The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part 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.

In Non-Terrestrial network (NTN) communication systems, such as 5G Terrestrial systems, the same beams are used for traffic and control. This approach is relatively simple to implement, but lacks flexibility. The implementation scheme of beam separation of control and service can make full use of power resource of satellite load, reduce occupation of signaling, and make beam to user be distributed according to requirement. The control beam is mainly used for the communication processes of uplink and downlink synchronization, access and the like, and the service beam is mainly used for data transmission.

Taking the coverage of a single satellite as an example, the coverage of the satellite is divided into 36 wave bits, and only 8 beams are supported in total according to the power capability of the satellite. As shown in fig. 1, a control and traffic integrated beam configuration is shown, where each of the 8 beams supports control and traffic, resulting in service to only users within the coverage of the control beam. As shown in fig. 2, a beam configuration with separate control and service is provided, in which 1 beam is dedicated to control, and another 7 beams are used for service, and a user obtains basic information required for access from the control beam and then performs data transmission on the service beam.

The embodiment of the invention provides a beam indicating method, a beam determining device, network equipment and a terminal, which are used for solving the problem that errors can occur in an access process because no technical means is provided for distinguishing beam types and corresponding access flow differences in the prior art.

The method and the apparatus (and the corresponding network device or terminal) are based on the same application concept, and because the principles of solving the problems of the method and the apparatus (and the corresponding network device or terminal) are similar, the implementation of the apparatus (and the corresponding network device or terminal) and the method can be mutually referred, and repeated parts are not repeated.

As shown in fig. 3, an embodiment of the present invention provides a beam indication method, including:

step 31: and the network equipment sends downlink signals to the terminal through the downlink wave beams.

Optionally, the beam type includes: a first beam type and/or a second beam type; wherein the first beam type is used for initial access and broadcast message transmission; the second beam type is used for data transmission, or the second beam type is used for data transmission and initial access.

The first beam type may also be referred to as a control beam, that is, the control beam is mainly used for transmission of initial access and broadcast messages, such as supporting transmission/reception of broadcast signaling and synchronous access signals; the second beam type may also be referred to as a service beam, that is, the service beam is mainly used for supporting data transmission of a user and may also support access and data transmission of the user.

As an implementation manner, the network device may pre-configure different beam types corresponding to different frequency point information, so that the terminal may distinguish the beam types based on the frequency point information corresponding to the received downlink signal, for example, distinguish a first beam type (or referred to as a control beam) from a second beam type (or referred to as a service beam).

As another implementation manner, the network device may indicate the corresponding beam type through indication information carried in the downlink signal, so that the terminal may distinguish the beam types based on the indication information, for example, distinguish a first beam type (or referred to as a control beam) from a second beam type (or referred to as a service beam).

In the above scheme, different beam types are preconfigured by the network device to correspond to different frequency point information, so that when a downlink signal is sent to the terminal through the downlink beam, the terminal can determine the beam type of the downlink beam according to the frequency point information for receiving the downlink signal, and/or the downlink signal sent to the terminal by the network device through the downlink beam carries indication information for indicating the beam type corresponding to the downlink signal, so that the terminal can determine the beam type corresponding to the downlink signal according to the indication information. The scheme can facilitate the terminal to accurately identify the beam type of the received beam, so as to quickly establish communication with the network in the corresponding beam and avoid the problem that the terminal possibly causes errors in the access process due to the fact that the beam type and the corresponding access flow difference cannot be distinguished.

Specifically, in the scheme, the network device provides the terminal with a pre-configuration or signaling notification mode to distinguish different beam types, so that the terminal can select a proper bandwidth resource and a proper signal format during initial access, a broadcast message is read and an uplink access signal is sent, a subsequent access process is completed, and errors of the terminal in the access process are avoided.

For example: under the condition that the beam types comprise a first beam type and a second beam type, the network equipment can pre-configure first frequency point information corresponding to the first beam type and second frequency point information corresponding to the second beam type; the configuration information for indicating the mapping relationship between the beam type and the frequency point information may be notified to the terminal in advance by the network device side as an agreed information.

In this way, the network device can send downlink signals corresponding to the frequency point information to the terminal according to the frequency point information corresponding to the different preconfigured beam types, so that the terminal side can perform cell search based on the frequency point information corresponding to the different preconfigured beam types, and when receiving the downlink signals, can determine the beam type corresponding to the downlink signals based on the frequency point information corresponding to the downlink signals when receiving the downlink signals, and further establish information interaction with the network based on the corresponding beam type, and if the current beam is the first beam type (i.e., control beam), the terminal can perform control processes such as initial access, switching and the like; when the current beam is the second beam type (i.e., the service beam), the terminal may perform data transmission or may also perform initial access.

the network equipment sends a broadcast message and/or a system message to the terminal through a downlink wave beam;

For example: the network device may carry, through the MIB, indication information for indicating a beam type corresponding to the downlink signal, and/or carry, through the SIB, indication information for indicating a beam type corresponding to the downlink signal; that is, the embodiment of the present invention may distinguish the first beam type and the second beam type (i.e., distinguish the control beam from the service beam) through the MIB information, and/or distinguish the first beam type and the second beam type (i.e., distinguish the control beam from the service beam) through the SIB.

a first bit in the MIB;

a first field in the MIB.

Wherein, the first bit in the MIB is used to indicate the beam type corresponding to the downlink signal, for example, the network device adds a bit in the MIB information to explicitly indicate the beam type, that is, the MIB is used to indicate the beam type corresponding to the downlink signal in an explicit manner, and specifically, 1bit may be used to indicate, for example, 1 is a control beam and 0 is a service beam; or 0 is a control beam, 1 is a traffic beam, etc. It should be noted that the first bit in the embodiment of the present invention is not limited to be specifically which bit in the MIB, and it may be understood that a certain bit in the MIB can be used to explicitly indicate the beam type.

The existing fields may specifically be at least one of a field for indicating a BWP index, a field for indicating a BWP type, a field for indicating a control channel index, and a field for indicating a control channel parameter, so as to implicitly indicate the beam type corresponding to the first beam.

Specifically, when the first field in the MIB indicates the beam type corresponding to the downlink signal, the first field may include at least one of the following:

a first field for indicating a BWP index; wherein the BWP index is associated with a BWP type, and the different beam types correspond to different BWP types. For example: the BWP index and the BWP type have a mapping relation, and the terminal can determine the corresponding BWP type based on the BWP index by indicating the BWP index; the BWP type corresponding to the first beam type (i.e., the control beam) may be an initial access BWP (initial access BWP) and/or a specific (or pre-configured) BWP type that is different from the BWP type corresponding to the second beam type (i.e., the traffic beam).

A first field indicating a BWP type; wherein different beam types correspond to different BWP types. For example: the BWP type corresponding to the first beam type (i.e., the control beam) may be an initial access BWP and/or a specific (or pre-configured) BWP type that is different from the BWP type corresponding to the second beam type (i.e., the service beam).

A first field for indicating a control channel index; the control channel index is associated with the control channel parameter, and different beam types correspond to different control channel parameters. For example: the control channel index and the control channel parameter have a mapping relation, and the terminal can determine the corresponding control channel parameter based on the control channel index by indicating the control channel index; for example, the control channel parameters of the first beam type (i.e., the control beam) include that the number of Physical Resource Blocks (PRBs) is 20, the number of symbols is 3 or 6, and the control channel parameters of the second beam type (i.e., the traffic beam) include that the number of PRBs is not 20, and/or the number of symbols is not 3 or 6, etc., which is not limited in the embodiments of the present invention.

A first field for indicating control channel parameters; wherein different beam types correspond to different control channel parameters. For example: the control channel parameters corresponding to the first beams of different beam types may be different, where the control channel parameters of the first beam type (i.e., the control beam) include 20 PRBs and 3 or 6 symbols, and the control channel parameters of the second beam type (i.e., the service beam) include 20 PRBs and/or 3 or 6 symbols, which is not limited in the embodiments of the present invention.

a second bit in the first SIB;

a second field in a second SIB.

The first SIB and the second SIB may be the same or different, for example, the first SIB may be SIB1, the second SIB may be SIBx (e.g., other SIBs except SIB1, or a newly added SIB), and the like, which is not limited in this embodiment of the application.

Wherein, the beam type corresponding to the downlink signal is indicated by the second bit in the first SIB, for example, the network device explicitly indicates the beam type by adding a bit in the first SIB information, that is, the beam type corresponding to the downlink signal is indicated in an explicit manner by the first SIB, and specifically, the indication may be 1-bit indication, for example, 1 is a control beam and 0 is a service beam; or 0 for control beam, 1 for traffic beam, etc. It should be noted that the second bit in the embodiment of the present invention is not limited to be specifically the bit in the first SIB, and it is understood that any bit in the first SIB may be adopted, and the beam type may be explicitly indicated.

The beam type corresponding to the downlink signal is indicated by a second field in the second SIB, for example, the network device marks the beam type by using different values of existing fields in the second SIB information, that is, the beam type corresponding to the downlink signal is indicated in an implicit manner by the second SIB, where the existing fields may specifically be at least one of a field for indicating a beam width, a field for indicating a serving cell number, a field for indicating a bandwidth range, a field for indicating a cell identifier, a second field for indicating a BWP index, and a field for indicating a BWP type, so as to implicitly indicate the beam type corresponding to the downlink signal.

Specifically, when a second field in the second SIB indicates a beam type corresponding to the downlink signal, the second field includes at least one of the following:

a second field for indicating a beam width; wherein different beam types correspond to different beam widths. For example: the first beam type (i.e., control beam) is a wide beam and the second beam type (i.e., traffic beam) is a narrow beam.

A second field for indicating a number of service wave bits; wherein, different beam types correspond to different service wave bit numbers. For example: the number of service beams is less for the first beam type (i.e., control beam) and more for the second beam type (i.e., traffic beam).

A second field for indicating a bandwidth range; wherein different beam types correspond to different bandwidth ranges. For example: the first beam type (i.e., the control beam) is narrower in bandwidth (i.e., small in bandwidth range) and the second beam type (i.e., the traffic beam) is larger in bandwidth (i.e., large in bandwidth range).

A second field for indicating a cell identity; wherein, different beam types correspond to different cell identifications. For example: the first beam type and the second beam type (i.e., the control beam and the service beam) are preconfigured to correspond to different cell ID numbers.

A second field for indicating a BWP index; wherein the BWP index is associated with a BWP type, and different beam types correspond to different BWP types; for example: the BWP index and the BWP type have a mapping relation, and the terminal can determine the corresponding BWP type based on the BWP index by indicating the BWP index; the BWP type corresponding to the first beam type (i.e., the control beam) may be an initial access BWP and/or a specific (or pre-configured) BWP type that is different from the BWP type corresponding to the second beam type (i.e., the service beam).

A second field for indicating a BWP type; wherein different beam types correspond to different BWP types. For example: the BWP type corresponding to the first beam type (i.e., the control beam) may be an initial access BWP and/or a specific (or pre-configured) BWP type that is different from the BWP type corresponding to the second beam type (i.e., the service beam).

The processor-readable storage medium can be any available medium or data storage device that can be accessed by a processor, including, but not limited to, magnetic memory (e.g., floppy disks, hard disks, magnetic tape, magneto-optical disks (MOs), etc.), optical memory (e.g., CDs, DVDs, BDs, HVDs, etc.), and semiconductor memory (e.g., ROMs, EPROMs, EEPROMs, non-volatile memories (NAND FLASH), solid State Disks (SSDs)), etc.

The beam indicating method according to the embodiment of the present invention is introduced from the network device side, and the beam determining method at the terminal side will be further described with reference to the drawings.

As shown in fig. 6, an embodiment of the present invention provides a beam determination method, including:

step 61: and the terminal receives a downlink signal sent by the network equipment through the downlink wave beam.

Step 62: and the terminal determines the beam type of the downlink beam according to the downlink signal.

In the above scheme, the network device pre-configures different beam types to correspond to different frequency point information, so that when sending a downlink signal to the terminal through the downlink beam, the terminal can determine the beam type of the downlink beam according to the frequency point information for receiving the downlink signal, and/or the network device carries indication information for indicating the beam type corresponding to the downlink signal in the downlink signal sent to the terminal through the downlink beam, so that the terminal can determine the beam type corresponding to the downlink signal according to the indication information. The scheme can facilitate the terminal to accurately identify the beam type of the received beam, so as to quickly establish communication with the network in the corresponding beam and avoid the problem that the terminal possibly causes errors in the access process due to the fact that the beam type and the corresponding access flow difference cannot be distinguished.

Optionally, after the terminal determines the beam type of the downlink beam according to the downlink signal, the method may further include:

Optionally, when the beam type is the first beam type (i.e., control beam), the access mode may be that the terminal first sends a random access signal, then receives the random access signal, and the terminal performs a subsequent random access operation according to the indication information of the random access signal. For example: if the terminal determines that the current beam is the control beam according to the downlink signal, the terminal may perform related processing of the control beam, for example, the terminal may perform control processes such as initial access and handover.

When the beam type is a second beam type (i.e., a service beam), the access mode may be that the terminal first sends a random access preamble (preamble) signal to the network; then, a Random Access Response (RAR) signal is received, a Physical Uplink Shared Channel (PUSCH) signal is sent based on the RAR signal, uplink Radio Resource Control (RRC) connection request information is carried, and the terminal receives a network contention resolution signal. For example: if the terminal determines that the current beam is a service beam according to the downlink signal, the terminal may perform relevant processing of the service beam, for example, the terminal may perform data transmission or may perform initial access.

For example: under the condition that the beam types comprise a first beam type and a second beam type, the network equipment can pre-configure first frequency point information corresponding to the first beam type and second frequency point information corresponding to the second beam type; the configuration information for indicating the mapping relationship between the beam type and the frequency point information may be notified to the terminal in advance by the network device side as a kind of appointment information, and then the terminal side may store the correspondence between the frequency point information and the beam type preconfigured by the network device in advance as a kind of appointment information.

In this way, the network device can send downlink signals corresponding to the frequency point information to the terminal according to the preconfigured frequency point information corresponding to different beam types, so that the terminal side can perform cell search based on the preconfigured frequency point information corresponding to different beam types, and when receiving the downlink signals, can determine the beam type corresponding to the downlink signals based on the frequency point information for receiving the downlink signals, and further establish information interaction with the network based on the corresponding beam type, and if the current beam is the first beam type (i.e., control beam), the terminal can perform control processes such as access, switching and the like; when the current beam is the second beam type (i.e., the service beam), the terminal may perform data transmission or may also perform initial access.

wherein the broadcast message and/or the system message carry indication information for indicating a beam type corresponding to the downlink signal.

For example: the network device may carry, through the MIB, indication information used to indicate a beam type corresponding to the downlink signal, and/or carry, through an SIB, indication information used to indicate a beam type corresponding to the downlink signal; that is, the embodiment of the present invention may distinguish the first beam type and the second beam type (i.e., distinguish the control beam from the service beam) through the MIB information, and/or distinguish the first beam type and the second beam type (i.e., distinguish the control beam from the service beam) through the SIB.

Specifically, under the condition that the network device does not pre-configure different frequency point information corresponding to different beam types, that is, the terminal does not know the frequency point information of the first beam type and the second beam type (that is, the control beam and the service beam), the terminal may perform blind search to the satellite, may obtain MIB information after the satellite search is successful, and under the condition that the network device carries indication information for indicating the beam type corresponding to the downlink signal through the MIB, the terminal may determine from the MIB information whether the current beam is the first beam type or the second beam type (that is, determine whether the current beam is the control beam or the service beam);

and/or, in a case that downlink signals of different beam types, which are not preconfigured by the network device, correspond to different frequency point information, that is, the terminal does not know frequency point information of the first beam type and the second beam type (that is, a control beam and a service beam), the terminal may perform blind search to the satellite, may acquire information such as MIB and SIB after the satellite search is successful, and in a case that the network device carries indication information for indicating the beam type corresponding to the downlink signal through the SIB, the terminal may determine, from the SIB information, whether the current beam is the first beam type or the second beam type (that is, determine whether the current beam is the control beam or the service beam).

a first bit in the MIB;

a first field in the MIB.

Wherein, the first bit in the MIB is used to indicate the beam type corresponding to the downlink signal, for example, the network device adds a bit in the MIB information to explicitly indicate the beam type, that is, the MIB is used to indicate the beam type corresponding to the downlink signal in an explicit manner, and specifically, 1bit may be used to indicate, for example, 1 is a control beam and 0 is a service beam; or 0 is a control beam, 1 is a traffic beam, etc. It should be noted that the first bit in the embodiment of the present invention is not limited to which bit in the MIB is specific, and it may be understood that a certain bit in the MIB may be used to explicitly indicate a beam type.

The first field in the MIB is used to indicate the beam type corresponding to the downlink signal, for example, the network device marks the beam type by using different values of existing fields in MIB information, that is, the MIB implicitly indicates the beam type corresponding to the downlink signal, where the existing fields may specifically be at least one of a field for indicating a BWP index, a field for indicating a BWP type, a field for indicating a control channel index, and a field for indicating a control channel parameter, so as to implicitly indicate the beam type corresponding to the first beam.

Optionally, when a first field in the MIB indicates a beam type corresponding to the downlink signal, the first field may include at least one of:

a first field to indicate a BWP index; wherein the BWP index is associated with a BWP type, and the different beam types correspond to different BWP types. For example: the BWP index and the BWP type have a mapping relation, and the terminal can determine the corresponding BWP type based on the BWP index by indicating the BWP index; the BWP type corresponding to the first beam type (i.e., the control beam) may be an initial access BWP and/or a specific (or pre-configured) BWP type that is different from the BWP type corresponding to the second beam type (i.e., the service beam).

A first field indicating a BWP type; wherein different beam types correspond to different BWP types. For example: the BWP type corresponding to the first beam type (i.e., the control beam) may be an initial access BWP and/or a specific (or pre-configured) BWP type that is different from the BWP type corresponding to the second beam type (i.e., the traffic beam).

A first field for indicating a control channel index; wherein the control channel index is associated with a control channel parameter, and different beam types correspond to different control channel parameters. For example: the control channel index and the control channel parameter have a mapping relation, and the terminal can determine the corresponding control channel parameter based on the control channel index by indicating the control channel index; for example, the control channel parameters of the first beam type (i.e., control beam) include 20 PRBs and 3 or 6 symbols, and the control channel parameters of the second beam type (i.e., service beam) include that the number of PRBs is not 20 and/or the number of symbols is not 3 or 6, etc., which is not limited in the embodiments of the present invention.

A first field for indicating control channel parameters; wherein different beam types correspond to different control channel parameters. For example: the control channel parameters corresponding to the first beam of different beam types may be different, where the control channel parameters of the first beam type (i.e., the control beam) include 20 PRBs, and the number of symbols is 3 or 6, and the control channel parameters of the second beam type (i.e., the service beam) include the number of PRBs is not 20, and/or the number of symbols is not 3 or 6, and the like, and the embodiments of the present invention are not limited thereto.

a second bit in the first SIB;

a second field in a second SIB.

The first SIB may be the same as or different from the second SIB, for example, the first SIB may be SIB1, the second SIB may be SIBx (e.g., another SIB other than SIB1, or a newly added SIB), and the like.

Wherein, the beam type corresponding to the downlink signal is indicated by the second bit in the first SIB, for example, the network device explicitly indicates the beam type by adding a bit in the first SIB information, that is, the beam type corresponding to the downlink signal is indicated in an explicit manner by the first SIB, and specifically, the indication may be 1-bit indication, for example, 1 is a control beam and 0 is a service beam; or 0 is a control beam, 1 is a traffic beam, etc. It should be noted that the second bit in the embodiment of the present invention is not limited to be specifically the bit in the first SIB, and it is understood that any bit in the first SIB may be adopted, and the beam type may be explicitly indicated.

A second field for indicating a bandwidth range; wherein different beam types correspond to different bandwidth ranges. For example: the first beam type (i.e., the control beam) has a narrower bandwidth (i.e., a small bandwidth range) and the second beam type (i.e., the traffic beam) has a larger bandwidth (i.e., a large bandwidth range).

A second field indicating a BWP type; wherein different beam types correspond to different BWP types. For example: the BWP type corresponding to the first beam type (i.e., the control beam) may be an initial access BWP and/or a specific (or pre-configured) BWP type that is different from the BWP type corresponding to the second beam type (i.e., the service beam).

In the following, a beam indicating method according to the present invention is described with reference to a specific embodiment, where a control beam may refer to the first beam type, and a service beam may refer to the second beam type.

The first embodiment is as follows: an independent working frequency band distinguishing method, namely different wave beam types correspond to different frequency point information;

specifically, the network device divides independent working frequency bands for the control beam and the service beam, and the frequency band F1 of the control beam and the frequency band F2 of the service beam are predetermined in advance and stored at the terminal (UE) side and the network side. And when the UE is accessed to the network, judging whether the control beam or the service beam is the control beam or the service beam according to the frequency of the downlink signal.

For example: controlling the wave beam to work at 19GHz-19.02GHz in a total of 20MHz; the service beam downlink works at 19.02GHz-20.02GHz, and the total frequency is 1GHz. The control beam and the service beam are independent and non-overlapping in frequency band, and are easy to distinguish by the UE. The UE may identify the control beam or the service beam through the operating frequency band.

Example two: indicating the beam type by using a broadcast message MIB;

specifically, the beam type is indicated by using the identifier bit of the MIB information in the broadcast message, and the current beam is distinguished as belonging to a control beam or a service beam.

Mode (1): adding 1bit beam identifier in the MIB to indicate the beam type, specifically adding 1bit in the MIB information to indicate the beam type: "0" indicates a control beam and "1" indicates a traffic beam.

Mode (2): based on the parameter indication of the control channel, the PRBs of the control channel (e.g., PDCCH) of a specific control beam are fixed to 20, and the number of symbols is 3 or 6. The number of PRBs and the number of symbols of the control channel (PDCCH) of the traffic beam are not fixed and variable. For example: if the PDCCH has PRB =20 and symbol =3 or 6, this indicates that the beam is a control beam. If the PDCCH has PRB =20, symbol number ≠ 3, PRB ≠ 20, symbol number =3, PRB ≠ 20, and symbol number ≠ 3, it indicates that the beam is a traffic beam.

Mode (3): the beam type is indicated based on the high 4 bits of the pdcch-ConfigSIB1 in the MIB, i.e. by the control channel index. For example: the high four-digit values of Pdcch-ConfigSIB1 are: "0000" - "1001", which represents a service beam; the high four-digit values of Pdcch-ConfigSIB1 are: and 1100 to 1111, a control beam is indicated.

As table 1 shows embodiments of the mode (2) and the mode (3), the first column is an index (index) indicated by Pdcch-ConfigSIB1, and the second column indicate the Pdcch symbol number and RB number.

TABLE 1

Example three: indicating the beam type by using a system message SIB 1;

for example: adding 1bit in SIB1 for indicating beam type: "0" indicates a control beam and "1" indicates a traffic beam.

Example four: implicitly indicating the beam type with other system messages SIBx;

mode (1): the beam type is indicated based on different beam widths (patterns), which for a particular beam represent the order in which the beam accesses different wave bits, indicated in the SIB. The control beam adopts a polling mode, and the pattern of the control beam access is fixed; the pattern of the service beam is variable in relation to the scheduling state of the current network. For example: if the beam pattern indicated by the current SIB is fixed and unchanged, the control beam is represented; if the beam pattern indicated by the current SIB is variable and aperiodic, it represents a service beam.

Mode (2): and indicating the beam type based on different service beam bit numbers, and particularly distinguishing a control beam from a service beam through the service beam number indicated by the SIB. For example: the number of service wave bits of the control wave beam is different from the number of service wave bits of the service wave beam, the number of service wave bits of the control wave beam is small, the number of service wave bits of the service wave beam is large, the service wave bit number is small to represent the control wave beam, and the service wave bit number is large to represent the service wave beam.

Mode (3): the beam type is indicated based on different beam bandwidths, and the control beam or the service beam is distinguished by specifically utilizing the bandwidth of the current beam. For example: the bandwidth of the control beam is fixed and unchanged, and the bandwidth of the service beam is larger than that of the control beam. If the beam bandwidth is small, the control beam is represented, and the beam bandwidth is large, the service beam is represented.

Mode (4): and indicating the beam type based on different cell IDs, and particularly distinguishing a control beam or a service beam by using the cell IDs. For example: a fixed cell ID is assigned to the control beam, such as "0" for the control beam cell and "others" for the traffic beam cell.

Mode (5): a special type of BWP may be specifically defined based on the different BWP types indicated beam types, which are distinguished from the existing initial BWP and the dedicated BWP. A special type of BWP is indicated in SIB1, indicating a control beam, such as defined as an initial access BWP, so that it is possible to distinguish between a control beam or a traffic beam using a BWP type indication.
