Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, specifically to beam distribution methods, devices, electronic devices, and storage media. Background Technology
[0002] Due to limitations such as protocol constraints, chip / terminal capabilities, and beam scanning overhead, the number and shape of beams in SSB / TRS and CSI-RS are different. SSB is mainly used for user access and wide beam coarse scanning, TRS is mainly used for downlink frequency offset measurement, and CSI-RS is mainly used for narrow beam fine scanning and as the transmit beam of PDSCH.
[0003] Generally, TRS has a wider beam and CSI-RS has a narrower beam. In typical coverage scenarios, timing errors may occur due to the differences in beam width and coverage. Taking SCS 30kHz as an example, the CP length is 2.34µs, and the maximum measured multipath path difference is about 700m. When multipath phenomena occur due to factors such as reflection and refraction, the typical scenario is that the outdoor macro base station beam penetrates the glass or is reflected multiple times by the building before penetrating the glass. This may cause timing errors for indoor users and affect the user experience. Summary of the Invention

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] For ease of writing, this application uses English abbreviations. The following is an explanation of some of the English abbreviations used in this application:
[0025] DCI: Downlink Control Information;
[0026] NR: New Radio;
[0027] SSB: Synchronization Signal Block;
[0028] TRS: CSI-RS for Tracking;
[0029] Considering the scanning overhead of TRS and CSI-RS signals, base stations are usually designed to be universally applicable for measuring all users within the cell. This is optimal for overall network performance, and due to protocol constraints and terminal capabilities, the number of TRS beams is less than the number of CSI-RS beams.
[0030] However, TRS and CSI-RS are designed as cell-level signals, which have little impact on users at near-term and LOS locations. But in scenarios where outdoor macro base station beams penetrate glass or are reflected multiple times by buildings before penetrating glass, they may cause timing errors for indoor users, affecting user experience. If a user cannot be scheduled normally, it may affect the scheduling resources of other users, thereby affecting the overall network performance.
[0031] Based on this, this application proposes a method for beam allocation on the base station side. Please refer to [link / reference]. Figure 1-2 , Figure 1 This is a flowchart illustrating an embodiment of the base station-side beam allocation method of this application. Figure 2 This is a schematic diagram of an embodiment of the base station transmission beam of this application. In this embodiment, the beam allocation method on the base station side includes steps S110 to S150, each step of which is as follows:
[0032] S110: Sends TRS and CSI-RS beams to surrounding user equipment.
[0033] Depend on Figure 2As can be seen, the signal base station can transmit TRS and CSI-RS beams, with the TRS beam being wider and the CSI-RS beam narrower. The user equipment in building 1 is a near-center user equipment, while the user equipment in building 2, when receiving the beam, may experience reflections from building 1 before penetrating the glass environment. In this case, the signal base station can use the beam allocation method of this embodiment to ensure normal timing for indoor users in building 2. The TRS and CSI-RS beams can be determined by the SSB.
[0034] CSI-RS (Channel State Information-Reference Signal) is a very important reference signal in NR systems. Wireless channel conditions may change constantly, and user equipment needs to feed back the downlink channel conditions it sees to the base station (eNodeB) through CSI so that the base station can take channel quality into account when scheduling downlink.
[0035] CSI-RS is used in scenarios including downlink channel state information acquisition (DL CSI Acquisition), beam management, fine time-frequency tracking, radio resource management measurement (RRM), radio link monitoring measurement (RLM), beam failure detection (BFD), uplink channel state information acquisition (UL CSI Acquisition), and PDSCH rate matching. In this embodiment, CSI-RS is primarily used for beam management, i.e., CSI-RS for BM.
[0036] After a user equipment is powered on or moved to a new cell coverage area, it needs to obtain downlink synchronization with the network through the downlink synchronization channel. This includes time and frequency synchronization, obtaining the cell's physical cell identity (PCID), and reading the cell's broadcast information to obtain the cell's system information to determine subsequent operations, such as camping, cell reselection, and initiating random access.
[0037] S120: Receive the reporting results sent by the preset user equipment.
[0038] The reported results from the pre-defined user equipment (UE) include the optimal CSI-RS beam measured by the UE itself and the TRS beam in which the UE is located. The process of the UE reporting its optimal CSI-RS beam can be broadly divided into two stages: First, the signal base station sends CSI-RS and / or SSB to the UE according to the CSI resource configuration. Second, the UE measures the CSI-RS and / or DM-RS (located on the PBCH of the SSB) and reports the CSI-RS to the signal base station according to the CSI report configuration. After receiving the CSI-RS reported by the UE, the signal base station can perform beam management, channel-dependent scheduling, and other operations accordingly.
[0039] The user equipment (UE) obtains the RSRP (Reference Signal Receiving Power) of the transmit and / or receive beams corresponding to each CSI-RS resource by measuring the CSI-RS resource packet (containing multiple CSI-RS resources) configured for it. Based on the measurement results, the UE feeds back its recommended transmit / receive beams to the base station.
[0040] In addition, based on the reported results from the preset user equipment, the signal base station can determine the TRS beam in which the preset user equipment is located.
[0041] S130: Determine the optimal TRS beam for the preset user equipment based on the preset TRS beam and the optimal CSI-RS beam measured by itself.
[0042] The signal base station can determine the optimal TRS beam for a given user equipment based on the TRS beam where the user equipment is located and its own measured optimal CSI-RS beam. Optionally, this can be obtained through beam scanning.
[0043] Beam scanning refers to transmitting downlink synchronization channels using beamforming. Since only users within the beam's coverage area can receive the beamformed downlink synchronization channel, user equipment outside the coverage area cannot reliably receive it.
[0044] The downlink synchronization channel is a broadcast channel that requires all user equipment within the cell to receive it. A single beam with a limited coverage angle cannot actually meet the requirement of full cell coverage. Therefore, multiple beams are used to repeatedly transmit the downlink synchronization channel in different directions, and these beams can be combined to cover the entire cell.
[0045] Multiple beams are typically transmitted in turn at different times, hence the term beam scanning. Therefore, beam scanning allows the user equipment (UE) to obtain its optimal CSI-RS beam based on its own measurements. After receiving the reported results from the UE, the signal base station can adjust the UE's TRS beam according to the optimal CSI-RS beam.
[0046] It should be noted that the TRS beam initially sent by the signal base station to surrounding user equipment is a wide TRS beam; however, the optimal TRS beam sent after adjustment based on the reported results is a narrow TRS beam similar to the CSI-RS beam.
[0047] S140: Send the optimal TRS beam to the preset user equipment.
[0048] After the signal base station determines the optimal TRS beam, it can send the optimal TRS beam to the user equipment. The optimal TRS beam and the optimal CSI-RS beam are consistent, which can solve the timing error problem and improve the ability of outdoor network to cover indoor areas.
[0049] In CSI-ReportConfig, CRI-RSRP and SSB-Index-RSRP are configured for the UE. The user equipment reports its measured optimal SSB and CSI beams. The base station can determine the beam the terminal is in by the reported results, and thus determine its optimal TRS beam. The optimal TRS beam is consistent with the optimal CSI-RS beam.
[0050] In one embodiment, the step of sending the optimal TRS beam to a preset user equipment includes:
[0051] For a predefined user equipment, user-level TRS resource transmission is triggered; the TRS resource is configured via RRC and has a corresponding QCL relationship with CSI-RS. QCL (Quantum Cascade Laser) refers to the inference of the channel attributes of a channel transmitting symbols on one antenna interface from the channel transmitting symbols on the other antenna port.
[0052] Optionally, the QCL relationship between TRS and CSI-RS can be configured as either Type A or Type B. RS plays a crucial role in the precise time-frequency synchronization of the entire system. CSI-RS needs to obtain Type A or Type B information from TRS. For DMRS, depending on the specific signaling, the required Type A information may be obtained directly from TRS or indirectly through CSI-RS.
[0053] In one embodiment, after the step of initiating user-level TRS resource transmission for a preset user equipment, the method further includes:
[0054] A measurement command is sent to a preset user equipment to enable the preset user equipment to perform time-frequency offset measurement on the TRS resource in response to the measurement command. The indication method typically includes PDCCH MAC CE.
[0055] When user equipment receives downlink data, it needs to continuously track and compensate for time and frequency offsets. The TRS resources provided by the TRS beam primarily serve this function.
[0056] The resource set of a TRS can be configured as periodic or aperiodic. A periodic TRS is a resource set containing multiple periodic CSI-RS resources; each CSI-RS resource is a 1-port CSI-RS resource with a frequency domain density of 3; the TRS symbol interval in each time slot is 4, inheriting the time domain interval of LTE CRS; TRS only supports 1 port.
[0057] Aperiodic TRS has the same structure as periodic TRS: bandwidth, frequency domain location, number of time slots, etc. Aperiodic TRS is triggered by DCI. User equipment does not need to report TRS measurements via CSI.
[0058] In this embodiment, the signal base station receives the optimal CSI-RS beam reported by the preset user equipment and determines the TRS beam through the optimal CSI-RS beam, so that the optimal TRS beam is as consistent as possible with the optimal CSI-RS beam. This solves the problem of excessive interference caused by the outdoor signal base station beam penetrating glass or being reflected multiple times by buildings before penetrating glass, which leads to timing errors for indoor users. This improves the ability of outdoor network to cover indoor areas and enhances the user experience.
[0059] Please see Figure 3 , Figure 3 This is a flowchart illustrating an embodiment of the user-side beam allocation method of this application. In this embodiment, the user-side beam allocation method may include steps S310 to S330, each step of which is as follows:
[0060] S310: Measure the CSI-RS beam received by the preset user equipment and determine the optimal CSI-RS beam.
[0061] S320: Send the reported results to the signal base station.
[0062] The reported results include the optimal CSI-RS beam corresponding to the user equipment and the preset TRS beam where the user equipment is located.
[0063] S330: Optimal TRS beam transmitted by the receiving signal base station.
[0064] The optimal TRS beam is aligned with the optimal CSI-RS beam.
[0065] In one embodiment, receiving the optimal TRS beam transmitted by the signal base station includes: receiving user-level TRS resources transmitted by the signal base station; wherein the TRS resources are configured via RRC and configured with corresponding QCL relationships with CSI-RS.
[0066] In one embodiment, after receiving user-level TRS resources from a signal base station, the method further includes: responding to a measurement command to perform time-frequency offset measurement on the TRS resources.
[0067] In summary, this application provides two beam allocation methods, applied to the base station side and the user side respectively. The base station-side beam allocation method includes: sending TRS beams and CSI-RS beams to surrounding user equipment; receiving a report from a preset user equipment, wherein the report includes the optimal CSI-RS beam measured by the preset user equipment itself and the TRS beam in which the preset user equipment is located; determining the optimal TRS beam in which the preset user equipment is located based on the TRS beam in which the preset user equipment is located and the optimal CSI-RS beam measured by itself; wherein the optimal TRS beam and the optimal CSI-RS beam are consistent; and sending the optimal TRS beam to the preset user equipment.
