[0084] For ease of understanding, some of the contents involved in the embodiments of this application are described below:
[0085] 1. Preamble Allocation
[0086] The upper layer configures N (L1 parameter: SSB-per-rach-occasion) SSBs associated with a random access opportunity (RACH-Occasion, RO) (frequency domain) through the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB, and the number of contention-based preambles per SSB on each valid RO (L1 parameter: CB-preambles-per-SSB). RO can also be understood as the Physical Random Access Channel (PRACH) occasion. Among them, the configuration of N is:
[0087] If N<1, one SSB is mapped to 1 / N consecutive valid PRACH occasions (frequency domain) (for example: N=1 / 8, one SSB is mapped to 8 PRACH occasions), and R consecutive indexed preambles are mapped to SSB n, 0≤n≤N-1, and each valid PRACH occasion starts from preamble index 0 (for example: N=1 / 8, one SSB is mapped to 8 PRACH occasions, then there are 8 starting points with preamble index 0 in one SSB, because one PRACH occasion corresponds to a starting point with preamble index 0).
[0088] 2. Random Access (RA) Partition
[0089] Case 1: The features of protocols 15 (R15), R16, and R17 share a set of ROs, i.e., shared ROs.
[0090] Case 2: If it is a separate RO for RA partitioning, the preamble configured on the separate RO can only be associated with the R17 feature.
[0091] The Feature Combination Preamble Information Elements (IE) configures a set of preambles associated with a feature combination. Parameters can be provided in this IE or in the Random Access Common Configuration (RACH-ConfigCommon) or MsgA Common Configuration (MsgA-ConfigCommon). If the parameters provided in this IE are identified, the terminal applies the field value using the preamble in the feature combination preamble when performing random access; otherwise, the corresponding value identified in RACH-ConfigCommon or MsgA-ConfigCommon is applied.
[0092] Feature Combination Preambles-r17 configures the starting preamble position (startPreambleFoeThisPartition) and the number of preambles available for the feature (numberOfPreamblesForThisPartition) for each feature.
[0093] 3. Random Access Resource Selection for PRACH Repetition
[0094] For PRACH repetition, the UE needs to repeatedly send the preamble on multiple ROs at different locations in the time domain associated with the same SSB. The PRACH repetition count can be {2, 4, 8}. After determining the PRACH repetition count, the UE needs to determine the RO set. The number of valid ROs in the RO set is equal to the PRACH repetition count.
[0095] Assuming the number of PRACH repetitions is N1, the overall RO group determination rule within time window X is as follows: First, determine the starting RO of the first RO group, then determine the remaining N1-1 ROs in the first RO group. Then, determine the starting RO and its remaining ROs for the other RO groups in sequence. The remaining N1-1 ROs in each RO group are ROs associated with the same SSB, the same frequency position, and the same associated preamble set as the starting RO. After the first RO group is determined, the determination of the remaining RO groups is related to whether a time offset is configured. The purpose of introducing a time offset is to reduce the number of ROs detected on the network side, thereby alleviating pressure.
[0096] If no time offset is configured, for each SSB, the first valid RO within time window X is used as the starting RO of the first RO group. The first RO group is then determined based on the starting RO. The starting ROs of subsequent RO groups are then determined within time window X, excluding the already determined RO group, in ascending order of frequency domain position followed by time domain position. This is followed by further determination of subsequent RO groups. For example, assuming the PRACH repetition count is 2, for SSB #0, the RO group can be determined as shown in Figure 13.
[0097] If a time offset is configured, for each SSB, the first valid RO found within time window X, in the order of frequency domain first and time domain second, is used as the starting RO of the first RO group. The first RO group is then determined based on the starting RO. The starting ROs and corresponding RO groups of subsequent RO groups are then determined, excluding the determined RO group, in the order of frequency domain first and time domain second. The starting RO of the nth RO group associated with the same SSB at the same frequency position is the RO that is time offset from the starting RO of the n-1th RO group. The time offset is defined as the number of valid ROs associated with the same SSB in the time domain. For example, assuming the PRACH repetition count is 2 and time offset = 3, the RO group for SSB#0 can be determined as shown in Figure 14.
[0098] The following describes in detail the method for sending a signal, the method for receiving a signal, and the device provided in the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.
[0099] As shown in FIG2 , a method for sending a signal according to an embodiment of the present application includes:
[0100] Step 201: The terminal obtains first information from the first cell or the second cell;
[0101] Step 202: The terminal sends a first signal on a target resource according to the first information;
[0102] The first signal is used to trigger or request at least one of a system information block (SIB) adjustment, a synchronization signal block (SSB) adjustment, a random access opportunity (RO) adjustment, and a paging adjustment of the second cell;
[0103] The first information is used to determine at least one of the target resource, the first signal, and the second cell;
[0104] The target resource includes at least one of the following:
[0105] a target random access channel opportunity RO for random access of the second cell;
[0106] The first resource is a random access channel RACH resource used for random access segmentation;
[0107] The second resource is a resource independent of the RACH resource of the second cell and dedicated to sending the first signal.
[0108] In this way, the terminal can obtain the first information for determining at least one of the target resource, the first signal and the second cell from the first cell or the second cell in accordance with the above steps 201 and 202, and then send the first signal on the target resource according to the first information to trigger or request at least one of the SIB adjustment (adaptation), SSB adaptation, RO adaptation and paging (Paging) adaptation of the second cell, thereby meeting the communication needs between the terminal and the network.
[0109] The first cell is a non-energy-saving cell, and the second cell is an energy-saving cell (i.e., a cell that supports on-demand SIB1, or a cell that adopts some energy-saving technology). Alternatively, the cell can be understood as a base station, and the first cell is a non-energy-saving base station, and the second cell is an energy-saving base station; or, the first cell is a serving cell of the UE, or the first cell is the cell in which the UE is currently residing.
[0110] The first signal may be a UE uplink wake-up signal (Wake Up Signal, WUS). Specifically, the first signal may be in the form of a preamble sequence.
[0111] Wherein, the target resource is used to send a WUS, and the target resource may also be called a WUS occasion, or WO for short.
[0112] Adaptation may include switching the non-transmitting state of the corresponding object to the transmitting state, switching the transmitting cycle from a long cycle to a short cycle, and so on.
[0113] Optionally, when the WUS triggers or requests SIB adaptation of the second cell, it may trigger or request SIB1 adaptation.
[0114] Optionally, in this embodiment, the first information includes at least one of the following:
[0115] relevant information of the second cell;
[0116] configuration information of the first signal;
[0117] target threshold value information used for determining the target resource;
[0118] Target SSB identification;
[0119] Time Division Duplex (TDD) configuration information (TDD configuration);
[0120] Random access configuration information (RACH configuration);
[0121] Additional random access common configuration information (AdditionalRACH-ConfigCommon);
[0122] RO mask.
[0123] Optionally, the relevant information of the second cell includes at least one of the following:
[0124] Timing or System Frame Number (SFN);
[0125] a timing offset from the first cell;
[0126] SSB burst pattern and period;
[0127] SSB transmit power (tx power);
[0128] Timing advance offset (TA offset);
[0129] The frequency of the second cell.
[0130] Here, the second cell is also referred to as the target cell, and the related information of the second cell is also referred to as the target cell information. The SSB tx power is used to calculate the path loss (PL) and the transmit power of the WUS.
[0131] Optionally, the configuration information of the first signal includes at least one of the following:
[0132] Time-frequency domain resource allocation;
[0133] Preamble-related configuration.
[0134] Among them, the time-frequency domain resource configuration can be the relevant information of the time domain or frequency domain used by WUS transmission configured on the network side; the preamble related configuration can be the relevant information of the preamble configured on the network side for WUS transmission, such as the preamble configuration of WUS.
[0135] Optionally, the preamble-related configuration includes at least one of the following:
[0136] Preamble format (WUS Preamble format);
[0137] Number of repeated transmissions, that is, the number of times WUS is repeatedly sent;
[0138] WUS occasion pattern for WUS repetition;
[0139] The first time domain offset is used to indicate the number of first signal opportunities WO between adjacent target resource groups associated with the same SSB;
[0140] The second time domain offset is used to indicate the number of WOs between adjacent target resource groups;
[0141] Preamble root sequence;
[0142] The number of target preambles;
[0143] The start identifier of the target preamble;
[0144] The end marker of the target preamble;
[0145] The number of SSBs associated with a WO, and the number of preambles associated with each SSB;
[0146] Feature combination preamble configuration (FeatureCombinationPreambles);
[0147] Features in feature combinations (FeatureCombination);
[0148] Feature Priorities.
[0149] The WUS occasion pattern for WUS repetition is used to determine the WUS occasion pattern for sending WUS repetitions, and specifically may include but is not limited to the starting number and quantity of available occasions in an increasing order in the time domain or in an increasing order in the frequency domain.
[0150] The first time domain offset is the number of WOs spaced between two adjacent target resource groups (WUS occasion groups). Of course, the two WUS occasion groups and the spaced WOs are associated with the same SSB.
[0151] The second time domain offset is the number of WOs between two adjacent target resource groups (WUS occasion groups). The second time domain offset is applicable to the case where SSB is not associated with WO.
[0152] The Preamble root sequence may be shared by multiple cells or independent, and is different from the root sequence used by conventional RACH.
[0153] The target number of preambles refers to the total number of preambles used for WUS transmission. For example, if a preamble for a new feature (such as the Network Energy Saving (NES) feature) is added to the 64 preambles configured by Radio Resource Control (RRC), then if the NES preamble is the target preamble, the target number of preambles is the total number of NES preambles (totalNumberOfNES-Preambles). totalNumberOfNES-Preambles is a new RRC parameter.
[0154] Continuing with the previous example, when the NES feature is added and NES Preamble is the target preamble, the start identifier of the target preamble can be the start identifier of the NES Preamble (NES-PreambleStartIndex). NES-PreambleStartIndex is a new RRC parameter.
[0155] Among them, the end identifier of the target preamble code is similar to the start identifier of the target preamble code, and will not be repeated here.
[0156] Among them, the number of SSBs associated with the WO and the number of preambles associated with each SSB can be configured in the same way as in the previous example: ssb-perWUS-OccasionAndNES-PreamblesPerSSB.
[0157] Among them, FeatureCombinationPreambles at least includes the starting preamble position (startPreambleFoeThisPartition) corresponding to each feature or one or more feature combinations, the number of preambles available for the feature (numberOfPreamblesForThisPartition), the shared RO mask identifier (ssb-SharedRO-MaskIndex), and the SSB target threshold value (rsrp-ThresholdSSB) referenced when selecting the RO corresponding to the feature. Of course, FeatureCombinationPreambles can only include IE in the existing protocol, which will not be repeated here.
[0158] Among them, FeatureCombination, continuing the above example, when the NES feature is added, FeatureCombination includes the NES feature.
[0159] FeaturePriorities is used to determine which feature has a higher priority among multiple features, and the UE selects appropriate RA resources based on the feature priority.
[0160] Optionally, the target threshold value information includes at least one of the following:
[0161] A first threshold value, where the first threshold value is a SSB target threshold value referenced when randomly accessing and selecting an RO;
[0162] a second threshold value, where the second threshold value is an SSB target threshold value referenced when sending the first signal for a first purpose, where the first purpose is to trigger or request SIB adjustment of the second cell;
[0163] a third threshold value, where the third threshold value is an SSB target threshold value referenced when sending the first signal for a second purpose, where the second purpose is to trigger or request SSB adjustment of the second cell;
[0164] a fourth threshold value, where the fourth threshold value is an SSB target threshold value referenced when sending the first signal for a third purpose, where the third purpose is to trigger or request RO adjustment of the second cell;
[0165] A fifth threshold value, wherein the fifth threshold value is an SSB target threshold value referenced when sending the first signal for a fourth purpose, and the fourth purpose is to trigger or request paging adjustment of the second cell.
[0166] The first threshold value may be rsrp-ThresholdSSB, which is a target threshold value used for selecting RO when sending Msg1 and is an RRC parameter in the existing protocol.
[0167] The second threshold value may be a new RRC parameter, such as rsrp-ThresholdSSBforSIB1Triggering.
[0168] The third threshold value may be a new RRC parameter, such as rsrp-ThresholdSSBforSSBAdaptation.
[0169] The fourth threshold value may be a new RRC parameter, such as rsrp-ThresholdSSBforROAdaptation.
[0170] The fifth threshold value may be a new RRC parameter, such as rsrp-ThresholdSSBforPagingAdaptation.
[0171] Optionally, in this embodiment, if the first information includes a target SSB identifier (index), the target SSB index may be used to determine whether the RO associated with the target SSB index may be used to send the WUS.
[0172] Optionally, in this embodiment, if the first information includes random access configuration information, the random access configuration information (RACH resource configuration) may include RO configuration and preamble configuration. The RACH resource configuration is the RACH resource configuration of the target cell.
[0173] Optionally, the random access configuration information includes at least one of a random access common configuration (rach-configCommon) and a random access generic configuration (RACH-ConfigGeneric);
[0174] The random access public configuration includes at least one of the following:
[0175] Total number of random access preambles (totalNumberOfRA-Preambles);
[0176] The number of SSBs associated with each RO and the number of preambles associated with each SSB (ssb-perRACH-OccasionAndCB-PreamblesPerSSB);
[0177] Physical random access channel PRACH root sequence index (prach-RootSequenceIndex);
[0178] The SSB target threshold value used for random access selection of RO (such as rsrp-ThresholdSSB);
[0179] The random access general configuration includes at least one of the following:
[0180] PRACH configuration index (prach-ConfigurationIndex);
[0181] Frequency division multiplexing (FDM) configuration (msg1-FDM) of the first contention-based random access message Msg1;
[0182] The frequency domain starting position of Msg1 (msg1-FrequencyStart);
[0183] Preamble received target power (preambleReceivedTargetPower);
[0184] Power ramping step (powerRampingStep).
[0185] Among them, prach-ConfigurationIndex is used for time domain configuration and preamble format configuration.
[0186] Optionally, in this embodiment, if the first information includes an RO mask, the RO mask may be used to determine an RO among ROs associated with an SSB that may be used for WUS transmission.
[0187] Optionally, the RO mask includes one of the following:
[0188] The first indication information is used to indicate the starting identifier and quantity of one or more ROs allowed to send the first signal in the RO associated with each SSB; wherein, in the RO associated with each SSB, the identifiers of the ROs are numbered in the order of frequency domain first and time domain second;
[0189] The second indication information is used to indicate the parity of the identifiers of one or more ROs allowed to send the first signal in the RO associated with each SSB;
[0190] The third indication information is used to indicate the number of one or more ROs allowed to send the first signal in the RO associated with each SSB, and the starting RO is the default RO.
[0191] For each SSB, all ROs associated with the SSB can be determined first, and then these ROs are numbered sequentially in the frequency domain first and then the time domain, and the number is used as the RO identifier (occasion index). Therefore, the first indication information may include the starting identifier and number of ROs. Then, among all ROs of an SSB, the number of consecutive ROs starting from the starting identifier is determined to be the ROs that can be used to send WUS. For example, if occasion index = 1 and quantity = 4, then starting from occasion index = 1, in the order of frequency domain first and then time domain, the four consecutive ROs can be used to send WUS.
[0192] The second indication information indicates, by indicating the parity of the RO identifier, one or more ROs associated with each SSB that are allowed to transmit the first signal. For example, if the second indication information indicates that the RO identifier is an odd number, then ROs with odd occasion indices can be used to transmit the WUS. The identifier is also obtained in the manner described above.
[0193] Of course, for each RO associated with the SSB, the identifiers of one or more ROs that are allowed to send the first signal may also be directly and explicitly indicated.
[0194] Based on the pre-setting of the default RO as the starting RO, the third indication information only needs to include the number of ROs. Then, among all ROs in an SSB, the ROs that are consecutively connected starting from the default RO are determined to be ROs that can be used to send WUSs. For example, if the default RO is the first RO and the number is 4, then starting from the first RO, the four consecutive ROs can be used to send WUSs.
[0195] In addition, for the target resource including the target RO for random access of the second cell, optionally, in this embodiment, the target RO for random access of the second cell is determined by a measurement result of a reference signal of the second cell; or,
[0196] The target RO of the second cell for random access is determined by an RO mask; or,
[0197] The target RO for random access of the second cell is the RO associated with the target SSB identifier;
[0198] The RO mask and the target SSB identifier are included in the first information or configured by the network side.
[0199] That is, the target RO for random access of the second cell can be determined by the measurement result of the reference signal of the second cell, the RO mask or the target SSB identifier, and the UE can send a WUS on these target ROs. The RO mask or target SSB identifier used can be included in the first information as described above, or configured on the network side.
[0200] Optionally, the target RO for random access of the second cell is the RO corresponding to the reference signal with the best measurement result among the reference signals of the second cell; or,
[0201] The target RO for random access of the second cell is the RO corresponding to the reference signal in the reference signal of the second cell whose measurement result is greater than the target threshold value; wherein the target threshold value is configured by the network side or included in the first information, and multiple target threshold values are mapped one-to-one to first signals for different purposes.
[0202] In other words, in one approach, when determining the target RO for random access in the second cell based on the measurement results of the reference signal of the second cell, the measurement results of different reference signals of the second cell are compared, and the RO corresponding to the reference signal with the best measurement result is determined as the target RO. Taking the measurement quantity RSRP as an example, the measurement result includes the RSRP values of multiple reference signals of the second cell. The best measurement result, i.e., the largest RSRP, is used as the target RO. Of course, for different measurement quantities, the smaller the measurement quantity, the better the measurement result. In this case, the RO corresponding to the reference signal with the smallest measurement quantity is used to determine the target RO.
[0203] In one approach, when determining the target RO for random access of the second cell based on the measurement results of the reference signal of the second cell, the measurement results of each reference signal of the second cell are compared with the target threshold value to determine that the RO corresponding to the reference signal of the second cell whose measurement result is greater than the target threshold value is the target RO. Taking the measurement quantity RSRP as an example, the target threshold value is rsrp-ThresholdSSB, and the measurement results include the RSRP values of multiple reference signals of the second cell, then the RO corresponding to the reference signal whose RSRP is greater than rsrp-ThresholdSSB among the multiple reference signals of the second cell is the target RO. Of course, for different measurement quantities, there is also a case where the smaller the measurement quantity value, the better the measurement result, that is, the RO corresponding to the reference signal whose measurement quantity is less than the target threshold value needs to be determined as the target RO.
[0204] Since WUSs with different purposes (functions) may be configured with different target thresholds, as shown in the target threshold information in the first information, the target resources determined for WUSs with different purposes may be different.
[0205] In this embodiment, the reference signal may be SSB.
[0206] When the target RO for random access of the second cell is determined by the RO mask, optionally, in this embodiment, the RO mask is used to indicate one or more ROs among the ROs associated with each SSB that are allowed to send the first signal, or to indicate one or more ROs among the ROs associated with the target SSB identifier that are allowed to send the first signal.
[0207] Specifically, the RO mask is used to indicate the RO set or subset of the ROs associated with each SSB that are allowed to send WUS, and the RO set or subset includes one or more ROs; or, it is used to indicate the RO set or subset of the ROs associated with the target SSB identifier that are allowed to send WUS, and the RO set or subset includes one or more ROs.
[0208] Optionally, the number of the RO masks is greater than or equal to 1, and when there are multiple RO masks, the multiple RO masks are used to determine one or more ROs of the first signal for different purposes.
[0209] That is, when there are multiple RO masks included in the first information or configured on the network side, the multiple RO masks can be used to determine one or more ROs of WUSs with different purposes.
[0210] Optionally, in this embodiment, the second resource includes multiple sets of resources of the first signal for different purposes.
[0211] That is, the resources independent of the RACH resources of the second cell and dedicated to sending the WUS may be multiple sets of resources, each corresponding to WUS sending for a different purpose.
[0212] Optionally, in this embodiment, there is no mapping relationship between SSB and RO for the second resource.
[0213] In this embodiment, the configuration of the first resource and the second resource may be included in the first information or configured by the network side.
[0214] Optionally, in this embodiment, the first signal is a preamble configured by the network side and used for sending the first signal, and the target preamble includes at least one of the following:
[0215] Preamble not used for random access;
[0216] Preamble used for random access.
[0217] That is, the preamble sent by the WUS is one of the target preambles configured by the network side and available for WUS transmission. The target preamble can be a preamble not used for random access or a preamble used for random access.
[0218] The preamble not used for random access may be a preamble independent of the preamble used for random access. The preamble used for random access may be a preamble included in the RA preamble and associated with the feature combination.
[0219] Optionally, the identifier of the preamble code not used for random access is located before or after the identifier of the preamble code used for system information request.
[0220] That is, in the preamble configuration, the identifier of the preamble not used for random access may be before or after the identifier of the preamble used for system information request (SI request), for example, as shown in FIG3 or FIG4.
[0221] Optionally, the identifier of the preamble used for random access is located before the identifier of the non-contention-based preamble and after the identifier of the preamble used for the coverage enhancement feature.
[0222] That is, in the preamble configuration, the identifier of the preamble used for random access is located before the identifier of the non-contention-based preamble (such as the CF preamble) and after the identifier of the preamble used for the coverage enhancement feature (such as the preamble associated with the coverage enhancement feature), as shown in Figure 5.
[0223] In addition, the terminal sending a first signal on the target resource according to the first information includes:
[0224] The terminal determines a plurality of target resource groups in the target resources, and repeatedly sends the first signal in the plurality of target resource groups; or,
[0225] The terminal repeatedly sends the first signal on the target resource corresponding to the transmission pattern within the specific time window according to the transmission pattern and the number of repeated transmissions in the specific time window.
[0226] That is, when repeated WUS transmission is required, one approach is to determine multiple target resource groups within the target resources and then repeatedly transmit the WUS within these multiple target resource groups. In this case, the number of WOs included in a target resource group is equal to the number of repeated transmissions of the WUS. Alternatively, the network side configures a transmission pattern for a specific time window and a repetition count N, where the transmission pattern is a pattern of WOs available within the specific time window and is used to indicate the WOs to which the WUS is to be repeatedly transmitted. Within the specific time window, the WUS is then transmitted N times repeatedly at the corresponding WOs directly according to the transmission pattern. For example, the transmission pattern indicates the same number of WOs as the number of repeated transmissions, and the period is T.
[0227] Optionally, in this embodiment, the terminal repeatedly sending the first signal in the multiple target resource groups includes:
[0228] The terminal determines the starting WO and remaining WOs of the first target resource group within a specific time window;
[0229] In a case where a mapping relationship exists between the target resource and the SSB, the terminal determines, within the specific time window, the start WO and the remaining WO of the remaining target resource groups in the multiple target resource groups according to the first time domain offset; or
[0230] When there is no mapping relationship between the target resource and the SSB, the terminal determines, within a specific time window, the start WO and the remaining WOs of the remaining target resource groups in the multiple target resource groups according to the second time domain offset;
[0231] The number of remaining WOs in each target resource group is equal to the number of repeated transmissions minus 1.
[0232] In other words, the terminal first determines the starting WO and remaining WO of the first target resource group within a specific time window to obtain the first target resource group. Then, based on whether there is a mapping relationship between the target resource and the SSB, the terminal uses the applicable time domain offset to determine the starting WO and remaining WO of the remaining target resource groups in multiple target resource groups to obtain the remaining target resource groups. This allows repeated transmission of WO in multiple target resource groups.
[0233] The number of WOs included in each target resource group is equal to the number of repeated transmissions. After determining the starting WO, (number of repeated transmissions - 1) remaining WOs need to be determined.
[0234] The starting WO of the first target resource group may be the first WO within a specific time window.
[0235] Of course, if the first time domain offset and the second time domain offset are not configured, when determining the starting WO of the remaining target resource group, within a specific time window, the starting WO of the remaining target resource group is determined in the order of increasing frequency domain position first and then increasing time domain position.
[0236] Optionally, when the target resource is associated with an SSB, the multiple target resource groups are associated with the same SSB.
[0237] For example, when the target resource is associated with SSB, if multiple target resource groups are associated with SSB1, the starting WO of the first target resource group can be the first WO associated with SSB1 within a specific time window, and the remaining WOs are the remaining WOs (number of repeated transmissions - 1) associated with SSB1 starting from the starting WO and increasing in time domain position.
[0238] The following describes the application of the method of the embodiment of the present application in conjunction with specific scenarios:
[0239] Example 1: The target resource is a target RO for random access of the second cell, and the target RO for random access of the second cell is determined by a measurement result of a reference signal of the second cell.
[0240] Step 1: The network side (such as the first cell) sends the first information to the UE. The first information includes at least one or more of the following: TDD configuration; ssb-perWUS-OccasionAndNES-PreamblesPerSSB; RACH resource configuration; WUS preamble configuration.
[0241] Among them, the RACH resource configuration includes at least: rach-configCommon and RACH-ConfigGeneric; rach-configCommon includes totalNumberOfRA-Preambles, ssb-perRACH-OccasionAndCB-PreamblesPerSSB, prach-RootSequenceIndex, rsrp-ThresholdSSB; RACH-ConfigGeneric includes prach-ConfigurationIndex (time domain configuration and preamble format configuration), msg1-FDM (frequency domain configuration), msg1-FrequencyStart (frequency domain configuration), preambleReceivedTargetPower, and powerRampingStep.
[0242] The WUS preamble configuration includes: a start identifier of a target preamble (such as a start preamble index) and the number of target preambles (such as the number of WUS preambles).
[0243] Among them, the preamble that can be used to send WUS is shown in Figures 3, 4, and 5.
[0244] Case A: The preamble that can be used to send WUS is considered an NES feature and arranged together with the preamble of the R17 feature combination, as shown in Figure 5. The preamble configuration of WUS can follow the FeatureCombinationPreambles-r17 configuration of R17, as shown below;
[0245] FeatureCombinationPreambles-r17::=SEQUENCE{
[0246] featureCombination-r17,
[0247] startPreambleForThisPartition-r17 INTEGER(1..64),

[0252] featureSpecificParameters-r17 SEQUENCE{
[0253] rsrp-ThresholdSSB-r17 RSRP-Range OPTIONAL,--Need R
[0254] rsrp-ThresholdMsg3-r17 RSRP-Range OPTIONAL,--Need R
[0255] --Editor's note:TBD if this parameter indeed can be partition-specific.
[0256] messagePowerOffsetGroupB-r17 ENUMERATED{minusinfinity,dB0,dB5,dB8,dB10,dB12,dB15,dB18}OPTIONAL,--Need R
[0257] ra-SizeGroupA-r17 ENUMERATED{b56,b144,b208,b256,b282,b480,b640,b800,b1000,b72,spare6,
[0258] spare5,spare4,spare3,spare2,spare1}OPTIONAL,--Need R
[0259] deltaPreamble-r17 INTEGER(-1..6)OPTIONAL--Need R
[0260] }
[0261] FeatureCombinationPreambles-r17 contains the starting preamble index and the number of WUS preambles corresponding to the NES feature. If you want to extend it to network energy saving, you can continue to use this architecture and only need to add the NES feature to FeatureCombination, as shown below:
[0262] FeatureCombination-r17::=SEQUENCE{
[0263] redCap ENUMERATED{true}OPTIONAL,--Need R
[0264] smallData ENUMERATED{true}OPTIONAL,--Need R
[0265] sliceGroup SliceGroupList-r17 OPTIONAL,--Need R
[0266] covEnh ENUMERATED{true}OPTIONAL,--Need R
[0267] NES ENUMERATED{true}OPTIONAL,--Need R
[0268] ...
[0269] }
[0270] Case B: Independent of the preamble of the R17 feature combination, in addition to the RA preamble, the target preamble (which can be used for the WUS preamble) is determined according to the starting position of the preamble index and / or the number of preambles, as shown in FIG3 or FIG4.
[0271] In case B, you can configure only the number of WUS preambles, W, and obtain the starting preamble index by using 64-W. Alternatively, you can directly configure the starting preamble index.
[0272] When there is a mapping relationship between RO and SSB, and between the target preamble (WUS preamble) and SSB, the mapping rule may refer to the ssb-perRACH-OccasionAndCB-PreamblesPerSSB contained in the RACH configuration of the target cell contained in the first information, or may refer to the parameters configured in the first information specifically for WUS transmission, including the number of SSBs associated with the WO and the number of preambles associated with each SSB (also known as the number of SSBs per WO and the number of WUS preambles per SSB), which can be expressed by the new RRC parameter ssb-perWUS-OccasionAndNES-PreamblesPerSSB.
[0273] Step 2: Based on the SSB measurement result, the UE selects the RO corresponding to the SSB whose measurement result is greater than rsrp-ThresholdSSB to send a WUS, such as Msg1. As shown in Figure 6, the RO corresponding to SSB6 is selected to send a WUS. Optionally, the WUS preamble can be determined based on the first information including the starting preamble index and the number of WUS preambles (such as totalNumberOfWUSPreambles).
[0274] Step 3: The network side sends SIB1 according to the direction of the SSB associated with the WUS RO sent by the UE; or, the network side sends SIB1 according to the direction of the SSB associated with the WUS RO sent by the UE and multiple SSBs near the SSB.
[0275] Example 2: The target resource is a target RO for random access of the second cell, and the target RO for random access of the second cell is configured by the network side.
[0276] In this example, since the RO associated with the target SSB can be used for both sending WUS and performing random access, it is necessary to separate the two functions in the preamble dimension.
[0277] Step 1: The network side sends the first information to the UE. The first information includes TDD configuration, ssb-perWUS-OccasionAndNES-PreamblesPerSSB, target SSB index, RO mask, RACH resource configuration of the target cell, and WUS preamble configuration.
[0278] Among them, the first information includes the target SSB index, which can be understood as the RO corresponding to the target SSB index configured by the network side can be used to send WUS, and the UE can only send WUS in the RO corresponding to the target SSB index. The first information includes an RO mask, which can be a mask index, to indicate which ROs or sets or subsets of ROs can be used to send WUS. Each mask index represents a selected valid RO. For example, three RO masks are shown in Figures 7, 8 and 9. If the RO mask is configured, Figure 7 means that the first and third ROs in the RO associated with each SSB can be used to send WUS; Figure 8 means that the second and fourth ROs in the RO associated with each SSB can be used to send WUS; Figure 9 means that the third and fourth ROs in the RO associated with each SSB can be used to send WUS. If both the RO mask and the target SSB index are configured, the UE can only determine the RO to send WUS based on the RO mask based on the RO associated with the target SSB index.
[0279] Among them, the RACH resource configuration of the target cell includes at least: rach-configCommon and RACH-ConfigGeneric; rach-configCommon includes totalNumberOfRA-Preambles, ssb-perRACH-OccasionAndCB-PreamblesPerSSB, prach-RootSequenceIndex, rsrp-ThresholdSSB; RACH-ConfigGeneric includes prach-ConfigurationIndex (time domain configuration and preamble format configuration), msg1-FDM (frequency domain configuration), msg1-FrequencyStart (frequency domain configuration), preambleReceivedTargetPower, powerRampingStep.
[0280] The WUS preamble configuration includes: a start identifier of a target preamble (such as a start preamble index, which can also be understood as a start position of the preamble) and the number of target preambles (such as the number of WUS preambles, or the number of preambles).
[0281] Step 2: The UE sends a WUS (Msg1) on the RO that can send the WUS according to the first information (such as the target SSB index or the RO mask). Optionally, the WUS preamble can be determined according to the first information and the mapping between the preamble and the SSB.
[0282] Step 3, send SIB1 direction:
[0283] If the UE sends a WUS on the RO associated with the target SSB index, the base station sends SIB1 in all directions after receiving the WUS; or the network side sends SIB1 in the direction of the target SSB;
[0284] If the UE sends the WUS on the RO associated with the RO mask, the network side determines the direction of sending the SIB1 according to the SSB associated with the RO sent by the UE.
[0285] Example 3: The target resource is a second resource, which is independent of the RACH resource of the second cell and is dedicated to sending the first signal, and the second resource is not mapped to the SSB.
[0286] In this example, as shown in FIG10 , the second resource is called a WUS occasion or a separate RO. This WUS occasion is only used for sending a WUS. There is no need to divide the preamble into multiple functions. All preambles (WUS) are used to trigger the sending of SIB1.
[0287] If there is no mapping between SSB and WUS occasions on these WUS occasions, that is, these WUS occasions are not associated with SSBs, all WUS occasions will not have any uplink or downlink directionality implications. In this case, since WO is not associated with SSBs, the WUS configuration (including WUS time-frequency resource configuration) can be valid for multiple cells, and the WUS configuration of cells within an area is the same.
[0288] Step 1: When the UE cannot stay in the current cell and needs to reselect the cell, if the UE has WUS configured and finds that the energy-saving cell does not send SIB1, the UE sends WUS omnidirectionally to the energy-saving cell to trigger the energy-saving cell to send SIB1 to determine whether the energy-saving cell can be stayed.
[0289] Step 2: The energy-saving cell receives the WUS sent by the UE and sends WUS feedback to the UE, where the WUS feedback carries the SIB1 direction information or the SSB index information and the RAPID;
[0290] Step 3: UE omnidirectionally receives WUS feedback;
[0291] Step 4: After receiving the WUS feedback, the UE receives SIB1 according to the direction of the SSB index carried in the WUS feedback.
[0292] Example 4: The target resource is the first resource, which is a RACH resource used for random access segmentation, and there is a mapping relationship between the first resource and the SSB.
[0293] In this example, the first resource is called WUS occasion or separate RO, and this WUS occasion still has a mapping between SSB and WUS occasion.
[0294] Because R17 uses a separate RO for RA partition mechanism, this example extends the R17 framework. In R17, if separate RO for RA partitioning is used, the preamble configured on the separate RO can only be associated with R17 and R18 features. Part of the preamble can be used as a WUS preamble, as shown in Figures 11 and 12.
[0295] As shown in Figures 11 and 12, the allocation method for the two WUS preambles can refer to the configuration framework of R17 and add the NES feature to the feature combination; or separately configure the starting number of the preamble and the number of preambles.
[0296] Step 1: The UE sends a WUS to the energy-saving cell on the WUS occasion associated with the selected SSB according to the configuration of the first information and the SSB measurement result, to trigger the sending of SIB1 of the energy-saving cell. The first information includes: the RACH resource configuration of the target cell and the preamble configuration of the WUS.
[0297] Among them, the RACH resource configuration of the target cell includes at least: rach-configCommon and RACH-ConfigGeneric; rach-configCommon includes totalNumberOfRA-Preambles, ssb-perRACH-OccasionAndCB-PreamblesPerSSB, prach-RootSequenceIndex, rsrp-ThresholdSSB; RACH-ConfigGeneric includes prach-ConfigurationIndex (time domain configuration and preamble format configuration), msg1-FDM (frequency domain configuration), msg1-FrequencyStart (frequency domain configuration), preambleReceivedTargetPower, powerRampingStep.
[0298] The WUS preamble configuration includes: a start identifier of a target preamble (such as a start preamble index) and the number of target preambles (such as the number of WUS preambles).
[0299] Step 2: The UE receives the successfully triggered SIB1 according to the direction of the SSB associated with the RO that sent the WUS.
[0300] Example 5: Configuration combined with feature combination.
[0301] Add the NES feature to the FeatureCombination:
[0302] FeatureCombination-r19::=SEQUENCE{

[0306] covEnh ENUMERATED{true}OPTIONAL,--Need R
[0307] NES ENUMERATED{true}OPTIONAL,--Need R
[0308] }
[0309] In FeatureCombinationPreambles, configure the starting position of the preamble corresponding to the NES feature, the number of preambles, the RO mask, and the target threshold value, such as the RSRP threshold value used to select SSB:
[0310] FeatureCombinationPreambles-r19::=SEQUENCE{
[0311] featureCombination-r19 FeatureCombination-r19,
[0312] startPreambleForThisPartition-r19 INTEGER(1..64),
[0313] numberOfPreamblesForThisPartition-r19 INTEGER(1..64),
[0314] ssb-SharedRO-MaskIndex-r19 INTEGER(1..15)OPTIONAL,--Need R
[0315] featureSpecificParameters-r19 SEQUENCE{
[0316] rsrp-ThresholdSSB-r19 RSRP-Range OPTIONAL,--Need R
[0317] --Editor's note:TBD if this parameter indeed can be partition-specific.
[0318] }
[0319] Example 6: Multiple RO masks are configured to determine one or more ROs of WUSs with different purposes.
[0320] Each SSB is associated with 8 ROs. The network sends the first message to the UE. The first message includes four RO masks (indexes), which is also called configuring four RO masks (indexes). Each RO mask corresponds to a WUS with different uses. The optional RO set sent is:
[0321] Configure the RO mask index for the first purpose, that is, PRACH Mask Index for SIB1 transmission = 1, which means that the first RO among the 8 ROs associated with an SSB can be used to send WUS to trigger the transmission of SIB1;
[0322] Configure the RO mask index for the second purpose, that is, PRACH Mask Index for SSB adaptation = 2, which means that the second RO among the 8 ROs associated with an SSB can be used to send WUS to trigger SSB adaptation;
[0323] Configure the RO mask index for the third purpose, that is, PRACH Mask Index for SIB1 transmission = 3, which means that the third RO among the 8 ROs associated with an SSB can be used to send WUS to trigger RO adaptation;
[0324] Configuring the RO mask index for the fourth purpose, that is, PRACH Mask Index for SIB1 transmission = 4, means that the fourth RO among the eight ROs associated with an SSB can be used to send WUS to trigger paging adaptation.
[0325] Example 7: WUS repetition.
[0326] If there is a mapping between WO and SSB, the rules for determining the WO to send WUS repetitions are the same as the rules for determining the PRACH repetition occasion, but the network side will configure WUS specific parameters for the UE, including at least the number of repeated transmissions (i.e., the number of WUS repetitions) and the first time domain offset (time offset for WUS). The first time domain offset is used to determine the number of WOs associated with the same SSB between two WO groups. Specifically:
[0327] Assume that the number of WUS repetitions is W (configured or indicated by the network side, and the RRC parameter can be reused (This parameter can also be independently configured). The target resource group (WO (WUS occasion) group) within a specific time window (time window X) is determined as follows: first, the starting WO of the first WO group is determined, followed by the remaining W-1 WOs in the first WO group; then, the starting RO and the remaining WOs of the other WO groups are determined in sequence. The remaining W-1 WOs in each WO group are associated with the same SSB, the same frequency position, and the same associated preamble set as the starting WO. After the first WO group is determined, the determination of the remaining WO groups is related to whether the first time domain offset is configured. The purpose of introducing the first time domain offset is to reduce the number of WOs detected on the network side to alleviate pressure.
[0328] If the first time domain offset is not configured, for each SSB, the first valid WO within time window X is used as the starting WO of the first WO group, and the first WO group is determined based on the starting WO. Then, for all WOs excluding the determined WO group, the starting ROs of subsequent WO groups are determined within time window X in ascending order of frequency domain position followed by time domain position, and subsequent WO groups are further determined.
[0329] If the first time domain offset is configured, for each SSB, the first valid WO found within time window X, in the frequency domain followed by the time domain, is used as the starting WO of the first WO group. The first WO group is then determined based on the starting WO. After excluding the determined WO group, the starting WOs of subsequent WO groups and the corresponding WO groups are determined in the frequency domain followed by the time domain. The starting WO of the nth WO group associated with the same SSB at the same frequency position is the WO that is the first time domain offset away from the starting WO of the n-1th WO group. The first time domain offset is defined as the number of WOs associated with the same SSB in the time domain.
[0330] Of course, if there is no mapping between the occasion for sending WUS and SSB, the WO (WUS occasion) group that can be used to send WUS repetition within the time window X is determined as follows:
[0331] Step 1: First determine the first WO group. The determination method is:
[0332] Starting from the first WO (the WO with the earliest time domain position and the lowest frequency domain position), N consecutive WUS occasions with increasing time domain positions are performed with the same frequency domain position;
[0333] Or starting from the first WO (the WO with the earliest time domain position and the lowest frequency domain position), N consecutive WUS occasions with increasing frequency domain positions with the same time domain position;
[0334] Or starting from the first WO (the WO with the earliest position in the time domain and the lowest position in the frequency domain), first increase the frequency domain and then increase the time domain for N consecutive WUS occasions;
[0335] Or the WO pattern configured on the network side contains N WUS occasions. The pattern can be configured by the network side, for example, WO with odd index or RO with even index can be used to send WUS repetition, or configure RO index.
[0336] Step 2: Then determine other WO groups in turn:
[0337] The starting WO of the nth WO group is the WO that is a second time domain offset from the starting WO of the n-1th WO group. The second time domain offset may be configured by the network side, for example, the first information includes the second time domain offset.
[0338] Of course, if there is no mapping between the occasion for sending WUS and SSB, the WO (WUS occasion) that can be used to send WUS repetition within the time window X is determined as follows:
[0339] The network side configures the transmission pattern (occasion pattern) that can be used to send WUS repetition within the time window X, as well as the number of repeated transmissions (ie, the number of WUS repetitions). The UE determines the corresponding occasion based on the network side configuration.
