Description

Technical Field

[0001] The embodiments of the present invention relate to the field of wireless technology, and in particular to a method, system, device and medium for determining uplink transmission resources. Background Art

[0002] In a dynamic time division duplexing (TDD) system, different base stations can be configured with different TDD frame structures. Therefore, at the same time, there will be base stations sending signals in downlink time slots / symbols and base stations receiving signals in uplink time slots / symbols in the network. The downlink transmission signal of the base station will cause strong interference to the uplink reception of other base stations. The base station that interferes with the uplink reception of other base stations is usually called a "disturbing base station". Correspondingly, the base station interfered by the downlink signal of other base stations is called a "disturbed base station". The interference between the two is inter-gNB cross-link interference (CLI).

[0003] Since the target user equipment (UE) cannot perform downlink reception and uplink transmission at the same time, it is necessary to reserve a certain time for uplink and downlink switching, and no transmission is performed during the switching time. During system transmission, the timing advance offset of the UE is configured through the n-Timing Advance Offset parameter, so that the timing of the UE uplink transmission has a certain timing advance (TA) relative to the base station, so as to achieve the purpose of reserving uplink and downlink switching time.

[0004] At present, in a dynamic TDD system, for the interfered base station, since it receives the uplink signal of the UE, it will also receive the CLI interference signal from the interfering base station. Please refer to Figure 1 , the uplink transmission of the target UE has a timing advance, so there is a timing misalignment problem between the uplink transmission from the target UE received by the interfered base station and the CLI from the interfering base station, and the timing difference between the two times exceeds the cyclic prefix (CP) length of the orthogonal frequency division multiplexing (OFDM) symbol.

[0005] The above timing misalignment problem makes it more difficult to suppress the interference of CLI between base stations. One way to solve the timing misalignment problem is to configure the timing advance of the UE to 0 through the n-Timing Advance Offset parameter in the serving cell system information SIB1, that is, N TA,offset=0, but this brings the problem that the uplink and downlink switching time of the TDD system may overlap or conflict with the time domain symbols of the UE's PUSCH / PUCCH transmission. Summary of the invention

[0006] The embodiments of the present invention provide a method, system, device and medium for determining uplink transmission resources to solve the problem of conflict between the uplink and downlink switching time of the existing TDD system and the time domain symbols of the PUSCH / PUCCH transmission of the UE.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] Please refer to Figure 2 , an embodiment of the present invention provides a method for determining uplink transmission resources, comprising:

[0058] Step 11: receiving a first signaling, wherein the first signaling includes: a first uplink time slot and a starting symbol position and a symbol length of a first symbol used for uplink transmission in the first uplink time slot, wherein the first uplink time slot is an uplink time slot for which an uplink and downlink switching time needs to be reserved;

[0059] Among them, the uplink time slot type includes an uplink time slot whose subsequent time slot is a downlink time slot, that is, the first uplink time slot in the embodiment of the present invention: an uplink time slot that needs to reserve uplink and downlink switching time, and other uplink time slots that do not need to reserve uplink and downlink switching time.

[0060] Step 12: Determine uplink transmission resources according to the first signaling.

[0061] The above-mentioned scheme of the embodiment of the present invention determines the uplink transmission resources by considering the uplink and downlink switching time, which can avoid the conflict between the uplink and downlink switching time and the time domain symbols transmitted by the UE, thereby avoiding the loss of data or control information during the transmission process, reducing the uplink data / control channel performance degradation caused by resource conflicts, and enhancing the stability of the transmission process.

[0062] Firstly, according to the subcarrier spacing of the TDD system, the number of OFDM symbols corresponding to the uplink and downlink switching time of the pre-configured TDD system is determined, which is recorded as n.

[0063] In the embodiment of the present invention, the switching time given in the protocol corresponding to FR1 can be adopted, that is, 25600Tc, which is approximately equal to 13us, where T c =1(Δf max ·N f ) is the basic time unit of the 5G NR frame structure, Δf max =480·10 3 , N f =4096. That is, in the embodiment of the present invention, the number of OFDM symbols corresponding to the uplink and downlink switching time of the TDD system, i.e., 13us, can be determined first according to the subcarrier spacing of the TDD system and the uplink and downlink switching time of the TDD system preconfigured by the protocol, and is recorded as n.

[0064] The embodiment of the present invention provides a method for determining uplink transmission resources when the first signaling is downlink control information (Downlink Control Information, DCI) signaling, specifically:

[0065] If the UE performs PUSCH transmission through dynamic grant (Dynamic Grant, DG) of the base station or configured grant (Configured Grant, CG) of Type 2, the base station sends DCI to indicate the time domain resources required for the UE to perform PUSCH transmission. The indicated time domain resources include the time slot offset (slotoffset) between the time slot where the PUSCH is actually transmitted and the time slot where the DCI signaling is located, and the starting symbol position S and symbol length L (SLIV or respectively indicate S and L) allocated to the PUSCH in the time slot determined by the slot offset.

[0066] In order to avoid the conflict between the time domain symbols of PUSCH transmission and the uplink and downlink switching time of the TDD system, the present invention provides an embodiment:

[0067] In the embodiment of the present invention, optionally, the first signaling is downlink control information DCI signaling, and the first symbol indicated in the DCI signaling does not include the last n symbols;

[0068] Determining the uplink transmission resource according to the first signaling includes:

[0069] According to the DCI signaling, a first symbol and a second symbol in the first uplink time slot are determined, wherein the first symbol is used for uplink transmission, and the second symbol is the last n symbols of the first uplink time slot and is used for uplink and downlink switching.

[0070] In an embodiment of the present invention, different time domain resource allocation lists (TDRA tables) can be configured for different uplink time slot types, or different rows in the same TDRA table can be configured, that is, the TDRA table configured for the first uplink time slot for which uplink and downlink switching time needs to be reserved or certain rows in the TDRA table, the first symbol indicated by which does not include the last n symbols.

[0071] When PUSCH transmission is scheduled or activated by DCI in the first uplink time slot, the DCI indicates a specified row in the time domain resource allocation list corresponding to the first uplink time slot or indicates a specified row in the time domain resource allocation list corresponding to the first uplink time slot, specifically:

[0072] In the embodiment of the present invention, optionally, the DCI signaling includes a designated row in a time domain resource allocation list corresponding to the first uplink time slot, and the first symbol indicated by the time domain resource allocation list corresponding to the first uplink time slot does not include the last n symbols in the first uplink time slot;

[0073] Alternatively, the DCI signaling includes a designated row in a time domain resource allocation list indicating the first uplink time slot, and the first symbol indicated by the designated row does not include the last n symbols in the first uplink time slot.

[0074] The embodiment of the present invention can make the included indication information more targeted and easy to configure by indicating the designated row in the time domain resource allocation list corresponding to the first uplink time slot and the designated row in the time domain resource allocation list corresponding to the first uplink time slot.

[0075] The embodiment of the present invention provides a method for determining uplink transmission resources when the first signaling is a radio resource control signaling (Radio Resource Control, RRC) signaling, specifically:

[0076] If the UE performs PUSCH transmission through Type 1 configured grant (Configured Grant, CG), the time domain resources required for the UE to perform PUSCH transmission are configured by RRC signaling. The configured time domain resources include the time slot offset of the PUSCH transmission time slot relative to the time slot indicated by the RRC parameter, and the starting symbol position and symbol length (SLIV or S and L respectively) allocated to the PUSCH in the time slot determined by the time slot offset.

[0077] In the embodiment of the present invention, optionally, the first signaling is a radio resource control RRC signaling, and the determining the uplink transmission resource according to the first signaling includes:

[0078] Determine, according to the RRC signaling, a first symbol and a second symbol in the first uplink time slot, wherein the first symbol is used for uplink transmission, and the second symbol is the last n symbols of the first uplink time slot, and is used for uplink and downlink switching;

[0079] Determine whether there is a time domain conflict between the first symbol and the second symbol, wherein n is the number n of the second symbols used for the uplink and downlink switching time;

[0080] If there is a time domain conflict, determine the number of symbols n of the conflicting part between the first symbol and the second symbol * , re-determine the first symbol in the first uplink time slot; according to the second symbol, the number of symbols n * and the re-determined first symbol to determine the uplink transmission resource.

[0081] First, it is necessary to determine whether there is a time domain symbol conflict.

[0082] The embodiment of the present invention provides a method for determining whether there is a time domain conflict between a first symbol and a second symbol, taking 14 OFDM symbols in a time slot as an example:

[0083] According to the starting symbol position S and symbol length L indicated by the TDRA table row, S+L is calculated. If S+L>14-n, it means that the last n symbols of the UE uplink transmission conflict with the uplink and downlink switching time of the TDD system, which will cause the transmission of these symbols to fail, causing the uplink data channel transmission performance of the TDD system to deteriorate. Figure 3 As shown, the last symbol of the target UE uplink transmission conflicts with the uplink and downlink switching time.

[0084] To avoid the above-mentioned conflict, an embodiment of the present invention provides a method for re-determining uplink transmission resources: determining the number of symbols n of the conflicting part between the first symbol and the second symbol * , re-determine the first symbol in the first uplink time slot; according to the second symbol, the number of symbols n* Re-determined first symbol.

[0085] There are mainly two embodiments, one is to remove the conflicting symbols from the resource elements (RE) allocated to PUSCH; the other is to calculate the required transport block size (TBS) first, and then remove some bits to avoid conflicts. Specifically:

[0086] In the embodiment of the present invention, optionally, the uplink transmission resource is a physical uplink shared channel PUSCH resource, and the re-determining the first symbol in the first uplink timeslot includes:

[0087] Re-determine the first symbol in the first uplink time slot according to the third symbol, wherein the third symbol is the first symbol minus n. * symbol after the conflicting symbol.

[0088] In the embodiment of the present invention, the conflicting symbols are directly removed, and the last n * symbols for rate matching, that is, the UE directly uses the last n symbols when calculating TBS. * symbols are removed from the RE resources allocated to PUSCH, such as Figure 4 , Figure 5 As shown, code block segmentation, channel coding and other operations are then performed. Specifically, the formula for calculating the number of REs that can be used for PUSCH transmission in a physical resource block (PRB) in the existing protocol is as follows: in, is the number of OFDM symbols that can be scheduled in a time slot; The number of OFDM symbols that can be scheduled in the previous time slot before removing the conflicting symbols.

[0089] The embodiment of the present invention provides a method for determining whether a first symbol and a second symbol have a time domain conflict. Taking 14 OFDM symbols in a time slot as an example: when S+L≥14, n * =n; when S+L<14, n * =n-[14-(S+L)], where n * is the number of conflicting symbols, and n is the number of symbols used for uplink and downlink switching.

[0090] In the embodiment of the present invention, optionally, the uplink transmission resource is a physical uplink shared channel PUSCH resource, and the re-determining the first symbol in the first uplink timeslot includes:

[0091] Determine, according to the first symbol, a transport block size TBS corresponding to the first symbol;

[0092] According to the transport block size TBS, at least a channel coding operation is performed on the transport block TB to obtain a coded transport block TB;

[0093] According to the * , puncture the encoded transport block TB so that the punctured TB does not occupy n of the conflicting part * symbols; wherein the puncturing includes at least one of the following: discarding some check bits or discarding bits corresponding to some symbols with conflicts;

[0094] The first symbol in the first uplink timeslot is re-determined according to the punctured TBS.

[0095] In the embodiment of the present invention, the UE first calculates the TBS according to the RE resources corresponding to the time domain symbol length configured by the RRC signaling, and performs operations such as code block segmentation and channel coding, and then punctures the encoded codeword according to the overlapping time domain symbols, discards some check bits, and adjusts the actual transmission code rate to adapt to the RE resources that can actually be used for PUSCH transmission. Of course, there may be operations such as interleaving, modulation, and resource mapping after channel coding.

[0096] The number n of OFDM symbols punctured or rate matched in the two embodiments is determined by the uplink and downlink switching time and subcarrier spacing of the TDD system. For example, when the subcarrier spacing of the TDD system is 30kHz and the uplink and downlink switching time of the TDD system is 13us, the number of OFDM symbols punctured / rate matched is 1.

[0097] The embodiment of the present invention further provides a method for determining an uplink transmission resource when the uplink transmission resource is a physical uplink control channel (PUCCH) resource. Specifically:

[0098] The existing protocol calculates the minimum number of PRBs required for PUCCH transmission in the frequency domain based on parameters such as the bit length of the uplink control information (UCI), the number of time domain symbols used for PUCCH transmission, the modulation order, and the maximum code rate of PUCCH coding. When the time domain symbols of PUCCH transmission conflict with the uplink and downlink switching time of the TDD system, the number of PRBs can be reduced accordingly. The corresponding number of time domain symbols, where The number of OFDM symbols allocated to PUCCH transmission in a time slot. In order to ensure that there are enough RE resources for PUCCH transmission, it is necessary to calculate according to the method in the protocol The minimum number of PRBs corresponding to the reduction.

[0099] In the embodiment of the present invention, optionally, the uplink transmission resource is a physical uplink control channel PUCCH resource, and the * and the re-determined first symbol, determining the uplink transmission resource comprises:

[0100] Re-determine the first symbol in the first uplink time slot according to the third symbol, wherein the third symbol is the first symbol minus n. * The symbol after the conflicting symbol;

[0101] Determining, according to the re-determined first symbol, a minimum number of physical resource blocks (PRBs) required in the frequency domain for transmission of the PUCCH;

[0102] According to the second symbol, the number of symbols n * and the re-determined first symbol and the number of PRBs to determine the uplink transmission resource.

[0103] In the embodiment of the present invention, optionally, the number n of the second symbols is determined according to the uplink and downlink switching time and the subcarrier spacing.

[0104] Further, in order to determine when the UE uses the method provided in the embodiment of the present invention to determine the transmission resources of the PUSCH / PUCCH, a high-level configuration corresponding to the above-mentioned process of determining the uplink transmission resources of the UE may be defined. If the terminal receives the high-level configuration or N TA,offset = 0, then the uplink transmission resources of the UE are determined according to the above method. If the terminal does not receive the corresponding high-level configuration and N TA,offset If it is not configured to 0, the uplink transmission resource of the UE is determined according to the existing protocol.

[0107] In an embodiment of the present invention, at the signaling end, a first signaling is sent to indicate the first uplink time slot and the starting symbol position and symbol length of the first symbol used for uplink transmission in the first uplink time slot, so as to avoid conflicts between the uplink and downlink switching time and the time domain symbols transmitted by the UE, thereby avoiding the loss of data or control information during the transmission process.

[0108] In an embodiment of the present invention, optionally, the first signaling is downlink control information DCI signaling, and the first symbol indicated in the DCI signaling does not include the last n symbols.
