Description

Information configuration method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information configuration method and apparatus.

Background

In the discussion of NR (New Radio, new air interface), high frequency communication needs to be supported, and one of the significant features of high frequency communication is the need for beam-based transmission. Currently, a CSI-RS (Channel State Information Reference Signal) can be used for acquiring CSI (Channel State Information) similar to a low frequency, and can also be used for beam management; when CSI-RS is used for beam management, especially for high frequency hybrid beam management, a significant difference from low frequency beam training is that multiple beams corresponding to one radio link need to be transmitted in time division, while low frequency digital beams can generate many beams at one time. Therefore, how to design the CSI-RS pattern so that it can support both low frequency beam training and CSI acquisition and high frequency beam training and CSI-RS acquisition is a problem to be solved. In addition, at present, the CSI-RS of a partial bandwidth is also supported, so the influence of this function on the CSI-RS pattern design needs to be considered.

the number of repeated transmissions of the sounding reference signal in one period;

and measuring the toilet dressing grade corresponding to the reference signal.

In an exemplary embodiment, the activation and deactivation states are represented by the same indicator value, the first transmission of the indicator value represents activation, and the second transmission of the indicator value represents deactivation;

and/or, the indication value changes to indicate that a new resource is activated and an old resource is deactivated.

It should be noted that the method of this embodiment may also be used for other resources, such as measurement reference reporting resources and measurement reference signal measurement resources.

In an exemplary embodiment, the multiple types of time domain parameters include a first type of time domain parameters and a second type of time domain parameters, where the first type of time domain parameters indicate periodic characteristics of the sounding reference signal resources, and the periodic characteristics include: periodic, half-periodic, non-periodic; the second type of time domain parameter indicates that a time domain symbol set included in the sounding reference signal or the sounding reference resource is divided into a plurality of time domain regions, and at least one of a first transmission parameter and a first reception parameter of the sounding reference signal or the sounding reference signal resource corresponding to different time domain regions is different from the other.

the receiving parameters include: receiving a beam;

In an exemplary embodiment, the configuration information may be carried by at least two pieces of control information.

The embodiments of the present application are described below by way of examples.

Example one

This embodiment illustrates a sharing method for sharing transmission parameters by multiple CSI-RS resources.

Referring to the CSI-RS structure of the current NR, as shown in fig. 2, one reference signal set (RS setting) includes S CSI-RS resource sets (resource sets) (corresponding to the above measurement reference signal resource sets), and each CSI-RS resource set includes Ks CSI-RS resources (resources). Wherein S and Ks are both positive integers. Fig. 5 shows that different sets of srs resources correspond to different transmission beams.

The first implementation manner of sharing the transmission parameters by multiple CSI-RS resources is that the transmission parameters are configured in the configuration information of the RS setting, and all CSI-RS resources included in the RS setting share the transmission parameters, so that there may be no configuration of the transmission parameters in the configuration information of the CSI-RS resources; for example, the transmission parameter may be a frequency domain Resource, the number of bits required for the frequency domain Resource is 10 bits, if 8 CSI-RS resources share the transmission parameter, the frequency domain Resource only needs to be configured once in the configuration information of the RS setting, that is, only 10 bits are required, and if a sharing manner is not adopted, 10 × 8 bits are required to configure the frequency domain Resource in the configuration information of each CSI-RS Resource.

As shown in fig. 3, multiple CSI-RS resources share a frequency domain resource, in fig. 3, different CSI-RS resources are time-divided; however, the present embodiment does not exclude that some or all of the time domains of the CSI-RS resources overlap. The frequency domain Resource occupied by the CSI-RS is a frequency domain PRB (Physical Resource Block) set occupied by the CSI-RS on a time domain symbol occupied by the CSI-RS, and at this time, the frequency domain Resource included in the frequency domain PRB set is continuous, or the frequency domain Resource included in the frequency domain PRB set may also be discontinuous. Or, at this time, the indication information of the frequency domain resources indicates whether the frequency domain resources are wideband or partial bandwidth, and the frequency domain resources corresponding to the wideband and the partial bandwidth are predetermined. The CSI-RS resource may occupy all subcarriers in the frequency domain resource or only occupy part of the subcarriers.

For the beneficial effect brought by sending other transmission parameters based on the sharing mode, the beneficial effect brought by the frequency domain resource based on the sharing mode can be referred, and therefore details are not repeated here.

In a second implementation manner of sharing the transmission parameters by multiple CSI-RS resources, the transmission parameters are configured in the configuration information of the CSI-RS resource set, and all CSI-RS resources included in the CSI-RS resource set share the transmission parameters.

In a third embodiment of the multiple CSI-RS resource sharing transmission parameters, the transmission parameters are included in configuration information of each of the M CSI-RS resources, and it is agreed that the transmission parameters corresponding to the M CSI-RS resources are the same; wherein M is an integer greater than 1.

In a fourth embodiment of sharing transmission parameters by multiple CSI-RS resources, the transmission parameters are determined according to the type of sounding reference signal resource; for example, when the sounding reference signal belongs to type 1 (for example, type 1 is a sounding reference signal for beam management), its transmission parameter is a first predetermined value (for example, when the frequency domain occupied by the sounding reference signal is a partial bandwidth), and when it belongs to type 2 (for example, for the sounding reference signal for obtaining information such as PMI (Precoding Matrix Indicator), RI (rank indication), etc.), its transmission parameter is a second predetermined value.

In a fifth embodiment of sharing transmission parameters by multiple CSI-RS resources, the transmission parameters are determined according to feedback resources corresponding to measurement reference signal resources; for example, when the feedback modes are different, or PUCCH (Physical Uplink Control Channel)/PUSCH (Physical Uplink Shared Channel) resources occupied by the feedback information are different, the transmission parameters are different.

A sixth implementation manner of sharing the transmission parameter by the multiple CSI-RS resources is to indicate in RS setting whether the CSI-RS resources in the CSI-RS resource set need to share the transmission parameter. When the transmission parameters are shared, the relevant transmission parameters are set in the CSI-RS resource set, and when the transmission parameters are not shared, the transmission parameters are set in each CSI-RS resource. Or, related transmission parameters are set in both the CSI-RS resource and the CSI-RS resource set, priorities of the CSI-RS resource and the CSI-RS resource set are configured in RS setting, when the priority of the CSI-RS resource is set to be higher than the priority of the CSI-RS resource set, the transmission parameter of one CSI-RS resource is based on the transmission parameter configured in the CSI-RS resource, otherwise the transmission parameter of one CSI-RS resource is based on the transmission parameter configured in the CSI-RS resource set.

The seventh implementation manner of the multiple CSI-RS resources sharing the transmission parameter is to set whether the multiple CSI-RS resources included in the CSI-RS resource set share the transmission parameter in the CSI-RS resource set. The transmission parameters are configured in the CSI-RS resource set when the transmission parameters are shared, and configured in the CSI-RS resource when the transmission parameters are not shared. Or, related transmission parameters are set in both the CSI-RS resource and the CSI-RS resource set, the CSI-RS resource set is configured with priorities of the CSI-RS resource and the CSI-RS resource set, when the priority of the CSI-RS resource is set to be higher than the priority of the CSI-RS resource set, the transmission parameter of one CSI-RS resource is based on the transmission parameter configured in the CSI-RS resource, otherwise, the transmission parameter of one CSI-RS resource is based on the transmission parameter configured in the CSI-RS resource set.

An eighth way for sharing the transmission parameters by multiple CSI-RS resources is to establish one transmission parameter configuration information, where the configuration information may include index information of the transmission parameter configuration information in at least one of the following configuration information: CSI-RS resource configuration information, CSI-RS resource set configuration information and RS setting configuration information. As shown in fig. 4, a piece of transmission parameter configuration information is established, and index information (e.g., ID) of the transmission parameter configuration information is included in the configuration information of the CSI-RS resources.

Example two

The present embodiment illustrates transmission parameters shared by multiple CSI-RS resources.

The first sharing parameter is a time unit offset (also referred to as a time unit offset), for example, a periodic configuration parameter is shared by multiple CSI-RS resources occupying the same timeslot, where the timeslot parameters corresponding to the multiple CSI-RS resources are the same. The multiple CSI-RS resources can be transmitted periodically or transmitted in half period. For example, the transmission period of the CSI-RS resource is T, the time unit is offset to Δ T, and at this time, the set of slots occupied by the CSI-RS resource is { n, mod (n + Δ T, T) =0}, where n is an integer greater than or equal to 0, Δ T is an integer less than T, where n, Δ T, and T have the same unit, and are a time unit, such as a slot, or a time domain OFDM symbol, and the like. .

The second sharing parameter is a time domain symbol position, and the CSI-RS resources occupying the same time domain symbol are grouped into one group, as shown in fig. 6, both CSI-RS resource 0 and CSI-RS resource 1 are 2 nd time domain symbols occupying one slot (slot), and although the slots occupied by them are different, the time domain symbol positions occupied in the slot are the same. The shared parameter for CSI-RS resource 0 and CSI-RS resource 1 at this time is the time domain symbol position. In fig. 6, the CSI-RS resource 0 and the CSI-RS resource 1 occupy the same time domain symbol index, but occupy different time slots, however, this embodiment does not exclude the case where the CSI-RS resource 0 and the CSI-RS resource 1 occupy the same time domain symbol index and occupy the same time slot.

In another embodiment, as shown in fig. 7, the time domain symbol may include at least one of: a first subcarrier time domain symbol, a second subcarrier time domain symbol. For example, the subcarrier spacing of the CSI-RS may be allowed to increase, and the shared parameter may be the second subcarrier time domain symbol position. Wherein the time domain symbol position comprises at least one of: a first subcarrier time domain symbol position, a second subcarrier time domain symbol position. As shown in fig. 8, one slot includes 7 OFDM symbols at a first carrier spacing, CSI-RS resource 0 and CSI-RS resource 1 are located at different time-domain symbol index positions of the first subcarrier spacing, but the occupied time-domain symbols of the second subcarrier have the same phase index in a time-domain symbol of the second subcarrier, and CSI-RS resource 0 and CSI-RS resource 1 are both at the time-domain symbol index position of the second subcarrier spacing with the occupied index of 2. Wherein, one first carrier interval time domain symbol includes 4 second carrier time domain symbols, and the shared parameter is the second subcarrier time domain symbol index or the phase index of the second subcarrier time domain symbol in the first subcarrier time domain symbol.

The third sharing parameter is the number of time-domain repeated transmission times (or the density information of the measurement reference signal) in one period, and in the exemplary embodiment, at least one of the frequency-domain resource and the code-domain resource occupied by the CSI-RS resource in each time domain is the same when the time-domain repeated transmission is performed. As shown in fig. 9, CSI-RS resource 0 and CSI-RS resource 1 are repeatedly transmitted 3 times for the terminal to perform receive beam training. In fig. 9, the repeatedly transmitted time domain symbols in one CSI-RS resource are adjacent, however, this embodiment does not exclude the non-adjacent case. The repeated transmission may also be equivalent to the number of time domain symbols of the second carrier interval included in the time domain symbol of the first subcarrier interval, that is, there is a relationship between the repeated transmission and the number of time domain symbols of the second carrier interval included in the time domain symbol of the first subcarrier interval. As shown in fig. 9, assuming that 3 time domain carrier spacings are the second subcarrier spacings, and 1 first subcarrier spacing time domain symbol includes 3 second subcarrier spacing time domain symbols, when the number of repeated transmissions is set to 6, then the 1 first subcarrier spacing time domain symbol includes 6 second subcarrier spacing time domain symbols (at this time, the 6 corresponding second carrier spacings may be larger than the subcarrier spacing including 3).

The fourth sharing parameter is the number of time domain symbols occupied by one CSI-RS resource in one period, where the number of occupied time domain symbols may be at least one of: the number of time domain symbols of the first subcarrier in fig. 8, and the number of time domain symbols of the second subcarrier in fig. 8. The sharing parameter may also be the number of time domain symbols occupied by one CSI-RS port in one period.

The fifth sharing parameter is a pattern configuration parameter, and at least one of the following occupied by at least one of the srs resource and the srs can be obtained according to the pattern configuration parameter: time domain resources, frequency domain resources, code domain resources. As shown in fig. 10, the CSI-RS resource 0 and the CSI-RS resource 1 occupy the same time domain resource (where the same time domain resource means the same number of time domain symbols occupied), and at this time, at least one of the frequency domain resource and the code domain resource occupied by the CSI-RS resource 0 and the CSI-RS resource 1 are the same.

The sixth type of shared parameter is a second type of time domain parameter, where the second type of time domain parameter indicates that a first time domain symbol set corresponding to at least one of a sounding reference signal and a sounding reference signal resource is divided into N time domain regions (or may also be referred to as time regions, time domain symbol units, and the like), and at least one of a first transmission parameter and a first reception parameter corresponding to different time domain units is different. As shown in fig. 11, each period of the CSI-RS resource 0 and the CSI-RS resource 1 includes 6 time domain symbols, and then the 6 time domain symbols are divided into 3 time domain regions, where the division manners of the time domain regions of the two resources in fig. 11 are completely the same. However, this embodiment does not exclude that one aspect of the two time domain region divisions is the same, for example, the number of the divided time domain regions is the same, but the number of the time domain symbols included in each time domain unit is different. As shown in fig. 11 and 12, CSI-RS resource 0 (corresponding to fig. 10) is divided into 3 time domain regions, and CSI-RS resource 1 (corresponding to fig. 11) is divided into 3 time domain regions, but each of the time domain regions of CSI-RS resource 0 and CSI-RS resource 1 includes different numbers of time domain symbols. In fig. 11 and 12, the division manner of dividing the first time domain symbol set into N time domain regions is only an example, and the present embodiment does not exclude other division manners. In fig. 11 and 12, the first set of time domain symbols is formed by time domain symbols included in one period, and in another embodiment, the first set of time domain symbols may also be formed by time domain symbols included in more than one period corresponding to at least one of the sounding reference signal and the sounding reference signal resource.

Wherein the first transmission parameter may include at least one of: transmitting a wave beam, measuring frequency domain resources occupied by reference signals and measuring code domain resources occupied by the reference signals; the time domain region may also be referred to as a quasi-co-location region when the first transmission parameters include at least one of channel characteristic parameters and transmission beams.

Wherein receiving the parameters may include: a beam is received.

The second transmission parameters corresponding to different time domain regions may be the same, and the second transmission parameters may include at least one of the following information: frequency domain resources occupied by the measurement reference signals and code domain resources occupied by the measurement reference signals.

The seventh sharing parameter is a phase compensation reference signal, for example, a plurality of CSI-RS resources correspond to different radio frequency beams of the same panel, and the plurality of CSI-RS resources can share the phase compensation reference signal. In an exemplary embodiment, the terminal and the base station may agree that a plurality of CSI-RS resources sharing the phase compensation reference signal correspond to the same panel, and a plurality of CSI-RS resources corresponding to different phase compensation parameters correspond to different panels, and the terminal may select the panel for feedback based on the information, that is, there is a relationship between the configuration of the phase compensation reference signal and the configuration of the terminal feedback at this time.

The transmission parameters shared in this embodiment may include at least one of channel characteristic parameters, transmission beam parameters, reception beam parameters, frequency domain resources, comb Level (Level), comb offset, subcarrier spacing, measurement reference signal types, time domain symbol information, time domain retransmission times in one period, pattern configuration parameters, second class of time domain parameters, measurement reference signal Component (Component) index sets, multiplexing modes between measurement reference signals components, mapping relationships between measurement reference signals components and measurement reference signal ports, power parameters, and phase compensation reference signals; a quasi co-located reference signal; a set of periodic offsets; activation and deactivation information indication information.

This embodiment does not exclude other transmission parameters that may be shared. The sharing manner may adopt the manner described in the first embodiment, or may also adopt other sharing manners, which is not limited in this application.

EXAMPLE III

The present embodiment illustrates the configuration of time domain parameters in CSI-RS configuration information.

In the first configuration information of this embodiment, the time domain parameter may include at least one of the following: time domain symbol positions of various subcarrier intervals and various time domain symbol numbers. As shown in fig. 13, the subcarrier spacing transmitted by the CSI-RS is larger than the time domain symbols corresponding to other signals, and a plurality of time domain symbols with a large subcarrier spacing correspond to a time domain symbol with a small subcarrier spacing. As shown in fig. 13, one first small subcarrier spacing time domain symbol includes 4 large subcarrier spacing time domain symbols. At this time, at least one of the position and the number of the first time domain symbols occupied by the CSI-RS resource and at least one of the position and the number of the second subcarrier time domain symbols need to be configured in the time domain symbol configuration. Or, at this time, two-stage time domain information configuration is performed, at least one of the position and the number of the time domain symbols of the first subcarrier interval corresponding to at least one of the sounding reference signal resource and the sounding reference signal is configured, and then the relative position of the time domain symbols of the second carrier interval occupied by at least one of the sounding reference signal resource and the sounding reference signal in each occupied time domain symbol of the first subcarrier interval is configured.

In the second configuration information of this embodiment, one srs resource or srs corresponds to multiple types of time domain parameters; in an exemplary embodiment, the first class indicates which of a period, a half period, and a non-period the sounding reference signal resource or the sounding reference signal is. The second type represents that the first time domain symbol set corresponding to the measurement reference signal is divided into a plurality of time domain regions, and at least one of the first sending parameters and the receiving parameters corresponding to different time domain regions is different. The first time domain symbol set corresponding to at least one of the sounding reference signal and the sounding reference signal resource is formed by time domain symbols included in one period corresponding to the sounding reference signal, or the first time domain symbol set may be formed by time domain symbols included in one period, or when the sounding reference signal is a periodic, half-period sounding reference signal, the first time domain symbol set is formed by time domain symbols included in more than one period corresponding to at least one of the sounding reference signal and the sounding reference signal resource.

The first transmission parameter includes at least one of: transmitting a beam, a frequency domain resource occupied by the measurement reference signal, and a code domain resource occupied by the measurement reference signal; the time domain region may also be referred to as a quasi-co-location region when the first transmission parameter corresponds to at least one of a channel characteristic parameter and transmission beam information.

The receiving parameters include: a beam is received. The second sending parameters corresponding to the different time domain regions are the same, and the second sending parameters include at least one of the following information: and the frequency domain resources occupied by the measurement reference signals and the code domain resources occupied by the measurement reference signals.

Example four

This embodiment describes a transmission process using IFDMA.

In this embodiment, when the sounding reference signal is transmitted by using IFDMA, a time-domain repetitive pattern may be formed in the time domain, which is used for the receiving end to perform receive beam training. However, because the multiplexing modes of the beams corresponding to the sounding reference signals or the multiple sounding reference signals at the transmitting end to the IFFT (Inverse Fast Fourier Transform) unit are different, the number of trainable receive beams in the time domain is different in the same IFDMA structure.

As shown in fig. 14, the sounding reference signals correspond to 4 different comb units, and if the IFFT units of the sounding reference signals {1,2,3,4} are independent from each other (at this time, when the IFFT unit corresponding to each port performs IFFT, the frequency domain resources occupied by other ports are filled with 0), then each sounding reference signal forms 4 repeated resources in the time domain, and the receiving port can perform 4 times of receive beam training on one OFDM symbol, as shown in the time domain transmission signal pattern after IFFT in fig. 14. When the time domain units corresponding to {1,2,3,4} are not independent (at this time, the IFFT unit corresponding to each port fills up signals of other ports with the frequency domain resources occupied by other ports when performing IFFT), at this time, each port can only generate one time domain sample in the time domain, and there is no repetition phenomenon, and the receiving end cannot perform time domain repetition, as shown in the time domain transmission signal pattern after IFFT shown in the lower right of fig. 14.

In short, if the measurement reference signal is CSI-RS, and when the terminal needs to perform receive beam switching, the base station needs to inform whether the IFDMA pattern type is the first type (i.e. the time domain pattern is at the top right of fig. 14, or different ports of CSI-RS correspond to different IFFT units, or radio frequency beam units) or the second type (i.e. the time domain pattern is at the bottom right of fig. 14, or different ports of CSI-RS correspond to the same IFFT units, or the same radio frequency beam units) if the terminal needs to perform receive beam switching. When the measurement reference signal is an SRS, the base station needs to inform the terminal of the multiplexing manner of the terminal to the IFFT units of different SRS ports (corresponding to the first type or the second type), so that the terminal adopts a suitable beam to transmit a signal to the base station, and the base station performs receive beam training, for example, when the notification is the first type, different SRS ports correspond to different transmission panel groups, and when the notification is the second type, different SRS ports may correspond to the same transmission panel group. Or the terminal informs the base station whether the IFDMA structure corresponds to the first type or the second type. It can be reported as capability or as request message.

EXAMPLE five

This embodiment illustrates a case where the CSI-RS pattern includes a subcarrier location where the DMRS is located.

Symbols that may be occupied by demodulation reference signals, control channel signals, are not included in the pattern of CSI-RS in LTE, as shown in fig. 15. However, in NR, the CSI-RS is allowed to be transmitted with a partial bandwidth, and particularly, when performing beam training, the frequency domain resources that can be occupied by the measurement reference signal may be very small, and in this case, the CSI-RS may be allowed to occupy resources occupied by a second signal, where the second signal includes at least one of the following signals: demodulation reference signal, control channel signal, phase compensation reference signal.

As shown in fig. 16, on the same time domain symbol 3, there may be overlap between the demodulation reference signal port 1 and REs (Resource elements) occupied by the sounding reference signal, REs that can transmit the demodulation reference signal may be grouped into one group, REs without the sounding reference signal may be grouped into another group, and REs occupied by one sounding reference signal configuration may be grouped into only one group.

When the resources of the measurement reference signal and the second signal are the same, the two types of signals meet at least one of the following characteristics: the two types of signals are sent in a time-sharing mode; the two types of signals are sent to different communication nodes (for example, terminals corresponding to CSI-RS and DMRS are different in downlink); the two types of signals are from different communication nodes (for example, terminals corresponding to the CSI-RS and the DMRS are different in uplink).

In an exemplary embodiment, the sounding reference signal resource may occupy a resource occupied by a second signal, determined according to whether the sounding reference signal is a full bandwidth transmission; for example, the sounding reference signal may not occupy the resource occupied by the second signal when the full bandwidth transmission is performed, and the sounding reference signal may occupy the resource occupied by the second signal when the partial bandwidth transmission is performed. One way is that the number of the sounding reference signal configuration resources is the same, and is 2 sets as shown in fig. 16, but is limited according to whether the system bandwidth is full, and the other way is that whether the system bandwidth transmits the corresponding sounding reference signal configuration resources is different, and as shown in fig. 16, when the system bandwidth is full, the frequency domain resources and the time domain resources are notified separately, rather than being notified jointly. One frequency domain resource may correspond to a plurality of time domain resources.

EXAMPLE six

In an embodiment, the same SRS resource corresponds to multiple sets of time domain parameters. Wherein, the distinguishing parameter of the time domain parameters of different sets comprises at least one of the following parameters: time domain parameters of the first kind (periodic, non-periodic, half-period); a second type of time domain parameter (number of repeated transmissions). Which set or sets of time domain parameters are currently activated is indicated by signaling.

In an exemplary embodiment, the uplink beam training includes transmission beam and reception beam training (hereinafter referred to as U-1), uplink reception beam training (hereinafter referred to as U-2), and uplink transmission beam training (hereinafter referred to as U-3).

When U-2, its transmission beam is a transmission beam taken from U-1 and/or U-3, the difference between U-2 and U-1/U-3 is that its number of repeated transmissions is different.

A first embodiment of the repeated transmission times is the number of time domain symbols included in one period, where the time domain symbols include the number of first subcarrier time domain symbols and/or the number of second subcarrier time domain symbols, and one first subcarrier time domain symbol includes multiple second subcarrier time domain symbols.

The second embodiment of the number of repeated transmissions is the Level of a comb structure included in the IFDMA, and the Level of the comb structure determines the number of time-domain repeated waveforms formed after the IFFT is performed. Similar to the fourth embodiment, the same dressing structure has different repetition times of the corresponding receiving ends.

The third embodiment of the number of times of repeated transmission is whether other signals, such as data signals, control channels, and the like, are also included in the SRS symbol, when only the SRS symbol is included in the SRS symbol, and each SRS port has an IFFT unit, the time domain repetition number is an interval between frequency domain subcarriers occupied by one measurement reference signal. Otherwise there may be no duplicate feature.

The fourth embodiment of the number of repeated transmissions is whether the SRS symbol is transmitted in full bandwidth, such as IFDMA (i.e. one SRS port uniformly occupies subcarriers), but if the number of repeated partial bandwidth is 1 even if IFDMA is used, the full bandwidth is determined according to the comb Level.

The number of repeated transmissions corresponding to the measurement reference signal may also be referred to as density information. In one case, the number of repetitions is determined by a request of the root terminal, or the SRS is determined according to the capability reported by the terminal, or the number of repetitions corresponding to the CSI-RS, or the density information.

EXAMPLE seven

In the present embodiment, in the control information:

the activation state and the deactivation state are represented by the same indicator value, the first transmission of the indicator value represents activation, and the second transmission of the indicator value represents deactivation;

and/or, the new resource is activated and the old resource is deactivated by using the indication value changed.

For example, there are 4 resources, one of the 4 resources is selected by 2 bits, different transmission times with the same value indicate activation and deactivation, and a change in the indication value indicates activation of a new resource and deactivation of an old resource. The corresponding relation between the resources and the indicated value is shown in table 1, when the control information is sent for the first time, 00 represents that the resource 0 is activated, and when the control information is sent for the second time, 00 represents that the resource 0 is deactivated; or, when "00" is sent for the first time in the control information to indicate that resource 0 is activated, and when "01" is sent for the second time in the control information to indicate that resource 0 is deactivated, resource 1 is activated.

TABLE 1

Indicating bit value	(Resource)
		00	Resource 0
01	Resource 1
		10	Resource 2
11	Resource 3

The control information may be at least one of the following control information: higher layer control information (e.g., RRC control information, MAC CE control information), physical layer dynamic control information. The resource may be a measurement reference signal resource (such as a downlink CSI-RS reference signal resource, an uplink SRS resource), a reporting set resource, or a reference signal resource.

Example eight

In this embodiment, the setup testSet of periodic offsets for the reference signal, e.g. measuring the period of the reference signal as T, the set of periodic offsets being { Δ T } ₁ ,ΔT ₂ ,...,ΔT _K Preferably 0 ≦ Δ T _i T-1i ≦ 1. = 1., K, then the set of time units in one period corresponding to the set of period offsets

{n _i ,mod(n _i ,T+ΔT _i )＝0,i＝1,...,K}。

Wherein the time unit for sending the measurement reference signal is a subset of the time unit set, and/or the time unit for sending the measurement reference signal is the first N time units satisfying the sending condition in the time unit set.

Wherein, the sending condition is at least one of the following conditions: the time cell is not occupied by the second signal; the resource allocated to the sounding reference signal in the time unit does not belong to a second transmission domain; the resource allocated to the sounding reference signal in the time unit does not belong to a second domain; all of the resources allocated to the sounding reference signal in the time unit may be used for transmitting the sounding reference signal; a part of the resources allocated to the sounding reference signal in the time unit may be used for transmitting the sounding reference signal; the priority of the second signal is higher than that of the measurement reference signal, the transmission direction of the second transmission domain is different from that of the measurement reference signal, and the second domain is a protection domain between an uplink and a downlink.

For example, the measurement reference signal is a periodic or aperiodic CSI-RS, a resource allocated to the CSI-RS is occupied by a synchronization signal, or a URLLC service, or a resource allocated to the CSI-RS is allocated to an uplink transmission domain, or is allocated to a GP (uplink guard interval), at this time, the measurement reference signal cannot be transmitted in this time unit, and it needs to fall into a first time unit in the time unit set that does not have the above condition, or transmit in the first X time units that do not have the above condition, where X is a natural number. Note that if a part of resources on resources allocated to the sounding reference signal is occupied by other signals or the sounding reference signal cannot be transmitted, the sounding reference signal moves to the next time unit to transmit the sounding reference signal. Or, part of the resources which can transmit the sounding reference signal in the first time unit are firstly transmitted in the first time unit, and part of the sounding reference signal which is not transmitted in the first time unit is shifted to the second time unit for transmission.

A set of time units may similarly be present for aperiodic sounding reference signals.

The sounding reference signal may also be an uplink SRS reference signal.

Example nine

In this embodiment, it is determined whether the measured reference signal is in a subcarrier increase mode, an IFDMA mode, or a subcarrier spacing increase mode according to whether the reception beam training or the transmission beam training is performed.

Or, whether the measurement reference signal adopts the IFDMA mode or the mode of increasing the subcarrier spacing is indicated according to the control information.

Or there is a relationship between the time domain symbol type used by the sounding reference signal and the reporting type corresponding to the sounding reference signal.

Example ten

In this embodiment, there are two time domain symbols where the measurement reference signal is located, one is that each OFDM symbol has a CP, and the other is that a part of the OFDM symbol has no CP. For example, the information sent on two OFDM symbols is completely the same, after IFFT is performed, the time domain samples corresponding to the two OFDM symbols are the same, and the last bit of the previous time domain symbol can be used as the CP of the next time domain symbol, thereby saving time domain overhead.

Specifically, for example, each OFDM symbol has only a reference signal, and if the frequency domain resources occupied by the reference signal on each OFDM time domain symbol are the same and the sequences used by the reference signals are the same, the last bit of the previous time domain symbol may be used as the CP of the next time domain symbol.

In this embodiment, it is determined whether the measured reference signal has an OFDM symbol without a CP according to whether reception beam training or transmission beam training is performed.

Or, whether the measured reference signal has an OFDM symbol without a CP is indicated according to the control information.

Or, there is a relationship between whether the measured reference signal has an OFDM symbol without a CP and a reporting type corresponding to the measured reference signal.

EXAMPLE eleven

In the present embodiment, a QCL relationship is established between one SRS resource set and one SRS resource. Wherein, the reference signal and SRS resource set in SRS resource are as shown in fig. 17. One or more resources are included in the one SRS Resource set.

Now, in the NR, the beam supporting the terminal to transmit the SRS is transparent to the base station, and in this transparent manner, if the uplink beam training is divided into a plurality of stages, a first stage is coarse beam or lower overhead beam transmission training and reception, and a second stage refers to the first stage to perform uplink beam transmission training or uplink beam reception training.

For example, the transmission beam in the second stage is a refinement of the transmission beam in the first stage or an addition of Oversampling, and as shown in fig. 17, a QCL relationship between an SRS Resource (for example, one transmission beam corresponding to the first stage) and a Resource Set (for example, one transmission beam group corresponding to the second stage) is established, so that different resources in the Resource Set correspond to different refinement beams of the transmission beam in the first stage or different peripheral transmission beams of the transmission beam in the first stage.

The number of resources included in one Resource set in the QCL relationship may be obtained by at least one of the following ways: one method for obtaining the Resource set is that the base station indicates, and further the base station allocates the number of resources included in one Resource set according to the capability reported by the terminal or the request of the terminal. And the terminal determines a transmission beam according to the number of the SRS resources allocated by the base station. Considering that the performance of different transmission beams reaching the base station in the first stage is different, the number of SRS resources contained in different SRS resource sets corresponding to the different transmission beams in the first stage is allowed to be different, or the restriction is the same.

It is mentioned above that the transmit beams of the second stage may be a refinement of the transmit beams of the first stage, as illustrated in fig. 18a, or a search for beams around the transmit beams of the first stage, as illustrated in fig. 18b, in fig. 18a to 18b, the transmit beams of the first stage are indicated by dotted lines and the transmit beams of the second stage are indicated by solid lines. After the QCL relationship shown in fig. 17 is established, if the transmission beam in the second stage is transparent to the base station, the base station and the terminal need to understand uniformly, and the transmission beam in the second stage is which one of fig. 18a to 18b, so that the terminal has a reference for the selection of the transmission beam, and the base station has a reference for the subsequent measurement and scheduling of data/control. To this end, the power or other parameters may implicitly indicate the type of the beam, or indicate whether the offset between the center angles of the two-stage transmission beams is greater than 0 in the QCL relationship, or indicate which of fig. 18a to 18b the terminal requests, or indicate directly by the base station.

Example twelve

In this embodiment, in the IFDMA mode, the CSI-RS level is determined according to the number of ports included in the CSI-RS resource.

In the IFDMA mode, when one CSI-RS resource includes a plurality of ports, the comb intervals between the plurality of ports are the same. The time domain repetition times among the ports are the same.

Specifically, as shown in fig. 19 to 20, when there are only two ports on the time domain symbol, the interval between the measurement reference signals is 5 subcarriers, that is, the number of 0 padding between the measurement reference signals is 5. When 4 ports exist on the time domain symbol, the interval between the measurement reference signals is 2 subcarriers, that is, the number of 0 s filled between the measurement reference signals is 2.

As shown in fig. 19 to 20, in the IFDMA mode or the non-IFDAM mode, the mapping of the measurement reference signal to the frequency domain resource is not sequential mapping, but satisfies the characteristics of nest.

Example thirteen:

in this embodiment, the time domain repetition times corresponding to the same IFDMA pattern needs to be indicated to the terminal by the base station.

Specifically, as shown in fig. 21, the same IFDMA pattern is as shown in the left diagram of fig. 14, when IFFT units of different CSI-RS ports are independent of each other, for example, when each CSI-RS port corresponds to an analog beam, the pattern after IFFT is as shown in the upper right diagram, and there is a time domain repetition feature, so that receive beam training or transmit beam training can be performed. If the IFFT units of different CSI-RS ports are not independent, for example, each CSI-RS port corresponds to a hybrid beam, the pattern after IFFT is as shown in the lower right of the figure. In short, the number of the receiving beams that can be made by the same IFDMA pattern is variable.

In this case, the time-domain repetition beams after IFFT in the IFDMA method are as follows: one is the number of repetitions is based on the number of subcarriers spaced between the same ports (e.g. each port in fig. 21 occupies one subcarrier per 4 subcarriers spaced), and the other is the number of 0 s padded between all ports (i.e. when ports {1,2,3,4} are combined, there is no space between ports, i.e. there is no sun duplication). As shown in fig. 21, each port occupies one subcarrier every 4, and the port {1,2} occupies one subcarrier every 2 in the integrated view. Whether the number of repetitions of an IFDMA is based on one of the above two criteria requires the base station to indicate to the terminal.

When the SRS measures the reference signal, the terminal may apply to the base station.
