Description

Resource determination method and device

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311457779.5, filed on November 3, 2023, entitled “Resource Determination Method and Apparatus,” which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to the field of wireless communication technologies, and in particular to a resource determination method and device. Background Art

[0004] The main difference between a Network Control Repeater (NCR) and a traditional relay is that the base station can control the network of the NCR it serves. Two links exist between the base station and the NCR: a control link and a backhaul link. There is also an access link between the NCR and the UE.

[0005] Related technologies support access link beamforming to improve terminal reception performance. Access link beam indication information includes a beam index, time domain information, and a reference SCS. Because the access link beam indication information provided by the base station to the NCR does not include the CP configuration, the NCR cannot determine the specific location and length of the corresponding configuration symbol when determining the time domain information corresponding to the configured beam, thus reducing communication quality.

[0239] The technical solution provided by the embodiments of the present disclosure can be applicable to a variety of systems, especially 5G systems. For example, applicable systems may be global system of mobile communication (GSM) systems, code division multiple access (CDMA) systems, wideband code division multiple access (WCDMA) general packet radio service (GPRS) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, long term evolution advanced (LTE-A) systems, universal mobile telecommunication systems (UMTS), worldwide interoperability for microwave access (WiMAX) systems, 5G new air interface (NR) systems, etc. These various systems include terminal devices and network devices. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0240] First, let’s introduce the following contents:

[0241] Figure 1 is a schematic diagram of the NCR link structure provided in related art. As shown in Figure 1, the main difference between a network-controlled repeater (NCR) and a traditional relay is that the base station can exercise network control over the NCR serving it. The figure below illustrates the link relationships between the base station, NCR, and terminal. Two links exist between the base station and NCR: a control link and a backhaul link. There is also an access link between the NCR and the UE.

[0242] In the communication system of the related art, beamforming 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.

[0243] Three types of Access link beam indication information supported in the related art include: periodic indication information, semi-persistent indication information and aperiodic indication information.

[0244] Among them, the beam indication information of the Access link of periodic and semi-persistent indication includes: beam index, 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.

[0245] The beam indication information of the non-periodic access link includes: beam index, 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}), and reference SCS.

[0246] When different types of indication information indicate different beam directions at the same time, i.e., when a conflict occurs, the following principles should be followed:

[0247] When the priority flag is not configured: Aperiodic beam indication > semi-persistent beam indication > periodic beam indication.

[0248] When the priority flag is configured: semi-persistent beam indication and periodic beam indication have higher priority than aperiodic beam indication, and semi-persistent beam indication and periodic beam indication have higher priority than aperiodic beam indication.

[0249] Because the access link beam indication information configured by the base station to the NCR does not include the CP configuration, the NCR cannot determine the specific location and length of the corresponding configuration symbol when determining the time domain information corresponding to the configured beam. Therefore, two problems need to be solved:

[0250] (1) How to determine the CP configuration in the beam indication information (determine whether it is a normal cyclic prefix (NCP) or an extended cyclic prefix (ECP));

[0251] (2) Figure 2 is a schematic diagram of the lengths of various CP types provided by related art. As shown in Figure 2, only the boundaries of positions with integer multiples of 0.5 ms are aligned under different CP configurations. When different beam indication information overlaps in the time domain and the CP configurations differ, how should the beam switching position be determined?

[0252] The embodiments of the present disclosure provide a resource determination method and apparatus to improve communication quality.

[0253] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0254] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0255] FIG3 is a flow chart of a resource determination method according to an embodiment of the present disclosure. As shown in FIG3 , the method is applied to a repeater NCR. The method includes the following steps:

[0256] Step 300: Obtain beam indication information, where the beam indication information is used to indicate beam-related information of the access link of the NCR, and the beam-related information includes time domain resources;

[0257] 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;

[0258] Step 310: Determine a CP configuration for the symbols of the time domain resource;

[0259] 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 configuration of the symbol of the time domain resource corresponding to the beam indicated by the beam indication information.

[0260] 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 configuration of the symbol.

[0261] Specifically, after obtaining the beam indication information and CP configuration, the symbol length of the time domain resource and the beam index on the time domain resource can be further determined to perform beam forming.

[0262] The disclosed embodiment designs a solution for determining the CP configuration 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 configuration is different. It is used to determine the defect of how to determine the beam switching position when the CP configuration in the beam indication information and the beam indication information of different CP configurations overlap in time domain, clarifies the transmission resources of the Access link beam, and improves the communication quality.

[0263] The resource determination method provided by the embodiment of the present disclosure first determines the CP configuration 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 configuration of the symbol, thereby clarifying the transmission resource of the beam of the Access link and improving the communication quality.

[0264] Optionally, in some embodiments, the beam indication information is specifically used to indicate one or more of the following:

[0265] Beam index, time domain resources, reference subcarrier spacing, and CP configuration.

[0266] Specifically, the Access Link beam indication of different configurations can include the following information:

[0267] (1) beam index;

[0268] (2) Time domain resources, including: starting time slot, starting symbol, and duration;

[0269] Optionally, the starting time slot may be configured by a time slot offset within a cycle;

[0270] Optionally, the start symbol may be configured by a symbol offset within a time slot;

[0271] Optionally, the duration can be configurable by the number of symbols;

[0272] (3) Reference SCS is used to determine the OFDM symbol length, where the OFDM symbol length does not include CP length information;

[0273] Specifically, the CP length information needs to be determined according to the CP configuration.

[0274] Therefore, the CP configuration can also be determined by explicit or implicit indication of beam indication information.

[0275] Optionally, in some embodiments, the beam indication information includes CP type indication information;

[0276] The determining the CP configuration of the symbols of the time domain resources includes:

[0277] Based on the CP type indication information, a CP configuration of the symbol of the time domain resource is determined.

[0278] Specifically, the CP configuration can be explicitly indicated through beam indication information;

[0279] For example, it can be consistent with the SCS configuration method on each time resource;

[0280] For example, the CP configuration may be indicated by a CP type indication message;

[0281] For example, periodic, semi-static, and non-periodic beam indication information are configured with their respective CP configurations through RRC signaling.

[0282] In some embodiments, the method for explicitly indicating the CP configuration is implemented as follows:

[0283] Some restrictions can be added during base station configuration:

[0284] For example, the referenceCP-r18 configuration type is the same between different PeriodicFwdResourceSets, that is, they are all extended CP or NCP.

[0285] Optionally, in some embodiments, determining the CP configuration of the symbols of the time domain resources includes:

[0286] When the reference subcarrier spacing is a first preset value, determining a CP configuration of a symbol of the time domain resource based on the beam indication information;

[0287] or

[0288] Based on a default CP configuration, a CP configuration of the symbols of the time domain resource is determined.

[0289] 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 disclosure.

[0290] Specifically, a default CP configuration can be predefined, and NCP can be confirmed as the default CP configuration. The base station will configure the CP configuration only when ECP is required.

[0291] Specifically, a default CP configuration can be predefined, and ECP can be confirmed as the default CP configuration. The base station will configure the CP configuration only when NCP is required.

[0292] For example, taking the default CP configuration as NCP as an example, the CP configuration of the symbol of the time domain resource is configured only when the reference SCS indicated by the beam indication information is SCS=60KHz, such as NCP or ECP; otherwise, the default CP configuration is NCP.

[0293] For example, taking the default CP configuration as NCP as an example, after the NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS = 60KHz, the CP configuration 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 configuration is NCP, where the beam indication information can indicate the CP configuration implicitly or explicitly, which will not be repeated here.

[0294] For example, taking the default CP configuration as NCP as an example, after the NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS = 60KHz (ECP), the CP configuration of the symbol of the time domain resource is determined to be ECP based on the beam indication information; otherwise, the default CP configuration is NCP.

[0295] For example, taking the default CP configuration as NCP as an example, after the NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS = 60KHz (ECP), the CP configuration of the symbol of the time domain resource is determined based on the CP configuration indication information in the beam indication information; otherwise, the default CP configuration is NCP.

[0296] In some embodiments, the method for explicitly indicating the CP configuration is implemented as follows:

[0297] Optionally, in some embodiments, determining the CP configuration of the symbols of the time domain resources includes:

[0298] In a case where the beam indication information includes CP type indication information, determining a CP configuration of a symbol of the time domain resource based on the CP type indication information;

[0299] or

[0300] Based on a default CP configuration, a CP configuration of the symbols of the time domain resource is determined.

[0301] Specifically, a default CP configuration can be predefined, and NCP can be confirmed as the default CP configuration. The base station will configure the CP configuration only when ECP is required.

[0302] Specifically, a default CP configuration can be predefined, and ECP can be confirmed as the default CP configuration. The base station will configure the CP configuration only when NCP is required.

[0303] For example, taking the default CP configuration as NCP as an example, 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 configuration of the symbol of the time domain resource is NCP or ECP; otherwise, the default CP configuration is NCP.

[0304] For example, taking the default CP configuration as NCP as an example, CP type indication information is configured only when ECP is needed to indicate that the CP configuration of the symbol of the time domain resource is NCP or ECP; otherwise, the default CP configuration is NCP.

[0305] For example, taking the default CP configuration as NCP, after the NCR receives the beam indication information, when the beam indication information includes CP type indication information, the CP configuration 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 configuration is NCP.

[0306] Optionally, in some embodiments, the default CP configuration is NCP.

[0307] Optionally, in some embodiments, determining the CP configuration of the symbols of the time domain resources includes:

[0308] When the reference subcarrier spacing is a second preset value, determining that the CP configuration of the symbol of the time domain resource is NCP; or

[0309] When the value of the reference subcarrier spacing is a third preset value, it is determined that the CP configuration of the symbol of the time domain resource is ECP.

[0310] 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 configuration 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 configuration of the symbol of the time domain resource can be determined to be NCP.

[0311] Specifically, the third preset value may be SCS=60 kHz (ECP), or other reference subcarrier spacing applicable to ECP, which is not limited in the embodiment of the present disclosure.

[0312] 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 disclosure.

[0313] For example, compared with the related technology, an SCS configuration value can be added: SCS = 60kHz (ECP) as a 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 configuration 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 configuration of the symbol of the time domain resource is NCP.

[0314] In some embodiments, the method for explicitly indicating the CP configuration is implemented as follows:

[0315] Optionally, in some embodiments, the third preset value is used to indicate that the reference subcarrier spacing and the CP are configured as ECP;

[0316] Optionally, the third preset value includes 60KHzECP.

[0317] Optionally, the third preset value is a reference subcarrier spacing associated with ECP.

[0318] Specifically, the third preset value is different from the second preset value, that is, the second preset value can be a configuration value of other reference subcarrier spacing except 60KHzECP.

[0319] 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.

[0320] Optionally, in some embodiments, determining the CP configuration of the symbols of the time domain resources includes:

[0321] When the value of the beam index falls within the first value range, determining that the CP configuration of the symbol of the time domain resource is NCP; or

[0322] When the value of the beam index belongs to the second value range, the CP configuration of the symbol of the time domain resource is determined to be ECP.

[0323] 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, not completely the same, or all different.

[0324] Specifically, beam indexes can be predefined for NCP and ECP respectively. The beam index belonging to the first value range indicates the beam while implicitly indicating that the CP configuration of the symbol of the time domain resource is NCP. The beam index belonging to the second value range indicates the beam while implicitly indicating that the CP configuration of the symbol of the time domain resource is ECP.

[0325] 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 configuration 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 configuration 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 configuration of the symbol of the time domain resource of beam c is NCP; if the value of the beam index is 4, it can indicate beam c. To indicate beam d, and the CP configuration 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 configuration 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 configuration 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 configuration 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 configuration of the symbols of the time domain resources of beam d is ECP.

[0332] or,

[0333] Determining that the CP configuration is the same as a CP configuration of a downlink control channel of a preset type;

[0334] or

[0335] Determining that the CP configuration is the same as the CP configuration of a downlink control channel carrying common control information; or

[0342] (2) Based on protocol pre-definition, when the CP configuration supported by the NCR is NCP, determining that the CP configuration of the symbol of the time domain resource is NCP;

[0343] For example, the agreement can clearly state that NCR only supports NCP.

[0344] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP of the symbols of the time domain resource is configured as the NCP.

[0345] (3) Based on protocol pre-definition, if the NCR does not support the value of the reference subcarrier spacing corresponding to the ECP, determine that the CP configuration of the symbol of the time domain resource is NCP;

[0346] For example, the agreement can clearly state that NCR only supports NCP and not ECP.

[0347] For example, the agreement can clearly state that NCR does not support ECP.

[0348] For example, the agreement can clearly state that NCR does not support ECP

[0349] For example, since ECP is configurable only in FR1 and SCS=60kHz, it can be implicitly stated that NCR only supports NCP by predefining that SCS does not support 60kHz in FR1 through regulations or protocols.

[0350] (4) determining that the CP configuration is the same as the CP configuration of a preset type of downlink control channel;

[0351] For example, the protocol may declare that the CP configuration of the symbols of the time domain resources is consistent with the CP configuration of the type0 PDCCH.

[0352] For example, when the NCR determines time resource parameters, such as determining the symbol offset and / or the number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration of the type0 PDCCH.

[0354] (6) Determine that the CP configuration is the same as the CP configuration of the bandwidth portion BWP where the NCR control link is located;

[0355] For example, the CP configuration may be consistent with the CP configuration of the bandwidth part BWP where the NCR control link is located, that is, the CP configuration used by the C-link.

[0356] For example, when the NCR determines time resource parameters, such as symbol offset and / or number of continuous symbols, the CP configuration of symbols of the time domain resource may be consistent with the CP configuration of the BWP where the C-LINK is located.

[0357] For example, the CP configuration of the symbols of the time domain resources may be consistent with the CP configuration of the BWP currently activated by the NCR, that is, the CP configuration used by the C-link.

[0358] For example, when the NCR determines time resource parameters, such as symbol offset and / or number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration of the BWP where the C-LINK is located.

[0360] For example, the CP configuration of the symbols of the time domain resources may be consistent with the CP configuration used by the PDCCH carrying the DCI or the PDSCH activated by the MAC-CE;

[0361] For example, when the NCR determines time resource parameters, such as determining the symbol offset and / or the number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration of the BWP (indicated by the period) in which the C-LINK is located;

[0362] For example, when the NCR determines time resource parameters, such as when determining the symbol offset and / or the number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration of the PDCCH carrying the DCI (through the aperiodic indication);

[0363] For example, when the NCR determines time resource parameters, such as symbol offset and / or number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration used by the PDSCH activated by the MAC-CE (through semi-static indication).

[0364] (8) Determine that the CP configuration is the same as the CP configuration corresponding to the PDSCH of the MAC CE carrying the activated beam indication information.

[0365] For example, when the NCR determines the time resource parameters, such as determining the symbol offset and / or the number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration of the PDSCH carrying the activation beam indication information.

[0366] In some embodiments, the method for explicitly indicating the CP configuration is implemented as follows:

[0367] The NCR may be provided by NCR PeriodicFwdResourceSetToAddModList, which is a set of resources used to access transmission or reception on a link. The set of resources in the resource set list is provided by NCR PeriodicFwdResourceSet 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 configuration definition.

[0368] Among them, the Normal CP configuration can also be replaced by the CP configuration of Type 0 PDCCH.

[0369] 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 NCR to use or stop using the resource set.

[0371] The NCR-MT can be configured to monitor the PDCCH according to the USS set to detect DCI format 2_8 with a CRC scrambled by the NCR-RNTI. The time resource and the corresponding beam index 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 the time resources indicated by multiple DCI formats 2_8 overlap, 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 resource starts from a time slot that is offset by slotOffsetSemiPersistent time slots from the start of the resource set period, starts from a symbol that is offset by symbolOffset symbols from the start of the time slot, and has a duration provided by duration symbol, all of which are based on the SCS provided by the ncr referenceSCS and the Normal CP configuration definition.

The resource set is 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 the PUCCH transmission. The resource set is provided by NCR Semi-PersistentFWdResourceSet and occurs with a periodicity provided by NCR periodicity. The resources in the resource set are provided by NCR Semi-PersistentFWdResource and consist of a pair of time resources provided by NCR Semi-PersistentTimeResource and a beam with an index provided by NCR beamIndex, where beamIndex can be updated via MAC CE commands.

The time resource starts from a time slot that is offset by slotOffsetSemiPersistent time slots from the start of the resource set period, starts from a symbol that is offset by symbolOffset symbols from the start of the time slot, and has a duration provided by durationInSymbols, which are defined based on the SCS provided by the ncr referenceSCS and the CP configuration of the BWP where the control link is located. 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.

[0379] 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 NCR to use or stop using the resource set. The resource set is based on the corresponding identifier provided by NCR Semi-PersistentWdResources SetId [11, TS 38.321] from the time slot Starting from the first time slot after k, where k is the time 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. The resource set is provided by NCR Semi-PersistentFWdResourceSet and occurs with a periodicity provided by NCR periodicity. The resources in the resource set are provided by NCR Semi-PersistentFWdResource and include a pair of time resources provided by NCR Semi-PersistentTimeResource and a beam with an index provided by NCR beamIndex, where beamIndex can be updated via MAC CE command. The time resource starts from a slot that is offset by slotOffsetSemiPersistent slots from the start of the resource set's period, starts from a symbol that is offset by symbolOffset symbols from the start of the slot, and has a duration provided by durationInSymbols, based on the SCS provided by ncr-referenceSCS and the CP configuration definition of the PDSCH carrying the activated MAC-CE.

[0380] The NCR-MT can be configured to monitor the PDCCH according to the USS set for detecting DCI format 2_8 with a CRC scrambled by the NCR-RNTI. The time resource and the corresponding beam index 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 the time resources indicated by multiple DCI formats 2_8 overlap, 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 resource starts from a time slot that is offset by slotOffsetSemiPersistent time slots from the start of the resource set period, starts from a symbol that is offset by symbolOffset symbols from the start of the time slot, and has a duration provided by durationInSymbols, which is based on the SCS provided by the ncr-referenceSCS and the CP configuration of the PDCCH carrying the DCI. 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.

[0381] In some embodiments, the method for explicitly indicating the CP configuration is implemented as follows:

[0382] Optionally, in some embodiments, the method further comprises:

[0383] Determining a time domain position for beam switching based on the time domain resources;

[0384] The length of the time domain resource is an integer multiple of a first preset length.

[0385] Optionally, when the time domain resources indicated by different beam indication information overlap and the CP configurations are different, it is necessary to further determine the time domain position of the beam switching.

[0386] Specifically, restrictions can be placed 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 resource indicated by different beam indication information, which will not affect the switching of the beam indicated by the time domain resource.

[0387] 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.

[0388] Optionally, as shown in FIG2 , only the positions of integer multiples of 0.5 ms are aligned at the boundaries under different CP configurations, and the first preset length may be 0.5 ms.

[0389] Optionally, the first preset length may be 1 ms.

[0390] Optionally, the first preset length may be a multiple of 0.5 ms.

[0391] Optionally, in some embodiments, the method further comprises:

[0392] When it is determined that the time domain resources of the first beam overlap with the time domain resources of the second beam, one or more of the following are performed:

[0393] Sending or receiving the beam based on a time domain resource of the first beam and / or a direction of the first beam;

[0394] or

[0395] Performing beam switching based on a preset switching period;

[0396] or

[0397] 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;

[0398] or

[0399] Determining a time domain position for beam switching based on a first time unit boundary; performing beam switching at the time domain position for beam switching; wherein the first time unit boundary is a time unit boundary of a time domain resource of a beam transmitted before the beam switching;

[0400] or

[0401] Determining a time domain position for beam switching based on a second time unit boundary; performing beam switching at the time domain position for 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;

[0402] or

[0403] 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;

[0404] 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.

[0405] Specifically, when the time domain resources indicated by different beam indication information overlap and the CP configurations are different, it is necessary to further determine the time domain position of the beam switching;

[0406] 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.

[0407] 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:

[0408] (1) sending or receiving the beam based on the time domain resource of the first beam and / or the direction of the first beam;

[0409] 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;

[0410] (2) Performing beam switching based on a preset switching period;

[0411] For example, the preset switching period may be 0.5 ms, 1 ms, or a multiple of 0.5 ms.

[0412] 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 disclosure, Figure 5 is a second schematic diagram of the time domain resources of the first beam and the second beam provided in an embodiment of the present disclosure, and Figure 6 is a third schematic diagram of the time domain resources of the first beam and the second beam provided in an embodiment of the present disclosure. As shown in Figures 4 to 6, when the beams with inconsistent CP configurations indicate that there is overlap in the time domain, the beam switching of the Access link is performed according to the 0.5ms boundary.

[0413] (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;

[0414] 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.

As shown in Figures 7 to 9, when the beam indication time domains of inconsistent CP configurations overlap, switching is performed according to the high-priority slot or symbol boundary.

As shown in Figures 10 to 12, when the beam indication time domains with inconsistent CP configurations overlap, switching can be performed according to the slot or symbol boundary of the beam indication to be switched to, and priority is given to ensuring the integrity of the high-priority beam indication time domain area.

[0419] (6) determining a time domain position for beam switching based on a time unit boundary of the time domain resource of the second beam; and performing beam switching at the time domain position for beam switching;

[0420] 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.

[0421] 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.

[0422] Optionally, as shown in FIG2 , only the position boundaries of integer multiples of 0.5 ms are aligned under different CP configurations, and the preset switching period may be 0.5 ms.

[0423] Optionally, the preset switching period may be 1 ms.

[0424] Optionally, the preset switching period may be a multiple of 0.5 ms.

[0425] Optionally, in some embodiments, the method further comprises:

[0426] When the CP is configured as an ECP, configuring the ECP based on a starting time unit and / or a time domain resource length indicated by the time domain resource;

[0427] If 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:

[0428] Ignore the beam indication information;

[0429] or

[0430] 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;

[0431] or

[0432] 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.

[0433] Since the configuration ranges of the parameters defined by the time resource, including the start symbol (configured by the symbol offset within a time slot) and the duration (configured by the number of symbols), are designed based on the NCP, if these parameters are directly used to configure the ECP, the configured values ​​may exceed the valid value range. In this case, how to indicate the ECP configuration parameters based on the NCP configuration parameters needs to be defined.

[0434] In the embodiment of the present disclosure, 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:

[0435] (1) Ignore the beam indication information;

[0436] For example, the beam indication information can be directly indicated according to the parameters corresponding to the existing NCP. If it exceeds the valid value configuration range, the beam indication information can be considered invalid;

[0437] (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 the preset starting time unit and / or the preset time domain resource length;

[0438] 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 the maximum or minimum valid value of the preset start time unit, or the maximum or minimum valid value of the preset time domain resource length.

[0439] (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.

[0440] For example, the existing NCP parameters can be directly indicated, and the ECP configuration parameters can be confirmed through formula conversion.

[0441] 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:

[0442] 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;

[0443] or

[0444] Based on the formula A start time unit T' applicable to the ECP is obtained by calculation, where T is the start time unit indicated by the time domain resource.

[0445] 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.

[0446] FIG13 is a second flow chart of a resource determination method provided in an embodiment of the present disclosure. As shown in FIG13 , the method is applied to a base station, and the method includes the following steps:

[0447] Step 1300: Send beam indication information;

[0448] 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 configuration of the symbols of the time domain resources are used to determine the symbol length of the time domain resources and the beam index on the time domain resources.

[0449] 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;

[0450] 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 configuration of the symbol of the time domain resource corresponding to the beam indicated by the beam indication information.

[0451] Specifically, after obtaining the beam indication information and CP configuration, the symbol length of the time domain resource and the beam index on the time domain resource can be further determined to perform beam forming.

[0452] The disclosed embodiment designs a solution for determining the CP configuration 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 configuration is different. It is used to determine the defect of how to determine the beam switching position when the CP configuration in the beam indication information and the beam indication information of different CP configurations overlap in time domain, clarifies the transmission resources of the Access link beam, and improves the communication quality.

[0453] The resource determination method provided by the embodiment of the present disclosure first determines the CP configuration 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 configuration of the symbol, thereby clarifying the transmission resource of the beam of the Access link and improving the communication quality.

[0454] Optionally, in some embodiments, the beam indication information is specifically used to indicate one or more of the following:

[0455] Beam index, time domain resources, reference subcarrier spacing, and CP configuration.

[0456] Specifically, the Access Link beam indication of different configurations can include the following information:

[0457] (1) beam index;

[0458] (2) Time domain resources, including: starting time slot, starting symbol, and duration;

[0459] Optionally, the starting time slot may be configured by a time slot offset within a cycle;

[0460] Optionally, the start symbol may be configured by a symbol offset within a time slot;

[0461] Optionally, the duration can be configurable by the number of symbols;

[0462] (3) Reference SCS is used to determine the OFDM symbol length, where the OFDM symbol length does not include CP length information;

[0463] Specifically, the CP length information needs to be determined according to the CP configuration.

[0464] Therefore, the CP configuration can also be determined by explicit or implicit indication of beam indication information.

[0465] Optionally, in some embodiments, the beam indication information includes CP type indication information; the CP type indication information is used to indicate the CP configuration of the symbol of the time domain resource.

[0466] Specifically, the CP configuration can be explicitly indicated through beam indication information;

[0467] For example, it can be consistent with the SCS configuration method on each time resource;

[0468] For example, the CP configuration may be indicated by a CP type indication message;

[0469] For example, periodic, semi-static, and non-periodic beam indication information are configured with their respective CP configurations through RRC signaling.

[0470] 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 configuration of the symbol of the time domain resource is indicated by the beam indication information; or the CP configuration of the symbol of the time domain resource is based on a default CP configuration indication.

[0471] 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 disclosure.

[0472] Specifically, a default CP configuration can be predefined, and NCP can be confirmed as the default CP configuration. The base station will configure the CP configuration only when ECP is required.

[0473] Specifically, a default CP configuration can be predefined, and ECP can be confirmed as the default CP configuration. The base station will configure the CP configuration only when NCP is required.

[0474] For example, taking the default CP configuration as NCP as an example, the CP configuration of the symbol of the time domain resource is configured only when the reference SCS indicated by the beam indication information is SCS=60KHz, such as NCP or ECP; otherwise, the default CP configuration is NCP.

[0475] For example, taking the default CP configuration as NCP as an example, after the NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS = 60KHz, the CP configuration 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 configuration is NCP, where the beam indication information can indicate the CP configuration implicitly or explicitly, which will not be repeated here.

[0476] For example, taking the default CP configuration as NCP as an example, after the NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS = 60KHz (ECP), the CP configuration of the symbol of the time domain resource is determined to be ECP based on the beam indication information; otherwise, the default CP configuration is NCP.

[0477] For example, taking the default CP configuration as NCP as an example, after the NCR receives the beam indication information, when the reference SCS indicated by the beam indication information is SCS = 60KHz (ECP), the CP configuration 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 configuration is NCP.

[0478] Optionally, in some embodiments, when the beam indication information includes CP type indication information, the CP configuration of the symbol of the time domain resource is indicated by the CP type indication information; or the CP configuration of the symbol of the time domain resource is based on a default CP configuration indication.

[0479] Specifically, a default CP configuration can be predefined, and NCP can be confirmed as the default CP configuration. The base station will configure the CP configuration only when ECP is required.

[0480] Specifically, a default CP configuration can be predefined, and ECP can be confirmed as the default CP configuration. The base station will configure the CP configuration only when NCP is required.

[0481] For example, taking the default CP configuration as NCP as an example, 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 configuration of the symbol of the time domain resource is NCP or ECP; otherwise, the default CP configuration is NCP.

[0482] For example, taking the default CP configuration as NCP as an example, CP type indication information is configured only when ECP is needed to indicate that the CP configuration of the symbol of the time domain resource is NCP or ECP; otherwise, the default CP configuration is NCP.

[0483] For example, taking the default CP configuration as NCP, after the NCR receives the beam indication information, when the beam indication information includes CP type indication information, the CP configuration 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 configuration is NCP.

[0484] Optionally, in some embodiments, the default CP configuration is NCP.

[0485] 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 configuration of the symbol of the time domain resource is NCP; or,

[0486] When the value of the reference subcarrier spacing indicated by the beam indication information is a third preset value, the CP configuration of the symbol of the time domain resource is ECP.

[0487] 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 configuration 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 configuration of the symbol of the time domain resource can be determined to be NCP.

[0488] Specifically, the third preset value may be SCS=60 kHz (ECP), or other reference subcarrier spacing applicable to ECP, which is not limited in the embodiment of the present disclosure.

[0489] 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 disclosure.

[0490] For example, compared with the related technology, an SCS configuration value can be added: SCS = 60kHz (ECP) as a 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 configuration 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 configuration of the symbol of the time domain resource is NCP.

[0491] Optionally, in some embodiments, the third preset value is used to indicate that the reference subcarrier spacing and the CP are configured as ECP.

[0492] Optionally, the third preset value includes 60KHzECP.

[0493] Optionally, the third preset value is a reference subcarrier spacing associated with ECP.

[0494] Specifically, the third preset value is different from the second preset value, that is, the second preset value can be a configuration value of other reference subcarrier spacing except 60KHzECP.

[0495] 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.

[0496] 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 configuration of the symbol of the time domain resource is NCP; or,

[0497] When the value of the beam index indicated by the beam indication information belongs to the second value range, the CP configuration of the symbol of the time domain resource is ECP.

[0498] 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, not completely the same, or all different.

[0499] Specifically, beam indexes can be predefined for NCP and ECP respectively. The beam index belonging to the first value range indicates the beam while implicitly indicating that the CP configuration of the symbol of the time domain resource is NCP. The beam index belonging to the second value range indicates the beam while implicitly indicating that the CP configuration of the symbol of the time domain resource is ECP.

[0500] 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 configuration 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 configuration 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 configuration of the symbol of the time domain resource of beam c is NCP; if the value of the beam index is 4, it can indicate beam c. To indicate beam d, and the CP configuration 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 configuration 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 configuration 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 configuration 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 configuration of the symbols of the time domain resources of beam d is ECP.

[0501] Optionally, in some embodiments, the CP configuration is predefined by a protocol as NCP or ECP;

[0502] or,

[0503] In a case where the CP configuration supported by the NCR is NCP, the CP configuration of the symbol of the time domain resource is predefined by a protocol as NCP;

[0504] or,

[0505] In the case that the NCR does not support the value of the reference subcarrier spacing corresponding to the ECP, the CP configuration of the symbol of the time domain resource is predefined by the protocol as the NCP;

[0506] or,

[0507] The CP configuration is the same as the CP configuration of a downlink control channel of a preset type;

[0508] or

[0509] The CP configuration is the same as the CP configuration of the downlink control channel carrying public control information;

[0510] or

[0511] The CP configuration is the same as the CP configuration of the bandwidth part BWP where the NCR control link is located;

[0512] or

[0513] The CP configuration is the same as the CP configuration corresponding to the PDCCH of the DCI used to carry beam indication information;

[0514] or

[0515] The CP configuration is the same as the CP configuration corresponding to the PDSCH of the MAC CE carrying the activated beam indication information.

[0516] Optionally, the method for determining the CP configuration of the symbols of the time domain resources may further include at least one of the following (1)-(8):

[0517] (1) Based on the protocol pre-definition, determining whether the CP is configured as NCP or ECP;

[0518] (2) Based on protocol pre-definition, when the CP configuration supported by the NCR is NCP, determining that the CP configuration of the symbol of the time domain resource is NCP;

[0519] For example, the agreement can clearly state that NCR only supports NCP.

[0520] For example, when the NCR determines time resource parameters, such as determining a symbol offset and / or a number of continuous symbols, the CP of the symbols of the time domain resource is configured as the NCP.

[0521] (3) Based on protocol pre-definition, if the NCR does not support the value of the reference subcarrier spacing corresponding to the ECP, determine that the CP configuration of the symbol of the time domain resource is NCP;

[0522] For example, the agreement can clearly state that NCR only supports NCP and not ECP.

[0523] For example, the agreement can clearly state that NCR does not support ECP.

[0524] For example, the agreement can clearly state that NCR does not support ECP

[0525] For example, since ECP is configurable only in FR1 and SCS=60kHz, it can be implicitly stated that NCR only supports NCP by predefining that SCS does not support 60kHz in FR1 through regulations or protocols.

[0526] (4) determining that the CP configuration is the same as the CP configuration of a preset type of downlink control channel;

[0527] For example, the protocol may declare that the CP configuration of the symbols of the time domain resources is consistent with the CP configuration of the type0 PDCCH.

[0528] For example, when the NCR determines time resource parameters, such as determining the symbol offset and / or the number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration of the type0 PDCCH.

[0529] (5) determining that the CP configuration is the same as the CP configuration of the downlink control channel carrying common control information;

[0530] (6) Determine that the CP configuration is the same as the CP configuration of the bandwidth portion BWP where the NCR control link is located;

[0531] For example, the CP configuration may be consistent with the CP configuration of the bandwidth part BWP where the NCR control link is located, that is, the CP configuration used by the C-link.

[0532] For example, when the NCR determines time resource parameters, such as symbol offset and / or number of continuous symbols, the CP configuration of symbols of the time domain resource may be consistent with the CP configuration of the BWP where the C-LINK is located.

[0533] For example, the CP configuration of the symbols of the time domain resources may be consistent with the CP configuration of the BWP currently activated by the NCR, that is, the CP configuration used by the C-link.

[0534] For example, when the NCR determines time resource parameters, such as symbol offset and / or number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration of the BWP where the C-LINK is located.

[0535] (7) Determining that the CP configuration is the same as the CP configuration corresponding to the PDCCH of the DCI used to carry the beam indication information;

[0536] For example, the CP configuration of the symbols of the time domain resources may be consistent with the CP configuration used by the PDCCH carrying the DCI or the PDSCH activated by the MAC-CE;

[0537] For example, when the NCR determines time resource parameters, such as determining the symbol offset and / or the number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration of the BWP (indicated by the period) in which the C-LINK is located;

[0538] For example, when the NCR determines time resource parameters, such as when determining the symbol offset and / or the number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration of the PDCCH carrying the DCI (through the aperiodic indication);

[0539] For example, when the NCR determines time resource parameters, such as symbol offset and / or number of continuous symbols, the CP configuration of the symbols of the time domain resource is consistent with the CP configuration used by the PDSCH activated by the MAC-CE (through semi-static indication).

[0542] Optionally, in some embodiments, the length of the time domain resource is an integer multiple of a first preset length.

[0543] Optionally, when the time domain resources indicated by different beam indication information overlap and the CP configurations are different, it is necessary to further determine the time domain position of the beam switching.

[0544] Specifically, restrictions can be placed 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 resource indicated by different beam indication information, which will not affect the switching of the beam indicated by the time domain resource.

[0545] 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.
