Description

[0001] This application is a divisional application of the original application with application number 201710184664.1, application date March 24, 2017, entitled "Beam recovery processing and beam recovery method, base station and terminal". Technical Field

[0002] This invention relates to the field of communications, and more specifically, to a beam recovery processing and method, a base station, and a terminal. Background Technology

[0003] In wireless communication systems using relevant technologies, both the transmitting and receiving ends typically employ multiple antennas (for both transmission and reception) to achieve higher data rates. One principle of multi-antenna technology is to utilize channel characteristics through beamforming to create transmission and reception patterns that match those characteristics. This highly targeted signal radiation effectively improves system performance, achieving significant performance gains without increasing bandwidth or power. It is a promising technology widely used in current systems. Beamforming techniques, such as... Figure 1 As shown, Figure 1 It is based on a schematic diagram of beamforming technology in related technologies.

[0004] Beamforming is achieved through precoding, which can form beams in the feature space or in the physical space. Precoding can include two parts: baseband precoding and radio frequency (RF) precoding, corresponding to baseband beams and RF beams, respectively. Baseband processing mainly operates on the RF path, while RF processing mainly operates on the elements of the RF path; the former is completed in the baseband, and the latter in the RF. The beams mentioned in this invention can be baseband, RF, or a combination of both.

[0005] When deploying massive MIMO antennas at the base station, considering the high dimensionality of the channel and the simultaneous presence of radio frequency precoding and baseband precoding, the following methods are generally used to implement measurement feedback and transmission in a MIMO system:

[0006] Beam information measurement feedback (beam training):

[0007] Step 1: The base station sends beam pilot signals in different directions and notifies the receiving end of the configuration information.

[0008] Step 2: The terminal measures the reception quality of these beam pilots and selects the pilots with better quality to feed back to the base station;

[0009] Step 3: The base station uses the precoding corresponding to these pilots to transmit data.

[0010] Here, the base station continues to send a narrower beam within the coverage area of ​​the selected beam, and the terminal aligns and selects it. This allows for finer beam selection, and the base station obtains more accurate beam direction information through feedback from the terminal. This training step can be performed multiple times.

[0011] Alternatively, the base station can also send some pilot signals based on the beam reported by the terminal to measure the interference between beams or the optimal weighted combining parameters between beams. These weights are generally performed on the baseband, which can obtain a greater combining gain, and can actually be regarded as a more accurate beam (within the characteristic space).

[0012] After obtaining the above beam selection information, the base station can use these beams for downlink transmission. If further channel state information (CSI) can be obtained, the transmission performance can be improved more effectively. Both CSI information and beam information can be obtained by measuring the measurement pilot.

[0013] After acquiring beam information and CSI information, the base station can use them for downlink transmission. As operating frequencies increase, beams are used for transmission on control and data channels to enhance coverage. Beam transmission offers high transmission efficiency, but its robustness is not very good. Due to the narrow beam, issues such as motion, terminal rotation, propagation path obstruction, or blockage often lead to a degradation in the quality of the serving beam, resulting in communication failures. Since the control channel also requires beam transmission, if the base station cannot quickly detect beam failure and cannot send control signaling, both uplink and downlink transmissions cannot be initiated, causing the entire link to collapse. On the one hand, the terminal may not realize that the downlink link has been broken; on the other hand, even if the terminal notices that some uplink requests are not being responded to and realizes that the link is faulty, the terminal can only re-initiate the access process, wasting a lot of system resources and resulting in a poor user experience.

[0014] In related technologies, when beam quality deteriorates significantly, base stations lack effective mechanisms to quickly detect beam problems and find more suitable beams. Even if the base station could detect the problem quickly, it would require very frequent transmission of measurement pilots and periodic reporting of beam information. This places a significant overhead burden on both downlink and uplink, degrading system performance and impacting forward compatibility.

[0015] When beam quality deteriorates significantly in related technologies, base stations lack a good mechanism to quickly detect beam problems and find more suitable beams, and there is currently no effective solution. Summary of the Invention

[0157] The method provided in the preferred embodiments of the present invention has the above-mentioned features. The following are several specific embodiments of the preferred embodiments of the present invention. The technical solutions of this application can be understood in conjunction with the following specific embodiments. Specific Implementation Example 1:

[0159] Step 101: The base station configures uplink resources to send beam recovery information to the terminal;

[0160] The uplink resources configured by the base station can be at some specified time-frequency locations. Since beam recovery information may be transmitted, the base station will perform detection at the corresponding locations. When the triggering conditions related to beam recovery are met, the terminal can transmit beam recovery information at these candidate time-frequency locations.

[0161] Step 201: The terminal determines the first set of configuration information used for beam quality monitoring;

[0162] This configuration may optionally include reference pilot information for beam quality monitoring. The terminal can determine this based on the base station configuration or according to some agreed-upon rules.

[0163] Step 301: The terminal determines a second set of configuration information for beam selection;

[0164] This configuration may optionally include the configuration of reference signals for beam selection. The terminal can determine this based on the base station's configuration or according to agreed-upon rules. It may also include the number of beams to select, constraints, etc.

[0165] Step 401: The terminal determines the third set of configuration information used for beam recovery information reporting;

[0166] This configuration is used to determine the reported content, reporting format, resources for the reported content, and the method of sending the reported content.

[0167] Step 501: The terminal determines the fourth set of configuration information used to determine beam selection and / or report;

[0168] This configuration may optionally include some criteria and parameters for determining whether beam selection and / or beam reporting steps are required.

[0169] Step 601: The terminal measures the downlink beam quality according to the first configuration information set;

[0170] Alternatively, it can be determined by judging the received power or by judging the channel loss corresponding to the beam.

[0171] Step 701: The terminal determines whether the beam selection and / or reporting trigger conditions are met based on the fourth configuration information set.

[0172] Some alternative methods will be described in detail in the following specific embodiments.

[0173] Step 801: When the beam selection trigger condition is met, the terminal performs beam selection according to the second configuration information;

[0174] After determining the beam selection range, beam selection can be performed, selecting the available beams.

[0175] Step 901: When the reported triggering condition is met, the terminal reports beam recovery information according to the third configuration information;

[0176] Optionally, the beam recovery information includes the index information of the selected beam and / or UE ID information; this information can be carried through explicit signaling content or implicitly indicated through its transmission location and / or sequence. The terminal selects a subset of resources from the reserved resource set and sends beam recovery request information. The selection of the resource subset is determined based on the selected, qualified better beam ID and / or the terminal's UE ID, and its location implicitly indicates the better beam ID and / or the terminal's UE ID information. If multiple beam index reporting is supported, the UE can send beam recovery requests on multiple resource subsets.

[0177] The base station blindly detects the beam recovery request information sent by the UE, and obtains better beam indication information and / or UE ID information based on the resources used for uplink transmission. When reporting different content, the terminal transmission strategy will have corresponding configurations or conventions. The base station will then execute different steps, some of which can be categorized into several cases, including:

[0178] Scenario 1: The beam recovery information initially reported by the UE only includes the selected beam indication information.

[0179] Step 1001: In this case, during the execution of step 901 above, the terminal determines the uplink transmission resources (including time and frequency code resources) based on the selected beam ID. Within the configured subset of resources, the terminal sends a beam recovery request. The base station blindly detects the beam recovery request information sent by the UE and determines which new beam is selected based on the received time, frequency, and code resources during correct blind detection.

[0180] Step 1002: The base station transmits downlink control information on the corresponding new beam at the agreed location and allocates uplink Physical Uplink Shared Channel (PUSCH) resources. The agreed location can optionally be defined based on the reporting time of beam recovery information. Since it is unknown which UE's beam is experiencing a problem, the downlink control information can be scrambled using an agreed-upon method.

[0181] Step 1003: The terminal blindly detects the downlink control channel at an agreed location. The agreed location may be defined based on the time of beam recovery information reporting. If the terminal can successfully detect the downlink control channel, it can obtain the downlink control information. If multi-beam transmission is supported, the control channel can be detected in a multi-beam mode.

[0182] Step 1004: The terminal feeds back the UE ID information to the base station using the allocated uplink resources; after obtaining the UE ID information, the base station communicates with the UE using the control channel of the new beam. Since the communication link has been established and the control channel has been restored, beam training can be performed subsequently to obtain a better beam.

[0183] Case 2(a): The beam recovery content reported by the UE in the first report only includes the UE ID information, and channel reciprocity is established.

[0184] Step 1011a: In this case, during the execution of step 901 above, the terminal can select the optimal uplink transmission beam(s) based on reciprocity, and repeatedly transmit the beam recovery request multiple times using this beam within the configured resource subset. The base station blindly detects the beam recovery request information sent by the UE, and by comparing the resources such as reception time, frequency, and code during correct blind detection with the uplink transmission resources configured for each UE, the base station can determine which UE initiated the beam recovery request.

[0185] Step 1012a: The base station reciprocally obtains the optimal downlink transmit beam based on the optimal uplink receive beam, and uses this beam to transmit the downlink control channel.

[0186] Step 1013a: The terminal uses the downlink optimal receive beam corresponding to the optimal uplink transmit beam to detect the downlink control channel. The control link establishment process is then complete.

[0187] Case 2(b): The beam recovery information reported by the UE in the first report only includes the UE ID information, and the channel reciprocity is inaccurate.

[0188] Step 1011b: In this case, during the execution of step 901 above, the terminal needs to perform multiple uplink scans and transmissions. It can initially attempt to use a specific beam within a certain range. If unsuccessful, the range is expanded. During each transmission, within the configured subset of resources, the terminal repeatedly sends beam recovery requests using that beam.

[0189] Step 1012b: The base station blindly detects the beam recovery request information sent by the UE. By comparing the resources such as reception time, frequency, and code during correct blind detection with the uplink transmission resources configured for each UE, the base station can determine which UE made the beam recovery request.

[0190] Step 1013b: The base station assigns uplink resources to terminals requiring beam recovery by sending a dedicated DCI through the public PDCCH, specifically for beam ID reporting.

[0191] Step 1014b: The base station determines the transmission beam of the dedicated control channel using the reported ID, completing the control link establishment process. This control channel can be used for subsequent communication with the terminal, and further beam training can be performed to obtain a better beam.

[0192] The third scenario: The beam recovery information reported by the UE in the first step includes UE ID information and beam indication information.

[0193] Step 1021: In this case, following step 901 above, when the triggering condition is met, the terminal selects a subset of resources from the reserved resource set to send beam recovery request information. The selection of the resource subset is determined based on the resource set pre-configured by the base station for the UE and the downlink beam ID selected by the UE. The transmitted resources implicitly reflect which UE it originates from and what the optimal downlink beam ID measured by that UE is.

[0194] If reciprocity is good, the terminal can transmit using only the uplink beam obtained through optimal downlink beam reciprocity. If reciprocity is not ideal, the terminal can use multiple possible beams to transmit uplink beam recovery request information. If it is still not ideal, the beam range can be further expanded.

[0195] Step 1022: The base station blindly detects the beam recovery request information sent by the UE. By comparing the resources such as reception time, frequency, and code during correct blind detection with the uplink transmission resources configured for each UE, the base station can determine which UE made the beam recovery request.

[0196] Step 1023: The base station determines the transmit beam of the UE's dedicated control channel using the reported beam ID, completing the control link establishment process. This control channel can then be used for subsequent communication with the terminal, and further beam training can be performed to obtain a better beam. Specific Implementation Example 2:

[0198] The following are candidate types that can be used as reference signals for downlink beam recovery measurements:

[0199] Reference signal type 1: CSI Reference Signal;

[0200] Reference signal type 2: Common-PDCCH DMRS;

[0201] Reference signal type 3: Synchronization Signal;

[0202] Optionally, the above types can be configured by the base station, and each terminal can configure the beam recovery reference signal type separately;

[0203] A single terminal can support one or more types of beam recovery reference signals;

[0204] Base stations can also be configured with multiple sets of resources of the same type of pilot, such as configuring Channel State Information (CSI-RS) resource 1 and CSI-RS resource 2. The beam configurations of these two CSI-RS resources may differ, such as the beamwidth, the number of beams, and the number of ports. Terminals can perform beam recovery based on multiple sets of CSI-RS resources separately or jointly.

[0205] It should be noted that the beam recovery mentioned here includes two situations: one is for beam monitoring, and the other is for selecting a better beam. Specific Implementation Example 3:

[0207] The set of configuration information used for beam recovery includes one or more of the following:

[0208] First set of configuration information for beam quality monitoring

[0209] The first configuration information includes: the configuration of the reference signal to be monitored, and further includes the configuration information of the first reference pilot resource set, such as the configuration of the reference signal type, the configuration of the transmission resource indication, the transmission power, the location of the transmission time and frequency resource, the transmission precoding information, the resource numbering rules, the transmission antenna, etc.; it may also include some configurations of the receiving parameters.

[0210] There are several ways for a terminal to determine this initial configuration information. One way is through agreement, and another is through configuration signaling from the base station. In subsequent cases, the base station needs to determine the reference signal configuration and then send it to the terminal via higher-layer or physical-layer signaling.

[0211] Sub-implementation 1: Determining the beams to be monitored based on the beam configuration of the control channel

[0212] Option-1 of Sub-implementation 1: The transceiver agrees or the base station configures "a certain / some" control channels for the terminal. The terminal determines the beam currently in use by the control channel according to the beam configuration information and determines the measurement reference signal corresponding to the beam.

[0213] For example, if a base station configuration specifies a control channel that needs to be monitored, and the beam used by this control channel is based on the CSI-RS beam definition, then the object of beam recovery measurement is this CSI-RS; the terminal measures and monitors this CSI-RS.

[0214] For example, a base station configuration specifies two control channels that need to be monitored. One control channel uses a beam defined based on CSI-RS, while the other control channel uses a beam defined based on SS. Therefore, the beam recovery measurement targets this CSI-RS and SS; the terminal measures and monitors this CSI-RS and SS.

[0215] Another scenario involves a primary / secondary distinction in the control channel configuration. The transmitting and receiving ends agree to measure and monitor the reference signal corresponding to the beam currently used by the primary control channel. In this case, the base station does not need to specify the control channel to be detected. Therefore, no additional signaling is required, as this is a pre-agreed method.

[0216] Option-2 of sub-implementation 1: The terminal determines all control channels and the set of beams that can be used by all control channels according to the control channel related configuration. The beams included in the set of beams may correspond to X types / sets of measurement reference signals, and X types / sets of reference signals are measured.

[0217] For example, if a base station configures multiple control channels for a terminal, some defining the transmit beam based on CSI-RS resource 1 and others defining the beam based on CSI-RS resource 2, then the beam recovery reference object is CSI-RS resource 1 and / or CSI-RS resource 2.

[0218] For example, if a base station is configured with multiple control channels, some of which define the transmit beam based on CSI-RS resource 1, and others based on SS, then the beam recovery reference object is CSI-RS resource 1 and / or SS.

[0219] Sub-implementation 2: Base station configuration indication for beam recovery related measurement reference signals

[0220] The difference from the previous example is that the relationship with the control channel itself is not as strong here. The base station directly configures and specifies the type, number, and resource ID of the reference signals used for beam recovery-related measurements;

[0221] Specifically, the base station can specify the control channel beams or beam sets to be monitored from all candidate control channel beams. This set can include beams from multiple control channels. The terminal uses this set to determine the reference signal to be measured and the beam to be monitored. In more complex cases, this beam set can contain multiple types of beams defined based on different types of reference signals. For simplicity, the number and type of beams can be limited. The terminal determines the corresponding reference signal based on the beams included in the set.

[0222] It should be noted that multiple beams that need to be monitored can be supported. These multiple beams can be the same type of reference signal or different types of reference signals.

[0223] Second configuration information set for beam selection

[0224] This primarily includes the configuration of reference signals for beam selection, and further includes the configuration information of a second reference pilot resource set, such as transmit resource indication configuration, transmit power, transmit time-frequency resource location, transmit precoding information, resource numbering rules, transmit antenna, etc.; it can also include some configurations of receive parameters. The terminal can determine this configuration in several ways: one is through agreement, and another is through configuration signaling from the base station. In the latter case, the base station needs to determine the reference signal configuration and then send it to the terminal via higher-layer or physical-layer signaling.

[0225] It should be noted that multiple sets of reference signals for beam selection can be supported, and multiple selectable beams can be selected within a single set of reference signals. These multiple beams can be reference signals of the same type or reference signals of different types.

[0226] The third set of configuration information used for beam recovery information reporting;

[0227] Optionally, the beam recovery information includes: beam and / or receiver indication information. Other beam recovery-related information is not excluded. The third configuration information set includes beam recovery information transmission method indication, transmission resource indication, reporting content indication, reporting criteria, etc., such as how many beams to report and priority principles.

[0228] The fourth set of configuration information used to determine beam selection and / or reporting.

[0229] Optionally, the fourth set of configuration information used to determine beam selection and / or reporting includes: beam quality thresholds, such as determining whether a beam falls below a configured first threshold for a period of time during beam monitoring; determining whether the selected beam is above a configured second threshold during beam selection; and assigning configurations if multiple beams are being monitored. There are also some criteria for determining whether to select one or multiple beams. Specific Implementation Example 4

[0231] Optionally, the first set of reference pilot resources is a subset of M1 sets of reference pilot resources, and the second set of reference pilot resources is a subset of N1 sets of reference pilot resources, where M1 <= N1 and are both positive integers; optionally, the M1 sets of reference pilot resources are a subset of the N1 sets of reference pilot resources.

[0232] Optionally, the pilot resources in the first set of reference pilot resources include M2 ​​types of reference pilot resources, and the pilot resources in the second set of reference pilot resources include N2 types of reference pilot resources, where M2 <= N2 and are both positive integers; optionally, the M2 types of reference pilot resources are a subset of the N2 types of reference pilot resources.

[0233] Optionally, the candidate resource types of the first reference pilot resource set are type set X1, and the candidate resource types of the second reference pilot resource set are type set X2, where X1 is a subset of X2;

[0234] Optionally, the reference pilot resource type includes one or more of the following types: CSI ReferenceSignal; PDCCH DMRS; Synchronization Signal; Specific Implementation Example 5:

[0236] Optionally, the transmitter can configure "First Reference Pilot Resource Set / Subset" for different RRC state sets.

[0237] Optionally, the transmitter can configure "second reference pilot resource set / subset" for different RRC state sets;

[0238] Here, common RRC states include linked and idle states, and newly defined states may also occur. RRC states can be divided into multiple sets. For each set, a first reference pilot resource set / subset can be configured. For each set, a second reference pilot resource set / subset can be configured.

[0239] The receiving end can determine the corresponding first reference pilot resource set / subset for different Radio Resource Control (RRC) state sets. The receiving end can determine the corresponding first reference pilot resource set / subset by using the signaling configured by the base station in conjunction with the current RRC state. Alternatively, it can determine the corresponding first reference pilot resource set / subset by using agreed-upon rules / parameters in conjunction with the current RRC state.

[0240] The receiving end can determine the corresponding second reference pilot resource set / subset for different RRC state sets. The receiving end can determine the corresponding second reference pilot resource set / subset by using the signaling configured by the base station in conjunction with the current RRC state. Alternatively, it can determine the corresponding second reference pilot resource set / subset by using agreed-upon rules / parameters in conjunction with the current RRC state. Specific Implementation Example 6:

[0242] Optionally, the transmitter can configure "first reference pilot resource set / subset" for different beam recovery mode sets.

[0243] Optionally, the transmitter can configure "second reference pilot resource set / subset" for different beam recovery mode sets;

[0244] Here, multiple beam recovery modes can be defined. For example, the various processes in Specific Embodiment 3 can be defined as different beam recovery beams, and newly defined beam recovery modes may also emerge. Beam recovery modes can be divided into multiple sets. For each set, a first reference pilot resource set / subset can be configured. For each set, a second reference pilot resource set / subset can be configured.

[0245] The receiver can determine the corresponding first reference pilot resource set / subset for different beam recovery mode sets. The receiver can determine the corresponding first reference pilot resource set / subset using the signaling configured by the base station combined with the current beam recovery mode. Alternatively, it can determine the corresponding first reference pilot resource set / subset using agreed-upon rules / parameters combined with the current beam recovery mode.

[0246] The receiver can determine the corresponding second reference pilot resource set / subset for different beam recovery mode sets. The receiver can determine the corresponding second reference pilot resource set / subset using the signaling configured by the base station in conjunction with the current beam recovery mode. Alternatively, it can determine the corresponding second reference pilot resource set / subset using agreed-upon rules / parameters in conjunction with the current beam recovery mode. Specific Implementation Example 7:

[0248] Optionally, the transmitter can configure "first reference pilot resource set / subset" separately for different control channels.

[0249] Optionally, the transmitter can configure a "second reference pilot resource set / subset" for different control channels.

[0250] Here, the base station can be configured with multiple control channels, and these control channels will have different transmission methods. After dividing the control channel sets, a first reference pilot resource set / subset can be configured for each set. A second reference pilot resource set / subset can also be configured for each set.

[0251] The receiving end can determine the corresponding first reference pilot resource set / subset for different control channels. The receiving end can determine the corresponding first reference pilot resource set / subset using the signaling configured by the base station in conjunction with the currently used control channel. Alternatively, it can determine the corresponding first reference pilot resource set / subset using agreed-upon rules / parameters in conjunction with the currently used control channel.

[0252] The receiving end can determine the corresponding second reference pilot resource set / subset for different control channels. The receiving end can determine the corresponding second reference pilot resource set / subset by using the signaling configured by the base station in conjunction with the current control channel. Alternatively, it can determine the corresponding second reference pilot resource set / subset by using agreed-upon rules / parameters in conjunction with the current control channel. Specific Implementation Example 8:

[0254] The fourth configuration information includes configuration information for a "first preset condition set" used for beam selection and / or reporting; the preset conditions in the "first preset condition set" apply to the steps and / or results of beam quality monitoring.

[0255] The “first set of preset conditions” includes a preset condition of type “quality threshold”; the “quality threshold” condition is used to determine whether the monitored beam quality meets the conditions defined based on the quality threshold.

[0256] The "First Preset Condition Set" includes a preset condition of type "Time Window T1". This "Time Window T1" condition is used to limit the time range of beam measurement. For example, it might specify the number of times the quality falls below a threshold within the time window, whether the average quality is within a threshold, or whether the worst-case quality falls below a quality threshold within the time window. There can be many criteria, but a time window needs to be defined here. This time window T1 can be configured by the transmitter for the receiver, or it can be agreed upon by the transmitter and receiver.

[0257] The fourth configuration information includes the configuration information of the "second preset condition set" for beam selection and / or reporting; the preset conditions in the "first preset condition set" apply to the steps and / or results of beam selection or reporting.

[0258] The "Second Preset Condition Set" includes a preset condition of type "Quality Threshold"; this "Quality Threshold" condition is used to determine whether the quality of the selected beam meets the conditions defined based on this quality threshold. Only beams that meet the conditions can be reported.

[0259] Multiple quality thresholds can be set, each corresponding to a different selectable beam.

[0260] The "first set of preset conditions" includes a preset condition of type "time window"; this "time window" condition is used to limit the measurement time range for beam selection. There can be many criteria, but here a time window needs to be defined. This time window can be configured by the transmitter for the receiver, or it can be agreed upon by the transmitter and receiver. Specific Implementation Example 9

[0262] The configuration of the "first preset condition set" includes one or more of the following methods.

[0263] The transmitting end configures a "first preset condition set / subset" for different "first reference pilot resource sets / subsets" used for beam quality monitoring;

[0264] The sending end configures a "first preset condition set / subset" for each set of different RRC states.

[0265] The transmitting end configures a "first preset condition set / subset" for each different beam reporting method set.

[0279] The transmitting end configures a "third configuration information set / subset" for different "first reference pilot resource sets / subsets" used for beam selection;

[0280] The transmitting end configures a "third configuration information set / subset" for different "first reference pilot resource sets / subsets" used for beam selection;

[0283] The sending end configures a "third configuration information set / subset" for different sets of RRC states;

[0284] The transmitting end configures a "third configuration information set / subset" for different beam recovery modes;

[0285] The transmitting end configures a "third configuration information set / subset" for different control channels respectively; Specific Implementation Example 11:

[0287] If the UE transmits in a scanning manner, the base station may detect beam recovery requests on multiple uplink resources. In this case, it should be determined whether the requests originate from the same UE based on whether the sequences are identical. When multiple uplink beams are transmitted, the same sequence is used. Specific Implementation Example 12

[0289] In the preceding specific embodiments, we did not specify whether the beam quality measurement was based on the transmit / receive beam pair (BPL) or the transmit beam (Tx beam). Both transmit and receive beam variations contribute to BPL quality degradation, but beam recovery is handled differently. If a transmit beam variation is necessary to reach the quality threshold, beam recovery is required; otherwise, if the transmit beam remains unchanged while a receive beam variation achieves the quality threshold, beam recovery is unnecessary. The specific considerations are as follows:

[0290] Step 1: The base station configures the time window T2 for the terminal.

[0291] A base station can be configured with multiple T2s for different control channels / control beams / reference signals; T2s can be the same as or different from the preceding T1s.

[0292] Step 2: The terminal finds that the current BPL does not meet the quality requirements. The terminal needs to try to find a BPL quality higher than the corresponding threshold receiving beam within the time window without changing the transmitting beam.

[0293] Step 3: If a suitable receive beam is found in Step 2, no beam recovery request is initiated; if a good receive beam cannot be found in Step 2 (possibly due to limitations in pilot transmit density configuration) causing BPL quality to exceed the threshold, beam recovery is initiated. At this point, there are two possibilities:

[0294] - In Case a, if the terminal can find other BPLs that meet the conditions within the time window (the transmit beam has changed), the terminal reports the corresponding transmit beam information. If the control channel originally had multiple BPLs, and all of them met the beam recovery conditions, then there are several possible scenarios:

[0295] Completely independent reporting;

[0296] Set priorities, and report the highest priority.

[0297] - Case b: If the terminal cannot find another BPL that meets the conditions within the time window based on the reference signal resource set R corresponding to the BPL, but there is a BPL that meets the conditions in another reference signal resource set r, there are several possible scenarios.

[0298] If R cannot find a new beam recovery mechanism that satisfies the condition beam, then report the corresponding mechanism.

[0299] The base station is notified that a certain beam in the reference signal resource set r is available, and the reference signal resource set r is indicated during feedback.

[0300] - Case c: Within the time window, no other BPL that meets the conditions can be found based on all beam recovery measurement reference signals. There are several solutions.

[0301] The process of directly performing random access

[0302] If R cannot find a new beam recovery mechanism that satisfies the conditional beam, then the corresponding report is submitted. Specific Implementation Example 13

[0304] The receiver can determine the second set of reference signal resources based on the beam monitoring results.

[0305] For example, beam monitoring sets multiple thresholds, each corresponding to a different severity of quality issues. Different severity levels correspond to different second reference signal resources. Some sets of second reference signal resources correspond to more beams, while others correspond to fewer beams.

[0306] For example, beam monitoring involves multiple beams. Based on the location and / or number of beams experiencing problems, different severity levels of quality issues can be identified, each corresponding to a different set of second reference signal resources. Some sets of second reference signal resources correspond to more beams, while others correspond to fewer beams.

[0307] For example, beam monitoring has multiple beams, each corresponding to a different type of reference signal. These beams can each correspond to a different reference signal, and their corresponding second reference signal resources also differ. Some sets of second reference signal resources correspond to more beams, while others correspond to fewer beams.

[0308] Multiple thresholds, multiple beams, and different reference signal types can be agreed upon or configured as the corresponding second reference signal resource set. Specific Implementation Example 14

[0310] The time windows T1 or T2 mentioned above can be configured in the following ways.

[0311] The transmitter configures "T1 or T2" for different "first reference pilot resource sets / subsets" used for beam selection.

[0312] The transmitter configures T1 or T2 for different "second reference pilot resource sets / subsets" used for beam selection.

[0313] The sending end configures T1 or T2 for different sets / subsets of the first preset conditions;

[0314] The sending end configures T1 or T2 for different sets / subsets of the second preset conditions;

[0315] The sending end configures T1 or T2 for different sets of RRC states respectively;

[0316] The transmitting end is configured with either T1 or T2 for different beam recovery modes;

[0317] The transmitting end configures T1 or T2 for different control channels; Specific Implementation Example 15

[0319] The receiving end can determine the reporting resources, reporting methods, and reporting content of beam recovery information based on the beam monitoring results.

[0320] For example, beam monitoring sets multiple thresholds, each corresponding to a different severity of quality issues. Different severity levels require different reporting resources, methods, and content.

[0321] For example, beam monitoring has multiple beams. Depending on the location and / or number of beams where a problem occurs, different severity levels of quality issues can be identified. Different severity levels correspond to different reporting resources, reporting methods, and reporting content.

[0322] For example, beam monitoring involves multiple beams, each corresponding to a different type of reference signal. The corresponding reporting resources, reporting methods, and reporting content differ.

[0323] Multiple thresholds and beams can be agreed upon or configured, and the corresponding reporting resources / reporting methods / reporting content will differ under different reference signal types.

[0324] The reported resources may include one or more of the following: time-frequency space code power resources.

[0325] Reporting methods can be selected from: multi-beam / single-beam, number of transmissions, beam type, and transmission technology.

[0326] The reported content may include: Beam ID and / or UEID, one or multiple Beam IDs. Specific Implementation Example 16

[0328] The receiving end can determine the reporting resources / reporting method / reporting content of beam recovery information based on the beam selection result.

[0329] For example, in a joint selection scenario, the optimal beam source from different reference signal sets can correspond to different reporting resources / reporting methods / reporting content. In an independent selection scenario, the optimal transmission beam from different reference signal sets can correspond to different reporting resources / reporting methods / reporting content. Specific Implementation Example 17

[0331] The receiving end can determine the reporting resources / reporting method / reporting content of beam recovery information based on the beam selection result.

[0332] For example, the optimal beam may come from different sets of reference signals, and the corresponding reporting resources / reporting methods / reporting content may be different. Specific Implementation Example 18

[0334] Depending on the RRC status, beam recovery mode configuration, duplex mode, and control channel configuration, different reporting resources can be selected accordingly.

[0335] Different reporting methods can be selected;

[0336] You can select different reporting content.

[0337] These differentiated designs allow for more targeted beam recovery design. Specific Implementation Example 19

[0339] The number of resources within the second reference pilot resource set can be used to determine the size and location of the area where resources are reported.

[0340] Based on the type of the second reference pilot resource set, the reporting resources / reporting method / reporting content can be determined.

[0341] Alternatively, the pilot resources included in the second reference pilot set can be determined based on the size and location of the available reporting resource area. Specific Implementation Example 20

[0343] The transmitting and receiving ends agree on or configure the priority order for beam reporting, and the receiving end reports according to this priority order. When there is high-priority content to report, it is reported first, and low-priority content is not reported or is reported later.

[0344] High-priority content is reported using a more robust sending method, while low-priority content is reported using a normal method.

[0345] High-priority content consumes more reporting resources, while low-priority content consumes less reporting resources. Specific Implementation Example 21

[0346] The specific implementation example 3 mentioned above describes four beam recovery procedures. In procedure 1, the UE information is not required when the UE reports for the first time. In procedures 2a, 2b, and 3, the first step of the report will carry the UE information.

[0347] The reporting of UE information in processes 2a, 2b, and 3 can be considered in conjunction with the design of the uplink scheduling request (SR). Since the base station needs to know which UE information it is when acquiring SR information, one bit can be added to the SR content.

[0348] SR offers several sending modes to choose from, such as:

[0349] (1) The uplink transmits using the trained uplink transmit beam, and the base station receives using the trained beam;

[0350] (2) Multiple pre-trained transmit beams are used, and the base station uses the corresponding pre-trained transmit beam to receive;

[0351] (3) Repeatedly transmit using the trained transmit beam, and the base station performs receive beam scanning.

[0352] (4) Using multiple trained transmit beams, transmit repeatedly multiple times, and the base station performs receive beam scanning and reception on each of the multiple transmit beams.

[0353] (5) The terminal determines the transmitting beam itself and transmits multiple times using the same beam. The base station scans and receives the signals using the receiving beam. The terminal can switch beams itself (within an agreed range / or without restriction).

[0354] The case where beam recovery information is transmitted together should be case (5). Note that this may require that the transmission of SR also be carried out in a scanning manner.

[0355] As mentioned earlier, in the three procedures, procedure-1 requires the UE to carry beam ID information during its first report. The reporting of this information can be referenced from the design of the random access channel (PRACH). However, note that the reference pilot for beam recovery may not be the synchronization signal (SS), but rather the CSI-RS. The number of beams in the CSI-RS may differ from that of the SS. The PRACH phase does not actually have the capability for RRC / MAC layer configuration, while beam recovery does have the capability for RRC / MAC configuration signaling. Therefore, the uplink resource configuration differs here. Beam recovery is generally faster than SS, so the time-domain density requirement is also higher. Specific Implementation Example 22

[0357] The preceding specific embodiments mentioned that beam recovery can be performed based on measurements from the SS, CSI-RS, and common physical downlink control channel (PDCCH). Different measurement reference signals can correspond to different / independent configurations, including:

[0358] - Transmission area configuration; for example, different frequency domain resources result in different time domain densities. (This may be related to RS configuration.)

[0359] - Transmission method configuration: Different sequence usages result in different transmission modes. (This may be related to RS configuration)

[0360] - Considerations for what to carry: Some carry a lot of things, while others carry less.

[0361] -Different beam recovery processes: Different recovery processes correspond to different RS

[0362] -Different reporting methods: Different recovery processes correspond to different RS Specific Implementation Example 23

[0364] As mentioned earlier, if the conditions cannot be met, one approach is to directly proceed with the RACH process. Another approach is to send an uplink beam scan, but without carrying the beam ID, only carrying the UE ID information. This could be a reporting design and resource configuration specifically designed for this situation. This case of not carrying the beam ID should be distinguished from process 2a mentioned in the previous specific embodiment 3. Specific Implementation Example 24

[0366] When specifying downlink beams, different DCI formats can be used to designate different beams.

[0367] For example, DCI Format A corresponds to the SS beam; DCI Format B corresponds to the CSI-RS beam; and DCI Format C corresponds to the beam defined by PDCCH DMRS.

[0368] In the case of non-beam recovery, a DCI format-specific detection period can be configured.

[0369] In the case of beam recovery, if the beam recovery was previously initiated based on a certain type of reference signal, the corresponding DCI format will be continuously detected within the agreed time range after reporting. Specific Implementation Example 25

[0371] Different degrees of beam quality issues correspond to different reference signal resource subsets (RS). For more severe cases, the subset should contain more beam resources or use a wider beam. However, if the beam quality is not very severe, or if the rate of decay merely exceeds a preset threshold without significant actual quality degradation, it may mean that the optimal beam is still near the original beam. Therefore, the subset can contain fewer pilot resources, resulting in lower beam quantization overhead. Similarly, problems with different types of beams (CSI-RS beam and / or SS beam) may also correspond to different RS resource subsets. Reference Signal (RS) and Synchronize Signal (SS) are also relevant. Specific Implementation Example 26

[0373] Base stations can configure quality thresholds and time windows for beam monitoring. Within this time window, if the terminal detects that the beam quality consistently fails to exceed the quality threshold, or that the beam quality degrades very rapidly, beam selection and reporting need to be triggered. Within this time window, if there are multiple transmission opportunities for the monitored beam, the terminal can attempt to change the receiving beam to achieve better reception quality. The base station can configure the corresponding quality thresholds and time windows separately for different beams, because different beams may have different widths, and their corresponding reference signal transmission time-domain configurations may also differ. For the same beam, the base station can also configure different quality thresholds, with different quality threshold configurations representing different degrees of severity of the beam problem. Specific Implementation Example 27

[0375] The beam selection time window can also be different for different beam severity levels. The more severe the beam problem, the longer the time window will generally be, which gives a greater opportunity to measure more transmit and receive beam pairs.

[0376] Different beam quality issues can correspond to different beam reporting modes. For example, beam problems with severe quality issues can use the first mode, while beam problems with moderate quality issues can use the third mode; that is, different beam reporting modes can be used for the two types of issues. It should be noted that the beam reporting mode is the mode for reporting beam recovery information. Specific Implementation Example 28

[0378] The reference signal resource set used for beam selection can consist of various types of reference signals, such as SS beams and CSI-RS beams. The terminal can perform beam selection within this set, and the optimal beam may be a CSI-RS beam or an SS beam.

[0379] If the base station cannot determine which type of RS the UE will report, the terminal needs to indicate the RS type when reporting.
