Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In the related art, the industry recently carries out research on the establishment of 5G unlicensed spectrum and proposes the establishment of supporting independent networking of unlicensed cells. How to transmit the related information of the synchronized broadcast block and the corresponding RMSI is a focus of attention in the industry on unlicensed spectrum design. One possible scheme is that, as shown in fig. 1, there is a symbol interval between the synchronization broadcast block and the related information of the corresponding RMSI in the time domain. Then, the base station needs to perform two detections for the information related to the synchronization broadcast block and the corresponding RMSI (remaining critical system information), and the detections are more frequent. And, the interval of the related information of the synchronized broadcast block and the corresponding RMSI is small, and the coexistence with the Wireless Local Area Network (WLAN) is poor, which does not meet the system requirements of the WLAN.
To solve the above problem, in the present embodiment, the correlation information of a plurality of synchronized broadcast blocks and corresponding RMSIs is taken as the correlation information of a set of synchronized broadcast blocks and RMSIs. The related information of a group of synchronized broadcast blocks and RMSI at a time detects whether the channel is idle, reducing the detection frequency. And the related information of a group of synchronous broadcast blocks and RMSI is sent at one time, so that the time interval is reduced, and the WLAN system can better coexist.
Fig. 2 is a flowchart illustrating a method for transmitting related information of a synchronized broadcast block and an RMSI, which is used for a network access device such as a base station, according to an example embodiment. As shown in fig. 2, the method comprises the following steps 201-202.
In step 201, detecting whether a channel is idle at the current transmission time to transmit a set of synchronization broadcast blocks and related information of RMSI; the related information of the set of synchronized broadcast blocks and the RMSI includes at least related information of one synchronized broadcast block and the corresponding RMSI.
In step 202, when the channel is detected to be idle at the current transmission time, the beam scanning transmits the set of synchronized broadcast blocks and the information related to the RMSI.
In this embodiment, the information related to the plurality of synchronized broadcast blocks and the corresponding RMSI is used as the information related to a set of synchronized broadcast blocks and RMSI. The information related to the synchronized broadcast block and the corresponding RMSI may be a discovery reference signal. The related information of a group of synchronized broadcast blocks and RMSI at a time detects whether the channel is idle, reducing the detection frequency. And the related information of a group of synchronous broadcast blocks and RMSI is sent at one time, so that the time interval is reduced, and the WLAN system can better coexist.
The system may pre-configure a start time domain position of a group of related information of the synchronized broadcast block and the RMSI, and the current transmission time is the start time domain position. For example, in the low frequency band, the starting time domain position is the 3 rd time domain symbol, and the time domain resource length allocated for a set of synchronization broadcast blocks and related information of the RMSI is 10 symbols. Then it is detected whether the channel is free on the time domain symbols 3-13. Detecting whether the channel is idle, comprising: detecting whether the interference energy of the channel at the current sending moment exceeds a preset threshold value, and if not, determining that the channel is idle. The probed channel is a channel within the transmit band.
For another example, in the high frequency band (above 6G), the starting time domain position is 3 rd and 19 th time domain symbols, and the length of the time domain resource allocated for the set of synchronization broadcast blocks and the related information of the RMSI is 10 symbols. Then, whether the channel is idle on the time domain symbols 3-13 is detected, and the current sending time is the 3 rd time domain symbol. If not, the current transmission time instant is changed to the 19 th time domain symbol. Then it is detected whether the channel is free on the time domain symbols 19-29.
In one embodiment, the ratio of the time length of a group of synchronous broadcast blocks and related information of the RMSI to 1ms does not exceed a preset ratio range; the proportion ranges from 60% to 90%.
Wherein, in the proportion range, 68% of equal proportion value can be taken.
In this embodiment, as many synchronization broadcast blocks and corresponding related information of the RMSI as possible form a set of synchronization broadcast blocks and related information of the RMSI, so as to reduce the number of detections of the base station and the transmission delay of the related information of the synchronization broadcast blocks and the RMSI as much as possible. On the other hand, the quantity of the related information of the synchronized broadcast block and the RMSI in a group is not too large, and the related information of the synchronized broadcast block and the RMSI does not occupy too much channel time to affect the transmission of the uplink information. Therefore, the embodiment provides a relatively suitable proportion range, and balances the requirements of all aspects.
In one embodiment, as shown in fig. 3, the one synchronization broadcast block and the related information of the corresponding RMSI are symbol-continuous in the time domain.
Taking L as 4 as an example, L is the maximum number of transmittable synchronized broadcast blocks in a preconfigured period. In the low frequency band of 15K, one synchronized broadcast block occupies 4 time domain symbols, and 2 synchronized broadcast blocks and the related information time slots of the corresponding RMSI are consecutive, occupying 12 time domain symbols in total, forming a group. And transmitting a group of related information of the synchronized broadcast block and the RMSI in one time slot. The starting position of a set of synchronization broadcast blocks and related information of the RMSI in one time slot can be flexibly configured by the base station. In other examples, multiple groups of synchronization broadcast blocks and related information of RMSI may be transmitted in one timeslot, and the larger the number of synchronization broadcast blocks in a group, the larger the transmission gap between groups may be, so as to better coexist with the WLAN system and facilitate uplink information transmission.
Wherein, one synchronous broadcast block occupies 2 time domain symbols or 4 time domain symbols.
When one synchronized broadcast block occupies 4 time domain symbols, for a low frequency band, the related information of the set of synchronized broadcast blocks and the RMSI includes related information of one or 4 synchronized broadcast blocks and corresponding RMSI; for the high frequency band, the related information of the set of synchronized broadcast blocks and the RMSI includes related information of 4 or 8 synchronized broadcast blocks and corresponding RMSI.
When one synchronized broadcast block occupies 2 time domain symbols, for a low frequency band, the related information of the set of synchronized broadcast blocks and the RMSI includes related information of 4 or 8 synchronized broadcast blocks and corresponding RMSI; for the high frequency band, the related information of the set of synchronized broadcast blocks and the RMSI includes related information of 8 or 16 synchronized broadcast blocks and corresponding RMSI.
In one embodiment, as shown in fig. 4, the one synchronization broadcast block is symbol-continuous in the frequency domain with the paging information or with other broadcast information.
The sync broadcast block, the related information of the corresponding RMSI, the paging information, and other broadcast information may constitute one signal block. The broadcast block is synchronized with the paging information or continuous with other broadcast information symbols on the frequency domain, so that the requirement of the system on bandwidth occupation can be met. The occupied bandwidth meets a preset bandwidth proportion threshold (such as 80%) as much as possible.
In one embodiment, as shown in fig. 5, when the related information of the set of synchronized broadcast blocks and the RMSI includes at least two synchronized broadcast blocks, the related information of the RMSI corresponding to the previous synchronized broadcast block in the two synchronized broadcast blocks is located before the two synchronized broadcast blocks in the time domain; the related information of the RMSI corresponding to the latter synchronized broadcast block is located after the two synchronized broadcast blocks in the time domain.
If a group of synchronized broadcast blocks and the related information of the RMSI comprises three or more synchronized broadcast blocks, the related information of the RMSI corresponding to the former part of the synchronized broadcast blocks in the three or more synchronized broadcast blocks is positioned before the two synchronized broadcast blocks in the time domain; and the related information of the RMSI corresponding to the latter part of the synchronous broadcast blocks is positioned after the two synchronous broadcast blocks in the time domain. The former part comprises one or two synchronized broadcast blocks and, correspondingly, the latter part comprises two or one synchronized broadcast block.
The present embodiment provides an implementation manner, for example, a group of synchronized broadcast blocks and related information of RMSI includes two synchronized broadcast blocks, and related information of RMSI corresponding to a previous synchronized broadcast block is located before the group of synchronized broadcast blocks; the related information of the RMSI corresponding to the next sync broadcast block is located after the set of sync broadcast blocks. Of course, the related information of all RMSIs corresponding to the group of synchronized broadcast blocks may be located before the group of synchronized broadcast blocks or located after the group of synchronized broadcast blocks.
In one embodiment, the indication bits preset in the synchronized broadcast block for indicating the RMSI are partially used for indicating the code point information about the RMSI, and the remaining indication bits are reserved.
In the related art, the related information of the synchronized broadcast block and the corresponding RMSI is discontinuous and has symbol intervals, so that there are many possible position relationships, and more indication bits are required to notify the terminal of which position relationship is currently adopted. In this embodiment, symbols are continuous in the time domain between the related information of the synchronized broadcast block and the corresponding RMSI, so that there may be fewer location relationships, and the terminal may be notified of which location relationship is currently used by using fewer indication bits. The remaining portion indicates bit retention.
In one embodiment, the information related to the RMSI includes at least one of: data information of the RMSI and a control resource set (CORESET) that schedules the RMSI. Data information of the RMSI may be carried by a PDSCH (physical downlink shared channel).
The above embodiments can be freely combined as needed.
