[0002] In a time division duplex (TDD) system, all frequency domain resources of a TDD carrier must have the same transmission direction at the same time, that is, uplink or downlink, which also results in the inability to flexibly configure the uplink and downlink time slot ratios of different frequency domain resources on a TDD carrier.

[0060] In some possible implementations, the terminal device of the embodiments of the present application may be a chip, a chip module, a device, a unit, etc., without specific limitation.

[0061] 3. Network equipment

[0062] A network device may be a device with transceiver functions and may be used to communicate with a terminal device.

[0063] In some possible implementations, the network device may be responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, data transmission and reception, etc. on the air interface side.

[0064] In some possible implementations, the network device may include a base station (BS) in a communication system or a device deployed in a radio access network (RAN) for providing wireless communication functions, that is, the network device may include a device in the RAN.

In addition, the AAU can implement some physical layer processing functions, radio frequency processing, and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer, under this network deployment, high-level signaling (such as RRC signaling) can be considered to be generated by the CU, sent by the DU, or sent by the DU and the AAU. It can be understood that the network device may include at least one of the CU, DU, and AAU.

[0086] 2. An Uplink Enhancement Method

[0087] 1. Description

[0088] SBFD can support uplink transmission and downlink transmission at the same time. When configuring SSB and SBFD at the same time, since SSB involves downlink transmission, it is necessary to study the impact of SSB on the uplink transmission or uplink reception of SBFD.

[0089] In specific implementation, since the network will configure SSB resources and SBFD resources, and there may be a certain relationship between the SSB resources and the SBFD resources, and this relationship may have a certain impact on whether SBFD uplink transmission or uplink reception can be performed, the present application can perform uplink transmission or uplink reception according to the resource configuration of SSB and SBFD, so as to ensure uplink transmission or uplink reception as much as possible in the configuration of SSB and SBFD and achieve uplink enhancement.

[0090] It should be noted that, for the terminal device side, the present application can achieve uplink transmission enhancement; and for the network device side, the present application can achieve uplink reception enhancement. The present application is mainly explained from the uplink transmission, and the uplink reception can be understood by the same logic, so it will not be repeated.

[0091] In combination with the above content, the technical solutions, beneficial effects, concepts, etc. involved in the embodiments of the present application are described in detail below.

[0092] 2. Specific instructions

[0093] It should be noted that the contents in the following sections may be combined and related to each other, may be parallel to each other, or may be independent of each other, and there is no specific limitation on this.

[0094] 1) SBFD

[0095]

symbol

[0096] In the time domain resources, the "symbol" described in this application can be an OFDM symbol, which can include a downlink symbol, an uplink symbol, and a flexible symbol. Among them, a downlink symbol can only support downlink transmission; an uplink symbol can only support uplink transmission; a flexible symbol can be configured by the network to support uplink transmission or downlink transmission, that is, it only supports one transmission mode.

[0097] Optionally, the symbol may be configured by the network through network signaling (such as MAC signaling, MAC CE, DCI, system information, dedicated information, UE-dedicated signaling, etc.).

[0098]

SBFD

[0099] In a TDD system, all frequency domain resources of a TDD carrier must have the same transmission direction at the same time, that is, uplink or downlink, which also results in the inability to flexibly configure the uplink and downlink time slot ratios of different frequency domain resources on a TDD carrier. In addition, with the diversification of services, especially considering the business needs of vertical industries, different services have certain differences in the requirements for uplink and downlink transmission, making a single uplink and downlink time slot ratio unable to meet the needs of different services.

[0100] In order to avoid the limitation of uplink and downlink time slot ratio as much as possible and taking into account the implementation complexity of network equipment, 3GPP is discussing SBFD, which is to divide non-overlapping uplink sub-bands and downlink sub-bands in the frequency domain of the same TDD carrier so as to support uplink and downlink transmission at the same time and improve spectrum utilization and flexibility.

[0101]

SBFD Resources

[0102] The network may configure SBFD resources through network signaling (such as DCI, MAC signaling, MAC CE, system information, dedicated information, UE dedicated signaling, etc.) Among them, SBFD resources may include time domain SBFD resources and frequency domain SBFD resources.

[0103] The time-domain SBFD resources may be understood as SBFD resources in the time domain, which may include SBFD symbols, SBFD time slots, SBFD mini time slots, SBFD subframes, and the like.

[0104] The frequency domain SBFD resources can be understood as SBFD resources in the frequency domain, which can include SBFD uplink subbands and SBFD downlink subbands, wherein the SBFD uplink subbands can be used for uplink transmission or uplink reception, and the SBFD downlink subbands can be used for downlink transmission.

[0105] The SBFD symbol can be understood as a symbol that has been configured to allow SBFD operation. In other words, the original symbol's attribute of supporting uplink transmission or downlink transmission is changed due to the configuration of SBFD operation.

[0106] Of course, the SBFD uplink subband can be called an "uplink subband"; the SBFD downlink subband can be called a "downlink subband". In addition, the present application can also replace "SBFD symbol" with "SBFD time slot", "SBFD mini-time slot", "SBFD subframe", etc. The meanings of their respective expressions are similar to those of "SBFD symbol" and are not specifically limited thereto.

[0107] Optionally, there may be a guard band between the uplink subband and the downlink subband, so that interference between the uplink and downlink can be avoided as much as possible through the guard band.

[0108] For example, Figure 2 As shown, time slot n includes multiple downlink symbols, and these downlink symbols only include downlink subbands; time slot n+1 includes multiple SBFD symbols, and the frequency domain resources of these SBFD symbols include uplink subbands, downlink subbands and guard bands.

[0109] Optionally, the SBFD symbols may include SBFD downlink symbols, SBFD uplink symbols, and SBFD flexible symbols.

[0110] The SBFD downlink symbol can be understood as a downlink symbol configured to allow SBFD operation. Therefore, the SBFD downlink symbol can support downlink transmission and uplink transmission.

[0111] For example, the network may configure a portion of uplink subbands in the frequency domain of downlink symbols in the original time slot through network signaling, so that the downlink symbols can support uplink transmission and downlink transmission, thereby configuring the SBFD operation.

[0112] The SBFD uplink symbol can be understood as an uplink symbol configured to allow SBFD operation. Therefore, the SBFD uplink symbol can support uplink transmission and downlink transmission.

[0113] For example, the network may configure a portion of downlink subbands in the frequency domain of the uplink symbol in the original time slot through network signaling, so that the uplink symbol can support uplink transmission and downlink transmission, thereby configuring the SBFD operation.

[0114] The SBFD flexible symbol can be understood as a flexible symbol configured to allow SBFD operation. Therefore, the SBFD flexible symbol can be configured by the network to support uplink transmission and downlink transmission, that is, to support uplink and downlink transmission at the same time.

[0115] For example, the network may configure a portion of uplink subbands and a portion of downlink subbands in the frequency domain of the flexible symbol in the original time slot through network signaling, so that the flexible symbol can support uplink transmission and downlink transmission, thereby configuring the SBFD operation.

[0116] 2)SSB

[0117]

describe

[0118] Compared with LTE, the configuration of SSB in NR in time and frequency domain is more flexible, and therefore more complex. Since NR can be deployed in high-frequency bands, the network needs to use multiple-input multiple-output (MIMO) to enhance coverage. However, the antenna radiation pattern of MIMO is a very narrow beam, and a single beam is difficult to cover the entire cell.

[0119] In addition, due to hardware limitations, the network is often unable to send multiple beams at the same time to cover the entire cell, so NR can achieve coverage of the entire cell through beam scanning, that is, the network sends beams in different directions at multiple times to cover the entire cell. Among them, each beam needs to be configured with a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH), and they need to be sent simultaneously to achieve downlink synchronization. For this reason, PSS, SSS and PBCH are collectively referred to as SSB in NR.

[0120] The SSB can be located in a downlink symbol or a flexible symbol. When the SSB is located in a flexible symbol, the flexible symbol cannot be used to send uplink data or uplink signals, and the flexible symbol cannot be set to the uplink direction by higher layer signaling or DCI.

[0121] Unlike the fixed 5ms transmission period of PSS / SSS in LTE, the transmission period of SSB in NR can vary from 5ms to 160ms. In NR, the SSB period can be configured to 5ms, 10ms, 20ms, 40ms, 80ms and 160ms, which can be configured by the high-level parameter ssb-periodicityServingCell.

[0122] In the time domain, each SSB can be composed of 4 consecutive OFDM symbols, and the OFDM symbols are numbered in ascending order from 0 to 3 within the SSB; in the frequency domain, each SSB can be composed of 240 consecutive subcarriers (i.e., 20 RBs), and the subcarriers are numbered in ascending order from 0 to 239 within the SSB.

[0123] In NR, SSB is transmitted by beam scanning, that is, SSB is transmitted on different beams by time division multiplexing. In this regard, the set of SSBs in a beam scan can be called an SSB burst set (SS Burst Set). Among them, the SSB period can refer to the transmission period of the SSB burst set. However, within each SSB period, the SSB burst set may be limited to a time interval of 5ms, either within the first half frame (each half frame is 5ms) of each system frame (each system frame is 10ms), or within the second half frame of each system frame.

[0124] The maximum number of SSBs in each SSB burst set (given by L maxIt may vary depending on the frequency band. Among them, the SSB pattern can be used to determine the possible candidate positions of SSBs within each SSB burst set (with a length of half a frame) and the maximum number of SSBs L max , but the number of SSBs in the actually transmitted SSB subset can be less than L max .

[0125] The actually transmitted SSB subset can be determined within the SSB burst set by the higher-layer parameter ssb-PositionsInBurst (SSB positions within the burst) in System Information Block 1 (SIB1) or the higher-layer parameter ssb-PositionsInBurst in UE-specific RRC signaling

[0126]

Higher-layer parameter ssb-PositionsInBurst in SIB1

[0127] The higher-layer parameter ssb-PositionsInBurst in SIB1 can be used to indicate to the terminal device the SSB subset transmitted within an SSB burst set. Among them, the higher-layer parameter ssb-PositionsInBurst in SIB1 can be defined as follows:

[0128]

[0129] inOneGroup (within one group) field: It can represent a bitmap with a length of 8 bits and can be used to indicate which SSBs are transmitted within the SSB burst set. Among them, if the bit in this bitmap is 0, it means the SSB is not transmitted; if the bit is 1, it means the SSB is transmitted. Specifically as follows:

[0130] For frequency band fc ≤ 3 GHz: The maximum number of SSBs within the SSB burst set is 4, that is, L max = 4, so 4 bits are sufficient to indicate which SSBs are transmitted. In this case, only the lower (left) 4 bits in inOneGroup are valid

[0131] For frequency band 3 GHz < fc ≤ 6 GHz: The maximum number of SSBs within the SSB burst set is 8, that is, L max = 8, so 8 bits are sufficient to indicate which SSBs are transmitted

[0132] For frequency band fc > 6 GHz: The maximum number of SSBs within the SSB burst set is 64, that is, L max = 64. In this case, 64 SSBs can be divided into 8 SSB groups, and an additional groupPresence (group presence) field is required to indicate which SSB groups are transmitted

[0133] groupPresence field: can represent an 8-bit bitmap, where the bits in the bitmap correspond one-to-one to the SSB groups, and can be used to indicate which SSB groups are transmitted. Among them, the lowest (left) bit of groupPresence represents the SSBs with indexes 0 to 7 (i.e. the first SSB group, or the SSB group with index 0), the second lowest (left) bit represents the SSBs with indexes 8 to 15 (i.e. the second SSB group, or the SSB group with index 1), and so on. Among them, if the bit is 0, it means that the SSB group is not transmitted; if the bit is 1, it means that the SSB group is transmitted. Finally, inOneGroup is used to indicate which SSBs in the transmitted SSB group are transmitted.

[0134] For example, with L max =8 as an example, if inOneGroup = {11111111}, then SSBs 0 to 7 in the SSB burst set are all transmitted. At this time, the transmitted SSB subset includes SSBs with indexes 0 to 7.

[0135] For example, L max =64 as an example, groupPresence = {10100000}, and inOneGroup = {11000000}, then in the 8 SSB groups divided by the 64 SSBs in the SSB burst set, the first and second SSBs in the SSB groups with indexes of 0 and 2 (the corresponding SSB sets are {0,1,2,3,4,5,6,7} and {16,17,18,19,20,21,22,23} respectively) are transmitted, that is, the SSBs with indexes of 0, 1, 16, and 17 are transmitted. At this time, the transmitted SSB subset includes the SSBs with indexes of 0, 1, 16, and 17.

[0136] [High-layer parameter ssb-PositionsInBurst in UE-specific RRC signaling]

[0137] The high-level parameter ssb-PositionsInBurst in the UE-specific RRC signaling can be used to indicate to the terminal device the SSB subset transmitted within an SSB burst set. The high-level parameter ssb-PositionsInBurst in the UE-specific RRC signaling can be defined as follows:

[0138]

[0139]

[0140] Frequency band fc≤3GHz: The maximum number of SSBs in an SSB burst set is 4, i.e. L max =4, so a 4-bit shortBitmap is used to indicate it.

[0141] Frequency band 3 GHz < fc ≤ 6 GHz: The maximum number of SSBs in an SSB burst set is 8, i.e., L max = 8, so a mediumBitmap with a length of 8 bits is used to indicate.

[0142] Frequency band fc > 6 GHz: The maximum number of SSBs in an SSB burst set is 64, i.e., L max = 64, so a longBitmap with a length of 64 bits is used to indicate.

[0143]

Determine the SSB in the transmitted SSB subset

[0144] It should be noted that this application needs to determine the SSB in the transmitted SSB subset, and perform uplink transmission or uplink reception according to the resource configuration of the determined SSB and SBFB, so as to study the impact of the SSB on the uplink transmission or uplink reception of SBFD in the configuration of SSB and SBFD, in order to enhance the uplink transmission. Next, this application can determine the SSB in the transmitted SSB subset in the following multiple ways to adapt to different scenario requirements and improve network flexibility.

[0145] Method 1:

[0146] In "Method 1", this application can introduce a configuration pattern, and determine the SSB in the transmitted SSB subset according to this configuration pattern, so as to implement the resource configuration of the SSB. Of course, the "configuration pattern" can also be described by other terms, and no specific restrictions are made on this.

[0147] Optionally, the configuration pattern can include a frequency domain resource bitmap, a time domain resource bitmap, and a periodic pattern bitmap. Of course, the "frequency domain resource bitmap", "time domain resource bitmap", and "periodic pattern bitmap" can also be described by other terms, and no specific restrictions are made on this.

[0148] ◆ Frequency domain resource bitmap

[0149] Each bit in the frequency domain resource bitmap can represent a frequency domain unit in the transmitted SSB subset. Among them, the bits in the frequency domain resource bitmap can correspond one-to-one with the frequency domain resources of the transmitted SSB subset.

[0150] Optionally, the frequency domain unit may include one of a subband, a resource block (RB), a resource element (RE), a subcarrier, etc., and there is no specific limitation on this. The subband here can be understood as a part of a sub-band divided from a bandwidth, and the bandwidth can be a bandwidth part (BWP).

[0151] For example, each bit in the frequency domain resource bitmap may represent one or more RBs, REs or subcarriers. In this way, the present application may configure the frequency domain resources of SSB at the RB level, RE level or subcarrier level (i.e., with a smaller granularity).

[0152] In specific implementation, if the first bit (which can be regarded as a certain bit) in the frequency domain resource bitmap is the target value, it means that SSB uses the frequency domain unit represented by the first bit; and / or, if the first bit is not the target value, it means that SSB does not use the frequency domain unit represented by the first bit.

[0153] The target value can be 1 or 0.

[0154] In this way, the present application can determine which frequency domain units are used in the frequency domain resources of the transmitted SSB subset according to the value of each bit in the frequency domain resource bitmap, thereby determining the SSB from the transmitted SSB subset and configuring the frequency domain resources of the SSB.

[0155] ◆Time domain resource bitmap

[0156] Each bit in the time domain resource bitmap may represent a time domain unit of the transmitted SSB subset, wherein the bits in the time domain resource bitmap may correspond one-to-one to the time domain resources of the transmitted SSB subset.

[0157] Optionally, the time domain unit may include one of a subframe, a time slot, a symbol, a mini time slot, etc., without specific limitation.

[0158] For example, each bit in the time domain resource bitmap may represent one or more symbols. In this way, the present application can configure the time domain resources of SSB at the symbol level (ie, with a smaller granularity).

[0159] In specific implementation, if the second bit (which can be regarded as a certain bit) in the time domain resource bitmap is the target value, it means that SSB uses the time domain unit represented by the second bit; and / or, if the second bit is not the target value, it means that SSB does not use the time domain unit represented by the second bit.

[0160] The target value can be 1 or 0.

[0161] In this way, the present application can determine which time domain units are used in the time domain resources of the transmitted SSB subset according to the value of each bit in the time domain resource bitmap, thereby determining the SSB from the transmitted SSB subset and configuring the time domain resources of the SSB.

[0162] ◆Periodic pattern bitmap

[0163] Each bit in the periodic pattern bitmap may be used to indicate whether the time domain resource bitmap is effective.

[0164] In specific implementation, if the third bit (which can be regarded as a certain bit) in the periodic pattern bitmap is the target value, it indicates that the time domain resource bitmap is effective; and / or, if the third bit is not the target value, it indicates that the time domain resource bitmap is not effective.

[0165] In this way, the time domain resources of SSB are flexibly configured through the periodic pattern bitmap.

[0166] Method 2:

[0167] Different from "method 1" which determines the SSB at the granularity of time-frequency resources, the present application can also determine the SSB in the transmitted SSB subset by indicating the SSB index.

[0168] Based on this, in "Method 2", in order to indicate the SSB index, the present application may introduce a bitmap, and the bits in the bitmap correspond one-to-one to the SSB index (index) in the transmitted SSB subset. Of course, "bitmap" may also be described using other terms, and there is no specific limitation on this.

[0169] That is, the lowest (left) bit of the bitmap corresponds to the first SSB (ie, the SSB with index 0), the second lowest (left) bit corresponds to the second SSB (ie, the SSB with index 1), and so on.

[0170] In this way, the bitmap can be used to indicate which SSBs are selected in the transmitted SSB subset.

[0171] In a specific implementation, if the bit in the bitmap is the target value, it means that the SSB corresponding to the bit is selected; and / or, if the bit in the bitmap is not the target value, it means that the SSB group corresponding to the bit is not selected.

[0172] For example, with L max=8 as an example, if inOneGroup = {11111111}, then SSBs 0 to 7 in the SSB burst set are all transmitted. At this time, the transmitted SSB subset includes SSBs with indexes 0 to 7. Then, the network configures an 8-bit bitmap, and the bits in the bitmap correspond one-to-one to the SSB indexes in the transmitted SSB subset. If the bitmap is "10000001", the SSBs with indexes 0 and 7 in the transmitted SSB subset are selected for subsequent uplink transmission or uplink reception based on the resource configuration of these two SSBs and SBFD.

[0173] It can be seen that "Method 2" can determine the SSB in the transmitted SSB subset by indicating the SSB index, so as to configure the resources of the SSB.

[0174] Method 3:

[0175] Since the number of SSBs in the transmitted SSB subset may be large, the length of the bitmap in "Method 2" may be long, thereby increasing the signaling overhead. Therefore, the present application can also divide the SSBs in the transmitted SSB subset to obtain multiple SSB groups, and then indicate the SSB group that needs to be selected, and finally indicate the SSB in the selected SSB group.

[0176] Based on this, in "Mode 3", the present application can introduce multiple bitmaps, namely a first bitmap and a second bitmap. Among them, the bits in the first bitmap correspond one-to-one to the SSB groups divided by the transmitted SSB subset, and the second bitmap corresponds one-to-one to the SSB index in the SSB group divided by the transmitted SSB subset. Of course, the "first bitmap" and the "second bitmap" can also be described by other terms, without specific limitation.

[0177] That is, the lowest (left) bit of the first bitmap corresponds to the first SSB group (i.e., the SSB group with index 0), the second lowest (left) bit corresponds to the second SSB group (i.e., the SSB group with index 1), and so on.

[0178] The lowest (left) bit of the second bitmap corresponds to the first SSB in the SSB group (ie, the SSB with index 0), the second lowest (left) bit corresponds to the second SSB in the SSB group (ie, the SSB with index 1), and so on.

[0179] In this way, the first bitmap can be used to indicate which SSB groups are selected, and the second bitmap can be used to indicate which SSBs in the selected SSB groups are selected.

[0180] In a specific implementation, if the bit in the first bitmap is the target value, it means that the SSB group corresponding to the bit is selected; and / or, if the bit in the first bitmap is not the target value, it means that the SSB group corresponding to the bit is not selected.

[0181] If the bit in the second bitmap is the target value, it means that the SSB corresponding to the bit in the selected SSB group is selected; and / or, if the bit in the second bitmap is not the target value, it means that the SSB corresponding to the bit in the selected SSB group is not selected.

[0182] For example, with L max =8 as an example, if inOneGroup = {11111111}, then SSBs 0 to 7 in the SSB burst set are all transmitted. At this time, the transmitted SSB subset includes SSBs with indexes 0 to 7. Then, the transmitted SSB subset is divided into 4 SSB groups, namely {SSB0, SSB1}, {SSB2, SSB3}, {SSB4, SSB5} and {SSB6, SSB7}. Finally, the network configures a first bitmap of 4 bits and a second bitmap of 2 bits. If the first bitmap is "1000" and the second bitmap is "11", the SSBs with indexes 0 and 1 in {SSB0, SSB1} are selected, that is, the SSBs with indexes 0 and 7 in the transmitted SSB subset are selected, so that uplink transmission or uplink reception can be performed later according to the resource configuration of these two SSBs and SBFD.

[0183] It can be seen that "Method 3" can determine the SSB in the transmitted SSB subset according to the first bitmap and the second bitmap at the granularity of the SSB index, which can not only save signaling overhead, but also realize the configuration of SSB resources.

[0184] 3) Resource allocation of SSB and SBFD

[0185] [Relationship between SSB resources and SBFD resources]

[0186] In the configuration of SBFD and SSB, there may be a certain relationship between the SSB resources configured by the network and the SBFD resources, and this relationship may affect whether the SBFD uplink transmission or uplink reception can be performed.

[0187] This is because, since the resources of SSB cannot be used for uplink transmission, when there is a non-overlap relationship between the resources of SSB and the SBFD uplink subband, that is, the resources of SSB and the SBFD uplink subband are non-overlapping, SSB may not affect the uplink transmission or uplink reception in the non-overlapping SBFD uplink subband, so that the non-overlapping SBFD uplink subband can be used for uplink transmission or uplink reception.

[0188] However, when there is an overlap between the SSB resources and the SBFD uplink subband, that is, the SSB resources overlap with the SBFD uplink subband, the SSB may affect the uplink transmission or uplink reception in the overlapping SBFD uplink subband, so that the overlapping SBFD uplink subband may not be used for uplink transmission or uplink reception.

[0189] The following describes the non-overlapping of SSB resources and the SBFD uplink subband and the overlapping of SSB resources and the SBFD uplink subband.

[0190] [SSB resources do not overlap with SBFD uplink subbands]

[0191] In the resource configuration of SSB and SBFD, some SBFD uplink subbands may be non-overlapping with the resources of SSB. For the convenience of description and distinction, the present application may refer to the non-overlapping SBFD uplink subband as the "first SBFD uplink subband".

[0192] Based on this, the resources of SSB do not overlap with the first SBFD uplink subband, which can be understood as that all the resources of SSB are outside the first SBFD uplink subband, and all or part of the resources of SSB are within the SBFD downlink subband.

[0193] In addition, the SSB resources are non-overlapping with the first SBFD uplink subband, which can also be understood as the SSB does not overlap with the first SBFD uplink subband in the frequency domain and / or the SSB does not overlap with the first SBFD uplink subband in the time domain.

[0194] That is, the resources of the SSB are non-overlapping with the first SBFD uplink subband, which may include that the frequency domain resources of the SSB are non-overlapping with the first SBFD uplink subband, and / or the time domain resources of the SSB are non-overlapping with the first SBFD uplink subband.

[0195] For example, Figure 3 As shown, time slot n includes multiple downlink symbols, and these downlink symbols only include downlink subbands; time slot n+1 includes multiple SBFD symbols, and these SBFD symbols include uplink subbands, downlink subbands and guard bands. At the same time, SSB is within the downlink subband of time slot n+1. Among them, Figure 3 (a) of FIG. 1 does not yet illustrate the first SBFD uplink subband, and Figure 3 (b) shows the first SBFD uplink subband.

[0196] In this way, since the resources of SSB do not overlap with the first SBFD uplink subband, the transmission of SSB will not affect the uplink transmission or uplink reception on the first SBFD uplink subband, so that the first SBFD uplink subband can be used for uplink transmission or uplink reception, or in other words, the first SBFD uplink subband is available for uplink transmission or uplink reception.

[0197] [SSB resources overlap with SBFD uplink subband]

[0198] In the resource configuration of SSB and SBFD, some SBFD uplink subbands may overlap with the resources of SSB. For the convenience of description and distinction, the present application may refer to the overlapping SBFD uplink subband as the "second SBFD uplink subband".

[0199] Based on this, the resources of SSB overlap with the second SBFD uplink subband, which can be understood as that all the resources of SSB are within the second SBFD uplink subband (ie, complete overlap), or part of the resources of SSB are within the second SBFD uplink subband (ie, partial overlap).

[0200] In addition, the SSB resources overlap with the second SBFD uplink subband, which can also be understood as the SSB overlaps with the second SBFD uplink subband in the frequency domain and / or the SSB overlaps with the second SBFD uplink subband in the time domain.

[0201] That is, the SSB resources overlap with the second SBFD uplink subband, which may include: the frequency domain resources of the SSB overlap with the second SBFD uplink subband, and / or the time domain resources of the SSB overlap with the second SBFD uplink subband.

[0202] It should be noted that the “overlap” mentioned here can be “partial overlap” or “complete overlap”, and examples are given below to illustrate this respectively.

[0203] For example, Figure 4 As shown, time slot n includes multiple downlink symbols, and these downlink symbols only include downlink subbands; time slot n+1 includes multiple SBFD symbols, and these SBFD symbols include uplink subbands, downlink subbands and guard bands. At the same time, SSB0 partially overlaps with the uplink subband of time slot n+1, while SSB1 completely overlaps with the uplink subband of time slot n+1. Among them, Figure 4 (a) of FIG. 1 does not yet illustrate the second SBFD uplink subband, and Figure 4 (b) shows the second SBFD uplink subband.

[0204] In this way, since the resources of SSB overlap with the second SBFD uplink subband, the transmission of SSB will affect the uplink transmission or uplink reception on the second SBFD uplink subband, making the second SBFD uplink subband unable to be used for uplink transmission or uplink reception, or in other words, the second SBFD uplink subband is unavailable for uplink transmission or uplink reception.

[0205] Optionally, the second SBFD uplink subband cannot be used for uplink transmission or uplink reception, which may include: the time domain unit where the second SBFD uplink subband is located cannot be used for uplink transmission or uplink reception, and the time domain unit may include one of a symbol, a time slot, a subframe, and a half frame.

[0206] For example, taking the time domain unit as a symbol, in the above Figure 4 In the example, the symbol where the second SBFD uplink subband in the time slot n+1 is located cannot be used for uplink transmission or uplink reception, while the remaining symbols in the time slot n+1 can be used for uplink transmission.

[0207] For another example, taking the time domain unit as a time slot, in the above Figure 4 In the example, the time slot n+1 where the second SBFD uplink subband is located cannot be used for uplink transmission or uplink reception.

[0208] In this way, it is avoided that the uplink transmission or uplink reception fails due to the use of the time domain unit where the second SBFD uplink subband is located for uplink transmission or uplink reception, thereby reducing the communication reliability.

[0209] 4) Uplink channel in SBFD uplink subband

[0210]

describe

[0211] It should be noted that the network may configure an uplink channel in the SBFD uplink subband, wherein the uplink channel here may include an uplink channel and a signal.

[0212] For example, the uplink channel may be a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), a physical downlink shared channel (PDSCH), a sounding reference signal (SRS), etc.

[0213] In addition, since the network may configure the uplink channel in different ways, the uplink channels configured by the network may be of different types.

[0214] For example, the network may use dynamic scheduling to configure the uplink channel, may use dynamic triggering to configure the uplink channel, may use semi-persistent scheduling (SPS) to configure the uplink channel, may use semi-static scheduling, may configure periodic uplink channels, etc. Among them, the present application may collectively refer to "semi-persistently scheduled uplink channels", "periodic uplink channels" and "semi-statically scheduled uplink channels" as "uplink channels configured by high-level signaling".

[0215] In summary, the type of uplink channel may include at least one of PRACH, dynamically scheduled PUSCH, dynamically scheduled PUCCH, dynamically triggered SRS, PUSCH configured by high-level signaling, PUCCH configured by high-level signaling, SRS configured by high-level signaling, etc.

[0216] Optionally, the uplink channels in the SBFD uplink sub-band may include an uplink channel in a first SBFD uplink sub-band and an uplink channel in a second SBFD uplink sub-band.

[0217] It should be noted that, since the second SBFD uplink subband cannot be used for uplink transmission or uplink reception, the uplink channels in the second SBFD uplink subband cannot be transmitted or received. However, for the uplink channels in the first SBFD uplink subband, although the first SBFD uplink subband can be used for uplink transmission or uplink reception, whether the uplink channels in the first SBFD uplink subband can be transmitted or received is discussed in detail below.

[0218]

Frequency domain interval

[0219] In the frequency domain, SSB will not overlap with the first SBFD uplink subband. Since SSB and the first SBFD uplink subband each have a lowest frequency domain unit and a highest frequency domain unit, there may be a certain frequency domain interval between the frequency domain resources of SSB and the first SBFD uplink subband.

[0220] That is, the frequency domain resources of the SSB are non-overlapping with the first SBFD uplink sub-band, which may include a frequency domain interval between the frequency domain resources of the SSB and the uplink channel in the first SBFD uplink sub-band.

[0221] For example, take the frequency domain interval between the lowest frequency domain unit of SSB and the highest frequency domain unit of the uplink channel as an example. Figure 5As shown, time slot n includes multiple downlink symbols, and these downlink symbols only include downlink subbands; time slot n+1 includes multiple SBFD symbols, and these SBFD symbols include uplink subbands, downlink subbands and guard bands. At the same time, SSB is within the downlink subband of time slot n+1. At this time, there is a frequency domain interval between the lowest frequency domain unit of SSB and the highest frequency domain unit of the uplink channel.

[0222] Optionally, the frequency domain interval can be the number of frequency domain units (such as the number of RBs, the number of REs, the number of subcarriers, etc.) between the lowest frequency domain unit of the SSB and the highest frequency domain unit of the uplink channel, or can be the number of frequency domain units (such as the number of RBs, the number of REs, the number of subcarriers, etc.) between the highest frequency domain unit of the SSB and the lowest frequency domain unit of the uplink channel.

[0223] It should be noted that the highest frequency domain unit can be understood as a frequency domain unit with a maximum index; the lowest frequency domain unit can be understood as a frequency domain unit with a minimum index.

[0224] For example, taking the frequency domain unit as subcarrier / RB / RE, an SSB can be composed of 240 consecutive subcarriers (i.e., 20 RBs or 240 REs), and the subcarriers / REs are numbered in ascending order from 0 to 239 in the SSB, and the RBs are numbered in ascending order from 0 to 19 in the SSB. At this time, the subcarrier / RE with index 0 is the lowest frequency domain unit of the SSB, and the subcarrier / RE with index 239 is the highest frequency domain unit of the SSB; the RB with index 0 is the lowest frequency domain unit of the SSB, and the RB with index 19 is the highest frequency domain unit of the SSB.

[0225] [Can the uplink channel in the first SBFD uplink subband be transmitted?]

[0226] In combination with the above, it can be seen that although the first SBFD uplink subband can be used for uplink transmission or uplink reception, whether the uplink channel in the first SBFD uplink subband can be transmitted or received still needs to be discussed in different situations. The present application can determine whether the uplink channel can be transmitted or received from the following multiple situations to adapt to different scenario requirements.

[0227] Scenario 1:

[0228] In "Case 1", since there is a frequency domain interval between the frequency domain resources of the SSB and the uplink channel in the first SBFD uplink subband, the present application can introduce a preset interval threshold corresponding to the uplink channel, and determine whether the uplink channel can be transmitted or received based on the size relationship between the frequency domain interval and the preset interval threshold corresponding to the uplink channel.

[0229] In a specific implementation, if the frequency domain interval is greater than or equal to the preset interval threshold corresponding to the uplink channel, the uplink channel can be transmitted; and / or, if the frequency domain interval is less than the preset interval threshold corresponding to the uplink channel, the uplink channel cannot be transmitted or received.

[0230] It should be noted that when the frequency domain interval is greater than or equal to the preset interval threshold, this indicates that there is a larger frequency domain interval between the SSB and the uplink channel. At this time, the downlink transmission of the SSB does not affect the uplink transmission. In this way, the present application considers that transmission or reception can be performed on the uplink channel.

[0231] Similarly, when the frequency domain interval is less than the preset interval threshold, it means that there is a small frequency domain interval between the SSB and the uplink channel. At this time, the downlink transmission of the SSB may affect the uplink transmission or uplink reception. In this way, the present application considers that it is not possible to transmit or receive in the uplink channel.

[0232] Optionally, the preset interval threshold corresponding to the uplink channel may be configured by the network, may be pre-configured, or may be stipulated by a protocol, and no specific limitation is imposed on this.

[0233] Optionally, since uplink channels have different types, and in order to ensure transmission, different types of uplink channels may have different transmission requirements and transmission capabilities, etc., the present application may configure different preset interval threshold values ​​for different types of uplink channels.

[0234] That is to say, different types of uplink channels correspond to different values ​​of the preset interval threshold.

[0235] In this way, the present application can configure the value of the corresponding preset interval threshold according to the uplink channel that actually needs to be transmitted, so as to meet different transmission requirements and transmission capabilities.

[0236] For example, the value of the preset interval threshold corresponding to the dynamically scheduled uplink channel may be greater than the value of the preset interval threshold corresponding to the uplink channel configured by the higher layer signaling.

[0237] For another example, the value of the preset interval threshold corresponding to the PRACH may be greater than that of the dynamically scheduled PUCCH.

[0238] Optionally, since uplink channels have different types, configuring different preset interval threshold values ​​for different types of uplink channels may increase the complexity of the network and increase the network burden. Therefore, in order to reduce the complexity of the network, the present application can configure the same preset interval threshold value for different types of uplink channels.

[0239] That is to say, the values ​​of the preset interval thresholds corresponding to different types of uplink channels are the same.

[0240] Scenario 2:

[0241] In "Scenario 2", since different types of uplink channels may have different transmission requirements and transmission capabilities, etc., and different types of uplink channels may have different network configurations / network requirements / network environments, etc., the present application can directly determine whether the uplink channel in the first SBFD uplink subband can be transmitted based on the type of the uplink channel.

[0242] For example, if the uplink channel is one of PRACH, dynamically scheduled PUSCH, dynamically scheduled PUCCH, and dynamically triggered SRS, the uplink channel can be transmitted; and / or, if the uplink channel is one of PUSCH configured by high-level signaling, PUCCH configured by high-level signaling, and SRS configured by high-level signaling, the uplink channel cannot be transmitted.

[0243] For another example, if the uplink channel is PRACH, the uplink channel can be transmitted; and / or, if the uplink channel is one of dynamically scheduled PUSCH, dynamically scheduled PUCCH, dynamically triggered SRS, PUSCH configured by high-level signaling, PUCCH configured by high-level signaling, and SRS configured by high-level signaling, the uplink channel cannot be transmitted.

[0244] For another example, if the uplink channel is PRACH, PUSCH configured by high-level signaling, PUCCH configured by high-level signaling, or SRS configured by high-level signaling, the uplink channel can be transmitted; and / or, if the uplink channel is one of dynamically scheduled PUSCH, dynamically scheduled PUCCH, and dynamically triggered SRS, the uplink channel cannot be transmitted.

[0245] In this way, the present application can dynamically adjust which types of uplink channels can be transmitted according to different network configurations / network states / network environments / network requirements, so as to improve network flexibility.

[0246] Scenario 3:

[0247] The network may be configured with different types of SSBs, and different types of SSBs may have different network capabilities, etc., and different types of SSBs may have different network configurations / network requirements / network environments, etc.

[0248] Optionally, the types of SSB may include cell defining SSB (Cell Defining SSB, CD-SSB for short) and non-cell defining SSB (Non-Cell Defining SSB, NCD-SSB).

[0249] It should be noted that when SSB is associated with the remaining minimum SI (RMSI), SSB is called CD-SSB. CD-SSB can define a cell, including the physical cell identity (PCI), RMSI, initial BWP, etc., while NCD-SSB can be used for channel measurement, etc.

[0250] Based on this, the present application can determine whether the uplink channel in the first SBFD uplink subband can be transmitted according to the type of SSB, and dynamically adjust which types of SSB can affect whether the uplink channel can be transmitted or not according to different network configurations / network status / network environment / network requirements, so as to improve network flexibility.

[0251] Optionally, if the SSB is NCD-SSB, the uplink channel can be transmitted; and / or, if the SSB is CD-SSB, the uplink channel cannot be transmitted.

[0252] This is because, compared with NCD-SSB, CD-SSB involves the definition of cells, which is relatively important for the network and terminal devices. At this time, in the configuration of CD-SSB and SBFD, CD-SSB affects the uplink channel and cannot be transmitted.

[0253] Optionally, if the SSB is NCD-SSB, the uplink channel cannot be transmitted; and / or, if the SSB is CD-SSB, the uplink channel can be transmitted.

[0254] This is because, compared to NCD-SSB, although CD-SSB involves the definition of cells, the present application can determine based on network configuration / network status / network environment / network requirements that CD-SSB affects the uplink channel for transmission, while NCD-SSB affects the uplink channel for transmission.

[0255] Optionally, if the SSB is CD-SSB, whether the uplink channel can be transmitted is determined by the frequency domain interval between the frequency domain resources of the CD-SSB and the uplink channel.

[0256] It should be noted that, in combination with the above-mentioned "frequency domain interval" and the contents of "Case 1", there can be a certain frequency domain interval between the frequency domain resources of CD-SSB and the uplink channel in the first SBFD subband. Therefore, the present application can determine whether the uplink channel can be transmitted based on the size relationship between the frequency domain interval and the preset interval threshold corresponding to the uplink channel.

[0257] In specific implementation, if the frequency domain interval is greater than or equal to the preset interval threshold corresponding to the uplink channel, the uplink channel can be transmitted; and / or, if the frequency domain interval is less than the preset interval threshold corresponding to the uplink channel, the uplink channel cannot be transmitted.

[0258] It should be noted that this part of the content can be found in the description of "Scenario 1" above, and will not be repeated here.

[0259] Optionally, if the SSB is NCD-SSB, whether the uplink channel can be transmitted is determined by the frequency domain interval between the frequency domain resources of the NCD-SSB and the uplink channel.

[0260] It should be noted that, in combination with the above-mentioned "frequency domain interval" and the contents of "Case 1", there can be a certain frequency domain interval between the frequency domain resources of NCD-SSB and the uplink channel in the first SBFD subband. Therefore, the present application can determine whether the uplink channel can be transmitted based on the size relationship between the frequency domain interval and the preset interval threshold corresponding to the uplink channel.

[0261] In specific implementation, if the frequency domain interval is greater than or equal to the preset interval threshold corresponding to the uplink channel, the uplink channel can be transmitted; and / or, if the frequency domain interval is less than the preset interval threshold corresponding to the uplink channel, the uplink channel cannot be transmitted.

[0262] It should be noted that this part of the content can be found in the description of "Scenario 1" above, and will not be repeated here.

[0263] Scenario 4:

[0264] In "Case 4", the terminal device can measure the channel according to SSB to obtain the signal quality (also called channel quality), which can be used as preliminary information about the channel status, received power, multipath characteristics, etc., to help optimize the performance of the communication system.

[0265] Based on this, from the perspective of measuring the channel, the present application can introduce a preset signal quality threshold, and determine whether the uplink channel can be transmitted based on the size relationship between the signal quality measured by SSB and the preset signal quality threshold. In this way, the present application can determine whether the uplink channel can be transmitted from the perspective of measuring the channel.

[0266] In specific implementation, whether the uplink channel in the first SBFD uplink subband can be transmitted is determined by the signal quality measured by SSB, which may include: if the signal quality measured by SSB is greater than or equal to a preset signal quality threshold, the uplink channel can be transmitted; and / or, if the signal quality measured by SSB is less than the preset signal quality threshold, the uplink channel cannot be transmitted.

[0267] It should be noted that, since the downlink channel is symmetrical with the uplink channel, the channel state, received power and multipath characteristics of the downlink channel can be used to reflect the channel quality of the uplink channel. When the signal quality measured by SSB is greater than or equal to the preset signal quality threshold, this indicates that the channel quality of the downlink channel is very good, or can meet the normal downlink communication quality requirements, thereby reflecting that the channel quality of the uplink channel may also be very good, or can also meet the normal uplink communication quality requirements. In this way, the present application considers that transmission can be performed on the uplink channel.

[0268] Similarly, when the signal quality measured by SSB is less than the preset signal quality threshold, this indicates that the channel quality of the downlink channel may be very good, and reflects that the channel quality of the uplink channel may also be poor, or cannot meet the normal downlink communication quality requirements, thereby reflecting that the channel quality of the uplink channel may also be poor, or cannot meet the normal uplink communication quality requirements. In this way, the present application considers that transmission cannot be performed on the uplink channel.

[0269] Optionally, the signal quality measured by SSB may include at least one of reference signal received quality (Reference Singnal Received Quality, RSRQ), reference signal received power (Reference Singnal Received Power, RSRP), received signal strength indication (Received Singnal Strengthen Indicator, RSSI), signal to interference & noise ratio (Signal to Interference & Noise Ratio, SINR), etc.

[0270] Optionally, the preset signal quality threshold may be network configured, preconfigured, or specified by a protocol, and there is no specific limitation on this.

[0271] 3. An example of an uplink transmission method

[0272]

describe

[0273] In combination with the above content, an uplink transmission method of an embodiment of the present application is introduced as an example below. It should be noted that the method can be applied to a terminal device. Among them, the terminal device can be a chip, a chip module or a communication module, etc., and the network device can be a chip, a chip module or a communication module, etc.

[0274] like Figure 6 FIG. 1 is a flow chart of an uplink transmission method according to an embodiment of the present application, which specifically includes the following steps:

[0275] S601, perform uplink transmission according to the resource configuration of synchronization signal block SSB and sub-band full-duplex SBFD. It should be noted that "SSB", "SBFD", etc. can be found in the above content, which will not be described in detail.

[0276] It can be seen that since the network will configure SSB resources and SBFD resources, and there may be a certain relationship between the SSB resources and the SBFD resources, and this relationship may have a certain impact on whether the SBFD uplink transmission can be performed, the present application can perform uplink transmission according to the resource configuration of SSB and SBFD, so as to ensure uplink transmission as much as possible in the configuration of SSB and SBFD and achieve uplink enhancement.

[0277] Some possible implementations

[0278] In combination with the above content, some possible implementation methods are described below. For other methods not described, please refer to the above content for details, and no further elaboration will be given.

[0279] In some possible implementations, resource configuration of SSB and SBFD includes:

[0280] The resources of the SSB do not overlap with the first SBFD uplink subband, and / or the resources of the SSB overlap with the second SBFD uplink subband.

[0281] It should be noted that, combined with the content in the above “3) Resource configuration of SSB and SBFD”, since the resources of SSB cannot be used for uplink transmission, when there is a non-overlapping relationship between the resources of SSB and the SBFD uplink subband, that is, the resources of SSB and the SBFD uplink subband are non-overlapping, SSB may not affect the uplink transmission in the non-overlapping SBFD uplink subband, so that the non-overlapping SBFD uplink subband can be used for uplink transmission.

[0282] However, when there is an overlapping relationship between SSB resources and the SBFD uplink subband, that is, SSB resources overlap with the SBFD uplink subband, SSB may affect the uplink transmission in the overlapping SBFD uplink subband, so that the overlapping SBFD uplink subband may not be used for uplink transmission.

[0283] Therefore, in the resource configuration of SSB and SBFD, some SBFD uplink subbands may not overlap with the resources of SSB, while some SBFD uplink subbands may overlap with the resources of SSB.

[0284] In some possible implementations, the resources of the SSB are non-overlapping with the first SBFD uplink subband, including:

[0285] The frequency domain resources of the SSB do not overlap with the first SBFD uplink subband, and / or the time domain resources of the SSB do not overlap with the first SBFD uplink subband.

[0286] It should be noted that, combined with the content of "[SSB resources and SBFD uplink subband are non-overlapping]", it can be seen that this will not be repeated.

[0287] In some possible implementations, the first SBFD uplink subband can be used for uplink transmission.

[0288] It should be noted that, combined with the above content of “[SSB resources do not overlap with the SBFD uplink subband]”, since the SSB resources do not overlap with the first SBFD uplink subband, the transmission of SSB will not affect the uplink transmission on the first SBFD uplink subband, so that the first SBFD uplink subband can be used for uplink transmission, or the first SBFD uplink subband is available for uplink transmission.

[0289] In some possible implementations, the frequency domain resources of the SSB are non-overlapping with the first SBFD uplink subband, including:

[0290] There is a frequency domain interval between the frequency domain resources of the SSB and the uplink channel in the first SBFD uplink subband.

[0291] It should be noted that, combined with the content in the above "

Frequency Domain Interval

[0292] In some possible implementations, if the frequency domain interval is greater than or equal to a preset interval threshold corresponding to the uplink channel, the uplink channel can be transmitted; and / or,

[0293] If the frequency domain interval is smaller than the preset interval threshold corresponding to the uplink channel, the uplink channel cannot be transmitted.

[0294] It should be noted that, in combination with the content in the above "Case 1", since there is a frequency domain interval between the frequency domain resources of SSB and the uplink channel in the first SBFD uplink sub-band, the present application can introduce a preset interval threshold corresponding to the uplink channel, and determine whether the uplink channel can be transmitted based on the size relationship between the frequency domain interval and the preset interval threshold corresponding to the uplink channel.

[0295] In some possible implementations, the preset interval thresholds corresponding to different types of uplink channels have the same value; or,

[0296] Different types of uplink channels have different values ​​for the preset interval thresholds.

[0297] It should be noted that, in combination with the content in the above "Scenario 1", the present application can configure the value of the corresponding preset interval threshold according to the uplink channel that actually needs to be transmitted, so as to meet different transmission requirements and transmission capabilities.

[0298] Since uplink channels have different types, configuring different preset interval threshold values ​​for different types of uplink channels may increase the complexity of the network and increase the network burden. Therefore, in order to reduce the complexity of the network, the present application can configure the same preset interval threshold value for different types of uplink channels.

[0299] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be transmitted is determined by the type of the uplink channel.

[0300] It should be noted that, in combination with the content in the above "Scenario 2", since different types of uplink channels may have different transmission requirements and transmission capabilities, and different types of uplink channels may have different network configurations / network requirements / network environments, the present application can directly determine whether the uplink channel in the first SBFD uplink subband can be transmitted based on the type of the uplink channel.

[0301] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be transmitted is determined by the type of the uplink channel, including:

[0302] If the uplink channel is one of a physical random access channel PRACH, a dynamically scheduled physical uplink shared channel PUSCH, a dynamically scheduled physical uplink control channel PUCCH, and a dynamically triggered sounding reference signal SRS, the uplink channel can be transmitted; and / or,

[0303] If the uplink channel is one of the PUSCH configured by higher layer signaling, the PUCCH configured by higher layer signaling, and the SRS configured by higher layer signaling, the uplink channel cannot be transmitted.

[0304] It should be noted that, combined with the content in the above “Scenario 2”, it can be seen that this will not be elaborated on.

[0305] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be transmitted is determined by the type of SSB.

[0306] It should be noted that, in combination with the content in the above-mentioned "Scenario 3", the present application can determine whether the uplink channel in the first SBFD uplink subband can be transmitted according to the type of SSB, and dynamically adjust which types of SSB can affect whether the uplink channel can be transmitted or not according to different network configurations / network status / network environment / network requirements, so as to improve network flexibility.

[0307] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be transmitted is determined by the type of SSB, including:

[0308] If the SSB is a non-cell defined NCD-SSB, the uplink channel can be transmitted; and / or,

[0309] If the SSB is defined as CD-SSB for the cell, whether the uplink channel can be transmitted is determined by the frequency domain interval between the frequency domain resources of the CD-SSB and the uplink channel; otherwise, if the SSB is CD-SSB, the uplink channel cannot be transmitted.

[0310] It should be noted that, combined with the content in the above “Scenario 3”, it can be seen that this will not be elaborated on.

[0311] In some possible implementations, whether the uplink channel can be transmitted is determined by the frequency domain spacing between the frequency domain resources of the CD-SSB and the uplink channel, including:

[0312] If the frequency domain interval is greater than or equal to the preset interval threshold corresponding to the uplink channel, the uplink channel can be transmitted; and / or,

[0313] If the frequency domain interval is smaller than the preset interval threshold corresponding to the uplink channel, the uplink channel cannot be transmitted.

[0314] It should be noted that, combined with the content in the above “Scenario 3”, it can be seen that this will not be elaborated on.

[0315] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be transmitted is determined by the signal quality obtained by SSB measurement.

[0316] It should be noted that, in combination with the content in the above "Case 4", the signal quality measured by SSB can be used as preliminary information about channel status, received power, and multipath characteristics, thereby helping to optimize the performance of the communication system. Therefore, from the perspective of measuring the channel, the present application can introduce a preset signal quality threshold, and determine whether the uplink channel can be transmitted based on the relationship between the signal quality measured by SSB and the preset signal quality threshold. In this way, the present application can determine whether the uplink channel can be transmitted from the perspective of measuring the channel.

[0317] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be transmitted is determined by the signal quality measured by SSB, including:

[0318] If the signal quality measured by the SSB is greater than or equal to the preset signal quality threshold, the uplink channel can be transmitted; and / or,

[0319] If the signal quality measured by the SSB is less than the preset signal quality threshold, the uplink channel cannot be transmitted.

[0320] It should be noted that, combined with the content in the above “Scenario 4”, it can be seen that this will not be elaborated on.

[0321] In some possible implementations, the resources of the SSB overlap with the second SBFD uplink subband, including:

[0322] The frequency domain resources of SSB overlap with the second SBFD uplink subband, and / or the time domain resources of SSB overlap with the second SBFD uplink subband.

[0323] It should be noted that, combined with the content of "[SSB resources overlap with the SBFD uplink subband]", it can be seen that this will not be repeated.

[0324] In some possible implementations, the second SBFD uplink subband cannot be used for uplink transmission.

[0325] It should be noted that, combined with the above content of “[SSB resources overlap with the SBFD uplink subband]”, since the SSB resources overlap with the second SBFD uplink subband, the SSB transmission will affect the uplink transmission on the second SBFD uplink subband, making the second SBFD uplink subband unusable for uplink transmission, or in other words, the second SBFD uplink subband is unavailable for uplink transmission.

[0326] In some possible implementations, the second SBFD uplink subband cannot be used for uplink transmission, including:

[0327] The time domain unit where the second SBFD uplink subband is located cannot be used for uplink transmission, and the time domain unit includes one of a symbol, a time slot, a subframe, and a half frame.

[0328] It should be noted that, combined with the content of "[SSB resources overlap with the SBFD uplink subband]", it can be seen that this will not be repeated.

[0329] In some possible implementations, the SSB is determined in a subset of SSBs transmitted in an SSB burst set according to a configuration pattern, the configuration pattern including a frequency domain resource bitmap and / or a time domain resource bitmap;

[0330] Each bit in the frequency domain resource bitmap represents a frequency domain unit in the transmitted SSB subset;

[0331] Each bit in the time domain resource bitmap represents a time domain unit in the transmitted SSB subset.

[0332] It should be noted that, in combination with the content of the above-mentioned "Method 1", the present application can introduce a configuration pattern, and determine the SSB in the transmitted SSB subset according to the configuration pattern, so as to realize the resources for configuring the SSB.

[0333] In some possible implementations, if the first bit in the frequency domain resource bitmap is a target value, it means that the SSB uses the frequency domain unit represented by the first bit; and / or,

[0334] If the first bit is not the target value, it means that the SSB does not use the frequency domain unit represented by the first bit.

[0335] It should be noted that, combined with the content in the above “Method 1”, it can be seen that this will not be elaborated on.

[0336] In some possible implementations, if the second bit in the time domain resource bitmap is a target value, it indicates that the SSB uses the time domain unit represented by the second bit; and / or,

[0337] If the second bit is not the target value, it means that SSB does not use the time domain unit represented by the second bit.

[0338] It should be noted that, combined with the content in the above “Method 1”, it can be seen that this will not be elaborated on.

[0339] In some possible implementations, the configuration pattern further includes a periodic pattern bitmap;

[0340] Each bit in the periodic pattern bitmap is used to indicate whether the time domain resource bitmap is effective.

[0341] It should be noted that, combined with the content in the above “Method 1”, it can be seen that this will not be elaborated on.

[0342] In some possible implementations, if the third bit in the periodic pattern bitmap is a target value, it indicates that the time domain resource bitmap is effective; and / or,

[0343] If the third bit is not the target value, it indicates that the time domain resource bitmap is not effective.

[0344] It should be noted that, combined with the content in the above “Method 1”, it can be seen that this will not be elaborated on.

[0345] In some possible implementations, the SSB is determined in a subset of SSBs transmitted within an SSB burst set according to a bitmap, and the bits in the bitmap correspond one-to-one to the SSB indexes in the subset of SSBs transmitted.

[0346] It should be noted that, in combination with the content of the above-mentioned "Method 2", unlike "Method 1" which determines the SSB at the granularity of time-frequency resources, the present application can determine the SSB in the transmitted SSB subset by indicating the SSB index, and indicate the SSB index through a bitmap.

[0347] In some possible implementations, the SSB is determined in a subset of SSBs transmitted within an SSB burst set based on a first bitmap and a second bitmap;

[0348] The bits in the first bitmap correspond one-to-one to the SSB groups into which the transmitted SSB subset is divided;

[0349] The second bitmap corresponds one-to-one to the SSB index in the SSB group into which the transmitted SSB subset is divided.

[0350] It should be noted that, in combination with the content of the above-mentioned "Method 2", since the number of SSBs in the transmitted SSB subset may be large, the length of the bitmap in "Method 2" may be longer, thereby increasing the signaling overhead. Therefore, the present application can also divide the SSBs in the transmitted SSB subset to obtain multiple SSB groups, and then indicate the SSB group to be selected and the SSB in the selected SSB group respectively.

[0351] 4. An example of an uplink receiving method

[0352]

describe

[0353] In combination with the above content, an uplink receiving method of an embodiment of the present application is introduced as an example below. It should be noted that the method can be applied to a network device. The network device can be a chip, a chip module or a communication module.

[0354] like Figure 7 FIG. 1 is a flow chart of an uplink transmission method according to an embodiment of the present application, which specifically includes the following steps:

[0355] S701. Perform uplink reception according to the resource configuration of the synchronization signal block SSB and the sub-band full-duplex SBFD.

[0356] It should be noted that, for details of "SSB", "SBFD", etc., please refer to the above contents, which will not be elaborated on here.

[0357] It can be seen that since the network will configure SSB resources and SBFD resources, and there may be a certain relationship between the SSB resources and the SBFD resources, and this relationship may have a certain impact on whether SBFD uplink transmission can be performed, the present application can perform uplink transmission based on the resource configuration of SSB and SBFD, so as to ensure uplink reception as much as possible in the configuration of SSB and SBFD and achieve uplink enhancement.

[0358] Some possible implementations

[0359] In combination with the above content, some possible implementation methods are described below. For other methods not described, please refer to the above content for details, and no further elaboration will be given.

[0360] In some possible implementations, resource configuration of SSB and SBFD includes:

[0361] The resources of the SSB do not overlap with the first SBFD uplink subband, and / or the resources of the SSB overlap with the second SBFD uplink subband.

[0362] It should be noted that, combined with the content in the above “3) Resource configuration of SSB and SBFD”, since the resources of SSB cannot be used for uplink reception, when there is a non-overlapping relationship between the resources of SSB and the SBFD uplink subband, that is, the resources of SSB and the SBFD uplink subband are non-overlapping, SSB may not affect the uplink reception in the non-overlapping SBFD uplink subband, so that the non-overlapping SBFD uplink subband can be used for uplink reception.

[0363] However, when there is an overlapping relationship between SSB resources and the SBFD uplink subband, that is, SSB resources overlap with the SBFD uplink subband, SSB may affect the uplink reception in the overlapping SBFD uplink subband, so that the overlapping SBFD uplink subband may not be used for uplink reception.

[0364] Therefore, in the resource configuration of SSB and SBFD, some SBFD uplink subbands may not overlap with the resources of SSB, while some SBFD uplink subbands may overlap with the resources of SSB.

[0365] In some possible implementations, the resources of the SSB are non-overlapping with the first SBFD uplink subband, including:

[0366] The frequency domain resources of the SSB do not overlap with the first SBFD uplink subband, and / or the time domain resources of the SSB do not overlap with the first SBFD uplink subband.

[0367] It should be noted that, combined with the content of "[SSB resources and SBFD uplink subband are non-overlapping]", it can be seen that this will not be repeated.

[0368] In some possible implementations, the first SBFD uplink subband can be used for uplink reception.

[0369] It should be noted that, combined with the above content of “[SSB resources do not overlap with the SBFD uplink subband]”, since the SSB resources do not overlap with the first SBFD uplink subband, the transmission of SSB will not affect the uplink reception on the first SBFD uplink subband, so that the first SBFD uplink subband can be used for uplink reception, or the first SBFD uplink subband is available for uplink reception.

[0370] In some possible implementations, the frequency domain resources of the SSB are non-overlapping with the first SBFD uplink subband, including:

[0371] There is a frequency domain interval between the frequency domain resources of the SSB and the uplink channel in the first SBFD uplink subband.

[0372] It should be noted that, combined with the content in the above "

Frequency Domain Interval

[0373] In some possible implementations, if the frequency domain interval is greater than or equal to a preset interval threshold corresponding to the uplink channel, the uplink channel can be received; and / or,

[0374] If the frequency domain interval is smaller than the preset interval threshold corresponding to the uplink channel, the uplink channel cannot be received.

[0375] It should be noted that, in combination with the content in the above "Case 1", since there is a frequency domain interval between the frequency domain resources of SSB and the uplink channel in the first SBFD uplink sub-band, the present application can introduce a preset interval threshold corresponding to the uplink channel, and determine whether the uplink channel can be received based on the size relationship between the frequency domain interval and the preset interval threshold corresponding to the uplink channel.

[0376] In some possible implementations, the preset interval thresholds corresponding to different types of uplink channels have the same value; or,

[0377] Different types of uplink channels have different values ​​for the preset interval thresholds.

[0378] It should be noted that, in combination with the content in the above "Scenario 1", the present application can configure the value of the corresponding preset interval threshold according to the uplink channel actually received, so as to meet different transmission requirements and transmission capabilities.

[0379] Since uplink channels have different types, configuring different preset interval threshold values ​​for different types of uplink channels may increase the complexity of the network and increase the network burden. Therefore, in order to reduce the complexity of the network, the present application can configure the same preset interval threshold value for different types of uplink channels.

[0380] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be received is determined by the type of the uplink channel.

[0381] It should be noted that, in combination with the content in the above "Scenario 2", since different types of uplink channels may have different transmission requirements and transmission capabilities, etc., and different types of uplink channels may have different network configurations / network requirements / network environments, etc., the present application can directly determine whether the uplink channel in the first SBFD uplink subband can be received based on the type of the uplink channel.

[0382] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be received is determined by the type of the uplink channel, including:

[0383] If the uplink channel is one of a physical random access channel PRACH, a dynamically scheduled physical uplink shared channel PUSCH, a dynamically scheduled physical uplink control channel PUCCH, and a dynamically triggered sounding reference signal SRS, the uplink channel can be received; and / or,

[0384] If the uplink channel is one of the PUSCH configured by the higher layer signaling, the PUCCH configured by the higher layer signaling, and the SRS configured by the higher layer signaling, the uplink channel cannot be received.

[0385] It should be noted that, combined with the content in the above “Scenario 2”, it can be seen that this will not be elaborated on.

[0386] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be received is determined by the type of SSB.

[0387] It should be noted that, in combination with the content in the above-mentioned "Scenario 3", the present application can determine whether the uplink channel in the first SBFD uplink subband can be received according to the type of SSB, and dynamically adjust which types of SSB can affect whether the uplink channel can be received or not according to different network configurations / network status / network environment / network requirements, so as to improve network flexibility.

[0388] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be received is determined by the type of SSB, including:

[0389] If the SSB is a non-cell defined NCD-SSB, the uplink channel can be received; and / or,

[0390] If the SSB is cell-defined CD-SSB, whether the uplink channel can be received is determined by the frequency domain interval between the frequency domain resources of the CD-SSB and the uplink channel; otherwise, if the SSB is CD-SSB, the uplink channel cannot be received.

[0391] It should be noted that, combined with the content in the above “Scenario 3”, it can be seen that this will not be elaborated on.

[0392] In some possible implementations, whether the uplink channel can be received is determined by the frequency domain spacing between the frequency domain resources of the CD-SSB and the uplink channel, including:

[0393] If the frequency domain interval is greater than or equal to the preset interval threshold corresponding to the uplink channel, the uplink channel can be received; and / or,

[0394] If the frequency domain interval is smaller than the preset interval threshold corresponding to the uplink channel, the uplink channel cannot be received.

[0395] It should be noted that, combined with the content in the above “Scenario 3”, it can be seen that this will not be elaborated on.

[0396] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be received is determined by the signal quality obtained by SSB measurement.

[0397] It should be noted that, in combination with the content in the above "Case 4", the signal quality measured by SSB can be used as preliminary information about the channel state, receiving power and multipath characteristics, thereby helping to optimize the performance of the communication system. Therefore, from the perspective of measuring the channel, the present application can introduce a preset signal quality threshold, and determine whether the uplink channel can be received based on the relationship between the signal quality measured by SSB and the preset signal quality threshold. In this way, the present application can determine whether the uplink channel can be received from the perspective of measuring the channel.

[0398] In some possible implementations, whether the uplink channel in the first SBFD uplink subband can be received is determined by the signal quality measured by SSB, including:

[0399] If the signal quality measured by the SSB is greater than or equal to the preset signal quality threshold, the uplink channel can be received; and / or,

[0400] If the signal quality measured by the SSB is less than the preset signal quality threshold, the uplink channel cannot be received.

[0401] It should be noted that, combined with the content in the above “Scenario 4”, it can be seen that this will not be elaborated on.

[0402] In some possible implementations, the resources of the SSB overlap with the second SBFD uplink subband, including:

[0403] The frequency domain resources of SSB overlap with the second SBFD uplink subband, and / or the time domain resources of SSB overlap with the second SBFD uplink subband.

[0404] It should be noted that, combined with the content of "[SSB resources overlap with the SBFD uplink subband]", it can be seen that this will not be repeated.

[0405] In some possible implementations, the second SBFD uplink subband cannot be used for uplink reception.

[0406] It should be noted that, combined with the above content of “[SSB resources overlap with the SBFD uplink subband]”, since the SSB resources overlap with the second SBFD uplink subband, the transmission of SSB will affect the uplink reception on the second SBFD uplink subband, making the second SBFD uplink subband unusable for uplink reception, or in other words, the second SBFD uplink subband is unavailable for uplink reception.

[0407] In some possible implementations, the second SBFD uplink subband cannot be used for uplink reception, including:

[0408] The time domain unit where the second SBFD uplink subband is located cannot be used for uplink reception, and the time domain unit includes one of a symbol, a time slot, a subframe, and a half frame.

[0409] It should be noted that, combined with the content of "[SSB resources overlap with the SBFD uplink subband]", it can be seen that this will not be repeated.

[0410] In some possible implementations, the SSB is determined in a subset of SSBs transmitted in an SSB burst set according to a configuration pattern, the configuration pattern including a frequency domain resource bitmap and / or a time domain resource bitmap;

[0411] Each bit in the frequency domain resource bitmap represents a frequency domain unit in the transmitted SSB subset;

[0412] Each bit in the time domain resource bitmap represents a time domain unit in the transmitted SSB subset.

[0413] It should be noted that, in combination with the content of the above-mentioned "Method 1", the present application can introduce a configuration pattern, and determine the SSB in the transmitted SSB subset according to the configuration pattern, so as to realize the resources for configuring the SSB.

[0414] In some possible implementations, if the first bit in the frequency domain resource bitmap is a target value, it means that the SSB uses the frequency domain unit represented by the first bit; and / or,

[0415] If the first bit is not the target value, it means that the SSB does not use the frequency domain unit represented by the first bit.

[0416] It should be noted that, combined with the content in the above “Method 1”, it can be seen that this will not be elaborated on.

[0417] In some possible implementations, if the second bit in the time domain resource bitmap is a target value, it indicates that the SSB uses the time domain unit represented by the second bit; and / or,

[0418] If the second bit is not the target value, it means that SSB does not use the time domain unit represented by the second bit.

[0419] It should be noted that, combined with the content in the above “Method 1”, it can be seen that this will not be elaborated on.

[0420] In some possible implementations, the configuration pattern further includes a periodic pattern bitmap;

[0421] Each bit in the periodic pattern bitmap is used to indicate whether the time domain resource bitmap is effective.

[0422] It should be noted that, combined with the content in the above “Method 1”, it can be seen that this will not be elaborated on.

[0423] In some possible implementations, if the third bit in the periodic pattern bitmap is a target value, it indicates that the time domain resource bitmap is effective; and / or,

[0424] If the third bit is not the target value, it indicates that the time domain resource bitmap is not effective.

[0425] It should be noted that, combined with the content in the above “Method 1”, it can be seen that this will not be elaborated on.

[0426] In some possible implementations, the SSB is determined in a subset of SSBs transmitted within an SSB burst set according to a bitmap, and the bits in the bitmap correspond one-to-one to the SSB indexes in the subset of SSBs transmitted.

[0427] It should be noted that, in combination with the content of the above-mentioned "Method 2", unlike "Method 1" which determines the SSB at the granularity of time-frequency resources, the present application can determine the SSB in the transmitted SSB subset by indicating the SSB index, and indicate the SSB index through a bitmap.

[0428] In some possible implementations, the SSB is determined in a subset of SSBs transmitted within an SSB burst set based on a first bitmap and a second bitmap;

[0429] The bits in the first bitmap correspond one-to-one to the SSB groups into which the transmitted SSB subset is divided;

[0430] The second bitmap corresponds one-to-one to the SSB index in the SSB group into which the transmitted SSB subset is divided.

[0431] It should be noted that, in combination with the content of the above-mentioned "Method 2", since the number of SSBs in the transmitted SSB subset may be large, the length of the bitmap in "Method 2" may be longer, thereby increasing the signaling overhead. Therefore, the present application can also divide the SSBs in the transmitted SSB subset to obtain multiple SSB groups, and then indicate the SSB group to be selected and the SSB in the selected SSB group respectively.

[0434] The above mainly introduces the scheme of the embodiment of the present application from the perspective of the method side. It is understandable that in order to realize the above functions, the terminal device includes a hardware structure and / or software module corresponding to each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiments disclosed in this document, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0435] The embodiment of the present application can divide the terminal device or network device into functional units according to the above method example. For example, each functional unit can be divided according to each function, or two or more functions can be integrated into one processing unit. The above integrated unit can be implemented in the form of hardware or in the form of a software program module. It should be noted that the division of units in the embodiment of the present application is schematic, which is only a logical function division, and there may be other division methods in actual implementation.

[0447] The transmission unit 801 is used to perform uplink transmission according to the resource configuration of the synchronization signal block SSB and the sub-band full-duplex SBFD.

[0448] It can be seen that since the network will configure SSB resources and SBFD resources, and there may be a certain relationship between the SSB resources and the SBFD resources, and this relationship may have a certain impact on whether the SBFD uplink transmission can be performed, the present application can perform uplink transmission according to the resource configuration of SSB and SBFD, so as to ensure uplink transmission as much as possible in the configuration of SSB and SBFD and achieve uplink enhancement.
