Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and more particularly, to a method and apparatus for determining an occupation time of a channel state information processing unit. BACKGROUND

[0002] When performing channel state information (CSI) calculation, a terminal device occupies some processing units of the terminal device, which can be referred to as CSI processing units (CPUs). At present, the occupation time of the CPUs is determined according to the reporting time of the CSI. However, in some scenarios, a network device is not aware of the time of CSI reporting, and thus cannot reasonably determine the occupation time of the CPUs.

[0003] Therefore, how to reasonably determine the occupation time of the CPUs is a problem to be solved. SUMMARY

[0004] The present application provides a method and apparatus for determining an occupation time of a channel state information processing unit, which can reasonably determine the occupation time of the CPUs.

[0005] In a first aspect, a method for determining an occupation time of a channel state information (CSI) processing unit (CPU) is provided. The execution subject of the method provided in the first aspect can be a first apparatus. In the absence of special description, the first apparatus in the present application can refer to the first apparatus itself (for example, a terminal device), or can refer to a component (for example, a processor, a chip, or a chip system, etc.) in the first apparatus, or can be a logic module or software that can realize all or part of the functions of the first apparatus. For ease of description, the first apparatus is taken as an example in the following description.

[0006] For example, the chip can be a Modem chip, also known as a baseband chip. For another example, the chip can be a system on chip (SoC) chip or a system in package (SIP) chip including a modem core.

[0007] The method comprises: receiving configuration information, the configuration information being used to determine a measurement resource corresponding to a CSI report; and determining, according to the measurement resource and / or a first period, an occupation time of a CPU by the first device processing the CSI report, the occupation time of the CPU being a time during which the CPU is occupied by the first device processing the CSI report, wherein the first period is a measurement resource period of the measurement resource, or the first period comprises a time interval between a first sending occasion and a second sending occasion, the first sending occasion and the second sending occasion being two adjacent sending occasions in a first resource, the measurement resource being located in the first period in a time domain, and the first resource being used to send information related to the CSI report.

[0008] The first period comprises a time interval between a first sending occasion and a second sending occasion, and it can be understood that the first period can be a period of the first resource.

[0009] Based on the above scheme, in the process of determining the occupation time of the CPU corresponding to the CSI report, the first device can consider the measurement resource related to the CSI report, the measurement resource period of the measurement resource, or the period of the first resource, so as to reasonably determine the occupation time of the CPU. Therefore, the above scheme can enable the network device to reasonably configure measurement of a reference signal measurement resource and reporting of a CSI, so that the first device efficiently utilizes the CPU and reduces conflicts in CSI reporting.

[0010] In some implementations, the configuration information is used to indicate that there is a reporting amount of the CSI report, and / or the sending of the CSI report is event-triggered or initiated by the first device.

[0011] Based on the above scheme, in the case of event-triggered reporting, first-device-initiated reporting, or a reporting amount, the first device can reasonably determine the occupation time of the CPU according to the measurement resource related to the CSI report, the measurement resource period of the measurement resource, or the period of the first resource.

[0012] In some implementations, the first resource is a first indication resource or a first reporting resource, the first indication resource is used to send first information, and the first reporting resource is used to send the CSI report; the first information is used to indicate that a fourth sending occasion associated with a third sending occasion exists the CSI report, or whether the fourth sending occasion associated with the third sending occasion exists the CSI report, wherein the third sending occasion is a sending occasion of the first information in the first indication resource, and the fourth sending occasion is a sending occasion in the first reporting resource; or the first resource is a first indication resource, and the first indication resource is used to send first information, the first information being used to request a resource for scheduling the CSI report (or the first information being used to request a resource for the CSI report).

[0013] Based on the above scheme, the first resource can be a resource for indication or a resource for reporting. In this way, the first device can consider the period of the indicated resource or the period of the resource for reporting in determining the CPU occupation time, so as to more reasonably determine the CPU occupation time.

[0014] In some implementations, in a case where the first device sends the first information and the first information is used to request scheduling of a resource for the CSI report, the method further includes: receiving second information, the second information being used to indicate a second reporting resource for sending the CSI report.

[0015] Based on the above scheme, in a case where the first device requests scheduling of a resource for the CSI report, the second device can indicate the resource for the CSI report, so as to enable the first device to perform the CSI report.

[0016] In some implementations, the first period is a measurement resource period of the measurement resource, wherein a start point of the CPU occupation time is a first time domain unit of the measurement resource in the first period, and an end point of the CPU occupation time is a last time domain unit of the measurement resource in the first period plus a first duration.

[0017] In the alternative expression 1, the CPU occupation time includes: from a first time domain unit of a measurement resource in a first period, to a last time domain unit of the measurement resource in the first period, and a first duration after the last time domain unit of the measurement resource in the first period.

[0018] In the alternative expression 2, the CPU occupation time includes: from a first time domain unit of a first measurement resource in a first period until a first duration after a last time domain unit of the first measurement resource in the first period.

[0019] For example, if the time domain unit is a symbol, the first time length is K symbols (K is an integer greater than or equal to 0), and the measurement resource is a channel state information reference signal (CSI-RS) / SSB resource in each measurement period (i.e., the first period, or in other words, the measurement resource period of the measurement resource). Wherein the measurement period can be replaced by the transmission occasion. Then, the CPU occupation time can include: from the first symbol of the earliest CSI-RS / SSB resource in each transmission occasion, to K symbols after the last symbol of the latest CSI-RS / SSB resource in each transmission occasion.

[0020] In alternative expression 3, the CPU occupation time is a third time length, which is the time length from the first time domain unit of the measurement resource in the first period to the last time domain unit of the measurement resource in the first period; or the third time length is the time length after the first time domain unit of the measurement resource in the first period to the last time domain unit of the measurement resource in the first period.

[0021] In alternative expression 4, the CPU occupation time is the first symbol of the earliest one of the periodic or semi-persistent CSI-RS / SSB resources for event monitoring measurement in each first period (or transmission occasion), and the first symbol after the last symbol of the periodic or semi-persistent CSI-RS / SSB resources for event monitoring measurement in each first period (or transmission occasion).

[0022] Based on the above scheme, the CPU occupation time determined by the first device is short, and the time for processing CSI is saved.

[0023] In some implementations, the measurement resource is located in the first period in the time domain, the first period includes a time interval between the first transmission occasion and the second transmission occasion, wherein the starting point of the CPU occupation time is the first time domain unit of the measurement resource, and the ending point of the CPU occupation time is the last time domain unit of the measurement resource plus the first time length.

[0024] The occupation time of the CPU includes: from the first time domain unit of the measurement resource in the first period, to the last time domain unit of the measurement resource in the first period, and a first duration after the last time domain unit of the measurement resource in the first period.

[0025] The occupation time of the CPU includes: from the first time domain unit of the measurement resource in the first period, to the last time domain unit of the measurement resource in the first period, and a first duration after the last time domain unit of the measurement resource in the first period.

[0026] For example, if the time domain unit is a symbol, the first duration is K symbols (K is an integer greater than or equal to 0), and the measurement resource is a CSI-RS / SSB resource in each first period (i.e., the period of the first indication resource, or the period of the first reporting resource). Wherein, the first period can be replaced by the transmission occasion. Then, the occupation time of the CPU can include: from the first symbol of the earliest CSI-RS / SSB resource of each transmission occasion, to K symbols after the last symbol of the latest CSI-RS / SSB resource in each transmission occasion (from the first symbol of the earliest one of each transmission occasion of CSI-RS / SSB resource, until K symbols after the last symbol of the latest one of the CSI-RS / SSB resource in each transmission occasion).

[0027] The occupation time of the CPU is a third duration, which is the duration from the first time domain unit of the measurement resource in the first period to the last time domain unit of the measurement resource in the first period; or the third duration is the duration after the first time domain unit of the measurement resource in the first period to the last time domain unit of the measurement resource in the first period.

[0028] In the alternative expression 4, the CPU occupation time is from the beginning of the first symbol of the periodic or semi-persistent CSI-RS / SSB resource used for event monitoring measurement in each first resource to the first duration after the last symbol of the periodic or semi-persistent CSI-RS / SSB resource (not later than the corresponding CSI reference resource) used for event monitoring measurement in each first resource. The first resource can be the first indication resource or the first reporting resource.

[0029] Based on the above scheme, the first device can determine the CPU occupation time according to the measurement resource, and the implementation is simple.

[0030] In some implementations, the measurement resource is located in the first period in the time domain, the first period includes a time interval between the first transmission occasion and the second transmission occasion, and the last measurement resource period in at least one measurement resource period of the measurement resource is the second period. The start point of the CPU occupation time is the first time domain unit of the measurement resource in the second period, the end point of the CPU occupation time is the last time domain unit of the measurement resource in the second period, and the first duration is added.

[0031] For example, the first period can include at least one second period.

[0032] In the alternative expression 1, the CPU occupation time includes: from the first time domain unit of the measurement resource in the second period to the last time domain unit of the measurement resource in the second period, and the first duration after the last time domain unit of the measurement resource in the second period. Or, from the first time domain unit of the measurement resource in the second period to the last time domain unit of the measurement resource (or the second period), and the first duration after the last time domain unit of the measurement resource (or the second period).

[0033] In the second alternative, the CPU occupation time includes: from the first time domain unit of a first measurement resource in a second period until a first duration after the last time domain unit of the first measurement resource in the second period. Or, from the first time domain unit of a first measurement resource in a second period until a first duration after the last time domain unit of the first measurement resource [or the second period].

[0034] For example, if the time domain unit is a symbol, the first duration is K symbols (K is an integer greater than or equal to 0), and the measurement resource is a CSI-RS / SSB resource in each second period. Wherein, the second period can be replaced by a transmission occasion. Then, the CPU occupation time can include: from the first symbol of the earliest CSI-RS / SSB resource of each transmission occasion, until K symbols after the last symbol of the latest CSI-RS / SSB resource in each transmission occasion.

[0035] In an alternative expression 3, the CPU occupation time is a third duration, which is a duration from a first time domain unit of the measurement resource in the second period to a last time domain unit of the measurement resource in the second period, or a duration from a first time domain unit of the measurement resource in the second period to a time after the last time domain unit of the measurement resource in the second period. Alternatively, the third duration is a duration from a first time domain unit of the measurement resource in the second period to a last time domain unit of the measurement resource (or the second period), or a duration from a first time domain unit of the measurement resource in the second period to a time after the last time domain unit of the measurement resource (or the second period).

[0036] In an alternative expression 4, the CPU occupation time is a duration from a beginning of a first symbol of a period or a semi-persistent CSI-RS / SSB resource for event monitoring measurement in a nearest measurement resource period (i.e., the second period) before a transmission occasion of each first resource to a first duration after a last symbol of the period or the semi-persistent CSI-RS / SSB resource for event monitoring measurement in each second period (not later than a CSI reference resource).

[0037] In an alternative expression 5, the CPU occupation time is a duration from a beginning of a first symbol of a period or a semi-persistent CSI-RS / SSB resource for event monitoring measurement in a nearest measurement resource period (i.e., the second period) before a transmission occasion of each first resource and not later than a corresponding CSI reference resource to a first duration after a last symbol of the period or the semi-persistent CSI-RS / SSB resource for event monitoring measurement in each second period.

[0043] In the alternative expression 4, the CPU occupation time is from the beginning of the earliest one of the periodic or semi-persistent CSI-RS / SSB resources for event monitoring measurement in the latest measurement resource period (i.e., a second period) before the transmission occasion of each first resource, to the last symbol of the first resource in each first period, or the last symbol of the first resource in each first period plus a first duration.

[0058] In the alternative expression 5, the CPU occupation time is the start of the earliest one of the measurement resource periods (i.e., the second period) for event monitoring measurement or the first symbol of the semi-persistent CSI-RS / SSB resource before the sending time of the first resource in the first period, until the first duration after the last symbol of the scheduled reporting resource.

[0134] In the present application, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. In the textual description of the present application, the character " / " generally represents an "or" relationship between the front and rear associated objects. "At least one of the following" or similar expressions means any combination of these items, including any combination of single item or multiple items. For example, at least one of a, b and c can represent: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c. Where a, b and c can be single or multiple.

[0135] In the present application, "first", "second", and various numerical numbers (for example, #1, #2, etc.) indicate the differentiation for the convenience of description, and are not used to limit the scope of the embodiments of the present application. For example, to distinguish different messages, etc., rather than to describe a specific order or sequence. It should be understood that the objects thus described can be interchanged under appropriate circumstances, so as to be able to describe schemes other than the embodiments of the present application.

[0136] In the present application, "when", "in the case of", "if" and the like all refer to the objective situation in which the device will make corresponding processing, and are not limited to time, and do not require the device to have a judgment action when implemented, nor does it mean that there are other limitations.

[0137] In the present application, "indicate" or "for indicating" can include direct indication and indirect indication. When describing that certain indication information is used to indicate A, it can include that the indication information directly indicates A or indirectly indicates A, and it does not mean that A must be carried in the indication information.

[0138] The indication manner involved in the embodiments of the present application should be understood as covering various methods that can enable the to-be-indicated party to know the to-be-indicated information. The to-be-indicated information can be sent as a whole, or can be sent separately in multiple sub-information, and the sending period and / or sending opportunity of these sub-information can be the same or different, and the present application does not limit the sending method.

[0139] The "indication information" in the embodiments of the present application can be explicit indication, that is, directly indicated through signaling, or obtained according to the parameters indicated by the signaling, combined with other rules or combined with other parameters or through derivation. It can also be implicit indication, that is, obtained according to rules or relationships, or according to other parameters, or through derivation. The present application does not make specific limitations on this.

[0140] In this application, "protocol" can refer to a standard protocol in the field of communications, such as 5G (5G) protocols. th This application does not limit the scope of protocols such as generation (5G), new radio (NR), and related protocols applied in future communication systems. "Predefined" may include predefined terms, such as protocol definitions.

[0141] In this application, "communication" can also be described as "data transmission," "information transmission," "data processing," etc. "Transmission" includes "sending" and "receiving." For example, transmission can be uplink transmission, such as a terminal device sending a signal to a network device; transmission can also be downlink transmission, such as a network device sending a signal to a terminal device; transmission can also be sidelink transmission, such as a terminal device sending a signal to another terminal device. For example, "transmission" can be air interface level transmission, or it can be signal transmission from a chip input (I) / output (O) port, rather than air interface level transmission.

[0142] In this application, terms such as "message," "information," "signal," or "information element (IE)" can be used interchangeably. There are no restrictions on the name of the message or information, as long as it can achieve the corresponding function.

[0143] "Sending information to XX (device)" can be understood as the destination of the information being that device. This can include sending information directly or indirectly to that device. "Receiving information from XX (device), or receiving information from XX (device)" can be understood as the source of the information being that device. This can include receiving information directly or indirectly from that device. Information may undergo necessary processing between the source and destination, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood in a similar way, and will not be repeated here. Furthermore, "sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, "sending" or "receiving" can occur between devices, for example, between network devices and terminal devices via an air interface. "Sending" or "receiving" can also occur within a device, for example, between components, modules, chips, software modules, or hardware modules within the device via a bus, wiring, or interface.

[0144] In this application, the words "exemplary," "for example," and the like are used to mean serving as an example, instance, or illustration, in order to convey the general principle. Any implementation described in this application as "exemplary" or "for example" is not necessarily to be construed as preferred or advantageous over other implementations. In the application, "of", "corresponding", "corresponding" and "associated" are sometimes mixed, it should be pointed out that when there is no emphasis on their differences, the meanings expressed are consistent.

[0145] In this application, the configuration can be signaling configuration, or described as configuration signaling. For example, the signaling configuration includes the configuration by the signaling sent by the network device, which can be radio resource control (RRC) message, DCI, or system information block (SIB). For another example, the signaling configuration includes the configuration between network devices. Among them, the network device can include access network device, core network device, or management plane device, etc. Optionally, the signaling configuration can also be configured to the terminal device or network device by preconfigured signaling, or configured to the terminal device or network device by preconfigured way. Here, the preconfiguration is to define or configure the value of the corresponding parameter in advance in the protocol, and store it in the terminal device or network device when communicating with the terminal device or network device. The preconfigured message can be modified or updated under the condition that the terminal device or network device is connected to the network.

Those skilled in the art can know that the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems as new service scenarios appear.

[0148] In various embodiments of the present application, the size of the serial number of each process does not mean the order of execution, and the execution order of each process should be determined by its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application. The terms "include", "contain", "have" and their variants mean "include but not limited to", unless otherwise specifically emphasized.

[0149] For the convenience of understanding the embodiments of the present application, first, exemplary and simple introduction is made to the concepts that the embodiments can involve.

[0150] 1、beam: beam is a kind of communication resource.

[0151] Beam can also be referred to as spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL assumption, or QCL indication, etc.

[0152] Beam can be indicated by transmission configuration indicator state (TCI-state) parameter, or indicated by spatial relation parameter.

[0153] In the embodiments of the present application, beam can be replaced by spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (for example, including uplink TCI-state and downlink TCI-state), or spatial relation, etc. The above terms are also equivalent to each other. Beam can also be replaced by other terms representing beam, which are not limited herein.

[0154] Beam used for transmitting signal can be referred to as transmission beam (Tx beam), spatial domain transmission filter, spatial transmission filter, spatial domain transmission parameter, spatial transmission parameter, spatial domain transmission setting, or spatial transmission setting.

[0155] The downlink transmission beam can be indicated by a TCI-state, a channel state information reference signal (CSI-RS), a synchronization signal / physical broadcast channel block (SS / PBCH block). Among them, the SS / PBCH block can be referred to as a synchronization signal block (SSB).

[0156] In the embodiments of the present application, the downlink beam, the CSI-RS, the TCI-state, the downlink / joint TCI state (DLorjointTCI state), the SSB, and the tracking reference signal (TRS) can be replaced with each other.

[0157] The beam for receiving a signal can be referred to as a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. The uplink transmission beam can be indicated by any one of a spatial relationship, an uplink TCI-state, a sounding reference signal (SRS) resource (indicating a transmission beam using the SRS), a CSI-RS, an SSB, or a TRS. In the embodiments of the present application, the uplink beam, the uplink (UL) TCI-state, the DLorjointTCI state, the SRS, the CSI-RS, the SSB, and the TRS can be replaced with each other.

[0158] The transmission beam can refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna, and the reception beam can refer to the distribution of signal strength in different directions in space of the wireless signal received by the antenna.

[0159] In addition, the beam can be a wide beam, or a narrow beam, or other types of beams, and the beam forming technology can be beam forming technology or other technical means. The beam forming technology can be digital beam forming technology, analog beam forming technology, and hybrid digital / analog beam forming technology. Different beams can be considered as different resources.

[0160] For example, the beam can correspond to a resource, for example, when performing beam measurement, the network device can measure different beams through different resources. The terminal device can feed back the quality of the measured resource, so that the network device knows the quality of the corresponding beam. When data transmission, the beam information can also be indicated through its corresponding resource. For example, the network device indicates the information of the physical downlink shared channel (PDSCH) beam of the terminal device through the TCI field in the DCI.

[0161] In a possible implementation, multiple beams with the same or similar communication characteristics can be considered as one beam. One beam can include one or more antenna ports for transmitting data channels, control channels, and sounding signals, etc. One or more antenna ports forming a beam can also be regarded as an antenna port set.

[0162] 2, TCI: TCI can also be referred to as TCI state.

[0163] In uplink and downlink transmission, the network device and the terminal device both use the correct beam to achieve correct transmission. In downlink transmission, the network device can indicate the downlink transmission beam used by the network device to the terminal device. The terminal device can determine a suitable receiving beam according to the downlink transmission beam, which can be used to receive information from the network device. In uplink transmission, the network device also needs to indicate to the terminal device which uplink transmission beam to use to send information to the network device. The network device can determine the uplink transmission beam with better signal quality of the terminal device.

[0164] The uplink transmission beam and the downlink transmission beam can be indicated by the corresponding TCI state. Specifically, the downlink transmission beam can be indicated by the downlink TCI state, and the uplink transmission beam can be indicated by the uplink TCI state.

[0165] The network device can indicate the TCI state to the terminal device through the TCI field in the DCI. Exemplarily, the size of the TCI field can be 3 bits, which can be specifically represented as 8 different field values (codepoints). Each field value of the TCI field can be associated with an index of a TCI state. The index of the TCI state can uniquely identify a TCI state, which can be a downlink TCI state or an uplink TCI state. Each field value of the TCI field can also be associated with two TCI state indexes, which can uniquely identify two TCI states, which can include a downlink TCI state and an uplink TCI state.

[0166] The downlink TCI state can include several parameters, and the terminal device can determine the related information of the downlink transmission beam through these parameters, so as to determine to use a suitable receiving beam to receive information from the network device. The downlink TCI state can be configured by the network device to each terminal device, and the structure of the downlink TCI state is as follows:

[0167] TCI-State::= SEQUENCE{

[0168] Tci-StateId TCI-StateId,

[0169] qcl-Type1 QCL-Info,

[0170]

[0171] Each TCI state can include its own index (tci-StateId) and two quasi-colocation information (QCL-info). Each QCL-Info can include a cell field and a bandwidth part (bwp)-identifier (Id), which respectively represent which bwp of which cell (cell) the TCI-state applies to, that is, different cells or different bwp of the same cell can configure different QCL-Info. Each QCL-info can also include a referenceSignal, which is used to represent which reference signal resource forms a QCL relationship.

[0172] In R15 / R16 protocol, the term "beam" does not appear directly, and beams are usually replaced by other terms. For example, in data transmission and channel measurement, beams are corresponding to reference signal resources, and one beam corresponds to one reference signal resource. Therefore, it is essentially referred to which beam forms a QCL relationship when it is said to form a QCL relationship with which reference signal resource. The QCL relationship refers to two reference signal resources (or two antenna ports, where the antenna port and the reference signal resource can be one-to-one) having certain same spatial parameters. Which spatial parameters are the same depends on the type of the QCL-Info, i.e. another field qcl-Type of the QCL-Info. The qcl-Type can have four values {typeA, typeB, typeC, typeD}. Taking typeD as an example, typeD can represent that two reference signal resources have the same spatial reception parameter information, i.e. two beams have the same receiving beam. There can be at most one TypeD (or written as typeD) in the two QCL-Info included in the TCI-state.

[0173] Exemplarily, the network device can indicate a certain downlink TCI state for the terminal device through DCI. The terminal device can determine the reference signal resource in the typeD QCL information in the downlink TCI state. The terminal device can take the receiving beam of the reference signal resource as the receiving beam for downlink transmission.

[0174] Exemplarily, the receiving beam of the reference signal resource can be obtained by the terminal device in advance through the beam management process. For example, through the beam management process, the terminal device can determine which receiving beam is the best to receive the reference signal resource, and take the receiving beam as the receiving beam of the reference signal resource.

[0175] The following is a specific example to illustrate how the network device based on R15 / R16 protocol indicates the receiving beam information of the data transmission beam to the terminal device through TCI-state. The above process can include the configuration, activation and indication of TCI-state.

[0176] TCI-state configuration: the network device configures multiple TCI-states for the terminal device through RRC signaling. These TCI-states all include a typeD QCL-Info. The network device can also configure TCI-states that do not include typeD QCL-info, but these TCI-states are not used for data transmission beam indication, so they are not further described here.

[0177] TCI-state activation: After the network device configures multiple TCI-states, it can activate 8 of them through a media access control control element (MAC CE or MAC-CE). The 8 TCI-states are one-to-one corresponding to the 8 field values of the TCI field in the DCI. That is, which 8 TCI-states correspond to the 8 field values of the TCI field in the DCI is determined by the MAC CE.

[0178] TCI state indication: The network device can indicate a specific TCI-state through the TCI field in the DCI. For example, the field value of the TCI field in the DCI sent by the network device to the terminal device can be 000. "000" can represent that the data transmission beam adopts the TCI state corresponding to 000. The reference signal contained in the typeD QCL-Info in the TCI state can be a CSI-RS with index #1, indicating that the data transmission adopts the same receiving beam as the CSI-RS with index #1. The receiving beam corresponding to the CSI-RS with index #1 can be determined through a beam measurement process and is known to the terminal device. Therefore, through the specific value of the TCI field, the terminal device can determine the beam corresponding to the data transmission beam, and thus use the corresponding beam to send or receive data.

[0179] The three description methods of TCI state, TCI-state and TCI state in this application can be replaced with each other.

[0180] 3、Spatial relation

[0181] Exemplarily, the transmission beam of uplink transmission can be indicated by spatial relation. The function of spatial relation can be similar to that of TCI-state, which is used to inform the terminal device to use which transmission beam to perform uplink transmission.

[0182] Exemplarily, the spatial relation can be configured by RRC signaling. The information configuring the spatial relation can include an identification (id) of the spatial relation, a serving cell id, a target reference signal, a loss measurement reference signal, or a power control parameter, etc. Among them, the target reference signal (e.g., SRS, SSB, or CSI-RS) can be used to indicate the corresponding uplink beam. Exemplarily, assuming that the uplink transmission adopts spatial relation #1, which includes target reference signal #2, it can be represented that the transmission beam used for the uplink transmission is the transmission / reception beam of the target reference signal. For example, the target reference signal is SRS, which can represent that the transmission beam used for the uplink transmission is the transmission beam of the SRS (the transmission beam of the SRS is known). For another example, the target reference signal is SSB or CSI-RS, which can represent that the transmission beam used for the uplink transmission is the reception beam of the SSB or CSI-RS (the reception beam of the SSB / CSI-RS is known).

[0183] The network device can configure multiple spatial relations for the terminal device. Then one of them is activated by MAC CE for corresponding data transmission. The uplink transmission can include physical uplink control channel (PUCCH), SRS, or physical uplink shared channel (PUSCH), etc. For example, the spatial relation of PUCCH can be indicated by MAC-CE signaling. For another example, the spatial relation of SRS can be indicated by MAC-CE signaling. For another example, PUSCH can be associated with a specific SRS, and the spatial relation of the SRS is used for transmission.

[0184] 4、Unified TCI

[0185] The unified TCI can be a unified beam indication framework. For example, the network device can indicate a beam for the terminal device, which can be used for multiple channels and / or reference signals at the same time, and the beam can also be called a common beam. The common beam can be an uplink common beam, a downlink common beam, or an uplink and downlink common beam, which can be used by the terminal device in subsequent transmission.

[0186] The network device can indicate one uplink common beam for the terminal device to transmit multiple uplink channels and / or uplink reference signals, can indicate one downlink common beam for the terminal device to transmit multiple downlink channels and / or downlink reference signals, or can indicate one uplink and downlink common beam for the terminal device to transmit multiple uplink channels and / or uplink reference signals and multiple downlink channels and / or downlink reference signals. That is, the uplink and downlink common beam can be used for uplink transmission or downlink transmission.

[0187] In the embodiments of the present application, the beam can include the common beam.

[0188] 5、Resource

[0189] In the communication protocol, the reference signal can be configured in the form of a resource. The network device can configure each reference signal in the form of a resource to the terminal device, and one resource is one configuration information unit. The configuration information unit can include parameters related to the reference signal, such as the time-frequency resource position of the reference signal, the number of ports, the time domain type (periodic / semi-static / non-periodic), and the like.

[0190] The resource can be an uplink signal resource or a downlink signal resource. The uplink signal includes but is not limited to SRS or demodulation reference signal (DMRS). The downlink signal includes but is not limited to: CSI-RS, cell-specific reference signal (CS-RS), user equipment-specific reference signal (US-RS), DMRS, and synchronization signal / physical broadcast channel block (SS / PBCH block). The SS / PBCH block can be referred to as a synchronization signal block (SSB) for short.

[0191] 6、Reference signal

[0192] The reference signal can be the reference signal of the serving cell. For example, the serving cell can be a primary cell (Pcell), a secondary cell (Scell), or a primary secondary cell (PScell). Among them, the Pcell can be called a cell with a primary component carrier (PCC), and the Scell ​​can be called a cell with a secondary component carrier (SCC).

[0193] The reference signal can be the reference signal of the neighboring cell of the serving cell (such as the reference signal of the cell corresponding to the additional physical cell identifier (PCI)).

[0194] The reference signal can also be a reference signal associated with the handover candidate cell configuration. The handover candidate cell can also be called a candidate cell or a neighboring cell. The handover candidate cell can be the current serving cell or a non-serving cell. The PCI of the handover candidate cell is different from that of the current primary cell (PCell).

[0195] The terminal device can be configured with one or more candidate cells. The configuration of each candidate cell can include the configuration of reference signal resources, which can be SSB or CSI-RS.

These core network devices and network devices can be independent physical devices, or they can integrate the functions of the core network devices and the logical functions of the network devices onto the same physical device. Alternatively, a single physical device can integrate some core network device functions and some network device functions. Terminal devices and network devices can be interconnected via wired or wireless means. Wireless communication between terminal devices, between network devices, and between terminal devices and network devices can occur through air interface resources.

The terminal device can also be other devices with terminal functions, for example, the terminal device can also be a device in device to device (D2D) communication that assumes a terminal function. The embodiments of the present application are not limited in this regard.

[0204] In the embodiments of the present application, the device for implementing the function of the terminal device can be a terminal device, or a device capable of supporting the terminal device to implement the function, such as a chip or a chip system, which can be installed in the terminal device. The chip system can be composed of a chip, or can include a chip and other discrete devices. In the technical solutions of the embodiments of the present application, the device for implementing the function of the terminal device is taken as an example of the terminal device. The terminal device can also be referred to as a terminal. The following can take the terminal device as an example of the UE to describe the technical solutions provided by the embodiments of the present application.

[0205] The roles of the base station and the terminal can be relative, for example, Figure 1The helicopter or unmanned aerial vehicle 112i in the figure can be configured as a mobile base station, and for those terminals 112j accessing the wireless access network 110 through 112i, 112i is the base station; but for the base station 111a, 112i is a terminal, that is, 111a communicates with 112i through a wireless air interface protocol. Of course, 111a and 112i can also communicate through a base station-to-base station interface protocol, in which case 112i is also a base station relative to 111a. Therefore, both base stations and terminals can be collectively referred to as communication devices, Figure 1 111a and 111b in the figure can be referred to as communication devices with base station functions, Figure 1 112a-112j in the figure can be referred to as communication devices with terminal functions.

[0206] The network device and the terminal device can communicate through a wireless link. The transmission link from the network device to the terminal device can be referred to as a downlink (DL) or a downlink channel, used to transmit a downlink signal. The transmission link from the terminal device to the network device can be referred to as an uplink (UL) or an uplink channel, used to transmit an uplink signal. The transmission link from the terminal device to the terminal device can be referred to as a sidelink (SL) or a sidelink channel. In the embodiments of the present application, multiple network devices can send information to multiple different terminal devices and receive information from multiple different terminal devices; multiple network devices can also send information to the same terminal device and receive information from the same terminal device, which is not limited in the present application.

[0207] The communication between different devices involved in the embodiments of the present application can mean direct communication between different devices (i.e. without the need for other devices to relay or forward), or can mean communication between different devices through other devices (i.e. with the need for other devices to relay or forward), or can mean that a functional unit inside a device communicates with other devices through another functional unit. The information between the source and the destination of the information transmission can be processed as necessary, such as format change, digital-to-analog conversion, amplification, or filtering, etc., but the destination can understand the valid information from the source. Similar expressions in the present application can be understood similarly, and will not be repeated here.

Exemplarily, the transceiver 213 can include a transmitter 2131, a receiver 2132, and an antenna 2133. The network device 220 can include a processor 221, a memory 222, and a transceiver 223. Exemplarily, the transceiver 223 can include a transmitter 2231, a receiver 2232, and an antenna 2233. The receiver 2132 can be configured to receive information from the network device 220 through the antenna 2133, and the transmitter 2131 can be configured to send information to the network device 220 through the antenna 2133. The transmitter 2231 can be configured to send information to the terminal device 210 through the antenna 2233, and the receiver 2232 can be configured to receive information from the terminal device 210 through the antenna 2233.

[0210] The network device in the embodiments of the present application can include a chip in the network device. For example, the network device can include the processor 221, the memory 222, and the transceiver 223. The terminal device in the embodiments of the present application can include a chip in the terminal device. For example, the terminal device can include the processor 211, the memory 212, and the transceiver 213.

[0211] Figure 3 is a schematic block diagram of another communication system. Figure 3 An O-RAN system is shown. The O-RAN system in the present application can include Figure 3 In addition to the components shown, other components can also be included, or only some of the components shown can be included. Figure 3 Some components in the O-RAN system.

[0212] Referring to Figure 3 The network device can communicate with a core network device through a backhaul link 310, and communicate with a terminal device through an air interface. Exemplarily, a BBU in the network device can communicate with a core network device through the backhaul link 310. An RU in the network device can communicate with at least one terminal device through an air interface. The BBU can communicate with at least one RU through a front-haul link 330. Wherein, the BBU and the RU can be co-located or not co-located. Exemplarily, the BBU can include at least one CU and at least one DU. The CU and the DU can communicate through at least one mid-haul link 320.

[0213] Figure 4 is a schematic diagram of network element function division and protocol layer structure of an O-RAN system. The O-RAN system in the embodiments of the present application can adopt Figure 4 Some or all of the ways shown can be adopted to divide the network element function and the protocol layer, or other ways can be adopted.

[0214] In some examples, the CU can be used to carry logical nodes of an RRC layer, a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, and other control functions of the access network device. Illustratively, the CU can be connected to network nodes such as a core network through some interfaces, for example, the interfaces can include an E2 interface and the like. Optionally, the CU has part of the functions of the core network.

[0215] Illustratively, the CU (e.g., a PDCP layer or a layer higher than PDCP) is connected to the DU (e.g., a radio link control (RLC) layer or a layer lower than RLC) through some interfaces, for example, the interfaces can be an F1 interface and the like. In some examples, the above-mentioned interface (e.g., the F1 interface) can provide CP and UP functions, for example, interface management, system information management, UE context management, RRC message transmission, and the like. The F1 interface can adopt an F1 application protocol (F1AP).

[0216] In some examples, the CU can be split into a CU-CP and a CU-UP.

[0217] The CU-CP can be used to carry logical nodes of an RRC layer and a PDCP control plane part (PDCP-C) layer, for implementing control plane functions of the CU. The CU-CP can interact with network elements in the core network for implementing control plane functions. Illustratively, the network element in the core network for implementing control plane functions can be an access and mobility function network element, for example, an access and mobility management function (AMF) in a 5G system. Illustratively, the AMF network element can be used to be responsible for mobility management in a mobile network, such as location updating of a terminal device, registration of the terminal device to a network, handover of the terminal device, and the like.

[0218] The CU-UP can be used to carry logical nodes of an SDAP layer and a PDCP user plane part (PDCP-U) layer, for implementing user plane functions of the CU. The CU-UP can interact with network elements in the core network for implementing user plane functions. For example, a user plane function (UPF) in a 5G system, which can be used to be responsible for forwarding and receiving data in a terminal device.

[0219] The configuration of the above CU or DU is merely an example, and the CU or DU can be configured to have functions as needed. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have partial processing functions of the protocol layer. For example, partial functions of the RLC layer and functions of the protocol layer above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of the protocol layer below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to a service type or other system requirements, for example, according to a delay requirement. For example, functions that require to meet a shorter delay requirement in processing time are arranged in the DU, and functions that do not require to meet the delay requirement are arranged in the CU.

[0220] In some examples, the DU can be used to carry logical nodes of the RLC layer, the medium access control (MAC) layer, the higher physical (Higher PHY) layer, and other functions. In some examples, the DU can control at least one RU. For example, the DU can be connected to the RU through some interfaces, which can be a front-haul interface. In some examples, the Higher PHY layer can include part of the PHY layer processing, such as forward error correction (FEC) encoding, decoding, scrambling, modulation, or demodulation, and other processing functions.

[0221] In some examples, the RU can be used to carry logical nodes of the lower physical (Lower PHY) layer and radio frequency (RF) chain processing. In some examples, the RU can be a TRP, an RRH, or other similar functional entity in the third generation partnership project (3 rd generation partnership project,3GPP) In some examples, the Low PHY layer includes part of the PHY processing, such as fast Fourier transform (FFT), inverse fast Fourier transformation (IFFT), digital beamforming or filtering, and other processing functions. The RU can communicate with one or more UEs through a wireless link.

[0222] The DU and the RU can or can not be co-located. For example, the DU and the RU can exchange control plane and user plane information via a lower-layer split control / user / synchronization-plane (LLS-C / U / S) interface over a fronthaul link. For example, the O-RAN CUS plane in the DU can communicate with the O-RAN CUS plane in the RU over the LLS-C / U / S interface. Illustratively, the LLS-C / U / S can include a LLS-control (C) interface and a LLS-user (U) interface that provide CP and UP, respectively. In some examples, the CP can refer to real-time control between the DU and the RU. Management information can be exchanged between the DU and the RU over a LLS-management (M) interface of the fronthaul link, and the M plane can refer to non-real-time management operations between the DU and the RU. For example, the O-RAN M plane in the DU can communicate with the O-RAN M plane in the RU over the LLS-M interface. For another example, the O-RAN M plane in the DU or the RU can communicate with a management system over the LLS-M interface.

[0223] The DU and the RU can cooperate with each other to jointly implement the functions of the PHY layer. For example, one DU can be connected to one or more RUs. The functions of the DU and the RU can be configured in multiple ways according to design. For example, the DU can be configured to implement baseband functions, and the RU can be configured to implement mid- radio frequency functions. For another example, the DU is configured to implement high-layer functions (e.g., high PHY) in the PHY layer, and the RU is configured to implement low-layer functions (e.g., low PHY) in the PHY layer or implement the low-layer functions and radio frequency functions (e.g., RF chains). The high-layer functions in the PHY layer can include a portion of the functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another portion of the functions of the PHY layer that are closer to the mid-radio frequency side.

[0224] The 5th generation (5G) mobile communication system can use high frequency communication, i.e., use ultra-high frequency band (such as 28 GHz) signals to transmit data. One major problem of high frequency communication is that the signal energy sharply decreases with the transmission distance, resulting in a short signal transmission distance. To overcome this problem, high frequency communication uses analog beam technology, which concentrates signal energy in a small angular range by weighting the antenna array, forming a signal similar to a light beam (called an analog beam, simply referred to as a beam), thereby increasing the transmission distance. Both network devices and terminal devices need to use beams for transmission. When performing uplink and downlink data transmission, specific beams need to be used.

[0225] Currently, a terminal device and a network device select a suitable beam through a beam management procedure and communicate through the selected beam. The beam management procedure can include beam coarse alignment based on SSB first and beam fine adjustment based on CSI-RS. The beam management procedure can be divided into three stages. Hereinafter, the network device is taken as an example of a base station, and the three stages are introduced respectively.

[0226] Stage one: beam coarse alignment between the base station and the terminal device. In stage one, the base station beam and the terminal beam can be understood as a wide beam.

[0227] In stage one, the base station can perform beam sweeping. For example, as shown in FIG. 1, the base station can send SSBs to the terminal device through beams in different directions at different times. At the same time, the terminal device sweeps the receiving beam, that is, the terminal device also receives SSBs from the network device through beams in different directions at different times. The terminal device determines the optimal beam for the base station to send signals and the optimal beam for the terminal device to receive signals according to the received signal strength. The beam for the base station to send signals is referred to as a base station beam, and the beam for the terminal device to receive signals is referred to as a terminal beam. Figure 5a

[0228] Optionally, as shown in FIG. 2, the base station first sends SSB resource configuration information and reporting resource configuration information to the terminal device. In some examples, the SSB resource configuration information and the reporting resource configuration information can be carried in RRC signaling. For example, the SSB resource can be configured by the CSI-ResourceConfig element in the RRC signaling. Each configuration can contain one CSI-SSB-ResourceSet, and each set can contain up to 64 SSB resources. For example, the reporting resource can be configured by the CSI-ReportConfig element in the RRC signaling. The configuration content can include the time-frequency domain resource of the reporting feedback, the content of the reporting, and the like. Figure 5b In the case where the base station has established an RRC connection with the terminal device, the base station can configure the SSB resource configuration information and the reporting resource configuration information through RRC signaling. In the case where the base station has not established an RRC connection with the terminal device, the base station can send SSBs to the terminal device through predefined SSB resources. The base station beam can include

[0229] The terminal beam can include For example, the i-th (i=0, 1, …, M-1) SSB base station uses the beam B m , and the terminal uses the beam U n , where nM+m=mod(i, MN). The "mod" can represent the modulus. ​​

[0230] For example, referring to Figure 5b , assume that the base station beams include beams B0 to B 15 , that is, M = 16; assume that the terminal beams include beams U0 to U3, that is, N = 4. The base station can transmit SSBs to the terminal device using beam B0 through a corresponding SSB resource, transmit SSBs to the terminal device using beam B1, and so on, transmit SSBs to the terminal device using beam B 15 . The terminal device measures the SSBs transmitted by the base station through beams B0 to B 15 , respectively, through beams U0 to U3, respectively, to obtain measurement results.

[0231] The terminal device can determine a base station beam with better or best signal quality through the measurement results. The terminal device feeds back the base station beam with better or best signal quality to the network device.

[0232] Exemplarily, according to before and after the RRC connection establishment of the base station and the terminal device, two cases can be divided.

[0233] Before the RRC connection establishment, the SSB can carry a master information block (MIB). The MIB can indicate a channel resource carrying a SIB1. The base station can indicate a mapping relationship between an SSB and a random access channel occasion (RO) through a SIB1 message. The terminal device can perform random access through a physical random access channel (PRACH) resource corresponding to the optimal base station beam, so that the base station can obtain the optimal base station beam information.

[0234] After the RRC connection establishment, the terminal device can feed back according to a reporting resource configured in RRC signaling.

[0235] Phase two: base station beam fine adjustment.

[0236] The base station can determine a plurality of candidate beams according to the base station beam with better or best signal quality (which can also be referred to as the optimal base station beam) determined in phase one. Each candidate beam can be a narrow beam. The base station can perform scanning through a CSI-RS, and the terminal device can perform receiving through the receiving beam selected in phase one (or referred to as the optimal terminal beam), so as to perform fine adjustment on the base station beam.

[0237] For example, assume that the optimal terminal beam selected by the terminal device in phase one is U1. The candidate beams determined by the base station can include wherein K can be less than M, It can be A subset of. For example, suppose K = 3.

[0238] For example, such as Figure 6a As shown, the aforementioned candidate beams may include beams S0 through S2. Assuming that beam B3 is determined in stage one, this beam may be a wide beam. The base station can determine beams S0 through S2 based on beam B3.

[0239] For example, such as Figure 6b As shown, the base station can send CSI-RS configuration information to the terminal device. This CSI-RS configuration information can be used to configure CSI-RS resources and feedback reporting resources. For example, CSI-RS resources can be configured using the CSI resource configuration (CSI-ResourceConfig) element in RRC signaling. Similarly, feedback reporting resources can be configured by the base station using the CSI report configuration (CSI-ReportConfig) element in RRC signaling.

[0240] The base station can transmit CSI-RS sequentially, where the j-th CSI-RS can use beam S. j Where j = 0, 1, ..., K-1. The terminal equipment uses beam U1 for reception.

[0241] For example, the base station uses beam S0 to send CSI-RS to the terminal device through the corresponding CSI-RS resources, uses beam S1 to send CSI-RS to the terminal device through the corresponding CSI-RS resources, and uses beam S2 to send CSI-RS to the terminal device through the corresponding CSI-RS resources. The terminal device receives the CSI-RS sent by the base station through different beams via beam U1 and obtains the measurement results. The terminal device can determine the candidate beam with better or better signal quality based on the measurement results. The terminal device feeds back the candidate beam with better or better signal quality to the network device. For example, suppose the candidate beam with better or better signal quality is beam S1. The base station can use beam S1 as the beam for communication with the terminal device.

[0242] Phase 3: Fine-tuning of terminal equipment beams.

[0243] The base station can use the optimal beam obtained in Phase 2 to transmit CSI-RS. The terminal equipment scans the beam to determine the optimal terminal beam and complete beam alignment. A brief example is given below.

[0244] For example, the base station uses beam S1 to send CSI-RS to the terminal device, and the terminal device determines the optimal terminal beam as beam U1 through Phase 1. Beam U1 is a wide beam. The terminal device determines multiple candidate beams through beam U1, such as... Figure 7As shown, the plurality of candidate beams includes beam P1 to beam P4. The terminal device receives CSI-RS transmitted by the base station through beam S1 through beam P1 to beam P4 to obtain measurement results. The terminal device can select one beam from beam P1 to beam P4 according to the measurement results, and take the beam as a beam for communication with the base station.

[0245] The terminal device can also determine more or fewer candidate beams as an example above. The process of stage three is similar to stage two, and other descriptions can be referred to the description of stage two.

[0246] The communication system in the embodiments of the present application can implement all the processes of stages one to three described above, or can only implement part of the processes. For example, only stages one and two are implemented, and the terminal device can determine the beam by itself without the need of the base station to transmit CSI-RS.

[0247] Exemplarily, the network device can configure the terminal device to report the measurement results in one of the following three ways. The three ways can include: periodic reporting, semi-persistent reporting, and aperiodic reporting. The semi-persistent reporting can also be referred to as semi-static reporting. The following will be introduced respectively.

[0248] Periodic reporting: the network device can send reference signal resource configuration information to the terminal device. The reference signal resource configuration information can include periodic reference signal resources. The network device can configure the terminal device to periodically measure reference signals. The terminal device can measure the reference signals based on the reference signal resource configuration information, and periodically report the measurement results. Optionally, the measurement results obtained by the terminal device for the periodic measurement reference signals can be carried on the PUCCH resource.

[0249] Semi-persistent reporting: the terminal device can be configured to periodically measure the reference signal, but the measurement result is reported in a semi-persistent manner. In one possible implementation, the network device sends reference signal resource configuration information to the terminal device. The reference signal resource configuration information includes periodic reference signal resources. The network device configures the terminal device to periodically measure the reference signal. When the terminal device receives the activation signaling (e.g., MAC CE or DCI) from the network device, the terminal device can continuously report the measurement result. The network device can also send a deactivation instruction to the terminal device, thereby deactivating the semi-persistent reporting process of the terminal device. In another possible implementation, both the measurement of the reference signal and the reporting of the measurement result are semi-persistent. When the terminal device receives the activation signaling from the network device, the terminal device continuously measures the reference signal and reports the measurement result. When the terminal device receives the deactivation instruction from the network device, the terminal device stops reporting the measurement result. In addition, the measurement result can be carried on a PUCCH resource or a PUSCH resource.

[0250] Aperiodic reporting: when the terminal device receives a trigger instruction from the network device, the terminal device measures the reference signal and reports the measurement result. After completing the reporting, the terminal device stops reporting the measurement result. Optionally, the reference signal can be a periodic reference signal, a semi-persistent reference signal, or an aperiodic reference signal. Optionally, the measurement result is carried on a PUSCH resource.

[0251] Therefore, for the measurement result, either periodic reporting or trigger instruction signaling is issued by the network device to trigger the terminal device to perform semi-persistent reporting or aperiodic reporting. Therefore, the reporting occasion is completely determined by the network device.

[0252] In R19, terminal device or event triggered reporting of measurement results is introduced. For example, the terminal device can inform the network device that measurement result reporting is needed. For another example, an event occurs to trigger the terminal device to report the measurement result.

[0253] When the terminal device performs CSI calculation, some processing units of the terminal device are occupied, which can be referred to as CPU. At present, the CPU occupation time is determined according to the reporting time. In the CSI reporting initiated by the terminal device or the event triggered CSI reporting, the network device does not know when the terminal device triggers the CSI reporting, or does not know when the event occurs, so it cannot reasonably determine the CPU occupation time.

[0254] Therefore, how to reasonably determine the CPU occupation time is a problem to be solved.

[0255] Figure 8FIG. 8 is a schematic flowchart of a method 800 for determining the occupation time of a CPU, according to an embodiment of the present application. The optional operations in the method 800 are indicated by dashed lines. The method 800 considers the measurement resource and / or the first period when determining the occupation time of the CPU, so that the occupation time of the CPU is determined reasonably. The method 800 is described below in combination with Figure 8 FIG. 1. Figure 8

[0256] At S810, the first device receives configuration information from the second device. Correspondingly, the second device can send the configuration information to the first device.

[0257] The configuration information can be used to determine the measurement resource corresponding to the CSI report. For example, the configuration information can be information for configuring the measurement resource. For another example, the configuration information can be information for configuring other measurement resources. Alternatively, the first device determines the measurement resource according to the configuration information.

[0258] The present application does not limit the specific name of the configuration information. For example, the configuration information can also be referred to as CSI reporting configuration information, CSI reporting configuration (CSI-reportConfig), reporting configuration information, event-triggered reporting configuration information, or other names.

[0259] The CSI report can include one or more CSI reports. For example, the CSI report can include one or more measurement results corresponding to the measurement resource. For example, the measurement result can be a measurement result of a reference signal on the measurement resource.

[0260] In the embodiments of the present application, the CSI can be understood as a general CSI. For example, the CSI can include one or more parameters of the reference signal receiving power (RSRP) of a reference signal, the signal to interference plus noise ratio (SINR) of a reference signal, or the reference signal index. The CSI can also include other parameters.

[0261] The present application does not limit the specific name of the CSI report. For example, the CSI report can also be referred to as event-triggered beam reporting, beam measurement result reporting, interference measurement reporting, event-related reporting or reporting, event-triggered or UE-initiated reporting or reporting, event-triggered or UE-initiated beam reporting or reporting, event-triggered or UE-initiated CSI report, event-triggered or UE-initiated beam measurement result report, event-triggered or UE-initiated interference measurement report, interference measurement report, CSI report, beam measurement result report, or other names. ​

[0262] The measurement resource can be used for measurement of the CSI report. For example, the first device can determine, according to the measurement resource, a measurement resource for measuring the reference signal, measure the reference signal in the corresponding measurement resource to obtain a measurement result of the reference signal, and obtain the CSI report. Optionally, the method 800 further includes: the first device sending the CSI report to the second device.

[0263] The measurement resource can be a periodic resource. For example, the measurement resource can include a plurality of measurement resource periods, and each measurement resource period corresponds to a part of the measurement resource. The measurement resource can also be a non-periodic resource. Optionally, the measurement resource is not later than the measurement resource corresponding to the CSI reference resource.

[0264] For example, the measurement resource can include a CSI-RS resource, an SSB resource, and the like. In the embodiments of the present application, the beam, the TCI state, the CSI-RS resource, the SSB resource, the SRS resource, and the reference signal can be replaced with each other.

[0265] The specific name of the measurement resource is not limited in the present application. For example, the measurement resource can also be referred to as a serving beam measurement resource, a reference signal resource corresponding to a serving beam, a new beam measurement resource, a reference signal resource corresponding to a new beam, a reference signal resource, a beam, a serving beam, a reference signal, or other names.

[0266] S860, the first device determines the occupation time of the CPU according to the measurement resource and / or the first period.

[0267] The occupation time of the CPU can correspond to the CSI report. For example, the occupation time of the CPU can be the time during which the first device processes the CSI report and occupies the CPU. The CPU can include one or more CPUs. In some examples, the actual number of CPUs can be related to the reporting amount of the CSI report.

[0268] In the embodiments of the present application, the first period can be understood in two ways. For ease of description, they are denoted as understanding 1 and understanding 2.

[0269] Understanding 1: the first period is a measurement resource period of the measurement resource.

[0270] In understanding 1, the measurement resource can be periodically distributed. For example, the measurement resource can include a plurality of measurement resource periods, and the first period can be one of the plurality of measurement resource periods of the measurement resource. For another example, the second device (e.g., a network device) can configure a measurement resource period of the measurement resource, and the first device (e.g., a terminal device) can receive a reference signal carried by the measurement resource in the measurement resource period. In this way, the first period can be for each measurement resource period (or, any one measurement resource period) of the measurement resource. For example, the second device (e.g., a network device) can configure a measurement resource period of the measurement resource as 4 slots, 8 slots, or the like.

[0271] Understanding 2: The first period is a period of the first resource. Wherein, the first resource can be used to send information related to the CSI report.

[0272] For example, the first resource can include a plurality of transmission occasions (or, resource periods, periods, transmission periods, or occasions), wherein the plurality of transmission occasions can include a first transmission occasion and a second transmission occasion. The first transmission occasion and the second transmission occasion can be two adjacent transmission occasions in the plurality of transmission occasions. The term "adjacent" can be understood as that between the first transmission occasion and the second transmission occasion, there is no other transmission occasion in the plurality of transmission occasions. The term "adjacent" does not mean that the first transmission occasion and the second transmission occasion are continuous in the time domain. There can also be other time domain units between the first transmission occasion and the second transmission occasion. In other words, the first transmission occasion and the second transmission occasion can have a certain interval in the time domain.

[0273] In the embodiments of the present application, the resource period, the transmission occasion, the period, the transmission period, and the occasion can be replaced with each other.

[0274] The first period can include a time interval between the first transmission occasion and the second transmission occasion. Wherein, the time interval can be represented by one or more time domain units. For example, there are 10 time domain units between the first transmission occasion and the second transmission occasion, and the first period can include the above 10 time domain units. Exemplarily, the time domain unit can include any one or more of a slot, a symbol, or an orthogonal frequency division multiplexing (OFDM) symbol, a subframe, a frame, a millisecond (ms), a second (s). The time domain unit can also include other meanings.

[0275] It can also be understood that the first resource is a periodic resource, and the first period is a period of the first resource. For example, the second device (e.g., a network device) can configure the period of the first resource of the first device (e.g., a terminal device). For example, the second device (e.g., a network device) can configure the period of the first resource as 8 slots.

[0276] Optionally, the first period can include a time domain unit occupied by the first transmission occasion and / or the second transmission occasion. For example, the first period can include a time domain unit occupied by the first transmission occasion, and a time interval between the first transmission occasion and the second transmission occasion. For another example, the first period can include a time domain unit occupied by the second transmission occasion, and a time interval between the first transmission occasion and the second transmission occasion. For another example, the first period can include time domain units occupied by the first transmission occasion and the second transmission occasion, and a time interval between the first transmission occasion and the second transmission occasion.

[0277] Optionally, the first period can include time domain units from the first transmission occasion to the second transmission occasion. For example, the first period can include a first time domain unit from the first transmission occasion, and a time domain unit closest to the second transmission occasion before the second transmission occasion. For another example, the first period can include a first time domain unit after the first transmission occasion, and a last time domain unit of the second transmission occasion. For another example, the first period can include a first time domain unit from the first transmission occasion, and a last time domain unit of the second transmission occasion. For another example, the first period can include a first time domain unit after the first transmission occasion, and a time domain unit closest to the second transmission occasion before the second transmission occasion. The first transmission occasion or the second transmission occasion can occupy one or more time domain units. The first transmission occasion can be before the second transmission occasion, or after the second transmission occasion. For example, the first transmission occasion can be before or after the second transmission occasion in time domain. The following is described taking the first transmission occasion before the second transmission occasion as an example.

[0278] In understanding 2, the measurement resource can be in the first period in time domain. For example, the second device (e.g., a network device) can configure the measurement resource A for the first device (e.g., a terminal device). Wherein the first period is one of the plurality of periods of the first resource, the measurement resource is the measurement resource A in the first period, or the measurement resource is the measurement resource A in the first period and no later than the corresponding CSI reference resource.

[0279] Optionally, the corresponding CSI reference resource can be understood as a time occasion corresponding to a Mth time length before a downlink time occasion corresponding to the second transmission occasion of the first resource. For example, if the uplink time slot corresponding to the second transmission occasion of the first resource is n', the downlink time occasion corresponding to the second transmission occasion of the first resource can be understood as time slot n-M. Wherein, the Mth time length can be determined by one or more of network configuration, terminal capability reporting, protocol specification, etc. wherein μ DL and μ UL are respectively the downlink and uplink subcarrier spacing configurations. For another example, if the Mth time length is M time slots, the corresponding CSI reference resource can be downlink time slot n-M. Wherein, the Mth time length can be determined by one or more of network configuration, terminal capability reporting, protocol specification, etc.

[0280] Based on the above scheme, in the process of determining the occupation time of the CPU corresponding to the CSI report, the first device can consider the measurement resource, the measurement resource period, or the period of the first resource related to the CSI report, thereby reasonably determining the occupation time of the CPU. Therefore, the above scheme can make the network device reasonably configure the measurement of the reference signal measurement resource and the reporting of the CSI, so that the first device efficiently utilizes the CPU and reduces the conflict of CSI reporting.

[0281] In some possible implementation manners, the configuration information is used to indicate that the CSI report exists a reporting quantity, and / or the sending of the CSI report is event triggered or initiated by the first device. Optionally, the CSI report includes the reporting of event information. The description of "event" or "event information" can be referred to later.

[0282] The configuration information can indicate that the CSI report exists a reporting quantity. For example, the configuration information includes a "report quantity" field, and the field is not "none".

[0283] In some possible implementation scenarios, the configuration information does not configure a reporting resource, wherein the reporting resource can be used to send the CSI report (for example, the CSI report). Therefore, even if there is a reporting quantity, since the second device is not configured with a reporting resource, the second device does not know the reporting time of the first device, so as to determine the occupation time of the CPU according to the reporting time / reporting resource.

[0284] In some possible implementation manners, the CSI report existing a reporting quantity can not be indicated by the configuration information. For example, other information can indicate that the CSI report exists a reporting quantity. For another example, the CSI report existing a reporting quantity is pre-configured or pre-defined.

[0285] The sending of the CSI report can be event triggered or initiated by the first device. For example, the configuration information indicates that the CSI report is event triggered reporting or the CSI report is associated with an event triggered reporting configuration. The event triggered reporting configuration is described below and will not be described here. The sending of the CSI report can be event triggered, which can be understood as sending the CSI report when an event condition is met, or sending the CSI report when a measurement result of a reference signal carried by a measurement resource associated with the CSI report meets an event condition. Alternatively, the method 800 further includes: S805, the first device sends capability information to the second device, the capability information indicating a capability supported by the first device. For example, the capability information indicates whether the first device supports the capability of event triggered reporting. When the capability information indicates that the first device supports the capability of event triggered reporting, the second device can configure event triggered reporting for the first device.

[0286] To configure event triggered reporting can include two aspects. One aspect is event related configuration for configuring events, and the other aspect is reporting related configuration for configuring reporting conditions, reporting contents, or reporting manners of the first device.

[0287] The event and the event related configuration are described below. The event can be configured by the second device (for example, a network device), can be defined by a protocol, or can be reported by the capability of the first device (for example, a terminal).

[0288] Taking the first device as a UE as an example, the event can represent an event related to UE initiated reporting (UE initiated report), an event related to UE initiated measurement report reporting, an event related to UE active measurement report (or measurement report), or a specific condition related to UE initiated reporting (or measurement report reporting). For example, the terminal device can actively perform measurement (such as beam measurement or channel measurement), and then obtain measurement results related to the event. When the measurement results meet the event condition, the terminal device reports the measurement results related to the event. For another example, the terminal device can perform measurement based on a reference signal according to a reference signal resource configuration, and then obtain measurement results related to the event. When the measurement results meet the event condition, the terminal device reports the measurement results related to the event. For another example, the terminal device actively performs measurement and reports the measurement results related to the event when a specific condition is met. The CSI report includes the measurement results related to the event.

[0289] The present application does not limit the specific name of the event, for example, the event can also be referred to as a trigger event, a layer 1 (L1) trigger event, a CSI measurement reporting trigger event, a beam measurement reporting trigger event, an L1 CSI reporting trigger event, an L1 beam measurement reporting trigger event, or other names.

[0290] Exemplarily, the event can include one or more of the following:

[0291] The signal quality of the current serving beam is less than a first threshold;

[0292] The signal quality of the current serving beam is less than or equal to a first threshold;

[0293] The signal quality of at least one new beam is greater than a second threshold;

[0294] The signal quality of at least one new beam is greater than or equal to a second threshold;

[0295] The difference between the signal quality of at least one new beam and the signal quality of the current serving beam is greater than a third threshold;

[0296] The difference between the signal quality of at least one new beam and the signal quality of the current serving beam is greater than or equal to a third threshold;

[0297] The signal quality of the current serving beam is less than a fourth threshold, and the signal quality of at least one new beam is greater than a fifth threshold;

[0298] The signal quality of the current serving beam is less than or equal to a fourth threshold, and the signal quality of at least one new beam is greater than a fifth threshold;

[0299] The signal quality of the current serving beam is less than a fourth threshold, and the signal quality of at least one new beam is greater than or equal to a fifth threshold;

[0300] The signal quality of the current serving beam is less than or equal to a fourth threshold, and the signal quality of at least one new beam is greater than or equal to a fifth threshold;

[0301] The absolute value of the difference between the signal quality of at least one new beam and the signal quality of the current serving beam is less than a sixth threshold;

[0302] The absolute value of the difference between the signal quality of at least one new beam and the signal quality of the current serving beam is less than or equal to a sixth threshold;

[0303] The signal quality of the current serving beam is less than a seventh threshold of the beam quality of a preset beam, wherein the current serving beam can be a CSI-RS whose QCL type is typeD in the currently indicated TCI-state, and the preset beam can be an SSB whose QCL type is typeD and which satisfies the CSI-RS;

[0304] a seventh threshold of the beam quality of the preset beam;

[0305] the current beam is not in the multiple beams of the best quality;

[0306] at least one new beam is higher than a eighth threshold of the worst RS (QCL type D) in the activated TCI states;

[0307] at least one new beam is higher than a eighth threshold of the best RS (QCL type D) in the activated TCI states;

[0308] the multiple new beams are higher than a ninth threshold of the quality of the current beam;

[0309] there is at least one new beam whose quality is higher than a tenth threshold of the configured reference signal.

[0310] The units corresponding to the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold, the seventh threshold, the eighth threshold, the ninth threshold and the tenth threshold respectively can be dBm (decibel milliwatt) or dB (decibel).

[0311] Exemplarily, the first threshold is -100 dBm, the second threshold is -90 dBm, the third threshold is 10 dB, the fourth threshold is -100 dBm, the fifth threshold is -90 dBm, and the sixth threshold is 4 dB.

[0312] The current serving beam can be one or more of the following:

[0313] The reference signal of the current indicated TCI state is of QCL type D;

[0314] The reference signal of the current indicated TCI state is of QCL type D, and the SSB corresponding to the reference signal satisfies the QCL type D relationship;

[0315] The reference signal of the current indicated TCI state is of QCL type D, and the SSB corresponding to the reference signal satisfies the QCL type D relationship;

[0316] The reference signal of the current indicated TCI state is of QCL type D, and the SSB corresponding to the reference signal satisfies the QCL type D relationship;

[0317] one or more reference signals configured or indicated by the network device for monitoring the current beam;

[0318] activating the RS with the worst quality (QCL type D) in the TCI states;

[0319] activating the RS with the best quality (QCL type D) in the TCI states.

[0320] The aforementioned reference signals can be SSB / CSI-RS / SRS / TRS / path loss (PL) RS. The current beam can be one or more beams or reference signals. Wherein, the beam can also be referred to as the beam corresponding to the reference signal. The above-mentioned beam (or reference signal) can be a beam of a serving cell, or a beam of a candidate cell / neighbor cell.

[0321] Wherein, the "quality" can include at least one of the following: RSRP, SINR, layer 1-RSRP (L1-RSRP), layer 1-SINR (L1-SINR), synchronization signal based RSRP (SS-RSRP), synchronization signal based SINR (SS-SINR), CSI reference signal based RSRP (CSI-RSRP), or CSI reference signal based SINR (CSI-SINR).

[0322] Exemplarily, the configuration information can be used to configure the above-mentioned events. However, the present application does not limit this, and the above-mentioned events can also be configured by other information. Wherein, the information used to configure the above-mentioned events can be referred to as event information. For example, the configuration information can include event information. Wherein, the event information can include one or more event indexes, or an event table. The event table can contain one or more events.

[0323] In some possible implementations, in the case where the events are configured, the events can not be activated temporarily. For example, even if the events have been configured, and the events have reached the triggering condition (for example, the signal quality of the current serving beam is less than the first threshold), however, since the events are not activated, the events will not be triggered. The second device can send activation signaling to the first device for activating part or all of the configured events; or send deactivation signaling for deactivating part or all of the configured events.

[0324] The following introduces the related configuration of the reporting.

[0325] The configuration information of the event triggered reporting (or referred to as measurement report configuration) can be carried in the configuration information. In other words, the configuration information can be used to determine the related configuration of the event triggered reporting. However, the present application does not limit this, and the configuration of the event triggered reporting can also be determined by other information, or be predefined or preconfigured.

[0326] Exemplarily, the configuration of the event triggered reporting can be CSI-reportConfig, which can configure an indication information. For example, the reporting configuration type (reportConfigType) can be configured as EventTriggered, which is used to indicate that the reporting configuration is the configuration of the event triggered reporting. For another example, the CSI-reportConfig can contain event related information, such as event index, threshold corresponding to the event and the like, which indicates that the reporting configuration is the configuration of the event triggered reporting. For another example, the configuration of the event triggered reporting is configured through a special information element, for example, L1-EventTriggered-CSI-ReportConfig (L1 event triggered CSI reporting configuration). The CSI reporting corresponds to the configuration of the event triggered reporting.

[0327] The configuration of the event triggered reporting can contain one or more of the following information or be associated with at least one of the following information:

[0328] Cell information. The cell information can be used to indicate the cell to which the measurement resource related to the event belongs. For example, the cell information can include the serving cell index or identifier.

[0329] Information of one or more supported events. The information of the event can indicate the event, for example, the index of the event and the like. The event can refer to the description above.

[0330] Measurement resource (or referred to as reference signal resource, or referred to as reference signal measurement resource) corresponding to one or more events. The measurement resource can be configured separately for each event, that is, different events correspond to different measurement resources. Multiple events can also be configured with the same measurement resource. The measurement resource corresponding to one or more events can include the measurement resource described above. The specific description can refer to the foregoing.

[0331] Event triggered reporting resource, which is used to carry the reporting of event triggered beam measurement results, such as periodic PUCCH resource, aperiodic PUSCH resource, semi-persistent PUCCH resource, or semi-persistent PUSCH resource, etc. Only one reporting resource can be configured, i.e., the same reporting resource corresponds to each cell, or a reporting resource can be configured for each cell. Among them, the event triggered reporting resource can be replaced by PUCCH resource, PUSCH resource, channel resource, reporting resource, or UE triggered reporting resource.

[0332] Scheduling request or indication resource, which is used to carry the indication information of event occurrence, the indication information is used to indicate to the network device that the event triggered beam measurement result needs to be reported and / or there is event occurrence, or is used to request the event triggered reporting resource. Only one reporting indication resource can be configured, i.e., the same scheduling request or indication resource corresponds to each cell, or a scheduling request or indication resource can be configured for each cell. Among them, the scheduling request or indication resource can be replaced by reporting indication resource, PUCCH indication resource, PUSCH indication resource, channel resource, scheduling request resource, pre-indication resource, pre-notification resource, event triggered reporting scheduling request resource, or UE triggered reporting scheduling request resource.

[0333] One or more reporting quantities (or measurement result information, reporting content, or reporting parameters, etc.) when one or more events occur. The reporting quantity corresponding to each event can be network configured or protocol specified. The reporting quantity can be one or more of event index, cell index, current beam reference signal index, new beam reference signal index, reference signal index, L1-RSRP, L1-SINR, or other content. Optionally, the reporting quantity also includes the reporting number corresponding to the reporting quantity, etc. For example, the reporting number corresponding to the reference signal, the reporting number of the new beam. More examples of reporting quantity are described below, and are not described here.

[0334] Event triggered reporting mode, such as Mode A or Mode B. In this application, Mode A and Mode B are just a way of saying, and can be other ways of saying. The description of Mode A and Mode B is described below.

[0335] The following examples are used to introduce examples of reporting quantities. Exemplarily, the reporting quantity can include one or more of the following reporting parameters:

[0336] Reporting parameter #1, current serving beam index, which can be understood as the index of the reference signal of QCL type typeD in the currently indicated TCI-state; or the index of the reference signal of type QCL type D in the currently indicated TCI state that satisfies the QCL type D relationship; or the index of the reference signal of QCL type typeD in the UL TCI-state currently applied to the current uplink transmission (PUSCH / PUCCH / SRS / PRACH); or the index of the reference signal of QCL type typeD in the DL or joint TCI-state currently applied to the current downlink transmission (PDCCH / PDSCH / CSI-RS). Exemplarily, the above-mentioned current uplink transmission can include PUSCH transmission, PUCCH transmission, SRS transmission, or PRACH transmission. Exemplarily, the above-mentioned downlink transmission can include PDCCH transmission, PDSCH transmission, or CSI-RS transmission.

[0337] Reporting parameter #2, quality of the current serving beam. For example, RSRP, SINR, L1-RSRP, L1-SINR, SS-RSRP, CSI-RSRP, SS-SINR, or CSI-SINR of the current serving beam. Wherein the current serving beam can include one beam or multiple beams, which is not limited in the present application. The number of the current serving beam can be determined according to the number of UL / DL / joint TCI states indicated by the network device, such as the UL / DL / joint TCI state indicated by the DCI signaling. Alternatively, the number of beams included in the current serving beam can be protocol predefined or preconfigured. Alternatively, the maximum number of beams included in the current serving beam can be protocol predefined or configured by the network device.

[0338] Reporting parameter #3, index of the new beam, which can be understood as the index of the reference signal of QCL type typeD in the activated TCI-state (except the indicated TCI-state), or the index of one or more reference signals (except the reference signal corresponding to the current serving beam) in the reference signal configured by the network device (such as the reference signal configured by the network device for measurement, or such as the reference signal configured by the network device for the terminal device to monitor the occurrence of the event).

[0339] Reporting parameter #4, quality of new beam. For example, the quality of new beam can be RSRP, SINR, L1-RSRP, L1-SINR, SS-RSRP, CSI-RSRP, SS-SINR, or CSI-SINR of at least one new beam. Wherein, the new beam can include one beam or multiple beams, which is not limited in the present application. The number of beams included in the new beam can be protocol predefined or preconfigured. Alternatively, the maximum number of beams included in the new beam can be protocol predefined or configured by the network device.

[0340] Reporting parameter #5, cell information, which can be understood as which cell the reported measurement report corresponds to, or which cell's reference signal resource is measured. For example, the cell information can be handover candidate cell ID, additional PCI, component carrier (CC) index, PCI, or serving cell index, etc.

[0341] Reporting parameter #6, reason why the quality of the current serving beam is lower than the threshold (e.g., the first threshold). For example, the network device beam misalignment, the terminal device receiving beam misalignment, the transmitting and receiving beam misalignment, etc. The misalignment can also be replaced by the words such as expiration, invalidation, etc. Alternatively, it indicates whether the CSI-RS set measurement triggered by "repetition" is "on", which is used to poll the receiving beam on the terminal device side.

[0342] Reporting parameter #7, reference signal resource set index. For example, CSI-RS resource set (CSI-RS-ResourceSet) index, CSI interference measurement (IM) resource set (CSI-IM-ResourceSet) index, CSI-SSB resource set (CSI-SSB-ResourceSet) index, or the reference signal resource set index configured by the network device for the terminal device to monitor the occurrence of the event, which is used to indicate which reference signal resource set the reported current serving beam and / or second beam belongs to.

[0343] Reporting parameter #8, reporting configuration index, for example, CSI report configuration identification (CSI-ReportConfigId), or event triggered reporting configuration index.

[0344] Reporting parameter #9, event information. For example, the index of the event that occurs, or one or more bits used to indicate whether the event occurs. For example, the event information includes M bits, An index used to indicate an event that has occurred. For example, event information includes X bits, each corresponding to one of X events. The x-th bit of the X bits indicates whether the event corresponding to that x-th bit has occurred, where x = 1, 2, ..., X. For instance, if the x-th bit has a value of "0", then the x-th bit indicates that the event corresponding to that x-th bit has occurred; or, if the x-th bit has a value of "1", then the x-th bit indicates that the event corresponding to that x-th bit has occurred.

[0345] Report parameter #10, the capability index, can be used to determine the maximum number of SRS ports.

[0346] Report parameter #11, channel state information, which may include one or more of the following: precoding matrix indication (PMI), rank indication (RI), channel quality information (CQI), and layer indication (LI).

[0347] Based on the above scheme, when an event is triggered to report, the first device initiates a report, or there is a reporting volume, the first device can reasonably determine the CPU usage time based on the measurement resources related to the CSI report, the measurement resource cycle of the measurement resources, or the cycle of the first resource.

[0348] Figure 9 This is a schematic diagram illustrating two types of event-triggered reporting provided in the embodiments of this application.

[0349] Below, in conjunction with Figure 9 In section (a), an exemplary method 900 of Mode A is described.

[0350] Mode A can also be called event-triggered reporting based on Mode A, or event-triggered reporting based on the first mode. The naming of this application embodiment is not limited.

[0351] S910, the first device may send first information at a transmission timing in the first indicated resource, the first information being used to request the scheduling of resources for the CSI report. Correspondingly, the second device receives the first information from the first device.

[0352] Optionally, the first device sends the first information when an event occurs or when the event conditions are met.

[0353] For example, the first information may be PUCCH signaling. The first indication resource may be the aforementioned scheduling request or indication resource.

[0354] In some examples, the first device can transmit the first information at one of the transmission occasions in the first indication resource, the first information carrying or comprising request information for requesting resources for the CSI reporting.

[0355] Referring to (b) in Figure 9 , the first indication resource can comprise a plurality of transmission occasions. The plurality of transmission occasions can be periodically distributed in time domain. The first information can be transmitted at one of the transmission occasions in the first indication resource for requesting resources for the CSI reporting. After receiving the first information, the second device can transmit second information to the first device for indicating a second reporting resource for transmitting the CSI reporting. The first device can transmit the CSI reporting at the second reporting resource.

[0356] S920, the second device can transmit second information to the first device, the second information being for indicating a second reporting resource for transmitting the CSI reporting.

[0357] Exemplarily, the second information can be DCI. The second information can also be referred to as scheduling signaling or other names. In some examples, the second information can be uplink scheduling DCI for scheduling PUSCH. For example, the uplink scheduling DCI is for indicating an index of a PUSCH. In other examples, the second information can be downlink scheduling DCI for scheduling PUCCH. For example, the downlink scheduling DCI is for indicating an index of a PUCCH.

[0358] S930, the first device transmits the CSI reporting at the second reporting resource.

[0359] The CSI reporting can be referred to as event-related measurement reporting.

[0360] The CSI reporting can be carried in uplink signaling. For example, the CSI reporting can be carried in PUSCH or PUCCH. The first device determines the transmission resource (i.e., the second reporting resource) of the CSI reporting according to the second information of S920, and transmits the CSI reporting.

[0361] In (b) in Figure 9 , the second reporting resource is located after the first transmission occasion (denoted as transmission occasion 2) after the transmission occasion (denoted as transmission occasion 1) corresponding to the first information. However, embodiments of the present application do not limit the specific location of the second reporting resource. For example, the second reporting resource can be located between the transmission occasion 1 and the transmission occasion 2. For another example, the second reporting resource can be located after the transmission occasion 2.

[0362] Next, an exemplary method 950 of Mode B is introduced in connection with (c) in Figure 9 .

[0363] Mode B can also be referred to as event triggered reporting based on Mode B, or event triggered reporting based on the second mode, and the naming thereof is not limited by the embodiments of the present application. S960, the first device can send the first information at the third sending occasion. Correspondingly, the second device receives the first information from the first device. Optionally, the first information indicates that there is a CSI report associated with the fourth sending occasion of the third sending occasion. Optionally, the first information indicates whether there is a CSI report associated with the fourth sending occasion of the third sending occasion. Optionally, the first information indicates that there is an event occurrence. Optionally, the first information indicates whether there is an event occurrence.

[0364] The above S960 can be understood as: the first device informs the second device through the first information that the first device will send the CSI report (or beam information) through the fourth sending occasion (or uplink signaling carrying the CSI report), or that the first device informs the second device through the first information that there is an event occurrence, and the first device will send the CSI report (or beam information) through the fourth sending occasion (or uplink signaling carrying the CSI report).

[0365] Exemplarily, the first information can be PUCCH signaling or sent through PUCCH signaling. The first indication resource can be the aforementioned scheduling request or indication resource. The first information can also be MAC CE signaling or sent through MAC CE signaling.

[0366] Among them, the third sending occasion can be the sending occasion of the first information in the first indication resource. For example, see (d) in Figure 9 It can be understood that the first indication resource can include multiple sending occasions, and the multiple sending occasions can be periodically distributed in the time domain. These sending occasions can be used to send the first information, but the third sending occasion represents the sending occasion of actually sending the first information. For ease of description, the sending occasions in the first indication resource other than the third sending occasion can be referred to as "remaining sending occasions". The first device has the ability or opportunity to send the first information at the remaining sending occasions, but the first device does not send the first information at the remaining sending occasions.

[0367] Among them, the fourth sending occasion can be a sending occasion in the first reporting resource.

[0368] See Figure 9(d) of the first reporting resource can comprise a plurality of transmission occasions, the plurality of transmission occasions can be periodically distributed in time domain, and the transmission occasions can be used for transmitting the CSI report. Exemplarily, the first reporting resource can be a pre-configured PUCCH or PUSCH resource. For example, the first reporting resource can be a pre-configured grant-free PUSCH (CG-PUSCH). The first reporting resource can be the aforementioned event-triggered reporting resource.

[0369] The fourth transmission occasion can be one or more transmission occasions in the first reporting resource associated with the third transmission occasion. The fourth transmission occasion can also be associated with other transmission occasions in the first indication resource except the third transmission occasion, and can also be associated with transmission occasions in other indication resources except the first indication resource.

[0370] The “fourth transmission occasion is associated with the third transmission occasion” can be understood as: if the first information is received at the third transmission occasion, the second device can determine that the content indicated by the first information acts on the fourth transmission occasion. For example, the second device receives the information of “there is a CSI report” or “there is an event occurrence” at the third transmission occasion, and the second device can determine that there is a CSI report at the fourth transmission occasion. The “fourth transmission occasion is associated with the third transmission occasion” can also be understood in other ways. For example, the fourth transmission occasion and the third transmission occasion have an association relationship, a corresponding relationship, a mapping relationship or other relationships. Figure 9 (d) of the first reporting resource can comprise a plurality of transmission occasions, the plurality of transmission occasions can be periodically distributed in time domain, and the transmission occasions can be used for transmitting the CSI report. Exemplarily, the first reporting resource can be a pre-configured PUCCH or PUSCH resource. For example, the first reporting resource can be a pre-configured grant-free PUSCH (CG-PUSCH). The first reporting resource can be the aforementioned event-triggered reporting resource.

[0371] However, there can be other association modes between the first indication resource and the first reporting resource, which are not limited in the present application. For example, part of the transmission occasions in the first indication resource are one-to-one associated with part of the transmission occasions in the first reporting resource. For another example, one transmission occasion in the first indication resource is associated with one or more transmission occasions in the first reporting resource. For another example, one or more transmission occasions in the first indication resource are associated with one transmission occasion in the first reporting resource.

[0372] For ease of description, the transmission occasion in the first reporting resource associated with the remaining transmission occasions can be referred to as an associated transmission occasion. In some possible implementations, the first device can transmit the first information on the third transmission occasion, and can also transmit the indication information on the remaining transmission occasions. For ease of distinction, the indication information transmitted on the remaining transmission occasions is referred to as first information'. In another possible implementation, the first device can transmit the first information on the third transmission occasion, and does not transmit information on the remaining transmission occasions.

[0373] Optionally, the first information indicates that the fourth transmission occasion associated with the third transmission occasion has the CSI report. In this way, the second device can determine, from the first information received on the third transmission occasion, that the fourth transmission occasion associated with the third transmission occasion has the CSI report.

[0374] Optionally, the first device transmits the first information described above in a case where an event occurs or an event condition is met.

[0375] For example, the first device can not transmit the first information' on the remaining transmission occasions, and can transmit the first information on the third transmission occasion. In this way, the second device can determine that the associated transmission occasion corresponding to the transmission occasion (i.e., the remaining transmission occasion) on which the first information' is not received does not have the CSI report, and that the fourth transmission occasion corresponding to the transmission occasion (i.e., the third transmission occasion) on which the first information is received has the CSI report.

[0376] For another example, the above case can be described as follows: the first device can not transmit the first information on the remaining transmission occasions, and can transmit the first information on the third transmission occasion. In this way, the second device can determine that the associated transmission occasion corresponding to the transmission occasion (i.e., the remaining transmission occasion) on which the first information is not received does not have the CSI report, and that the fourth transmission occasion corresponding to the transmission occasion (i.e., the third transmission occasion) on which the first information is received has the CSI report.

[0377] Optionally, the first information indicates whether the fourth transmission occasion associated with the third transmission occasion has the CSI report. In this way, the second device can determine, from the first information received on the third transmission occasion, whether the fourth transmission occasion has the CSI report according to the content indicated by the first information. For example, the first information is used to indicate that the fourth transmission occasion associated with the third transmission occasion has the CSI report, and the first information' is used to indicate that the associated transmission occasion corresponding to the remaining transmission occasion does not have the CSI report.

[0378] Optionally, the first device sends the first information to indicate that the fourth sending occasion exists the CSI report in the case that the event occurs or the event condition is met. Optionally, the first device sends the first information to indicate that the fourth sending occasion does not exist the CSI report in the case that no event occurs, no event condition is met, or the event condition is not met.

[0379] S970, the first device sends the CSI report at the fourth sending occasion.

[0380] Examples of the CSI report can refer to the description of S930, and will not be repeated.

[0381] Figure 10 are some schematic diagrams of the occupation time of the CPU provided by the embodiments of the present application. The following describes some examples of the occupation time of the CPU determined by S860. Figure 10 are some schematic diagrams of the occupation time of the CPU provided by the embodiments of the present application. The following describes some examples of the occupation time of the CPU determined by S860.

[0382] In the related description of Figure 10 , the measurement resource can be a periodic resource or a semi-persistent resource associated with event-triggered reporting. The measurement resource can be understood as a resource for a reference signal associated with event-triggered reporting. The measurement resource can be associated with a configuration of event-triggered reporting, and the configuration of event-triggered reporting is associated with a CSI report. Specifically, the measurement resource can be a periodic resource, for example, a periodic SSB resource or a periodic CSI-RS resource. For another example, the measurement resource can be a resource in a semi-persistent resource except for a periodicity triggered by DCI (i.e., the first periodicity triggered in the semi-persistent resource). Exemplarily, the measurement resource in the first periodicity can include a CSI-RS resource and / or an SSB resource.

[0383] The following first describes the meaning of the first periodicity as an example of understanding 1, denoted as example 1-1.

[0384] Example 1-1: The present application provides a method for determining the occupation time of a CPU. The method comprises: a first device receiving configuration information, the configuration information being used to determine a measurement resource corresponding to a CSI report (or referred to as CSI reporting); the first device determining the occupation time of the CPU according to the measurement resource and a first periodicity, the occupation time of the CPU being a time during which the first device processes the CSI report and occupies the CPU; wherein the first periodicity is a measurement resource periodicity of the measurement resource.

[0385] Wherein, refer to (a) in Figure 10 , the start point of the occupation time of the CPU is the first time domain unit (for example, a symbol or an OFDM symbol) of the measurement resource in the first periodicity, and the end point of the occupation time of the CPU is the last time domain unit of the measurement resource in the first periodicity plus a first time length.

[0386] Refer toFigure 10 In (a) of FIG. 8, the measurement resource can include multiple measurement resource periods, for example, Figure 10 In (a) of FIG. 8, four measurement resource periods of the measurement resource are shown. In other words, Figure 10 In (a) of FIG. 8, four first periods are shown, i.e., the length of the first period is equal to the length of the measurement resource period. However, the present application is not limited thereto, and the measurement resource can have more or fewer periods.

[0387] Figure 10 The first period shown in (a) of FIG. 8 is only an example. Those skilled in the art can understand that the start and end of the first period can also have other possibilities, which are not limited by the present application.

[0388] The first duration can be one or more time domain units, and the first duration can also be 0. For example, the first duration can be Z3’ symbols. The first duration can be configured by a second device (e.g., a network device), reported by a first device (e.g., a terminal device), or pre-configured or pre-defined. The meaning of Z3’ can be found in Table 5.4-2 in Section 5.4 of Technical Specification (TS) 38.214.

[0389] In some possible implementations, S860 can include: determining, by the first device, the occupation time of the CPU according to the measurement resource and the first period. The first period can also be referred to as a measurement resource period, a transmission occasion, a period, a reference signal resource period, or other names. The measurement resource can also be referred to as a reference signal resource, an SSB resource, a CSI-RS resource, or other names.

[0390] In example 1-1, the meaning of the first period can be understanding 1, i.e., the first period is a measurement resource period of the measurement resource.

[0391] In example 1-1, the measurement resource can or can not be located in the first resource. In some possible implementations, in the example where the meaning of the first period is understanding 1, there can be no concept of the first resource.

[0392] Some alternative expressions of example 1-1 are introduced below.

[0393] Alternative expression 1 of example 1-1, the occupation time of the CPU includes: from the first time domain unit of the measurement resource in the first period, to the last time domain unit of the measurement resource in the first period, and the first duration after the last time domain unit of the measurement resource in the first period.

[0394] The occupation time of the CPU in the second alternative expression of Example 1-1 includes: from the first time domain unit of a first measurement resource in a first period, until a first duration after the last time domain unit of the first measurement resource in the first period.

[0395] For example, if the time domain unit is a symbol, the first duration is K symbols (K is an integer greater than or equal to 0), and the measurement resource is a CSI-RS / SSB resource in each measurement period (i.e., the first period, or in other words, the measurement resource period of the measurement resource). Wherein the measurement period can be replaced by the transmission occasion. Then, the occupation time of the CPU can include: from the first symbol of the earliest one of each transmission occasion of CSI-RS / SSB resource, until K symbols after the last symbol of the latest one of the CSI-RS / SSB resource in each transmission occasion.

[0396] The third alternative expression of Example 1-1, the occupation time of the CPU is a third duration, the third duration is the duration from the first time domain unit of a measurement resource in a first period to the last time domain unit of the measurement resource in the first period; or the third duration is the duration from the first time domain unit of a measurement resource in a first period to the last time domain unit of the measurement resource in the first period after the last time domain unit.

[0397] In another alternative expression of Example 1-1, the occupation time of the CPU starts from the first symbol of the period or the semi-persistent CSI-RS / SSB resource for event monitoring measurement in the earliest one of each first period (or transmission occasion) and ends after the first duration after the last symbol of the period or the semi-persistent CSI-RS / SSB resource for event monitoring measurement in each first period (or transmission occasion).

[0398] Based on the above scheme, the occupation time of the CPU determined by the first device is short, and the time for processing CSI is saved.

[0399] Some examples of the meaning of the first period for understanding 2 are introduced below, denoted as Example 2-*, where “*” represents a positive integer.

[0400] In understanding 2, the first period includes a time interval between the first transmission occasion and the second transmission occasion, the first transmission occasion and the second transmission occasion being two adjacent transmission occasions in the first resource.

[0401] The measurement resource is located in the first period in the time domain. In other words, the measurement resource is located in a period of the first resource. In other words, the measurement resource is located in the first period in the time domain and is not later than the corresponding CSI reference resource. The first period can be repeated multiple times. For example, Figure 10 (b) of FIG. 1 shows three complete first periods, and each first period has a measurement resource. In other words, Figure 10 (b) of FIG. 1 shows three measurement resources. However, the present application does not limit this, and the first period can have more or fewer numbers.

[0402] The measurement resource in the first period can have one or more measurement resource periods. The measurement resource in the first period can be understood as all measurement resources located in the first period; or can be understood as measurement resources located in the first period and not later than the CSI reference resource. For example, Figure 10 (b) of FIG. 1 shows that the measurement resource in the first period has two measurement resource periods. However, the present application does not limit this, and the measurement resource in the first period can have more or fewer measurement resource periods. The measurement resource in the first period can also not be periodically distributed, or in other words, the measurement resource in the first period can only have one measurement resource period. Those skilled in the art can understand that the measurement resource is periodically distributed at the granularity of multiple first periods, and at the granularity of the first period, or in other words, at the granularity of the measurement resource period, the measurement resource can be periodically distributed or not.

[0403] The last measurement resource period in the at least one measurement resource period of the measurement resource is the second period, or the last measurement resource period in the at least one measurement resource period of the measurement resource that is not later than the corresponding CSI reference resource is the second period. The second period can also be understood as the measurement resource period closest to the transmission occasion of the first resource in the plurality of measurement resource periods of the measurement resource, or as the measurement resource period closest to the transmission occasion of the first resource and not later than the corresponding CSI reference resource in the plurality of measurement resource periods of the measurement resource, or as the measurement resource period closest to the second transmission occasion in the first resource, where the second transmission occasion can be before the first transmission occasion, or as the measurement resource period closest to the second transmission occasion in the first resource and not later than the corresponding CSI reference resource, where the second transmission occasion can be before the first transmission occasion.

[0404] In the case where the measurement resource has only one measurement resource period, the measurement resource period is referred to as the second period.

[0405] Example 2-1: The present application provides a method for determining the occupation time of a CPU. The method comprises: a first device receiving configuration information, the configuration information being used to determine the measurement resource corresponding to the CSI report (or referred to as CSI reporting); and the first device determining the occupation time of the CPU according to the measurement resource and a first period, the occupation time of the CPU being the time during which the first device processes the CSI report and occupies the CPU; wherein the first period comprises a time interval between a first transmission occasion and a second transmission occasion, the first transmission occasion and the second transmission occasion being two adjacent transmission occasions in a first resource, the measurement resource being located in the first period in the time domain, and the first resource being used to transmit information related to the CSI report.

[0406] In (b) of Figure 10 , the start point of the occupation time of the CPU is the first time domain unit (for example, a symbol or an OFDM symbol) of the measurement resource in the first period, and the end point of the occupation time of the CPU is the last time domain unit of the measurement resource in the first period plus a first time length, or the end point of the occupation time of the CPU is the last time domain unit of the measurement resource in the first period and not later than the corresponding CSI reference resource plus the first time length.

[0407] Figure 10 The circle arrows shown in (b) to (e) of Figure 10In the examples of (b) to (e) in the above, the "transmission occasion" can be either a transmission occasion in the first indication resource or a transmission occasion in the first reporting resource. In the case where the first resource is the first indication resource, the period of the first resource is the period of the first indication resource. In the case where the first resource is the first reporting resource, the period of the first resource is the period of the first reporting resource.

[0408] For example, the first period in Example 2-1 can be the period of the first indication resource. In this way, the measurement resource or the measurement resource within the first period can be the measurement resource in one period of the first indication resource, or the measurement resource in one period of the first indication resource no later than the corresponding CSI reference resource. For another example, the first period in Example 2-1 can be the period of the first reporting resource. In this way, the measurement resource or the measurement resource within the first period can be the measurement resource in one period of the first reporting resource, or the measurement resource in one period of the first reporting resource no later than the corresponding CSI reference resource.

[0409] In some possible implementations, S860 can include: determining, by the first device, the occupation time of the CPU according to the measurement resource, wherein the measurement resource is located in the first period. The first period can also be referred to as a reporting resource period, an indication resource period, a transmission occasion, a period, or other names.

[0410] Some alternative expressions of Example 2-1 are introduced below.

[0411] Alternative expression 1 of Example 2-1, the occupation time of the CPU includes: from the first time domain unit of the measurement resource in the first period, to the last time domain unit of the measurement resource in the first period, and the first duration after the last time domain unit of the measurement resource in the first period.

[0412] Alternative expression 2 of Example 2-1, the occupation time of the CPU includes: from the first time domain unit of the first measurement resource in the first period until the first duration after the last time domain unit of the first measurement resource in the first period.

[0413] For example, if the time domain unit is a symbol, the first time length is K symbols (K is an integer greater than or equal to 0), and the measurement resource is the CSI-RS / SSB resource in each first period (i.e., the period of the first indication resource, or the period of the first reporting resource). The first period can be replaced by the transmission occasion. Then, the CPU occupation time can include: from the first symbol of the earliest CSI-RS / SSB resource in each transmission occasion, to K symbols after the last symbol of the latest CSI-RS / SSB resource in each transmission occasion.

[0414] In an alternative expression 3 of Example 2-1, the CPU occupation time is a third time length, which is the time length from the first time domain unit of the measurement resource in the first period to the last time domain unit of the measurement resource in the first period; or the third time length is the time length after the first time domain unit of the measurement resource in the first period to the last time domain unit of the measurement resource in the first period.

[0415] In an alternative expression 4 of Example 2-1, the CPU occupation time is from the first symbol of the earliest periodic or semi-persistent CSI-RS / SSB resource for event monitoring measurement in each first resource period to the first time length after the last symbol of the periodic or semi-persistent CSI-RS / SSB resource for event monitoring measurement in each first resource period (not later than the corresponding CSI reference resource). The first resource can be the first indication resource or the first reporting resource.

[0416] Based on the above scheme, the first device can determine the CPU occupation time according to the measurement resource, and the implementation is simple.

[0417] Example 2-2: The present application provides a method for determining the occupation time of a CPU. The method comprises: a first device receiving configuration information, the configuration information being used to determine a measurement resource corresponding to a CSI report (or referred to as a CSI reporting); and the first device determining, according to the measurement resource and a second period, the occupation time of the CPU, the occupation time of the CPU being the time during which the first device processes the CSI report occupies the CPU; wherein the second period is the last measurement resource period in the measurement resource within a first period, the first period including a time interval between a first transmission occasion and a second transmission occasion, wherein the first transmission occasion and the second transmission occasion are two adjacent transmission occasions in a first resource, the measurement resource being located in the first period in the time domain, and the first resource being used to transmit information related to the CSI report.

[0418] For example, in (c) of the present application, Figure 10 the start point of the occupation time of the CPU is the first time domain unit of the measurement resource in the second period, the end point of the occupation time of the CPU is the last time domain unit of the measurement resource in the second period, and the first time length is added.

[0419] Or, the end point of the occupation time of the CPU is the last time domain unit of the measurement resource (or the second period), and the first time length is added.

[0420] For example, the first period in example 2-2 can be the period of the first indication resource. In this way, the measurement resource or the measurement resource within the first period can be the measurement resource in a period of the first indication resource, or the measurement resource in a period of the first indication resource no later than the corresponding CSI reference resource. The second period can be the last measurement resource period in the measurement resource within the first period, or the second period can be the last measurement resource period in the measurement resource within the first period no later than the corresponding CSI reference resource. For another example, the first period in example 2-2 can be the period of the first reporting resource. In this way, the measurement resource or the measurement resource within the first period can be the measurement resource in a period of the first reporting resource, or the measurement resource in a period of the first reporting resource no later than the corresponding CSI reference resource. The second period can be the last measurement resource period in the measurement resource within the first period, or the second period can be the last measurement resource period in the measurement resource within the first period no later than the corresponding CSI reference resource.

[0421] In some possible implementations, S860 can include that the first device determines the occupation time of the CPU according to the measurement resource and the second period, where the measurement resource is located in the first period, i.e., the measurement resource is a measurement resource in the first period, and the second period is the last measurement resource period in at least one measurement resource period of the measurement resource or the last measurement resource period no later than the corresponding CSI reference resource in at least one period of the measurement resource. The first period can also be referred to as a reporting resource period, an indication resource period, a transmission opportunity, a period, or other names.

[0422] Some alternative expressions of Example 2-2 are introduced as follows.

[0423] Alternative expression 1 of Example 2-2, the occupation time of the CPU includes: from the first time domain unit of the measurement resource in the second period, to the last time domain unit of the measurement resource in the second period, and a first duration after the last time domain unit of the measurement resource in the second period. Or, from the first time domain unit of the measurement resource in the second period, to the last time domain unit of the measurement resource (or the second period), and a first duration after the last time domain unit of the measurement resource (or the second period).

[0424] Alternative expression 2 of Example 2-2, the occupation time of the CPU includes: from the first time domain unit of the measurement resource in the second period, to a first duration after the last time domain unit of the measurement resource in the second period. Or, from the first time domain unit of the measurement resource in the second period, to a first duration after the last time domain unit of the measurement resource (or the second period).

[0425] For example, if the time domain unit is a symbol, the first time length is K symbols (K is an integer greater than or equal to 0), and the measurement resource is the CSI-RS / SSB resource in each second period. Wherein, the second period can be replaced by the transmission occasion. Then, the CPU occupation time can include: from the first symbol of the earliest CSI-RS / SSB resource in each transmission occasion, to K symbols after the last symbol of the latest CSI-RS / SSB resource in each transmission occasion.

[0426] In another alternative expression of example 2-2, the CPU occupation time is a third time length, which is the time length from the first time domain unit of the measurement resource in the second period to the last time domain unit of the measurement resource in the second period; or the third time length is the time length from the first time domain unit of the measurement resource in the second period to the last time domain unit of the measurement resource in the second period after the last time domain unit. Or, the third time length is the time length from the first time domain unit of the measurement resource in the second period to the last time domain unit of the measurement resource (or the second period); or the third time length is the time length from the first time domain unit of the measurement resource in the second period to the last time domain unit of the measurement resource (or the second period) after the last time domain unit.

[0427] In another alternative expression of example 2-2, the CPU occupation time is from the beginning of the earliest one of the periodic or semi-persistent CSI-RS / SSB resources for event monitoring measurement in the nearest measurement resource period (i.e., the second period) before the transmission occasion of each first resource, to the first time length after the last symbol of the periodic or semi-persistent CSI-RS / SSB resource for event monitoring measurement in each second period (not later than the CSI reference resource).

[0428] Alternative Representation 5 of Example 2-2 states that the CPU usage time is the period from the earliest of the event monitoring measurement cycles (i.e., the second cycle) of the corresponding CSI reference resource (i.e., the period before the transmission of each first resource) to the first duration after the last symbol of the event monitoring measurement cycle or the second symbol of the semi-persistent CSI-RS / SSB resource within each second cycle.

[0429] Based on the above scheme, the first device can determine the CPU usage time according to the measured resources, which is simple to implement.

[0430] Example 2-3: This application provides a method for determining CPU occupancy time. The method includes: a first device receiving configuration information, which is used to determine the measurement resource corresponding to a CSI report (or CSI submission); the first device determining the CPU occupancy time based on the measurement resource, a first period, and a second period, wherein the CPU occupancy time is the time the first device occupies the CPU while processing the CSI report; wherein the second period is the last measurement resource period in the measurement resource within the first period, the first period includes the time interval between a first transmission opportunity and a second transmission opportunity, wherein the first transmission opportunity and the second transmission opportunity are two adjacent transmission opportunities in the first resource, the measurement resource is located within the first period in the time domain, and the first resource is used to transmit information related to the CSI report.

[0431] Among them, see Figure 10 In (d), the starting point of the CPU's occupancy time is the first time domain unit of the measurement resource within the second cycle, and the ending point of the CPU's occupancy time is the last time domain unit of the second transmission opportunity (or the first cycle), plus the first duration.

[0432] The second transmission timing occurs after the first transmission timing. For example, the second transmission timing may be located after the first transmission timing in the time domain.

[0433] For example, the first period in example 2-3 can be a period of the first indication resource. In this way, the measurement resource or the measurement resource within the first period can be a measurement resource in a period of the first indication resource, or a measurement resource in a period of the first indication resource no later than the corresponding CSI reference resource. The second period can be a last measurement resource period among the measurement resources within the first period, or the second period can be a last measurement resource period among the measurement resources within the first period no later than the corresponding CSI reference resource. The second transmission occasion can be a transmission occasion in the first indication resource. For another example, the first period in example 2-3 can be a period of the first reporting resource. In this way, the measurement resource or the measurement resource within the first period can be a measurement resource in a period of the first reporting resource, or a measurement resource in a period of the first reporting resource no later than the corresponding CSI reference resource. The second period can be a last measurement resource period among the measurement resources within the first period, or the second period can be a last measurement resource period among the measurement resources within the first period no later than the corresponding CSI reference resource. The second transmission occasion can be a transmission occasion in the first reporting resource.

[0434] In some possible implementations, S860 can include that the first device determines the occupation time of the CPU according to the measurement resource, the second period, or the first period (i.e., a period of the first resource), where the measurement resource is located in the first period, i.e., the measurement resource is a measurement resource within the first period, and the second period is a last measurement resource period among at least one measurement resource period of the measurement resource or a last measurement resource period among at least one measurement resource period of the measurement resource no later than the corresponding CSI reference resource. The first period can also be referred to as a reporting resource period, an indication resource period, a transmission occasion, a period, or other names.

[0435] Some alternative expressions of example 2-3 are introduced below.

[0436] Alternative expression 1 of example 2-3, the occupation time of the CPU includes: from a first time domain unit of the measurement resource within the second period, to a last time domain unit of the second transmission occasion (or the first period), and a first time length after the last time domain unit of the second transmission occasion (or the first period).

[0437] Example 2-3, the CPU occupancy time includes: from the first time domain unit of a first measurement resource in a second period until a first duration after the last time domain unit of a second transmission occasion [or a first period].

[0438] Example 2-3, the CPU occupancy time is a third duration, the third duration is a duration from the first time domain unit of a first measurement resource in a second period until the last time domain unit of a second transmission occasion [or a first period]; or, the third duration is a duration from the first time domain unit of a first measurement resource in a second period until after the last time domain unit of a second transmission occasion [or a first period].

[0439] Example 2-3, the CPU occupancy time is a first symbol of a first resource in each first period, or a first symbol of a first resource in each first period plus a first duration.

[0440] Example 2-3, the CPU occupancy time is a first symbol of a first resource in each first period, or a first symbol of a first resource in each first period plus a first duration.

[0441] Example 2-3 can be applied to a second period, i.e., the last measurement resource period in the at least one measurement resource period of the measurement resource is the second period, or the last measurement resource period in the at least one measurement resource period of the measurement resource is not later than the corresponding CSI reference resource. For example, the measurement resource can include multiple measurement resource periods, and example 2-3 is only applicable to the last measurement resource period of the measurement resource. For other measurement resource periods of the measurement resource other than the second period (or in other words, other than the last period), example 1-1 can be applicable. In other words, in the case that a certain period of the measurement resource is not the closest period to the transmission occasion of the first resource, or a certain period of the measurement resource is not the closest period to the transmission occasion of the first resource and is not later than the corresponding CSI reference resource, the CPU occupation time adopts the calculation manner of example 1-1. In the case that a certain period of the measurement resource is the closest period to the transmission occasion of the first resource, or a certain period of the measurement resource is the closest period to the transmission occasion of the first resource and is not later than the corresponding CSI reference resource, the end (or termination) time of the CPU occupation time can be the last symbol of the adjacent transmission occasion of the first resource, or the last symbol of the transmission occasion of the first resource plus the first time length.

[0442] Based on the above scheme, the first device can determine the occupation time of the CPU according to the period of the first resource (understood as the first period), and the implementation is simple.

[0443] Optionally, in the above scheme, the measurement resource in the second period, or in other words, the earliest one of the periods for event monitoring measurement or the semi-persistent CSI-RS / SSB resource before the closest measurement resource period (i.e., the second period) of each transmission occasion of the first resource, is not later than the corresponding CSI reference resource.

[0444] Example 2-4: The present application provides a method for determining the occupation time of a CPU. The method comprises: a first device receiving configuration information, the configuration information being used to determine a measurement resource corresponding to a CSI report (or referred to as a CSI report); the first device determining the occupation time of the CPU according to the measurement resource and a first period, the occupation time of the CPU being the time during which the first device processes the CSI report and occupies the CPU; wherein the first period includes a time interval between a first transmission occasion and a second transmission occasion, the first transmission occasion and the second transmission occasion being two adjacent transmission occasions in a first resource, the measurement resource being located in the first period in the time domain, and the first resource being used to transmit information related to the CSI report.

[0445] Wherein, see Figure 10(e) in the first period, the start of the CPU occupation time is the first time domain unit of the measurement resource, the end of the CPU occupation time is the last time domain unit of the second sending occasion (or the first period), and the first time length is added.

[0446] The second sending occasion is after the first sending occasion in the time domain.

[0447] For example, the first period in example 2-4 can be the period of the first indication resource. In this way, the measurement resource or the measurement resource in the first period can be the measurement resource in a period of the first indication resource, or the measurement resource in a period of the first indication resource no later than the corresponding CSI reference resource. The second sending occasion can be a sending occasion in the first indication resource. For another example, the first period in example 2-4 can be the period of the first reporting resource. In this way, the measurement resource or the measurement resource in the first period can be the measurement resource in a period of the first reporting resource, or the measurement resource in a period of the first reporting resource no later than the corresponding CSI reference resource. The second sending occasion can be a sending occasion in the first reporting resource.

[0448] In some possible implementations, S860 can include that the first device determines the occupation time of the CPU according to the measurement resource, the second period or the first period (i.e., the period of the first resource), wherein the measurement resource is in the first period, i.e., the measurement resource is the measurement resource in the first period, and the second period is the last measurement resource period in at least one measurement resource period of the measurement resource or the last measurement resource period no later than the corresponding CSI reference resource in at least one period of the measurement resource. The first period can also be referred to as a reporting resource period, an indication resource period, a sending occasion, a period, or other names.

[0449] Some alternative expressions of example 2-4 are introduced below.

[0450] Alternative expression 1 of example 2-4, the occupation time of the CPU includes: from the first time domain unit of the measurement resource in the first period, to the last time domain unit of the second sending occasion (or the first period), and the first time length after the last time domain unit of the second sending occasion (or the first period).

[0451] In an alternative expression 2 of Example 2-4, the CPU occupation time includes: from the first time domain unit of the first measurement resource in the first period until a first duration after the last time domain unit of the second transmission occasion (or the first period).

[0452] In an alternative expression 3 of Example 2-4, the CPU occupation time is a third duration, which is a duration from the first time domain unit of the measurement resource in the first period to the last time domain unit of the second transmission occasion (or the first period), or a duration from the first time domain unit of the measurement resource in the first period to after the last time domain unit of the second transmission occasion (or the first period).

[0453] In an alternative expression 4 of Example 2-4, the CPU occupation time is from the beginning of the first symbol of the earliest one of the periodic or semi-persistent CSI-RS / SSB resources for event monitoring measurement in each first period to the last symbol of the first resource of each first period, or the last symbol of the first resource of each first period plus a first duration.

[0454] In an alternative expression 5 of Example 2-4, the CPU occupation time is from the beginning of the first symbol of the earliest one of the periodic or semi-persistent CSI-RS / SSB resources (not later than the corresponding CSI reference resource) for event monitoring measurement in each first period to the last symbol of the first resource of each first period, or the last symbol of the first resource of each first period plus a first duration.

[0455] Based on the above scheme, the first device can determine the CPU occupation time according to the period of the first resource (understood as the first period), and the implementation is simple.

[0456] Optionally, in the above scheme, the measurement resource in the first period is not later than the corresponding CSI reference resource.

[0457] In the case where the period of the first resource and the measurement resource period of the measurement resource are the same, or in the case where the measurement resource in the first period only includes one period, Example 2-1 and Example 2-2 are equivalent, and Example 2-3 and Example 2-4 are equivalent. That is, Figure 10(b) and (c) in (a) are equivalent, Figure 10 (d) and (e) in (a) are equivalent.

[0458] The above-mentioned example 1-1, example 2-1, example 2-2, example 2-3 and example 2-4 can be applied to Mode A, and can also be applied to Mode B.

[0459] The following describes example 2-5 and example 2-6, which can be applied to Mode A. As shown in (f) and (g) in (a), the first period can be a time domain unit between the third transmission occasion of sending the first information and the nearest transmission occasion before the third transmission occasion. Other descriptions can refer to the previous description of the first period. For example, the first period can also include the nearest transmission occasion before the third transmission occasion, and the time domain unit to the third transmission occasion. Figure 10

[0460] Example 2-5: The present application provides a method for determining the occupation time of a CPU. The method comprises: a first device receiving configuration information, the configuration information being used to determine a measurement resource corresponding to a CSI report (or referred to as CSI reporting); the first device determining the occupation time of the CPU according to the measurement resource, a second period and a second reporting resource, the occupation time of the CPU being the time during which the first device processes the CSI report and occupies the CPU; wherein the second period is the last measurement resource period in the measurement resource within the first period, the first period comprising a time interval between a first transmission occasion and a second transmission occasion, wherein the first transmission occasion and the second transmission occasion are two adjacent transmission occasions in a first indication resource, the measurement resource being located in the first period in the time domain, and the first indication resource being used to send information related to the CSI report, wherein the second reporting resource is a resource of the CSI report indicated by a second device. For example, the first device can receive second information from the second device, the second information being used to indicate the second reporting resource of sending the CSI report.

[0461] Wherein, referring to Figure 10 As shown in (f) in (a), the starting point of the occupation time of the CPU is the first time domain unit of the measurement resource within the second period, the ending point of the occupation time of the CPU is the last time domain unit of the second reporting resource, and a first time length is added. The measurement resource is periodic or semi-persistent. Figure 10 As shown in (f) in (a), the starting point of the occupation time of the CPU is the first time domain unit of the measurement resource within the second period, the ending point of the occupation time of the CPU is the last time domain unit of the second reporting resource, and a first time length is added. The measurement resource is periodic or semi-persistent.

[0462] ​For example, the first period in example 2-5 can be a period of the first indication resource. In this way, the measurement resource or the measurement resource within the first period can be a measurement resource in a period of the first indication resource, or a measurement resource in a period of the first indication resource no later than the corresponding CSI reference resource. The second period can be a last measurement resource period among the measurement resources within the first period, or the second period can be a last measurement resource period among the measurement resources within the first period no later than the corresponding CSI reference resource. For another example, the first period in example 2-5 can be a period of the first report resource. In this way, the measurement resource or the measurement resource within the first period can be a measurement resource in a period of the first report resource, or a measurement resource in a period of the first report resource no later than the corresponding CSI reference resource. The second period can be a last measurement resource period among the measurement resources within the first period, or the second period can be a last measurement resource period among the measurement resources within the first period no later than the corresponding CSI reference resource.

[0463] In some possible implementations, S860 can include that the first device determines the occupation time of the CPU according to the measurement resource, the second period, or the second report resource, where the measurement resource is located in the first period, i.e., the measurement resource is the measurement resource within the first period, and the second period is a last measurement resource period among at least one measurement resource period of the measurement resource or a last measurement resource period among at least one period of the measurement resource no later than the corresponding CSI reference resource. The first period can also be referred to as a report resource period, an indication resource period, a transmission occasion, a period, or other names.

[0464] Some alternative expressions of example 2-5 are introduced as follows.

[0465] Alternative expression 1 of example 2-5, the occupation time of the CPU includes: from a first time domain unit of the measurement resource in the second period, to a last time domain unit of the second report resource, and a first duration after the last time domain unit of the second report resource.

[0466] Alternative expression 2 of example 2-5, the occupation time of the CPU includes: from a first time domain unit of a first measurement resource in a second period until a first duration after the last time domain unit of a second report resource.

[0467] In an alternative expression of Example 2-5, the CPU occupation time is a third time length, which is a time length from a first time domain unit of the measurement resource in the second period to a last time domain unit of the second reporting resource; or the third time length is a time length from the first time domain unit of the measurement resource in the second period to a time after the last time domain unit of the second reporting resource.

[0468] In an alternative expression of Example 2-5, the CPU occupation time is a first time length from a beginning of a first symbol of a nearest and no later than a first measurement resource period (i.e., a second period) of a corresponding CSI reference resource to a last symbol of the scheduled reporting resource after a first period in the first period before a sending time of the first resource.

[0469] In an alternative expression of Example 2-5, the CPU occupation time is a first time length from a beginning of a first symbol of a nearest measurement resource period (i.e., a second period) to a last symbol of the scheduled reporting resource after a first period in the first period before a sending time of the first resource.

[0470] Based on the above scheme, the first device can determine the CPU occupation time according to the resource (i.e., the second reporting resource) indicated by the second device for the CSI report, which is simple in implementation.

[0471] Example 2-6: The present application provides a method for determining CPU occupation time. The method comprises: a first device receives configuration information, the configuration information being used to determine measurement resource corresponding to CSI report (or referred to as CSI reporting); the first device determines the CPU occupation time according to the measurement resource, a first period and a second reporting resource, the CPU occupation time being a time at which the first device processes the CSI report occupies the CPU; wherein the first period comprises a time interval between a first sending time and a second sending time, wherein the first sending time and the second sending time are two adjacent sending times in a first indication resource, the measurement resource being located in the first period in time domain, the first indication resource being used to send information related to the CSI report, wherein the second reporting resource is a resource of the CSI report indicated by a second device. For example, the first device can receive second information from the second device, the second information being used to indicate the second reporting resource for sending the CSI report.

[0472] Wherein, referring to Figure 11(g) in the (g), the start point of the CPU occupation time is the first time domain unit of the measurement resource, the end point of the CPU occupation time is the last time domain unit of the second report resource, and the first duration is added. The measurement resource is periodic or semi-persistent. Figure 11 (f) in the (f) is taken as an example, and the literal description of the embodiments of the present application is used as a reference.

[0473] For example, the first period in example 2-6 can be the period of the first indication resource. In this way, the measurement resource or the measurement resource in the first period can be the measurement resource in a period of the first indication resource, or the measurement resource in a period of the first indication resource no later than the corresponding CSI reference resource. For another example, the first period in example 2-6 can be the period of the first report resource. In this way, the measurement resource or the measurement resource in the first period can be the measurement resource in a period of the first report resource, or the measurement resource in a period of the first report resource no later than the corresponding CSI reference resource.

[0474] In some possible implementations, S860 can include that the first device determines the occupation time of the CPU according to the measurement resource or the second report resource, wherein the measurement resource is located in the first period, that is, the measurement resource is the measurement resource in the first period. The first period can also be referred to as a report resource period, an indication resource period, a sending opportunity, a period, or other names.

[0475] Some alternative expressions of example 2-6 are introduced below.

[0476] Alternative expression 1 of example 2-6, the occupation time of the CPU includes: from the first time domain unit of the measurement resource, to the last time domain unit of the second report resource, and a first duration after the last time domain unit of the second report resource.

[0477] Alternative expression 2 of example 2-6, the occupation time of the CPU includes: from the first time domain unit of the first measurement resource until a first duration after the last time domain unit of the second report resource.

[0478] In the third aspect, the occupation time of the CPU is a third time length, the third time length being a time length from a first time domain unit of the measurement resource to a last time domain unit of the second reporting resource; or the third time length being a time length after the first time domain unit of the measurement resource to the last time domain unit of the second reporting resource.

[0479] In the fourth aspect, the occupation time of the CPU is a first time length from a start of a first symbol of an earliest one of the periodic or semi-persistent CSI-RS / SSB resources (not later than the CSI reference resource) for event monitoring measurement in the first period to after a last symbol of the scheduled reporting resource.

[0480] In the fifth aspect, the occupation time of the CPU is a first time length from a start of a first symbol of an earliest one of the periodic or semi-persistent CSI-RS / SSB resources for event monitoring measurement in the first period to after a last symbol of the scheduled reporting resource. Based on the above scheme, the first device can determine the occupation time of the CPU according to the resource (i.e., the second reporting resource) for CSI reporting indicated by the second device, and the implementation is simple.

[0481] Figure 11 are another schematic diagram of the occupation time of the CPU provided by the embodiments of the present application. The following describes another example of the occupation time of the CPU determined by S860. Figure 11 The following describes another example of the occupation time of the CPU determined by S860. Figure 11 The examples shown are applicable to Mode A and Mode B.

[0482] In the related description of Figure 11 , the measurement resource can be aperiodic resource or semi-persistent resource associated with event triggered reporting. For example, the measurement resource can be aperiodic distributed resource. For another example, the measurement resource can be a resource in a period (i.e., a first period triggered in the semi-persistent resource) triggered by DCI in the semi-persistent resource.

[0483] For the related example, the meaning of the first period is understanding 2. That is, the first period is a period of the first resource. Figure 11

[0484] Exemplarily, the measurement resource in the first period can include CSI-RS resource and / or SSB resource.

[0485] In some possible implementation manners, the method further includes 800: S820, the first device receives third information from the second device on the second indication resource, the third information being used for triggering measurement of the measurement resource. Correspondingly, the second device sends the third information to the second device on the second indication resource.

[0486] ​Exemplarily, S820 can be performed before S860. The present application does not limit the execution order of S805, S810 and S820. For example, S820 can be performed before or after S810.

[0487] Optionally, the second indication resource is a PDCCH. However, the present application does not limit this, for example, the second indication resource can also be other resources.

[0488] Exemplarily, the third information can be DCI. However, the present application does not limit this, for example, the third information can also be a MAC CE or other information. In addition to triggering the measurement of the measurement resource, the third information can also trigger the measurement of other measurement resources. For example, the third information can trigger the measurement of multiple measurement resources related to CSI reporting. Among them, the measurement resource is part of the multiple measurement resources related to CSI reporting. In other examples, the measurement resource can be all of the multiple measurement resources related to CSI reporting.

[0489] In Figure 11 In the example shown, the start of the occupation time of the CPU is the first time domain unit after the second indication resource, the end of the occupation time of the CPU is the last time domain unit of the fifth sending occasion in the first resource, and the first time length is added.

[0490] Among them, the fifth sending occasion can be the first of at least one sending occasion in the first resource after the second time length after the measurement resource. Alternatively, the fifth sending occasion can be the last symbol of the sending occasion in the first resource after the first symbol after the measurement resource experiences Y symbols. Among them, Y is a non-negative integer.

[0491] For example, the first resource described above can be the first indication resource. In this way, the fifth sending occasion can be a sending occasion in the first resource.

[0492] The measurement resource or the measurement resource in the first period can be a measurement resource in a period of the first indication resource, or a measurement resource no later than the corresponding CSI reference resource in a period of the first indication resource. The second period can be a last measurement resource period among the measurement resources in the first period, or the second period can be a last measurement resource period no later than the corresponding CSI reference resource among the measurement resources in the first period. The second transmission occasion can be a transmission occasion in the first indication resource. For example, the first period in the example 2-3 can be a period of the first reporting resource. In this way, the measurement resource or the measurement resource in the first period can be a measurement resource in a period of the first reporting resource, or a measurement resource no later than the corresponding CSI reference resource in a period of the first reporting resource. The second period can be a last measurement resource period among the measurement resources in the first period, or the second period can be a last measurement resource period no later than the corresponding CSI reference resource among the measurement resources in the first period. The second transmission occasion can be a transmission occasion in the first reporting resource.

[0493] The second duration can be expressed in one or more time domain units (e.g., symbols or OFDM symbols), and the second duration can also be zero.

[0494] For example, referring to (a) or (c) in Figure 11 , the second duration can be 0 or other small values, so that the fifth transmission occasion is the first transmission occasion after the first period. In this case, the fifth transmission occasion can also be represented as the second transmission occasion.

[0495] For example, referring to (b) or (d) in Figure 11 , the second duration can be the length shown by the dashed line.

[0496] Some alternative expressions of the examples shown in Figure 11 are introduced as follows:

[0497] Alternative expression 1: The occupation time of the CPU includes: from the first time domain unit after the second indication resource, to the last time domain unit of the fifth transmission occasion in the first resource, and the first duration after the last time domain unit of the fifth transmission occasion in the first resource.

[0498] In the second expression, the CPU occupation time includes: a first duration from a first time domain unit after a second indicating resource until a last time domain unit of a fifth transmission occasion in a first resource.

[0499] In the third expression, the CPU occupation time is a third duration, which is a duration from a first time domain unit after the second indicating resource until a last time domain unit of the fifth transmission occasion in the first resource, or which is a duration from the first time domain unit after the second indicating resource until after the last time domain unit of the fifth transmission occasion in the first resource.

[0500] In a case where the second duration is 0 or other small value, the fifth transmission occasion in the first resource can be replaced by a first period.

[0501] In some possible implementation manners, the second indicating resource is located within the first period in time domain. For example, Figure 10 (a) or (b) in the first expression. In some other possible implementation manners, the second indicating resource is located before the first period in time domain. For example, Figure 11 (c) or (d) in the first expression.

[0502] In some possible implementation manners, the measurement resource is not later than a corresponding CSI reference resource. The CSI reference resource can be referred to a related scheme.

[0503] The above introduces an example of the determined CPU occupation time. Figure 10 and Figure 11 The above introduces an example of the determined CPU occupation time.

[0504] The embodiment of the present application further provides a method for determining CPU occupation time. The method comprises: a first device receiving configuration information, the configuration information being used for determining measurement resource corresponding to CSI reporting (or referred to as CSI reporting); and the first device determining CPU occupation time, the CPU occupation time being time occupied by the first device in processing the CSI reporting. Wherein, the period of the first indication resource comprises a time interval between a first sending occasion and a second sending occasion, the first sending occasion and the second sending occasion being two adjacent sending occasions in the first indication resource, and the measurement resource is located in the period of the first indication resource in the time domain.

[0505] Wherein, the first indication resource is used for sending first information, the third sending occasion is a sending occasion of the first information in the first indication resource, the first reporting resource is used for sending the CSI reporting, the fourth sending occasion is a sending occasion of the CSI reporting in the first reporting resource, and the first information is used for indicating that the fourth sending occasion associated with the third sending occasion exists the CSI reporting or whether the fourth sending occasion associated with the third sending occasion exists the CSI reporting.

[0506] Or, wherein, the first indication resource is used for sending the first information, and the first information is used for requesting the resource of the CSI reporting.

[0507] Wherein, the start point of the CPU occupation time can be a first time domain unit of the measurement resource in the period of the first indication resource, or the start point of the CPU occupation time can be a first time domain unit of the measurement resource in a second period, the second period being a last measurement resource period in at least one measurement resource period.

[0508] Wherein, in the case that the first device does not send the first information, the end point of the CPU occupation time can be a last symbol of the second sending occasion in the first indication resource, plus a first time length.

[0509] Or, wherein, in the case that the first device sends the first information and the first information is used for indicating that the fourth sending occasion does not exist the CSI reporting, the end point of the CPU occupation time can be a last symbol of the second sending occasion in the first indication resource, plus a first time length, the second sending occasion being the third sending occasion.

[0510] Or, wherein, in the case that the first device sends the first information and the first information is used for indicating that the fourth sending occasion exists the CSI reporting, the end point of the CPU occupation time can be a last symbol of the fourth sending occasion in the first reporting resource, plus a first time length.

[0511] Or, in the case where the first device transmits the first information, and the first information is used to request a resource scheduled for the CSI report, the end of the CPU occupation time is the last symbol of the second reporting resource (or, the scheduled resource) plus the first time length, where the second reporting resource is the resource for the CSI report indicated by the second device. For example, the first device can receive the second information from the second device, where the second information is used to indicate the second reporting resource for transmitting the CSI report.

[0512] The following describes some ways of dynamically determining the CPU occupation time, denoted as dynamic way 1, dynamic way 2, dynamic way 3, and dynamic way 4. Figure 12 And Figure 12 The following describes some ways of dynamically determining the CPU occupation time, denoted as dynamic way 1, dynamic way 2, dynamic way 3, and dynamic way 4.

[0513] Dynamic way 1: In the case where the first device does not transmit the first information, the first resource is the first indicated resource.

[0514] For example, the first device does not transmit the first information at the transmission occasion (e.g., the second transmission occasion) in the first indicated resource, and then the first resource in the CPU occupation time can be the first indicated resource.

[0515] In some examples, dynamic way 1 can be applicable to example 2-1, example 2-2, example 2-3, and example 2-4. In the above examples, the first resource is the first indicated resource. For example, the measurement resource is located in the period of the first indicated resource (i.e., the first period), or in other words, the measurement resource is located in the period of the first indicated resource (i.e., the first period) and no later than the corresponding CSI reference resource. For another example, in example 2-3 and example 2-4, the end of the CPU occupation time is the transmission occasion (e.g., the second transmission occasion) of the first indicated resource plus the first time length.

[0516] In some examples, the start of the CPU occupancy time can be the first symbol of the earliest one of the first periodicity for event monitoring measurement or the first periodicity of the semi-persistent CSI-RS / SSB resource in each first periodicity. In some examples, the start of the CPU occupancy time can be the first symbol of the earliest one of the first periodicity for event monitoring measurement or the first periodicity of the semi-persistent CSI-RS / SSB resource in each first periodicity, which is no later than the corresponding CSI reference resource. In some examples, the start of the CPU occupancy time can be the first symbol of the earliest one of the first periodicity for event monitoring measurement or the first periodicity of the semi-persistent CSI-RS / SSB resource in each first periodicity, which is the nearest one before the transmission occasion of the first indication resource (i.e., the second transmission occasion). In some examples, the start of the CPU occupancy time can be the first symbol of the earliest one of the first periodicity for event monitoring measurement or the first periodicity of the semi-persistent CSI-RS / SSB resource in each first periodicity, which is the nearest one and no later than the corresponding CSI reference resource before the transmission occasion of the first indication resource (i.e., the second transmission occasion). The end of the CPU occupancy time can be the last symbol of the transmission occasion (e.g., the second transmission occasion) of the first indication resource in the first periodicity of the first indication resource, plus the first time duration.

[0517] Dynamic manner 2: In the case that the first device transmits the first information, and the first information is used to indicate that the fourth transmission occasion does not exist the CSI report, the first resource is the first indication resource, and the second transmission occasion is the third transmission occasion.

[0518] For example, the first device transmits the first information at the transmission occasion (e.g., the third transmission occasion) in the first indication resource, but the first information is used to indicate that the associated transmission occasion (e.g., the fourth transmission occasion) does not exist the CSI report and / or indicate that no event occurs, then the first resource in the CPU occupancy time can be the first indication resource.

[0519] In some examples, dynamic manner 2 can be applied to example 2-1, example 2-2, example 2-3 and example 2-4. In the above examples, the first resource is the first indication resource. For example, the measurement resource is located in the first periodicity (i.e., the first periodicity) of the first indication resource, or the measurement resource is located in the first periodicity (i.e., the first periodicity) of the first indication resource and no later than the corresponding CSI reference resource. For another example, in example 2-3 and example 2-4, the end of the CPU occupancy time is the transmission occasion (e.g., the second transmission occasion) of the first indication resource, plus the first time duration.

[0520] In some examples, the start of the CPU occupancy time can be the first symbol of the earliest one of the periodic (i.e., first periodic) first indication resources or the periodic (i.e., first periodic) CSI reference resources for event monitoring measurement, or the start of the CPU occupancy time can be the first symbol of the earliest one of the periodic (i.e., first periodic) first indication resources or the periodic (i.e., first periodic) CSI reference resources for event monitoring measurement no later than the corresponding CSI reference resources. Or, the start of the CPU occupancy time can be the first symbol of the earliest one of the measurement resource periods (i.e., second periodic) no later than the transmission occasion of the periodic (i.e., first periodic) first indication resources, or the start of the CPU occupancy time can be the first symbol of the earliest one of the measurement resource periods (i.e., second periodic) no later than the transmission occasion of the periodic (i.e., first periodic) first indication resources and no later than the corresponding CSI reference resources. The end of the CPU occupancy time can be the last symbol of the transmission occasion of the periodic (i.e., first periodic) first indication resources plus the first time duration.

[0521] Dynamic manner 3: In the case that the first device transmits the first information, and the first information is used to indicate that the CSI report exists in the fourth transmission occasion, the first resource is the first reporting resource, and the second transmission occasion is the fourth transmission occasion.

[0522] Exemplarily, the first device transmits the first information at the transmission occasion (e.g., the third transmission occasion) in the first indication resource, and the first information is used to indicate that the associated transmission occasion (e.g., the fourth transmission occasion) exists the CSI report (i.e., the case of Mode B) and / or indicate that the event occurs, then the first resource in the CPU occupancy time can be the first reporting resource.

[0523] In some examples, the dynamic manner 3 can be applied to example 2-1, example 2-2, example 2-3, and example 2-4. In the above examples, the first resource is the first reporting resource. For example, the measurement resource is in the period (i.e., the first period) of the first reporting resource, or the measurement resource is in the period (i.e., the first period) of the first reporting resource and no later than the corresponding CSI reference resource. For another example, in example 2-3 and example 2-4, the end of the CPU occupancy time is the transmission occasion (e.g., the second transmission occasion, or referred to as the fourth transmission occasion herein) of the first reporting resource plus the first time duration.

[0524] In some examples, the start of the CPU occupancy time can be the first symbol of the earliest one of the periodic (i.e., first periodic) measurement resource or the first symbol of the semi-persistent CSI-RS / SSB resource in the period (i.e., first periodic) of each first reporting resource. In other examples, the start of the CPU occupancy time can be the first symbol of the earliest one of the periodic (i.e., first periodic) measurement resource or the first symbol of the semi-persistent CSI-RS / SSB resource in the period (i.e., first periodic) of each first reporting resource, and the measurement resource is no later than the corresponding CSI reference resource. In other examples, the start of the CPU occupancy time can be the first symbol of the earliest one of the periodic (i.e., first periodic) measurement resource or the first symbol of the semi-persistent CSI-RS / SSB resource in the nearest one of the measurement resource periods (i.e., second periodic) before the transmission occasion of each first reporting resource. In other examples, the start of the CPU occupancy time can be the first symbol of the earliest one of the periodic (i.e., first periodic) measurement resource or the first symbol of the semi-persistent CSI-RS / SSB resource in the nearest one of the measurement resource periods (i.e., second periodic) before the transmission occasion of each first reporting resource, and the measurement resource is no later than the corresponding CSI reference resource. The end of the CPU occupancy time can be the last symbol of the transmission occasion of the first reporting resource in the period of each first reporting resource, plus the first duration.

[0525] In other possible implementations, the measurement resource is not located in the period (i.e., first periodic) of the first reporting resource, but is located in the period (i.e., third periodic) of the first indication resource. The above scheme is referred to as dynamic mode 3', which is described in detail below.

[0526] In some examples, the start of the CPU occupancy time can be the first symbol of the measurement resource in the third periodic, or the start of the CPU occupancy time can be the first symbol of the measurement resource in the third periodic, and the measurement resource is no later than the corresponding CSI reference resource. In other examples, the start of the CPU occupancy time can be the first symbol of the measurement resource in the fourth periodic, or the start of the CPU occupancy time can be the first symbol of the measurement resource in the fourth periodic, and the measurement resource is no later than the corresponding CSI reference resource. The fourth periodic can be the last one of the at least one measurement resource period.

[0527] In some examples, the end of the CPU occupancy time can be the transmission occasion (e.g., second transmission occasion, or referred to as fourth transmission occasion herein) of the first reporting resource.

[0528] An alternative description can be: the start of the CPU occupation time can be the earliest one of the periods for event monitoring measurement or the first symbol of the semi-persistent CSI-RS / SSB resource within the period (i.e., the third period here) of each first indication resource, or the earliest one of the periods for event monitoring measurement or the first symbol of the semi-persistent CSI-RS / SSB resource no later than the corresponding CSI reference resource within the period (i.e., the third period here) of each first indication resource. Alternatively, the start of the CPU occupation time can be the earliest one of the periods for event monitoring measurement or the first symbol of the semi-persistent CSI-RS / SSB resource of the nearest one of the periods (i.e., the fourth period here) before the transmission occasion of each first indication resource, or the earliest one of the periods for event monitoring measurement or the first symbol of the semi-persistent CSI-RS / SSB resource no later than the corresponding CSI reference resource within the nearest one of the periods (i.e., the fourth period here) before the transmission occasion of each first indication resource. The end of the CPU occupation time can be the last symbol of the transmission occasion of the first reporting resource within the period (i.e., the first period here) of each first reporting resource, plus the first time length.

[0529] Among them, dynamic mode 3 and dynamic mode 3' can be compatible, for example, the measurement resource is located in the period of the first indication resource (corresponding to dynamic mode 3') and the period of the first reporting resource (corresponding to dynamic mode 3). Dynamic mode 3 and dynamic mode 3' can also be incompatible, for example, the measurement resource is only located in the period of the first indication resource, or only located in the period of the first reporting resource.

[0530] Dynamic mode 4: in the case that the first device transmits the first information, and the first information is used to request to schedule resources for the CSI report, the end of the CPU occupation time is the last symbol of the second reporting resource (or called, scheduled resource), plus the first time length.

[0531] Exemplarily, the first device transmits the first information at the transmission occasion (for example, the third transmission occasion) in the first indication resource, and the first information is used to request to schedule resources for the CSI report (i.e., the case of Mode A), then the end of the CPU occupation time can be the last symbol of the resource scheduled by the second device, plus the first time length.

[0532] In some examples, dynamic mode 4 can be applicable to examples 2-5 and 2-6. In the above examples, the first resource is the first indication resource. For example, the measurement resource is located in the period (i.e., the first period) of the first indication resource, or the measurement resource is located in the period (i.e., the first period) of the first indication resource and no later than the corresponding CSI reference resource.

[0533] In other examples, the start point of CPU occupancy may be the earliest event monitoring measurement cycle or the first symbol of a semi-persistent CSI-RS / SSB resource within each first cycle, or no later than the earliest event monitoring measurement cycle or the first symbol of a semi-persistent CSI-RS / SSB resource within each first cycle. Alternatively, the start point of CPU occupancy may be the earliest event monitoring measurement cycle or the first symbol of a semi-persistent CSI-RS / SSB resource within the most recent measurement resource cycle (i.e., the second cycle) preceding the transmission of each first reporting resource, or no later than the earliest event monitoring measurement cycle or the first symbol of a semi-persistent CSI-RS / SSB resource within the most recent measurement resource cycle (i.e., the second cycle) preceding the transmission of each first reporting resource. The end point of CPU occupancy may be the last symbol of a second reporting resource scheduled by the second device, plus a first duration.

[0534] The second reporting resource may be referred to as the scheduling reporting resource, the uplink resource for the bearer report, the bearer report resource, the uplink resource, the resource, or other names. For example, the second reporting resource may be a PUSCH resource.

[0535] In some possible implementations, the first device can determine the CPU usage time according to one of dynamic methods 1, 2, 3, 3', or 4, based on whether the first information is sent and the content indicated by the first information.

[0536] Figure 12 This is a schematic diagram illustrating the dynamic determination of CPU usage time provided in an embodiment of this application. Figure 12 In (a) of the figure, the sending of the first information and the first information used to indicate that the fourth sending time has a CSI report (marked with the word "indication" in the figure) is indicated by a bold arrow; and the fourth sending time (marked with the word "reporting" in the figure) is indicated by a bold dashed box. Figure 12 In (b) of the diagram, the sending of the first message, which requests the timing of the dispatch of resources for sending CSI reports (labeled "Request" in the diagram), is indicated by a bold arrow. The resource for receiving the second message is labeled "Dispatch." This second message indicates the second reporting resource for sending CSI reports (labeled "Report" in the diagram and indicated by a solid bold box).

[0537] See Figures 13 to 16 In (a), as an alternative expression of the above dynamic modes 1, 2, 3 and 3', the end point of CPU occupancy time is: the last symbol of the first indicator resource transmission timing in each first indicator resource cycle, plus the fourth duration.

[0538] In the case that the first device does not send the first information (i.e., the reporting indication or the scheduling request) at the transmission occasion of the first indication resource, or in the case that the first device sends the first information at the transmission occasion of the first indication resource and the first information is used to indicate that there is no CSI report at the fourth transmission occasion and / or there is no event, the fourth time duration is the first time duration. For example, the fourth time duration is one or more time domain units. For another example, the fourth time duration is 0 or Z3' symbols. This case corresponds to the dynamic mode 1 and the dynamic mode 2.

[0539] In the case that the first device sends the first information at the transmission occasion of the first indication resource and the first information is used to indicate that there is a CSI report at the fourth transmission occasion and / or there is an event (i.e., Mode B), the fourth time duration is the interval between the last symbol of the third transmission occasion and the last symbol of the fourth transmission occasion, plus the first time duration. Alternatively, the fourth time duration is the time interval between the transmission occasion of the first reporting resource and the transmission occasion of the corresponding first indication resource. Alternatively, the fourth time duration is the difference of the offset of the first reporting resource of the period and the offset of the first indication resource of the period. Alternatively, the fourth time duration is the time interval between the occasion of sending the first information and the occasion of sending the CSI report. This case corresponds to the dynamic mode 3 or the dynamic mode 3'.

[0540] Referring to (b) in Figure 13 As an alternative expression of the dynamic modes 1, 2 and 4, the end of the CPU occupation time is the last symbol of the transmission occasion of the first indication resource in each period of the first indication resource, plus the fifth time duration.

[0541] In the case that the first device does not send the first information (i.e., the reporting indication or the scheduling request) at the transmission occasion of the first indication resource, or in the case that the first device sends the first information at the transmission occasion of the first indication resource and the first information is used to indicate that there is no CSI report at the fourth transmission occasion and / or there is no event, the fifth time duration is the first time duration. For example, the fifth time duration is one or more time domain units. For another example, the fifth time duration is 0 or Z3' symbols. This case corresponds to the dynamic mode 1 and the dynamic mode 2.

[0542] In the case that the first device sends the first information at the transmission occasion of the first indication resource and the first information is used to request the scheduling of the resource for sending the CSI report (i.e., Mode A), the fifth time duration is the interval between the last symbol of the second reporting resource and the last symbol of the first indication resource, plus the first time duration. Alternatively, the fifth time duration is the time interval between the occasion of sending the first information and the occasion of sending the CSI report. Alternatively, the fifth time duration is the time interval between the occasion of sending the first information and the scheduled second reporting resource. This case corresponds to the dynamic mode 4.

[0543] The dynamic manners 1, 2, 3, 3' and 4 described above are applicable to the case that the measurement resource is a periodic resource or a semi-persistent resource (a semi-persistent resource other than a DCI triggered periodic resource) associated with event triggered reporting. For the case that the measurement resource is a non-periodic resource or a semi-persistent resource (a semi-persistent resource in a DCI triggered periodic resource), the start point of the CPU occupation time of the dynamic manners 1, 2, 3, 3' and 4 is replaced by: the first time domain unit after the second indication resource. The following is a specific description

[0544] The embodiment of the present application further provides a method for determining CPU occupation time. The method comprises: a first device receiving configuration information, the configuration information being used for determining measurement resource corresponding to CSI reporting (or referred to as CSI reporting); and the first device determining CPU occupation time, the CPU occupation time being time occupied by the first device in processing the CSI reporting; wherein, a period of the first indication resource comprises a time interval between a first sending occasion and a second sending occasion, the first sending occasion and the second sending occasion being two adjacent sending occasions in the first indication resource, and the measurement resource being located in the period of the first indication resource in time domain.

[0545] Wherein, the first indication resource is used for sending first information, the third sending occasion is a sending occasion of the first information in the first indication resource, the first reporting resource is used for sending the CSI reporting, the fourth sending occasion is a sending occasion of the CSI reporting in the first reporting resource, and the first information is used for indicating that the fourth sending occasion associated with the third sending occasion exists the CSI reporting or whether the fourth sending occasion associated with the third sending occasion exists the CSI reporting.

[0546] Or, wherein the first indication resource is used for sending the first information, and the first information is used for requesting resource of the CSI reporting.

[0547] Wherein, the start point of the CPU occupation time can be the first time domain unit after the second indication resource, the second indication resource being resource for receiving third information, and the third information being used for triggering measurement of the measurement resource. (For example, the method comprises: the first device receiving third information in the second indication resource, the third information being used for triggering measurement of the measurement resource).

[0548] Wherein, in the case that the first device does not send the first information, the end point of the CPU occupation time can be the last symbol of the second sending occasion in the first indication resource plus a first time length.

[0549] Or, wherein the first device sends the first information, and the first information is used to indicate that the fourth sending occasion does not exist the CSI report, the end of the CPU occupation time can be the second sending occasion in the first indication resource, which is the last symbol of the third sending occasion, plus the first time length.

[0550] Or, wherein the first device sends the first information, and the first information is used to indicate that the fourth sending occasion exists the CSI report, the end of the CPU occupation time can be the last symbol of the fourth sending occasion in the first reporting resource, plus the first time length.

[0551] Or, wherein the first device sends the first information, and the first information is used to request to schedule resources for the CSI report, the end of the CPU occupation time is the last symbol of the second reporting resource (or called scheduled resource), plus the first time length, wherein the second reporting resource is the resource of the CSI report indicated by the second device. For example, the first device can receive the second information from the second device, and the second information is used to indicate the second reporting resource for sending the CSI report.

[0552] Other descriptions are similar and will not be repeated.

[0553] Based on the above scheme, the CPU occupation time can be determined according to whether the first information is sent and the content of the first information. The above scheme can flexibly determine the CPU occupation time, which helps the first device to more reasonably determine the CPU occupation time, thereby efficiently utilizing the CPU and reducing the conflict of CSI reporting.

[0554] For example, assuming that the second device (for example, a network device) configures the number of CPUs occupied by N CSI reports (including event triggered CSI reports) to be greater than the number of CPUs not occupied by the first device. Wherein the number of unoccupied CPUs can be represented as N CPU -L. Wherein, N CPU N can represent the number of CPUs supported by the first device (for example, a terminal device), and L can represent the number of occupied CPUs.

[0555] In the above case, the first device can not trigger (or does not need to trigger) the event triggered CSI report existing in N-M CSI reports with low priority, wherein, Wherein, This can represent the number of CPUs used by the nth CSI report. In some examples, the NM low-priority CSI reports may include conventional CSI reports, which the first device may not (or need not) update. For example, the aforementioned conventional CSI reports may include CSI reports triggered by the second device, CSI reports related to non-event-triggered reports, or CSI reports not initiated by the first device, etc.

[0556] In the above situation, the first device may not (or need not) monitor the measurements associated with the CSI reports triggered by the events present in NM low-priority CSI reports.

[0557] The following, combined with Figure 13 This application provides a detailed description of the communication device provided in the embodiments. The descriptions of the device embodiments correspond to the descriptions of the method embodiments; therefore, for content not described in detail, please refer to the above method embodiments. For the sake of brevity, some content will not be repeated.

[0558] This application embodiment can divide the communication device into functional modules according to the above method example. For example, each function can be divided into its own functional modules, or two or more functions can be integrated into one processing module. The integrated modules can be implemented in hardware, software, or a combination of both. The module division in this application embodiment is illustrative and only represents one logical functional division; other division methods may be used in actual implementation. The following description uses the division of functional modules according to each function as an example.

[0559] Figure 13 This is an exemplary block diagram of the communication device 10 provided in the embodiments of this application.

[0560] like Figure 13 As shown, for example, the communication device 10 may include a chip system 110, a memory 120, a bus 130, a power management module 140, or a transceiver 150, etc.

[0561] The chip system 110 can be an integrated circuit chip with signal processing capabilities. In implementation, each step of the above method can be completed through integrated logic circuits in the hardware of the chip system 110 or through software instructions.

[0562] By way of example and not limitation, the chip system 110 can include a circuit or chip responsible for processing of signals, such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or system in package (SIP) chip containing a modem core.

[0563] Optionally, the chip system 110 can also be provided with a memory (e.g., a cache) for storing instructions and data. In some embodiments, the memory in the chip system 110 is a cache memory. The memory can hold instructions or data that the chip system 110 has just used or recycled. If the chip system 110 needs to use the instructions or data again, it can be directly called from the memory. This avoids repeated access and reduces the waiting time of the chip system 110, thus improving the efficiency of the system.

[0564] In some embodiments, the chip system 110 can include one or more interfaces. The interfaces can include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface, etc.

[0565] The memory 120 can include a random access memory (RAM) and a read-only memory (ROM). The memory 120 can store computer-readable computer-executable code including instructions that, when executed, cause the processor to perform various functions described herein.

[0566] Optionally, the code can include instructions for implementing aspects of the present application, such as, for example, instructions for transmitting first information. The code can be stored in a non-transitory computer-readable medium such as system memory or other type of memory. In some cases, the code can not be directly executable by the processor 110 but can cause a computer (e.g., when compiled and executed) to perform functions described herein. In some cases, the memory 120 can include a basic I / O system that can control basic hardware or software operations such as interactions with peripheral components or devices.

[0567] By way of example, the chip system 110 performs various functional applications and data processing of the communication apparatus 10 by running instructions stored in the memory 120. For example, when the communication apparatus 10 performs file transmission with other devices (which can also be terminals or access network devices), the chip system 110 of the communication apparatus 10 can invoke computer executable program code stored in the memory 120 to implement the communication method provided by the embodiments of the present application.

[0568] In addition, the memory 120 can be integrated in the above-mentioned chip system 110 or independent of the chip system 110.

[0569] By way of example, the bus 130 can be a USB for supporting mutual communication between various parts in the communication apparatus 10.

[0570] The power management module 140 is configured to receive charging input from a charger. Optionally, the power management module 140 can supply power to the communication apparatus 10 (e.g., a battery module of the communication apparatus 10) while charging the communication apparatus 10. By way of example and not limitation, the power management module 140 can also supply power to devices other than the communication apparatus 10.

[0571] The transceiver 150 can communicate bi-directionally, via one or more antennas, wired, or wireless links as exemplified by the transceiver 150, which can represent a wireless transceiver and can communicate wirelessly with another wireless transceiver. The transceiver 150 can also include a modem to modulate the packets and to provide the modulated packets to the antennas for transmission, and to demodulate packets received from the antennas. In some cases, the transceiver 150 can include a plurality of transceivers. In some cases, the transceiver 150 can be collocated with a modem and / or a network interface within the communication apparatus 10. The modem can be used to modulate packets and to provide the modulated packets to the antennas for transmission, and to demodulate packets received from the antennas. Similarly, the network interface can be used to modulate packets and to provide the modulated packets to the network.

[0572] In some cases, the wireless device can include a single antenna. However, in some cases the device can have more than one antenna, like Figure 13The antennas 1 and 2 shown in FIG. 1 can be capable of transmitting or receiving multiple wireless transmissions simultaneously. Exemplarily, the antennas 1 and 2 are used for transmitting and receiving electromagnetic wave signals. Each of the antennas in the communication device 10 can be used to cover a single or multiple communication frequency bands. Different antennas can also be multiplexed to improve the utilization of the antennas. For example, the antenna 1 can be multiplexed as a diversity antenna for a wireless local area network. In some other embodiments, the antennas can be used in combination with a tuning switch. The communication device 10 can transmit files to other devices through a wireless communication function.

[0580] For example, display 162 is used to display images, videos, etc. The display includes a display panel. The display panel may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a mini light-emitting diode (LED), a microLED, a microOLED, a quantum dot light-emitting diode (QLED), etc. For example, in this embodiment, the display can be used to display the interface required by the communication device 10. For example, the communication device 10 implements display functions through a graphics processing unit (GPU), a display, and an application processor. The GPU is a microprocessor for image processing, connected to the display and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The chip system 110 may include one or more GPUs that execute program instructions to generate or modify display information.

[0581] For example, camera 163 is used to acquire images, videos, etc.

[0582] Understandable, Figure 13 The structure shown does not constitute a specific limitation on the communication device 10. The specific structure of the terminal equipment and / or access network equipment can be referred to Figure 13 As shown. In some embodiments, the communication device 10 may also include a... Figure 13 This could mean having more or fewer components, combining some components, separating some components, or having different component arrangements. Or, Figure 14 Some of the components shown can be implemented in hardware, software, or a combination of software and hardware. Terminal devices and / or access network devices can be implemented in… Figure 14 The components were added or removed based on the given structure.

[0583] Figure 14 This is a schematic block diagram of the communication device 20 provided in the embodiments of this application.

[0584] like Figure 8As shown, the communication apparatus 20 can include a baseband unit 210, which can communicate with an external device through a cellular radio frequency (RF) transceiver 220 (e.g., if the communication apparatus 20 is a terminal device, the baseband unit 210 can communicate with an access network device through the cellular RF transceiver 220; also e.g., if the communication apparatus 20 is an access network device, the baseband unit 210 can communicate with a terminal device and / or a core network device through the cellular RF transceiver 220).

[0585] The baseband unit 210 can include a computer-readable medium / memory. The baseband unit 210 can be responsible for general processing, including the execution of software stored on the computer-readable medium / memory. The software, when executed by the baseband unit 304, causes the baseband unit 210 to perform the various functions described supra.
