technical field

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

Background technique

In a new radio access technology (NR) communication system, user equipment (UE) needs to support mobility processes such as cell selection, cell reselection, and cell handover to realize the mobility of the UE. The UE needs to measure related parameters. For example, the UE needs to measure the parameters in the mobility process, including: synchronization signal-reference signal reception power (SS-RSRP), synchronization signal-signal-to-interference-noise ratio (synchronization signal-to-interference-noise ratio). signal-signal to interference plusnoise ratio, SS-SINR), channel state information-reference signal reception power (CSI-RSRP), channel state information-signal to interference ratio (channel state information-signal to interference) plus noise ratio, CSI-SINR). Wherein, SS-RSRQ is the signal power of the synchronization signal (synchronization signal, SS) or physical broadcast channel-demodulation reference signal (physical broadcast channel-demodulation reference signal, PBCH-DMRS) received by the UE from a certain cell. Therefore, 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 NR communication systems is currently under discussion.

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

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

The terminal device receives the RSSI measurement configuration information, the subcarrier interval SCS information of the synchronization signal block SSB, and the synchronization signal measurement timing configuration (SMTC) information from the network device; the terminal device determines according to the timing of the first cell and the SMTC information The time domain position of the SMTC window for the current RSSI measurement. The SMTC information is used to indicate the configuration of the SMTC window for the current RSSI measurement. The SMTC information may include the SMTC window period, the SMTC window length, and the SMTC window offset. 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 measurements on the determined symbols.

The timing reference of the SMTC window is the first cell, indicating that the first cell is the timing reference cell of the SMTC window, and the time slot boundary of the SMTC window is based on the time slot boundary of the first cell; the timing reference of the SMTC window is the second cell. The second cell is the timing reference cell for RSSI measurement, and the time slot boundary of the RSSI measurement is based on the time slot boundary of the second cell.

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

Wherein, 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 time slot participating in the RSSI measurement in the time slot. Location of orthogonal frequency division multiplexing (OFDM) symbols.

The fact that a certain symbol/time slot is covered by the SMTC window means that the start time of the symbol/time 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, when determining the symbol participating in the RSSI measurement in the SMTC window, the timing reference of the SMTC window and the timing of the RSSI measurement are considered, so as to accurately determine the RSSI participation in the SMTC window. The position of the measured symbols improves the accuracy of the RSSI measurement.

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 identified to participate in the RSSI measurement include:

According to the RSSI measurement configuration information, the timing of the second cell, and the SCS information of the SSB, the terminal device determines M valid time slots from N consecutive time slots starting from the first time slot covered by the SMTC window; The RSSI measurement configuration information determines the symbols participating in the RSSI measurement in M valid time slots. The terminal device determines the symbols participating in the RSSI measurement in the 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 time slots mapped by the bitmap, so as to ensure that each bit in the bitmap can be mapped to one The mapping relationship between time slots, bitmaps and time slots within the SMTC window is clear.

In summary, when the timing reference of the SMTC window is different from the timing reference of the RSSI measurement, the following bits in the bitmap start with the first time slot of the SCS based on the timing of the second cell and the SSB covered by the SMTC window. The mapping relationship between the measurement time slot information and the time slots in the SMTC window is clear, and the terminal equipment can accurately measure the RSSI on the designated time domain resources.

In a possible design, the RSSI measurement configuration information includes a bitmap, the bitmap includes N bits, and the N bits are used to map N consecutive time slots, and the length of the SMTC window is N+1 time slots, so The N consecutive time slots are covered by the SMTC window. When the timing reference of the SMTC window is different from the timing reference of the RSSI measurement, the number of bits in the bitmap is less than the number of time slots included in the SMTC window, and the bitmap is different from the timing sum based on the second cell covered by the SMTC window.

Detailed ways

FIG. 1a is a schematic diagram of an architecture of a communication system involved in an embodiment of the present invention, where the communication system includes a network device and a terminal device. Figure 1a shows a network device communicating with a terminal device. The communication system may be a global system for mobile communication (GSM), a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) system, a global microwave interconnection access (worldwide interoperability for microwave access, WiMAX) systems, long term evolution (long term evolution, LTE) systems, 5G communication systems (such as new radio (NR) systems, communication systems that integrate multiple communication technologies (such as LTE technology) and NR technology fusion communication system), or the subsequent evolution communication system. The form and quantity of the base station and terminal equipment shown in Fig. 1a are only for example, and do not constitute a limitation to the embodiments of the present invention.

The terminal device in this application is a device with wireless communication function, which can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; it can also be deployed on water (such as ships, etc.); it can also be deployed on In the air (such as on airplanes, balloons, and satellites). The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, an industrial control (industrial) terminal device. Wireless terminals in control), wireless terminals in self-driving, wireless terminals in remote medical, wireless terminals in smart grid, wireless terminals in transportation safety, Wireless terminals in smart cities, wireless terminals in smart homes, and so on. The terminal device may also be a handheld device, vehicle-mounted device, wearable device, computing device, or other processing device connected to a wireless modem with wireless communication capabilities. Terminal equipment can be called by different names in different networks, for example: terminal equipment, access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile equipment, user terminal, terminal, wireless communication Devices, user agents or user devices, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistant (PDA), 5G network or terminal equipment in the future evolution network, etc.

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

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, which includes the measurement slot information (measurementSlot) and the end symbol. message (endSymbol).

Exemplarily, the measurement time slot information is a bitmap (bitmap), the bitmap contains multiple bits, each bit maps a time slot in the SMTC window, and the bitmap is one-to-one with the time slot in the SMTC window. Mapping relationship, the length of the time slot is determined by the SCS of the SSB. Specifically, when the SCS of the SSB is 15*2 ^μ kHz, the length of one time slot is 2- ^μ ms, and μ is an integer greater than or equal to 0. The value of each bit is used to determine the time slot participating in the RSSI measurement among the multiple time slots mapped, which is called an effective time slot in this embodiment. For example, if the value of the bit is 1, it means that the time slot mapped by the bit is a valid time slot, and this time slot needs to participate in RSSI measurement; the value of the bit is 0, it means that the time slot mapped by the bit is not a valid time slot, and the time slot is not valid. Slots do not need to participate in RSSI measurements.

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

The value of the end symbol information Symbol index 0 {0,1} 1 {0,1,2,..,10,11} 2 {0,1,2,…,5} 3 {0,1,2,…,7}

Table 1

Wherein, how the measurement time slot information and the time slots in the SMTC window are mapped is related to the timing reference of RSSI measurement, and the timing reference of RSSI measurement is determined according to the following principles:

1. For the measurement of the same frequency frequency point, the timing reference of RSSI measurement is the serving cell on the frequency point;

2. For the measurement of different frequency points, the timing reference of RSSI measurement is any cell on the frequency point.

The same-frequency frequency point refers to the frequency point where the serving cell is located. In the non-carrier aggregation (CA) and non-dual connectivity (DC) scenarios, the serving cell refers to the primary cell ( PCell). In the CA or DC scenario, the serving cell includes a primary cell, a primary and secondary cell (PSCell), and all secondary cells (SCell). Different frequency points represent frequencies other than the same frequency point.

The mapping mode between the measurement time slot information and the time slots in the SMTC window is not only related to the timing reference of RSSI measurement, but also related to the timing reference of the SMTC window. For example, in an NR communication system, the timing reference of the SMTC window is a specific cell (special cell, SpCell) of the NR, and SpCell refers to a primary cell (Pcell) or a primary secondary cell (PSCell). Therefore, in a non-standalone (non-standalone, NSA) scenario, the NRSpCell refers to the PSCell of the NR. In an independent deployment (standalone, SA) scenario, the NR SpCell refers to the PCell of the NR. For the same-frequency measurement at the frequency point where the SCell is located and the inter-frequency measurement process at different frequency points, it may occur that the mapping relationship between the measurement time slot information and each slot in the SMTC window is not clear. The following describes how to map the measurement time slot information and each time slot in the SMTC window in the process of intra-frequency measurement and inter-frequency measurement.

Scenario 1: For the same-frequency measurement at the frequency point 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 measurement time slot information and each time slot in the SMTC window during the same-frequency measurement of the frequency point where the SpCell is located. Assuming that the length of the SMTC window is 5ms, the The subcarrier spacing (SCS) is 30 kHz, and the length of the time slot is 0.5 ms according to the SCS of the SSB. Since the timing reference of RSSI measurement is the same as that of the SMTC window, the boundary of the SMTC window is aligned with the time slot boundary of the SpCell. At this time, the time slot information (bit map) is measured and the time slot in the SMTC window is between The mapping relationship is clear, and the terminal device can accurately determine the position of the time domain resources participating in the RSSI measurement in the SMTC window according to the RSSI measurement configuration information.

Scenario 2: For intra-frequency measurement at the frequency where the SCell is located, the timing reference of the SMTC window is the NR SpCell (the first cell), but the timing reference of the RSSI measurement is the serving cell on this frequency, that is, the Scell (the second cell). The timing of the NR SpCell and the timing of the SCell may not be consistent. For example, in the intra-band noncontiguous NR CA scenario, the maximum reception timing difference (MRTD) between cells is 3 microseconds; while in the inter-band NR CA scenario, the timing difference between cells may be Up to 33 microseconds (in the case of FR1). Therefore, it may happen that the boundary of the SMTC window is not aligned with the boundary of the time slot as shown in Fig. 1c. Assuming that the length of the SMTC window is 5ms, the SCS of the SSB is 30kHz, and the length of the time slot obtained from the SCS of the SSB is 0.5ms, the number of complete time slots in the SMTC window based on the timing of the second cell is: Length×(SSB’s SCS/15)-1=9, and the length of the measurement slot information (bit map) is: SMTC window length×(SSB’s SCS/15)=10, the measurement slot information (bit The mapping relationship between the time slot in the SMTC window and the time slot in the SMTC window is not clear, so that the UE cannot accurately determine the position of the time domain resource participating in the RSSI measurement in the SMTC window.

Scenario 3: For inter-frequency measurement of non-serving frequency points, the difference between the timing reference of RSSI measurement and the timing reference of NR SpCell is larger than the case of intra-frequency measurement. First, the difference in reception timing between the inter-frequency cell and the serving cell does not have any constraints in the 3GPP protocol; secondly, the timing reference cell for RSSI measurement during inter-frequency measurement can be any cell on the frequency point, and the UE selects the timing reference cell in the timing reference cell. Randomness in the timing can also lead to very large timing differences. The unclear mapping relationship between the measurement time slot information (bit map) and the time slots in the SMTC window may cause the UE to be unable to accurately determine the position of the time domain resources participating in the RSSI measurement in the SMTC window.

According to the above analysis, the current RSSI measurement process does not consider the difference between the timing reference of RSSI measurement and the timing reference of the SMTC window. In this case, the mapping relationship between the measurement time slot information and the time slots in the SMTC window is not It is clear that the UE cannot accurately determine the position of the time domain resources involved in RSSI measurement in the SMTC window. Therefore, how to specify the mapping relationship between the measurement time slot information and each time slot in the SMTC window is an urgent problem to be solved.

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

Referring to FIG. 2, it is a schematic flowchart of a method for measuring a reference signal strength indicator provided by 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 of the SSB and SMTC information to the terminal device, and the terminal device receives the RSSI measurement configuration information, SSB information and SMTC information from the network device.

Specifically, the RSSI measurement configuration information is used to indicate the time domain resources participating in the RSSI measurement within the SMTC window. In a possible implementation, the RSSI measurement configuration information includes measurement time slot information and end symbol information. For the definitions of the measurement time slot information and the end symbol information, reference may be made to the descriptions in the embodiments of FIG. 1a to FIG. 1c , which will not be repeated here. 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 represents 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 relative to the reference time point.

In a possible implementation manner, the network device configures RSSI measurement configuration information, SSB information and SMTC information for the terminal device through radio resource control (RRC) signaling in a connected state (connected). In yet another possible implementation manner, the network device in the idle/inactive state may configure RSSI measurement configuration information, SCS information of the SSB 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, the bitmap includes N bits, N=the length of the SMTC window/the length of the time slot -1, the length of the time slot is related to the SCS of the SSB, and the length of the SMTC window is related to the SCS of the SSB. The length is N+1 slots. The length of the SMTC window may be determined according to the SMTC information.

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

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

S203, the terminal device determines the symbol participating in the RSSI measurement.

Specifically, the terminal device first determines the bitmap according to the measurement time slot information included in the RSSI measurement configuration information, 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 determine the time slot participating in the RSSI measurement in the SMTC window according to the mapping relationship between the value of the bitmap and the time slot in the SMTC window, and then determine the time slot participating in the RSSI measurement according to the end symbol information. OFDM symbol for RSSI measurement. The timing reference of 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 not aligned.

The timing reference of RSSI measurement is the second cell, indicating that the second cell is a timing reference cell for RSSI measurement, and the time slot boundary of RSSI measurement is based on the time 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: the terminal device determines M consecutive N time slots starting from the first time slot covered by the SMTC window according to the measurement time slot information valid time slots, and then the terminal device determines the symbols participating in the RSSI measurement in the M valid time slots according to the end symbol information. M and N are integers greater than 0, M≤N, the symbols participating in the RSSI measurement are covered by the SMTC window, and the last time slot in 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 bitmap is N bits, and the N bits are used to map N consecutive time slots.

Specifically, that 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; wherein , because the time slot boundaries of the first cell and the second cell are not aligned, and the length of the SMTC window is N time slots, the last time slot in the N consecutive time slots is not covered by the SMTC window, that is, N consecutive time slots Part of the last slot in the SMTC window falls outside the SMTC window. The terminal device determines M valid time slots among the N time slots according to the value of each bit in the bitmap. For example, when the value of the bit is "1", the time slot mapped by the bit is a valid time slot, and when the value of the bit is "0", the time slot mapped by the bit is not a valid time slot. Then, the terminal device determines the OFDM symbols participating in RSSI measurement in the determined M valid time slots according to the end symbol information.

For example, as shown in Figure 3, the bitmap contains 10 bits, and the bits in the bitmap are: 1001010111, SSB SCS=30kHz, the length of the time slot obtained according to the SSB SCS is 0.5ms, and the length of the SMTC window is 5ms, the 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 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 Align. 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 from time slot 3 according to the number of bits of the bitmap: Time slot 3 to time slot 12. The mapping relationship between the bitmap and the time slot is shown in Table 2:

Table 2

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, and 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 table look-up according to the end symbol information to determine the symbols participating in the RSSI measurement in the above-mentioned valid time slots, wherein, for the time slot 12, the OFDM symbols participating in the RSSI measurement in the time slot 12 only include the symbols covered by the SMTC window. , for example: the value of the end symbol information is 0, and it is known by looking up the table that the symbols participating in RSSI measurement in time slot 12 are symbols 0 to 11, but only symbols 0 to 5 in time slot 12 are covered by the SMTC window, so In time slot 12, only symbols 0 to 5 participate in RSSI measurement.

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

Specifically, that 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. Initially, N consecutive time slots are determined in the second cell. Since the length of the SMTC window is N+1 time slots, the N consecutive time slots are all covered by the SMTC window. Then, the terminal device determines M effective time slots in N consecutive time slots according to the determined values of N bits, and the terminal device determines the orthogonal frequency division multiplexing participating 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 30kHz, the length of the time slot is 0.5ms, and the length of the SMTC window is 5ms, so 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 equipment 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, wherein the mapping relationship between the 9 bits and the time slot is as described in expression 3:

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

For example, when the value of the bit is 1, the time slot mapped by the bit is a valid time slot, and when the value of the bit is 0, the time slot mapped by the bit is the valid time slot. The slot is not a valid time slot. According to the mapping relationship in Table 3, it can be known that the valid time slots are: time slot 3, time slot 6, time slot 8, time slot 9 and time slot 11.

Specifically, that 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 on the timing of the second cell and the SSB covered by the SMTC window, and determines the next N bits of the N+1 bits in the bitmap, and then the terminal device uses this time slot. 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, the N consecutive time slots are all covered by the SMTC window. Then, the terminal device determines M valid time slots in N consecutive time slots according to the determined values of the N bits, and the terminal device determines the OFDM symbols participating in 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, the length of the time slot is 0.5 ms, and the length of the SMTC window is 5 ms, so the SMTC window contains 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 equipment 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 terminal equipment 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, wherein the mapping relationship between the 9 bits and the time slot is as described in Representation 4:

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

Table 4

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

As can be seen from the above description, when the timing reference of the SMTC window and the timing reference of RSSI measurement are different, the following bits in the bitmap are different from the timing of the second cell covered by the SMTC window and the first SCS of the SSB based on the timing of the second cell. Multiple time slots starting from each time slot 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 measure RSSI on the designated time domain resources.

In yet another possible implementation manner, the process for the terminal device to determine to participate in the RSSI measurement includes: the terminal device uses the measurement time slot information in the first time slot covered by the SMTC window based on the timing of the second cell and the SCS information of the SSB. M valid 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 valid 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 includes 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, and the N time slots are covered by the SMTC window.

Specifically, that 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 on the timing of the second cell and the SSB covered by the SMTC window, and then determines N consecutive time slots in the second cell according to the first time slot. The length of the window is N+1 time slots, so the determined N time slots are all covered by the SMTC window. Then, the terminal device 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 RSSI measurement in the M valid time slots according to the end symbol information.

For example, as shown in FIG. 6, N=10, and the SCS of the SSB is 30 kHz, so 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 equipment 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 according to the 9 bits: time slot 3 to time slot 11, among which 9 bits and time slots The mapping relationship is as described in Representation 4:

0 0 1 0 1 0 1 1 1 slot 3 slot 4 slot 5 slot 6 slot 7 slot 8 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 of the SSB, 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 RSSI measurements are performed on domain resources.

The timing reference of the SMTC window is the first cell, and the timing reference of 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 Align. 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. : Time slot 2 to time slot 11. The mapping relationship between the bitmap and the time slot is shown in Table 6:

1 0 0 1 0 1 0 1 1 1 slot 2 slot 3 slot 4 slot 5 slot 6 slot 7 slot 8 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, and 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 table look-up according to the end symbol information to determine the symbols participating in the RSSI measurement in the above-mentioned valid time slots. For 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, and it is known by looking up the table that the symbols involved in RSSI measurement in time slot 2 are symbols 0 to 11, but only symbols 6 to 11 in time slot 2 are covered by the SMTC window, so In time slot 2, only symbols 6 to 11 participate in RSSI measurement.
