Description

Method and device for measuring reference signal strength indication Technical field

The present invention relates to the field of communications, and in particular, to a method and a device for measuring a reference signal strength indicator.

Background technique

In a new access technology (NR) communication system, user equipment (UE) needs to support mobility procedures such as cell selection, cell reselection, and cell handover to achieve UE mobility, and mobility In the process, the UE needs to measure related parameters. For example, the UE needs to measure parameters during the mobility process including: synchronization signal-reference signal received power (synchronization signal-reference signal reception power (SS-RSRP)), synchronization signal-signal-to-interference and noise ratio synchronization-signal-interference plus noise ratio (SS-SINR), channel state information reference signal received power (channel-information-reference signal-reception power, CSI-RSRP), channel state information-signal-interference-noise ratio (channel-state-information- signal interference (plus interference) (CSI-SINR). Among them, SS-RSRQ is the signal power received by the UE from a cell's synchronization signal (SS) or physical broadcast channel-demodulation reference signal (PBCH-DMRS). The proportion of the total received power in a fixed time-frequency range, so SS-RSRQ reflects the signal quality of the cell, where the total received power is measured by the reference signal strength indicator (RSSI) How to measure RSSI in an NR communication system is currently under discussion.

Summary of the invention

The technical problem to be solved by the embodiments of the present invention is to provide a method and a device for measuring a reference signal strength indication, so as to measure RSSI on a specified time domain resource.

In a first aspect, the present application provides a method for measuring a reference signal strength indicator, including:

The terminal device receives the RSSI measurement configuration information from the network device, the subcarrier interval SCS information of the synchronization signal block SSB, and the synchronization signal measurement timing configuration (SMTC) information; the terminal device according to the timing of the first cell and the SMTC information Determine the time domain position of the SMTC window currently performing the RSSI measurement. The SMTC information is used to indicate the configuration of the SMTC window currently performing the RSSI measurement. The SMTC information may include the SMTC window period, the length of the SMTC window, and the offset of the SMTC window. The terminal device determines the symbols participating in the RSSI measurement according to the RSSI measurement configuration information and the SCS information of the SSB, the timing of the second cell, and the time domain position of the SMTC window; the symbols participating in the RSSI measurement are all covered by the SMTC window. The terminal device performs RSSI measurement on the determined symbol.

The timing reference of the SMTC window is the first cell, which indicates that the first cell is the timing reference cell of the SMTC window. The slot boundary of the SMTC window is based on the slot boundary of the first cell. The timing reference of the SMTC window is the second cell. The second cell is a timing reference cell for RSSI measurement, and the slot boundary of the RSSI measurement is based on the slot boundary of the second cell.

The SCS information of the SSB indicates the subcarrier interval used by the SSB. The subcarrier interval is used to determine the slot length of the first cell and the second cell. For example, the subcarrier interval is 30kHz and the slot length is 0.5ms.

The RSSI measurement configuration information includes measurement time slot information and end symbol information. The measurement time slot information is used to indicate the position of the time slot participating in the RSSI measurement in the SMTC window, and the end symbol information is used to indicate the positive participation in the RSSI measurement in the time slot. Position of orthogonal frequency division multiplexing (OFDM) symbols.

Wherein, a certain symbol / slot is covered by the SMTC window, which indicates that the start time of the symbol / slot is not earlier than the start time of the SMTC window, and the end time is not later than the end time of the SMTC window.

Implementing the embodiment of the present invention, when the terminal device needs to measure the RSSI of a certain cell, it considers the timing reference of the SMTC window and the timing of the RSSI measurement when determining the symbols participating in the RSSI measurement in the SMTC window, so as to accurately determine the participation in the RSSI in the SMTC window The position of the measured symbols improves the accuracy of RSSI measurements.

In a possible design, there is a timing difference between the first cell and the second cell, that is, the time slot boundaries between the first cell and the second cell are not aligned, thereby causing the boundary of the SMTC window and the The time slot boundaries of the two cells are not aligned.

In one possible design, the symbols that determine participation in RSSI measurements include:

The terminal device determines the symbols participating in the RSSI measurement in M valid time slots according to the RSSI measurement configuration information. In summary, the terminal device uses the N consecutive time slots starting from the first time slot covered by the SMTC window as the N timeslots mapped in the bitmap, thereby ensuring that each bit in the bitmap can be mapped to 1. The mapping between time slots, bitmaps, and time slots within the SMTC window is clear.

In a possible design, the RSSI measurement configuration information includes a bitmap, and the bitmap contains N bits. The N bits are used to map N consecutive time slots. The length of the SMTC window is N time slots. The last time slot of the consecutive time slots is not covered by the SMTC window, that is, the last time slot of the N consecutive time slots overlaps the SMTC window. In this application, the overlap of a certain time slot / symbol with the SMTC window indicates that the start time of the time slot / symbol is no later than the end time of the SMTC window, and the end time is no earlier than the start time of the SMTC window. In summary, when the timing reference of the SMTC window and the timing reference of the RSSI measurement are different, the first multiple bits in the bitmap are mapped to multiple time slots starting from the first time slot covered by the SMTC window. The mapping relationship between the slot information and the time slot in the SMTC window is clear, and the terminal device can accurately perform RSSI measurement on the specified time domain resource.

In a possible design, the RSSI measurement configuration information includes a bitmap, and the bitmap contains N + 1 bits. The first N bits of the N + 1 bits are used to map N consecutive time slots, that is, N + 1. The first one of the bits is discarded, and the length of the SMTC window is N + 1 time slots, and the N consecutive time slots are all covered by the SMTC window. In summary, when the timing reference of the SMTC window and the timing reference of the RSSI measurement are different, the previous multiple bits in the bitmap start with the second cell-based timing covered by the SMTC window and the first slot of the SCS-based SCS. Multiple time slots are mapped, and the mapping relationship between the measurement time slot information and the time slots in the SMTC window is clear, and the terminal device can accurately perform RSSI measurement on the specified time domain resource.

In a possible design, the RSSI measurement configuration information includes a bitmap, and the bitmap contains N + 1 bits, and the next N bits of the N + 1 bits are used to map N consecutive time slots, that is, N + The last bit of 1 bit is discarded, and the length of the SMTC window is N + 1 time slots, and the N consecutive time slots are all covered by the SMTC window. In summary, when the timing reference of the SMTC window and the timing reference of the RSSI measurement are different, the later multiple bits in the bitmap start with the second cell-based timing covered by the SMTC window and the first slot of the SCS SCS. Multiple time slots are mapped, and the mapping relationship between the measurement time slot information and the time slots in the SMTC window is clear, and the terminal device can accurately perform RSSI measurement on the specified time domain resource.

In a possible design, the RSSI measurement configuration information includes a bitmap. The bitmap contains N bits, and the N bits are used to map N consecutive time slots. The length of the SMTC window is N + 1 time slots. The N consecutive time slots are covered by the SMTC window. When the timing reference of the SMTC window and the timing reference of the RSSI measurement are different, the number of bits in the bitmap is less than the number of time slots contained in the SMTC window. The bitmap and the second cell-based timing sum covered by the SMTC window are The multiple slots starting from the first slot of the SCS of the SSB are mapped, and the mapping relationship between the measurement slot information and the slots in the SMTC window is clear, and the terminal device can accurately perform RSSI measurement on the specified time domain resource.

In one possible design, the symbols that determine participation in RSSI measurements include:

The terminal device determines M valid time slots in N consecutive time slots starting from the first time slot overlapping the SMTC window according to the RSSI measurement configuration information, the timing of the second cell, and the SCS information of the SSB. M and N are An integer greater than 1, M≤N;

The terminal device determines the symbols participating in the RSSI measurement in M valid time slots according to the RSSI measurement configuration information. In this application, the overlap of a certain time slot / symbol with the SMTC window indicates that the start time of the time slot / symbol is no later than the end time of the SMTC window, and the end time is no earlier than the start time of the SMTC window.

In a possible design, the RSSI measurement configuration information includes a bitmap, and the bitmap contains N bits. The N bits are used to map N consecutive time slots. The length of the SMTC window is N time slots. The N The first time slot of the consecutive time slots is not covered by the SMTC window, that is, the first time slot of the N consecutive time slots overlaps the SMTC window. In summary, when the timing reference of the SMTC window and the timing reference of the RSSI measurement are different, the bitmap and the overlapped SMTC window based on the second cell timing and SSB information of the first slot of the SCS start N Consecutive time slots, each bit in the bitmap can map a time slot in the SMTC window, the mapping relationship between the measured time slot information and the time slot in the SMTC window is clear, and the terminal device can accurately identify the time domain resources To perform RSSI measurements.

In a possible design, M valid time slots are indicated from N consecutive time slots by way of bitmap mapping. For example, when the bit value is 1, the time slot mapped by the bit is a valid time slot; when the bit value is 0, the time slot mapped by the bit is not a valid time slot.

In a second aspect, this application provides an RSSI measurement method, including:

The network device determines one or more of RSSI measurement configuration information, SCS information, and SMTC information of the SSB; where the bitmap included in the RSSI measurement configuration information includes N bits, N = length of the STMC window / time slot length- 1. The time slot length is related to the SCS of the SSB; the network device sends one or more of the RSSI measurement configuration information, the SCS information of the SSB, and the SMTC information to the terminal device. In summary, when the network device configures the bitmap included in the RSSI measurement configuration information, the number of bits in the bitmap is less than the number of timeslots contained in the SMTC window. When the bitmap is mapped to the timeslots in the SMTC window, It can ensure that each bit in the bitmap can be mapped to a complete time slot, thereby ensuring that the mapping relationship between the bitmap and the time slots in the SMTC window is clear.

The terminal device may also be a handheld device with wireless communication function, a vehicle-mounted device, a wearable device, a computing device, or other processing device connected to a wireless modem, and the like. Terminal equipment can be called different names in different networks, for example: terminal equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication Equipment, user agents or user devices, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital processing (PDA), Terminal equipment in 5G networks or future evolution networks.

The network device in this application can also be called a base station device, which is a device deployed in a radio access network to provide wireless communication functions, including but not limited to: a base station (for example, BTS (base transceiver station, BTS), node B (NodeB, NB), evolutionary node B (eNB or eNodeB), transmission node or transceiver point (TRP or TP) in the NR system or next-generation node B (generation nodeB, gNB) , Base stations or network equipment in future communication networks), relay stations, access points, in-vehicle devices, wearable devices, wireless-fidelity (Wi-Fi) stations, wireless backhaul nodes, small stations, micro stations and many more.

Among them, in the NR communication system, the time domain resources participating in the RSSI measurement are located in the SMTC window, and the time domain resources participating in the RSSI measurement are determined by the RSSI measurement configuration information. The RSSI measurement configuration information includes the measurement slot information (measurementSlot) and the end symbol. Information (endSymbol).

Exemplarily, the measurement time slot information is a bitmap. The bitmap contains multiple bits. Each bit maps a time slot in the SMTC window. The bit map and the time slot in the SMTC window are one by one. Mapping relationship, the length of the time slot is determined by the SCS of the SSB. Specifically, when the SSB SCS is 15 × 2 μ ^kHz, a slot length of ² -μ ms, μ is an integer greater than or equal to zero. The value of each bit is used to determine the time slot that participates in RSSI measurement in the mapped multiple time slots. This embodiment is called a valid time slot. For example: a bit value of 1 indicates that the time slot mapped by a bit is a valid time slot, which needs to participate in RSSI measurement; a bit value of 0 indicates that the time slot mapped by this bit is not a valid time slot. Gap does not need to participate in RSSI measurement.

Exemplarily, the end symbol information is used to indicate the OFDM symbols participating in the RSSI measurement in a valid time slot. The end symbol information may have multiple values, and each value represents a range of the OFDM symbols participating in the RSSI measurement in the time slot. For example: each slot contains 14 OFDM symbols, and the symbol indexes are 0 to 13 respectively; the value of the end symbol information can be 0 to 3; the value between the value of the end symbol information and the index of the OFDM symbol participating in the RSSI measurement The mapping relationship is shown in Table 1:

Table 1

Among them, how to map the measurement time slot information to the time slot in the SMTC window is related to the timing reference of the RSSI measurement. The timing reference of the RSSI measurement is determined according to the following principles:

1. For measurement at the same frequency, the timing reference for RSSI measurement is the serving cell at that frequency;

2. For the measurement of inter-frequency frequencies, the timing reference for RSSI measurement is any cell at that frequency.

Co-frequency point refers to the frequency point where the serving cell is located. In the scenarios of carrier aggregation (CA) and non-dual connectivity (DC), the serving cell refers to the primary cell that provides services to the UE ( PCell). In the CA or DC scenario, the serving cell includes a master cell, a master-slave cell (PSCell), and all slave cells (SCell). Inter-frequency points represent frequencies other than the same-frequency points.

The mapping between the measurement time slot information and the time slot in the SMTC window is not only related to the timing reference of the RSSI measurement, but also to the timing reference of the SMTC window. For example, in an NR communication system, the timing reference of the SMTC window is a special cell (SpecCell, SpCell) of NR, and SpCell refers to a primary school cell (Pcell) or a primary and secondary cell (PSCell). Therefore, in a non-standalone (NSA) scenario, the NR SpCell refers to the PSCell of the NR. In a standalone (SA) scenario, NR SpCell refers to the PCell of NR. For the same-frequency measurement at the frequency where the SCell is located and the inter-frequency measurement at the different frequency, the mapping relationship between the measurement slot information and each slot in the SMTC window may not be clear. The following describes several mapping modes of measurement time slot information and each time slot in the SMTC window during the process of intra-frequency measurement and inter-frequency measurement.

Scenario 1: For the same-frequency measurement at the frequency where the SpCell is located, the timing reference of the RSSI measurement and the timing reference of the SMTC window are both SpCell. Figure 1b is a schematic diagram of the mapping relationship between the measured time slot information and each time slot in the SMTC window during co-frequency measurement at the frequency where the SpCell is located. Assume that the length of the SMTC window is 5 ms and the synchronization signal block (SSB) The subcarrier spacing (SCS) is 30 kHz, and the length of the time slot obtained according to the SCS of the SSB is 0.5 ms. Because the timing reference of the RSSI measurement is the same as the timing reference of the SMTC window, the boundary of the SMTC window and the slot boundary of the SpCell are aligned. At this time, the measurement time slot information (bitmap) and the time slot in the SMTC window are aligned. The mapping relationship is clear, and the terminal device can accurately determine the location of the time domain resources participating in the RSSI measurement in the SMTC window according to the RSSI measurement configuration information.

Scenario 2: For the same frequency measurement at the frequency where the SCell is located, the timing reference of the SMTC window is NR SpCell (the first cell), but the timing reference of the RSSI measurement is the serving cell at the frequency point, that is, the Scell (the second cell). The timing of NR SpCell and SCell may not be the same. For example: in the intra-band noncontiguous NR CA scenario, the maximum receiving timing difference (MRTD) of each cell is 3 microseconds; in the inter-band NR CA scenario, the timing difference between cells may be Up to 33 microseconds (in the case of FR1). Therefore, the boundary of the SMTC window shown in FIG. 1c may not be aligned with the slot boundary. Assume that the length of the SMTC window is 5ms, and the SCS SCS is 30kHz. According to the SCS SCS, the time slot length is 0.5ms. At this time, the number of complete time slots based on the timing of the second cell in the SMTC window is: Length × (SSB / 15 of SSB) -1 = 9, and the length of measurement slot information (bitmap) is: Length of SMTC window × (SCS / 15 of SSB) = 10, measurement slot information (bit (Figure) The mapping relationship between the time slots in the SMTC window and the time slot in the SMTC window is not clear, which will cause the UE to be unable to accurately determine the location of the time domain resources participating in the RSSI measurement in the SMTC window.

Scenario 3: For inter-frequency measurements at non-serving frequency points, the difference between the timing reference of the RSSI measurement and the timing reference of the NR SpCell is greater than that of the same-frequency measurement. First, there is no restriction on the reception timing difference between the inter-frequency cell and the serving cell in the 3GPP protocol. Second, the timing reference cell for RSSI measurement during inter-frequency measurement can be any cell at that frequency. The UE selects the reference cell at the timing. Randomness can also lead to very large timing differences. The ambiguity of the mapping relationship between the measurement time slot information (bitmap) and the time slot in the SMTC window will cause the UE to be unable to accurately determine the location of the time domain resources participating in the RSSI measurement in the SMTC window.

According to the above analysis, it is known that the current RSSI measurement process does not consider that the timing reference of the RSSI measurement and the timing reference of the SMTC window are different. In this case, the mapping relationship between the measurement time slot information and the time slot in the SMTC window is not It is clear that the UE cannot accurately determine the location of the time domain resources participating in RSSI measurement in the SMTC window, so how to specify the mapping relationship between the measurement slot information and each time slot in the SMTC window is a problem that needs to be solved at present.

In order to solve the technical problems mentioned above, this application provides the following technical solutions:

2 is a schematic flowchart of a method for measuring a reference signal strength indication according to an embodiment of the present invention. In the embodiment of the present invention, the method includes:

S201: The network device sends RSSI measurement configuration information, SCS information and SMTC information of the SSB to the terminal device, and the terminal device receives RSSI measurement configuration information, SCS information, and SMTC information of the SSB from the network device.

Specifically, the RSSI measurement configuration information is used to indicate a time domain resource participating in the RSSI measurement within the SMTC window. In a possible implementation manner, the RSSI measurement configuration information includes measurement slot information and end symbol information. For the definition of the measurement slot information and the end symbol information, reference may be made to the description in the embodiments of FIG. 1a to FIG. 1c, and details are not described herein again. The SMTC information is used to indicate the time domain position of the SMTC window. The SMTC information includes one or more of the period of the SMTC window, the length of the SMTC window, and the offset of the SMTC window. The period of the SMTC window indicates the period in which the SMTC window appears. The length of the SMTC window represents the duration of the SMTC window, and the offset of the SMTC window represents the offset of the SMTC window from the reference time point.

In a possible implementation manner, the network device configures RSSI measurement configuration information, SSB SCS information, and SMTC information of the terminal device through radio resource control (RRC) signaling in a connected state. In yet another possible implementation manner, in an idle / inactive state, the network device may configure RSSI measurement configuration information, SSB SCS information, and SMTC information for the terminal device through system information block (SIB) information.

In a possible implementation manner, the measurement configuration information includes a bitmap, where the bitmap contains N bits, N = length of the SMTC window / time slot length-1, the time slot length is related to the SCS of the SSB, and the The length is N + 1 timeslots. The length of the SMTC window can be determined according to the SMTC information.

S202. The terminal device determines a time domain position of the SMTC window.

Specifically, the timing reference of the SMTC window is the first cell, which indicates that the first cell is a timing reference cell of the SMTC window, and the slot boundary of the SMTC window is based on the slot boundary of the first cell. The terminal device determines the time domain position of the SMTC window currently performing RSSI measurement according to the timing of the first cell and the SMTC information, and the time domain position of the SMTC window includes a start time and an end time.

S203. The terminal device determines a symbol participating in the RSSI measurement.

Specifically, the terminal device first determines a bitmap according to the measurement time slot information included in the RSSI measurement configuration information, and then determines the length of the time slot in the SMTC window according to the SCS information of the SSB, and determines the time to participate in the RSSI measurement according to the timing of the second cell. Slot boundary, and then according to the mapping relationship between the value of the bitmap and the time slot in the SMTC window, determine the time slot in the SMTC window that participates in the RSSI measurement, and then determine the participation in the time slot that participates in the RSSI measurement according to the end symbol information OFDM symbol measured by RSSI. The timing reference of the RSSI measurement is the second cell, and the timing reference of the SMTC window is the first cell. There is a timing difference between the timing of the first cell and the timing of the second cell, that is, the time slot boundaries of the first cell and the second cell are not aligned. Then the boundary of the SMTC window and the boundary of the time slot participating in the RSSI measurement are also misaligned.

The timing reference for RSSI measurement is the second cell, which indicates that the second cell is the timing reference cell for RSSI measurement, and the slot boundary of the RSSI measurement is based on the slot boundary of the second cell.

In a possible implementation manner, the method for the terminal device to determine the symbols participating in the RSSI measurement includes: determining, by the terminal device, M number of consecutive N time slots starting from the first time slot covered by the SMTC window according to the measurement time slot information. The valid time slot, and then the terminal device determines the symbols participating in the RSSI measurement in M valid time slots according to the end symbol information. M and N are integers greater than 0, and M≤N. The symbols participating in the RSSI measurement are all covered by the SMTC window, and the last one of the N consecutive time slots is not covered by the SMTC window. The length of the SMTC window is N time slots, the length of the bit bitmap is N bits, and N bits are used to map N consecutive time slots.

Specifically, the time slot or symbol is covered by the SMTC window means that the start time of the time slot or symbol is not earlier than the start time of the SMTC window, and the end time is not later than the end time of the SMTC window. The terminal device first determines the first time slot covered by the SMTC window based on the timing of the second cell and the SCS information of the SSB, and then maps N consecutive time slots from the first time slot according to the number of bits N of the bitmap; Because the time slot boundaries of the first cell and the second cell are not aligned, and the SMTC window is N time slots, the last time slot of the N consecutive time slots is not covered by the SMTC window, that is, N consecutive time slots Part of the last time slot in the fall outside the SMTC window. The terminal device determines M valid time slots in N time slots according to the value of each bit in the bitmap. For example, when the bit value is "1", the time slot mapped by the bit is a valid time slot, and when the bit value is "0", the time slot mapped by the bit is not a valid time slot. The terminal device then determines the OFDM symbols participating in the RSSI measurement in the determined M valid time slots according to the end symbol information. For example, it is determined according to the mapping table shown in Table 1 that the value of the end symbol information corresponds to the OFDM symbols requiring RSSI measurement.

For example, as shown in Figure 3, the bitmap contains 10 bits, and the bits in the bitmap are: 1001010111, SSB = SCS = 30kHz, and the length of the time slot is 0.5ms based on SSB and the length of the SMTC window is 5ms, SMTC window length is equal to the length of 10 time slots. The timing reference of the SMTC window is the first cell, and the timing reference of the RSSI measurement is the second cell. The slot boundaries between the first and second cells are not aligned, that is, the boundaries of the SMTC window and the slot boundaries of the second cell are not aligned. Aligned. The terminal device determines that the first time slot covered by the SMTC window in the second cell is time slot 3, and then the terminal device maps 10 consecutive time slots in the second cell starting with time slot 3 according to the number of bits in the bitmap as: Time slot 3 to time slot 12. The mapping between the bitmap and time slots is shown in Table 2:

1	0	0	1	0	1	0	1	1	1

When the bit value is 0, the mapped time slot is not a valid time slot. According to Table 2 It can be concluded that time slot 3, time slot 6, time slot 8, time slot 10, time slot 11 and time slot 12 are valid time slots, and time slot 12 is not covered by the SMTC window. The terminal device performs a look-up table based on the end symbol information to determine the symbols participating in the RSSI measurement in the valid time slots described above. For time slot 12, the OFDM symbols participating in the RSSI measurement in time slot 12 only include the symbols covered by the SMTC window. For example, the value of the end symbol information is 0. It is learned from the table that the symbols participating in the RSSI measurement in slot 12 are symbols 0 to 11 but only symbols 0 to 5 in slot 12 are covered by the SMTC window, so In slot 12, only symbols 0 to 5 participate in the RSSI measurement.

In a possible implementation manner, the process by which the terminal device determines to participate in the RSSI measurement includes: the terminal device determines M valid times in consecutive N time slots starting from the first time slot covered by the SMTC window according to the measurement time slot information.

Specifically, the time slot or symbol is covered by the SMTC window means that the start time of the time slot or symbol is not earlier than the start time of the SMTC window, and the end time is not later than the end time of the SMTC window. The terminal device first determines the first time slot covered by the SMTC window based on the timing of the second cell and the SSBSCS, and determines the first N bits of the N + 1 bits in the bitmap, and then the terminal device uses the first time slot Begin to determine N consecutive time slots in the second cell. Since the length of the SMTC window is N + 1 time slots, all N consecutive time slots are covered by the SMTC window. Then, the terminal device determines M effective time slots in N consecutive time slots according to the determined value of the N bits, and the terminal device determines orthogonal frequency division multiplexing to participate in RSSI measurement in the M effective time slots according to the end symbol information. (orthogonal frequency division multiplexing, OFDM) symbols.

For example, referring to FIG. 4, N = 9, the SCS of the SSB is 30 kHz, and thus the length of the time slot is 0.5 ms, and the length of the SMTC window is 5 ms. Therefore, the length of the SMTC window is equal to the length of 10 time slots. The timing reference of the SMTC window is the first cell, and the timing reference of the RSSI measurement is the second cell. The terminal device first determines that the first time slot covered by the SMTC window is time slot 3. The bitmap contains 10 bits as "1001010111", and the terminal device determines the first 9 bits "100101011" from the 10 bits. The terminal device maps 9 time slots in the second cell starting from time slot 3 according to the 9 bits: time slot 3 to time slot 11, where the mapping relationship between 9 bits and time slots is as described in representation 3:

1	0	0	1	0	1	0	0	1
Time slot 3	Time slot 4	Time slot 5	Time slot 6	Time slot 7	Time slot 8	Time slot 9	Time slot 10	Time slot 11

In another possible implementation manner, the process of determining the terminal device to participate in the RSSI measurement includes: the terminal device is in the first time slot based on the timing of the second cell and the SCS information of the SSB covered by the SMTC window according to the measurement time slot information. M effective time slots are determined in the first N consecutive time slots; the terminal device determines the symbols participating in the RSSI measurement in the M effective time slots according to the RSSI measurement configuration information.

The length of the bitmap corresponding to the measurement time slot is N + 1. Bits, the next N slots of the N + 1 bits are used to map the N slots.

Specifically, the time slot or symbol is covered by the SMTC window means that the start time of the time slot or symbol is not earlier than the start time of the SMTC window, and the end time is not later than the end time of the SMTC window. The terminal device first determines the first time slot of the SCS-based SCS covered by the SMTC window and the next N bits of the N + 1 bits in the bitmap. Then the terminal device uses the The first time slot starts to determine N consecutive time slots in the second cell. Since the length of the SMTC window is N + 1 time slots, all N consecutive time slots are covered by the SMTC window. Then, the terminal device determines M valid time slots in N consecutive time slots according to the determined value of the N bits, and the terminal device determines OFDM symbols participating in the RSSI measurement in the M valid time slots according to the end symbol information.

For example, referring to FIG. 5, N = 9, the SCS of the SSB is 30 kHz, and thus the length of the time slot is 0.5 ms, and the length of the SMTC window is 5 ms. Therefore, the SMTC window includes 10 time slots. The timing reference of the SMTC window is the first cell, and the timing reference of the RSSI measurement is the second cell, that is, the terminal device needs to perform RSSI measurement on the second cell. The terminal device first determines that the first time slot covered by the SMTC window in the second cell is time slot 3. The bitmap contains 10 bits as "1001010111", and the terminal device determines the next 9 bits from the 10 bits "001010111". The terminal device maps nine time slots in the second cell starting from time slot 3 based on the nine bits: time slot 3 to time slot 11, where the mapping relationship between the nine bits and time slots is as described in representation 4:

0	0	1	0	1	0	1	1	1
Time slot 3	Time slot 4	Time slot 5	Time slot 6	Time slot 7	Time slot 8	Time slot 9	Time slot 10	Time slot 11

Table 4

Then, the terminal device determines the valid time slots according to the value of the bits: time slot 5, time slot 7, time slot 9, time slot 10, and time slot 11, and then the terminal device determines participation in the above valid time slots according to the end symbol information. The OFDM symbols measured by RSSI are not repeated here.

It can be seen from the above description that when the timing reference of the SMTC window and the timing reference of the RSSI measurement are different, the later multiple bits in the bitmap and the first cell based on the timing of the second cell and the SCS of the SSB covered by the SMTC window Multiple timeslots starting from each timeslot are mapped, and the mapping relationship between the measurement timeslot information and the timeslots in the SMTC window is clear, and the terminal device can accurately perform RSSI measurement on the specified time domain resource.

In another possible implementation manner, the process of determining the terminal device to participate in the RSSI measurement includes: the terminal device is in the first time slot based on the timing of the second cell and the SCS information of the SSB covered by the SMTC window according to the measurement time slot information. M effective time slots are determined in the first N consecutive time slots; the terminal device determines the symbols participating in the RSSI measurement in the M effective time slots according to the RSSI measurement configuration information. M and N are integers greater than 0, and M ≦ N. The bitmap corresponding to the measurement time slot information contains N bits. The N bits are used to map N consecutive time slots. The length of the SMTC window is N + 1 time slots, and the N time slots are covered by the SMTC window.

Specifically, the time slot or symbol is covered by the SMTC window means that the start time of the time slot or symbol is not at the start time of the SMTC window, and the end time is not later than the end time of the SMTC window. The terminal device first determines the first time slot of the SCS-based SCS covered by the SMTC window, and then determines N consecutive time slots in the second cell based on the first time slot. The length of the window is N + 1 time slots, so the determined N time slots are covered by the SMTC window. The terminal device then determines M valid time slots in N consecutive time slots according to the value of the N bits, and the terminal device determines the OFDM symbols participating in the RSSI measurement in the M valid time slots according to the end symbol information.

For example, referring to FIG. 6, N = 10, the SCS of the SSB is 30 kHz, and thus the length of the time slot is 0.5 ms, and the length of the SMTC window is 10 time slots. The timing reference of the SMTC window is the first cell, and the timing reference of the RSSI measurement is the second cell, that is, the terminal device needs to perform RSSI measurement on the second cell. The terminal device first determines that the first time slot covered by the SMTC window in the second cell is time slot 3. The bitmap contains 9 bits: 001010111, and the terminal device maps 9 time slots in the second cell starting from time slot 3 based on the 9 bits: time slot 3 to time slot 11, of which 9 bits and The mapping relationship is as described in representation 4:

0	0	1	0	1	0	1	1	1
Time slot 3	Time slot 4	Time slot 5	Time slot 6	Time slot 7	Time slot 8	Time slot 9	Time slot 10	Time slot 11

table 5

Based on the timing of the second cell and multiple time slots starting from the first time slot of the SCS SCS, the mapping relationship between the measurement time slot information and the time slots in the SMTC window is clear, and the terminal device can accurately determine the time Perform RSSI measurement on domain resources.

In yet another possible implementation manner, the process for the terminal device to determine the symbols participating in the RSSI measurement includes: the terminal device firstly overlaps with the SMTC window based on the timing of the second cell and the SCS information of the SSB according to the measurement time slot information. M timeslots are determined in N consecutive timeslots beginning with each timeslot. The terminal device determines the symbols participating in the RSSI measurement among the M timeslots based on the end symbol information. The symbols participating in the RSSI measurement are all covered by the SMTC window. . M and N are integers greater than 0, M ≦ N, the length of the SMTC window is N time slots, and the first time slot of the N consecutive time slots is not covered by the SMTC window.

Specifically, the overlap of the time slot / symbol and the SMTC window indicates that the start time of the time slot / symbol is not later than the end time of the SMTC window, and the end time is not earlier than the start time of the SMTC window. The timing reference of the SMTC window is the first cell, and the timing reference of the RSSI measurement is the second cell, that is, the terminal device performs RSSI measurement on the second cell. The terminal device first determines the first time slot overlapping with the SMTC window in the second cell, and then the terminal device maps N consecutive time slots in the second cell from the first time slot according to the number of bits of the bitmap. The terminal device determines M valid time slots in N consecutive time slots according to the value of the bit, and the terminal device determines the OFDM symbols participating in the RSSI measurement in the M valid time slots according to the end symbol information.

The bitmap contains 10 bits. Each bit in the bitmap is: 1001010111, SSB = SCS = 30kHz. According to SSB, the length of the slot is 0.5ms, the length of the SMTC window is 5ms, and the SMTC window contains 10 bits. Gap. The timing reference of the SMTC window is the first cell, and the timing reference of the RSSI measurement is the second cell. The time slot boundary between the first cell and the second cell is not aligned, that is, the boundary of the SMTC window and the time slot boundary of the second cell are not aligned. Aligned. The terminal device determines that the first time slot overlapping the SMTC window in the second cell is time slot 2, and then the terminal device maps 10 consecutive time slots in the second cell starting from time slot 2 according to the number of bits in the bitmap as : Time slot 2 to time slot 11. The mapping between the bitmap and time slots is shown in Table 6:

1	0	0	1	0	1	0	1	1	1
Time slot 2	Time slot 3	Time slot 4	Time slot 5	Time slot 6	Time slot 7	Time slot 8	Time slot 9	Time slot 10	Time slot 11

Table 6

The terminal device determines the valid time slot according to the value of each bit in the bitmap. When the bit value is 1, the mapped time slot is a valid time slot. When the bit value is 0, the mapped time slot is not a valid time slot. According to Table 2 It can be concluded that time slot 2, time slot 5, time slot 7, time slot 9, time slot 10, and time slot 11 are valid time slots, and time slot 2 is not covered by the SMTC window. The terminal device performs a look-up table based on the end symbol information to determine the symbols participating in the RSSI measurement in the above valid time slot. For the time slot 2, the OFDM symbols participating in the RSSI measurement in the time slot 2 only include the symbols covered by the SMTC window. For example, the value of the end symbol information is 0. It is learned from the table that the symbols participating in the RSSI measurement in slot 2 are symbols 0 to 11 but only symbols 6 to 11 in slot 2 are covered by the SMTC window. In slot 2 only symbols 6 to 11 participate in the RSSI measurement.

It can be seen from the above description that when the timing reference of the SMTC window and the timing reference of the RSSI measurement are different, the bitmap and the first slot of the SCS information based on the timing of the second cell and the SSB that overlap with the SMTC window For N consecutive time slots at the beginning of the slot, the mapping relationship between the measurement time slot information and the time slots in the SMTC window is clear, and the terminal device can accurately perform RSSI measurement on the specified time domain resource.
