[0002] In sensing and communication processing, reference signals (RS) are used to sense target objects or determine information such as channel delay, angle, and Doppler. However, improving the estimation performance of this information and reducing the impact of errors (such as inconsistencies in phase, power, and delay) during the estimation process are still unknown; otherwise, insufficient estimation performance will result. The estimation of this information can be achieved by measuring RS at different times and / or frequency domain locations and processing them jointly.

[0068] To better understand the technical solution of this application, the following explains the integration of sensing.

[0069] Future mobile communication systems, such as B5G or 6G systems, will possess sensing capabilities in addition to communication capabilities. Sensing capabilities refer to the ability of one or more devices to sense the location, distance, and speed of target objects through the transmission and reception of wireless signals, or to detect, track, identify, and image target objects, events, or environments. With the deployment of small base stations with high-frequency, high-bandwidth capabilities such as millimeter waves and terahertz waves in 6G networks, the resolution of sensing will be significantly improved compared to centimeter waves, enabling 6G networks to provide more refined sensing services. Typical sensing functions and application scenarios are shown in Table 1.

[0070] Table 1

[0071]

[0072] Communication and sensing integration refers to the integrated design of communication and sensing functions within the same system through spectrum sharing and hardware sharing. While transmitting information, the system can sense information such as location, distance, and speed, and detect, track, and identify target devices or events. The communication system and the sensing system complement each other, thereby improving overall performance and bringing a better service experience.

[0073] The integration of communication and radar is a typical application of communication-sensing integration (communication-sensing fusion). In the past, radar systems and communication systems were strictly distinguished due to different research objects and focuses, and in most scenarios, the two systems were studied independently. In fact, radar and communication systems are both typical methods of information transmission, acquisition, processing, and exchange, and they share many similarities in terms of working principles, system architecture, and frequency bands. The design of integrated communication and radar systems is highly feasible, mainly in the following aspects: First, both communication and sensing systems are based on electromagnetic wave theory, using the transmission and reception of electromagnetic waves to complete information acquisition and transmission; second, both communication and sensing systems have structures such as antennas, transmitters, receivers, and signal processors, resulting in significant overlap in hardware resources; with technological advancements, their operating frequency bands also increasingly overlap; furthermore, they share similarities in key technologies such as signal modulation and reception detection, and waveform design. The integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, improved spectral efficiency, and reduced mutual interference, thereby improving the overall system performance.

[0074] Based on the different sending and receiving nodes of the sensing signal, sensing links are divided into the following six types, such as... Figure 2 As shown. It is worth noting that, Figure 2 Each sensing link in the example uses one sending node and one receiving node. In actual systems, different sensing links can be selected according to different sensing requirements. Each sensing link can have one or more sending nodes and receiving nodes, and the actual sensing system can include a variety of different sensing links. Figure 2 The objects of perception in the example are people and cars; in reality, the objects of perception in the actual system will be much more diverse.

[0075] 1) Base station self-transmitting and self-receiving sensing. In this method, the base station sends sensing signals and obtains the sensing results by receiving the echo of the sensing signals.

[0076] 2) Inter-base station air interface sensing. At this time, base station 2 receives the sensing signal sent by base station 1 and obtains the sensing result.

[0077] 3) Uplink air interface sensing. At this time, the base station receives the sensing signal sent by the UE and obtains the sensing result.

[0078] 4) Downlink air interface sensing. At this time, the UE receives the sensing signal sent by the base station and obtains the sensing result.

[0079] 5) Terminal self-transmitting and receiving sensing. In this case, the UE sends a sensing signal and obtains the sensing result by receiving the echo of the sensing signal.

[0080] 6) Sidelink sensing between terminals. For example, UE 2 receives sensing signals sent by UE 1 and obtains sensing results.

[0100] In the embodiments of this application, at least two second frequency domain ranges with adjacent frequency domain positions have overlapping frequency domain resources, thereby compensating for at least one offset in the phase, power, and delay of the first RS caused by the difference in frequency domains. The first RS transmitted in at least two second frequency domain ranges is transmitted simultaneously in at least a portion of the second time units, thereby ensuring that the error in frequency domain estimation is not affected by changes in channel time.

[0101] Optionally, the bandwidth of the second frequency domain range is related to the capabilities of the first device (such as terminal capabilities), which are the capabilities to maintain consistency in phase, and / or power, and / or delay.

[0105] All are sent simultaneously, meaning they occupy the same number of symbols (s).

[0106] Some symbols are sent simultaneously, meaning some symbols are the same.

[0107] Optionally, the second frequency domain range can be understood as a 'sub-band' or 'sub-channel'.

[0108] The first RS described in the embodiments of this application can be used for sensing, positioning, channel estimation, channel state information determination, channel detection, etc. The first RS described in the embodiments of this application can also be used for other functions, and this application is not limited thereto.

[0109] Optionally, the first RS can be a dedicated sensing signal, such as a sensing signal generated based on a Chirp or Frequency Modulated Continuous Wave (FMCW) signal, or a sensing signal generated based on a pseudo-noise (PN) sequence, a ZC (Zadoff Chu) sequence, or other sequences.

[0110] Optionally, the first RS can be a dedicated positioning signal, such as a positioning reference signal (PRS), a sounding reference signal (SRS), or an SRS for positioning.

[0111] Optionally, the first RS can be a demodulation reference signal (DMRS), a channel state information reference signal (CSI-RS), an SRS, a PRS, a tracking reference signal (TRS), etc.

[0114] It should be noted that in the integrated sensing and communication system, the sensing reference signal (RS) used to perceive the target object (such as the first RS) is used to sense information such as channel delay, angle, and Doppler effect. The Doppler estimation can be obtained by measuring the RS (such as the first RS) at different times and processing them jointly. The RS (such as the first RS) used for joint estimation at different times needs to ensure the consistency of target characteristics. Therefore, the design of the sensing RS (such as the first RS) should consider... Figure 4 As shown, RS (such as the first RS) at different times is divided into different time windows (such as the first time window). Within each time window, the consistency of the target characteristics transmitted by the RS (such as the first RS) is ensured to improve the performance of Doppler estimation. Furthermore, to estimate Doppler more accurately, RS (such as the first RS) from multiple time windows (such as the first time window) in the time domain can be considered for joint estimation, using the accumulation of RS (such as the first RS) over a longer period to estimate Doppler. However, phase consistency (taking phase as an example) cannot be guaranteed between different time windows (such as the first time window). Therefore, a corresponding method needs to be designed to compensate for the phase error between different time windows (such as the first time window). One approach is as follows... Figure 5As shown, adjacent time windows (such as the first time window) are overlapped in the time domain. The phase error between adjacent time windows (such as the first time window) is estimated based on the RS (such as the first RS) of the overlapping part. After compensating for the phase error between different time windows (such as the first time window), the Doppler is estimated by jointly using the RS (such as the first RS) of multiple time windows (such as the first time window). Alternatively, if adjacent time windows (such as the first time window) cannot overlap, then adjacent time windows (such as the first time window) need to be as close as possible, and the RS (such as the first RS or the second RS) near the boundary of adjacent time windows (such as the first time window) also need to be as close as possible. Since the RS (such as the first RS or the second RS) at the boundary of adjacent time windows (such as the first time window) are relatively close, the corresponding channel variation is small. Therefore, the phase error between adjacent time windows (such as the first time window) can be estimated based on the RS (such as the first RS or the second RS) at the boundary of adjacent time windows (such as the first time window). Therefore, it is necessary to configure RSs with relatively high time-domain density (such as the first RS or the second RS) at the boundary of adjacent time windows (such as the first time window) so that there are RSs (such as the first RS or the second RS) that are relatively close at the boundary of the time window (such as the first time window) to estimate the phase error between the two time windows (such as the first time window). Figure 6As shown. Furthermore, the phase compensation design described above can also be applied to the frequency domain. In future 6G communications, ultra-wideband is a key driving force for ultra-high data rate transmission. However, generating ultra-wideband waveforms (such as Orthogonal Frequency-Division Multiplexing (OFDM) waveforms) using a single large-bandwidth transmit chain will be challenging due to the need for high-speed and high-resolution digital-to-analog converters (DACs) / analog-to-digital converters (ADCs). One way to achieve large bandwidth with a single component carrier (CC) or a single bandwidth part (BWP) is to divide the large bandwidth into multiple sub-channels, sharing an intermediate frequency (IF), with each sub-channel undergoing independent DAC processing. The signals from multiple channels are then superimposed in the analog domain and transmitted through an RF antenna. However, these different hardware processing methods introduce errors between different sub-channels, such as phase offset (phase inconsistency), time offset, and power offset (power imbalance) at least one of these. Therefore, the above time-domain design can be applied to the frequency domain, as shown in Figure 7, to compensate for the error (such as phase error) between RSs (such as the first RS) at adjacent frequency domain positions, so as to better combine RSs (such as the first RS) at multiple frequency domain positions to obtain a higher precision time delay.

[0115] It should be noted that, Figures 4 to 7 The RS in the first RS can correspond to the first RS.

[0116] The consistency of the target characteristics of the first RS transmitted on different first time units within the first time window described in the embodiments of this application can also be expressed as follows: within the first time window, the first device is expected to maintain the consistency of the target characteristics between different first RS transmissions (requirement), or, within the first time window, the first RS transmitted on different first time units are transmitted using the same port.

[0120] The consistency of the target characteristics of the first RS transmitted on different first time units within the second frequency domain range described in this application embodiment can also be expressed as follows: within the second frequency domain range, the first device is expected to maintain consistency of the target characteristics between different first RS transmissions (requirement); or, within the second frequency domain range, the first RS transmitted on different first time units are transmitted using the same port. Optionally, in different second frequency domain ranges, the first device cannot (cannot) maintain consistency of the target characteristics of the first RS transmissions.

[0121] The phase of the first RS transmitted in the second frequency domain range described in this application embodiment is consistent, which can be understood as: the phase of the first RS transmitted in the second frequency domain range is the same, or the phase of the first RS transmitted in the second frequency domain range is continuous, or the phase change of the first RS transmitted in the second frequency domain range does not exceed a preset phase, or the phase change of the first RS transmitted in the second frequency domain range does not exceed a preset phase range or threshold.

[0123] The consistency of the delay of the first RS transmitted in the second frequency domain range described in the embodiments of this application can be understood as follows: the delay of the first RS transmitted in the second frequency domain range is the same, or the delay of the first RS transmitted in the second frequency domain range is continuous, or the delay variation of the first RS transmitted in the second frequency domain range does not exceed a preset delay, or the delay variation of the first RS transmitted in the second frequency domain range does not exceed a preset delay range or threshold.

[0124] Optionally, in addition to the phase, power, and delay described above, the target features in this application embodiment may also include, but are not limited to, features such as frequency, transmission beam, and radio frequency link.

[0125] Optionally, the consistency of the frequency of the first RS at different times or frequency domain locations can also be understood as: the consistency of frequency offset (such as carrier frequency offset or sampling frequency offset), or the frequency remains the same and the frequency change does not exceed a preset range or threshold; the consistency of the transmission beam can also be understood as: the transmission beam is the same; the consistency of the radio frequency link can also be understood as: the radio frequency link is the same, or no radio frequency link switching occurs.

[0126] In this embodiment, the first device transmits a first RS on at least two first time units; wherein the positions of the at least two first time units are determined based on at least one of the following: the position of available first time units, and the position of physical first time units. Specifically, the positions of at least two first time units are determined based on the positions of available first time units and / or physical first time units, thereby jointly estimating the measurement results using at least two first time units, improving the estimation performance of information such as Doppler, time, or angle. Furthermore, basing the positions of the at least two first time units on available first time units can reduce conflicts between the first RS transmission and other signals / channels, increasing (or not decreasing) the actual number of first RS transmissions, and improving the measurement result estimation performance.

[0127] Optionally, the first device determines the location of at least two first time units based on the location of available first time units or the location of physical first time units, which may be based on at least one of the following: instructions from other devices, protocol agreements, or the capabilities of the first device.

[0128] The embodiments of this application solve the problem of error (inconsistency in phase or power) when jointly estimating RS at different time domain or frequency domain locations, and improve the estimation accuracy of measurement results (such as Doppler, time delay, etc.) of joint estimation.

[0129] In this embodiment, the first device transmits the first RS on at least two first time units; wherein, the at least two first time units are located within at least one first time window, and the target features of the first RS transmitted on different first time units within the first time window are consistent, which can solve the problem of inconsistency in phase, power or time delay of the first RS caused by error when the first RS at different time domain positions is jointly estimated, and further improve the estimation performance of information such as Doppler, time or angle.

[0130] In this embodiment, the first device transmits a first RS on at least two first time units. The positions of the at least two first time units are determined based on at least one of the following: the position of an available first time unit, and the position of a physical first time unit. Furthermore, the at least two first time units are located within at least one first time window, and the target characteristics of the first RS transmitted on different first time units within the first time window are consistent. Specifically, determining the positions of at least two first time units based on the positions of available first time units and / or physical first time units improves the estimation performance of information such as Doppler, time, or angle. This allows the receiving device to improve the estimation performance of information such as Doppler, time, or angle by jointly estimating the reception status of the first RS on at least two first time units. Furthermore, the consistency of the target characteristics of the first RS transmitted on different first time units within the first time window solves the problem of inconsistencies in phase, power, or delay of the first RS caused by errors during joint estimation of first RS at different time-domain locations, further improving the estimation performance of information such as Doppler, time, or angle.

[0131] In this embodiment, the first device transmits the first RS in at least two second frequency domain ranges within the first frequency domain range; wherein, the second frequency domain ranges with adjacent frequency domain positions in the at least two second frequency domain ranges have overlapping frequency domain resources, the first RS transmitted in the at least two second frequency domain ranges are transmitted simultaneously in at least a portion of the second time units, and the target characteristics of the first RS transmitted in the second frequency domain ranges are consistent, which can solve the problem of inconsistency in the phase, power or time delay of the first RS caused by errors when the first RS at different frequency domain positions are jointly estimated, and further improve the estimation performance of information such as Doppler, time or angle.

[0132] In this embodiment, the first device transmits first information, which includes change information of target features of the first RS transmitted on at least two first time units. Based on the first information, at least one of the phase change information, power change information, and delay change information of the first RS transmitted on at least two first time units can be obtained. Then, it can be determined whether at least one of the phase, power, and delay of the first RS transmitted on at least two first time units is consistent. This can solve the problem that the phase, power, or delay of the first RS is inconsistent due to errors when the first RS at different time domain locations are jointly estimated, and further improve the estimation performance of information such as Doppler, time, or angle.

[0133] In this embodiment, the first device transmits first information, which includes change information of target features of the first RS transmitted within a first time window. Based on the first information, at least one of the phase change information, power change information, and delay change information of the first RS transmitted within the first time window can be obtained. This allows for determination of whether at least one of the phase, power, and delay of the first RS transmitted within the first time window is consistent. This solves the problem of inconsistency in the phase, power, or delay of the first RS caused by errors when jointly estimating the first RS at different time domain locations, and further improves the estimation performance of information such as Doppler, time, or angle.

[0134] In some embodiments, the available first time unit is a first time unit that is consistent with the transmission direction of the first RS, or the available first time unit is a flexible first time unit, or the available first time unit is a first time unit that does not conflict with the transmission of the first RS.

[0135] It should be noted that both uplink and downlink transmissions can be performed within the flexible first time unit.

[0136] In some embodiments, the first device may cancel the transmission of at least one first RS on a first time unit;

[0137] Wherein, the transmission of the first RS on at least one first time unit conflicts with the transmission of the first channel or signal, the priority of the first channel or signal is higher than the priority of the first RS, or the transmission direction of the first channel or signal is inconsistent with the transmission direction of the first RS.

[0138] Optionally, the first channel or signal can be a semi-static channel or signal. For example, the first channel or signal may be: SSB, or downlink channel / signal (if the first RS is uplink transmission (UL)), or uplink channel / signal (if the first RS is downlink transmission (DL)).

[0139] In some embodiments, the first RS is a reference signal for periodic or semi-persistent scheduling, and the first RS transmitted on at least two first time units corresponds to one or more periods.

[0140] In some embodiments, the first RS is an aperiodic reference signal, and the first RS transmitted on the at least two first time units corresponds to an aperiodic trigger.

[0141] In some embodiments, the first RS transmitted on at least two first time units can also be understood as: first RS burst, first RS instance, first RS occasion, etc., and the embodiments of this application do not limit this.

[0142] For example, at least two first RS transmitted on first time units correspond to a measurement result, which is used to perform specific operations (such as sensing, localization, channel estimation, channel state information determination, channel detection, etc.).

[0143] In some embodiments, the first RS transmitted on the at least two first time units corresponds to the same resource of the first RS, or the first RS transmitted on the at least two first time units corresponds to the resources of different first RSs. Alternatively, the first RS transmitted on the at least two first time units corresponds to the same transmission beam of the first RS, or the first RS transmitted on the at least two first time units corresponds to the transmission beam of different first RSs.

[0144] In some embodiments, the first RS transmitted on the at least two first time units is a repeated transmission of a first RS. This can optimize the repeated transmission of the first RS.

[0145] In some embodiments, the generation of the sequence of the first RS within each first time window is associated with an available first time unit. This includes associating the initial value of the PN sequence (cinit) with an available first time unit if the first RS is generated based on a PN sequence; and associating the sequence number (or group hop number or sequence hop number) of the ZC sequence with an available first time unit if the first RS is generated based on a ZC sequence. This increases the randomization of the sequence's temporal dimension. If the first time window spans multiple radio frames, it avoids repeatedly generating the sequence corresponding to the first RS, ensuring the autocorrelation or cross-correlation characteristics of the sequence's temporal dimension.

[0146] In some embodiments, the number of the at least two first time units is determined based on at least one of the following: indications from other devices, the capabilities of the first device, and protocol agreement information.

[0147] For example, the first device is a terminal, and the other devices are network-side devices. The network-side devices can indicate (directly or indirectly) the number of at least two first time units to the terminal.

[0148] For example, the first device is a terminal, which can determine the number of at least two first time units based on its capabilities, or the network-side device can determine the number of at least two first time units based on its capabilities.

[0149] In some embodiments, the interval between adjacent first time units in the at least two first time units is less than or equal to a first threshold. This can better maintain the consistency of at least one of the target characteristics such as phase, power, and delay of the first RS transmitted in the at least two first time units, or better maintain the consistency of at least one of the target characteristics such as phase, power, and delay of the first RS transmitted within the first time window.

[0150] Optionally, the first threshold may be agreed upon by a protocol, or the first threshold may be determined by a network-side device.

[0151] In some embodiments, the at least two first time units are distributed at equal intervals. The interval between the first time units can be the interval of physical first time units or the interval of available first time units.

[0152] Alternatively, in a case of equally spaced distribution, the first RS is transmitted through consecutive first time units. In this case, the first RS can be transmitted through consecutive physical first time units or available first time units. Specifically, if the first RS transmitted in a particular first time unit conflicts with other channels / signals, it can be postponed to the next available first time unit for transmission.

[0153] In some embodiments, the interval between consecutive first time units in the at least two first time units is determined based on the available first time units, or the interval between consecutive first time units in the at least two first time units is determined based on the physical first time units. Thus, the interval between consecutive first time units in the at least two first time units can be determined based on either the available first time units or the physical first time units.

[0154] It should be noted that the "interval between the first time units before and after" can also be referred to as or replaced by the "interval between adjacent first time units".

[0155] In some embodiments, the lengths of the first time windows in the at least one first time window are the same, or the lengths of the other first time windows in the at least one first time window are the same except for the last first time window.

[0156] In some embodiments, the length of each first time window in the at least one first time window is determined based on a physical first time unit. Thus, the length of each first time window can be determined based on a physical first time unit.

[0157] In some embodiments, the starting time-domain position of the first first time window in the at least one first time window is consistent with the starting time-domain position of the starting physical first time unit of the first RS. Therefore, the starting time-domain position of the first first time window in the at least one first time window can be determined based on the starting time-domain position of the starting physical first time unit of the first RS.

[0158] In some embodiments, the starting time-domain position of the first time window in the at least one first time window is consistent with the starting time-domain position of the first available first time unit of the first RS. Therefore, the starting time-domain position of the first time window in the at least one first time window can be determined based on the starting time-domain position of the first available first time unit of the first RS.

[0159] In some embodiments, the end-of-time field position of the last first time window in the at least one first time window coincides with the end-of-time field position of the last physical first time unit of the first RS. Therefore, the end-of-time field position of the last first time window in the at least one first time window can be determined based on the end-of-time field position of the last physical first time unit of the first RS.

[0160] In some embodiments, the end-of-time field position of the last first time window in the at least one first time window coincides with the end-of-time field position of the last available first time unit of the first RS. Therefore, the end-of-time field position of the last first time window in the at least one first time window can be determined based on the end-of-time field position of the last available first time unit of the first RS.

[0161] In some embodiments, the starting time-domain position of the first time window other than the first first time window in the at least one first time window is determined based on at least one of the following: the position of the physical first time unit, and the position of the available first time unit. Thus, the starting time-domain position of the first time window other than the first first time window in the at least one first time window can be determined based on the position of the physical first time unit and / or the position of the available first time unit.

[0162] In some embodiments, the first time unit corresponding to the end domain position of the first time window (excluding the last first time window) within the at least one first time window is determined based on at least one of the following: the length of each first time window, and the start time domain position of each first time window. Thus, the first time unit corresponding to the end domain position of the first time window (excluding the last first time window) within the at least one first time window can be determined based on the length of each first time window and / or the start time domain position of each first time window.

[0163] Optionally, if the first time unit corresponding to the end time domain position of a first time window, determined based on the length of each first time window and / or the start time domain position of each first time window, is an unavailable first time unit, then the first time unit corresponding to the end time domain position of the first time window is the nearest available first time unit before the determined unavailable first time unit. This ensures that the first time unit corresponding to the end time domain position of the first time window is an available first time unit.

[0164] Optionally, if the first time unit corresponding to the end domain position of a first time window, determined based on the length of each first time window and / or the start time domain position of each first time window, does not include the first RS, then the first time unit corresponding to the end domain position of the first time window is the nearest available first time unit that includes the first RS before the determined first time unit that does not include the first RS. This ensures that the first time unit corresponding to the end domain position of the first time window is an available first time unit that includes the first RS.

[0165] In some embodiments, if two adjacent first time windows in the at least one first time window do not overlap, the starting time domain position of the later first time window is the starting time domain position of the first physical first time unit after the ending time domain position of the previous first time window, or the starting time domain position of the later first time window is the starting time domain position of the first available first time unit after the ending time domain position of the previous first time window, or the starting time domain position of the later first time window is the starting time domain position of the first physical first time unit containing the first RS after the ending time domain position of the previous first time window, or the starting time domain position of the later first time window is the starting time domain position of the first available first time unit containing the first RS after the ending time domain position of the previous first time window.

[0166] For example, if two adjacent first time windows in at least one first time window do not overlap, the starting time domain position of the later first time window is the starting time domain position of the first physical first time unit after the ending time domain position of the previous first time window. Taking the first time window as the configured time window and the first time unit as the time slot as an example, the transmission of the first RS on 20 time slots is as follows: Figure 8 As shown, the starting time domain position of the configured time window is determined based on the physical time slot position (also known as the physical time slot count). It should be noted that... Figure 8 The RS in the first RS can correspond to the first RS.

[0167] For example, if two adjacent first time windows in at least one first time window do not overlap, the starting time domain position of the later first time window is the starting time domain position of the first available first time unit after the ending time domain position of the previous first time window. Taking the first time window as the configured time window and the first time unit as the time slot as an example, the transmission of RS (i.e., the first RS) on 10 time slots is as follows: Figure 9 As shown, the starting time domain position of the configured time window is determined based on the available time slot positions (also known as the available time slot count). It should be noted that... Figure 9 The RS in the first RS can correspond to the first RS.

[0168] In some embodiments, if two adjacent first time windows overlap in the at least one first time window, the starting time domain position of the latter first time window is Z third time units earlier than the ending time domain position of the former first time window; or, if two adjacent first time windows overlap in the at least one first time window, and the former first time window includes X consecutive available first time units (or X consecutive available first time units including the first RS) before its end and Y consecutive available first time units (or Y consecutive available first time units including the first RS) after its end, the starting time domain position of the latter first time window is Z third time units earlier than the ending time domain position of the former first time window; wherein X, Y, and Z are all positive integers.

[0169] For example, at least two adjacent first time windows overlap. Taking the first time window as the configured time window as an example, four configured time windows can be configured as follows: Figure 10 As shown. It should be noted that, Figure 10 The RS in the first RS can correspond to the first RS.

[0170] For example, at least one first time window may have partial overlap between two adjacent first time windows. Taking the first time window as an example, three configured time windows can be configured as follows: Figure 11 As shown. It should be noted that, Figure 11 The RS in the first RS can correspond to the first RS.

[0171] The third time unit described in this application embodiment can be one of the following:

[0172] Symbol, time slot, micro-time slot, subframe, frame, microsecond, millisecond, second.

[0173] It should be noted that the third time unit may be the same as or different from the first or second time unit, and this application embodiment does not limit this. For example, the first or second time unit is a slot, and the third time unit is a symbol.

[0174] In some embodiments, if two adjacent first time windows overlap in the at least one first time window, the overlapping time domain resources are greater than or equal to a second threshold, and / or, the overlapping time domain resources are less than or equal to a third threshold, and / or, the overlapping first time windows are determined based on indications from other devices, and / or, the overlapping time domain resources are determined based on at least one of the following: indications from other devices, the capabilities of the first device, and protocol agreement information.

[0175] Optionally, the second threshold is agreed upon by the protocol, or the second threshold is configured by the network side.

[0176] Optionally, the third threshold is agreed upon by the protocol, or the third threshold is configured by the network side.

[0177] Optionally, the second threshold and / or the third threshold may be determined based on the terminal's capabilities.

[0178] For example, the first RS of different first time windows in the overlapping portion can correspond to the same port or port index; or, the first RS of different first time windows in the overlapping portion can correspond to different ports or port indices.

[0179] For example, within the same first time window, the first RS corresponds to the same port or port index, or the first RS corresponds to the same port or port index; or, within the same first time window, the overlapping first RS and the non-overlapping first RS correspond to the same port or port index; or, within the same first time window, the overlapping first RS and the non-overlapping first RS correspond to different ports or port indices.

[0180] For example, adjacent first time windows are associated with different ports or port indices.

[0181] For example, adjacent (or consecutive) first time windows can also be associated with the same port or port index. For instance, phase changes occurring at the same port can be estimated using the same ports between adjacent first windows. Optionally, even if adjacent first time windows have the same port or port index, the assumptions for the first RS of the same port within different first windows may differ (e.g., inconsistencies in phase, etc.).

[0182] In some embodiments, whether there are overlapping first time windows in the at least one first time window is determined based on at least one of the following: indications from other devices, the capabilities of the first device, and protocol agreement information.

[0183] For example, other devices indicate at least one index of a first time window, the end domain position of which is indicated has a time range that overlaps with the time range of the next first time window; or, the start time domain position of which is indicated has a time range that overlaps with the time range of the previous first time window.

[0184] In some embodiments, the overlap range of the overlapping first time windows in the at least one first time window is determined based on at least one of the following: indications from other devices, the capabilities of the first device, and protocol agreement information.

[0185] It should be noted that the overlap of two first time windows can be understood as the partial or complete overlap of the temporal resources of the two first time windows. Non-overlapping first time windows can include: all first time windows having non-overlapping temporal resources, or some first time windows not overlapping with other first time windows, or the starting positions of some first time windows not overlapping with other first time windows.

[0186] In some embodiments, the at least one first time window is a configured time window, wherein each configured time window includes at least one sub-time window, the sub-time window being the time window for actually transmitting the first RS. Thus, at least one first time window can be determined based on the configured time window.

[0187] It should be noted that a sub-time window can also be called an actual window. Within a sub-time window, the first device is expected to maintain consistency in target characteristics such as phase, and / or power, and / or delay.

[0188] In some embodiments, the at least one first time window is a sub-time window within at least one configured time window, wherein each configured time window includes at least one sub-time window, which is the time window for the actual transmission of the first RS. Thus, at least one first time window can be determined based on the sub-time windows within the configured time window.

[0189] It should be noted that the configured time window can be understood as the nominal time window.

[0190] Optionally, the configured time window can be determined based on at least one of the time window configurations provided by other devices (such as time window length) and the time domain location of the first RS.

[0191] It should be noted that within the configured time window, some events may disrupt the consistency of target characteristics such as phase, power, and / or delay between the first RSs. The first device can only maintain the consistency of target characteristics such as phase, power, and / or delay within a shorter time range. Therefore, the first RSs within the shorter time range constitute a sub-time window.

[0192] In some embodiments, the at least one configured time window includes a first configured time window;

[0193] Wherein, the starting time domain position of the first sub-time window in the first configured time window is the first fourth time unit available for the first RS transmission on the first available first time unit within the first configured time window, and / or, the starting time domain position of a sub-time window other than the first sub-time window in the first configured time window is the first fourth time unit available for the first RS transmission after the target event occurs.

[0194] And / or,

[0195] The end-of-time field position of the last sub-time window in the first configured time window is the last fourth time unit available for the first RS transmission on the last available first time unit within the first configured time window, and / or, the end-of-time field position of a sub-time window in the first configured time window is the last fourth time unit available for the first RS transmission before the target event.

[0196] Wherein, after the occurrence of the target event, the target features of the first RS transmitted on at least two first time units are not consistent, or the target features of the first RS transmitted on different first time units within the first time window are not consistent.

[0197] Optionally, the target event disrupts the consistency of at least one of the target characteristics such as phase, power, and delay of the first RS transmitted on different first time units within the first time window; or, after the target event occurs, at least one of the target characteristics such as phase, power, and delay of the first RS transmitted on different first time units within the first time window is not consistent.

[0198] It should be noted that the first configuration time window can be any one of the at least one configuration time window, and this application embodiment does not limit this.

[0199] For example, taking the first time window as a sub-time window (also called the actual time window) within the configured time window, the transmission of 20 time slots of RS can be as follows: Figure 12 As shown. It should be noted that, Figure 12 The RS in the first RS can correspond to the first RS.

[0200] For example, taking the first time window as a sub-time window (also called the actual time window) within the configured time window, in the event of the target event, the transmission of RS in 20 time slots can be as follows: Figure 13 As shown. It should be noted that, Figure 13 The RS in the first RS can correspond to the first RS.

[0201] In some embodiments, if the target event occurs within the first configured time window, there is no fourth time unit available for the first RS transmission after the target event, or the first device is not configured to restart the first time window after the target event, or the capability of the first device does not support restarting the first time window after the target event, and there is no sub-time window within the first configured time window after the target event.

[0202] In some embodiments, the target event is a dynamic event or a semi-static event. For example, a dynamic event is an event triggered by Downlink Control Information (DCI) or Media Access Control Control Element (MAC CE); a semi-static event is an event not triggered by DCI or MAC CE.

[0203] Specifically, if a semi-static event occurs in the first configured time window, the first device forcibly restarts the first time window; and / or, if a dynamic event occurs in the first configured time window, the first device does not restart the first time window, or the first device determines whether to restart the first time window based on at least one of the following: the capabilities of the first device, or instructions from other devices.

[0204] The fourth time unit described in this application embodiment can be one of the following:

[0205] Symbol, time slot, micro-time slot, subframe, frame, microsecond, millisecond, second.

[0206] It should be noted that the fourth time unit may be the same as or different from the first, second or third time unit, and the embodiments of this application do not limit this.

[0207] In some embodiments, the target event includes at least one of the following: a first event and a second event;

[0208] Wherein, the first event is an event triggered by a device other than the first device, and the second event is an event triggered by the first device.

[0209] In one implementation, taking another device as a network-side device as an example, the first event can be determined according to the indication / configuration of the network-side device (or other devices). For example, based on the network-side configuration, the first device determines the uplink and downlink slot format, and further determines that there are other signals / channels transmitted in a different direction than the first RS transmission between consecutive first RS transmissions, resulting in the destruction of phase and other consistency. Specifically, the first event is visible to both the network-side device and the first device, or in other words, the network-side device and the first device have the same understanding of the first event.

[0210] In one implementation, during multiple first RS transmissions, a change in the antenna panel occurs between consecutive first RS transmissions, resulting in changes in information such as phase. The change in the antenna panel is determined autonomously by the first device and is not visible to other devices (such as network-side devices). Optionally, the first device can report relevant information about the second event to other devices.

[0211] Optionally, the relevant information of the first event may be agreed upon by the protocol, or the relevant information of the first event may be configured by the network side; and / or, the relevant information of the second event may be agreed upon by the protocol, or the relevant information of the second event may be configured by the network side.

[0212] Optionally, the sub-time windows in the configured time window are determined based on at least one of the first event and the second event.

[0213] In one implementation, the sub-time windows in the configured time window are determined only based on the first event. That is, after the first event occurs, there is no need for the first device to interact with other devices (such as network devices). Since the first event is controlled by other devices and is known to other devices, the other devices can automatically obtain relevant information about the first event from the first device and further determine the sub-time windows in the configured time window.

[0214] Optionally, the characteristics of the first or second event can be implicitly represented, without explicitly grouping or distinguishing the events.

[0215] In some embodiments, the first event includes, but is not limited to, at least one of the following:

[0216] In at least two of the first RS transmissions, there is a transmission of a signal or channel with a different direction than the first RS transmission between consecutive first RS transmissions; for example, the slot format is determined based on the 'tdd-UL-DL-ConfigurationCommon' or 'tdd-UL-DL-ConfigurationDedicated' configured by Radio Resource Control (RRC), and other signals / channels with different transmission directions are further determined.

[0217] In at least two of the first RS transmissions, the interval between two consecutive first RS transmissions is greater than or equal to a fourth threshold.

[0218] In at least two of the first RS transmissions, other signals or channels in the same direction as the first RS transmission are transmitted between the two consecutive first RS transmissions;

[0219] In at least two of the first RS transmissions, at least a portion of the first RS transmissions were canceled or discarded;

[0220] In at least two of the first RS transmissions, the spatial relation, transmission state (TCI state), or transmission beam (Tx beam) associated with the consecutive first RS transmissions changed;

[0221] In at least two of the first RS transmissions, the power control parameters or transmission power associated with the consecutive first RS transmissions changed;

[0222] In at least two of the first RS transmissions, at least one of the bandwidth or frequency domain position associated with the consecutive first RS transmissions changes; for example, frequency hopping occurs in the two consecutive first RS transmissions, resulting in different frequency domain positions.

[0223] In at least two of the first RS transmissions, the precoding information associated with the consecutive first RS transmissions has changed; for example, two consecutive first RS transmissions are non-codebook SRS transmissions and are associated with different precoding information.

[0224] In at least two first RS transmissions, consecutive first RS transmissions are associated with different resources of the first RS, or consecutive first RS transmissions are associated with different resource sets of the first RS, or consecutive first RS transmissions are associated with different Transmission Reception Points (TRPs).

[0225] In at least two of the first RS transmissions, the transmission timing (Tx timing) changed, and the change in transmission timing was determined based on a Timing Advance (TA) command;

[0226] In at least two of the first RS transmissions, the timing error group (TEG) associated with the consecutive first RS transmissions changed, or the phase error group (PEG) associated with the consecutive first RS transmissions changed, or the doppler error group (DEG) associated with the consecutive first RS transmissions changed.

[0227] In at least two of the first RS transmissions, the transmit antenna associated with the consecutive first RS transmissions changed, or the port associated with the consecutive first RS transmissions changed, or the antenna panel associated with the consecutive first RS transmissions changed, or the antenna reference point associated with the consecutive first RS transmissions changed, or the RF chain associated with the consecutive first RS transmissions changed.

[0228] In at least two of the first RS transmissions, the frequency offset changed.

[0229] Optionally, the fourth threshold may be agreed upon by the protocol, or the fourth threshold may be configured by the network side.

[0230] In some embodiments, the second event includes, but is not limited to, at least one of the following:

[0231] In at least two of the first RS transmissions, the time error group associated with the consecutive first RS transmissions changed, or the phase error group associated with the consecutive first RS transmissions changed, or the Doppler error group associated with the consecutive first RS transmissions changed.

[0232] In at least two of the first RS transmissions, the transmit antenna associated with the consecutive first RS transmissions changed, or the port associated with the consecutive first RS transmissions changed, or the antenna panel associated with the consecutive first RS transmissions changed, or the antenna reference point associated with the consecutive first RS transmissions changed, or the radio frequency link associated with the consecutive first RS transmissions changed.

[0233] In at least two of the first RS transmissions, the frequency offset changed, or the change in frequency offset was greater than or equal to the fifth threshold.

[0234] In at least two of the first RS transmissions, the transmission timing changed, and the change in transmission timing was determined by the first device.

[0235] Optionally, the fifth threshold may be agreed upon by the protocol, or the fifth threshold may be configured by the network side.

[0236] In some embodiments, the wireless communication method 200 further includes:

[0237] If the first event and the second event occur within the first time window, and the time of the first event overlaps with the time of the second event, the first device ignores sending the first information, or the first device does not send the first information.

[0238] In this embodiment, if a first event and a second event occur within the first time window, and the time of the first event overlaps with the time of the second event, it can be understood that the resulting inconsistency in at least one of the phase, power, and delay of the subsequent first RS has the same effect, and the first device does not need to report the first information.

[0239] In some embodiments, the transmission of first information by the first device can be combined with a first time window. This can be understood as follows: the first information represents changes or consistency information of target characteristics such as phase, power, and delay of the first RS within the first time window. The receiving device can initially determine the changes or consistency information of target characteristics such as phase, power, and delay of the first RS based on the first time window (e.g., changes or consistency information of target characteristics such as phase, power, and delay of the first RS between first time windows), and then determine the complete target characteristic or consistency information (e.g., changes or consistency information of target characteristics such as phase, power, and delay of the first RS within the first time window) based on the first information transmitted by the first device. Optionally, the first time window can be determined based on a first event, and the first information can be determined based on a second event. Optionally, the first time window is a configured (or nominal) time window or an actual time window. Optionally, if the change of the target characteristics of the first RS occurs within the first time window (configured or actual time window), then the first information needs to be reported; or, if the change of the target characteristics occurs between the first time windows, then no reporting is required.

[0240] In some embodiments, the transmission of first information by the first device may be decoupled from the first time window, or may not be limited to the first time window. This can be understood as follows: the first device, by transmitting first information, represents changes or consistency information of target characteristics such as phase, power, and delay during the transmission of the first RS, thereby enabling the receiving device to determine the consistency information of at least one of the target characteristics such as phase, power, and delay of the first RS, reducing estimation errors and improving estimation performance.

[0241] In some embodiments, the phase change information in the first information is determined based on a target event, and / or, the power change information in the first information is determined based on a target event, and / or, the delay change information in the first information is determined based on a target event; wherein the target event disrupts the consistency of at least one of the target characteristics such as phase, power, and delay of the first RS transmitted on different first time units within the first time window.

[0242] In some embodiments, the change information of the target feature in the first information includes, but is not limited to, at least one of the following:

[0243] Whether an event causing inconsistency in target features has occurred, information about the event causing inconsistency in target features, timestamp of the first RS that caused inconsistency in target features, timestamp of the first RS group that caused inconsistency in target features, target feature error group associated with the first RS that caused inconsistency in target features, identifier of the target feature error group associated with the first RS that caused inconsistency in target features, at least one of the target feature error mean, target feature error variance, and target feature error range associated with the target feature error group associated with the first RS that caused inconsistency in target features, timestamp of the event that caused inconsistency in target features, whether the first time window was restarted after the event that caused inconsistency in target features occurred, phase difference before and after the event that caused inconsistency in target features, at least one of the target feature difference mean, variance, distribution type, and range before and after the event that caused inconsistency in target features.

[0244] In some embodiments, the change information of the target feature in the first information is represented by the sequence change information corresponding to the transmission of the first RS, or the change information of the target feature in the first information is represented by the pattern change information corresponding to the first RS.

[0245] In some embodiments, the phase change information in the first information includes, but is not limited to, at least one of the following:

[0246] Whether an event causing phase inconsistency occurred, information about the event causing phase inconsistency, the timestamp of the first RS that caused phase inconsistency, the timestamp corresponding to the first RS group that caused phase inconsistency, the phase error group associated with the first RS that caused phase inconsistency, the identifier of the phase error group associated with the first RS that caused phase inconsistency, at least one of the phase error mean, phase error variance, and phase error range corresponding to the phase error group associated with the first RS that caused phase inconsistency, the timestamp of the event that caused phase inconsistency, whether the first time window was restarted after the event that caused phase inconsistency occurred, the phase difference before and after the event that caused phase inconsistency occurred, and at least one of the phase difference before and after the event that caused phase inconsistency occurred, including the mean, variance, distribution type, and range.

[0247] For example, the timestamp of the first RS where phase inconsistency occurs, such as when the event causing the phase inconsistency occurs before the first RS, resulting in phase inconsistency in subsequent first RSs, is reported as the timestamp of the first RS most recent after the event. Optionally, the first RS before this timestamp may have a phase inconsistency with the first RS of this timestamp.

[0248] The first RS group described in the embodiments of this application may correspond to the first RS burst or the first RS instance.

[0249] Optionally, the phase change information in the first information can be represented by the sequence change information corresponding to the transmission of the first RS, or the phase change information in the first information can be represented by the pattern change information corresponding to the first RS. Specifically, the phase change information in the first information can be implicitly reflected by the sequence change information corresponding to the transmission of the first RS, or the phase change information in the first information can be implicitly reflected by the pattern change information corresponding to the first RS.

[0250] Optionally, if the first time window is a configured time window, the information causing the phase change is limited to the phase change within the configured time window, or the information causing the phase change is limited to the phase change within the sub-time windows of the configured time window.

[0251] Optionally, if the first time window is a configured time window, the information causing phase changes is limited to phase changes within the configured time window. This can be understood as follows: if the phase change occurs between the configured time windows, it does not need to be reported; if the phase change occurs within the configured time window, it needs to be reported.

[0252] Optionally, if the first time window is a sub-time window within the configured time window, the information causing the phase change is limited to the phase change within the sub-time window of the configured time window. This can be understood as follows: if the phase change occurs between sub-time windows within the configured time window, no reporting is required; if the phase change occurs within a sub-time window within the configured time window, reporting is required.

[0253] In some embodiments, some events (such as the second event) are initiated by the first device. If the first device (such as the UE) and the receiving device (such as the network-side device) cannot be aligned in advance, the first device needs to report event information, phase discontinuity information, or first time window restart information, such as phase change information in the first information, to assist the receiving device in processing the first RS and avoid processing the first RS with inconsistent phases together.

[0254] In some embodiments, the first RS sent by the first device is received not only by the TRP of the serving cell but also by the TRP of the neighboring cell. If a first event initiated by the serving TRP causes a phase change, the serving cell needs to notify the neighboring cell TRP every time a dynamic event (such as the first event) occurs. However, by reflecting the phase change through the change in the sequence of the first RS, the neighboring cell TRP only needs to detect the first RS to determine the phase change, reducing the signaling overhead of the serving TRP notifying the neighboring cell of the phase change.

[0255] In some embodiments, the power change information in the first information includes, but is not limited to, at least one of the following:

[0256] Whether an event causing power inconsistency occurred, information about the event causing power inconsistency, the timestamp of the first RS that caused power inconsistency, the timestamp corresponding to the first RS group that caused power inconsistency, the power error group associated with the first RS that caused power inconsistency, the identifier of the power error group associated with the first RS that caused power inconsistency, at least one of the power error mean, power error variance, and power error range corresponding to the power error group associated with the first RS that caused power inconsistency, the timestamp of the event that caused power inconsistency, whether the first time window was restarted after the event that caused power inconsistency occurred, the power difference before and after the event that caused power inconsistency occurred, and at least one of the mean, variance, distribution type, and range of the power difference before and after the event that caused power inconsistency occurred.

[0257] For example, the timestamp of the first RS where the power inconsistency occurs, such as when the event causing the power inconsistency occurred before the first RS, resulting in power inconsistency in subsequent first RSs, is reported as the timestamp of the first RS most recent after the event. Optionally, the power of the first RS before this timestamp may be inconsistent with the power of the first RS at this timestamp.

[0258] Optionally, the power change information in the first information can be represented by the sequence change information corresponding to the transmission of the first RS, or the power change information in the first information can be represented by the pattern change information corresponding to the first RS. Specifically, the power change information in the first information can be implicitly reflected by the sequence change information corresponding to the transmission of the first RS, or the power change information in the first information can be implicitly reflected by the pattern change information corresponding to the first RS.

[0259] Optionally, if the first time window is a configured time window, the information causing the power change is limited to the power change within the configured time window, or the information causing the power change is limited to the power change within a sub-time window of the configured time window.

[0260] Optionally, if the first time window is the configured time window, the information causing the power change is limited to the power change within the configured time window. This can be understood as follows: if the power change occurs between the configured time windows, it does not need to be reported; if the power change occurs within the configured time window, it needs to be reported.

[0261] Optionally, if the first time window is a sub-time window within the configured time window, the information causing the power change is limited to the power change within the sub-time window of the configured time window. This can be understood as follows: if the power change occurs between sub-time windows within the configured time window, no reporting is required; if the power change occurs within a sub-time window within the configured time window, reporting is required.

[0262] In some embodiments, some events (such as the second event) are initiated by the first device. If the first device (such as the UE) and the receiving device (such as the network-side device) cannot be aligned in advance, the first device needs to report event information, phase discontinuity information, or first time window restart information, such as power change information in the first information, to assist the receiving device in processing the first RS and avoid processing the first RS with inconsistent power together.

[0263] In some embodiments, the first RS sent by the first device is received not only by the TRP of the serving cell but also by the TRP of the neighboring cell. If a first event initiated by the serving TRP causes a power change, the serving cell needs to notify the neighboring cell TRP every time a dynamic event (such as the first event) occurs. However, by reflecting the power change through the change in the sequence of first RS, the neighboring cell TRP only needs to detect the first RS to determine the power change, reducing the signaling overhead of the serving TRP notifying the neighboring cell of the power change.

[0264] In some embodiments, the time delay change information in the first information includes, but is not limited to, at least one of the following:

[0265] Whether an event causing delay inconsistency occurred, information about the event causing delay inconsistency, the timestamp of the first RS that caused delay inconsistency, the timestamp corresponding to the first RS group that caused delay inconsistency, the delay error group associated with the first RS that caused delay inconsistency, the identifier of the delay error group associated with the first RS that caused delay inconsistency, at least one of the following: mean delay error, variance delay error, and range delay error corresponding to the delay error group associated with the first RS that caused delay inconsistency, the timestamp of the event that caused delay inconsistency, whether the first time window was restarted after the event that caused delay inconsistency occurred, the delay difference before and after the event that caused delay inconsistency occurred, and at least one of the following: mean, variance, distribution type, and range of the delay difference before and after the event that caused delay inconsistency occurred.

[0266] For example, the timestamp of the first RS where a delay inconsistency occurs, such as when the event causing the delay inconsistency occurred before the first RS, resulting in a delay inconsistency for subsequent first RSs, is reported as the timestamp of the first RS most recent after the event. Optionally, the delay of the first RS before this timestamp may be inconsistent with the delay of the first RS with this timestamp.

[0267] Optionally, the time delay variation information in the first information can be represented by the sequence variation information corresponding to the transmission of the first RS, or the time delay variation information in the first information can be represented by the pattern variation information corresponding to the first RS. Specifically, the time delay variation information in the first information can be implicitly reflected by the sequence variation information corresponding to the transmission of the first RS, or the time delay variation information in the first information can be implicitly reflected by the pattern variation information corresponding to the first RS.

[0268] Optionally, if the first time window is a configured time window, the information causing the delay change is limited to the delay change within the configured time window, or the information causing the delay change is limited to the delay change within the sub-time windows of the configured time window.

[0269] Optionally, if the first time window is a configured time window, the information causing latency changes is limited to latency changes within the configured time window. This can be understood as follows: if the latency change occurs between the configured time windows, no reporting is required; if the latency change occurs within the configured time window, reporting is required.

[0270] Optionally, if the first time window is a sub-time window within the configured time window, the information causing latency changes is limited to latency changes within the sub-time windows within the configured time window. This can be understood as follows: if the latency change occurs between sub-time windows within the configured time window, no reporting is required; if the latency change occurs within a sub-time window within the configured time window, reporting is required.

[0271] In some embodiments, some events (such as the second event) are initiated by the first device. If the first device (such as the UE) and the receiving device (such as the network-side device) cannot be aligned in advance, the first device needs to report event information, phase discontinuity information, or first time window restart information, such as the delay change information in the first information, to assist the receiving device in processing the first RS and avoid processing the first RS with inconsistent delays together.

[0272] In some embodiments, the first RS sent by the first device is received not only by the TRP of the serving cell but also by the TRP of the neighboring cell. If a first event initiated by the serving TRP causes a delay change, the serving cell needs to notify the neighboring cell TRP every time a dynamic event (such as the first event) occurs. However, by reflecting the delay change through the change in the sequence of the first RS, the neighboring cell TRP only needs to detect the first RS to determine the delay change, reducing the signaling overhead of the serving TRP notifying the neighboring cell of the delay change.

[0273] In some embodiments, the phase change information in the first information may be represented by sequence change information or pattern change information based on the agreement, instructions from other devices, or the capabilities of the first device; or, the power change information in the first information may be represented by sequence change information or pattern change information based on the agreement, instructions from other devices, or the capabilities of the first device; or, the delay change information in the first information may be represented by sequence change information or pattern change information based on the agreement, instructions from other devices, or the capabilities of the first device.

[0274] In some embodiments, the sequence variation information includes, but is not limited to, at least one of the following:

[0275] Cyclic shift changes, cinit changes in sequence association, sequence changes within a sequence group, sequence group changes, and base sequence changes in sequence association.

[0276] Optionally, the cyclic shift change can be a cyclic shift hopping. Multiple (e.g., 2) cyclic shifts in the cyclic shift group of the first device perform cyclic shift hopping, which can be understood as performing cyclic shift hopping.

[0277] One implementation: According to at least one method agreed upon by a protocol or instructed by other devices or determined by the first device, the first device determines two cyclic shifts and / or an initial default cyclic shift, such as cyclic shift 0, contained in the cyclic shift group. If a phase change occurs in the first RS, the cyclic shift associated with the first RS becomes cyclic shift 1; if a subsequent phase change occurs in the first RS, the cyclic shift associated with the first RS becomes cyclic shift 0; and so on, switching between the two cyclic shifts. Alternatively, the cyclic shift(s) contained in the cyclic shift group may have different cyclic shifts corresponding to the two RSs before and after a phase change.

[0278] One implementation adds a 'specific field' to the initial value (cinit) of the sequence association, where the 'specific field' is 1 bit, and the change of the initial value (cinit) of the sequence association is reflected by '0' or '1' in the 'specific field'.

[0279] It should be noted that sequence changes within a sequence group can be understood as sequence hopping, that is, sequence hopping within a sequence group.

[0280] It should be noted that sequence group changes can be understood as sequence group hopping, that is, frequency hopping between sequence groups.

[0281] It should be noted that the base sequence changes for sequence association can be TD-OCC, FD-OCC, or TD-FD-OCChopping. Optionally, the sequence changes can be represented by jumps in the index of an orthogonal cover code (OCC).

[0282] In some embodiments, the pattern change information includes, but is not limited to, at least one of the following:

[0283] Changes in comb offset lead to changes in the position of the OFDM symbol.

[0284] Optionally, a change in comb offset can be understood as comb offsethopping within a comb offset group.

[0285] Optionally, OFDM symbol changes can be understood as OFDM symbol position hopping within an OFDM symbol position group.

[0286] Optionally, the change in the OFDM symbol position can be understood as the change in the OFDM symbol position of the first RS within a slot, such as the change in the initial OFDM symbol position.

[0287] In some embodiments, the changes in the sequence change information and / or the pattern change information may be limited to changes between two sequences or two patterns, and / or the scope of the sequence change information and / or the pattern change information may be: within a configured window, within an actual window, or during the first RS transmission of multiple first time units; and / or, in the event of a 'second event'.

[0288] In some embodiments, whether to enable the transmission of the corresponding sequence change information or the corresponding pattern change information of the first RS to represent the phase change information in the first information can be determined based on instructions from other devices, protocol agreements, or the capabilities of the first device; or, whether to enable the transmission of the corresponding sequence change information or the corresponding pattern change information of the first RS to represent the power change information in the first information can be determined based on instructions from other devices, protocol agreements, or the capabilities of the first device; or, whether to enable the transmission of the corresponding sequence change information or the corresponding pattern change information of the first RS to represent the delay change information in the first information can be determined based on instructions from other devices, protocol agreements, or the capabilities of the first device.

[0289] In some embodiments, the first information is transmitted based on the target type;

[0290] The target type is one of the following:

[0291] Single-time reporting (or non-periodic reporting), periodic reporting (or semi-continuous reporting), and reporting triggered by a target event.

[0292] In some embodiments, if the target type is a single report, the first information is sent within a first duration after the first device receives the request; or, the first information is sent within a first duration after at least two transmissions of the first RS; or, the first information is sent within a first duration after the first time window.

[0293] In some embodiments, if the target type is periodic reporting, the first information is sent by the first device periodically. For example, the first device reports the phase change information of the first RS at a certain period. For each periodic report, the phase change information of the first RS within one period is reported. Optionally, if no RS phase change information appears within one period, then 'no change' is reported in this period, or no report is made in this period.

[0294] In some embodiments, if the target type is a target event-triggered report, the first information is sent by the first device within a second duration after the target event, or the first information is sent by the first device within a third duration after the first time window, or the first information is sent by the first device within a fourth duration after the first RS transmission in which the target characteristic changes. One implementation: If a phase inconsistency occurs in the first RS transmission, a corresponding report is initiated and information indicating a phase change is provided; or, if no phase change occurs, no corresponding report is initiated or the report indicates 'no change'. Another implementation: If a phase inconsistency occurs in the first RS transmission within the first time window, a report is initiated and information indicating a target characteristic change is provided; or, if no target characteristic inconsistency occurs in the first RS transmission within the first time window, no corresponding report is initiated. Optionally, the first time window can be determined based on the 'first event'. Optionally, the reporting initiation time can be one of the following: a period of time after the event occurs, a period of time after multiple first RS transmissions, or a period of time after the first RS transmission in which the target characteristic changes.

[0295] In some embodiments, before the first device transmits the first information, the wireless communication method 200 further includes: the first device transmitting second information;

[0296] The second information includes at least one of the following:

[0297] The first indication information is used to indicate the target type.

[0298] In this embodiment, before reporting the first information, the first device receives requests from other devices and reports the information according to the requests from the other devices.

[0299] For example, if the first device sends first information, the first device receives second information from other devices, such as the first device being a terminal and the other devices being network-side devices.

[0300] For example, if the first device sends the first information, the first device sends the second information to other devices, such as the first device being a network-side device and the other devices being terminals.

[0301] For example, if the first device receives the first information, the first device sends the second information to other devices, such as the first device being a network-side device and the other devices being terminals.

[0302] For example, if the first device receives the first information, the first device receives the second information from other devices, such as the first device being a terminal and the other devices being network-side devices.

[0303] In some embodiments, if the first indication information indicates a single report, the second information further includes second indication information, wherein the second indication information is used to indicate the feedback time for a single report. For example, the feedback time (or feedback time requirement, or feedback time offset), wherein the feedback time is relative to the requested feedback time.

[0304] In some embodiments, if the first indication information indicates periodic reporting, the second information further includes a third indication information, wherein the third indication information is used to indicate at least one of the following: a reporting period, and a start reporting time. For example, the feedback time (or feedback time requirement, or feedback time offset) of the first period, wherein the feedback time is relative to the requested feedback time, or SFN slot 0. For example, if the feedback time of the first period is determined according to the period, such as being the same as the period, then no special configuration is required.

[0305] In some embodiments, if the first indication information indicates that a target event triggers a report, the second information further includes a fourth indication information, wherein the fourth indication information is used to indicate at least one of the following: information about the target event, and the feedback time for the target event to trigger a report. For example, event information, such as information about a second event, and feedback time (or feedback time requirement), indicating that feedback and reporting are required within a certain feedback time after the event occurs.

[0306] In some embodiments, there are two overlapping first time windows in the at least one first time window;

[0307] Within overlapping time domain regions, the first RS transmitted in the preceding first time window and the first RS transmitted in the following first time window correspond to different ports or port indices; and / or,

[0308] Within overlapping time-domain regions, the first RS transmitted within the preceding first time window and the first RS transmitted within the following first time window occupy the same time-frequency resources and are distinguished by code division multiplexing (CDM); or, the first RS transmitted within the preceding first time window and the first RS transmitted within the following first time window occupy the same frequency-domain resources and are distinguished by time-division multiplexing (TDM); or, the first RS transmitted within the preceding first time window and the first RS transmitted within the following first time window occupy the same time-domain resources and are distinguished by frequency-division multiplexing (FDM); and / or,

[0310] Within overlapping time domain regions, the first RS transmitted in the preceding first time window and the first RS transmitted in the following first time window occupy the same time domain resources.

[0311] Within the overlapping time domain regions, the first RS transmitted in the preceding first time window and the first RS transmitted in the following first time window occupy the same frequency domain resources and different time domain resources. The transmission power of the first RS in the overlapping portion of the preceding first time window is the same as the transmission power of the first RS in the non-overlapping portion, and / or, the transmission power of the first RS in the overlapping portion of the following first time window is the same as the transmission power of the first RS in the non-overlapping portion; and / or,

[0312] Within overlapping time domain regions, the frequency domain positions of the first RS transmitted in the preceding first time window and the first RS transmitted in the following first time window are the same, and / or, the patterns of the first RS transmitted in the preceding first time window and the first RS transmitted in the following first time window are the same, and / or, the cyclic shifts associated with the sequence mapping of the first RS transmitted in the preceding first time window and the first RS transmitted in the following first time window are the same, and / or, the orthogonal codes associated with the sequence mapping of the first RS transmitted in the preceding first time window and the first RS transmitted in the following first time window are the same.

[0313] In some implementations, within overlapping time-domain regions, the first RS transmitted in the preceding first time window and the first RS transmitted in the following first time window occupy the same time-frequency resources and are distinguished by CDM. Here, the same time-frequency resources can be understood as at least one of the following: the same symbol(s) or the same RE(s) position. Specifically, CDM includes at least one of the following: different orthogonal sequence mappings, such as different ZC sequences, such as... Figure 14 As shown; different cyclic shifts of the same sequence, such as different cyclic shifts of the same ZC sequence, such as... Figure 15 As shown. The same sequence is multiplied by different orthogonal codes, such as time-domain orthogonal codes: TD-OCC codes, as shown in A of Figure 15; frequency-domain orthogonal codes: FD-OCC codes, as shown in B of Figure 15; and time-frequency orthogonal codes: TD-OCC+FD-OCC codes, as shown in C of Figure 15. It should be noted that... Figure 14 and Figure 15 RS1 and RS2 in the table can correspond to the first RS.

[0314] In some implementations, within overlapping time-domain regions, the first RS transmitted in the preceding first time window and the first RS transmitted in the following first time window occupy the same frequency-domain resources and are distinguished by TDM. Here, "same frequency-domain location" can be understood as at least one of: same subcarrier location, same frequency-domain density, and same frequency-domain range. Specifically, TDM includes at least one of the following: their respective first RSs are located in adjacent symbols, such as interleaved TDM, etc. Figure 16 As shown in A; the interval between the symbols of the first RS of each is less than or equal to a certain threshold, such as Figure 16 As shown in B in the diagram. It should be noted that... Figure 16 RS1 and RS2 in the table can correspond to the first RS.

[0315] In some implementations, within overlapping time-domain regions, the first RS transmitted in the preceding first time window and the first RS transmitted in the following first time window occupy the same time-domain resources and are distinguished by FDM. Here, "same time-domain resources" can be understood as: the same symbol. Specifically, FDM includes at least one of the following: their respective first RSs are located on adjacent subcarriers (or REs), such as interleaved FDM, etc. Figure 17 As shown in A; the spacing between the subcarriers of their respective first RSs is less than or equal to a certain threshold, such as... Figure 17 As shown in B in the diagram. It should be noted that... Figure 17 RS1 and RS2 in the table can correspond to the first RS.

[0316] In some embodiments, the at least one first time window contains two non-overlapping first time windows, and the temporal domain resources of the two first time windows are adjacent. The wireless communication method 200 further includes:

[0317] The first device transmits the second RS within the second time window;

[0318] Wherein, the density of the second RS is higher than that of the first RS, the starting time domain position of the second time window is the last P-th fifth time unit of the previous first time window, and the ending time domain position of the second time window is the Q-th fifth time unit of the next first time window, where P and Q are both positive integers.

[0319] In this embodiment, the RS design of the boundary of two adjacent non-overlapping first time windows is used to estimate the phase change between adjacent first time windows, so as to combine multiple first time windows to obtain a more accurate measurement result.

[0320] In this embodiment, the duration of the second time window consists of the last P-th fifth time unit of the first first time window and the first Q fifth time units of the second first time window.

[0321] Optionally, the second time window may not be explicitly displayed; the starting position of the second time window can be understood as the starting position of the second RS, and the ending position of the second time window can be understood as the ending position of the second RS.

[0322] In this embodiment, a second RS with a higher temporal density than the first RS is configured at the boundary of the two first time windows.

[0323] Optionally, the second RS of different symbols can have the same frequency domain position.

[0324] Optionally, the temporal density of the second RS is 1 (adjacent symbols) or 2 (spaced 2 symbols).

[0325] Optionally, the second RS can be the same as or different from the first RS. If they are the same, it can be understood as configuring the first RS with a higher time-domain density within the second time window; if they are different, it can be understood as configuring an independent RS within the second time window.

[0326] In one implementation, the second RS begins at the last P-th fifth time unit of the preceding first time window, and ends at the Q-th fifth time unit of the following first time window. The temporal density of the second RS is X. Taking the fifth time unit as a symbol as an example, such as... Figure 18 and Figure 19 As shown, the second RS starts at the last symbol of the previous first time window and ends at the first symbol of the next first time window, occupying two symbols; the time-domain density is 1, meaning it occupies consecutive symbols. It should be noted that... Figure 18 RS1 can correspond to the first RS, and RS2 can correspond to the second RS.

[0327] The fifth time unit described in this application embodiment can be one of the following:

[0328] Symbol, time slot, micro-time slot, subframe, frame, microsecond, millisecond, second.

[0329] It should be noted that the fifth time unit may be the same as or different from the first, second, third or fourth time unit, and the embodiments of this application do not limit this.

[0330] In some embodiments, the symbols at the boundaries of the first time window may have a higher density not only in the time domain but also in the frequency domain to ensure the accuracy of the estimation at the boundaries. For example, considering that some information from the symbol measurements at the boundaries of the first time window (such as phase change information) may not be coherently accumulated throughout the first time window, a higher signal-to-noise ratio (SNR) is required.

[0331] In some embodiments, there are two first time windows in the at least one first time window, and the first RS transmitted in the first first time window and the first RS transmitted in the second first time window correspond to different ports or port indices.

[0332] In some embodiments, within overlapping frequency domain regions, the first RS transmitted in the preceding second frequency domain region and the first RS transmitted in the following second frequency domain region occupy the same frequency domain resources and are distinguished by CDM; or, the first RS transmitted in the preceding second frequency domain region and the first RS transmitted in the following second frequency domain region occupy the same time domain resources and are distinguished by FDM; and / or,

[0333] The transmit power corresponding to the first RS transmitted on the resource element RE in the overlapping portion of the preceding second frequency domain is half the transmit power corresponding to the first RS transmitted on the RE in the non-overlapping portion, and / or, the transmit power corresponding to the first RS transmitted on the RE in the overlapping portion of the following second frequency domain is half the transmit power corresponding to the first RS transmitted on the RE in the non-overlapping portion; or, the transmit power corresponding to the first RS transmitted on the RE in the overlapping portion of the preceding second frequency domain is the same as the transmit power corresponding to the first RS transmitted on the RE in the non-overlapping portion, and / or, the transmit power corresponding to the first RS transmitted on the RE in the overlapping portion of the following second frequency domain is the same as the transmit power corresponding to the first RS transmitted on the RE in the non-overlapping portion; and / or,

[0334] Within overlapping frequency domain regions, the time domain positions of the first RS transmitted in the preceding second frequency domain range and the first RS transmitted in the following second frequency domain range are the same, and / or, the patterns of the first RS transmitted in the preceding second frequency domain range and the first RS transmitted in the following second frequency domain range are the same, and / or, the cyclic shifts associated with the sequence mapping of the first RS transmitted in the preceding second frequency domain range and the first RS transmitted in the following second frequency domain range are the same, and / or, the orthogonal codes associated with the sequence mapping of the first RS transmitted in the preceding second frequency domain range and the first RS transmitted in the following second frequency domain range are the same.

[0335] In some implementations, within overlapping frequency domain regions, the first RS transmitted in the preceding second frequency domain range and the first RS transmitted in the following second frequency domain range occupy the same frequency domain resources and are distinguished by CDM. Here, "the same frequency domain resources" can be understood as: the same RE(s) location. Specifically, such as... Figure 20As shown, CDM includes at least one of the following: different orthogonal sequence mappings, such as different ZC sequences; different cyclic shifts of the same sequence, such as different cyclic shifts of the same ZC sequence. Specifically, the same sequence is multiplied by different orthogonal codes, such as time-domain orthogonal codes: TD-OCC codes; frequency-domain orthogonal codes: FD-OCC codes; or time-frequency orthogonal codes: TD-OCC+FD-OCC codes. It should be noted that... Figure 20 RS1 and RS2 in the table can correspond to the first RS.

[0336] In some implementations, within overlapping frequency domain regions, the first RS transmitted in the preceding second frequency domain range and the first RS transmitted in the following second frequency domain range occupy the same time domain resources and are distinguished by FDM. Specifically, FDM includes at least one of the following: the respective first RSs are located on adjacent subcarriers (or REs), such as interleaved FDM, etc. Figure 21 As shown in A; the spacing between the subcarriers of their respective first RSs is less than or equal to a certain threshold, such as... Figure 21 As shown in B in the diagram.

[0337] It should be noted that, Figure 21 RS1 and RS2 in the table can correspond to the first RS.

[0338] The technical solution of this application is described in detail below through specific embodiments.

[0339] Example 1, taking the following scheme as an example: The first device transmits the first RS on at least two first time units, and the positions of the at least two first time units are determined based on at least one of the following: the position of the available first time unit (also referred to as available time unit counting) and the position of the physical first time unit (also referred to as physical time unit counting)).

[0340] Determine the positions of at least two first time units based on the position of the physical first time unit.

[0341] Option 1-1, FDD

[0342] Optionally, at least two first time units are consecutive first time units, such as consecutive time slots, and the first RS is transmitted N times consecutively, such as... Figure 22 As shown, N = 10. Wherein, Figure 22 The "U" in the text indicates uplink transmission.

[0343] Optionally, at least two first time units can be equally spaced, such as equally spaced time slots, with the first RS transmitting N consecutively at equal intervals. Taking a time slot as an example, for instance... Figure 23 As shown, N=5, the gap is 1 slot (or the slot offset is 2 slots). Figure 23 RS in the first RS corresponds to RS. Figure 23 The "U" in the text indicates uplink transmission.

[0344] Option 1-2, TDD

[0345] Optionally, at least two first time units can be consecutive, such as consecutive slots; or N consecutive transmissions. Taking a time slot as an example, for instance... Figure 24 As shown, N=20, Figure 24 The RS in the first time unit corresponds to the first RS. However, due to transmissions in other directions, such as downlink time slots or synchronization signal blocks (SSBs), which may conflict with the first RS at a specific first time unit, the first RS will be discarded or canceled. Therefore, the actual number of first time units transmitting the first RS can be less than the configured number of first time units N, for example... Figure 24 The actual number of first time units (slots) of the RS transmitted in the middle is 10.

[0346] Optionally, at least two first time units can be equally spaced, such as equally spaced time slots, with the first RS transmitting N consecutively at equal intervals. Taking a time slot as an example, for instance... Figure 25 As shown, N=10, and the interval is 11 slots (or the slot offset is 2 slots). Figure 25 The RS in the text corresponds to the first RS. However, due to the existence of downlink time slots or transmission in other directions such as SSB, the actual number of first time units (slots) of the first RS transmitted at equal intervals is 6.

[0347] The positions of at least two first time units are determined based on the positions of the available first time units.

[0348] Option 2-1, FDD

[0349] Optionally, for FDD, there are generally no signals or channels in other directions that affect the first RS transmission. Therefore, it is generally considered that the count of the available first time unit in FDD is equivalent to the count of the physical first time unit.

[0350] Option 2-2, TDD

[0351] Optionally, at least two first time units can be consecutive available first time units, such as consecutive slots; or N consecutive transmissions. First RS transmission on consecutive available first time units: If, in a specific first time unit, the first RS cannot be transmitted due to a conflict with other channels / signals, then that first time unit is skipped, and transmission is postponed to the next available first time unit. If, during the first RS transmission of at least two first time units, there is a conflict with a downlink channel / signal or SSB, then the transmission is skipped and postponed. Taking the first time unit as a time slot as an example, such as... Figure 26 As shown, N=10, Figure 26 The RS in the text corresponds to the first RS. Transmission of 10 consecutive available slots can be understood as transmission in 10 consecutive flexible or uplink time slots.

[0352] Optionally, at least two first time units are equally spaced first time units; and the transmission is carried out N times at equal intervals.

[0353] Equal-interval transmission method 1: The interval is counted according to the physical first time unit, but at least two first time units are counted for the available first time units of the first RS. That is, after determining the first first time unit of the first RS, the interval is determined according to the physical first time unit count, and the next first time unit of the next first RS is determined; if there is a conflict with other channels / signals on a specific first time unit, and the first RS cannot be transmitted, then that first time unit is skipped, and transmission is postponed to the next available first time unit. Taking the first time unit as a time slot as an example, such as... Figure 27 As shown, N=5, with an interval of 1 slot (or a slot offset of 2 slots); however, due to the counting of the first time unit of Available, the actual interval may be greater than 1 slot. Figure 27 RS in the table corresponds to the first RS.

[0354] Equal-interval transmission method 2: The interval is counted according to the available first time unit, and the available first time units are counted for the first RS with multiple first time units. That is, after determining the first first time unit of the first RS, the interval between the first time unit of the next first RS and the first time unit of the previous first RS is X available first time units. Taking the first time unit as a time slot as an example, such as... Figure 28 As shown, the number of time units in the first time unit is N=4, and the interval is 1 available slot (or the slot offset is 2 slots). Figure 28 RS in the table corresponds to the first RS.

[0355] Optionally, other channels / signals are semi-statically configured.

[0356] Optionally, when determining the time-domain location of the first RS during transmission in at least two first time units, the available or physical count of the first device may be indicated or agreed upon by other devices (such as network devices).

[0357] Optionally, at least two time units can be transmitted continuously or at equal intervals. In the case of equal-interval transmission, the interval can be indicated by other devices (such as network-side devices). Furthermore, the interval can be counted based on Available or Physical, specifically indicated by other devices or agreed upon by the protocol.

[0358] Example 2, taking the following scheme as an example: The first device transmits first information, wherein the first information includes phase change information, and / or power change information, and / or delay change information of the first RS transmitted on at least two first time units, or the first information includes phase change information, and / or power change information, and / or delay change information of the first RS transmitted within the first time window.

[0359] Single report

[0360] One implementation step involves a first device receiving a request to report phase change information of a first RS (Real RS) from multiple transmitted first RSs. Optionally, the request type may be a one-shot report.

[0361] Optionally, for a One-Shot request, the request content includes:

[0362] Feedback time requirements, such as requiring a response within a certain period of time after the request.

[0363] The first device reports the phase change information of the first RS in the multiple transmissions of the first RS.

[0364] Optionally, a single report may include information on the phase changes corresponding to at least one RS burst or RS instance transmission, such as... Figure 29 As shown.

[0365] Furthermore, the first device indicates at least one of a first timestamp and a second timestamp in the report. The first timestamp is the timestamp of the first RS with a misaligned phase; the second timestamp is the timestamp corresponding to an RS burst or instance. Optionally, an RS burst or instance can be understood as: an RS transmission in one cycle of periodically transmitted RS, a single RS transmission, an RS transmission within a first window, etc.

[0366] Periodic reporting

[0367] One implementation step involves a first device receiving a request to report phase change information of a first RS (Real-Time Signal) from multiple transmitted first RSs (Real-Time Signals). Optionally, the request type can be periodically reported, such as... Figure 30 As shown.

[0368] Event-triggered reporting

[0369] One implementation step involves a first device receiving a request to report phase change information of a first RS in multiple transmitted first RS data sets. Optionally, the request type is event-triggered reporting.

[0370] Optionally, for event-triggered requests, the request content includes:

[0371] Event information, such as events in the second event, or a phase change occurring in the first RS transmission;

[0372] Feedback time (or feedback time requirement) refers to the time required for reporting and responding to an event after it has occurred.

[0373] Optionally, the first device detects event information, and if detected, reports the phase change information of the first RS in the multiple transmissions of the first RS.

[0374] Optionally, if event information is detected, phase change information is reported for a period of time after the last RS in each RS burst or instance, such as... Figure 31 As shown.

[0375] Optionally, the reporting time requirement may be indicated by other devices or agreed upon by a protocol.

[0376] Optionally, if event information is detected, phase change information is reported within a certain period after the last RS in every N RS bursts or instances. Optionally, N can be specified by the protocol or indicated by other devices. Optionally, if N>1, the scope of the phase change information is the N RS bursts or instances preceding the report.
