Description

Method and apparatus for control channel state indication reference signal measurement

Technical Field

Various exemplary embodiments relate to methods and apparatus for controlling channel state indication reference signal (CHANNEL STATE indication REFERENCE SIGNAL, CSI-RS) measurements.

Background

The CSI-RS may be configured for a mobile device or User Equipment (UE) in connected mode, e.g., may be provided in a UE-specific configuration using radio resource control (radio resource control, RRC) signaling. For example, configuring the UE to perform CSI-RS measurements from the target cell may allow for a direct Handover (HO) from the servo beam in the servo cell to the improved beam in the target cell.

Disclosure of Invention

In a first aspect, a method is disclosed, the method comprising: receiving at least one signaling comprising at least one synchronization signal block (synchronization signal block, SSB) based threshold; receiving at least one SSB-based reference signal; and conditionally performing channel state indication reference signal (CSI-RS) measurements on at least one of the serving cell and the non-serving cell according to the at least one threshold and a received power (SS-RSRP) of the at least one SSB-based reference signal to the serving cell. For example, the method may be performed in a mobile device or UE. For example, the CSI-RS measurement may be a CSI-RS measurement for layer 3 (L3) Radio Resource Management (RRM).

In some example embodiments, the at least one threshold may include a threshold that may be used to control whether SS-RSRP is measured for a non-serving cell, and CSI-RS measurements may be performed for at least one of the serving cell and the non-serving cell if SS-RSRP for the serving cell satisfies a threshold condition associated with the threshold. For example, the threshold condition may include SS-RSRP for the serving cell being below the threshold. For example, if SS-RSRP for the serving cell is above the threshold, CSI-RS measurements may not be performed for at least one of the serving cell and the non-serving cell.

In some example embodiments, the at least one threshold may include a different threshold than another threshold that may be used to control whether to measure SS-RSRP for the non-serving cell, and CSI-RS measurements may be performed on at least one of the serving cell and the non-serving cell if the SS-RSRP for the serving cell satisfies a threshold condition associated with the threshold. For example, the threshold condition may include SS-RSRP for the serving cell being below the threshold. For example, if SS-RSRP for the serving cell is above the threshold, CSI-RS measurements may not be performed for at least one of the serving cell and the non-serving cell.

In some example embodiments, the at least one threshold may include a first threshold and a second threshold, at least one of which is different from a threshold that may be used to control whether SS-RSRP is measured for a non-serving cell, CSI-RS measurements may be performed for a serving cell if SS-RSRP for the serving cell meets a first threshold condition associated with the first threshold, and CSI-RS measurements may be performed for the non-serving cell if SS-RSRP for the serving cell meets a second threshold condition associated with the second threshold. For example, the first threshold condition may include SS-RSRP for a serving cell being below the first threshold, and the second threshold condition may include SS-RSRP for a serving cell being below the second threshold. For example, if the SS-RSRP for the serving cell is above the first threshold, CSI-RS measurements may not be performed for the serving cell, and if the SS-RSRP for the serving cell is above the second threshold, CSI-RS measurements may not be performed for the non-serving cell.

In some example embodiments, the at least one signaling may include first signaling including a first threshold and second signaling including a second threshold.

In some example embodiments, the at least one signaling may include a signaling including the at least one threshold.

In a second aspect, a method is also disclosed, the method comprising: transmitting at least one signaling comprising at least one SSB-based threshold; and transmitting at least one SSB-based reference signal, wherein the at least one threshold and a received power (SS-RSRP) of the at least one SSB-based reference signal to the serving cell may be used to conditionally perform CSI-RS measurements on at least one of the serving cell and the non-serving cell. For example, the method may be performed in an access network, e.g. in a base station. For example, the CSI-RS measurement may be a CSI-RS measurement for L3 RRM.

In some example embodiments, the at least one threshold may include a threshold that may be used to control whether SS-RSRP is measured for a non-serving cell, and the threshold may be associated with a threshold condition related to SS-RSRP for a serving cell and used to perform CSI-RS measurements for at least one of the serving cell and the non-serving cell. For example, the threshold condition may include SS-RSRP for the serving cell being below the threshold. For example, if the SS-RSRP to the serving cell is above the threshold, CSI-RS measurements may not be performed for at least one of the serving cell and the non-serving cell.

In some example embodiments, the at least one threshold may include a different threshold than another threshold that may be used to control whether to measure SS-RSRP for the non-serving cell, and the threshold may be associated with a threshold condition related to SS-RSRP for the serving cell and used to perform CSI-RS measurements for at least one of the serving cell and the non-serving cell. For example, the threshold condition may include SS-RSRP for the serving cell being below the threshold. For example, if the SS-RSRP to the serving cell is above the threshold, CSI-RS measurements may not be performed for at least one of the serving cell and the non-serving cell.

In some example embodiments, the at least one threshold may include a first threshold and a second threshold, at least one of the first threshold and the second threshold being different from a threshold that may be used to control whether to measure SS-RSRP for a non-serving cell, the first threshold may be associated with a first threshold condition related to SS-RSRP for a serving cell and used to perform CSI-RS measurements for a serving cell, and the second threshold may be associated with a second threshold condition related to SS-RSRP for a serving cell and used to perform CSI-RS measurements for a non-serving cell. For example, the first threshold condition may include SS-RSRP for a serving cell being below the first threshold, and the second threshold condition may include SS-RSRP for a serving cell being below the second threshold. For example, if the SS-RSRP for the serving cell is above the first threshold, CSI-RS measurements may not be performed for the serving cell, and if the SS-RSRP for the serving cell is above the second threshold, CSI-RS measurements may not be performed for the non-serving cell.

For example, the apparatus may be at least a part of a mobile device or UE. For example, the CSI-RS measurement may be a CSI-RS measurement for L3 RRM.

Detailed Description

Configuring the UE to perform CSI-RS measurements from the target cell may allow for a direct Handover (HO) from the servo beam in the servo cell to the improved beam in the target cell, while on the other hand, overhead of downlink reference signal (REFERENCE SIGNAL, RS) signaling may also be incurred. Moreover, additional CSI-RS measurements on the serving cell and/or the non-serving cell (e.g., neighbor cells) may affect the UE, e.g., in terms of possible additional measurement time, additional RS processing and post-processing, evaluation, and possible reporting, etc., which may increase the on-time (on-time) and measurement burden of the UE, for example, and may further affect the overall UE power consumption, thereby affecting the user experience.

Fig. 1 illustrates an exemplary method 100 for controlling CSI-RS measurements, such as CSI-RS measurements for layer 3radio resource management (layer 3radio resource management,L3 RRM).

As shown in fig. 1, an exemplary method 100 may include: step 110, receiving at least one signaling comprising at least one synchronization signal block (synchronization signal block, SSB) based threshold; step 120, receiving at least one SSB-based reference signal; and step 130 of conditionally performing CSI-RS measurements on at least one of the serving cell and the non-serving cell according to the at least one threshold and a received power of at least one SSB-based reference signal (hereinafter simply referred to as "SS-RSRP") to the serving cell.

In the example method 100, CSI-RS measurements for the serving cell and/or the non-serving cell may be conditionally performed according to the received at least one SSB-based threshold and SS-RSRP for the serving cell. For example, if the SS-RSRP for the serving cell is not good enough according to the received at least one SSB-based threshold, CSI-RS measurements for the serving cell, or CSI-RS measurements for the non-serving cell, or both CSI-RS measurements for the serving cell and CSI-RS measurements for the non-serving cell may not be performed; otherwise, execution may be performed. In this way, for example, network CSI-RS transmissions may be at least reduced, and thus overall UE power consumption may be reduced.

In various embodiments, one or more SSB-based thresholds may be used in the exemplary method 100 and may be provided using one or more signaling. For example, in step 110, one signaling may be received that includes one or more SSB-based thresholds (e.g., all SSB-based thresholds), or a first signaling may be received that includes a first SSB-based threshold and a second signaling may be received that includes a second SSB-based threshold.

In various embodiments, the received power of the at least one SSB-based reference signal received in step 120 may be measured and obtained in any suitable manner and at any suitable time. For example, SS-RSRP may be measured and obtained when the at least one SSB-based reference signal is received in step 120.

In fig. 1, step 120 is illustrated after step 110. In further exemplary embodiments, step 120 may be performed prior to step 110 or may be performed in parallel with step 110.

In some example embodiments, the at least one SSB-based threshold included in the at least one signaling received in step 110 may include a threshold that may be used to control whether SS-RSRP is measured for a non-serving cell. Then, in step 130, CSI-RS measurements for at least one of the serving cell and the non-serving cell may be conditionally performed according to whether the SS-RSRP for the serving cell meets a threshold condition associated with the threshold. For example, if the SS-RSRP for the serving cell is below a threshold for controlling whether to measure the SS-RSRP for the non-serving cell, CSI-RS measurements for the serving cell, or CSI-RS measurements for the non-serving cell, or both CSI-RS measurements for the serving cell and CSI-RS measurements for the non-serving cell may be performed; otherwise, no execution may be performed.

In some example embodiments, the at least one SSB-based threshold included in the at least one signaling received in step 110 may include a different threshold than a threshold that may be used to control whether SS-RSRP is measured for a non-serving cell. Then, in step 130, CSI-RS measurements for at least one of the serving cell and the non-serving cell may be conditionally performed according to whether the SS-RSRP for the serving cell meets a threshold condition associated with the threshold. For example, if the SS-RSRP for the serving cell is below the threshold different from the threshold used to control whether the SS-RSRP is measured for the non-serving cell, CSI-RS measurements for the serving cell, or CSI-RS measurements for the non-serving cell, or both CSI-RS measurements for the serving cell and CSI-RS measurements for the non-serving cell may be performed; otherwise, no execution may be performed.

In some example embodiments, the at least one SSB-based threshold included in the at least one signaling received in step 110 may include a first threshold and a second threshold. At least one of the first threshold and the second threshold may be different from a threshold that may be used to control whether SS-RSRP is measured for a non-serving cell. Then, in step 130, CSI-RS measurements for the serving cell may be conditionally performed according to whether the SS-RSRP for the serving cell meets a first threshold condition associated with a first threshold, and CSI-RS measurements for one or more non-serving cells may be conditionally performed according to whether the SS-RSRP for the serving cell meets a second threshold condition associated with a second threshold. For example, if the SS-RSRP to the serving cell is below a first threshold, CSI-RS measurements to the serving cell may be performed, otherwise no CSI-RS measurements may be performed; CSI-RS measurements for one or more non-serving cells may be performed if SS-RSRP for the serving cell is below a second threshold, otherwise may not be performed.

For example, the example method 100 may be performed in a mobile device or UE. Accordingly, fig. 2 illustrates an example method 200 for controlling CSI-RS measurements, e.g., CSI-RS measurements for L3 RRM, e.g., the example method 200 may be performed in an access network (e.g., a base station) to transmit/provide at least one signaling including at least one SSB-based threshold in step 110 of the example method 100 and at least one SSB-based reference signal in step 120 of the example method 100.

As shown in fig. 2, an exemplary method 200 may include: step 210, transmitting at least one signaling comprising at least one SSB-based threshold; and step 220, transmitting at least one SSB-based reference signal.

The at least one signaling transmitted in step 210 may be received in step 110 of the exemplary method 100, and the at least one SSB-based threshold in the at least one signaling transmitted in step 210 may correspond to the at least one threshold used in the exemplary method 100 that has been described in some exemplary embodiments above.

Thus, corresponding to exemplary method 100, for exemplary method 200, in various exemplary embodiments, the at least one threshold may include a threshold that may be used to control whether SS-RSRP is measured for a non-serving cell, and the threshold may be associated with a threshold condition that is related to SS-RSRP for a serving cell and that is used to perform CSI-RS measurements for at least one of a serving cell and a non-serving cell (e.g., if SS-RSRP for a serving cell is below the threshold, CSI-RS measurements may be performed for at least one of a serving cell and a non-serving cell, otherwise may not be performed); or the at least one threshold may be another threshold different from a threshold that may be used to control whether SS-RSRP is measured for the non-serving cell, and the another threshold may be associated with a threshold condition that is related to SS-RSRP for the serving cell and is used to perform CSI-RS measurements for at least one of the serving cell and the non-serving cell (e.g., CSI-RS measurements may or may not be performed for at least one of the serving cell and the one or more non-serving cells if SS-RSRP for the serving cell is below the threshold); or the at least one threshold may include a first threshold and a second threshold, wherein at least one of the first threshold and the second threshold may be different from a threshold that may be used to control whether SS-RSRP is measured for a non-serving cell, the first threshold may be associated with a first threshold condition that is related to SS-RSRP for a serving cell and used to perform CSI-RS measurements for a serving cell (e.g., CSI-RS measurements may be performed for a serving cell if SS-RSRP for the serving cell is below the first threshold, otherwise may not be performed), and the second threshold may be associated with a second threshold condition that is related to SS-RSRP for a serving cell and used to perform CSI-RS measurements for one or more non-serving cells (e.g., CSI-RS measurements may be performed for a non-serving cell if SS-RSRP for the serving cell is below the second threshold, otherwise may not be performed).

Additionally, one or more signaling may be transmitted to provide one or more SSB-based thresholds corresponding to receipt of at least one signaling in step 110 of the example method 100. For example, in step 210, one signaling including one or more SSB-based thresholds (e.g., all SSB-based thresholds) may be transmitted, or a first signaling including a first SSB-based threshold and a second signaling including a second SSB-based threshold may be transmitted.

In fig. 2, step 220 is illustrated after step 210. In further exemplary embodiments, step 220 may be performed prior to step 210 or may be performed in parallel with step 210.

Fig. 3 illustrates an example execution sequence 300 between the example method 100 and the example method 200.

For example, the example execution sequence 300 may involve a UE 310 and a base station (eNB or gNB) 320 in an access network. UE 310 may perform exemplary method 100 and base station 320 may perform exemplary method 200.

As shown in fig. 3, at least one signaling 330 including at least one SSB-based threshold may be transmitted by the base station 320 in step 210 and may be received by the UE 310 in step 110. Then, at the UE 310 side, at least one SSB-based threshold may be obtained for later use in step 130. In addition, at least one SSB-based reference signal 340 may be transmitted by the base station 320 in step 220 and may be received by the UE 310 in step 120. Then, on the UE 310 side, the received power of at least one SSB-based reference signal 340, i.e. SS-RSRP to the serving cell, may be measured or obtained. Then, on the UE 310 side, step 130 of the exemplary method 100 may be performed to conditionally perform CSI-RS measurements for the serving cell and/or the non-serving cell according to the obtained at least one SSB-based threshold and the SS-RSRP measured for the serving cell.

Additional exemplary embodiments in a New Radio (NR) system are described below for at least one signaling 330 and at least one SSB-based threshold. However, it should be appreciated that the exemplary methods and features of the present disclosure may also be applied in any other suitable telecommunication system, such as a long term evolution (long term evolution, LTE) system or other current or future mobile telecommunication systems.

In an embodiment, as shown in fig. 4, the at least one signaling 330 may include an s-MeasureConfig information element (information element, IE) 410.s-MeasureConfig IE, 410 may include two options, ssb-RSRP corresponding to SS-RSRP and CSI-RSRP corresponding to reference signal received power (REFERENCE SIGNAL RECEIVING poser, RSRP) of CSI-RS, where the threshold indicated by s-MeasureConfig IE410 enabling option ssb-RSRP may be used to control when UE 310 measures SS-RSRP for non-serving cells.

In an NR system, s-MeasureConfig IE410 may be used to provide a threshold that is used by the UE 310 to control when RSRP measurements are performed on non-serving cells. For example, when the received power of the reference signal 340 to the serving cell is below a threshold indicated by s-MeasureConfig IE410 of the enable option ssb-RSRP.

In this embodiment, s-MeasureConfig IE is reused 410. For example, the at least one SSB-based threshold in the at least one signaling 330 may include a threshold indicated by s-MeasureConfig IE 410 of the enable option SSB-RSRP. For example, if the SS-RSRP for the serving cell is below the threshold indicated by s-MeasureConfig IE of the enable option ssb-RSRP, the UE 310 may perform CSI-RS measurements for at least one of the serving cell and the non-serving cell in addition to the SS-RSRP for the non-serving cell.

In further exemplary embodiments, as shown in fig. 5, the at least one signaling 330 may also include signaling different from s-MeasureConfig IE 410, illustrated in fig. 5 as s-MeasureConfigCsi-rs IE 510. The s-MeasureConfigCsi-RS IE510 may include a threshold for the UE310 to determine whether to perform CSI-RS measurements on at least one of the serving cell and the non-serving cell. For example, the UE310 may perform CSI-RS measurements on at least one of the serving cell and the non-serving cell if the SS-RSRP for the serving cell is below a threshold included in the s-MeasureConfigCsi-RS IE510, or may not perform CSI-RS measurements on at least one of the serving cell and the non-serving cell if the SS-RSRP for the serving cell is above a threshold included in the s-MeasureConfigCsi-RS IE 510.

For example, s-MeasureConfig IE of the enabling option ssb-RSRP 410 may be used by the UE 310 to control when RSRP measurements are performed on non-serving cells, and the threshold indicated by the s-MeasureConfigCsi-RS IE510 may be used by the UE 310 to determine when CSI-RS measurements are performed on at least one of serving and non-serving cells.

For example, the threshold indicated by s-MeasureConfig IE 410 of the enable option ssb-RSRP may be used by the UE 310 to determine when to perform RSRP measurements on a non-serving cell and when to perform CSI-RS measurements on one of a serving cell and a non-serving cell, and the threshold indicated by s-MeasureConfigCsi-RS IE510 may be used by the UE 310 to determine when to perform CSI-RS measurements on the other of a serving cell and a non-serving cell.

For example, the threshold indicated by s-MeasureConfig IE of the enable option ssb-RSRP 410 may be used by the UE 310 to determine when to perform RSRP measurements on non-serving cells, the threshold indicated by s-MeasureConfigCsi-RS IE 510 may be used by the UE 310 to determine when to perform CSI-RS measurements on serving cells, and CSI-RS measurements on non-serving cells may not be controlled.

In this exemplary embodiment, a different threshold is introduced than that which can be used to control whether SS-RSRP is measured for a non-serving cell (i.e., the threshold indicated by s-MeasureConfig IE of the enabling option ssb-RSRP), so that SS-RSRP measurement for a non-serving cell and CSI-RS measurement for at least one of a serving cell and a non-serving cell can be controlled separately, whereby, for example, higher flexibility, less carryover, and simple configuration can be achieved.

It should be appreciated that the s-MeasureConfigCsi-rs IE 510 is an example and that any other suitable, new or legacy signaling may be used.

In another exemplary embodiment, as shown in fig. 6, a first threshold value (illustrated in fig. 6 as s-MeasureConfigCsiServing-rs IE 610) different from s-MeasureConfig IE 410 and a second threshold value (illustrated in fig. 6 as s-MeasureConfigCsiNonServing-rs IE 620) different from s-MeasureConfig IE 410 may also be included in at least one signaling 330. For example, the s-MeasureConfigCsiServing-RS IE 610 may include a threshold for the UE 310 to determine whether to perform CSI-RS measurements on a serving cell, and the s-MeasureConfigCsiNonServing-RS IE 620 may include a threshold for the UE 310 to determine whether to perform CSI-RS measurements on a non-serving cell.

For example, the UE 310 may perform CSI-RS measurements on the serving cell if the SS-RSRP for the serving cell is below a threshold included in the s-MeasureConfigCsiServing-RS IE 610, or may not perform CSI-RS measurements on the serving cell if the SS-RSRP for the serving cell is above a threshold included in the s-MeasureConfigCsiServing-RS IE 610.

For example, the UE 310 may perform CSI-RS measurements for non-serving cells if the SS-RSRP for the serving cell is below a threshold included in the s-MeasureConfigCsiNonServing-RS IE 620, or may not perform CSI-RS measurements for non-serving cells if the SS-RSRP for the serving cell is above a threshold included in the s-MeasureConfigCsiNonServing-RS IE 620.

In this exemplary embodiment, separate control of SS-RSRP measurement of a non-serving cell, CSI-RS measurement of a serving cell, and CSI-RS measurement of a non-serving cell can be performed, so that, for example, higher flexibility can be achieved.

It should be appreciated that the s-MeasureConfigCsiServing-rs IE 610 and the s-MeasureConfigCsiNonServing-rs IE 620 are examples, and that any other suitable, new or legacy signaling may be used.

In further exemplary embodiments, as shown in fig. 7, a modified s-MeasureConfig IE 710 may be included in the at least one signaling 330. Unlike s-MeasureConfig IE, 410, the modified s-MeasureConfig IE 710 may include both a threshold value that may be used to control whether SS-RSRP is measured for non-serving cells (i.e., the threshold value indicated by s-MeasureConfig IE of the enabling option ssb-RSRP) and at least one additional threshold value that is used to control whether CSI-RS measurements are performed for serving and/or non-serving cells.

For example, in addition to the threshold ssb-RSRP that may be used to control whether SS-RSRP is measured for a non-serving cell, the modified s-MeasureConfig IE may also include a threshold ssb-RSRP-CSI-RS that is used to control whether CSI-RS measurements are performed for both a serving cell and a non-serving cell.

For example, in addition to the threshold ssb-RSRP that may be used to control whether SS-RSRP is measured for a non-SERVING cell, the modified s-MeasureConfig IE may also include a threshold ssb-RSRP-CSI-RS-SERVING for controlling whether CSI-RS measurements are performed for a SERVING cell, but not provide any threshold for controlling whether CSI-RS measurements are performed for a non-SERVING cell; or whether to perform CSI-RS measurements on non-serving cells with a threshold that may be used to control whether to measure SS-RSRP on non-serving cells.

For example, in addition to the threshold ssb-RSRP that may be used to control whether SS-RSRP is measured for a non-serving cell, the modified s-MeasureConfig IE may also include a threshold ssb-RSRP-CSI-RS-NONSERVING that is used to control whether CSI-RS measurements are performed for a non-serving cell, but does not provide any threshold for controlling whether CSI-RS measurements are performed for a serving cell; or whether to perform CSI-RS measurements on the serving cell with a threshold that may be used to control whether to measure SS-RSRP on the non-serving cell.

For example, in addition to the threshold ssb-RSRP that may be used to control whether SS-RSRP is measured for a non-SERVING cell, the modified s-MeasureConfig IE may also include both a threshold ssb-RSRP-CSI-RS-SERVING for controlling whether CSI-RS measurements are performed for a SERVING cell and a threshold ssb-RSRP-CSI-RS-NONSERVING for controlling whether CSI-RS measurements are performed for a non-SERVING cell.

In this exemplary embodiment, a plurality of SSB-based thresholds may be provided in one signaling, so that, for example, gap-assisted SSB-based intra-frequency measurements can be avoided.

An example of using a modified s-MeasureConfig IE 710,710 is illustrated in figure 7. In further exemplary embodiments, a different IE than the modified s-MeasureConfig IE 710,710 may be utilized.

Fig. 8 illustrates an example apparatus 800 for controlling CSI-RS measurements (e.g., CSI-RS measurements for L3 RRM). For example, the example apparatus 800 may be at least a portion of the UE 310.

As shown in fig. 8, an exemplary apparatus 800 may include at least one processor 810 and at least one memory 820, the at least one memory 820 may include computer program code 830. The at least one memory 820 and the computer program code 830 may be configured to, with the at least one processor 810, cause the apparatus 800 to perform at least the above-described exemplary method 100.

In various exemplary embodiments, at least one processor 810 in exemplary apparatus 800 may include, but is not limited to, at least one hardware processor, including at least one microprocessor such as a central processing unit (central processing unit, CPU), a portion of at least one hardware processor, and any other suitable special purpose processor, such as a processor developed based on a field programmable gate array (field programmable GATE ARRAY, FPGA) and an Application SPECIFIC INTEGRATED Circuit (ASIC).
