Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This disclosure claims priority from Chinese Patent Application No. 202210486820.0, filed in China on May 06, 2022, the entire contents of which are incorporated herein by reference.

[Background technology]

[0002] Channel Status Information (CSI) is one of the indicators for evaluating the quality of a channel. A base station transmits a set Channel State Information Reference Signal (CSI-RS) to a User Equipment (UE), and the UE performs channel measurement and interference measurement based on the reference signal from the base station, obtains CSI, and reports it to the base station. The base station performs correlation operations for scheduling adjustment and beam management based on the CSI reported from the UE.

[0041] As shown in Fig. 2, Fig. 2 is a flowchart of a reference signal setting method according to an embodiment of the present disclosure. As shown in Fig. 2, an embodiment of the present disclosure provides a reference signal setting method for a network side device, and the method specifically includes the following steps 101:

[0042] In step 101, at least one group of reference signal resources is configured, where each group of the reference signal resources includes at least two reference signals.

[0043] It should be noted that the specific type of the reference signal is not limited herein. In this embodiment, the reference signal may be a known signal provided from a transmitting side to a receiving side for channel measurement or channel sounding. 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 Broadcast Single Frequency Network Reference Signal (MBSFN-RS). In other embodiments, the reference signal may be a Dedicated Demodulation Reference Signal (DM-RS).

[0044] It should be noted that in some embodiments, the method specifically includes the step of: setting a group of reference signal resources, and the group of reference signal resources includes at least two reference signals. It can be understood that in this embodiment, the method specifically includes setting at least two reference signals, and any two reference signals among the at least two reference signals can be regarded as a matching reference signal pair.

[0045] In another embodiment, the method specifically includes the steps of: configuring multiple groups of reference signal resources, and each group of reference signal resources includes at least two reference signals. In this embodiment, any two reference signals belonging to the same group can be regarded as a matching reference signal pair.

[0046] In specific implementation, each matching reference signal pair set by the network side device can be used by the terminal device to measure and obtain a state information based on it.

[0047] In some embodiments, configuring at least one group of reference signal resources, each of which includes at least two reference signals, may be understood as configuring at least one reference signal resource set, each of which includes a group of reference signal resources, each of which includes at least two reference signals.

[0048] In another embodiment, configuring at least one group of reference signal resources, each of which includes at least two reference signals, may be understood as configuring one reference signal resource set and dividing it into at least one group, with the reference signal resources in each group being one group of reference signal resources, and the reference signals in each group including at least two reference signals.

[0049] Compared with the method in which a base station sets a single reference signal and a UE measures and obtains CSI corresponding to a certain time point based on a single reference, in the above solution, a network side device can set at least two reference signals so that a terminal can measure channel state information within a certain period based on the two reference signals, thereby improving the measurement efficiency of channel state information, and further reducing the number of times that the reference signal is transmitted and the number of times that the reported state information is received, thereby reducing the resource overhead of the reference signal and improving the accuracy of state information feedback based on the reference signal.

[0050] Optionally, in some embodiments, the first reference signal and the second reference signal are any two of the at least two reference signals; the occupied frequency domain resources of the first reference signal are at least a portion of the occupied frequency domain resources of the second reference signal; and / or the occupied time domain resources of the first reference signal and the occupied time domain resources of the second reference signal are different; and / or 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 of the first ports.

[0051] In addition, configuring at least one group of reference signal resources may be understood as configuring at least one of time domain information, frequency domain information, and port information of a first reference signal and a second reference signal in the at least one group of reference signal resources.

[0052] In addition, the frequency domain configuration of the first reference signal and the second reference signal satisfies 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.

[0053] In addition, the frequency domain resources occupied by the first reference signal being at least a part of the frequency domain resources occupied by the second reference signal may be understood as the frequency domain resources occupied by the first reference signal being a part of the frequency domain resources occupied by the second reference signal, or the frequency domain resources occupied by the first reference signal being the same as the frequency domain resources occupied by the second reference signal.

[0054] Optionally, in some embodiments, the occupied frequency domain resources of the first reference signal and the occupied frequency domain resources of the second reference signal are the same. With the above configuration, since the occupied frequency domain resources of the first reference signal and the occupied frequency domain resources of the second reference signal are the same, the occupied frequency domain resources of the reference signal resources can be reduced.

[0055] In addition, the time domain configuration of the first reference signal and the second reference signal satisfies the condition that the time domain resource occupied by the first reference signal is different from the time domain resource occupied by the second reference signal.

[0056] In addition, the time domain resource occupied by the first reference signal being different from the time domain resource occupied by the second reference signal may be understood as the time domain resource occupied by the first reference signal being different from the time domain resource occupied by the second reference signal in different slots, or the time domain resource occupied by the first reference signal being different symbols in the same slot.

[0057] In addition, the port settings of the first reference signal and the second reference signal satisfy that each first port of the first reference signal corresponds to at least one second port of the second reference signal, and each of the second ports corresponds to one of the first ports.

[0058] When the number of first ports is equal to the number of second ports, the first ports correspond one-to-one to the second ports. When the number of first ports is greater than the number of second ports, each of the first ports corresponds to at least one of the second ports, and each of the second ports corresponds to one of the first ports. When the number of first ports is less than the number of second ports, each of the second ports corresponds to at least one of the first ports, and each of the first ports corresponds to one of the second ports.

[0059] For ease of understanding, an example will be given below. For example, in some embodiments, the number of the first ports is two, which are represented as port #10 and port #11, respectively, and the number of the second ports is four, which are represented as port #20, port #21, port #22, and port #23, respectively. In this case, 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.

[0060] For example, when port #10 corresponds to port #20 and port #21, port #11 corresponds to port #22 and port #23. When port #10 corresponds to port #21, port #11 corresponds to port #20, port #22, and port #23.

[0061] Optionally, in some embodiments, a first period and a first slot offset are set for the first reference signal, a second period and a second slot offset are set for the second reference signal, the first slot offset is smaller than the first period, and the second slot offset is smaller than the second period.

[0062] Note that when the first slot offset is greater than or equal to the first period, the number of transmissions of the first reference signal is smaller than the number of transmissions of the first reference signal when the first slot offset is smaller than the first period. Similarly, when the second slot offset is greater than or equal to the second period, the number of transmissions of the second reference signal is smaller than the number of transmissions of the second reference signal when the second slot offset is smaller than the second period.

[0063] For ease of understanding, examples are given below for explanation. Taking the first period and the first slot offset as an example, when the first period is T1 and the first slot offset is s1, the transmission times of the first reference signal are s1, T1 + s1, 2*T1 + s1, 3*T1 + s1... N*T1 + s1 respectively. When s1 < T1, the number of transmissions of the first reference signal is denoted as N. When T1 ≤ s1 < 2*T1, if the first reference signal is not transmitted before the T1 time, the number of transmissions of the first reference signal is N - 1. When 2*T1 ≤ s1 < 3*T1, if the first reference signal is not transmitted before the 2*T1 time, the number of transmissions of the first reference signal is N - 2, and so on, which will not be elaborated here.

[0064] In an embodiment of the present disclosure, the first slot offset is smaller than the first period, and the second slot offset is smaller than the second period. With the above configuration, the number of times the first reference signal and the second reference signal are transmitted in the time domain increases, thereby improving the quality of the first reference signal and the second reference signal.

[0065] Optionally, in some embodiments, the first period and the second period are the same, and the first slot offset and the second slot offset are different; Or, The first period and the second period are the same, the first slot offset and the second slot offset are the same, and the time domain resource occupied by the first reference signal and the time domain resource occupied by the second reference signal are different.

[0066] In some embodiments, the first period and the second period are the same, and the first slot offset and the second slot offset are different. With the above configuration, the first reference signal and the second reference signal transmitted at the same period are in different slots in the time domain.

[0067] In another embodiment, the first period and the second period are the same, the first slot offset and the second slot offset are the same, and the time domain resource occupied by the first reference signal and the time domain resource occupied by the second reference signal are different. With the above configuration, the first reference signal and the second reference signal transmitted at the same period can be located at different symbols in the same slot in the time domain.

[0068] In addition, the correspondence between the first period and the second period, and the first slot offset and the second slot off group are not limited to the above embodiment. In a specific implementation, under the correspondence between the first period and the second period, and the first slot offset and the second slot off group, if the first reference signal and the second reference signal transmitted in the same period do not overlap in the time domain and the separated symbols are less than a preset value, all of the correspondences fall within the protection scope of the present solution.

[0069] Optionally, in some embodiments, the at least two reference signals include a channel state information reference signal.

[0070] In this embodiment, the at least two reference signals include a CSI-RS. In some embodiments, the CSI-RS can be understood as being modified based on a CSI-RS by default in related art. In this embodiment, since the CSI-RS is modified based on a CSI-RS by default in related art, the convenience of configuring the reference signal resources is improved.

[0071] In another embodiment, the CSI-RS can be understood as a reference signal for channel measurement with a custom configuration. In this embodiment, the CSI-RS is a reference signal for channel measurement with a custom configuration, which increases the flexibility of configuring the reference signal resources.

[0072] In addition, in a specific implementation, the at least two reference signals may include a CSI-RS modified based on a CSI-RS with default settings in the related technology, and / or a reference signal for channel measurement with custom-defined settings.

[0073] Optionally, in some embodiments, the method further comprises: transmitting the at least two reference signals to a terminal device.

[0074] In this embodiment, the at least two reference signals sent by the network side equipment to the terminal equipment are at least two reference signals of at least one group of reference signal resources set in step 101. In some embodiments, after step 101, the method further includes sending the at least two reference signals to the terminal equipment.

[0075] The terminal device may receive the at least two reference signals transmitted from the network side device, and may then measure a channel based on the at least two reference signals to obtain channel state information.

[0076] In one case, the at least two reference signals may be at least two reference signals of reference signal resources of the same group. In another case, the at least two reference signals may be at least two reference signals included in reference signal resources of multiple groups, and in this case, the at least two reference signals include at least a first reference signal and a second reference signal of reference signal resources belonging to the same group.

[0077] In addition, 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 be understood as multiple pairs of reference signals, where each pair of reference signals includes a first reference signal and a second reference signal of a reference signal resource belonging to the same group.

[0078] In this case, the terminal device can calculate one piece of channel state sub-information based on each pair of reference signals, and further obtain final channel state information based on the plurality of pieces of channel state sub-information, where a specific manner in which the terminal device obtains the final channel state information based on the plurality of pieces of channel state sub-information is not limited herein.

[0079] For example, in some embodiments, the terminal device determines an average value of a plurality of pieces of channel state sub-information as the channel state information, while in other embodiments, the terminal device determines a median value of a plurality of pieces of channel state sub-information as the channel state information.

[0080] Optionally, in some embodiments, the method further comprises: The method includes receiving channel state information reported from the terminal device.

[0081] The terminal device measures and obtains the channel state information, and then reports the channel state information to the network side device. The network side device receives the channel state information reported from the terminal device.

[0082] In some embodiments, when the network side device receives the channel state information reported from the terminal device, the network side device predicts and determines scheduling information and a codebook based on the channel state information, and performs correlation processing such as scheduling for the terminal device based on the determined codebook. In some embodiments, the codebook is also called a precoding matrix.

[0083] Specifically, when the network side device receives the channel state information reported from the terminal device, the network side device calculates and predicts scheduling information and a precoding matrix within a future target time based on the channel state information reported from the terminal device.

[0084] After the network side equipment calculates and predicts the scheduling information and the precoding matrix in a future target time, during the target time, the network side equipment may not transmit the at least two reference signals to the terminal equipment, so that during the target time, the terminal equipment may not report the channel state information.

[0085] Optionally, in some embodiments, the channel state information includes Doppler information.

[0086] However, the specific content of the Doppler information is not limited herein. Optionally, in some embodiments, the Doppler information includes at least one of a Doppler spectrum, a Doppler frequency offset, and a power delay spectrum.

[0087] It can be understood that the Doppler information is determined by the terminal device based on the at least two reference signals transmitted from the network side device. A specific manner in which the terminal device determines the Doppler information based on the at least two reference signals transmitted from the network side device is not limited here.

[0088] It should be noted that in some embodiments, the channel state information is determined by the terminal device based on the at least two reference signals transmitted from the network side device. A specific manner in which the terminal device determines the channel state information based on the at least two reference signals transmitted from the network side device is not limited herein.

[0089] In addition, the channel state information includes Doppler information, and a specific method for the terminal device to report the channel state information is not limited herein. In some embodiments, the terminal device reports channel state information to the network side device, and the Doppler information is attached to the channel state information.

[0090] It is noted that in some embodiments, the channel state information is CSI, which typically includes at least one of a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Precoding Type Indicator (PTI), and a Rank Indication (RI). In one case, the CSI includes at least one of a CQI, a PMI, a PTI, a RI, and Doppler information. In another case, Doppler information can be reported as part of the PMI.

[0091] A method for configuring a reference signal applied to a network side device according to an embodiment of the present disclosure includes configuring at least one group of reference signal resources, and each group of the reference signal resources includes at least two reference signals. With the above configuration, the network side device can configure at least two reference signals so that a terminal device can measure channel state information within a certain period based on the two reference signals, thereby improving the measurement efficiency of the channel state information, and further reducing the number of times of transmitting the reference signal and the number of times of receiving the reported state information, thereby reducing the resource overhead of the reference signal and improving the accuracy of the state information feedback based on the reference signal.

[0136] For ease of understanding, the specific flow of the reference signal setting method and the status information reporting method according to the embodiment of the present disclosure will be described below with reference to specific embodiments. For ease of explanation, the following embodiments will be described with reference to the case where the reference signal is CSI-RS.

[0137] The network side device configures at least one group of CSI-RS resources. Here, the CSI-RS resources of each group include at least two CSI-RSs. In this embodiment, two groups of CSI-RS resources are configured, and each group of CSI-RS resources includes two CSI-RSs.

[0138] In this embodiment, the CSI-RS resource of the first group is denoted as CSI-RS resource 1, and the two CSI-RS included in the CSI-RS resource of the first group are denoted as CSI-RS 11 and CSI-RS 12. The CSI-RS resource of the second group is denoted as CSI-RS resource 2, and the two CSI-RS included in the CSI-RS resource of the second group are denoted as CSI-RS 21 and CSI-RS 22.

[0139] The frequency domain configuration manner of CSI-RS 11 and CSI-RS 12 is as follows: the frequency domain position of CSI-RS 11 and the frequency domain position of CSI-RS 12 are the same.

[0140] The time domain setting method of CSI-RS 11 and CSI-RS 12 is as follows: the period of CSI-RS 11 and the period of CSI-RS 12 are the same, the slot offset of CSI-RS 11 and the slot offset of CSI-RS 12 are the same, and the symbols occupied by CSI-RS 11 and CSI-RS 12 within one RB do not overlap each other.

[0141] The port setting method of CSI-RS 11 and CSI-RS 12 is as follows: In this embodiment, CSI-RS 11 has two ports, which are denoted as port #111 and port #112. CSI-RS 12 has two ports, which are denoted as port #121 and port #122. In this way, port #111 corresponds to port #121 and port #112 corresponds to port #122, or port #111 corresponds to port #122 and port #112 corresponds to port #121.

[0142] Meanwhile, the frequency domain configuration manner of CSI-RS 21 and CSI-RS 22 is as follows: the frequency domain location of CSI-RS 21 is a subset of the frequency domain location of CSI-RS 22.

[0143] The time domain setting method of CSI-RS 21 and CSI-RS 22 is as follows: the period of CSI-RS 21 and the period of CSI-RS 22 are the same, and the slot offset of CSI-RS 21 is greater than the slot offset of CSI-RS 22, so that CSI-RS 21 and CSI-RS 22 are in different slots.

[0144] The port setting method of CSI-RS 21 and CSI-RS 22 is as follows: In this embodiment, CSI-RS 21 has four ports, which are represented as port #211, port #212, port #213, and port #214. CSI-RS 22 has two ports, which are represented as port #221 and port #222. In this way, port #211 and port #212 correspond to port #221, and port #213 and port #214 correspond to port #222.

[0145] As shown in Fig. 4, the network side device transmits CSI-RS 11, CSI-RS 12, CSI-RS 21, and CSI-RS 22 to a terminal device. The terminal device receives CSI-RS 11, CSI-RS 12, CSI-RS 21, and CSI-RS 22. The terminal device can measure and obtain first sub-channel state information and first sub-Doppler information based on CSI-RS 11 and CSI-RS 12. The terminal device can measure and obtain second sub-channel state information and second sub-Doppler information based on CSI-RS 21 and CSI-RS 22.

[0146] The terminal device determines an average value of the first sub-CSI and the second sub-CSI as the final CSI, and the terminal device determines an average value of the first sub-Doppler information and the second sub-Doppler information as the final Doppler information.

[0147] It should be noted that in some embodiments, the network side device can configure only CSI-RS resource 1 or only CSI-RS resource 2. If the network side device configures only CSI-RS resource 1, the network side device transmits CSI-RS 11 and CSI-RS 12 to the terminal device, and the terminal device can measure and obtain first sub-state information and first sub-Doppler information based on CSI-RS 11 and CSI-RS 12, and the first sub-state information and the first sub-Doppler information are the state information and Doppler information that are finally reported.

[0148] Similarly, if the network side device configures only CSI-RS resource 2, the network side device transmits CSI-RS 21 and CSI-RS 22 to the terminal device, and the terminal device can measure and obtain the second sub-state information and the second sub-Doppler information based on CSI-RS 21 and CSI-RS 22, and the second sub-state information and the second sub-Doppler information become the state information and Doppler information finally reported.

[0149] The terminal device selects J Doppler domain basis vectors to construct a Doppler subspace, and calculates channel correlation coefficients on the Doppler subspace of downlink channels. The dimension of the Doppler domain basis vector is N, and J and N are both positive integers set by higher layer signaling. The terminal device reports the selected J Doppler domain basis vectors and corresponding channel correlation coefficients as part of PMI together with other CSI information to the network side device.

[0150] When the network side device receives the CIS with the Doppler information attached, the network side device calculates and predicts scheduling information and a codebook for a certain period of time in the future based on the CIS with the Doppler information attached.
