Beam: A beam is a communication resource. The beam can be a wide beam, or a narrow beam, or another type of beam. The beam forming technology may be a beam forming technology or other technical means. The beamforming technology may be specifically a digital beamforming technology, an analog beamforming technology, and a hybrid digital / analog beamforming technology. Different beams can be considered as different resources. The same information or different information can be transmitted through different beams. Optionally, multiple beams having the same or similar communication characteristics may be considered as one beam. A beam may include one or more antenna ports for transmitting data channels, control channels, and detection signals. For example, a transmission beam may refer to a signal intensity distribution in different directions of a space after a signal is transmitted by an antenna. The receiving beam may refer to a signal strength distribution of a wireless signal received from an antenna in different directions in space. It can be understood that one or more antenna ports forming a beam can also be regarded as an antenna port set. The embodiment of the beam in the protocol can still be a spatial filter.

Beam information can be identified by index information. Optionally, the index information may correspond to a resource identifier of a configured UE, for example, the index information may correspond to a configured ID or resource of a channel state information reference signal (CSI-RS), or may correspond to The ID or resource of the configured sounding reference signal (SRS). Alternatively, optionally, the index information may also be displayed or implicitly carried by a signal or channel carried by a beam. For example, the index information may be a synchronization signal sent by a beam or a broadcast channel indicating the beam. Index information.

Alternatively, optionally, the identification of the beam information includes the absolute index of the beam, the relative index of the beam, the logical index of the beam, the index of the antenna port corresponding to the beam, the index of the antenna port group corresponding to the beam, and the downlink synchronization signal block. Time index, beam pair connection (BPL) information, beam corresponding transmission parameters (Tx parameter), beam corresponding receiving parameters (Rx parameter), beam corresponding transmission weight (weight), weight matrix (weight vector) ), Weight vector (weight matrix), receiving weights corresponding to the beam, or their indexes, transmitting codebook corresponding to the beam, receiving codebook corresponding to the beam, or their indexes.

The above FIG. 1 shows a network system architecture involved in this application. This application is applicable to a beam-based multi-carrier communication system as shown in FIG. 1, such as a 5G new air interface NR. The system includes uplink (terminal device to network device) and downlink (access network device to terminal device) communication in the communication system. According to the long-term evolution LTE / NR protocol, at the physical layer, uplink communication includes the transmission of uplink physical channels and uplink signals. The uplink physical channel includes a random access channel (PRACH), an uplink control channel (PUCCH), an uplink data channel (physical uplink, shared channel, PUSCH), etc., and the uplink signal includes a channel detection signal SRS. An uplink control channel demodulation reference signal (PUCCH-demodulation reference signal, PUCCH-DMRS), an uplink data channel demodulation reference signal PUSCH-DMRS, an uplink phase noise tracking signal (PTRS), and the like. Downlink communication includes the transmission of downlink physical channels and downlink signals. The downlink physical channel includes a physical channel (PBCH), a downlink control channel (PDCCH), a downlink data channel (PDSCH), and the like. The downlink signal includes a primary synchronization signal (primary synchronization signal). (Referred to as PSS) / secondary synchronization signal (SSS), downlink control channel demodulation reference signal PDCCH-DMRS, downlink data channel demodulation reference signal PDSCH-DMRS, phase noise tracking signal PTRS, channel state information reference signal ( channel status information (CSI-RS), cell signal (CRS) (NR does not have), fine synchronization signal (time / frequency tracking reference signal (TRS) (not available in LTE)).

In NR, a beam indication of a beam used by a downlink channel or a beam corresponding to a reference signal transmission is implemented by using a reference resource index in an associated transmission configuration indicator (TCI) status table.

Specifically, the base station configures a TCI state table (corresponding to TCI-states in 38.331) through radio resource control (RRC) high-level signaling, and each TCI state table contains several TCI states (corresponding to TCI in 38.331). -RS-Set). Each TCI status includes TCI status ID (TCI-RS-SetID), one or two quasi-co-location (QCL) type indications (QCL-type A / B / C / D), and various type indications Corresponding reference RS-ID. QCL types include the following:

QCL-TypeA: {Doppler shift, Doppler spread, average delay, delay spread}

QCL-TypeB: {Doppler shift, Doppler extension}

QCL-Type C: {average delay, Doppler frequency shift}

QCL-Type D: {space receiving parameters}

Among them, QCL-type D represents spatial quasi-parity. When the receiving beam needs to be instructed, the base station indicates one of the TCI states containing spatial quasi-parity information through high-level signaling or control information. The UE reads the reference RS-ID corresponding to the QCL-type ID according to the TCI state, and the UE can then The currently maintained spatial receiving configuration (receiving beam) corresponding to the RS-ID is used for receiving. According to 38.214, if a TCI state contains a spatial quasi-parity indicator (QCL-typeD), the corresponding reference RS of the spatial quasi-parity indicator may be an SS / PBCH block or a periodic or semi-persistent CSI-RS. The beam indication (TCI indication) of different downlink channels is completed at different positions:

The beam of the PDCCH indicates that the high-level signaling tci-States PDCCH configured by the RRC is associated with one or more TCI states. When the number of associated TCI states is greater than one, the MAC-CE high-level signaling selects one of them.

The beam indication of the PDSCH is indicated by the state associated with the TCI field in the DCI transmitted by the PDCCH. The length of the TCI field included in the DCI in the NR standard is 3 bits (corresponding to 8 TCI states). When the number of TCI states M included in the RRC signaling is less than 8, the activated TCI state is directly mapped into the TCI field, otherwise the higher-level The order indicates a maximum of 8 TCI states participating in the mapping. When the high-level signaling prompts that the TCI field does not appear in the DCI, the UE reuses the beam indication of the control channel for data channel reception.

For uplink transmission, the NR has not yet defined a spatial quasi-parity relationship, and the uplink beam indication is directly implemented through the reference signal resource identifier:

The PUCCH beam indication is indicated by the RRC parameter PUCCH-Spatial-relation-info. This parameter may include one or more reference signal resource identifiers. When multiple reference signal resource identifiers are included, one of them is selected by MAC-CE higher-layer signaling. . The PUCCH beam indication content may be the uplink or downlink reference signal resource identifier, including SSB index, CRI, or SRS index, indicating that the UE is recommended to use the corresponding beam for receiving / sending the downlink / uplink reference signal resource for uplink transmission.

The beam information of the PUSCH is configured by the SRS index in the DCI. Quasi-co-location (QCL): A parity relationship is used to indicate that multiple resources have one or more of the same or similar communication characteristics. For multiple resources with a parity relationship, the same or similar Communication configuration. For example, if the two antenna ports have a co-located relationship, the large-scale characteristics of a channel transmitting one symbol at one port can be inferred from the large-scale characteristics of a channel transmitting one symbol at the other port. Large-scale characteristics can include: delay spread, average delay, Doppler spread, Doppler frequency shift, average gain, reception parameters, terminal device receive beam number, transmit / receive channel correlation, reception angle of arrival, receiver antenna Spatial correlation, angel-of-arrival (AoA), average angle of arrival, expansion of AoA, etc. Specifically, the parity indication is used to indicate whether the at least two sets of antenna ports have a parity relationship: the parity indication is used to indicate whether the channel state information reference signals sent by the at least two sets of antenna ports are from the same transmission point Or, the parity indication is used to indicate whether the channel state information reference signals sent by the at least two sets of antenna ports are from the same beam group.

Spatial QCL: Spatial QCL can be considered as a type of QCL. There are two angles to understand for spatial: from the sending end or from the receiving end. From the perspective of the transmitting end, if the two antenna ports are quasi co-located in the airspace, it means that the corresponding beam directions of the two antenna ports are spatially consistent. From the perspective of the receiving end, if the two antenna ports are quasi co-located in the airspace, it means that the receiving end can receive the signals sent by the two antenna ports in the same beam direction.

Channel measurement reference signal resource (reference signal resource for channel measurement): The reference signal resource sent on the beam to be measured. The channel measurement reference signal resource is only a reference signal resource for measuring the service beam quality. Note that the channel measurement reference signal resource is not necessarily limited to the channel state information measurement resource, and may also be a reference signal resource used for beam management. By definition, the channel measurement reference signal resource is regarded as a useful signal (the signal component included in the signal-to-noise ratio), and is used to measure the beam quality of the beam that transmits the channel measurement reference signal resource. The measurement results (RSRQ / SINR / RSRP) in the embodiments of the present application are all measurement results for the channel measurement reference signal resources. The channel measurement reference signal resources are processed as useful signals during the measurement. At the same time, when measuring the interference situation of the channel measurement reference signal resource (beam on which it is located), the beam of the channel measurement reference signal resource should be used to receive the interference signal (including the interference reference signal resource and other non-specific interference and noise). In the channel / beam quality measurement process for the measurement reference signal resource, the terminal device should assume that the interference reference signal resource and the channel measurement reference signal resource are spatially quasi co-located.

Interference reference signal resources: The interference reference signal resources are the reference signal resources sent on the interference beam. The terminal equipment should use these interference signal resources to measure the interference of the interference beam to the service beam. Note that the interference reference resource is not necessarily limited to the non-zero power interference measurement resource configured by the base station for channel state information measurement. It may also be a base station configured to the user terminal device as a potential service beam but not selected by the terminal device as a service beam. The reference signal resource corresponding to the beam, for example, a reference signal resource set used for beam management. Alternatively, when the terminal device selects and reports multiple beams or beam sets, the reported beams can also be used as mutual interference reference resources. By definition, the interference reference signal resource is used to measure interference power and corresponds to the interference power portion of the signal-to-interference-to-noise ratio. The interference reference signal resource itself may have a spatial quasi-parity assumption (the TCI state is configured, and its receiving beam indication depends on the associated TCI state), but when performing interference measurement as an interference resource, the terminal device should assume the interference reference signal resource and channel The measurement reference signal resources are spatially quasi-parity. The terminal equipment should use the receive beam of the channel measurement reference signal resource to receive the interference reference signal resource. The interference reference signal resource may be a non-zero power reference signal resource or a zero power reference signal resource. For a zero-power reference signal resource, its own reference signal resource has no power, but the interference of resources such as symbol / resource block (RB) / resource element (RE) can still be included in related measurements. Calculation.

Measurement resource set: The measurement resource set may refer to an interference measurement resource set and / or a channel measurement resource set. The measurement resource set is a resource set composed of time-frequency resources and / or reference signals participating in the measurement. According to different configurations of the channel reference signal resources and the interference reference signal resources, in different implementations, the measurement resources may have different determination schemes. This embodiment discusses more about the determination of interference measurement resources. For example, the interference measurement resource may be an RB (existing protocol) where the channel reference signal resource is located, an RE (existing protocol SINR) where it is located, or an interference measurement reference signal resource.

Measurement reference signal resource set: a set of measurement resources selected by a network device configuration or a terminal device according to a network configuration. The measurement reference signal resource set is a complete set of channel measurement reference signal resources and / or interference reference signal resources considered in the embodiments of the present application. The network device may be configured with a reference signal resource set dedicated to interference measurement or channel measurement, or may be configured with a single set as one of the embodiments in the embodiments of the present application, and the terminal device selects one of them as the channel measurement reference signal resource, and the other As an interference reference signal resource. The terminal device may also determine the measurement resource set according to the network configuration. For example, the terminal device is configured with a measurement reference signal resource set to allow the terminal device to select N from the set for reporting. At this time, the terminal device may use the selected N reference signal resources as the measurement reference signal resource set to perform related measurements.

In the embodiment of the present application, the channel measurement reference signal resource and the interference measurement reference signal resource may be converted into each other. For example, when a terminal device measures a reference signal resource set, if one of the reference signal resources is selected as a channel measurement reference signal resource, the remaining reference signal resources may be used as interference reference signal resources. In the same way, the channel measurement reference signal resource set and the interference measurement reference signal resource set can also be converted into each other. For example, when a terminal device measures multiple reference signal resource sets, if one of the reference signal resource sets is selected as a channel measurement reference signal resource, the remaining reference signal resource sets may be used as interference reference signal resources.

In the embodiments of the present application, the channel measurement reference signal resource and the interference measurement reference signal resource may be collectively referred to as a measurement reference signal resource.

It should be understood that, for the terms involved in the embodiments, reference may be made to the foregoing description. For brevity, details are not described herein.

Optionally, the interference measurement resource may be determined according to a channel measurement reference signal resource and multiple interference reference signal resources, where the multiple interference reference signal resources belong to an interference reference signal resource set.

It can be understood that the measurement quantity reported by the terminal device to the network device may be configured in advance by the network device to the terminal device through the measurement and reporting configuration information.

Specifically, the terminal device performs quantization processing on the measurement result to obtain a measurement result after the quantization processing; and the terminal device sends the measurement result after the quantization processing to a network device.

In the embodiment of the present application, when measuring a channel measurement reference signal resource, the terminal device needs to consider one or more interference reference signal resources and / or the influence of the channel measurement reference signal resource on the channel measurement reference signal resource to obtain a channel measurement. Measurement results of reference signal resources. The influence of the interference reference signal resource on the channel measurement reference signal resource may be interference caused by the reference signal power of the interference reference signal resource itself, or it may be the influence of the interference reference signal resource on the interference measurement resource.

Optionally, the measurement result of the channel measurement reference signal resource may be RSRQ. The RSRQ of the channel measurement reference signal resource can be defined as the ratio of the channel measurement reference signal resource to be measured to the interference power within the measurement range (that is, on the interference measurement resource), which can be specifically defined according to the following formula:

RSRQ = N * RSRP / RSSI

Among them, N is the number of measurement resource blocks RB of the RSSI; RSRP is the power measured on the resource element RE carrying the channel measurement reference signal resource (optionally, the measurement reference signal may be a CSI-RS or a secondary synchronization signal SSS) (Unit is Watt, W) Linear average value; RSSI is the total received power on the RB used to measure RSSI (including co-channel service) in the OFDM symbol that includes the channel measurement reference signal resource during the measurement bandwidth and measurement time Cell and non-serving cell interference, adjacent channel interference, thermal noise, etc.). It should be understood that the definition of RSSI is only exemplary and does not limit the embodiments of the present application. Meanwhile, in the embodiment of the present application, a resource range (ie, interference measurement resource) included in RSSI measurement may not be limited to the RB where the channel measurement reference signal resource is located. For example, in some embodiments, it may be the RB where all the reference signals in the measurement reference signal set (that is, the set of channel measurement reference signal resources and interference reference signal resources) are located. Similar concepts can also be extended to symbols, RE, etc. For granularity.

In the embodiment of the present application, the terminal device measures interference received by the receiving beam on an interference measurement resource, and may include three implementation manners, which will be described in detail below.

Optionally, as a first implementation manner, S210 includes:

The terminal device measures the interference measurement resource using a receiving beam corresponding to the channel measurement reference signal resource, and the interference measurement resource is determined according to the channel measurement reference signal resource and a plurality of interference reference signal resource sets. , Wherein the plurality of interference reference signal resources belong to an interference reference signal resource set.

Specifically, if there are multiple channel measurement reference signal resources, when calculating the RSRQ of each channel measurement reference signal resource, the terminal device should deal with all measurement reference signal resources (including the channel measurement reference signal resource and Interference reference signal resources) to measure the interference on the RB.

In a first implementation manner, a channel measurement reference signal resource and multiple interference reference signal resources belong to a same measurement reference signal resource set, and the interference measurement resource is the measurement reference signal resource set as an example. The channel measurement reference signal resource belongs to a measurement reference signal resource set, and can be considered as any measurement reference signal resource in the measurement reference signal resource set. For example, when measuring the RSRQ of the channel measurement reference signal resource, the terminal device should measure the interference on the RB where all the measurement reference signal resources in the measurement reference signal resource set where the channel measurement reference signal resource is located. In addition, the signal power of the reference signal resource itself other than the measurement reference signal resource of the channel to be measured in the measurement reference signal resource set may be included in the interference or may not be included in the interference, which is not limited. For example, when a network device configures a beam measurement set [CSI-RS # a, CSI-RS # b, CSI-RS # c] for a terminal device, when the terminal device calculates the RSRQ of CSI-RS # a, it should respond to the All reference signal resources [CSI-RS # a, CSI-RS # b, CSI-RS # c] measure interference (calculate RSSI) on the RB where CSI-RS # b and CSI-RS # c are signals Whether power is included in the interference corresponds to two different implementations. Specifically, the signal power of the CSI-RS # b itself may be included in the interference or may not be included in the interference; the signal power of the CSI-RS # c itself may be included in the interference or not included in the interference.

Optionally, as a second implementation manner, S210 includes:

Specifically, when calculating the RSRQ of a channel measurement reference signal resource in the measurement reference signal resource set, the terminal device should calculate the interference caused by other measurement reference signal resources in the measurement reference signal resource set to the channel measurement reference signal resource. .

In a second implementation manner, the channel measurement reference signal resource and the interference reference signal resource belong to the same measurement reference signal resource set, and the interference measurement resource is the measurement reference signal resource set as an example. For example, when a network device configures a measurement reference signal resource set [CSI-RS # a, CSI-RS # b, CSI-RS # c] for a terminal device, the terminal device should calculate the SINR of CSI-RS # a separately. Consider the interference caused by CSI-RS # b and CSI-RS # c in the set to CSI-RS # a. One method is to use the CSI-RS # a as a signal and the noise and interference of the RE where the CSI-RS # b or CSI-RS # c is located as noise interference terms (which can be averaged according to the number of REs) to calculate the SINR. Optionally, the signal power of the CSI-RS # b or CSI-RS # c itself may be included in the interference or may not be included in the interference (or a zero-power interference resource is configured).

In the embodiment of the present application, the interference measurement may also measure only the power of the interference reference signal resource itself, rather than the total power of the RB / RE where the interference reference signal resource is located. For example, when CSI-RS # b is used as interference, the interference power in the above first implementation and the second implementation may only count the signal power of CSI-RS # b (for example, RSRP of CSI-RS # b) , Not the total power of the RB / RE where CSI-RS # b is located.

Optionally, as a third implementation manner, S210 includes:

Specifically, when the terminal device measures a certain channel measurement reference signal resource in the measurement reference signal resource set, it should exclude the mutual influence of other measurement reference signal resources in the set.

In a third implementation manner, the interference measurement resource is determined by the channel measurement reference signal resource. For example, when a network device configures a beam measurement set [CSI-RS # a, CSI-RS # b, CSI-RS # c] for a terminal device, when the terminal device calculates the RSRQ of CSI-RS # a, The CSI-RS # b and CSI-RS # c resources interfered with CSI-RS # a in the receiving beam in the range. The power of the reference signal resource CSI-RS # b or CSI-RS # c should not be counted in. Interference from CSI-RS # a.

It should be understood that the foregoing embodiment is described by using the RB where the measurement resource is located as an example, and the same method may be extended to the RE, symbol, and subband where the measurement resource is located, which is not limited.

Optionally, the network device may use a high-level signaling (e.g., medium access control elements (MAC, CE), radio resource control (radio resource control, RRC)) or physical layer signaling downlink control information. A command (downlink control information) instructs the terminal device to select one or more of the above calculation methods.

Optionally, the channel measurement reference signal resource may be one or more resources.

Optionally, in the embodiment of the present application, the channel measurement reference signal resource and the interference reference signal resource may belong to the same resource set. Optionally, the channel measurement reference signal resource and the interference reference signal resource may belong to different resource sets, and the channel measurement reference signal resource and the interference reference signal resource may form multiple sets.

The above three implementation manners can be applied to the case of multiple reference signal resource sets. The following describes the specific implementation of the foregoing three implementation manners by taking the channel measurement reference signal resource and the interference reference signal resource as different measurement reference signal resource sets as an example.

For the first implementation manner described above, when calculating the RSRQ of the channel measurement reference signal resource, the terminal device should deal with the measurement reference signal resource set where the channel measurement reference signal resource is located and the measurement reference signal resource set where the interference reference signal resource is located. The interference on the RB where all the reference signal resources in the two measurement reference signal resource sets are measured is measured.

For the second implementation manner described above, when calculating the RSRQ of the channel measurement reference signal resource, the terminal device should separately calculate: each interference reference signal in the interference reference signal resource set versus each channel measurement reference signal resource in the channel measurement reference signal resource set. The interference caused, that is, one-to-one measurement of interference reference signal resources and channel reference signal resources.

For the third implementation manner described above, when the terminal device measures the reference signal resource on the measurement channel, the mutual influence of other interference reference signal resources in the measurement reference signal resource set where the interference reference signal resource is located should be excluded.

It should be noted that if the channel measurement reference signal resource and the interference reference signal resource belong to different sets of measurement reference signal resources, the network device can configure multiple measurement reference signal resources but does not clearly indicate which one is the channel measurement reference signal resource and which one The set serves as an interference reference signal resource. When a terminal device uses a certain set as a channel to measure reference signal resources, it needs to use the reference signal resources in the remaining set as interference. Optionally, the interference reference resource set may be a zero-power interference reference signal resource set, or may be a non-zero-power interference reference signal resource set. For a zero-power interference reference signal resource set, the signal power of the interference reference signal resource set itself can be considered to be constant zero. When measuring interference, the terminal device may be required to determine the beam to be used for measuring interference according to the current channel beam resource. For example, when measuring the interference of the interference resource CSI-RS # c to the channel resource CSI-RS # a, it should be assumed that the interference and channel resource CSI-RS # a are spatially QCL, and the terminal device should use the reception of CSI-RS # a The beam measures the interference of CSI-RS # c. Optionally, the embodiment of the present application may also define a panel when the terminal device measures the beam and interference. For example, a network device may configure a terminal device to select a beam on a panel (or report the beam and report the panel ID at the same time). Accordingly, the interference measured by the terminal device should be based on the antenna panel where the report beam is located (or the panel ID reported together with the report beam) Corresponding panel).

It should be noted that the measurement range of the interference measurement resource may be the RB where a single measurement resource is located, or the continuous bandwidth occupied by a single measurement resource (from the start RB of the measurement resource to the continuous bandwidth including all measurement resources), or, It may be the maximum RB or continuous bandwidth occupied by all single measurement reference signal resources in the measurement reference signal resource set, or it may be the RB or continuous bandwidth occupied by all measurement resources in the measurement resource set as a whole. Broadband width can be measured in RB, RE, or Hz.

Optionally, in the embodiment of the present application, the channel measurement reference signal resource and the interference reference signal resource may correspond one-to-one.

Optionally, if the interference reference signal resource belongs to the interference reference signal resource set, the terminal device may perform a one-to-one analysis on each interference reference signal resource in the interference reference signal resource set when measuring the interference received by the beam where the channel measurement reference signal resource is located Iterate. Alternatively, the terminal device may measure interference caused by the entire interference reference signal resource set to the beam on which the channel measurement reference signal resource is located.

It should be noted that the configuration of the measurement reference signal resource set is not limited in the embodiments of the present application. Optionally, the measurement reference signal resource set may be a set of reporting beams (reference signal resources) selected by the terminal device during beam reporting. Here, the terminal device should perform the above measurement in the reported reference signal resource. Specifically, for example, the measurement set configured by the network device to the terminal device is [CSI-RS # a, CSI-RS # b, CSI-RS # c], and the terminal device selects the reporting beam set as [CSI-RS # a, When CSI-RS # b], the terminal device should calculate the set [CSI-RS # a, CSI-RS # b] using one or more of the above three implementation methods. Optionally, the terminal device selects and reports multiple measurement reference signal resource sets (for example, packet beam reporting), and the above three implementation manners are also applicable to interference measurement between sets.

For a case in which a terminal device reports beams on multiple antenna panels at the same time, the above-mentioned three implementation manners are also applicable to reporting interference measurement between different panels within a beam range. For example, the terminal reported that CSI-RS # a and CSI-RS # b belong to Panel A, and CSI-RS # d and CSI-RS # c belong to Panel B (Note that this example focuses on CSI-RS # a to d belong to different panels and may not be displayed in different sets). At this time, if the antenna panels are grouped, the equivalent measurement resource sets can be [CSI-RS # a, CSI-RS # b] and [CSI-RS # c, CSI-RS # d] (Note: the associated antenna panel may not be displayed, only the beams in different packets can be constrained to be received at the same time, and only one beam can be received in the same packet at the same time.) At this time, the terminal device can follow Measurement is performed in one of the above three implementation manners. For example, consider the measurement of interference between groups, and measure the interference of [CSI-RS # a, CSI-RS # b] and [CSI-RS # c, CSI-RS # d] in a one-to-one traversal manner. In addition, the network device may also require the terminal device to report multiple beam packets, and the beams in different packets are restricted from being received at the same time, and the same packets may be received at the same time. At this time, the terminal device may perform measurement according to one of the foregoing three implementation manners. For example, consider the intra-group interference measurement, and measure the interference conditions in the two groups [CSI-RS # a, CSI-RS # b] and [CSI-RS # c, CSI-RS # d] according to the first calculation method.

Optionally, the terminal device performing quantization processing on the measurement result may include: the terminal device may perform non-uniform quantization on the measurement result obtained above. Wherein, the quantization information such as the quantization method and quantization parameter used by the terminal device may be agreed by the protocol, or may be configured by the network device to the terminal device, which is not limited in this embodiment of the present application.

For example, the network device may configure a terminal device with a quantization method of A-law or μ-law non-uniform quantization, and provide a corresponding quantization parameter A or μ. After the terminal device obtains the above quantization parameters, it can normalize the measurement result x (such as RSRQ), companding (can be understood as non-uniform scaling mapping) in the following corresponding manner to obtain F (X), and then F (X) ) Perform uniform quantization and report. The [quantized minimum value, quantized maximum value] in normalization can be agreed by the agreement, or can be configured for the terminal device through the network device. For example, the normalized quantization range can be [0,1], also Can be [-1,1]. For example, here F (X) is used to represent the unquantized measurement results, such as the measured RSRQ and SINR. If the quantization parameter A is used, F (X) can be calculated according to the following formula (1):

Alternatively, if the quantization parameter μ is used, F (X) can be calculated according to the following formula (2):

Optionally, the embodiment of the present application may also quantify the measurement result in a predefined quantization manner. The terminal device can obtain a quantized measurement result based on the mapping relationship between the measurement result and the reported bits. Optionally, the mapping relationship may be agreed through a protocol, or may be indicated by the network device to the terminal device through an RRC or MAC message. Optionally, the mapping between the measurement result and the quantized measurement result may have one or more intermediate quantities, or there may be no intermediate quantity (that is, the measurement result is directly mapped to the quantized measurement result). Table 1 shows the mapping relationship between the reported bit value and the intermediate quantity, and Table 2 shows the mapping relationship from the intermediate quantity to the quantized value range. The specific mapping relationship is shown in Table 1 and Table 2:

Table 1: Mapping from reported bit values to intermediate quantities

上报比特值Report bit value	中间量Intermediate amount
0..00..0	range(1)range (1)
0..10..1	range(2)range (2)

Table 2: Mapping relationship from intermediate quantities to quantized value ranges

range(2)range (2)	X2≤Quantity<X1X2≤Quantity <X1
…...	…...
range(N)range (N)	X _N≤Quantity X _N ≤Quantity

Specifically, after the measurement results obtained by the terminal device (corresponding to the measurement results such as RSRQ, SINR, etc.), take the measurement result as X1 as an example, and look up Table 2 through Table 2. 1) range, then look up Table 1, and get the reported bit corresponding to range (1) is 0..0, then the bit value reported by the terminal device to the network device is 0..0. It should be noted that the number of bits of reported bit values in Table 1 is not limited here, and can be determined flexibly according to requirements.

The mapping relationship in the above Table 1 and the mapping relationship in Table 2 are embodied by two tables, but they are not limited to the embodiments of the present application. Optionally, in a possible implementation manner, the foregoing Table 1 and Table 2 may also be combined into one table, which is not limited.

It should be understood that those skilled in the art may perform various transformations on the values or corresponding relationships in Table 1 or Table 2. The mapping relationship in Table 1 and Table 2 is used as an example for description, and the embodiments of the present application are not described. Composition limitation.

Optionally, the measurement result includes a second measurement amount, and the method 200 further includes:

Specifically, for the same channel measurement reference signal resource, the terminal device may receive a first measurement threshold of a first measurement amount of the channel measurement reference signal resource. Then, the terminal device measures the first measurement amount of the channel measurement reference signal resource. If the first measurement amount meets the first measurement threshold, the terminal device reports the second measurement amount of the channel measurement reference signal resource. The second measurement amount is a report amount that needs to be reported to the network device.

Optionally, the network device may configure the terminal device to measure the reference resource set and select N reference signal resources, and report the corresponding reference signal resource index (for CSI-RS resources, the index is CSI-RS index, CRI) And the reported amount of measurement (the reported amount of the second measurement amount). At the same time, the network device may specify a reporting threshold for the terminal device (such as the first measurement threshold for the first measurement quantity), and the first measurement quantity corresponding to the reported beam (reference signal resource) selected by the terminal device must satisfy the first measurement threshold.

For example, a network device may configure a reference signal resource set [CSI-RS # a, CSI-RS # b, CSI-RS # c], and notify the terminal device to select N beams to report its corresponding CSI-RS resource index (CSI -RS index, CRI) and RSRQ (reported quantity on the second measurement quantity). At the same time, the network device can configure (also can be agreed in the agreement) an RSRP threshold through additional RRC / MAC-CE. The first measurement quantity (RSRP in this example) corresponding to the reported CSI-RS resource index selected by the terminal device must satisfy the first measurement threshold (RSRP threshold in this example) in order to report the reported quantity (RSRQ in this example) . The RSRP that the terminal device chooses to report to the CRI must meet the RSRP threshold configured by the network device. When there is no CRI that meets the threshold configured by the network device, the terminal device may report to the network device through an abnormal value (such as an abnormal CRI or an abnormal second measurement value (RSRQ in this example) or other abnormal state).

In another form of this embodiment, when the terminal device calculates the RSRQ of the reference signal resource (for example, according to the formula RSRQ = N * RSRP / RSSI), it will report to the network device only when the RSRP of the reference signal resource meets the RSRP threshold. RSRQ.

Optionally, the network device may instruct the terminal device to measure and report multiple different measurement quantities for a group of measurement reference signal resources, and the multiple measurement quantities may correspond to a measurement result of the same CRI. For example, the network device may configure a channel measurement reference signal resource, and configure the terminal device to select N reference signal resources from it, and report the index of the N reference signal resources, the RSRP corresponding to each reference signal resource, and the RSRQ of each reference signal resource. .

Optionally, the network device may also indicate a priority between different reported quantities in a display, implicit, or protocol manner. The priority may refer to a priority for beam selection (that is, a beam is selected in consideration of the measurement quantity). It can also refer to the priority of measurement (that is, to measure the measurement priority). The display indication can be completed through RRC / MAC CE configuration, such as setting the priority order from high to low: RSRQ, SINR, RSRP; implicit indication can be completed by configuring the reporting amount, such as when the terminal device is required to report CRI-RSRQ -For RSRP, if RSRQ precedes RSRP, it means that the priority of RSRQ is higher than RSRP beam selection. Optionally, the order of priorities can also be understood as the conditional order of the measurement quantities, which is not limited.

If there are measurement results corresponding to multiple measurement reference signal resource sets that need to be reported, the terminal device needs to report the measurement reference signal resource sets corresponding to the measurement results. Specifically, for example, the network device configures two reference signal resource sets for the terminal device, and instructs the terminal device to perform measurement and report the measurement result. The terminal device can distinguish the measurement results of different reference signal resource sets through CRIs with different bit lengths, or, Additional bits may be used to indicate the reference signal resource set information. It should be understood that the manner in which the terminal device indicates to the network device different measurement results of the reference signal resource set is not specifically limited herein.

In the embodiment of the present application, the interference measurement resource may be divided into multiple resource groups, and the terminal device may perform interference measurement on each measurement group. The resource grouping of the interference measurement resources and related configuration information of each resource grouping may be agreed by the protocol, or may be configured by the network device for the terminal device, which is not limited. The following describes the configuration of network equipment for terminal equipment.

Optionally, the network device may divide the resource grouping of the interference measurement resources in the following manner, for example: frequency resource grouping based on interference measurement resources, a time domain measurement resource subset of the interference measurement resources, or a resource domain of the interference measurement resources Subset. In other words, the following resource grouping indication method can be applied only to the interference reference signal resource set, the channel measurement reference signal resource set, and the channel measurement reference signal resource set and the interference reference signal resource set. This is not limited.

Optionally, the network device may configure a frequency measurement range of the measurement resource and / or a frequency resource group corresponding to the measurement resource for the terminal device. For example, when the network device instructs the terminal device to perform measurement on the RSRQ of the CSI-RS # a, it may also indicate a measurement resource range for measuring the RSRQ, that is, group the measurement resource set. Optionally, the measurement resource set grouping may be applied only to the measurement of RSSI, or may be applied only to the measurement of RSRP, and may also be applied to the measurement of both RSSI and RSSP.

Optionally, the grouping of the interference measurement resource by the network device may be a grouping of a frequency domain resource and / or a time domain of the interference measurement resource. Taking the indication of frequency domain measurement resource grouping as an example, the complete set of frequency domain measurement resources (or the complete set of frequency domain interference measurement resources) can be defined as the RB where the single reference signal resource to be measured is located, or it can be the single reference signal resource to be measured. Occupied continuous bandwidth (from the starting RB of measurement resources to the continuous bandwidth containing all measurement resources), or it can be (channel and / or interference) the RB or continuous bandwidth occupied by all individual measurement resources in the measurement reference signal resource set The maximum value may alternatively be the RB or continuous bandwidth occupied by all measurement resources in the (channel and / or interference) measurement reference signal resource set. Broadband width can be measured in RB, RE, or Hz. The frequency domain measurement resource grouping is used to further divide and indicate the complete set of frequency domain measurement resources.

Optionally, the network device may use any of the following indication modes to instruct the complete set of frequency domain interference measurement resources:

Method 1: The network device uses a bitmap or a digitmap to divide the complete set of frequency-domain interference measurement resources into Nb groups. The following takes Nb = 3 as an example. As shown in Table 3, with the starting resource as 0, the complete set of frequency domain measurement resources is divided into {0,1,3,6}, {2,7}, {4,5 } Three subsets. It should be understood that a bitmap or a digit map is used as an example for description here. Network devices may use other forms for grouping, which is not specifically limited.

table 3

频域测量资源Frequency domain measurement resources	a1a1	a1a1	a2a2	a1a1	a3a3	a3a3	a1a1	a2a2

Method 2: The network device divides the complete set of frequency domain measurement resources into Nb subsets by indicating the location of Nb-1 RBs (it should be understood that RBs can also be extended to other resources such as RE / subband), and the resources of each subset are indicated by The RB position is used as the starting point. For example, Nb-1 = 2 positions indicated by the network device is 3,5 (RB). When the complete set of measurement resources in the frequency domain is 8RB, the complete set of frequency resources is divided into {0 ～ 3}, {4 ～ 5}, { 6 to 7} three sets, similar implementations may also be three sets of {0 to 2}, {3 to 4}, and {5 to 7}, which are not limited.

Method 3: The network device divides the full set of frequency domain measurement resources into Nb groups of equal size measurement resource subsets with a fixed bandwidth (the first two groups may not be the same size). The bandwidth of each group can be configured by the network device (such as RRC), or it can be agreed by the protocol, or calculated based on the total bandwidth (see the calculation method in the prior art), such as the subband size and the total bandwidth RB number. Correlation (may require additional RRC instructions to determine), as the total bandwidth RB number is in a different range, its own size also changes accordingly.

Optionally, the network device may configure a time domain measurement resource subset of the measurement resource set for the terminal device, that is, the network device may indicate grouping information of the time domain measurement resource subset.

Taking Figure 3 as an example, for the measurement resource CSI-RS # a, taking bitmap [0,1,1] as an example, the network device divides its periodic time domain resources into two groups, the {0,3,6 …} The timing (occasion) of one CSI-RS # a is a group, that is, measurement resource group 1 shown in FIG. 3, and the timing (occasion) of the {1,2,4,5 ...} th CSI-RS # a ) Is a group, that is, measurement resource group 2 shown in FIG. 3. Occasion of CSI-RS # a is the number of cycles (which can start from 0) of the CSI-RS resource after a certain starting position (which can have an offset). For periodic CSI-RS resources, the starting position may be the position with a frame number of 0; for semi-persistent CSI-RS resources, the starting position may be the position where the MAC-CE is activated, or the terminal device may activate the semi-persistent CSI-RS. The MAC-CE message of the resource feeds back the time slot of the ACK / NACK and so on. It should be understood that FIG. 3 is only exemplarily described with measurement resource group 1 and measurement resource group 2, and only shows a part of the composition of the measurement resource group, and does not limit the embodiment of the present application.

It should be understood that the number of bits of the bitmap is not limited in the embodiment of the present application, for example, the bitmap may also be 4 bits.

For example, for the measurement resource CSI-RS # a, taking bitmap [0,0,1,1] as an example, the network device divides its periodic time domain resources into two groups, the {0,4,8 …} And {1,5,9…} CSI-RS # a's timing (occasion) as a group, the {2,6,10…} and {3,7,11…} CSI-RS # a Occasion as a group.

Optionally, the network device may configure a resource domain measurement resource subset of the measurement resource set for the terminal device, that is, the network device may indicate grouping information of the resource domain measurement resource subset.

For example, the corresponding measurement resource set [CSI-RS # a, CSI-RS # b, CSI-RS # c, CSI-RS # d], taking bitmap [0,0,1,1] as an example, at this time [CSI-RS # a, CSI-RS # b] is a resource subset, and [CSI-RS # c, CSI-RS # d] is a resource subset.

It should be understood that the frequency measurement range, time domain measurement resource subset, and resource domain measurement resource subset configured by the network device for the terminal device may be used in combination with each other, which is not limited in the embodiment of the present application.

Optionally, in the above embodiments involving interference measurement resource grouping, if the network device configures the reporting threshold for the measurement result for the terminal device, the same reporting amount can be configured for each interference measurement resource group, and the terminal device needs to Measure in the measurement resource group and select report. The network device can also configure different reporting amounts for each interference measurement resource group, and the terminal device also needs to perform measurement and select reporting in each interference measurement resource group. Optionally, the network device may also configure different reporting priorities, thresholds, and quantization tables for each group of interference measurement resources, which is not limited.

Optionally, the network device may instruct or agree to report only measurement results of a certain group or groups of measurement packets (for example, resources corresponding to 'bit 1'). In this way, the terminal device can report according to the instructions of the network device or the protocol agreement, without the need to report the measurement results of each group of resource groups.

Optionally, the terminal device may also actively select one or more groups to report measurement results from the multiple groups of interference measurement resource groups, and notify the network device of the group index of its own choice (for example, the group index field is additionally defined in the UCI reporting format).

It should be understood that the embodiment of the interference measurement resource grouping in the embodiment of the present application may be implemented alone or in combination with the foregoing embodiments, which is not specifically limited in this application.

It should also be understood that the example in FIG. 3 is only to facilitate those skilled in the art to understand the embodiments of the present application, and it is not intended to limit the embodiments of the present application to specific illustrated scenarios. Those skilled in the art can obviously make various equivalent modifications or changes according to the example of FIG. 3, and such modifications or changes also fall within the scope of the embodiments of the present application.

It should also be understood that the various solutions of the embodiments of the present application can be used in a reasonable combination, and the explanations or descriptions of the terms appearing in the embodiments can be referred to or explained with each other in the embodiments, which is not limited.

It should also be understood that, in various embodiments of the present application, the size of the sequence numbers of the above processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not be implemented in this application.
