[0155] FIG2 is an interactive diagram of a frequency domain resource allocation method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a frequency domain resource allocation method, which includes:
[0156] Step S2101: The network device sends frequency domain resource indication information to the terminal.
[0157] The terminal may be a full-duplex capable terminal, for example, a terminal supporting sub-band full-duplex (SBFD) communication (i.e., an SBFD aware UE). Alternatively, the terminal may be a half-duplex capable terminal or a full-duplex capable terminal in hardware, which is not limited in the embodiments of the present disclosure.
[0158] In some embodiments, the network device may configure an uplink subband (UL subband) for uplink transmission for the terminal within a first type of time unit.
[0159] The transmission direction of the first type of time unit can be downlink or flexible, that is, the first type of time unit can be a downlink time slot (DL slot) or a flexible time slot (flexible slot), or the first type of time unit can be a downlink symbol (DL symbol) or a flexible symbol (flexible symbol).
[0160] In some embodiments, the network device may allocate PDSCH resources to the terminal on a first type of time unit configured with a UL subband, where the first type of time unit configured with a UL subband may be referred to as a subband full-duplex time slot (SBFD slot) or a subband full-duplex symbol (SBFD symbol).
[0161] It should be noted that the transmission direction of the sub-band full-duplex time slot (SBFD slot) or the sub-band full-duplex symbol (SBFD symbol) may include downlink and uplink; or, the transmission direction of the SBFD slot or the SBFD symbol may include flexible and uplink; or, the transmission direction of the SBFD slot or the SBFD symbol may include downlink and flexible.
[0162] Optionally, the network device may send downlink control information (DCI) to the terminal. The DCI may include frequency domain resource indication information, so as to guide the terminal to receive the PDSCH and determine the frequency domain resources occupied by the PDSCH through the frequency domain resource indication information.
[0163] The frequency domain resource indication information is used to indicate the frequency domain resources occupied by the PDSCH in a first type of time unit configured with an uplink subband, and the transmission direction of the first type of time unit is downlink or flexible.
[0164] It should be noted that the frequency domain resource allocation method for PDSCH in related technologies supports Resource Allocation Type 1 (RA Type 1). Under RA Type 1, the PDSCH resources allocated to the terminal can be indicated by the continuous virtual resource blocks (VRBs) occupied by the PDSCH. For example, under RA Type 1, the PDSCH resources allocated to the terminal can be indicated by the starting VRB index and the number of VRBs.
[0165] RA Type 1 can support multiple resource mapping methods. For example, RA Type 1 can support interleaved mapping and non-interleaved mapping (such as localized mapping). Whether interleaved mapping or non-interleaved mapping, it is necessary to perform mapping between VRB and physical resource block (PRB) in the active downlink bandwidth part (active DL BWP).
[0166] For RA Type 1 with localized mapping, PDSCH resources need to be controlled within a DL subband. If PDSCH resources span two DL subbands, PDSCH mapped on the UL subband and guard band cannot be received. In this case, the terminal is very likely to be unable to demodulate the PDSCH normally, resulting in low PDSCH resource reception efficiency.
[0167] For RA Type 1 with interleaved mapping, the terminal and network equipment can use the sub-block interleaver agreed upon in the protocol to map VRBs and PRBs. However, it is very likely that the PRBs mapped by the VRBs will be outside the DL subband. The frequency domain resources outside the DL subband cannot be used for PDSCH transmission, resulting in poor downlink transmission performance.
[0168] In view of this, the rules of frequency domain resource indication information can be agreed upon in the protocol to ensure that the PDSCH resources indicated by the frequency domain resource indication information sent by the network device can be demodulated by the terminal and to ensure downlink transmission performance.
[0169] In some embodiments, the frequency domain resource indication information may not be used to indicate the consecutive VRBs occupied by the PDSCH. For example, the frequency domain resource indication information is only used to indicate the VRBs occupied by the PDSCH through a bitmap. The VRB positions indicated by the bitmap can be consecutive or flexibly dispersed according to channel requirements to ensure that the PRBs corresponding to the indicated VRBs are all within the DL subband range.
[0170] That is, the terminal does not expect the frequency domain indication information to be used to indicate the continuous VRBs occupied by the PDSCH, or in other words, the terminal does not expect the network device to use RA type 1 to indicate the frequency domain resources occupied by the PDSCH in the first type of time unit configured with the UL subband. Accordingly, the network device may not use RA type 1 to indicate the frequency domain resources occupied by the PDSCH when scheduling the PDSCH of the terminal in the first type of time unit configured with the UL subband. Optionally, when the network device schedules the PDSCH of the terminal in the first type of time unit configured with the UL subband, it may use resource allocation type 0 (RA type 0) to indicate the frequency domain resources occupied by the PDSCH.
[0171] In some embodiments, when the frequency-domain resource indication information is used to indicate consecutive VRBs occupied by the PDSCH, the resource mapping between the consecutive VRBs and the PRBs is non-interleaved mapping. By adopting non-interleaved mapping, the network device can limit the PDSCH resources to the range of a single DL subband, thereby avoiding the situation where the terminal cannot demodulate due to the PDSCH resources spanning two or more DL subbands.
[0172] That is, when the resource indication information is used to indicate the continuous VRBs occupied by the PDSCH, the terminal does not expect the resource mapping between the continuous VRBs and PRBs to be interleaved mapping, or in other words, when the network device schedules the PDSCH of the terminal on the first type of time unit configured with the UL subband, and uses RA type 1 to indicate the frequency domain resources occupied by the PDSCH, the terminal does not expect the resource mapping of continuous VRBs to PRBs to be interleaved mapping. Optionally, when the network device schedules the PDSCH of the terminal on the first type of time unit configured with the UL subband, it may use RA type 1 to indicate the frequency domain resources occupied by the PDSCH, and use non-interleaved mapping (such as local mapping) to perform resource mapping of continuous VRBs to PRBs.
[0173] In some embodiments, when the multiple time units occupied by the repeatedly transmitted PDSCH correspond to multiple time unit types, the frequency domain resource indication information is not used to indicate the consecutive VRBs occupied by the PDSCH. For example, when the multiple time units occupied by the repeatedly transmitted PDSCH correspond to multiple time unit types, the frequency domain resource indication information is only used to indicate the VRBs occupied by the PDSCH through a bitmap. The VRB positions indicated by the bitmap can be continuous or flexibly dispersed according to channel requirements to ensure that the PRBs corresponding to the indicated VRBs are all within the DL subband range.
[0174] That is, when the terminal does not expect that the multiple time units occupied by the repeatedly transmitted PDSCH correspond to multiple time unit types, the frequency domain indication information is used to indicate the continuous VRBs occupied by the PDSCH, or, when the PDSCH is repeatedly transmitted and spans different types of time units, the terminal does not expect the network device to use RA type 1 to indicate the frequency domain resources occupied by the PDSCH. Therefore, the network device does not use RA type 1 to indicate the frequency domain resources occupied by the PDSCH when the PDSCH is repeatedly transmitted and spans different types of time units. Optionally, the network device may use RA type 0 to indicate the frequency domain resources occupied by the PDSCH when the PDSCH is repeatedly transmitted and spans different types of time units.
[0175] In some embodiments, the network device may determine whether RA Type 1 resource indication mode can be used to send PDSCH in the first type of time unit based on whether the first PRB corresponding to the VRB packet occupied by PDSCH is within the frequency domain range of the downlink subband.
[0176] In some embodiments, when the first PRB corresponding to the VRB packet occupied by the PDSCH is within the frequency domain range of the downlink subband, the network device may use RA Type 1 as a resource indication method to transmit the PDSCH within the first type of time unit. In other words, when the PDSCH resources allocated by the network device to the terminal via RA Type 1 do not exceed the frequency domain range of the DL subband, the network device may transmit the PDSCH within the first type of time unit.
[0177] That is, when the frequency domain resource indication information is used to indicate the consecutive VRBs occupied by the PDSCH, and the first PRB corresponding to the VRB packet occupied by the PDSCH is within the frequency domain range of the downlink subband, the network device can send the PDSCH within the first type of time unit. Optionally, the resource mapping method between VRBs and PRBs can be interleaved mapping or non-interleaved mapping, which is not limited in the embodiments of the present disclosure.
[0178] In some embodiments, when the first PRB corresponding to the VRB packet occupied by the PDSCH is outside the frequency domain range of the downlink subband, the network device may not use the RA Type 1 resource indication method to send the PDSCH in the first type of time unit. In other words, when the PDSCH resources allocated by the network device to the terminal through RA Type 1 exceed the frequency domain range of the DL subband, the network device may not send the PDSCH in the first type of time unit.
[0179] That is, when the frequency domain resource indication information indicates the continuous VRBs occupied by the PDSCH and the first PRB corresponding to the VRB packet occupied by the PDSCH is outside the frequency domain range of the downlink subband, the network device may not send the PDSCH in the first type of time unit.
[0180] In some embodiments, the network device may also give up at least part of the transmission opportunities of sending PDSCH when the frequency domain resource indication information indicates the continuous VRBs occupied by PDSCH and the first PRB corresponding to the VRB packet occupied by PDSCH is outside the frequency domain range of the downlink subband.
[0181] For example, when the frequency domain resource indication information indicates that the continuous VRBs occupied by PDSCH and the first PRB corresponding to the VRB packet occupied by PDSCH is outside the frequency domain range of the downlink subband, the network device may give up the transmission opportunity of sending PDSCH, that is, give up all transmission opportunities of sending PDSCH, so as to achieve the effect of not sending PDSCH on the first type of time unit.
[0182] Optionally, when the frequency domain resource indication information indicates the continuous VRBs occupied by the PDSCH and the first PRB corresponding to the VRB packet occupied by the PDSCH is outside the frequency domain range of the downlink sub-band, the network device can also determine the transmission timing of the PDSCH to be abandoned based on the number of first PRBs located outside the frequency domain range of the downlink sub-band.
[0183] For example, when the frequency domain resource indication information indicates the continuous VRBs occupied by the PDSCH, the first PRB corresponding to the VRB packet occupied by the PDSCH is outside the frequency domain range of the downlink sub-band, and the number of the first PRBs outside the frequency domain range of the downlink sub-band is less than or equal to the first value, the network device may abandon some transmission opportunities for sending the PDSCH, such as abandoning the transmission opportunity of the first PDSCH in the PDSCH, and some frequency domain resources occupied by the transmission opportunity of the first PDSCH are outside the frequency domain range of the downlink sub-band, so as to achieve the effect of only sending the PDSCH within the frequency domain range of the downlink sub-band when sending the PDSCH on the first type of time unit. Optionally, the resource mapping method between VRBs and PRBs can be interleaved mapping or non-interleaved mapping, which is not limited in the embodiments of the present disclosure.
[0184] For another example, the network device may abandon the transmission opportunity of sending PDSCH when the frequency domain resource indication information indicates the consecutive VRBs occupied by PDSCH, the first PRB corresponding to the VRB packet occupied by PDSCH is outside the frequency domain range of the downlink sub-band, and the number of first PRBs outside the frequency domain range of the downlink sub-band is greater than the second value, that is, abandon all transmission opportunities for sending PDSCH, so as to achieve the effect of not sending PDSCH on the first type of time unit.
[0185] Optionally, the first value and the second value may be the same. For example, the first value and the second value may be the amount of resources corresponding to a virtual resource block bundle (VRB bundle).
[0186] The VRB bundle may be a minimum VRB set in the VRB and PRB mapping process. Optionally, the size of the VRB bundle may be determined according to system configuration.
[0187] In some embodiments, the frequency domain resource indication information may be used to indicate consecutive VRBs occupied by the PDSCH within the frequency domain range of the downlink subband, so as to ensure that the terminal can normally demodulate the PDSCH.
[0188] For example, the network device may use RA Type 1 to indicate the frequency domain resources occupied by the PDSCH within the downlink sub-band frequency domain range.
[0189] Optionally, the resource mapping method between VRB and PRB can be non-interleaved mapping or interleaved mapping, which is not limited in the embodiments of the present disclosure. When the resource mapping method between VRB and PRB is non-interleaved mapping, the network device can determine the frequency domain resources occupied by PDSCH based on the frequency band obtained by cascading multiple downlink subbands within the downlink subband frequency domain range, so as to allocate the frequency domain resources occupied by PDSCH to the terminal; when the resource mapping method between VRB and PRB is interleaved mapping, the network device can determine the frequency domain resources occupied by PDSCH within the multiple downlink subband frequency domain ranges in the first type of time unit, so as to allocate the frequency domain resources occupied by PDSCH to the terminal within the multiple downlink subband frequency domain ranges in the first type of time unit.
[0190] For example, when the resource mapping method between VRB and PRB is non-interleaved mapping, the network equipment can cascade multiple downlink sub-bands within the downlink sub-band frequency domain to obtain a frequency band with a larger bandwidth. In the cascaded frequency band, each VRB and PRB can be renumbered so that the numbers of VRB and PRB are continuous, so that mapping can be performed based on the renumbered VRB and PRB to allocate frequency domain resources occupied by PDSCH to the terminal.
[0191] For another example, when the resource mapping mode between VRB and PRB is interleaved mapping, the network device may divide the VRB or VRB bundle into two parts, and allocate frequency domain resources occupied by the PDSCH to the terminal in two DL subbands respectively.
[0192] In some embodiments, the names of messages, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.
[0193] In some embodiments, the terms "physical downlink shared channel (PDSCH)", "DL data", etc. may be used interchangeably.
[0194] In some embodiments, the terms "physical resource block (PRB)", "resource block (RB)", "sub-carrier group (SCG)", "resource element group (REG)", "PRB pair", "RB pair", "resource element (RE)", "sub-carrier (sub-carrier)" and the like can be used interchangeably.
[0195] In some embodiments, terms such as "slot", "sub-slot", "mini-slot", "symbol", "symbol", "frame", "radio frame", "subframe", and "transmission time interval (TTI)" can be used interchangeably.
[0196] Step S2102: The terminal determines whether to receive the PDSCH based on the frequency domain resource indication information, and / or determines the frequency domain resources occupied by the PDSCH.
[0197] In some embodiments, the terminal may receive frequency domain resource indication information sent by a network device.
[0198] In some embodiments, the terminal may receive and demodulate the PDSCH based on the frequency domain resource indication information received from the network device, that is, determine whether to receive the PDSCH and / or determine the frequency domain resources occupied by the PDSCH.
[0199] In some embodiments, the terminal does not expect the frequency domain resource indication information to indicate the consecutive VRBs occupied by the PDSCH. Therefore, when the frequency domain resource indication information is used to indicate the consecutive VPBs occupied by the PDSCH, the terminal may not receive the PDSCH. In other words, when the network device uses RA Type 1 to indicate the frequency domain resources occupied by the PDSCH, the terminal may not receive the PDSCH.
[0200] In some embodiments, when the frequency-domain resource indication information is used to indicate the consecutive VRBs occupied by the PDSCH, the terminal does not expect the resource mapping method between the consecutive VRBs and the PRBs to be interleaved mapping. Therefore, when the frequency-domain resource indication information is used to indicate the consecutive VRBs occupied by the PDSCH and the resource mapping method between the consecutive VRBs and the PRBs is interleaved mapping, the terminal may not receive the PDSCH. That is, when the network device uses RA Type 1 with interleaved mapping to indicate the frequency-domain resources occupied by the PDSCH, the terminal may not receive the PDSCH.
[0201] It should be noted that the terminal does not receive the PDSCH, that is, the terminal discards the PDSCH, or in other words, the terminal discards all transmission opportunities of the PDSCH.
[0202] In some embodiments, when the frequency domain resource indication information is used to indicate the VRBs occupied by the PDSCH through a bitmap, the terminal can receive the PDSCH. That is, when the network device uses RA Type 0 to indicate the frequency domain resources occupied by the PDSCH, the terminal can receive the PDSCH.
[0203] In some embodiments, when the frequency domain resource indication information is used for consecutive VRBs occupied by the PDSCH and the resource mapping between consecutive VRBs and PRBs is non-interleaved mapping, the terminal can receive the PDSCH. That is, when the network device uses RA Type 1 with localized mapping to indicate the frequency domain resources occupied by the PDSCH, the terminal can receive the PDSCH.
[0204] In some embodiments, the frequency domain resource indication information is used to indicate the continuous VRBs occupied by the PDSCH, and the first PRB corresponding to the VRB packet occupied by the PDSCH is outside the frequency domain range of the downlink subband. The terminal can discard at least part of the transmission opportunities of the PDSCH.
[0205] For example, the frequency domain resource indication information is used to indicate the continuous VRBs occupied by the PDSCH, and the first PRB corresponding to the VRB packet occupied by the PDSCH is located outside the frequency domain range of the downlink subband. The terminal can discard the transmission opportunity of the PDSCH, such as discarding all transmission opportunities of the PDSCH, that is, discarding the entire PDSCH.
[0206] Optionally, in this case, the resource mapping relationship between VRBs and PRBs may be interleaved mapping or non-interleaved mapping (such as local mapping), which is not limited in the embodiments of the present disclosure.
[0207] In some embodiments, the frequency domain resource indication information is used to indicate the consecutive VRBs occupied by the PDSCH. When the first PRB corresponding to at least part of the VRB packets occupied by the PDSCH is outside the frequency domain range of the downlink subband, the terminal can determine the PDSCH transmission opportunity to be discarded based on the number of first PRBs outside the frequency domain range of the downlink subband. In this case, the resource mapping relationship between VRBs and PRBs can be interleaved mapping or non-interleaved mapping (such as local mapping), which is not limited in the embodiments of the present disclosure.
[0208] Optionally, the frequency domain resource indication information is used to indicate the continuous VRBs occupied by the PDSCH, and the first PRB corresponding to at least part of the VRB packets occupied by the PDSCH is located outside the frequency domain range of the downlink subband, and the number of first PRBs located outside the frequency domain range of the downlink subband is less than or equal to the first value. In this case, the terminal can discard the transmission opportunity of the first PDSCH in the PDSCH.
[0209] Part of the frequency domain resources occupied by the first PDSCH transmission opportunity is outside the frequency domain range of the downlink sub-band. That is, the terminal can discard the PDSCH transmission opportunity whose frequency domain resources exceed the frequency domain range of the downlink sub-band.
[0210] That is to say, the frequency domain resource indication information is used to indicate the continuous VRBs occupied by the PDSCH, the first PRB corresponding to at least part of the VRB packets occupied by the PDSCH is located outside the frequency domain range of the downlink sub-band, and the number of first PRBs outside the downlink sub-band frequency domain range is less than or equal to the first value. The terminal can still receive the PDSCH and only receive the PDSCH within the downlink sub-band frequency domain range.
[0211] Optionally, the frequency domain resource information is used to indicate the continuous VRBs occupied by the PDSCH, the first VRB occupied by the PDSCH is located outside the frequency domain range of the downlink subband, and the number of first PRBs located outside the frequency domain range of the downlink subband is greater than the first value. The terminal can discard the transmission opportunity of the PDSCH, such as discarding all transmission opportunities of the PDSCH, that is, discarding the entire PDSCH.
[0212] The first value may be the amount of resources corresponding to a VRB bundle.
[0213] In some embodiments, the frequency domain resource indication information is used to indicate the consecutive VRBs occupied by the PDSCH, and the terminal may determine the frequency domain resources occupied by the PDSCH within the frequency domain range of the downlink subband.
[0214] For example, the network device may use RA Type 1 to indicate the frequency domain resources occupied by PDSCH within the downlink subband frequency domain range. Accordingly, the terminal may determine the frequency domain resources occupied by PDSCH within the downlink subband frequency domain range based on the indication of the network device.
[0215] Optionally, the resource mapping mode between VRBs and PRBs can be non-interleaved mapping or interleaved mapping, which is not limited in the embodiments of the present disclosure. The following describes the process of the terminal determining the frequency domain resources occupied by the PDSCH when the resource mapping mode between VRBs and PRBs is non-interleaved mapping and interleaved mapping.
[0216] The resource mapping mode between VRB and PRB is non-interleaved mapping. The terminal can determine the frequency domain resources occupied by PDSCH based on the frequency band obtained by concatenating multiple downlink subbands within the downlink subband frequency domain range.
[0217] For example, the terminal can cascade multiple downlink sub-bands within the downlink sub-band frequency domain to obtain a frequency band with a larger bandwidth. In the cascaded frequency band, each VRB and PRB can be renumbered so that the numbers of VRB and PRB are continuous, so that mapping can be performed based on the renumbered VRB and PRB to determine the frequency domain resources occupied by PDSCH.
[0218] The resource mapping mode between VRB and PRB is interleaved mapping, and the terminal can respectively determine the frequency domain resources occupied by the PDSCH within the frequency domain range of multiple downlink sub-bands in the first type of time unit.
[0219] For example, if the resource mapping mode between VRBs and PRBs is interleaved mapping, the terminal may divide the VRB or VRB bundle into two parts, and determine the frequency domain resources occupied by the PDSCH in two DL subbands respectively.

[0244] In an embodiment of the present disclosure, step S3201 may be combined with step S3101 of FIG. 3A .
[0245] To facilitate a better understanding of the frequency domain resource allocation method provided by the embodiment of the present disclosure, the frequency domain resource allocation method provided by the embodiment of the present disclosure is described in detail below based on examples.
[0246] In some embodiments, the terminal may support multiple versions of the 5G standard and may have half-duplex or full-duplex communication capabilities, which are not limited in the embodiments of the present disclosure. When the network device performs full-duplex operation in the downlink time slot of the time division duplex (TDD) frequency band, the network device may simultaneously schedule downlink data and uplink data in the downlink time slot of the TDD frequency band.
[0247] Optionally, when performing full-duplex operation, the network device may adopt any resource allocation as shown in FIG4 . Referring to FIG4 , FIG4 is a schematic diagram of frequency domain resources for full-duplex communication according to an embodiment of the present disclosure. FIG4 shows the following three resource allocations:
[0248] The frequency domain resources used for downlink and uplink transmission within a DL slot are independent and non-overlapping;
[0249] The frequency domain resources used for downlink and uplink transmission in the DL slot completely overlap;
[0250] The frequency domain resources used for downlink transmission and uplink transmission in the DL slot partially overlap.
[0251] For the TDD frequency band, the center frequency bands of the DL BWP and the UL BWP need to be aligned. If the current time division duplex uplink-downlink configuration (TDD UL-DL configuration) is DDDDDDSUUU, and the bandwidth of the DL BWP in the DL slot is different from the bandwidth of the UL BWP in the UL slot, the DL BWP and UL BWP configuration as shown in Figure 5 can be adopted. See Figure 5, which is a schematic diagram of the DL BWP and UL BWP configuration according to an embodiment of the present disclosure.
[0252] Optionally, the network device can schedule the downlink transmission of the terminal through downlink control information (DCI) in multiple formats. For example, the network device can schedule the downlink transmission of the terminal through DCI format 1-0, DCI format 1-1, DCI format 1-2, DCI format 1-3, etc. Optionally, the network device can also schedule the downlink transmission of the terminal through any other DCI for scheduling downlink transmission.
[0253] Alternatively, the network device may configure a periodically transmitted PDSCH for the terminal through Radio Resource Control (RRC) signaling, such as a semi-persistent scheduling (SPS) physical downlink shared channel PDSCH. The embodiments of the present disclosure do not limit the type and indication method of the uplink transmission.
[0254] Optionally, the downlink transmission may be within the DL subband of the SBFD slot, or the downlink transmission may be within the active DL BWP of the non-SBFD slot, which is not limited in the embodiments of the present disclosure.
[0255] Refer to Figure 6, which is a schematic diagram of a frequency domain resource according to an embodiment of the present disclosure. As shown in Figure 6, taking the TDD UL-DL configuration configured by the network device as DDDFU as an example, if the UL subband configured by the network device for the terminal is located in slot#0, slot#1, slot#2 and slot#4, the UL subband in the frequency domain is located in the middle position of the carrier or BWP, that is, the SBFD slot in the frequency domain includes at least one UL subband and two DL subbands located on both sides of the UL subband.
[0256] Based on the above example, the terminal may not expect the frequency domain resource indication information to be used to indicate the consecutive VRBs occupied by the PDCSH. That is, when the network device schedules PDSCH for the terminal in the SBFD slot, the terminal may not expect the network device to indicate the PDSCH transmitted in the SBFD slot through RA Type 1.
[0257] Optionally, the PDSCH may be a single PDSCH transmission, or the PDSCH may have repetition transmission enabled, or the PDSCH may be a multi-PDSCH transmission, which is not limited in the embodiments of the present disclosure.
[0258] It should be noted that if the network device schedules the terminal to receive PDSCH on the SBFD slot, and the terminal does not expect the resource allocation mode to be RA type 1, that is, the terminal can support the network device to indicate the resource allocation status of PDSCH in the frequency domain through RA type 0.
[0259] If the terminal does not expect the frequency domain resource indication information to be used to indicate the consecutive VRBs occupied by the PDCSH, the network device may not use RA Type 1 to indicate the frequency domain resources occupied by the PDSCH, so as to ensure that the frequency domain resource indication information sent by the network device to the terminal is not used to indicate the consecutive VRBs occupied by the PDSCH.
[0260] Optionally, when the network device uses RA type 1 to indicate the frequency domain resources occupied by the PDSCH on the SBFD slot to the terminal, the terminal may discard the PDSCH.
[0261] Optionally, when the network device uses RA type 1 to indicate the frequency domain resources occupied by the PDSCH on the SBFD slot to the terminal, the terminal may discard PDSCH transmission opportunities that are beyond the downlink subband frequency domain range.
[0262] When PDSCH is repeatedly transmitted, and the repeated transmission of PDSCH spans different time slot types, that is, some of the repeatedly transmitted PDSCH is located in a non-SBFD slot (such as a DL slot or a Flexible slot), and some of the repeatedly transmitted PDSCH is located in a SBFD slot. At this time, if the network device uses the RA type 1 resource indication method to allocate frequency domain resources for PDSCH, the terminal can receive the PDSCH on the non-SBFD slot and discard the PDSCH on the SBFD slot. If the network device indicates to the terminal that repeated transmission of PDSCH is enabled through the RA type 0 resource indication method, the terminal can receive PDSCH on both the non-SBFD slot and the SBFD slot.
[0263] In addition, when the frequency domain resource indication information is used to indicate the consecutive VRBs occupied by the PDSCH, the terminal may not expect that the resource mapping mode between the consecutive VRBs and PRBs is interleaved mapping.
[0264] It should be noted that if the network device schedules the terminal to receive PDSCH on the SBFD slot and the terminal does not expect the resource allocation mode to be RA type 1, the resource mapping mode between VRB and PRB is interleaved mapping, that is, the terminal can support the network device to indicate the resource allocation of PDSCH in the frequency domain through RA type 0 or RA Type 1, and the resource mapping mode between VRB and PRB is non-interleaved mapping.
[0265] Optionally, when the network device uses RA type 1 to indicate the frequency domain resources occupied by PDSCH on the SBFD slot to the terminal, and the resource mapping method between VRB and PRB is interleaved mapping, the terminal can discard PDSCH transmission opportunities that exceed the downlink subband frequency domain range.
[0266] When the network device uses RA type 1 to indicate the frequency domain resources occupied by the PDSCH on the SBFD slot to the terminal, and the resource mapping mode between VRB and PRB is interleaved mapping, the terminal can discard the PDSCH.
[0267] Optionally, when PDSCH is repeatedly transmitted, and the repeated transmission of PDSCH spans different time slot types, that is, part of the repeatedly transmitted PDSCH is located in a non-SBFD slot (such as a DL slot or a Flexible slot), and part of the repeatedly transmitted PDSCH is located in a SBFD slot. At this time, if the network device uses RA type 1 resource indication method to allocate frequency domain resources for PDSCH, and the resource mapping method between VRB and PRB is interleaved mapping, the terminal can receive the PDSCH on the non-SBFD slot and discard the PDSCH on the SBFD slot. If the network device indicates to the terminal through RA type 0 resource indication method or RA type 1 resource indication method that repeated transmission of PDSCH is enabled, and the resource mapping method between VRB and PRB is non-interleaved mapping, the terminal can receive PDSCH on both non-SBFD slot and SBFD slot.
[0268] In some embodiments, when the network device allocates frequency domain resources for the PDSCH on the SBFD slot using RA type 1 resource indication, the terminal may determine whether it needs to receive the PDSCH on the SBFD slot in the following manner:
[0269] When the PDSCH frequency domain resources allocated to the terminal by the network through the RA type 1 resource indication method exceed the frequency domain range of the DL subband, the terminal discards the PDSCH.
[0270] Optionally, the terminal may discard PDSCH transmission occasions that are beyond the DL subband frequency domain range.
[0271] Optionally, if the PDSCH frequency domain resources beyond the DL subband frequency domain range are less than or equal to one VRB bundle, the terminal can still receive the PDSCH, and the PDSCH is received within the frequency domain range of the DL subband.
[0272] Optionally, the terminal does not impose any limitation on the resource mapping mode between VRBs and PRBs, and the resource mapping mode between VRBs and PRBs may be localized mapping or interleaved mapping.
[0273] Taking the repeatedly transmitted PDSCH as an example, when the network device schedules the terminal to receive the PDSCH on the SBFD slot, the network device can indicate the PDSCH frequency domain resources of the terminal on the SBFD slot through RA type 1. Referring to Figure 7, Figure 7 is a schematic diagram of frequency domain resource allocation according to an embodiment of the present disclosure. The network device configures UL subbands on slot #2 and slot #3 for the terminal. The UL subband can be located at the center of the carrier. Repeated transmission can be enabled through DCI scheduling or activation of the PDSCH. The number of repeated transmissions can be R = 4. In this embodiment, it is assumed that the four repeated transmission opportunities of the PDSCH in the time domain occupy slot #0 to slot #3. As shown in Figure 7, the frequency domain resources occupied by the PDSCH on the SBFD slot exceed the range of the DL subband. In this case, the terminal may not receive the repeatedly transmitted PDSCH on slot #2 and slot #3. That is, the terminal can discard the repeatedly transmitted PDSCH on slot #2 and slot #3.
[0274] Optionally, when discarding the PDSCH repeatedly transmitted in slot#2 and slot#3, the terminal may first determine the number of resources exceeding the DL subband range. When the number of resources exceeding the DL subband range is less than N PRBs, the terminal may still receive the PDSCH normally.
[0275] Here, N may be a predefined value, or N may be a value configured by the network device through RRC signaling, which is not limited in the embodiments of the present disclosure.
[0276] In some embodiments, when the network device allocates frequency domain resources for the PDSCH on the SBFD slot using RA type 1 resource indication, the terminal may determine the frequency domain resource allocation of the PDSCH on the SBFD slot in the following manner:
[0277] When the network device indicates the PDSCH frequency domain resources on the SBFD slot to the terminal through RA type 1, the frequency domain resources occupied by the PDSCH exceed the resource range occupied by the DL subband. The terminal can determine the PDSCH within the DL subband range according to the frequency domain resource indication information indicated by RA type 1.
[0278] Optionally, the resource mapping mode between VRBs and PRBs is non-interleaved mapping, and the terminal may concatenate two DL subbands together to determine frequency domain resource allocation.
[0279] Optionally, the resource mapping mode between VRBs and PRBs is interleaved mapping, and the terminal may divide the VRB or VRB bundle into two parts, and determine the PRBs indicated by the frequency domain resource allocation in two DL subbands respectively.
[0280] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
