Abstract

Embodiments of the present disclosure provide a system message processing method and apparatus, a communication device and a storage medium.

Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to a system message processing method and apparatus, communication equipment and storage medium. Background Technology

[0002] In New Radio (NR), system information (SI) messages can be divided into two types according to their broadcast status: periodic broadcasts and aperiodic broadcasts. For connected terminals, if a terminal needs to obtain the second type of SI, it can initiate a request through Radio Resource Control (RRC) layer signaling.

[0003] If the network side has a common search space configured for receiving other system information on the active bandwidth (BWP) where the terminal is operating, the base station can directly broadcast the requested other system information within the common search space of the active BWP, and the terminal can then receive the system message.

[0004] Both the requested system messages and the periodic broadcast system messages are broadcast by the base station. Summary of the Invention

[0005] This disclosure provides a system message processing method and apparatus, a communication device, and a storage medium.

[0006] A first aspect of this disclosure provides a system message processing method, wherein the method is executed by a base station, the method comprising:

[0007] Transmit system messages requesting terminals on a portion of the synchronization signal / physical broadcast channel (PBCH, SS / PBCH) beam.

[0008] A second aspect of this disclosure provides a system message processing method, wherein the method is executed by a terminal, the method comprising:

[0009] The system message requested by the terminal is received on a portion of the SS / PBCH beams.

[0010] A third aspect of this disclosure provides a system message processing apparatus, wherein the apparatus includes:

[0011] The first transmitting module is configured to transmit system messages requesting terminal access on the SS / PBCH beam.

[0012] A fourth aspect of this disclosure provides a system message processing apparatus, wherein the message is executed by a terminal, the apparatus comprising:

[0013] The second receiving module is configured to receive the system message requested by the terminal on a portion of the SS / PBCH beam.

[0014] A fifth aspect of this disclosure provides a communication device, including a processor, a transceiver, a memory, and an executable program stored in the memory and executable by the processor, wherein the processor executes the system message processing method as provided in the first or second aspect above when running the executable program.

[0015] A sixth aspect of this disclosure provides a computer storage medium storing an executable program; the executable program, when executed by a processor, can implement the system message processing method provided in the first or second aspect described above.

[0016] The technical solution provided in this disclosure allows the base station to broadcast the requested SI only on the SS / PBCH beam in the direction of the terminal, rather than broadcasting the SI in all SS / PBCH beam directions. This reduces unnecessary broadcasting of requested system messages and minimizes the time-frequency domain resources consumed by requested system messages. It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the embodiments of this disclosure.

[0030] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several terminals, namely UE11 in the figure, and several access devices 12.

[0031] UE11 can be a device that provides voice and / or data connectivity to a user. UE11 can communicate with one or more core networks via a Radio Access Network (RAN). UE11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE11 can be a device in an unmanned aerial vehicle (UAV). Alternatively, UE11 can be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0032] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0033] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0034] Access device 12 and UE11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0035] like Figure 2 As shown, this disclosure provides a system message processing method, which is executed by a base station. The method includes:

[0036] Step S2001: Transmit a system message requesting the terminal on a portion of the SS / PBCH beams.

[0037] In this embodiment of the disclosure, the method may be performed by a base station. The base station includes, but is not limited to, an eNB and / or a gNB.

[0038] The SS / PBCH is a synchronization broadcast block used by the base station. The SS / PBCH may include: primary synchronization signal, secondary synchronization signal, and PBCH transmission.

[0039] In this embodiment of the disclosure, the SS / PBCH beam is a beam carrying the SS / PBCH. If the base station uses beams to communicate with the terminal, the base station will generally transmit the SS / PBCH on various beams within the cell, so that terminals located at different positions within the cell relative to the base station can establish synchronization with the base station based on the monitored SS / PBCH and access the base station.

[0040] Partial SS / PBCH beams are beams carrying SS / PBCH transmitted by the base station in a specific direction within the cell. This specific direction may include the direction in which the terminal is located.

[0041] For example, a base station may need M beams to transmit SS / PBCH within a cell using beam scanning, but it can transmit system messages requested by the terminal on N SS / PBCH beams, which is less than M.

[0042] A terminal requesting a system message will only be located in one position within the cell at any given time. Therefore, it is not necessary to send the requested system message on all SS / PBCH beams within the cell. Instead, it is only necessary to send the requested system message on a portion of the SS / PBCH beams. This reduces unnecessary broadcasting of the requested system message and reduces the time-frequency domain resources consumed by the requested system message.

[0043] like Figure 3 As shown, this disclosure provides a system message processing method, which is executed by a base station. The method includes:

[0044] S2101: Based on the direction of the terminal requesting the system message, transmit the system message requested by the terminal on a portion of the SS / PBCH beams.

[0045] There are several ways to determine the orientation of a terminal; for example, at least one of the following may be included:

[0046] The direction of the terminal is determined based on the uplink transmission using the final beam;

[0047] The direction of the terminal is determined based on the location information reported by the terminal.

[0048] Of course, the above is just an example of how a base station can determine the direction of a terminal.

[0049] In this embodiment of the disclosure, based on the direction of the terminal requesting the system message, one or more SS / PBCH beams whose transmission direction matches the direction of the terminal can be determined to transmit the system message requested by the terminal. In this way, on the one hand, the system message is sent to the terminal, and on the other hand, the number of SS / PBCH beams that send the system message requested by the terminal is reduced.

[0050] Figure 4 As shown, this disclosure provides a system message processing method, which is executed by a base station. The method includes:

[0051] S2201: Receive a request message sent by a terminal in the connected state on the first beam, the request message being used to request a system message.

[0052] Here, "connected state" is short for "RRC connected state." If the terminal is in connected state, an RRC connection is established between the terminal and the base station. At this time, the terminal can request system messages from the base station through this RRC connection. For example, the terminal can request system messages from the base station via RRC messages.

[0053] For example, the RRC message carries request information for a system message requested by the terminal and / or a message identifier for the requested system message. This message identifier can be used by the base station to determine the specific system message block currently being requested by the terminal. The system message requested by the terminal is a system message that the base station does not periodically broadcast.

[0054] In some embodiments, the system information is divided into minimum system information (minimum SI) and other system information (other SI), which includes all system information not broadcast in the minimum system information. This other system message can be broadcast to terminals in the RRC idle or inactive state, or unicast to terminals in the connected state via RRC signaling.

[0055] Figure 4 As shown, this disclosure provides a system message processing method, which is executed by a base station. The method includes:

[0056] S2201: Receive a request message sent by the terminal in the connected state on the first beam, the request message being used to request a system message.

[0057] S2202: Based on the direction of the first beam in which the terminal sends the request message, transmit the system message requested by the terminal on a portion of the SS / PBCH beams.

[0058] This request message is an uplink transmission from the terminal.

[0059] The first beam is the uplink beam for the terminal to transmit uplink data. When the base station receives a request from the terminal on the first beam, it can determine the terminal's direction relative to the base station based on the beam direction of the first beam. This allows it to further determine which SS / PBCH beams to send system messages on so that the terminal can successfully receive them.

[0060] For example, in some cases, the uplink and downlink beams satisfy beam consistency. In this case, a second beam that also satisfies beam consistency can be determined based on the first beam. The second beam used to transmit the SS / PBCH is then used to send the system message requested by the terminal.

[0061] For example, considering the mobility of the terminal, in order to maximize the probability of successful reception, in addition to sending the terminal request system message on the second beam for transmitting SS / PBCH, the terminal request system message is also sent on the third beam for transmitting SS / PBCH. The third beam is one or two beams whose beam direction is adjacent to that of the second beam.

[0062] In some possible implementations, S2001 transmits a system message requesting a terminal on a portion of the SS / PBCH beam, which may include:

[0063] The system message requested by the terminal is transmitted on the SS / PBCH beam, which has a predetermined type of quasi-co-located QCL relationship with the uplink reference signal beam corresponding to the Physical Uplink Shared Channel (PUSCH) through which the terminal transmitted the request message.

[0064] In some embodiments, the uplink reference signal beam is the beam that transmits the uplink reference signal. The uplink reference signal includes, but is not limited to, DMRS (demodulation reference signal) and SRS (sounding reference signal). Furthermore, the beam transmitting the PUSCH is the same as the uplink reference signal beam.

[0065] If the SRS beam of the base station has a predetermined type of QCL relationship with a certain SS / PBCH beam, it means that the large-scale parameters of the SRS beam and the SS / PBCH beam are consistent. The consistency of the large-scale parameters indicates that the channel conditions are roughly the same, so the system message requested by the terminal can be sent in the corresponding beam, and the terminal can successfully receive it.

[0066] In some embodiments, the large-scale parameter may include time delay spread, average time delay, Doppler spread, Doppler offset, average gain, and / or spatial reception parameters, etc.

[0067] Although the differences in spatial location or angle between stations are transparent to the terminal and the Coordinated Multiple Point Transmission (CoMP) operation itself, the impact of these spatial differences on large-scale channel parameters is an important factor that the terminal needs to consider when performing channel estimation and receiver detection.

[0068] In some possible implementations, step S2001, which involves transmitting a system message requesting a terminal on the partial synchronization signal / physical broadcast channel (SS / PBCH) beam, may include at least one of the following:

[0069] On the SS / PBCH beam that has a Quasi Co-Location (QCL) relationship with the Transmission Configured Indicate (TCI) of the Physical Downlink Control Channel (PDCCH) configured for the terminal, the system message requested by the terminal is transmitted.

[0070] On the SS / PBCH beam that has a predetermined type QCL relationship with the transmission configuration indication TCI of the PDCCH activated by the terminal, the system message requested by the terminal is transmitted.

[0071] On the SS / PBCH beam where the TCI of the PDSCH configured for the terminal has a predetermined type QCL relationship, the system message requested by the terminal is transmitted.

[0072] TCI is a type of information that indicates beam direction. When a base station configures the PDCCH for a terminal, if the base station and the terminal use beam communication, the corresponding TCI will be determined. The base station needs to refer to the terminal's location when configuring the PDCCH TCI. Therefore, the terminal can use the SS / PBCH beam with a predetermined type QCL relationship with the PDCCH TCI to send the system message requested by the terminal.

[0073] In some cases, the base station will configure multiple PDCCH TCIs for the terminal, but will only activate some or one of them. Ultimately, the beam corresponding to the activated TCI can be used for PDCCH transmission. Therefore, in this embodiment, the SS / PBCH beam for sending the system message requested by the terminal can also be determined based on the PDCCH TCI activated by the terminal.

[0074] PDSCH is a channel through which the base station transmits downlink data to the terminal. When configuring TCI on the PDSCH, it is also necessary to ensure that the terminal can receive it. The SS / PBCH beam with a predetermined type QCL relationship with the TCI configured on the PDSCH can be selected to transmit the system message requested by the terminal.

[0075] In some possible implementations, the predetermined type of QCL relationship includes: QCL relationship of type D.

[0076] If a QCL relationship of type D is present, it indicates that the spatial reception parameters are consistent, which can ensure that the two corresponding downlink beams point in the same direction, or that the corresponding uplink and downlink beams have beam consistency.

[0077] In some possible implementations, the active bandwidth (BWP) of the terminal is configured with a common search space for receiving other system messages.

[0078] The activated BWP of the terminal is the BWP configured by the base station for use by the terminal and which is activated.

[0079] For example, the activated BWP can be: a downlink BWP activated by the terminal.

[0080] If the active BWP of this terminal is configured with a public search space for other system messages, it means that the system message requested by the terminal may be sent within that public search space.

[0081] In this embodiment of the disclosure, after sending a request message for a system message, the system will wait in the public search space to receive the system message that requested it.

[0082] like Figure 5 As shown, this disclosure provides a system message processing method, which is executed by a terminal, and the method includes:

[0083] Step S5001: Receive the system message requested by the terminal on a portion of the SS / PBCH beams.

[0084] The SS / PBCH is a synchronization broadcast block used by the base station. The SS / PBCH may include: primary synchronization signal, secondary synchronization signal, and PBCH transmission.

[0085] In this embodiment of the disclosure, the SS / PBCH beam is a beam carrying the SS / PBCH. If the base station uses beams to communicate with the terminal, the base station will generally transmit the SS / PBCH on various beams within the cell, so that terminals located at different positions within the cell relative to the base station can establish synchronization with the base station based on the monitored SS / PBCH and access the base station.

[0086] Partial SS / PBCH beams are beams carrying SS / PBCH transmitted by the base station in a specific direction within the cell. This specific direction may include the direction in which the terminal is located.

[0087] For example, a base station may need M beams to transmit SS / PBCH within a cell using beam scanning, but it can transmit system messages requested by the terminal on N SS / PBCH beams, which is less than M.

[0088] A terminal requesting a system message will only be located in one position within the cell at any given time. Therefore, it is not necessary to send the requested system message on all SS / PBCH beams within the cell. Instead, it is only necessary to send the requested system message on a portion of the SS / PBCH beams. This reduces unnecessary broadcasting of the requested system message and reduces the time-frequency domain resources consumed by the requested system message.

[0089] In some possible implementations, receiving the system message requested by the terminal on a portion of the SS / PBCH beam may include:

[0090] Depending on the direction of the terminal, the system message requested by the terminal is received on a portion of the SS / PBCH beams.

[0091] There are several ways to determine the orientation of a terminal; for example, at least one of the following may be included:

[0092] The direction of the terminal is determined based on the uplink transmission using the final beam;

[0093] The direction of the terminal is determined based on the location information reported by the terminal.

[0094] Of course, the above is just an example of how a base station can determine the direction of a terminal.

[0095] In this embodiment of the disclosure, based on the direction of the terminal requesting the system message, one or more SS / PBCH beams whose transmission direction matches the direction of the terminal can be determined to transmit the system message requested by the terminal. In this way, on the one hand, the system message is sent to the terminal, and on the other hand, the number of SS / PBCH beams that send the system message requested by the terminal is reduced.

[0096] In some possible implementations, the method further includes:

[0097] The terminal in the connected state sends a request message on the first beam, the request message being used to request a system message.

[0098] If the terminal is in a connected state, an RRC connection is established between the terminal and the base station. The terminal can then request system messages from the base station through this RRC connection. For example, the terminal can request system messages from the base station via RRC messages.

[0099] For example, the RRC message carries request information for a system message requested by the terminal and / or a message identifier for the requested system message. This message identifier can be used by the base station to determine the specific system message block currently being requested by the terminal. The system message requested by the terminal is a system message that the base station does not periodically broadcast.

[0100] In some embodiments, additional system information includes all system information that is not broadcast in the minimum system information. This additional system message can be broadcast to terminals in the RRC idle or inactive state, or unicast to terminals in the connected state via RRC signaling.

[0101] In some possible implementations, the system message requested by the terminal on a portion of the SS / PBCH beam, as described in S5001, may include:

[0102] Based on the direction of the first beam from which the terminal sends the request message, the system message requested by the terminal is received on a portion of the SS / PBCH beams.

[0103] This request message is an uplink transmission from the terminal.

[0104] The first beam is the uplink beam for the terminal to transmit uplink data. When the base station receives a request from the terminal on the first beam, it can determine the terminal's direction relative to the base station based on the beam direction of the first beam. This allows it to further determine which SS / PBCH beams to send system messages on so that the terminal can successfully receive them.

[0105] For example, in some cases, the uplink and downlink beams satisfy beam consistency. In this case, a second beam that also satisfies beam consistency can be determined based on the first beam. The second beam used to transmit the SS / PBCH is then used to send the system message requested by the terminal.

[0106] For example, considering the mobility of the terminal, in order to maximize the probability of successful reception, in addition to sending the terminal request system message on the second beam for transmitting SS / PBCH, the terminal request system message is also sent on the third beam for transmitting SS / PBCH. The third beam is one or two beams whose beam direction is adjacent to that of the second beam.

[0107] In some possible implementations, S5001 receives the system message requested by the terminal on the SS / PBCH beam, including:

[0108] The system message requested by the terminal is received on the SS / PBCH beam where the uplink reference signal corresponding to the PUSCH that the terminal sends the request message has a predetermined type QCL relationship.

[0109] In some embodiments, the uplink reference signal beam is the beam that transmits the uplink reference signal. The uplink reference signal includes, but is not limited to, a probe reference signal. Furthermore, the beam transmitting the PUSCH is the same as the uplink reference signal beam.

[0110] If the SRS beam of the base station has a predetermined type of QCL relationship with a certain SS / PBCH beam, it means that the large-scale parameters of the SRS beam and the SS / PBCH beam are consistent. The consistency of the large-scale parameters indicates that the channel conditions are roughly the same, so the system message requested by the terminal can be sent in the corresponding beam, and the terminal can successfully receive it.

[0111] In some embodiments, the large-scale parameter may include time delay spread, average time delay, Doppler spread, Doppler offset, average gain, and / or spatial reception parameters, etc.

[0112] Although the differences in spatial location or angle between stations are transparent to the terminal and the multi-point cooperative transmission operation itself, the impact of these spatial differences on large-scale channel parameters is an important factor that the terminal needs to consider when performing channel estimation and reception detection.

[0113] In some possible implementations, the system message requested by the terminal is received on the partial synchronization signal / physical broadcast channel (SS / PBCH) beam, including at least one of the following:

[0114] On the SS / PBCH beam where the transmission configuration indication TCI of the PDCCH configured for the terminal has a predetermined type QCL relationship, the system message requested by the terminal is received;

[0115] On the SS / PBCH beam where the TCI of the PDCCH activated by the terminal has a predetermined type QCL relationship, the system message requested by the terminal is received;

[0116] On the SS / PBCH beam where the TCI of the PDSCH configured for the terminal has a predetermined type QCL relationship, a system message requested by the terminal is received.

[0117] TCI is a type of information that indicates beam direction. When a base station configures the PDCCH for a terminal, if the base station and the terminal use beam communication, the corresponding TCI will be determined. The base station needs to refer to the terminal's location when configuring the PDCCH TCI. Therefore, the terminal can use the SS / PBCH beam with a predetermined type QCL relationship with the PDCCH TCI to send the system message requested by the terminal.

[0118] In some cases, the base station will configure multiple PDCCH TCIs for the terminal, but will only activate some or one of them. Ultimately, the beam corresponding to the activated TCI can be used for PDCCH transmission. Therefore, in this embodiment, the SS / PBCH beam for sending the system message requested by the terminal can also be determined based on the PDCCH TCI activated by the terminal.

[0119] PDSCH is a channel through which the base station transmits downlink data to the terminal. When configuring TCI on the PDSCH, it is also necessary to ensure that the terminal can receive it. The SS / PBCH beam with a predetermined type QCL relationship with the TCI configured on the PDSCH can be selected to transmit the system message requested by the terminal.

[0120] In some possible implementations, the predetermined type of QCL relationship includes: QCL relationship of type D.

[0121] If a QCL relationship of type D is present, it indicates that the spatial reception parameters are consistent, which can ensure that the two corresponding downlink beams point in the same direction, or that the corresponding uplink and downlink beams have beam consistency.

[0122] In some possible implementations, the active portion bandwidth (BWP) of the terminal is configured with a common search space for receiving on-demand request system messages.

[0123] The activated BWP of the terminal is the BWP configured by the base station for use by the terminal and which is activated.

[0124] For example, the activated BWP can be: a downlink BWP activated by the terminal.

[0125] If the active BWP of this terminal is configured with a public search space for other system messages, it means that the system message requested by the terminal may be sent within that public search space.

[0126] In this embodiment of the disclosure, after sending a request message for a system message, the system will wait in the public search space to receive the system message that requested it.

[0127] The system message processing method provided in this disclosure allows the base station to broadcast the requested SI only on the SS / PBCH beam in the direction of the terminal, without having to broadcast the SI in all SS / PBCH beam directions. This reduces unnecessary broadcasting of requested system messages and reduces the time-frequency domain resources consumed by requested system messages.

[0128] In some possible implementations, when a connected terminal requests a System Information (SI), since the base station knows the beam direction in which the terminal is located, the base station only needs to broadcast the requested SI on the SS / PBCH beam in the direction in which the terminal is located, and does not need to broadcast the SI on all SS / PBCH beams.

[0129] For example, the base station transmits SI on a portion of the SS / PBCH beam.

[0130] For example, the SI is an SI requested and sent by the RRC connected state terminal.

[0131] For example, the SI is a non-broadcast SI.

[0132] For example, the active BWP of the connected terminal has a search space for receiving information from other systems.

[0133] For example, the base station may independently determine which portion of the SS / PBCH beams to select for transmitting SI. For instance, the base station may select a corresponding portion of the SS / PBCH beams based on the direction of the terminal.

[0134] For example, the portion of the SS / PBCH beams includes at least the SS / PBCH beams that have a type D QCL relationship with the TCI state of the configured PDCCH channel of the connected terminal.

[0135] For example, the portion of the SS / PBCH beams includes at least the SS / PBCH beams that have a type D QCL relationship with the TCI state of the currently active PDCCH channel of the connected terminal.

[0136] like Figure 6 As shown in the figure, this disclosure provides a system message processing apparatus, wherein the apparatus includes:

[0137] The first transmitting module 601 is configured to transmit a system message requesting a terminal on the partial synchronization signal / physical broadcast channel SS / PBCH beam.

[0138] In some possible implementations, when the first transmitting module 601 is configured to transmit a system message requesting a terminal on the partial synchronization signal / physical broadcast channel (SS / PBCH) beam, it transmits the system message requesting a terminal on the partial synchronization signal / physical broadcast channel (SS / PBCH) beam according to the direction in which the terminal is located.

[0139] In some possible implementations, the device further includes:
