Referring to fig. 1, fig. 1 is a block diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a data transmitting device 11 and a data receiving device 12.

Wherein, the data transmission device 11 and the data reception device 12 can communicate with each other.

In practical applications, the data sending device 11 may be a terminal (may also be referred to as a User Equipment (UE), and may also be referred to as a terminal-side device), and the data receiving device 12 may be a network-side device; alternatively, the data transmitting device 11 may be a network side device, and the data receiving device 12 may be a terminal, but is not limited thereto.

The terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device. The network side device may be a base station, an Access and Mobility Management Function (AMF), a relay, an Access point, or other network elements.

For convenience of understanding, some contents related to the embodiments of the present invention are explained below:

currently, an air interface interoperation protocol between a base station and a terminal is defined, and a downlink function is mainly defined from the perspective of the base station. For the base station equipment, the downlink is processed according to the 3GPP protocol, and the uplink receiver algorithm is the key for determining the performance of the base station. Therefore, the uplink processing complexity of the base station is significantly higher than the downlink processing complexity. For the function with high computational complexity and relatively fixed algorithm processing in the uplink receiver algorithm, accelerator processing is usually adopted, and the efficiency mainly depends on accelerator hardware. The channel estimation belongs to the function with higher computational complexity and flexibility, and the optimization of the function is the key point for improving the uplink processing efficiency.

The pilot signals support a more flexible configuration than the fourth generation communication technology (4G) and the fifth generation communication technology (5G). The pilot Signal may be a Demodulation Reference Signal (DMRS), and the number and density of pilots in time and frequency domains are different in different configurations. The DMRS for 5G adopts a pilot frequency pre-design concept. That is, in each scheduling time unit, the position where the DMRS first appears should be as close to the starting point of scheduling as possible, which is beneficial to slot-based scheduling transmission. After a position of the DMRS is immediately adjacent to a Physical Downlink Control Channel (PDCCH) region, a preamble DMRS starts from a third or four symbols according to a position of the PDCCH. And non-slot based scheduled transmission (scheduling unit is less than one slot), the pre-DMRS starts from the first symbol of the scheduling region. The use of the pre-DMRS is beneficial for a receiving end to quickly estimate a channel and perform receiving detection, and has important effects on reducing time delay and supporting a self-contained frame structure. For a low-speed mobile scene, the pre-DMRS can obtain channel estimation performance meeting demodulation requirements with low overhead. However, the moving speed of the 5G system can reach 500km/h at most. Therefore, on the basis of the pre-DMRS, a plurality of DMRS symbols can be inserted in each scheduling interval (time slot), the single-symbol pre-DMRS symbol can be added with 1-3 additional pilot symbols, and the dual-symbol pre-DMRS can be added with 1 additional pilot symbol at most. The above configuration is indicated by control signaling.

The channel estimation in the 4G/5G system belongs to the channel estimation based on the pilot frequency, and the channel estimation algorithm based on the pilot frequency mainly solves two problems. First, how to accurately estimate the channel response at the pilot signal; secondly, after estimating the channel response at the pilot frequency, how to estimate the channel response at the non-pilot frequency is usually by interpolation. Channel estimation is used to estimate the channel conditions of the wireless air interface, and thus the complexity depends on the varying characteristics of the air interface. The closeness of the channels in the frequency domain and the time domain is usually measured by the coherence bandwidth and coherence time for the air interface variation characteristics. The coherence time can also be considered as the inverse of the maximum doppler shift, and both ways depend mainly on the definition of the coherence time threshold compared to the inverse of the maximum doppler shift.

The following describes a configuration information processing method provided by an embodiment of the present invention.

Referring to fig. 2, fig. 2 is a schematic flowchart of a configuration information processing method according to an embodiment of the present invention. The configuration information processing method shown in fig. 2 may be performed by a control function on the network side.

As shown in fig. 2, the configuration information processing method may include the steps of:

step 201, determining first information of a first object executing a first operation, where the first object is a baseband processing function of a terminal or a network side, and the first information is used to determine at least one of a time period, a start time, and an execution duration;

in this embodiment of the present invention, the baseband processing function may be a partial function of a base station, the control function may be an independent network-side device, or may be a partial function in a network-side device, and when the control function is a partial function of a network-side device, the control function and the baseband processing function belong to different functions of the same network-side device.

Optionally, the time period is used to represent a time period or a time interval for performing the first operation, for example, the first object performs the first operation once every preset time period. The start-up time is used to characterize a starting instant at which the first object performs the first operation in the first time period or in each time period. The execution time duration may characterize a duration of time for which the first operation is executed once by the first object.

It should be noted that the first information determined by the control function includes one or more parameters, each of which is used for determining one of the time period, the starting time and the execution duration, and the determination content of different parameters is different. It should be understood that different terminals may be configured to perform the first operation or perform the operation related to the first operation at different time points through the first information, so as to avoid different terminals from concentrating data transmission with the network-side device, and therefore, the requirement of the network-side device for processing resources may be reduced.

Step 202, determining first configuration information of the first operation according to the first information;

In the embodiment of the present invention, the first configuration information may only include the first information, or may include other configurations besides the first information, and the other configurations may be determined based on the first information. It should be noted that the division of the terminal groups may be performed based on the network slice, that is, the terminals belonging to the same group may be associated by the network slice identifier.

It will be appreciated that one control function may manage one or more baseband processing functions, each of which is associated with one or more cells, for managing baseband processing for all terminals within the associated cell. In the embodiment of the present invention, the determined first configuration information may be multiple, where the rank of the second object associated with each first configuration information may be the same or different. In other words, the plurality of first information that the control function may transmit at one time may include first information associated with all terminals in the L1 cell and first information associated with a plurality of terminals in the L2 cell, where L1 and L2 may be positive integers, and any one of the L1 cells is not included in the L2 cell.

For example, in some embodiments, the plurality of first configuration information may satisfy at least one of:

associating all terminals in the M1 cell with M1 pieces of first configuration information;

the method comprises the steps that M2 pieces of first configuration information are contained to be associated with all terminals in M2 terminal groups;

containing M3 first configuration information associated with M3 independent terminals.

The M1, the M2, and the M3 are all positive integers, so that the first configuration information of the first operation can be flexibly set according to a cell level or a terminal level, so as to avoid data transmission with a network side device in a centralized manner by terminals in different cells or the same cell, thereby reducing a requirement of the network side device on processing resources.

Optionally, in some embodiments, the first operation may include at least one of: channel estimation, Physical Uplink Control Channel (PUCCH) processing, and hybrid automatic repeat request acknowledgement (harq) processing.

In this embodiment of the present invention, when the first object is the baseband processing function, the channel estimation may be understood as uplink channel estimation, that is, a terminal sends a reference signal, and the baseband processing function on the network side performs channel estimation based on the reference signal; the above PUCCH processing may be understood as operations such as scheduling and receiving of the PUCCH; the above-mentioned Hybrid automatic repeat request acknowledgement (HARQ-ACK) process may be understood as a related operation of transmitting HARQ-ACK to the terminal.

When the first object is a terminal, the channel estimation can be understood as downlink channel estimation, that is, a reference signal is sent by a baseband processing function on the network side, and the terminal performs channel estimation based on the reference signal; the above PUCCH processing may be understood as a related operation of transmitting PUCCH to a baseband processing function on the network side. The HARQ-ACK processing may be understood as a related operation of sending HARQ-ACK to a baseband processing function on the network side.

Optionally, in some embodiments, when the first operation includes the channel estimation, the first configuration information further includes a demodulation Reference Signal (DMRS) configuration and/or a Sounding Reference Signal (SRS) configuration.

In the embodiment of the present invention, the DMRS configuration and/or SRS configuration may be determined based on the first information. This may allow for optimization of the DMRS configuration and SRS configuration, for example, different DMRS densities or SRS densities may be used according to the duration and/or time period for performing the first operation, so as to optimize the performance of the channel estimation.

Further, in some embodiments, the first configuration information further includes a channel estimation algorithm configuration, where the channel estimation algorithm configuration includes at least two channel estimation algorithms, different channel estimation algorithms correspond to different air interface channel levels, and the air interface channel level is determined by at least one of an air interface state and a performance requirement.

In the embodiment of the invention, the channel estimation algorithm comprises two parts, wherein the first part is a channel estimation algorithm at the DMRS, the second part is a difference algorithm, and the channel estimation algorithm can be selected according to different air interface channel levels with the help of a control function. Channel estimation algorithms at DMRS, for example, typically include Least Squares (LS) algorithms and Minimum Mean Square Error (MMSE) algorithms, as well as modifications and combining schemes based on these two algorithms. In general, in the case of high signal-to-noise ratio, the LS algorithm has low computational complexity and good performance. However, when the signal-to-noise ratio is low, the complexity of the MMSE algorithm is high, but the performance is good. For the interpolation algorithm, two dimensions of frequency domain interpolation and time domain interpolation are generally included, and the time domain interpolation and the frequency domain interpolation can also be carried out simultaneously. The simplest algorithm is to directly copy the result on the DMRS without interpolation; and secondly, the interpolation algorithm also comprises linear interpolation and wiener coefficient interpolation, and the linear interpolation is simple, but the performance is poor under the condition of poor correlation. Wiener interpolation has high calculation complexity but better performance. Thus, the channel estimation control unit may divide the algorithm into different levels.

Optionally, the ranking may be performed based on at least one of the signal-to-noise ratio, the performance requirement of the cell, and the performance requirement of the terminal, for example, the ranking may be performed based on the signal-to-noise ratio according to the good and the medium differences, and the ranking may be performed based on the good and the medium differences, or the UE performance requirement may be performed based on the high, the medium, and the low, and each ranking corresponds to a channel estimation algorithm. Taking the performance of the terminal as an example, when there are no requirements for high rate and low latency for some terminals and the spectrum resources are abundant, a channel estimation algorithm with lower complexity may be adopted, and the base station may configure a lower Modulation and Coding Scheme (MCS) for the terminal, thereby reducing the requirement for the channel estimation performance.

Suppose that the air interface channel level includes level 1 and level 2, the algorithm corresponding to level 1 indicates high complexity, the algorithm corresponding to level 2 indicates low complexity, and the signal-to-noise ratio or the performance requirement of the cell/UE is graded.

The above air interface state may be understood as a cell-level or user-level radio air interface condition, and the above performance requirement may be understood as a performance requirement of a cell or a performance requirement of a terminal. In the embodiment of the invention, the grade division can be carried out based on the wireless air interface condition and the performance requirement, and different grades correspond to different channel estimation algorithms, so that the algorithm grade which meets the performance and is properly complex can be selected based on the wireless air interface condition and the performance requirement, and the optimization of channel estimation is realized.

Optionally, in some embodiments, when the first operation includes the PUCCH processing, the first configuration information further includes a PUCCH format configuration;

and/or the presence of a gas in the gas,

the first configuration information includes configuration of the number of hybrid automatic repeat request processes and configuration of hybrid automatic repeat request scheduling when the hybrid automatic repeat request response is processed.

It should be noted that, in the embodiment of the present invention, a plurality of multiple cells may be pooled, so that the multiple cells/terminals reuse baseband processing resources. Optionally, when at least two of the second objects multiplex baseband processing resources, the first configuration information corresponding to the at least two second objects satisfies at least one of the following:

the time periods of the at least two second objects are the same, and the effective times of the corresponding first configuration information are different.

For example, in some embodiments, where the first operation is channel estimation, the channel estimation satisfies at least one of:

the time periods of the channel estimation corresponding to different cells are the same, and the starting time of the channel estimation is different;

the time periods of channel estimation corresponding to all terminals in the same cell are the same, and the starting time of the channel estimation is different;

the starting time of channel estimation is the same as the effective starting time of the first DMRS configuration;

the execution duration of the channel estimation is the same as the effective duration of the first DMRS configuration;

a time period of channel estimation is the same as a time period of the first DMRS configuration;

wherein the first configuration information includes a first DMRS configuration and a second DMRS configuration, the DMRS density of the first DMRS configuration being greater than the DMRS density of the second DMRS, only the first DMRS configuration or the second DMRS configuration being in effect at any one time within a time period of the first DMRS.

In this embodiment of the present invention, when the first operation is channel estimation, the execution duration may be understood as a time length of channel estimation, the starting time may be understood as a channel estimation starting time, and the time period may be understood as a time interval of channel estimation. The effective time of the DMRS high-density configuration of a channel estimation cell level or a terminal level is consistent with the starting time of channel estimation, correspondingly, the effective time length of the DMRS configuration is the same as the time length of the channel estimation, and the time period of the DMRS configuration is the same as the time interval of the channel estimation; the effective time of the cell-level or user-level DMRS low-density configuration is equal to the starting time of channel estimation plus the time length of channel estimation, correspondingly, the effective time length of the DMRS configuration is equal to the time interval of channel estimation-the time length of channel estimation, and the time period of the DMRS configuration is the same as the time interval of channel estimation.

For example, in some embodiments, the time periods of DMRS configurations of terminals or terminal groups in a single cell or multiple cells are the same, the effective time of the DMRS configurations is different, and two sets of high-density and low-density DMRS parameter configurations are used, for example, for high-density DMRS configuration information, the time period is 10ms, the effective time is 1ms, 2 … … 9ms, and 10ms, respectively, according to the terminal or terminal group, and the effective time length is 1 ms; for the low-density DMRS configuration information, the time period is 10ms, the effective time is 2, 3 … … 10 and 1ms respectively according to the terminal or the terminal group, and the effective time length is 9 ms. In the embodiment of the invention, the DMRS configuration can be optimized, so that the performance of channel estimation can be realized.

The embodiment of the invention enables the related processing of different cells/terminal groups/terminals to reuse the same baseband processing resource in a time division manner as much as possible by pooling configuration processing time intervals and different processing starting time of the multiple cells, and avoids the phenomenon that the baseband processing resource required by a large number of cells/terminals is overlarge during the service peak value and is idle during the non-peak value due to channel estimation, PUCCH and ACK/NACK processing at the same time.

Optionally, in some embodiments, in a case that the second object is the N terminal groups, the determining first information that the first object performs the first operation includes:

acquiring target parameters of the N terminals, wherein the target parameters comprise at least one of mobility characteristic parameters and performance requirement parameters;

and determining first information of the first operation according to the target parameter.

In an embodiment of the present invention, the mobility characteristic parameter includes at least one of: the mobile speed estimation value, the maximum multipath time delay estimation value, the channel estimation value, the signal-to-noise ratio, the mobile speed truth value and the coverage scene of the cell. The performance requirement parameter comprises at least one of: cell load information, guaranteed bit rate bearer information and traffic for a cell, non-guaranteed bit rate bearer information and traffic for a cell, rate guarantee requirements, and delay requirements.

Alternatively, the estimated moving speed, the estimated maximum multipath delay value, the estimated channel value and the snr can be understood as mobility parameters of the terminal existing in the base station, and the real moving speed value and the coverage scenario of the cell can be understood as mobility parameters of the enhanced terminal. The coverage scenes of the cell may include coverage scenes such as office buildings, sports grounds, high-speed rails and the like.

It should be noted that, after the step of determining the first configuration information of the first operation according to the first information, the method further includes:

when the first object is the baseband processing unit, sending first configuration information of the first operation to the baseband processing unit;

or, when the first object is a terminal, the first configuration information is sent to the N terminals through the baseband processing unit.

In this embodiment of the present invention, the control function may communicate with the baseband processing unit, send the first configuration information to the baseband processing function, and then execute a corresponding operation by the baseband processing function.

For example, in some embodiments, when the first object is a baseband processing function, if the first configuration information includes other configurations besides the first information, the other configurations may be understood as other relevant configurations (for example, reference signal configurations) for performing the first operation, and the baseband processing function may send the other configurations to the terminal; if the first configuration information only includes the first information, the baseband processing function may determine, according to the first information, other relevant configurations for performing the first operation, and then send the other relevant configurations for performing the first operation to the terminal.

In some embodiments, when the first object is a terminal, the baseband processing function may send the first configuration to the terminal, and it should be noted that, when the first configuration information only includes the first information, the baseband processing function may determine, according to the first information, other relevant configurations for performing the first operation, and then send the other relevant configurations for performing the first operation and the first information to the terminal.

For better understanding of the present invention, the following will describe the implementation of the present invention in detail by taking channel estimation as an example.

Embodiment 1, channel estimation time interval optimization scheme.

Traditionally, the baseband processing at the network side is driven with a strict timing design, and in order to ensure a definite and uniform timing, the baseband processing at each slot (slot) of a cell is the same. A common configuration in current networks is a subcarrier spacing of 20kHz with 2 slots in a 1ms subframe. For 2.6GHz frequency, only under the condition that the UE speed is up to 350km/h in a high-speed railway scenario, the coherence time of an air interface channel is about 0.5ms, and each time slot is required to perform channel estimation in the scenario. For other scenarios, for example, when the user moving speed is 4km/h, the coherence time of the air interface channel is about 42 ms. Then, there is a configuration space for how often channel estimation is performed in time, so the time interval for configuring channel estimation may be optimized in the embodiment of the present invention, specifically, as shown in table one below, the channel estimation time interval configuration may be cell level or UE level, a cell coverage scenario mainly oriented to a cell is relatively single for the cell level configuration, and a UE level configuration may configure a certain UE or a certain group of UEs in a certain cell. And the time point of uplink channel estimation of a certain cell/UE can be configured.

Table one:

optionally, in some embodiments, a certain UE or a certain UE group may be configured to perform uplink channel estimation (i.e. transmit a corresponding reference signal) once every 40ms, and the time point for performing uplink channel estimation is the first time slot of every 40 ms. The base station uplink processing is processed in parallel according to the UE as a basic unit, and different UEs do not perform uplink channel estimation at the same time point through configuration, so that the complexity of the cell channel estimation can be reduced, and the requirement on processing resources is reduced. With respect to generation of the time interval configuration parameter, the channel estimation control unit may obtain a maximum coherence time from parameters existing in the base station, such as a user moving speed estimation value and a carrier frequency, thereby generating a channel estimation time interval configuration parameter. Or according to the analysis of the historical channel estimation value, the change of the channel estimation result in a certain period of time is little, thereby generating the channel estimation time interval configuration parameter. Or obtaining the maximum coherence time according to the user moving speed truth value provided by the outside and the carrier frequency known by the base station, and obtaining the time interval configuration parameter. Or according to an externally provided coverage scene, obtaining a typical channel change situation of the scene, and also obtaining a time interval configuration parameter.

Optionally, in some embodiments, a certain cell may be configured to perform uplink channel estimation every 10ms (or every 10 subframes or 20 timeslots), and a time point of performing uplink channel estimation is a first timeslot of every 10 ms. Consider a single baseband board supporting multiple cells, or a general CPU platform based base station solution where a single CPU or server may support multiple cells. Compared with the single base station scheme, in the single base station scheme, an operator purchases the base station capability based on the highest requirement, and the pooling mode can save the base station operation resource by increasing the number of terminals served simultaneously (terminal aggregation effect). When the channel estimation control unit configures that the uplink channel estimation time intervals of different cells are the same, and the time points of uplink channel estimation performed by different cells are different. For example, the time point of channel estimation performed by the a cell is the first slot of each 10ms, the time point of channel estimation performed by the B cell is the third slot of each 10ms, and so on. Then, a design scheme for pooling baseband resources is no longer to fix the processing resources of each cell in the traditional baseband board design scheme, but multiple cells share the same processing resources in the baseband board or in the server, thereby achieving the purpose of pooling baseband resources, reducing the overall processing resource demand and reducing the cost.

Embodiment two, an optimization scheme of DMRS configuration.

The baseband processing of the traditional network side is driven by strict time sequence design, in order to ensure the definite and uniform time sequence, the existing configuration is a uniform scheme of the whole network seen from the mobile phone terminal side, two symbols DMRS are configured in each time slot, and are distributed on every other RE on the frequency domain. However, for a high-speed rail scene, the requirement on the configuration density of the DMRS is higher, so that a more complex channel estimation algorithm is supported, and the uplink receiving performance is improved. For a scene that most terminals in the room are static, if the time domain DMRS interpolation is not needed, only one preamble DMRS is configured, and the frequency domain interval may be larger. Therefore, the channel estimation control unit may perform optimal configuration on the parameters of the DMRS according to different scenarios or mobility information of the terminal, where the configuration channel may include information in table two below, where table two is merely an example, and may further include more configuration information in other embodiments, which is not listed here. When the DMRS configuration optimization is used in cooperation with the scheme in embodiment 1, a DMRS with a higher density is configured in the time for performing channel estimation in embodiment 1, and a DMRS with the lowest density is configured in an interval period, thereby saving pilot overhead and improving spectral efficiency.

Table two:

and in the third embodiment, the optimization scheme of the channel estimation algorithm.

The traditional channel estimation algorithm comprises two parts, wherein the first part is a channel estimation algorithm at the DMRS, the second part is a difference algorithm, and the channel estimation algorithm can be selected according to different air interface channel levels with the assistance of a control function. Channel estimation algorithms at, for example, DMRS, typically include Least Squares (LS) algorithms and Minimum Mean Square Error (MMSE) algorithms, as well as improvements and combining schemes based on both algorithms. In general, in the case of high signal-to-noise ratio, the LS algorithm has low computational complexity and good performance. However, when the signal-to-noise ratio is low, the complexity of the MMSE algorithm is high, but the performance is good. For the interpolation algorithm, two dimensions of frequency domain interpolation and time domain interpolation are generally included, and the time domain interpolation and the frequency domain interpolation can also be carried out simultaneously. The simplest algorithm is to directly copy the result on the DMRS without interpolation; and secondly, the interpolation algorithm also comprises linear interpolation and wiener coefficient interpolation, and the linear interpolation is simple, but the performance is poor under the condition of poor correlation. Wiener interpolation has high calculation complexity but better performance. Thus, the channel estimation control unit may divide the algorithm into different levels. The rank 1 algorithm represents high complexity, the rank 2 algorithm represents low complexity, and ranks the signal-to-noise ratio or the performance requirements of the cell/UE. For example, the signal-to-noise ratio can be divided into three levels of 0-10dB,10-20dB and 20-30dB according to the good and the medium difference points, or the UE performance requirements can be divided into high, medium and low. For some UEs without high rate and low latency requirements and with abundant spectrum resources, the base station may configure the UE with a lower uplink MCS, thereby reducing the requirement for channel estimation performance. The configuration information of channel estimation in the embodiment of the present invention is shown in table three below.

Table three:

it should be noted that, in the information in the tables one to three, a certain configuration list may be selected from all the parameters for use as needed.

Optionally, the control function may be an enhanced function inside the base station, or may also support all or part of the control function on a Near-real-time wireless intelligent controller (Near-RT RIC) or a network manager. When the Near-RT RIC supports the CONTROL function, the E2 interface may add the configuration field in the Information Element (IE) definition of the CONTROL or POLICY (CONTROL) through the flow of the CONTROL or POLICY (POLICY). When the network management configuration supports the control function, the data model of the management surface of the enhanced base station can support the cell level parameter configuration.
