Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a resource determination method and device. Background Art

[0002] The main difference between a network controlled repeater (NCR) and a traditional relay is that the base station can perform network control on the NCR serving it. There are two links between the base station and the NCR, one is the control link and the other is the backhaul link. There is one link between the NCR and the UE, which is the access link.

[0003] The related technology supports beamforming of Access link to improve the receiving performance on the terminal side, wherein the beam indication information of Access link includes: beam index, time domain information, reference SCS, etc. Since the beam indication information of Access link configured by the base station to NCR does not include the CP type, when NCR determines the time domain information corresponding to the configured beam, it cannot determine the specific position and length of the corresponding configuration symbol, thereby reducing the communication quality.

[0133] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0134] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0135] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems, especially 5G systems. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, etc. These various systems include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0136] First, the following contents are introduced:

[0137] Figure 1 It is a schematic diagram of the structure of the NCR link provided in the related art, such as Figure 1 As shown in the figure, the main difference between the network controlled repeater NCR and the traditional relay is that the base station can perform network control on the NCR serving it. The figure below shows the link relationship between the base station, NCR and the terminal. There are two links between the base station and NCR, one is the control link (Control link) and the other is the backhaul link (Backhaul link). There is one link between the NCR and the UE, which is the access link (Access link).

[0138] In the communication system of the related art, the beam forming of the Access link is supported to improve the receiving performance on the terminal side, wherein the beam indication information of the Access link includes: beam index, time domain information, reference SCS, etc.

[0139] Three types of Access link beam indication information supported in the related art include: periodic indication information, semi-persistent indication information and non-periodic indication information.

[0140] Among them, the beam indication information of the Access link with periodic and semi-continuous indication includes: beamindex, time resource (time domain information, including {Starting slot defined as the slot offset, starting symbol defined by symbol offset within the slot, duration defined by the number of symbols}), reference SCS, periodicity, priority flag, etc.

[0141] The beam indication information of the non-periodic Access link includes: beamindex (beam index), timeresource (time domain information, including {Starting slot defined as the slot offset, starting symbol defined by symbol offset within the slot, durationdefined by the number of symbols}), and reference SCS (reference SCS).

[0142] When different types of indication information indicate different beam directions at the same time, that is, when conflicts occur, the following principles should be followed:

[0143] When the priority flag is not configured: Aperiodic beam indication > semi-persistent beam indication > periodic beam indication Aperiodic beam indication > semi-persistent beam indication > periodic beam indication.

[0144] When the priority flag is configured: semi-persistent beam indication and periodic beam indication have higher priority than aperiodic beam indication, and periodic beam indication has higher priority than aperiodic beam indication.

[0145] Since the beam indication information of the Access link configured by the base station to the NCR does not include the CP type, the NCR cannot determine the specific position and length of the corresponding configuration symbol when determining the time domain information corresponding to the configured beam. Therefore, there are two problems that need to be solved:

[0146] (1) How to determine the CP type in the beam indication information (determine whether it is a normal cyclic prefix (NCP) or an extended cyclic prefix (ECP));

[0147] (2) Figure 2 It is a schematic diagram of the length of each CP type provided by the related art, such as Figure 2 As shown in FIG. 1 , only the position boundaries of integer multiples of 0.5 ms are aligned under different CP types. When different beam indication information overlaps in time domain and the CP types are different, how should the beam switching position be determined?

[0148] The embodiments of the present application provide a resource determination method and device to improve communication quality.

[0149] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0150] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0151] Figure 3 is one of the flow charts of the resource determination method provided in the embodiment of the present application, such as Figure 3 As shown, the method is applied to a repeater NCR, and the method comprises the following steps:

[0152] Step 300: Obtain beam indication information, where the beam indication information is used to indicate beam-related information of an access link of the NCR, where the beam-related information includes time domain resources;

[0153] Specifically, to improve the reception performance on the terminal side, the base station can send beam indication information to the NCR to indicate the beamforming transmission resources of the Access link;

[0154] Step 310, determining the CP type of the symbol of the time domain resource;

[0155] Specifically, in order to determine the symbol length of the time domain resource and the beam index on the time domain resource, it is necessary to first determine the CP type of the symbol of the time domain resource corresponding to the beam indicated by the beam indication information.

[0156] Step 320: Determine the symbol length of the time domain resource and the beam index on the time domain resource based on the beam indication information and / or the CP type of the symbol.

[0157] Specifically, after obtaining the beam indication information and the CP type, the symbol length of the time domain resource and the beam index on the time domain resource can be further determined to perform beam shaping.

[0158] The embodiment of the present application designs a solution for determining the CP type of the Access link beam indication information of the NCR and the situation when the beam indication information overlaps in time domain and the CP types are different. It is used to determine the CP type in the beam indication information and how to determine the beam switching position when the beam indication information of different CP types overlaps in time domain, clarifies the transmission resources of the Accesslink beam, and improves the communication quality.

[0159] The resource determination method provided in the embodiment of the present application first determines the CP type of the symbol of the time domain resource corresponding to the beam indicated by the beam indication information, and determines the symbol length of the time domain resource and the beam index on the time domain resource based on the beam indication information and / or the CP type of the symbol, thereby clarifying the transmission resources of the beam of the Access link and improving the communication quality.

[0160] Optionally, in some embodiments, the beam indication information is specifically used to indicate one or more of the following:

[0161] Beam index, time domain resources, reference subcarrier spacing, CP type.

[0162] Specifically, different types of Access link beam indications can include the following information:

[0163] (1) beam index;

[0164] (2) Time domain resources, including starting time slot, starting symbol, and duration;

[0165] Optionally, the starting time slot may be configured by a time slot offset within a cycle;

[0166] Optionally, the start symbol may be configured by a symbol offset within a time slot;

[0167] Optionally, the duration may be configurable by the number of symbols;

[0168] (3) referencing the SCS to determine the OFDM symbol length, where the OFDM symbol length does not include CP length information;

[0169] Specifically, the CP length information needs to be determined according to the CP type.

[0170] Therefore, the CP type can also be determined by explicit or implicit indication of beam indication information.

[0171] Optionally, in some embodiments, the beam indication information includes CP type indication information;

[0172] The determining the CP type of the symbol of the time domain resource includes:

[0173] Based on the CP type indication information, determine the CP type of the symbol of the time domain resource.

[0174] Specifically, the CP type can be explicitly indicated through beam indication information;

[0175] For example, it can be consistent with the SCS configuration method on each time resource;

[0176] For example, the CP type may be indicated by a CP type indication information;

[0177] For example, periodic, semi-static, and non-periodic beam indication information are configured with their respective CP types through RRC signaling.

[0178] In some embodiments, the method of explicitly indicating the CP type is implemented as follows:

[0179]

[0180]

[0181]

[0182] Some restrictions can be added during base station configuration:

[0183] For example, the referenceCP-r18 configuration types of different PeriodicFwdResourceSets are the same, that is, they are all extended CP or NCP.

[0184] Optionally, in some embodiments, the determining the CP type of the symbol of the time domain resource includes:

[0185] When the value of the reference subcarrier spacing is a first preset value, determining a CP type of a symbol of the time domain resource based on the beam indication information;

[0186] or

[0187] Based on a default CP type, a CP type of a symbol of the time domain resource is determined.

[0188] Specifically, the first preset value may be SCS=60 KHz, or other reference subcarrier spacing applicable to ECP, which is not limited in the embodiments of the present application.

[0189] Specifically, a default CP type can be predefined, and NCP can be confirmed as the default CP type. The base station configures the CP type only when ECP needs to be used;

[0190] Specifically, a default CP type can be predefined, and ECP can be confirmed as the default CP type. The base station configures the CP type only when NCP needs to be used;

[0191] For example, taking the default CP type as NCP, the CP type of the symbol of the time domain resource is configured, such as NCP or ECP, only when the reference SCS indicated by the beam indication information is SCS=60KHz; otherwise, the default CP type is NCP.

[0192] For example, taking the default CP type as NCP, after the NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS = 60KHz, the CP type of the symbol of the time domain resource is determined to be NCP or ECP based on the beam indication information; otherwise, the default CP type is NCP, wherein the beam indication information can indicate the CP type implicitly or explicitly, which will not be repeated here.

[0193] For example, taking the default CP type as NCP, after the NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS=60KHz (ECP), the CP type of the symbol of the time domain resource is determined to be ECP based on the beam indication information; otherwise, the default CP type is NCP.

[0194] For example, taking the default CP type as NCP, after NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS = 60KHz (ECP), the CP type of the symbol of the time domain resource is determined based on the CP type indication information in the beam indication information; otherwise, the default CP type is NCP.

[0195] In some embodiments, the method of explicitly indicating the CP type is implemented as follows:

[0196]

[0197]

[0198]

[0199]

[0200]

[0201] Optionally, in some embodiments, the determining the CP type of the symbol of the time domain resource includes:

[0202] In a case where the beam indication information includes CP type indication information, determining the CP type of the symbol of the time domain resource based on the CP type indication information;

[0203] or

[0204] Based on a default CP type, a CP type of a symbol of the time domain resource is determined.

[0205] Specifically, a default CP type can be predefined, and NCP can be confirmed as the default CP type. The base station configures the CP type only when ECP needs to be used;

[0206] Specifically, a default CP type can be predefined, and ECP can be confirmed as the default CP type. The base station configures the CP type only when NCP needs to be used;

[0207] For example, taking the default CP type as NCP, a CP type indication information is configured only when the reference SCS indicated by the beam indication information is SCS=60KHz, to indicate that the CP type of the symbol of the time domain resource is NCP or ECP; otherwise the default CP type is NCP.

[0208] For example, taking the default CP type as NCP as an example, a CP type indication information is configured only when ECP needs to be used, to indicate that the CP type of the symbol of the time domain resource is NCP or ECP; otherwise, the default CP type is NCP.

[0209] For example, taking the default CP type as NCP, after the NCR receives the beam indication information, when the beam indication information includes CP type indication information, the CP type of the symbol of the time domain resource is determined to be NCP or ECP based on the beam indication information; otherwise, the default CP type is NCP.

[0210] Optionally, in some embodiments, the default CP type is NCP.

[0211] Optionally, in some embodiments, the determining the CP type of the symbol of the time domain resource includes:

[0212] When the reference subcarrier spacing is a second preset value, determining that the CP type of the symbol of the time domain resource is NCP; or,

[0213] When the value of the reference subcarrier spacing is a third preset value, it is determined that the CP type of the symbol of the time domain resource is ECP.

[0214] Specifically, compared with the related technology, an SCS configuration value can be added: a third preset value; when the base station needs to use ECP, the third preset value can be indicated in the beam indication information; after receiving the beam indication information, the NCR determines that the SCS indicated in the beam indication information is the third preset value, and then the CP type of the symbol of the time domain resource can be determined to be ECP. After receiving the beam indication information, the NCR determines that the SCS indicated in the beam indication information is other configuration values ​​(i.e., the second preset value), and then the CP type of the symbol of the time domain resource can be determined to be NCP.

[0215] Specifically, the third preset value may be SCS=60KHz (ECP), or other reference subcarrier spacing applicable to ECP, which is not limited in the embodiment of the present application.

[0216] Specifically, the second preset value may be a configuration value of other reference subcarrier spacing except the third preset value, which is not limited in the embodiment of the present application.

[0217] For example, compared with the related technology, an SCS configuration value can be added: SCS=60kHz (ECP) as the third preset value; when the base station needs to use ECP, it can indicate SCS=60KHz (ECP) in the beam indication information; after receiving the beam indication information, the NCR determines that the SCS indicated in the beam indication information is 60KHz (ECP), and then it can be determined that the CP type of the symbol of the time domain resource is ECP. After receiving the beam indication information, the NCR determines that the SCS indicated in the beam indication information is other configuration values, and then it can be determined that the CP type of the symbol of the time domain resource is NCP.

[0218] In some embodiments, the method of explicitly indicating the CP type is implemented as follows:

[0219]

[0220]

[0221]

[0222]

[0223]

[0224] Optionally, in some embodiments, the third preset value is used to indicate that the reference subcarrier spacing and the CP type are ECP;

[0225] Optionally, the third preset value includes 60KHzECP.

[0226] Optionally, the third preset value is a reference subcarrier spacing associated with the ECP.

[0227] Specifically, the third preset value is different from the second preset value, that is, the second preset value may be a configuration value of other reference subcarrier spacings except 60 KHz ECP.

[0228] Specifically, the third preset value is different from the second preset value, that is, the second preset value may be a configuration value of other reference subcarrier spacings except the reference subcarrier spacing associated with the ECP.

[0229] Optionally, in some embodiments, the determining the CP type of the symbol of the time domain resource includes:

[0230] When the value of the beam index belongs to the first value range, determining that the CP type of the symbol of the time domain resource is NCP; or,

[0231] When the value of the beam index belongs to the second value range, it is determined that the CP type of the symbol of the time domain resource is ECP.

[0232] Optionally, the beam indicated by the beam index in the first value range and the beam indicated by the beam index in the second value range are the same, or are not completely the same, or are completely different.

[0233] Specifically, beam indexes may be predefined for NCP and ECP, respectively. A beam index belonging to a first value range implicitly indicates that a CP type of a symbol of a time domain resource is NCP while indicating a beam. A beam index belonging to a second value range implicitly indicates that a CP type of a symbol of a time domain resource is ECP while indicating a beam.

[0234] For example, if there are beams a, b, c and d, beam indexes 1-8 can be predefined, where the first value unit is 1-4 and the second value range is 5-8; where, if the value of the beam index is 1, it can indicate beam a, and the CP type of the symbol of the time domain resource of beam a is NCP; if the value of the beam index is 2, it can indicate beam b, and the CP type of the symbol of the time domain resource of beam b is NCP; if the value of the beam index is 3, it can indicate beam c, and the CP type of the symbol of the time domain resource of beam c is NCP; if the value of the beam index is 4, it can be To indicate beam d, and the CP type of the symbols of the time domain resources of beam d is NCP; if the value of the beam index is 5, it can indicate beam a, and the CP type of the symbols of the time domain resources of beam a is ECP; if the value of the beam index is 6, it can indicate beam b, and the CP type of the symbols of the time domain resources of beam b is ECP; if the value of the beam index is 7, it can indicate beam c, and the CP type of the symbols of the time domain resources of beam c is ECP; if the value of the beam index is 8, it can indicate beam d, and the CP type of the symbols of the time domain resources of beam d is ECP.

[0235] Optionally, in some embodiments, the determining the CP type of the symbol of the time domain resource includes one or more of the following:

[0236] Based on the protocol pre-definition, determining the CP type is NCP or ECP;

[0237] or,

[0238] Based on protocol predefinition, when the CP type supported by the NCR is NCP, determining that the CP type of the symbol of the time domain resource is NCP;

[0239] or,

[0240] Based on protocol pre-definition, when the NCR does not support the value of the reference subcarrier spacing corresponding to the ECP, determine that the CP type of the symbol of the time domain resource is NCP;

[0241] or,

[0242] Determining that the CP type is the same as a CP type of a downlink control channel of a preset type;

[0243] or

[0244] Determining that the CP type is the same as the CP type of a downlink control channel carrying common control information;

[0245] or

[0246] Determining that the CP type is the same as the CP type of the bandwidth part BWP where the NCR control link is located;

[0247] or

[0248] Determine that the CP type is the same as the CP type corresponding to the PDCCH of the DCI used to carry beam indication information;

[0249] or

[0250] Determine that the CP type is the same as the CP type corresponding to the PDSCH of the MAC CE carrying the activated beam indication information.

[0251] Optionally, the method for determining the CP type of the symbol of the time domain resource may further include at least one of the following (1)-(8):

[0252] (1) Based on the protocol pre-definition, determine that the CP type is NCP or ECP;

[0253] (2) based on protocol pre-definition, when the CP type supported by the NCR is NCP, determining that the CP type of the symbol of the time domain resource is NCP;

[0254] For example, the protocol may clearly state that NCR only supports NCP.

[0255] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP type of the symbol of the time domain resource is NCP.

[0256] (3) based on protocol pre-definition, when the NCR does not support the value of the reference subcarrier spacing corresponding to the ECP, determining that the CP type of the symbol of the time domain resource is NCP;

[0257] For example, the protocol may clearly state that NCR only supports NCP but not ECP.

[0258] For example, the agreement can clearly state that NCR does not support ECP.

[0259] For example, the agreement can clearly state that NCR does not support ECP

[0260] For example, since ECP is configurable only in FR1, SCS=60kHz, it can be implicitly stated that NCR only supports NCP by pre-defining that SCS does not support 60kHz in FR1 through regulation or protocol.

[0261] (4) determining that the CP type is the same as the CP type of a downlink control channel of a preset type;

[0262] For example, the protocol may declare that the CP type of the symbol of the time domain resource is consistent with the CP type of the type0 PDCCH.

[0263] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP type of the symbols of the time domain resource is consistent with the CP type of the type0 PDCCH.

[0264] (5) determining that the CP type is the same as the CP type of a downlink control channel carrying common control information;

[0265] (6) determining that the CP type is the same as the CP type of the bandwidth part BWP where the NCR control link is located;

[0266] For example, the CP type may be consistent with the CP type of the bandwidth part BWP where the NCR control link is located, that is, the CP type used by the C-link.

[0267] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP type of the symbols of the time domain resource may be consistent with the CP type of the BWP where the C-LINK is located.

[0268] For example, the CP type of the symbol of the time domain resource may be consistent with the CP type of the BWP currently activated by the NCR, that is, the CP type used by the C-link.

[0269] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP type of the symbols of the time domain resource is consistent with the CP type of the BWP where the C-LINK is located.

[0270] (7) determining that the CP type is the same as the CP type corresponding to the PDCCH of the DCI used to carry the beam indication information;

[0271] For example, the CP type of the symbol of the time domain resource may be consistent with the CP type used by the PDCCH carrying the DCI or the PDSCH activated by the MAC-CE;

[0272] For example, when the NCR determines time resource parameters, such as determining symbol offset and / or number of continuous symbols, the CP type of the symbols of the time domain resource is consistent with the CP type of the BWP (indicated by the period) in which the C-LINK is located;

[0273] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP type of the symbols of the time domain resource is consistent with the CP type of the PDCCH carrying the DCI (through aperiodic indication);

[0274] For example, when the NCR determines time resource parameters, such as determining symbol offset and / or number of continuous symbols, the CP type of the symbols of the time domain resource is consistent with the CP type used by the PDSCH activated by the MAC-CE (through semi-static indication).

[0275] (8) Determine that the CP type is the same as the CP type corresponding to the PDSCH of the MAC CE carrying the activated beam indication information.

[0276] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a continuous symbol number, the CP type of the symbol of the time domain resource is consistent with the CP type of the PDSCH carrying the activation beam indication information.

[0277] In some embodiments, the method of explicitly indicating the CP type is implemented as follows:

[0278] The NCR may be provided by NCR PeriodicFwdResourceSetToAddModList, which is a set of resources used to access transmission or reception on the link. The set of resources in the resource set list is provided by NCRPeriodicFwdResourceSet and occurs with a period provided by NCR periodicity. The resources in the resource set are provided by NCR PeriodicFwdResource and consist of a pair of time resources provided by NCR PeriodicTimeResource and a beam with an index provided by NCR beamIndex [20, TS 38.106]. The time resource starts from a slot that is offset by slotOffsetPeriodic slots from the start of the resource set period, starts from a symbol that is offset by symbolOffset symbols from the start of the slot, and has a duration provided by durationInSymbols, all based on the SCS provided by ncr referenceSCS and the Normal CP type definition.

[0279] Among them, the Normal CP type can also be replaced by the CP type of Type 0PDCCH.

[0280] The NCR can provide a list of resource sets for transmission or reception on the access link by NCR Semi-PersistentFWdResourceSetToAddModList. The MAC CE command can instruct the NCR to use or stop using the resource set based on the corresponding identifier provided by NCR Semi PersistentWdResources SetId [11, TS 38.321] from the time slot Starting from the first slot after k, where k is the slot in which the NCR-MT will transmit a PUCCH with HARQ-ACK information associated with the PDSCH providing the MAC CE command and μ is the SCS configuration used for PUCCH transmission.

[0281] Among them, the Normal CP type can also be replaced by the CP type of Type 0PDCCH.

[0282] The NCR-MT can be configured to monitor the PDCCH according to the USS set for detecting DCI format 2_8 with CRC scrambled by the NCR-RNTI. The time resources and corresponding beam indices for transmission or reception on the access link are indicated by the corresponding fields in DCI format 2_8 [4, TS 38.212]. When the NCR detects that there is overlap in the time resources indicated by multiple DCI formats 2_8, thereby indicating multiple beam indices on a group of symbols, the group of symbols will use the beam index indicated by the DCI format 2_8 detected by the NCR-MT in the most recent PDCCH monitoring opportunity. The time domain resources start from a time slot that is offset by slotOffsetSemiPersistent time slots from the start of the period of the resource set, start from a symbol that is offset by symbolOffset symbols from the start of the time slot, and have a duration provided by the duration symbol, all of which are based on the SCS provided by the ncr referenceSCS and the Normal CP type definition. The reference time slot is a time slot after the time slot where the PDCCH of DCI format 2_8 is received, and the number of time slots between the two is indicated by FG ​​43-3.

[0283] Among them, the Normal CP type can also be replaced by the CP type of Type 0PDCCH.

[0284] In some embodiments, the method of explicitly indicating the CP type is implemented as follows:

[0292] In some embodiments, the method of explicitly indicating the CP type is implemented as follows:

[0293]

[0294]

[0295]

[0296]

[0297] Optionally, in some embodiments, the method further comprises:

[0298] Based on the time domain resources, determining a time domain position of beam switching;

[0299] The length of the time domain resource is an integer multiple of a first preset length.

[0300] Optionally, when the time domain resources indicated by different beam indication information overlap and the CP types are different, it is necessary to further determine the time domain position of the beam switching.

[0301] Specifically, restrictions can be imposed on the configuration of time resources. For example, since ECP can only appear in FR1, the granularity of FR1's time resource can be limited to an integer multiple of 0.5ms. In this way, the time domain position of the beam switching can be exactly at the boundary of the time unit of the time domain resources indicated by different beam indication information, without affecting the switching of the beam indicated by the time domain resources.

[0302] Optionally, in some embodiments, the first preset length is determined based on a common multiple of a length of a time unit corresponding to the NCP and a length of a time unit corresponding to the ECP.

[0303] Alternatively, if Figure 2 As shown, only the integer multiples of 0.5 ms are aligned at the position boundaries under different CP types, so the first preset length may be 0.5 ms.

[0304] Optionally, the first preset length may be 1 ms.

[0305] Optionally, the first preset length may be a multiple of 0.5 ms.

[0306] Optionally, in some embodiments, the method further comprises:

[0307] In a case where it is determined that the time domain resources of the first beam overlap with the time domain resources of the second beam, performing one or more of the following:

[0308] Sending or receiving the beam based on a time domain resource of the first beam and / or a direction of the first beam;

[0309] or

[0310] Performing beam switching based on a preset switching cycle;

[0311] or

[0312] Determining a time domain position of beam switching based on a time unit boundary of a time domain resource of the first beam; performing beam switching at the time domain position of beam switching;

[0313] or

[0314] Determine a time domain position of beam switching based on a first time unit boundary; perform beam switching at the time domain position of beam switching; wherein the first time unit boundary is a time unit boundary of a time domain resource of a beam transmitted before beam switching;

[0315] or

[0316] Based on the second time unit boundary, determine the time domain position of beam switching; at the time domain position of beam switching, perform beam switching; wherein the second time unit boundary is the time unit boundary of the time domain resource of the beam transmitted after beam switching;

[0317] or

[0318] Determining a time domain position of beam switching based on a time unit boundary of a time domain resource of the second beam; performing beam switching at the time domain position of beam switching;

[0319] The beam indicated by the beam indication information includes the first beam and the second beam, and the priority of the first beam is higher than the priority of the second beam.

[0320] Specifically, when the time domain resources indicated by different beam indication information overlap and the CP types are different, it is necessary to further determine the time domain position of the beam switching;

[0321] Taking the time period of 0.5ms as an example, it can be assumed that the beam indication information of different scenarios overlaps in time domain, and the beam switching position needs to be determined; for example, the time resource of the priority beam indication is not fully included in the high-priority beam indication, and it is necessary to determine whether to perform beam switching and the location of the beam switching.

[0322] For example, when it is determined that the time domain resources of the first beam overlap with the time domain resources of the second beam, at least one of the following (1)-(5) may be performed:

[0323] (1) sending or receiving the beam based on a time domain resource of the first beam and / or a direction of the first beam;

[0324] For example, if the time domain resources of the low priority beam are completely contained in the time domain resources of the high priority beam, the beam direction is directly determined according to the high priority beam information;

[0325] (2) Performing beam switching based on a preset switching period;

[0326] For example, the preset switching period may be 0.5 ms or 1 ms or a multiple of 0.5 ms.

[0327] Figure 4 is one of the schematic diagrams of the time domain resources of the first beam and the second beam provided in an embodiment of the present application, Figure 5 2 is a schematic diagram of time domain resources of the first beam and the second beam provided in an embodiment of the present application. Figure 6 3 is a schematic diagram of the time domain resources of the first beam and the second beam provided in an embodiment of the present application, such as Figures 4 to 6 As shown, when beams with inconsistent CP types indicate overlap in the time domain, the beam switching of the Access link is performed according to the boundary of 0.5 ms.

[0328] (3) determining a time domain position for beam switching based on a time unit boundary of a time domain resource of the first beam; and performing beam switching at the time domain position for beam switching;

[0329] Optionally, the time domain position of the beam switching may be determined based on a time unit boundary of a beam with a higher priority among beams transmitted respectively before and after the beam switching.

Figure 8 FIG5 is a fifth schematic diagram of time domain resources of the first beam and the second beam provided in an embodiment of the present application. Fig. 9 This is a sixth schematic diagram of the time domain resources of the first beam and the second beam provided in an embodiment of the present application, such as Figures 7 to 9 As shown, when beams with inconsistent CP types indicate overlap in the time domain, switching is performed according to the high-priority slot or symbol boundary.

[0331] (4) determining a time domain position of beam switching based on a first time unit boundary; and performing beam switching at the time domain position of beam switching; wherein the first time unit boundary is a time unit boundary of a time domain resource of a beam transmitted before beam switching;

[0332] (5) determining a time domain position of beam switching based on a second time unit boundary; and performing beam switching at the time domain position of beam switching; wherein the second time unit boundary is a time unit boundary of a time domain resource of a beam transmitted after beam switching;

Fig.11 FIG8 is a schematic diagram of time domain resources of the first beam and the second beam provided in an embodiment of the present application. Fig.12 This is a ninth schematic diagram of the time domain resources of the first beam and the second beam provided in an embodiment of the present application, such as Figures 10 to 12 As shown, when the beam indication time domains of inconsistent CP types overlap, switching can be performed according to the slot or symbol boundary of the beam indication to be switched to, giving priority to ensuring the integrity of the high-priority beam indication time domain area.

[0334] (6) determining a time domain position for beam switching based on a time unit boundary of a time domain resource of the second beam; and performing beam switching at the time domain position for beam switching;

[0335] The beam indicated by the beam indication information includes the first beam and the second beam, and the priority of the first beam is higher than the priority of the second beam.

[0336] Optionally, in some embodiments, the preset switching period is determined based on a common multiple of a length of a time unit corresponding to the NCP and a length of a time unit corresponding to the ECP.

[0337] Alternatively, if Figure 2 As shown, under different CP types, only the position boundaries of integer multiples of 0.5 ms are aligned, so the preset switching period can be 0.5 ms.

[0338] Optionally, the preset switching period may be 1 ms.

[0339] Optionally, the preset switching period may be a multiple of 0.5 ms.

[0340] Optionally, in some embodiments, the method further comprises:

[0341] In a case where the CP type is ECP, configuring the ECP based on a starting time unit and / or a time domain resource length indicated by the time domain resource;

[0342] In the case where the start time unit and / or the time domain resource length exceeds the valid configuration range of the ECP, perform one or more of the following:

[0343] Ignore the beam indication information;

[0344] or

[0345] Ignore the starting time unit and / or the time domain resource length indicated by the time domain resource, and send or receive the beam based on a preset starting time unit and / or a preset time domain resource length;

[0346] or

[0347] Based on the starting time unit and / or time domain resource length indicated by the time domain resource, obtain the starting time unit and / or time domain resource length applicable to ECP, and based on the starting time unit and / or time domain resource length applicable to ECP, send or receive the beam.

[0348] Since the configuration ranges of the parameters defined for time resource: the start symbol (configured by the symbol deviation within a time slot) and the duration (configured by the number of symbols) are designed based on NCP, if these parameters are used directly to configure ECP, the configuration values ​​may exceed the valid value range. In this case, how to indicate the configuration parameters of ECP based on the configuration parameters of NCP needs to be defined.

[0349] In the embodiment of the present application, if the parameters defined by the time resource are directly configured for ECP and the configured value exceeds the valid value range, at least one of the following methods (1)-(3) can be used:

[0350] (1) Ignore the beam indication information;

[0351] For example, the beam indication information may be directly indicated according to the parameters corresponding to the existing NCP. If the valid value configuration range is exceeded, the beam indication information may be considered invalid.

[0352] (2) ignoring the starting time unit and / or the time domain resource length indicated by the time domain resource, and sending or receiving the beam based on a preset starting time unit and / or a preset time domain resource length;

[0353] For example, it can be directly indicated according to the parameters corresponding to the existing NCP. If it exceeds the configurable range, it can be based on a preset value, such as a preset start time unit and / or a preset time domain resource length, or a maximum or minimum valid value of a preset start time unit, or a maximum or minimum valid value of a preset time domain resource length.

[0354] (3) Based on the starting time unit and / or time domain resource length indicated by the time domain resource, obtain the starting time unit and / or time domain resource length applicable to the ECP, and send or receive the beam based on the starting time unit and / or time domain resource length applicable to the ECP.

[0355] For example, the existing NCP parameters can be directly indicated, and the ECP configuration parameters can be confirmed through formula conversion.

[0356] Optionally, in some embodiments, acquiring a starting time unit and / or a time domain resource length applicable to the ECP based on the starting time unit and / or the time domain resource length indicated by the time domain resource includes one or more of the following:

[0357] Based on the formula Calculate and obtain a start time unit N' applicable to the ECP, where N is the start time unit indicated by the time domain resource;

[0358] or

[0359] Based on the formula A starting time unit T' applicable to the ECP is calculated, where T is the starting time unit indicated by the time domain resource.

[0360] For example, if the NCP parameter is configured as N, then the actual configuration value is N for NCP, and the actual configuration value is N for ECP.

[0361] Fig.13 This is the second flow chart of the resource determination method provided in the embodiment of the present application, such as Fig.13 As shown, the method is applied to a base station, and the method comprises the following steps:

[0362] Step 1300, sending beam indication information;

[0363] Among them, the beam indication information is used to indicate the beam-related information of the access link of the NCR, and the beam-related information includes time domain resources; the beam indication information and the CP type of the symbol of the time domain resource are used to determine the symbol length of the time domain resource and the beam index on the time domain resource.

[0364] Specifically, to improve the reception performance on the terminal side, the base station can send beam indication information to the NCR to indicate the beamforming transmission resources of the Access link;

[0365] Specifically, in order to determine the symbol length of the time domain resource and the beam index on the time domain resource, it is necessary to first determine the CP type of the symbol of the time domain resource corresponding to the beam indicated by the beam indication information.

[0366] Specifically, after obtaining the beam indication information and the CP type, the symbol length of the time domain resource and the beam index on the time domain resource can be further determined to perform beam shaping.

[0367] The embodiment of the present application designs a solution for determining the CP type of the Access link beam indication information of the NCR and the situation when the beam indication information overlaps in time domain and the CP types are different. It is used to determine the CP type in the beam indication information and how to determine the beam switching position when the beam indication information of different CP types overlaps in time domain, clarifies the transmission resources of the Accesslink beam, and improves the communication quality.

[0368] The resource determination method provided in the embodiment of the present application first determines the CP type of the symbol of the time domain resource corresponding to the beam indicated by the beam indication information, and determines the symbol length of the time domain resource and the beam index on the time domain resource based on the beam indication information and / or the CP type of the symbol, thereby clarifying the transmission resources of the beam of the Access link and improving the communication quality.

[0369] Optionally, in some embodiments, the beam indication information is specifically used to indicate one or more of the following:

[0370] Beam index, time domain resources, reference subcarrier spacing, CP type.

[0371] Specifically, different types of Access link beam indications can include the following information:

[0372] (1) beam index;

[0373] (2) Time domain resources, including starting time slot, starting symbol, and duration;

[0374] Optionally, the starting time slot may be configured by a time slot offset within a cycle;

[0375] Optionally, the start symbol may be configured by a symbol offset within a time slot;

[0376] Optionally, the duration may be configurable by the number of symbols;

[0377] (3) referencing the SCS to determine the OFDM symbol length, where the OFDM symbol length does not include CP length information;

[0378] Specifically, the CP length information needs to be determined according to the CP type.

[0379] Therefore, the CP type can also be determined by explicit or implicit indication of beam indication information.

[0380] Optionally, in some embodiments, the beam indication information includes CP type indication information; the CP type indication information is used to indicate the CP type of the symbol of the time domain resource.

[0381] Specifically, the CP type can be explicitly indicated through beam indication information;

[0382] For example, it can be consistent with the SCS configuration method on each time resource;

[0383] For example, the CP type may be indicated by a CP type indication information;

[0384] For example, periodic, semi-static, and non-periodic beam indication information are configured with their respective CP types through RRC signaling.

[0385] Optionally, in some embodiments, when the value of the reference subcarrier spacing indicated by the beam indication information is a first preset value, the CP type of the symbol of the time domain resource is indicated by the beam indication information; or the CP type of the symbol of the time domain resource is based on a default CP type indication.

[0386] Specifically, the first preset value may be SCS=60 KHz, or other reference subcarrier spacing applicable to ECP, which is not limited in the embodiments of the present application.

[0387] Specifically, a default CP type can be predefined, and NCP can be confirmed as the default CP type. The base station configures the CP type only when ECP needs to be used;

[0388] Specifically, a default CP type can be predefined, and ECP can be confirmed as the default CP type. The base station configures the CP type only when NCP needs to be used;

[0389] For example, taking the default CP type as NCP, the CP type of the symbol of the time domain resource is configured, such as NCP or ECP, only when the reference SCS indicated by the beam indication information is SCS=60KHz; otherwise, the default CP type is NCP.

[0390] For example, taking the default CP type as NCP, after the NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS = 60KHz, the CP type of the symbol of the time domain resource is determined to be NCP or ECP based on the beam indication information; otherwise, the default CP type is NCP, wherein the beam indication information can indicate the CP type implicitly or explicitly, which will not be repeated here.

[0391] For example, taking the default CP type as NCP, after the NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS=60KHz (ECP), the CP type of the symbol of the time domain resource is determined to be ECP based on the beam indication information; otherwise, the default CP type is NCP.

[0392] For example, taking the default CP type as NCP, after NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS = 60KHz (ECP), the CP type of the symbol of the time domain resource is determined based on the CP type indication information in the beam indication information; otherwise, the default CP type is NCP.

[0393] Optionally, in some embodiments, when the beam indication information includes CP type indication information, the CP type of the symbol of the time domain resource is indicated by the CP type indication information; or the CP type of the symbol of the time domain resource is based on a default CP type indication.

[0394] Specifically, a default CP type can be predefined, and NCP can be confirmed as the default CP type. The base station configures the CP type only when ECP needs to be used;

[0395] Specifically, a default CP type can be predefined, and ECP can be confirmed as the default CP type. The base station configures the CP type only when NCP needs to be used;

[0396] For example, taking the default CP type as NCP, a CP type indication information is configured only when the reference SCS indicated by the beam indication information is SCS=60KHz, to indicate that the CP type of the symbol of the time domain resource is NCP or ECP; otherwise the default CP type is NCP.

[0397] For example, taking the default CP type as NCP as an example, a CP type indication information is configured only when ECP needs to be used, to indicate that the CP type of the symbol of the time domain resource is NCP or ECP; otherwise, the default CP type is NCP.

[0398] For example, taking the default CP type as NCP, after the NCR receives the beam indication information, when the beam indication information includes CP type indication information, the CP type of the symbol of the time domain resource is determined to be NCP or ECP based on the beam indication information; otherwise, the default CP type is NCP.

[0399] Optionally, in some embodiments, the default CP type is NCP.

[0400] Optionally, in some embodiments, when the value of the reference subcarrier spacing indicated by the beam indication information is a second preset value, the CP type of the symbol of the time domain resource is NCP; or,

[0401] When the value of the reference subcarrier spacing indicated by the beam indication information is a third preset value, the CP type of the symbol of the time domain resource is ECP.

[0402] Specifically, compared with the related technology, an SCS configuration value can be added: a third preset value; when the base station needs to use ECP, the third preset value can be indicated in the beam indication information; after receiving the beam indication information, the NCR determines that the SCS indicated in the beam indication information is the third preset value, and then the CP type of the symbol of the time domain resource can be determined to be ECP. After receiving the beam indication information, the NCR determines that the SCS indicated in the beam indication information is other configuration values ​​(i.e., the second preset value), and then the CP type of the symbol of the time domain resource can be determined to be NCP.

[0403] Specifically, the third preset value may be SCS=60KHz (ECP), or other reference subcarrier spacing applicable to ECP, which is not limited in the embodiment of the present application.

[0404] Specifically, the second preset value may be a configuration value of other reference subcarrier spacing except the third preset value, which is not limited in the embodiment of the present application.

[0405] For example, compared with the related technology, an SCS configuration value can be added: SCS=60kHz (ECP) as the third preset value; when the base station needs to use ECP, it can indicate SCS=60KHz (ECP) in the beam indication information; after receiving the beam indication information, the NCR determines that the SCS indicated in the beam indication information is 60KHz (ECP), and then it can be determined that the CP type of the symbol of the time domain resource is ECP. After receiving the beam indication information, the NCR determines that the SCS indicated in the beam indication information is other configuration values, and then it can be determined that the CP type of the symbol of the time domain resource is NCP.

[0406] Optionally, in some embodiments, the third preset value is used to indicate that the reference subcarrier spacing and the CP type are ECP.

[0407] Optionally, the third preset value includes 60KHzECP.

[0408] Optionally, the third preset value is a reference subcarrier spacing associated with the ECP.

[0409] Specifically, the third preset value is different from the second preset value, that is, the second preset value may be a configuration value of other reference subcarrier spacings except 60 KHz ECP.

[0410] Specifically, the third preset value is different from the second preset value, that is, the second preset value may be a configuration value of other reference subcarrier spacings except the reference subcarrier spacing associated with the ECP.

[0411] Optionally, in some embodiments, when the value of the beam index indicated by the beam indication information belongs to the first value range, the CP type of the symbol of the time domain resource is NCP; or,

[0412] When the value of the beam index indicated by the beam indication information belongs to the second value range, the CP type of the symbol of the time domain resource is ECP.

[0413] Optionally, the beam indicated by the beam index in the first value range and the beam indicated by the beam index in the second value range are the same, or are not completely the same, or are completely different.

[0414] Specifically, beam indexes may be predefined for NCP and ECP, respectively. A beam index belonging to a first value range implicitly indicates that a CP type of a symbol of a time domain resource is NCP while indicating a beam. A beam index belonging to a second value range implicitly indicates that a CP type of a symbol of a time domain resource is ECP while indicating a beam.

[0415] For example, if there are beams a, b, c and d, beam indexes 1-8 can be predefined, where the first value unit is 1-4 and the second value range is 5-8; where, if the value of the beam index is 1, it can indicate beam a, and the CP type of the symbol of the time domain resource of beam a is NCP; if the value of the beam index is 2, it can indicate beam b, and the CP type of the symbol of the time domain resource of beam b is NCP; if the value of the beam index is 3, it can indicate beam c, and the CP type of the symbol of the time domain resource of beam c is NCP; if the value of the beam index is 4, it can be To indicate beam d, and the CP type of the symbols of the time domain resources of beam d is NCP; if the value of the beam index is 5, it can indicate beam a, and the CP type of the symbols of the time domain resources of beam a is ECP; if the value of the beam index is 6, it can indicate beam b, and the CP type of the symbols of the time domain resources of beam b is ECP; if the value of the beam index is 7, it can indicate beam c, and the CP type of the symbols of the time domain resources of beam c is ECP; if the value of the beam index is 8, it can indicate beam d, and the CP type of the symbols of the time domain resources of beam d is ECP.

[0416] Optionally, in some embodiments, the CP type is predefined by the protocol as NCP or ECP;

[0417] or,

[0418] In the case where the CP type supported by the NCR is NCP, the CP type of the symbol of the time domain resource is predefined by the protocol as NCP;

[0419] or,

[0420] In the case where the NCR does not support the value of the reference subcarrier spacing corresponding to the ECP, the CP type of the symbol of the time domain resource is predefined by the protocol as NCP;

[0421] or,

[0422] The CP type is the same as the CP type of a downlink control channel of a preset type;

[0423] or

[0424] The CP type is the same as the CP type of the downlink control channel carrying the common control information;

[0425] or

[0426] The CP type is the same as the CP type of the bandwidth part BWP where the NCR control link is located;

[0427] or

[0428] The CP type is the same as the CP type corresponding to the PDCCH of the DCI used to carry the beam indication information;

[0429] or

[0430] The CP type is the same as the CP type corresponding to the PDSCH of the MAC CE carrying the activated beam indication information.

[0431] Optionally, the method for determining the CP type of the symbol of the time domain resource may further include at least one of the following (1)-(8):

[0432] (1) Based on the protocol pre-definition, determine that the CP type is NCP or ECP;

[0433] (2) based on protocol pre-definition, when the CP type supported by the NCR is NCP, determining that the CP type of the symbol of the time domain resource is NCP;

[0434] For example, the protocol may clearly state that NCR only supports NCP.

[0435] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP type of the symbol of the time domain resource is NCP.

[0436] (3) based on protocol pre-definition, when the NCR does not support the value of the reference subcarrier spacing corresponding to the ECP, determining that the CP type of the symbol of the time domain resource is NCP;

[0437] For example, the protocol may clearly state that NCR only supports NCP but not ECP.

[0438] For example, the agreement can clearly state that NCR does not support ECP.

[0439] For example, the agreement can clearly state that NCR does not support ECP

[0440] For example, since ECP is configurable only in FR1, SCS=60kHz, it can be implicitly stated that NCR only supports NCP by pre-defining that SCS does not support 60kHz in FR1 through regulation or protocol.

[0441] (4) determining that the CP type is the same as the CP type of a downlink control channel of a preset type;

[0442] For example, the protocol may declare that the CP type of the symbol of the time domain resource is consistent with the CP type of the type0 PDCCH.

[0443] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP type of the symbols of the time domain resource is consistent with the CP type of the type0 PDCCH.

[0444] (5) determining that the CP type is the same as the CP type of a downlink control channel carrying common control information;

[0445] (6) determining that the CP type is the same as the CP type of the bandwidth part BWP where the NCR control link is located;

[0446] For example, the CP type may be consistent with the CP type of the bandwidth part BWP where the NCR control link is located, that is, the CP type used by the C-link.

[0447] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP type of the symbols of the time domain resource may be consistent with the CP type of the BWP where the C-LINK is located.

[0448] For example, the CP type of the symbol of the time domain resource may be consistent with the CP type of the BWP currently activated by the NCR, that is, the CP type used by the C-link.

[0449] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP type of the symbols of the time domain resource is consistent with the CP type of the BWP where the C-LINK is located.

[0450] (7) determining that the CP type is the same as the CP type corresponding to the PDCCH of the DCI used to carry the beam indication information;

[0451] For example, the CP type of the symbol of the time domain resource may be consistent with the CP type used by the PDCCH carrying the DCI or the PDSCH activated by the MAC-CE;

[0452] For example, when the NCR determines time resource parameters, such as determining symbol offset and / or number of continuous symbols, the CP type of the symbols of the time domain resource is consistent with the CP type of the BWP (indicated by the period) in which the C-LINK is located;

[0453] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP type of the symbols of the time domain resource is consistent with the CP type of the PDCCH carrying the DCI (through aperiodic indication);

[0454] For example, when the NCR determines time resource parameters, such as determining symbol offset and / or number of continuous symbols, the CP type of the symbols of the time domain resource is consistent with the CP type used by the PDSCH activated by the MAC-CE (through semi-static indication).

[0455] (8) Determine that the CP type is the same as the CP type corresponding to the PDSCH of the MAC CE carrying the activated beam indication information.

[0456] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a continuous symbol number, the CP type of the symbol of the time domain resource is consistent with the CP type of the PDSCH carrying the activation beam indication information.

[0457] Optionally, in some embodiments, the length of the time domain resource is an integer multiple of a first preset length.

[0458] Optionally, when the time domain resources indicated by different beam indication information overlap and the CP types are different, it is necessary to further determine the time domain position of the beam switching.

[0459] Specifically, restrictions can be imposed on the configuration of time resources. For example, since ECP can only appear in FR1, the granularity of FR1's time resource can be limited to an integer multiple of 0.5ms. In this way, the time domain position of the beam switching can be exactly at the boundary of the time unit of the time domain resources indicated by different beam indication information, without affecting the switching of the beam indicated by the time domain resources.

[0460] Optionally, in some embodiments, the first preset length is determined based on a common multiple of a length of a time unit corresponding to the NCP and a length of a time unit corresponding to the ECP.

[0461] Alternatively, if Figure 2As shown, only the integer multiples of 0.5 ms are aligned at the position boundaries under different CP types, so the first preset length may be 0.5 ms.

[0462] Optionally, the first preset length may be 1 ms.

[0463] Optionally, the first preset length may be a multiple of 0.5 ms.
