Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to a Chinese patent application filed in China on August 6, 2020, bearing application number 202010785151.8 and entitled "Reference signal measurement method, terminal and network side equipment," the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of communications, and more particularly to a reference signal measurement method, a terminal, and a network side device. [Background technology]

[0003] Conventional Layer 1 (L1) measurement techniques mainly measure the reference signal (RS) of the own cell and have a series of measurement limitations. Measurement of neighboring cell RSs can only be performed at Layer 3 and is limited to the measurement time configuration. For example, when the neighboring cell RS is a synchronization signal and physical broadcast signal (SSB), measurement of the SSB is limited to the SSB measurement time configuration (SS / PBCH Block Measurement Time Configuration, SMTC). As can be seen from the above, the lack of measurement limitations when performing L1 measurements on neighboring cell RSs in related technologies prevents UEs from efficiently performing Layer 1 measurements on neighboring cell RSs, which is disadvantageous for mobility management such as cell switching. Summary of the Invention [Problem to be solved by the invention]

[0018] FIG. 1 shows a block diagram of a wireless communication system applicable to an embodiment of the present application. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be referred to as a terminal device or user equipment (UE), and may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a personal digital assistant, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device, a vehicle-mounted equipment (VUE), a pedestrian-mounted equipment (PUE), etc., and wearable devices include a bracelet, earphones, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited to the embodiment of the present application.

As long as the same technical effect can be achieved, the base station is not limited to a specific technical term. In the embodiments of the present application, only a base station in an NR system is taken as an example, but it should be noted that the specific type of the base station is not limited.

[0019] This application refers to the FR1 frequency band and the FR2 frequency band. The FR1 frequency band is in the frequency range of 450 MHz-6 GHz, also known as the sub-6 GHz frequency band, and the FR2 frequency band is in the frequency range of 24.25 GHz-52.6 GHz, commonly referred to as millimeter wave (mmWave). FR2 in this application not only refers to the narrowly defined 24.25 GHz-52.6 GHz frequency range, but also to other possible frequency ranges higher than FR1. For example, FR2 in this application may also refer to FR3, FR4, and higher frequency bands.

[0020] Hereinafter, the reference signal measurement method, terminal, and network side device provided in the embodiments of the present application will be described in detail with reference to the drawings according to specific embodiments and their application scenarios.

[0021] 2, an embodiment of the present application provides a reference signal measurement method 200, which can be performed by a terminal. In other words, the method can be performed by software or hardware installed in the terminal, and includes the following steps S202 and S204.

[0022] In S202, the terminal performs layer L1 measurement on reference signals of neighboring cells / neighboring transmission and reception points (TRPs) according to measurement restriction conditions, and obtains measurement results.

[0023] In S204, the terminal transmits the measurement result.

[0024] Optionally, the measurement restriction conditions relate to at least one of the following: whether a reference signal in the own cell / own TRP and a reference signal of an adjacent cell / adjacent TRP collide; the frequency band position of the reference signal, e.g., FR1, FR2; whether the reference signal in the own cell / own TRP and the reference signal of an adjacent cell / adjacent TRP have the same or different subcarrier spacing (SubCarrier Spacing, SCS); and the use of the reference signal.

[0025] In this embodiment, the terminal can perform L1 measurements on reference signals of neighboring cells according to measurement restriction conditions, and can also perform L1 measurements on reference signals of neighboring TRPs according to measurement restriction conditions.

[0026] The neighboring TRPs mentioned in the examples of this application may be TRPs in neighboring cells in the case of inter-cell multi-TRP (inter-cell MTRP) or neighboring TRPs in the own cell in the case of intra-cell multi-TRP (intra-cell MTRP).

[0027] It should be noted that the neighboring cells may also be neighboring transmission and reception points (TRPs), in other words, the neighboring cells include neighboring TRPs. Among them, the serving cell and the neighboring cells may be distinguished by identifier information such as a physical cell identifier (PCI), a resource pool index (CORESET Pool Index), a transmission and reception identifier (TRP ID), or other types of cell identifiers.

[0028] The reference signals of the neighboring cells / neighboring TRPs include at least one of a synchronization and physical broadcast signal (SSB), a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), a phase tracking reference signal (PTRS), and a tracking reference signal (TRS).

[0029] In the embodiment of the present application, the terminal can perform layer L1 measurement on the reference signals of neighboring cells / neighboring TRPs according to the measurement restriction conditions, obtain the measurement results, and transmit the measurement results to the network side device. This solves the problem that the related art lacks measurement restrictions when performing L1 measurement on neighboring cell reference signals, so that the terminal cannot efficiently perform layer 1 measurement on neighboring cell reference signals, which is disadvantageous to mobility management, and contributes to matching interference between cells / TRPs, improving system capacity, and improving user experience.

[0030] Optionally, if the reference signal is an SSB, the network side device may further configure the SSB period and position within the cluster (ssb-PositionsInBurst), so that the terminal can estimate all SSB positions and periods of the neighboring cell / neighboring TRP. Wherein, ssb-PositionsInBurst is the position of the SSB within the cluster. Generally, a base station periodically transmits SSB clusters, and one SSB cluster includes multiple SSBs. The position of the SSB within the cluster is the order in which the SSB is located among these SSBs. For example, before S202, the terminal may receive configuration information from the network side device, which indicates the SSB period, position within the cluster, etc. of the neighboring cell / neighboring TRP.

[0031] In one example, in this embodiment, the SSB period and position within the cluster, etc. may be configured in the serving cell configuration (ServingCellConfig), serving cell common configuration (ServingCellConfigCommon), or serving cell common configuration system information block (ServingCellConfigCommonSIB) of the own cell or neighboring cells.

[0032] After configuring the SSB period and position within the cluster according to the own cell, the network side device may further configure identifier information of neighboring cells / neighboring TRPs, such as a physical cell identifier (PCI) and a control resource set resource pool index (CORESETPoolIndex), where the CORESETPoolIndex may be a TRP identifier, a TRP ID, or other types of cell identifiers.

[0033] In one example, the measurement behavior introduced in S202 is performed within the measurement time configuration, that is, the measurement restriction condition in this example may be that the terminal performs layer L1 measurement on the reference signals of neighboring cells / neighboring TRPs within the measurement time configuration and obtains the measurement results.

[0034] In this example, for example, if the reference signal is an SSB of a neighboring cell / TRP, the terminal performs layer L1 measurement on the SSB of the neighboring cell / TRP within an SSB measurement time configuration (SS / PBCH Block Measurement Time Configuration, SMTC) to obtain a measurement result. For example, if the reference signal is a CSI-RS of a neighboring cell / TRP, the terminal performs layer L1 measurement on the CSI-RS of the neighboring cell / TRP within a CSI-RS measurement time configuration (CSI-RS Measurement Time Configuration, CMTC) to obtain a measurement result. Optionally, the CSI-RS is a CSI-RS for mobility. For example, if the reference signal is an SRS of a neighboring cell / TRP, the terminal performs layer L1 measurement on the SRS of the neighboring cell / TRP within an SRS measurement time configuration (SRS Measurement Time Configuration) to obtain a measurement result. In the following, all references to SSB and measurement time arrangement can be extended to CSI-RS and CSI-RS measurement time arrangement and SRS and SRS measurement time arrangement, and will not be repeated.

[0035] Of course, the measurement time arrangement of the CSI-RS and SRS may be determined based on the SMTC, or based on the measurement time arrangement of other reference signals. The measurement time arrangement determined based on the SMTC may be determined by directly using the SMTC as the measurement time arrangement, or by using the linear processing result of the SMTC as the measurement time arrangement, such as a*SMTC+b, where a is a decimal number and b is a decimal number or an integer. Optionally, a=1; b may be negative or positive.

[0036] In one example, the measurement behavior introduced in S202 may be without any restriction on measurement time allocation. For example, if the reference signal is an SSB of a neighboring cell / neighboring TRP, the terminal may perform layer L1 measurements on the SSB of the neighboring cell / neighboring TRP without any restriction on measurement time allocation. In this example, "without any restriction on measurement time allocation" may be understood as an exception to the measurement restriction condition. Similar behavior exists for the CSI-RS and SRS of the neighboring cell / neighboring TRP.

[0037] The measurement behaviors introduced in the above two examples can be realized by configuration by the network side equipment and further by the terminal capabilities. For example, the network side equipment configures the terminal to perform layer L1 measurements on the reference signals of neighboring cells / neighboring TRPs within the measurement time configuration and obtain measurement results. Furthermore, for example, if the terminal capabilities are strong and meet certain capability conditions, the terminal can perform layer L1 measurements on the reference signals of neighboring cells / neighboring TRPs without measurement time configuration restrictions and obtain measurement results.

[0038] The reference signals of neighboring cells / neighboring TRPs described in each embodiment of this specification may satisfy at least one of the following items 1), 2), 3), and 4).

[0039] 1) Cell identifier information of neighboring cells / neighboring TRPs is configured in the configuration information of the terminal reference signal. For example, cell identifier information of neighboring cells / neighboring TRPs is configured / activated / updated in the configuration information of the terminal reference signal.

[0040] In this example, when cell identifier information of a neighboring cell / neighboring TRP is configured in the reference signal configuration information, the terminal determines that the reference signal is a reference signal of a cell of the neighboring cell / neighboring TRP.

[0041] 2) Reference signals related to neighboring cells / neighboring TRPs in the Transmission Configuration Indicator (TCI) / spatial related information / quasi-co-location (QCL) information related to the terminal's reference signal configuration.

[0042] Optionally, the reference signal related to the neighboring cell / neighboring TRP in the TCI described in this example may be specifically the reference signal in the QCL information included in the TCI belonging to the neighboring cell / neighboring TRP. For example, the configuration information of the reference signal in the QCL information included in the TCI includes the identifier information of the neighboring cell / neighboring TRP.

[0043] Optionally, the reference signals related to neighboring cells / neighboring TRPs in the spatial related information described in this example may specifically be such that the reference signals included in the spatial related information belong to neighboring cells / neighboring TRPs. For example, the configuration information of the reference signals included in the spatial related information includes the identifier information of the neighboring cells / neighboring TRPs.

[0044] Optionally, the reference signal related to the neighboring cell / neighboring TRP in the QCL information described in this example may be specifically such that the reference signal included in the QCL information belongs to the neighboring cell / neighboring TRP. For example, the configuration information of the reference signal included in the QCL information includes the identifier information of the neighboring cell / neighboring TRP.

[0045] 3) Reference signals related to neighboring cells / neighboring TRPs in downlink control information (DCI) / control resource set (CORESET) / TCI of control channels / spatial related information / QCL information that schedule the above reference signals.

[0046] For example, the DCI / CORESET / control channel that schedules the above reference signal has TCI / spatial related information / QCL information, and the reference signal placement information included in the TCI / spatial related information / QCL information includes identifier information of adjacent cells / adjacent TRPs.

[0047] 4) The DCI / CORESET / control channel that schedules the reference signal belongs to a neighboring cell / neighboring TRP. For example, the configuration information of the DCI / CORESET / control channel that schedules the reference signal includes identifier information of the neighboring cell / neighboring TRP.

[0048] The Layer 1 (L1) beam measurements referred to in each embodiment of this specification include at least one of Layer 1 Reference Signal Received Power (RSRP) measurements, Layer 1 Signal-to-noise and Interference Ratio (SINR) measurements, Layer 1 Reference Signal Received Quality (RSRQ) measurements, beam failure measurements for beam failure recovery, and candidate beam measurements for beam failure recovery.

[0049] In order to explain in detail the measurement limiting conditions mentioned in the above-mentioned embodiments, the meanings of some of the terms will first be clarified below.

[0050] With regard to the first cell and the second cell, at least one of the first cell and the second cell is the adjacent cell / adjacent TRP introduced in the above-mentioned embodiment, and the "cell" in the first cell and the second cell may be understood to include the cell / TRP.

[0051] Optionally, the first cell and the second cell satisfy one of the following 1), 2), 3) and 4).

[0052] 1) The first cell is the current cell or the current TRP, and the second cell is the neighboring cell or the neighboring TRP. For example, the first cell is the current cell and the second cell is the neighboring cell, or for example, the first cell is the current TRP and the second cell is the neighboring TRP, or for example, the first cell is the current cell and the second cell is the neighboring TRP, or for example, the first cell is the current TRP and the second cell is the neighboring cell.

[0053] 2) The first cell is a neighboring cell or a neighboring TRP, and the second cell is the current cell or the current TRP. For example, the first cell is a neighboring cell and the second cell is the current cell, or for example, the first cell is a neighboring TRP and the second cell is the current TRP, or for example, the first cell is a neighboring cell and the second cell is the current TRP, or for example, the first cell is a neighboring TRP and the second cell is the current cell.

[0054] 3) The first cell is a neighboring cell or a neighboring TRP, and the second cell is the neighboring cell or a neighboring TRP. For example, the first cell is a neighboring cell, and the second cell is also the neighboring cell, or for example, the first cell is a neighboring TRP, and the second cell is also the neighboring TRP, or for example, the first cell is a neighboring cell, and the second cell is a neighboring TRP, or for example, the first cell is a neighboring TRP, and the second cell is a neighboring cell.

[0055] 4) The first cell is a neighboring cell or a neighboring TRP, and the second cell is another neighboring cell or a neighboring TRP. For example, the first cell is a neighboring cell and the second cell is another neighboring cell, or for example, the first cell is a neighboring TRP and the second cell is another neighboring TRP, or for example, the first cell is a neighboring cell and the second cell is a neighboring TRP, or for example, the first cell is a neighboring TRP and the second cell is a neighboring cell.

[0056] Regarding the collision between the signal of the first cell and the signal of the second cell, if the signal of the first cell and the signal of the second cell occupy the same time domain unit (e.g., symbol, OFDM symbol, data symbol, etc.), it can be called a collision, where the signal of the first cell includes one of SSB, CSI-RS, SRS, TRS, and PTRS, and the signal of the second cell includes one of SSB, CSI-RS, SRS, TRS, and PTRS.

[0057] In this way, before S202, the terminal can further determine whether the signal of the first cell and the signal of the second cell collide, and if the signal of the first cell and the signal of the second cell are within the same time domain unit, it determines that the signal of the first cell and the signal of the second cell collide.

[0058] Alternatively, whether the signal of the first cell and the signal of the second cell have collided refers to whether the OFDM symbols actually located in the signal of the first cell and the signal of the second cell have collided after taking into account the timing information of the two cells.

[0059] For example, if the timing of the second cell is slower than that of the first cell, when the signals of the two cells collide, from the perspective of the timing of the first cell, the collided OFDM symbols include the current OFDM symbol and the K OFDM symbols that follow. Optionally, K=1, or K is determined by the timing, or K is configured by the network, reported by the UE, or defaulted by the protocol.

[0060] Furthermore, if the timing of the second cell is faster than that of the own cell, when the signals of the two cells collide, from the perspective of the timing of the first cell, the collided OFDM symbols include the current OFDM symbol and the L OFDM symbols before it. Optionally, L=1, or L is determined by the timing, or L is configured by the network, reported by the UE, or defaulted by the protocol.

[0061] Of course, the above situation can also be seen from the timing of the second cell, and will not be repeated here.

[0062] Furthermore, for example, when the timing difference between two cells is smaller than a certain threshold, the collided OFDM symbols include only the current OFDM symbol. The threshold may be a default value set by a protocol, configured by the network, or determined by terminal capabilities. For example, different terminal capabilities can handle different timing differences, and the terminal may report the capabilities to the network.

[0063] Optionally, whether the signal of the first cell and the signal of the second cell collide may be determined based on whether the signal of the second cell is in a restricted section, which may be determined by at least one of the following items 1), 2), 3), and 4): 1) The restricted interval is determined by the symbol in which the first cell RS is located. 2) The restricted interval is determined by the symbol in which the first cell RS is located and K symbols preceding that symbol, where K is a positive integer. 3) The restricted interval is determined by the symbol in which the first cell RS is located and L symbols following that symbol, where L is a positive integer. 4) The restricted interval is determined by the symbol in which the first cell RS is located, K symbols before that symbol, and L symbols after that symbol.

[0064] When the subcarrier spacings SCS of the first cell and the second cell are different, the restricted interval satisfies one of the following conditions: the restricted interval is calculated by the symbols of the first cell, or the restricted interval is calculated by the symbols of the second cell, where the restricted interval is determined according to the timing of the two cells.

[0065] Whether or not the signals of the first cell and the second cell collide as described above includes at least one of the following items 1), 2), 3), and 4). 1) Whether or not a collision occurred when the downlink DL network side device transmitted. 2) Whether or not a collision occurred when the downlink DL terminal received the signal. 3) Whether or not a collision occurred when the uplink UL network side device received the signal (mainly an uplink reference signal such as SRS). 4) Whether or not a collision occurred when an uplink UL terminal transmitted (mainly an uplink reference signal such as SRS).

[0066] After defining the first cell and the second cell and interpreting the collision of the signal of the first cell and the signal of the second cell, the following will explain in detail the measurement restriction conditions introduced in each of the above-mentioned embodiments, divided into several embodiments.

[0067] Example 1 The measurement restriction condition includes performing at least one of the following items 1 and 2 when the SSB of the first cell and the SSB / CSI-RS of the second cell collide. 1. In the FR1 frequency band, the terminal measures the SSB of the first cell without any restrictions, or in the FR1 frequency band, the terminal measures one of the SSB of the first cell and the SSB / CSI-RS of the second cell, and optionally, a longer measurement period is desired for the SSB of the first cell (used for L1 beam measurement). 2. In the FR2 frequency band, the terminal measures one of the SSB of the first cell and the SSB / CSI-RS of the second cell. Optionally, a longer measurement period is desired for the SSB of the first cell (used for L1 beam measurement).

[0068] In this embodiment, "without any limiting conditions" may be understood as a special case of the measurement limiting conditions.

[0076] At least one of the first cell and the second cell is the neighboring cell / neighboring TRP.
