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

As can be seen from Information theory, accurate Channel State Information (CSI) is crucial to Channel capacity. Especially for a multi-antenna system, the transmitting end can optimize the transmission of the signal according to the CSI, so that the transmitting end can be more matched with the state of the channel. Such as: a Channel Quality Indicator (CQI) may be used to select a suitable Modulation and Coding Scheme (MCS) to implement link adaptation; precoding Matrix Indicator (PMI) can be used to implement eigen-beamforming (eigen-beamforming) to maximize the strength of a received signal, or to suppress interference (e.g., inter-cell interference, inter-user interference, etc.). Therefore, since the Multi-antenna technology (MIMO) has been proposed, CSI acquisition has been a research focus.

Generally, CSI acquisition is mainly divided into two ways: one is explicit feedback, such as feedback of CQI, PMI, etc.; the other is implicit feedback, such as using channel reciprocity. For large-scale antenna array system (massive MIMO), implicit feedback based on channel reciprocity is favored because the number of antennas is large and the resource overhead of explicit feedback is large.

However, when only partial reciprocity exists in uplink and downlink channels, the existing scheme for CSI acquisition does not consider the timing offset at the terminal side, so that the result of channel estimation is inaccurate.

The transmission processing method provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

As shown in fig. 2, a transmission processing method according to an embodiment of the present application includes:

in step 201, a terminal receives a channel state information reference signal CSI-RS.

Here, the terminal receives the CSI-RS, and thus can perform channel state estimation based on the CSI-RS, thereby completing reception of a signal.

Step 202, the terminal processes signals on the ports of the CSI-RS according to the specific port information,

wherein the specific port information includes at least one of:

power strength sequence of ports;

delay skew relationship of ports.

Here, the terminal knows the power strength sequence of the ports and/or the delay deviation relationship of the ports. After receiving the CSI-RS in step 201, executing this step can process the signal received at each CSI-RS port according to the specific port information, and obtain a more accurate channel estimation result with less implementation complexity and calculation overhead, thereby implementing effective signal reception and CSI calculation.

The processing of the signals includes processes of timing calibration, channel estimation, CSI calculation, and the like, wherein according to the power strength sequence of the ports and/or the delay offset relationship of the ports, the timing calibration can be performed on all the ports, and also on part of the ports, so that under the condition of smaller implementation complexity and calculation overhead, more accurate channel estimation results are obtained, and effective signal reception and CSI calculation are realized.

Optionally, step 202 comprises:

the terminal carries out 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 is a different port from the second port. The timing deviation obtained by timing calibration of the first port is shared by the second port, and the timing calibration of the second port is not needed, so that 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, and may also be another port. Therefore, optionally, before the terminal performs timing calibration on the first port, the method further includes:

the terminal determines the first port in the ports of the CSI-RS according to the specific port information; or,

the terminal takes a target port as the first port, the target port is a port of a Tracking Reference Signal (TRS), a Phase-Tracking Reference Signal (PTRS), a Demodulation Reference Signal (DMRS) or a Synchronization Signal 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 in this case, the first port may be all ports or a part of ports of the CSI-RS in one-time configuration.

Alternatively, the first port is a port for another signal, and the other signal is a TRS, a PTRS, a DMRS, or an SSB. The resource of the second port needs to be quasi co-located with the resource of the first port, so that the timing deviation obtained by timing calibration of the first port can be shared by the second port.

Optionally, in an aspect, in this embodiment, the determining, according to the specific port information, the first port in a port of a CSI-RS includes:

if the specific port information includes a power strength order of the ports, determining that the first port includes: among the ports of the CSI-RS, N1 ports with stronger power, wherein N1 is an integer greater than or equal to 1.

Here, the power strength order of the ports is used for the network side device to map the CSI-RS ports and transmit the CSI-RS. For the case that the specific port information includes the power strength order of the ports, the terminal can select N1 ports with stronger power, i.e., the port 0 to the port N1-1, from the ports of the CSI-RS based on the power strength order of the ports. Wherein, N1 may be equal to the number of ports of all CSI-RSs, and may be less than the number of ports of all CSI-RSs. And the power of other ports except the N1 ports in the ports of the CSI-RS is lower than that of the N1 ports.

For example, for all 8 CSI-RS ports, based on the power strength order of the ports, the first 3 CSI-RS ports with stronger power among the 8 CSI-RS ports may be selected for timing calibration. The power of the remaining 5 CSI-RS ports is less than the power of the 3 CSI-RS ports.

Optionally, in another aspect, in this embodiment, the determining, by the terminal, the first port in a port of a CSI-RS according to the specific port information includes:

if the specific port information includes a delay offset relationship of ports, and the delay offset relationship indicates that timing offsets 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 ports, or at least one of the fourth ports.

Here, the delay skew relationship indicates whether or not the timing skew between ports is the same among the ports of the CSI-RS. In the case where the specific port information includes a delay skew relationship of the ports, the terminal can determine the first port among the ports of the CSI-RS indicated by the delay skew relationship based on the port having the same timing skew among the ports.

The timing offset relationship here 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 the timing calibration is performed on one CSI-RS resource, the other CSI-RS resources may use the same result.

For another example, if the timing offset on each polarization is assumed to be the same, all ports on the first polarization are used as the first port, timing calibration is performed and timing error is calculated, and then all ports on the second polarization use the same calculation result.

For example, for all 8 ports of the CSI-RS, the delay skew relationship of the ports indicates that the timing skew of the ports 1 to 4 (third ports) and the ports 5 to 8 (fourth ports) is the same, and based on the delay skew relationship of the ports, if the ports 1 to 4 of the CSI-RS are selected as the first ports, the ports 1 to 4 of the CSI-RS are subjected to timing calibration and calculated to obtain the timing skew, and the ports 5 to 8 of the CSI-RS may use the same timing skew.

For a first port determined among ports of a CSI-RS, optionally, the second port includes other ports than the first port among the ports of the CSI-RS.

For example, in all the 8 ports of the CSI-RS, based on the power strength order of the ports, the port of 3 CSI-RS with stronger power among the 8 ports of the CSI-RS is selected as the first port, and timing calibration is performed thereon. Then, the remaining 5 CSI-RS ports are the second ports, and the positioning offset obtained by performing the positioning calibration on the first port can be shared without performing the timing calibration.

For another example, for all 8 ports of the CSI-RS, the delay offset relationship of the port indicates that the timing offsets of the ports 1 to 4 (third port) and the ports 5 to 8 (fourth port) are the same, and based on the delay offset relationship of the port, if the port 1 of the CSI-RS is selected as the first port, the timing calibration is performed on the port 1 of the CSI-RS. Then, the ports 2 to 8 of the CSI-RS are selected as the second port, and the positioning offset obtained by the positioning calibration on the port 1 of the CSI-RS can be shared without performing the timing calibration.

Optionally, the CSI-RS resource corresponding to the third port is different from the CSI-RS resource corresponding to the fourth port; 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 offsets of the ports corresponding to different CSI-RS resources are the same, or may indicate that the timing offsets of the ports corresponding to different CSI report configurations are the same.

In this way, if a plurality of CSI-RS resources are configured in the CSI report configuration (CSI report config), and one of the CSI-RS resources corresponds to the first port, the ports corresponding to the other CSI-RS resources in the CSI-RS resources are the second ports, and the timing offset is shared.

In this embodiment, optionally, the number of ports included in resourcemaping of the CSI-RS resource corresponding to the second port is equal to the number of ports included in resourcemaping of the CSI-RS resource corresponding to the first port.

Specifically, if the CSI-RS resource (resource a) in the CSI report config corresponds to the first port, the number of ports included in the resourcemaping of the CSI-RS resource (resource B) in the subsequent CSI report config is the same as the number of ports included in the resourcemaping of the resource a, and the CSI report configuration shares the timing offset.

In addition, in this embodiment, the first port is determined by the port with the same timing offset indicated by the delay offset relationship, which may be autonomously selected by the terminal or according to the convention with the network side device, for example, the third port is used as the first port, or the fourth port is used as the first port; or the network side equipment can indicate. Optionally, the first port is indicated by a first indication signaling of the network side device.

In this way, for a third port and a fourth port with the same timing offset in the ports of the CSI-RS indicated by the delay offset relationship, the first indication signaling indicates that one or more of the third ports are the first port, or indicates that one or more of the fourth ports are the first port.

Optionally, the first indication signaling comprises at least one of:

a CSI-RS port identification;

a CSI-RS resource identification;

and CSI report configuration identification.

For example, when 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 at least one of the identification of the fourth port.

When the first indication signaling comprises a CSI-RS resource identifier (CSI-RS resource ID), the CSI-RS resource indicated by the CSI-RS resource identifier is the CSI-RS resource corresponding to the first port. At this time, the CSI-RS port identifier is at least one of the CSI-RS resource identifiers corresponding to the third port or the CSI-RS resource identifiers corresponding to the fourth port.

When the first indication signaling includes 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 a CSI-RS resource corresponding to the first terminal. Here, the target CSI-RS resource may be a specific CSI-RS resource (e.g., the first CSI-RS resource) in the CSI reporting configuration indicated by the CSI reporting configuration identifier, or a predetermined CSI-RS resource indicated by the CSI-RS resource identifier, or all CSI-RS resources.

In addition, in this embodiment, optionally, when the first port is the target port, the first port is indicated by a second indication signaling of a network side device.

Optionally, the second indication signaling comprises at least one of:

transmitting a configuration indication (TCI) status identifier;

a CSI reporting configuration identity.

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.

And when the second indication signaling comprises CSI report configId, the terminal finds a signal of which the resource is quasi-co-located with the target CSI-RS resource in the CSI report config indicated by the CSI report configId, and carries out timing calibration on the 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 identifier, or a CSI-RS resource indicated by a predetermined CSI-RS resource identifier, or all CSI-RS resources.

Optionally, in this embodiment, the terminal performs timing calibration on the first port, and after obtaining the timing offset, the method further includes:

and the terminal adjusts the channel estimation related information of the CSI-RS according to the timing deviation.

In this way, the terminal performs channel estimation according to the adjusted channel estimation related information, and can achieve more effective signal reception after channel estimation, for example, by performing PMI calculation.

Optionally, the channel estimation related information includes:

a particular latency location;

the delay position 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, and so on. For example, the network side device encodes all delay paths to a fixed delay position through cyclic delay diversity CDD, where the delay position is a specific delay position.

The window/set indicated by the network side device may be a distribution window/set of the delay paths, and 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 within the window/set, or the like.

And for the time delay position, the terminal adjusts the time delay position according to the timing deviation, and then the PMI calculates the position adjusted based on the time delay position.

The application of the method of the embodiment of the present application is described below with reference to specific scenarios:

in a first scenario, it is assumed that a network side device configures multiple CSI-RS resources in one CSI report config, the CSI-RS resources may correspond to different PMIs, or the multiple CSI-RS resources may be associated to the same PMI, a terminal performs timing calibration only on a first or a certain CSI-RS resource, calculates a timing offset, and corrects delay positions of paths on ports corresponding to all the CSI-RS resources according to the timing offset, thereby calculating a 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 appoints the CSI-RS resource1 as the resource corresponding to the port of the timing calibration, the terminal carries out the timing calibration on the resource by using the corresponding 8 CSI-RS ports, and the timing deviation delta is calculated.

Therefore, channels estimated on 24 CSI-RS ports on two resources are corrected, namely, each CSI-RS port is weighted according to a DFT vector corresponding to delta on each PRB estimated channel, namely

Wherein H_tdIs an estimated time domain channel, N_PRBIs the number of PRBs, j is the imaginary symbol, H_iIs the frequency domain channel on the ith PRB.

And a second scenario is that the network side equipment performs channel estimation according to the uplink channel SRS, calculates a downlink CSI-RS decoder according to partial reciprocity, and maps each column of CSI-RS decoders with CSI-RS ports according to the sequence of the power factors from large to small.

And the network side equipment indicates 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 indication of the network side equipment. When the terminal performs timing calibration (i.e. searches for a position with a delay of 0), the first ports are selected for timing calibration to obtain timing offset, and the timing offsets of all CSI-RS ports are considered to be the same, so as to perform timing calibration on signals received by each port.

Specifically, the network side device obtains uplink channel information according to the uplink SRS information, and calculates to obtain 32 SD-FD pairs, that is, space-frequency domain joint coding. Mapping the 32 SD-FD pairs onto port 0 to port 31 according to the power from large to small, wherein the specific power P_iThe calculation method comprises the following steps:

wherein N is_RIs the number of ports of the SRS,

where Precode (i) denotes the ith column of the calculated CSI-RS Precoder. H_SRSIs root ofAccording to the channel estimated by the uplink SRS,

is the equivalent channel after CSI-RS precoding.

After the terminal receives the CSI-RS, the first 4 ports are selected for timing calibration, namely, the power time delay spectrums of the first four ports are added, and the time delay tau corresponding to the maximum power is found₀(i.e., timing offset), this delay is defined as delay 0.

The terminal calculates the time delay tau according to₀And performing time delay compensation on all ports, and then performing CSI calculation.

And a third scenario that the network side equipment indicates a plurality of CSI report configs, and the terminal performs timing calibration on the first CSI report config for each CSI-RS resource to obtain a corresponding timing deviation.

And in each subsequent CSI report config, the terminal searches the CSI-RS resource with the same port number in the first CSI report config according to the port number in the resource mapping in the CSI-RS resource, and compensates each CSI-RS port on the current CSI-RS resource by using the timing error calculated in the CSI-RS resource.

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 the UE share the timing offset before the next indication or configuration.

In summary, in the method of the embodiment of the present application, the terminal performs timing calibration on all or part of ports of the CSI-RS, or performs timing calibration by using other signal ports instead of ports of the CSI-RS, so as to suppress performance loss caused by timing offset, improve CSI measurement accuracy, avoid reporting a result of timing calibration to the network side device, reduce overhead, and avoid accuracy loss. Moreover, the result of timing calibration can be shared, thereby improving the flexibility and reducing the complexity.
