Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to a polarization type information broadcasting method and device, a base station and a terminal. BACKGROUND

[0002] In multiple cells or beams, adjacent cells or adjacent beams use different polarization manners, which can reduce the interference between adjacent cells or adjacent beams. In this scenario, the terminal needs to know the polarization manner used in a specific cell or beam.

[0003] Reflections in buildings, landscapes, and water can weaken polarization before it reaches the user equipment (UE). If a satellite receiving device (receiving UE) receives a radio wave reflected in a window at the Brewster angle, the polarization component that aligns with the direction of the radio wave is canceled out. Even if the signal is circularly polarized at the transmitting end, the receiving UE will only observe linearly polarized waves, or even the opposite polarization type, so the receiving UE cannot determine the polarization type used by the satellite, resulting in unexpected attempts and interference.

[0004] In addition, if there is a terminal with a linearly polarized antenna in the network that can receive both linearly polarized signals and circularly polarized signals, it cannot distinguish the polarization manner of the signal through the received signal itself, and if the terminal cannot obtain the polarization type information indication, it will destroy the polarization multiplexing effect expected by the network.

[0005] Therefore, in order to realize polarization multiplexing between beams or cells, the network needs to indicate the polarization type information of the beam or cell to the terminal through explicit signaling information. SUMMARY

[0085] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in detail below with reference to the drawings and specific embodiments.

[0086] The present application provides a polarization type information broadcasting method, device, base station and terminal in order to solve the problem that the polarization multiplexing between beams or cells is difficult to be normally performed in the prior art.

[0087] Firstly, the concept of polarization multiplexing in the embodiment of the present application is described. Figure 1As shown, the base station sends a message to UE 1 in a beam of a left-hand circular polarization (LHCP) type, sends a message to UE 2 in a beam of a right-hand circular polarization (RHCP) type, and sends a message to UE 3 in a beam of a left-hand circular polarization (LHCP) type, that is, sends a message to UE 1 and sends a message to UE 3 in beams of a LHCP type, that is, polarization multiplexing of beams of a LHCP type is achieved.

[0088] Optionally, Figure 1 The base station in the method can be a base station gNB or a satellite.

[0089] As Figure 2 As shown, an embodiment of the present application provides a polarization type information broadcasting method applied to a base station, and the method comprises the following steps:

[0090] Step 201: broadcast a system message; wherein the system message comprises polarization type information, and the polarization type information is used to indicate a polarization type of a beam of the base station sending the system message or a cell sending the system message.

[0091] It should be noted that the base station provided by the embodiment of the present application includes but is not limited to a base station gNB and / or a satellite, and in the embodiment of the present application, the base station is taken as a satellite for example.

[0092] In the embodiment of the present application, the base station broadcasts a system message carrying polarization type information to a terminal, and the polarization type information is used to indicate a polarization type of a beam of the base station sending the system message or a cell sending the system message, thereby solving the problem of incorrect connection of the terminal due to the fact that the base station does not broadcast polarization type, and further ensuring that polarization multiplexing between beams or cells of network configuration is normally performed.

[0093] Optionally, the broadcasting of the system message comprises the following steps:

[0094] The system message is broadcast in a single polarization mode;

[0095] Or,

[0096] The system message is broadcast in a polling polarization mode.

[0097] It should be noted that, when the polarization mode of the terminal does not match the polarization type of the beam or cell, for example, the polarization type of the terminal is LHCP type, but the polarization type of the satellite beam is RHCP type, the terminal cannot receive the system message sent by the beam of RHCP type, which causes the polarization type information broadcast by the base station to be difficult to perform, therefore, in the embodiment of the application, the satellite can adopt two modes for polarization broadcast, one mode is a single mode, that is, the system message is broadcast and sent by a single polarization mode, and the other mode is a polling mode, that is, the system message is broadcast and sent by a polling polarization mode, one of the two implementation modes is selected, so that the terminal with mismatched polarization type does not occur error connection, reduces the waste of time-frequency resources and energy of the satellite, and also reduces the waste of energy and time of the terminal.

[0098] Further, the system message is broadcast and sent by a single polarization mode, comprising:

[0099] In the beam or cell of the left-handed polarization type, the system message is broadcast and sent by one of the left-handed polarization mode or the linear polarization mode;

[0100] In the beam or cell of the right-handed polarization type, the system message is broadcast and sent by one of the right-handed polarization mode or the linear polarization mode.

[0101] Specifically, when the polarization broadcast is performed by the single mode, in the beam or cell of the LHCP type, the satellite adopts one of the LHCP polarization mode or the linear polarization mode to send the system message; in the beam or cell of the RHCP type, the satellite adopts one of the RHCP polarization mode or the linear polarization mode to send the system message.

[0102] Further, the system message is broadcast and sent by a polling polarization mode, comprising one of the following:

[0103] The system message is broadcast and sent by polling in three polarization modes of the left-handed polarization mode, the right-handed polarization mode and the linear polarization mode;

[0104] The system message is broadcast and sent by polling in two polarization modes of the left-handed polarization mode and the right-handed polarization mode;

[0105] The system message is broadcast and sent by polling in two polarization modes of the linear polarization mode and a first polarization mode; the first polarization mode is the left-handed polarization mode or the right-handed polarization mode.

[0106] Specifically, when performing polarized broadcasting through the polling mode, the satellite adopts three polarization modes of LHCP polarization mode, RHCP polarization mode and linear polarization mode to poll and send system messages; or, the satellite adopts two polarization modes of LHCP polarization mode and RHCP polarization mode to poll and send system messages; or, the satellite adopts two polarization modes of linear polarization mode and LHCP polarization mode to poll and send system messages; or, the satellite adopts two polarization modes of linear polarization mode and RHCP polarization mode to poll and send system messages.

[0107] Preferably, when performing polarized broadcasting through the polling mode, under the beam or cell of the LHCP type, the satellite adopts two polarization modes of linear polarization mode and LHCP polarization mode to poll and send system messages; and under the beam or cell of the RHCP type, the satellite adopts two polarization modes of linear polarization mode and RHCP polarization mode to poll and send system messages.

[0108] Optionally, the polarization type information is included in a Master Information Block (MIB) message of the system message, or the polarization type information is included in a first System Information Block (SIB) message of the system message.

[0109] In the embodiment of the present application, the feasible carrier carrying the polarization type information can be a Master Information Block (MIB) message of the system message, or a first System Information Block (SIB) message in the SIB of the system message, that is, the polarization type information is added in the MIB message of the system message, or the polarization type information is added in the first SIB message of the system message.

[0110] It should be further noted that, when performing polarized broadcasting through the polling mode, the polling cycle is combined with the cycle standard of the MIB message / SIB message.

[0111] Optionally, in the case of including the polarization type information in the MIB message, the method further comprises:

[0112] adding the polarization type information in a spare field in the MIB message.

[0113] It should be noted that the specific scheme of adding the polarization type information in the MIB message of the system message is that, in the MIB message specified in the 38.331-5.2.1 protocol and the 38.213-4.1 protocol of the 5G NR, the polarization type information is added in the spare field of 1 bit space, and the specific signaling rewriting is as follows:

[0114]

[0115]

[0116] In the signaling described above, LHCP represents that the satellite beam is a left-hand polarized type beam; RHCP represents that the satellite beam is a right-hand polarized type beam.

[0117] Optionally, in the case that the polarization type information is included in the first SIB message, the first SIB message is one of a plurality of SIB messages currently broadcast by the base station;

[0118] Or,

[0119] The first SIB message is an SIB message other than the plurality of SIB messages currently broadcast by the base station.

[0120] In the embodiment of the present application, the type of the first SIB message including the polarization type information is not limited, the first SIB message can be one of the plurality of SIB messages currently broadcast by the base station, that is, one of the plurality of SIB messages currently broadcast by the base station, preferably, the first SIB message is an SIB 1 message, the first SIB message can also be a newly defined SIB message other than the plurality of SIB messages currently broadcast by the base station, that is, an added SIB message other than the plurality of SIB messages currently broadcast by the base station.

[0121] Optionally, in the case that the polarization type information is included in the first SIB message, the method further comprises:

[0122] Adding the polarization type information in the first SIB message;

[0123] The field type of adding the polarization type information is one of the following:

[0124] Enumeration type;

[0125] Bit stream type;

[0126] Integer type.

[0127] Specifically, the field of adding the polarization type information in the first SIB message can be an enumeration type field, a bit stream type field, or an integer type field, preferably, the field of adding the polarization type information in the first SIB message is an enumeration type field.

[0128] The enumeration type field of adding the polarization type information in the first SIB message is specifically:

[0129] SIB::=SEQUENCE{

[0130] polarization-parameters ENUMERATED{type1,type2}, ...

[0132] }OPTIONAL,

[0133]

[0134] The bit stream type field of the polarization type information added in the first SIB message is specifically as follows:

[0135] SIB ::= SEQUENCE {

[0136] polarization-parameters polarization-type, ...

[0138] } OPTIONAL,

[0139] polarization-type ::= BIT STRING (SIZE (1))

[0140]

[0141] The integer type field of the polarization type information added in the first SIB message is specifically as follows:

[0142] SIB ::= SEQUENCE {

[0143] polarization-parameters INTEGER (0..maxpolarization-parameter)

[0144] OPTIONAL, ...

[0146] } OPTIONAL,

[0147]

[0148] Wherein, maxpolarization-parameter is the total number of optional polarization types minus 1.

[0149] It should be further pointed out that the correspondence between the polarization parameters and the polarization types in the above signaling can be freely arranged and combined, but the method of changing the signaling remains unchanged.

[0150] The polarization type information broadcasting method provided by the embodiment of the present application can successfully broadcast the polarization type of the beam or the cell to the terminal by broadcasting the system message carrying the polarization type information, and the polarization type information is used to indicate the polarization type of the beam or the cell of the base station sending the system message, thereby solving the problem of the terminal incorrectly connecting due to the base station not broadcasting the polarization type of the beam or the cell, and further ensuring the polarization multiplexing between the beams or cells configured by the network to be normally performed, and the Non-Terrestrial Networks (NTN) scenario proposed to solve the problem is a new scenario.

[0151] As shown in Figure 3 The embodiment of the present application also provides a polarization type information broadcasting method, applied to a terminal, and the method comprises the following steps:

[0152] Step 301: receiving the system message sent by the base station.

[0153] In the embodiment of the present application, after the terminal receives the system message broadcasted by the base station, the terminal starts to blindly detect the synchronization signal block (SSB), detects the primary synchronization signal (PSS) to obtain the Orthogonal Frequency Division Multiplexing (OFDM) symbol boundary synchronization (time domain synchronization) and coarse frequency synchronization (frequency domain synchronization), and further detects the Secondary Synchronization Signal (SSS) to obtain the remaining information of the cell Identity document (ID).

[0154] After the terminal completes the detection of the primary synchronization signal and the secondary synchronization signal, the physical broadcast channel (PBCH) needs to be decoded, wherein the PBCH and the demodulation reference signal are contained in the SSB.

[0155] Step 302: decoding the system message to obtain the polarization type information.

[0156] In this step, the terminal decodes the system message from the physical broadcast channel, and the terminal decodes the polarization type information from the system message.

[0157] Step 303: performing subsequent communication according to the polarization type of the beam or the cell indicated by the polarization type information.

[0158] In other words, after the terminal decodes the polarization type information, it performs subsequent communication based on the polarization type of the beam or cell indicated by the polarization type information.

[0159] In this embodiment of the invention, the terminal receives a system message broadcast by the base station carrying polarization type information. The polarization type information is used to indicate the polarization type of the beam or cell from which the base station sends the system message. This enables the base station to successfully broadcast the polarization type of the beam or cell to the terminal, solving the problem of incorrect terminal connection caused by the base station not broadcasting the polarization type of the beam or cell. This ensures the normal operation of polarization multiplexing between beams or cells configured in the network.

[0160] Optionally, the polarization type information is included in the main system message block (MIB) message of the system message, or the polarization type information is included in the first system message block (SIB) message of the system message;

[0161] When the polarization type information is included in the MIB message, the system message is decoded to obtain the polarization type information, including:

[0162] The MIB message is decoded to obtain the polarization type information;

[0163] If the polarization type information is included in the first SIB message, the system message is decoded to obtain the polarization type information, including:

[0164] The first SIB message is decoded to obtain the polarization type information.

[0165] Specifically, since the polarization type information is carried by the MIB message of the system message, or the polarization type information is carried by the first SIB message of the system message, when the polarization type information is included in the MIB message, the terminal decodes the polarization type information from the MIB message; when the polarization type information is included in the first SIB message, the terminal obtains the first SIB message and decodes the polarization type information from the obtained first SIB message.

[0166] like Figure 4 As shown, this embodiment of the invention provides a polarization-type information broadcasting device applied to a base station, the device comprising:

[0167] The transmitting module 401 is used to broadcast system messages; wherein the system messages include polarization type information, which is used to indicate the beam in which the base station transmits the system messages or the polarization type of the cell transmitting the system messages.

[0195] The communication module 503 is used to perform subsequent communication based on the polarization type of the beam or cell indicated by the polarization type information.

[0196] In this embodiment of the invention, by receiving a system message broadcast by a base station carrying polarization type information, and the polarization type information being used to indicate the polarization type of the beam or cell from which the base station sends the system message, the base station can successfully broadcast the polarization type of the beam or cell to the terminal.
