Detailed Description

To facilitate understanding of the embodiments of the present application, the following technical points are introduced:

1. regarding beam recovery mechanisms:

for high-band millimeter wave communication, if the beam is blocked, communication interruption is easily caused. Therefore, there is a need to design a beam restoration mechanism that can quickly recover from beam occlusion, ensuring the reliability and robustness of control channel transmissions.

The existing beam restoration mechanism includes 3 main steps:

step 1: the UE detects the occurrence of a beam failure event;

step 2: the UE adopts a non-competitive random access process, and reports a beam failure event and suggested new candidate beam information to a base station (namely, msg 1) through a pre-allocated physical random access channel (Physical Random Access Channel, PRACH) channel;

Step 3: the base station transmits a physical downlink control channel (Physical Downlink Control Channel, PDCCH) (i.e., msg 2) with a new candidate beam proposed by the UE in a beam-recovery control resource set (CORESET). When the UE detects the PDCCH, the reported beam failure event and the new candidate beam may be considered to be correctly received by the base station.

In step 1, a base station configures a (1+.a+.2) reference signals for beam failure detection for a UE. The UE determines whether the downlink control channel meets the reception quality requirement by measuring the reference signals of the a beams. If the channel quality of all A beams is below the established threshold, the UE will consider a beam failure event to occur.

In step 2, in order to enable the UE to report new candidate beams, the base station needs to configure B (b≡1) reference signals for beam recovery for the UE, each reference signal corresponds to one candidate beam, and configures corresponding physical random access channel (Physical Random Access Channel, PRACH) resources for each candidate beam. When a beam failure event occurs, the UE selects a new candidate beam for beam recovery by measuring a set of candidate beams, and a specific preamble sequence occurs through PRACH resources corresponding to the candidate beam.

Before the 2 steps of beam recovery, the base station also needs to configure M (M is greater than or equal to 1) radio link interception reference signals for the UE, wherein each reference signal corresponds to one downlink beam direction. The UE may have N reception beams. The UE measures the M shaped reference signals through the N receive beams, respectively, and selects an appropriate receive beam. Therefore, a total of m×n beam pairs need to be measured between the base station and the UE to find the best transmit-receive paired beam. From the viewpoint of saving the overhead, the channel quality information (such as reference signal received power (Reference Signal Receiving Power, RSRP), signal-to-interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) and/or sequence number) of all M transmission beams are not required to be reported to the base station, and L transmission beams can be selected to be reported (1 l.ltoreq.m).

In the prior art, how the base station side determines a beam failure detection reference signal set (including a reference signals) and a beam recovery reference signal set (including B reference signals) according to channel measurement results of L reference signals reported by the UE, belongs to an implementation algorithm of the base station side.

2. Reporting information about channel measurement:

in a New Radio (NR) system, channel state information (Channel State Information, CSI) may include: channel quality indication (Channel Quality Indication, CQI), precoding matrix indication (Precoding Matrix Indicator, PMI), channel state information reference signal (Channel State Information Reference Signal, CSI-RS) resource indication (CRI), SS/PBCH block resource indication (SSBRI), layer Indication (LI) resource indication (resource indication, RI), and Layer 1reference signal received power (Layer 1Reference Signal Received Power,L1-RSRP) and Layer 1signal to interference plus noise ratio (Layer 1Signal to Interference plus Noise Ratio,L1-SINR). Wherein CRI, SSBRI, L-RSRP and L1-SINR are used for beam management, wherein CRI, SSBRI indicate beam index and L1-RSRP and L1-SINR indicate beam quality.

When used for beam management, the following reporting parameter combinations are supported in NR:

(1) Channel state information reference signal resource indication (CSI-RS Resource Indicator, CRI) -reference signal received power (Reference Signal Receiving Power, RSRP);

(2)ssb-Index-RSRP；

(3)cri-SINR-r16；

(4)ssb-Index-SINR-r16。

if the higher layer parameter "groupBasedBeamReporting" is set to "disabled status (reporting)", the UE will report nrofReportedRS (RS reporting number) CRI or SSBRI measurements in a single report (report). Otherwise, if the higher layer parameter "groupBasedBeamReporting" is set to "enabled", the UE will report 2 different CRI or SSBRI measurements in a single report (report), where the UE receives CSI-RS and/or SSB resources simultaneously using a single spatial filter or using different spatial filters. The value range of nrofreportedRS is {1,2,3,4}.

NR supports periodic, semi-persistent and aperiodic CSI reporting. For periodic and semi-continuous CSI feedback, the feedback period and feedback time slot offset of the feedback need to be configured in the reporting feedback setting; for aperiodic CSI feedback, the feedback slot offset is indicated by dynamic signaling. CSI reporting content may be fed back either on the physical uplink control channel (Physical Uplink Control Channel, PUCCH) or on (Physical Uplink Shared Channel, PUSCH).

In step 1 of the beam recovery mechanism, the base station configures a (1+.a.ltoreq.2) reference signals for beam failure detection for the UE.

If the UE can still successfully listen to the beam failure detection reference signal after the antenna panel of the UE is switched, the current communication link can still work normally. The UE may report the best beam after switching the antenna panel in a subsequent link quality report, improving the communication quality. Therefore, in this case, no additional enhancement is required.

Otherwise, if the UE cannot sense the beam failure detection reference signal or the detected channel quality is lower than the preset threshold after the antenna panel of the UE is switched, the beam recovery procedure is started according to the existing mechanism, that is: step 2), the UE adopts a non-competitive random access process, and reports the beam failure event and the suggested new candidate beam information to the base station (namely Msg 1) through a pre-allocated PRACH channel; step 3) the base station transmits PDCCH (i.e., msg 2) with the new candidate beam proposed by the UE in beam restoration CORESET.

In step 2), in order to enable the UE to report a new candidate beam, the base station needs to configure B (b≡1) reference signals for beam recovery for the UE, each reference signal corresponds to one candidate beam, and configures a corresponding PRACH channel resource for each candidate beam.

Before the 2 steps of beam recovery, the base station also needs to configure M (M is greater than or equal to 1) radio link interception reference signals for the UE, wherein each reference signal corresponds to one downlink beam direction.

In the prior art, no antenna panel information is associated or indicated in the channel quality information reported by the UE.

As shown in fig. 1, the UE communicates with the base station with the antenna panel 1 all the time, and the beams 1 to 4 are measured on the antenna panel 1; beam 5 is measured on antenna panel 2 to be preferred and the beam quality order is 1>2>3>4>5.

According to different UE capacities and the sensitivity degree of the UE to the power consumption of the UE, the use conditions of the UE on a plurality of antenna panels are different.

A first type of terminal: the UE may receive and transmit signals simultaneously on multiple antenna panels;

and the second type of terminal: the UE may receive signals simultaneously on multiple antenna panels, but may only transmit signals on a single antenna panel;

third class of terminals: at the same time, the UE can only receive and transmit signals on a single antenna panel.

The following 2 major problems need to be solved:

1) For these three types of terminals, whether the UE needs to measure the reference signal quality on the antenna panel 2 and the channel quality of the feedback beam 5?

For the UE measurement and reporting problem, if the third class of terminals always measure and report the reference signal quality on the antenna panel 1 and never on the antenna panel 2, then the base station lacks channel information on the UE side when the UE switches to the antenna panel 2, and the radio link may fail.

Conversely, if the third class of terminal periodically switches to measuring and reporting the reference signal quality on the antenna panel 2, then the base station may choose any beam direction reported by the UE to schedule downlink transmissions for the UE. Considering that the UE can only receive and transmit signals on a single antenna panel at the same time, if the base station selects beam 5 to schedule downlink transmission for the UE, and the signal quality of beam 5 on antenna panel 1 is poor, and the UE has been switched back to operate on antenna panel 1, the UE will not be able to normally receive DL transmission scheduled by the base station, resulting in waste of channel transmission resources.

Aiming at the problems, the embodiment of the application provides a channel quality reporting mechanism, namely, at least for a third class of terminals, network side equipment configures UE to report a standby beam. The UE periodically or aperiodically measures channel quality on a non-optimal antenna panel (referred to as a spare antenna panel), and reports the optimal Y beams to the network side device through spare beam reporting configuration resources, where Y is the number of spare beam reporting in a single report configured by the network side device, Y > =1. The UE does not report the channel quality measurement result on the best antenna panel to the network side device through the spare beam reporting configuration resource.

The base station schedules UE transmissions irrespective of the spare beam reported by the UE.

It should be noted that the embodiments of the present application may also be applied to the first type of terminal and the second type of terminal. Namely, the embodiment of the application does not specifically limit the type of the terminal.

2) How should the base station side select the reference signal set a for beam failure detection and the reference signal set B for beam recovery according to the UE reporting result?

One implementation is: the base station may be configured with M radio link sounding reference signals for the UE, each reference signal corresponding to one downlink beam direction. The M radio link interception reference signals may include all possible downlink beam directions at the base station side; alternatively, the base station selects an appropriate set of downlink beams (e.g., multiple beams near the SSB associated with the UE access) based on the UE location information (based on the initial estimate of the SSB associated with the UE access).

Based on the channel quality measurement result reported by the UE, the base station selects 1-2 beams from the strongest X beams reported by the UE to construct a failure detection reference signal set A. And all M radio link sounding reference signals are selected to construct a reference signal set B for beam recovery.

The problem with the above solution is that the number of beams in the reference signal set B for beam recovery is excessive, resulting in a large overhead of reserved PRACH resources.

In view of the above problems, an embodiment of the present application provides a method for configuring a beam recovery reference signal, that is, at least for a third type of terminal, a network side device configures a spare beam reported by the terminal as a beam recovery reference signal.

In addition, at least for the third class of terminals, the base station needs to pay special attention to the standby beam reported by the UE when configuring the failure detection reference signal. For example, if the UE only reports the first reference signal over the spare beam, the base station will not configure the first beam as a failed detection reference signal.

In the prior art, the transmission resource density of PRACH occalasion corresponding to all beam recovery reference signals is the same. Considering that the success probability of the UE to recover the wireless link in different beam directions is different, different PRACCasion transmission resource densities can be configured for different beam recovery reference signals.

For example, the base station may construct a reference signal set B for beam recovery from selecting all M radio link listening reference signals to ensure robustness of the beam recovery mechanism. However, considering the reserved PRACH resource overhead, the base station may be configured to make the transmission resource density of PRACH occalation corresponding to some beam recovery reference signals greater than that of other reference signals. For example, the transmission resource density of PRACH occalasion corresponding to the standby beam reported by the UE and/or the strongest multiple beams reported by the UE through the normal path is higher than that of other beams, so as to improve the PRACH resource utilization efficiency.

However, the following description describes a New air interface (NR) system for purposes of example, and NR terminology is used in much of the following description, although these techniques are also applicable to applications other than NR system applications, such as the 6th generation (6th Generation,6G) communication system. Referring to fig. 2, an architecture diagram of a wireless communication system according to an embodiment of the present invention is provided. As shown in fig. 2, the wireless communication system may include: a network-side device 21 and a terminal 22, the terminal 22 may be denoted as UE22, and the terminal 22 may communicate (transmit signaling or transmit data) with the network-side device 21.

Referring to fig. 3, an embodiment of the present application provides a channel quality reporting method, where an execution body of the method may be a terminal, and specific steps include: step 301 and step 302.

Step 301: receiving a first reporting configuration (report configuration);

step 302: reporting the channel quality of the first reference signal according to the first reporting configuration;

in an embodiment of the present application, reporting the channel quality of the first reference signal includes one or more of:

(1) An indication of a reference signal, such as SSBRI, and/or CRI, etc.

(2) Channel quality, e.g., L1-RSRP, and/or L1-SINR, where L1-RSRP and L1-SINR may be indicated by absolute values or by differential means.

The differential mode indicates that: if the channel quality of multiple reference signals is reported, the absolute value is reported for the strongest channel quality, while the other channel quality reports the difference between it and the absolute value.

It is understood that the channel quality reporting values are quantized, e.g., in X dB. In some embodiments, the strongest channel quality may be quantized at 1dB intervals, while the differential channel quality may be quantized at 2dB intervals.

Wherein the description of the first reference signal includes one or more of the following combinations:

(1) The channel quality of the first reference signal is the channel quality of the standby reference signal;

(2) The channel quality of the first reference signal is the channel quality of the reference signal which is reported by the terminal through a first antenna panel and is detected on a second antenna panel, and the second antenna panel is different from the first antenna panel;

in one embodiment, the terminal has multiple antenna panels, such as 2 antenna panels, and the terminal can only receive and/or transmit signals on a portion (such as one) of the antenna panels at the same time.

The channel conditions are assumed to be best when the terminal is operating on the first antenna panel, and therefore the terminal is preferentially operating on the first antenna panel. When the first antenna panel is blocked, the terminal will switch rapidly to the other antenna panel. In order to quickly recover from the first antenna shielding event, the terminal may monitor, on other antenna panels other than the first antenna panel, the reference signal sent by the network side device periodically or aperiodically, and report the measurement result to the network side device as the channel quality of the first reference signal. At this time, the terminal may expect that when the antenna panel is switched, the network side device of the service will attempt to recover the communication link of the terminal preferentially according to the channel quality of the first reference signal reported by the terminal.

(3) The first reference signal is associated with transmission resources of a preconfigured first physical random access channel PRACH opportunity;

in this embodiment of the present application, the network side device indicates, in advance, PRACH resources associated with the first type beam recovery reference signal through higher layer signaling (e.g., RRC signaling), and the terminal may autonomously determine that the first reference signal is the first type beam recovery reference signal and is associated with the pre-configured PRACH resources. After the terminal switches the antenna panel, the PRACH may be sent using a pre-configured associated PRACH resource to report a beam failure event and/or suggested new candidate beam (i.e., first reference signal) information.

(4) The terminal expects the first reference signal to be configured as a beam-recovering reference signal.

After reporting the channel quality of the first reference signal, the network side device decides to configure those reference signals as Beam restoration reference signals, which may also be referred to as Candidate beams (Candidate beams). The network side device configures the set of beam-restoration reference signals to the terminal through higher layer signaling (such as RRC and/or MAC CE), and reserves non-contention PRACH resources for each beam-restoration reference signal.

The network side device configures the beam recovery reference signal and its associated PRACH resources to the terminal, for example, through PRACH-ResourceDedicatedBFR IE in RRC signaling.

The terminal only expects the reported first reference signal to be selected by the network side equipment as the beam recovery reference signal. The terminal still receives the higher layer signaling sent by the network side equipment, and determines the beam recovery reference signal and the PRACH resources associated with the beam recovery reference signal.

Optionally, the method may further include: and receiving a high-layer signaling sent by network side equipment, and determining the association relation between the first reference signal and transmission resources of PRACH (physical random access channel) occasions. Determining associated PRACH resources according to the first type beam recovery reference signals and the higher layer signaling; and carrying out PRACH transmission by utilizing the PRACH resources.

Corresponding to the above scheme (4), i.e. the terminal expects the first reference signal to be configured as a beam-recovering reference signal. The terminal only expects the reported first reference signal to be selected by the network side equipment as the beam recovery reference signal. The terminal still receives the higher layer signaling sent by the network side equipment, and determines the beam recovery reference signal and the PRACH resources associated with the beam recovery reference signal.

In an embodiment of the present application, the method may further include: and determining the associated PRACH resources according to the first-type beam recovery reference signals.

Corresponding to the above scheme (3), i.e. the first reference signal is associated with transmission resources of a preconfigured first physical random access channel, PRACH, occasion.

For example, the network side device indicates the PRACH resource (i.e. RACH transmission opportunity) associated with the first type of beam recovery reference signal in advance through higher layer signaling. And after reporting the first reference signal, the terminal autonomously determines that the first reference signal is a first type beam recovery reference signal and is associated with the PRACH resource which is configured in advance.

After the terminal switches the antenna panel, the PRACH is sent by using the pre-configured associated PRACH resource to report the beam failure event and/or the suggested new candidate beam (i.e. the first reference signal) information.

Optionally, the method may further include: receiving an association of at least one set of reference signals with transmission resources of a PRACH occasion, wherein,

or,

In the prior art, the network side device configures the same PRACH resource density for all beam recovery reference signals. In the embodiment of the application, the network side device can configure different PRACH resource densities for different types of beam recovery reference signals.

In one embodiment, the network side device configures the first reference signal (or called a standby reference signal) reported by the terminal and/or the N reference signals with the best channel quality reported by the terminal into beam recovery reference signals (or called candidate beams), and configures (or called reserving) more PRACH resources (i.e. RACH transmission opportunities or called RACH occlusions) for the candidate beams, so as to improve the beam recovery efficiency of the terminal. And the base station configures fewer PRACH transmission opportunities for other candidate beams so as to ensure the robustness of beam recovery of the terminal.

In the embodiment of the present application, the beam recovery reference signal associated with the higher PRACH resource density is referred to as a first type beam recovery reference signal.

In the embodiment of the present application, the first reference signal that the terminal expects to report is configured as a first type of beam-recovering reference signal, which means that the first reference signal that the terminal expects to report is configured as a beam-recovering reference signal (or called a candidate beam), and at least more PRACH resources (i.e. RACH transmission opportunities) are associated compared with one other beam-recovering reference signal.

In this embodiment of the present application, the terminal is not expected to be instructed to perform uplink or downlink transmission by using the first reference signal. For example, if the reference signals reported by the terminal through other reporting configurations except the first reporting configuration are different from the first reference signal (i.e., the terminal does not report the first reference signal through other reporting configurations except the first reporting configuration), the terminal does not expect to be instructed to use the first reference signal for uplink or downlink transmission, and/or the terminal does not expect that the first reference signal is configured as a failure detection reference signal.

Illustratively, a terminal has multiple antenna panels and the terminal can only receive and/or transmit signals on portions of the antenna panels at the same time.

In order to quickly recover from the first antenna panel blocking event, the terminal may periodically or aperiodically monitor the reference signal sent by the network side device on the other antenna panel other than the first antenna panel, and report the measurement result to the network side device through the channel quality of the first reference signal.

The first reference signal is mainly used for the purpose of link quick recovery after antenna panel switching. Since the first reference signal is measured with the inactive or inactive antenna panel, the terminal does not expect the network side device to randomly use the first reference signal to serve the terminal, otherwise, the terminal may not be able to normally receive and/or transmit signals on the active or active antenna panel using the beam direction of the first reference signal.

In the embodiment of the present application, the terminal is not expected to be instructed to perform uplink or downlink transmission by using the first reference signal, and the method may further include: and if the terminal detects that the channel quality of the second reference signal on the second antenna panel is greater than or equal to a second threshold and the channel quality of the second reference signal on the first antenna panel is greater than or equal to a first threshold, the terminal does not report the second reference signal on the first antenna panel through the first reporting configuration, wherein the second antenna panel is different from the first antenna panel.

In this case, the base station does not instruct the terminal to perform uplink or downlink transmission using the first reference signal, that is, there is no other additional condition, that is, there is a pre-existing consensus between the terminal and the base station, so long as the UE reports the reference signal 1 through the first reporting configuration, the base station does not instruct the terminal to perform uplink or downlink transmission using the reference signal 1. As an implementation manner, if the terminal measures that the channel quality of the reference signal 1 is better (for example, greater than or equal to the second threshold) on the inactive or inactive antenna panel (for example, denoted as the second panel), and at the same time, the terminal also measures that the channel quality of the reference signal 1 is better (for example, greater than or equal to the first threshold) on the active or active antenna panel (for example, denoted as the first communication panel), and the terminal wants to receive and/or transmit signals by using the reference signal 1 on the active or active antenna panel, the UE does not report the reference signal 1 through the first reporting configuration; otherwise, if the UE still reports the reference signal 1 through the first reporting configuration, the UE will reasonably consider that the base station will not schedule itself for uplink or downlink transmission with the reference signal 1, which is inconsistent with the UE's will.

Conversely, if the terminal measures that the channel quality of the reference signal 1 is better (e.g., greater than or equal to the second threshold) on the inactive or inactive antenna panel (e.g., denoted as the second panel), and at the same time, the terminal measures that the channel quality of the reference signal 1 is worse (e.g., less than the first threshold) on the active or active antenna panel (e.g., denoted as the first communication panel), the terminal does not wish to receive and/or transmit signals with the reference signal 1 on the active or active antenna panel, and reports the reference signal 1 through the first reporting configuration.

In another embodiment of the present application, the terminal does not expect to be instructed to perform uplink or downlink transmission by using the first reference signal, and the method may further include: if the reference signals reported by the terminal through other reporting configurations except the first reporting configuration are different from the first reference signal, the terminal does not expect to be instructed to use the first reference signal for uplink or downlink transmission, and/or the terminal does not expect that the first reference signal is configured as a failure detection reference signal.

In this case, the base station does not instruct the terminal to have other additional conditions for uplink or downlink transmission using the first reference signal. The terminal does not expect the network side device to provide services for the terminal by using the first reference signal at random. As long as the terminal measures that the channel quality of the reference signal 1 is better at the inactive or inactive antenna panel, the terminal can report the reference signal 1 as a first reference signal to the network side device. The terminal and the base station will combine with other conditions to determine whether to instruct the terminal to perform uplink or downlink transmission by using the reference signal 1.

In this embodiment of the present application, if the terminal has not reported the first reference signal through the reporting configuration other than the first reporting configuration (if the reference signal reported by the terminal through the reporting configuration other than the first reporting configuration is different from the first reference signal), the terminal does not expect to be instructed to use the first reference signal for uplink or downlink transmission.

That is, there is a consensus between the terminal and the network side device, if the terminal has reported the reference signal 1 through other reporting configurations except the first reporting configuration, which indicates that the reference signal 1 is active or the beam direction with better channel quality on the activated antenna panel, the network side device may select the reference signal 1 for uplink or downlink transmission of the terminal; otherwise, if the terminal does not pass the other reporting configuration reference signal 1 except the first reporting configuration, that is, indicates that the reference signal 1 is not active or the beam direction with better channel quality on the activated antenna panel, the network side device will not select the reference signal 1 for uplink and downlink transmission of the terminal, that is, the terminal does not expect to be instructed to use the reported first reference signal uplink or downlink transmission.

In an embodiment of the present application, the method may further include:

and reporting the antenna panel capability of the terminal.

Optionally, the antenna panel capability includes at least one of:

(1) The number of antenna panels;

(2) Whether or not reception is possible on all antenna panels simultaneously;

(3) Whether or not to transmit simultaneously on all antenna panels;

(4) The number of antenna panels that cannot receive data simultaneously;

(5) The number of antenna panels that cannot transmit data simultaneously;

(6) The number of antenna panel groups which cannot receive data simultaneously, wherein each antenna panel group at least comprises one antenna panel;

(7) And the number of antenna panel groups which cannot transmit data simultaneously, wherein each antenna panel group at least comprises one antenna panel.

For example, the terminal has 4 antenna panels.

Example 1: the terminal can simultaneously receive and transmit data on the 4 antenna panels;

example 2: the terminal can only receive and transmit data on a single antenna panel at the same time;

example 3: the antenna panel 1 and the antenna panel 2 form an antenna panel group 1, the antenna panel 3 and the antenna panel 4 form an antenna panel group 2, and in each antenna panel group, the terminal can simultaneously receive and transmit data; in different antenna panel groups, the terminal cannot receive and transmit data at the same time, namely, the UE can only receive and transmit data in a single antenna panel group at the same time;

For example 1, the network-side device does not need to configure the first reporting resource for the terminal because the terminal is not required to report the channel quality of the first reference signal (i.e., the standby reference signal).

Whereas for examples 2 and 3, the base station needs to configure the first reporting resource for the terminal for reporting the channel quality of the first reference signal (i.e., the standby reference signal).

In particular, the network side device may determine, according to the number of antenna panels that the terminal cannot simultaneously perform data transmission and/or reception, or the network side device may determine, according to the number of antenna panel groups that the terminal cannot simultaneously perform data transmission and/or reception, the number of first reference signals (i.e. standby reference signals) that need to be reported by the terminal.

If the network side equipment determines that the number of antenna panels which can not receive and/or transmit data at the same time is N, the network side equipment configures the terminal to report N first reference signals, wherein N is greater than or equal to 1.

For example, if the network side device determines that the number of antenna panels that the terminal cannot simultaneously perform data reception and/or transmission is N1, the network side device may configure the terminal to report N1 first reference signals.

Similarly, if the network side device determines that the number of antenna panel groups that the UE cannot simultaneously perform data reception and/or transmission is N2, the network side device may configure the terminal to report N2 first reference signals.

In the embodiment of the present application, the first reporting configuration includes: first indication information;

the first indication information indicates any one of:

mode 1: the first reporting configuration is used for reporting the channel quality of the first reference signal;

the manner in which the first reporting configuration is used to determine the transmission resource of the terminal reporting the channel quality may be an existing manner, and in this embodiment of the present application, the first reporting configuration may be determined by using the first indication information to only use the first reporting configuration to report the channel quality of the first reference signal (i.e. the standby reference signal) by the terminal.

Mode 2: the first indication information indicates that part of resources in the first reporting configuration are used for reporting channel quality of the first reference signal.

The difference from mode 1 is that the resources in the first reporting configuration can carry both the channel quality of the first reference signal and the channel quality of the non-first reference signal (other reference signals).

Referring to fig. 4, in an embodiment, the network side device indicates, through the first indication information, a channel quality of the first reference signal carried by the reporting resource of the usage portion.

The RRC reporting configuration signaling in the existing protocol is given below. The reportConfigType configures reported time domain resources from periodic (carried by periodic PUCCH), semipersistent on PUCCH (carried by semi-persistent PUCCH), semipersistent on PUSCH (carried by semi-persistent PUSCH), and apidic (carried by aperiodic PUSCH).

For periodic, semiPersistentOnPUCCH, semiPersistentOnPUSCH, a period (Periodicity) and an Offset (Offset) of the time domain transmission resource are further configured.

nrofreporteddrs is used to indicate the channel quality of reporting several RSs in a single reporting resource.

In an embodiment of mode 2, the first indication information includes at least a first parameter M, which is used to indicate that a kth reporting resource is selected from every M reporting resources to report the channel quality of the first reference signal, where k is a preset constant.

For example, k=1, which indicates the channel quality of the first reference signal of the 1 st reporting resource selected from every M reporting resources. Or may also be expressed as:

the period of the reporting resource of the first reference signal is as follows: m x periodic; the timing Offset is Offset, where the Periodicity and Offset are determined from existing configurations.

In the existing configuration, nrofreporteddrs is used to indicate channel quality of reporting several RSs in a single reporting resource, and the value range of nrofreporteddrs is {1,2,3,4}. If nrofreportedss is greater than 1, the channel quality of the first reference signal reported at a portion of the RS locations may be selected according to the following rule. The rule includes:

Option 1) if the channel quality of at most m first reference signals needs to be reported, the UE selects to report the channel quality of the first reference signals in the 1 st to m (RS) in a given reporting resource; or,

option 2) reporting the channel quality of the first reference signal in the number of RS reports (nrofreportedds) -m+1 to nrofreportedds RS.

In option 2), if m=nrofreportedsr, the absolute value of the channel quality (e.g., RSRP or SINR) of the strongest first reference signal is reported in the first RS position, while the relative values of the other first reference signals with respect to the strongest channel quality are reported in the other RS positions.

If m < nrofreportedsr, its relative value with respect to the strongest channel quality reported at the first RS position is reported for all first reference signals.

In another embodiment of mode 2, the first indication information includes at least a first parameter M and a sequence number n, where k is a preset constant, for indicating channel quality of reporting the first reference signal at an nth RS position where a kth reporting resource is selected from every M reporting resources.

If nrofreportedss is greater than 1, the channel quality of the first reference signal reported at a portion of the RS locations may be selected according to the following rule. The rule includes:

Option 1): if the channel quality of at most m first reference signals needs to be reported, the UE selects to report the channel quality of the first reference signals in the n-n+m RS in given reporting resources; or,

option 2): the channel quality of the first reference signal is reported in the nrofreportedds-n-m+1 to nrofreportedds-n RSs.

In option 1) or option 2), if the reporting position range of the first reference signal includes the first RS position, the absolute value of the channel quality (such as RSRP or SINR) of the strongest first reference signal is reported at the first RS position, and the relative values of the other first reference signals with respect to the strongest channel quality are reported at the other RS positions.

Otherwise, if the reporting position range of the first reference signal does not include the first RS position, reporting the relative value of the first reference signal with respect to the strongest channel quality reported by the first RS position for all the first reference signals.

It can be appreciated that in modes 1 and 2, the terminal may choose not to report the channel quality of any first reference signal. For example, the terminal is not expected to be instructed to perform uplink and downlink transmission by using the reported first reference signal. As an implementation manner, if the terminal measures that the channel quality of the reference signal 1 is better on the inactive or inactive antenna panel, and at the same time, the terminal also measures that the channel quality of the reference signal 1 is better on the active or active antenna panel, and the terminal expects to receive and/or send signals by using the reference signal 1 on the active or active antenna panel, the terminal will not report the reference signal 1 as the first reference signal to the base station.

In addition, the network side equipment is supported to configure the spare beam reported by the terminal and/or the transmission resource density of the PRACCA corresponding to the strongest multiple beams reported by the terminal through the normal path to be higher than that of other beams, so that the PRACH resource utilization efficiency is improved.

In addition, the network side device may configure the spare beam reported by the terminal and/or the transmission resource density of PRACH occalasion corresponding to the strongest multiple beams reported by the terminal through the normal path, which is higher than other beams, so as to improve the PRACH resource utilization efficiency.
