Description
Technical Field
The present application relates to wireless communications, and more particularly to measuring weight factors (measurement weight factor).
Background
Measurement is a key function in wireless communication systems that supports mobility and efficient operation. There are currently various measurements such as intra-frequency (intra-frequency) and inter-frequency (inter-frequency) layer 3 (L3) measurements in the same radio access technology (radio access technology, RAT), intra-frequency and inter-frequency layer 1 (layer 1, L1) measurements in the same RAT, L3 inter-frequency measurements in other RATs, non-terrestrial network (non-terrestrial network, NTN) frequency measurements, positioning measurements, received signal strength indication (received signal strength indicator, RSSI)/channel occupancy (channel occupation, CO) measurements. With the rapid development of mobile communication systems, user Equipment (UE) needs to measure more and more frequencies for more and more use cases. Due to UE implementation limitations, UEs typically make inter-frequency measurements in the gap (gap). In some cases, it may even be necessary to perform co-channel measurements in the gap. With the need for more frequency measurements, the measurement delay on each frequency will become longer and longer, or more independent gaps will be required, resulting in more interruptions of the serving cell.
Considering the purpose of each measurement, some require the UE to make measurements more timely, such as L1 measurements for beam management; some may not require frequent measurements by the UE, such as measurements for network optimization only. In a New Radio (NR) network, co-frequency measurements can also be performed within the gap. A measurement gap sharing scheme (measgapmering scheme) is defined to divide the measurement opportunities for common and different frequencies in gap opportunities (occasin). However, all inter-frequency measurements are treated equally. When there are multiple different frequency measurements, the measurement delay may be long, and especially the frequency range 2 (fr 2) needs to be scanned by a beam. The L1 measurement cannot accept delay.
Improvements and enhancements are needed to increase measurement efficiency and speed up measurement of some frequency layers.

Detailed Description
Reference will now be made in detail to some embodiments of the present application, examples of which are illustrated in the accompanying drawings.
Several aspects of the telecommunications system will now be described with reference to various apparatus and methods, which are described in the following detailed description, and which are illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc., collectively referred to as "elements". These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
Fig. 1 is a system diagram of an exemplary wireless network supporting measurement weight factors in accordance with an embodiment of the present application. The present application provides methods, apparatus, processing systems, and computer readable media for NR (or 5G) access technology or other radio access technology. The NR may support various wireless communication services. These services may have different quality of service (quality of service, qoS) requirements, such as latency requirements, connection density and reliability requirements, etc. The wireless communication network 100 includes one or more fixed infrastructure elements that form a network that is distributed over a geographic area. The infrastructure element may also be referred to as an access point, an access terminal, a base station, a node B, an evolved node B (eNode-B), a next generation node B (gNB), or other terminology used in the art. A base station may serve multiple mobile stations within a service area (e.g., a cell or a sector of a cell), e.g., a cell or a sector of a cell. In some systems, one or more base stations are coupled to a controller to form an access network coupled to one or more core networks. The gnbs 106, 107, and 108 are base stations in a wireless network, and their service areas may or may not overlap with each other. In an embodiment, the UE or mobile station 101 is located in a service area covered by the gnbs 106 and 107. As an example, the UE or mobile station 101 is located only in the service area of the gNB 106 and is connected with the gNB 106. The UE or mobile station 102 is located only in the service area of the gNB 107 and is connected to the gNB 107. gNB 106 is connected to gNB 107 through Xn interface 121. gNB 106 is connected to gNB 108 through Xn interface 122. 5G network entity 109 is connected to gnbs 106, 107, and 108 through NG connections 131, 132, and 133, respectively.
Fig. 1 further shows a simplified block schematic diagram of a base station and mobile device/UE supporting measurement of weight factors. The gNB 106 has an antenna 156 that transmits and receives radio signals. RF transceiver circuitry 153 coupled to the antenna receives RF signals from antenna 156, converts the RF signals to baseband signals, and sends the baseband signals to processor 152. The RF transceiver 153 also converts baseband signals received from the processor 152 into RF signals and sends to the antenna 156. The processor 152 processes the received baseband signals and invokes different functional modules to perform the functional features in the gNB 106. Memory 151 stores program instructions and data 154 to control the operation of the gNB 106. The gNB 106 also includes a set of control modules 155 for performing functional tasks to communicate with the mobile station. Wherein the control module may be implemented in circuitry, software, firmware, or a combination of the above.
In one example, a measurement weight factor is used to measure each inter-frequency object (MO) within the gap. The inter-frequency MO may be an L3 measurement on the inter-frequency layer, an L1 measurement on the inter-frequency layer, or an L1 measurement on an inter-frequency neighboring cell. The L3 measurement includes at least one of the following: l3 reference signal received power (reference signal received power, RSRP), L3 reference signal received quality (reference signal received quality, RSRQ), and L3 signal to interference and noise ratio (signal to noise and interference ratio, SINR). The L1 measurement includes L1 RSRP and/or L1 SINR. In an embodiment, the BS configures different or the same measurement weight factors for different MOs. The BS may configure one or more measurement weight factors for the same MO and configure the usage conditions of each measurement weight factor. In another embodiment, the UE performs the measurement based on the configured measurement object and the corresponding measurement weight factor. Assume that the configuration is: the frequency layer f1 has a measurement weight factor w1, the frequency layer f2 has a measurement weight factor w2 …, and the frequency layer fN has a measurement weight factor wN. The larger the measurement weight factor, the more frequently the UE measures the corresponding measurement object. At the gap opportunity t1, the frequency layers f1, f2, f4, f5 are measured, wherein the corresponding measurement weight factors are w1, w2, w4, w5. The four frequencies are measured by w 1/(w1+w2+w4+w5), w 2/(w1+w2+w4+w5), w 4/(w1+w2+w4+w5), and w 5/(w1+w2+w4+w5). The Scaling Factor (SF) required to scale the measurement delay is the reciprocal of the MO minimum measurement opportunity. In some embodiments, the SF may be a carrier-specific scaling factor (CSSF).
Fig. 1 also shows a simplified block schematic of a UE (e.g., UE 101). The UE has an antenna 165 for transmitting and receiving radio signals. An RF transceiver circuit 163 coupled to the antenna receives RF signals from the antenna 165, converts the RF signals to baseband signals, and sends the baseband signals to the processor 162. In one embodiment, the RF transceiver may include two RF modules (not shown) for transmission and reception of different frequency bands. The RF transceiver 163 also converts the baseband signal received from the processor 162 into an RF signal and transmits to the antenna 165. The processor 162 processes the received baseband signals and invokes different functional modules to perform the functional features in the UE 101. The memory 161 stores program instructions and data 164 to control the operation of the UE 101. The antenna 165 sends uplink transmissions to the antenna 156 of the gNB 106 and receives downlink transmissions from the antenna 156 of the gNB 106.
The UE 101 also includes a set of control modules for performing functional tasks. These control modules may be implemented in circuitry, software, firmware, or a combination of the above. Configuration receiver 191 receives one or more measurement configurations from a network entity in the wireless network, wherein the one or more measurement configurations configure a plurality of MOs to be measured in one or more configured measurement gaps, each MO corresponding to a frequency layer or a cell on a frequency layer, each frequency layer being associated with one or more MOs. The weight factor module 192 obtains a measurement weight factor for each MO, where one or more measurement configurations include a set of measurement weight factors. The measurement module 193 applies the respective measurement weight factors for each MO to perform inter-frequency measurements within the configured measurement gap opportunities. In some embodiments, the UE 101 further includes a measurement controller 194 for obtaining a measurement opportunity for each frequency layer or measurement object based on the set of measurement weight factors. In one embodiment, the measurement controller 194 further obtains a scaling factor for the frequency layer or measurement object based on the respective measurement opportunity for the frequency layer or measurement object in each gap opportunity.
Fig. 2 is a schematic diagram of an exemplary NR wireless system with a centralized upper layer of NR radio interface stacks according to an embodiment of the present application. Different protocol split options are possible between Central Units (CUs) and Distributed Units (DUs) of the gNB node. The functional partitioning between CUs and DUs of the gNB node may depend on the transport layer. The low performance transmission between the CUs and DUs of the gNB node may enable the higher protocol layers of the NR radio stack to be supported in the CUs, since the higher protocol layers have lower performance requirements on the transport layers in terms of bandwidth, delay, synchronization and jitter. In one embodiment, the service data adaptation protocol (service data adaptation protocol, SDAP) and packet data convergence protocol (packet data convergence protocol, PDCP) layers are located at the CU, while the radio link control (radio link control, RLC), medium access control (medium access control, MAC) and Physical (PHY) layers are located at the DU. The core unit (core unit) 201 is connected to a central unit 211 having a gNB upper layer 252. In an embodiment 250, the gNB upper layer 252 includes a PDCP layer and an optional SDAP layer. The central unit 211 is connected to distributed units 221, 222, and 223, wherein the distributed units 221, 222, and 223 correspond to cells 231, 232, and 233, respectively. Distributed units 221, 222, and 223 include a gNB lower layer 251. In an embodiment, the gNB lower layer 251 includes PHY, MAC, and RLC layers. In another embodiment 260, each gNB has a protocol stack 261 including SDAP, PDCP, RLC, MAC and a PHY layer.
Fig. 3 is an exemplary schematic diagram of a measurement configuration with measurement weight factors according to an embodiment of the application. In one example, the measurement weight factor is used for inter-frequency measurements. Measurement configuration 300 includes measurement gap configuration 310, measurement object configuration 320, and measurement weight factor configuration 330. Each measurement gap configuration includes a measurement gap repetition period (measurement gap repetition period, MGRP) and an offset (offset). The UE can learn when to have gap opportunities by measuring the gap configuration. As shown by measurement gap 311, mgrp=20 ms, with 8 gap opportunities, such as gap opportunities 1-8, within 160 ms. Each configured gap may be associated with one or more MOs, one or more MOs may be measured in each measurement gap. For example, gap timing 1 has mo_1, mo_2, and mo_3, and gap timing 2 has mo_1 and mo_4. The measurement configuration also includes one or more measurement objects, such as mo_1 321, mo_2 322, mo_3 323, and mo_4 324. Each MO is associated with a frequency layer or a cell on a frequency layer. For example, mo_1 measurement is used for L1 measurement on inter-frequency f1, and mo_4 is used for L1 measurement on inter-frequency f 2. Each frequency layer may be associated with a plurality of MOs, such as mo_1 configured for L1 f1 measurement and mo_3 configured for L3 f1 measurement. In one example, a set of measurement weight factors 330 may be configured. In an embodiment, the set of measurement weight factors may be configured for each frequency layer. In another embodiment, the set of measurement weight factors may be configured for each MO. In one embodiment, different measurement weight factors may be configured for the same MO under different conditions.
Fig. 4A is an exemplary diagram of acquiring measurement opportunities for each MO based on measurement weight factors according to an embodiment of the present application. The measurement gap 400 is configured with a plurality of gap opportunities. Multiple MOs may be configured, such as 5 different frequency MOs configured to measure in the gap, including L3 measurements on f 1-f 4 and L1 measurements on f 2. Specifically, mo_1 401 is for inter-frequency L3 measurement on f1, mo_2 402 is for inter-frequency L3 measurement on f2, mo_3 403 is for inter-frequency L1 measurement on f2, mo_4 404 is for inter-frequency L3 measurement on f3, and mo_5405 is for inter-frequency L3 measurement on f 4. In the gap timing #1, a total of 4 different frequency MOs can be measured: mo_1 401, mo_2 402, mo_3 403, and mo_4 404. In gap timing #2, 3 different frequency MOs may be measured: mo_1 401, mo_3 403, and mo_5405. In gap timing #3, 3 different frequency MOs can be measured: mo_1 401, mo_3 403, and mo_4 404. In gap timing #4, 3 different frequency MOs may be measured: mo_1 401, mo_3 403, and mo_5405.
No weighting factor is configured in configuration 410, corresponding to all measurement weighting factors being equal to 1. The number of observed/possible MOs in gap timings #1, #5, and #9 is 4, and 3 in gap timings #2- #4, #6- #8, and #10- # 12. Accordingly, for gap opportunities #1, #5, and #9, the measurement opportunity for each MO in the respective gap opportunity is 1/4; for gap opportunities #2- #4, #6- #8, and #10- #12, the measurement opportunities were 1/3. The SF of each MO is acquired based on the measurement opportunity. SF is the reciprocal of the MO minimum measurement opportunity. Accordingly, the SF for each MO in configuration 410 is as follows:
| MO numbering | MO (description) | SF |
| MO_1 | L3 f1 | 4 |
| MO_2 | L3 f2 | 4 |
| MO_3 | L1 f2 | 4 |
| MO_4 | L3 f3 | 4 |
| MO_5 | L3 f4 | 3 |
In one example, a network entity (e.g., a base station) configures different measurement weight factors for different measurement objects. The UE may be configured with different types of measurement gaps. The measurement weight factor is applicable to, but not limited to, measurement gaps by UE, measurement gaps by frequency range, small gaps controlled by the network. Let f1 have w1, f2 have w2 …, fN have wN, where fi is the frequency layer corresponding to one or more MOs and wi is the measurement weight factor. fi and fj may be two frequency layers in the same frequency associated with different MOs. Wi may be configured for each frequency layer or for each MO. When wi and fi are configured for each MOWhen a plurality of MOs are used, the maximum wi is selected. The UE performs measurements based on the configured measurement objects and the corresponding measurement weight factors. The larger the measurement weight factor, the more frequently the UE measures the corresponding measurement object. The measurement opportunities for the frequency layers in each gap opportunity are calculated as follows: at the gap timing t1, it is assumed that the measurement opportunities for the frequencies f1, f2, f4, f5,4 are p 1,t1 ＝w1/(w1+w2+w4+w5)，p 2,t1 ＝w2/(w1+w2+w4+w5)，p 4,t1 ＝w4/(w1+w2+w4+w5)，p 5,t1 =w5/(w1+w2+w4+w5). For fi, SF is { 1} pi,t1 ,1/ pi,t2 ,1/ pi,t3 ,…,1/ pi,tK Maximum value of }, where K is the number of gap opportunities within 160 ms. SF is a factor that scales the delay requirement of the measurement.
In configuration 420, a measurement weight factor {1,1,5,1,1} is configured for each MO of MO_1 through MO_5, respectively. Mo_1, mo_2, mo_4 and mo_5 are configured with measurement weight factor '1', mo_3 is configured with measurement weight factor '5'. After application of the configured measurement weight factors, the number of observed/possible equivalent MOs in the gap occasions #1, #5 and #9 is 8, and 7 in the gap occasions #2- #4, #6- #8 and #10- # 12. Accordingly, the measurement opportunities for mo_1, mo_2, mo_4 at gap timings #1, #5, and #9 are 1/8, the measurement opportunities for mo_3 at gap timings #1, #5, and #9 are 5/8, the measurement opportunities for mo_1, mo_4 at gap timings #3, and #11 are 1/7, the measurement opportunities for mo_1, mo_5 at gap timings #2, #4, #6, #8, #10, and #12 are 1/7, and the measurement opportunities for mo_3 at gap timings #2- #4, #6- #8, and #10- #12 are 5/7. For convenience, fig. 4A shows simplified measurement opportunities for each MO, but some MOs may not be measured in some gap opportunities. For example, in gap timing #2, mo_2 and mo_4 do not measure. The SF of each MO is acquired based on the measurement opportunity. SF is the reciprocal of the MO minimum measurement opportunity. Accordingly, the SF for each MO in configuration 420 is as follows:
| MO numbering | MO (description) | SF |
| MO_1 | L3 f1 | 8 |
| MO_2 | L3 f2 | 8 |
| MO_3 | L1 f2 | 8/5 |
| MO_4 | L3 f3 | 8 |
| MO_5 | L3 f4 | 7 |
Fig. 4B is an exemplary diagram of acquiring measurement opportunities for each MO based on measurement weight factors, wherein different cells apply different measurement weights, according to an embodiment of the present application. In one embodiment, an MO is configured for/corresponds to a frequency layer. In one embodiment, an MO is configured for/corresponds to a cell of a frequency layer. For example, different MOs may be used for the same measurements for different cells. The measurement is performed in the gap if 5 different frequency MOs are configured, including L3 measurement on f 1-f 4 and L1 measurement on f 2. Specifically, mo_1 435 is used for inter-frequency L3 measurement on f1, mo_2 436 is used for inter-frequency L1 measurement of cell 1 on f2, mo_3 437 is used for inter-frequency L1 measurement of cell 2 on f2, mo_4 438 is used for inter-frequency L3 measurement on f3, and mo_5 439 is used for inter-frequency L3 measurement on f 4. Mo_2 436 and mo_3 437 are both L1 measurements on f2, where mo_2 436 is used for cell 1 and mo_3 437 is used for cell 2. Different MOs may be used for the same measurements for different cells. In an embodiment, different cells of the same measurement may employ different measurement weights, such as mo_2 436 for cell 1 and mo_3 437 for cell 2 may be different.
In configuration 430, a measurement weight factor {1,1,5,1,1} is configured for each MO of MO_1 through MO_5, respectively. Mo_1, mo_2, mo_4 and mo_5 are configured with measurement weight factor '1', mo_3 is configured with measurement weight factor '5'. After application of the configured measurement weight factors, the number of observed/possible equivalent MOs in the gap occasions #1, #5 and #9 is 8, and 7 in the gap occasions #2- #4, #6- #8 and #10- # 12. Accordingly, the measurement opportunities for mo_1, mo_2, mo_4 at gap timings #1, #5, and #9 are 1/8, the measurement opportunities for mo_3 at gap timings #1, #5, and #9 are 5/8, the measurement opportunities for mo_1, mo_4 at gap timings #3, and #11 are 1/7, the measurement opportunities for mo_1, mo_5 at gap timings #2, #4, #6, #8, #10, and #12 are 1/7, and the measurement opportunities for mo_3 at gap timings #2- #4, #6- #8, and #10- #12 are 5/7. For convenience, fig. 4B shows simplified measurement opportunities for each MO, but some MOs may not be measured in some gap opportunities. For example, in gap timing #2, mo_2 and mo_4 do not measure. The SF of each MO is acquired based on the measurement opportunity. SF is the reciprocal of the MO minimum measurement opportunity. Accordingly, the SF for each MO in configuration 430 is as follows:
fig. 4C is an exemplary diagram of acquiring measurement opportunities for each MO based on measurement weight factors, wherein different MOs perform combined measurements at different layers, according to an embodiment of the present application. In some embodiments, one or more different MOs may be combined. For example, 5 different frequency MOs may be configured to make measurements in the gap, including L3 measurements on f 1-f 4 and L1 measurements on f 2. Specifically, mo_1 445 is used for inter-frequency L3 measurement on f1, mo_2 446 is used for inter-frequency L3 measurement on f2, mo_3 447 is used for inter-frequency L1 measurement on f2, mo_4 448 is used for inter-frequency L3 measurement on f3, and mo_5 449 is used for inter-frequency L3 measurement on f 4. In configuration 440, a measurement weight factor {1,1,5,1,1} is configured for each MO of MO_1 through MO_5, respectively. Mo_1, mo_2, mo_4 and mo_5 are configured with measurement weight factor '1', mo_3 is configured with measurement weight factor '5'. In one embodiment, measurements on the same frequency for different layers may be combined, such as the L3 measurement of MO_2 446 and the L1 measurement of MO_447 may be combined. In one embodiment, when one or more MOs merge, the largest weight factor is applied to all the merged MOs. In another embodiment, the smallest weight factor is applied to all merged MOs. In another embodiment, the weighting factors of the merge MOs may be preconfigured or dynamically configured. In an embodiment, the weighting factors for one or more merged MOs may be determined based on one or more merge rules. In exemplary embodiment 441, mo_2 446 and mo_447 are combined and a measurement weight factor '5' is applied to mo_2 446 and mo_447.
After application of the configured measurement weight factors, the number of observed/possible equivalent MOs in the gap timings #1, #5, and #9 is 7, and 7 in the gap timings #2- #4, #6- #8, and #10- # 12. Accordingly, the measurement opportunities for mo_1, mo_4 at gap timings #1, #5, and #9 are 1/7, the measurement opportunities for mo_2, mo_3 at gap timings #1, #5, and #9 are 5/7, the measurement opportunities for mo_1, mo_3 at gap timings #3, and #11 are 1/7, the measurement opportunities for mo_1, mo_5 at gap timings #2, #4, #6, #8, #10, and #12 are 1/7, and the measurement opportunities for mo_3 at gap timings #2- #4, #6- #8, and #10- #12 are 5/7. For convenience, fig. 4C shows simplified measurement opportunities for each MO, but some MOs may not be measured in some gap opportunities. For example, in gap timing #2, mo_2 and mo_4 do not measure. The SF of each MO is acquired based on the measurement opportunity. SF is the reciprocal of the MO minimum measurement opportunity. Accordingly, the SF for each MO in configuration 440 is as follows:
| MO numbering | MO (description) | SF |
| MO_1 | L3 f1 | 7 |
| MO_2 | L3 f2 | 7/5 |
| MO_3 | L1 f2 | 7/5 |
| MO_4 | L3 f3 | 7 |
| MO_5 | L3 f4 | 7 |
Fig. 5 is an exemplary schematic diagram of measurement weight factor configuration and measurement opportunity and SF determination in accordance with an embodiment of the application. In one example, the measurement weight factor 520 is configured. MO is associated with a frequency layer 512 and a measurement type 511, such as L1 measurement or L3 measurement. The measurement weight factors 520 may be configured per MO or per frequency layer. In one embodiment, the BS configures one or more weight factors 521 for the same MO (e.g., MO 510) and configures a usage condition for each weight factor. The condition may be that no neighbor cells with some frequencies or some RATs are detected and/or that the quality of the serving cell and/or the detectable cells of some frequencies or some RATs or some MOs is below/above a threshold, wherein the thresholds of different cells or frequencies or RATs or MOs may be different. In some embodiments, the weight factor condition 530 includes that no neighbor cells with one or more frequency layers are detected, and/or that no neighbor cells with one or more RATs are detected, and/or that the quality of the serving cell is below a predefined threshold, and/or that the quality of the serving cell is above a predefined threshold, and/or that the quality of a detectable cell with one or more frequency layers is above a predefined threshold, and/or that the quality of a detectable cell with one or more RATs is above a predefined threshold. For example, the weighting factor of the LTE MO may be configured to be 1/3 provided that the RSRP of at least one detected NR cell (including the serving cell) is greater than-100 dBm. When the condition is met, the LTE MO adopts a weight factor of 1/3, otherwise, adopts a default factor of 1. In an embodiment 550, the UE obtains a measurement opportunity for each frequency layer based on the set of measurement weight factors. In an embodiment 570, the SF of the frequency layer is obtained based on the respective measurement opportunity of the frequency layer in each gap opportunity.

In step 601, the ue receives one or more measurement configurations from a network entity in a wireless network, wherein the one or more measurement configurations configure a plurality of MOs to be measured in one or more configured measurement gaps, each MO corresponding to a frequency layer or a cell of a frequency layer, each frequency layer being associated with one or more MOs. In step 602, the ue obtains a measurement weight factor for each MO, where one or more measurement configurations include a set of measurement weight factors. In step 603, the ue applies the respective measurement weight factor for each MO, performing inter-frequency measurements within the configured measurement gap.

In step 701, a base station configures one or more measurement configurations for a user equipment in a wireless network, wherein the one or more measurement configurations configure a plurality of MOs to be measured in one or more configured measurement gaps, each MO corresponding to a frequency layer or a cell of a frequency layer, each frequency layer being associated with one or more MOs. In step 702, the base station configures a measurement weight factor for each MO, wherein one or more measurement configurations include a set of measurement weight factors. In step 703, the base station transmits one or more measurement configurations to the UE.
