Detailed Description
In order to facilitate understanding of the technical solutions of the embodiments of the present invention, the following description will be made of related technologies related to the embodiments of the present invention.
1) Unlicensed spectrum
Unlicensed spectrum is a nationally and regionally divided spectrum that may be used for communication by radio devices, and is generally considered a shared spectrum, i.e., a spectrum that may be used by communication devices in different communication systems as long as the regulatory requirements set by the country or region on the spectrum are met, without requiring a proprietary spectrum license to be applied to the government. In order for various communication systems using unlicensed spectrum for wireless communication to coexist friendly on the spectrum, some countries or regions stipulate regulatory requirements that must be met using unlicensed spectrum. For example, in european regions, the communication device follows the LBT principle, that is, before the communication device transmits signals on the unlicensed spectrum channel, it needs to perform channel sensing first, and only when the channel sensing result is that the channel is idle, the communication device can transmit signals; if the channel sensing result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot transmit signals. In order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the unlicensed spectrum Channel cannot exceed the Maximum Channel Occupancy Time (MCOT). For another example, to avoid sub-band interference to the signal transmitted on the unlicensed spectrum channel and to improve the detection accuracy of the communication device when detecting the unlicensed spectrum channel, the signal transmitted on the unlicensed spectrum channel needs to occupy at least a certain proportion of the channel bandwidth, for example, the 5GHz band is 80% of the channel bandwidth occupied by the signal, and the 60GHz band is 70% of the channel bandwidth occupied by the signal. For another example, in order to avoid that the power of a signal transmitted on a channel of the unlicensed spectrum is too large, which affects the transmission of other important signals on the channel, such as radar signals, etc., regulations stipulate the maximum power spectral density at which a communication device transmits signals using the channel of the unlicensed spectrum.
2) Network architecture

Fig. 1 is a first flowchart illustrating a method for transmitting access information according to an embodiment of the present invention, as shown in fig. 1, the method for transmitting access information includes:
step 101: the base station performs an LBT operation.
Step 102: and if the transmission channel is successfully acquired based on the LBT result, the first SSB is sent according to the period of the first SSB.
Step 103: deferring or not transmitting the first SSB if it is determined, based on the LBT result, that acquisition of the transport channel is not successful.
Wherein the first SSB comprises a control resource set of SIB1 for terminal initial access.
In the embodiment of the present invention, if it is determined based on the LBT result that the transmission channel is not successfully acquired, the following two situations may occur:
the first condition is as follows: the base station does not transmit the first SSB.
Case two: the base station defers from transmitting the first SSB.
For the first case: if the base station does not send the first SSB, the terminal does not receive the first SSB, and thus the SIB 1. Further, if the terminal does not receive the first SSB, the terminal determines whether the first SSB is not transmitted because of an LBT operation.
For the second case:
1) and if the base station defers to send the first SSB, the base station sends first indication information, wherein the first indication information is used for indicating that the position of the first SSB is shifted.
In an embodiment, the first indication information is carried on 1 bit in the MIB.
When the value of 1 bit in the MIB is a first value (e.g. 1), the first indication information is used to indicate that the position of the first SSB is shifted;
when the value of 1 bit in the MIB is a second value (e.g., 0), the first indication information is used to indicate that the position of the first SSB is not shifted.
2) The first SSB carries a control resource set of RMSI; if the base station defers to send the first SSB, the base station updates the control resource set of the RMSI carried in the first SSB, or the base station does not update the control resource set of the RMSI carried in the first SSB.
2.1) when the base station updates the control resource set of the RMSI carried in the first SSB, the base station sends second indication information, where the second indication information is used to indicate whether the control resource set of the RMSI in the first SSB is updated because the location of the first SSB is shifted.
In one embodiment, the second indication information is configured by physical layer signaling; or, the second indication information is configured through high-layer signaling; alternatively, the second indication information is preconfigured.
2.2) if the base station updates the control resource set of the RMSI carried in the first SSB, the terminal does not need to calculate the original position of the first SSB; if the base station updates the control resource set of the RMSI carried in the first SSB, the terminal does not need to calculate the original position of the first SSB;
here, if the base station updates the set of control resources of the RMSI carried in the first SSB, the terminal reads the set of control resources of the RMSI and calculates a time-frequency resource location for receiving the RMSI based on the current location and the location offset of the first SSB.
Here, if the base station does not update the set of control resources of the RMSI carried in the first SSB, the terminal reads the set of control resources of the RMSI and calculates the original location of the first SSB, and calculates the location of the time-frequency resources for receiving the RMSI based on the original location and the location offset of the first SSB.
2.3) if the base station supports the resetting of the control resource set of the RMSI, the base station sends third indication information, wherein the third indication information is used for indicating that the position of the control resource set of the RMSI is obtained according to the position of the first SSB after the deviation.
Here, if the base station supports resetting the value of the RMSI coreset, i.e. 1 is reselected from several offset values 0, 2, 5, 7 defined in the existing 36.213, the value that the base station needs to indicate to the terminal RMSI coreset is derived from the offset position.
2.4) if the base station updates the control resource set of the RMSI carried in the first SSB, when multiple SSBs are merged through a physical layer, the first SSB carrying the updated control resource set of the RMSI does not perform a merging operation.
2.5) the base station transmitting the control resource set of the RMSI and the PDSCH of SIB1 in a time division multiplexing manner, wherein if the PDSCH of SIB1 is not transmitted in an original position due to LBT operation, the base station increases the number of transmissions of the PDSCH of SIB 1.
Further, the transmission position of the PDSCH of the added SIB1 is periodic or aperiodic.
Here, if the terminal receives the PDCCH according to the resource location indicated by the RMSI coreset, in the case where the PDCCH (RMSI) and the PDSCH (SIB1) are transmitted in a Time Division Multiplexing (TDM) manner, there is a possibility that the SIB1 base station at the original location is not transmitted on the PDSCH due to the LBT operation. For this reason, the number of transmissions of the PDSCH (SIB1) is increased, and the increased transmission position may be aperiodic and is not limited to periodic transmission.
Those skilled in the art will appreciate that the order of execution of the above steps 102 and 103 is not limited.
Fig. 2 is a second flowchart illustrating a method for transmitting access information according to an embodiment of the present invention, where as shown in fig. 2, the method for transmitting access information includes:
step 201: the method comprises the steps that a terminal receives a first SSB sent by a base station based on LBT operation, wherein if the base station determines to acquire a transmission channel successfully based on LBT results, the first SSB is sent according to the period of the first SSB; deferring or not transmitting the first SSB if the base station determines that the acquisition of the transmission channel is not successful based on the LBT result.
Wherein the first SSB comprises a set of control resources of the SIB1 for initial access by the terminal.
In the embodiment of the present invention, if it is determined based on the LBT result that the transmission channel is not successfully acquired, the following two situations may occur:
the first condition is as follows: the base station does not transmit the first SSB.
Case two: the base station defers from transmitting the first SSB.
For the first case: if the base station does not send the first SSB, the terminal does not receive the first SSB, and thus the SIB 1.
Further, if the terminal does not receive the first SSB, the terminal determines whether the first SSB is not transmitted because of an LBT operation.
For the second case:
1) and if the base station postpones the sending of the first SSB, the terminal receives first indication information sent by the base station, wherein the first indication information is used for indicating that the position of the first SSB is deviated.
In an embodiment, the first indication information is carried on 1 bit in the MIB.
In an embodiment, when a value on 1 bit in the MIB is a first value, the first indication information is used to indicate that a position of the first SSB is shifted;
and when the value of 1 bit in the MIB is a second value, the first indication information is used to indicate that the position of the first SSB is not shifted.
2) The first SSB carries a control resource set of RMSI; if the base station defers to send the first SSB, the base station updates the control resource set of the RMSI carried in the first SSB, or the base station does not update the control resource set of the RMSI carried in the first SSB.
2.1) under the condition that the base station updates the control resource set of the RMSI carried in the first SSB, the terminal receives second indication information sent by the base station, where the second indication information is used to indicate whether the control resource set of the RMSI in the first SSB is updated because the location of the first SSB is shifted.
In one embodiment, the second indication information is configured by physical layer signaling; or, the second indication information is configured through high-layer signaling; alternatively, the second indication information is preconfigured.
2.2) if the base station updates the control resource set of the RMSI carried in the first SSB, the terminal does not need to calculate the original position of the first SSB; if the base station does not update the set of control resources of the RMSI carried in the first SSB, the terminal needs to calculate the original location of the first SSB.
Here, if the base station updates the set of control resources of the RMSI carried in the first SSB, the terminal reads the set of control resources of the RMSI and calculates a time-frequency resource location for receiving the RMSI based on the current location and the location offset of the first SSB.
Here, if the base station does not update the set of control resources of the RMSI carried in the first SSB, the terminal reads the set of control resources of the RMSI and calculates the original location of the first SSB, and calculates the location of the time-frequency resources for receiving the RMSI based on the original location and the location offset of the first SSB.
