ═ {2,3,4,5 }. When TPMI is {2}, i.e. the code word is

The UE transmits layer 1 data on RB resources scheduled by the base station in the same manner on both

antenna ports

0 and 1, i.e., no additional phase difference is added between

antenna ports

0 and 1.

Due to the incoherence between the antenna ports, the phase between the antenna ports is not controllable, the actual codeWord is equivalent to

Where α is an arbitrary phase value, or a random phase value.

Specifically, the indication information of the precoding code word corresponding to the coherence capability of the spatial domain resource higher than the spatial domain resource information is realized by the following method: to avoid the transmission power loss in fig. 2 and fig. 3, it is necessary to send transmission on different frequency domain resources through the antenna ports or antenna port groups corresponding to the codewords of the first spreading codeword set, that is, select the antenna ports for transmitting the N frequency domain resource sets. That is, two antenna ports each send transmissions on only one set of frequency domain resources, rather than both antenna ports transmitting the same frequency domain resources. Therefore, the UE firstly divides the scheduling resources into N frequency domain resource sets according to the scheduling indication information sent by the base station and/or the predetermined allocation mode of the base station. And then realizing resource transmission on the N frequency domain resource sets according to the antenna ports or antenna port groups corresponding to the code words of the first spreading code word set.

For example, the UE supports 2 antenna ports with non-coherent capability, and besides the conventional antenna port selection mode with TPMI of 0 and 1, as shown in table 1, the UE also supports one or more of code words with TPMI ═ 2,3,4,5 using the above extension mode 1.

When TPMI is {2}, i.e. the code word is

In the manner described in fig. 2, since the antenna ports are incoherent, and therefore the phases between the antenna ports are not controllable, unpredictable interference exists 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 two antenna ports respectively transmit transmission on only one frequency domain resource set. Thus, there is no mutual interference among the ports.

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 fig. 4, in a power limited scenario, the following advantages exist when the different antenna ports of fig. 4 transmit transmission in a frequency division manner: compared with the antenna port selection mode of fig. 2 and the forced transmission mode of fig. 3 in which multiple antenna ports all transmit, each antenna port only needs to transmit a half-frequency resource, and when the power is limited, that is, the antenna port transmits at the maximum transmission power, higher power can be transmitted on each RE, so the coverage can be enhanced.

Compared with fig. 3, the manner in which multiple antenna ports are all forcibly transmitted results in unpredictable interference between the antenna ports, and the manner in fig. 4 is frequency division multiplexing between the antenna ports, so that there is no interference problem and transmission can be transmitted with the same power and better performance.

For a UE supporting a 4-antenna port partial coherence capability, the 4 antenna ports are divided into two groups, each group including 2 antenna ports. The antenna ports within a group have coherent capabilities and therefore can transmit simultaneously. For example, group 0 includes

antenna ports

0 and 2, and group 1 includes

antenna ports

1 and 3.

For example, when the base station schedules 4 RBs for a UE supporting 4 antenna port partial coherence capability to transmit uplink transmission in layer 1 and indicates TPMI exceeding the coherence capability of the UE {12}, see table 2, that is, the codeword is

The UE divides the scheduled resources 4 RBs into 2 parts, and transmits on

antenna ports

0 and 2 of group 0 and

antenna ports

1 and 3 of group 1, respectively.

Determining the number of frequency domain resource packets is also related to coherence capability.

It should be noted that: in the scheduled frequency domain resources, a part of the antenna ports transmit a part of the frequency domain resources, which means that the corresponding part of the frequency domain resources are placed with data to be transmitted, and the rest of the frequency domain resources are not placed with data to be transmitted. For example, antenna port #0 in fig. 4 transmits RB #0 and RB #1, meaning that data to be transmitted is placed at the positions of RB #0 and RB #1, and data to be transmitted is not placed at RB #2 and RB # 3. Similarly, antenna port #1 transmits RB #2 and RB #3, which means that data to be transmitted is placed at the positions of RB #2 and RB #3, and data to be transmitted is not placed at RB #0 and RB # 1.

Specifically, the indication information for representing a plurality of precoding codewords conforming to coherence capability is implemented as follows:

TPMI in table 1 of 6, 7 is not used and can be used for indication information of precoding codewords that indicate a plurality of coherent capabilities that are compliant. For example, TPMI ═ {6} represents a combination of TPMI0 and 1, a codeword with TPMI0 for antenna port 0, and a codeword with TPMI 1 for antenna port 1.

In table 2, TPMI 28, 29, 30, and 31 are not used, and are used as indication information of precoding codewords indicating a plurality of coherent capabilities. For example, TPMI ═ {28} represents a combination of TPMI0, 1, 2, and 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.

Similarly, assuming that there are 8 RB resources, i.e., #0 to #7, in the scheduling resources, when performing frequency domain resource transmission, the UE first determines 4 antenna ports supporting the non-coherent capability according to its own capability, and then divides the 8 RB scheduling resources into 4 frequency domain resource sets, e.g., a frequency domain set having #0, #4, a frequency domain set having #1, #5, a frequency domain set having #2, #6, and a frequency domain set having #3, # 7. Then, corresponding port allocation is performed according to the order of the frequency domain sets or a preset rule by using TPMI ═ {28}, for example, for the frequency domain sets with #0, #4, the UE employs a codeword with TPMI of 0

The determined antenna port 0 is used for transmission, and for the frequency domain sets of #1 and #5, the UE adopts the code word with TPMI of 1

And transmitting through the determined antenna port 1. For the frequency domain set with #2, #6, the UE adopts the code word with TPMI of 2

And the determined antenna port 2 transmits. And for the probe with #3, #7The UE adopts code words with TPMI of 3

The determined antenna port 3 transmits.

Specifically, the preset rule described above may be determined by the UE according to the indication of the user, or may be determined according to 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, for a scheduled resource having 4 RB resources, it 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 the antenna ports, the UE adopts the code word with TPMI of 0

The determined antenna port 0 transmits a resource set having #0, #1, # 2. And for the frequency domain set of #3, the UE adopts the code word with TPMI of 1

And transmitting through the determined antenna port 1.

antenna ports

0 and 2, and group 1 includes

antenna ports

1 and 3.

For example, when the base station schedules 4 RBs for a UE supporting 4 antenna port partial coherence capability to transmit uplink transmission in layer 1 and indicates a composite codeword, and TPMI ═ {29} indicates that TPMI is a combination of 4 and 8 in table 2. The UE divides the scheduled resources 4 RBs into 2 parts, and transmits on

antenna ports

0 and 2 of group 0 and

antenna ports

1 and 3 of group 1, respectively. I.e. group 0 corresponds to code words having a TPMI of 4

Group 1 corresponds to code words with TPMI of 8

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 of uplink transmission.

The information for scheduling uplink transmission may be carried in one DCI or may be carried in a plurality of DCIs.

When 1 piece of DCI is used for bearing, the DCI corresponds to all frequency domain resource sets, including time-frequency domain resource information and precoding information of all the frequency domain resource sets.

When a plurality of DCIs are used for bearing, each DCI corresponds to one frequency domain resource set and comprises time-frequency domain resource information and precoding information of the frequency domain resource set.

And the UE determines the number of the frequency domain resource sets and the antenna ports corresponding to the frequency domain resource sets at least according to the DCI information.

Sending the uplink transmission carried by the N frequency domain resource sets according to the M space domain resource information, further comprising: and carrying the uplink transmission on each of the N frequency domain resource sets.

The frequency domain resources include one of: resource block RB, resource element RE.

It should be noted that the uplink transmission includes one of the following: PUSCH transmission, PUCCH transmission, SRS transmission. The set of resources includes one of: different sets of RBs (Resource blocks) and different sets of REs (Resource elements). RB and RE are as defined in LTE and NR techniques, and each RB includes 12 REs in the frequency domain.

Dividing the frequency domain resources indicated by the scheduling information into N frequency domain resource sets, including: and averagely dividing the resources indicated by the scheduling information into N frequency domain resource sets. For example, when the scheduled resource is 10 RBs and N is 2, the N RB sets are 5 RBs having the same size.

The number of resources indicated by the scheduling information is N times the product of 2,3,5 to the non-negative integer power.

Specifically, for example, when M is 2, the number of resource RBs scheduled is limited to 2 times a multiple of 2,3, and 5 to any non-negative integer power. M is a positive integer not less than 2.

The product of the power 1 of 2, the power 0 of 3, the power 0 of 5 and N-2 is 4;

the product of the 0 power of 2, the 1 power of 3, and the 0 power of 5 with N being 2 is 6;

the product of the power 0 of 2, the power 0 of 3, the power 1 of 5 and N-2 is 10;

the product of the power 2 of 2, the power 1 of 3, the power 0 of 5 and N-2 is 24.

And if M is 3, the RB number may include: 6,9,15, 12,27,75, etc. And M is 4,5 … …, etc., and so on, and will not be described in great detail herein.

Dividing the frequency domain resources indicated by the scheduling information into N frequency domain resource sets, including: and sequentially allocating the required number of frequency domain resources to each frequency domain resource set according to the resource sequence of the frequency domain resources indicated by the scheduling information.

When the resource set is an RB set, for example, the RBs of the scheduled resource include 4 RBs, which are numbered as RB #3, #4, #5, #6, and N is 2 in this order, and are uniformly allocated as two RB sets, the two RB sets each include 2 RBs, the first RB set includes RB #3, #4, and the first RB set includes RB #5, # 6.

As another example, the RBs of the scheduled resource include 4 RBs, the 4 RBs are not consecutive RBs, are numbered RB #3, #4, #7, #8, and N is 2, and are uniformly allocated into two RB sets, so that the two RB sets each include 2 RBs, the first RB set includes RB #3, #4, and the first RB set includes RB #7, # 8.

When the resource set is an RE set, for example, when the scheduled resource is divided into N — 2 different RE sets, the REs in each RB are divided into 2 RE sets. The RB includes 12 REs, and 6 REs with a small RE number belong to a first RE set and 6 REs with a large RE number belong to a second RE set. Wherein part of the REs may be REs for transmitting the DMRS.

Dividing the frequency domain resources indicated by the scheduling information into N frequency domain resource sets, including: and according to the resource sequence of the frequency domain resources indicated by the scheduling information, allocating the frequency domain resources to each resource set in turn until the allocation is finished.

For example, the RBs of the scheduled resource include 4 RBs, which are numbered RB #3, #4, #5, #6, and N is 2 in this order, and are uniformly allocated as two RB sets, and thus the two RB sets each include 2 RBs, the first RB set includes RB #3, #5, and the first RB set includes RB #4, # 6.

For another example, when the scheduled resource is divided into N — 2 different RE sets, the REs in each RB are divided into 2 RE sets. The RB includes 12 REs, and 6 REs with even-numbered REs belong to a first RE set and 6 REs with odd-numbered REs belong to a second RE set. Wherein part of the REs may be REs for transmitting the DMRS.

Dividing the frequency domain resources indicated by the scheduling information into N frequency domain resource sets, including: and distributing the frequency domain resources for each frequency domain resource set according to the maximum power of the space domain resource information corresponding to the frequency domain resource set.

Specifically, the number of RBs included in the non-uniform N RB sets 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 an antenna port or an antenna port combination is, the greater the number of RBs included in the RB set corresponding to the antenna port or the antenna port combination is. Therefore, the number of RBs included in the RB set corresponding to an antenna port or an antenna port combination is proportional to a linear value of the maximum power supported by the antenna port or the antenna port combination.

For example, the UE supports two transmit antenna ports, the maximum transmit power of antenna port 0 is 23dBm, the maximum transmit power of antenna port 1 is 20dBm, and 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 resource is allocated to two antenna ports in a ratio of 2: 1. When the number of RBs of the scheduled resource is 15, the numbers of RBs transmitted by antenna port 0 and antenna port 1 are 10 and 5, respectively.

Therefore, the base station needs to ensure that the number of RBs of the resource allocated to the UE is an integer after dividing the number of RBs into N RB sets in proportion to a linear value of the maximum power supported by N antenna ports or antenna port combinations.

Sending the uplink transmission carried by the N frequency domain resource sets according to the M space domain resource information, further comprising: distributing the total transmission power of the uplink transmission on the M pieces of space domain resource information; and the transmitting power distributed by each space domain resource information is uniformly distributed on the corresponding RE of the frequency domain resource set.

For example: the base station schedules the UE to transmit PUSCH transmission by using 2 antenna ports, and the frequency domain resources indicated by the scheduling information are RB0 and RB 1. The UE divides the frequency domain resources into two groups, frequency domain resource set 0 includes RB0, frequency domain resource set 1 includes RB1, and transmits PUSCH transmissions carried on RB0 and RB1 with antenna port 0 and antenna port 1, respectively.

And the UE determines the total transmission power P of the PUSCH according to the power control parameter configured by the base station and the DCI information. The total transmission power is the sum of the transmission powers of all antenna ports. The UE allocates the total transmit power over two antenna ports, e.g., each antenna port has a transmit power of P/2.

For antenna port 0, the power of P/2 is equally distributed over all REs of RB 0. For antenna port 1, the power of P/2 is equally distributed over all REs of RB 1.

Distributing the total transmission power of the uplink transmission on the M pieces of space domain resource information, including: distributing the total transmission power of the uplink transmission on M pieces of the space domain resource information in an average manner; or distributing the total transmission power of the uplink transmission on the M pieces of space domain resource information according to the proportion of the number of the frequency domain resources corresponding to the M pieces of space domain resource information. For example: the frequency domain resource diversity resource corresponding to antenna port 0 is 4 RBs, and the frequency domain resource diversity resource corresponding to antenna port 1 is 2 RBs. When the total transmission power of the uplink transmission is P, the transmission power ratio of antenna port 0 and antenna port 1 is 2:1, i.e., 2/3P and 1/3P, respectively. By dividing the linear value of the maximum transmission power into proportional values, the antenna port with high maximum transmission power can be supported to more possibly exert the capability of high transmission power. The PA capability of each antenna port can be maximally utilized under the condition of ensuring the power spectral density of each RE to be uniform
