Description
Technical Field
The invention relates to the technical field of wireless technology, in particular to a method and a device for managing an orbital angular momentum mode and a base station.
Background
Aiming at the problem that the coverage area of a base station is limited during high-frequency transmission, an access backhaul integrated (Integrated Access and Backhaul, IAB) technology is generally adopted at present, the signal coverage area is improved by using a relay transmission mode, and the backhaul function is added on the basis of meeting the access function of the base station.
In addition, the current IAB technology mainly adopts a Time-division multiplexing (Time-division multiplexing, TDM) mode, that is, when the IAB node is used as a traditional base station to communicate with the terminal UE, the IAB node is not used as a backhaul link to communicate with other IAB nodes.
In the IAB technology, the capacity of the overall network is strongly related to the capacity of the backhaul link, and it is considered that the spectral efficiency of the backhaul link is improved by adopting the orbital angular momentum (Orbital Angular Momentum, OAM) technology. The electromagnetic wave carrying the orbital angular momentum has the characteristic of hollow divergence, the whole wave beam presents a hollow inverted cone shape, and the radius of the annular wave beam is larger and larger along with the increase of the transmission distance; and the larger the modal value, the more divergent. Therefore, by using a specific OAM antenna, the rank of the equivalent channel is increased by changing the form of the transmit antenna (equivalently, increasing the space between the transmit antennas and reducing the correlation of the LoS channel), and the multi-stream parallel transmission is performed, thereby achieving the effect of improving the capacity.
However, when the OAM technology is applied to the backhaul link, if the diameters of the receiving ring arrays of the IAB nodes at different distances from the host Donor base station are all the same, if the Donor base station transmits the beam of the same mode to the different IAB nodes, the IAB node at a far distance cannot receive the complete mode information due to the divergence of the beam, thereby affecting the performance.

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The orbital angular momentum mode management method provided by the embodiment of the invention is applied to a wireless communication system adopting an IAB technology. Fig. 1 is a schematic diagram of a wireless communication system adopting a mode management method according to an embodiment of the present invention. Wherein the wireless communication system comprises:
host base station/node (IAB node): i.e. an anchor point with a fiber connection core network, such as shown in fig. 1, in the embodiment of the present invention, the host base station/node (IAB node) is DgNB.
IAB node (IAB node): no optical fiber connection and core network, but may be passed back over a wireless link and may provide access functions such as IAB1 and IAB2 in fig. 1.
Wherein, the previous-hop node of a certain IAB node is a parent node, for example, dgNB in fig. 1 is a parent node of IAB 1; the next-hop node of a certain IAB node is a child node, for example, IAB2 in fig. 1 is a child node of IAB 1; the link between the terminal UE and the IAB node or IAB donor is an access link, which includes an uplink access link and a downlink access link, such as links 1a, 2a, and 3 in fig. 1; the links between the IAB node and the IAB child node or the IAB parent node are backhaul links, which include an uplink backhaul link and a downlink backhaul link, such as links 1b and 2b in fig. 1.
In order to improve the capacity Of a return link Of a direct-view path (LOS) in an IAB technology, the wireless communication system adopting the mode management method according to the embodiment Of the invention utilizes an orbital angular momentum OAM technology to improve the spectrum efficiency Of the return link.
Specifically, electromagnetic waves of a beam transmitted by using orbital angular momentum OAM technology add a phase rotation factor exp (jlΦ) compared to normal electromagnetic waves, in this way, the beam carrying OAM will no longer be a planar structure but will rotate around the beam propagation direction.
Wherein, beam amplitude U carrying OAMCan be expressed as:
wherein A (r) represents the amplitude of electromagnetic wave with a planar structure, and r represents the radiation distance of the central axis of the wave beam;for azimuth, l represents an eigenvalue of OAM, which may also be referred to as a modal value or order.
The characteristic of OAM makes the equiphase surface of electromagnetic wave take the form of spiral along the propagation direction, and the phase change is 2 pi l after one revolution. When l=0, the electromagnetic wave does not have vortex characteristics, namely the traditional plane wave.
In addition, electromagnetic vortex waves of different modes l are mutually orthogonal, and OAM vortex waves of different mode values can be transmitted in parallel in the same bandwidth.
Based on the characteristics, the electromagnetic wave carrying orbital angular momentum has the characteristic of hollow divergence, the whole wave beam presents a hollow inverted cone shape, and the radius of the annular wave beam is larger and larger along with the increase of the transmission distance; the larger the modal value, the larger the electromagnetic wave divergence.
When the OAM is applied to the backhaul link of the IAB technology, if the diameters of the receiving circular arrays of the IAB nodes at different distances from the host Donor base station are the same, as shown in fig. 2, if the Donor base station sends a beam of the same mode to different IAB nodes, the IAB node at a far distance cannot receive the complete mode information due to the divergence of the beam. In order to solve the problem, the embodiment of the invention provides a mode determining method, which is characterized in that a Donor base station sends reference signals of different modes, an IAB node measures channel quality aiming at the reference signals of different modes and reports the reference signals to the Donor base station, so that the Donor base station can distribute communication modes according to the channel quality reported by the IAB node, and the IAB node can be ensured to receive beams in an optimal mode, thus improving the system capacity and adopting beams of different modes aiming at the IAB node at different positions at the same time, and achieving the purpose of improving the system efficiency.
Specifically, the method for managing a modality according to one embodiment of the present invention is applied to an IAB node, as shown in fig. 3, and includes:
s310, receiving at least two reference signals with different modes sent by a host base station;
S320, reporting measurement result information of at least one reference signal;
s330, receiving the mode information of the communication with the IAB node, which is determined by the host base station according to the measurement result information.
By adopting the mode management method in the embodiment, the host base station can determine the optimal mode for communication with the IAB node according to the measurement result information reported by the IAB node, so that the IAB node can acquire complete mode information when receiving the wave beam by adopting the optimal mode, and therefore, the effect of improving the system efficiency is achieved on the basis of improving the system capacity.
In the embodiment of the invention, the measurement result information reported by the IAB node comprises the identity information and the signal quality information of the reference signal.
Optionally, the signal quality information includes at least one of a reference signal received power (Reference Signal Receiving Power, RSRP), a reference signal received quality (Reference Signal Receiving Quality, RSRQ), and a signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR).
Optionally, the identity information of the reference signal includes mode information corresponding to the reference signal.
In the embodiment of the present invention, in step S310, receiving at least two reference signals with different modalities sent by a host base station includes:
Receiving at least two reference signals with different modes sent by a host base station at the same moment; or alternatively
Receiving at least two reference signals with different modes sent by a host base station at different moments; wherein, the sending time of the reference signals of different modes is different.
Specifically, the host base station transmits the reference signals corresponding to different modes respectively, wherein the transmission mode of the reference signals includes but is not limited to periodic, semi-continuous or non-periodic. In addition, the reference signals are cell-level, i.e. the configurations of the reference signals of different IAB nodes for the same modality are the same.
When the host base station transmits the reference signals, each mode corresponds to one reference signal, and different reference signals can be identified by different identity information.
In one embodiment, when the host substrate transmits reference signals with different modes at the same time, an IAB node receiving the reference signals is required to have a higher demultiplexing capability.
In another embodiment, when the host base station transmits reference signals of one mode respectively at each time, each IAB node may acquire each reference signal transmitted by the host base station at a different time, and measure the reference signals of different modes to acquire signal quality information, for example, RSRP.
In the embodiment of the present invention, optionally, in step S320, reporting measurement result information of at least one reference signal includes:
reporting the measurement result information of each reference signal; or alternatively
Reporting measurement result information of a reference signal with signal quality meeting preset conditions; or alternatively
Reporting the measurement result information of the reference signals with the signal quality meeting the preset quantity of preset conditions.
In one embodiment, in step S320, the IAB node reports measurement result information of the acquired reference signals of each mode;
in another embodiment, in step S320, the IAB node screens reference signals with signal quality according to the acquired reference signals of each mode, and reports measurement result information of the screened reference signals with signal quality according to the preset conditions, for example, reports measurement result information of the reference signals with signal quality reaching the preset value;
in still another embodiment, in step S320, the IAB node screens the reference signals with signal quality according to the acquired reference signals of each mode, and selects a preset number from the screened reference signals, and reports the measurement result information of the preset number of reference signals with signal quality according to the preset condition, for example, when the reported signal quality reaches a preset value and the signal quality is arranged from high to low, the measurement result information of the preset number of reference signals arranged in the first few bits is displayed.
The specific reporting mode of the measurement result information can be configured by the host base station or agreed by a protocol between the IAB node and the host base station.
For example, when three IAB nodes exist, as shown in fig. 4a to fig. 4c, by adopting the mode determining method according to the embodiment of the present invention, the host base station may send reference signals of three modes at three moments, and each IAB node measures the reference signal of each mode, where the measurement result may be as shown in the following table 1:
TABLE 1
According to the measurement result information, each IAB node reports the measurement result information (including the identity information and the signal quality of the reference signal, for example, RSRP) to the host base station, for example, each IAB node reports the RSRP of the two reference signals with the best RSRP. For IAB node 1, reporting RS1 (-80) and RS2 (-100); for IAB node 2, reporting RS2 (-80) and RS1 (-90); for IAB node 3, RS3 (-80) and RS1 (-85) are reported.
Optionally, in step S320, reporting measurement result information of at least one reference signal includes:
reporting measurement result information of at least one reference signal at a preset time;
the preset time is configured by the host base station.
Optionally, the preset time is semi-statically configured by the host base station.
In the embodiment of the present invention, the host base station determines the mode of communication with each IAB node according to the measurement result information reported by each IAB node.
Specifically, when there are multiple IAB nodes in the system, there may be the same reference signal corresponding to the maximum RSRP reported by the multiple nodes, and the host base station needs to comprehensively consider orthogonality at this time, avoid mutual interference between beams of the IAB nodes in the determined mode, and select the best mode for each IAB node host base station. Such as: reporting RS1 (-80) of the mode 1 and RS2 (-85) of the mode 2 to the IAB node 1; IAB node 2 reports RS1 (-80) of mode 1 and RS2 (-82) of mode 2; IAB node 3 reports RS3 (-80) of modality 3 and RS1 (-85) of modality 1; the host base station comprehensively considers orthogonality, and determines that the optimal mode of the IAB node 1 (i.e. the communication mode) is the mode 1, the optimal mode of the IAB node 2 (i.e. the communication mode) is the mode 2, and the optimal mode of the IAB node 3 (i.e. the communication mode) is the mode 3.
Based on the above manner, when the host base station determines the best mode of each IAB node, and when the modes of the reference signals corresponding to the RSRP reported by each IAB node are different, respectively selecting the corresponding mode with the best reported RSRP for each IAB node; when the modes of the reference signals corresponding to the RSRP best reported by the IAB nodes are the same, the orthogonality is considered, the best mode of the IAB nodes is comprehensively determined, the beams of the IAB nodes of the determined modes cannot interfere with each other, and the better mode of each IAB node is respectively obtained as a selection principle.
In the method for managing a mode according to the embodiment of the present invention, after receiving the mode information of communication with the IAB node determined by the host base station according to the measurement result information in step S330, the method further includes:
a beam having the communication modality is received.
Specifically, each IAB node receives a channel/signaling of subsequent control, data, etc. for a best mode assigned by the host base station based on the best mode.
By adopting the mode management method provided by the embodiment of the invention, the IAB nodes at different positions can be communicated by adopting the beams of different modes, and the system efficiency can be improved while the system capacity under the LOS condition is improved.
The embodiment of the invention also provides a method for managing the orbital angular momentum mode, which is applied to the host base station, as shown in fig. 5, and comprises the following steps:
