Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for beam management of an intermediate node.
Background
An intermediate node (IRS) is based on controlling the propagation of electromagnetic waves in a communication channel to improve the performance of the communication system. For example, an Intelligent Reflective Surface (IRS) is a metasurface composed of a large number of tiny elements that diffusely reflect an incident signal in a controlled manner. The IRS is based on the classic concept of a reconfigurable reflection array, and the requirements of real-time reconfigurability and control are increased.
5G R15 standardizes the beam failure recovery procedure based on non-competitive access for PCell and Pscell, when a beam failure is detected, the terminal selects a new beam meeting the threshold requirement and initiates non-competitive random access on the PRACH resource of the new beam managed random access channel. After receiving the random admission request, the base station determines the new beam and sends a response message in a control set CORESET (CORESET-BFR) dedicated to beam failure recovery. After receiving the response message, the terminal receives the PDCCH in the CORESET-BFR by using a new beam, and uses the beam of the latest random access channel as the sending beam of the PUCCH until the terminal receives the RRC message of the Transmission Configuration Index (TCI) reconfiguration or the MAC CE signaling activated by the TCI.
Compared with a system without an intermediate node, the intermediate node adjusts the beam direction, so that the beam direction received by the terminal and the beam direction sent by the base station can change along with the phase adjustment of the intermediate node, when a beam failure recovery mechanism is considered, the terminal needs to report a new candidate beam, the base station can obtain candidate beam information reported by the terminal through the detected PRACH by adopting a random access channel and establishing a one-to-one correspondence with reference signals corresponding to candidate downlink beams, and the phase of the beam information is adjusted by the intelligent super surface, so that the correspondence between the random access channel and the reference signals corresponding to the downlink beams is changed, and the existing beam management mechanism and the beam failure recovery mechanism are not suitable.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, 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 application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an IRS enhanced multi-antenna wireless communication system.
IRS is a passive device, similar to a dish antenna used in satellite receivers, that reflects signals to improve signal-to-noise ratio. The different phase-shifted modes of its different element surfaces cause the incident signal to be reflected as a beam in different directions. IRS is a complement to traditional massive MIMO technology, unlike massive MIMO systems and cooperative relaying, although IRS also attempts to improve propagation conditions by deploying active hardware components, IRS requires only little operating power and is therefore suitable for implementation in energy-limited systems. Furthermore, IRS can naturally operate in full duplex without the need for costly self-interference cancellation. Furthermore, IRS is a very thin material that can be deployed on building facades and interior walls. Thus, once a legacy network is deployed, one or more IRSs can be flexibly deployed to mitigate detected coverage holes, or to provide additional capacity in areas where needed.
Two types of beamforming are facilitated by deploying an intermediate node in a conventional MIMO system, as shown in fig. 1, where an IRS is deployed in a system to facilitate communication between a multi-antenna transmitter and a user. An information signal is radiated from the transmitter and a direct path for communication may exist between the transmitter and the user, while the IRS also receives the information signal and will reflect the signal, with the infrared controller, the primary direction of the reflected signal can be controlled. In particular, appropriate phase shifts are introduced on all the element atoms to deliberately create a coherent combination of their respective scattered signals to produce a signal beam focused on the user, the larger the surface, the narrower the beam, a strategy known as energy focusing.
On the other hand, if there is no direct path due to severe shadowing or blockage, the transmitter should beam-form the IRS. The IRS may then act as a non-amplified full duplex relay, reflecting and focusing the signal to the end device UE to assist end-to-end communication. In fig. 1, consider a scenario where a multi-antenna transmitter serves user 1 in the presence of user 2. Assume that the two UEs have different security levels where the user 1 message cannot be decoded on user 2. In this case, by adjusting the phase of the scattered signal to stop the signal at the user 2, a destructive reflection can be made at the IRS, a strategy known as energy nulling.
Using these two principles, the irs is expected to have wide application in various communication systems, including interference management, coverage extension, and capability improvement, such as wireless communication systems, cognitive radio networks, physical layer security systems, and the like.
The intermediate node in the present application is not limited to the use of the IRS technology, but is configured to improve the performance of the communication system by controlling the waveform parameters of the electromagnetic waves propagating through the communication channel by reflection, refraction, or the like.
Fig. 2 is an embodiment of a method flow of an embodiment of the present application.
The embodiment of the application provides a beam management method of an intermediate node, which is used for a mobile communication system, wherein the mobile communication system comprises network equipment, an intermediate node device and user equipment, downlink information generated by the network equipment is directly received by the user equipment after being radiated by a transmitter, or is received by the user equipment after being reflected by the intermediate node device, and the method comprises the following steps:
step 101, transmitting indication information of the beam direction of the intermediate node through downlink information, where the downlink information includes first indication information for identifying the beam direction of the intermediate node.
One of the schemes of the application is as follows: the downlink information includes second indication information, and the second indication information includes a random access channel resource and a random access preamble sequence corresponding to the beam direction of the intermediate node. Further, the downlink information includes third indication information, and the third indication information includes a corresponding relationship between a downlink SSB transmission block or a CSI-RS corresponding to the beam direction of the intermediate node.
Preferably, the downlink information is a higher layer signaling (RRC signaling or MAC CE signaling); the downlink information includes at least one of the following information: mapping pattern period, SSB random access opportunity and intermediate node phase information. Optionally, the downlink information may also be DCI signaling.
Another technical solution of the present application is that the first indication information includes all beam directions within a phase change period of the intermediate node.
At this time, the downlink information may also be sent in a broadcast manner. For example, the first indication information is configured by a terminal-specific higher layer signaling or by a common higher layer signaling; for another example, the first indication information terminal is configured by dedicated downlink control signaling or configured by group common signaling.
And 102, in the beam failure recovery process, switching to the beam direction indicated in the downlink information.
When the first indication information contains all beam directions within the phase change period of the intermediate node, the terminal device can automatically select another beam dedicated to the intermediate node when the current beam fails.
When the first indication information only comprises one beam direction dedicated to the intermediate node and the corresponding random access channel resource and random access preamble sequence, and the terminal equipment fails in the current beam, the request network further indicates another beam direction dedicated to the terminal equipment and dedicated to the intermediate node and the corresponding random access channel resource so as to switch to another beam dedicated to the intermediate node.
In the embodiments of fig. 3 to 4, in the system with the intermediate node, the base station schedules a part of terminals to transmit data after being reflected by the intermediate node, when the part of terminals detect a beam failure, the base station configures a reference signal for determining a new beam, the terminal detects the reference signal to obtain new beam information, and the terminal receives an uplink random access resource and an uplink random access sequence, which are configured by the base station and are dedicated for beam failure recovery of the intermediate node system. The method is different from the uplink random access resource and the uplink random access sequence which are not provided with the intermediate node, so as to avoid collision caused when the terminal which does not reflect the received signal through the intermediate node but directly receives the base station signal carries out beam recovery.
Fig. 3 is a flowchart of an embodiment of the method of the present invention applied to a network device.
The method in the embodiment of the first aspect of the present application, applied to a network device, includes the following steps:
step 201A, the network device receives a beam switching request, where the beam switching request requires to indicate a beam direction dedicated to an intermediate node.
Step 202A, the network device sends the downlink information, which includes first indication information, second indication information, and third indication information.
The first indication information is used for identifying the beam direction of the intermediate node; the second indication information comprises random access channel resources and random access preamble sequences corresponding to the beam direction of the intermediate node; the third indication information includes a corresponding relationship of a downlink SSB transmission block or a CSI-RS corresponding to the intermediate node beam direction.
Mode 1: the phase change of the intermediate node is periodic, and the downlink information is indicated by RRC signaling or MAC CE signaling. For example, information such as an Association pattern period (Association pattern period) and an SSB access timing (SSB-perRACH-occasion) is added to RRC or MAC CE signaling.
Mode 2: the phase change of the intermediate node is at the time slot level, and the downlink information is indicated by DCI signaling. Considering that DCI signaling overhead is large, the number of mappings between random access occasions and SSB blocks may be reduced. If the terminal configures the CSI-RS for new beam measurement and beam management, terminal-specific signaling is needed to indicate a mapping period and a mapping relationship between the CSI-RS and a random access time, so as to specify an RACH opportunity where a dedicated preamble is located within a certain time range.
Fig. 4 is a flowchart of an embodiment of the method of the present invention applied to a terminal device.
The method in the embodiment of the first aspect of the present application is applied to a terminal device, and includes the following steps:
step 301A, the terminal device receives the downlink information, which includes first indication information, second indication information, and third indication information.
The first indication information is used for identifying the beam direction of the intermediate node; the second indication information comprises random access channel resources and random access preamble sequences corresponding to the beam direction of the intermediate node; the third indication information includes a corresponding relationship of a downlink SSB transmission block or a CSI-RS corresponding to the intermediate node beam direction.
Step 302A, the terminal device performs beam switching according to the beam direction indicated by the downlink information when the current beam fails.
For example, the terminal receives second indication information configured by the terminal, where the second indication information is a random access channel resource and a random access preamble sequence dedicated by the intermediate node and used for beam failure recovery, and the second indication information is configured by the terminal-specific signaling.
Further, third indication information received by the terminal is the terminal-specific signaling indication, and the third indication information is a beam correspondence relationship between each random access channel and the preamble sequence and an SSB transport block or a CSI-RS of the base station.
Fig. 5 is a schematic view of an SSB reflective communication application scenario.
It should be noted that the phase of the intermediate node is dynamically adjusted by the base station to better implement coverage and the like, so the beam direction of the SSB block after the dynamic adjustment of the phase is rotated, and the correspondence between the random access timing (RO) composed of the existing random access resource and the random access sequence and the SSB block is not applicable, so the base station notifies the mapping period of the SSB and the RACH and the mapping relationship between the SSB and the random access timing to the terminal. Considering that the phase of the intermediate node is dynamically changed, the signaling of the mapping period and the mapping relation can no longer broadcast the indication through the system information, and needs to be indicated to the terminal through the terminal-specific signaling.
Fig. 6 is a flowchart of another embodiment of the method of the present invention applied to a network device.
The method in the embodiment of the first aspect of the present application, applied to a network device, includes the following steps:
step 201B, the network device sends the downlink information, where the downlink information includes first indication information, and the first indication information includes all beam directions within a phase change period of an intermediate node;
the base station indicates the dynamically changed phase to the terminal by signaling, considering that the phase of the intermediate node is dynamically adjusted by the base station for better coverage and the like, the beam direction of the SSB block after the dynamic adjustment of the phase is rotated, and considering that the phase of the intermediate node is dynamically changed.
Step 202B, the network device receives the beam switching request, and identifies the switched beam direction.
Fig. 7 is a flowchart of another embodiment of the method of the present invention applied to a terminal device.
The method in the embodiment of the first aspect of the present application is applied to a terminal device, and includes the following steps:
step 301B, the terminal device receives the downlink information, where the downlink information includes first indication information, where the first indication information is used to identify a beam direction of an intermediate node, and the first indication information includes all beam directions within a phase change period range of the intermediate node;
in step 301B or other steps, the terminal device receives an existing uplink random access resource and an uplink random access sequence for beam failure, and in step 301B, the terminal receives configured first indication information, generally, the first indication information is phase information of an intermediate node, for example:
mode 1: the phase change of the intermediate node is periodic and indicated by RRC signaling or MAC CE signaling. The phase information of the intermediate node is added in RRC or MAC CE signaling.
Mode 2: the method is used for sending the similar broadcast information to the terminal, and is suitable for judging the condition that a plurality of terminals need to know the phase information according to the beam failure request reported by the terminal. After receiving the beam failure requests reported by the multiple terminals, the base station periodically sends a high-level public signaling indication to the phase of the intermediate node of the multiple terminals.
Mode 3: the phase change of the intermediate node is slot level, indicated with DCI signaling. Considering that DCI signaling overhead is large, the phase information of the intermediate node is quantized and indicated by the quantized bits. If the indication needs to be given to a plurality of terminals, the indication can be carried out by defining a downlink control signaling scrambled by phase-RNTI and sampling group signaling, and the phase information is indicated to a group of terminals at the same time, so that the signaling overhead is reduced.
Step 302B, when the current beam fails, the terminal device selects a new beam direction within the range of all beam directions to perform beam switching.
And the terminal calculates the rotation direction of the SSB block or the CSI-RS wave beam according to the obtained intermediate node phase information and recovers the wave beam by utilizing the corresponding random access time.
For example, the base station configures 64 SSB blocks or CSI-RS beam directions, the terminal measures the best beam direction as the fourth beam direction, obtains the best corresponding SSB block or CSI-RS beam direction that has not been reflected by the intermediate node as the first beam according to the intermediate node phase information, and performs access at the random access time mapped by the first SSB block or CSI-RS beam. The base station knows that the optimal downlink beam reported by the terminal is the first beam according to the information of the random access time, and then sends the first beam in the subsequent transmission
