Description

Orbital angular momentum mode management method, device and base station

Technical Field

The present invention relates to the field of wireless technologies, and in particular, to a method, an apparatus, and a base station for orbital angular momentum mode management.

Background

For the problem of limited coverage of the base station during high frequency transmission, an Access and Backhaul (IAB) technology is usually adopted at present, the coverage of the signal is improved by using a relay transmission mode, and a 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 (TDM) mode, that is, when the IAB node is used as a traditional base station to communicate with a terminal UE, the IAB node does not serve as a backhaul link to communicate with other IAB nodes.

In the IAB technology, the capacity of the entire network is strongly related to the capacity of the backhaul link, and it is currently considered to improve the spectrum efficiency of the backhaul link by using an Orbital Angular Momentum (OAM) technology. The electromagnetic wave carrying orbital angular momentum has the hollow divergence characteristic, the whole wave beam is in 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 transmit antenna state (equivalently, increasing the transmit antenna spacing and reducing the correlation of the LoS channel), and 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, without loss of generality, if the diameters of the receiving circular ring arrays of the IAB nodes at different distances from the Donor base station are all the same, if the Donor base station sends a beam of the same mode to different IAB nodes, the distant IAB nodes will not receive complete mode information due to the divergence of the beam, thereby affecting performance.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

The orbital angular momentum mode management method 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 invention. Wherein the wireless communication system comprises:

host base station/node (IAB node): that is, an anchor point with an optical fiber connected to a core network, for example, as shown in fig. 1, in the embodiment of the present invention, an anchor base station/node (IAB node/node) is DgNB.

IAB node (IAB node): there is no fiber connection and core network, but backhaul can be via wireless links, and nodes that can provide access functions, such as IAB1 and IAB2 in fig. 1.

Wherein, a 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; a 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; a link between the terminal UE and the IAB node or the IAB node is an access link, and the access link includes an uplink access link and a downlink access link, such as

links

1a, 2a, and 3 in fig. 1; the link between the IAB node and the IAB child node or the IAB parent node is a backhaul link, which includes 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) path in the IAB technology, the wireless communication system adopting the mode management method in the embodiment Of the present invention utilizes the orbital angular momentum OAM technology to improve the spectrum efficiency Of the return link.

Specifically, the electromagnetic wave of the beam is transmitted by adopting the orbital angular momentum OAM technology, and compared with the normal electromagnetic wave, a phase rotation factor exp (jl phi) is added, and based on the mode, the beam carrying the OAM is not a plane structure any more, but rotates around the propagation direction of the beam.

Wherein, the wave beam amplitude U carrying OAM

Can be expressed as:

wherein A (r) represents the amplitude of the electromagnetic wave in a plane structure, and r represents the radiation distance of the central axis of the wave beam;

for azimuth, l represents the eigenvalue of the OAM, which may also be referred to as modal value or order.

The OAM characteristics make the equiphase surface of the electromagnetic wave in a spiral form along the propagation direction, and the phase changes by 2 pi l after one rotation. When l is 0, the electromagnetic wave has no vortex characteristic, i.e. is a conventional plane wave.

In addition, the 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 hollow divergence characteristic, the whole wave beam is in 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; when the modal value is larger, the electromagnetic wave divergence is larger.

When OAM is applied to the backhaul link of the IAB technology, if the diameters of the receiving circular ring arrays of the IAB nodes at different distances from the Donor base station are all the same, as shown in fig. 2, if the Donor base station sends a beam of the same mode to different IAB nodes, the distant IAB nodes will not receive complete mode information due to the divergence of the beam. In order to solve the problem, embodiments of the present invention provide a mode determining method, where reference signals of different modes are sent by a Donor base station, and an IAB performs channel quality measurement on the reference signals of different modes and reports the measured channel quality to the Donor base station, so that the Donor base station can perform communication mode allocation according to the channel quality reported by the IAB, and ensure that the IAB can perform beam reception in the best mode, so that when system capacity is improved, different modes of beams can be used for IAB nodes at different positions, and a purpose of improving system efficiency is achieved.

Specifically, the modality management method according to an embodiment of the present invention is applied to an IAB node, and as shown in fig. 3, the method includes:

s310, receiving at least two reference signals with different modes sent by a host base station;

s320, reporting the measurement result information of at least one reference signal;

and S330, receiving modal information of 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 of communication with the IAB node according to the measurement result information reported by the IAB node, so as to ensure that the IAB node can acquire complete mode information when performing beam receiving in the optimal mode, thereby achieving the effect of improving the system efficiency 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 Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR).

Optionally, the identity information of the reference signal includes modality information corresponding to the reference signal.

In this embodiment of the present invention, in step S310, receiving at least two reference signals with different modalities sent by a donor base station includes:

Specifically, the donor base station respectively transmits the reference signals corresponding to different modalities, where the transmission manner of the reference signals includes, but is not limited to, periodic, semi-persistent, or non-periodic. In addition, the reference signals are cell-level, that is, different IAB nodes have the same configuration for reference signals of the same modality.

When the host base station sends the reference signal, each mode corresponds to one reference signal, and different reference signals can adopt different identity information identifiers.

In one embodiment, when the host substrate transmits reference signals with different modes at the same time, the IAB node receiving the reference signals is required to have a high demultiplexing capability.

In another embodiment, when the donor base station respectively and correspondingly sends a reference signal in one mode at each time, each IAB node may obtain each reference signal sent by the donor base station at different times, perform measurement corresponding to the reference signals in different modes, and obtain signal quality information, for example, RSRP.

In this embodiment of the present invention, optionally, in step S320, reporting measurement result information of at least one of the reference signals includes:

reporting the measurement result information of each reference signal; or

In one embodiment, in step S320, the IAB node reports measurement result information of the acquired reference signal of each mode;

in another embodiment, in step S320, the IAB node selects, according to the obtained reference signal of each mode, a reference signal whose signal quality meets a preset condition, and reports measurement result information of the selected reference signal whose signal quality meets the preset condition, for example, reports measurement result information of the reference signal whose signal quality reaches a preset value;

in another embodiment, in step S320, the IAB node selects, according to the obtained reference signals of each mode, reference signals whose signal quality meets a predetermined condition, selects a predetermined number from the selected reference signals, and reports measurement result information of the predetermined number of reference signals whose signal quality meets the predetermined condition, for example, the measurement result information of the predetermined number of reference signals arranged in the first several bits when the reported signal quality reaches the predetermined value and the signal quality is arranged from high to low.

The specific way of reporting the measurement result information may be configured by the host base station, or agreed by a protocol between the IAB node and the host base station.

For example, when there are three IAB nodes, as shown in fig. 4a to 4c, by using the mode determination method according to the embodiment of the present invention, the donor base station may send reference signals of three modes at three times, and each IAB node measures the reference signal of each mode, where the measurement result may be as shown in table 1 below:

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 RSRP of two reference signals with the best RSRP. For the IAB node 1, reporting RS1(-80) and RS2 (-100); for the 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 of the reference signals includes:

and the preset time is configured by the host base station.

Optionally, the preset time is configured semi-statically by the host base station.

In the embodiment of the present invention, according to the measurement result information reported by each IAB node, the host base station determines the mode of communication with each IAB node.

Specifically, when a plurality of IAB nodes exist in the system, it may exist that reference signals corresponding to the maximum RSRP reported by the plurality of nodes are the same, and at this time, the host base station comprehensively considers orthogonality, avoids mutual interference between beams of the IAB nodes in the determined mode, and selects the best mode for each IAB node host base station. Such as: for the IAB node 1, reporting RS1(-80) of the mode 1 and RS2(-85) of the mode 2; IAB node 2 reports RS1(-80) of mode 1 and RS2(-82) of mode 2; IAB node 3 reports RS3(-80) of mode 3 and RS1(-85) of mode 1; the host base station comprehensively considers the orthogonality, and determines that the optimal mode (i.e., communication mode) of the IAB node 1 is mode 1, the optimal mode (i.e., communication mode) of the IAB node 2 is mode 2, and the optimal mode (i.e., communication mode) of the IAB node 3 is 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 best RSRP reported by each IAB node are different, the host base station selects the corresponding mode with the best reported RSRP for each IAB node; and when the modes of the reference signals corresponding to the optimal RSRP reported by the IAB nodes are the same, considering orthogonality, comprehensively determining the optimal modes of the IAB nodes, and taking the selection principle that the beams of the IAB nodes in the determined modes cannot interfere with each other and the optimal mode of each IAB node is obtained respectively.

In the mode management method according to the embodiment of the present invention, after receiving the mode information of communicating with the IAB node, which is determined by the host base station according to the measurement result information, in step S330, the method further includes:

receiving a beam having the communication modality.

Specifically, each IAB node receives subsequent control, data, etc. channels/signaling based on the optimal modality assigned by the donor base station for the optimal modality.

and S540, sending the modal information to the IAB node.

By adopting the mode management method of the embodiment of the invention, the host base station can communicate with the IAB according to the measurement result information reported by the IAB so as to ensure that the IAB can obtain complete mode information when adopting the optimal mode to carry out beam receiving, thereby achieving the effect of improving the system efficiency on the basis of improving the system capacity.
