Description

Transmission processing method, terminal and network side equipment
Technical Field
The application belongs to the technical field of communication, and particularly relates to a transmission processing method, a terminal and network side equipment.
Background
From the theory of Information, accurate Channel State Information (CSI) is critical to channel capacity. Especially for multi-antenna systems, the transmitting end can optimize the transmission of the signal according to the CSI so that it more matches the state of the channel. Such as: channel quality indication (Channel Quality Indicator, CQI) may be used to select an appropriate modulation coding scheme (Modulation and Coding Scheme, MCS) for link adaptation; the precoding matrix indicator (Precoding Matrix Indicator, PMI) may be used to implement eigenbeamforming (eigen beamforming) to maximize the strength of the received signal or to suppress interference (e.g., inter-cell interference, inter-user interference, etc.). Thus, CSI acquisition has been a research hotspot since Multi-antenna technology (MIMO) was proposed.
In general, CSI acquisition is largely divided into two ways: one is explicit feedback, such as feedback of CQI, PMI, etc.; the other is implicit feedback, such as exploiting channel reciprocity, etc. For large-scale antenna array systems (massive MIMO), implicit feedback based on channel reciprocity is favored because of the large resource overhead of explicit feedback due to the large number of antennas.
However, in the case where only partial reciprocity exists in the uplink and downlink channels, timing deviation at the terminal side is not considered in the existing scheme for CSI acquisition, so that the result of channel estimation is inaccurate.

The transmission processing method provided by the embodiment of the application is described in detail below by means of some embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in fig. 2, a transmission processing method according to an embodiment of the present application includes:
In step 201, the terminal receives a channel state information reference signal CSI-RS.
Here, the terminal will receive the CSI-RS, so that channel state estimation can be performed based on the CSI-RS, and signal reception is completed.
Step 202, the terminal processes signals according to specific port information on ports of CSI-RS,
Wherein the specific port information includes at least one of:
the power intensity sequence of the ports;
delay offset relationship of ports.
Here, the terminal is a known power order of ports and/or a delay deviation relation of ports. After receiving the CSI-RS in step 201, the present step is performed, so that the signal received on each CSI-RS port can be processed according to the specific port information, and a more accurate channel estimation result can be obtained with smaller implementation complexity and calculation overhead, thereby realizing effective signal reception and CSI calculation.
The processing signal comprises timing calibration, channel estimation, CSI calculation and other processes, wherein according to the power strength sequence of the ports and/or the time delay deviation relation of the ports, not only can the timing calibration be carried out on all ports, but also the timing calibration can be carried out on part of ports, so that more accurate channel estimation results are obtained under the condition of lower implementation complexity and calculation cost, and effective signal receiving and CSI calculation are realized.
Optionally, step 202 includes:
the terminal performs timing calibration on the first port to obtain timing deviation;
and the terminal shares the timing deviation to a second port according to the specific port information.
Here, the second port is a port of the CSI-RS, and the first port and the second port are different ports. And the timing deviation obtained by timing calibration of the first port is shared to the second port, so that the timing calibration of the second port is not needed, and a complex processing flow is avoided.
It should be appreciated that in this embodiment, the first port may be a port of the CSI-RS, or may be another port. Therefore, optionally, before the timing calibration on the first port, the terminal further includes:
The terminal determines the first port in the ports of the CSI-RS according to the specific port information; or alternatively
The terminal takes a target port as the first port, wherein the target port is a port of a tracking reference signal (TRACKING REFERENCE SIGNAL, TRS), a Phase-tracking reference signal (Phase-TRACKING REFERENCE SIGNAL, PTRS), a Demodulation reference signal (Demodulation REFERENCE SIGNAL, DMRS) or a Synchronization signal block (Synchronization SIGNAL AND PBCH block, SSB), and the resource of the target port is quasi co-located with the resource of the second port.
That is, the first port is determined among ports of the CSI-RS based on specific port information known to the terminal, and may be all ports or part ports of the CSI-RS in one configuration.
Still alternatively, the first port is a port for other signals, either TRS, PTRS, DMRS or SSB. The resources of the second port need to be quasi co-located with the resources of the first port to ensure that the timing deviation obtained by the timing calibration of the first port can be shared to the second port.
Optionally, in an aspect, in this embodiment, the determining, according to the specific port information, the first port in ports of the CSI-RS includes:
if the specific port information includes the power strength sequence of the ports, determining that the first port includes: among the ports of the CSI-RS, N1 ports with stronger power are provided, and N1 is an integer greater than or equal to 1.
Here, the power strength sequence of the ports is used for mapping the CSI-RS ports by the network side device and transmitting the CSI-RS. For the case that the specific port information includes the power strength sequence of the ports, the terminal can select N1 ports with stronger power in the ports of the CSI-RS, that is, ports 0 to N1-1, based on the power strength sequence of the ports. Wherein, N1 may be equal to the number of ports of all CSI-RS, and may be less than the number of ports of all CSI-RS. And the powers of the ports of the CSI-RS except the N1 ports are lower than the powers of the N1 ports.
For example, ports of all 8 CSI-RS may be selected for timing calibration based on the power order of the ports, and the ports of the first 3 CSI-RS with higher power among the ports of the 8 CSI-RS may be selected for timing calibration. The power of the ports of the remaining 5 CSI-RSs is less than the power of the ports of the 3 CSI-RSs.
Optionally, on the other hand, in this embodiment, the determining, by the terminal, the first port in ports of the CSI-RS according to the specific port information includes:
If the specific port information includes a delay deviation relation of ports and the delay deviation relation indicates that timing deviations of a third port and a fourth port in the ports of the CSI-RS are the same, determining that the first port includes: at least one of the third port or at least one of the fourth port.
Here, the delay offset relationship indicates whether timing offsets among ports of the CSI-RS are the same. In the case that the specific port information includes a delay offset relation of ports, the terminal can determine a first port among ports of CSI-RS indicated by the delay offset relation based on the ports having the same timing offset among the ports.
The timing offset relationship may be configured by the base station through RRC, or may be agreed, for example, it is agreed that the timing offsets of multiple CSI-RS resources in the same CSI report config are the same, that is, as long as timing calibration is performed on one of the CSI-RS resources, the other CSI-RS resources may use the same result.
For another example, it is agreed that the timing deviation on each polarization is the same, and when all ports on the first polarization are used as the first ports, timing calibration is performed and timing errors are calculated, all ports on the second polarization use the same calculation result.
For example, the delay deviation relationship of all ports of 8 CSI-RS indicates that the timing deviation of ports 1-4 (third port) and ports 5-8 (fourth port) is the same, and based on the delay deviation relationship of the ports, if port 1-4 of CSI-RS is selected as the first port, the timing deviation is calculated by performing timing calibration on port 1-4 of CSI-RS, and the ports 5-8 of CSI-RS can use the same timing deviation.
Optionally, for the first port determined in the ports of the CSI-RS, the second port includes other ports than the first port among ports of the CSI-RS.
For example, on all ports of 8 CSI-RS, based on the power order of the ports, the port of 3 CSI-RS with stronger power among the ports of the 8 CSI-RS is selected as the first port, and timing calibration is performed thereon. The remaining ports of the 5 CSI-RSs are the second ports, and the positioning offset obtained by performing positioning calibration on the first port can be shared without performing timing calibration.
For another example, the delay deviation relationship of all ports of the 8 CSI-RS indicates that the timing deviations of ports 1-4 (third port) and ports 5-8 (fourth port) are the same, and based on the delay deviation relationship of the ports, if port 1 of the CSI-RS is selected as the first port, timing calibration is performed on port 1 of the CSI-RS. And selecting ports 2-8 of the CSI-RS as a second port, and sharing the positioning deviation obtained by positioning calibration on port 1 of the CSI-RS without timing calibration.
Optionally, the CSI-RS resource corresponding to the third port and the CSI-RS resource corresponding to the fourth port are different; or, the CSI report configuration corresponding to the third port is different from the CSI report configuration corresponding to the fourth port.
That is, the delay offset relationship may indicate that the timing offset of ports corresponding to different CSI-RS resources is the same, or may indicate that the timing offset of ports corresponding to different CSI reporting configurations is the same.
Thus, if multiple CSI-RS resources are configured in the CSI reporting configuration (CSI report config), and one CSI-RS resource in the multiple CSI-RS resources corresponds to the first port, the port corresponding to the other CSI-RS resource in the multiple CSI-RS resources is the second port, and the timing offset is shared.
In this embodiment, optionally, the number of ports included in resourceMapping of the CSI-RS resource corresponding to the second port is equal to the number of ports included in resourceMapping of the CSI-RS resource corresponding to the first port.
Specifically, if the CSI-RS resource (resource a) corresponds to the first port in CSI report config, then in the subsequent step CSI report config, the number of ports included in resourceMapping of the CSI-RS resource (resource B) is the same as the number of ports included in resourceMapping of the resource a, and the timing offset is shared.
In addition, in this embodiment, the first port is determined by the port with the same timing deviation indicated by the delay deviation relationship, which may be selected by the terminal autonomously or according to a convention with the network side device, for example, the third port is taken as the first port, or the fourth port is taken as the first port; or may be indicated by the network side device. Optionally, the first port is indicated by a first indication signaling of the network side device.
Thus, for the third port and the fourth port with the same timing deviation in the ports of the CSI-RS indicated by the delay deviation relation, the first indication signaling indicates that one or more ports in the third port are the first ports, or indicates that one or more ports in the fourth port are the first ports.
Optionally, the first indication signaling includes at least one of:
CSI-RS port identification;
CSI-RS resource identification;
CSI reporting configuration identification.
If the first indication signaling includes a CSI-RS port identifier, the port indicated by the CSI-RS port identifier is the first port. At this time, the CSI-RS port identification is at least one of the identification of the third port or the identification of the fourth port.
When the first indication signaling includes a CSI-RS resource identifier (CSI-RS resourceID), the CSI-RS resource indicated by the CSI-RS resource identifier is a CSI-RS resource corresponding to the first port. At this time, the CSI-RS port identifier is at least one of CSI-RS resource identifiers corresponding to the third port or at least one of CSI-RS resource identifiers corresponding to the fourth port.
When the first indication signaling comprises a CSI report configuration identifier (CSI report configID), in the CSI report configuration indicated by the CSI report configuration identifier, the target CSI-RS resource is the CSI-RS resource corresponding to the first terminal. Here, the target CSI-RS resource may be a specific CSI-RS resource (e.g., a first CSI-RS resource) in the CSI reporting configuration indicated by the CSI reporting configuration identification, or a CSI-RS resource indicated by the predetermined CSI-RS resource identification, or all CSI-RS resources.
In addition, in this embodiment, optionally, in a case where the first port is the target port, the first port is indicated by second indication signaling of the network side device.
Optionally, the second indication signaling includes at least one of:
transmitting a configuration indication TCI state identifier;
CSI reporting configuration identification.
Thus, when the second indication signaling includes a TCI status identifier (TCI-stateId), the terminal finds a signal corresponding to the TCI-stateId, such as TRSP, TRS, DMRS or SSB, and performs timing calibration on a port of the signal.
When the second indication signaling includes CSI report configId, the terminal finds out a signal of which the resource is quasi co-located with the target CSI-RS resource in CSI report config indicated by CSI report configId, and performs timing calibration on a port of the signal. Here, the target CSI-RS resource may be a specific CSI-RS resource (e.g., a first CSI-RS resource) in the CSI reporting configuration indicated by the CSI reporting configuration identification, or a CSI-RS resource indicated by the predetermined CSI-RS resource identification, or all CSI-RS resources.
Optionally, in this embodiment, after performing timing calibration on the first port by the terminal to obtain the timing deviation, the method further includes:
And the terminal adjusts the channel estimation related information of the CSI-RS according to the timing deviation.
Thus, the terminal performs channel estimation according to the adjusted channel estimation related information, such as performing PMI calculation, and more effective signal reception can be realized after channel estimation.
Optionally, the channel estimation related information includes:
a specific delay position;
delay positions in the window/set indicated by the network side device.
The specific delay position may be a predetermined delay position, such as a position of delay 0, a position of delay 3, etc. For example, the network side device encodes all delay paths through cyclic delay diversity CDD to a fixed delay location, which is a particular delay location.
The window/set indicated by the network side device may be a distributed window/set of delay paths, where the delay position in the window/set may be a start position of the window/set, an end position of the window/set, a position in the window/set, and the like.
And for the time delay position, the terminal adjusts the time delay position according to the timing deviation, so that the PMI calculation can be based on the position after the time delay position is adjusted.
The application of the method according to the embodiment of the present application is described below in conjunction with a specific scenario:
In the first scenario, it is assumed that the network side device configures multiple CSI-RS resources in one CSI report config, where the CSI-RS resources may correspond to different PMIs, or the multiple CSI-RS resources may be associated to the same PMI, and the terminal performs timing calibration only on the first CSI-RS resource or one CSI-RS resource, calculates a timing deviation, corrects delay positions of paths on ports corresponding to all CSI-RS resources according to the timing deviation, and further calculates the PMI.
Specifically, as shown in fig. 3, the network side device configures CSI-RS resource1 and CSI-RS resource2, where resource1 corresponds to 8 CSI-RS ports and resource2 corresponds to 16 CSI-RS ports. The network side equipment indicates or agrees with the corresponding resource of the port with the CSI-RS resource1 as timing calibration, and the terminal performs timing calibration on the resource by using the corresponding 8 CSI-RS ports to calculate the timing deviation delta.
Thereby correcting the estimated channels on 24 CSI-RS ports on two resources, namely weighting the estimated channels of each CSI-RS port on each PRB according to DFT vectors corresponding to delta, namely
Where H td is the estimated time domain channel, N PRB is the number of PRBs, j is the imaginary symbol, and H i is the frequency domain channel on the ith PRB.
And in a second scenario, the network side equipment is assumed to perform channel estimation according to an uplink channel SRS, calculates downlink CSI-RS precoder according to partial dissimilarity, and maps each column of the CSI-RS precoder according to the sequence from the large power factor to the small power factor.
The network side equipment instructs the terminal to perform channel estimation on the corresponding CSI-RS, and the terminal finds the time-frequency position and port distribution of the corresponding CSI-RS according to the instruction of the network side equipment. When the terminal performs timing calibration (i.e. searches for a position with time delay of 0), the first ports are selected for performing timing calibration to obtain timing deviation, and the timing deviation of all CSI-RS ports is considered to be the same, so that the signals received by each port are subjected to timing calibration.
Specifically, the network side device obtains uplink channel information according to the uplink SRS information, and calculates to obtain 32 SD-FD pairs, i.e. space domain-frequency domain joint coding. Mapping the 32 SD-FD pairs to port 0 to port 31 according to the power from large to small, and specifically calculating the power P i by the following steps:
Where N R is the number of SRS ports,
Where Precoder (i) represents the i-th column of the calculated CSI-RS Precoder. H SRS is a channel estimated from the uplink SRS,Is an equivalent channel after CSI-RS precoding.
After receiving the CSI-RS, the terminal selects the first 4 ports to perform timing calibration, i.e. adds the power delay spectrums of the first four ports, finds the delay τ 0 (i.e. timing deviation) corresponding to the maximum power, and defines this delay as delay 0.
And the terminal performs delay compensation on all ports according to the calculated delay tau 0, and then performs CSI calculation.
In a third scenario, assuming that the network side device indicates multiple CSI report config, the terminal performs timing calibration on the first CSI report config for each CSI-RS resource, and obtains a corresponding timing offset.
And each subsequent CSI report config, the terminal searches for the CSI-RS resources with the same port number in the first CSI report config according to the port number in resourceMapping in the CSI-RS resources, and compensates each CSI-RS port on the current CSI-RS resources by using the timing error calculated in the CSI-RS resources.
Optionally, in this embodiment, the terminal performs timing calibration on the first port, periodically or non-periodically (triggered by the network side).
Optionally, in this embodiment, the CSI-RS measurements of this UE share this timing offset before the next indication or configuration.
In summary, according to the method provided by the embodiment of the application, the terminal performs timing calibration on all or part of ports of the CSI-RS, or uses other signal ports to replace ports of the CSI-RS to perform timing calibration, so that performance loss caused by timing deviation is restrained, the CSI measurement precision is improved, the result of timing calibration is not reported to network side equipment, the cost is reduced, and the precision loss is avoided. And the result of timing calibration can be shared, so that the flexibility is improved, and the complexity is reduced.
It should be noted that, in the transmission processing method provided in the embodiment of the present application, the execution body may be a transmission processing apparatus, or a control module in the transmission processing apparatus for executing the loading transmission processing method. In the embodiment of the present application, a transmission processing device executes a loading transmission processing method as an example, and the transmission processing method provided in the embodiment of the present application is described.

a processing module 420, configured to process signals according to specific port information on ports of the CSI-RS,
Wherein the specific port information includes at least one of:
the power intensity sequence of the ports;
delay offset relationship of ports.
According to the device, after the CSI-RS is received, signals received on each CSI-RS port can be received and processed according to specific port information on the ports of the CSI-RS, a more accurate channel estimation result is obtained, and effective signal receiving and CSI calculation are achieved. The processing signal comprises timing calibration, channel estimation, CSI calculation and other processes, wherein according to the power strength sequence of the ports and/or the time delay deviation relation of the ports, not only can the timing calibration be carried out on all ports, but also the timing calibration can be carried out on part of ports, so that more accurate channel estimation results are obtained under the condition of lower implementation complexity and calculation cost, and effective signal receiving and CSI calculation are realized.
