[0374] Please refer to FIG1 , which is a schematic diagram of a network architecture applicable to the present disclosure. As shown in FIG1 , the network architecture includes a terminal 11 and a network device 12, wherein:

[0375] The terminal 11 involved in the embodiments of the present disclosure may refer to a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called User Equipment (UE). A wireless terminal can communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiated Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a Redcap terminal, and other devices.

Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal through one or more sectors on the air interface, or may be called another name.

In some network structures, the network device may include a centralized unit (CU) and a distributed unit (DU), and the centralized unit and the distributed unit may also be geographically separated.

[0377] In the disclosed embodiments, a network device and a terminal may each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission may be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission may be two-dimensional MIMO (2D-MIMO), three-dimensional MIMO (3D-MIMO), full-dimensional MIMO (FD-MIMO), or massive MIMO. It may also be diversity transmission, precoded transmission, or beamforming transmission.

[0378] Before describing the embodiments of the present disclosure, the following briefly introduces the relevant technologies:

[0379] Based on NR's broadcast services, network devices can send the Physical Downlink Control Channel (PDCCH) and Physical Downlink Shared Channel (PDSCH) for broadcast services within the CFR. The CFR can be independently configured through the "cfr-Config MCCH-MTCH" parameter in the System Information Block 20 (SIB20), and its bandwidth can be equal to or greater than the bandwidth of the initial Bandwidth Part (BWP).

[0380] A Redcap UE refers to a terminal with reduced capabilities (which can be called a Type 1 terminal), and the maximum receive bandwidth supported by the Redcap UE is reduced to 20 MHz. The CFR for receiving broadcast services configured by the network device for non-Redcap UEs (which can be called Normal UEs or Type 2 terminals) may be greater than 20 MHz. Therefore, the 3rd Generation Partnership Project (3GPP) reached the following conclusion: When the CFR configured in SIB 20 exceeds the bandwidth capability of the Redcap UE, a separate CFR will be introduced for the Redcap UE (Introduce a separate CFR which can be used when the configured bandwidth for the default CFR in SIB20 exceeds the bandwidth capability of bandwidth limited UEs).

[0381] Based on the above background, the CFR configurations for Redcap UEs and Normal UEs include the following two cases:

[0382] Case 1: Redcap UE CFR = Normal UE CFR (as shown in Figure 2);

[0383] Case 2: Redcap UE CFR < Normal UE CFR (as shown in Figure 3).

[0384] For Case 1, the network device can simultaneously schedule the Redcap UE CFR and the Normal UE CFR to receive broadcast services at the same frequency domain resource location through a broadcast service scheduling signaling, such as Downlink Control Information (DCI).

[0385] For Case 2, due to the different bandwidths and starting PRBs of the Redcap UE CFR and the Normal UE CFR, even if the Redcap UE CFR is within the PRB range of the Normal UE CFR, as shown in Figure 3, the network device cannot simultaneously schedule the Redcap UE CFR and the Normal UE CFR to receive broadcast services at the same frequency domain resource location through a broadcast service scheduling signaling. The specific reasons are analyzed as follows:

[0386] (1) Analyze from the perspective of DCI format 4_0:

[0387] For DCI format 4_0, the length of the frequency domain resource allocation (FDRA) field is To determine, The length of the control resource set 0 (CORESET 0) or the bandwidth of the initial BWP The value of the FDRA field is indicated by the resource indicator value (RIV), which is defined as follows:

[0388] if but

[0389] otherwise

[0390] When L' RBs =L RBs / K,RB' start =RB start / K and when L' RBs will not exceed

[0391] That is, after the terminal decodes the RIV indication in the FDRA field, it can solve L' based on the definition of RIV. RBs and RB′ start Then, the frequency domain resource length L is obtained by multiplying it with the scaling factor K. RB and frequency domain resource starting position RB start The scaling factor K is determined as follows: if the CFR bandwidth N CFR satisfy but Otherwise, K = 1. RB start It is determined by taking the lowest resource block (RB) of the CFR as the reference physical resource block (PRB).

[0392] When Redcap UE CFR is configured independently, it calculates K and RB startThe value may be different from that of Normal UE. This will cause the frequency domain resource location information decoded by Redcap UE to be different from that decoded by Normal UE when reading the RIV indication in the FDRA field. Therefore, the network equipment cannot simultaneously schedule Redcap UE CFR and Normal UE CFR to receive broadcast services at the same frequency domain resource location through a DCI format 4_0.

[0393] (2) Multicast service

[0394] A network device schedules a group of terminals to receive multicast services using DCI format 4_1 or DCI format 4_2. The FDRA field length and indication method of DCI format 4_1 are the same as those of DCI format 4_0. The FDRA field of DCI format 4_2 has three types: resource indication type 0, resource indication type 1, and dynamic indication.

[0395] For resource indication type 0, the length of the FDRA field is N RBG The bits are used to indicate frequency domain resources in the form of a bitmap. The interpretation of the frequency domain indication depends on the CFR bandwidth, the starting PRB position, and the configuration parameters of the higher layer.

[0396] For resource indication type 1, the length of the FDRA field is The frequency domain indication is performed in the form of RIV. The interpretation of the frequency domain indication depends on the bandwidth of CFR and the starting PRB position. (Similar to the above RIV definition, but using replace RB start It is defined with the lowest PRB of CFR as the reference point)

[0397] For dynamic indications, the FDRA field length is When the most significant bit (MSB) is 0, it is used to indicate resource indication type 0; when the MSB is 1, it is used to indicate resource indication type 1.

[0398] When the CFR lengths of the Redcap UE receiving multicast services are different from those of the Normal UE but some or all of the frequency domain resources overlap, the network device cannot simultaneously schedule the Redcap UE CFR and the Normal UE CFR to receive multicast services at the same frequency domain resource location through a DCI format 4_1 / DCI format 4_2 due to the different FDRA field lengths.

[0399] It can be seen that when the CFR configured by the network device for the Redcap UE is different from the CFR configured for the Normal UE, it is difficult for the network device to use one downlink control information, such as DCI format 4_0 / DCI format 4_1 / DCI format 4_2, to simultaneously schedule the Redcap UE and the Normal UE to receive broadcast services / multicast services.

[0400] In view of this, the present disclosure provides a method for interpreting frequency domain resource indications for Redcap UEs, enabling Redcap UEs to decode downlink control information indicating Normal UEs, thereby correctly receiving broadcast or multicast services. The resource determination method, resource configuration method, terminal, and network device provided in the present disclosure are described below with reference to the accompanying drawings.

[0401] Please refer to Figure 4, which is a flow chart of a resource determination method provided by an embodiment of the present disclosure. As shown in Figure 4, the resource determination method includes the following steps:

[0402] Step 401: A first terminal determines first frequency domain information and second frequency domain information, where the first frequency domain information is actual frequency domain resource information configured by a network device, and the second frequency domain information is reference frequency domain resource information configured by the network device.

[0403] Step 402: The first terminal determines the frequency domain resources indicated by the first domain of the received first DCI according to the second frequency domain information or the first frequency domain information, where the first domain is the FDRA domain.

[0404] In step 402, the process of the first terminal determining the frequency domain resources indicated by the first domain based on the second frequency domain information or the first frequency domain information can be understood as the process of the first terminal using the second frequency domain information or the first frequency domain information to interpret (or parse) the first domain. The first terminal can determine the frequency domain resources indicated by the first domain by interpreting the first domain. Here, the frequency domain resources indicated by the first domain can be understood as the frequency domain resources for receiving broadcast or multicast services. Therefore, the terminal needs to determine the frequency domain resources indicated by the first domain in order to correctly receive broadcast or multicast services.

[0405] In an embodiment of the present disclosure, the first terminal determines the first frequency domain information and / or the second frequency domain information, where the first frequency domain information is the actual frequency domain resource information configured by the network device, and the second frequency domain information is the reference frequency domain resource information configured by the network device; the first terminal determines the frequency domain resources indicated by the first domain of the first DCI based on the second frequency domain information or the first frequency domain information, where the first domain is the FDRA domain. Through the above process, since the network device configures the actual frequency domain resource information and the reference frequency domain resource information for the first terminal, when the frequency domain resources configured for the first terminal are different from those of other terminals, if the network device uses the same scheduling signaling to schedule the first terminal and other terminals at the same time, the first terminal can correctly interpret the frequency domain resources indicated by the FDRA domain based on the reference frequency domain resource information. This enables terminals with different frequency domain resource configurations to be scheduled by the same scheduling signaling, thereby saving signaling overhead.

[0406] In the disclosed embodiments, the first DCI may be DCI for scheduling a terminal to receive MBS. The second frequency domain information may be information related to the actual frequency domain resources of the second terminal. The CFR configured for the first terminal partially overlaps with the CFR configured for the second terminal. For example, the first terminal may be a Redcap UE and the second terminal may be a Normal UE. In this way, the network device can simultaneously schedule Redcap UEs and Normal UEs to receive multicast / broadcast services using the same scheduling signaling.

[0407] In some embodiments, the first terminal determines, according to the second frequency domain information, the frequency domain resources indicated by the first field of the first DCI, including:

[0408] The first terminal determines the frequency domain resource length indicated by the first domain and the frequency domain resource starting position indicated by the first domain based on the reference frequency domain length and the reference frequency domain starting position included in the second frequency domain information; or determines the available frequency domain resource position indicated by the first domain, and the first domain uses a bit map to indicate the available frequency domain resource position.

[0409] It should be noted that the indication method of the first domain includes two indication methods: RIV and bitmap. Among them, determining the frequency domain resource length indicated by the first domain and the starting position of the frequency domain resources indicated by the first domain corresponds to the RIV indication method; and determining the available frequency domain resource position indicated by the first domain corresponds to the bitmap indication method.

[0410] In some embodiments, the first terminal determines, based on the reference frequency domain length and the reference frequency domain starting position, a frequency domain resource length indicated by the first domain and a frequency domain resource starting position indicated by the first domain, including:

[0411] The first terminal calculates, according to a resource indicator value (RIV) in the first domain and a preconfigured frequency domain resource length, a first frequency domain resource length and a starting position of the first frequency domain resource;

[0412] Determining, by the first terminal, a scaling factor according to a size relationship between the preconfigured frequency domain resource length and the reference frequency domain length;

[0413] The first terminal determines the frequency domain resource length indicated by the first domain based on the scaling factor and the first frequency domain resource length, and determines the frequency domain resource starting position indicated by the first domain based on the scaling factor and the first frequency domain resource starting position.

[0414] The preconfigured resource length may be, for example, the resource length N of the starting BWP / CORESET. initial (You can also use The first length can be represented by L′ RBs Indicates that the first starting position can be represented by RB′ start The scaling factor can be represented by K. As an example, the frequency domain resource length indicated by the first domain can be equal to the product of the scaling factor and the first length, that is, L RB =K×L′ RBs The frequency domain resource starting position indicated by the first domain may be equal to the product of the scaling factor and the first starting position, ie, RB Start =K×RB′ start The starting position of the frequency domain resource may be the frequency domain resource starting PRB.

[0415] In some embodiments, the first terminal determines the scaling factor according to a size relationship between the preconfigured resource length and the reference frequency domain length, including:

[0416] exist In the case of

[0417] exist In the case of , K = 1;

[0418] in, Represents the reference frequency domain length, N initial represents the preconfigured resource length, and K represents the scaling factor.

[0419] In some embodiments, the method further comprises:

[0420] The first terminal determines the bit length of the first domain according to the second frequency domain information.

[0421] In this embodiment, the second frequency domain information can be used to determine not only the frequency domain resource length indicated by the first domain, but also the bit length of the first domain. Specifically, the first terminal can first determine the bit length of the first domain based on the second frequency domain information, and then determine the frequency domain resource length indicated by the first domain based on the second frequency domain information.

[0422] As previously mentioned, the FDRA field of DCI format 4_2 is divided into three types: resource indication type 0, resource indication type 1, and dynamic indication. The length of the FDRA field in different types may vary. Therefore, when the first DCI is DCI format 4_2, the first terminal can determine the length of the first field based on the second frequency domain information.

[0423] In some embodiments, the second frequency domain information includes a reference frequency domain length;

[0424] The first terminal determines, according to the second frequency domain information, a length of the first domain, including at least one of the following:

[0425] When the resource indication type of the first field is resource indication type 0, the length of the first field determined by the first terminal is M bits, where M is obtained according to the reference frequency domain length included in the second frequency domain information;

[0426] In the case where the resource indication type of the first field is resource indication type 1, the first terminal determines that the length of the first field is Bit;

[0427] In the case where the resource indication type of the first field is a dynamic indication type, the first terminal determines that the length of the first field is Bit;

[0428] in, Indicates the reference frequency domain length.

[0429] In some embodiments, the first terminal determines the first frequency domain information and / or the second frequency domain information, including:

[0430] The first terminal determines the first frequency domain information and the second frequency domain information according to the received first configuration parameter and second configuration parameter of the network device;

[0440] A second RIV for determining the second frequency domain information;

[0441] length information corresponding to the second frequency domain information;

[0442] The starting position information corresponding to the second frequency domain information.

[0443] Example 1: The network device configures the RIV values ​​corresponding to the reference frequency range and the actual frequency range respectively. That is, the first configuration parameter is the RIV value corresponding to the reference frequency range, and the second configuration parameter is the RIV value corresponding to the actual frequency range.

[0444] Example 2: The reference frequency domain range and the actual frequency domain range share the same starting PRB information. The network device configures the RIV value for the reference frequency domain range and the length information for the actual frequency domain range. Specifically, the first configuration parameter is the RIV value corresponding to the reference frequency domain range, and the second configuration parameter is the length information for the actual frequency domain range.

[0445] Example 3: The reference frequency domain range and the actual frequency domain range share the same starting PRB information. The network device configures the RIV value of the actual frequency domain range and the length information of the reference frequency domain range. Specifically, the first configuration parameter is the length information of the reference frequency domain range, and the second configuration parameter is the RIV value of the actual frequency domain range.

[0446] Example 4: The reference frequency domain range and the actual frequency domain range share end PRB information. The network device configures the RIV value for the reference frequency domain range and the starting position information for the actual frequency domain range. Specifically, the first configuration parameter is the RIV value corresponding to the reference frequency domain range, and the second configuration parameter is the starting position information for the actual frequency domain range.

[0447] Example 5: The reference frequency domain range and the actual frequency domain range share end PRB information. The network device configures the RIV value of the actual frequency domain range and the starting position information of the reference frequency domain range. Specifically, the first configuration parameter is the starting position information of the reference frequency domain range, and the second configuration parameter is the RIV value of the actual frequency domain range.

[0448] In the disclosed embodiments, two methods for interpreting the first domain can be defined: a first interpretation method and a second interpretation method. The first interpretation method refers to a method in which a terminal interprets the first domain based on a reference frequency domain range, while the second interpretation method refers to a method in which a terminal interprets the first domain based on an actual frequency domain range. The following describes implementations related to the interpretation methods.

[0449] In some embodiments, the first terminal determines, according to the second frequency domain information or the first frequency domain information, the frequency domain resources indicated by the first domain in the first DCI, including:

[0450] When the first terminal determines to use the first interpretation method to interpret the first domain, the first terminal determines the frequency domain resources indicated by the first domain according to the second frequency domain information;

[0451] The first interpretation method is to interpret the first domain using the second frequency domain information.

[0452] In some embodiments, the first terminal determines, according to the second frequency domain information or the first frequency domain information, the frequency domain resources indicated by the first domain, including:

[0453] When the first terminal determines not to use the first interpretation method to interpret the first domain, the first terminal determines the frequency domain resources indicated by the first domain according to the first frequency domain information.

[0454] Here, when it is determined not to adopt the first interpretation method, the first terminal may adopt the second interpretation method to interpret the first domain, that is, the first terminal interprets the first domain according to the actual frequency domain range.

[0455] In some embodiments, the method further comprises:

[0456] The first terminal determines, based on a preconfigured first association relationship, whether to use the first interpretation method to interpret the first domain, where the first association relationship is used to determine the interpretation method of the first domain;

[0457] or;

[0458] Determining, by the first terminal, whether to use the first interpretation method to interpret the first domain according to the received third configuration parameter of the network device;

[0459] or,

[0460] The first terminal determines, based on the second field of the first DCI, whether to use the first interpretation method to interpret the first field.

[0461] This embodiment provides the above three parallel schemes to determine the interpretation method of the first domain. When the high layer pre-configured with a first association relationship, the first terminal can determine whether to use the first interpretation method to interpret the first domain based on the first association relationship. When the network device sends a configuration parameter to indicate the interpretation method of the first domain, the first terminal can determine whether to use the first interpretation method to interpret the first domain based on the third configuration parameter sent by the network device. The third configuration parameter can be carried by system information (such as SIB 20) or UE-specific information (UE-specific) (such as CFR-ConfigMulticast). The first terminal can also determine whether to use the first interpretation method to interpret the first domain based on the second domain of the first DCI. The second domain can be understood as a domain used to explicitly or implicitly indicate the interpretation method of the first domain. The second domain can be a domain dedicated to indicating the interpretation method of the first domain, or it can be a domain that other DCI domains are multiplexed to indicate the interpretation method of the first domain. This embodiment of the present disclosure is not limited to this.

[0462] In some embodiments, the first terminal determines, based on the second field of the first DCI, whether to interpret the first field using the first interpretation method, including:

[0463] Determining, according to the received high-layer signaling, that the second field of the first DCI is used to indicate an interpretation method of the first field;

[0464] According to the second domain, it is determined whether to use the first interpretation method to interpret the first domain.

[0465] In this implementation, a higher layer may introduce a parameter (which may be referred to as a fourth configuration parameter) to configure whether the second field of the first DCI is used to indicate the interpretation method of the first field.

[0466] In some embodiments, the first association relationship includes at least one of the following:

[0467] a correlation between the search space and the interpretation of the first domain;

[0468] An association relationship between a Group Radio Network Temporary Identifier (G-RNTI) and a method for interpreting the first domain.

[0469] In some embodiments, the method further comprises at least one of the following:

[0470] The first terminal determines, according to a search space corresponding to a blind monitoring occasion (Mornitoring Occasion, MO), whether to use the first interpretation method to interpret the first domain;

[0471] The first terminal determines, according to the G-RNTI of the first DCI, whether to use the first interpretation method to interpret the first domain.

[0472] In some embodiments, the second field is an interpretation mode indication field, and the second field is located after the existing DCI field.

[0473] Specifically, an FDRA field interpretation mode indicator field can be introduced into DCI format 4_0 / 4_1 / 4_2, and this indicator field is placed after the last DCI field of the existing DCI field. This indicator field can be configured to be parsed only by Redcap UEs and not by Normal UEs.

[0474] In some embodiments, the second field is located after the third field of the first DCI;

[0475] The first DCI is DCI format 4_0, and the third field is an MCCH change notification field (i.e., an "MCCH change notification" field); or,

[0476] The first DCI is DCI format 4_1, and the third field is a PDSCH to hybrid automatic repeat request (HARQ) feedback timing indicator field (i.e., a "PDSCH-to-HARQ_feedback timing indicator" field); or,

[0477] The first DCI is DCI format 4_2, and the third field is a demodulation reference signal (DMRS) sequence initialization field (ie, a "DMRS sequence initialization" field).

[0478] In some embodiments, the second field is a virtual resource block (VRB)-PRB mapping field.

[0479] In some embodiments, if the second field indicates non-interleaved correspondence, the first terminal determines to use the first interpretation method to interpret the first field; if the second field indicates interleaved correspondence, the first terminal determines not to use the first interpretation method to interpret the first field.

[0480] In some embodiments, the method further comprises:

[0481] The first terminal determines whether to receive the broadcast service scheduled by the first DCI according to the first frequency domain information and the frequency domain resources indicated by the first domain.

[0482] That is, for the broadcast service, the first terminal may determine whether it is capable of receiving the broadcast service indicated by the downlink control information based on the PRB range parsed from the FDRA domain and the CFR capability range for receiving the broadcast service.

[0483] In some embodiments, the first terminal determines, based on the first frequency domain information and the frequency domain resources indicated by the first domain, whether to receive the broadcast service scheduled by the first DCI, including:

[0484] When the PRB range indicated by the first domain is within the physical resource block PRB range corresponding to the first frequency domain information, the first terminal determines to receive the broadcast service scheduled by the first DCI;

[0485] When the PRB range indicated by the first domain is not within the physical resource block PRB range corresponding to the first frequency domain information, the first terminal determines to discard the broadcast service scheduled by the first DCI.

[0486] In this implementation, the first terminal compares the parsed PRB range with the PRB range supported by the first terminal. If the parsed PRB range is completely within the range supported by the terminal capability, the first terminal receives the broadcast service; otherwise, the first terminal discards the broadcast service and does not need to receive broadcast data information.

[0487] In some embodiments, the first terminal determines, based on the first frequency domain information and the frequency domain resources indicated by the first domain, whether to receive the broadcast service scheduled by the first DCI, including:

[0488] When the RIV corresponding to the PRB range indicated by the first field is less than or equal to the RIV maximum threshold, the first terminal determines to receive the broadcast service scheduled by the first DCI;

[0489] When the RIV corresponding to the PRB range indicated by the first domain is greater than the RIV maximum threshold, the first terminal determines to discard the broadcast service scheduled by the first DCI;

[0490] in, RIV MAX represents the RIV maximum threshold, Represents the common frequency domain resource part CFR range of the first terminal.

[0491] In this embodiment, the first terminal calculates the RIV based on the parsed PRB range and the CFR range of the first terminal. If the calculated RIV is less than or equal to The first terminal receives the broadcast service; otherwise, the first terminal discards the broadcast service and does not need to receive the broadcast data information.

[0492] In some embodiments, the method further comprises:

[0493] When the first terminal determines to discard the broadcast service scheduled by the first DCI and the first terminal is interested in the broadcast service scheduled by the first DCI, the first terminal reports second information to the network side device after entering the radio resource control (RRC) connection state, and the second information is used to indicate that the frequency domain resources indicated by the first domain are not within the capability support range of the first terminal.

[0494] In this implementation, if the first terminal is interested in the broadcast service but cannot receive the broadcast service because the indicated PRB exceeds the terminal capability, the first terminal may report the event to the network after entering the RRC connected state.

[0495] The embodiments of the present disclosure can be applied to 5G NR systems as well as other systems. In the embodiments of the present disclosure, a network device can schedule terminals with two frequency domain resource configurations to receive the same data using the same downlink control information.

[0496] Figures 5 and 6 are schematic diagrams of applicable scenarios of the embodiments of the present disclosure. When the CFR configurations of the Redcap UE and the Normal UE are different and some frequency domain resources overlap, the network device instructs the Redcap UE and the Normal UE to receive data information of the broadcast / multicast service through a downlink control message.

[0497] In order to better understand the technical solutions of the embodiments of the present disclosure, specific embodiments are provided below for illustrative purposes.

[0498] Example 1:

[0499] This embodiment is used to introduce a feasible solution for interpreting the FDRA field when a type 1 terminal receives downlink control information (such as DCI format 4_0) for scheduling broadcast services. This embodiment may include the following steps:

[0500] Step 1a: The network device configures relevant parameters of the reference frequency domain range and the actual frequency domain range through system information.

[0501] Step 1b: The type 1 terminal obtains the reference frequency domain range and the actual frequency domain range, which may include the following methods:

[0502] (1) Type 1 terminals obtain the reference frequency domain range, including the reference frequency domain starting position information and reference frequency domain length information, through the RIV value in the "cfr-ConfigMCCH-MTCH-r17" parameter in the system information. Type 1 terminals obtain the actual frequency domain range, including the actual frequency domain starting position information and actual frequency domain length information, through the RIV value in the "cfr-ConfigMCCH-MTCH-redcap" parameter in the system information.

[0503] (2) Type 1 terminals obtain the reference frequency domain range, including the reference frequency domain starting position information and reference frequency domain length information, through the RIV value in the "cfr-ConfigMCCH-MTCH-r17" parameter in the system information. Type 1 terminals obtain the starting PRB information of the actual frequency domain range through the starting PRB information corresponding to the RIV value in the "cfr-ConfigMCCH-MTCH-r17" parameter in the system information, and then obtain the length information of the actual frequency domain range through the "cfr-ConfigMCCH-MTCH-Length-redcap" parameter in the system information.

[0504] (3) Type 1 terminals obtain the reference frequency domain range, including the reference frequency domain starting position information and reference frequency domain length information, through the RIV value in the "cfr-ConfigMCCH-MTCH-r17" parameter in the system information. Type 1 terminals obtain the ending PRB information of the actual frequency domain range through the length information corresponding to the RIV value in the "cfr-ConfigMCCH-MTCH-r17" parameter in the system information (obtaining the ending PRB information through S+L), and then obtain the starting PRB information of the actual frequency domain range through the "cfr-ConfigMCCH-MTCH-Start-redcap" parameter in the system information.

[0505] Step 1c: The network device sends downlink control information, such as DCI format 4_0, to the type 1 terminal for scheduling data information of the broadcast service.

[0506] Step 1d: Type 1 terminal receives the DCI sent by the network device and calculates the DCI based on the reference frequency domain range length. and the reference frequency domain range starting PRB Interpret the FDRA field in DCI format 4_0. The specific method is as follows:

[0507] (1d-1) Type 1 terminal parses the RIV value in the FDRA field and uses the resource length of the starting BWP / CORESET and RIV definition, calculate L′ RBs and RB′ start .

[0508] (1d-2) Type 1 terminal based on the resource length of the starting BWP / CORESET and reference resource length The relationship between and determines the value of the scaling factor K. but Otherwise, K=1.

[0509] (1d-3) Type 1 terminal according to formula L RB =K×L′ RBs Calculate the frequency domain resource length indicated by the FDRA field (i.e., L RB ).

[0510] (1d-4) Type 1 terminal according to the formula RB Start =K×RB′ start Calculate the frequency domain resource starting PRB indicated by the FDRA field (ie RB Start ), here, RB Start by As the starting PRB reference point.

[0511] Step 1e: Type 1 terminal determines whether it is capable of receiving the broadcast service indicated by this downlink control information based on the PRB range parsed from the FDRA field and the CFR range of the actual broadcast service received. The actual frequency domain starting position is The specific method is as follows:

[0512] (1e-1) If the frequency domain resource location indicated by the FDRA field is completely within the first CFR range, the terminal can accept the broadcast service indicated by this downlink control information. The judgment condition can be, for example:

[0513] satisfy and or,

[0514] RB′ Start and L RB Calculate RIV according to the first CFR range, and the calculated RIV is less than

[0515] Among them, RB Start and L RB This parameter is the value parsed from the FDRA domain. Other parameters are values ​​obtained from high-level configuration.

[0516] (1e-2) Otherwise, the terminal discards the broadcast service indicated by this downlink control information.

[0517] If a Type 1 terminal is interested in a broadcast service but cannot receive it because the indicated PRB exceeds the terminal's capabilities, the Type 1 terminal may report this event to the network device after entering the RRC connected state. The reported information may include the broadcast G-RNTI and / or the Type 1 terminal's receiving capabilities.

[0518] This embodiment provides a solution for Type 1 terminals to parse the FDRA field using a reference CFR range, and for Type 1 terminals to determine whether they are capable of receiving the broadcast service indicated by this downlink control information. In this embodiment, the network device does not know whether any Type 1 terminals are among the receiving terminals when sending a broadcast message, and cannot guarantee that all broadcast schedules will meet the broadcast service reception capabilities of Type 1 terminals. Therefore, Type 1 terminals need to parse the broadcast control signaling to determine whether they are capable of receiving the data information of this broadcast service and subsequently report the trigger event.

[0519] Example 2:

[0520] This embodiment introduces a feasible solution for interpreting the FDRA field when a Type 1 terminal receives downlink control information (e.g., DCI format 4_1) for scheduling multicast services. Compared with Example 1, the main difference is that the network device directly configures the reference CFR range for the Type 1 terminal through UE-specific RRC signaling. The specific configuration concept is similar to that of (1) to (3) in Example 1.

[0521] Since the network device directly configures the reference CFR range for the type 1 terminal through UE-specific RRC signaling, this embodiment does not involve step 1e in embodiment 1. The remaining steps are similar to the concept of embodiment 1. Specifically, this embodiment may include the following steps:

[0522] Step 2a: The network device configures relevant parameters of the reference frequency domain range and the actual frequency domain range through UE-specific RRC signaling.

[0523] For example, the network device configures the CFR range (i.e., the actual CFR range) for receiving multicast services for the type 1 terminal through the "locationAndBandwidthMulticast-r17" parameter in the UE-specific RRC signaling, which is defined as the first CFR range. The type 1 terminal needs to receive the configuration information of the first CFR range and interpret it to obtain the resource length of the first CFR range. and resource starting location

[0524] The network device configures a second CFR range (i.e., a reference CFR range) for a type-one terminal through the "locationAndBandwidthMulticast-r19-Reference" parameter in the UE-specific RRC signaling. The second CFR range can be the CFR range of a type-two terminal receiving multicast services. The type-one terminal needs to receive the configuration information of the second CFR range and interpret it to obtain the reference resource length. and reference resource starting location

[0525] Step 2b: The type 1 terminal obtains a reference frequency domain range and an actual frequency domain range.

[0526] Step 2c: The network device sends downlink control information, such as DCI format 4_1, to the type 1 terminal for scheduling data information of the multicast service.

[0527] Step 2d: Type 1 terminal receives the DCI sent by the network device and and Decode the FDRA field in DCI format 4_1. The specific method is as follows:

[0528] (2d-1) Type 1 terminal parses the RIV value in the FDRA field and uses the resource length of the starting BWP / CORESET and RIV definition, calculate L′ RBs and RB′ start .

[0529] (2d-2) Type 1 terminal based on the resource length of the starting BWP / CORESET and reference resource length The relationship between and determines the value of the scaling factor K. but Otherwise, K=1.

[0530] (2d-3) Type 1 terminal according to formula L RB =K×L′ RBs Calculate the frequency domain resource length indicated by the FDRA field (i.e., L RB ).

[0531] (2d-4) Type 1 terminal according to the formula RB Start =K×RB′ start Calculate the frequency domain resource starting PRB indicated by the FDRA field (ie RB Start ), here, RB Start by As the starting PRB reference point.

[0532] This embodiment provides a solution in which a network device directly configures a reference CFR range for a type-1 terminal, and the type-1 terminal uses the reference CFR range to parse the FDRA field.

[0533] Example 3:

[0534] This embodiment introduces a feasible solution for interpreting the FDRA field when a Type 1 terminal receives downlink control information (e.g., DCI format 4_2) for scheduling multicast services. Compared with Embodiment 2, the main difference is that the FDRA field length needs to be determined based on the reference CFR length.

[0535] Step 3a: the same as step 2a of Example 2;

[0536] Step 3b: the same as step 2b of Example 2;

[0537] Step 3c: The network device sends downlink control information, such as DCI format 4_2, to the type 1 terminal for scheduling data information of the multicast service.

[0538] Step 3d: The type 1 terminal receives the DCI sent by the network device and uses the reference resource length and reference resource starting location Interpret the FDRA field in DCI format 4_2. The specific method is as follows:

[0539] Resource allocation type 0: Type 1 terminal based on and the high-level RBG size configuration parameter (rbg-Size) to determine the RBG size P, and then according to Determine the number of RBGs

[0540] Resource allocation type 1: Type 1 terminal parses the RIV value in the FDRA field and and RIV definition to obtain LRB and RB Start , and is based on As the starting PRB reference point.

[0541] Type 1 terminals determine the FDRA field length in the following ways:

[0542] If the resource allocation type is 0, the length of the FDRA field is bit;

[0543] If resource allocation type 1 is configured, the length of the FDRA field is

[0544] If dynamic resource allocation is configured, the length of the FDRA field is

[0545] This embodiment provides a method for a type 1 terminal to determine the length of a reference resource. A scheme for determining the length of the FDRA field in DCI format 4_2.

[0546] Example 4:

[0547] This embodiment is used to introduce a feasible solution in which a type one terminal determines whether to use the first interpretation method to interpret the FDRA field according to an instruction of a physical layer signaling or a configuration of a higher layer signaling.

[0548] Solution 1: Introduce an "FDRA field interpretation mode" indicator field (i.e., the second field) in DCI format 4_0 / 4_1 / 4_2. This indicator field is placed after the last DCI field in the existing DCI field and can only be parsed by type 1 terminals but not type 2 terminals.

[0549] For example, a DCI field is added after the "MCCH change notification" field in DCI format 4_0 to indicate the FDRA field interpretation method. The length of this field can be 1 bit, for example, "1" indicates the first interpretation method, and "0" indicates the second interpretation method.

[0550] A DCI field is added after the "PDSCH-to-HARQ_feedback timing indicator" field in DCI format 4_1 to indicate the FDRA field interpretation method. This field can be 1 bit long, for example, "1" indicates the first interpretation method and "0" indicates the second interpretation method.

[0551] A DCI field is added after all configuration DCI fields or the "DMRS sequence initialization" field in DCI format 4_2 to indicate the FDRA field interpretation method. The presence of this field in DCI format 4_2 can be determined based on higher-layer parameters. The length of this field can be 1 bit. For example, "1" indicates the first interpretation method, and "0" indicates the second interpretation method. Furthermore, the length of DCI format 4_2 received by Type 1 and Type 2 terminals should be the same.

[0552] When a Type 1 terminal receives a DCI format 4_0 / 4_1 / 4_2 containing the "FDRA field interpretation mode" indicator field, it needs to parse the "FDRA field interpretation mode" indicator field. If this field indicates the use of the first interpretation mode, the Type 1 terminal parses the FDRA field content according to the reference CFR range; if this field indicates the use of the second interpretation mode, the Type 1 terminal parses the FDRA field content according to the actual CFR range.

[0553] When a type 2 terminal receives DCI format 4_0 / 4_1 / 4_2 containing the "FDRA field interpretation method" indication field, it does not need to parse the "FDRA field interpretation method" indication field and parses the FDRA field content in the existing method.

[0554] A higher-layer parameter (i.e., the first parameter) can be introduced at the higher layer as a switch indication of whether the "FDRA domain interpretation mode" indication field can be used to indicate the FDRA domain interpretation mode. The scope of this higher-layer parameter may be a certain G-RNTI, a certain DCI format, or a certain carrier. When the higher layer configures this parameter, the "FDRA domain interpretation mode" indication field can be used to indicate the FDRA domain interpretation mode; if it is in the default state, the "FDRA domain interpretation mode" indication field cannot be used to indicate the FDRA domain interpretation mode.

[0555] Solution 2: The FDRA field interpretation method is implicitly indicated according to the "VRB-to-PRB mapping" field in DCI format 4_0 / 4_1 / 4_2. If non-interleaved mapping is indicated, the first interpretation method is adopted; otherwise, the second interpretation method is adopted.

[0556] For Type 1 terminals, the "VRB-to-PRB mapping" field in DCI format 4_0 / 4_1 / 4_2 implicitly indicates the FDRA field interpretation method. When this field indicates non-interleaved, it indicates the first interpretation method; when this field indicates interleaved, it indicates the second interpretation method.

[0557] A higher-layer parameter (i.e., the second parameter) can be introduced at the higher layer as a switch indication of whether the "VRB-to-PRB mapping" field can be used to indicate the FDRA field interpretation method, such as ReusevrbtoprbmappingEnabling-redcap. The scope of this higher-layer parameter may be a certain G-RNTI, or a certain DCI format, or a certain carrier. When the higher layer configures this parameter, the "VRB-to-PRB mapping" field can be used to indicate the FDRA field interpretation method; if it is in the default state, the "VRB-to-PRB mapping" field cannot be used to indicate the FDRA field interpretation method.

[0558] Solution 3: Introduce an FDRA field interpretation configuration parameter (e.g., Fdratype-redcap) in system information (e.g., SIB 20) to indicate the FDRA field interpretation method for DCI format 4_0 / 4_1 / 4_2. For Type 1 terminals, if the upper layer configures this parameter or indicates the first interpretation method, the terminal interprets the FDRA field using the first interpretation method. If the upper layer does not configure this parameter or indicates the second interpretation method, the terminal interprets the FDRA field using the second interpretation method.

[0559] Solution 4: Introduce a reference frequency domain range indication configuration parameter (for example, locationAndBandwidthMulticast-r19-Reference or Fdratype-redcap) in UE-specific information (such as CFR-ConfigMulticast) to indicate which interpretation method is used for DCI format 4_1 / 4_2 to interpret the FDRA field. For type 1 terminals, if the upper layer configures this parameter or indicates the first interpretation method, the type 1 terminal uses the first interpretation method to interpret the FDRA field; if the upper layer does not configure this parameter or indicates the second interpretation method, the type 1 terminal uses the second interpretation method to interpret the FDRA field.

[0560] Solution 5: Associate the search space with the FDRA field interpretation method. Type 1 terminals determine which interpretation method to use based on the search space corresponding to the MO for blind monitoring. For example, associate the MO corresponding to the search space with the FDRA field interpretation method through high-layer parameters. When a Type 1 terminal blindly monitors and detects DCI format 4_0 / 4_1 / 4_2, if the MO is associated with the first interpretation method, the Type 1 terminal interprets the FDRA field using the first interpretation method; otherwise, the Type 1 terminal interprets the FDRA field using the second interpretation method.

[0561] Solution 6: Associate the G-RNTI with the FDRA field interpretation method. Type 1 terminals determine which interpretation method to use based on the G-RNTI used to parse the downlink control information. For example, the G-RNTI and FDRA field interpretation method are associated through high-layer parameters. If a Type 1 terminal detects that the G-RNTI in DCI format 4_0 / 4_1 / 4_2 is associated with the first interpretation method, the Type 1 terminal interprets the FDRA field using the first interpretation method; otherwise, the Type 1 terminal interprets the FDRA field using the second interpretation method.

[0562] The above methods can be applied independently to DCI format 4_0 / 4_1 / 4_2, or in combination. For example, DCI format 4_0 adopts solution 1, DCI format 4_1 adopts solution 2, and DCI format 4_2 adopts solution 3. This embodiment focuses on describing the implementation schemes without limiting any combination.
