Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The period of the prior S-SS/PSBCH block (hereinafter referred to as S-SSB) is 160ms, and the number of S-SSB in one periodS-SSB slot offset(I.e., the slot offset between the first slot at the beginning of the cycle and the first S-SSB occurring during the cycle), S-SSB slot spacingThe slot intervals between S-SSBs are (pre) configured by higher layer parameters, as shown in fig. 1.
Indexing of S-SSB in S-SSB periodThe bearer is 7 bits in total in the PSBCH. At present, in SIDELINK FR frequency bands, 64S-SSBs can be configured in one S-SSB period at most.
One S-SSB occupies 13 OFDM symbols (normal CP) or 11 OFDM symbols (extended CP) in the time domain, including a direct link primary synchronization signal (SIDELINK PRIMARY synchronization signal, S-PSS), a direct link secondary synchronization signal (sidelink secondary synchronization signal, S-SSS), and a PSBCH. One S-SSB occupies 132 consecutive REs (i.e., 11 PRBs) in the frequency domain. Taking normal CP as an example, the slot structure of one S-SSB is shown in fig. 2.
In the Uu port at present, the terminal and the base station are both communication parties, and all terminals need to be synchronized to a service cell (SERVING CELL) to obtain information such as downlink synchronization and cell configuration. The synchronization mechanism of the sidelink is greatly different from that of the Uu port, wherein the biggest difference is that the purpose of synchronization of the terminals is mainly to synchronize to a certain synchronization source so as to acquire timing and TDD configuration (the terminals must acquire the TDD configuration to further determine the resources of the transceiving resource pool), each terminal maintains a set of timing, and the two parties for performing the sidelink communication are not necessarily synchronized to each other or to the same synchronization source. The method comprises the following steps:
1) From the point of view of searching for synchronization sources by the terminal, NR SIDELINK supports multiple types of synchronization sources including global satellite navigation system (Global Navigation SATELLITE SYSTEM, GNSS), cell, reference terminal (REFERENCE UE), the terminal can obtain timing information from either synchronization source, and NR SIDELINK supports two synchronization priority types, GNSS-based and gNB/eNB-based, the sidelink synchronization priority type of a certain terminal being (pre) configured. The two synchronization priorities are defined differently for each synchronization source, as shown in table 1. Taking the GNSS-based synchronization priority as an example, the GNSS itself has the highest priority P0, and when one terminal can directly synchronize to the GNSS, its synchronization priority is P1, and so on. When a certain terminal can search a plurality of synchronous sources, a synchronous source with high priority is preferentially selected as a reference synchronous source, and if the priority of the synchronous sources is the same, a synchronous source with high RSRP is preferentially selected as the reference synchronous source.
TABLE 1
2) The transmission trigger conditions and transmission rules of the direct link synchronization signal (SLSS) are defined in detail from the point of view of the terminal transmitting the synchronization signal NR SIDELINK, not all terminals will transmit SLSS, and the terminal will transmit SLSS if and only if a series of conditions specified by the protocol are met. For example, a certain terminal performs sidelink communication in the frequency band out-of-coverage (for example, the communication frequency band is ITS band), and selects GNSS or cell as the synchronization source, if the terminal is in RRC connected state and SLSS transmission domain in DEDICATED SIGNALING is set to 0, the terminal will transmit SLSS. When the terminal needs to perform the sidelink communication and the SLSS sending condition defined by the protocol is satisfied, SLSS is sent according to a certain rule, as shown in table 2 (taking GNSS-based synchronization priority as an example):
TABLE 2
The existing S-SSB only supports the synchronization function, and does not support the beam management function. If the beam management function is to be supported, the following points are needed for enhancement:
1. In terms of S-SSB Time domain resources, the existing protocol defines three sets of Time domain resource configurations (namely Time Allocation1, 2 and 3) whether the existing Time domain resources are needed to be multiplexed or new Time domain resources are defined, namely how to design the S-SSB Time domain resources for beam management;
2. The terminal for beam management may transmit the S-SSB for beam management using the existing time domain resources assuming that the existing time domain resources are multiplexed, but the contents transmitted on the opportunity (i.e., the instance) of SLSS ID and the multiple SSBs transmitted in the S-SSB period in the existing protocol cannot guarantee the support of the beam management function.
That is, the S-SS/PSBCH block is used as a measurement reference signal in beam management, and what design is needed for the S-SS/PSBCH block to realize beam measurement between FR2 transceiver terminals is a problem to be solved.
The invention provides a time domain resource determining method, a device, a terminal and a medium aiming at the technical problems. The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.
Fig. 3 is a schematic flow chart of a time domain resource determining method according to an embodiment of the present invention. The method can specifically comprise the following steps:
Step 301, determining a direct link synchronization signal/physical direct link broadcast channel block S-SS/PSBCH block time domain resource, where the S-SS/PSBCH block is used to calculate reference signal received power RSRP and/or signal-to-interference-plus-noise ratio SINR;
wherein the S-SS/PSBCH block time domain resource comprises one of the following:
A first S-SS/PSBCH block time domain resource; the first S-SS/PSBCH block time domain resource is used for transmitting direct link synchronization information;
The system comprises a first S-SS/PSBCH block time domain resource, a second S-SS/PSBCH block time domain resource, a third S-SS/PSBCH block time domain resource, a fourth S-SS/PSBCH block time domain resource and a third S-SS/PSBCH block time domain resource, wherein the first S-SS/PSBCH block time domain resource is used for transmitting direct link synchronization information, and the fourth S-SS/PSBCH block time domain resource is used for calculating RSRP and/or SINR;
And the third S-SS/PSBCH block time domain resource at least comprises a fourth S-SS/PSBCH block time domain resource for calculating RSRP and/or SINR.
It should be noted that, the execution body of the method of the present invention is a terminal, and the terminal supports a beam management function. The S-SS/PSBCH block is used for calculating Reference Signal Received Power (RSRP) and/or signal to interference plus noise ratio (SINR), that is, the S-SS/PSBCH block is a measurement reference signal used as beam management.
Wherein, it should be understood that the first S-SS/PSBCH block time domain resource is the S-SS/PSBCH block time domain resource multiplexing the prior synchronous information of the transmission direct link, thus saving the cost of the S-SS/PSBCH block time domain resource.
Referring to fig. 4, the second S-SS/PSBCH block time domain resource is a part of S-SS/PSBCH block time domain resources multiplexing existing S-SS/PSBCH block time domain resources for transmitting direct link synchronization information, and a part of S-SS/PSBCH block time domain resources newly added (newly defined) for calculating RSRP and/or SINR, so that complexity of S-SS/PSBCH block design can be reduced, and S-SS/PSBCH block time domain resource overhead can be saved to some extent. It should be noted that, with the 7bit slot index indication in the full PSBCH, 128 positions (i.e., positions corresponding to 128S-SS/PSBCH block time domain resources) are indicated at most, where 64 positions multiplex the existing S-SS/PSBCH block time domain resources for transmitting the direct link synchronization information, and the newly added up to 64 positions are defined as S-SS/PSBCH block time domain resources for calculating RSRP and/or SINR.
The third S-SS/PSBCH block time domain resources are all newly added (newly defined) S-SS/PSBCH block time domain resources for calculating RSRP and/or SINR, so that an optimal design can be performed for beam management without backward compatibility problems.
According to the method provided by the embodiment of the invention, the S-SS/PSBCH block time domain resource used for transmitting the direct link synchronization information is multiplexed or partially multiplexed, or the brand new S-SS/PSBCH block time domain resource used for beam management is designed, so that the beam measurement between FR2 receiving and transmitting terminals can be realized when the S-SS/PSBCH block is used as a measurement reference signal in the beam management.
As an alternative implementation, the step 301 may specifically include:
Acquiring configuration information, wherein the configuration information comprises at least one of the following:
A period;
The number of the S-SS/PSBCH blocks is the same as or different from the number of the S-SS/PSBCH blocks used for transmitting the direct link synchronization information;
The system comprises an S-SS/PSBCH block time interval, a transmission buffer and a transmission buffer, wherein the S-SS/PSBCH block time interval is the same as or different from the time interval of an S-SSB used for transmitting direct link synchronization information;
and determining the S-SS/PSBCH block time domain resource according to the configuration information.
It should be noted that, whether the first S-SS/PSBCH block time domain resource (multiplexing existing S-SS/PSBCH block time domain resources for transmitting direct link synchronization information), the second S-SS/PSBCH block time domain resource (partially multiplexing existing S-SS/PSBCH block time domain resources for transmitting direct link synchronization information), or the third S-SS/PSBCH block time domain resource (newly added (newly defined) S-SS/PSBCH block time domain resources for calculating RSRP and/or SINR) is determined according to the acquired configuration information.
It should be noted that, in order not to affect the judgment of the downlink timing by the terminal that does not support the beam management, for the receiving and transmitting terminal that performs the beam management, different periods, the number of S-SS/PSBCH blocks, or the interval n_interval of S-SS/PSBCH blocks may be additionally configured to implement different understandings of the measurement behavior, and to implement the receiving and transmitting beam measurement.
There are two configurations, specifically as follows:
A configuration period (period for beam management for BM) or the number of S-SS/PSBCH blocks is configured. At this time, the configuration period can be further shortened, so that the receiving and transmitting sides can acquire beam measurement and pairing information more quickly.
Referring to fig. 5, in this configuration, a transmitting terminal performs polling of a transmission beam in one period, a receiving terminal fixes a reception beam in one period, and performs reception beam polling for a plurality of periods.
For example, in fig. 5, one for BM period is 80ms, the transmitting terminal transmits S-SS/PSBCH blocks with corresponding transmission beams (oval in the figure) at each S-SS/PSBCH block time domain resource position in the period (rectangle in the figure), which is called polling of transmission beams, the receiving terminal receives S-SS/PSBCH blocks with fixed reception beams (reception beams a) in the period, then performs transmission beam measurement and obtains measurement results (RSRP and/or SINR), then still transmits S-SS/PSBCH blocks with corresponding transmission beams at each S-SS/PSBCH block time domain resource position in the period (rectangle in the figure) for the next period, the receiving terminal receives S-SS/PSBCH blocks with fixed reception beams (reception beams B) in the period, then performs transmission beam measurement and obtains measurement results (RSRP and/or SINR), then determines one of two sets of measurement results with better signal quality, and the corresponding reception beam in the set corresponds to the highest measurement value as the optimal transceiving beam for the transmitting terminal.
And secondly, configuring an S-SS/PSBCH block time interval. At this time, the transmitting terminal performs repeated transmission of the same beam first so that the receiving terminal performs reception beam polling, and then the transmitting terminal performs transmission polling of a plurality of beams, and the receiving terminal performs transmission beam measurement. See fig. 6 for details.
Configuration two differs from configuration one in that which of the transmitting terminal and the receiving terminal performs beam polling first. The optimal transceiving beam pair of the transceiving terminal can be determined through beam measurement.
It should be noted that, the configuration one and the configuration two may be configured at the same time, so that the period for beam management is reduced, and repeated transmission may be realized.
It should be noted that, the schemes of the first S-SS/PSBCH block time domain resource and the second S-SS/PSBCH block time domain resource reuse the existing S-SS/PSBCH block time domain resource for transmitting the direct link synchronization information, which means that, on the S-SS/PSBCH block time domain resource for transmitting the direct link synchronization information, there may be a terminal (legacy UE) that does not support beam management to acquire downlink timing, and the sequence design of the S-PSS/S-SSs of the S-SS/PSBCH block depends on the synchronization source priority of the terminal transmitting the S-SS/PSBCH block (may also be referred to as S-SSB) and the network coverage situation where the terminal is located. Meanwhile, for a terminal supporting beam management, S-SS/PSBCH block is a pair measurement, and the sequence design of S-PSS/S-SSS needs to embody the identity of a receiving and transmitting terminal, so that the beam measurement and pairing of the S-SS/PSBCH block and the S-PSS/S-SSS are realized.
Thus, in an alternative embodiment, the S-SS/PSBCH block time domain resources include the first S-SS/PSBCH block time domain resources or the second S-SS/PSBCH block time domain resources, and the generation of the wrapping code sequence of the demodulation reference signal DMRS for the PSBCH is initialized by a first identity, or the generation of the wrapping code sequence for the PSBCH is initialized by a first identity, which is determined based on the identity of the terminal.
The influence of the embodiment on the legacy UE is that when the legacy UE reads the S-SS/PSBCH block sent by the terminal supporting beam management, synchronization cannot be obtained correctly because PSBCH cannot be resolved, and then other synchronization sources in the area are searched continuously, so that ambiguity is avoided.
In an alternative embodiment, the S-SS/PSBCH block time domain resource includes a third S-SS/PSBCH block time domain resource, and the direct link synchronization identifier of the S-SS/PSBCH block is determined based on the identity of the terminal. Compared with the embodiment that the S-SS/PSBCH block time domain resources include the first S-SS/PSBCH block time domain resources and the S-SS/PSBCH block time domain resources include the second S-SS/PSBCH block time domain resources, in this embodiment, all the S-SS/PSBCH block time domain resources are newly added S-SS/PSBCH block time domain resources for calculating RSRP and/or SINR, so that the backward compatibility limit of the S-SS/PSBCH block design does not exist, the optimization design can be performed for beam management, that is, the direct link synchronization identifier of the S-SS/PSBCH block can be determined based on the terminal identity identifier, so that the receiving terminal performing beam management can intuitively identify the S-SS/PSBCH block for beam management sent by the transmitting terminal.
It should be noted that, the schemes of the second S-SS/PSBCH block time domain resource and the third S-SS/PSBCH block time domain resource both relate to newly added (newly defined) S-SS/PSBCH block time domain resources for calculating RSRP and/or SINR, and there are two multiplexing modes with S-SS/PSBCH block time domain resources for transmitting direct link synchronization information, one is frequency division multiplexing FDM with S-SS/PSBCH block time domain resources for transmitting direct link synchronization information, and the other is time division multiplexing TDM with S-SS/PSBCH block time domain resources for transmitting direct link synchronization information. TDM is prioritized over FDM from the terminal capability and implementation point of view. Because if it is considered that FDM may occur that a transmitting terminal needs to transmit both S-SS/PSBCH blocks for transmitting direct link synchronization information and S-SS/PSBCH blocks for calculating RSRP and/or SINR on the same time domain resource, their beam directions may be different, whether or not it is possible to transmit such information depends on the terminal antenna architecture and capability (similar to Uu, SSB different beams are TDM), at this time it may be necessary to consider a priority relationship between S-SS/PSBCH blocks for transmitting direct link synchronization information and S-SS/PSBCH blocks for calculating RSRP and/or SINR, etc., based on which the embodiment of the present invention adopts time division multiplexing.
That is, in an optional embodiment, the S-SS/PSBCH block time domain resources include the second S-SS/PSBCH block time domain resource or the third S-SS/PSBCH block time domain resource, and the fourth S-SS/PSBCH block time domain resource is located in a first resource pool, where the first resource pool is a direct link resource pool dedicated to the first frequency band and the second resource pool is a direct link communication resource pool.
The embodiment considers the backward compatibility of the time domain resources of the resource pool determined by the terminal, and the fourth S-SS/PSBCH block time domain resources, namely the newly added (newly defined) S-SS/PSBCH block time domain resources for calculating RSRP and/or SINR, are positioned in a direct link resource pool dedicated to a first frequency band (optionally, the first frequency band is an FR2 frequency band) and are time division multiplexed with a second resource pool (namely, a resource pool of legacy UE), so that the determination of the resource pool and the resource selection of the terminal (legacy UE) which does not support beam management are not influenced.
In another optional embodiment, the S-SS/PSBCH block time domain resource includes the second S-SS/PSBCH block time domain resource or the third S-SS/PSBCH block time domain resource, and the fourth S-SS/PSBCH block time domain resource is located in or outside a third resource pool, where the third resource pool is a direct link resource pool supporting a terminal of the first frequency band.
This embodiment does not consider the backward compatibility of the terminal determining the time domain resources of the resource pool, i.e. the terminal (legacy UE) which does not support beam management by default only works in the FR1 frequency band, then the time domain resources used by the fourth S-SS/PSBCH block are located in or outside the direct link resource pool of the terminal supporting the first frequency band (optionally the first frequency band is the FR2 frequency band).
In an alternative embodiment, the S-SS/PSBCH block time domain resources include the second S-SS/PSBCH block time domain resources, and the low N1 bits in the slot index indication of the PSBCH are used to indicate the slot index of the first S-SS/PSBCH block time domain resources, and the high N2 bits are used to indicate the slot index of the fourth S-SS/PSBCH block time domain resources.
It should be noted that, for the scheme of the second S-SS/PSBCH block time domain resource, since the maximum S-SS/PSBCH block number is extended from 64 to 128 and legacy UE can only read 64 positions therein, in consideration of backward compatibility, the embodiment designs the sending behavior of the sending terminal and the indication manner of the 7bit slot index in the PSBCH. The method comprises the steps that a sending terminal sends different beams at the S-SS/PSBCH block time domain resource position for transmitting the direct link synchronization information, so that a receiving terminal carries out sending beam selection, and the same beam is sent repeatedly at the S-SS/PSBCH block time domain resource position for calculating RSRP and/or SINR and used for receiving beam scanning by the receiving terminal. Since legacy UE can only see the position of S-SS/PSBCH block transmitting direct link synchronization information, the slot index indication manner of this embodiment is adopted, that is, the low N1 bit in the slot index indication of PSBCH is used to indicate the slot index of the first S-SS/PSBCH block time domain resource, and the high N2 bit is used to indicate the slot index of the fourth S-SS/PSBCH block time domain resource (as shown in fig. 7), where n1=log 2 (n_s-SS/PSBCH block) and n2=7-N1 can not affect the downlink synchronization and acquisition timing of legacy UE.
