Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a resource configuration method, device, network equipment and terminal equipment. Background Art

[0002] The discussion on terminal energy saving in Rel-17 agreed that the base station will configure the Channel State Information Reference Signal (CSI-RS) resources configured for the terminal in the connected state to the idle / inactive mode terminal for at least the channel tracking function. Since the time when the data transmission of the user equipment (UE) in the connected state ends is random, the CSI-RS resources notified by the base station to the terminal may change frequently. At this time, once the CSI-RS resources change, the base station must reconfigure the resources through system messages. Frequent reading of system messages by the terminal will increase the power consumption of the terminal, and the energy saving gain brought by introducing CSI-RS for the idle / inactive mode terminal will be greatly discounted. At the same time, the system message overhead is too large, which also increases the terminal receiving power consumption. More importantly, it brings a large overhead to the base station side. Therefore, the parameter information of CSI-RS is configured for the idle / inactive mode terminal through the system information block (SIB) message.

[0003] If the parameter configuration of the existing connected CSI-RS / (Tracking Reference Signal, TRS) is fully reused, the upper limit of the maximum information carrying capacity of the SIB message will be exceeded, which is 2976 bits (372 bytes). If the configured information exceeds the maximum information carrying capacity of the SIB message, the SIB message will be further divided and transmitted through multiple physical downlink shared channels (Physical Downlink Shared Channel, PDSCH). For the terminal, it is necessary to receive multiple PDSCHs to obtain the SIB message, which will increase the time to obtain the SIB message. Once a bit error occurs in one of the SIB messages (the bit error rate is 10%), more time will be required, which will cause the terminal to generate higher latency and power consumption when receiving the SIB message. Summary of the invention

[0004] The embodiments of the present invention provide a resource configuration method, apparatus, network equipment and terminal equipment to solve the problem that the prior art fails to configure parameter information of reference signals for idle / inactive mode terminals to achieve energy saving and reduce system overhead.

The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art can understand that the 5G NR system is only an example and is not a limitation.

[0275] See also Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied, such as Figure 1As shown, it includes a user terminal 11 and a base station 12, wherein the user terminal 11 may be a user equipment (User Equipment, UE), for example: it may be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, referred to as PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device). It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present application. The above-mentioned base station 12 may be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or referred to as a node B. It should be noted that in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0276] First, some concepts related to the embodiments of the present invention are described as follows.

[0277] 1. Paging process:

[0278] For the New Radio (NR) system, the optimization of power saving and reception robustness in the radio resource control idle (RRC_IDLE) / radio resource control inactive (RRC_Inactive) mode is also very important. For example, for low-complexity NR terminals, such as smart wearable devices or sensor devices, they mainly work in RRC_IDLE / RRC_Inactive mode, and have stricter requirements on power saving than ordinary NR terminals. For user equipment (UE) that works in RRC_IDLE / RRC_Inactive mode for a long time, the UE will receive paging and system information (SI). Unlike the Long Term Evolution (LTE) system, there is no Common Reference Signal (CRS) in the RRC_IDLE / RRC_Inactive mode for NR terminals. Therefore, before receiving the paging information at the corresponding PO (Paging Occasion), the terminal needs to first receive the synchronization signal block (Synchronization Signal Block, SSB) to perform time frequency tracking (T / F tracking) and automatic gain control (Automatic Gain Control, AGC) and other operations to improve the reception performance of Paging messages (including Paging DCI and Paging PDSCH), such as Figure 2 As shown. In order to obtain better T / F tracking performance, considering that PSS / SSS in SSB only occupies 12 PRBs, in practice, especially under low signal-to-noise ratio, multiple (such as 3) SSBs are often required to perform T / F tracking to improve the accuracy of fine synchronization. The default period of SSB in idle mode is 20ms, so the terminal often needs to wake up 60ms in advance to receive SSB, which will undoubtedly greatly increase the power consumption of the terminal. At the same time, it is also noted that if the distance between SSB and PO is far, the accuracy of time / frequency tracking will deteriorate to a certain extent. The reception performance of Paging messages, at the same time, after receiving SSB, the terminal cannot sleep to save power, which will also increase the power consumption of the terminal.

[0279] In addition to paging and SI, the future evolution of the NR standard is considering the introduction of a multimedia broadcast multicast system similar to LTE. This multimedia broadcast multicast system is sent periodically in RRC-idle mode, and the UE needs to detect the scheduling DCI first. However, since the NR system in Stand Alone (SA) networking does not have the CRS in the LTE system, its channel tracking operation is similar to paging and is based on SSB operation, so it has the same power consumption and reception accuracy problems as the paging operation. It should be further explained that the SI in NR includes the Master Information Block (MIB) and its System Information Block (SIB). The SIB is divided into SIB1 and other system information (other SIB) (the current NR protocol includes SIB2-SIB9), among which SIB1 is also called the remaining minimum system information (Remaining Minimum SI, RMSI).

[0280] 2. Existing CSI-RS configuration method:

[0281] In Active Time, the base station configures various reference signals RS (Reference Signal) for the UE for various purposes of channel quality measurement and beam management. The RS may include CSI-RS for tracking, i.e. Tracking RS (TRS). The base station configures TRS resources for the terminal, and the terminal uses the TRS configured by the base station to perform channel tracking operations; the RS may also include CSI-RS for mobility measurement, i.e. CSI-RS for mobility. The terminal uses the CSI-RS for mobility configured by the base station to perform RRM measurement operations; the RS may also include CSI-RS for channel quality and measurement reporting and its beam management.

[0282] NR Rel-15, Rel-16 protocols only allow UE-specific CSI-RS resources to be configured for terminals in RRC-connected mode through dedicated RRC signaling. The base station uses high-level signaling CSI-ResourceConfig and non-zero power CSI-RS resource sets (NZP-CSI-RS-ResourceSet) to configure one or more NZP CSI-RS resource sets for connected terminals (up to 16 NZP CSI-RS resource sets in one CSI configuration). Each resource set contains K≥1 NZP CSI-RS resources (up to 64, 128 NZP CSI-RS resources in one resource set).

[0283] The high-level parameters related to CSI-RS resources include CSI measurement configuration (CSI-MeasConfig), CSI resource coordination (CSI-ResourceConfig), NZP-CSI-RS ResourceSet, non-zero power CSI-RS resource (NZP-CSI-RSresource), and the NZP CSI-RS resource structure configured for the UE. Figure 3 shown.

[0284] The specific meaning is:

[0285] Non-zero power CSI-RS resource ID (nzp-CSI-RS-ResourceId): CSI-RS resource configuration ID.

[0286] periodicityAndOffset: The periodicity and time slot offset value of periodic / semi-persistent CSI-RS. All CSI-RS resources in a CSI-RS resource set are configured with the same periodicity, but the time slot offsets of different CSI-RS resources can be the same or different.

[0287] resourceMapping: defines the number of ports, CDM type, OFDM symbol, and subcarrier spacing of the CSI-RS resource in a time slot.

[0288] Specifically include:

[0289] H11, frequencyDomainAllocation: defines the frequency domain resource allocation within a PRB.

[0290] H12, firstOFDMSymbolInTimeDomain: defines the time domain resource allocation within a PRB.

[0291] H13, nrofPorts defines the number of CSI-RS ports.

[0292] H14, density defines the CSI-RS frequency domain density of each CSI-RS port and each PRB, and whether the CSI-RS is in an odd or even position when the CSI-RS frequency domain density value is 1 / 2.

[0293] H15, cdm-Type defines the CDM value and its mode.

[0294] H16, freqBand defines the number of PRBs spanned by the starting point and CSI-RS resources.

[0295] powerControlOffset: gives the ratio of PDSCH-EPRE to NZP CSI-RS-EPRE. When the UE obtains CSI feedback, the value range is [-8,15]dB with a step size of 1db.

[0296] powerControlOffsetSS: gives the ratio of NZP CSI-RS EPRE to SS / PBCH block EPRE.

[0297] scramblingID: defines a 10-bit CSI-RS scrambling ID.

[0298] BWP-Id: defines the BWP where the CSI-RS is located.

[0299] repetition: Associated with the CSI-RS resource set, this field can be set to ON / OFF. When set to ON, the terminal can assume that the CSI-RS resources in the NZP CSI-RS resource set are transmitted using the same downlink spatial transmission filter. This information field can only be configured when the measurement quantity reportQuantity reported by the high-level parameter associated with all report settings linked to the CSI-RS resource set is set to "cri-RSRP", "cri-SINR" or "none".

[0300] qcl-InfoPeriodicCSI-RS: indicates the QCL relationship with the CSI-RS resource, including the QCL source signal and the corresponding QCL type.

[0301] trs-Info: indicates that the antenna ports of all NZP-CSI-RS in the CSI-RS resource set are the same, and is used for UE specific configuration of TRS.

[0302] For a CSI-RS resource set, all CSI-RS resources except the NZP CSI-RS used for interference measurement have the same number of ports (nrofPorts) and frequency domain density (density), and have the same RB starting position, RB number, and CDM type.

[0303] If the UE's NZP CSI-RS resource set is configured with the trs-Info parameter, the UE assumes that the antenna ports with the same port index of the NZP CSI-RS resources configured in the NZP CSI-RS resource set are the same. For FR1, the UE can be configured with one or more NZP CSI-RS sets, one of which consists of four periodic NZP CSI-RS resources, occupying two consecutive time slots, each of which contains two periodic NZP CSI-RS resources. For FR2, the UE can also be configured with one or more NZP CSI-RS sets, one of which consists of two periodic CSI-RS resources in one time slot, or four periodic NZP CSI-RS resources in two consecutive time slots. If trs-Info is configured for the periodic NZP CSI-RS resource set, the UE does not need to configure the CSI reporting configuration CSIReportConfig. The UE does not need to support the simultaneous configuration of trs-Info and repetition in the NZP CSI RS ResourceSet.

[0304] III. Reference Signal Design for Idle UE

[0305] 3GPP Rel-17 studies the configuration of CSI-RS for UE in RRC-Idle / inactive mode from the perspective of energy saving, at least for channel tracking / AGC and other operations. For UE in RRC_IDLE / RRC_Inactive mode, the base station does not know which cell the UE resides in, and there is no RRC dedicated signaling similar to the connected state. Therefore, the current NR terminal energy saving project, for idle UE, only uses system messages to configure CSI-RS in principle, and there is no specific configuration plan.

[0306] For idle mode UEs, the latest progress of 3GPP introduces the Paging Advance Indication (PEI) signal to the paging message. PEI is sent before paging. If the terminal detects PEI, it wakes up the receiver to receive the paging message. Therefore, the base station also needs to configure PEI for idle mode terminals. The method of configuring PEI and CSI-RS is similar and there is a certain correlation.

[0307] Table 1 shows the CSI-RS resource information configured for the connected UE and the specific bit indication required, specifically:

[0308] Table 1 CSI-RS resource information configured by connected UE and the corresponding relationship between the specific bit indications required

[0309]

[0310]

[0311] If the CSI-RS / TRS is configured by the connected UE, the number of bits required is:

[0312] 1. All existing CSI-RS / TRS related parameters, including the related parameters in others, for CSI-RS / TRS occupying 1 symbol, each beam requires about 10 bytes, specifically: 2+10+4+9+9+12+4+8×2+7+4+1+2=80 bits.

[0313] 50+8×2+7+4+1+2=80 bits=10 bytes. For a TRS with 64 beams and 4 symbols, about 10×4×64=2560 bytes are required, which is much larger than the maximum bearer message of 372 bytes of the SIB message.

[0314] 2. All existing CSI-RS / TRS related parameters, excluding the related parameters in others, and binding SSB only requires 1 QCL information. For CSI-RS / TRS occupying 1 symbol, each beam requires about 7 bytes, specifically: 2+10+4+9+9+12+4+8=56bits=7bytes. For TRS with 64 beams and 4 symbols, it requires about 7×4×64=1790 bytes, which is much larger than the maximum bearer message of SIB message 372bytes.

[0315] The embodiments of the present application provide a resource configuration method, apparatus, network equipment and terminal equipment to solve the problem that the prior art fails to achieve energy saving and reduce system overhead when parameter information of reference signals is configured for idle / inactive mode terminals.

[0316] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0317] like Figure 4 As shown, an embodiment of the present invention provides a resource configuration method, which is executed by a network device and includes:

[0318] Step S401, sending configuration indication information and / or resource configuration information of a target reference signal to a terminal device in an idle state or an inactive state through a system information block SIB message;

[0319] The configuration indication information is used to indicate a generation method of resource configuration information of a target reference signal;

[0320] The resource configuration information includes at least one of the following:

[0321] A11, a first parameter set applied to a single target reference signal resource;

[0322] It can be understood that this first parameter set is a first parameter set exclusive to the target reference signal resource.

[0323] A12, a second parameter set applied to each target reference signal resource in a target reference signal resource set;

[0324] It can be understood that this second parameter set is a second parameter set exclusive to the target reference signal resource set.

[0325] A13, a third parameter set applied to each target reference signal resource in each target reference signal resource set in a target reference signal resource set group;

[0326] It can be understood that this third parameter set is a third parameter set exclusive to the target reference signal resource set group.

[0327] Here, it should be noted that the hierarchical relationship of the above A11 - A13 is: A11 < A12 < A13. A11 is the parameter set at the lowest level. From the hierarchical relationship, A11 can belong to A12 and / or A13.

[0328] Optionally, the target reference signal mentioned in the embodiments of this application includes: channel state information reference (CSI - RS). That is to say, at this time, A11 is the first parameter set applied to each CSI - RS resource, A12 is the second parameter set applied to each CSI - RS resource in the CSI - RS resource set, and A13 is the third parameter set applied to each CSI - RS resource in each CSI - RS resource set in the CSI - RS resource set group.

[0329] Optionally, the CSI - RS is a channel tracking reference signal (TRS). That is, in this case, the resource configuration information of the TRS sent by the network device. That is to say, when the terminal device receives such a CSI - RS, it will use this CSI - RS for channel tracking.

[0330] Here, it should be noted that the resource configuration information includes one of the following:

[0331] B11, the configuration information generated by the first method;

[0332] It should be noted that the first method is a configuration information generation method dedicated to idle state or non - active state target reference signals.

[0333] B12, the configuration information generated by the second method;

[0334] It should be noted that the second method is a method for generating configuration information of a connection-state target reference signal.

[0335] It should be noted here that the configuration indication information is used to indicate whether the resource configuration information is generated in the first manner or in the second manner.

[0336] It should be noted that the configuration indication information occupies 0 to N bits. Taking 1 bit as an example, a value of "0" indicates that the resource configuration information of the target reference signal is the configuration information generated by the second method, and a value of "1" indicates that the resource configuration information of the target reference signal is the configuration information generated by the first method. Specifically, the configuration information generation method of the idle state is defined by the protocol. Taking 2 bits as an example, different values ​​indicate different configuration methods, for example, "00" indicates that the configuration method is the first method, and "01" indicates that the configuration method is the second method.

[0337] Optionally, when the network device only sends configuration indication information, for example, when the configuration indication information is used to indicate that the resource configuration information is generated in a first manner, the terminal device adopts the resource configuration information generated in the first manner, that is, B11 previously sent by the network device; for example, when the configuration indication information is used to indicate that the resource configuration information is generated in a second manner, the terminal device adopts the resource configuration information generated in the second manner by default, that is, B12 previously sent by the network device.

[0338] It should be noted that, when the network device sends configuration indication information only in SIB information, since the configuration indication information occupies fewer bits, the system information overhead can be significantly reduced.

[0339] Optionally, when the terminal device only sends resource configuration information, the resource configuration information may be B11 or B12, for example, the network device may use B11 or B12 by default.

[0340] That is, when the configuration indication information is missing, it can be assumed that the configuration information is generated in the first manner or in the second manner.

[0341] Optionally, when the terminal device sends configuration indication information and resource configuration information at the same time, the generation method of the resource configuration information indicated by the configuration indication information is consistent with the generation method actually adopted by the resource configuration information, that is, when the configuration indication information indicates that the resource configuration information adopts the first method, the resource configuration information is B11, when the configuration indication information indicates that the resource configuration information adopts the second method, the resource configuration information is B12.

[0342] It should also be noted here that, in the embodiment of the present application, preferably, when the first method is used to generate configuration information, the bits occupied by the resource configuration information will not exceed the maximum number of bits carried by the SIB message, that is, 2976 bits (372 bytes).

[0343] It should be further noted that, when the resource configuration information is the configuration information generated by the first method, the resource configuration information satisfies one of the following:

[0344] C11. The first parameter set, the second parameter set and the third parameter set exist at the same time;

[0345] That is to say, in this case, the network device needs to send these three parameter sets at the same time, and the parameter sets sent by the network device at all times are these three.

[0346] C12, the second parameter set and the third parameter set exist at the same time;

[0347] That is to say, in this case, the network device needs to send these two parameter sets at the same time, and the parameter sets sent by the network device at all times are these two types.

[0348] C13. Only the first parameter set exists and / or both the second parameter set and the third parameter set exist;

[0349] That is to say, in this case, the network device can choose to send only the first parameter set at one moment, that is, use the first parameter set to independently configure the sending resources of the target reference signal, and choose to send the second parameter set and the third parameter set at the same time at another moment, that is, use the second parameter set and the third parameter set to configure the sending resources of the target reference signal.

[0350] The three parameter sets are described below.

[0351] 1. The first parameter set includes at least one of the following parameters:

[0352] D11, target reference signal scrambling code identification;

[0353] For example, when the target reference signal is a CSI-RS, the target reference signal scrambling code identifier is a CSI-RS scrambling code identifier, for example, the CSI-RS scrambling code identifier is a CSI-RS scrambling code ID.

[0354] That is to say, in this case, a separate target reference signal scrambling code identifier is configured for each resource, and the values ​​of the target reference signal scrambling code identifiers of different resources are different.

[0355] D12, validity duration of the target reference signal based on layer 1 signaling indication;

[0356] That is to say, in this case, a separate Validity duration is configured for each resource, and the values ​​of Validity duration for different resources are different.

[0357] For example, when the target reference signal is a CSI-RS, the valid time of the target reference signal indicated based on the layer one signaling is the valid time of the CSI-RS indicated based on the layer one signaling.

[0358] Specifically, the validity period of the target reference signal indicated based on the layer 1 signaling satisfies at least one of the following:

[0359] D121, the number of bits occupied is less than or equal to 4;

[0360] D122, the maximum number is less than or equal to 16.

[0361] It should be noted that the Validity duration contains M candidate values, each of which is [x(1), x(2), x(3), x(4), ... X(M)] × T, where the T value can be a parameter pre-configured by the system or a value agreed upon by the protocol; it can be a parameter common to multiple users or a user-specific parameter. For example: T can be a multiple of the default DRX cycle, such as T = 10 × DRX cycle, preferably, M is less than or equal to 16 (i.e., M ≤ 16), not exceeding 4 bits, and preferably M = 4; T can also be a value pre-agreed upon by the network and the terminal side.

[0362] 2. The second parameter set includes at least one of the following parameters:

[0363] D21, target reference signal scrambling code identification;

[0364] That is to say, in this case, a separate target reference signal scrambling code identifier is configured for each resource set, and the values ​​of the target reference signal scrambling code identifiers of different resources in the same resource set are the same.

[0365] For example, when the target reference signal is a CSI-RS, the target reference signal scrambling code identifier is a CSI-RS scrambling code identifier.

[0366] D22, target reference signal period and offset value (periodicityAndOffset);

[0367] That is to say, in this case, a separate periodicityAndOffset is configured for each resource set, and the values ​​of periodicityAndOffset of different resources in the same resource set are the same.

[0368] For example, when the target reference signal is a CSI-RS, the target reference signal period and offset value are the CSI period and offset value.

[0369] D23, quasi-co-site (QCL) reference (QCL reference);

[0370] That is to say, in this case, a separate QCL reference is configured for each resource set, and the QCL reference values ​​of different resources in the same resource set are the same.

[0371] D24, the number of time slots where the target reference signal is located (Slot number);

[0372] That is to say, in this case, a separate slot number is configured for each resource set, and the slot numbers of different resources in the same resource set have the same value.

[0373] For example, when the target reference signal is a CSI-RS, the number of time slots where the target reference signal is located is the number of time slots where the CSI-RS is located.

[0374] It should be noted that the number of time slots where the target reference signal is located satisfies at least one of the following:

[0375] D241, occupies 0 to 2 bits;

[0376] D242. Indicated either explicitly or implicitly.

[0377] It should be noted that, preferably, the value of the number of time slots is 0 to 1 bit.

[0378] D25, target reference signal resource set identifier;

[0379] For example, the target reference signal resource set identifier is a target reference signal resource set ID.

[0380] That is to say, in this case, a separate target reference signal resource set identifier is configured for each resource set, and the values ​​of the target reference signal resource set identifiers of different resource sets are different, while the values ​​of the target reference signal resource set identifiers of different resources under the same resource set are the same.

[0381] D26, validity period of target reference signal based on layer 1 signaling indication;

[0382] That is to say, in this case, a separate Validity duration is configured for each resource set, and the Validity duration values ​​of different resources in the same resource set are the same.

[0383] For example, when the target reference signal is a CSI-RS, the valid time of the target reference signal indicated based on the layer one signaling is the valid time of the CSI-RS indicated based on the layer one signaling.

[0384] 3. The third parameter set includes at least one of the following parameters:

[0385] D31, target reference signal period and offset value;

[0386] That is to say, in this case, a separate target reference signal period and offset value are configured for each resource set group, and the target reference signal period and offset value of different resources in the same resource set group are the same.

[0387] For example, when the target reference signal is a CSI-RS, the target reference signal period and offset value are the CSI-RS period and offset value.

[0388] D32, the value of the frequency domain starting resource block RB (startingRB);

[0389] That is to say, in this case, a separate startingRB is configured for each resource set group, and the startingRB values ​​of different resources in the same resource set group are the same.

[0390] D33, the number of RBs occupied in the frequency domain (nrofRBs);

[0391] That is to say, in this case, a separate nrofRBs is configured for each resource set group, and the values ​​of nrofRBs of different resources under the same resource set group are the same.

[0392] D34, validity period of target reference signal based on layer 1 signaling indication;

[0393] That is to say, in this case, a separate Validity duration is configured for each resource set group, and the Validity duration values ​​of different resources in the same resource set group are the same.

[0394] For example, when the target reference signal is a CSI-RS, the valid time of the target reference signal indicated based on the layer one signaling is the valid time of the CSI-RS indicated based on the layer one signaling.

[0395] D35, the ratio of the power of each resource unit of the non-zero power target reference signal to the power of each resource unit of the synchronization signal / physical broadcast channel block (SS / PBCH block) (powerControlOffsetSS);

[0396] That is to say, in this case, a separate powerControlOffsetSS is configured for each resource set group, and the powerControlOffsetSS values ​​of different resources in the same resource set group are the same.

[0397] For example, when the target reference signal is CSI-RS, the ratio of the power of each resource unit of the non-zero power target reference signal to the power of each resource unit of the SS / PBCH block is the ratio of the power of each resource unit of the non-zero power CSI-RS to the power of each resource unit of the SS / PBCH block.

[0398] D36, target reference signal resource set group identifier;

[0399] For example, the target reference signal resource set group identifier may be a target reference signal resource set group identifier.

[0400] That is to say, in this case, a separate target reference signal resource set group identifier is configured for each resource set group, and the values ​​of the target reference signal resource set group identifiers of different resources in the same resource set group are the same.

[0401] For example, when the target reference signal is a CSI-RS, the target reference signal resource set group identifier is a CSI-RS resource set group identifier.

[0402] D37, the number of time slots where the target reference signal is located (Slot number);

[0403] That is to say, in this case, a separate Slot number is configured for each resource set group, and the Slot numbers of different resources in the same resource set group have the same value.

[0404] For example, when the target reference signal is a CSI-RS, the number of time slots where the target reference signal is located is the number of time slots where the CSI-RS is located.

[0405] It should be noted here that any of the above parameters, such as the target reference signal scrambling code ID, cannot appear in parameter sets of different levels at the same time. For example, the target reference signal scrambling code ID can appear in the first parameter set or the second parameter set, but cannot appear in the first parameter set and the second parameter set at the same time.

[0406] It should also be noted here that, optionally, the target reference signal resource set group satisfies at least one of the following:

[0407] The maximum number is less than or equal to 6;

[0408] The number of bits occupied is less than or equal to 3.

[0409] Optionally, the target reference signal resource set satisfies at least one of the following:

[0410] The maximum number is less than or equal to 128;

[0411] The number of bits occupied is less than or equal to 7.

[0412] Preferably, the number of target reference signal resource sets in the embodiment of the present application is 64.

[0413] Optionally, the target reference signal resource satisfies at least one of the following:

[0414] The maximum number is less than or equal to 89;

[0415] The number of bits occupied is less than or equal to 7.

[0416] It should be noted that the above-mentioned constraints on the target reference signal resource set group, target reference signal resource set, target reference signal resource, Validity duration and Slot number can ensure that the generated resource configuration information does not exceed the maximum bit carried by a SIB, and can avoid the problem of increased terminal power consumption and increased base station side overhead caused by the terminal decoding multiple SIBs. Appropriately selecting the maximum value for each item will further reduce the signaling overhead.

[0417] Optionally, in the embodiment of the present application, the method may further include:

[0418] Receiving indication information is sent to a terminal device, where the receiving indication information is used to indicate whether the terminal device receives a target reference signal.

[0419] Optionally, the terminal device can determine whether to receive the target reference signal based on the received indication information. When the received indication information indicates that the target reference signal needs to be received, the terminal device receives the target reference signal based on the resource configuration information of the target reference signal. When the target reference signal is CSI-RS, the terminal device receives the CSI-RS for channel tracking and / or channel measurement.

[0420] That is to say, if the terminal device is indicated to have CSI-RS, the corresponding CSI-RS detection is performed according to the resource configuration information of the CSI-RS configured by the SIB message; otherwise, the terminal device does not need to perform the corresponding CSI-RS detection.

[0421] Optionally, the sending receiving indication information to the terminal device includes:

[0422] Determining layer 1 signaling for sending reception indication information;

[0423] The reception indication information is sent to the terminal device through the layer 1 signaling.

[0424] It should be noted that the layer 1 signaling mentioned in the embodiment of the present application includes at least one of a paging advance indication (PEI) and a paging downlink control information (DCI).

[0425] Optionally, the implementation manner of determining the layer 1 signaling used to send and receive indication information mainly includes:

[0426] Determining, through the first information, layer 1 signaling for sending and receiving indication information;

[0427] The first information includes at least one of the following: terminal capability information and second information.

[0428] Optionally, the terminal capability information may be pre-stored by the network device, or may be terminal capability information sent by the core network device and received by the network device. The terminal capability information is whether the terminal device supports the ability to detect the reception indication information carried by at least one of PEI and paging DCI.

[0429] Optionally, the second information includes but is not limited to the following:

[0430] The sending mode indication information is used to indicate that the receiving indication information is sent to the terminal device through at least one of the paging advance indication PEI and the paging downlink control information DCI.

[0431] It should be noted here that the terminal capability information can be the reception indication information of the target reference signal carried explicitly, or it can be the version information of the terminal. For example, Rel-16 UE does not support the reception indication information of CSI-RS carried by Paging DCI by default, and UEs after Rel-17 support PEI and / or support the reception indication information of CSI-RS carried by Paging DCI.

[0432] It should also be noted here that when the network device (such as a base station) indicates that the terminal device can support the reception indication information of CSI-RS based on PEI and the reception indication information of CSI-RS based on Paging DCI according to the first information and / or terminal capability information sent by the core network device, the network device decides to send the reception indication information of CSI-RS to the UE through PEI and / or Paging DCI. For example: when the UE is configured with the listening period of Paging, the UE needs to monitor. The base station side indicates CSI-RS through Paging DCI, which can reduce the overhead of PEI, improve the reception performance of PEI, and increase the energy saving gain of the terminal. Alternatively, in order to ensure the reception performance of CSI-RS for UE, the base station can send the reception indication information of CSI-RS on PEI and Paging DCI at the same time. Alternatively, when the base station sends PEI to the UE, it can also send the reception indication information of CSI-RS at the same time to avoid unnecessary CSI-RS reception by the UE.

[0433] Taking the communication between a base station and a terminal, and the target reference signal being a TRS as an example, the embodiments of the present application are specifically described in practical application as follows.

[0434] It should be noted here that the following application scenario takes TRS as an example, and the following application is also applicable to the case where the target reference signal is other reference signals other than TRS. For the case of other reference signals, no examples are given one by one in the embodiments of the present application.

[0435] Specific application situation 1.

[0436] The base station configures at least one TRS resource set group for the idle / inactive mode terminal and indicates the at least one TRS resource set group through layer 1 signaling.

[0437] Each TRS resource set group consists of one or more first parameter sets specific to TRS resources, one or more second parameter sets specific to TRS resource sets, and one or more third parameter sets specific to TRS resource set groups.

[0438] Note: The so-called "X exclusive" means that this parameter is common to the CSI-RS resource configuration within "X".

[0439] Optionally, when the number of SIBs of resource configuration information of the TRS configured by the base station does not exceed 2, it includes:

[0440] like Figure 6 As shown, the first parameter set dedicated to the TRS resource at least includes: CSI-RS scrambling code ID, CSI-RS scrambling code ID. And / or,

[0441] like Figure 5 As shown, the second parameter set exclusive to the TRS resource set includes at least: CSI-RS scrambling code ID, CSI-RS resource set ID, CSI-RS period and offset value (periodicityAndOffset), the ratio of NZP CSI-RS EPRE to SS / PBCH blockEPRE (powerControlOffsetSS), QCL reference, and Validity time.

[0442] The third configuration parameter set exclusive to the TRS resource set group includes at least one of the following: Slot number, CSI-RS period and offset value (periodicityAndOffset), frequency domain starting RB value (startingRB), number of RBs occupied in the frequency domain (nrofRBs), validity period of CSI-RS / TRS based on L1 signaling indication (Validity duration), ratio of NZP CSI-RSEPRE to SS / PBCH block EPRE (powerControlOffsetSS), and CSI-RS resource set group ID.

[0443] Optionally, when the number of SIBs of resource configuration information of the TRS configured by the base station does not exceed 1, the number of TRS resource sets is not greater than a preset value of 16, including:

[0444] An example of slot number configuration is as follows: For the time domain information of the TRS resource set, for example, when the configuration is the same as that of the connected TRS, the time domain symbol resource position occupied by the time domain is specified as follows: TRS in FR1 occupies two consecutive slots with a total of 4 symbols. The symbol position in each slot is as follows. TRS in FR2 can occupy one slot with a total of 2 symbols, or it can occupy two consecutive slots with a total of 4 symbols. The specific symbol position of each slot is as follows:

[0445] For FR1 and FR2: l∈{4,8}, l∈{5,9} or l∈{6,10},

[0446] For FR2: l∈{0,4}, l∈{1,5}, l∈{2,6}, l∈{3,7}, l∈{7,11}, l∈{8,12} or l∈{9,13}.

[0447] For two consecutive slots, the TRS symbol position corresponding to each slot is the same.

[0448] Therefore, the time domain information of the TRS resource set can be configured with a TRS resource-specific parameter, i.e., the time domain position of the first symbol firstOFDMSymbolInTimeDomain, and / or a second parameter specific to the TRS resource set, i.e., the number of slots (Slot number), to obtain 2 or 4 CSI-RS time domain resources. "Slot number" can be indicated by 0 to 2 bits according to explicit indication or implicit indication, specifically:

[0449] Explicit indication: 0 to 2 bits. For example: 1 bit: "0" indicates 1 slot, "1" indicates 2 slots. Or, 2 bits: decimal "1" indicates 1 slot, "2" indicates 2 slots. Or, bitmap 2 slots, "10" indicates 1 slot, "01" indicates 2 slots.

[0450] For example, if the UE is configured with the FR2 frequency band, the number of symbols occupied by the TRS can be specifically indicated by 1 bit as: 1 slot or 2 slots.

[0451] Implicit indication: If the UE is configured with the FR1 frequency band, the TRS is configured as 2 slots without explicit configuration.

[0452] The method for indicating the number of slots and the first symbol position is also applicable to the method for indicating reference signals of fixed symbol pattern or time slot pattern.

[0453] Taking the case where the number of SIBs for configuring TRS resource information of the base station does not exceed 1 as an example, a specific example of the configuration method of CSI-RS / TRS is as follows:

[0454] like Figure 5 As shown, in this case:

[0455] 1. When the base station can configure at most 1 TRS Resource set group, that is, the base station only needs L1 signaling to indicate whether the terminal receives TRS through 1 bit, the TRS-Resource set group ID does not need to be indicated, that is, 0 bits. Each TRS-Resource set group supports 64 TRS-Resource sets and can indicate up to 64 beams, which are indicated through 6 bits, and the slot number is a display indication, that is, 1 bit indication. The SIB message needs to carry 9+9+1+(6+2+12+10+4+4+6+2)×64×1=2963bit<2976bit.

[0456] 2. When the base station can configure up to 6 TRS Resource set groups, that is, the base station needs L1 signaling to indicate up to 6 TRS Resource set groups, the TRS Resource set group ID needs 3 bits to indicate. In this way, each TRS Resource set group supports up to 11 TRS Resource sets, indicated by 4 bits, and some TRS Resource sets can also be configured. The slot number is a display indication, that is, a 1-bit indication. The SIB message needs to carry 3+9+9+1+(4+2+12+10+4+4+6+2)×11×6=2926bit<2976bit.

[0457] Optionally, the following configurations may also be included:

[0458] The TRS resource ID information field in the third parameter set is optional and occupies 0 to 2 bits. For example, when the number of slots in FR1 or FR2 clearly indicates the number of resources, the TRS resource ID information field can be defaulted or specifically configured.

[0459] like Figure 6 As shown, the resource configuration information of TRS in this case is specifically:

[0460] 1. When the base station can be configured with at most one TRS-Resource set group, that is, the base station only needs to indicate whether the terminal receives TRS through 1 bit of L1 signaling, the TRS Resource set group ID does not need to be indicated, that is, 0 bit.

[0461] 2. When the CSI ResourceId information field is defaulted, each TRS Resource set group supports up to 39 TRS Resource sets and can indicate up to 39 beams, which is indicated by 6 bits. The slot number is a display indication, that is, a 1-bit indication. In this case, the SIB message needs to carry 9+9+1+2+(6+2+12+4+4+6+10×4)×39×1=2907bit<2976bits.

[0462] 3. When the TRS resource ID information field is 2 bits, each TRS resource set group supports up to 39 TRS resource sets and can indicate up to 36 beams, indicated by 6 bits. In this case, the SIB message needs to carry 9+9+1+2+(6+2+12+4+4+6+12×4)×36×1=2973bits<2976bits.

[0463] 4. When the base station can be configured with a maximum of 6 TRS Resource set groups, that is, the base station needs L1 signaling to indicate a maximum of 6 TRS Resource set groups, the TRS Resource set group ID needs 3 bits to indicate.

[0464] 5. When the TRS resource ID information field is defaulted, each TRS Resource set group supports up to 6 TRS Resource sets, indicated by 3 bits. Some TRS Resource sets can also be configured, and the slot number is a display indication, that is, a 1-bit indication. The SIB message needs to carry 3+9+9+1+2+(3+2+12+4+4+6+10×4)×6×6=2580bit<2976bits.

[0465] 6. When the TRS resource ID information field is 2 bits, each TRS resource set group supports up to 6 TRS resource sets, indicated by 3 bits. Some TRS resource sets can also be configured, and the slot number is a display indication, that is, a 1-bit indication. The SIB message needs to carry 3+9+9+1+2+(3+2+12+4+4+6+12×4)×6×6=2976bits=2976bits.

[0466] It should be noted that the beneficial effect of this application is that when TRS is configured for an idle / inactive mode terminal and when no more than two SIB information carry resource configuration information of the TRS, information indication of the TRS can be accurately performed.

[0467] Specific application situation 2.

[0468] The base station configures at least one TRS resource set group for the idle / inactive mode terminal and indicates the at least one TRS resource set group through layer 1 signaling.

[0469] Each TRS resource set group consists of one or more second parameter sets specific to TRS resource sets.

[0470] Specifically, the second parameter set exclusive to the TRS resource set includes at least one of the following: CSI-RS scrambling code ID, Slot number, CSI-RS resource set ID, CSI-RS periodicity and offset value (periodicityAndOffset), QCL reference;

[0471] The third parameter set exclusive to the TRS resource set group includes at least one of the following: startingRB, nrofRBs, Validity time, Slot number, CSI-RS resource set group ID, CSI-RS periodicity and offset value (periodicityAndOffset).

[0472] like Figure 7 As shown, the resource configuration information of a TRS in this case is specifically:

[0473] 1. When the base station can configure at most 1 TRS Resource set group, that is, the base station only needs L1 signaling to indicate whether the terminal receives TRS through 1 bit, the TRS Resource set group ID does not need to be indicated, that is, 0 bits. Each TRS Resource set group supports 89 TRS Resource sets and can indicate up to 89 beams, which is indicated by 7 bits, and the slot number is a display indication, that is, 1 bit indication. Here, the period and effective time of all TRS are the same. The SIB message needs to carry 9+9+1+12+2+(7+2+10+4+4+6)×89×1=2970bits<2976bits.

[0474] 2. When the base station can configure up to 6 TRS Resource set groups, that is, the base station needs L1 signaling to indicate up to 6 TRS Resource set groups, the TRS Resource set group ID needs 3 bits to indicate. In this way, each TRS Resource set group supports up to 16 TRS Resource sets, indicated by 4 bits, and some TRS Resource sets can also be configured. The slot number is a display indication, that is, a 1-bit indication. Here, the period and effective time of all TRS are the same. The SIB message needs to carry 3+9+9+1+12+2+(4+2+10+4+4+6)×16×6=2916bits<2976bits.

[0475] like Figure 8 As shown, the resource configuration information of another TRS in this case is specifically:

[0476] 1. When the base station can configure at most 1 TRS Resource set group, that is, the base station only needs L1 signaling to indicate whether the terminal receives TRS through 1 bit, the TRS Resource set group ID does not need to be indicated, that is, 0 bits. Each TRS Resource set group supports up to 65 TRS Resource sets and can indicate up to 65 beams, which are indicated through 7 bits, and the slot number is displayed, that is, 1 bit. The SIB message needs to carry 9+9+1+2+(7+2+12+10+4+4+6)×65×1=2946bit<2976bit.

[0477] When the second resource set only has CSI-RS scrambling code ID and QCL reference, the number of slots is 0 bits, each TRS Resource set group supports up to 128 TRS Resource sets, and can indicate up to 128 beams, which is indicated by 7 bits. The SIB message needs to carry 9+9+2+(7+10+6)×128×1=2964bits<2976bits.

[0478] 2. When the base station can configure up to 6 TRS Resource set groups, that is, the base station needs L1 signaling to indicate up to 6 TRS Resource set groups, the TRS Resource set group ID needs 3 bits to indicate. In this way, each TRS Resource set group supports up to 11 TRS Resource sets, indicated by 4 bits, and some TRS Resource sets can also be configured. The slot number is a display indication, that is, a 1-bit indication. The SIB message needs to carry 3+9+9+1+2+(4+2+12+10+4+4+6)×11×6=2796bit<2976bit.

[0479] It should be noted that the beneficial effect of this application scenario is that the configuration of TRS for idle / inactive mode terminals can be controlled in one SIB information, avoiding the generation method of resource configuration information applied to the connected TRS exceeding the limit of the amount of data carried by the SIB information, and accurately indicating information to the TRS.

[0480] Specific application situation 3.

[0481] The base station configures at least one TRS resource set group for the idle / inactive mode terminal and indicates the at least one TRS resource set group through layer 1 signaling.

[0482] The base station independently configures each TRS resource set group through the first parameter set dedicated to the TRS resource, that is, each TRS resource set group contains only one or more first parameter sets dedicated to the TRS resource, or

[0483] The sending resources corresponding to the TRS resource set group are configured by simultaneously configuring at least one or more TRS resource set-specific second parameter sets and one or more TRS resource set group-specific third parameter sets.

[0484] Note: The two methods described here mean that the base station side can configure either one of them, but the two cannot be used at the same time.

[0485] For the first parameter set exclusive to TRS resource, each TRS resource set group is independently configured. The first parameter set at least includes: CSI-RS scrambling code ID, CSI-RS resource ID, QCL reference, CSI-RS period and offset value (periodicityAndOffset), startingRB, nrofRBs, Validity time, Slot number, powerControlOffsetSS.

[0486] It should be noted that the CSI-RS ResourceId information field in the third parameter set is optional. For example, 0 to 2 bits, when the number of slots in FR1 or FR2 clearly indicates the number of resources, the CSI-ResourceId information field can be default or specifically configured.

[0487] Configuring the TRS resource set group in a manner that includes at least a second parameter set exclusive to the TRS resource set and a third parameter set exclusive to the TRS resource set group includes:

[0488] The second parameter set exclusive to the TRS resource set includes at least: a CSI-RS scrambling code ID and a CSI-RS resource set ID;

[0489] The configuration of the TRS resource set group in a third parameter set exclusive to the TRS resource set group includes at least: the validity duration of TRS indicated by L1 signaling, Slot number, CSI-RS period and offset value, frequency domain starting RB value (startingRB), the number of RBs occupied in the frequency domain (nrofRBs), and the ratio of NZP CSI-RS EPRE to SS / PBCH blockEPRE (powerControlOffsetSS).

[0490] For the first parameter set dedicated to TRS resource, each CSI-RS / TRS resource set group is independently configured, such as Fig. 9 As shown, the resource configuration information of a TRS in this case is specifically:

[0491] 1. When the base station can configure at most one TRS-Resource set group, that is, the base station only needs L1 signaling to indicate whether the terminal receives CSI-RS / TRS through 1 bit, the TRS-Resource set group ID does not need to be indicated, that is, 0 bit.

[0492] 2. When the CSI-ResourceId information field needs to be indicated by 0 to Z1 bits, and the indication value is 0 to Z, the slot number is a display indication, that is, a 1-bit indication. A TRS-Resource set group supports up to 45 CSI-RS resources, which requires 6 bits. The amount of information that the SIB message needs to carry is (9+9+1+2+2+12+4+4+6+10+6)×45×1=2925bits<2976bits.

[0493] 3. When the base station can configure up to 6 TRS-Resource set groups, that is, the base station needs L1 signaling to indicate up to 6 TRS-Resource set groups, the TRS-Resource set group ID needs 3 bits to indicate. 1 TRS-Resource set group supports up to 7 CSI-RS resources, which requires 3 bits. The amount of information that the SIB message needs to carry is 3+(9+9+1+2+2+12+4+4+6+10+3)×7×6=2607bits<2976bits.

[0494] Note: When not limited to the number of SIBs, specific configuration can be performed with the first parameter set, that is, parameter configuration is performed according to the CSI-RS in the first parameter set, and the transmission of more than 1 SIB can be performed.

[0495] For configuring the TRS resource set group in a manner that includes at least a second parameter set exclusive to the TRS resource set and a third parameter set exclusive to the TRS resource set group, one implementation is the same as the specific application scenario 2, and another implementation is as follows Fig.10 The resource configuration information of the TRS shown is specifically:

[0496] 1. When the base station can configure at most 1 TRS-Resource set group, that is, the base station only needs L1 signaling to indicate whether the terminal receives CSI-RS / TRS through 1 bit, the TRS-Resource set group ID does not need to be indicated, that is, 0 bits. Each TRS-Resource set group supports up to 89 TRS-Resource sets, indicated by 7 bits. There is only one CSI-RS / TRS Resource in each TRS-Resource set, and the slot number is a display indication, that is, 1 bit indication. The SIB message needs to carry 9+9+1+2+12+(2+10+4+4+6+7)×89×1=2970bits<2976bits.

[0497] 2. When the base station can be configured with up to 6 TRS-Resource set groups, that is, the base station needs L1 signaling to indicate up to 6 TRS-Resource set groups, the TRS-Resource set group ID needs 3 bits to indicate. Each TRS-Resource set group supports up to 16 TRS-Resource sets, indicated by 4 bits, and there is only one CSI-RS / TRS Resource in each TRS-Resource set. The slot number is a display indication, that is, a 1-bit indication. The SIB message needs to carry 3+9+9+1+2+12+(2+10+4+4+6+4)×16×6=2916bits<2976bits.

[0498] It should be noted that the beneficial effect of this application is that the configuration of TRS for idle / inactive mode terminals can be controlled in 1 SIB information, avoiding the configuration of connected TRS exceeding the limit of the amount of data carried by the SIB information, and accurately indicating the information to TRS.

[0499] It should be noted that, in the discussion of the TRS configuration method in idle / inactive mode, it has been decided to adopt SIB signaling configuration, but there is no specific plan. For the RRC signaling configuration method of the connected CSI-RS, when it is directly used for SIB transmission, it cannot be ensured that it can exist before paging, resulting in a decrease in energy saving gain, and reusing the RRC signaling configuration method of the connected CSI-RS will make the SIB signaling overhead huge. The embodiment of the present invention provides the resource configuration information of CSI-RS / TRS and the binding of paging / SSB, which is beneficial to terminal energy saving and can greatly reduce the system message signaling overhead.

In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0503] Network devices and terminal devices can each use one or more antennas for multiple-input multiple-output (MIMO) transmission.

Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoded transmission or beamforming transmission, etc.
