[0001] Cross-reference to Related Applications

[0002] This application claims priority to Chinese Patent Application No. 201811161675.9, filed on September 30, 2018, and Chinese Patent Application No. 201811333704.5, filed on November 9, 2018, the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0004] In beam management, a terminal device can measure a plurality of transmission beams of a network device or a plurality of reception beams of itself, obtain beam measurement information, and determine whether to report the beam measurement information in CSI information to the network device according to different application scenarios. For example, when the terminal device measures a plurality of transmission beams of a base station or measures a plurality of transmission beams of the network device and a plurality of reception beams of itself, the terminal device reports the beam measurement information in the CSI information to the network device; when the network device fixes a transmission beam and the terminal device measures a plurality of reception beams of itself on the transmission beam, the terminal device reports no content, i.e., no beam measurement information, to the network device.

[0005] Generally, when performing beam measurement, a terminal device needs to occupy a CSI processing unit in the terminal device and determine the occupation time of the CSI processing unit. However, in beam management, the related art cannot determine the occupation time of the CSI processing unit.

[0050] In beam management, a network device (e.g., a Transmission Reception Point (TRP)) can have multiple transmission beams, and a terminal device can also have multiple reception beams. Generally, before communicating with the base station, the terminal device can measure the multiple transmission beams of the network device or the multiple reception beams of itself to determine the best transmission beam of the network device or the best reception beam of itself to use when communicating with the network device.

[0051] When performing beam measurement, the terminal device can be implemented by the network device through configuring Synchronisation Signal Block (SSB) resources or Channel State Information-Reference Signals (CSI-RS) resources. Signals on different SSB resources or CSI-RS resources can be transmitted through different transmission beams, and the terminal device can perform beam measurement according to the received signal strength and other parameters.

[0052] The following is described by taking three typical application scenarios as examples:

[0053] The first application scenario is that the terminal device measures the multiple transmission beams of the network device and the multiple reception beams of itself.

[0054] Specifically, the terminal device can scan the multiple reception beams of itself on each transmission beam of the network device, determine the best reception beam corresponding to each transmission beam according to the signal strength and other parameters received by the multiple reception beams, and determine one or more corresponding transmission beams based on the best reception beams.

[0055] The second application scenario is that the terminal device measures the multiple transmission beams of the network device.

[0056] Specifically, the terminal device can fix a reception beam, and can scan the multiple transmission beams of the network device on the reception beam, and determine one or more best transmission beams according to the signal strength and other parameters received from the multiple transmission beams.

[0057] The second application scenario can be regarded as a special case of the first application scenario, and compared with the first application scenario, it can implement small-range more accurate transmission beam scanning.

[0058] The third application scenario is that the terminal device measures the multiple reception beams of itself.

[0059] Specifically, the network device can fix a sending beam, and the terminal device scans multiple receiving beams of itself on the sending beam fixed by the network device, and determines one or more optimal receiving beams according to parameters such as signal strengths received by the multiple receiving beams.

[0060] The first application scenario is a combination of the second application scenario and the third application scenario. After the terminal device performs beam measurement in the three application scenarios, corresponding beam measurement information can be obtained and recorded in the terminal device. In the first application scenario and the second application scenario, the terminal device can report the beam measurement information to the network device as CSI information, so that the network device can use a suitable sending beam to communicate with the terminal device. In the third application scenario, since the sending beam of the network device is fixed, the CSI information reported by the terminal device to the network device is empty, that is, the terminal device does not report the beam measurement information to the network device. In this way, when the network device uses the fixed sending beam to communicate with the terminal device, the terminal device can select a suitable receiving beam based on the locally recorded beam measurement information.

[0061] Before the terminal device reports the beam measurement information to the network device in the form of a CSI report, the network device can indicate a CSI report configuration to the terminal device.

[0062] Specifically, the network device can send radio resource control (RRC) signaling to the terminal device, and carry a CSI report configuration (CSI-Report Config) in the RRC signaling. In beam management, the configuration options of the report quantity (reportQuantity) in the CSI report configuration can mainly include: cri-Reference Signal Receiving Power (cri-RSRP), ssb-Index-RSRP, or none.

[0063] After the terminal device receives the CSI report configuration indicated by the network device, the terminal device can obtain corresponding beam measurement information based on the indication.

[0064] When the terminal device obtains the beam measurement information, it usually needs to occupy a CSI processing unit in the terminal device. If the terminal device can support the calculation of N CSIs at the same time, it means that the terminal device has N CSI processing units. In a given orthogonal frequency division multiplexing (OFDM) symbol, if L CSI processing units in the terminal device are occupied, then the terminal device has N-L available CSI processing units.

[0065] However, in beam management, the related art cannot explicitly determine the occupation time of the CSI processing unit.

[0066] Therefore, the embodiments of the present disclosure provide a method for determining the occupation time of a channel state information (CSI) processing unit and a terminal device. The method is applied to the terminal device and includes determining the occupation time of the CSI processing unit according to a CSI reporting type in a CSI reporting configuration. The CSI reporting type includes that the CSI information reported by the terminal device to a network device is beam measurement information or that the CSI information reported by the terminal device to the network device is nothing and a channel state information reference signal (CSI-RS) resource is not used for tracking reference signal (TRS) measurement.

[0067] In the embodiments of the present disclosure, the CSI information can be understood as the reporting amount in the CSI reporting configuration being set to none.

[0068] In this way, in beam management, in the two application scenarios that the CSI information reported to the network device is beam measurement information and the CSI information reported is nothing and the CSI-RS resource is not used for TRS measurement, the occupation time of the CSI processing unit in the terminal device can be explicitly determined based on the technical solution provided in the embodiments of the present disclosure, and the behaviors of the terminal device and the network device are more clear.

[0069] The technical solutions in the embodiments of the present disclosure will be described clearly and completely in combination with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.

[0070] The technical solutions of the present disclosure can be applied to various communication systems, such as Global System of Mobile communication (GSM), Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE) / Long Term Evolution advanced (LTE-A), New Radio (NR), etc.

[0071] The terminal device can be understood as a user equipment (UE), also known as a mobile terminal (Mobile Terminal), mobile user equipment, etc., which can communicate with one or more core networks through a radio access network (e.g., Radio Access Network, RAN). The user equipment can be a mobile terminal, such as a mobile phone (or "cell" phone) and a computer with a mobile terminal, for example, which can be portable, pocket-sized, handheld, built-in to a computer, or vehicle-mounted. The user equipment can also be a drone, aircraft, or other flying device that exchanges voice and / or data with the radio access network.

[0072] The base station can be a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolved base station (eNB or e-NodeB, evolutional Node B) in LTE, and a 5G base station (gNB). The present disclosure is not limited, but for the convenience of description, the following embodiments are described taking gNB as an example.

[0073] The application scenarios of the present disclosure can include at least two application scenarios, i.e., the terminal device measures multiple transmission beams of the network device, and the terminal device measures multiple transmission beams of itself. In the two application scenarios, the terminal device can determine the occupation time of the CSI processing unit in the terminal device based on the technical solutions provided in the embodiments of the present disclosure.

[0074] The technical solutions provided in the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0075] FIG. 1 is a flowchart of a method for determining the occupation time of a channel state information (CSI) processing unit according to an embodiment of the present disclosure, which is applied to a terminal device. The method is described as follows.

[0076] S102: Determine the occupation time of the CSI processing unit according to the CSI reporting type in the CSI reporting configuration.

[0077] In S102, in the application scenario of beam measurement, when determining the occupation time of the CSI processing unit, the occupation time of the CSI processing unit can be determined according to the CSI reporting type in the CSI reporting configuration.

[0078] In the embodiments of the present disclosure, the CSI reporting type configured by the network device can include two types. One is that the CSI information reported by the terminal device to the network device is beam measurement information, and the other is that the CSI information reported by the terminal device to the network device is no content, and the CSI-RS resource is not used for tracking reference signal (TRS), that is, the high layer parameter trs-Info of the CSI-RS resource set CSI-RS-ResourceSet in the CSI resource configuration associated with the CSI report configuration is not configured. Wherein, the CSI information reported by the terminal device to the network device is no content, which can be understood as that the terminal device does not report beam measurement information to the network device.

[0079] The beam measurement information can include a beam measurement quantity corresponding to the resource number of the SSB, or a beam measurement quantity corresponding to the resource number of the CSI-RS. The beam measurement quantity can include at least one of L1-RSRP, L1-Reference Signal Receiving Quality (L1-RSRQ) and L1-Signal to Interference plus Noise Ratio (L1-SINR).

[0080] The terminal device reporting the beam measurement information to the network device can correspond to the application scenario of the terminal device measuring the multiple transmission beams of the network device. At this time, the terminal device needs to report the measured transmission beam information to the network device.

[0081] The terminal device reporting no content and the CSI-RS resource not being used for TRS measurement to the network device can correspond to the application scenario of the terminal device measuring the multiple transmission beams of the terminal device. At this time, the terminal device does not need to report the measured reception beam information to the network device.

[0082] In an embodiment of the present disclosure, when the CSI reporting type is to report the beam measurement information to the network device, the determination of the occupation time of the CSI processing unit can include:

[0083] According to the time domain characteristics of the CSI report, the occupation time of the CSI processing unit is determined.

[0084] In this embodiment, when the CSI information reported by the terminal device to the network device is beam measurement information, the occupation time of the CSI processing unit can be determined based on the time domain characteristics of the CSI report. When the CSI information reported by the terminal device to the network device is beam measurement information, the report quantity in the corresponding CSI report configuration can be set to cri-RSRP or ssb-Index-RSRP.

[0085] The time domain characteristics of the CSI report can include two types, one of which can be periodic or semi-persistent, and the other of which can be aperiodic. When the time domain characteristics of the CSI report are periodic or semi-persistent, the periodic or semi-persistent CSI report can be based on SSB resources, or can be based on periodic CSI-RS resources, or can be based on semi-persistent CSI-RS resources. When the time domain characteristics of the CSI report are aperiodic, the aperiodic CSI report can be based on SSB resources, or can be based on periodic CSI-RS resources, or can be based on semi-persistent or aperiodic CSI-RS resources. Here, no specific limitation is made.

[0086] The following will explain how to determine the occupation time of the CSI processing unit for the two different time domain characteristics of the CSI report.

[0087] In one implementation, when the time domain characteristics of the CSI report are periodic or semi-persistent, determining the occupation time of the CSI processing unit can include:

[0088] The occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource and ends at the last OFDM symbol of the physical uplink shared channel (PUSCH) or the physical uplink control channel (PUCCH) used to transmit the CSI report.

[0089] The CSI resource is the CSI resource that is transmitted for the last time Z' OFDM symbols before the first OFDM symbol of the PUSCH or the PUCCH.

[0090] In one embodiment, the CSI resource can include a type of resource, which can include at least one SSB resource or at least one CSI-RS resource configured in a CSI resource configuration (CSI-ResourceConfig) associated with the CSI report configuration.

[0091] In another embodiment, the CSI resource can also include multiple resources, which can include at least one SSB resource or at least one CSI-RS resource configured in one CSI resource configuration associated with the CSI report configuration, and at least one interference measurement resource or at least one RSSI measurement resource configured in another CSI resource configuration associated with the CSI report configuration.

[0092] That is, the CSI resource needs to include at least one SSB resource or at least one CSI-RS resource, and can further include at least one interference measurement resource or at least one RSSI measurement resource. The SSB resource or the CSI-RS resource can be used for measurement of reference signal received power, which can be L1-RSRP or a numerator corresponding to L1-SINR. The interference measurement resource can be used for measurement of noise and interference power, and the RSSI measurement resource can be used for measurement of RSSI.

[0093] It should be noted that when the CSI resource includes one resource, the first OFDM symbol in the CSI resource can be understood as the first OFDM symbol in the at least one SSB resource or the at least one CSI-RS resource. When the CSI resource includes multiple resources, the multiple resources are transmitted at one time, and the first OFDM symbol in the CSI resource can be understood as the first OFDM symbol of the resource transmitted first in the multiple resources.

[0094] The Z' can be understood as the number of OFDM symbols required by the terminal device to calculate the beam measurement information.

[0095] In the embodiments of the present disclosure, Z' can be determined by the BR in Table 1. i .

[0096] Table 1

[0097]

[0098] In order to facilitate understanding of the occupation time of the CSI processing unit, reference can be made to FIG. 2.

[0099] In FIG. 2, it is assumed that the subcarrier spacing of the terminal device (corresponding to uplink) is different from the subcarrier spacing of the network device (corresponding to downlink). Each small square represents one OFDM symbol.

[0100] In the OFDM symbols of the downlink, the 2nd to 5th OFDM symbols from the left are the OFDM symbols of the CSI resource, which is the CSI resource that is transmitted for the last time Z' OFDM symbols before the first OFDM symbol of the PUSCH or PUCCH for transmitting the CSI report.

[0101] In the OFDM symbols of the uplink, the 2nd and 3rd OFDM symbols from the right are the OFDM symbols of the PUCCH or PUSCH for transmitting the CSI report.

[0102] As can be seen from FIG. 2, the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource and ends at the last OFDM symbol of the PUSCH or PUCCH.

[0103] In general, when the terminal device reports the beam measurement information to the network device, if the time domain feature of the CSI report is periodic or semi-persistent, the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource that is transmitted for the last time Z' OFDM symbols long before the first OFDM symbol of the PUSCH or PUCCH for transmitting the CSI report (if present), and ends at the last OFDM symbol of the PUSCH or PUCCH for transmitting the CSI report.

[0104] In another implementation, when the time domain feature of the CSI report is aperiodic, determining the occupation time of the CSI processing unit can include:

[0105] The occupation time of the CSI processing unit starts from the first OFDM symbol after the physical downlink control channel (PDCCH) triggering the CSI report and ends at the last OFDM symbol of the PUSCH for transmitting the CSI report.

[0106] The PDCCH triggering the CSI report can contain downlink control information (DCI), and the network device can trigger the CSI report through the CSI request field in the DCI.

[0107] In order to facilitate understanding of the occupation time of the CSI processing unit, refer to FIG. 3.

[0108] In FIG. 3, it is assumed that the subcarrier spacing of the terminal device and the subcarrier spacing of the network device are different, and each small square represents an OFDM symbol.

[0109] In the OFDM symbols of the downlink, the 2nd to 5th OFDM symbols from the left are the OFDM symbols of the CSI resource, and the 7th and 8th OFDM symbols are the OFDM symbols of the PDCCH for triggering the CSI report.

[0110] In the OFDM symbols of the uplink, the 2nd and 3rd OFDM symbols from the right can be the OFDM symbols of the PUSCH for transmitting the CSI report.

[0111] As can be seen from FIG. 3, the occupation time of the CSI processing unit starts from the first OFDM symbol after the PDCCH triggering the CSI report and ends at the last OFDM symbol of the PUSCH transmitting the CSI report.

[0112] It should be noted that when the time-domain feature of the CSI report is non-periodic based on non-periodic CSI resource, the CSI report is updated only when the occupation time of the CSI processing unit meets the following conditions.

[0113] First: If the timing advance is considered, the first uplink OFDM symbol of the PUSCH or PUCCH transmitting the CSI report is not earlier than the Z ref th OFDM symbol, and is not earlier than the Z’ ref th OFDM symbol;

[0114] Second: The number of symbols between the last OFDM symbol of the CSI resource and the first OFDM symbol of the PUSCH or PUCCH transmitting the CSI report is greater than or equal to Z’, and the number of symbols between the first OFDM symbol of the PDCCH triggering the CSI report and the first OFDM symbol of the PUSCH or PUCCH transmitting the CSI report is greater than or equal to Z.

[0115] That is, the CSI report is updated only when it can be ensured that the beam measurement information is calculated.

[0116] Z ref may be defined as the next uplink OFDM symbol after the last OFDM symbol of the PDCCH triggering the CSI report, at which the starting time of the Cyclic Prefix (CP) is T = (Z)(2048 + 144)κ2 -μ T c (seconds).

[0117] When the CSI report is a CSI report based on non-periodic CSI-RS resource, Z’ refThe starting moment of the CP can be defined as the first OFDM symbol after T' = (Z')(2048+144)K2 from the last OFDM symbol of the non-periodic CSI-RS resource for channel measurement, the non-periodic CSI-IM (CSI Interference Measurement) resource for interference measurement, and the non-periodic NZP (Non-zero Power) CSI-RS resource for interference measurement. -μ T' c of the next uplink OFDM symbol.

[0118] For the convenience of understanding Z ref and Z' ref , refer to FIG. 4.

[0119] In FIG. 4, assuming that the subcarrier spacing used by the terminal device and the network device is the same, Z ref may be represented as the first OFDM symbol after T duration of the last OFDM symbol of the PDCCH, and Z' ref may be represented as the first OFDM symbol after T' duration of the last OFDM symbol of the CSI-RS resource and the CSI-IM resource.

[0120] Z' can represent the number of OFDM symbols for calculating beam measurement information, which is the same as Z' described in the first implementation mode.

[0121] Z is related to Z', where Z' can be determined by Table 1 described above. RB i is obtained, and the difference between Z and Z' can be a fixed value, which can be the same as the difference between Z1 and Z1' in the CSI report specified in the related art, or the same as the difference between Z2 and Z2'.

[0122] As shown in the following Table 2 and Table 3. In Table 2 and Table 3, μ = 1, 2, 3, 4 respectively correspond to subcarrier spacing 15KHz, 30KHz, 60KHz, 120kHz. Among them, Table 2 is applicable to the application scenario with low latency requirement, and Table 3 is applicable to the application scenario with high latency requirement.

[0123] Table 2

[0124]

[0125]

[0126] Table 3

[0127]

[0128] Based on the above Table 2 and Table 3, in the case of known Z', the corresponding Z can be determined.

[0129] For example, in the scenario of low latency 30KHz subcarrier spacing, if Z' is determined as 8 based on Table 1 above, according to Z1 and Z1' corresponding to 30KHz subcarrier spacing in Table 2, Z = Z1-Z1'+Z' = 10 can be obtained.

[0130] The above is a description of how to determine the occupation time of the CSI processing unit when the CSI information reported by the terminal device to the network device is beam measurement information. In the following, how to determine the occupation time of the CSI processing unit when the CSI information reported by the terminal device to the network device is no content and the CSI-RS resource is not used for TRS measurement will be described.

[0131] In an embodiment of the present disclosure, when the CSI report type is that the CSI information reported by the terminal device to the network device is no content and the CSI-RS resource is not used for TRS measurement, determining the occupation time of the CSI processing unit can include:

[0132] According to the time domain characteristics of the CSI report and the configuration of the physical uplink resource, the occupation time of the CSI processing unit is determined, and the physical uplink resource is a PUCCH resource or a PUSCH resource.

[0133] In this embodiment, the occupation time of the CSI processing unit can be determined based on the time domain characteristics of the CSI report and the configuration of the physical uplink resource (PUCCH resource or PUSCH resource). In the corresponding CSI report configuration of this embodiment, the reporting quantity can be set to none.

[0134] When the CSI information reported by the terminal device to the network device is no content, the time domain characteristics of the CSI report can also include two kinds, one can be periodic or semi-persistent, and the other can be aperiodic. When the time domain characteristics of the CSI report are periodic or semi-persistent, it can be periodic or semi-persistent CSI reporting based on SSB resources, or periodic or semi-persistent CSI reporting based on periodic CSI-RS resources, or semi-persistent CSI reporting based on semi-persistent CSI-RS resources; when the time domain characteristics of the CSI report are aperiodic, it can be aperiodic CSI reporting based on SSB resources, or aperiodic CSI reporting based on periodic or semi-persistent CSI-RS resources, or aperiodic CSI reporting based on aperiodic CSI-RS resources, which is not limited here.

[0135] The configuration of the physical uplink resource can include two cases: one is that the network device has configured the physical uplink resource for the terminal device, that is, there is a PUCCH resource or a PUSCH resource; and the other is that the network device has not configured the physical uplink resource for the terminal device, that is, there is no PUCCH resource and PUSCH resource. When the network device configures 0 physical uplink resources for the terminal device, it can be understood that the network device has not configured the physical uplink resource for the terminal device.

[0136] The following will explain how to determine the occupation time of the CSI report with respect to two different time domain characteristics of the CSI report and two different configurations of the physical uplink resource.

[0137] In the first implementation, when the time domain characteristic of the CSI report is periodic or semi-persistent, and the network device has configured the physical uplink resource, the determination of the occupation time of the CSI processing unit can include:

[0138] The occupation time of the CSI processing unit starts from the first OFDM symbol in the CSI resource and ends at the (1+x)th OFDM symbol of the periodic or semi-persistent PUCCH or PUSCH of the configured CSI report; or

[0139] The occupation time of the CSI processing unit starts from the first OFDM symbol in the CSI resource and ends at the last OFDM symbol of the periodic or semi-persistent PUCCH or PUSCH of the configured CSI report.

[0140] The CSI resource can be the earliest CSI resource in at least one CSI resource that is transmitted for the last Z' OFDM symbols before the first OFDM symbol of the PUSCH or the PUCCH.

[0141] The CSI resource needs to include at least one SSB resource or at least one CSI-RS resource in the CSI resource configuration associated with the CSI report configuration, and on this basis, can further include at least one interference measurement resource or at least one RSSI measurement resource in the CSI resource configuration associated with the CSI report configuration. For details, see the description of the CSI resource in the first embodiment above, which will not be repeated here.

[0142] The Z' is the same as the Z' recorded in the first embodiment above, that is, the number of OFDM symbols required for calculating the beam measurement information. The Z' can be determined according to the BR i obtained in Table 1 recorded above, which will not be repeated here.

[0143] The x is an integer, wherein x=-1 represents a preceding OFDM symbol of a first OFDM symbol of the PUSCH or PUCCH in which the CSI report is configured, and an occupation time of the CSI processing unit starts from a first OFDM symbol of the CSI resource and ends at a preceding OFDM symbol of a period or a semi-persistent PUCCH or PUSCH in which the CSI report is configured.

[0144] x=0 represents the first OFDM symbol of the PUSCH or PUCCH in which the CSI report is configured, and the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource and ends at the first OFDM symbol of the period or the semi-persistent PUCCH or PUSCH in which the CSI report is configured.

[0145] x=1 represents a following OFDM symbol of the first OFDM symbol of the PUSCH or PUCCH in which the CSI report is configured, and the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource and ends at a following OFDM symbol of the first OFDM symbol of the period or the semi-persistent PUCCH or PUSCH in which the CSI report is configured.

[0146] ……, and so on.

[0147] In order to facilitate understanding of the occupation time of the CSI processing unit, x=-1 is taken as an example for illustration. Please refer to FIG. 5.

[0148] In FIG. 5, it is assumed that the subcarrier spacing of the terminal device is different from the subcarrier spacing of the network device, and each small square represents an OFDM symbol.

[0149] In the OFDM symbols of the downlink, the 2nd to 5th OFDM symbols from left to right are the OFDM symbols of the CSI resource, the CSI resource is the nearest CSI resource to the CSI resource transmitted for the last time from the preceding Z' OFDM symbols of the first OFDM symbol of the PUSCH or PUCCH in which the CSI report is configured, and the 7th and 8th OFDM symbols represent the OFDM symbols of the PDCCH used for triggering the CSI report.

[0150] In the OFDM symbols of the uplink, the 2nd and 3rd OFDM symbols from right to left are the OFDM symbols of the PUCCH or PUSCH in which the CSI report is configured.

[0151] As can be seen from FIG. 5, the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource and ends at the preceding OFDM symbol of the period or the semi-persistent PUCCH or PUSCH in which the CSI report is configured.

[0152] In general, when the CSI report is periodic or semi-persistent, and the network device has configured the physical uplink resource, the occupation time of the CSI processing unit starts from the first OFDM symbol of the latest transmitted CSI resource of the Z' OFDM symbol duration before the first symbol of the configured periodic or semi-persistent PUSCH / PUCCH (if present) to the first OFDM symbol of the periodic or semi-persistent PUSCH / PUCCH configured for the CSI report + x OFDM symbol position, or to the last OFDM symbol of the periodic or semi-persistent PUCCH / PUSCH configured for the CSI report, where x is an integer.

[0153] The CSI resource can also be the earliest CSI resource in the at least one CSI resource that is not later than the latest transmitted CSI reference resource corresponding to the CSI report. The CSI reference resource can be a reference resource defined in a related art standard, or can be related to a periodically or semi-persistently transmitted CSI-RS resource. When the CSI reference resource is related to a periodically or semi-persistently transmitted CSI-RS resource, the CSI reference resource can be the first OFDM symbol of the first CSI-RS resource in the at least one CSI-RS resource transmitted each time, or the last OFDM symbol of the last CSI-RS resource in the at least one CSI-RS resource transmitted each time.

[0154] For ease of understanding, reference can be made to FIG. 6.

[0155] In FIG. 6, it is assumed that the subcarrier spacing of the terminal device and the subcarrier spacing of the network device are different, and each small square represents an OFDM symbol.

[0156] As can be seen from FIG. 6, the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource to the last OFDM symbol of the PUCCH or PUSCH configured for the CSI report. The CSI resource is the CSI resource that is not later than the latest transmitted CSI reference resource corresponding to the CSI report, and the CSI reference resource is defined in relation to the CSI-RS resource transmitted each time.

[0157] In the second implementation, when the time domain feature of the CSI report is periodic or semi-persistent, and the network device has configured or has not configured the physical uplink resource, determining the occupation time of the CSI processing unit can include:

[0158] The occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource to the (Z'+y) OFDM symbols after the last OFDM symbol of the CSI resource.

[0159] The CSI resource can be the earliest CSI resource in at least one CSI resource of each transmission.

[0160] The CSI resource needs to include at least one SSB resource or at least one CSI-RS resource in the CSI resource configuration associated with the CSI report configuration, and can further include at least one interference measurement resource or at least one RSSI measurement resource in the CSI resource configuration associated with the CSI report configuration. For details, please refer to the description of the CSI resource in the first embodiment above, which will not be repeated here.

[0161] The Z' is the same as the Z' described in the first embodiment above, that is, the number of OFDM symbols required for calculating the beam measurement information. The Z' can be determined according to the BR in Table 1 described above. i The details are not repeated here.

[0162] The y is an integer greater than or equal to 0, where y = 0 represents Z' OFDM symbols after the last OFDM symbol of the CSI resource, and the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource and ends at the Z' OFDM symbols after the last OFDM symbol of the CSI resource.

[0163] y = 1 represents (Z' + 1) OFDM symbols after the last OFDM symbol of the CSI resource, and the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource and ends at the (Z' + 1) OFDM symbols after the last OFDM symbol of the CSI resource.

[0164] ……, and so on.

[0165] In order to facilitate the understanding of the occupation time of the CSI processing unit, y = 0 is taken as an example for illustration. Please refer to FIG. 7.

[0166] In FIG. 7, it is assumed that the subcarrier spacing of the terminal device is different from the subcarrier spacing of the network device, and each small square represents an OFDM symbol.

[0167] In the OFDM symbols of the downlink, the 2nd to 5th OFDM symbols from left to right are the OFDM symbols of the CSI resource of each transmission.

[0168] In the OFDM symbols of the uplink, when the network device configures the physical uplink resource, the 2nd and 3rd OFDM symbols from right to left are the OFDM symbols of the configured physical uplink resource, that is, the OFDM symbols of the PUCCH or PUSCH configured for the CSI report.

[0169] As can be seen from FIG. 7, the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource and ends Z' OFDM symbols after the last OFDM symbol of the CSI resource.

[0170] In general, when the CSI report is periodic or semi-persistent, and the network device has configured or has not configured a physical uplink resource, the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource of each transmission and ends Z' OFDM symbols after the last OFDM symbol of the CSI resource + y OFDM symbols, regardless of the physical uplink resource (i.e., PUCCH resource or PUSCH resource) configured for the CSI report.

[0171] The CSI resource can also be the earliest CSI resource in at least one CSI resource that is not later than the latest transmission of the CSI reference resource corresponding to the CSI report. The CSI reference resource is the same as the CSI reference resource described above, which will not be repeated here.

[0172] For ease of understanding, please refer to FIG. 8.

[0173] In FIG. 8, it is assumed that the subcarrier spacing of the terminal device and the subcarrier spacing of the network device are different, and each small square represents an OFDM symbol.

[0174] As can be seen from FIG. 8, the occupation time of the CSI processing unit starts from the first OFDM symbol of the CSI resource and ends Z' symbols after the last symbol of the CSI resource, where y = 0. The CSI resource is the CSI resource that is not later than the latest transmission of the CSI reference resource corresponding to the CSI report, and the CSI reference resource is the CSI reference resource defined in the standard of the related technology.

[0175] It should be noted that in the above two implementation manners, i.e., when the time domain feature of the CSI report is periodic or semi-persistent, the measurement period and the time slot offset of the CSI resource can be consistent with the transmission period and the time slot offset of the CSI report resource.

[0176] The CSI resource needs to include at least one SSB resource or at least one CSI-RS resource in the CSI resource configuration associated with the CSI report configuration, and can further include at least one interference measurement resource or at least one RSSI measurement resource in the CSI resource configuration associated with the CSI report configuration. After the network device configures the CSI resource related to the CSI report configuration for the terminal device, the measurement period and the slot offset of the terminal device on the CSI resource when performing beam measurement can be the same as the transmission period and the slot offset of the network device configuring the CSI resource, and the measurement period and the slot offset of the terminal device on the CSI resource do not need to be additionally specified.

[0177] In a third implementation manner, when the time domain feature of the CSI report is aperiodic and the network device has configured the physical uplink resource, determining the occupation time of the CSI processing unit can include:

[0178] The occupation time of the CSI processing unit starts from the first OFDM symbol after the PDCCH triggering the CSI report and ends at the last symbol of the PUSCH configured for the CSI report.

[0179] The PDCCH triggering the CSI report can include a DCI, and the CSI report is triggered by a CSI request field in the DCI.

[0180] The specific implementation of the embodiment can refer to the content described in the embodiments shown in FIG. 3 and FIG. 4, which will not be described again here.

[0181] In a fourth implementation manner, when the time domain feature of the CSI report is aperiodic and the network device has configured or has not configured the physical uplink resource, determining the occupation time of the CSI processing unit can include:

[0182] The occupation time of the CSI processing unit starts from the first OFDM symbol after the PDCCH triggering the CSI report and ends at one of the first OFDM symbol and the second OFDM symbol, or ends at the latest OFDM symbol of the first OFDM symbol and the second OFDM symbol plus y OFDM symbols.

[0183] The first OFDM symbol is Z OFDM symbols after the first OFDM symbol after the PDCCH triggering the CSI report, and the second OFDM symbol is Z' OFDM symbols after the last OFDM symbol in the CSI resource.

[0184] The CSI resource needs to include at least one SSB resource or at least one CSI-RS resource in the CSI resource configuration associated with the CSI report configuration, and can further include at least one interference measurement resource or at least one RSSI measurement resource in the CSI resource configuration associated with the CSI report configuration.

[0185] The Z' is the same as the Z' described in the first embodiment, that is, the number of symbols required for calculating the beam measurement information, and the Z' can be determined by the BR in Table 1 described above. i Obtained.

[0186] The Z is the same as the Z described in the first embodiment, that is, the Z is related to the Z', and the Z can be determined based on the Z' in combination with Table 2 and Table 3 described above.

[0187] The n is an integer greater than or equal to 0.

[0188] For ease of understanding, when the occupation time of the CSI processing unit starts from the first OFDM symbol after the PDCCH triggering the CSI report and ends at one of the first OFDM symbol and the second OFDM symbol, reference can be made to FIG. 9.

[0189] In FIG. 9, it is assumed that the subcarrier spacing of the terminal device is different from the subcarrier spacing of the network device, and each small square represents an OFDM symbol.

[0190] In the OFDM symbols of the downlink, the 2nd to 5th OFDM symbols from left to right are the OFDM symbols of the CSI resource transmitted once.

[0191] In the OFDM symbols of the uplink, when the network device has configured the physical uplink resource, the 2nd and 3rd OFDM symbols from right to left are the OFDM symbols of the configured physical uplink resource, that is, the OFDM symbols of the PUCCH or PUSCH configured for the CSI report.

[0192] As can be seen from FIG. 9, the occupation time of the CSI processing unit starts from the first OFDM symbol after the PDCCH triggering the CSI report and ends at the first OFDM symbol, that is, Z OFDM symbols after the PDCCH triggering the CSI report.

[0193] For ease of understanding, when the occupation time of the CSI processing unit starts from the first OFDM symbol after the PDCCH triggering the CSI report and ends at the latest OFDM symbol of the first OFDM symbol and the second OFDM symbol plus n OFDM symbols, reference can be made to FIG. 10.

[0194] In FIG. 10, it is assumed that n = 0, the subcarrier spacing of the terminal device is different from the subcarrier spacing of the network device, and each small square represents one OFDM symbol.

[0195] In the OFDM symbols of the downlink, the 2nd to 5th OFDM symbols from the left are the OFDM symbols of the CSI resource for one-time transmission.

[0196] In the OFDM symbols of the uplink, when the network device has configured the physical uplink resource, the 2nd and 3rd OFDM symbols from the right are the OFDM symbols of the configured physical uplink resource, i.e., the OFDM symbols of the PUCCH or PUSCH configured for CSI reporting.

[0197] As can be seen from FIG. 10, the occupation time of the CSI processing unit starts from the first OFDM symbol after the PDCCH triggering the CSI reporting, and ends at the later one of the first OFDM symbol and the second OFDM symbol, i.e., the Z' OFDM symbols after the last OFDM symbol in the CSI resource.

[0198] In general, when the CSI reporting is aperiodic and the network device has configured or has not configured the physical uplink resource, the occupation time of the CSI processing unit starts from the first symbol after the PDCCH triggering the CSI reporting, and ends at one or the later one of (1) the Z OFDM symbols after the first OFDM symbol after the PDCCH triggering the CSI reporting, and (2) the Z' OFDM symbols after the last OFDM symbol in the CSI resource, plus n OFDM symbols, where n = 0, 1, 2,....

[0199] It should be noted that in each of the above embodiments, the triggered reporting beam measurement information or the reported CSI information is the aperiodic CSI report with no content and the CSI-RS resource not used for TRS measurement. When one DCI triggers multiple aperiodic CSI reports, and one of the CSI reports is the aperiodic CSI report with no content and the CSI-RS resource not used for TRS measurement, Z or Z' is determined according to the rule for triggering multiple aperiodic CSI reports in the related art, i.e., Z = max(Z(m)), Z' = max(Z'(m)).

[0200] In one particular embodiment of the present disclosure, when the CSI report type is no content of beam measurement information reported to the network device and the CSI-RS resource is not used for TRS measurement, it can also be determined that the CSI processing unit is not occupied, i.e., the occupation time of the CSI processing unit is zero. In this case, other processing units in the terminal device can be used to calculate the CSI.

[0201] In the technical solution provided in the embodiments of the present disclosure, in the beam management, when determining the occupation time of the CSI processing unit in the terminal device, the occupation time of the CSI processing unit can be determined according to the CSI report type in the CSI report configuration, wherein the CSI report type includes that the CSI information reported by the terminal device to the network device is beam measurement information, or the CSI information reported by the terminal device to the network device is no content and the channel state information reference signal (CSI-RS) resource is not used for tracking reference signal (TRS) measurement. In this way, in the beam management, when the CSI information reported to the network device is beam measurement information and the reported CSI information is no content and the CSI-RS resource is not used for TRS measurement in two application scenarios, the occupation time of the CSI processing unit can be determined based on the technical solution provided in the embodiments of the present disclosure, and the behaviors of the terminal device and the network device are more clear.

[0202] FIG. 11 is a flowchart of a method for determining the occupation time of the channel state information (CSI) processing unit according to one embodiment of the present disclosure, which is applied to a terminal device, and the method is described as follows.

[0203] S112: When there is no CSI report configuration configured by the network device and there is a CSI-RS resource configuration configured by the network device, the occupation time of the CSI processing unit is determined according to the CSI-RS resource transmitted by the network device each time.

[0204] In the embodiments of the present disclosure, when the repetition setting in the CSI report configuration configured by the network device is turned on (i.e., repetition is “on”) and the time domain feature of the CSI-RS configured in the CSI-RS resource configuration is periodic CSI-RS, in this case, the terminal device can perform periodic beam measurement without CSI report, or the time domain feature of the CSI-RS resource configuration is semi-persistent CSI-RS and is activated, in this case, the terminal device can perform semi-persistent beam measurement without CSI report.

[0205] The terminal device determining the occupation time of the CSI processing unit according to the CSI-RS resource transmitted by the network device each time can include:

[0206] The occupation time of the CSI processing unit starts from the first OFDM symbol in the CSI-RS resource and ends at the (Z'+y)th OFDM symbol after the last OFDM symbol in the CSI-RS resource;

[0207] The Z' is the number of OFDM symbols required for calculating the beam measurement information, the y is an integer greater than or equal to 0, the CSI-RS resource is the earliest CSI-RS resource in at least one CSI-RS resource for each transmission, or the CSI-RS resource is the earliest CSI-RS resource in at least one CSI resource for the latest transmission of the CSI reference resource corresponding to the CSI report.

[0208] The CSI reference resource can be a reference resource defined in the standard of the related art, or can be related to a periodically or semi-persistently transmitted CSI-RS resource. When the CSI reference resource is related to a periodically or semi-persistently transmitted CSI-RS resource, the CSI reference resource can be the first OFDM symbol of the first CSI-RS resource in at least one CSI-RS resource for each transmission, or the last OFDM symbol of the last CSI-RS resource in at least one CSI-RS resource for each transmission.

[0209] For ease of understanding, refer to FIG. 12 and FIG. 13.

[0210] In FIG. 12, the occupation time of the CSI processing unit can start from the first OFDM symbol in the CSI resource (a set of CSI resources in the CSI resource configuration for each transmission) and end at the Z'th OFDM symbol after the last OFDM symbol of the last CSI-RS resource for this transmission, where y=0, and the definition of Z' can be the same as the Z' described in the embodiment shown in FIG. 1 above, but in the embodiment of the present disclosure, Z' is determined by Table 4 and Table 5 as follows.

[0211] Table 4

[0212]

[0213] Table 5

[0214]

[0215] It should be noted that the period of the beam measurement without CSI reporting performed by the terminal device and the time slot offset can be consistent with the period of the periodic CSI-RS or the period and time slot offset of the semi-persistent CSI-RS configured in the CSI resource configuration, that is, the UE can perform the beam measurement without CSI reporting once every time a set of CSI-RS resources in the CSI-RS resource set in the CSI resource configuration is transmitted and the repetition is set to "on", and the beam measurement period and time slot offset of the CSI reporting are consistent with the transmission period and time slot offset of the periodic or semi-persistent CSI-RS resource.

[0216] The technical solution provided by the embodiments of the present disclosure can be used to determine the occupation time of the CSI processing unit in the terminal device in the application scenario without configuring the CSI reporting configuration in the beam management, and the occupation time of the CSI processing unit is clear, and the behaviors of the terminal device and the network device are more clear.

[0217] The embodiments of the present disclosure also provide a method for determining PUCCH target reception power, please refer to FIG. 14.

[0218] FIG. 14 is a flowchart of a method for determining PUCCH target reception power according to an embodiment of the present disclosure. The method is described as follows.

[0219] In the time period from when the terminal device successfully receives the link recovery response from the network device to when the terminal device successfully receives the MAC CE activation or the radio resource control (RRC) reconfiguration signaling related to the PUCCH spatial related information in the link recovery process, when the spatial filtering parameter used for the PUCCH transmission is the same as the physical random access channel (PRACH) and the PRACH is the contention-based PRACH, the target reception power of the PUCCH is determined according to the cell-level configured target reception power and the terminal device specific target reception power.

[0220] In the embodiments of the present disclosure, the link recovery process can also be understood as the beam failure recovery process, the link recovery can also be understood as the beam failure recovery, the spatial filtering parameter used for the PUCCH transmission can also be understood as the beam used for the PUCCH transmission, and the cell-level configured target reception power can be represented as P O_NOMINAL_PUCCH , and the terminal device specific target reception power can be represented as P O_UE_PUCCH .

[0221] When the PUCCH target reception power is determined according to the cell-level configured target reception power and the terminal device specific target reception power, the sum of the cell-level configured target reception power and the terminal device specific target reception power can be used as the target reception power of the PUCCH.

[0222] In the embodiments of the present disclosure, P O_UE_PUCCH may be 0; P O_NOMINAL_PUCCH may be the value of the higher layer configuration parameter cell level target received power p0-nominal.

[0223] In an implementation manner, if the higher layer does not configure p0-nominal, P O_NOMINAL_PUCCH may be 0 by default;

[0224] In an implementation manner, if the higher layer does not configure p0-nominal, P O_NOMINAL_PUCCH may be the sum of the preamble target received power and the offset of the message 3 and the preamble target received power, and can be specifically represented by the following formula:

[0225] P O_NOMINAL_PUSCH,f,c (0)=P O_PRE +Δ PREAMBLE_Msg3 ;

[0226] wherein, P O_PRE represents the preamble target received power preambleReceivedTargetPower, and Δ PREAMBLE_Msg3 represents the message 3 offset msg3-DeltaPreamble; both preambleReceivedTargetPower and msg3-DeltaPreamble are configured by the higher layer.

[0227] In the embodiments of the present disclosure, after the terminal device successfully receives the link recovery response from the network device, and before the terminal device successfully receives the PUCCH spatial related information MAC CE activation or RRC reconfiguration, when the spatial filtering parameter used by the PUCCH transmission is the same as the PRACH, and the PRACH is a contention-based PRACH, the target received power of the PUCCH can be determined according to the cell level configured target received power and the terminal device specific target received power.
