Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
In making the description of the embodiments of the present invention, some concepts used in the following description will first be explained.
Industrial Internet of things (IIOT) project background
RAN #80 conference agreed to IIOT standing. In an industrial environment, many applications (e.g., manufacturing, machine control, etc.) have high performance requirements, such as low latency, high reliability, and directional information transfer. The IIOT project is intended to provide a LAN type communication service for such vertical industries through a 5G communication network, meeting the communication demands of the vertical industries.
In an industrial environment, most applications require high precision time synchronization (e.g., 1 microsecond) between nodes. The IIOT monograph indicates that it is desirable to study how the network side provides the reference time to the terminal by broadcasting or unicasting to achieve synchronization.
The R15LTE supports the broadcast and unicast modes to provide reference time for the terminal, but in order to ensure that the actual reference time positions of the reference time provided by the network side and the terminal for the unicast mode are understood together, the network side needs to additionally carry a reference SFN (system frame number, which is a reference SFN for generating the reference time by the network side, and the reference time position corresponding to the reference time is set as an ending boundary of the reference SFN) while providing the reference time. But the reference SFN carried in addition takes 10 bits, and the overhead is relatively large.
The invention provides a reference time position determining method, a transmission method, a terminal and network equipment aiming at the problems.
As shown in fig. 1, an embodiment of the present invention provides a method for determining a reference time position, which is applied to a terminal and includes:
step 101, receiving a reference time message sent by a network device;
wherein the reference time message includes: a reference time (time reference) and indication information of a transmission position of the reference time message;
it should be noted that the reference time includes at least one of the following information: universal Coordinated Time (UTC), sunlight Saving Time (DST), Global Positioning System (GPS) Time, and local Time.
The indication information is used for indicating the position of the initial sending position of the reference time message in a first configuration; in particular, the first configuration comprises one of the following information: system message change period, system message sending window, paging period and the range of the system frame number.
The indication information may be indicated by 1 bit, or may be indicated by a plurality of bits; preferably, the indication information is indicated by 1 bit.
Preferably, the indication information is used to indicate that the initial transmission position of the reference time message is in the first half period or the second half period of the system change period, for example, when 1 bit is used for indication, the value of the indication information is "0", which indicates that the indication information is in the first half period, and the value of the indication information is "1", which indicates that the indication information is in the second half period; alternatively, the first and second electrodes may be,
the indication information is used for indicating whether the initial sending position of the reference time message is in the first half window or the second half window of the system message sending window; alternatively, the first and second electrodes may be,
the indication information is used for indicating whether the initial sending position of the reference time message is in the first half period or the second half period of the paging cycle; alternatively, the first and second electrodes may be,
the indication information is used for indicating whether the system frame number corresponding to the initial sending position of the reference time message is in a first range or a second range; preferably, the first range refers to a system frame number range between 0 and 511 and the second range refers to a system frame number range between 512 and 1023. It should be noted that, in this embodiment, the system frame number range indicated by the first range is not specifically limited, and the system frame number range indicated by the second range is also not specifically limited.
102, determining an actual reference time position corresponding to the reference time according to the indication information, a preset reference time position and a receiving position of the reference time message;
it should be noted that the preset reference time position may be configured by a protocol convention or a network device, and includes one of the following information:
a11, a first boundary of a system message change period;
it should be noted that the first boundary is a start boundary or an end boundary; i.e. the beginning boundary of the system message change period or the ending boundary of the system message change period.
A12, a first boundary of a system messaging window;
i.e., the beginning boundary of the system messaging window, or the ending boundary of the system messaging window.
A13, first boundary of paging cycle;
i.e., the starting boundary of the paging cycle, or the ending boundary of the paging cycle.
A14, presetting a first boundary of a system frame corresponding to a system frame number;
it should be noted that the preset system frame number is an assigned system frame number; the method specifically comprises the following steps: the starting boundary of the system frame corresponding to the specified system frame number, or the ending boundary of the system frame corresponding to the specified system frame number.
The preset reference time position is a basis for generating reference time by the network equipment appointed by a protocol or configured by the network equipment, namely the preset reference time position is a macroscopic concept, and the actual reference time position refers to an actual position of the reference time generated by the network equipment; for example, the protocol stipulates that the preset reference time position is the ending boundary of the system message change period, and the actual reference time position is specifically which ending boundary of the system message change period.
It should be noted that the positions in the embodiments of the present invention are all referred to as time domain positions.
Specifically, the specific implementation manner of step 102 is as follows:
and determining an actual reference time position corresponding to the reference time according to a first preset rule.
In addition, when the information included in the first configuration is different, the specific implementation of the first preset rule is also different, and the following description is provided below.
The first configuration comprises: system message change cycle, system message sending window or paging cycle
In this way, the first preset rule is implemented by one of the following ways:
b11, if the initial sending position of the reference time message is at the first position in the first configuration, determining the first boundary of the first configuration where the receiving position is located as the actual reference time position;
it should be noted that the first boundary is a start boundary or an end boundary, and further, the first boundary is the same as a boundary specified in the preset reference time position, that is, the network device and the terminal side understand the first boundary identically.
For example, when the preset reference time position is a first boundary of a system message change cycle, and the indication information indicates that the initial sending position of the reference time message is in the first half cycle of the system message change cycle, determining that the first boundary of the system message change cycle where the receiving position is located is the actual reference time position; specifically, when the first boundary is an end boundary, and when the indication information indicates that the initial transmission position of the reference time message is in the first half period of the system message change cycle, the end boundary of the system message change cycle in which the receiving position is located is determined to be the actual reference time position.
For example, when the preset reference time position is a first boundary of a system message sending window, and the indication information indicates that the initial sending position of the reference time message is in the first half period of the system message sending window, determining that the first boundary of the system message sending window where the receiving position is located is an actual reference time position corresponding to the reference time; specifically, when the first boundary is an end boundary, and when the indication information indicates that the initial transmission position of the reference time message is in the first half period of a system message transmission window, it is determined that the end boundary of the system message transmission window where the receiving position is located is an actual reference time position corresponding to the reference time.
For example, when the preset reference time position is the first boundary of the paging cycle, and the indication information indicates that the initial sending position of the reference time message is in the first half period of the paging cycle, determining that the first boundary of the paging cycle where the receiving position is located is the actual reference time position corresponding to the reference time; specifically, when the first boundary is an end boundary, and the indication information indicates that the initial transmission position of the reference time message is in the first half period of the paging cycle, it is determined that the end boundary of the paging cycle where the receiving position is located is an actual reference time position corresponding to the reference time.
B12, if the initial sending position of the reference time message is at the second position in the first configuration and the receiving position is at the first position in the first configuration, determining the first boundary of the previous first configuration of the first configuration where the receiving position is located as the actual reference time position corresponding to the reference time;
it should be noted that the first position belongs to a first part in the first configuration, and the second position belongs to a second part in the first configuration; and the position of the first portion is before the position of the second portion; for example, the first position is located in the first half period of the system message change period, and the second position is located in the second half period of the system message change period; or the first position is positioned in the first half period of the system message sending window, and the second position is positioned in the second half period of the system message sending window; or the first position is located in the first half period of the paging cycle and the second position is located in the second half period of the paging cycle.
For example, when the preset reference time position is a first boundary of the system message change period, when the network device indicates that the initial sending position of the reference time message is in the latter half period of the system message change period and the receiving position is in the former half period of the system message change period, the terminal determines that the first boundary of the system message change period before the system message change period where the receiving position is located is an actual reference time position corresponding to the reference time; specifically, when the first boundary is an end boundary, when the network device indicates that the initial sending position of the reference time message is in the second half period of the system message change period and the receiving position is in the first half period of the system message change period, the terminal determines that the end boundary of the system message change period before the system message change period where the receiving position is located is the actual reference time position corresponding to the reference time. For example, as shown in fig. 2, the network device side generates a reference time based on the ending boundary of the system message change period N, and the initial sending position of the reference time message is in the second half period of the system message change period N, and if the terminal receives the reference time message in the first half period of the system message change period N +1, the terminal determines the actual reference time position corresponding to the reference time as the ending boundary of the system message change period N.
It should be noted that, in the case of the system message sending window or the paging cycle, the determination method of the actual reference time position is the same as the determination method in the system message change cycle, and is not described herein again.
B13, if the initial sending position of the reference time message is at the second position in the first configuration and the receiving position is at the second position in the first configuration, determining the first boundary of the first configuration where the receiving position is located as the actual reference time position corresponding to the reference time;
for example, when the preset reference time position is a first boundary of the system message change period, when the network device indicates that the initial sending position of the reference time message is in the latter half of the system message change period and the receiving position is in the latter half of the system message change period, the terminal determines that the first boundary of the system message change period where the receiving position is located is an actual reference time position corresponding to the reference time; specifically, when the first boundary is an end boundary, when the network device indicates that the initial transmission position of the reference time message is in the second half of the system message change period and the receiving position is in the second half of the system message change period, the terminal determines that the end boundary of the system message change period where the receiving position is received is the actual reference time position corresponding to the reference time.
It should be noted that, in this manner, in the case of the system message transmission window or the paging cycle, the determination manner of the actual reference time position is the same as the determination manner in the system message change cycle, and is not described herein again.
The second configuration comprises: range of system frame number
In this way, the preset reference time position is a first boundary of a system frame corresponding to a preset system frame number, and specifically, the first preset rule is implemented by one of the following manners:
b21, if the initial sending position of the reference time message is at the first position in the system frame number range, obtaining the first system frame corresponding to the system frame number range where the receiving position is located, and determining the first boundary of the first system frame as the actual reference time position corresponding to the reference time;
it should be noted that the frame number of the first system frame is the same as the preset system frame number, that is, the frame number of the first system frame is the specified system frame number; the first boundary is a start boundary or an end boundary.
For example, when the first boundary is an end boundary, at a first position in a system frame number range where the initial transmission position of the reference time message is located, acquiring a first system frame corresponding to the system frame number range where the reception position is located, and determining the end boundary of the first system frame as an actual reference time position corresponding to the reference time.
B22, if the initial sending position of the reference time message is at the second position in the range of the system frame number where the reference time message is located, and the receiving position is at the first position in the range of the system frame number where the reference time message is located, acquiring a second system frame corresponding to the range of the system frame number in the previous round in the range of the system frame number where the receiving position is located, and determining the first boundary of the second system frame as the actual reference time position corresponding to the reference time;
it should be noted that the system frame number is cyclically valued according to 0 to 1023, and each cycle is called a round. The first position is located in a first part of the range of the system frame number, and the second position is located in a second part of the range of the system frame number; and the position of the first part is before the position of the second part, for example, the first position is a system frame corresponding to a certain system frame number within the range of system frame numbers 0-511, and the second position is a system frame corresponding to a certain system frame number within the range of system frame numbers 512-1023.
It should be noted that the frame number of the second system frame is the same as the preset system frame number, that is, the frame number of the second system frame is the specified system frame number; the first boundary is a start boundary or an end boundary.
For example, when the first boundary is an end boundary, at a second position in the system frame number range where the initial transmission position of the reference time message is located and the first position in the system frame number range where the receiving position is located, a second system frame corresponding to the system frame number range of the previous round in the system frame number range where the receiving position is located is obtained, and the end boundary of the second system frame is determined as the actual reference time position corresponding to the reference time.
For example, if the specified system frame number is 32, if the reference time position corresponding to the reference time generated by the network device side is the end boundary of the system frame with the system frame number of the mth round being 32, and a reference time message is sent on one system frame in the frame number range of (512-1023) of the mth round, and the terminal receives the reference time message on one system frame in the frame number range of (0-511), the terminal determines that the end boundary of the system frame with the system frame number of 32 in the system frame number range of the previous round where the receiving position is located is the actual reference time position.
B23, if the initial sending position of the reference time message is at the second position in the range of the system frame number where the initial sending position is located, and the receiving position is at the second position in the range of the system frame number where the initial sending position is located, acquiring a third system frame corresponding to the range of the system frame number where the receiving position is located, and determining the first boundary of the third system frame as the actual reference time position corresponding to the reference time;
it should be noted that the frame number of the third system frame is the same as the preset system frame number, that is, the frame number of the third system frame is the specified system frame number; the first boundary is a start boundary or an end boundary.
For example, when the first boundary is an end boundary, if the initial transmission position of the reference time message is located at a second position in the system frame number range where the initial transmission position is located, and the receiving position is located at the second position in the system frame number range where the initial transmission position is located, a third system frame corresponding to the system frame number range where the receiving position is located is obtained, and the end boundary of the third system frame is determined as the actual reference time position corresponding to the reference time.
It should be further noted that, the reference time message may further include: the network device generates a first interval between a reference time position corresponding to the reference time and a position of an initial transmission position of the reference time message in the first configuration.
For example, the first interval is a distance K system change cycles between a reference time position corresponding to the reference time generated by the network device and a reference time position corresponding to a system message change cycle in which the initial sending position of the reference time message is located; when the value is a positive value, the reference time position corresponding to the reference time generated by the network equipment is represented and is K periods later than the reference time position corresponding to the system message change period in which the initial sending position of the reference time message is located; for example, the actual reference time position of the reference time generated by the network device is the end boundary of the system message change period N-1, and if the initial transmission position of the reference time message is in the system message change period N, K is-1.
For example, the first interval is a distance K1 sending windows between a reference time position corresponding to the reference time generated by the network device and a reference time position corresponding to a system message sending window where the initial sending position of the reference time message is located;
for example, the first interval is a distance K2 × 1024 system frames between a reference time position corresponding to the reference time and a reference time position corresponding to a paging cycle in which an initial transmission position of the reference time message is located.
In this case, step 102 is further implemented by:
and obtaining the actual reference time position of the redetermined adjustment reference time according to the first interval and the actual reference time position corresponding to the reference time determined according to a first preset rule.
It should be noted that the unit of the first interval corresponds to the unit of the reference time configuration type, that is, the unit of the first interval is a preset period, a preset window, a preset paging period, or a preset system frame;
for example, when the actual reference time position is one period before the position of the initial transmission position of the reference time message in the system message change period, the final actual reference time position is the initial actual reference time position minus one period.
It should be noted that, when the reference time message does not carry the first interval, and when the preset reference time position is the first boundary of the system message change period, preferably, the reference time position corresponding to the reference time generated by the network device is the first boundary of the system message change period where the reference time message is initially sent, and when the first boundary is the start boundary, the reference time position corresponding to the reference time generated by the network device is the start boundary of the system message change period where the reference time message is initially sent. It should be noted that, when the reference time message does not carry the first interval, and the preset reference time position is the first boundary of the system message sending window, the first boundary of the paging cycle, or the first boundary of the system frame corresponding to the preset system frame number, the reference time position corresponding to the reference time generated by the network device is similar to the case where the preset reference time position is the first boundary of the system message change cycle, and is not described herein again.
It should be further noted that, after step 102, the method of the embodiment of the present invention further includes:
and adjusting the time of the terminal in the service cell according to the reference time and the actual reference time position.
Specifically, a preferred embodiment is: and if the time of the terminal at the actual reference time position is not consistent with the reference time, adjusting the time of the terminal in the service cell according to the reference time and the actual reference time position. It should be further noted that the above is only an example of a preferred embodiment of how to adjust the time of the terminal in the serving cell, and other ways of adjusting the time of the terminal in the serving cell also belong to the protection scope of the embodiment of the present invention.
Before step 103, further comprising:
determining a serving cell to which the reference time applies.
Specifically, a first cell is determined as a serving cell to which the reference time is applied;
wherein the first cell is a cell that transmits the reference time message.
Further, the network device may also indicate related cell information for the terminal, and specifically, the reference time message further includes:
cell information of the reference time can be used.
It should be noted that the cell information capable of using the reference time includes at least one of the following information:
c11, identification of cell;
for example, PCI (Physical Cell Identifier); or CGI (Cell global identifier); or a cell ID (serving cell identifier), etc.;
c12, cell group identification;
e.g., Master Cell Group (MCG); or a Secondary Cell Group (SCG).
In this case, the manner of determining the serving cell to which the reference time applies is as follows:
and determining the cell capable of using the reference time indicated in the reference time message as a serving cell applying the reference time.
The serving Cell may be a Primary Cell (PCell), a Secondary Primary Cell (PScell), or a Secondary Cell (SCell);
for example, if the reference time message sent by the network device does not carry "cell information capable of using the reference time", the terminal determines that the cell receiving the reference time message is a serving cell applying the reference time; if the reference time message sent by the network equipment carries 'cell information capable of using the reference time', the terminal determines that the cell indicated in the reference time message is a serving cell applying the reference time.
It should be noted that the embodiment of the present invention is applicable to 5G and subsequent evolution communication systems.
The method of the embodiment of the invention can realize that the reference time is provided for the terminal in a unicast mode, and the network side and the terminal are ensured to have common understanding on the reference time point corresponding to the reference time, thereby improving the synchronization precision.
As shown in fig. 3, an embodiment of the present invention provides a terminal 300, including:
a receiving module 301, configured to receive a reference time message sent by a network device, where the reference time message includes: reference time and indication information of a transmission position of the reference time message;
a determining module 302, configured to determine, according to the indication information, a preset reference time position, and a receiving position of the reference time message, an actual reference time position corresponding to the reference time.
Optionally, the indication information is used to indicate: a position of an initial transmission position of the reference time message in a first configuration.
Further, in the first configuration comprises: when the system message changes the period, the system message sending window, or the paging period, the determining module 302 is configured to:
determining an actual reference time position corresponding to the reference time according to a first preset rule;
wherein the first preset rule comprises one of the following modes:
if the initial sending position of the reference time message is at the first position in the first configuration, determining a first boundary of the first configuration where the receiving position is located as the actual reference time position;
