Background
In a communication system adopting beam scanning, a base station can perform downlink beam optimization during the random access of UE (user equipment), so that the UE can obtain better beam forming gain.
Currently, a base station may trigger beam optimization before sending a random access response message to a UE (User Equipment). Specifically, the base station may employ a Reference signal, such as a CSI-RS (Channel State Information references signal), to indicate the narrow beam quality, and the CSI-RS indicating the narrow beam quality is directly associated with a RACH (Random Access Channel) resource. When the UE needs to report that a certain CSI-RS is the best CSI-RS to the base station, the UE selects RACH resources associated with the CSI-RS to transmit a preamble. After the base station detects the preamble on a certain RACH resource, the base station can know which CSI-RS the UE is to report to, according to the RACH resource, so as to know which narrow beam is the best one for replying to the corresponding narrow beam for random access.
In the process of implementing the invention, the inventor finds that at least the following technical problems exist in the prior art:

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiment of the present invention, the base station transmits the synchronization signal block on the downlink beam of the same type, which is referred to as a wide beam for short, and the UE can obtain the quality of the wide beam of the base station by measuring the synchronization signal block. The base station transmits a reference signal for reflecting the beam quality on another type of downlink beam, which is called a narrow beam for short, and is called a beam quality reference signal for short. The UE may obtain the quality of the narrow beam of the base station through measurement of a beam quality reference signal, which may be a CSI-RS reference signal for reflecting the beam quality, or other reference signals for reflecting the beam quality. The wide beam coverage of the base station can cover more than one narrow beam, and compared with the wide beam, the UE can obtain higher beamforming gain through the narrow beam.

The correlation between the synchronization signal block and the beam quality reference signal reflects the correlation between the wide beam and the narrow beam.
For example: when the base station configures the wide beam a to be associated with the narrow beam a1, the narrow beam a2, the narrow beam A3 and the narrow beam a4, the base station configures the synchronization signal block a to be associated with the beam quality reference signal a1, the beam quality reference signal a2, the beam quality reference signal A3 and the beam quality reference signal a4, wherein the UE can obtain the quality condition of the wide beam a by detecting the synchronization signal block a and can obtain the quality condition of the narrow beam a1, the narrow beam a2, the narrow beam A3 and the narrow beam a4 by detecting the beam quality reference signal a1, the beam quality reference signal a2, the beam quality reference signal A3 and the beam quality reference signal a 4. When the base station configures wide beam B to be associated with narrow beam B1, narrow beam B2, narrow beam B3, narrow beam B4, and other associated cases, similar to the above configuration, further description is omitted.
The association relationship between the synchronization signal block and the RACH resource reflects the association relationship between the wide beam and the RACH resource.
The association relationship between the synchronization signal block and the RACH resource includes: one synchronization signal block is associated with a set of RACH resources, including more than one RACH resource; when UE needs to report that a certain synchronous signal block is the best synchronous signal block to a base station, the UE sends a lead code on RACH resources associated with the synchronous signal block; when the base station detects the preamble on a certain RACH resource, the base station can know which best synchronization signal block the UE needs to report according to which RACH resource the RACH resource belongs to.
The association between the beam quality reference signal and the preamble resource reflects the association between the narrow beam and the preamble resource. Specifically, the following three cases may be included:
case 1: the association relationship between the beam quality reference signal and the preamble resource includes: for a certain synchronization signal block, when N beam quality reference signals are associated with the synchronization signal block, the base station divides available preamble resource into N groups, each beam quality reference signal is associated with a group of preamble resource, and different beam quality reference signals are associated with different preamble resource groups; when UE needs to report that a certain beam quality reference signal is the best beam quality reference signal to a base station, a lead code sent by the UE belongs to a lead code resource group associated with the beam quality reference signal; when the base station detects the preamble on a certain RACH resource, the base station can know which beam quality reference signal the best beam quality reference signal to be reported by the UE is according to which preamble resource group the preamble belongs to.
Case 2: the association relationship between the beam quality reference signal and the preamble resource includes: for a synchronization signal block, when there are N beam quality reference signals associated with the synchronization signal block, each beam quality reference signal is associated with all available preamble resources, and different beam quality reference signals are distinguished by preambles using different OCCs (Orthogonal Cover codes); when UE needs to report that a certain beam quality reference signal is the best beam quality reference signal to a base station, a lead code sent by the UE adopts an OCC (optical code correction) associated with the beam quality reference signal; when the base station detects a preamble on a certain RACH resource, the base station can know which beam quality reference signal the best beam quality reference signal to be reported by the UE is according to the OCC adopted by the preamble.
Case 3: the association relationship between the beam quality reference signal and the preamble resource includes: for a synchronization signal block, when N beam quality reference signals are associated with the synchronization signal block, each beam quality reference signal is associated with all available preamble resources, and different beam quality reference signals are distinguished by preambles using different masks; when UE needs to report that a certain beam quality reference signal is the best beam quality reference signal to a base station, a mask associated with the beam quality reference signal is adopted by a lead code sent by the UE; when the base station detects a preamble on a certain RACH resource, the base station can know which beam quality reference signal the best beam quality reference signal to be reported by the UE is according to a mask used by the preamble.
Specifically, the base station may provide the configuration of the RACH Resource and the preamble Resource for the UE in a mode of RMSI (Remaining system information) broadcast or RRC (Radio Resource Control) signaling.
After the base station resolves a specific preamble on a specific RACH resource, the base station can know the best synchronization signal block indicated by the UE and the best beam quality reference signal associated with the synchronization signal block, and then the base station can know the best wide beam and narrow beam for the UE, so that the base station can reply a random access response message to the UE on the known narrow beam to obtain a higher beam forming gain, that is, the downlink beam optimization of the base station is realized before the random access response message.
An embodiment of the present invention provides another method for implementing beam optimization, where the method is applied to a user equipment, and as shown in fig. 2, the method includes:
and S21, measuring the synchronous signal block sent by the base station and determining the best synchronous signal block.
The UE obtains the quality information of the synchronization signal block, i.e. obtains the quality information of the wide beam corresponding to the synchronization signal block, through the measurement of the synchronization signal block. And the UE judges and acquires the best synchronous signal block based on the measurement result of the synchronous signal block.
And S22, determining the beam quality reference signal associated with the best synchronization signal block according to the association relationship between the synchronization signal block and the beam quality reference signal.
And S24, measuring the beam quality reference signal associated with the best synchronization signal block, and determining the best beam quality reference signal.
The UE obtains quality information of the beam quality reference signal associated with the best synchronization signal block, i.e., obtains quality information of the narrow beam associated with the wide beam, by measuring the beam quality reference signal associated with the best synchronization signal block. The UE may determine to know the best beam quality reference signal based on the measurement result of the beam quality reference signal.
S23, determining the specific random access channel resource associated with the best synchronization signal block according to the association relationship between the synchronization signal block and the random access channel resource, and determining the specific preamble associated with the best beam quality reference signal according to the association relationship between the beam quality reference signal and the preamble resource.
S24, transmitting the specific preamble to the base station on the specific random access channel resource, so that the base station determines the best narrow beam according to the specific random access channel resource and the specific preamble.
The UE transmits the selected specific preamble on the selected specific RACH resource indicating to the base station the best synchronization signal block received by the UE, and the specific preamble indicating to the base station the best beam quality reference signal received by the UE.
And S25, receiving the random access response message sent by the base station on the optimal narrow beam.
Optionally, before step S21, the method further comprises:
receiving the incidence relation between the synchronization signal block and the beam quality reference signal, the incidence relation between the synchronization signal block and the random access channel resource and the incidence relation between the beam quality reference signal and the lead code resource which are sent by the base station.
Specifically, the UE may obtain the configuration of the RACH resource and the preamble resource from the base station through RMSI broadcast or RRC signaling before initiating random access to the base station.
According to the method for realizing beam optimization provided by the embodiment of the invention, in the random access process of the UE, the base station completes downlink beam optimization before sending the random access response message to the UE, and meanwhile, the base station utilizes the association relation between the wide beam and the narrow beam, utilizes the hierarchical measurement of the wide beam and the narrow beam by the UE and utilizes the hierarchical combined indication and identification of random access channel resources and lead codes, so that the expense of the UE can be reduced, the measurement time delay is reduced, and the utilization rate of RACH resources can be improved.
The method for implementing beam optimization according to the present invention is described in detail below with specific embodiments.
Example 1:
the base station side is configured with 3 synchronous signal blocks, which are respectively: synchronization signal block a, synchronization signal block B, synchronization signal block C, each of which may reflect the quality of one wide beam of the base station. The base station configures 12 beam quality reference signals, each of which may reflect the quality of one narrow beam of the base station. Each synchronization signal block is associated with 4 beam quality reference signals (synchronization signal block a is associated with beam quality reference signal a1, beam quality reference signal a2, beam quality reference signal A3, beam quality reference signal a4, synchronization signal block B is associated with beam quality reference signal B1, beam quality reference signal B2, beam quality reference signal B3, beam quality reference signal B4, synchronization signal block C is associated with beam quality reference signal C1, beam quality reference signal C2, beam quality reference signal C3, beam quality reference signal C4), respectively.
The base station provides the configuration condition of the RACH resource and the preamble resource for the UE through RMSI broadcast or RRC signaling, and the UE can obtain the configuration condition of the RACH resource and the preamble resource from the base station before initiating random access to the base station, where the configuration condition of the RACH resource and the preamble resource in this embodiment is:
(1) correlation of synchronization signal block with beam quality reference signal:
the synchronization signal block a associates the beam quality reference signal a1, the beam quality reference signal a2, the beam quality reference signal A3, the beam quality reference signal a 4;
the synchronization signal block B associates the beam quality reference signal B1, the beam quality reference signal B2, the beam quality reference signal B3, the beam quality reference signal B4;
the synchronization signal block C associates the beam quality reference signal C1, the beam quality reference signal C2, the beam quality reference signal C3, the beam quality reference signal C4;
the correlation between the wide beam and the narrow beam reflected by the correlation between the synchronization signal block and the beam quality reference signal is as follows:
wide beam a correlates narrow beam a1, narrow beam a2, narrow beam A3, narrow beam a 4;
wide beam B correlates narrow beam B1, narrow beam B2, narrow beam B3, narrow beam B4;
wide beam C correlates to narrow beam C1, narrow beam C2, narrow beam C3, and narrow beam C4.
(2) Association of synchronization signal block with RACH resource:
each synchronization signal block is associated with a set of RACH resources, where the set of RACH resources includes more than one RACH resource, for example, the synchronization signal block a is associated with a RACH resource group a, where the RACH resource group a includes 2 RACH resources, and so on, which will not be described again.
(3) Association relation of beam quality reference signal and preamble resource
For the embodiment, each synchronization signal block has 4 beam quality reference signals associated with the synchronization signal block, the base station divides available preamble resources into 4 groups, each beam quality reference signal is associated with one group of preamble resources, different beam quality reference signals are associated with different groups of preamble resources, for example, when 64 available preamble resources (preamble 1 to preamble 64) are available in total, the base station may divide the 64 preamble resources into 4 groups, associate the 4 groups with 4 beam quality reference signals associated with the synchronization signal block a, associate the 4 groups with 4 beam quality reference signals associated with the synchronization signal block B, and associate the 4 groups with 4 beam quality reference signals associated with the synchronization signal block C. Here, different grouping manners may be adopted for the beam quality reference signals associated with different synchronization signal blocks. For example, the 1 st to 16 th preambles are associated with beam quality reference signal a1, the 17 th to 32 th preambles are associated with beam quality reference signal a2, the 33 th to 48 th preambles are associated with beam quality reference signal A3, and the 49 th to 64 th preambles are associated with beam quality reference signal a 4; as another example, the 1 st to 16 th preambles are associated with a beam quality reference signal a1, the 17 th to 32 th preambles are associated with a beam quality reference signal a2, the 33 th to 48 th preambles are associated with a beam quality reference signal a4, and the 49 th to 64 th preambles are associated with a beam quality reference signal A3.
The UE obtains quality information of the synchronization signal block by measuring the synchronization signal block, and determines to acquire an optimal synchronization signal block based on a measurement result of the synchronization signal block, for example, the UE determines to acquire that the synchronization signal block a is the optimal synchronization signal block. Then, the UE measures the beam quality reference signal associated with the synchronization signal block a to obtain quality information of the beam quality reference signal associated with the synchronization signal block a, and the UE determines to know the best beam quality reference signal based on the measurement result of the beam quality reference signal, for example, the UE determines to know that the beam quality reference signal a2 is the best beam quality reference signal.
The UE transmits the selected specific preamble on the selected specific RACH resource, the specific RACH resource indicates to the base station the best synchronization signal block received by the UE, and the specific preamble indicates to the base station the best beam quality reference signal received by the UE, for example, in this embodiment, the UE indicates that the best synchronization signal block known by the UE is synchronization signal block a and the best beam quality reference signal known by the UE is beam quality reference signal a2 by selecting one RACH resource from RACH resource group a and transmitting preamble 18 on the resource to the base station.
After the base station resolves the preamble 18 on a certain RACH resource in the RACH resource group a, the base station may know that the best synchronization signal block indicated by the UE is the synchronization signal block a and the best beam quality reference signal associated with the synchronization signal block is the beam quality reference signal a2, and then the base station may know that the best wide beam for the UE is the wide beam a and the best narrow beam is the narrow beam a2, so that the base station may reply a random access response message to the UE on the known narrow beam a2 to obtain a higher beamforming gain, i.e., implement downlink beam optimization of the base station before the random access response message.
Example 2:
the base station side is configured with 3 synchronous signal blocks, which are respectively: synchronization signal block a, synchronization signal block B, synchronization signal block C, each of which may reflect the quality of one wide beam of the base station. The base station configures 12 beam quality reference signals, each of which may reflect the quality of one narrow beam of the base station. Each synchronization signal block is associated with 4 beam quality reference signals (synchronization signal block a is associated with beam quality reference signal a1, beam quality reference signal a2, beam quality reference signal A3, beam quality reference signal a4, synchronization signal block B is associated with beam quality reference signal B1, beam quality reference signal B2, beam quality reference signal B3, beam quality reference signal B4, synchronization signal block C is associated with beam quality reference signal C1, beam quality reference signal C2, beam quality reference signal C3, beam quality reference signal C4), respectively.
