Description

Technical Field

[0001] This document relates generally to wireless communications. Background Art

[0002] With the development of wireless communications, the utilization of broadband frequency resources and spatial resources has been further improved. In order to achieve efficient wireless communications, more flexible measurements / reporting are needed to enable gNB (next generation Node B) with "smart" scheduling. However, in order to support such flexible measurements, more signaling and measurement work is required on the user equipment (UE) side according to existing mechanisms (e.g., gNB triggered measurements). In addition, in order to support adaptation between different frequency resources (e.g., different bandwidth parts (BWP)), measurements need to be performed on large-scale resources, and the impact of radio frequency (RF) tuning may need to be considered during resource configuration for such measurements.

[0003] Furthermore, in the case of non-terrestrial networks with satellite services, such as high altitude pseudo satellites (HAPS) or air-to-ground (ATG), the above problems may become more serious. More specifically, the instantaneous service area of ​​a cell may be covered by a large number of beams, which sweep across the target area as the satellite moves along the satellite orbit. In order to mitigate the interference that occurs, resource reuse between beams can be adopted. For example, the beams are mapped to different frequency regions and / or different polarization modes. Figures 1A to 1D An example of a resource reuse pattern between beams B1 to B7 covering adjacent service areas is shown. Figure 1A In , beams B1 to B2 are configured to the same frequency region and the same polarization mode. Figure 1B In , beams B1 and B2 are configured to the same frequency region and different polarization modes. Figure 1C In , beams B1 to B7 are configured in different frequency regions and the same polarization mode. Figure 1D In the example, beams B1 to B7 are configured in different frequency regions and different polarization modes. When resource reuse between beams is adopted, the resource configuration and / or triggering conditions should be carefully considered.

[0004] In addition, the coverage area of ​​a single satellite beam may be hundreds of kilometers in diameter or even larger. In such a large coverage area, the number of user equipment (UE) will be huge. If the network notifies the UEs of the change in service frequency one by one, the signaling overhead will be very high due to the huge number of UEs. Summary of the invention

[0205] In the present disclosure, a reference signal group may refer to a resource set (eg, a resource group), and multiple resource groups may be further organized into different resource settings. That is, a resource setting may include one or more resource groups.

[0206] In an embodiment, the BS configures resources of one or more RSs to the UE to confirm the channel condition. For example, the BS may transmit a configuration to the UE, wherein the configuration indicates resources of one or more RSs.

[0207] In an embodiment, the configuration indicates one or more resource reuse patterns of one or more RSs. The resource reuse pattern refers to the resources for sending / receiving the associated RS (or channel). For example, the resource reuse pattern indicates (e.g., refers to or is determined to be) at least one of the following:

[0208] Frequency region,

[0209] Polarization mode,

[0210] A combination of frequency region and polarization mode, or

[0211] Space resources.

[0212] Please note that the frequency region and / or polarization mode may be described (e.g., indicated) only by a resource index or indicator. For example, the frequency region may be indicated by a BWP Id or a carrier frequency ID. In an embodiment, the polarization mode may be indicated by an indicator (e.g., 0 refers to polarization mode 1, 1 refers to polarization mode 2, etc.).

[0213] In an embodiment, the polarization mode may refer to the following exemplary polarizations: right-hand circular polarization, left-hand circular polarization, linear polarization, or cross polarization.

[0214] In an embodiment, the spatial resources may refer to resources for different antenna ports, resources for different antennas, resources with different quasi-co-site (QCL) reference signals for the QCL type (eg, type D) in the associated QCL indication.

[0215] After receiving the configuration, the UE transmits one or more reports to the BS based on the configuration. For example, the UE may perform measurements based on the configuration and transmit one or more reports with measurement results to the BS based on the configuration.

[0216] The following discusses RS resource configuration (ie, measurement), conditions for triggering measurement, and reporting behavior.

[0217] Example 1: Resource configuration for measurement

[0218] In this embodiment, resource configuration is used as an example to explain in detail:

[0219] a) How to organize RS for measurement

[0220] For example, how to map RS to one or more frequency regions and / or one or more polarization modes

[0221] b) Specific requirements for RS configuration / transmission / reception

[0222] Case-1: At least one RS is configured to the UE within a resource group (eg, resource set), where each RS has its own resources. In an embodiment, the number of RSs configured within a single resource group is a positive integer N.

[0223] In an embodiment, the BS configures the resources (eg, resource reuse pattern) of each RS. In other words, the BS explicitly indicates the resources of each RS through configuration.

[0224] In an embodiment, each RS is transmitted in a single frequency region. In this embodiment, the frequency region corresponding to each RS can be configured to the UE. For example, the index of the frequency region can be configured for each RS.

[0225] In an embodiment, each RS may have its own polarization mode. In this case, the polarization mode corresponding to each RS may be configured to the UE.

[0226] In an embodiment, each RS may have its own frequency region and polarization mode. In this embodiment, the frequency region index and polarization mode corresponding to each RS are configured to the UE.

[0227] In an embodiment, the BS may configure an identification (ID) for each RS, wherein each ID is associated with a specific resource reuse pattern.

[0228] In an embodiment, the ID is a logical ID.

[0229] In an embodiment, the ID is derived from other sources. For example, the ID can be derived in a similar manner to a cell ID, which is obtained based on the detection of a secondary synchronization signal (SSS). In another example, the ID can be derived in a similar manner to a synchronization signal block (SSB) index, which is derived by decoding the corresponding information within the SSB.

[0230] In an embodiment, the ID may be determined by at least one of the following:

[0231] a) Configuration parameters,

[0232] b) Frequency region (eg, index or ID of the frequency region)

[0233] c) Polarization mode (eg, index or ID of the polarization mode)

[0234] In an embodiment, the configured parameters indicate which resource reuse mode is supported. In one example, the configured parameters may indicate whether polarization reuse is enabled. In another example, the configured parameters may indicate whether frequency reuse is enabled. In yet another example, the configured parameters may indicate whether the beam (e.g., Figures 1A to 1D ) between the resource reuse patterns enabled.

[0235] In an embodiment, the ID is associated with a resource reuse pattern (eg, polarization pattern and / or frequency region).

[0236] Figure 4 FIG. 1 shows a schematic diagram of an ID according to an embodiment of the present application. Figure 4 In FIG. 1 , each of IDs L0, L1, L2 and L3 is associated with its own frequency region and polarization mode. L0 is associated with frequency region ID F1 and polarization mode ID P1, L1 is associated with frequency region ID F2 and polarization mode ID P2, and so on.

[0237] In an embodiment, the resource reuse pattern of an ID is determined based on the maximum number of supported resource reuse patterns (eg, the maximum index number of the resource reuse pattern) and the ID.

[0238] In an embodiment, the resource reuse pattern of each ID may be determined by:

[0239] mod(l,N+1)+1

[0240] Where l is the ID, mod(X,Y) is the function of the modulo operation of X divided by Y, and N is the maximum index number of the resource reuse pattern.

[0241] Figure 5FIG. 1 is a schematic diagram showing an ID and a corresponding beam ID according to an embodiment of the present application. Figure 5 In the example, the ID implicitly refers to the beam IDs B0 to B11. In addition, the resource reuse pattern indicates the frequency region ID, and 3 frequency region IDs F1, F2, and F3 are supported. In this embodiment, the resource reuse pattern of each ID can be determined by mod(l,N+1)+1. Note that the index of the resource reuse ID in this embodiment starts from 0. Therefore, in this embodiment, N=2.

[0242] For example, B0 corresponds to F1 because mod(0,3)+1 = 1. Similarly, B3, B6, B9 correspond to F1; B1, B4, B7, B10 correspond to F2; and B2, B5, B8, and B11 correspond to F3.

[0243] In an embodiment, the resource reuse pattern of each ID may be determined by:

[0244] mod(l,M)+1

[0245] where mod(X,Y) is a function of the modulo operation of X divided by Y, l is the ID, and M refers to the maximum number of resource reuse patterns supported.

[0246] In an embodiment, the resource reuse pattern of each ID may be determined by:

[0247]

[0248] in To obtain the function (eg, underlying function) of the largest integer less than or equal to X, l is the ID, and N refers to the maximum index number of the resource reuse pattern.

[0249] In an embodiment, the resource reuse pattern of each ID may be determined by:

[0250]

[0251] in is a function that obtains the largest integer less than or equal to X, l is the ID, and M refers to the maximum number of resource reuse patterns supported.

[0252] In an embodiment, the resource reuse pattern indicates only one of the frequency region and the polarization pattern. In this embodiment, the ID is determined by considering only one factor.

[0253] In an embodiment, the resource reuse pattern of each RS configuration is indicated by a QCL relationship. In this embodiment, the resource reuse pattern of each RS is implicitly indicated by the configured QCL relationship. In this embodiment, it is assumed that the RS used for measurement shares the same properties as the associated reference signal used for QCL indication, such as frequency region, polarization mode.

[0254] In an embodiment, the reference signal REF-A is configured with a QCL relationship including the reference signal REF-X as a reference for QCL-Type-D and / or Type-D. That is, the reference signals REF-A and REF-X share the same resource reuse pattern.

[0255] In an embodiment, the definition of QCL type is defined as:

[0256] - 'QCL-TypeA': {Doppler shift, Doppler spread, average delay, delay spread}

[0257] - 'QCL-TypeB': {Doppler shift, Doppler spread}

[0258] - 'QCL-TypeC': {Doppler shift, average delay}

[0259] - 'QCL-TypeD': {spatial Rx parameters}

[0260] In an embodiment, RSs configured within the same resource set (e.g., resource group) may have at least one of the following restrictions:

[0261] a) Assume that the port numbers of the RSs are the same;

[0262] b) Assume that the RSs have the same time domain behavior (e.g., periodic, semi-persistent, or aperiodic);

[0263] c) When the RS is a periodic or semi-persistent RS, the RS has the same periodicity;

[0264] d) When the RS is a non-periodic RS, the transmission of the RS is triggered by a single signaling;

[0265] e) RSs mapped to the same resource group may be allocated to adjacent symbols (or time slots), and gaps (eg, time gaps and / or frequency gaps) may be allocated between RSs having different resource reuse patterns.

[0266] In an embodiment, the time gap may be determined taking into account the UE capability and the time unit may be specified as a symbol or a time slot. If the RSs are in different resource reuse patterns, there is a requirement for the timing duration of RF tuning or "synchronization". If RSs across different resources are transmitted in consecutive symbols without time gaps, inaccurate measurements may be obtained.

[0267] In an embodiment, the time gap is specified as a minimum value.

[0268] In an embodiment supporting a UE that simultaneously receives RSs through different resource reuse patterns, a time gap may not be required (eg, the time gap is set to 0).

[0269] In an embodiment, the UE is not scheduled during the measurement period, where switching across resources is involved (eg, during a time gap). That is, the UE is not expected to receive any scheduled channels / RS in the frequency region.

[0270] Figure 6 FIG. 2 shows a schematic diagram of RS resource allocation according to an embodiment of the present invention. Figure 6 In FIG, three RSs (RS1, RS2, and RS3) are transmitted in adjacent symbols, where RS1 corresponds to polarization mode P0 and frequency region F1, RS2 corresponds to polarization mode P1 and frequency region F1, and RS3 corresponds to polarization mode P0 and frequency region F0. Since RS1 and RS2 have different resources (i.e., polarization modes P0 and P1), the time gap TG1 is maintained between RS1 and RS2. Similarly, the time gap TG2 is maintained between RS2 and RS3. Note that TG1 is smaller than TG2 because RS1 and RS2 differ only in polarization mode, while RS2 and RS3 differ in both polarization mode and frequency region.

[0271] In an embodiment, the time gap may be set to 0 for certain resource switching between RSs transmitted in adjacent symbols.

[0272] Case-2: In this case, up to K resource sets (e.g., resource groups) are configured to the UE in a single or multiple resource settings, where K is a positive integer. In an embodiment, each resource set has its own resources (e.g., resource reuse pattern) for measurement. For example, the resource reuse pattern can be configured for each resource set (e.g., each resource group).

[0273] In an embodiment, the configuration transmitted from the BS explicitly indicates the resource reuse pattern for each resource set.

[0274] In an embodiment, each RS set is transmitted in its own frequency region. In this case, the index of the corresponding frequency region is configured for each RS set.

[0275] In an embodiment, each RS set uses its own polarization mode for transmission. In this embodiment, a corresponding polarization mode is configured for each RS set.

[0276] In an embodiment, each RS set uses its own polarization mode and frequency region for transmission. In this embodiment, the resource reuse pattern can be defined as a parameter including both the polarization mode and the frequency region, and the resource reuse pattern is configured for each RS set. Alternatively or additionally, the corresponding index of the frequency region and the polarization mode is configured for each RS set.

[0277] In an embodiment, the BS may configure an ID for each RS set, wherein each ID is associated with a specific resource reuse pattern. Figure 4 and 5 And the corresponding description will not be described here for the sake of brevity.

[0278] In an embodiment, the RS configuration may have at least one of the following restrictions:

[0279] a) Assume that the port number of all RSs is the same;

[0280] b) Assume that all RSs have the same time domain behavior (e.g., periodic, semi-persistent, or aperiodic);

[0281] c) When the RS is a periodic or semi-persistent RS, all RSs have the same periodicity;

[0282] d) When the RS is a non-periodic RS, the transmission of the RS is triggered by a single signaling;

[0283] e) RSs in the same resource set may be allocated into adjacent symbols (or time slots), and gaps (eg, time gaps and / or frequency gaps) may be allocated between RSs in different resource sets (eg, resource sets having different resource reuse patterns).

[0284] In an embodiment, the time gap may be determined taking into account the UE capability and the time unit may be specified as a symbol or a time slot. In the case of RSs in different resource reuse patterns, time gaps may be inserted for timing durations used for RF tuning or "synchronization". If RSs across different resources are transmitted in consecutive symbols without time gaps, inaccurate measurements may be obtained.

[0285] In an embodiment, the time gap is specified as a minimum value.

[0286] In an embodiment, the time gap may be zero.

[0287] In embodiments supporting UEs that simultaneously receive RSs through different resource reuse patterns, time gaps may not be required (eg, the time gaps are set to 0).

[0288] In an embodiment, the UE is not scheduled during the measurement period, where switching across resources is involved (eg, during a time gap). That is, the UE is not expected to receive any scheduled channels / RS in the frequency region.

[0289] Case-3: In this case, up to K resource sets are configured to the UE in multiple resource settings. In this embodiment, the resource reuse pattern may be configured for each resource setting (ie, each resource set).

[0290] In an embodiment, in each resource setting, the same frequency region is shared by RSs within a resource set included in the resource setting.

[0291] In an embodiment, in each resource setting, the same polarization pattern is shared by RSs within a resource set included in the resource setting.

[0292] Example 2: One or more conditions that trigger measurement and reporting

[0293] Based on the configuration received from the BS, the UE may perform measurement and transmit at least one report with the measurement result to the BS.

[0294] Case-0:

[0295] In an embodiment, the measurement / reporting is triggered by the BS.

[0296] Case-1:

[0297] In an embodiment, the UE triggers measurement / reporting when at least one of the following criteria is met:

[0298] a) The elevation angle between the UE and the BS exceeds the angle threshold,

[0299] b) The distance between the UE and a reference point (e.g., a reference point for a serving resource / beam) exceeds a range threshold or is not a minimum value (e.g., compared to the distance between the UE and reference points for other sources / beams).

[0300] c) the timer duration configured for the wireless network expires, or

[0301] d) RSRP / RSRQ / SINR (eg, the measured value corresponds to the serving resource / beam) exceeds a range threshold or is not maximum (eg, compared to the measured values ​​of other sources / beams).

[0302] In an embodiment, serving resources / beams refer to resources where data (eg, PDSCH), configuration, and scheduling information are transmitted.

[0303] In an embodiment, measurement / reporting is triggered by the UE when the criteria of distance and RSRP / RSRQ / SINR are met.

[0304] In an embodiment, measurement / reporting is triggered by the UE when the criteria of elevation angle and RSRP / RSRQ / SINR are met.

[0305] In an embodiment, the criteria for triggering measurement / reporting may be configured by the BS.

[0306] In an embodiment, criteria such as defined as triggering conditions for measurement / reporting may be configured to align with the reporting configuration of each UE.

[0307] Case-2:

[0308] In an embodiment where the reference signal for measurement is configured by multiple resource sets (e.g., as proposed in Case 2 in Embodiment 1), the UE follows the order of resource set IDs for measurement. In multiple resource settings, the measurement follows the order of resource setting IDs and then the order of resource set IDs. As an example, it can be emphasized that such group-level indication occurs once the same resource reuse pattern is shared between resources within each group.

[0309] Example 3: Resources for carrying reports

[0310] Case-0:

[0311] In an embodiment, the report may include at least one of reference signal received power (RSRP), layer 1 signal to interference plus noise ratio (L1-SINR), reference signal received quality (RSRQ), deviation of RSRP, deviation of L1-SINR deviation of RSRQ, resource index, resource set index or ID.

[0312] In an embodiment, the ID may refer to the ID of the corresponding RS.

[0313] In an embodiment, the ID may refer to the ID of the RS having the best reception quality (eg, the highest L1-SINR, the best RSRQ and / or the maximum RSRP).

[0314] In an embodiment, the ID represents a frequency reuse pattern associated with the corresponding RS.

[0315] Case-1:

[0316] In this case, the measurement / reporting is triggered by the BS and the report may be carried by a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) according to scheduling from the BS.

[0317] In an embodiment, the transmission time of the scheduled resources carrying the report is Z time units after the corresponding measurement. Because the uplink (UL) resources including the polarization pattern used for the report may be different from the resources allocated for the measurement (e.g., the last RS during a measurement). Therefore, after the measurement is completed, the RF module of the UE should have enough time to tune to the UL resources for report transmission.

[0318] In an embodiment, the quantity Z may be determined by considering at least one of the following:

[0319] a) the amount of resources used for measurement;

[0320] b) Resource switching gaps (such as the above-mentioned time gaps);

[0321] c) Duplex mode;

[0322] d) Timing advance.

[0323] In an embodiment, the number of resources for measurement indicates how many RSs are to be measured and the corresponding configuration, such as bandwidth.

[0324] In an embodiment, a resource switching gap may refer to a gap for switching between resources for measurement (requiring more resources and switching, more time before reporting).

[0325] In an embodiment, the resource switching gap may refer to a gap between a measurement resource and a report resource: if the measurement resource is different from the report resource, a switch needs to be performed after the measurement.

[0326] In an embodiment, the duplex mode refers to frequency division duplex FDD and / or time division duplex (TDD). In an embodiment, the duplex mode may also refer to full duplex mode, half duplex mode and / or the following two half duplex modes:

[0327] Category A half-duplex FDD operation: The guard period is created by the UE in the following way:

[0328] The last part of the downlink subframe immediately preceding the uplink subframe is not received from the same UE.

[0329] Class B half-duplex FDD operation: Guard period, each guard period refers to a half-duplex protection subframe, which is created by the UE in the following way:

[0330] a downlink subframe immediately preceding an uplink subframe is not received from the same UE, and

[0331] A downlink subframe immediately following an uplink subframe is not received from the same UE.

[0332] In an embodiment, the timing advance (TA) refers to the TA adjustment for UL transmission. That is, the offset between the scheduled reception and the reported UL transmission may be greater than the value of TA. In addition, measurements within the TA adjustment region for UL transmission may not be performed.

[0333] Case-2:

[0334] In case-2, once a predefined rule is met (e.g., case 2 of embodiment 2), the UE triggers measurement / reporting. In this case, the measurement report can be carried by pre-configured resources. For example, the pre-configured resources can be configured to grant PUSCH through radio resource control (RRC), which is periodic and has a certain periodicity.

[0335] It should be noted that the measurement results are carried only on the configured resources that meet the timing constraints highlighted in Case-1.

[0336] Case-3:

[0337] In case-3, once the predefined rules are met, the UE triggers measurement / reporting. In an embodiment, there are no available resources for carrying the corresponding measurement results. In this case, the UE can send a scheduling request and / or a buffer status report to the BS.

[0338] In an embodiment, before reporting the measurement results (after sending the SR / BSR), the UE does not perform any measurements.

[0339] Embodiment 4: Actions taken by the BS after receiving the report

[0340] Case-1: The BS sends signaling to the UE to instruct the switching of service resources.

[0341] In an embodiment, the signaling is performed at the UE group level. For example, J (positive integer) components are included in the signaling, each component including at least one of the following:

[0342] a) Target resource ID for switching service resources;

[0343] b) Resource reuse pattern for switching service resources;

[0344] c) ID used to switch service resources;

[0345] b) the reference point of the group; or

[0346] c) Elevation angle threshold for grouping.

[0347] Specifically, when the BS groups the UEs and configures corresponding grouping information for the UEs, only the target resource ID for handover service resources is sufficient.

[0348] In an embodiment, the signaling including the J components may be RRC signaling, a medium access control element (MACCE), or DCI.

[0349] In an embodiment, the service resource may refer to frequency resources, time domain resources, etc., which carry corresponding data / control / RS transmitted from the BS to the UE.

[0350] In an embodiment, the BS sends DCI to the UE to indicate the service resources. In this embodiment, the target resource ID (eg, frequency resource ID such as BWP ID or CC ID), resource reuse pattern (eg, only polarization pattern ID) are included in the DCI.

[0351] In an embodiment, a resource reuse pattern may not be transmitted to indicate switching of serving resources, for example, when the serving resources and the target resources apply the same resource reuse pattern and / or when the BS schedules resources with the same attributes for a certain UE only based on reported UE capabilities.

[0352] Note that the definition of resource reuse mode in Embodiment 4 is the same as that in Embodiment 1, and will not be described here for the sake of brevity.

[0353] In an embodiment, the UE selects a corresponding target resource ID corresponding to the grouping criteria (ie, a reference point for grouping and / or an elevation angle threshold for grouping).

[0354] In an embodiment, the UE decodes the signaling of switching serving resources and starts monitoring the physical downlink control channel (PDCCH) and / or RS in the target resource after K time units.

[0355] In an embodiment, the UE fails to decode the signaling of the switching service resource. In this embodiment, the UE may send feedback to inform the BS, which may be a scheduling request or a physical random access channel (PRACH).
