Description

Beam management method and device
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a beam management method and apparatus.
Background
In the new wireless (NR) technology system of 5G, massive multi-antenna (massive MIMO) technology is one of the most important technical characteristics, especially for a high-frequency band (i.e. millimeter wave band) transmission channel, due to the large transmission link loss, the coverage of a base station signal can be improved by using a high-gain and adjustable shaped beam, and the interference to the periphery can be reduced by using a narrower beam. In order to achieve the above functions, the Base Station (BS) needs to implement more accurate beamforming, so that beam management and beam control are critical to massive MIMO.
In addition, since 5G supports a larger bandwidth, a higher throughput, and more complex traffic and more complex processing techniques matched thereto, power saving design of a terminal, such as a User Equipment (UE), becomes necessary. The power-saving optimization design can save the power consumption of the terminal and prolong the service life of the battery, thereby improving the experience of users, and being very important for 5G industrialization. The discontinuous reception (Discontinuous Reception, DRX) mechanism used in the 5G system can enable the terminal to monitor discontinuous downlink channels, so that the effect of reducing the power consumption of the terminal is achieved. If the base station does not have a pre-configured measurement Reference Signal (RS) and channel state information (Channel State Information, CSI) reporting resource, neither the base station nor the terminal can perform beam (beam) information update during discontinuous reception (Opportunity for DRX).

Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In the 5G NR system, beam management mainly includes several procedures such as beam determination, beam measurement and reporting, beam scanning, beam indication, and beam recovery.
Beam determination, i.e. which set of transmit/receive beams is selected for the base station BS and the user UE for transmission of control information and data transmission. For each transmit beam, the UE may perform a series of receive beam scans to find the optimal transmit-receive beam pair. The UE does not report the optimal receive beam to the BS but rather keeps it down for receiving data.
The beam measurement and reporting process refers to that only a measured value of a Reference Signal (RS) resource needs to be reported for each transmitting beam, and no receiving beam needs to be reported. The BS may perform beam selection according to the reported Reference Signal Received Power (RSRP), reference Signal Received Quality (RSRQ), or channel state information CSI measurement results. The beam measurement and reporting may be based on synchronization signal blocks (Synchronization Signal Block, SSB) or CSI reference signals (CSI-RS). The beam reporting may be done on a Physical Uplink Control Channel (PUCCH) or a physical uplink shared channel PUSCH, and the reporting format and procedure are indicated by CSI reporting.
For the beam indication procedure, the manner in which different channels are indicated is different.
For downlink beam management, when a UE initially accesses, the UE obtains an initial transmit beam of the base station by scanning SSBs. After the UE is accessed to the cell, the BS configures beam measurement and beam information reporting configuration for the UE, and the UE performs measurement according to the reference signal configured by the base station, such as SSB or CSI-RS, and performs measurement reporting according to the beam information reporting configuration. The reported measurement may be RSRP, RSRQ or CSI. The BS may perform beam selection according to the reported RSRP, RSRQ, or CSI measurement results. Beam reporting may be done on PUCCH or PUSCH. The BS may send an updated beam indication to the UE, where the beam indication of the PDSCH may be a transmission configuration indication (Transmission Configuration Indication, TCI) in the DCI, or may be a TCI state (state) in a radio resource control (Radio Resource Control, RRC) configuration control resource set (CORESET); the beam indication of the PDCCH is TCI state in RRC configuration CORESET, for which activation/deactivation by a medium access control element (MAC CE) is required.
For uplink beam management, if the UE supports uplink and downlink beam consistency, the UE's transmit beam is consistent with the downlink UE's receive beam. In addition, the BS may indicate an optimal uplink transmission beam to the UE by measuring Sounding Reference Signal (SRS) resources. The PUSCH transmission beam indication may be a beam indication of SRS, or may be a spatial relationship with PUCCH indicated in DCI, and the PUCCH transmission beam indication may be RRC configuration, or RRC configuration and MAC CE combined.
In addition to the above functions, to avoid link connection failure caused by blocking or high link loss in the signal transmission process, the UE also monitors the PDCCH beam, and if the beam detection fails, a beam failure report and a new beam need to be reported. After receiving the beam failure report, the BS uses a new beam to transmit PDCCH.
In the 5G NR system, the current working states of UEs are divided into three types: the first two UEs need to monitor paging signals, namely RRC IDLE (rrc_idle), RRC Inactive (rrc_active) and RRC Connected (rrc_connected), when the UE receives the paging signals, it indicates that the network side has data to send, and the UE needs to enter into the rrc_connected state to receive downlink data. And in the rrc_connected state, the UE needs to monitor the downlink control channel PDCCH continuously to acquire the transmission information of the downlink PDSCH. Whereas packet-based data streams are typically bursty, with data transmission for a period of time, but no data transmission for a longer period of time next, continuous monitoring of the PDCCH necessarily results in rapid power consumption by the UE. Therefore, when there is no data transmission, power consumption can be reduced by stopping receiving the PDCCH (at this time, stopping PDCCH blind detection). Therefore, the 3GPP is designed to achieve the power saving purpose through the DRX (Discontinuous Reception discontinuous reception) mechanism, as shown in fig. 1. During the DRX cycle, the UE monitors the PDCCH only during the DRX active (On duration) period, and during "Opportunity for DRX", i.e., the DRX inactive period (DRX off), the UE does not receive the PDCCH to reduce power consumption, i.e., enters a sleep mode.
When the UE configures DRX, in Opportunity for DRX, if no preconfigured periodic or semi-persistent reference signal is used for beam (beam) measurement or reporting, when the position of the UE changes or encounters a blocking or link quality degradation, the UE cannot perform beam measurement reporting and subsequent beam update; if there is a pre-configured periodic or semi-persistent reference signal, the UE may make CSI measurements, but if the UE is not pre-configured at the CSI reporting time, no CSI reporting and subsequent beam updates are made. The following are listed by way of example:
if the BS's transmit Beam changes, there is no pre-RS configuration (excluding the pre-configured periodic CSI-RS case) at Opportunity for DRX, the BS can only indicate transmit Beam to the UE based on the previous UE reporting results, and the UE performs receive Beam selection based on a non-updated transmit Beam, resulting in a mismatch between the actual Channel State Information (CSI) and the transmit-receive Beam pair, which can affect data reception.
If the BS's transmitted Beam changes, only aperiodic reporting is configured if there are preconfigured periodic CSI-RS resources. The UE performs the sending beam scanning based on the pre-configured reporting configuration before, and after the optimal sending beam and the optimal receiving beam are found, the UE does not have reporting opportunity when the UE is in a Opportunity for DRX state because the non-periodic CSI reporting is only reported once, and the base station cannot obtain updated sending beam information;
If the BS's transmitted beam is unchanged, but the received beam is changed due to the change of the UE's position, and there is no RS configuration (excluding the case of the periodically configured CSI-RS), the UE cannot perform CSI measurement, i.e. cannot obtain the optimal received beam, and can only perform reception based on the previously stored beam, which may cause beam failure (failure).
The embodiment of the application provides a beam management method and device, which are used for realizing the beam information related processing under the condition that a terminal is in a power saving state. Namely, the embodiment of the application mainly aims at the existing DRX transmission mechanism and beam management mechanism, and provides a new beam management method and device, so that accurate beam information can be obtained while the terminal is in a power-saving state.
The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

Various embodiments of the present application are described in detail below with reference to the drawings attached hereto. It should be noted that, the display sequence of the embodiments of the present application only represents the sequence of the embodiments, and does not represent the advantages or disadvantages of the technical solutions provided by the embodiments.
When DRX is introduced, the number of antennas for low frequency communication is limited, beam is relatively wide, and beam selection is not involved, or to a certain extent, a transmitting-receiving beam pair between a base station and a user is relatively stable. However, when the number of antennas increases, the beam becomes narrow, and the change of the transmitting and receiving beam between the base station and the user is relatively fast, the original DRX mechanism cannot meet the requirement, so that the beam management needs to be performed in the DRX inactive state. Therefore, the embodiment of the application proposes that the network side sends the power saving signal to trigger the terminal to carry out beam management under the DRX inactive state. The power saving signal may be carried in a trigger RS mentioned below, or may be configured through RRC signaling.
According to the technical scheme provided by the embodiment of the application, the triggering RS is introduced, so that the problem that beam information cannot be updated and indicated in the Opportunity for DRX period is solved. The BS sends a trigger RS to the UE, which may be used to indicate configuration information of the measurement RS, beam reporting configuration information (which may also be referred to as CSI reporting configuration information), send a beam information indication, and whether to deactivate periodic or semi-persistent beam measurements.
Here, the trigger RS may be a new RS, for example, a power saving signal (power saving signal), or may be a signaling such as DCI, MAC CE, or RRC signaling. The triggering RS may, for example, specifically carry one or a combination of the following information:
1. an identification for indicating whether there is a measurement RS, for example: 0 denotes no measurement RS,1 denotes a measurement RS;
the measurement RS mentioned in the embodiment of the present application may be an existing RS or a newly defined RS.
2. Measuring RS information, including periodic, time-frequency resource allocation, where periodic refers to measuring RS being periodic, semi-persistent, or aperiodic; the time-frequency resource allocation refers to measuring the time-domain resource allocation and the frequency-domain resource allocation of the RS, namely measuring the time-domain position and the frequency-domain position of the RS;
both of the former two pieces of information belong to configuration information of the measurement RS.
3. Beam reports configuration information, including, for example:
a. reporting types, for example: periodic, non-persistent or non-periodic reporting of Beam information;
b. the reporting period of the Beam information is mainly aimed at the periodic/non-continuous reporting type, and the reporting period of the Beam information is indicated;
c. the reporting time of the Beam information, for example: reporting period, offset (offset), etc. of the Beam information;
d. Beam measurement types, for example: RSRP or RSRQ or CSI or others.
e. The reported number of beams or clusters was measured.
4. Beam information indicates, for example: a transmission configuration indication (Transmission configuration indication) of the Beam information.
The Beam information indication may be information related to the selected Beam after the base station performs Beam selection based on the Beam related measurement quantity reported by the terminal; in addition, the base station may not perform Beam selection based on the Beam related measurement quantity reported by the terminal, and the base station may autonomously select a Beam and notify the terminal of the Beam selection result by carrying the Beam information indication in the trigger RS.
The measured RS may be a newly introduced RS or an existing RS, for example, CSI-RS.
If the identification of the measuring RS is 1, the Beam information is the Beam information of the measuring RS;
if the identity of the measurement RS is 0, the Beam information transmits Beam information for the BS.
The configuration information reported for Beam measurement may be a parameter set preconfigured through RRC signaling, and then index indication is performed through DCI parameter set, for example, periodic or semi-persistent reporting, or consistent with the previous configuration; or may be carried by triggering RS, such as aperiodic measurement reporting.
After receiving the trigger RS, the UE carries out corresponding Beam measurement on different measurement RSs based on configuration information and Beam information indication of the measurement RS carried by the trigger RS to obtain Beam-related measurement quantity; and reporting Beam information (namely the Beam related measurement quantity) corresponding to the number of the beams or the number of the groups according to the Beam measurement reporting configuration information, wherein the Beam information is the measurement quantity required in the Beam measurement reporting configuration, and the BS performs Beam selection based on the Beam information reported by the UE. Wherein,,
the Beam measurements, for example: based on the measurement RS, corresponding beam measurement is carried out, and the measured beam related information is information such as RSRP, RSRQ, CSI and the like;
the Beam information is reported, for example: the UE reports the measurement information of the number which is optimally measured to the base station according to the number of reported beams specified in the report information configured by the base station;
the Beam information selection, for example: the BS selects, for example, the best Beam to send according to the Beam information reported by the UE.
If the BS does not require the UE to make Beam reports again, but has configured periodic or semi-persistent measurement reports, the BS deactivates periodic Beam measurements by sending a trigger RS.
Embodiment one:
the BS does not have a pre-configured periodic/non-persistent RS, e.g., periodic/non-persistent CSI-RS. A trigger RS is introduced to trigger the UE to receive an RS for beam measurement, where the trigger RS may be a new RS, such as a power saving signal (power saving signal), or may be a signaling such as DCI, MAC CE or RRC signaling. The present embodiment exemplifies a DCI-based power saving signal (DCI-based power saving signal).
The first step: when the BS determines that the current channel state of the UE changes faster, the BS may change the best beam sent by the BS, and since the UE is in Opportunity for DRX state, i.e. in the DRX inactive period, the BS does not have a preconfigured periodic/discontinuous RS, and the UE cannot measure and report the CSI of the current channel.
And a second step of: the BS sends a triggering RS and a measuring RS to the UE, wherein the content carried by the triggering RS comprises the following information:
1. an identification for indicating whether there is a measurement RS, for example: 0 denotes no measurement RS,1 denotes a measurement RS;
2. measuring RS information, including periodic, time-frequency resource allocation, where periodic refers to measuring RS being periodic, semi-persistent, or aperiodic; the time-frequency resource allocation refers to measuring the time-domain resource allocation and the frequency-domain resource allocation of the RS;
3. The Beam measurement report configuration index or Beam measurement report configuration information, wherein the Beam measurement report configuration information comprises:
reporting types, for example: periodic, non-persistent or non-periodic reporting of Beam information;
the reporting period of the Beam information is mainly aimed at the periodic/non-continuous reporting type, and the reporting period of the Beam information is indicated;
the reporting time of the Beam information, for example: reporting period, offset (offset), etc. of the Beam information;
beam measurement types, for example: RSRP or RSRQ or CSI or others;
the reported number of beams or clusters was measured.
4. Beam information indicates, for example: a transmission configuration indication (Transmission configuration indication) of the Beam information.
If the measurement RS is periodic or semi-persistent, and the reporting type is also periodic or semi-persistent, i.e., the BS needs to periodically obtain the beam information of the UE.
If the measurement RS is aperiodic and the reporting type is also aperiodic, the BS only needs to obtain the beam information of the UE at the moment.
If the measurement RS is periodic or semi-persistent and the reporting type is non-periodic, the BS only needs to obtain the UE's instantaneous beam information.
If the identification of the measuring RS is 1, the Beam information is the Beam information of the measuring RS; if the identity of the measurement RS is 0, the Beam information transmits Beam information for the BS.
The configuration information reported by Beam measurement can be a parameter set pre-configured by RRC signaling, and index indication is performed on the parameter set by DCI, for example, periodic or semi-continuous reporting or consistent with the configuration reported by previous measurement; or may be carried by triggering RS, such as aperiodic measurement reporting.
And a third step of: when the UE receives the trigger RS, beam measurement is performed on the designated measurement RS. If the trigger RS indicates that the beam report is periodic or semi-continuous, the UE may perform beam measurement based on the periodic or non-continuous measurement RS after receiving the trigger RS until receiving a deactivation command of the measurement report, for example, the deactivation command of the measurement report is carried by the MAC CE, and stop the beam information report. If the triggering RS indicates that the beam report is non-periodic, the UE only needs to report the beam measurement information once after receiving the triggering RS.
The RS used for Beam measurement may be a newly introduced RS or an existing RS, e.g., CSI-RS. After the UE obtains the relevant beam information, where the beam information may be RSRP, RSRQ or CSI received by the terminal UE, and reporting the beam information at the reporting time and the resource location indicated on the trigger RS.
Fourth step: the BS updates the sending beam of the UE based on the recently reported beam information of the UE and sends a sending beam indication thereof to the UE. The BS may transmit to the UE through DCI, PDCCH, or a new RS, for example power saving signal. Taking DCI-based power saving signal in this embodiment as an example, when the identifier of the measurement RS is 0, the beam information is the transmitted beam information of the BS.
Embodiment two:
the BS has pre-configured periodic/non-persistent reference signals, such as periodic/non-persistent CSI-RS, or SSB, but has not configured periodic/non-persistent CSI reporting. And introducing a triggering RS for triggering the UE to feed back the current beam information. The trigger RS may be a new RS, for example power saving signal, or may be a new DCI, MAC CE or RRC signaling, which is exemplified by DCI-based power saving signal in this embodiment.
The first step: when the BS judges that the current channel state of the UE changes quickly, the optimal sending beam of the BS may change, the UE is in a DRX-off state, the UE temporarily has no scheduling information, and the UE cannot perform CSI feedback of the current channel.
And a second step of: the BS sends a triggering RS to the UE, wherein the content carried by the triggering RS comprises the following information:
1. an identification for indicating whether there is a measurement RS, for example: 0 denotes no measurement RS,1 denotes a measurement RS;
2. Measuring RS information, including periodic information and time-frequency resource information; here, periodic means that the measurement RS is periodic, semi-persistent, or aperiodic; the time-frequency resource refers to time domain resource allocation and frequency domain resource allocation of the measured RS;
3. beam measurement reporting configuration index or Beam measurement reporting configuration information, wherein the measurement reporting configuration information comprises:
reporting types, for example: periodic, non-persistent or non-periodic reporting of Beam information;
the reporting period of the Beam information is mainly aimed at the periodic/non-continuous reporting type, and the reporting period of the Beam information is indicated;
the reporting time of the Beam information, for example: reporting period, offset (offset), etc. of the Beam information;
beam measurement types, for example: RSRP or RSRQ or CSI or others;
the reported number of beams or clusters was measured.
4. Beam information indicates, for example: a transmission configuration indication (Transmission configuration indication) of the Beam information.
If the reporting type is also periodic or semi-persistent, i.e., the BS needs to periodically obtain the beam information of the UE.
If the reporting type is aperiodic, i.e., the BS only needs to obtain the UE's instantaneous beam information.
Since the BS has preconfigured the periodic/non-persistent reference signal, here, the identity of the measurement RS is 0, and the measurement RS information and the Beam information are default.
The configuration information reported by Beam measurement can be a parameter set pre-configured by RRC signaling, and index indication is performed on the parameter set by DCI, for example, periodic or semi-continuous reporting or consistent with the configuration reported by previous measurement; or may be carried by triggering RS, such as aperiodic measurement reporting.
And a third step of: when the UE receives the trigger RS, if the measurement RS information and the Beam information are found to be default, the UE performs measurement feedback based on the preconfigured RS before the reporting time; if the pre-configured RS does not exist before the reporting time, the UE feeds back based on the stored beam information. If the trigger RS indicates that the beam report is periodic or semi-persistent, the UE will stop the beam information report after receiving the trigger RS, based on the periodic or non-persistent report measurement value, until receiving a deactivation command of the measurement report, for example, carried by the MAC CE. If the trigger RS indicates that the beam report is non-periodic, the UE only needs to report the measurement information before the measurement report time after receiving the trigger RS.
The RS used for Beam measurement may be a newly introduced RS or an existing RS, such as CSI-RS or SSB. After the UE obtains the relevant beam information, where the beam information may be RSRP, RSRQ or CSI received by the terminal, and reporting the beam information at the reporting time and the resource location indicated on the trigger RS.
Fourth step: the BS updates the sending beam of the UE based on the recently reported beam information of the UE and sends a sending beam indication thereof to the UE. The BS may transmit to the UE through DCI, PDCCH, or a new RS, for example power saving signal. Taking DCI-based power saving signal in this embodiment as an example, when the identifier of the measurement RS is 0, the beam information is the transmitted beam information of the BS.
Embodiment III:
the BS does not have a pre-configured periodic/non-persistent RS, e.g., periodic/non-persistent CSI-RS. When the position of the UE is shifted, the information of the receiving and transmitting beam stored by the UE cannot be updated, and the UE cannot receive signals on the better receiving beam. And introducing a triggering RS for triggering the UE to update the information of the receiving beam. The trigger RS may be a new RS, for example power saving signal, or may be a new DCI, MAC CE or RRC signaling, which is exemplified by DCI-based power saving signal in this embodiment.
The first step: when the BS judges that the current channel state of the UE is poor, the BS does not change the sending beam, and no reference signal is provided for the UE to measure and update the CSI of the current channel in DRX-off.
And a second step of: the BS sends a triggering RS and a measuring RS to the UE, wherein the content carried by the triggering RS comprises the following information:
1. Whether there is an identity of the measurement RS, for example: 0 denotes no measurement RS,1 denotes a measurement RS;
2. measuring RS information, including periodic, time-frequency resource allocation, where periodic refers to measuring RS being periodic, semi-persistent, or aperiodic; the time-frequency resource allocation refers to measuring the time-domain resource allocation and the frequency-domain resource allocation of the RS;
3. the Beam measurement report configuration index or Beam measurement report configuration information, wherein the measurement report configuration information comprises:
reporting types, for example: periodic, non-persistent or non-periodic reporting of Beam information;
the reporting period of the Beam information is mainly aimed at the periodic/non-continuous reporting type, and the reporting period of the Beam information is indicated;
the reporting time of the Beam information, for example: reporting period, offset (offset), etc. of the Beam information;
beam measurement types, for example: RSRP or RSRQ or CSI or others;
the reported number of beams or clusters was measured.
4. Beam information indicates, for example: a transmission configuration indication (Transmission configuration indication) of the Beam information.
If the measurement RS is periodic or semi-persistent, i.e., the UE may periodically perform a reception beam information update based on the measurement RS.
If the measurement RS is aperiodic, i.e. the UE only needs to update the instantaneous beam information.
In this case, the reporting type and the reporting time of the beam information may be default without reporting the beam information.
If the identification of the measuring RS is 1, the Beam information is the Beam information of the measuring RS; if the identity of the measurement RS is 0, the Beam information is the BS transmitting Beam information, which may be default.
The configuration information reported by Beam measurement can be a parameter set pre-configured by RRC signaling, and index indication is performed on the parameter set by DCI, for example, periodic or semi-continuous reporting or consistent with the configuration reported by previous measurement; or may be carried by triggering RS, such as aperiodic measurement reporting.
And a third step of: when the UE receives the trigger RS, beam measurement is performed on the designated measurement RS. If the measurement RS is periodic or semi-persistent, the UE will update the periodic or semi-persistent reception beam information based on the periodic or non-persistent measurement RS after receiving the trigger RS, until receiving a deactivation command reported by the measurement, for example, the deactivation command may be carried by the MAC CE, or may be carried by the trigger RS, for example, where the identity of the measurement RS is 0 and the other information fields are default. If the measurement RS indicated by the trigger RS is aperiodic, the UE only needs to update the information of the received beam once after receiving the trigger RS.
The RS used for Beam measurement may be a newly introduced RS or an existing RS, e.g., CSI-RS. After the UE obtains the relevant beam information, the beam information may be RSRP, RSRQ, or CSI received by the UE.
