Description

Information sending method, information receiving method and device Technical Field

[0001] The present application relates to the field of communications. Background Art

[0002] As the SI (Study Item) of Rel-18, the application scenarios, simulation methods, and potential standardization impact of SubBand non-overlapping Full Duplex (SBFD) were preliminarily studied in Rel-18.

[0003] It should be noted that the above introduction to the technical background is merely for convenience, to provide a clear and complete description of the technical solutions of this application and to facilitate understanding by those skilled in the art. It should not be assumed that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of this application.

[0004] Summary of the Invention

[0005] In the upcoming Rel-19, SBFD will be formally standardized as a WI (Work Item). For SBFD, terminal devices can be configured with non-overlapping downlink subbands and uplink subbands in existing downlink timeslots (or symbols) or flexible timeslots (or symbols), making the timeslots (or symbols) SBFD timeslots (or symbols). Within the SBFD timeslots, terminal devices can send uplink information on the uplink subbands, or receive downlink information on the downlink subbands. That is, the terminal devices operate in half-duplex mode (receive only or transmit only), while the network equipment can operate in full-duplex mode (receive and transmit simultaneously). With SBFD, terminal devices can perform uplink transmissions within existing downlink timeslots or flexible timeslots, which is equivalent to increasing the time and frequency resources available for uplink transmission. This can improve the capacity and coverage of uplink transmissions and reduce the latency of uplink transmissions.

[0006] Figure 1 is a schematic diagram of time-frequency domain resources configured with SBFD subbands. As shown in Figure 1, a terminal device is configured with SBFD subbands. SBFD subbands include downlink subbands and uplink subbands. For example, the uplink subband is located between two downlink subbands in the frequency domain. The time slot in which an SBFD subband is located is called an SBFD time slot, and the symbol in which an SBFD subband is located is called an SBFD symbol. Other time slots (or symbols) are called non-SBFD time slots (or symbols). By configuring SBFD subbands in some time slots, some additional time slots can be used for uplink transmission, which helps to enhance uplink coverage, increase uplink capacity, and reduce uplink transmission latency.

[0007] The NR standard supports uplink control information (UCI) multiplexing on the PUSCH (Physical Uplink Shared Channel) for transmission. The number of coded modulation symbols per layer used for UCI transmission is determined by β and α. For example, the number of coded modulation symbols per layer used for UCI transmission is Q′ ACK Determine according to the following formula (1):

[0008] α is a scaling factor configured by higher layers, controlling the upper limit of the number of coded modulation symbols per layer for UCI transmission. β controls the ratio between the PUSCH bit rate (or code rate) and the UCI bit rate (or code rate). For definitions of other parameters, refer to section 6.3.2.4 of TS 38.212-i00.

[0009] Currently, how to reuse UCI in SBFD is still a problem that needs to be solved.

[0010] The inventors discovered that the uplink transmission scheduled by the network device (such as dynamic grant PUSCH or configured grant PUSCH) may be located in an SBFD time slot (or symbol) or a non-SBFD time slot (or symbol). The time-frequency resources available for uplink transmission in the SBFD time slot (or symbol) and the non-SBFD time slot (or symbol) are different in size. Therefore, different uplink transmissions scheduled by the network device may have time-frequency resources of different sizes, and the resources of the SBFD time slot (or symbol) are smaller than the resources of the non-SBFD time slot (or symbol). In addition, the interference environment in which the SBFD time slot (or symbol) and the non-SBFD time slot (or symbol) are located may be different. For example, the SBFD time slot (or symbol) may be subject to more severe interference, that is, the interference to the SBFD time slot (or symbol) is higher than the interference to the non-SBFD time slot (or symbol). The prior art determines the appropriate number of UCI REs (Resource Element) based on β. The UCI RE number thus determined may be appropriate for non-SBFD time slots (or symbols), but not appropriate for SBFD time slots (or symbols). For example, for SBFD time slots (or symbols) with fewer resources, the number of UCI REs determined thereby is too large, thereby affecting uplink data transmission performance and causing uplink data transmission failure. For example, for SBFD time slots (or symbols) with more severe interference, the number of UCI REs determined thereby is too small, thereby affecting UCI transmission performance and causing UCI transmission failure.

[0011] In order to solve one or more of the above problems, embodiments of the present application provide an information sending method, an information receiving method, and an apparatus.

[0056] The following describes various implementations of the present application in conjunction with the accompanying drawings. These implementations are merely illustrative and are not intended to limit the present application.

[0057] Embodiments of the first aspect

[0058] An embodiment of the present application provides a method for sending information, which is applied to a terminal device, such as the terminal device 102 in Figure 2.

[0059] In the embodiment of the present application, the number of coded modulation symbols per layer for UCI transmission may be replaced by the number of REs used for UCI transmission.

[0060] In the embodiment of the present application, “PUSCH is transmitted in an SBFD time slot” means “PUSCH is transmitted on an SBFD symbol in an SBFD time slot”; and “PUSCH is transmitted in a non-SBFD time slot” means “PUSCH is transmitted on a non-SBFD symbol in a non-SBFD time slot”.

[0061] In the embodiment of the present application, “PUSCH is transmitted in the SBFD time slot” can be replaced by “PUSCH is transmitted on the SBFD symbol”; “PUSCH is transmitted in the non-SBFD time slot” can be replaced by “PUSCH is transmitted on the non-SBFD symbol”.

[0062] In the embodiment of the present application, the SBFD time slot may be replaced by a SBFD symbol.

[0063] FIG3 is a schematic diagram of a method for sending information according to an embodiment of the present application. As shown in FIG3 , the method includes:

[0064] 301: The terminal device receives configuration information for configuring SBFD time domain resources; and

[0065] 302: The terminal device sends information through an uplink transmission that multiplexes uplink control information (UCI), wherein when UCI is multiplexed on an uplink transmission within a non-SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is determined according to a first parameter; when UCI is multiplexed on an uplink transmission within an SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is determined according to a second parameter.

[0066] In operation 301 , for example, a terminal device receives configuration information from a network device, where the configuration information is configuration information for configuring sub-band full-duplex (SBFD) time domain resources.

[0067] For example, the configuration information is used to enable the terminal device to know which symbols are SBFD symbols and which symbols are non-SBFD symbols.

[0068] In addition, the terminal device also receives configuration information for configuring SBFD frequency domain resources from the network device. Therefore, the above-mentioned "time domain resources" can also be replaced by "frequency domain resources" or "time-frequency resources".

[0069] In operation 302, the terminal device sends information through uplink transmission multiplexed with UCI.

[0070] In some embodiments, the uplink transmission is PUSCH or a part of PUSCH.

[0071] In some embodiments, the information sent through the uplink transmission includes at least one of uplink data and UCI sent through the PUSCH.

[0072] The following describes in detail how to multiplex UCI in uplink transmission.

[0073] When UCI is multiplexed for uplink transmission in non-SBFD symbols, the number of coded modulation symbols per layer used for UCI transmission is determined according to the first parameter; when UCI is multiplexed for uplink transmission in SBFD symbols, the number of coded modulation symbols per layer used for UCI transmission is determined according to the second parameter. The above "symbol" can also be replaced with "time slot". In other words, when UCI is multiplexed for uplink transmission in non-SBFD time slots, the number of coded modulation symbols per layer used for UCI transmission is determined according to the first parameter; when UCI is multiplexed for uplink transmission in SBFD time slots, the number of coded modulation symbols per layer used for UCI transmission is determined according to the second parameter.

[0074] In some embodiments, the first parameter and the second parameter are the same parameter with different values. For example, the first parameter is β1 and the second parameter is β2.

[0075] FIG4 is a schematic diagram of an SBFD time slot and a non-SBFD time slot according to an embodiment of the present application. For example, as shown in FIG4 , when UCI is multiplexed on PUSCH, if PUSCH is transmitted in a non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to β1; if PUSCH is transmitted in an SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to β2. i (i=1,2) is the parameter of network device configuration or indication. i Used to control the ratio between the PUSCH bit rate (or code rate) and the UCI bit rate (or code rate).

[0076] For simplicity, the embodiments of the present application (e.g., FIG. 4 ) are described using the example of a case where all symbols included in an SBFD time slot are SBFD symbols. In this case, "within an SBFD time slot" is equivalent to "within an SBFD symbol." This can be easily extended to the case where a portion of the symbols included in an SBFD time slot are SBFD symbols and another portion are non-SBFD symbols. In this case, "within an SBFD time slot" can be replaced with "within an SBFD symbol." The relationship between "non-SBFD time slot" and "non-SBFD symbol" can be derived similarly. The above description and extension apply to all embodiments of the present application.

[0077] For example, the number of coded modulation symbols per layer Q′ used for UCI transmission ACK,i According to β i Determine. For example, determine according to the following formula (2):

[0078] Among them, Q′ ACK,1 and Q′ ACK,2 These correspond to the two cases of non-SBFD time slot and SBFD time slot respectively;

[0079] The meanings of the parameters in the above formula (2) are as follows: For example, the strict definition of the parameters in formula (2) can be found in the relevant records of Section 6.3.2.4 of the existing standard TS 38.212-i00, which is not limited in the present embodiment:

[0080] K r is the number of bits in the rth code block of the UL-SCH;

[0081] C UL-SCH is the number of UL-SCH code blocks;

[0082] is the number of OFDM symbols of PUSCH (including DMRS);

[0083] is the number of REs available for UCI transmission in OFDM symbol 1 of PUSCH with UCI multiplexing; for OFDM symbols including DMRS, For OFDM symbols that do not include DMRS, Equal to the number of PUSCH subcarriers minus the number of PTRS subcarriers;

[0084] O ACK is the number of HARQ-ACK bits;

[0085] L ACK is the number of CRC bits of HARQ-ACK;

[0086] α is a scaling factor configured by higher layers and is used to control the upper limit of the number of coded modulation symbols per layer for UCI transmission;

[0087] l0 is the index of the first OFDM symbol after the first DMRS symbol of the PUSCH that does not include DMRS.

[0088] In some embodiments, the first parameter and / or the second parameter are configured by RRC signaling and / or are indicated by DCI. For example, β1 and / or β2 are configured by RRC signaling and / or are indicated by DCI.

[0089] In some embodiments, the first parameter and the second parameter are configured in one RRC IE, and / or the first parameter and the second parameter are indicated by one DCI, and / or the first parameter and the second parameter are respectively indicated by two DCIs.

[0090] For example, β1 and / or β2 can be configured through RRC signaling. For example, β1 and β2 are configured in PUSCH-Config and / or ConfiguredGrantConfig. For example, for a Type 1 configured grant, β1 and β2 for configured grant PUSCH are configured by RRC signaling, and a ConfiguredGrantConfig includes the configuration of β1 and β2. For example, a ConfiguredGrantConfig includes two sets of time and / or frequency resource configurations, which are respectively used to determine the configured grant resources in non-SBFD time slots and the configured grant resources in SBFD time slots, such as frequencyDomainAllocation and frequencyDomainAllocation1, frequencyDomainAllocation is used to configure frequency domain resources in non-SBFD time slots, and frequencyDomainAllocation1 is used to configure frequency domain resources in SBFD time slots.

[0091] For example, β1 and / or β2 may be indicated through DCI.

[0092] Figure 5 is a schematic diagram of indicating β1 and / or β2 through DCI according to an embodiment of the present application. For example, as shown in (a) and (b) in Figure 5, RRC signaling configures one or more β1s and one or more β2s, and a field in the DCI indicates one β1 and one β2. As shown in (a) in Figure 5, RRC signaling configures a group (4) of β1s and a group (4) of β2s, and a DCI field "01" indicates that the β1 is the second one in a group of β1s, and the indicated β2 is the second one in a group of β2s. As shown in (b) in Figure 5, RRC signaling configures multiple (4) (β1, β2) pairs, and a DCI field "01" indicates the second (β1, β2) pair. For example, the RRC configuration can be provided in PUSCH-Config and / or ConfiguredGrantConfig. The DCI may schedule dynamic grant PUSCH, or activate configured grant Type 2 PUSCH transmission, or schedule configured grant PUSCH retransmission (configured grant Type 2 PUSCH retransmission and / or configured grant Type 1 PUSCH retransmission).

[0093] FIG6 is another schematic diagram of an embodiment of the present application in which DCI is used to indicate β1 and / or β2. For example, as shown in FIG6 , RRC signaling configures a group (four) of β1 and a group (four) of β2, a DCI field "01" indicates β1, which is the second in the group of β1, and another DCI field "10" indicates β2, which is the second in the group of β2.

[0094] For example, β1 and β2 are indicated by two DCIs respectively, the first DCI indicates β1, and the second DCI indicates β2. For example, the first DCI schedules uplink transmission in a non-SBFD time slot, and the second DCI schedules uplink transmission in a SBFD time slot.

[0095] For example, β1 is configured by RRC and β2 is indicated by DCI, or β1 is indicated by DCI and β2 is configured by RRC.

[0096] In some embodiments, when a TB is transmitted through multiple time slots, when UCI is multiplexed on the uplink transmission within a non-SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is also determined according to a third parameter; when UCI is multiplexed on the uplink transmission within an SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is also determined according to a fourth parameter, wherein the third parameter and the fourth parameter are determined according to the ratio of the uplink transmission resources used for UCI multiplexing to the uplink transmission resources used for the TB transmission.

[0097] The above-mentioned "symbol" can also be replaced by "time slot". In other words, when a TB is transmitted through multiple time slots, when UCI is multiplexed on the uplink transmission in a non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is also determined according to the third parameter; when UCI is multiplexed on the uplink transmission in an SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is also determined according to the fourth parameter, wherein the third parameter and the fourth parameter are determined according to the ratio of the uplink transmission resources used for UCI multiplexing to the uplink transmission resources used for the TB transmission.

[0098] In some embodiments, the third parameter is γ1 and the fourth parameter is γ2.

[0099] For example, a TB is transmitted over multiple slots, and UCI is multiplexed on the PUSCH in one of the slots. If the PUSCH is transmitted in a non-SBFD slot, the number of coded modulation symbols per layer used for UCI transmission is determined by γ1; if the PUSCH is transmitted in an SBFD slot, the number of coded modulation symbols per layer used for UCI transmission is determined by γ2. i (i=1,2) is determined based on the ratio of PUSCH resources used for UCI multiplexing to all PUSCH resources used for TB transmission. For example, if numberOfSlotsTBoMS appears in the resource allocation table and numberOfSlotsTBoMS in the row indicated by the TDRA (Time domain resource assignment) field of the DCI is greater than 1, the DCI-scheduled TB is transmitted over multiple time slots.

[0100] FIG7 is another schematic diagram of an SBFD time slot and a non-SBFD time slot according to an embodiment of the present application. For example, as shown in FIG7 , a TB is transmitted through N1 non-SBFD time slots and N2 SBFD time slots. PUSCH transmission in a non-SBFD time slot uses F1 RBs, and PUSCH transmission in a SBFD time slot uses F2 RBs. The number of OFDM symbols used for PUSCH transmission in a non-SBFD time slot and in a SBFD time slot is equal. When UCI is multiplexed on the PUSCH in a non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to γ1. When UCI is multiplexed on the PUSCH in the SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to γ2. In FIG7 , RB is used as the frequency domain resource unit, and the frequency domain resource unit may also be a subband, RBG (Resource Block Group), PRG (Precoding Resource Block Group), etc.

[0101] For example, a TB is transmitted over multiple slots, and UCI is multiplexed on the PUSCH in one of the slots. The number of coded modulation symbols per layer used for UCI transmission is Q′. ACK,i According to γ i Determine, for example, according to formula (3).

[0102] in, is the number of REs available for UCI transmission in OFDM symbol l. OFDM symbols l and l0 are both OFDM symbols for PUSCH. PUSCH is PUSCH with UCI multiplexing, that is, PUSCH in the time slot with UCI transmission, not PUSCH in all time slots. For other parameters, refer to formula (2), and the similarities are not repeated here.

[0103] In some embodiments, when UCI is multiplexed on an actual repetition within a non-SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is determined based on the actual repetition within the non-SBFD symbol and the first parameter; when UCI is multiplexed on an actual repetition within a SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is determined based on the actual repetition within the SBFD symbol and the second parameter.

[0104] The above-mentioned "symbol" can also be replaced by "time slot". In other words, when UCI is multiplexed on the actual repetition (actual repetition) in a non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to the actual repetition in the non-SBFD time slot and the first parameter; when UCI is multiplexed on the actual repetition in a SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to the actual repetition in the SBFD time slot and the second parameter.

[0105] For example, when UCI is multiplexed on the actual repetition in a non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined based on the actual repetition and β1 in the non-SBFD time slot. When UCI is multiplexed on the actual repetition in an SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined based on the actual repetition and β2 in the SBFD time slot.

[0106] Figure 8 is another schematic diagram of the SBFD time slot and the non-SBFD time slot of an embodiment of the present application. For example, as shown in Figure 8, PUSCH repetition Type B spans the non-SBFD time slot and the SBFD time slot, and nominal repetition #1, #2, and #3 are split into actual repetition #1, #2, #3, and #4. When UCI is multiplexed into the actual repetition (#1 or #2) in the non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to the actual repetition and β1 in the non-SBFD time slot; when UCI is multiplexed into the actual repetition (#3 or #4) in the SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to the actual repetition and β2 in the SBFD time slot. For example, the number of coded modulation symbols per layer used for UCI transmission is determined according to the above formula (2), where, It refers to the number of REs available for UCI transmission in the OFDM symbol l with actual repetition of UCI multiplexing, for example Can be replaced by

[0107] In the above embodiments, the first parameter and the second parameter are the same parameter with different values, for example, β1 and β2; in some embodiments, the first parameter and the second parameter may also be the same parameter with the same value, for example, the first parameter and the second parameter are both β, in other words, β1=β2=β.

[0108] In some embodiments, β is configured by RRC signaling and / or indicated by DCI.

[0109] For example, regardless of whether the PUSCH with UCI multiplexing is transmitted in a non-SBFD time slot or a SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to the same β value, which is configured by RRC signaling and / or indicated by DCI.

[0110] In some embodiments, when a TB is transmitted through multiple time slots, when UCI is multiplexed on the uplink transmission within a non-SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is determined according to β and the fifth parameter; when UCI is multiplexed on the uplink transmission within the SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is determined according to β and the sixth parameter, wherein the fifth parameter and the sixth parameter are determined according to the ratio of the uplink transmission resources used for UCI multiplexing to the uplink transmission resources used for TB transmission.

[0111] The above-mentioned "symbol" can also be replaced by "time slot". In other words, when a TB is transmitted through multiple time slots, when UCI is multiplexed on the uplink transmission in the non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to β and the fifth parameter; when UCI is multiplexed on the uplink transmission in the SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to β and the sixth parameter, wherein the fifth parameter and the sixth parameter are determined according to the ratio of the uplink transmission resources used for UCI multiplexing to the uplink transmission resources used for TB transmission.

[0112] In some embodiments, the fifth parameter is γ1 and the sixth parameter is γ2.

[0113] For example, regardless of whether the PUSCH with UCI multiplexing is transmitted in a non-SBFD time slot or a SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to the same β value, so only one β value is used in the above formula (3), that is, β in formula (3) is replaced by i Replaced by β.

[0114] In some embodiments, when UCI is multiplexed for uplink transmission in a non-SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is determined based on β; when UCI is multiplexed for uplink transmission in a SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is determined based on β and a threshold.

[0115] The above "symbol" can also be replaced by "time slot". In other words, when UCI is multiplexed on uplink transmission in a non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to β; when UCI is multiplexed on uplink transmission in an SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to β and the threshold.

[0116] For example, regardless of whether the PUSCH with UCI is transmitted in a non-SBFD time slot or a SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined based on the PUSCH in the non-SBFD time slot and β, where the same β value is corresponding to both the non-SBFD time slot and the SBFD time slot. For example, when UCI is multiplexed on the PUSCH in a non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to the following formula (4); when UCI is multiplexed on the PUSCH in a SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is determined according to the following formula (5):

[0117] in, and The definition of is the same as that in the above formula (2) The subscripts NSB and SB are added here to facilitate the description of the non-SBFD time slot and the SBFD time slot. That is, the definition in the above formula (2) is applied to the non-SBFD time slot and the SBFD time slot respectively. The meanings of other symbols are similar.

[0118] For UCI multiplexing in non-SBFD time slots, the number of coded modulation symbols per layer used for UCI transmission can be obtained according to formula (4). For UCI multiplexing in SBFD time slots, the number of coded modulation symbols per layer used for UCI transmission can still be obtained according to the method of non-SBFD time slots, and on this basis, it is additionally restricted to not exceed the threshold related to the SBFD time slot For example, the PUSCH in a non-SBFD time slot and the PUSCH in a SBFD time slot are two repetitions of a PUSCH repetition, or two configured grant PUSCHs belonging to the same configured grant, or two transmissions of a TB transmitted through multiple time slots, or two PUSCHs scheduled by the same DCI.

[0119] In some embodiments, whether the first parameter and the second parameter used by the terminal device for non-SBFD symbols and SBFD symbols are both β or are β1 and β2 respectively is configured by RRC signaling.

[0120] The above-mentioned "symbol" can also be replaced by "time slot". In other words, whether the first parameter and the second parameter used by the terminal device for non-SBFD time slots and SBFD time slots are both β or β1 and β2 respectively is configured by RRC signaling.

[0121] For example, RRC signaling can configure the terminal device to use the same β for non-SBFD time slots and SBFD time slots or to use β1 and β2 respectively.

[0122] In some embodiments, when UCI is multiplexed on uplink transmission within a non-SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is also determined based on the seventh parameter; when UCI is multiplexed on uplink transmission within a SBFD symbol, the number of coded modulation symbols per layer used for UCI transmission is also determined based on the eighth parameter.

[0123] The above-mentioned "symbol" can also be replaced by "time slot". In other words, when UCI is multiplexed on the uplink transmission in the non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is also determined according to the seventh parameter; when UCI is multiplexed on the uplink transmission in the SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is also determined according to the eighth parameter.

[0124] In some embodiments, the seventh parameter is α1 and the eighth parameter is α2.

[0125] For example, when UCI is multiplexed on the PUSCH in a non-SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is further determined based on α1. When UCI is multiplexed on the PUSCH in an SBFD time slot, the number of coded modulation symbols per layer used for UCI transmission is further determined based on α2. For example, α in the aforementioned formulas (2)-(5) is replaced with α1 or α2, respectively.

[0126] The above embodiment is described only using HARQ-ACK as UCI as an example, and can be extended to other types of UCI, including CSI part 1, CSI part 2, CG-UCI, etc., for example, according to section 6.3.2.4 of the existing standard TS 38.212-i00. The aforementioned "UCI multiplexing on PUSCH" can also be extended to the case of "UCI transmitted on PUSCH without UL-SCH", for example, according to section 6.3.2.4 of the existing standard TS 38.212-i00.

[0127] As can be seen from the above embodiment, the terminal device determines the number of coded modulation symbols per layer used for UCI transmission based on independent parameters, depending on whether the uplink transmission is in a non-SBFD symbol (or time slot) or an SBFD symbol (or time slot). This helps improve the reliability of uplink transmission when UCI is multiplexed in an SBFD symbol (or time slot).

[0141] The third parameter and the fourth parameter are determined according to the ratio of the uplink transmission resources used for UCI multiplexing to the uplink transmission resources used for the TB transmission.

[0142] In some embodiments, the first parameter and the second parameter are both β,

[0143] In the case where a TB received by the network device is transmitted via multiple time slots,

[0146] The fifth parameter and the sixth parameter are determined according to the ratio of uplink transmission resources used for UCI multiplexing to uplink transmission resources used for TB transmission.

[0147] In some embodiments, when UCI is multiplexed on uplink transmission within non-SBFD symbols, the number of coded modulation symbols per layer used for UCI transmission is further determined according to the seventh parameter;

[0148] When UCI is multiplexed on uplink transmission within SBFD symbols, the number of coded modulation symbols per layer used for UCI transmission is also determined according to the eighth parameter,

[0150] In the embodiment of the present application, the specific implementation of the above operations 901-902 can refer to the relevant records in the embodiment of the first aspect, and will not be repeated here.

[0151] As can be seen from the above embodiment, the terminal device determines the number of coded modulation symbols per layer used for UCI transmission based on independent parameters, depending on whether the uplink transmission is in a non-SBFD symbol (or time slot) or an SBFD symbol (or time slot). This helps improve the reliability of uplink transmission when UCI is multiplexed in an SBFD symbol (or time slot).
