It should be understood that such terms are interchangeable when appropriate, so that the embodiments of the present application can be implemented in an order other than that shown or described herein, and the objects distinguished by "first" and "second" are generally of the same type without limiting the number of objects.

[0019] It should be noted that the technologies described in the embodiments of this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but are also applicable to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of this application are always used interchangeably, and the technologies described may be used for the systems and radio technologies mentioned above, or for other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and uses NR terminology in most of the following descriptions, but these technologies are also applicable to applications other than NR system applications, such as sixth-generation (6) radio. th It may be applied to 6G (Generation 1) communication systems.

[0020] Figure 1 shows a block diagram of a wireless communication system to which an embodiment of this application can be applied. The wireless communication system includes a terminal 11 and a network-side device 12. Here, the terminal 11 is a mobile phone, tablet personal computer, laptop computer (or notebook computer), personal digital assistant (PDA), palmtop computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, vehicle user equipment (VUE), pedestrian user equipment (PUE), smart home (home appliances with wireless communication capabilities, such as refrigerators, televisions, washing machines or furniture), game console, personal computer (personal The terminal-side equipment may be a computer (PC), a deposit machine or self-service machine, and the wearable device includes smartwatches, smart bands, smart earphones, smart glasses, smart accessories (smart bracelets, smart rings, smart necklaces, smart anklets, etc.), smart wristbands, smart clothing, etc. It should be noted that the embodiments of this application do not limit the specific type of terminal 11. The network-side equipment 12 may include access network equipment or core network equipment, where access network equipment may be called radio access network equipment, radio access network (RAN), radio access network function or radio access network unit.Access network equipment may include base stations, wireless local area network (WLAN) access points, or WiFi nodes, and base stations may also be called node B, evolutionary node B (eNB), access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), home B node, home evolutionary B node, transmitting and receiving point (TRP), or any other appropriate term in the art, and the base station is not limited to any particular technical term as long as the same technical effect is achieved. For the purposes of this explanation, only base stations in NR systems are given as examples in the embodiments of this application, but this does not limit the specific types of base stations.

[0021] Selectively, the scenarios to which the embodiments of this application apply include, but are not limited to, CSI measurement and reporting, CSI prediction and reporting, etc. By methods such as artificial intelligence (AI) and / or machine learning (ML), the terminal can predict the CSI at one or more future times by measuring already transmitted CSI-RS, and report the predicted CSI to the base station, thereby allowing the base station to acquire the CSI corresponding to future times and overcoming performance loss due to channel changes over time.

[0022] Selectively, the Channel State Information-Reference Signal (CSI-RS) in the embodiments of this application is selectively periodic or semi-persistent CSI-RS. The periodic or semi-persistent CSI-RS may be transmitted at a period configured by higher-layer signaling, such as radio resource control (RRC) signaling or medium access control (MAC) signaling. The periodic or semi-persistent CSI-RS is a commonly used CSI-RS time-domain type and may be used in aperiodic, semi-persistent, or periodic CSI reports. By using periodic or semi-persistent CSI-RS for CSI prediction, terminals and base stations can reliably monitor channel quality and obtain stable and reliable CSI.

[0023] A CSI reference resource is defined on a slot preceding the CSI report and is suitable for the characteristics of CSI prediction, i.e., the reported CSI should predict the CSI at a future time. Therefore, an embodiment of the present application provides a method for determining a CSI reference resource, where the CSI reference resource related to the CSI report is located on at least one of at least N time units after the time domain resource where the uplink channel carrying the CSI report is located, where N is a positive integer and the time unit is, for example, a slot or an OFDM symbol. This is suitable for the characteristics of CSI prediction, i.e., the reported CSI should predict the CSI at a future time.

[0024] In the following sections, the information determination method, apparatus, communication equipment, and readable storage medium according to the embodiments of this application will be described in detail with reference to several embodiments and their application scenarios, while linking them to the drawings.

[0025] Referring to Figure 2, Figure 2 is a flowchart of an information determination method according to an embodiment of the present application, and this method is applied to communication equipment, which is selectively a terminal or network-side equipment, and this network-side equipment is, for example, a base station. As shown in Figure 2, this method includes the following steps.

[0026] Step 21: The communications equipment determines that the reference resources related to the CSI report are located in the first time domain unit.

[0027] In this embodiment, the first time-domain unit includes at least one time-domain unit located at least N time units after the first time-domain resource, the first time-domain resource being the time-domain resource on which the uplink channel carrying the CSI report resides, and N being a positive integer. That is, the first time-domain unit is located after the first time-domain resource and separates it from the first time-domain resource by at least N time units. The time units are, for example, slots or orthogonal frequency division multiplexing (OFDM) symbols.

[0028] Thus, CSI reference resources may be placed on a time domain unit following the relevant CSI report, thereby making the characteristics of CSI prediction, namely, suitable for the reported CSI to predict the CSI at future times.

[0029] Selectively, the above time domain unit may include, but is not limited to, at least one of slots, slot groups, OFDM symbols, OFDM symbol groups, etc. Here, the slot group consists of a plurality of slots that are consecutive or equally spaced, and the OFDM symbol group consists of a plurality of OFDM symbols that are consecutive or equally spaced. For example, if the first time domain unit is a slot, the interval between the slot and the CSI report is N slots, or if the first time domain unit is a slot group, the interval between the first slot of the slot group and the CSI report is N slots, and the N slots may be a plurality of consecutive slot units, or a plurality of slot units with an integer number of slots spaced uniformly apart. For example, if the first time domain unit is an OFDM symbol, the interval between the OFDM symbol and the CSI report is N OFDM symbols, or if the first time domain unit is an OFDM symbol group, the interval between the first OFDM symbol of the OFDM symbol group and the CSI report is N OFDM symbols, and the N OFDM symbols may be a series of consecutive OFDM symbol units, or an integer number of OFDM symbols spaced evenly apart.

[0030] Selectively, the value of N above may be determined by a first signaling and / or terminal capability reporting signaling of the network-side equipment. The first signaling may include at least one of the following: higher-layer signaling, downlink control information (DCI), etc. The higher-layer signaling is, for example, RRC signaling, MAC signaling, etc.

[0031] For example, the value of N may be determined by triggering the DCI of the CSI. Furthermore, the value of N may be determined by triggering at least one of the dedicated domains and / or CSI request domains in the DCI of the CSI. That is, the value of N is determined by triggering the dedicated domains and / or CSI request domains in the DCI of the CSI.

[0032] It can be understood that CSI prediction allows terminals to report CSI for future times, thereby reducing the impact of channel time-dependent changes on base stations applying CSI for precoding or beam acquisition. In this case, the CSI reported by the terminal should correspond to a downlink transmission at a future time. Therefore, the CSI reference resource should be defined for a future time; that is, the CSI reference resource related to the CSI report is located in N slots or OFDM symbols after the time-domain resource where the uplink channel carrying the CSI report resides.

[0033] For example, as shown in Figure 3, Figure 3 shows an example of a reference resource definition in CSI prediction. For a CSI report on slot n, the CSI reference resource is defined as the predicted slot, i.e., slot n+N, where the value of N may be determined by base station signaling or terminal capability signaling, or, for example, by higher layer signaling or DCI. In some other examples, the CSI reported by the terminal may be used to predict the channel state at multiple points in the future. The CSI reference resource may be defined on multiple time domain units over a certain period after the CSI report, and the time domain unit may be at least one of a slot, a slot group, an OFDM symbol, or an OFDM symbol group.

[0034] Furthermore, the definition of the starting position corresponding to the N value, i.e., slot (or OFDM symbol) n, may be earlier than the slot n in which the CSI report resides. For example, n may be the N0 slots (or OFDM symbols) preceding the slot in which the CSI report resides. For example, for a CSI report on slot n0, the CSI reference resource may be located on multiple time domain units starting from slots n0-N0+N, or slots n0-N0+N. The value of N0 may be determined by network-side equipment signaling and / or terminal capability reporting signaling, for example, a value equal to or greater than M below.

[0035] Selectively, in embodiments of the present application, CSI-RS no later than a first time-domain position is used in the calculation of the CSI report, and CSI-RS later than the first time-domain position is not used in the calculation of the CSI report, thereby ensuring that the terminal has sufficient time for the predicted CSIs to be included in the CSI report. Here, the first time-domain position is a time-domain position located M time units before the time-domain resource where the uplink channel carrying the CSI report is located, i.e., the first time-domain position is located before the time-domain resource where the uplink channel carrying the CSI report is located, and is separated from the time-domain resource by M time units, where M is a positive integer.

[0036] Selectively, the value of M may be determined by at least one of the following: signaling from network-side equipment (e.g., upper-layer signaling, DCI, etc.), terminal capability reporting signaling, and predefined information.

[0037] Selectively, the first time-domain location and the CSI reference resource are located in different time-domain locations, thereby ensuring the calculation of the CSI report.

[0038] It should be noted that after the CSI reference resource is defined as a future slot, the timing of the CSI-RS for calculating the CSI report must be further defined to ensure that the terminal has sufficient time to include the predicted CSI in the CSI report. Specifically, a target time-domain position (i.e., the first time-domain position described above) must be defined, and CSI-RS that are not later than the target time-domain position are used to calculate the CSI report, while CSI-RS that are later than the target time-domain position are not used to calculate the CSI report. The target time-domain position and the CSI reference resource do not have to be in the same time-domain position. The target time-domain position is M slots or OFDM symbols preceding the time-domain resource where the uplink channel carrying the CSI report is located. For example, for a CSI report on slot n, the target time-domain position is slot nM. Alternatively, the target time-domain position is M OFDM symbols away from the first (or last) OFDM symbol occupied by the uplink channel carrying the CSI report.

[0039] Furthermore, the value of M may be fixed or determined by an agreed-upon rule. The value of M may be determined by base station signaling, for example, based on the number of CSI-RS resources configured by the base station or the type of CSI report. The value of M may be determined by terminal capability reporting signaling. For example, the value of M may be determined based on Z1 or Z'1 in Table 1 below, which is determined by terminal capability reporting signaling, or based on at least one of Z1, Z'1, Z2, Z'2, Z3 and Z'3 in Table 2 below, which is determined by terminal capability reporting signaling. Here, Table 1 shows CSI calculation delay requirement 1, Table 2 shows CSI calculation delay requirement 2, and X in Table 2 i and KB iIn all cases, these values ​​are determined based on terminal capability reporting signaling. For example, if the subcarrier spacing information is "1", terminal capability reporting signaling determines that the CSI calculation delay is Z1 in Table 1, i.e., "13 symbols", and the value of M may be 13 symbols. Alternatively, for example, if the subcarrier spacing information is "3", terminal capability reporting signaling determines that the CSI calculation delay is Z2 in Table 2, i.e., "152 symbols", and the value of M may be 152 symbols. Or, the unit of M is slots, and the value of M is determined by converting at least one of Z1, Z'1, Z2, Z'2, Z3, and Z'3 in Table 1 or Table 2 into the number of slots, for example, by dividing at least one of Z1, Z'1, Z2, Z'2, Z3, and Z'3 by the number of OFDM symbols in one slot (e.g., 14) and then rounding to the nearest integer (rounding up or down) to obtain M.

[0040] [Table 1]

[0041] [Table 2]

[0042] In some other examples, it may be necessary to flexibly define the time corresponding to the CSI report, and the CSI report may need to correspond to past or future time. In this example, the value of N in the above method may be flexibly determined by the base station configuration and may include positive or negative values, i.e., the CSI reference resources related to the CSI report are located in N slots or OFDM symbols after or before the time-domain resource where the uplink channel carrying the CSI report is located.

[0043] In the embodiments of this application, the objective of enhancing measurement performance or reducing CSI-RS overhead can be achieved by optimizing the periodic or semi-persistent CSI-RS configuration parameters for the CSI-RS used in the CSI report.

[0044] Selectively, the CSI-RS configuration parameters related to the above CSI report may include at least one of L, S, and T, where L, S, and T are positive integers, L being the number of consecutive CSI-RS transmission occasions in a first transmission occasion set, S being the number of time units between two adjacent first transmission occasion sets, and T being the number of time units between two adjacent CSI-RS transmission occasions in a first transmission occasion set. The first transmission occasion set refers to a CSI-RS transmission occasion set. The time units are, for example, slots or OFDM symbols. In this way, the CSI-RS transmission occasions can be flexibly configured using L, S, and / or T in the CSI-RS configuration parameters. For example, L may be used to configure multiple consecutive CSI-RS transmission occasions in a set of CSI-RS transmission occasions, thereby increasing the number of CSI-RS transmission occasions and ensuring measurement performance. Alternatively, for example, S and / or T may be used to flexibly configure the spacing between adjacent CSI-RS transmission occasions, thereby achieving the objective of reducing CSI-RS overhead.

[0045] Selectively, S is an integer greater than or equal to M + N.

[0046] For example, in the CSI-RS configuration parameters related to the CSI report, L, S, and T are as shown in Figure 3: L is the number of consecutive CSI-RS transmission occasions in a transmission occasion set, S is the number of slots or OFDM symbols between two adjacent transmission occasion sets, and T is the number of slots or OFDM symbols between two adjacent CSI-RS transmission occasions in a transmission occasion set.

[0047] This objective can be achieved selectively by configuring a combination of multiple CSI-RS resources to improve measurement performance. Specifically, a CSI-RS resource configuration associated with a CSI report may include K CSI-RS resources, where the K CSI-RS resources are associated with a combination of P CSI-RS resources, and where K and P are positive integers.

[0048] Selectively, each combination of CSI-RS resources may include at least one of a set of CSI-RS resources and some of the resources within that set of CSI-RS resources.

[0049] Selectively, the CSI-RS resources included in each combination of CSI-RS resources may be determined by at least one of the following:

[0050] 1) An identifier for the associated combination of CSI-RS resources may be configured for a CSI-RS resource. For example, an identifier for the associated combination of CSI-RS resources may be configured for a CSI-RS resource by network-side signaling. For example, if there are four CSI-RS resources, they are CSI-RS resources 0, 1, 2, and 3, and these four CSI-RS resources are associated with two combinations of CSI-RS resources, and CSI-RS resources 0 and 3 are associated with CSI-RS resource combination 1, and CSI-RS resources 1 and 2 are associated with CSI-RS resource combination 2. In this case, the identifier for the combination of CSI-RS resources "1" can be used to determine that the corresponding included CSI-RS resources are CSI-RS resources 0 and 3, and the identifier for the combination of CSI-RS resources "2" can be used to determine that the corresponding included CSI-RS resources are CSI-RS resources 1 and 2.

[0051] 2) The order of CSI-RS resources in the CSI-RS resource configuration. For example, if there are four CSI-RS resources, the configuration order is CSI-RS resource 0, 1, 2, and 3 in order, and these four CSI-RS resources are associated with two combinations of CSI-RS resources, with the first and second CSI-RS resources associated with CSI-RS resource combination 1, and the third and fourth CSI-RS resources associated with CSI-RS resource combination 2. In this case, the order of the configured CSI-RS resources can be used to determine that the combination of CSI-RS resources corresponding to identifier "1" includes CSI-RS resources 0 and 1, and the combination of CSI-RS resources corresponding to identifier "2" includes CSI-RS resources 2 and 3.

[0052] Selectively, resource selection instructions in CSI reports are included in each combination of CSI-RS resources.

[0054] When a terminal processes periodic or semi-persistent CSI-RS, it is necessary to cache sampling points or results after sampling point processing in the CSI-RS in order to calculate the CSI report. CSI prediction requires the terminal to calculate the CSI at future times using CSI-RS measured at multiple time points. Therefore, the terminal needs to cache CSI-RS sampling points or results after sampling point processing for multiple CSI-RS transmission occasions, thus resulting in relatively large memory and computational complexity for the terminal. In particular, when periodic or semi-persistent CSI-RS is used to calculate aperiodic CSI reports, the aperiodic CSI reports are dynamically triggered by the base station via DCI signaling, and as shown in Figure 4, the terminal cannot predict at what time the base station will trigger the CSI report. Therefore, it is necessary to always prepare for the calculation of the CSI report, and the memory space and complexity issues are especially serious.

[0055] One possible solution to the above problem is to increase the time occupied by the CSI Processing Unit (CPU) for the CSI report, and another possible solution is to increase the number of active CSI-RS resources or ports occupied by the CSI report. In this way, the complexity of the calculations or memory required by the terminal can be accurately known by network-side equipment, such as a base station, and the network-side equipment, such as a base station, can perform appropriate CSI and CSI-RS triggering, activation, or configuration based on the terminal's capabilities to avoid exceeding the terminal's processing capacity, thereby reducing the complexity of the terminal's CSI processing and achieving the objective of controlling the terminal to calculate the memory overhead required for CSI.

[0056] To selectively increase the CPU occupancy time of the CSI report, the CPU occupancy time of the CSI report may be from the first time unit of the fourth resource in the Jth CSI-RS transmission occasion prior to the first time domain position or CSI reference resource until the end of the CSI report transmission. Here, the first time domain position is a time domain position located M time units prior to the time domain resource where the uplink channel carrying the CSI report is located; that is, the first time domain position is located prior to the time domain resource where the uplink channel carrying the CSI report is located, and separates it from the time domain resource where the uplink channel carrying the CSI report is located by M time units. The CSI reference resource is optionally the reference resource described in the above embodiment. The fourth resource may include a CSI-RS resource and / or a CSI-IM resource, etc. M is a positive integer, and J is a positive integer.

[0057] Selectively, the value of J may be determined by terminal capability reporting signaling and / or network-side equipment signaling. Alternatively, the value of J may be a fixed value that is set in advance.

[0058] To selectively increase the number of active CSI-RS resources or ports occupied by a CSI report, each CSI-RS resource associated with a CSI report may be counted as Q active CSI-RS resources, or each CSI-RS port associated with a CSI report may be counted as Q active CSI-RS ports, where Q is a positive integer.

[0059] Selectively, the value of Q may be determined by terminal capability reporting signaling and / or network-side equipment signaling. Alternatively, the value of Q may be a fixed value that is set in advance.

[0060] In some embodiments, the values ​​of J and / or Q may relate to base station configuration signaling, for example, to base station codebook configuration parameters. For example, the values ​​of J and / or Q may be determined by a proportional value of a codebook configuration parameter, or by adding a proportional value of a codebook configuration parameter to a value determined by terminal capability reporting signaling, the proportional value of which may be reported by terminal capability signaling.

[0061] Referring to Figure 5, Figure 5 is a flowchart of an information determination method according to an embodiment of the present application, and this method is applied to communication equipment, which is selectively a terminal or network-side equipment, and this network-side equipment is, for example, a base station. As shown in Figure 5, this method includes the following steps.

[0062] Step 51: The communication device determines, based on the second signaling and / or pre-configured rules, whether the second resource can be used to map the first target.

[0063] In this embodiment, the second resource is a resource occupied by a CSI-RS located on the first resource or the first resource set. The first object includes at least one of a first channel and a first signal. The fact that the second resource can be used to map the first object may be understood as being able to cancel the transmission and measurement of the CSI-RS in the second resource and transmit the first object using the second resource.

[0064] Selectively, the second signaling described above may be signaling from network-side equipment, such as Downlink Control Information (DCI) or Media Access Control Element (MAC CE). The second signaling described above is, The resources occupied by CSI-RS cannot be used to map the first channel, The resources occupied by CSI-RS cannot be used to map the first signal, The resources occupied by CSI-RS can be used to map the first channel, The resources occupied by the CSI-RS can be used to indicate at least one of the following: that they can be used to map the first signal.

[0065] Selectively, the first channel described above may include, but is not limited to, at least one of the following: a Physical Downlink Shared Channel (PDSCH), a Physical Uplink Shared Channel (PUSCH), etc.

[0066] Selectively, the first signal described above may include, but is not limited to, Zero Power (ZP) CSI-RS, etc.

[0067] Selectively, the pre-configured rules described above may be predetermined, agreed upon by a protocol, and / or configured by the network side. For example, network-side equipment, such as a base station, can transmit the pre-configured rules to a terminal by signaling.

[0068] For example, the pre-configured rule described above may stipulate that resources occupied by a CSI-RS located on the first resource or the first resource set can be used to map the first object. In this way, based on this pre-configured rule, it can be directly determined whether resources occupied by a CSI-RS located on the first resource or the first resource set can be used to map the first object. Furthermore, resources occupied by a CSI-RS not located on the first resource or the first resource set cannot be used to map the first object.

[0069] For example, if a second signaling is received and the second signaling indicates that a resource occupied by a CSI-RS located on the first resource set can be used to map the first object, it can be determined that a resource occupied by a CSI-RS located on the first resource set can be used to map the first object. If the received second signaling indicates that a resource occupied by a CSI-RS located on the first resource set cannot be used to map the first object, it is determined that a resource occupied by a CSI-RS located on the first resource set cannot be used to map the first object.

[0070] The information determination method of the embodiment of this application can determine whether a second resource can be used to map a first object based on a second signaling and / or a pre-set rule, wherein the second resource is a resource occupied by a CSI-RS located on the first resource or the first resource set, and the first object includes at least one of a first channel and a first signal. This allows resources occupied by CSI-RS in some resources to be used for other channels and / or signals, thereby reducing the overhead of the reference signal CSI-RS and improving the transmission performance of the data channel when performing CSI measurements using periodic or semi-persistent CSI-RS.

[0071] For example, CSI prediction allows a base station to obtain the channel state for future times by having the terminal predict and report the CSI for a future time. For periodic or semi-persistent CSIs, after the terminal predicts the CSI for a future time, CSI-RS in some CSI-RS transmission occasions (or transmission cycles) may be canceled because it is no longer needed, i.e., the resources occupied by CSI-RS in these resources can be mapped to other channels and / or signals to reduce CSI-RS overhead and terminal complexity.

[0072] In some embodiments, a terminal may cancel reception or measurement on a resource of a CSI-RS resource unit (Resource Element, RE) by a predefined rule or base station signaling, and the canceled CSI-RS RE may be used to map resources on other channels or signals, for example, for PDSCH or PUSCH RE mapping, or it may be converted into a signal such as ZP CSI-RS.

[0073] In some embodiments, base station instruction signaling (e.g., DCI or MAC CE) can indicate at least one of the following three states for CSI-RS RE on several resources:

[0074] - State 1: CSI-RS RE is not canceled, meaning CSI-RS RE cannot be used for resource mapping of PDSCH or other channels (e.g., PUSCH), signals. - State 2: The CSI-RS RE is canceled, and the CSI-RS RE can be used for resource mapping on PDSCH or other channels (e.g., PUSCH). - State 3: The CSI-RS RE is canceled and converted to a ZP CSI-RS RE, or the CSI-RS RE may be converted to other signal resources, for example, an interference measurement resource that includes at least one of the following resources: Channel State Information-Interference Measurement (CSI-IM), Non-zero-power (NZP) CSI-RS based interference measurement, etc.

[0075] In further embodiments, the candidate values ​​for base station instruction signaling may include only state 1 or state 2. Furthermore, whether or not state 3 is included may be determined by base station configuration signaling or terminal capability signaling.

[0076] For example, an example of base station instruction signaling is shown in Figures 6A, 6B, and 6C. In this example, UE1 predicts the CSI for a future time using an AI / ML algorithm, so the base station can cancel some CSI-RS transmissions and measurements for UE1. To save CSI-RS overhead, the base station has UE1, UE2, and UE3 share a set of CSI-RS configurations, and therefore canceling UE1's CSI-RS affects UE2 and UE3, and thus in this example, 1) As shown in Figure 6A, the base station instructs UE1 to use the CSI-RS RE that was canceled by UE1 to map the PDSCH RE in order to improve the PDSCH transmission performance of UE1.

[0077] 2) As shown in Figure 6B, the CSI-RS period of UE2 is configured to be larger than the CSI-RS periods of UE1 and UE3, for example, twice the CSI-RS period of UE1 and UE3. In this way, in locations where UE2 does not receive CSI-RS, a periodic ZP CSI-RS resource is configured on UE2 to cover the CSI-RS RE there, thereby reducing interference to UE2 by CSI-RS in this location. At this time, the CSI-RS RE canceled by UE1 is used for PDSCH mapping and does not affect UE2.

[0078] 3) UE3 originally shares CSI-RS resources with UE1 at the same frequency, and when the base station instructs UE1 to use its CSI-RS RE for PDSCH RE mapping, it affects UE3's CSI-RS measurement. At the same time, as shown in Figure 6C, this instruction signaling converts UE3's CSI-RS to ZP CSI-RS, eliminating the influence of UE1's PDSCH transmission on UE3's CSI-RS measurement.

[0079] Based on the above analysis, by including base station instruction signaling in the three states described above, it is possible to reduce the RS overhead of the target UE, increase the PDSCH transmission resources of the target UE, and achieve the technical effect of not affecting other UEs.

[0080] In embodiments of this application, the first resource or first resource set described above may include, but is not limited to, at least one of the following: a CSI-RS transmission occasion, a CSI-RS period, a CSI-RS resource, an Orthogonal Frequency Division Multiplexing (OFDM) symbol including CSI-RS, a slot resource including CSI-RS, a frequency domain resource including CSI-RS, or a first channel resource scheduled by network-side equipment.

[0081] Selectively, the first resource or first resource set described above may be determined based on at least one of a third signaling of network-side equipment (e.g., a base station) and a predefined rule. For example, the first resource or first resource set is a transmission occasion of CSI-RS that is in a time window indicated by the third signaling, or selected by the third signaling in a time resource set or time window, an OFDM symbol containing CSI-RS or a slot resource containing CSI-RS, or a resource selected by the third signaling in one or more resource sets.

[0082] Selectively, the third signaling may include at least one of the upper-layer signaling and the downlink control information DCI. The upper-layer signaling is, for example, RRC signaling, MAC signaling, etc.

[0083] Selectively, the first resource or set of resources described above may include a CSI-RS transmission occasion between a second time-domain resource and a third time-domain resource, where the second time-domain resource includes at least one of 1) a time unit in which a DCI triggering a CSI report is located, 2) a time unit in which an uplink channel carrying the CSI report is located, and 3) S time units preceding the time unit in which the uplink channel carrying the CSI report is located, where S is a positive integer. The third time-domain resource includes at least one of 1) a time unit in which an uplink channel carrying the CSI report is located, 2) a time unit in which a reference resource corresponding to the CSI report is located, or X time units following the time unit in which the uplink channel carrying the CSI report is located (e.g., a slot or OFDM symbol), where X is a positive integer, and 3) a time unit corresponding to the CSI reported by the CSI report. The time units are, for example, slots or OFDM symbols.

[0084] In some embodiments, the second time-domain resource is the time unit in which the DCI that triggers the CSI report is located, and simultaneously, the third time-domain resource is one of the time units in which the uplink channel carrying the CSI report is located, the time unit in which the reference resource corresponding to the CSI report is located, and the time unit corresponding to the CSI reported by the CSI report.

[0085] In some other embodiments, the second time-domain resource is the time unit in which the uplink channel carrying the CSI report resides, and the third time-domain resource is one of the time units in which the reference resource corresponding to the CSI report resides and the time unit corresponding to the CSI reported by the CSI report.

[0086] In some other embodiments, the second time-domain resource is S time units preceding the time unit in which the uplink channel carrying the CSI report is located, and simultaneously, the third time-domain resource is one of the time units in which the uplink channel carrying the CSI report is located, the time unit in which the reference resource corresponding to the CSI report is located, and the time unit corresponding to the CSI reported by the CSI report.

[0087] The selective cancellation of resources occupied by CSI-RS (e.g., CSI-RS RE) with respect to a first resource or a set of first resources may include, but is not limited to, at least one of the following:

[0088] 1) CSI-RS transmission occasions can be canceled at a granular level relative to CSI-RS, and CSI-RS REs in one or more CSI-RS transmission occasions can be canceled at a time, i.e., CSI-RS REs in one or more CSI-RS transmission occasions can be used to map other channels or signals.

[0089] 2) CSI-RS can be canceled at a granularity based on the CSI-RS period, and CSI-RS RE can be canceled in one or more CSI-RS periods at a time, i.e., CSI-RS RE in one or more CSI-RS periods can be used for mapping other channels or signals.

[0090] 3) CSI-RS resources can be canceled at a granular level relative to CSI-RS, and CSI-RS REs in one or more CSI-RS resources in one or more CSI-RS sets can be canceled at one time, i.e., CSI-RS REs in one or more CSI-RS resources can be used to map other channels or signals.

[0091] 4) CSI-RS can be canceled at the OFDM symbol granularity, and CSI-RS RE can be canceled in one or more OFDM symbols at a time, i.e., CSI-RS RE in one or more OFDM symbols can be used to map other channels or signals.

[0092] 5) CSI-RS can be canceled at the slot level, canceling CSI-RS RE in one or more slots at a time, i.e., CSI-RS RE in one or more slots can be used to map other channels or signals.

[0093] 6) Frequency domain resources can be canceled with respect to CSI-RS at a granularity, and CSI-RS REs in one or more frequency domain resources can be canceled at a time, i.e., CSI-RS REs in one or more frequency domain resources can be used to map other channels or signals. The frequency domain resources may be subbands, resource blocks (RB), resource block groups (RBG), resource element groups (REG), etc.

[0094] 7) The PDSCH allocation resource for CSI-RS is canceled at a granular level, and the CSI-RS RE included in a scheduled PDSCH resource is canceled once, meaning that the CSI-RS RE included in this scheduled PDSCH resource can be used to map other channels or signals.

[0095] It should be noted that the above 1) through 7) may be used in combination. For example, canceling the CSI-RS RE of one or more CSI-RS resources in one or more CSI-RS transmission occasions at once, or canceling the CSI-RS RE of one or more CSI-RS resources in one or more slots (or OFDM symbols) at once.

[0096] Furthermore, the specific method for determining which resources at which locations need to have their included CSI-RS REs canceled may include at least one of the following:

[0097] (1) A canceled CSI-RS RE is located within a time window and cancels all CSI-RS REs in all CSI-RS transmission occasions (or periods, OFDM symbols, slots) within that time window. The time window can be determined by base station signaling or agreed-upon rules, which determine its start time position, length, or end time position.

[0098] (2) The canceled CSI-RS RE is located on a portion of time resources selected from a time window or set of time resources, for example, after determining a time window, base station signaling (e.g., bitmap signaling) selects a portion of the transmission occasions (or periods, OFDM symbols, slots) included in this time window and cancels the CSI-RS RE on this selected portion of resources.

[0099] (3) A canceled CSI-RS RE is a CSI-RS RE in some of the CSI-RS resources selected from one or more configured sets of CSI-RS resources.

[0100] (4) A canceled CSI-RS RE is a CSI-RS RE that is included in a PDSCH resource scheduled by base station signaling.

[0101] It should be noted that the above (1) to (4) may be used in combination. The base station signaling may be upper-layer signaling (e.g., RRC or MAC signaling) or physical-layer signaling (e.g., DCI).

[0102] Furthermore, the above CSI-RS cancellation method may be determined by predefined rules. For example, for a given CSI report (e.g., a CSI report of a particular codebook type or feedback type), the CSI-RS between the start time position and the end time position may be determined. The RE is canceled, where the start time position is at least one of 1) the slot or OFDM symbol where the DCI that triggers the CSI report is located, 2) the slot or OFDM symbol where the uplink channel carrying the CSI report is located, and 3) S slots or OFDM symbols prior to the slot or OFDM symbol where the uplink channel carrying the CSI report is located, and the end time position is at least one of 1) the slot or OFDM symbol where the uplink channel carrying the CSI report is located, 2) the slot or OFDM symbol where the CSI reference resource corresponding to the CSI report is located, or X slots or OFDM symbols after the slot or OFDM symbol where the uplink channel carrying the CSI report is located, where X is a positive integer, and 3) the slot or OFDM symbol corresponding to the CSI reported by the CSI report.

[0103] Selectively, the second signaling described above may include at least one of the following:

[0104] 1) Uplink scheduling DCI, i.e., DCI for scheduling uplink channels. This only indicates that this DCI can be used to schedule uplink channels, and does not mean that this DCI actually scheduled a transmission on an uplink channel.

[0105] In this 1), the mapping state of resources occupied by CSI-RS may be indicated by at least one of the dedicated domains and CSI request domains in the uplink scheduling DCI. In other words, a dedicated domain instruction may be newly added to the uplink scheduling DCI for the mapping state of resources occupied by CSI-RS, an existing domain instruction may be re-decoded, or it may be coded in combination with an instruction for an existing domain, such as the CSI request domain.

[0106] Furthermore, when the CSI request domain in the Uplink Scheduling DCI specifies the mapping state of resources occupied by the CSI-RS, the mapping state of resources occupied by the CSI-RS can be configured in the CSI trigger states. Alternatively, the above-mentioned time window information, resource information, etc., may be configured using the Uplink Scheduling DCI.

[0107] 2) Downlink scheduling DCI, i.e., DCI for scheduling downlink channels. This merely indicates that this DCI can be used to schedule downlink channels, and does not mean that this DCI has actually scheduled a transmission on a downlink channel.

[0108] In this 2), the mapping state of resources occupied by CSI-RS may be indicated by at least one of the dedicated domain, resource allocation domain, and ZP CSI-RS instruction domain in the downlink scheduling DCI. In other words, a dedicated domain instruction may be newly added to the downlink scheduling DCI for the mapping state of resources occupied by CSI-RS, an existing domain instruction may be re-decoded, or it may be coded in combination with the instruction of a subordinate existing domain, such as a resource allocation domain or a ZP CSI-RS instruction domain.

[0109] Furthermore, when the resource allocation domain in the Downlink Scheduling DCI specifies the mapping state of resources occupied by CSI-RS, the mapping state of resources occupied by CSI-RS can be configured in the resource allocation state, or when the ZP CSI-RS instruction domain in the Downlink Scheduling DCI specifies the mapping state of resources occupied by CSI-RS, the mapping state of resources occupied by CSI-RS can be configured in the ZP CSI-RS state. In addition, the above-mentioned time window information, resource information, etc., can be configured using the Downlink Scheduling DCI.

[0110] 3) Group common DCI.

[0111] In step 3), the mapping status of resources occupied by CSI-RS may be indicated by a dedicated domain in the group common DCI. In other words, a new group common DCI format may be added to the mapping status of resources occupied by CSI-RS and indicated by a dedicated domain.

[0112] 4) Media access control element MAC CE.

[0113] It should be noted that the mapping state of the resources occupied by the CSI-RS is selectively at least one of the following: the resources occupied by the CSI-RS cannot be used to map the first channel; the resources occupied by the CSI-RS cannot be used to map the first signal; the resources occupied by the CSI-RS can be used to map the first channel; or the resources occupied by the CSI-RS can be used to map the first signal.

[0114] In the embodiments of this application, a certain time limit is required for the rejection of CSI-RS REs indicated by the base station, such that CSI-RS REs located in at least F slots or OFDM symbols after the slot or OFDM symbol where the base station indicated signaling resides can be used to map other channels or signals. That is, the second resource is located after the time unit in which the first signaling resides and at least F time units apart from the time unit in which the first signaling resides, where F is a positive integer. The time unit is, for example, a slot or an OFDM symbol.

[0115] Selectively, if the canceled CSI-RS is a semi-persistent CSI-RS, in the first time period, the terminal does not receive the second signaling, or the terminal ignores the second signaling, and at this time, the network-side equipment can transmit the second signaling. Alternatively, in the first time period, the network-side equipment does not transmit the second signaling. Here, the start point of the first time period is the transmission time of the fourth signaling or the feedback time of the fourth signaling, the fourth signaling is a signaling that activates the semi-persistent CSI-RS, the length of the first time period is G time units, and G is a positive integer.

[0116] For example, in the case of semi-persistent CSI-RS, if a signaling to activate semi-persistent CSI-RS (e.g., MAC CE signaling or DCI signaling) is transmitted or within the time G length after the acknowledgment / negation (ACK / NACK) corresponding to this signaling, the terminal cannot receive a base station instruction signaling for CSI-RS cancellation. In one example, G is an integer number of OFDM symbols or slots, and in another example, G is a time length in ms, e.g., 3ms. Similarly, if a signaling to deactivate semi-persistent CSI-RS (e.g., MAC CE signaling or DCI signaling) is transmitted or within the time G length after the ACK / NACK corresponding to this signaling, the UE cannot receive a base station instruction for CSI-RS cancellation, in one example, G is an integer number of OFDM symbols or slots, and in another example, G is a time length in ms, e.g., 3ms.

[0117] Selectively, the terminal may report information about a recommended primary resource or primary resource set, thereby enabling efficient configuration by making it available to network-side devices. For example, the terminal may report in a CSI report the CSI-RS RE information to be removed, such as CSI-RS resource or port information, or the time window or resource location information of the CSI-RS RE to be removed.

[0118] Selectively, the above CSI-RS removal can affect the calculation of the terminal's CSI Processing Unit (CPU) occupation and active CSI-RS resources (e.g., ports), and can therefore be used to map the resources (e.g., ports) occupied by the first target CSI-RS, i.e., canceled CSI-RS resources (e.g., ports) are not counted in the CSI Processing Unit (CPU) occupation or in the active CSI-RS resources (e.g., ports).

[0119] In some further examples, the CSI-RS in the above CSI-RS cancellation scheme may refer to CSI-RS used for CSI feedback, as well as CSI-RS used specifically for performance monitoring, CSI-RS used for quasi-colocation (QCL) sources, or CSI-RS used for model lifecycle management.

[0120] Selectively, the above CSI-RS cancellation method may be used for multiple types of CSI reports, such as channel quality indicator (CQI) reports, precoding matrix indicator (PMI) reports, CSI-RS resource index (CRI) reports, layer 1 reference signal receiving power (L1-RSRP) reports, layer 1 reference signal received quality (L1-RSRQ) reports, rank indicator (RI) reports, and layer indicator (LI) reports.

[0137] Selectively, the value of J is determined by terminal capability reporting signaling and / or network-side equipment signaling.

[0138] Selectively, each CSI-RS resource associated with the CSI report is counted as Q active CSI-RS resources, or each CSI-RS port associated with the CSI report is counted as Q active CSI-RS ports, where Q is a positive integer.
