[0137] In some embodiments of this disclosure, the performance of sensing accuracy and sensing resolution depends on the design of the sensing reference signal. Generally speaking, the larger the sensing bandwidth, the higher the sensing distance accuracy and resolution; the longer the duration of the sensing signal, the higher the sensing speed accuracy and resolution. Therefore, for different sensing targets and sensing requirements, the sensing signal needs to be specially designed and multiplexed with the communication signal. Common resource multiplexing methods include time division multiplexing, frequency division multiplexing, and space division multiplexing.
[0138] In some embodiments, when the sensing signal and the communication signal employ frequency division multiplexing, that is, on the same port and the same (overlapping) time domain resources, the sensing signal and the communication signal are transmitted on different frequency domain resources respectively. Figure 1B is a schematic diagram of a sensing link and a communication link in an ISAC scenario according to an embodiment of the present disclosure. As shown in Figure 1B, in an ISAC scenario, the target to be sensed and the target to be communicated are usually not in the same location, therefore the beams of the sensing signal and the communication signal need to cover different directions respectively.
[0139] In some embodiments, when sensing signals and communication signals are transmitted using frequency division multiplexing, the resources for sensing signals and communication signals are configured on the same symbol. As shown in Figure 1B, taking a TRP-UE bi-static (dual-station) as an example, the sensing target and the communication UE are located at different positions, so the transmission beams of the sensing signals and communication signals may point in different directions. Figure 1C is a beam diagram according to an embodiment of this disclosure. As shown in Figure 1C, due to port limitations, the UE can generally only transmit / receive one analog beam at a time. Therefore, at any given moment, the UE can only select one beam for signal transmission / reception. If the sensing signals and communication signals are configured on the same symbol, the UE needs to consider the reception priority of the sensing signals and communication signals.
[0140] In some embodiments, when the Synchronization Signal Block (SSB) shares the same symbol with the Demodulation Reference Signal-Physical Downlink Shared Channel (DMRS-PDSCH):
[0141] SSB takes precedence. In the case of mTRP, one TCI codepoint activates two TCI states, and at least one DMRS (PDSCH) port is Quasi-Co-Location (QCL) type-D with the SSB.
[0142] In some embodiments, when the Channel State Information-Reference Signal (CSI-RS) and the Demodulation Reference Signal-Physical Downlink Control Channel (DMRS-PDCCH) share the same symbol:
[0143] PDCCH takes precedence. If PDCCH activates two TCI states, the first one is used as the default QCL relationship.
[0144] In some embodiments, when CSI-RS and SSB share the same symbol: SSB takes precedence.
[0145] In some embodiments, when the Sounding Reference Signal (SRS) is in the same slot as the Physical Uplink Shared Channel (PUSCH) / Physical Uplink Control Channel (PUCCH):
[0146] If the PUSCH priority indicator in the Downlink Control Information (DCI) is 0, the SRS is sent after the PUSCH.
[0147] If the PUSCH priority indicator in the DCI is 1, the UE will not send SRS.
[0148] In some embodiments, the following conventions apply to the priority indication of the Positioning Reference Signal (PRS) and the communication signal / channel:
[0149] For cases where DL PRS is received outside the measurement gap but within the downlink PRS processing window, the UE determines the priority of DL PRS based on the higher-layer parameter priority, which depends on the UE's capabilities or the priority implied by the UE's capabilities, except in the case of SSB:
[0150] When the value is "st1", DL PRS has higher priority than all DL signals and channels; or,
[0151] When the value is "st2", the priority of DL PRS is lower than that of PDCCH and PDSCH scheduled by DCI formats 1_1, 1_2, 1_3, or 4_2, where the priority indicator field in these DCI formats is set to 1. Meanwhile, the priority of DL PRS is higher than that of other DL signals and channels; or...
[0152] When the value is "st3", the priority of DL PRS is lower than that of all DL signals and channels.
[0153] In some embodiments, a signal / channel priority solution is provided when different communication signals / channels overlap in the time domain, but the special characteristics of the integrated sensing scenario are not considered, for example:
[0154] When communication signals / channels and sensing signals overlap in symbol, the signal priority is not determined;
[0155] The priority definitions for different sensing reference signal symbols are not yet determined.

[0157] Step S2101: The sensing receiver 101 determines the weight value of the time domain unit where the sensing signal is located.
[0158] In some embodiments, the time-domain unit can be a symbol or a time slot, and this disclosure does not limit this.
[0159] In some embodiments, FIG2B is a schematic diagram of a time-domain unit according to an embodiment of the present disclosure. As shown in FIG2B, the time-domain unit occupied by the sensed signal in the time domain is the shaded area.
[0160] In some embodiments, the set of time-domain units contained in the sensed signal in the time domain can be used as... express.
[0161] In some embodiments, the time-domain unit contained in the sensing signal in the time domain can also be understood as the time-domain unit occupied by the sensing signal in the time domain.
[0162] In some embodiments, The corresponding set of differential co-array (DCA) domains can be represented as:
[0163] in, for The corresponding DCA domain sets, n1 and n2 respectively represent The location of the time-domain unit in the figure is shown in Figure 2B. The intermediate time-domain units include #1, #2, #3, #4, #8, and #12.
[0164] In some embodiments, the sensing receiver 101 can determine the weight function of the sensing signal, and determine the weight value of the time domain unit where the sensing signal is located based on the weight function, the position of the time domain unit where the sensing signal is located, and the first interval threshold.
[0165] In some embodiments, the weight function is used to determine the number of time-domain cell combinations corresponding to different time-domain cell intervals.
[0166] For example, if the time-domain cell spacing is m, then the combination of time-domain cells is a pair of time-domain cells with a time-domain cell spacing of m. For instance, if there are 5 pairs of time-domain cells with a time-domain cell spacing of m, the number of time-domain cell combinations corresponding to the time-domain cell spacing m is 5.
[0167] In some embodiments, the time-domain cell interval can also be called the time-domain cell spacing. Taking a time slot as an example, the time-domain cell interval between two adjacent time slots is 1, and the time-domain cell interval between time slot #1 and time slot #3 is 2 or -2.
[0168] In some embodiments, the weight function can be expressed as:
[0169] Where m is the time-domain cell interval, and w(m) represents... The number of time-domain unit combinations with a time-domain unit spacing of m.
[0170] As shown in Figure 2B, when m = 1, the time-domain cell combinations include (#2,#1), (#3,#2), and (#4,#3), and the number of time-domain cell combinations with a time-domain cell interval of 1 is 3. When m = 2, the time-domain cell combinations include (#3,#1) and (#4,#2), and the number of time-domain cell combinations with a time-domain cell interval of 2 is 2.
[0171] In some embodiments, the sensing receiver 101 can determine a first weight value and a second weight value based on the weight function, the position of the time domain unit where the sensing signal is located, and a first interval threshold, and determine the weight value of the time domain unit where the sensing signal is located based on the first weight value and the second weight value.
[0172] In some embodiments, the sensing receiver can determine the first weight value according to the following formula:
[0173] Where g1(n) is the first weight value, n represents the position of the nth time-domain unit where the sensed signal is located, and n′ is... The time domain unit that is different from the time domain unit where the sensing signal is located, η is the first interval threshold.
[0174] In some embodiments, the first interval threshold may be a protocol agreement or a network device configuration, and this disclosure does not limit this. For example, the first interval threshold may be 2.
[0175] As shown in Figure 2B, if the first interval threshold is 2, then w(m)≤2. According to formula (2), the values of m that satisfy w(m)≤2 are -11, -10, -9, -8, -7, -6, -5, -4, -3, -2, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. The time-domain cell combination for m = -11 includes (#1, #12), the time-domain cell combination for m = -10 includes (#2, #12), the time-domain cell combination for m = -9 includes (#3, #12), the time-domain cell combination for m = -8 includes (#4, #12), the time-domain cell combination for m = -7 includes (#1, #8), the time-domain cell combination for m = -6 includes (#2, #8), the time-domain cell combination for m = -5 includes (#3, #8), the time-domain cell combination for m = -4 includes (#4, #8) and (#8, #12), the time-domain cell combination for m = -3 includes (#1, #4), and the time-domain cell combination for m = -2 includes (#1, #3) and (#2, #4). The time-domain unit combinations for m=2 include (#3,#1) and (#4,#2); for m=3, they include (#4,#1); for m=4, they include (#8,#4) and (#12,#8); for m=5, they include (#8,#3); for m=6, they include (#8,#2); for m=7, they include (#8,#1); for m=8, they include (#12,#4); for m=9, they include (#12,#3); for m=10, they include (#12,#2); and for m=11, they include (#12,#1). If n=4, then g1(n) can be determined to be 8.
[0176] In some embodiments, the sensing receiver 101 can determine the second weight value according to the following formula:
[0177] Where g2(n) is the second weight value.
[0178] As shown in Figure 2B, if the first interval threshold is 2, then w(m)>2. According to formula (2), the value of m can be -1, 0, or 1. The time-domain unit combinations for m=-1 include (#1,#2), (#2,#3), and (#3,#4). The time-domain unit combinations for m=0 include (#1,#1), (#2,#2), (#3,#3), (#4,#4), (#8,#8), and (#12,#12). The time-domain unit combinations for m=1 include (#2,#1), (#3,#2), and (#4,#3). If n=4, then g2(n) can be determined to be 3.
[0179] In some embodiments, the sensing receiver 101 can determine the weight value of the time domain unit where the sensing signal is located according to the following formula:
[0180] Where g′(n) is the weight value of the time domain unit where the sensing signal is located.
[0181] As shown in Figure 2B, if the first interval threshold is 2 and n = 4, the calculated g1(n) is 8 and g2(n) is 3, then g′(n) can be determined to be 8 / 11.
[0182] In some embodiments, the sensing receiver 101 can determine the weight value of the time domain unit where the sensing signal is located according to the following formula:
[0183] Where g′(n) is the weight value of the nth time-domain unit where the sensed signal is located, and M is... The maximum time-domain interval corresponding to the time-domain unit in the array is T(n,m), which represents the number of times the nth time-domain unit appears in the combination of time-domain units with a time-domain interval of m.
[0184] As shown in Figure 2B, M is 11. Taking n=4 as an example, when m=-8, -4, -3, -2, -1, 0, 1, 2, 3, 4, 8, T(n,m)=1; when m=-11, -10, -9, -7, -6, -5, 5, 6, 7, 9, 10, 11, T(n,m)=0. The calculated g′(n) is 36 / 11.
[0185] In some embodiments, if The corresponding DCA domain set and If the corresponding DCA domain sets are different, then the weight value of the time domain unit where the sensed signal is located is the third weight value; if The corresponding DCA domain set and If the corresponding DCA domain sets are the same, then the weight value of the time domain unit where the sensed signal is located is the fourth weight value.
[0186] In some embodiments, From The set of remaining time-domain units of the sensed signal after deleting the time-domain unit containing the sensed signal. As shown in Figure 2B, if the time-domain unit containing the sensed signal is #1, then The included time-domain units are #2 to #12.
[0187] In some embodiments, the fourth weight value is less than the third weight value. For example, the third weight value is 1, and the fourth weight value is 0.
[0188] In some embodiments, The corresponding DCA domain set can be used express.
[0189] In some embodiments, if Then g′(n)=1; if Then g′(n)=0.
[0190] As shown in Figure 2B, if the time domain unit where the sensed signal is located is #1,
[0191] but
[0192] g′(n)=1.
[0193] Step S2102: The sensing receiver 101 determines the priority of the time domain unit where the sensing signal is located based on the weight value of the time domain unit where the sensing signal is located.
[0194] In some embodiments, if the weight value of the time domain unit where the sensing signal is located is greater than or equal to the first weight threshold, the time domain unit where the sensing signal is located has a high priority; if the weight value of the time domain unit where the sensing signal is located is less than the first weight threshold, the time domain unit where the sensing signal is located has a low priority.
[0195] In some embodiments, the first weight threshold may be a protocol agreement or a network device indication, and this disclosure does not limit this.
[0196] For example, the first weight threshold can be 0.8. If the weight of the time domain unit where the sensed signal is located is 1, then the time domain unit where the sensed signal is located has a high priority; if the weight of the time domain unit where the sensed signal is located is 0, then the time domain unit where the sensed signal is located has a low priority.

[0198] In some embodiments, the sensing receiver 101 receives the first information sent by the network device 102, but is not limited thereto. The sensing receiver 101 may also receive the first information sent by other entities, in which case step S2103 may be omitted.
