Description

Method and device for reporting and receiving measurement result, communication device and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a measurement result reporting method, a measurement result receiving method, a measurement result reporting apparatus, a measurement result receiving apparatus, a communications apparatus, and a computer-readable storage medium.

Background

Currently, in a DSS (Dynamic Spectrum Sharing) scenario, an LTE (Long Term Evolution) system and an NR (New Radio) system may coexist in the same Spectrum resource, which may cause interference to the NR system due to some information sent by the LTE system.

For example, when a Resource Element (RE) corresponding to a Cell-specific Reference Signal (CRS, which may also be referred to as a Cell-level Reference Signal) transmitted by an LTE system collides with an RE corresponding to a physical downlink channel in an NR system, interference may occur when the terminal receives the physical downlink channel on the collided RE, and the demodulation performance of the physical downlink channel in the NR system is reduced.

In view of the above problems, a method of performing Rate Matching (RM) according to CRS pattern may be adopted to overcome the above problems to some extent. For example, when the terminal receives the PDSCH, the network device may map the PDSCH to REs without CRS in consideration of the presence of CRS, and accordingly, the terminal detects and receives the physical downlink channel on REs that do not transmit CRS.

In some cases, for example, when a terminal is located at a boundary of multiple cells, the terminal may be interfered by CRSs sent by the multiple cells, so that rate matching needs to be performed according to CRS patterns of the multiple cells, but performing rate matching according to too many CRS patterns may severely limit the capacity of a physical downlink channel, and may also affect the performance of the NR system and the scheduling flexibility.

Fig. 1 is a schematic flowchart illustrating a method for reporting a measurement result according to an embodiment of the present disclosure. The method for reporting the measurement result shown in this embodiment may be executed by a terminal, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication devices. The terminal may communicate with network devices including, but not limited to, network devices in 4G, 5G, 6G, etc. communication systems, such as base stations, core networks, etc.

As shown in fig. 1, the method for reporting the measurement result may include the following steps:

in step S101, measuring the signal strength of a cell reference signal CRS to obtain a measurement result;

in step S102, reporting the measurement result to a network device, where the measurement result is used to assist the network device in determining a CRS pattern for rate matching by the terminal.

It should be noted that, in all embodiments of the present disclosure, the CRS includes CRS in an LTE system; the Physical Downlink Channel includes a Physical Downlink Channel in the NR system, including but not limited to a PDSCH (Physical Downlink Shared Channel). Based on the embodiment of the disclosure, the network device may determine a CRS pattern for the terminal to perform rate matching and indicate the CRS pattern to the terminal, and the terminal may perform rate matching on the PDSCH according to the CRS pattern indicated by the network device.

For a PDCCH (Physical Downlink Control Channel), the network device may perform processing in a manner of performing puncturing (puncturing) according to the CRS pattern. The determination method of the CRS pattern according to which the PDCCH is punctured is similar to the determination method of the CRS pattern according to which the PDSCH is rate matched, that is, the terminal may measure the signal strength of the CRS to obtain a measurement result, and then report the measurement result to the network device, where the measurement result is used to assist in determining the CRS pattern for puncturing the PDCCH.

In addition, the terminal and the network device in the embodiment of the present disclosure may be co-sited, and may also be non-co-sited.

In one embodiment, the terminal may measure the Signal strength of the CRS, wherein the Signal strength includes, but is not limited to, RSRP (Reference Signal Receiving Power), SINR (Signal to Interference plus Noise Ratio), and the like. And the terminal can report the measurement result to the network equipment to assist the network equipment in determining the CRS pattern of the terminal for rate matching RM.

For example, a physical downlink channel of the terminal is interfered by multiple CRS patterns, but the interference degree of each CRS pattern is different, for example, the larger the signal strength of the CRS in the RE corresponding to the CRS pattern is, the larger the interference degree to the NR signal transmission is. Therefore, the terminal can report the measurement result by measuring the signal intensity of the CRS corresponding to each CRS pattern.

According to the embodiment of the disclosure, the terminal may measure the signal strength of the CRS, and report the measurement result to the network device, so that the network device may determine, according to the measurement result, a CRS pattern with a relatively large interference degree to the physical downlink channel, and further instruct the terminal to perform RM on the CRS pattern with the large interference degree. The terminal can perform RM only for the CRS patterns with relatively large interference degree, and does not need to perform RM for the CRS patterns with relatively small interference degree, thereby reducing the number of CRS patterns that need to perform RM, alleviating the limitation on the physical downlink channel capacity, and facilitating the improvement of the performance and scheduling flexibility of the NR system.

For example, if a physical downlink channel of the terminal is interfered by the first CRS pattern and the second CRS pattern in the corresponding time-frequency domain resource, the terminal may measure the signal strength of the CRS in the RE corresponding to the first CRS pattern to obtain a first measurement result, and measure the signal strength of the CRS in the RE corresponding to the second CRS pattern to obtain a second measurement result.

The terminal may report all obtained measurement results, for example, both the first measurement result and the second measurement result are reported to the network device, and the network device determines which CRS pattern corresponding to the measurement result is a CRS pattern that requires the terminal to perform RM, for example, the network device may determine, in the received measurement results, that the CRS pattern corresponding to the measurement result whose signal strength is greater than the strength threshold is the CRS pattern that requires the terminal to perform RM;

the terminal may also analyze the measurement result, and then determine the CRS pattern expected to perform RM, for example, the measurement result may include an average value of CRS signal strengths in REs corresponding to the CRS pattern, and then the terminal may determine that the CRS pattern (relatively strong interference to the physical downlink channel) corresponding to the average value greater than the average value threshold is the CRS pattern expected to perform RM. And reporting the measurement result of the CRS pattern which is expected to perform the RM to the network equipment, wherein the network equipment can determine the CRS pattern which is expected to perform the RM by the terminal as the CRS pattern which is required to perform the RM by the terminal according to the measurement result reported by the terminal, and can also determine the CRS pattern which is required to perform the RM by the terminal according to the actual situation.

The measurement result may be the measured signal strength of the CRS, or may be CRS pattern related information that is further obtained after measuring the signal strength of the CRS and is expected to perform rate matching. For example, the network device may indicate the CRS patterns to be measured, the terminal may measure the signal strength of the CRS in the CRS patterns to be measured, the terminal may report the measured signal strength as a measurement result, may determine a signal strength average value of the CRS in each CRS pattern to be measured, and then determine an identifier of the CRS pattern to be measured corresponding to the signal strength average value greater than the strength threshold to be reported as the measurement result, where the reported identifier is expected to execute the identifier of the CRS pattern with rate matching.

In one embodiment, the method further comprises: and determining CRS patterns needing to execute rate matching according to the indication information sent by the network equipment.

For example, the network device determines, according to the measurement result reported by the terminal, that the first CRS pattern is a CRS pattern for the terminal to perform RM, and then may instruct the terminal to perform RM on the first CRS pattern through the indication information, when the terminal receives the physical downlink channel, the terminal may consider the presence of CRS in the first CRS pattern, and map the physical downlink channel to REs other than the first CRS pattern, and correspondingly, the terminal detects and receives the physical downlink channel on REs other than the first CRS pattern.

For the second CRS pattern, the terminal does not need to perform RM, and the terminal may not consider the presence of CRS in the second CRS pattern, and the network device may map the physical downlink channel to the RE corresponding to the second CRS pattern, and correspondingly, the terminal may detect and receive the physical downlink channel on the RE corresponding to the second CRS pattern.

Accordingly, when the terminal is interfered by the first CRS pattern and the second CRS pattern in the physical downlink channel, the network device may determine the first CRS pattern with relatively strong interference as the CRS pattern that needs to perform RM, and the terminal does not need to be instructed to perform RM for the second CRS pattern with relatively weak interference. Therefore, when the physical downlink channel is configured, the RE corresponding to the second CRS pattern does not need to be RM, which is beneficial to improving the capacity of the physical downlink channel and improving the performance and scheduling flexibility of the NR system.

In an embodiment, the terminal may report the measurement result carried by Uplink Control Information (UCI), channel State Information (CSI), physical Uplink Shared Channel (PUSCH), and the like to the network device, or may select to report the measurement result carried by other Information according to needs.

In one embodiment, the measuring the signal strength of the cell reference signal CRS to obtain the measurement result comprises: and measuring the signal strength of the CRS within a predetermined resource range to obtain a measurement result.

The predetermined resource range may be determined according to a protocol agreement, may be indicated by a network device, or may be determined autonomously by the terminal.

For example, when the network device indicates the resource range, the network device may indicate the resource range to the terminal through a signaling, where the network device may determine the resource range according to an actual situation, or may determine the resource range according to a measurement capability reported by the terminal.

In one embodiment, the resource range includes a time domain resource range, where signals or data other than CRS are not expected to be received or transmitted in the time domain resource range, and no signals or data may be transmitted to the network device. Correspondingly, the network device may not transmit signals or data other than the CRS to the terminal in the time domain resource range, or may not receive signals or data transmitted by the terminal. Therefore, the measurement of the CRS by the terminal in the time domain resource range is not easily interfered, and the accurate measurement result is ensured.

In one embodiment, the time domain resource range may be determined according to a predefined rule (e.g., a protocol convention) or may be indicated by the network device.

Take the determination of the time domain resource range according to the indication of the network device as an example. For example, the time domain resource range may include a time window, and the terminal may determine the time window according to the starting position and the duration indicated by the network device, or may determine the time window according to the starting position and the ending position indicated by the network device. For example, the time domain resource range may include at least one time domain unit (radio frame, subframe, slot, symbol, etc.), and the terminal may determine the time domain resource range according to a starting time domain unit indicated by the network device and the number of time domain units. The time window may be periodic or aperiodic, and may be set according to needs.

It should be noted that the resource range may include a frequency domain resource range in addition to a time domain resource range, and the frequency domain resource range may include at least one frequency domain unit (frequency band, carrier unit, partial bandwidth, etc.), for example.

As shown in fig. 2A, taking an example that a resource range includes a time window in a time domain and a partial BandWidth BWP (BandWidth Part) in a frequency domain, and a physical downlink channel is interfered by a first CRS pattern and a second CRS pattern in the BWP, a terminal may measure RSRP of a CRS in a RE corresponding to the first CRS pattern and RSRP of a CRS in a RE corresponding to the second CRS pattern in the time window and the BWP shown in fig. 2A, and report an obtained measurement result to a network device.

As shown in fig. 2B, the resource range includes a time window in the time domain, a first frequency range (e.g., BWP) within a Carrier unit CC (Component Carrier) in the frequency domain, and the time window may include three portions, where the terminal is configured to perform radio frequency tuning (RF tuning), e.g., RF tuning to a second frequency range, where the terminal measures the signal strength of the CRS, and where the terminal may perform radio frequency tuning from the second frequency range back to the first frequency range.

The terminal is interfered by the first CRS pattern in the first frequency domain and the second CRS pattern in the second frequency domain, and in the second part of the time window shown in fig. 2B, the RSRP of the CRS in the RE corresponding to the second CRS pattern may be measured, and the obtained measurement result is reported to the network device.

It should be noted that the duration for performing the measurement in the time window (the second part), and the duration for tuning the radio frequency (the first part and the third part) may be determined according to a predefined rule (e.g., a protocol convention), or may be indicated by the network device.

Fig. 3 is a schematic flow chart of another measurement result reporting method according to an embodiment of the present disclosure. As shown in fig. 3, the measuring the signal strength of the cell reference signal CRS includes:

in step S301, a CRS pattern to be detected is determined according to a signaling of the network device;

in step S302, determining resource elements RE corresponding to the CRS pattern to be detected in the predetermined resource range;

in step S303, the signal strength measured on each of the REs to obtain a measurement result.

In an embodiment, the terminal may determine, according to a CRS pattern to be measured (which may include one or more CRS patterns) indicated by the network device, that the signal strength of the CRS needs to be measured on an RE corresponding to the CRS pattern to be measured, and then may measure, within a predetermined resource range, the signal strength on the RE corresponding to the CRS pattern to be measured, so as to obtain the measurement result, and report the measurement result.

In this embodiment, the terminal may determine, according to the CRS pattern to be measured indicated by the network device, that the signal strength of the CRS needs to be measured on the RE corresponding to the CRS pattern to be measured, so that in the process of obtaining the measurement result, the RE other than the CRS pattern does not need to be measured, which is beneficial to simplifying the measurement process and saving the implementation complexity of the terminal.

Fig. 4 is a schematic flowchart illustrating another measurement result reporting method according to an embodiment of the disclosure. As shown in fig. 4, the reporting the measurement result to the network device includes:

in step S401, determining an average value of signal intensities measured on REs corresponding to each CRS pattern to be measured;

in step S402, determining a relevant identifier of the CRS pattern to be detected corresponding to the average value greater than the preset average value threshold;

in step S403, the relevant identifier is reported to the network device.

In an embodiment, after the terminal measures the signal intensity on the REs corresponding to the CRS patterns to be measured, the terminal may further calculate an average value of the signal intensities on the REs, and further determine that the CRS patterns to be measured corresponding to the average value larger than an average value threshold have relatively large interference degree on the physical downlink channel, so that the CRS patterns to be measured corresponding to the average value may be reported to the network device as the CRS patterns expected to be subjected to RM.

In order to save resources occupied by reporting, the reporting content may be simplified, that is, the measurement result or the mean value is not directly reported, but a relevant identifier of the CRS pattern to be measured corresponding to the mean value larger than the mean value threshold, for example, a serial number of the CRS pattern, an identifier of a cell corresponding to the CRS pattern, and the like, is determined, and then the determined relevant identifier is reported to the network device, and the network device may determine the CRS pattern that the terminal desires to perform RM according to the relevant identifier.

Fig. 5 is a schematic flowchart illustrating another measurement result reporting method according to an embodiment of the disclosure. As shown in fig. 5, the measuring the signal strength of the cell reference signal CRS includes:

in step S501, measuring signal strength of a received signal in REs within the predetermined resource range;

in step S502, an RE pattern composed of REs whose signal intensity is greater than a preset intensity threshold is determined;

in step S503, a matching pattern matching the RE pattern is determined in pre-stored CRS patterns;

in step S504, the measurement result is determined according to the signal strength corresponding to the RE in the matching pattern.

In an embodiment, in a case that the network device does not indicate the CRS pattern to be measured, the terminal does not know which REs need to be measured, and therefore, the signal strengths of the received signals of all REs in the predetermined resource range need to be measured, and the RE in which the signal strength is greater than the preset strength threshold is determined. Since the signal strength on these is relatively large, REs where CRS may be present.

In addition, for each port number (e.g., 1 port, 2 ports, 4 ports), the pattern of the CRS is fixed, that is, the relationship between REs used for transmitting the CRS is fixed, so the terminal may store the CRS pattern corresponding to each number of ports in advance, may form an RE pattern for REs where the CRS may exist, and then match the pre-stored CRS pattern with the RE pattern.

Then, the matching pattern matched with the RE pattern in the pre-stored CRS patterns is the CRS pattern that causes interference to the physical downlink channel, that is, the CRS pattern to be measured, so that the measurement result may be determined according to the signal strength corresponding to the RE in the matching pattern.

Accordingly, the CRS pattern to be measured can be determined under the condition that the network equipment does not indicate the CRS pattern to be measured, and then the measurement result can be determined according to the signal strength corresponding to the RE in the matching pattern and reported to the network equipment.

For example, a plurality of CRS patterns may be stored in advance, and then a matching degree of each of the stored CRS patterns with the RE pattern determined by the measurement may be determined, and the CRS pattern with the matching degree greater than the matching threshold may be used as the matching pattern.

The matching degree may be determined according to the number of overlapping REs, for example, the more the number of the overlapping REs in the REs pattern determined by the measurement is, the higher the matching degree is; the matching degree may also be determined according to the pre-stored signal strength of the REs corresponding to the CRS patterns, for example, for each pre-stored CRS pattern, the signal strength average value of the REs corresponding to the CRS pattern may be measured, and the larger the signal strength average value is, the higher the matching degree is.

It should be noted that the matching pattern may be one CRS pattern, or may be multiple CRS patterns. In addition, when the matching pattern is not determined, the terminal may not report the measurement result, or may report the measurement result, and add additional information to the measurement result, where the additional information is used to indicate that the matching pattern is not determined. The network device may selectively determine that there is no CRS pattern that requires the terminal to perform RM.

In one embodiment, the reporting of the measurement result to the network device includes: and reporting the characteristics of the matching pattern to the network equipment.

In an embodiment, the measurement result of the signal strength corresponding to the RE in the matching pattern may be directly reported to the network device, or the characteristic of the matching pattern may be determined, and then the characteristic of the matching pattern is reported to the network device, where the characteristic of the matching pattern is used to represent information of the RE corresponding to the matching pattern, including but not limited to the number of ports corresponding to the matching pattern.

In addition to the above-mentioned manner of reporting the measurement result, as shown in the following fig. 6, it may also be determined that the cell identifier corresponding to the measurement result is reported to the network device, so as to save uplink transmission resources.

Fig. 6 is a schematic flowchart illustrating another measurement result reporting method according to an embodiment of the present disclosure. As shown in fig. 6, the reporting of the measurement result to the network device includes:

in step S601, determining a mean value of signal strengths measured on REs corresponding to each matching pattern;

in step S602, a target pattern corresponding to a mean value greater than a preset mean value threshold is determined;

in step S603, a cell identifier corresponding to a CRS sequence measured in an RE of the target pattern is determined;

in step S604, the cell identifier is reported to the network device.

In an embodiment, the measurement result of the signal strength corresponding to the RE in the matching pattern may be directly reported to the network device, or the characteristic of the matching pattern may be reported, but the measurement result and the characteristic generally have a relatively large data amount, and uplink resources occupied by reporting to the network device are large, so that simplification of the reported information may be considered.

The terminal can determine the association relationship between the CRS sequences and the cell identifiers, and accordingly, the terminal can determine the cell identifier corresponding to each CRS sequence. And then the terminal can calculate an average value of the signal intensities on the REs corresponding to the matching patterns, and then determine that the interference degree of the target patterns corresponding to the average value larger than a preset average value threshold value to the physical downlink channel is relatively large, so that the target patterns can be used as CRS patterns expected to perform RM.

For example, according to the CRS sequence measured in the RE of the target pattern, a cell identifier corresponding to the CRS sequence may be determined in the association relationship, and then the cell identifier may be reported to the network device.

Since the network device stores the corresponding relationship between the cell identifier and the CRS pattern (in this embodiment, the terminal side may not store the corresponding relationship), the network device may determine the CRS pattern of the RM desired by the terminal according to the cell identifier reported by the terminal.

Fig. 7 is a schematic flow chart diagram illustrating a measurement result receiving method according to an embodiment of the present disclosure. The measurement result receiving method shown in this embodiment may be executed by a network device, the network device may be in communication with a terminal, the network device includes, but is not limited to, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication devices.

As shown in fig. 7, the measurement result receiving method may include the steps of:

in step S701, a measurement result obtained by measuring signal strength of a terminal on a cell reference signal CRS is received, where the measurement result is used to assist in determining a CRS pattern for the terminal to perform rate matching.

In one embodiment, the terminal may measure for the signal strength of the CRS, wherein the signal strength includes, but is not limited to, RSRP, SINR, etc. And the terminal can report the measurement result to the network equipment to assist the network equipment in determining the CRS pattern of the rate matching RM of the terminal.

For example, a physical downlink channel of the terminal is interfered by multiple CRS patterns, but the interference degree of each CRS pattern is different, for example, the larger the signal strength of the CRS in the RE corresponding to the CRS pattern is, the larger the interference degree on NR signal transmission is. Therefore, the terminal can report the measurement result by measuring the signal intensity of the CRS corresponding to each CRS pattern.

According to the embodiment of the disclosure, the network device may determine the CRS pattern with a relatively large interference degree on the physical downlink channel according to the measurement result obtained by measuring the signal strength of the CRS by the terminal, and further instruct the terminal to perform RM on the CRS pattern with a relatively large interference degree. Therefore, the terminal can perform RM only on the CRS patterns with relatively large interference degree, and does not need to perform RM on the CRS patterns with relatively small interference degree, so that the number of the CRS patterns needing to perform RM is reduced, the limitation on the physical downlink channel capacity is relieved, and the performance and the scheduling flexibility of an NR system are improved.

For example, if the physical downlink channel of the terminal is interfered by the first CRS pattern and the second CRS pattern in the corresponding time-frequency domain resource, the terminal may measure the signal strength of the CRS in the RE corresponding to the first CRS pattern to obtain a first measurement result, and measure the signal strength of the CRS in the RE corresponding to the second CRS pattern to obtain a second measurement result.

In one embodiment, the method further comprises: determining a CRS pattern for the terminal to perform rate matching according to the measurement result; and sending indication information to the terminal, wherein the indication information is used for indicating the CRS pattern which needs to perform rate matching.

In an embodiment, the network device may obtain the measurement result from uplink control information UCI, channel state information CSI, PUSCH, and the like sent by the terminal, and certainly, may also obtain the measurement result from other information sent by the terminal for reporting.

Fig. 8 is a schematic flow chart diagram illustrating another measurement receiving method according to an embodiment of the present disclosure. As shown in fig. 8, the method further comprises:

in step S801, a resource range for measuring the signal strength of the CRS is configured for the terminal.

In one embodiment, the network device may configure a resource range for the terminal to measure the signal strength of the CRS, and the terminal may measure the signal strength of the CRS within the resource range configured by the network device to obtain the measurement result. For example, when the network device indicates the resource range, the network device may indicate the resource range to the terminal through a signaling, where the network device may determine the resource range according to an actual situation, or may determine the resource range according to a measurement capability reported by the terminal.

In one embodiment, the resource range includes a time domain resource range, where signals or data other than CRS may not be transmitted to the terminal or may not be received. Correspondingly, it is not desirable to receive signals other than CRS or perform data transmission in the time domain resource range, and no signal or data may be transmitted to the network device. Therefore, the measurement of the CRS by the terminal in the time domain resource range is not easily interfered, and the accurate measurement result is ensured.
