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, with application number 202010785151.8 and invention title "Reference Signal Measurement Method, Terminal and Network - Side Device", and all contents of this application are incorporated herein by reference.

[0002] This application belongs to the technical field of communications, and specifically relates to a reference signal measurement method, a terminal, and a network - side device.

Background Art

[0003] In conventional layer 1 (L1) measurement technologies, mainly the reference signal (RS) of the serving cell is measured, and there are a series of measurement limitations. The measurement of the RS of adjacent cells can only be performed at layer 3 and is restricted within the measurement time allocation. For example, when the RS of an adjacent cell is a synchronization signal and physical broadcast channel block (SSB), the measurement of the SSB is restricted within the SSB measurement time configuration (SMTC). As can be seen from the above, due to the lack of measurement limitations when performing L1 measurement on the RS of adjacent cells in related technologies, the terminal cannot efficiently perform layer 1 measurement on the RS of adjacent cells, which is disadvantageous for mobility management.

[0015] In the following, while referring to the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Naturally, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

Also, in the specification and claims, "and / or" indicates at least one of the connected objects, and the symbol " / " generally indicates that the related objects before and after are in an "or" relationship.

[0017] It should be noted that the technology described in the embodiments according to the present application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems. Furthermore, for example, it can also be used in other wireless communication systems such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments according to the present application can generally be used interchangeably. The described technology can be used in the above-mentioned systems and radio communication technologies, or in other systems and radio communication technologies. However, for the purpose of illustration, the New Radio (NR) system is described in the following description, and the NR term is used in most of the following descriptions. These technologies are applicable beyond the NR system. For example, they are also applicable to the 6th Generation (6G) communication system. th Generation, 6G) communication system.

[0018] FIG. 1 shows a block diagram of a wireless communication system applicable to an embodiment according to the present application. The wireless communication system includes a terminal 11 and a network-side device 12. Here, the terminal 11 may also be referred to as a terminal device or a user equipment (UE), and may be a mobile phone, a tablet personal computer, a laptop computer also called a notebook personal computer, a personal digital assistant (PDA), a personal digital assistant, a mobile information terminal, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device, or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc. The wearable device includes a bracelet, earphones, glasses, etc. It is necessary to explain that the specific type of the terminal 11 is not limited in the embodiment according to the present application. The network-side device 12 may be a base station or a core network. Among them, the base station may be a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a next-generation Node B (gNB), a home Node B, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (TRP), or other appropriate terms in the field. If the same technical effect can be achieved, the base station is not limited to a specific technical term. In the embodiment according to the present application, only the base station in the NR system is taken as an example, but it is necessary to explain that the specific type of the base station is not limited.

[0019] In this application, the FR1 frequency band and the FR2 frequency band are mentioned. The FR1 frequency band has a frequency range of 450 MHz - 6 GHz and is also called the sub 6 GHz frequency band. The FR2 frequency band has a frequency range of 24.25 GHz - 52.6 GHz and is usually called millimeter wave (mmWave). In this application, FR2 refers not only to the narrow frequency range of 24.25 GHz - 52.6 GHz, but also to other possible higher frequency ranges than FR1. For example, in this application, FR2 may further refer to FR3, FR4, and higher frequency bands.

[0020] In the following, with reference to the drawings, a reference signal measurement method, a terminal, and a network-side device provided by the embodiments of this application will be described in detail by means of specific embodiments and their usage scenarios.

[0021] As shown in Figure 2, an embodiment of this application provides a reference signal measurement method 200, and this method can be executed by a terminal. In other words, this method can be executed 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 the reference signal of an adjacent cell / adjacent transmission and reception point (TRP) according to the measurement limit condition to obtain a measurement result.

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

[0024] Optionally, the above measurement limit condition is related to at least one item of whether the reference signal in the serving cell / serving TRP collides with the reference signal of the adjacent cell / adjacent TRP, for example, the frequency band position of the reference signal such as FR1 and FR2, whether the reference signal in the serving cell / serving TRP and the reference signal of the adjacent cell / adjacent TRP have the same subcarrier spacing (SCS) or different SCSs, and the use of the reference signal.

[0025] In this embodiment, the terminal can perform L1 measurement on the reference signal of an adjacent cell according to the measurement limitation condition, and can also perform L1 measurement on the reference signal of an adjacent TRP according to the measurement limitation condition.

[0026] The adjacent TRPs mentioned in each embodiment of this application may be the TRPs in the adjacent cells in the case of inter-cell multi-TRP (MTRP), or may be the adjacent TRPs in the serving cell in the case of intra-cell multi-TRP.

[0027] The adjacent cell may further be an adjacent transmission and reception point (TRP). In other words, it is necessary to explain that the adjacent cell includes an adjacent TRP. Among them, the serving cell and the adjacent cell may be distinguished by identifier information such as a physical cell identifier (PCI), a resource pool indicator (CORESET Pool Index), a transmission and reception identifier (TRP ID), and other types of cell identifiers.

[0028] The reference signal of the above adjacent cell / adjacent TRP includes at least one of a synchronization signal and a 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 embodiments of the present application, the terminal can perform layer L1 measurement on the reference signal of the neighboring cell / neighboring TRP according to the measurement limitation conditions to obtain a measurement result, and transmit the measurement result to the network-side device. In the related art, since there is a lack of measurement limitations when performing L1 measurement on the neighboring cell reference signal, the terminal cannot efficiently perform layer 1 measurement on the neighboring cell reference signal, and the problem of being disadvantageous for mobility management is solved, which contributes to the interference coordination between cells / TRPs, the improvement of system capacity, and the improvement of user experience.

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

[0031] In one example, in this embodiment, the period of the SSB, the position in 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 cell.

[0032] If the self-cell arranges the period of the above SSB and the position within the cluster, etc., the network-side device may further arrange the identifier information of the adjacent cell / adjacent TRP, for example, the Physical Cell Identifier (PCI), the control resource set resource pool index (CORESETPoolIndex), and the CORESETPoolIndex may be the TRP identifier, the TRP ID, or other types of cell identifiers, etc.

[0033] In one example, the measurement behavior introduced in S202 is performed within the measurement time arrangement. That is, the measurement restriction condition in this example may be that the terminal performs layer L1 measurement on the reference signal of the adjacent cell / adjacent TRP within the measurement time arrangement and obtains the measurement result.

[0034] In this example, for example, when the above reference signal is the SSB of the adjacent cell / adjacent TRP, the terminal performs layer L1 measurement on the SSB of the adjacent cell / adjacent TRP within the SSB measurement time arrangement (SS / PBCH Block Measurement Time Configuration, SMTC) and obtains the measurement result. Further, for example, when the above reference signal is the CSI-RS of the adjacent cell / adjacent TRP, the terminal performs layer L1 measurement on the CSI-RS of the adjacent cell / adjacent TRP within the CSI-RS measurement time arrangement (CSI-RS Measurement Time Configuration, CMTC) and obtains the measurement result. Optionally, the CSI-RS is the CSI-RS for mobility. Further, for example, when the above reference signal is the SRS of the adjacent cell / adjacent TRP, the terminal performs layer L1 measurement on the SRS of the adjacent cell / adjacent TRP within the SRS measurement time arrangement (SRS Measurement Time Configuration) and obtains the measurement result. All references to SSB and measurement time arrangement in the following content can be extended to CSI-RS and CSI-RS measurement time arrangement and SRS and SRS measurement time arrangement, and will not be described repeatedly.

[0035] Of course, CSI-RS and SRS may determine the measurement time arrangement based on SMTC, or may be based on the measurement time arrangements of other reference signals. Determining the measurement time arrangement based on the above SMTC may be directly using SMTC as the measurement time arrangement, or may be using the linear processing result of SMTC as the measurement time arrangement. For example, a*SMTC + b can be cited, 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 not have restrictions on the measurement time arrangement. For example, when the above reference signal is the SSB of an adjacent cell / adjacent TRP, the terminal may perform layer L1 measurement on the SSB of the adjacent cell / adjacent TRP without restrictions on the measurement time arrangement. The "without restrictions on the measurement time arrangement" in this example may be understood as a special case of the measurement restriction conditions. Similar behaviors also exist for the CSI-RS and SRS of adjacent cells / adjacent TRPs.

[0037] The measurement behaviors introduced in the above two examples can be realized by the network-side device, and can also be realized by the terminal capabilities. For example, the network-side device arranges for the terminal to perform layer L1 measurement on the reference signal of the adjacent cell / adjacent TRP within the measurement time arrangement to obtain the measurement result. Further, for example, if the terminal capabilities are strong and certain capability conditions are met, the terminal can perform layer L1 measurement on the reference signal of the adjacent cell / adjacent TRP without restrictions on the measurement time arrangement and obtain the measurement result.

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

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

[0040] In this example, when cell identifier information of an adjacent cell / adjacent TRP is arranged in the reference signal arrangement information, the terminal determines that the reference signal is the reference signal of the cell of the adjacent cell / adjacent TRP.

[0041] 2) Reference signals related to an adjacent cell / adjacent TRP in the Transmission Configuration Indicator (TCI) / spatial related information / Quasi-Co-Location (QCL) information related to the reference signal arrangement of the terminal.

[0042] Optionally, the reference signal related to the adjacent cell / adjacent TRP in the TCI described in this example may specifically be such that the reference signal included in the QCL information included in the TCI belongs to the adjacent cell / adjacent TRP. For example, the arrangement information of the reference signal included in the QCL information included in the TCI includes identifier information of the adjacent cell / adjacent TRP.

[0043] Optionally, the reference signal related to the adjacent cell / adjacent TRP in the spatial related information described in this example may specifically be such that the reference signal included in the spatial related information belongs to the adjacent cell / adjacent TRP. For example, the arrangement information of the reference signal included in the spatial related information includes identifier information of the adjacent cell / adjacent TRP.

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

[0045] 3) The reference signal related to an adjacent cell / adjacent TRP in the downlink control information (DCI) / control resource set (CORESET) / TCI of the control channel / spatial correlation information / QCL information that schedules the above reference signal.

[0046] For example, the DCI / CORESET / control channel that schedules the above reference signal has TCI / spatial correlation information / QCL information, and the arrangement information of the reference signal included in the TCI / spatial correlation information / QCL information includes the identifier information of the adjacent cell / adjacent TRP.

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

[0048] The layer 1 (L1) beam measurement mentioned in each embodiment of this specification includes at least one of layer 1 reference signal received power (RSRP) measurement, signal-to-noise and interference ratio (SINR) measurement of layer 1, reference signal received quality (RSRQ) measurement of layer 1, beam failure measurement for beam failure recovery, and candidate beam measurement for beam failure recovery.

[0049] To explain the measurement limit conditions mentioned in each of the above embodiments in detail, first, the meanings of some of the terms will be clarified below.

[0050] Regarding 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 embodiments, and the "cell" in the first cell and the second cell may be understood to include a 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 an adjacent cell or an adjacent TRP. For example, the first cell is the current cell and the second cell is an adjacent cell. Further, for example, the first cell is the current TRP and the second cell is an adjacent TRP. Further, for example, the first cell is the current cell and the second cell is an adjacent TRP. Further, for example, the first cell is the current TRP and the second cell is an adjacent cell.

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

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

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

[0056] Regarding the collision between the signal of the first cell and the signal of the second cell, if the signals of the first cell and the second cell occupy the same time domain unit (for example, symbol, OFDM symbol, data symbol, etc.), it may be called a collision. Among them, 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 signals of the first cell and the second cell collide. If the signals of the first cell and the second cell are within the same time domain unit, it is determined that the signals of the first cell and the second cell collide.

[0058] Optionally, whether the signals of the first cell and the second cell collide is whether the OFDM symbols where the signals of the first cell and the second cell actually are collide after considering the timing information of the two cells.

[0059] For example, when the timing of the second cell is later than that of its own cell, when the signals of the two cells collide, from the perspective of the timing of the first cell, the colliding OFDM symbols include the current OFDM symbol and the subsequent K OFDM symbols. Optionally, K = 1, or K is determined according to the timing, or K is arranged by the network, reported by the UE, or set to the default by the protocol.

[0060] Furthermore, for example, when the timing of the second cell is earlier than that of its own cell, when the signals of the two cells collide, from the perspective of the timing of the first cell, the colliding OFDM symbols include the current OFDM symbol and the previous L OFDM symbols. Optionally, L = 1, or L is determined according to the timing, or L is arranged by the network, reported by the UE, or set to the default by the protocol.

[0061] Of course, the above situation can also be viewed from the perspective of the timing of the second cell, and it 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 symbol includes only the current OFDM symbol. The threshold may be set to the default by the protocol, may be configured by the network, or may be determined according to the terminal capabilities. For example, if the terminal capabilities are different, the timing differences that can be processed are also different, and the terminal may report the capabilities to the network.

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

[0064] When the subcarrier spacing SCS of the first cell and the second cell is different, the restricted interval satisfies either one of the following: the restricted interval is calculated by the symbol of the first cell, and the restricted interval is calculated by the symbol of the second cell. Here, the restricted interval is determined according to the timing of the two cells.

[0065] Whether the signals of the first cell and the second cell collide as described above includes at least one of the following 1), 2), 3), and 4). 1) Whether there is a collision when the downlink DL network-side device transmits. 2) Whether there is a collision when the downlink DL terminal receives. 3) Whether there is a collision when the uplink (UL) network-side device receives (mainly uplink reference signals such as SRS). 4) Whether there is a collision when the uplink (UL) terminal transmits (mainly uplink reference signals such as SRS).

[0066] After defining the first cell and the second cell and interpreting the collision between the signals of the first cell and the second cell, the following will detail the measurement limitation conditions introduced in each of the above embodiments by dividing them into several embodiments.

[0067] (Embodiment 1) The measurement limitation conditions include performing at least one of the following 1 and 2 when the SSB of the first cell collides with the SSB / CSI-RS of the second cell. 1. In the FR1 frequency band, the terminal measures the SSB of the first cell without measurement limitations. 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. Optionally, for the SSB of the first cell (used for L1 beam measurement), a longer measurement period is desired. 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, for the SSB of the first cell (used for L1 beam measurement), a longer measurement period is desired.

[0068] The "without measurement limitations" in this embodiment may be understood as a special case of the measurement limitation conditions.

[0069] In this embodiment, the SSB of the first cell is for L1 beam measurement, and the SSB / CSI-RS of the second cell may be used for at least one of radio link management (RLM), beam failure detection (BFD), candidate beam detection (CBD), and L1 beam measurement.

[0070] At least one of the first cell and the second cell in the embodiment is the adjacent cell / adjacent TRP introduced in each of the above embodiments. For example, the first cell is the adjacent cell / adjacent TRP introduced in each of the above embodiments.

[0071] Optionally, in the FR1 frequency band mentioned in 1 above, when the terminal measures the SSB of the first cell without restrictions, it is executed when at least one of the following 1), 2), and 3) is satisfied. 1) The SSB of the first cell and the SSB / CSI-RS of the second cell have the same SCS. 2) The first cell and the second cell belong to different cells, and the timing information of the first cell and the second cell satisfies a predetermined timing condition. 3) The SSB of the first cell and the SSB / CSI-RS of the second cell have different SCSs, and the terminal supports the simultaneous reception of data and SSB with different parameter sets (i.e., supports simultaneousRxDataSSB-DiffNumerology), or has a similar ability.

[0072] The fact that the timing information of the first cell and the second cell mentioned in 2) above satisfies a predetermined timing condition means, for example, that the timing difference between the two cells is smaller than a threshold or within a certain range, and the threshold / range is arranged by the network-side device, defined by the protocol, reported by the terminal, or the terminal satisfies the ability to support the reception of channels / signals with a certain timing difference, and the timing of the two cells is within the range of this ability at the current time.

[0073] Optionally, in the FR1 frequency band mentioned in 1 above, when the terminal measures one of the SSB of the first cell and the SSB / CSI-RS of the second cell, it is executed when at least one of the following 1), 2), 3), and 4) is satisfied. 1) The SSB of the first cell and the SSB / CSI-RS of the second cell have the same subcarrier spacing (SCS), the first cell and the second cell belong to different cells, and the timing information of the first cell and the second cell does not meet a predetermined timing condition. For example, the timing difference between the two cells is greater than or equal to a threshold value. 2) The SSB of the first cell and the SSB / CSI-RS of the second cell have different SCSs, the terminal supports simultaneousRxDataSSB-DiffNumerology, the first cell and the second cell belong to different cells, and the timing information of the first cell and the second cell does not meet a predetermined timing condition. 3) The SSB of the first cell and the SSB / CSI-RS of the second cell have different SCSs, and the terminal does not support simultaneousRxDataSSB-DiffNumerology. 4) The first cell and the second cell belong to different cells.

[0074] (Example 2) The above measurement limitation conditions include performing at least one of the following 1 and 2 when, in the FR1 frequency band, the CSI-RS of the first cell and the SSB of the second cell collide and the SSB of the second cell is within the activated bandwidth part (Band Width Part, BWP). 1. If the SSB of the second cell and the CSI-RS of the first cell have the same SCS, the terminal measures the CSI-RS of the first cell without limitation conditions. 2. If the SSB of the second cell and the CSI-RS of the first cell have different SCSs, the terminal measures the CSI-RS of the first cell without limitation conditions. Or, the terminal measures one of the CSI-RS of the first cell and the SSB of the second cell. Optionally, for the SSB of the first cell (used for L1 beam measurement), a longer measurement period is desired.

[0075] The CSI-RS of the first cell is for L1 beam measurement, and the SSB of the second cell is used for at least one of RLM / BFD / CBD / L1 beam measurement.

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

[0077] Optionally, the SSB of the second cell and the CSI-RS of the first cell mentioned in 1 above having the same SCS, and the terminal measuring the CSI-RS of the first cell without restrictions is executed when the first cell and the second cell belong to different cells and the timing information of the first cell and the second cell satisfies a predetermined timing condition. For specific examples, refer to the above introduction.
