The present disclosure relates to the field of communication, for example, an information determination method and apparatus, a signal reception method and apparatus, a signal transmission method and apparatus, a storage medium and an electronic apparatus.
An aperiodic measurement reference signal is triggered by downlink control information (DCI). In a communication system based on radio beams, the aperiodic measurement reference signal needs to be received by using a suitable receive beam. A certain time interval is required between the time when a terminal decodes the DCI and the time when the receive beam indicated by the DCI is used to receive an aperiodic-channel state information-reference signal (AP-CSI-RS). The receive beam of the aperiodic measurement reference signal cannot be determined when the time interval between the DCI and the aperiodic measurement reference signal is less than a target time interval. On the other hand, many channel state information-reference signal (CSI-RS) resources exist in new radio (NR), and the signaling overhead for notifying the aperiodic measurement reference signal is large, causing a large system load. Moreover, some parameter configurations of the aperiodic measurement reference signal are unreasonable and unclear, making the system unable to run and causing confusion in the understanding of the terminal.

The quasi-co-location reference signal information is determined in different manners according to different first information. The quasi-co-location reference signal information may be determined in many different manners or combinations.
For example, when the first information includes the relationship between the first threshold and the time interval, the step of determining the quasi-co-location reference signal information of the aperiodic measurement reference signal resource according to the first information may include determining the quasi-co-location reference signal information of the aperiodic measurement reference signal resource according to the relationship between the first threshold and the time interval and according to a target rule.

When the time interval is greater than or equal to the first threshold, aperiodic measurement reference signal resources in the aperiodic measurement reference signal resource set including the aperiodic measurement reference signal resource are not required to satisfy a quasi-co-location relationship.
When the time interval is greater than or equal to the first threshold, each measurement reference signal resource in the time unit where the aperiodic measurement reference signal resource is located corresponds to one quasi-co-location reference signal separately.

The quasi-co-location reference signal of one signal being acquired according to the quasi-co-location reference signal of another signal indicates that part or all of the quasi-co-location reference signals of one signal are acquired according to part or all of the quasi-co-location reference signals of another signal. For example, each signal is associated with two quasi-co-location reference signals, and different quasi-co-location reference signals are associated with different quasi-co-location parameter sets. In one case, both quasi-co-location parameters of one signal are acquired according to the quasi-co-location reference signals of another signal. In another case, one of the quasi-co-location parameters of one signal is acquired according to one quasi-co-location reference signal of another signal.

The information determination method in the embodiment is illustrated in conjunction with the examples described below.
In a communication system based on radio beams (for example, at high frequency bandwidth, not excluding the case where radio beams may also be used at low frequency bandwidth), when an aperiodic measurement reference signal (for example, AP-CSI-RS) is received, it is necessary to determine the receive beam of the AP-CSI-RS, especially the radio receive beam.
However, from DCI to the AP-CSI-RS, it is necessary to consider the delay of the terminal decoding the DCI and the delay of beam handover. Therefore, for not all the radio frequency receive beams of the AP-CSI-RS, at least one of the receive beam or large-scale information of the AP-CSI-RS can be obtained according to the quasi-co-location reference signal (QCL-RS) of the AP-CSI-RS indicated in the DCI.
The AP-CSI-RS in new radio (NR) is activated in a manner as shown in
However, when the time interval between the AP-CSI-RS and the DCI that schedules the AP-CSI-RS is less than a first threshold K, the QCL information of the AP-CSI-RS, especially the QCL reference signal information of the spatial Rx parameter associated with the AP-CSI-RS, that is, the radio receive beam information of the AP-CSI-RS, can be determined in at least one of the manners described below.
1) Manner one of acquiring a quasi-co-location reference signal of an aperiodic measurement reference signal is described as below.
According to the relationship between the time interval between the DCI and the AP-CSI-RS and the first threshold K, it is determined whether the resources in the set share a quasi-co-location reference signal. As shown in
The {AP-CSI-RS1, AP-CSI-RS2} in set 1 may share the quasi-co-location reference signal in a plurality of manners. One sharing manner is that the QCL-RSs associated with all quasi-co-location parameters of AP-CSI-RS1 and AP-CSI-RS2 are the same, for example, the QCL-RS of AP-CSI-RS1 and AP-CSI-RS2 with respect to {Doppler shift, Doppler spread, average delay, delay spread} is QCL-RS1, and the QCL-RS of AP-CSI-RS1 and AP-CSI-RS2 with respect to {spatial Rx parameter} is QCL-RS2. Another sharing manner is that the QCL-RSs associated with a quasi-co-location parameter of the spatial Rx parameter, of AP-CSI-RS1 and AP-CSI-RS2 are the same (for example, QCL-RS3), and other quasi-co-location parameters of AP-CSI-RS1 are acquired according to the indication in the DCI, for example, the QCL-RS of other quasi-co-location parameters of AP-CSI-RS1 is QCL-RS4. The QCL-RS associated with other quasi-co-location parameters of AP-CSI-RS2 are acquired according to the indication in the DCI, for example, the QCL-RS of other quasi-co-location parameters of AP-CSI-RS2 is QCL-RS5. Other quasi-co-location parameters include at least one of: Doppler shift, Doppler spread, average delay, delay spread or an average gain.
The time interval between the DCI and the AP-CSI-RS may be at least one of the time intervals described below.
(1) Time interval one: time unit offset between the DCI and an AP-CSI-RS set.
The unit of time interval one is a time unit, for example, a slot, that is, the time interval one is an offset configured for an AP-CSI-RS set, where the time unit is a slot. For example, an offset is configured to be 1 in the AP-CSI-RS set, indicating a time offset of one slot between the DCI and the AP-CSI-RS. For example, the DCI is in a time domain symbol k1 in slot n and the AP-CSI-RS is in a time domain symbol k2 in slot (n+1), where k1 and k2 may be any combination without limitation.
(2) Time interval two: time interval between the DCI and the first time domain symbol in an AP-CSI-RS set.
The unit of time interval two is a time domain symbol. As shown in
(3) Time interval three: time interval between the DCI and the last time domain symbol in an AP-CSI-RS set.
The unit of time interval three is a time domain symbol. As shown in
(4) Time interval four: interval between the DCI and the first time domain symbol of each AP-CSI-RS resource.
For example, each AP-CSI-RS resource in set 1 occupies merely one time domain symbol, and thus the time interval between DCI and AP-CSI-RS1 is 16 time domain symbols, and the time interval between DCI and AP-CSI-RS2 is 19 time domain symbols. Similarly, time interval four may also be an interval between the DCI and the last time domain symbol of each AP-CSI-RS resource.
QCL-RS1 and QCL-RS2 in sharing manner one or QCL-RS3 in sharing manner two may be referred to default quasi-co-location reference signals. The default quasi-co-location reference signals may be acquired in the manners described below.
The default quasi-co-location reference signal is acquired according to the quasi-co-location reference signal of a control resource satisfying a second predetermined characteristic in a time domain symbol closest to an AP-CSI-RS set among time domain symbols where a control resource satisfying a first predetermined characteristic is included. In this manner, the default quasi-co-location reference signals of different sets in the same slot may be different. As shown in
The default quasi-co-location reference signal is acquired according to the quasi-co-location reference signal of a control resource satisfying a second predetermined characteristic in a time unit closest to an AP-CSI-RS set among time units where a control resource satisfying a first predetermined characteristic is included. In this manner, the default quasi-co-location reference signals of different sets in the same slot are the same. As shown in
The quasi-co-location reference signals of M AP-CSI-RS resource (aperiodic measurement reference signal resource) groups are determined according to M control resources.
M AP-CSI-RS resource groups belong to one AP-CSI-RS resource set, or M AP-CSI-RS resource groups belong to M AP-CSI-RS resource sets.
The M control resources are M control resources included in the time unit set closest to an AP-CSI-RS resource group among the time unit sets where at least M control resources are included. The M control resources satisfy at least one of the following characteristics: the intersection of time domain resources occupied by the M control resources is not null, and the M control resources are M control resources having the lowest control resource index in the intersection of time domain resources.
The correspondence between the M AP-CSI-RS resource groups and the M control resource groups is obtained through signaling information or a predetermined rule, for example, the i-th AP-CSI-RS resource group is acquired according to the quasi-co-location reference signal of the i-th control resource. 1≤i≤M and i is a positive integer.
A control resource is a control resource set (CORESET) or a search space set, and the quasi-co-location reference signal of the control resource is the quasi-co-location reference signal of the demodulation reference signal of the control resource.
In the embodiment, the quasi-co-location reference signal of one signal is acquired according to the quasi-co-location reference signal of another signal, which indicates that the quasi-co-location reference signal of one signal associated with a type of quasi-co-location parameter is acquired according to the quasi-co-location reference signal of another signal associated with a type of quasi-co-location parameter.

The time interval between the second channels or signals and the control information scheduling these channels or signals is greater than or equal to a second threshold. When the second channel is a data channel, the time interval between the data channel and the control information scheduling the data channel may also be less than the second threshold. In this case, the data channel is referred to as a potential data channel.
The first threshold and the second threshold may be the same or different.
When the intersection is not null, the quasi-co-location reference signal of an aperiodic measurement reference signal resource satisfies at least one of the following characteristics: measurement reference signal resources in an aperiodic measurement reference signal resource set share a quasi-co-location reference signal; the quasi-co-location reference signal of the aperiodic measurement reference signal resource is acquired according to the quasi-co-location reference signal of a control resource satisfying the second predetermined characteristic in a time unit closest to the aperiodic measurement reference signal resource among time units where a control resource satisfying the first predetermined characteristic is included; or the quasi-co-location reference signal of the aperiodic measurement reference signal resource is acquired according to the quasi-co-location reference signal of a channel resource satisfying the second predetermined characteristic in a time unit closest to the aperiodic measurement reference signal set where the aperiodic measurement reference signal resource is located among time units where a control resource satisfying the first predetermined characteristic is included.

The quasi-co-location reference signal of the aperiodic measurement reference signal resource is acquired according to whether the intersection is null, and the time interval between the aperiodic measurement reference signal resource and the control information scheduling the aperiodic measurement reference signal resource is less than the first threshold.
When the first threshold is mainly used for the terminal to decode the DCI and hand over a receive beam, the terminal receives an AP-CSI-RS by using an active receive antenna, and the first threshold is the first value. When the first threshold is mainly used for the terminal to decode the DCI and hand over a receive beam and the receive antenna of the terminal corresponding to the AP-CSI-RS is in an inactive state, the terminal also needs to activate the antenna before receiving the AP-CSI-RS, and the first threshold is the second value. The first value and the second value are two different values, and the first value is less than the second value.
Which value the first threshold is to take (for example, which of the first value and the second value, not excluding the possibility that the first threshold has more than two values) may be acquired in at least one of the manners described below.
Manner one of acquiring the first threshold: the first threshold is acquired according to signaling information, where the signaling information includes information about the first threshold. For example, the first threshold is configured in an AP-CSI-RS resource, or in an AP-CSI-RS resource set or in an AP-CSI-RS resource setting. Similarly, the first threshold may also be acquired according to the set index information of the aperiodic measurement reference signal set where the aperiodic measurement reference signal resource is located, or the first threshold may be acquired according to the aperiodic measurement reference signal resource index information.
Manner two of acquiring the first threshold: the first threshold is acquired according to parameter information associated with an aperiodic measurement reference signal resource. The parameter information includes at least one of: a QCL-RS or repetition information configured in a set where the aperiodic measurement reference signal resource is located. When repetition is configured to be on, different AP-CSI-RS resources in a set have the same transmit beams, and the terminal performs receive beam training. When repetition is configured to be off, different AP-CSI-RS resources in a set have different transmit beams, and the receive beams of the terminal are fixed. Therefore, when repetition is configured to be off, the first threshold may be smaller, and when repetition is configured to be on, the first threshold may be larger.
Manner three of acquiring the first threshold: the first threshold is acquired according to group information associated with the aperiodic measurement reference signal resource. The group information may be grouping information of measurement reference signal indication information fed back when the channel state information of the terminal is fed back or group information corresponding to the aperiodic measurement reference signal indicated by a base station. Different group information is associated with different receive antenna groups. The first threshold is a third value when the group information corresponding to DCI or a downlink signal in a time domain symbol closest to an AP-CSI-RS is the same as the group information corresponding to the AP-CSI-RS. The first threshold is a fourth value when the group information corresponding to DCI or a downlink signal in a time domain symbol closest to an AP-CSI-RS is different from the group information corresponding to the AP-CSI-RS. The third value is less than the fourth value.
Manner four of acquiring the first threshold: the first threshold is acquired according to information about an activation state of a receive antenna associated with the aperiodic measurement reference signal resource. The first threshold value is the first value if the receive antenna of the AP-CSI-RS resource is in an active state, and the first threshold value is the second value if the receive antenna of the AP-CSI-RS resource is in an inactive state. Similarly, the first threshold may also be determined according to the activation state of the current receive antenna of the terminal. The activation state of the receive antenna indicates the time domain position of the AP-CSI-RS resource in the DCI.
Manner five of acquiring the first threshold: the first threshold is determined according to whether a data channel or signal exists in a time domain symbol or at a time moment where the aperiodic measurement reference signal resource is located. The first threshold is a seventh value when the downlink channel or signal exists, and the first threshold is an eighth value when no downlink channel or signal exists. The seventh value is greater than the eighth value.
Manner six of acquiring the first threshold: the first threshold is determined according to whether the configuration information of the QCL-RS of other downlink channels or signals in a time domain symbol or at a time moment where the aperiodic measurement reference signal resource is located and the QCL-RS of the aperiodic measurement reference signal resource satisfy a quasi-co-location relationship. The first threshold is a ninth value when the quasi-co-location relationship is satisfied, and the first threshold is a tenth value when the quasi-co-location relationship is not satisfied. The ninth value is greater than the tenth value.
Other downlink channels or signals are previously scheduled downlink channels or signals. For example, the time interval between the control information scheduling these downlink channels or signals and the downlink channels or signals is greater than or equal to a predetermined threshold, or these channels or signals are triggered by higher-layer signaling, such as periodic measurement reference signals, control channels and semi-persistent data channels. Of course, other downlink channels or signals may also be downlink channels or signals scheduled by other DCI. The time interval between other DCI and downlink channels or signals is less than the predetermined threshold.
Manner seven of acquiring the first threshold: the first threshold is determined according to whether to be in an activation state of a discontinuous reception period, that is, whether the MAC layer of a terminal in the DRX period is in an active state, or whether the interval time domain between the time domain symbol where the DCI is located and the wake-up starting position of the DRX state is greater than a predetermined value. For example, the first threshold is a larger value if the time domain symbol where the AP-CSI-RS is located is in the DRX state, or the first threshold is a larger value if the time interval between the time domain symbol where the DCI is located and the wake-up starting position in the DRX is less than the predetermined value, for example, if the DCI is in the just wake-up position.
Manner eight of acquiring the first threshold: the first threshold is acquired according to whether a value of fifth capability information reported by a terminal belongs to a predetermined set. When the value of the fifth capability information reported by the terminal belongs to the predetermined set, the first threshold is the value of the fifth capability information reported by the terminal. When the value of the fifth capability information reported by the terminal does not belong to the predetermined set, the first threshold is the value of the first capability information reported by the terminal.
The fifth capability information includes one of: the second capability information to the fourth capability information. The first capability information to the fourth capability information satisfy the characteristics described below.
The first capability information reported by the terminal is used for indicating a minimum time interval required by the communication node to detect physical layer control information and apply spatial domain quasi-co-location reference signal information indicated in the physical layer control information for receiving a data channel.
For the second capability information reported by the terminal, the second capability information is used for indicating a minimum time interval required by the communication node between a time of physical layer control information and a time when spatial domain quasi-co-location reference signal information indicated in the physical layer control information is used to receive the aperiodic measurement reference signal.
For the third capability information reported by the terminal, the third capability information is used for indicating a minimum time interval required by the communication node from a time when the communication node detects physical layer control information to a time when spatial domain quasi-co-location reference signal information indicated in the physical layer control information is used to receive the aperiodic measurement reference signal. The communication node receives the aperiodic measurement reference signal by using an inactive antenna.
For the fourth capability information reported by the terminal, the fourth capability information is used for indicating: when the communication node receives an aperiodic measurement reference signal, a minimum time interval between the aperiodic measurement reference signal and physical layer control information scheduling the aperiodic measurement reference signal.
The embodiment further provides a signal reception method executed on the mobile terminal described above.
In step S602, parameter information of a measurement reference signal is determined according to a predetermined rule.
In step S604, the measurement reference signal is received according to the determined parameter information.
The step of determining the parameter information of the measurement reference signal according to a predetermined rule includes that the communication node does not desire to receive parameter configuration information of a measurement reference signal that does not satisfy the predetermined rule, where the communication node is a communication node that receives the measurement reference signal.

The signal reception method in the embodiment is illustrated in conjunction with the examples described below.
In the embodiment, parameter information of a measurement reference signal is determined according to an agreed rule, and the measurement reference signal is received according to the parameter information. The step of determining the parameter information of the measurement reference signal includes that the parameter information of the measurement reference signal needs to satisfy the agreed rule.
The time offset information of the AP-CSI-RS is configured in the AP-CSI-RS set, and the time offset that may be configured in the AP-CSI-RS set is within the range of 0 to 4. The time offset indicates the time unit offset between the time unit where the DCI scheduling the AP-CSI-RS and the time unit where the AP-CSI-RS is located. For example, an offset of 0 indicates that DCI and the AP-CSI-RS are in the same time unit. In the embodiment, a time unit may be a subframe, a slot, or a time unit in which a predetermined number of time domain symbols is included. However, for the capability of a user equipment (UE), for example, a certain delay exists between the time when the terminal decodes the DCI and the time when the QCL-RS indicated in the DCI is used to receive the AP-CSI-RS. If the AP-CSI-RS is received by using an inactive receive antenna, the terminal needs to decode the DCI and activate the receive antenna before receiving the AP-CSI-RS. The minimum time interval between the DCI and the AP-CSI-RS reported in the capability information report of the UE (or the minimum time interval required for the QCL-RS indicated in the DCI to be applied to the AP-CSI-RS) includes {224, 336} time domain symbols. When the capability information reported by the terminal is 224 or 336, it is necessary to determine which AP-CSI-RS sets/AP-CSI-RS resources adopt these offsets, Such determination may be performed in the manners described below.
Manner one: └x/Ns┘ x∈{224,336} time offsets are adopted for a resource in a set having a predetermined set ID among AP-CSI-RS sets, where x∈{224,336} denotes the capability reported by the terminal, Ns denotes the number of time domain symbols included in one time unit, and └⋅┘ denotes a round-down operation. Ns is 14 when a Normal cyclic prefix (NCP) is adopted. Ns is 12 when an extended cyclic prefix is adopted. The preceding time offset is └x/Ns┘. In this case, the efficiency is high, but it cannot be ensured that the time interval between DCI and the AP-CSI-RS resource in the AP-CSI-RS set is greater than or equal to x. Therefore, ┌x/Ns┐ may also be adopted for the time offset. ┌⋅┐ denotes a round-up operation. For example, the time offset when the AP-CSI-RS set ID is the lowest is └x/Ns┘ or ┌x/Ns┐. If └x/Ns┘Ns+y≥x, the time offset is └x/Ns┘; otherwise, the time offset is ┌x/Ns┐, where y denotes a time domain symbol index of the first time domain symbol occupied by the AP-CSI-RS in one slot. The time offset when the AP-CSI-RS set ID is the lowest in a CC/BWP is a predetermined value. The predetermined value is acquired based on the capability information reported by the terminal. The embodiment does not exclude specifying the time offset when the AP-CSI-RS set ID/predetermined set ID (such as 2) is the highest in a CC/BWP as the predetermined value. Similarly, the time offset may also be determined according to an AP-CSI-RS resource ID. In this case, the unit of the time offset is a time domain symbol. For example, the time offset for the AP-CSI-RS resource ID with one of the highest resource ID, the lowest resource ID, or a predetermined resource ID is at least x, and the true offset is determined according to the time domain symbol position occupied by the AP-CSI-RS in the slot.
According to the time offset when the AP-CSI-RS set ID is the highest/the set ID (such as 2) is predetermined in a CC/BWP and when the configuration of the repetition in the set satisfies a predetermined condition, the time offset of the set is a predetermined value. The configuration of the repetition satisfying the predetermined condition includes at least one of the following: repetition information is configured in the set, repetition information is not configured in the set, a repetition value is on or a repetition value is off. When repetition in a set is on, the terminal assumes that the spatial transmission filtering parameters of the resources in the set are the same; when repetition in a set is off, the terminal assumes that the spatial transmission filtering parameters of the resources in the set are different. Repetition may also be referred to as a transmission filtering parameter control parameter.
Manner two: the time offset information of an aperiodic measurement reference signal is determined according to the activation state of the reception resource associated with the aperiodic measurement reference signal. If the receive antenna is in an active state, the time offset is the time offset configured in the AP-CSI-RS set where the aperiodic measurement reference signal is located. If the receive antenna is in an inactive state, the time offset is the time offset, └x/Ns┘ or ┌x/Ns┐, configured in the AP-CSI-RS set where the aperiodic measurement reference signal is located.
Manner three: if a resource set associated with an aperiodic measurement reference signal resource is not configured with time offset information and an aperiodic measurement reference signal is configured with a quasi-co-location reference signal associated with a spatial Rx parameter, the time offset of the aperiodic measurement reference signal resource is a predetermined value, for example, the time offset is └x/Ns┘ or ┌x/Ns┐.
Manner four: determination is performed according to whether the time domain symbol position configured in the AP-CSI-RS resource is within a predetermined range. For example, when the last time domain symbol in one slot is included in the time domain symbol position and the capability information reported by the terminal is 224 time domain symbols, the time offset of the AP-CSI-RS resource/the set where the AP-CSI-RS resource is located is └x/Ns┘ or ┌x/Ns┐. Similarly, whether the combination of the time domain symbol position configured in the AP-CSI-RS resource and the time offset configured in the set satisfies an agreed condition may also be adopted, and then the time offset of the AP-CSI-RS resource/the set where the AP-CSI-RS resource is located is └x/Ns┘ or ┌x/Ns┐. For example, one set includes an AP-CSI-RS resource occupying the last time domain symbol in one slot, and the time offset of the set is xl (for example, 4 or another value), and then the time offset of the set where the AP-CSI-RS resource is located is └x/Ns┘└x/Ns┘ or ┌x/Ns┐. x∈{224,336} is the capability reported by the terminal.
Manner five: A time offset is determined according to information about a threshold configured in a set. When the interval between the DCI and the AP-CSI-RS is less than the threshold, the first type of method is used to acquire the quasi-co-location reference signal of the AP-CSI-RS. When the interval between the DCI and the AP-CSI-RS is greater than or equal to the threshold, the second type of method is used to acquire the quasi-co-location reference signal of the AP-CSI-RS.
The time offset information of the aperiodic measurement reference signal is acquired according to the capability information reported by the terminal. The time offset information is └x/Ns┘ or ┌x/Ns┐ and may of course also be directly specified. When the reported capability information is 224 time domain symbols, the time offset is 16. When the reported capability information is 336 time domain symbols, the time offset is 24.
The frequency domain bandwidth part (BWP) information of a CSI-RS resource ID in the NR is configured in the CSI-RS resource setting. When merely CC information and CSI-RS resource ID information are given, the BWP information of the CSI-RS resource ID cannot be determined. Therefore, at least one of the agreed rules described below may be provided.
Rule one: if a measurement reference signal resource is not configured with frequency domain bandwidth part information (or a measurement reference signal is of a predetermined type, for example, the measurement reference signal belongs to a beam failure detection reference signal set q0, the measurement reference signal belongs to a candidate reference signal set q1 or the measurement reference signal is a radiolink monitoring (RLM) reference signal, then the frequency domain bandwidth part of a measurement reference signal resource is a frequency domain bandwidth part among one or more active frequency domain bandwidth parts, or the intersection of the frequency domain resources included in the active frequency domain bandwidth part and the frequency domain resources configured in the measurement reference signal resource is not null, and/or the intersection of the set of time resources in which the active frequency domain bandwidth part is in an active state and the time domain resources configured in the measurement reference signal resources is not null. That is, the active frequency domain bandwidth part intersects with the PRB resource/time domain resource (the time domain resource is obtained according to a period offset and the time domain symbol position) configured in the configuration information of the measurement reference signal resource.
A measurement reference signal of a predetermined type includes at least one of a measurement reference signal for beam failure detection, a candidate reference signal resource, a measurement reference signal for link detection or a measurement reference signal not configured with frequency domain bandwidth part information.
Rule two: configuration information about frequency domain bandwidth parts in a set of more than one measurement reference signal resource sets where a same measurement reference signal resource index is located is the same. For example, a resource ID is included in a plurality of resource settings, and then the BWP information in the plurality of resource settings is the same.
Rule three: one measurement reference signal resource index is associated with information about merely one frequency domain bandwidth part in one CC.
Rule four: one measurement reference signal resource is included at least in one set of measurement reference signal resource sets. Therefore, the BWP information of a measurement reference signal resource can be obtained according to the BWP information in the set (that is, resource setting) of measurement reference signal resource sets.
Rule five: when a measurement reference signal resource is configured in the spatial filtering parameter information of a transmitted signal, the spatial filtering parameter information includes information about the frequency domain bandwidth part where the measurement reference signal resource is located. For example, a CSI-RS resource ID is configured in SpatialRelationInfo of a sounding reference signal (SRS)/PUCCH, and BWP information further needs to be configured in SpatialRelationInfo.
For the trigger mechanism of an AP-CSI-RS as shown in
Predetermined rule one: a quasi-co-location reference signal of an aperiodic measurement reference signal resource is determined according to the time offset information in an aperiodic measurement reference signal resource set. For example, in the same trigger state, the same aperiodic measurement reference signal resource index (resource ID) is associated with more than one aperiodic measurement reference signal resource set (resource set).
If different sets are associated with different associatedconfigInfo/report setting information and the time offsets in more than one set are the same, one aperiodic measurement reference signal resource index is associated with the same quasi-co-location reference signal in more than one aperiodic measurement reference signal set; if the time offsets in more than one set are different, one aperiodic measurement reference signal resource index may be associated with a plurality of quasi-co-location reference signals in more than one aperiodic measurement reference signal set, that is, one quasi-co-location reference signal is associated with the resource index separately in each set. The preceding scheme may also be referred to as that whether the quasi-co-location reference signals of the same resource ID associated with different associatedconfigInfo/report settings in the same trigger state are the same needs to be determined according to whether the time offsets configured for the same resource ID in these pieces of associatedconfigInfo/report settings are the same.
Predetermined rule two: the quasi-co-location reference signals of aperiodic measurement reference signal resources having the same resource index and belonging to the same CC at the same time moment have the same configuration. That is, aperiodic measurement reference signal resources having the same resource index and belonging to the same CC at the same time moment cannot be associated with more than one quasi-co-location reference signal. For example, the quasi-co-location reference signals of the same resource in the same time domain symbol set in one CC need to have the same configuration. Otherwise, the terminal cannot make a determination since the same resource is associated with a plurality of quasi-co-location reference signals. Alternatively, when a plurality of quasi-co-location reference signals associated with the same resource are different, the quasi-co-location reference signal of the AP-CSI-RS is determined by using the quasi-co-location reference signal configured in the agreed associatedconfigInfo/report setting.
Predetermined rule three: configuration information of frequency domain bandwidth parts in a set of a plurality of measurement reference signal resource sets where a same aperiodic measurement reference signal resource index is located is the same. For example, the same resource ID is included in different resource settings, but the BWP configuration information in these resource settings is different, which will cause the terminal to be unable to receive the CSI-RS.
The same time moment includes the same time domain symbol, the same slot or the same subframe.
Predetermined rule four: One aperiodic measurement reference signal resource is included at least in one set of aperiodic measurement reference signal sets, so that the BWP information of such aperiodic measurement reference signal can be determined.
On the other hand, since the time offset of the AP-CSI-RS is determined in the resource set, the following agreement needs to be provided for the BWP: an aperiodic measurement reference signal resource is included in at least one aperiodic measurement reference signal set.
In the embodiment, when a measurement reference signal is of a predetermined type, the parameter of the measurement reference signal satisfies a predetermined rule. The predetermined type includes a measurement reference signal for beam failure detection (for example, a terminal detects a reference signal in a reference signal set q0 for beam failure detection so as to detect whether a beam failure event occurs), a candidate reference signal (after the terminal detects the beam failure event, a reference signal is selected from a candidate reference signal set, and it may be considered that different reference signals correspond to different transmit beam of a base station), a measurement reference signal for link detection (that is, for RLM detection) and a measurement reference signal not configured with frequency domain bandwidth part information. The predetermined rule includes at least one of the rules described below.
Rule one: in a case where a measurement reference signal resource is of a predetermined type, a frequency domain bandwidth part of the measurement reference signal resource is D frequency domain bandwidth parts, where D is a positive integer greater than or equal to 1. A frequency domain resource configured in a measurement reference signal intersects with a frequency domain resource in each frequency domain bandwidth part among D frequency domain bandwidth parts. The time domain resource obtained by the measurement reference signal according to a time domain parameter (such as a period, a time offset, a time domain symbol occupied in a slot) intersects with the time domain resource in an active state in the frequency domain bandwidth part. The D frequency domain bandwidth parts belong to one CC, or the D frequency domain parts at least include a default frequency domain bandwidth part or an initial bandwidth part.
Rule two: in a case where a measurement reference signal resource is of a predetermined type, an intersection of a frequency domain resource configured in a measurement reference signal resource and a frequency domain resource included in each frequency domain bandwidth part in one frequency domain bandwidth part set is not null. The one frequency domain bandwidth part set refers to all frequency domain bandwidth parts included in one CC. Alternatively, the one frequency domain bandwidth part set includes at least one of a default frequency domain bandwidth part or an initial bandwidth part.
Rule three: in a case where a measurement reference signal resource is of a predetermined type, a frequency domain resource span of the measurement reference signal resource is one frequency domain bandwidth. For example, the frequency domain resource span is one predetermined frequency domain bandwidth part (BWP) or one CC. One frequency domain bandwidth herein is one BWP or one CC. The frequency domain span of a measurement resource indicates the number of PRBs included between the highest PRB and the lowest PRB. The measurement reference signal occupies resources in one PRB per d PRBs in the frequency domain resource span. As shown in
In the embodiment, in a case where a first-type parameter of a measurement reference signal resource is not configured, the first-type parameter of the measurement reference signal resource takes a predetermined value. The first-type parameter includes at least one of: a frequency domain span of the measurement reference signal resource or a quasi-co-location reference signal of the measurement reference signal resource.
For example, the frequency domain span of the measurement reference signal is the frequency domain span included in the frequency domain bandwidth where the measurement reference signal is located, where one frequency domain bandwidth is one CC or one BWP. When the frequency domain span of the measurement reference signal is not configured, the frequency domain span is the number of PRBs included in the CC or BWP where the CSI-RS is located. For the CSI-RS, one of every d PRBs in the frequency domain span includes an RE occupied by the CSI-RS, as shown in
The quasi-co-location reference signal of the measurement reference signal is a quasi-co-location reference signal of a predetermined item in a list of quasi-co-location reference signals configured in a frequency domain bandwidth, such as a quasi-co-location reference signal included in a first item in a TCI pool configured in the CC/BWP.
The quasi-co-location reference signal of the measurement reference signal is a quasi-co-location reference signal of a predetermined control resource. For example, the quasi-co-location reference signal of the measurement reference signal is a quasi-co-location reference signal of the CORESET having the lowest CORESETID in the time unit closest to the measurement reference signal among the time units including control resource of predetermined CC/BWP.
The above is to take a specific value when the first-type parameter of the measurement reference signal is not configured. It may be defined that the first-type parameter of the measurement reference signal takes a predetermined value when the first-type parameter of the measurement reference signal is not configured and the value of the second-type parameter of the measurement reference signal resource meets a predetermined condition. The value of the second-type parameter of the measurement reference signal resource meeting a predetermined condition includes what is described below.
Condition one: no spatial transmission filtering parameter is configured in a measurement reference signal resource set where the measurement reference signal resource is located. The spatial transmission filtering parameter is a repetition parameter. When the repetition parameter is configured, the measurement reference signal in the set is a measurement reference signal for beam management.
Condition two: a spatial transmission filtering parameter in a measurement reference signal resource set where the measurement reference signal resource is located is configured to be off.
Condition three: a spatial transmission filtering parameter in a measurement reference signal resource set where the measurement reference signal resource is located is configured to be on.
Condition four: a time domain behavior of the measurement reference signal resource is of a predetermined type. The time domain behavior includes a periodic time domain behavior, a half-periodic time domain behavior and an aperiodic time domain behavior. For example, when the quasi-co-location parameter of the aperiodic measurement reference signal is not configured, a predetermined value may be adopted.
Condition five: reporting information associated with the measurement reference signal resource satisfies a predetermined characteristic. For example, the type of reporting information in reporting associated with the CSI-RS is ‘none’, that is, channel state information is not reported.
The embodiment further provides a signal transmission method executed on the mobile terminal described above.
