Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a terminal for sending and receiving synchronous resource indication information.
Background
In the 5g NR v2x system, direct communication is performed between terminals using a PC5 port (sidlink). Before the transmission of service data, synchronization is established between two terminals that first need to communicate at the PC5 port (sidlink). The method for establishing synchronization is that one terminal A sends synchronization and broadcast signals, the other terminal B receives the synchronization and broadcast signals sent by the terminal A, and once the terminal B receives and demodulates the synchronization and broadcast signals successfully, the two terminals can establish synchronization so as to prepare for the next direct communication.
The synchronization signal of the NR UU port is carried by SSB block (Synchronization Signal Block ). Each Slot carries 2 SSB blocks and the PSS (Primary Synchronization Signal ) and SSS (Secondary Synchronization Signal, secondary synchronization signal) signals have no time domain repetition mechanism.
In order to complete Beam measurement and Beam selection, the SSB of the NR UU needs to perform Beam scanning (Beam scanning), where Beam scanning refers to that the base station transmits SSB once in each possible Beam direction in a certain time interval (5 ms), then the terminal measures the SSB signal strength of each Beam and reports the measurement result to the base station, and the base station selects the most suitable Beam to transmit data to the terminal according to the measurement result reported by the terminal. The number of directions in which beam scanning is required varies depending on the carrier frequency and subcarrier spacing. The maximum values of the SSB beam scanning candidate directions in different carrier frequency ranges are respectively as follows: the number of beam scanning directions actually configured cannot exceed this maximum value, 4/8/64.
In the existing LTE V2X technology, at most 3 synchronization subframes are configured on the sip direct link every 160ms, and the UE performs transmission and reception of the sip synchronization signal and the broadcast information on the synchronization subframes, and does not perform beam scanning when the UE transmits and receives the synchronization signal and the broadcast information on the synchronization subframes. With the advent of 5G NR, the internet of vehicles technology was further developed to meet the needs of new application scenarios. The 5G NR supports a larger bandwidth, flexible configuration of subcarrier spacing, and transmission of synchronization signals and broadcast information in the form of SSB beam scanning or beam repetition. The design of the NR V2X physical layer structure brings new challenges, and the transmission and reception of the synchronization signal and the broadcast information performed by the original UE on the synchronization subframe needs to be redesigned, and an SSB beam scanning or beam repetition mechanism needs to be introduced to meet the requirements of NR V2X.
After the SSB beam scanning or beam repetition mechanism is introduced into the NR V2X, a plurality of synchronization signal blocks are sent in one synchronization period, and a plurality of synchronization resource sets are configured in one synchronization period, so that how to make the terminal determine the positions of the synchronization resource sets according to the received plurality of synchronization signal blocks under the complex condition of configuring the plurality of synchronization resource sets, thereby completing synchronization timing becomes an urgent problem to be solved.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a method for sending synchronous resource indication information, which is applied to a terminal, and the method includes:
In the embodiment of the invention, the SSB is a through link synchronization signal block S-SSB, the PBCH is a physical through link broadcast channel PSBCH, and the synchronization resource is a through link synchronization resource and is used for transmitting or receiving the through link synchronization signal block S-SSB.
Specifically, in order to notify the terminal of the synchronization resource indication information, the physical broadcast channel PBCH needs to carry the synchronization resource indication information. The synchronization resource indication information may be carried and sent by at least one of the physical broadcast channel PBCH payload and the demodulation reference signal DMRS corresponding to the physical broadcast channel PBCH. That is, the following three ways may be adopted:
mode 1: the synchronous resource indication information is carried by a Physical Broadcast Channel (PBCH) load;
mode 2: the synchronous resource indication information is carried by a demodulation reference signal (DMRS) corresponding to a Physical Broadcast Channel (PBCH);
mode 3: the synchronization resource indication information carries a part of information through the Physical Broadcast Channel (PBCH) load, and the rest information is carried by a demodulation reference signal (DMRS) corresponding to the Physical Broadcast Channel (PBCH).
The embodiment adopts the notification mode, and can flexibly configure the synchronous resource indication information by changing the content carried by the physical broadcast channel PBCH, namely, the content of different synchronous resource indication information can be configured according to different scenes.
As shown in the above embodiment, the synchronization resource indication information may also be notified to the terminal in a preconfigured manner. Namely: the synchronous resource indication information is preset, and the numerical value of the configured synchronous resource indication information is directly read after the terminal is started without signaling notification.
When the synchronous resource indication information is configured in a preconfigured mode, one synchronous resource or one S-SSB belongs to a first synchronous resource set, a second synchronous resource set or a third synchronous resource set. That is, for any one of the synchronization resources, which synchronization resource set it belongs to, is preconfigured, so that signaling overhead caused by signaling the attribution relationship between each synchronization resource and the three synchronization resource sets is avoided. This embodiment adopts this notification mode and does not occupy the signaling overhead of the physical broadcast channel PBCH.
In an alternative embodiment of the present invention, the synchronization resource indication information occupies 1 bit or 2 bits.
When the system is configured with at most two synchronous resource sets, the synchronous resource indication information occupies 1 bit. When the synchronization resource indication information occupies 1 bit, the first S-SSB is indicated to belong to the first synchronization resource set or the second synchronization resource set. When the system configures two synchronous resource sets for the terminal, the terminal uses one synchronous resource set to send the synchronous signal block SSB, and the terminal uses the other synchronous resource set to receive the synchronous signal block SSB.
In an optional implementation manner, a method for sending synchronous resource indication information includes: and sending a first synchronization signal block SSB, wherein the first SSB comprises a physical broadcast channel PBCH, and the first SSB is configured or carried with synchronization resource indication information in a first mode, the synchronization resource indication information indicates that the first SSB belongs to a first synchronization resource set or a second synchronization resource set, and the synchronization resource indication information occupies 1 bit. The first synchronization resource set and the second synchronization resource set each include at least one synchronization resource, preferably, the first synchronization resource set and the second synchronization resource set may each include 2, 4, 6, 8, 16, 32 or 64 synchronization resources, one synchronization resource occupies one time slot in the time domain, and occupies 11 resource blocks RB in the frequency domain.
As shown in fig. 2, a schematic diagram of time domain locations is sent for the S-SSB set at 120KHz subcarrier spacing. One synchronization period is 160ms and includes 160 subframes in total. With 120KHz, a subframe contains 8 slots, one slot being represented by each small vertical cell. The small columns with the pattern represent the synchronization time slots, i.e. the time slots containing the S-SSB. The white small bars are not synchronous slots, i.e. represent slots not containing S-SSBs, and the 1 set of synchronous resources comprises 8S-SSBs, and two sets of synchronous resources in fig. 2 are respectively represented by different patterns, the first set of synchronous resources is represented by a first pattern shown in the figure, and the second set of synchronous resources is represented by a second pattern shown in the figure. The currently received S-SSB is represented as a patterned S-SSB in subframe 3 in fig. 2.
Taking the receiving end as an example, the synchronization resource indication information indicates that the currently received S-SSB (S-SSB of the first pattern) belongs to the first synchronization resource set to the receiving end. If there is no synchronization resource indication information, for the receiving end, after the terminal receives the S-SSB of the first pattern in fig. 2, the receiving end does not know that the first pattern S-SSB belongs to the first synchronization resource set, or the second synchronization resource set, and cannot determine the synchronization resource set position.
After the synchronization resource indication information is notified, the receiving end knows that the first pattern S-SSB belongs to the first synchronization resource set, and can calculate the position of the synchronization resource set according to the information such as DFN (Direct Frame Number, direct radio frame number), interval between two S-SSBs, S-SSB index number and the like by using the offset 1 corresponding to the first synchronization resource set.
The embodiment adopts the notification mode of the synchronous resource indication information, and the terminal can know which synchronous resource set the S-SSB currently received belongs to, so that the terminal can determine the synchronous resource set according to the synchronous resource indication information and other information, and the terminal can complete the direct link synchronization process according to the related information of the synchronous signal block received by the terminal. And the synchronous resource indication information only occupies 1 bit, so that the signaling overhead is small.
In another alternative implementation, when the system is configured with at most three sets of synchronization resources, the synchronization resource indication information occupies 2 bits; when the synchronization resource indication information occupies 2 bits, the first S-SSB is indicated to belong to a first synchronization resource set, a second synchronization resource set or a third synchronization resource set. When the system configures three synchronous resource sets for the terminal, the terminal uses one synchronous resource set to send the synchronous signal block SSB, the terminal uses the other synchronous resource set to receive the synchronous signal block SSB, and the terminal uses the third synchronous resource set to send the synchronous signal block SSB when the terminal is directly synchronous with the GNSS.
The method for transmitting the synchronous resource indication information comprises the following steps: and sending a first synchronization signal block SSB, wherein the first SSB comprises a physical broadcast channel PBCH, and the first SSB is configured or carried with synchronization resource indication information in a first mode, wherein the synchronization resource indication information indicates that the first SSB belongs to a first synchronization resource set, a second synchronization resource set or a third synchronization resource set. The synchronization resource indication information occupies 2 bits. The first set of synchronization resources, the second set of synchronization resources and the third set of synchronization resources each comprise at least one synchronization resource, preferably, the first set of synchronization resources and the second set of synchronization resources and the third set of synchronization resources may each comprise 2, 4, 6, 8, 16, 32 or 64 synchronization resources, one synchronization resource occupies one time slot in the time domain and occupies 11 resource blocks RB in the frequency domain.
As shown in fig. 3, a schematic diagram of time domain locations is sent for the S-SSB set at 120KHz subcarrier spacing. One synchronization period is 160ms and includes 160 subframes in total. With 120KHz, a subframe contains 8 slots, one slot being represented by each small vertical cell. The small columns with the pattern represent the synchronization time slots, i.e. the time slots containing the S-SSB. The white small bars are not synchronous time slots, i.e. represent time slots not containing S-SSB, the 1 synchronous resource set comprises 8S-SSB, three synchronous resource sets are respectively represented by different patterns in figure 3, the first synchronous resource set is represented by a first pattern, the second synchronous resource set is represented by a second pattern, and the third synchronous resource set is represented by a third pattern. The currently received S-SSB is represented by the first pattern S-SSB in subframe 3 in fig. 3, i.e., the S-SSB of the second synchronization resource represented by the first pattern.
Taking the receiving end as an example, the synchronization resource indication information indicates that the currently received S-SSB (the first pattern S-SSB) belongs to the first synchronization resource set to the receiving end. If there is no synchronization resource indication information, for the receiving end, after the terminal receives the first pattern S-SSB in fig. 3, the receiving end does not know that the first pattern S-SSB belongs to the first synchronization resource set, the second synchronization resource set, or the third synchronization resource set, and cannot determine the synchronization resource set position.
After the synchronous resource indication information is notified, the receiving end knows that the first pattern S-SSB belongs to the first synchronous resource set, and the offset 1 corresponding to the first synchronous resource set can be used to calculate the position of the synchronous resource set according to the information such as the DFN, the interval between the two S-SSBs, the S-SSB index number and the like.
The embodiment adopts the notification mode of the synchronous resource indication information, and the terminal can know which synchronous resource set the S-SSB currently received belongs to, so that the terminal can determine the synchronous resource set according to the synchronous resource indication information and other information, and the terminal can complete the direct link synchronization process according to the related information of the synchronous signal block received by the terminal. At the moment, the system can configure three synchronous resource sets at most, and the number of the synchronous resource sets which can be configured by the system is more flexible.
