[0373] Among them, the terminal 11 involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to the user, a handheld device with a wireless connection function, 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 a user equipment (UE). A wireless terminal can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal.

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 arranged geographically separately.

[0375] In the embodiment of the present application, the network device and the terminal can each use one or more antennas for multiple input multiple output (MIMO) transmission, and the MIMO transmission can be single user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). According to the form and number of antenna combinations, MIMO transmission can be two-dimensional MIMO (2D-MIMO), three-dimensional MIMO (3D-MIMO), full-dimensional MIMO (FD-MIMO) or massive MIMO, and can also be diversity transmission, precoded transmission, beamforming transmission, etc.

[0376] Before describing the embodiments of the present application, the following briefly introduces the related technologies:

[0377] Based on NR broadcast services, network devices can send physical downlink control channels (PDCCH) and physical downlink shared channels (PDSCH) for broadcast services within CFR. CFR can be independently configured through the "cfr-Config MCCH-MTCH" parameter in System Information Block 20 (SIB20), and its bandwidth can be equal to or greater than the bandwidth of the initial bandwidth part (Bandwidth Part, BWP).

[0378] 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).

[0379] Based on the above background, the CFR configurations for Redcap UEs and Normal UEs include the following two cases:

[0380] Case 1: Redcap UE CFR = Normal UE CFR (as Figure 2 shown);

[0381] Case 2: Redcap UE CFR < Normal UE CFR (as Figure 3 shown).

[0382] 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).

[0383] For Case 2, since the bandwidths and the starting PRBs of the Redcap UE CFR and the Normal UE CFR are different, even if the Redcap UE CFR is within the PRB range of the Normal UE CFR, as 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 as follows:

[0384] (1) Analysis from the perspective of DCI format 4_0:

[0385] 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 means of a resource indicator value (RIV), which is defined as follows:

[0386] if but

[0387] otherwise

[0388] When L' RBs =L RBs K, RB' start =RB start K and when L' RBs Will not exceed

[0389] 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 the starting position of the frequency domain resource RB start The scaling factor K is determined by the following formula: CFR satisfy but Otherwise, K = 1. start It is determined by taking the lowest resource block (RB) of the CFR as a reference physical resource block (PRB).

[0390] When Redcap UE CFR is configured independently, it calculates K and RB startIt may be different from the value of Normal UE. This will cause the frequency domain resource location information decoded by Redcap UE to be different from the frequency domain resource location information decoded by Normal UE when reading the RIV indication in the FDRA field. Therefore, the network device cannot schedule Redcap UE CFR and Normal UE CFR to receive broadcast services at the same frequency domain resource location through a DCIformat 4_0.

[0391] (2) Multicast Service

[0392] The network device schedules a group of terminals to receive multicast services through DCI format 4_1 or DCI format 4_2. The FDRA field length and indication mode of DCI format 4_1 are the same as those of DCI format 4_0. The FDRA field of DCI format 4_2 is divided into three modes: resource indication type 0, resource indication type 1, and dynamic indication.

[0393] For resource indication type 0, the length of the FDRA field is N RBG Bits are used to indicate frequency domain resources in the form of a bitmap. The interpretation of the frequency domain indication depends on the bandwidth of the CFR, the starting PRB position, and the configuration parameters of the higher layer.

[0394] For resource indication type 1, the length of the FDRA field is The frequency domain indication is performed in the form of RIV, and the interpretation of the frequency domain indication depends on the bandwidth of the 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)

[0395] For dynamic indications, the length of the FDRA field 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.

[0396] When the CFR lengths of the Redcap UE receiving multicast services are different from those of the Normal UE receiving multicast services but some or all of the frequency domain resources overlap, due to the different FDRA field lengths, 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 one DCIformat 4_1 / DCI format 4_2.

[0397] 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 format4_1 / DCI format 4_2, to simultaneously schedule the Redcap UE and the Normal UE to receive broadcast services / multicast services.

[0398] In view of this, the embodiment of the present application proposes a frequency domain resource indication interpretation method for Redcap UE, so that the Redcap UE can decode the downlink control information used to indicate the Normal UE, thereby correctly receiving the broadcast or multicast service. The resource determination method, resource configuration method, terminal and network device provided in the embodiment of the present application are described below in conjunction with the accompanying drawings.

[0399] See also Figure 4 , Figure 4 is a flow chart of a resource determination method provided by an embodiment of the present application. Figure 4 As shown, the resource determination method includes the following steps:

[0400] Step 401: The 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;

[0401] 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.

[0402] In step 402, the process in which the first terminal determines the frequency domain resources indicated by the first domain according to the second frequency domain information or the first frequency domain information can be understood as the process in which the first terminal uses the second frequency domain information or the first frequency domain information to interpret (or parse) the first domain, and 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 so as to correctly receive the broadcast or multicast service.

[0403] In an embodiment of the present application, the first terminal determines the first frequency domain information and / or the second frequency domain information, 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, and 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 by the first terminal are different from those of other terminals, if the network device schedules the first terminal and other terminals at the same time with the same scheduling signaling, 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.

[0404] In the embodiment of the present application, the first DCI may be a 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 may schedule the Redcap UE and the Normal UE to receive multicast / broadcast services at the same time through the same scheduling signaling.

[0405] In some embodiments, the first terminal determines, according to the second frequency domain information, the frequency domain resources indicated by the first domain of the first DCI, including:

[0406] 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.

[0407] It should be noted that the indication method of the first domain includes two indication methods, RIV and bitmap. Among them, determining the length of the frequency domain resources 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 position of the available frequency domain resources indicated by the first domain corresponds to the bitmap indication method.

[0408] In some embodiments, the first terminal determines, according to 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:

[0409] The first terminal calculates a first frequency domain resource length and a first frequency domain resource starting position according to a resource indicator value (RIV) in the first domain and a preconfigured frequency domain resource length;

[0410] The first terminal determines a scaling factor according to a size relationship between the preconfigured frequency domain resource length and the reference frequency domain length;

[0411] The first terminal determines the frequency domain resource length indicated by the first domain according to the scaling factor and the first frequency domain resource length, and determines the frequency domain resource starting position indicated by the first domain according to the scaling factor and the first frequency domain resource starting position.

[0412] 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 starting PRB of the frequency domain resource.

[0413] Optionally, the first terminal determines the scaling factor according to a size relationship between the preconfigured resource length and the reference frequency domain length, including:

[0414] exist In the case of

[0415] exist In the case of , K = 1;

[0416] in, represents the reference frequency domain length, N initial represents the preconfigured resource length, and K represents the scaling factor.

[0417] In some embodiments, the method further comprises:

[0418] The first terminal determines the bit length of the first domain according to the second frequency domain information.

[0419] In this implementation, the second frequency domain information can be used to determine the bit length of the first domain in addition to the frequency domain resource length indicated by 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.

[0420] As mentioned above, the FDRA field of DCI format 4_2 is divided into three modes: resource indication type 0, resource indication type 1, and dynamic indication. The lengths of the FDRA fields of different modes may be different. Therefore, for the case where the first DCI is DCI format 4_2, the first terminal can determine the length of the first field according to the second frequency domain information.

[0421] In some embodiments, the second frequency domain information includes a reference frequency domain length;

[0422] The first terminal determines, according to the second frequency domain information, a length of the first domain, including at least one of the following:

[0423] In a case where the resource indication type of the first domain is resource indication type 0, the length of the first domain determined by the first terminal is M bits, wherein M is obtained according to a reference frequency domain length included in the second frequency domain information;

[0424] 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;

[0425] 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;

[0426] in, Indicates the reference frequency domain length.

[0427] In some embodiments, the first terminal determines the first frequency domain information and / or the second frequency domain information, including:

[0428] 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;

[0432] Optionally, the first configuration parameter includes at least one of the following:

[0433] A first RIV for determining the first frequency domain information;

[0434] length information corresponding to the first frequency domain information;

[0435] Starting position information corresponding to the first frequency domain information;

[0436] and / or,

[0437] The second configuration parameter includes at least one of the following:

[0438] A second RIV for determining the second frequency domain information;

[0439] length information corresponding to the second frequency domain information;

[0440] The starting position information corresponding to the second frequency domain information.

[0441] Example 1: The network device configures the RIV values ​​corresponding to the reference frequency domain range and the actual frequency domain range respectively. That is, the first configuration parameter is the RIV value corresponding to the reference frequency domain range, and the second configuration parameter is the RIV value corresponding to the actual frequency domain range.

[0442] Example 2: The reference frequency domain range and the actual frequency domain range share the starting PRB information, and the network device configures the RIV value of the reference frequency domain range and the length information of the actual frequency domain range. That is, the first configuration parameter is the RIV value corresponding to the reference frequency domain range, and the second configuration parameter is the length information of the actual frequency domain range.

[0443] Example 3: The reference frequency domain range and the actual frequency domain range share the starting PRB information, and the network device configures the RIV value of the actual frequency domain range and the length information of the reference frequency domain range. That is, 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.

[0444] Example 4: The reference frequency domain range and the actual frequency domain range share the end PRB information, and the network device configures the RIV value of the reference frequency domain range and the starting position information of the actual frequency domain range. That is, 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 of the actual frequency domain range.

[0445] Example 5: The reference frequency domain range and the actual frequency domain range share the end PRB information, and the network device configures the RIV value of the actual frequency domain range and the starting position information of the reference frequency domain range. That is, 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.

[0446] In the embodiment of the present application, two ways of interpreting the first domain can be defined, namely, a first interpretation method and a second interpretation method, wherein the first interpretation method refers to a method in which the terminal interprets the first domain according to a reference frequency domain range, and the second interpretation method refers to a method in which the terminal interprets the first domain according to an actual frequency domain range. The following describes implementation methods related to the interpretation methods.

[0447] 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:

[0448] 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;

[0449] The first interpretation method is a method of using the second frequency domain information to interpret the first domain.

[0450] In some embodiments, the first terminal determines the frequency domain resources indicated by the first domain according to the second frequency domain information or the first frequency domain information, including:

[0451] 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.

[0452] Here, when it is determined not to use the first interpretation method, the first terminal may use 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.

[0453] In some embodiments, the method further comprises:

[0454] The first terminal determines whether to use the first interpretation method to interpret the first domain according to a preconfigured first association relationship, where the first association relationship is used to determine the interpretation method of the first domain;

[0455] or;

[0456] The first terminal determines, according to the received third configuration parameter of the network device, whether to use the first interpretation method to interpret the first domain;

[0457] or,

[0458] The first terminal determines, according to the second field of the first DCI, whether to use the first interpretation method to interpret the first field.

[0459] This implementation provides the above three parallel schemes to determine the interpretation method of the first domain. When the high layer is pre-configured with a first association relationship, the first terminal can determine whether to use the first interpretation method to interpret the first domain according to 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 according to the third configuration parameter sent by the network device, and 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 according to 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 application does not limit this.

[0460] In some embodiments, the first terminal determines, according to the second field of the first DCI, whether to interpret the first field in the first interpretation manner, including:

[0461] Determine, according to the received high-layer signaling, that the second field of the first DCI is used to indicate a manner of interpreting the first field;

[0462] According to the second domain, it is determined whether to use the first interpretation method to interpret the first domain.

[0463] In this implementation, the 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.

[0464] In some embodiments, the first association relationship includes at least one of the following:

[0465] a correlation between the search space and the interpretation of the first domain;

[0466] An association relationship between a group radio network temporary identifier (Group Radio Network Temporary Identifier, G-RNTI) and a way of interpreting the first domain.

[0467] In some embodiments, the method further comprises at least one of the following:

[0468] 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;

[0469] 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.

[0470] In some embodiments, the second field is an interpretation mode indication field, and the second field is located after the existing DCI field.

[0471] Specifically, an FDRA field interpretation mode indication field can be introduced in DCI format 4_0 / 4_1 / 4_2, and this indication field is placed after the last DCI field of the existing DCI field. This indication field can be configured to be parsed only by Redcap UE and cannot be parsed by Normal UE.

[0472] Optionally, the second field is located after the third field of the first DCI;

[0473] The first DCI is DCI format 4_0, and the third field is an MCCH change notification field (ie, an "MCCHchange notification" field); or,

[0474] The first DCI is DCI format 4_1, and the third field is a PDSCH to hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) feedback timing indicator field (ie, a "PDSCH-to-HARQ_feedback timing indicator" field); or,

[0475] The first DCI is DCI format 4_2, and the third field is a demodulation reference signal (DemodulationReference Signal, DMRS) sequence initialization field (ie, "DMRS sequence initialization" field).

[0476] In some embodiments, the second domain is a virtual resource block (VRB)-PRB mapping domain.

[0477] Optionally, 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.

[0478] In some embodiments, the method further comprises:

[0479] 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.

[0480] 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.

[0481] In some embodiments, 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, including:

[0482] In a case where 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;

[0483] 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.

[0484] 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.

[0485] In some embodiments, 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, including:

[0486] When the RIV corresponding to the PRB range indicated by the first domain is less than or equal to the RIV maximum threshold, the first terminal determines to receive the broadcast service scheduled by the first DCI;

[0487] 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;

[0488] in, represents the RIV maximum threshold value, Represents the CFR range of the common frequency domain resource part of the first terminal.

[0489] In this implementation mode, 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.

[0490] In some embodiments, the method further comprises:

[0491] 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.

[0492] 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.

[0493] The embodiment of the present application can be applied to 5G NR system and can also be applied to other systems. In the embodiment of the present application, the network device can schedule two terminals with two frequency domain resource configurations to receive the same data through the same downlink control information.

[0494] Figures 5 and 6 A schematic diagram of an applicable scenario of an embodiment of the present application is shown. 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.

[0495] In order to better understand the technical solutions of the embodiments of the present application, specific embodiments are provided below for illustrative purposes.

[0496] Embodiment 1:

[0497] 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:

[0498] Step 1a: The network device configures relevant parameters of the reference frequency domain range and the actual frequency domain range through system information.

[0499] Step 1b: The type 1 terminal obtains a reference frequency domain range and an actual frequency domain range, which may include the following methods:

[0500] (1) Type 1 terminals obtain the reference frequency domain range, including the reference frequency domain starting position information and the 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 the actual frequency domain length information, through the RIV value in the "cfr-ConfigMCCH-MTCH-redcap" parameter in the system information.

[0501] (2) Type 1 terminals obtain the reference frequency domain range, including the reference frequency domain starting position information and the 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.

[0502] (3) Type 1 terminals obtain the reference frequency domain range, including the reference frequency domain starting position information and the 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 end 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 (obtain the end PRB information through S+L), and then obtain the start PRB information of the actual frequency domain range through the "cfr-ConfigMCCH-MTCH-Start-redcap" parameter in the system information.

[0503] 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.

[0504] 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:

[0505] (1d-1) Type 1 terminals parse the RIV value in the FDRA field and use the resource length of the starting BWP / CORESET and RIV definition, calculate L′ RBs and RB′ start .

[0506] (1d-2) Type 1 terminal based on the resource length of the starting BWP / CORESET The length of the reference resource The relationship between and determines the value of the scaling factor K. but Otherwise, K=1.

[0507] (1d-3) Type 1 terminal according to the formula L RB =K×L′ RBs Calculate the frequency domain resource length indicated by the FDRA field (i.e., L RB ).

[0508] (1d-4) Type 1 terminal according to the formula RB Start =K×RB′ start Calculate the frequency domain resource starting PRB (RB) indicated by the FDRA field Start ), here, RB Start by As the starting PRB reference point.

[0509] Step 1e: The type 1 terminal determines 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 range of the actual received broadcast service. The actual frequency domain starting position is The specific method is as follows:

[0510] (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 may be, for example:

[0511] satisfy and or,

[0512] RB' Start and LRB Calculate the RIV according to the first CFR range, and the calculated RIV is less than

[0513] Among them, RB Start and L RB It is the value parsed from the FDRA domain. Other parameters are the values ​​obtained from high-level configuration.

[0514] (1e-2) Otherwise, the terminal discards the broadcast service indicated by this downlink control information.

[0515] If a type 1 terminal is interested in the broadcast service but cannot receive the broadcast service because the indicated PRB exceeds the terminal's capability, the type 1 terminal may report the event to the network device after entering the RRC connected state. The reported information may include the broadcast G-RNTI and / or the receiving capability of the type 1 terminal.

[0516] This embodiment provides a solution for a type 1 terminal to parse the FDRA field using a reference CFR range, and for a type 1 terminal to determine whether it is capable of receiving the broadcast service indicated by the downlink control information. In this embodiment, when sending a broadcast message, the network device does not know whether there is a type 1 terminal among the receiving terminals, and cannot guarantee that all broadcast scheduling can meet the ability of the type 1 terminal to receive the broadcast service. Therefore, the type 1 terminal needs to parse the broadcast control signaling to determine whether it is capable of receiving the data information of the broadcast service, and report the subsequent trigger event.

[0517] Embodiment 2:

[0518] 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_1) for scheduling multicast services. Compared with embodiment 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, and the specific configuration idea is similar to the ideas (1) to (3) in embodiment 1.

[0519] 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:

[0520] 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.

[0521] 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

[0522] The network device configures the second CFR range (i.e., reference CFR range) for the type 1 terminal through the "locationAndBandwidthMulticast-r19-Reference" parameter in the UE-specific RRC signaling. The second CFR range can be the CFR range of the type 2 terminal receiving the multicast service. The type 1 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

[0523] Step 2b: The type one terminal obtains a reference frequency domain range and an actual frequency domain range.

[0524] 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.

[0525] Step 2d: Type 1 terminal receives the DCI sent by the network device and and Interpret the FDRA field in DCI format 4_1. The specific method is as follows:

[0526] (2d-1) Type 1 terminals parse the RIV value in the FDRA field and use the resource length of the starting BWP / CORESET and RIV definition, calculate L′ RBs and RB′ start .

[0527] (2d-2) Type 1 terminal based on the resource length of the starting BWP / CORESET The length of the reference resource The relationship between and determines the value of the scaling factor K. but Otherwise, K=1.

[0528] (2d-3) Type 1 terminal according to formula L RB =K×L′ RBsCalculate the frequency domain resource length indicated by the FDRA field (i.e., L RB ).

[0529] (2d-4) Type 1 terminal according to the formula RB Start =K×RB′ start Calculate the frequency domain resource starting PRB (RB) indicated by the FDRA field Start ), here, RB Start by As the starting PRB reference point.

[0530] This embodiment provides a solution in which a network device directly configures a reference CFR range for a type-one terminal, and the type-one terminal uses the reference CFR range to parse the FDRA domain.

[0531] Embodiment 3:

[0532] 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_2) for scheduling multicast services. Compared with embodiment 2, the main difference is that the determination of the FDRA field length needs to be determined based on the reference CFR length.

[0533] Step 3a: the same as step 2a of Example 2;

[0534] Step 3b: the same as step 2b of Example 2;

[0535] 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.

[0536] 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:

[0537] 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 Determine the number of RBGs

[0538] Resource allocation type 1: Type 1 The terminal parses the RIV value in the FDRA field and and RIV definition to obtain L RB and RB Start , and is As the starting PRB reference point.

[0539] Type 1 terminals determine the length of the FDRA field in the following ways:

[0540] If the configuration is resource allocation type 0, the length of the FDRA field is bit;

[0541] If resource allocation type 1 is configured, the length of the FDRA field is

[0542] If the configuration is dynamic resource allocation type, the length of the FDRA field is

[0543] This embodiment provides a type 1 terminal according to the reference resource length A scheme to determine the length of the FDRA field in DCI format 4_2.

[0544] Embodiment 4:

[0545] This embodiment is used to introduce a feasible solution for a type one terminal to determine 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 high layer signaling.

[0546] Solution 1: Introduce an "FDRA field interpretation method" indication field (i.e., the second field) in DCI format 4_0 / 4_1 / 4_2. This indication 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.

[0547] 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.

[0548] 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. The length of this field can be 1 bit, for example, "1" indicates the first interpretation method, and "0" indicates the second interpretation method.

[0549] A DCI field is added after all configuration DCI fields or "DMRS sequence initialization" fields in DCI format 4_2 to indicate the FDRA field interpretation method. This field can be determined whether it exists in DCI format 4_2 based on high-level 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. In addition, the length of DCI format 4_2 received by type 1 terminals and type 2 terminals should be the same.

[0550] When a type 1 terminal receives a DCI format 4_0 / 4_1 / 4_2 containing an "FDRA field interpretation method" indication field, it needs to parse the "FDRA field interpretation method" indication field. If this field indicates the first interpretation method, the type 1 terminal parses the FDRA field content according to the reference CFR range; if this field indicates the second interpretation method, the type 1 terminal parses the FDRA field content according to the actual CFR range.

[0551] When a type 2 terminal receives a DCI format 4_0 / 4_1 / 4_2 containing an "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 manner.

[0552] A high-level parameter (i.e., the first parameter) can be introduced at the high level as a switch indication of whether the "FDRA domain interpretation method" indication field can be used to indicate the FDRA domain interpretation method. The scope of this high-level parameter may be a certain G-RNTI, or a certain DCI format, or a certain carrier. When the high level configures this parameter, the "FDRA domain interpretation method" indication field can be used to indicate the FDRA domain interpretation method; if it is in the default state, the "FDRA domain interpretation method" indication field cannot be used to indicate the FDRA domain interpretation method.

[0553] 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 correspondence is indicated, the first interpretation method is adopted; otherwise, the second interpretation method is adopted.

[0554] 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.

[0555] A high-level parameter (i.e., the second parameter) can be introduced at the high level as a switch indication of whether the "VRB-to-PRB mapping" field can be used to indicate the FDRA domain interpretation method, such as ReusevrbtoprbmappingEnabling-redcap. The scope of this high-level parameter may be a certain G-RNTI, or a certain DCI format, or a certain carrier. When the high level configures this parameter, the "VRB-to-PRB mapping" field can be used to indicate the FDRA domain interpretation method; if it is in the default state, the "VRB-to-PRB mapping" field cannot be used to indicate the FDRA domain interpretation method.

[0556] Solution 3: Introduce a FDRA domain interpretation configuration parameter (e.g., Fdratype-redcap) in the system information (e.g., SIB 20) to indicate the FDRA domain interpretation method of 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 uses the first interpretation method to interpret the FDRA domain; if the upper layer does not configure this parameter or indicates the second interpretation method, the terminal uses the second interpretation method to interpret the FDRA domain.

[0557] Solution 4: Introduce reference frequency domain range indication configuration parameters (e.g., locationAndBandwidthMulticast-r19-Reference or Fdratype-redcap) in UE-specific information (e.g., CFR-ConfigMulticast) to indicate which interpretation method DCI format 4_1 / 4_2 uses to interpret the FDRA domain. 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 domain; 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 domain.

[0558] Solution 5: Associate the search space with the FDRA domain interpretation method, and the type one terminal determines which interpretation method to use to interpret the FDRA domain based on the search space corresponding to the blind monitoring MO. For example, associate the MO corresponding to the search space with the FDRA domain interpretation method through high-level parameters. When the type one terminal blindly monitors and monitors DCI format4_0 / 4_1 / 4_2, if the MO is associated with the first interpretation method, the type one terminal uses the first interpretation method to interpret the FDRA domain; otherwise, the type one terminal uses the second interpretation method to interpret the FDRA domain.

[0559] Solution 6: Associate the G-RNTI with the FDRA domain interpretation method, and the type 1 terminal determines which interpretation method to use to interpret the FDRA domain based on the G-RNTI that parses the downlink control information. For example, associate the G-RNTI with the FDRA domain interpretation method through high-level parameters. When the type 1 terminal monitors that the G-RNTI of DCI format4_0 / 4_1 / 4_2 is associated with the first interpretation method, the type 1 terminal uses the first interpretation method to interpret the FDRA domain; otherwise, the type 1 terminal uses the second interpretation method to interpret the FDRA domain.

[0560] The above methods can be applied to DCI format 4_0 / 4_1 / 4_2 independently 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 scheme without limiting any combination.

[0561] In summary, in the embodiments of the present application, terminals with different frequency domain resource configurations can be scheduled by the same scheduling signaling, thereby saving signaling overhead.
