Optionally, the execution sequence of step S202 and step S204 may be interchanged, that is, step S204 may be executed first, and then step S202 may be executed.

The present embodiment will be described below with reference to specific examples.

Example 1

The base station indicates through signaling that N sets of phase tracking reference signal information are configured on M subbands (frequency domain units), where M is a positive integer and N is a positive integer, the set of phase tracking reference signals includes configuration information of at least one PTRS, and the configuration information includes at least one of: the number of ports, a precoding method, frequency domain density, time domain density, power, an association relation with a Demodulation Reference Signal (DMRS), a frequency domain position of the PTRS, and the like;

there may be different precoding patterns for each sub-band, so the SRI or TPMI may be different, and thus the corresponding PTRS ports may be different.

For code-book based (codebook-based) uplink transmission, indication of corresponding PTRS port 0 for SRI port 0 and port 2, and corresponding PTRS port 1 for SRI port 1 and port 3 are supported in the current protocol. The terminal may therefore vary the SRI information across each sub-band, as well if each sub-band uses a different, over-precoded code.

Take a terminal that schedules three subbands as an example. If the SRI of sub-band 1 is port 0 and port 2, the SRI information of sub-band 2 is port 1 and port 2, and the SRI information of port 3 is port 1 and port 3. And the base station performs PTRS configuration according to the information of the terminal, and if the base station performs PTRS port configuration completely according to the SRI information at this time, it is possible to obtain SRI information indicating that the PTRS port 0 is used in the sub-band 1, SRI information indicating that the PTRS port 1 and the port 2 are used in the sub-band 2, and SRI information indicating that the PTRS port 1 is used in the sub-band 3 according to the corresponding relationship between the PTRS port and the SRI. At this time, the number of PTRS ports corresponding to sub-band 1 is 1, the number of PTRS ports corresponding to sub-band 2 is 2, and the number of PTRS ports corresponding to sub-band 3 is 1. At this time, the PTRS configuration between sub-bands is different, and even though sub-band 1 and sub-band 3 only need to configure 1 PTRS port, the PTRS ports are different. For the frequency domain density configuration of PTRS, since the number of PTRS ports and the port number of each sub-band configuration are different, each sub-band needs to be configured separately in the configuration of frequency domain density, as shown in fig. 3. At this time, since the number of PTRS ports and port indications configured for each sub-band are different, if the frequency domain density over the entire bandwidth is configured when the entire bandwidth scheduled for terminal data transmission is configured, it may occur that the PTRS ports and the frequency domain density configurations on some sub-bands do not correspond to each other. For example, at this time, the frequency domain density configured for PTRS port 0 is 2, if this density is configured in the whole bandwidth range, then PTRS port 0 cannot be configured at the position of sub-band 3, so that resource waste is caused if the sub-band 3 is still configured according to the position and density of PTRS port 0 without sending data, and if data is sent at this position by sub-band 3, interference is caused with PTRS port 0 configured here. Similarly, if PTRS port 1 is configured with a density of 2, this also occurs at the frequency domain location of sub-band 1. Therefore, the configuration of the number of ports and the frequency domain density of different PTRS for different sub-bands does not cause the problem, the configuration is performed according to the frequency domain density of the PTRS port 0 in the sub-band 1, the configuration is performed according to the frequency domain densities of the PTRS port 0 and the PTRS port 1 in the sub-band 2, the configuration is performed according to the related information of the PTRS port in the sub-band 3, data or other signals can be sent at a position where the PTRS is not sent, at this time, resource utilization can be better performed, and extra interference can not be generated with reference to the accuracy of the signals and the data.

At this time, the frequency-domain density configuration for PTRS between different subbands may be independent from subband to subband, for example, if the frequency-domain density of PTRS port 0 is 2 at this time, then subband 1 and subband 2 need to configure PTRS port 0 of 3 subcarriers, so that PTRS port 0 occupying 6 subcarriers needs to be configured in the bandwidths of 10 PRBs of subband 1 and subband 2, and if the PTRS port locates the first PRB at the start position of the frequency domain, PTRS port 0 is configured on the 1 st, 3 rd and 5 th PRBs of subband 1, and the 1 st, 3 rd and 5 th PRBs of subband 2, for a total of 6 PRB positions, as shown in fig. 4.

The frequency domain density of the same PTRS port among subbands configuring the same PTRS port may be jointly configured in consideration of overhead problems. Taking the above case as an example, PTRS port 0 configured on sub-band 1 and sub-band 2 occupies 6 sub-carrier positions at this time, but if the problem of sub-band 1 and sub-band 2 in the frequency domain is substantially adjacent, that is, the 5 th PRB position in subband 1 and the 1 st PRB position in subband 2 can be considered as adjacent on the physical resource configured with the PTRS port 0, then the PTRS port 0 is configured on both PRBs, which results in waste of resources, so that the frequency domain density of the same PTRS port is jointly configured between different subbands configuring the same PTRS port at this time, from the above case it can then be considered that PTRS port 0 is configured on 10 PRBs, that is, the 1 st, 3 rd, 5 th, 7 th, and 9 th PRB locations occupy 5 PRBs in total, and correspond to the 1 st, 3 rd, and 5 th PRBs of subband 1 and the 2 nd and 4 th subcarrier locations of subband 2, respectively. As shown in fig. 5.

Similarly, the power value of the PTRS at this time may be affected because the number of allocated ports in each sub-band may be different, and since the power of the PTRS is related to the number of DMRS ports (the number of layers to be transmitted) associated with each PTRS port and the number of ports of a PTRS (Physical Resource Block) in each sub-band or a PRB (Physical Resource Block), for the case of fig. 3, sub-band 1 and sub-band 3 each need to configure 1 PTRS port, and sub-band 2 needs to configure two PTRS ports, so when allocating power, sub-band 1 and sub-band 3 cannot perform power gain related to the number of PTRS ports, and sub-band 2 configures two PTRS ports, and therefore the power of each port of the PTRS may obtain a gain of 3dB due to the existence of two PTRS ports, and therefore, a PTRS power indication at a sub-band level is required.

Similarly, the association relationship between PTRS and DMRS needs to be notified through dynamic signaling, in the current protocol; for example, in uplink transmission, if several DMRS ports share 1 PTRS port, dynamic signaling is needed to indicate which DMRS port the PTRS port is associated with. For the scenario of fig. 1, a sub-band 1 corresponds to two SRI ports, and the two SRI ports indicate that 1 PTRS port is shared, so that signaling of 1bit is required to indicate which DMRS the PTRS port 0 needs to associate with. The sub-band 2 corresponds to two PTRS ports and corresponds to two SRI port serial numbers, so that no additional signaling is needed to indicate which DMRS port the PTRS is associated with, and the sub-band 3 corresponds to two SRI ports and shares the PTRS port 1, so that a dynamic signaling of 1bit is needed to indicate. Therefore, the association relationship between the PTRS port and the DMRS port in the sub-band boundary needs to be indicated.

For uplink transmission based on a non-codebook, in the same case, if 2 SRI ports are indicated at this time, and DMRS ports associated with the two SRI ports can share 1 PTRS port 0 in subband 1, while DMRS ports associated with the 2 SRI ports in subband 2 cannot share 1 PTRS port, 2 PTRS ports, that is, port 0 and port 1, need to be configured, and DMRS ports corresponding to the SRI ports in the third subband can share PTRS port 1, then the processing procedure is similar to the above-described codebook-based scenario.

When the values of M and N are the same, the base station needs to configure the relevant information of PTRS on each sub-band separately.

If the values of M and N are different, the information that a plurality of sub-bands need to be configured with 1 PTRS is represented, and the value of N is related to different PTRS configurations on different sub-bands. For example, sub-band 1 needs to configure PTRS port 0, and sub-band 2 needs to configure PTRS port 1, which are two configurations. If there is sub-band 3 with PTRS port 0 and port 1 configured, then 3 configurations can be tasked at this time. If there is sub-band 4 with the PTRS port 0 configured, then sub-band 1 and sub-band 4 are configured by the same PTRS. The result here is a value of M of 4 and N of 3. At this time, the base station is required to configure PTRS port information and sub-band identifier information as required, and send a signaling to indicate that the terminal adopts the sub-band identifier or frequency domain position configured by the same PTRS, where the signaling includes the identifier information of the sub-band.

The value of the optional N is related to the number of ports of the PTRS in the whole bandwidth, for example, two ports are configured on all subbands, then the value of N is 2, the frequency domain density of the PTRS on each subband may be configured correspondingly according to the configuration information of the subband ports, but the association relationship between the power of the PTRS and the DMRS ports of the PTRS needs additional signaling to indicate.

Example 2

And the base station informs the terminal whether the PTRS configuration of the sub-band level is supported or not through signaling. The signaling may be at least one of: RRC signaling, MAC CE, DCI signaling

In the uplink communication, the terminal reports the supported maximum number of transmission layers, and indicates the configured PTRS port sequence number through the SRI, and finally the base station determines the number of PTRS ports and the port sequence number according to some information reported by the terminal.

Assuming that the base station configures the PTRS at the sub-band level through signaling, the specific PTRS configuration, such as frequency domain density, time domain density, PTRS power, and association between the PTRS and DMRS ports, performs the sub-band level configuration.

If the base station does not perform the configuration of the PTRS of the sub-band level. At this time, it may be determined by the base station according to information such as SRI of the terminal that each sub-band uses the same PTRS port for configuration, and at this time, the base station configures the PTRS port information obtained in the SRI information for the terminal, so that the base station does not need to perform sub-band-level PTRS configuration at this time.

Even if the SRI information of the terminal indicates that the PTRS ports corresponding to SRIs between sub-bands are different, the base station may configure the number of PTRS ports according to the SRI information of the terminal. Assume that the two sub-bands of the terminal at this time are SRI port 0, SRI port 0 and SRI port 1, respectively. At this time, SRI port information for sub-band 1 corresponds to PTRS port 0, and SRI port information for sub-band 2 corresponds to PTRS port 0 and port 1. At this time, the base station may set the PTRS port configured for sub-band 2 to only configure 1 PTRS port according to the complexity of the system, and the base station may configure PTRS port 0 on the whole bandwidth of the transmission data scheduled by the terminal due to the existence of sub-band 1 supporting PTRS port 0.

For the case that SRIs among multiple sub-bands correspond to different PTRS ports, for example, in the above example, for sub-band 1 and sub-band 3, the SRIs only support 1 PTRS port, but are PTRS port 0 and PTRS port 1, at this time, if the base station configures PTRS ports for two sub-bands respectively according to signaling, it needs to configure PTRS port 0 for sub-band 1, and configure PTRS port 1 for sub-band 3. If PTRS is not configured independently for each sub-band, namely 3 sub-bands on the bandwidth of data transmission scheduled by the terminal are configured with 1 PTRS, the base station needs to indicate to configure a PTRS port 0 or a PTRS port 1 through signaling or configure a PTRS port 0 and a PTRS port 1 on all the sub-bands simultaneously; similarly, in this case, the base station may default to a PTRS configuration method, and assuming that the PTRS configures a PTRS port 0 by default, only the PTRS port 0 is configured on the sub-band 2, and the PTRS is not configured on the sub-band 3. Thus, taking the frequency domain density of the configured PTRS as an example, as shown in fig. 6:

example 3

Configuring power of a PTRS port on a sub-band scheduled by terminal data transmission;

as the SRIs of different sub-bands may be different in the bandwidth for data transmission by the terminal, and the base station may configure different PTRS ports on each sub-band, as shown in fig. 3, at this time, 3 sub-bands of the terminal are respectively configured with a PTRS port 0, a port 1, and a PTRS port 1, and since the ratio of the port power and the data power of the PTRS is related to the number of ports of the PTRS and the number of DMRS ports (or the number of layers used for transmission) associated with each PTRS, different PTRS configurations may exist for each sub-band, and therefore, power configuration of the PTRS needs to be performed on each sub-band.

At this time, the PTRS port 0 is configured in the sub-band 1, and then the power ratio of the PTRS to the data on one sub-carrier at this time is only related to the number of DMRS ports (number of data transmission layers) associated with the PTRS port 0, and if the base station is configured with two layers of data transmission associations and the PTRS port 0 at this time, then the power of the PTRS at this time is increased by 3dB compared to the data position. The same processing mode is adopted for the PTRS port 1 and the PTRS port 0 configured for the sub-band 3. For subband 2, at this time, according to the port information of the SRI of the terminal, it may be determined that, if the base station schedules 2 layers for transmission for the terminal, then 2 DMRS ports are configured to be respectively associated with PTRS port 0 and PTRS port 1, and according to the calculation method of the power ratio between the PTRS and the data, since the number of ports of the PTRS is 2 at this time, the power obtained from the number of ports of the PTRS at this time is increased by 3dB, but each PTRS port is only associated with 1 DMRS port (1-layer data transmission), so that the increase of the total transmission power of PTRS port 0 and port 1 with respect to the data portion at this time is 3 dB. The current power description for the consistency of the uplink PTRS, and whether it is a codebook-based uplink transmission mode, is also applicable to the case where the PTRS port power is configured separately on each sub-band.

Therefore, when the precoding manners used by the terminal subbands are different, that is, ports of the PTRS that need to be configured between each subband may be different, power configuration of the PTRS needs to be performed on different subbands.

Example 4

Configuring an incidence relation between a PTRS port and a DMRS port on a sub-band scheduled by terminal data transmission;

SRI information of the terminal and a supported maximum rank (number of layers), wherein the terminal indicates a port number of the PTRS according to the maximum supported number of layers and through SRI port information. The association relationship between the PTRS and the DMRS needs to be informed through dynamic signaling, and in the current protocol; for example, in uplink transmission, if several DMRS ports share 1 PTRS port, dynamic signaling is needed to indicate which DMRS port the PTRS port is associated with.

Because the maximum number of layers supported by the terminal is consistent in each sub-band, a specific sub-band indicates that the association relationship between the PTRS port and the DMRS port by using signaling of a few bits is determined by the number of the PTRS ports on each sub-band in the current protocol; for example, in uplink transmission, if several DMRS ports share 1 PTRS port, dynamic signaling is needed to indicate which DMRS port the PTRS port is associated with. For the scenario of fig. 3, subband 1 has two SRI ports, and the two SRI ports indicate that 1 PTRS port is shared, so that signaling of 1bit is required to indicate which DMRS PTRS port 0 needs to be associated with. The sub-band 2 has two PTRS ports corresponding to two SRI port serial numbers, so that no extra signaling is needed to indicate which DMRS port the PTRS is associated with, and the sub-band 3 has two SRI ports sharing the PTRS port 1, so that a 1-bit dynamic signaling is also needed to indicate. Therefore, the association relationship between the PTRS port and the DMRS port at the sub-band level needs to be indicated.

Example 5

The base station configures information of 1 PTRS for X subbands scheduled for data transmission of the terminal, wherein the information includes at least one of the following information: frequency domain density, time domain density, power, port number, incidence relation of ports and demodulation reference signal ports and the like;

wherein the X subbands have the same PTRS port configuration, wherein X is a positive integer.

And the base station performs PTRS information configuration at the PTRS port level. That is, the base station determines the relevant information for configuring the PTRS for each sub-band of the terminal according to the SRI information of the terminal and the supported maximum transmission layer number information. Still taking the case that the terminal schedules three subbands as an example, the PTRS information configured by the base station for the terminal at this time is: a PTRS port 0 is configured in subband 1, a port 0 and a port 1 are configured in subband 2, and a PTRS port 1 is configured in subband 3. If the PTRS is configured on each self-band, overhead is increased, and therefore, a plurality of sub-bands can be configured together according to the PTRS related information configured to each sub-band by the base station, as shown in fig. 7.

Fig. 7 shows a method for configuring the frequency domain densities of PTRS on the three sub-bands, where sub-bands 1 and 2 are both configured with PTRS port 0, then the base station may configure the frequency domain density of PTRS, and in this case, all sub-bands configured with PTRS port 0 receive the relevant configuration of the base station with respect to PTRS port 0, and then configure the frequency domain density of PTRS on each sub-band, that is, the PTRS ports configured with the same configuration for X sub-bands are configured with partially the same PTRS ports in X sub-bands. The same sub-band 2 and sub-band 3 are configured with the PTRS port 1 at the same time, so the base station configures the information of the PTRS port 1 on the sub-band 2 and the sub-band 3 uniformly. According to the method of fig. 7, some signaling overhead can be saved, and similarly, since the configuration of the PTRS is on the bandwidth configured on the whole PTRS port 0 or port 1, similar to fig. 5, the resource occupation of a part of the PTRS can be reduced under certain circumstances, and a part of physical resources can also be saved, thereby effectively improving the transmission efficiency. Similarly, the base station performs uniform configuration in the frequency domain section occupied by the same PTRS port, so that each sub-band can perform respective corresponding configuration according to the configuration condition of the base station, and the PTRS configurations between the sub-bands are independent from each other. The results of the configuration are shown in fig. 4.

For the above situation, for the association relationship between the PTRS port and the DRMS port, it is also necessary to configure each sub-band separately, for example, although PTRS port 0 is configured for

sub-bands

1 and 2 in fig. 7, PTRS port 1 is configured for sub-band 2 in addition to PTRS port 0, so that the indication of the association relationship between the PTRS port and the DMRS port in the two sub-bands is different at this time.

In addition to the above method, the base station may perform uniform configuration strictly according to whether the configuration of the PTRS between the subbands is completely consistent. E.g., sub-band 1 and sub-band 2 in fig. 8, are not in perfect agreement, since sub-band 2 is also configured with PTRS port 1. Therefore, the above-mentioned complete agreement means that if there is sub-band 4 and PTRS port 0 and PTRS port 1 are also configured, then the PTRS related information of sub-band 2 and sub-band 4 can be uniformly configured by the base station. The association relationship between the PTRS port and the DMRS port may also be indicated by the base station through unified dynamic signaling DCI. And the PTRS between sub-bands with different PTRS ports configured by the base station needs to perform separate configuration on each sub-band. At this time, the port indication of the PTRS, the time domain density, the frequency domain density, the power, and the association relation indication of the PTRS port and the DMRS port may be configured according to this method.

Example 6

Determining the frequency domain position of the PTRS according to the sub-band information of the terminal;

at this time, if the relevant information of the PTRS on each sub-band is configured separately, the base station may configure the initial position of the frequency domain resource occupied by the PTRS port through signaling, and each sub-band adopts the same initial position configuration of the frequency domain resource relative to the initial position of the sub-band. In downlink transmission, Resource Element (RE) or Resource Block (RB) level offset exists, so that the base station only needs to perform configuration once on the whole bandwidth of terminal data transmission scheduling, and ports corresponding to the PTRS all adopt the same offset configuration on all scheduled subbands.

In case that there may be partial subband multiplexing for different terminals, then the frequency offset configuration of PTRS is performed only on the multiplexed subbands.

Assuming that there are two terminals multiplexing part of subbands at this time as shown in fig. 9, at this time, terminal 1 occupies positions of subband 1, subband 2, and subband 3 in the frequency domain, and terminal 2 is also configured with several subbands, where the frequency domain positions of subband 2 and subband 3 of terminal 1 and the positions of subband 1 and subband 2 of terminal 2 are multiplexed, and therefore, when configuring the offset of the frequency domain resource position of the PTRS port (including the offset of the RE level and/or the RB level), the base station needs to notify the terminal through signaling to perform corresponding offset of the PTRS on the multiplexed subband.

The base station indicates the position of a subband multiplexed between users in a multi-user multiplexing scene through signaling, and the subband position can be a subband identifier (subband ID), a frequency domain position interval of the subband, a precoding mode of the subband, and the like. And the terminal can determine the frequency domain position of the PTRS of the UE on the multiplexing sub-band according to the position of the multiplexing sub-band configured by the base station and then according to the UE-ID.

Example 7

Configuration of PTRS (packet transport standard) by base station on whole bandwidth of terminal data transmission scheduling

The base station configures the PTRS on the whole bandwidth scheduled by the terminal, and configures parameters of a PTRS port, wherein the parameters comprise at least one of the following parameters: frequency domain density, time domain density, power, port number, association relationship between ports and demodulation reference signal ports, frequency domain position of phase tracking reference signals, etc., taking the configuration example of the frequency domain density, at this time, 3 subbands of the terminal are respectively configured with a PTRS port 0, a port 1 and a PTRS port 1, and for the configuration of the frequency domain density of the PTRS port 0, the terminal is configured on both subband 1 and subband 2, so the base station performs the configuration of the PTRS port 0 on the whole scheduling bandwidth, wherein the configuration parameters include the configuration of the frequency domain density, at this time, since the PTRS of subband 1 and subband 2 are configured with the PTRS port 0, the PTRS of subband 1 and subband 2 is the configuration of the PTRS port 0 on the whole bandwidth configured by the base station, and the PTRS port 0 is not configured on subband 3, but the PTRS port 0 configured by the base station is on the whole bandwidth, therefore, no data or the like is transmitted at the PRB position where PTRS port 0 configured by the base station is located and the position where the subcarrier position needs to correspond to subband 3, that is, no other reference signal or data is transmitted at the position of PTRS port 0. For PTRS port 1, the same situation applies, and after the base station configures the relevant information of PTRS port 1, it is necessary to not send any reference signal and data at the frequency domain position of PTRS port 1 indicated by the base station according to the position of PTRS port 1 at the position of sub-band 1, as shown in fig. 10.

And for the power of each PTRS port configured by the base station, the frequency domain position, the time domain density and the port number of the PTRS, and the corresponding relation between the uplink PTRS port and the DMRS port, the method is similar to the method for configuring the frequency domain density of the PTRS.

Example 8

For the configuration of the PTRS for downlink transmission, the base station configures N sets of phase tracking reference signal information on M subbands (frequency domain units).

The configuration of the downlink PTRS may indicate to the base station that the relevant PTRS information is configured on each sub-band separately, including the frequency domain density, the time domain density, the power, the number of ports, the association relationship between the ports and the demodulation reference signal ports, the frequency domain position of the phase tracking reference signal, and the like of the PTRS;

the configuration of the downlink PTRS may indicate, for the base station, that 1 PTRS set information is configured on an X subband, and at this time, port information of partially or completely identical PTRS is indicated on the X subband.

The configuration of the downlink PTRS may indicate to the base station to configure 1 PTRS set information on all subbands.

The contents of all the above examples can be embodied in the present example.

Example 9

And the base station configures the number of PTRS ports on the whole bandwidth scheduled by the terminal through signaling indication, and configures the PTRS information on the whole bandwidth according to the precoding information or SRI or TCI information of the first sub-band.

The first sub-band is a first sub-band allocated by a predefined base station; or the first sub-band is a certain sub-band indicated by the base station through signaling.

For example, in uplink transmission, if the maximum number of layers supported by the terminal feedback is 2, and if the number of PTRS ports according to the first sub-band is 2 at this time, the number of PTRS ports configured on the entire bandwidth is 2. The number of PTRS ports is 2, which means that the DMRS ports associated with each DMRS port correspond to two antenna ports or panels, respectively, and therefore the phase noise is different, that is, the DMRS port associated with PTRS port 0 corresponds to 1 antenna, and the DMRS port associated with PTRS port 1 corresponds to another antenna. The base station can configure the number of the PTRS ports on the whole bandwidth scheduled for the terminal to be 2 according to the information, that is, 2 PTRS ports are configured on each sub-band.

Assuming that DMRS port 0 and port 1 share PTRS port 0, and DMRS port 2 and port 3 share PTRS port 1, when configuring PTRS on different subbands, since a base station indicates through signaling (RRC, MAC CE, DCI) that two PTRS ports need to be configured, DMRS ports on each subband need to be respectively selected from DMRS ports associated with the two PTRS ports at this time, that is, if 2 DMRS ports need to be configured, a suitable port (which may be selected according to a precoding manner or SRI information) needs to be selected from DMRS ports sharing PTRS port 0, and another DMRS port is selected from DMRS ports sharing PTRS port 1.

Similarly, when the number of transmission layers allocated by the base station is 1, if the PTRS port configured for sub-band 1 is PTRS port 1, all sub-bands or some sub-bands need to be configured with PTRS port 1, and if some sub-bands are configured with PTRS port 1, other sub-bands do not need to be configured with relevant information of PTRS;

and the base station configures SRI information corresponding to the PTRS port for different sub-bands according to the PTRS port configuration.

As described above, when the base station needs to configure the PTRS port 1 according to the information about the first sub-band, the PTRS port 1 needs to be configured on all sub-bands, which requires all sub-bands to select and configure the DMRS port associated with the PTRS port 1. For example, if the RI is 1, the SRI port of sub-band 1 is 0, and the corresponding PTRS port 0, if SRI port 0 and port 2 are associated with PTRS port 0 at this time, the base station needs to configure DMRS ports associated with PTRS on all sub-bands according to the PTRS or SRI configuration of sub-band 1, and indicates by configuring SRI port 0 or SRI port 2.
