Description

TECHNICAL FIELD

[0001] The present application relates to the field of wireless communication, in particular to a time domain resource determination method, device and medium. BACKGROUND

[0002] At present, 4G Long-Term Evolution (LTE) / Long-Term Evolution Advance (LTE-A) and 5G are facing more and more demands. From the current development trend, both 4G and 5G systems are researching to support enhanced mobile broadband, ultra-high reliability, ultra-low latency transmission, and massive connection features. In order to support the features of ultra-high reliability and ultra-low latency transmission, it is necessary to use shorter transmission time intervals to improve reliability in a repeated transmission manner. The shorter transmission time interval can be a single or several Orthogonal Frequency Division Multiplexing (OFDM) symbols. The Physical Downlink Control channel (PDCCH) is mainly used to carry scheduling information of downlink data transmission, scheduling information of uplink data transmission, inform time slot format and uplink power control, etc. And the more resources used to carry PDCCH, the higher the transmission reliability, wherein the resources are divided into frequency domain resources, i.e. resource blocks, and time domain resources, i.e. time domain symbols.

[0003] For some coverage-limited scenarios, if the frequency domain resources have been occupied in the maximum case, it is necessary to increase the time domain symbols to improve the coverage performance. However, in the scenario of coexistence of New Radio (NR) and LTE, in the existing mechanism, NR must be indicated by a continuous Control Resource Set (CORESET), which leads to the situation that NR and LTE time domain symbols conflict. According to the current NR protocol definition, if the PDCCH collides with the symbol where the LTE CRS is located, the PDCCH candidate is terminated, so only a small amount of time domain resources can be used to carry PDCCH, thereby reducing the reliability of PDCCH transmission.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0023] In one exemplary implementation Figure 1 This is a flowchart of a time-domain resource determination method provided in this application. This method is applicable to situations where the NR uses discontinuous time-domain symbols to carry the time-domain resources of the physical downlink control channel. This method can be executed by the base station provided in this application.

[0024] like Figure 1 As shown, the flowchart of the time-domain resource determination method provided in this application includes:

[0025] Step 101: Obtain the CORESET signaling parameters of the discontinuous control resource set in the new radio NR.

[0026] In one example, the CORESET signaling parameters for the discontinuous control resource set in the new radio NR are obtained, including:

[0027] determining time domain symbols of a long term evolution, LTE, frame structure occupied by a cell-specific reference signal, CRS, under an antenna port; generating a new radio, NR, CORESET signaling parameter according to the time domain symbols of the LTE frame structure occupied.

[0028] As shown in Figure 2 is a schematic diagram of LTE CRS, and no PDCCH can be transmitted on the symbols where LTE CRS is located, and Figure 2 It can be determined that the time domain symbols of the LTE frame structure occupied by 1 / 2 antenna port CRS are 0 / 4 / 7 / 11, the time domain symbols of the LTE frame structure occupied by 4 antenna port CRS are 0 / 1 / 4 / 7 / 8 / 11, and a NR CORESET signaling parameter is generated according to the time domain symbols of the LTE frame structure occupied.

[0029] In step 102, the non-continuous time domain symbols are determined according to the non-continuous CORESET signaling parameter and transmitted to the terminal.

[0030] The non-continuous time domain symbols are used as time domain resources carrying a physical downlink control channel, PDCCH.

[0031] In an example, the non-continuous CORESET signaling parameter includes a starting position of a monitoring occasion and non-continuous symbols.

[0032] In an example, determining the non-continuous time domain symbols according to the non-continuous CORESET signaling parameter includes: determining a position of a starting symbol of the non-continuous time domain symbols in a NR frame structure according to the starting position of the monitoring occasion; and determining a symbol position occupied by the non-continuous time domain symbols and a symbol length occupied in the NR frame structure according to the non-continuous symbols.

[0033] In an example, the non-continuous CORESET signaling parameter includes a starting position of a monitoring occasion, an occupied symbol value, and non-continuous symbols.

[0034] In an example, determining the non-continuous time domain symbols according to the non-continuous CORESET signaling parameter includes: determining a position of a starting symbol of the non-continuous time domain symbols in a NR frame structure according to the starting position of the monitoring occasion; determining a symbol length occupied by the non-continuous time domain symbols in the NR frame structure according to the occupied symbol value; and determining a symbol position occupied by the non-continuous time domain symbols in the NR frame structure according to the non-continuous symbols.

[0035] In one example, the non-contiguous CORESET signaling parameter includes: a non-contiguous symbol enabling parameter, a non-contiguous symbol determining parameter, and an occupied symbol value, wherein the non-contiguous symbol enabling parameter includes an enabling attribute or a non-enabling attribute.

[0036] In one example, determining the non-contiguous time domain symbol according to the non-contiguous CORESET signaling parameter includes: in a case where the non-contiguous symbol enabling parameter is the enabling attribute, the non-contiguous symbol determining parameter indicates a starting position of a monitoring occasion and a specific position of an occupied symbol; determining the starting symbol position of the non-contiguous time domain symbol and the occupied symbol position in the NR frame structure according to the non-contiguous symbol determining parameter; determining the occupied symbol length of the non-contiguous time domain symbol in the NR frame structure according to the occupied symbol value.

[0037] In one example, the non-contiguous CORESET signaling parameter includes: a symbol where the NR and the LTE CRS occupied symbols conflict, an offset value, an occupied symbol value, and a starting position of a monitoring occasion.

[0038] In one example, determining the non-contiguous time domain symbol according to the non-contiguous CORESET signaling parameter includes: determining the starting symbol position of the non-contiguous time domain symbol in the NR frame structure according to the starting position of the monitoring occasion; determining the occupied symbol length of the non-contiguous time domain symbol in the NR frame structure according to the occupied symbol value; determining the number of symbols of the non-contiguous time domain symbol that are offset backward in a case where the conflicting symbol is encountered according to the offset value.

[0039] In one example, the non-contiguous symbol includes: being indicated by a bit map or being indicated by a preset type.

[0040] In one example, the non-contiguous CORESET signaling parameter includes: a non-contiguous symbol enabling parameter, a non-contiguous symbol determining parameter, and an occupied symbol value, wherein the non-contiguous symbol enabling parameter includes an enabling attribute or a non-enabling attribute.

[0041] Case One:

[0042] When the non-contiguous CORESET signaling parameter includes: a starting position of a monitoring occasion and a non-contiguous symbol, the starting position of the monitoring occasion is represented by a symbol monitoringSymbolsWithinSlot, and the non-contiguous symbol is represented by a symbol duration.

[0043] Specifically, Figure 3The illustrated is a schematic diagram of LTE and NR frame structure taking 1 / 2 antenna port as an example, the discontinuous symbol duration can be indicated by a signaling BIT STRING (SIZE (14)), that is, indicated by a 14-bit bitmap, which can be set as 00110100000000, and the starting position of the monitoring occasion monitoringSymbolsWithinSlot can be set as 00100000000000, the starting position of the monitoring occasion indicates that the PDCCH starting symbol is 2, the discontinuous symbol indicates that the occupied symbol is 2 / 3 / 5, and the occupied symbol length is 3, thereby avoiding the symbol 4 which conflicts with LTE, and the determined discontinuous time domain symbol 2 / 3 / 5 is used as the time domain resource for carrying PDCCH.

[0044] wherein the discontinuous symbol is indicated by a 14-bit bitmap, and can also be indicated by a preset type. As shown in Tables 1 to 4, the discontinuous symbol preset type can be indicated, wherein any row in Tables 1 to 4 can be combined, and is not limited to 3-bit 8 states, for example, can be extended to 4-bit 16 symbol patterns, or 5-bit 32 symbol patterns.

[0053]

[0054]

[0055] The discontinuous symbol can be one of preset types of RRC (Radio Resource Control) configuration candidates. The preset type Pattern 1 can be represented by 3 bits 000, the preset type Pattern 2 can be represented by 3 bits 001, the preset type Pattern 3 can be represented by 3 bits 010, the preset type Pattern 4 can be represented by 3 bits 011, the preset type Pattern 5 can be represented by 3 bits 100, the preset type Pattern 6 can be represented by 3 bits 101, the preset type Pattern 7 can be represented by 3 bits 110, and the preset type Pattern 8 can be represented by 3 bits 111. When it is determined that the discontinuous symbol is Pattern 4 represented by 100 in Table 1, it is further determined that the discontinuous symbol substantially indicates 00110100000000, so that only 3 bits are used for representation, without occupying 14 bits. The discontinuous symbol is indicated in this way, so that signaling overhead can be saved, and processing speed can be improved.

[0056] It should be noted that the starting position symbol of the monitoring occasion has only one number 1, which indicates that the time domain resource of the NR frame structure is only used to carry one PDCCH. When the starting position symbol of the starting position of the monitoring occasion includes multiple numbers 1, it indicates that there are multiple monitoring occasions, and the time domain symbol of the NR frame structure can be used to carry multiple PDCCHs, as shown in the following table. Figure 4 The following table shows an example of 1 / 2 antenna ports, and the schematic diagram of the LTE and NR frame structure carrying multiple PDCCHs. The discontinuous symbol duration can be indicated by signaling BIT STRING (SIZE (14)) and set as 01110110100000, and the starting position of the monitoring occasion monitoringSymbolsWithinSlot can be set as 01000100000000. At this time, it indicates that the first PDCCH monitoring occasion in the search space Search Space occupies symbols 1 / 2 / 3, and the occupied symbol length is 3. The second PDCCH monitoring occasion occupies symbols 5 / 6 / 8, and the occupied symbol length is 3. The determined discontinuous time domain symbols 1 / 2 / 3 and 5 / 6 / 8 are used as time domain resources carrying PDCCHs.

[0057] It should be noted that the above embodiments are exemplified by taking the same symbol length occupied by two PDCCH monitoring occasions, and both are 3. Of course, for the case of including multiple monitoring occasions in the same search space Search Space, each PDCCH monitoring occasion can also occupy different symbol lengths. For example, the starting position of the monitoring occasion monitoringSymbolsWithinSlot can be set to 01000100000000, and the non-continuous symbol duration can be indicated by signaling BIT STRING(SIZE(14)) to be set to 01100110100000. At this time, it means that the first PDCCH monitoring occasion in the search space Search Space occupies 1 / 2 symbols, and the occupied symbol length is 2; the second PDCCH monitoring occasion occupies 5 / 6 / 8 symbols, and the occupied symbol length is 3, and the determined non-continuous time domain symbols 1 / 2 and 5 / 6 / 8 are respectively taken as the time domain resources carrying PDCCH.

[0058] It should be noted that the above are all exemplified by taking 1 / 2 antenna ports as an example. When the number of antenna ports is increased, such as Figure 5 The figure shown is an example of 4 antenna ports, and the schematic diagram of LTE and NR frame structure carrying multiple PDCCH. The non-continuous symbol duration can be indicated by signaling BIT STRING(SIZE(14)) to be set to 00110110011000, and the starting position of the monitoring occasion monitoringSymbolsWithinSlot can be set to 00100010000000. At this time, it means that the first PDCCH monitoring occasion in the search space Search Space occupies 2 / 3 / 5 symbols, and the occupied symbol length is 3; the second PDCCH monitoring occasion occupies 6 / 9 / 10 symbols, and the occupied symbol length is 3. And the determined non-continuous time domain symbols 2 / 3 / 5 and 6 / 9 / 10 are respectively taken as the time domain resources carrying PDCCH.

[0059] Case two:

[0060] When the non-continuous CORESET signaling parameters include: the starting position of the monitoring occasion, the occupied symbol value and the non-continuous symbol, the starting position of the monitoring occasion is represented by the symbol monitoringSymbolsWithinSlot, the occupied symbol value is represented by duration, and the non-continuous symbol is represented by location.

[0061] Specifically, Figure 3As shown is an example of 1 / 2 antenna port, a schematic diagram of LTE and NR frame structure, the discontinuous symbol location can be indicated by signaling BIT STRING(SIZE(14)), that is, indicated by a 14-bit bitmap, which can be set to 00110100000000, the occupied symbol value duration is set to 3, and the starting position of the monitoring occasion monitoringSymbolsWithinSlot can be set to 00100000000000. In combination with the above three parameter information, it can be determined that the discontinuous symbol occupies 2 / 3 / 5 symbols, thereby avoiding the symbol 4 which conflicts with LTE, and the determined discontinuous time domain symbol is used as 2 / 3 / 5 as a time domain resource carrying PDCCH. The difference from case one is that the discontinuous symbol is only used to indicate the symbol position occupied by the discontinuous time domain symbol, and does not indicate the occupied symbol length.

[0062] Among them, the above-mentioned discontinuous symbol is indicated by a 14-bit bitmap, and of course can also be indicated by a preset type. As shown in Table 1-Table 4 of the above-mentioned case one, the discontinuous symbol preset type, but at this time the information contained in the discontinuous symbol preset type shown in Table 1 is changed, that is, only used to indicate the symbol position occupied by the discontinuous time domain symbol, and does not indicate the occupied symbol length.

[0063] It should be noted that only one number 1 in the starting position symbol of the above-mentioned monitoring occasion indicates that only one time domain resource carrying PDCCH in the frame structure of NR. When the starting position symbol of the starting position of the monitoring occasion includes multiple numbers 1, it indicates that there are multiple monitoring occasions, and multiple PDCCH time domain symbols can be used in the NR structure to carry PDCCH, such as Figure 4 As shown is an example of 1 / 2 antenna port, a schematic diagram of LTE and NR frame structure carrying multiple PDCCH, the discontinuous symbol location can be indicated by signaling BIT STRING(SIZE(14)) and set to 01110110100000, the occupied symbol value duration is set to 3, and the starting position of the monitoring occasion monitoringSymbolsWithinSlot can be set to 01000100000000. At this time, it indicates that the first PDCCH monitoring occasion in the search space Search Space occupies 1 / 2 / 3 symbols, and the occupied symbol length is 3; the second PDCCH monitoring occasion occupies 5 / 6 / 8 symbols, and the occupied symbol length is 3. And the determined discontinuous time domain symbols 1 / 2 / 3 and 5 / 6 / 8 are used as time domain resources carrying PDCCH respectively.

[0064] It should be noted that when 4 antenna ports are used, the only difference between NR and LTE is the symbol position where the conflict occurs, and the way of determining the discontinuous time domain symbols is roughly the same as that of the 1 / 2 antenna port case, so the present embodiment will not be described again.

[0065] Case three:

[0066] When the discontinuous CORESET signaling parameter includes a discontinuous symbol enabling parameter, a discontinuous symbol determining parameter, and a symbol duration value, and the discontinuous symbol enabling parameter includes an enabling attribute or a non-enabling attribute, the discontinuous symbol enabling parameter is represented by the symbol discontinuous, the discontinuous symbol determining parameter is represented by the symbol monitoringSymbolsWithinSlot, and the symbol duration value is represented by the symbol duration.

[0067] Specifically, when the value of discontinuous is ENUMERATED{enabled}, it means that the discontinuous symbol enabling parameter is the enabling attribute, and in this case, the discontinuous symbol determining parameter monitoringSymbolsWithinSlot is not only used to indicate the starting position of the PDCCH monitoring occasion, but also used to indicate the specific position of the occupied symbol, to support the indication of the discontinuous time domain symbol. For example, as shown in Figure 4 the schematic diagram of the LTE and NR frame structure carrying multiple PDCCHs is shown, the discontinuous symbol determining parameter monitoringSymbolsWithinSlot can be set to 01110110100000, the symbol duration value duration is set to 3, and in combination with the above three parameters, it can be determined that the first PDCCH monitoring occasion in the search space Search Space occupies the symbols 1 / 2 / 3, and the length of the occupied symbols is 3; the second PDCCH monitoring occasion occupies the symbols 5 / 6 / 8, and the length of the occupied symbols is 3. And the determined discontinuous time domain symbols 1 / 2 / 3 and 5 / 6 / 8 are respectively used as the time domain resources carrying PDCCH.

[0068] It should be noted that in the case of determining the non-continuous symbol enabling parameter discontinuous contains the non-enabling attribute, the non-continuous symbol determination parameter monitoringSymbolsWithinSlot can only be used to indicate the starting position of the monitoring occasion, and cannot be used to indicate the specific position of the occupied symbol, and specifically the starting symbol position of the continuous time domain symbol in the NR frame structure is determined according to the non-continuous symbol determination parameter monitoringSymbolsWithinSlot; the symbol length occupied by the continuous time domain symbol in the NR frame structure is determined according to the occupied symbol value duration. Since the way of determining the continuous time domain symbol according to the above three parameters is not the focus of the present application, it will not be described again in this embodiment.

[0069] It should be noted that when 4 antenna ports are used, the symbol positions where NR and LTE conflict are different, and the way of determining non-continuous time domain symbols is basically the same as that of 1 / 2 antenna ports, so it will not be described again in this embodiment.

[0070] Case four:

[0071] When the non-continuous CORESET signaling parameter includes: the symbol where the NR and LTE CRS occupied symbols conflict, the offset value, the occupied symbol value and the starting position of the monitoring occasion, the symbol where the conflict occurs is represented by the symbol collidewithLTECRSsymbol, the offset value is represented by the symbol offsetOfcollidesymbol, the occupied symbol value is represented by duration, and the starting position of the monitoring occasion is represented by the symbol monitoringSymbolsWithinSlot.

[0072] Specifically, Figure 3The illustrated is a schematic diagram of the LTE and NR frame structure taking 1 / 2 antenna port as an example. The colliding symbol collidewithLTECRSsymbol can be indicated by signaling BIT STRING(SIZE(14)), that is, indicated by a 14-bit bitmap, which can be set as 00010000000000, indicating that the symbol 4 collides with the symbol occupied by the LTE CRS. The offset value offsetOfcollidesymbol can be indicated by signaling INTEGER(N), indicating that the offset value is set as N, and the maximum value of N is 13. In the embodiment, N can be set as 1, the occupied symbol value duration is set as 3, and the starting position of the monitoring occasion monitoringSymbolsWithinSlot is set as 00100000000000. Thus, according to the starting position of the monitoring occasion 00100000000000, the starting symbol position of the non-continuous time domain symbol in the NR frame structure is determined as symbol 2. According to the occupied symbol value duration, it is determined that the length of the symbol occupied by the non-continuous time domain symbol in the NR frame structure is 3, that is, the theoretical non-continuous time domain symbol should be 2 / 3 / 4 in the case of no collision. According to the colliding symbol collidewithLTECRSsymbol, it is determined that the symbol 4 collides with the LTE CRS, and needs to be offset backward and ensure the symbol length to be 3. According to the offset value offsetOfcollidesymbol, it is determined that the offset value is 1, that is, offset by one symbol from the colliding symbol position, and the newly supplemented symbol is determined as symbol 5, so as to determine the non-continuous time domain symbol as 2 / 3 / 5, and the determined non-continuous time domain symbol 2 / 3 / 5 is used as the time domain resource for carrying the PDCCH.

[0073] It should be noted that the above method can also adopt the default processing of offsetting 1 symbol backward, and the base station does not need to inform the offset value.

[0074] It should be noted that when 4 antenna ports are used, the NR and the LTE only differ in the colliding symbol position, and the way of determining the non-continuous time domain symbol is basically the same as that of the 1 / 2 antenna port. Therefore, the embodiment will not be described again.

[0075] The time domain resource determination method provided by the embodiment can obtain the non-continuous control resource set CORESET signaling parameter in the radio NR, determine the non-continuous time domain symbol according to the non-continuous control resource set CORESET signaling parameter, and transmit the non-continuous time domain symbol to the terminal, so as to realize that the NR can use the non-continuous symbol to carry the time domain resource of the physical downlink control channel in the case of coexistence of the NR and the LTE.

[0076] In one example implementation, Figure 6 is a flowchart of a time domain resource determination method provided by the present application. The method can be applied to the case where the NR adopts discontinuous time domain symbols to carry the physical downlink control channel. The method can be executed by the terminal provided by the present application.

[0077] In step 201, the discontinuous time domain symbols determined by the base station side according to the discontinuous control resource set CORESET signaling parameters are acquired.

[0078] In one specific implementation, if the base station side determines the discontinuous time domain symbols 2 / 3 / 5 according to the discontinuous CORESET signaling parameters, the terminal will acquire the discontinuous time domain symbols 2 / 3 / 5 determined by the base station side. The specific acquisition method can adopt a wireless transmission method. In the present embodiment, the type of the specific transmission method between the terminal side and the base station side is not limited. As long as the terminal side can acquire the discontinuous time domain symbols transmitted by the base station side, it is within the protection scope of the present application.

[0079] In step 202, the discontinuous time domain symbols are used as the time domain resources carrying the physical downlink control channel PDCCH.

[0080] Specifically, after the terminal side acquires the discontinuous time domain symbols 2 / 3 / 5 transmitted by the base station side, the terminal side will use the discontinuous time domain symbols determined in the NR frame structure as the time domain resources carrying the PDCCH, thereby solving the coverage problem of the PDCCH in the case of coexistence of the NR and the LTE.

[0081] In one example implementation, Figure 7 is a flowchart of a time domain resource determination method provided by the present application. The method can be applied to the case where the NR adopts discontinuous time domain symbols to carry the physical downlink control channel. The method can be executed by the terminal provided by the present application.

[0082] As shown in Figure 7 , the flowchart of the time domain resource determination method provided by the present application comprises:

[0083] In step 301, the starting position and the occupied symbol value of the monitoring occasion transmitted by the base station are acquired.

[0084] Specifically, in the default mode, the terminal can acquire the decision support system (DSS) mode or other coexistence scenarios with LTE, and the terminal can acquire the LTE antenna port information. In this case, the terminal can acquire the starting position of the monitoring occasion and the occupied symbol value sent by the base station, and the starting position of the monitoring occasion is represented by monitoringSymbolsWithinSlot, and the occupied symbol value is represented by duration.

[0085] Specifically, as shown in FIG. 1, the starting position of the monitoring occasion monitoringSymbolsWithinSlot can be set to 00100000000000, and the occupied symbol value duration can be set to 3. Figure 3

[0086] Step 302, when determining that the new radio (NR) and the long term evolution (LTE) cell-specific reference signal (CRS) have symbol collision, acquiring the collision symbol.

[0087] Specifically, in the embodiment, the terminal can acquire that it is currently in the DSS mode, and the number of the transmitting antenna port is 2, so as to determine that the symbol 4 collides with the LTE CRS, and the acquired symbol 4 is taken as the collision symbol.

[0088] Step 303, determining the discontinuous time domain symbol according to the starting position of the monitoring occasion, the occupied symbol value and the collision symbol.
