[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202210486820.0 filed in China on May 6, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of wireless technology, and in particular to a reference signal configuration method, a status information reporting method, and related devices. Background Art

[0004] Channel Status Information (CSI) is a measure of channel quality. The base station sends a configured Channel State Information Reference Signal (CSI-RS) to the user equipment (UE). The UE then performs channel and interference measurements based on the reference signal sent by the base station, obtains CSI, and reports it to the base station. The base station then uses the CSI reported by the UE to adjust scheduling and perform beam management.

[0005] In medium- and high-speed mobility scenarios, channel conditions often change rapidly. Therefore, the UE needs to frequently report CSI to the base station so that the base station can adjust scheduling and manage beams based on the current channel conditions. However, current reference signal configuration and transmission methods result in low CSI measurement efficiency.

[0076] Referring to Figure 2, Figure 2 is a flowchart of a reference signal configuration method provided by an embodiment of the present disclosure. As shown in Figure 2, an embodiment of the present disclosure provides a reference signal configuration method, which is applied to a network-side device. The method specifically includes the following steps:

[0077] Step 101: configure at least one group of reference signal resources, each group of reference signal resources including at least two reference signals.

[0078] It should be understood that the specific type of the reference signal is not limited here. In this embodiment, the reference information may refer to a known signal provided by the transmitting end to the receiving end for channel estimation or channel detection. The reference signal may be an uplink reference signal or a downlink reference signal. For example, in some embodiments, the reference signal may be a channel state information reference signal (CSI-RS). In other embodiments, the reference signal may be a multicast / multicast single frequency network reference signal (MBSFN-RS). In other embodiments, the reference signal may be a dedicated demodulation reference signal (DM-RS).

[0079] It should be understood that in some embodiments, the method specifically includes the following steps: configuring a set of reference signal resources, where the set of reference signal resources includes at least two reference signals. In this embodiment, it can be understood that the method specifically includes configuring the at least two reference signals, and any two of the at least two reference signals can be considered a matched reference signal pair.

[0080] In some other embodiments, the method specifically includes the following steps: configuring multiple groups of reference signal resources, each group of reference signal resources including at least two reference signals. In this embodiment, any two reference signals belonging to the same group can be considered as a matching reference signal pair.

[0081] In a specific implementation, each matching reference signal pair configured by the network-side device can be used to enable the terminal device to obtain status information based on its measurement.

[0082] In some embodiments, configuring at least one group of reference signal resources, each group of reference signal resources including at least two reference signals can be understood as configuring at least one reference signal resource set, wherein each reference signal resource set includes one group of reference signal resources, and the group of reference signals includes at least two reference signals.

[0083] In other embodiments, configuring at least one group of reference signal resources, each group of reference signal resources including at least two reference signals can be understood as configuring one reference signal resource set and dividing it into at least one group, the reference signal resources in each group being one group of reference signal resources, and each group of reference signal resources including at least two reference signals.

[0084] Compared with the method in which the base station configures a single reference signal and enables the UE to obtain the CSI corresponding to a certain moment based on a single reference measurement, in the above scheme, the network-side device configures at least two reference signals so that the terminal can measure the channel state information within a period of time based on the two reference signals, thereby improving the efficiency of channel state information measurement, thereby reducing the number of times the reference signal is sent and the number of times the reported state information is received, thereby reducing the resource overhead of the reference signal and providing the possibility of improving the accuracy of the reference signal state information feedback.

[0085] Optionally, in some embodiments, the first reference signal and the second reference signal are any two reference signals among the at least two reference signals;

[0086] The frequency domain resources occupied by the first reference signal are at least a part of the frequency domain resources occupied by the second reference signal; and / or,

[0087] The time domain resources occupied by the first reference signal and the time domain resources occupied by the second reference signal are different; and / or,

[0088] Each first port of the first reference signal corresponds to at least one second port of the second reference signal, and each second port corresponds to one first port.

[0089] It should be understood that configuring at least one group of reference signal resources may be understood as configuring at least one of the following of the first reference signal and the second reference signal in the at least one group of reference signal resources: port information of time domain information and frequency domain information.

[0090] It should be understood that the frequency domain configuration of the first reference signal and the second reference signal satisfies the following: the frequency domain resources occupied by the first reference signal are at least a part of the frequency domain resources occupied by the second reference signal.

[0091] It should be understood that the frequency domain resources occupied by the first reference signal are at least a part of the frequency domain resources occupied by the second reference signal. It can be understood that the frequency domain resources occupied by the first reference signal are a part of the frequency domain resources occupied by the second reference signal, or the frequency domain resources occupied by the first reference signal are the same as the frequency domain resources occupied by the second reference signal.

[0092] Optionally, in some embodiments, the frequency domain resources occupied by the first reference signal and the frequency domain resources occupied by the second reference signal are the same. Through the above configuration, since the frequency domain resources occupied by the first reference signal and the frequency domain resources occupied by the second reference signal are the same, the frequency domain resources occupied by the reference signal resources can be reduced.

[0093] It should be understood that the time domain configuration of the first reference signal and the second reference signal satisfies the following: the time domain resources occupied by the first reference signal are different from the time domain resources occupied by the second reference signal.

[0094] It should be understood that the time domain resources occupied by the first reference signal and the time domain resources occupied by the second reference signal are different, which can be understood as that the time domain resources occupied by the first reference signal and the time domain resources occupied by the second reference signal are different time slots, or the time domain resources occupied by the first reference signal and the time domain resources occupied by the second reference signal are different symbols within the same slot.

[0095] It should be understood that the port configuration of the first reference signal and the second reference signal satisfies the following: each first port of the first reference signal corresponds to at least one second port of the second reference signal, and each second port corresponds to one first port.

[0096] It should be understood that when the number of first ports is equal to the number of second ports, the first ports correspond one-to-one with the second ports. When the number of first ports is greater than the number of second ports, each first port corresponds to at least one second port, and each second port corresponds to one first port. When the number of first ports is less than the number of second ports, each second port corresponds to at least one first port, and each first port corresponds to one second port.

[0097] For ease of understanding, the following examples illustrate this. For example, in some embodiments, there are two first ports, designated as port #10 and port #11, and four second ports, designated as port #20, port #21, port #22, and port #23. Port #10 can correspond to one to three ports among port #20, port #21, port #22, and port #23, and port #11 can correspond to the remaining one to three ports.

[0098] For example, if port #10 corresponds to port #20 and port #21, port #11 corresponds to port #22 and port #23. If port #10 corresponds to port #21, port #11 corresponds to port #20, port #22, and port #23.

[0099] Optionally, in some embodiments, the first reference signal is configured with a first period and a first slot offset, and the second reference signal is configured with a second period and a second slot offset, the first slot offset is smaller than the first period, and the second slot offset is smaller than the second period.

[0100] It should be understood that, when the first time slot offset is greater than or equal to the first period, the number of times the first reference signal is transmitted will be less than the number of times the first reference signal is transmitted when the first time slot offset is less than the first period. Similarly, when the second time slot offset is greater than or equal to the second period, the number of times the second reference signal is transmitted will be less than the number of times the second reference signal is transmitted when the second time slot offset is less than the second period.

[0101] For ease of understanding, the following example illustrates the first period and the first time slot offset. The first period is denoted as T1, and the first time slot offset is denoted as s1. The times at which the first reference signal is sent are s1, T1+s1, 2*T1+s1, 3*T1+s1, and N*T1+s1, respectively. When s1 < T1, the number of times the first reference signal is sent is N. When T1 ≤ s1 < 2*T1, the first reference signal is not sent before time T1, and the number of times the first reference signal is sent is N-1. When 2*T1 ≤ s1 < 3*T1, the first reference signal is not sent before time 2*T1, and the number of times the first reference signal is sent is N-2. The same applies and will not be described in detail here.

[0102] In an embodiment of the present disclosure, the first time slot offset is smaller than the first period, and the second time slot offset is smaller than the second period. Through the above settings, the first reference signal and the second reference signal can be sent more times in the time domain, thereby improving the quality of the first reference signal and the second reference signal.

[0103] Optionally, in some embodiments, the first period and the second period are the same, and the first time slot offset and the second time slot offset are different;

[0104] or,

[0105] The first period and the second period are the same, the first time slot offset and the second time slot offset are the same, and the first reference signal and the second reference signal occupy different time domain resources.

[0106] It should be understood that in some embodiments, the first period and the second period are the same, and the first time slot offset and the second time slot offset are different. Through the above configuration, the first reference signal and the second reference signal sent in the same period are in different slots in the time domain.

[0107] It should be understood that in some other embodiments, the first period and the second period are the same, the first time slot offset and the second time slot offset are the same, and the first reference signal and the second reference signal occupy different time domain resources. Through the above configuration, the first reference signal and the second reference signal transmitted in the same period can be in different symbols of the same slot in the time domain.

[0108] It should be noted that the correspondence between the first period and the second period, and between the first time slot offset and the second time slot offset, is not limited to the examples in the above embodiment. In a specific implementation, if the correspondence between the first period and the second period, and between the first time slot offset and the second time slot offset, is such that the first reference signal and the second reference signal transmitted in the same period do not overlap in the time domain and the symbol interval is less than a preset value, then such correspondence falls within the protection scope of this solution.

[0109] Optionally, in some embodiments, the at least two reference signals include a channel state information reference signal.

[0110] In this embodiment, the at least two reference signals include CSI-RSs. In some embodiments, the CSI-RSs can be understood as being modified based on the CSI-RSs configured by default in related technologies. In this embodiment, since the CSI-RSs are modified based on the CSI-RSs configured by default in related technologies, the convenience of configuring the reference signal resources is improved.

[0111] In other embodiments, the CSI-RS may be understood as a custom-configured reference signal for channel measurement. In this embodiment, since the CSI-RS is a custom-configured reference signal for channel measurement, the flexibility of configuring the reference signal resource is improved.

[0112] It should be understood that, in a specific implementation, the at least two reference signals may include a CSI-RS modified based on a default configured CSI-RS in related technologies, and / or a custom configured reference signal for channel measurement.

[0113] Optionally, in some embodiments, the method further comprises:

[0114] The at least two reference signals are sent to the terminal device.

[0115] In this embodiment, the at least two reference signals sent by the network side device to the terminal device are at least two reference signals included in at least one group of reference signal resources configured in step 101. In some embodiments, after step 101, the method further includes sending the at least two reference signals to the terminal device.

[0116] The terminal device may receive the at least two reference signals sent by the network side device. Then, the terminal device may measure a channel based on the at least two reference signals to obtain channel state information.

[0117] It should be understood that, in one case, the at least two reference signals may be at least two reference signals included in the same group of reference signal resources. In another case, the at least two reference signals may also be at least two reference signals included in multiple groups of reference signal resources. In this case, the at least two reference signals include at least a first reference signal and a second reference signal belonging to the same group of reference signal resources.

[0118] It should be understood that, when the at least two reference signals are at least two reference signals included in multiple groups of reference signal resources, the at least two reference signals can also be understood as multiple pairs of reference signals, each pair of reference signals including a first reference signal and a second reference signal belonging to the same group of reference signal resources.

[0119] In this case, the terminal device may calculate a channel state sub-information based on each pair of reference signals, and then obtain final channel state information based on the multiple channel state sub-information. The specific manner in which the terminal device obtains the final channel state information based on the multiple channel state sub-information is not limited herein.

[0120] For example, in some embodiments, the terminal device determines an average value of multiple channel state sub-information as the channel state information. In other embodiments, the terminal device determines a median value of multiple channel state sub-information as the channel state information.

[0121] Optionally, in some embodiments, the method further comprises:

[0122] Receive channel state information reported by the terminal device.

[0123] After obtaining the channel state information through measurement, the terminal device reports the channel state information to the network side device. The network side device receives the channel state information reported by the terminal device.

[0124] In some embodiments, after receiving the channel state information reported by the terminal device, the network-side device determines scheduling information and a codebook based on the channel state information prediction, and performs related processing such as scheduling on the terminal device according to the determined codebook. In some embodiments, the codebook may also be referred to as a precoding matrix.

[0125] Specifically, after receiving the channel state information reported by the terminal device, the network side device will calculate and predict the scheduling information and precoding matrix within the future target time length based on the channel state information reported by the terminal device.

[0126] After the network side device calculates and predicts the scheduling information and precoding matrix within the future target time length, the network side device may not send the at least two reference signals to the terminal device within the target time length. Therefore, the terminal device may not report the channel state information within the target time length.

[0127] Optionally, in some embodiments, the channel state information includes Doppler information.

[0128] It should be understood that the specific content of the Doppler information is not limited herein. Optionally, in some embodiments, the Doppler information includes at least one of the following: a Doppler spectrum, a Doppler frequency offset, and a power delay spectrum.

[0129] It should be understood that the Doppler information can be understood as being determined by the terminal device based on the at least two reference signals sent by the network side device. The specific manner in which the terminal device determines the Doppler information based on the at least two reference signals sent by the network side device is not limited herein.

[0130] It should be understood that, in some embodiments, the channel state information is determined by the terminal device based on the at least two reference signals sent by the network-side device. The specific manner in which the terminal device determines the channel state information based on the at least two reference signals sent by the network-side device is not limited herein.

[0131] It should be understood that the channel state information includes Doppler information, and the specific method for the terminal device to report the channel state information is not limited here. In some embodiments, the terminal device reports the channel state information to the network side device, and the channel state information carries the Doppler information.

[0132] It should be understood that in some embodiments, the channel state information is CSI. Typically, CSI includes at least one of the following: Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), Precoding Type Indicator (PTI), and Rank Indication (RI). In one case, the CSI includes at least one of the following: CQI, PMI, PTI, RI, and Doppler information. In another case, Doppler information can be reported as part of PMI.

[0133] The reference signal configuration method provided in the embodiments of the present disclosure, applied to a network-side device, includes configuring at least one group of reference signal resources, each group of reference signal resources including at least two reference signals. Through this configuration, the network-side device can configure at least two reference signals, so that a terminal device can measure channel state information over a period of time based on the two reference signals, thereby improving the efficiency of channel state information measurement, thereby reducing the number of reference signal transmissions and the number of reported state information receptions, thereby reducing reference signal resource overhead and potentially improving the accuracy of reference signal-based state information feedback.

[0134] 3 , which is a flow chart of a method for reporting status information provided by an embodiment of the present disclosure, including the following steps:

[0135] Step 201: Receive at least two reference signals.

[0188] In this embodiment, the first group of CSI-RS resources is recorded as CSI-RS resource 1, and the two CSI-RSs included therein are recorded as CSI-RS 11 and CSI-RS 12. The second group of CSI-RS resources is recorded as CSI-RS resource 2, and the two CSI-RSs included therein are recorded as CSI-RS 21 and CSI-RS 22.

[0189] On the one hand, the frequency domain configuration of CSI-RS 11 and CSI-RS 12 is as follows: the frequency domain position of CSI-RS 11 is the same as the frequency domain position of CSI-RS 12.

[0190] The time domain configuration of CSI-RS 11 and CSI-RS 12 is as follows: the period of CSI-RS 11 is the same as the period of CSI-RS 12, the time slot offset of CSI-RS 11 is the same as the time slot offset of CSI-RS 12, and the symbols occupied by CSI-RS 11 and CSI-RS 12 within one RB do not overlap.

The terminal device may measure and obtain first sub-state information and first sub-Doppler information based on CSI-RS 11 and CSI-RS 12. The first sub-state information and first sub-Doppler information are the final reported state information and Doppler information.

[0198] Similarly, when the network side device is only configured with CSI-RS resource 2, the network side device sends CSI-RS 21 and CSI-RS 22 to the terminal device. The terminal device can measure the second sub-state information and the second sub-Doppler information based on CSI-RS 21 and CSI-RS 22. The second sub-state information and the second sub-Doppler information are the final reported state information and Doppler information.

The terminal device selects J Doppler domain basis vectors and the corresponding channel correlation coefficient as part of the PMI and reports them to the network-side device together with other CSI information.
