Patent Application
20250007667
This application claims priority to the Chinese patent application No. 202111308795.9 filed in China on Nov. 5, 2021, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of communication technologies, in particular, relates to a resource configuration method, a resource configuration apparatus, a network device, and a terminal device.
Terminal energy-saving discussion in n Release 17 (Rel-17) agrees that a base station will configure Channel-State-Information Reference Signal (CSI-RS) resources for a terminal in a connected mode to a terminal in idle (Idle)/inactive (Inactive) state and for at least channel tracking functionality. Since end time of data transmission for user equipment (User Equipment, UE) in the connected mode is random, the CSI-RS resources notified by the base station to the terminal may frequently change. Once the CSI-RS resources change, the base station needs to reconfigure the resources through system messages. Frequently reading system messages by the terminal can lead to an increase in power consumption of the terminal. The energy-saving benefits brought by introducing the CSI-RS to the terminal in Idle/Inactive mode will be greatly reduced. In addition, an overhead of the system message is too high, which also increases the power consumption of reception of the terminal. More importantly, it brings a significant overhead to the base station side. Therefore, the parameter information of CSI-RS is configured for the terminal in Idle/inactive mode through System Information Block (SIB) messages.
If the parameter configuration of CSI-RS/tracking reference signal (Tracking Reference Signal, TRS) in the connected mode of the related art is fully reused, it will exceed the maximum carry information limit of SIB messages, which is 2976 bits (372 bytes). If the configured information exceeds the maximum carry information limit (the maximum number of carried information) of SIB messages, the SIB message will be further divided and transmitted through multiple physical downlink shared channels (Physical Downlink Shared Channel, PDSCH). SIB messages can be obtained by the terminal through receiving multiple PDSCHs, which increases the time required to obtain SIB messages. Once an error occurs in one of the SIB messages (with an error rate of 10%), more time is required, which can result in a higher latency and power consumption when the terminal receives the SIB messages.
Embodiments of the present disclosure provide a resource configuration method and apparatus, a network device, and a terminal device, to solve the problem of the related art that it is not able to achieve energy saving and reduce system overhead when configuring parameter information of reference signals for a terminal in Idle/inactive mode.

Embodiments of the present disclosure are described below with reference to the drawings. The resource configuration method, the resource configuration apparatus, the network device, and the terminal device provided by the embodiments of the present disclosure may be applied in a radio communication system. The radio communication system may be a system (hereinafter referred to as 5G system for short) adopting the fifth generation (5G) mobile communication technology, those skilled in the art can understand that the 5G NR system is only used as an example and not as a limitation.
Referring to
Firstly, some concepts related to the embodiments of the present disclosure will be explained as follows.
For New Radio (NR) systems, optimization of power saving and reception robustness in radio resource control IDLE (RRC_IDLE)/radio resource control Inactive (RRC_Inactive) mode is also important. For example, low complexity NR terminals, such as smart wearable devices or sensor devices mainly work in RRC_IDLE/RRC_Inactive mode, have stricter requirements for power saving than ordinary NR terminals. For user equipment (User equipment, UE) that work in RRC_IDLE/RRC_Inactive mode for a long time, UE will receive paging messages and system information (SI). Unlike Long Term Evolution (LTE) systems, NR terminals do not have a common reference signal (CRS) in RRC_IDLE/RRC_Inactive mode. Therefore, before receiving paging information at a corresponding paging occasion (PO), the terminal needs to first receive a synchronization signal block (SSB) to perform time/frequency tracking (T/F tracking) and Automatic Gain Control (AGC) operations to improve receiving performance of Paging messages (including Paging downlink control information (DCI) and Paging Physical Downlink Shared Channel (PDSCH)), as shown in
In addition to paging and SI, the forthcoming evolution of NR standards is considering an introduction of a multimedia broadcast multicast system similar to that in LTE. The multimedia broadcast multicast system sends periodically in RRC_idle mode and requires UE to first detect and schedule DCI. However, since the NR system in Stand Alone (SA) networking does not have the CRS of the LTE system, its channel tracking operation is similar to paging, which is also based on a SSB operation, so it has the same power consumption and reception accuracy issues as the paging operation. It should be further clarified that SI in NR includes a Master Information Block (MIB) and its System Information Blocks (SIBs). SIBs are divided into SIB1 and other system information (other SIB) (currently the NR protocol includes SIB2-SIB9), where SIB1 is also known as Remaining Minimum SI (RMSI).
In Active Time, the base station configures various reference signals RSs (Reference Signal) for UE for channel quality measurement and beam management with various purposes. The RSs can include CSI-RS for tracking (i.e. CSI-RS for tracking, i.e. Tracking RS (TRS)), where 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 RSs can also include CSI-RS (i.e. CSI-RS for mobility) for mobility measurement, where the terminal uses the CSI-RS for mobility configured by the base station to perform Radio Resource Management (RRM) measurement operations. The RSs may also include CSI-RSs for channel quality, measurement reporting, and beam management.
NR release 15 (i.e. Rel-15), release 16 (i.e. Rel-16) protocols only allow UE-exclusive CSI-RS resources to be configured for terminals in the RRC_connected mode through dedicated RRC signaling. The base station utilizes high-level signaling “CSI-ResourceConfig” and non-zero power CSI-RS resource set “NZP-CSI-RS-ResourceSet” to configure one or more NZP CSI-RS resource sets (up to 16 NZP CSI-RS resource sets in a CSI configuration) for terminals in the connected mode. Each resource set contains K≥1 NZP CSI-RS resources (up to 64, 128 NZP CSI-RS resources in a resource set).
The high-level parameters related to CSI-RS resources including CSI measurement configuration (CSI-MeasConfig), CSI resource configuration (CSI-ResourceConfig), NZP-CSI-RS ResourceSet and non-zero power CSI-RS resource (NZP-CSI-RS resource), and the structure of NZP CSI-RS resources configured for UE, are shown in
The specific meaning is:
The parameters specifically includes:
For a CSI-RS resource set, all CSI-RS resources except for NZP CSI-RSs used for interference measurement have the same quantity of ports (nrofPorts) and frequency-domain density, and have the same starting position of Resource blocks (RBs), quantity of RBs, and the same CDM type.
If the trs-Info parameter is configured in the NZP CSI-RS resource set of UE, UE assumes that the antenna ports with the same port index for NZP CSI-RS resources configured in the NZP CSI-RS resource set are the same. For FR1, UE can be configured with one or more NZP CSI-RS sets, where one NZP CSI-RS resource set consists of four periodic NZP CSI-RS resources occupying two consecutive slots. Each slot contains two periodic NZP CSI-RS resources. For FR2, UE can also be configured with one or more NZP CSI-RS sets, where one NZP CSI-RS resource set can be composed of two periodic CSI-RS resources in one slot, or four periodic NZP CSI-RS resources in two consecutive slots. If the trs-Info is configured in the periodic NZP CSI-RS resource set, then UE does not need to be configured with CSI reporting configuration CSI ReportConfig. UE does not need to support the simultaneous configuration of trs-Info and replication in NZP CSI RS ResourceSet.
3GPP Rel-17 studies, from an energy-saving perspective, the UE in the RRC_Idle/inactive mode is configured with CSI-RSs at least for channel tracking (channel tracking)/AGC and other operations. For the UE in the RRC_IDLE/RRC_Inactive mode, the base station is not sure which cell the UE resides in, and there is no dedicated RRC signaling similar to that in the connected mode. Therefore, currently in the NR terminal energy-saving project, for UE in the idle mode, CSI-RS configuration is only based on system messages in principle, without any specific configuration plan.
For the idle UE, the latest progress of 3GPP introduces a paging early indication (Paging Early Indication, PEI) signal for paging messages. The PEI is sent before the paging, and if the terminal detects the PEI, it wakes up a receiver to receive the paging message, so the base station also needs to configure the PEI for the terminal in the idle mode. The method of configuring the PEI is similar to that for the CSI-RS, and there is a certain correlation.
Table 1 shows the CSI-RS resource information configured for UE in the connected mode and specific required bit indications, specifically:
If CSI-RS/TRS is configured according to the UE in the connected mode, the required quantity of bits is:
1. in case of the parameters related to CSI-RS/TRS in all related art, including relevant parameters in others; for CSI-RS/TRS that occupies 1 symbol, each beam requires approximately 10 bytes, specifically, 2+10+4+9+9+12+4+8×2+7+4+1+2=80 bits.
50+8×2+7+4+1+2=80bits=10 bytes. For a TRS with 64 beams configured with 4 symbols, it requires approximately 10×4×64=2560 bytes, which is much larger than the maximum carrying message of SIB messages of 372 bytes.
2. In case of all parameters related to CSI-RS/TRS in the related art which do not include relevant parameters in others, binding a SSB only requires 1 QCL information. For CSI-RS/TRS that occupies 1 symbol, each beam requires about 7 bytes, specifically 2+10+4+9+9+12+4+8=56bits=7 bytes. For a TRS with 64 beams configured with 4 symbols, it requires about 7×4×64=1790 bytes, which is much larger than the maximum carrying message of SIB messages of 372 bytes.
The embodiments of the present disclosure provide a resource configuration method, a resource configuration apparatus, a network device, and a terminal device, to solve the problem of the related art not being able to achieve energy saving and reduce system overhead when not configuring parameter information of reference signals for a terminal in Idle/inactive mode.
The method and the apparatus are based on the same application concept. As the principle of solving problems by the method or the apparatus is similar, the implementation of the apparatus and the method can refer to each other, and the repetition between the method and the apparatus will not be repeated.
As shown in
Step S401, send configuration indication information and/or resource configuration information of a target reference signal to a terminal device in an idle mode or an inactive mode, by using system information block SIB messages.
The configuration indication information is configured to indicate a generation method of the resource configuration information of the target reference signal;
The resource configuration information includes at least one of the following:
It should be noted that the hierarchical relationship between A11-A13 mentioned above is: A11<A12<A13, where A11 is the smallest level of the parameter sets. From the hierarchical relationship, A11 can be attributed to A12 and/or A13.
Optionally, the target reference signal in the embodiments of the present disclosure includes: channel-state-information reference signals (CSI-RS), that is, 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 a CSI-RS resource set, and A13 is the third parameter set applied to each CSI-RS resource set in a CSI-RS resource set group.
Optionally, the CSI-RS is a channel tracking reference signal (TRS), which is the resource configuration information of the TRS sent by the network device in this case. That is to say, when the terminal device receives such CSI-RS, it will use the CSI-RS for channel tracking.
It should be noted that the resource configuration information includes one of the following:
It should be noted that the configuration indication information is configured to indicate whether the resource configuration information is generated by the first method or the second method.
It should be noted that the configuration indication information occupies 0˜N bits. Taking 1 bit as an example, the “0” value indicates that the resource configuration information of the target reference signal is generated using the second method, and the “1” value indicates that the resource configuration information of the target reference signal is generated by using the first method. Specifically, the generation method of configuration information in the idle mode is defined by a 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.
Optionally, when the network device only sends configuration indication information, for example, the configuration indication information is configured to indicate that in a case where the resource configuration information is generated by the first method, the terminal device uses the resource configuration information generated by the first method, which is the B11 previously sent by the network device. For example, the configuration indication information is configured to indicate that in a case where the resource configuration information is generated by the second method, the terminal device uses by default the resource configuration information generated by the second method, which is the B12 previously sent by the network device.
It should be noted that when the network device only sends the configuration indication information in SIB messages, the system information overhead can be significantly reduced due to the fact that the configuration indication information occupies fewer bits.
Optionally, in a case where the terminal device only sends the resource configuration information, the resource configuration information can be B11 or B12, for example, the network device can use B11 or B12 by default.
That is to say, when the configuration indication information is the default, it can use by default the first method to generate configuration information or use the second method to generate configuration information.
Optionally, in a case where the terminal device simultaneously sends configuration indication information and resource configuration information, the generation method of the resource configuration information indicated by the configuration indication information is consistent with the actual generation method of the resource configuration information. That is to say, when the configuration indication information indicates that the resource configuration information adopts the first method, the resource configuration information is B11, and when the configuration indication information indicates that the resource configuration information adopts the second method, the resource configuration information is B12.
It should also be noted that in the embodiments of the present disclosure, it is preferred that when the configuration information is generated by using the first method, the bits occupied by the resource configuration information will not exceed the maximum quantity of bits carried by the SIB messages, which is 2976 bits (372 bytes).
Furthermore, it should be noted that when the resource configuration information is generated by using the first method, the resource configuration information satisfies one of the following:
The following is an explanation of these three parameter sets.
For example, when the target reference signal is CSI-RS, the scrambling identification of the target reference signal is CSI-RS scrambling identification, for example, the CSI-RS scrambling identification is CSI-RS scrambling ID.
That is to say, in this case, a separate scrambling identification of the target reference signal is configured for each resource, and the values of the scrambling identification of the target reference signal for different resources are different.
That is to say, in this case, a separate validity duration is configured for each resource, and the values of the validity duration for different resources are different.
For example, in a case where the target reference signal is CSI-RS, the validity duration of the target reference signal based on layer-one signaling indication is the validity duration of CSI-RS based on layer-one signaling indication.
Specifically, the validity duration of the target reference signal based on layer-one signaling indication satisfies at least one of the following:
It should be noted that the validity duration contains M selected values, each of values is [x(1), x(2), x(3), x(4), . . . . X(M)]×T. The T value can be a pre-configured parameter in the system or a value agreed upon in the protocol; it can be a common parameter for multiple users, or it can be a user-specific parameter. For example, T can be a multiple of the default discontinuous reception (Discontinuous Reception, 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 more preferably, M=4; T can also be a pre-agreed value between the network and the terminal side.
That is to say, in this case, a separate scrambling identification of the target reference signal is configured for each resource set, and the values of the scrambling identification of the target reference signal for different resources in the same resource set are the same.
For example, when the target reference signal is CSI-RS, the scrambling identification of the target reference signal is CSI-RS scrambling identification.
That is to say, in this case, a separate periodicity AndOffset is configured for each resource set, and the values of the periodicity AndOffset for different resources in the same resource set are the same.
For example, when the target reference signal is CSI-RS, the periodicity and offset value of the target reference signal is CSI periodicity and an offset value.
That is to say, in this case, a separate QCL reference is configured for each resource set, and the values of the QCL reference for different resources in the same resource set are the same.
That is to say, in this case, a separate Slot number is configured for each resource set, and the values of the Slot number for different resources in the same resource set are the same.
For example, when the target reference signal is CSI-RS, the quantity of slots in which the target reference signal is located is equal to the quantity of slots in which CSI-RS is located.
It should be noted that the quantity of slots in which the target reference signal is located satisfies at least one of the following:
It should be noted that, preferably, the value of the quantity of slots is 0-1 bits.
For example, the identification of the target reference signal resource set is a target reference signal resource set ID.
That is to say, in this case, a separate target reference signal resource set ID is configured for each resource set. The values of the target reference signal resource set ID for different resource sets are different, and the values of the target reference signal resource set ID for different resources in the same resource set are the same.
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.
For example, when the target reference signal is CSI-RS, the validity duration of the target reference signal based on layer-one signaling indication is the validity duration of the CSI-RS based on layer-one signaling indication.
That is to say, in this case, a separate periodicity and an offset value of the target reference signal is configured for each resource set group, and the values of the periodicity and an offset value of the target reference signal for different resources in the same resource set group are the same.
For example, when the target reference signal is CSI-RS, the periodicity and an offset value of the target reference signal is CSI-RS periodicity and offset value.
That is to say, in this case, a separate startingRB is configured for each resource set group, and the startingRB values for different resources in the same resource set group are the same.
That is to say, in this case, separate nrofRBs are configured for each resource set group, and the values of nrofRBs for different resources in the same resource set group are the same.
That is to say, in this case, a separate validity duration is configured for each resource set group, and the validity duration values for different resources in the same resource set group are the same.
For example, when the target reference signal is CSI-RS, the validity duration of the target reference signal based on layer-one signaling indication is the validity duration of CSI-RS based on layer-one signaling indication.
That is to say, in this case, a separate powerControlOffsetSS is configured for each resource set group, and the values of powerControlOffsetSS for different resources in the same resource set group are the same.
For example, when the target reference signal is CSI-RS, the ratio of the power of each resource element in the non-zero power target reference signal to the power of each resource element in the SS/PBCH block is the ratio of the power of each resource element in the non-zero power CSI-RS to the power of each resource element in the SS/PBCH block.
For example, the identification of target reference signal resource set group can be the identification of target reference signal resource set group.
That is to say, in this case, a separate identification of target reference signal resource set group is configured for each resource set group, and the values of the identification of target reference signal resource set group for different resources in the same resource set group are the same.
For example, when the target reference signal is CSI-RS, the identification of target reference signal resource set group is identification of CSI-RS resource set group.
That is to say, in this case, a separate Slot number is configured for each resource set group, and the values of the Slot number for different resources in the same resource set group are the same.
For example, when the target reference signal is CSI-RS, the quantity of slots in which the target reference signal is located is equal to the quantity of slots in which CSI-RS is located.
It should be noted that for any of the above parameters, such as the target reference signal scrambling ID, it cannot appear in different levels of parameter sets at the same time. For example, the scrambling ID of the target reference signal can appear in the first parameter set or the second parameter set, but cannot appear in both the first parameter set and second parameter set at the same time.
It should also be noted that, optionally, the target reference signal resource set group satisfies at least one of the following:
Optionally, the target reference signal resource set satisfies at least one of the following:
Preferably, the quantity of target reference signal resource sets in the embodiments of the present disclosure is 64.
Optionally, the target reference signal resource satisfies at least one of the following:
It should be noted that the above constraints on the target reference signal resource set group, the target reference signal resource set, the target reference signal resource, the Validity duration, and the Slot number can ensure that the generated resource configuration information does not exceed the maximum number of bits carried by one SIB, which can avoid the problem that decoding multiple SIBs by a terminal leads to increased terminal power consumption and the base station side overhead, choosing the appropriate maximum value for each of the target reference signal resource set group, the target reference signal resource set, the target reference signal resource, the Validity duration, and the Slot number will further reduce signaling overhead.
Optionally, in the embodiments of the present disclosure, the method may further include:
Optionally, the terminal device can determine whether to receive the target reference signal based on the receiving indication information. When the receiving indication information indicates the need for receiving the target reference signal, the terminal device can receive the target reference signal based on the resource configuration information of the target reference signal. When the target reference signal is the CSI-RS, the terminal device receives the CSI-RS for channel tracking and/or channel measurement.
That is to say, if the terminal device is indicated with the CSI-RS, corresponding CSI-RS detection will be performed according to the resource configuration information of CSI-RS configured in the SIB messages. Otherwise, the terminal device does not need to undergo corresponding CSI-RS detection.
Optionally, sending the receiving indication information to the terminal device includes:
It should be noted that the layer-one signaling in the embodiments of the present disclosure includes at least one of paging early indication (PEI) and paging downlink control information (DCI).
Optionally, the implementation of determining the layer-one signaling used for sending the receiving indication information mainly includes:
The first information includes at least one of the following: terminal capability information and second information.
Optionally, the terminal capability information can be pre-saved by the network device, or can be terminal capability information sent by the core network device and received by the network device. The terminal capability information refers to whether the terminal device supports the ability to detect the receiving indication information carried by at least one of PEI and paging DCI.
Optionally, the second information includes but is not limited to one of the following:
It should be noted that the terminal capability information can be explicitly carried receiving indication information of the target reference signal, or it can be version information of the terminal. For example, Rel-16 UE does not support Paging DCI carrying the receiving indication information of the CSI-RS by default, while UE after Rel-17 supports PEI and/or Paging DCI carrying the receiving indication information of CSI-RS.
It should also be noted that when the network device (such as a base station) indicates, based on the first information and/or terminal capability information sent by the core network device, that the terminal device can support receiving indication information of the CSI-RS carried by PEI carrying and carried by the Paging DCI, the network device determines to send the receiving indication information of the CSI-RS to the UE through PEI and/or Paging DCI. For example, when the UE is configured with a monitoring cycle of Paging, the UE needs to monitor. The base station side can indicate CSI-RS through Paging DCI, which can reduce the cost of PEI, improve the receiving performance of PEI, and increase the energy-saving gain of the terminal. Optionally, in order to ensure the reception performance of UE to CSI-RS, the base station can simultaneously send the receiving indication information of the CSI-RS on both PEI and Paging DCI. Optionally, when the base station sends PEI to the UE, it can simultaneously send the receiving indication information of the CSI-RS to avoid unnecessary receiving the CSI-RS by the UE.
Taking the communication between the base station and the terminal and the target reference signal being TRS, as an example, the specific explanation of the embodiments of the present disclosure in practical applications is as follows.
It should be noted that the following application situations only take TRS as an example, and the following applications also apply to cases where the target reference signal is other reference signals besides TRS. For cases where other reference signals are used, examples will not be provided in the embodiments of the present disclosure.
The base station configures at least one TRS resource set group for a terminal in idle/inactive mode, and indicates the at least one TRS resource set group through layer-one signaling.
Each TRS resource set group consists of one or more first parameter sets exclusive to TRS resources, one or more second parameter sets exclusive to TRS resource sets, and one or more third parameter sets exclusive to TRS resource set groups.
Note: The meaning of “exclusive to X” is that the parameter is common to the CSI-RS resource configuration within “X”.
Optionally, when the quantity of SIBs configuring the resource configuration information of TRS by the base station does not exceed 2, following is included.
As shown in
As shown in
The third parameter set exclusive to a TRS resource set group includes at least one of the following: Slot number, CSI-RS periodicity and offset value (periodicity AndOffset), frequency-domain starting RB value (startingRB), quantity of RBs occupied by the frequency domain (nrofRBs), validity duration of CSI-RS/TRS based on L1 signaling indication, ratio of NZP CSI-RS EPRE to SS/PBCH block EPRE (powerControlOffsetSS), and a CSI-RS resource set group ID.
Optionally, when the quantity of SIBs configuring the resource configuration information of TRS by the base station does not exceed 1, the quantity of TRS resource sets does not exceed the preset value of 16, following is included.
Example of configuring the slot number: for the time domain information of the TRS resource set, for example, when configuration is the same as that of TRS in the connected mode, the position of time-domain symbol resources occupied in time domain is specified as occupying a total of four symbols in two consecutive slots by TRS in FR1. The symbol position in each slot is as follows. In FR2, TRS can occupy one slot, totaling two symbols, or two consecutive slots, totaling four symbols. The specific position of symbols in each slot is:
For two consecutive slots, each slot corresponds to the same TRS symbol position.
Therefore, the time-domain information of the TRS resource set can configure a parameter exclusive to a TRS resource, that is, a time domain position of the first symbol firstOFDMSymbolInTimeDomain, and/or a second parameter exclusive to a TRS resource set, that is, the Slot number, to obtain 2 or 4 CSI-RS time-domain resources. “Slot number” can be indicated explicitly or implicitly, through 0-2 bits, specifically:
Explicit indication: 0-2 bits. For example: 1 bit: “0” represents 1 slot, “1” represents 2 slots. Optionally, 2 bits: decimal “1” indicates 1 slot, and “2” indicates 2 slots. Optionally, bit mapping to 2 slots, “10” indicates 1 slot and “01” indicates 2 slots.
For example, if the UE is configured with the FR2 frequency band, the quantity of symbols occupied by TRS can be indicated by 1 bit, specifically as: 1 slot or 2 slots.
Implicit indication: If the UE is configured with the FR1 frequency band, the TRS configured with 2 slots does not need an explicit configuration.
The indication method for the quantity of Slots and the position of the first symbol is also applicable to the indication method for reference signals with a fixed symbol pattern or a slot pattern.
For example, if the quantity of SIBs configuring the resource configuration information of TRS by the base station does not exceed 1, the specific configuration method for CSI-RS/TRS is as follows:
As shown in
1. When the base station can configure up to 1 TRS Resource set group, that is, the base station only needs 1-bit L1 signaling to indicate whether the terminal receives the TRS, 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, which can indicate up to 64 beams through 6 bits, and the slot number is indicated in the explicit indication, which is 1 bit of indication. SIB messages need to carry 9+9+1+ (6+2+12+10+4+4+6+2)×64×1=2963 bits<2976 bits.
2. When the base station can configure up to 6 TRS Resource set groups, that is, the base station needs the L1 signaling to indicate a maximum of 6 TRS Resource set groups, then the TRS Resource set group ID needs to be indicated by 3 bits. In this way, each TRS Resource set group can support up to 11 TRS Resource sets, indicated through 4 bits. Part of the TRS Resource sets can also be configured through 4 bits of indications. The slot number is indicated by the explicit indication, which is 1 bit of indication. SIB messages need to carry 3+9+9+1+ (4+2+12+10+4+4+6+2)×11×6=2926 bits<2976 bits.
Optionally, the following configuration methods can also be included:
The TRS resource ID information field in the third parameter set is optional, occupying 0-2 bits. For example, if the quantity of slots in FR1 or FR2 clearly indicates the quantity of resources, the TRS resource ID information field can be a default or configured specifically.
As shown in
1. When the base station can configure up to 1 TRS-Resource set group, that is, the base station only needs 1-bit L1 signaling to indicate whether the terminal receives TRS, and the TRS Resource set group ID does not need to be indicated, that is, 0 bit.

When the TRS resource ID information field is the default, each TRS Resource set group supports a maximum of 6 TRS Resource sets which are indicated through 3 bits, and part of the TRS Resource sets can also be configured. The slot number is indicated through the explicit indication which is 1 bit of indication. The SIB messages need to carry 3+9+9+1+2+ (3+2+12+4+4+6+10×4)×6×6=2580 bits<2976 bits.
6. When the TRS resource ID information field is 2 bits, each TRS Resource set group supports a maximum of 6 TRS Resource sets which are indicated through 3 bits, and part of the TRS Resource sets can also be configured. The slot number is indicated through the explicit indication which is 1 bit of indication. The SIB messages need to carry 3+9+9+1+2+ (3+2+12+4+4+6+12×4)×6×6=2976 bits=2976 bits.
It should be noted that the beneficial effect of the application situation is that configuring TRS for the terminal in idle/inactive mode, which can accurately indicate TRS information when no more than 2 SIB messages carry the resource configuration information of the TRS.
The base station configures at least one TRS resource set group for a terminal in idle/inactive mode, and indicates at least one TRS resource set group through layer-one signaling.
Each TRS resource set group consists of a second parameter set exclusive to one or more TRS resource sets.
Specifically, the second parameter set exclusive to the one or more TRS resource sets includes at least one of the following: CSI-RS scrambling ID, Slot number, CSI-RS resource set ID, CSI-RS periodicity and offset value (periodicity AndOffset), QCL reference:
The third parameter set exclusive to the one or more TRS resource set groups 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 (periodicity AndOffset).
As shown in
1. When the base station can configure up to 1 TRS Resource set group, that is, the base station only needs 1-bit L1 signaling to indicate whether the terminal receives TRS, 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, which can indicate up to 89 beams through 7 bits, and the slot number is indicated through the explicit indication which is 1 bit of indication. Here, the periodicity and validity 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=2970 bits<2976 bits.
2. When the base station can configure up to 6 TRS Resource set groups, that is, the base station needs L1 signaling to indicate a maximum of 6 TRS Resource set groups, then the TRS Resource set group IDs need to be indicated by 3 bits. In this way, each TRS Resource set group can support a maximum of 16 TRS Resource sets which are indicated through 4 bits, and part of the TRS Resource sets can also be configured. The slot number is indicated through the explicit indication, which is 1 bit of indication. Here, the periodicity and validity 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=2916 bits<2976 bits.
As shown in
1. When the base station can configure up to 1 TRS Resource set group, that is, the base station only needs 1-bit L1 signaling to indicate whether the terminal receives TRS, and the TRS Resource set group ID does not need to be indicated, that is, 0 bit. Each TRS Resource set group supports a maximum of 65 TRS Resource sets, which can indicate up to 65 beams through 7 bits. The slot number is indicated through the explicit indication, which is 1 bit of indication. The SIB message needs to carry 9+9+1+2+(7+2+12+10+4+4+6)×65×1=2946 bits<2976 bits.
When the second resource set only has CSI-RS scrambling ID and QCL reference, the slot number is 0 bit. Each TRS Resource set group supports up to 128 TRS Resource sets, and can indicate up to 128 beams through 7 bits. The SIB message needs to carry 9+9+2+(7+10+6)×128×1=2964 bits<2976 bits.
2. When the base station can configure up to 6 TRS Resource set groups, that is, the base station needs L1 signaling to indicate a maximum of 6 TRS Resource set groups, then the TRS Resource set group IDs need to be indicated by 3 bits. In this way, each TRS Resource set group can support a maximum of 11 TRS Resource sets which are indicated through 4 bits, and part of the TRS Resource sets can also be configured. The slot number is indicated through the explicit indication, which is 1 bit of indication. The SIB message needs to carry 3+9+9+1+2+ (4+2+12+10+4+4+6)×11×6=2796 bits<2976 bits.
It should be noted that the beneficial effect of the application situation is that configuring TRS for the terminal in idle/inactive mode can be controlled within one SIB message, avoiding the generation method of resource configuration information for TRS applied in the connected mode exceeding the limit of data carried by the SIB message, and accurately indicating information of TRS.
The base station configures at least one TRS resource set group for the terminal in idle/inactive mode, and indicates at least one TRS resource set group through layer-one signaling.
The base station independently configures each TRS resource set group through the first parameter set exclusive to TRS resources, that is, each TRS resource set group only contains a first parameter set exclusive to one or more TRS resources, or, configures the sending resources corresponding to the TRS resource set group by simultaneously configuring the second parameter set exclusive to one or more TRS resource sets and the third parameter set exclusive to one or more TRS resource set groups.
Note: only one of two methods mentioned here can be configured on the base station side, but both methods cannot be used at the same time.
For configuring each TRS resource set group independently by the first parameter set exclusive to TRS resources, the first parameter set should at least include: CSI-RS scrambling ID, CSI-RS resource ID, QCL reference, CSI-RS periodicity and offset value (periodicity AndOffset), startingRB, nrofRBs, Validity time, Slot number, and powerControlOffsetSS.
It should be noted that the CSI-RS ResourceId information field in the third parameter set is optional. For example, 0˜2 bits. When the slot number in FR1 or FR2 clearly indicates the number of resources, the CSI-ResourceId information field can be the default or be configured specifically.
For configuring the TRS resource set groups by using at least the second parameter set exclusive to the TRS resource sets and the third parameter set exclusive to the TRS resource set groups, the second parameter set exclusive to the TRS resource sets should at least include: CSI-RS scrambling ID, CSI-RS resource set ID.

For configuring each CSI-RS/TRS resource set group independently by the first parameter set exclusive to the TRS resources, as shown in
1. When the base station can configure up to 1 TRS-Resource set group, that is, the base station only needs 1-bit L1 signaling to indicate whether the terminal receives CSI-RS/TRS, and the TRS-Resource set group ID does not need to be indicated, that is, 0 bit.
2. When the CSI-ResourceId information field needs to be indicated by 0˜Z1 bits, with an indication value of 0˜Z, the slot number is indicated through the explicit indication, which is 1 bit of indication. One TRS-Resource set group supports a maximum of 45 CSI-RS resources which are indicated through 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=2925 bits<2976 bits.
3. When the base station can configure up to 6 TRS-Resource set groups, that is, the base station needs L1 signaling to indicate a maximum of 6 TRS-Resource set groups, then the TRS-Resource set group IDs need to be indicated by 3 bits. One TRS-Resource set group supports up to 7 CSI-RS resources which are indicated by 3 bits. The amount of information that the SIB message needs to carry is 3+ (9+9+1+2+2+12+4+4+4+6+10+3)×7×6=2607 bits<2976 bits.
Note: Without being limited to the quantity of SIBs, specific configuration can be carried out based on the first parameter set, that is, parameter configuration can be carried out according to the CSI-RS parameter in the first parameter set, and transmission using more than one SIB can be performed.
For configuring the TRS resource set group by at least using the second parameter set exclusive to the TRS resource sets and the third parameter set exclusive to the TRS resource set groups, the implementation method is the same as that in the specific application situation 2, and the other implementation method is shown in
1. When the base station can configure up to 1 TRS-Resource set group, that is, the base station only needs 1-bit L1 signaling to indicate whether the terminal receives the CSI-RS/TRS, and the TRS-Resource set group ID does not need to be indicated, that is, 0 bit. Each TRS-Resource set group supports a maximum of 89 TRS Resource sets which are indicated by 7 bits, with only one CSI-RS/TRS Resource in each TRS Resource set. The slot number is indicated through the explicit indication, which is 1 bit of indication. The SIB message needs to carry 9+9+1+2+12+ (2+10+4+4+6+7)×89×1=2970 bits<2976 bits.
2. When the base station can configure up to 6 TRS-Resource set groups, that is, the base station needs L1 signaling to indicate a maximum of 6 TRS-Resource set groups, then the TRS-Resource set group IDs need to be indicated by 3 bits. Each TRS-Resource set group supports a maximum of 16 TRS-Resource sets which are indicated by 4 bits, with only one CSI-RS/TRS Resource in each TRS Resource set. The slot number is indicated through the explicit indication, which is 1 bit of indication. The SIB message needs to carry 3+9+9+1+2+12+ (2+10+4+4+6+4)×16×6=2916 bits<2976 bits.
It should be noted that the beneficial effect of the application situation is that configuring TRS for the terminal in idle/inactive mode can be controlled within one SIB message, avoiding the configuration of TRS in the connected mode exceeding the limit of data carried by the SIB message, and accurately indicating the information of the TRS.
It should be noted that for the discussion of configuration methods of TRS in idle/inactive mode, it has been decided to use the SIB signaling configuration, but there is no specific solution. When the RRC signaling configuration method for CSI-RS in the connected mode is directly used for SIB transmission, it cannot be guaranteed to be used before paging, leading to a decrease in energy efficiency gain. Moreover, reusing the RRC signaling configuration method for CSI-RS in the connected mode will result in significant SIB signaling overhead. The embodiments of the present disclosure provide binding of the resource configuration information of CSI-RS/TRS with the paging/SSB, which is beneficial for terminal energy conservation and can significantly reduce the system message signaling overhead.
