Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
the innovation points of the invention are as follows: firstly, the invention supports PSFCH feedback of invisible indication in different time slot periods; secondly, the invention supports services with different time delay requirements and corresponds to different feedback time delay requirements. The time interval between the psch transmission and the PSFCH carrying its HARQ feedback information (i.e. the feedback delay) may not be indicated in the SCI at least in the non-base-scheduled transmission Mode (Mode 2).
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
example 1:
Fig. 1(a) is a flowchart of an embodiment of a method for configuring feedback resources in the car networking, which can be used for a UE in the car networking, and specifically includes the following steps,
Step 101, receiving a transmission block, and acquiring a position of a corresponding resource block, where the transmission block corresponds to frequency domain position information of the resource block.
In step 101, the transport block is transmitted through the psch, receives the transport block, and obtains resource location information of the transport block and resource location information of a resource block corresponding to the transport block.
In step 101, the resource location information of the transport block includes frequency domain location information and time domain location information occupied by the transport block. The frequency domain position occupied by a transport block transmitted using the psch is contained in the frequency domain position of a resource block, which may be one or more carriers, or one or more BWPs, or one or more resource pools, or a portion of resources in one resource pool, in the frequency domain.
The resource position information of the resource block comprises frequency domain position information and time domain position information of the resource block. In the frequency domain, one or more transport blocks transmitted using the PSSCH may correspond to one resource block, where the one or more transport blocks transmitted using the PSSCH may be from the same or different Side Link (SL) communications.
In step 101, the frequency domain bandwidth occupied by the general resource block is greater than or equal to the frequency domain bandwidth occupied by the transport block, so that one or more transport blocks corresponding to one resource block occurs.
For example, the frequency domain position of the first transmission block occupies 1-2 PRB, the frequency domain position of the second transmission block occupies 3-4 PRB, the frequency domain position of the third transmission block occupies 11-12 PRB, the frequency domain position of the first resource block occupies 1-10 PRB, the frequency domain position of the second resource block occupies 11-20 PRB, and then the first transmission block and the second transmission block correspond to the first resource block, and the third transmission block corresponds to the second resource block.
And step 102, indexing the feedback resources in the configuration information through the frequency domain position indication information, and determining the resource configuration of the feedback channel corresponding to the transmission block according to format information, frequency domain position information and time domain position information in the feedback resource configuration information.
it should be noted that, unless otherwise specified, the feedback channel mentioned in this document refers to a feedback channel corresponding to the transport block.
It should be further noted that the resource block corresponding to the transport block is also written as a transport resource block or a PSSCH transport resource block in this application document, and the feedback resource configuration information is also written as a feedback resource, a PSFCH resource, or a PSFCH resource configuration information in this application document.
it should be further noted that the frequency domain position indication information is used to indicate the frequency domain position of the resource block, and the frequency domain position indication information of the resource block in this application document is the frequency domain position indication information.
In step 102, mapping to the feedback resource configuration information through the resource block, rather than directly mapping to the feedback resource configuration information through the transport block, is because one resource block may correspond to 1 or more transport blocks, which reduces overhead compared to directly mapping to the feedback resource configuration information through the transport block.
In step 102, one transport block corresponds to one feedback channel. The configuration information includes one or more PSFCH resource sets (resource sets), each PSFCH resource set includes one or more PSFCH resources, one PSFCH resource corresponds to one kind of PSFCH resource configuration information, and one kind of PSFCH resource configuration information corresponds to one kind of PSFCH format. The resource allocation of the feedback channel comprises format information of the feedback channel, time domain position information of the feedback channel, and frequency domain position information of the feedback channel, and corresponds to a kind of PSFCH resource allocation information, and the resource allocation of the feedback channel is determined by the PSFCH resource allocation information. The receiving UE will further generate a feedback channel using the resource configuration of the feedback channel.
In step 102, the configuration information includes frequency domain position indication information, which is used to indicate a frequency domain position of the resource block, and is further used to index feedback resource configuration information in the configuration information, the feedback resource in the configuration information is indexed by the frequency domain position indication information of the resource block, and a mapping relationship between the frequency domain position indication information of the resource block and the feedback resource is included in the configuration information or the resource configuration information of the feedback resource.
The fact that the mapping relationship between the frequency domain position indication information of the resource block and the feedback resource is included in the resource configuration information of the feedback resource means that the configuration information of a PSFCH resource at least includes the following information: the method includes the steps of obtaining resource configuration information of feedback resources corresponding to a transmission block through frequency domain position indication information of a resource block corresponding to a corresponding PSSCH transmission block.
The fact that the mapping relationship between the frequency domain position indication information of the resource block and the feedback resource is contained in the configuration information means that the configuration information of one PSFCH resource at least contains PSFCH format information, PSFCH time domain position information and PSFCH frequency domain position information, the configuration information contains the mapping relationship between the corresponding PSSCH transmission resource block and the PSFCH resource configuration, and the resource configuration information of the feedback resource corresponding to the transmission block is obtained through the mapping relationship.
Fig. 1(b) shows a resource block, a feedback resource and a mapping relationship in an embodiment of a feedback resource configuration in the internet of vehicles, which specifically includes:
In the mapping relation between the resource blocks and the feedback resources, M resource blocks and N feedback resources exist, and the frequency domain position information of the feedback resources is indexed through the frequency domain position indication information of the resource blocks. The mapping relationship between the resource block and the feedback resource may be one-to-one, or one-to-many, that is, one resource block corresponds to one or more PSFCH resources.
It should be noted that the configuration of a PSFCH resource may also include other information to support the generation of the resource configuration of the feedback channel.
In step 102, the manner of acquiring the configuration information may be a higher layer signaling and/or a physical layer signaling, which is notified by the network device or the sending UE of SL; or by means of device writing. The device writing indicates that the device sets the relevant configuration parameters according to the protocol convention, and the relevant configuration information is not required to be acquired in an air interface mode.
Further, the configuration information may be one or more information joint indications, for example, the configuration information sends PSFCH resource set information through a high-layer signaling, and then indicates, through a physical layer signaling, which specific PSFCH resource in the PSFCH resource set is adopted by the terminal, where the PSFCH resource indicated by the physical layer signaling needs to conform to a mapping relationship between a resource block for PSSCH transmission and the PSFCH resource.
in step 102, format information in the resource configuration of the feedback channel is determined according to format information in the resource configuration information of the feedback resource.
Specifically, the transport block corresponds to the resource block, and the resource block corresponds to configuration information of a PSFCH resource, where the configuration information of the PSFCH resource includes PSFCH format information as the feedback channel format information.
Preferably, the format information of one feedback resource is one of PUCCH format 0 to format 4, and thus, the format information of the feedback channel is one of PUCCH format 0 to format 4. It should be noted that the format information of the feedback channel is in a PSFCH format and is used to generate the feedback channel, and the format information may be the same as PUCCH format 0, format 1, format 2, format 3, or format 4, or may be in another format, which is not limited herein.
If the PSFCH format corresponding to the feedback channel is the same as the PUCCH format 0, the information such as initial cyclic offset of the feedback channel, the continuous symbol length of the feedback channel and the like is further indicated; if the PSFCH format corresponding to the feedback channel is the same as the PUCCH format 1, the information such as initial cyclic shift of the feedback channel, the continuous symbol length of the feedback channel, the time domain orthogonal spread spectrum code index and the like is further indicated; if the PSFCH format corresponding to the feedback channel is the same as the PUCCH format 2, further indicating the information such as the continuous symbol length of the feedback channel, the number of PRBs occupied by the frequency domain of the feedback channel and the like; if the PSFCH format corresponding to the feedback channel is the same as the PUCCH format 3, further indicating the information such as the continuous symbol length of the feedback channel, the number of PRBs occupied by the frequency domain of the feedback channel and the like; and if the PSFCH format corresponding to the feedback channel is the same as the PUCCH format 4, further indicating the information such as the continuous symbol length of the feedback channel, the number of PRBs occupied by the frequency domain of the feedback channel, the length of the orthogonal spreading code, the index of the orthogonal spreading code and the like.
In step 102, frequency domain position information in the resource configuration of the feedback channel is determined according to the frequency domain position information in the resource configuration information of the feedback resource.
Specifically, the transport block corresponds to the resource block, the resource block corresponds to configuration information of a PSFCH resource, the configuration information of the PSFCH resource includes frequency domain position information, and the frequency domain position information of the feedback channel is indicated by the frequency domain position information.
In embodiment 1 of the present invention, the frequency domain location information of the feedback resource at least includes one of: the frequency domain starting PRB position and the frequency domain occupy the number of PRBs.
Optionally, the number of PRBs occupied by the PSFCH frequency domain in the PSFCH resource configuration information may be indicated by the PSFCH format information in the PSFCH resource configuration information.
Optionally, the starting location of the PSFCH frequency domain PRB in the PSFCH resource configuration information may be indicated by the frequency domain location indication information of the resource block corresponding to the PSFCH resource configuration. For example, the frequency-domain starting PRB position of the psch transmission resource block is the same as the frequency-domain starting PRB position of the PSFCH in the corresponding PSFCH resource configuration information, or there is a certain estimation relationship between the frequency-domain starting PRB position of the psch transmission resource block and the frequency-domain starting PRB position of the PSFCH in the corresponding PSFCH resource configuration information, for example, if the frequency-domain starting PRB position of the psch transmission resource block plus an offset is the frequency-domain starting PRB position of the PSFCH in the corresponding PSFCH resource configuration information, the frequency-domain starting PRB position of the PSFCH resource block may be obtained by using the frequency-domain position of the psch resource block.
In step 102, the relationship between the feedback resource configuration information and the feedback channel is: the resource allocation of the feedback channel is indicated by the feedback resource allocation information, that is, the resource allocation of the feedback channel is the same as the feedback resource allocation information, or has a corresponding relationship with the feedback resource allocation information.
The frequency domain position information of the feedback channel comprises the number of PRBs occupied by the frequency domain of the feedback channel and/or the frequency domain starting PRB position of the feedback channel.
optionally, the frequency domain occupied PRB number information of the feedback channel may be indicated by feedback channel format information in a corresponding feedback channel resource configuration, where the information is the same as the PSFCH format information in the PSFCH resource configuration information corresponding to the feedback channel resource configuration.
Optionally, the frequency-domain starting PRB position of the feedback channel may be the same as the PSFCH frequency-domain starting PRB position in the PSFCH resource configuration information corresponding to the feedback channel resource configuration, or the same as the PSSCH frequency-domain starting PRB position corresponding to the transmission block, or the same as the PSCCH frequency-domain starting PRB position corresponding to the transmission block, or the same as the position obtained by superimposing an offset on the frequency-domain starting PRB position of the feedback channel.
Optionally, the frequency-domain starting PRB position of the feedback channel is the same as the position of the feedback resource after the offset is superimposed on the frequency-domain starting PRB position, which means that the frequency-domain starting PRB position of the feedback channel is determined by combining the PSFCH frequency-domain starting PRB position in the corresponding PSFCH resource configuration information with the first indication information. The first indication information comprises frequency domain position information and/or time domain position information occupied by the transmission block, and/or frequency domain position information and/or time domain position information of PSCCH corresponding to the transmission block, and/or distinguishing receiving UE related ID information, and/or distinguishing sending UE related ID information.
for example, the PSFCH resource frequency domain starting PRB position is provided in the PSFCH resource configuration information, and the feedback channel frequency domain PRB starting position is obtained by superimposing an offset related to the time domain position occupied by the transport block on the corresponding PSFCH resource frequency domain starting PRB position in the PSFCH resource configuration information. For another example, the PSFCH resource frequency domain starting PRB position is provided in the PSFCH resource configuration information, and the feedback channel frequency domain PRB starting position is obtained by superimposing an offset related to the ID for distinguishing the receiving UE on the corresponding PSFCH resource frequency domain starting PRB position in the PSFCH resource configuration information.
In step 102, time domain position information in the resource configuration of the feedback channel is determined according to the time domain position information in the resource configuration information of the feedback resource.
specifically, the transport block corresponds to the resource block, the resource block corresponds to configuration information of a PSFCH resource, the configuration information of the PSFCH resource includes time domain position information, and the time domain position information of the feedback channel is indicated by the time domain position information.
the time domain position information of the feedback resource at least comprises one of the following information: the occupied slot index, the slot starting symbol position and the continuous symbol length, that is, the PSFCH time domain position information in the PSFCH resource configuration information includes the slot index occupied by the PSFCH time domain, and/or the starting symbol position in the PSFCH slot, and/or the PSFCH continuous symbol length.
Alternatively, the PSFCH persistent symbol length in one kind of PSFCH resource configuration information may be indicated by the PSFCH format information in the PSFCH resource configuration information.
Optionally, the starting symbol position in the PSFCH slot in one of the PSFCH resource configuration information may also be indicated by default. For example, if the PSFCH format corresponding to the PSFCH resource lasts for a symbol length of N in the time domain (N is an integer greater than equal to 1), the nth last symbol in the slot is corresponding to the PSFCH starting symbol position.
Optionally, a slot index occupied by the PSFCH time domain in the PSFCH resource configuration information corresponds to a PSFCH feedback period for supporting the transport block, and may further correspond to a PSFCH feedback period. The method for determining the time slot index occupied by the PSFCH time domain in the PSFCH resource configuration information includes at least one of the following two ways:
The first way is that the occupied time slot index of the feedback resource is determined by the feedback cycle and the time slot offset of the feedback resource:
Wherein m is the occupied time slot index, μ is the subcarrier spacing configuration of the feedback channel, and is the time slot number contained in one frame, nf is the frame number, P is the feedback period of the feedback resource, and Y is the time slot offset.
for example, assuming that the PSFCH feedback period is 4 slots, the offset of the PSFCH slot is 1 slot, and the number of slots included in 1 system frame is 10, under a subcarrier spacing configuration, the slot index m occupied by the PSFCH time domain is {1,5,9} under a system frame of 0, and the slot index m occupied by the PSFCH time domain is {3,7} under a system frame of 1.
it should be noted that, the PSFCH feedback period and/or the PSFCH timeslot offset may be indicated in the configuration information, that is, different PSFCH resources utilize the same PSFCH feedback period and/or different PSFCH resources utilize the same PSFCH timeslot offset; or the PSFCH feedback period and/or the PSFCH timeslot offset are indicated in the PSFCH resource configuration information, that is, one PSFCH resource configuration information corresponds to one PSFCH feedback period, and/or one PSFCH resource configuration information corresponds to one PSFCH timeslot offset, and the PSFCH feedback periods corresponding to different PSFCH resources may be the same or different, and the PSFCH timeslot offsets corresponding to different PSFCH resources may be the same or different.
The PSFCH feedback period may further use PSFCH format information in the PSFCH resource configuration information to implicitly indicate a time slot index occupied by the PSFCH time domain, that is, one PSFCH format corresponds to one PSFCH feedback period.
For example, the PSFCH format information corresponds to HARQ feedback information carrying 1bit, and then the feedback period of the PSFCH is 1 timeslot, that is, the PSFCH timeslot index includes each timeslot available for SL transmission in 1 frame, and 1 PSFCH corresponds to PSSCH transmission feedback of 1 timeslot. For another example, the PSFCH format information corresponds to HARQ feedback information carrying 2 bits, and the PSFCH feedback cycle is 2 slots, that is, the PSFCH slot index is the 2 nd slot in each 2 slots, and 1 PSFCH corresponds to the PSSCH transmission feedback of 2 slots. For another example, if the PSFCH format information corresponds to HARQ feedback information carrying more than 2 bits, the PSFCH feedback period is M slots, where M is an integer greater than 2, that is, the PSFCH slot index is the mth slot in each M slots, and 1 PSFCH corresponds to the PSSCH transmission feedback of M slots.
The second way is that the occupied time slot index of the feedback resource is included in the resource configuration information and/or the configuration information of the feedback resource, that is, the time slot index occupied by the PSFCH time domain in one frame is indicated in the PSFCH resource configuration information or the configuration information.
figure 1(c) shows an occupied time slot index determination method of an embodiment of the feedback resource configuration of the internet of vehicles,
Specifically, the slot index indicating the PSFCH time domain occupancy in a frame in the configuration information or the configuration information of the PSFCH resource may be a slot index value given the PSFCH time domain occupancy in a frame.

The candidate time slot index configuration index occupied by the PSFCH time domain and the corresponding time slot index occupied by the PSFCH time domain are given in the configuration information.
In table 1 above, the slot index configuration index occupied by the PSFCH time domain includes 3 configuration modes, and in mode 1, the slot index occupied by the PSFCH time domain is {0,1,2,3,4,5,6,7,8,9}, that is, each slot performs HARQ feedback, and the slot offset is 0; in the mode2, the time slot index occupied by the PSFCH time domain is {0,2,4,6,8}, that is, HARQ feedback is performed every 2 time slots, and the time slot offset is 0; in the mode 3, the slot index occupied by the PSFCH time domain is {0,4,8}, that is, HARQ feedback is performed every 4 slots, and the slot offset is 0.

Optionally, the starting symbol position of the time slot is the same as the starting symbol position of the time slot of the feedback resource, or the position of the time slot after the offset is superimposed on the starting symbol position of the time slot of the feedback resource, that is, the starting symbol position in the feedback channel time slot in the feedback channel resource configuration is the same as the starting symbol position in the PSFCH resource configuration information corresponding to the feedback channel resource configuration, or the starting symbol position in the PSFCH time slot in the corresponding PSFCH resource configuration information is determined by combining the first indication information with the starting symbol position. The first indication information comprises frequency domain position information and/or time domain position information occupied by a transmission block, and/or frequency domain position information and/or time domain position information of a PSCCH corresponding to the transmission block, and/or distinguishing receiving UE related ID information, and/or distinguishing sending UE related ID information.
For example, a starting symbol position in the PSFCH slot is provided in the PSFCH resource configuration information, and the starting symbol position in the feedback channel slot is a position corresponding to the PSFCH slot starting symbol in the PSFCH resource configuration information, and an offset related to a time domain position occupied by the first transport block is superimposed on the starting symbol position. For another example, the starting symbol position in the PSFCH slot is provided in the PSFCH resource configuration information, and the starting symbol position in the first feedback channel slot is superposed with an offset related to the ID for distinguishing the receiving UE, for the corresponding PSFCH slot starting symbol position in the PSFCH resource configuration information.

For example, when the feedback channel feedback period is the same as the PSFCH feedback period in the PSFCH resource configuration information corresponding to the feedback channel resource configuration, the feedback channel timeslot offset is related to the PSFCH timeslot offset and/or the first indication information in the PSFCH resource configuration information corresponding to the feedback channel resource configuration. Further, according to formula 1, a slot index occupied by a feedback channel time domain is determined through a feedback period of the feedback channel and a slot offset.
in step 102, the UE does not want to determine that the symbol where the feedback channel is located is determined according to the configuration information and the frame structure common configuration of the uplink and downlink and the side link, and is used for uplink, downlink, or collision of PSCCH and PSCCH transmission symbols occurs.
