Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a message sending method, receiving method, apparatus, terminal and network device. Background Technology

[0002] 5G NR supports Time Division Duplex (TDD) and Frequency Division Duplex (FDD). Currently, existing technologies support full-duplex with non-overlapping subbands, meaning a base station can simultaneously transmit and receive within a single frequency band / carrier / BWP using different subbands, without overlap between the subbands used for transmission and reception. For example... Figure 1 As shown, the uplink subband exists in some symbols and does not overlap with other frequency domain resources.

[0003] On the network side, uplink subbands (UL subbands) can be configured on symbols set to DL or flexible in TDD-UL-DL-ConfigCommon. In this document, symbols configured with UL subbands are referred to as SubBand FullDuplex (SBFD) symbols. Only SBFD-aware UEs can perform uplink transmissions on the UL subband. Here, SBFD-aware UE refers to a terminal that supports SBFD. Symbols without configured UL subbands (including symbols set to UL in TDD-UL-DL-ConfigCommon) are referred to as non-SBFD symbols, and all terminals transmit according to the configured symbol direction.

[0004] In related technologies, the calculation method for the transmission power of the Msg3 (PUSCH) channel for random access transmission in a random access opportunity (RACH Occasion, RO) is as follows:

[0005]

[0006] Among them, P CMAX,f，c (i) is the maximum transmit power of the UE as defined in RAN4, P O_PUSCH,b，f，c (j) is P O_NOMINAL,PUSCH,f，c (j) and P O_UE_PUSCH,b，f，c The sum of (j), for Msg3 PUSCH in the random access process, P O_UE_PUSCH,b，f，c (0) = 0, P O_NOMINAL,PUSCH,f，c (0)=P O_PRE +Δ PREAMBLE,Msg3 Among them, is P. O_PRE The network-side preamble target received power, ΔPREAMBLE_Msg3 The value of Δ is determined by the msg3-DeltaPreamble or deltaPreamble parameter configured on the network side. Both parameters represent the gap between the Msg3 PUSCH transmit power and the preamble transmit power. msg3-DeltaPreamble is configured in PUSCH-ConfigCommon, while deltaPreamble is bound to the feature combination introduced in Rel-17 in RACH-ConfigCommon. When both parameters are configured in the RRC, Δ... PREAMBLE_Msg3 Based on deltaPreamble, when neither parameter is configured, Δ PREAMBLE_Msg3 The value is 0. μ is the exponent corresponding to the subcarrier spacing. It is the bandwidth allocated to PUSCH resources, α b，f，c (j) Configured by the msg3-Alpha parameter on the network side, PL b，f，c (q d Δ is the downlink path loss calculated by the UE using the reference signal. TF，b，f，c (i) is the power scaling parameter calculated based on the number of PUSCH transport layers, f b，f，c (i, l) are power adjustment parameters indicated by TPC signaling.

[0007] In related technologies, a single Random Access Channel (RACH) configuration has only one msg3-DeltaPreamble or deltaPreamble. However, after the introduction of SBFD, the symbol type of Msg3PUSCH transmission and the RO type of preamble transmission can vary. It is difficult to accurately calculate the Msg3PUSCH transmission power under different conditions using only one msg3-DeltaPreamble or deltaPreamble. Summary of the Invention

[0169] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network device 12. The terminal involved in this application embodiment, also referred to as a terminal device, can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem, etc. The name of the terminal device may differ in different systems; for example, in a 5G system, the terminal device can be called User Equipment (UE). The wireless terminal device can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges voice and / or data with the radio access network.

Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile device, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device; however, this application does not limit the terminology used in its embodiments.

[0170] The network device involved in this application embodiment can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names.

[0172] This application provides a message sending method, receiving method, apparatus, terminal, and network device, which configure corresponding power offsets for different symbol types and / or RO types to achieve more accurate power control.

[0173] like Figure 2 As shown, this application embodiment provides a message sending method, executed by a terminal, including:

[0174] Step 21: Determine the target power offset based on the target symbol type and / or the target RO type; wherein, the target symbol type is the symbol type of the Physical Uplink Shared Channel (PUSCH) transmission carrying the random access message 3 sent by the terminal, and the target RO type is the RO type of the random access preamble transmission sent by the terminal.

[0175] Step 22: Send the random access message 3, wherein the transmission power of the message 3 is related to the target power offset.

[0176] Through the above steps, in this embodiment of the application, the terminal can determine the corresponding power offset according to different symbol types and / or RO types, and then determine the transmission power of message 3, thereby achieving more accurate power control.

[0177] In this embodiment, the terminal can pre-obtain a power offset parameter set, which includes at least one power offset. In step 21 above, the terminal can select the target power offset from the power offset parameter set based on the target symbol type and / or target RO type, wherein the target power offset includes at least one of the following:

[0178] (1) A power offset in the power offset parameter set;

[0179] (2) The two power offsets in the power offset parameter set;

[0180] (3) The sum of the two power offsets in the power offset parameter set.

[0181] In this way, the terminal can determine the transmission power of message 3 based on the target power offset. For example, the parameter Δ in the formula above can be determined based on the target power offset. PREAMBLE_Msg3 Then, using the formula mentioned earlier or a similar formula, the transmission power of message 3 is determined. Parameter Δ PREAMBLE_Msg3 This can be described as the power offset of the transmission Msg3 relative to the transmission preamble.

[0182] Specifically, the power offset parameter set includes at least one of the following power offsets:

[0183] (1) First power offset, the first power offset is the power offset of the terminal transmitting Msg3PUSCH on the first symbol type relative to transmitting preamble on the first RO type;

[0184] (2) Second power offset, the second power offset is the power offset of the terminal transmitting Msg3PUSCH on the second symbol type relative to transmitting preamble on the first RO type;

[0185] (3) The third power offset is used together with the first power offset to determine the second power offset, or it is used together with the second power offset to determine the first power offset;

[0186] (4) Fourth power offset, the fourth power offset being the power offset of the terminal transmitting Msg3PUSCH on the second symbol type relative to transmitting preamble on the second RO type;

[0187] (5) Fifth power offset, the fifth power offset being the power offset of the terminal transmitting Msg3PUSCH on the first symbol type relative to transmitting preamble on the second RO type;

[0188] (6) The sixth power offset is used to determine the fifth power offset together with the fourth power offset, or to determine the fourth power offset together with the fifth power offset;

[0189] (7) Seventh power offset, the seventh power offset being the power offset of the terminal transmitting Msg3 PUSCH relative to the transmission of preamble on the first RO type;

[0190] (8) Eighth power offset, the eighth power offset being the power offset of the terminal transmission Msg3 PUSCH relative to the transmission of preamble on the second RO type;

[0191] (9) Ninth power offset, used together with the first power offset to determine the second power offset, or together with the second power offset to determine the first power offset; and together with the fourth power offset to determine the fifth power offset, or together with the fifth power offset to determine the fourth power offset.

[0192] In this embodiment, the values ​​of the third power offset and the sixth power offset can be the same or different. Furthermore, the third power offset and the sixth power offset can also be predefined by the protocol, and their predefined values ​​can be the same or different.

[0193] The following are some examples of the power offset parameter set. It should be noted that the following examples are only a partial example of the power offset parameter set and do not list all sets.

[0194] Power offset parameter set 1 includes: first power offset, second power offset, fourth power offset and fifth power offset;

[0195] Power offset parameter set 2 includes: first power offset, third power offset, fourth power offset and sixth power offset;

[0196] The power offset parameter set 3 includes: second power offset, third power offset, fourth power offset and sixth power offset;

[0197] The power offset parameter set 4 includes: first power offset, third power offset, fifth power offset and sixth power offset;

[0198] The power offset parameter set 5 includes: second power offset, third power offset, fifth power offset and sixth power offset;

[0199] The power offset parameter set 6 includes: the first power offset, the fourth power offset, and the ninth power offset;

[0200] The power offset parameter set 7 includes: the second power offset, the fourth power offset, and the ninth power offset;

[0201] The power offset parameter set 8 includes: the first power offset, the fifth power offset, and the ninth power offset;

[0202] The power offset parameter set 9 includes: the second power offset, the fifth power offset, and the ninth power offset;

[0203] The power offset parameter set 10 includes: the seventh power offset and the eighth power offset.

[0204] In this embodiment of the application, the terminal can obtain the power offset parameter set in different ways.

[0205] For example, as one implementation, the terminal receives first configuration information sent by the network device, the first configuration information being used to configure the power offset parameter set; the terminal can directly determine the power offset parameter set based on the first configuration information. The first configuration information can be sent via RRC signaling.

[0206] For example, as another implementation, the terminal can receive second configuration information sent by the network device. This second configuration information is used to configure at least one of the following power offsets: a first power offset, a second power offset, a fourth power offset, a fifth power offset, a seventh power offset, and an eighth power offset. The terminal also obtains at least one predefined power offset: a third power offset, a sixth power offset, and a ninth power offset. Thus, the terminal can determine the power offset parameter set based on the second configuration information and the predefined power offsets. The predefined power offsets can be predefined in relevant standard protocols. This allows the predefined power offsets to be configured locally on the terminal. The second configuration information can be sent via RRC signaling.

[0207] In this embodiment, there can be multiple RO types and two symbol types. The following explanation primarily uses the example where both RO types and symbol types are two. That is, the RO types include a first RO type and a second RO type, and the symbol types include a first symbol type and a second symbol type. In this case, the RO types and / or symbol types can form various different combinations (cases). Table 1 provides examples of several cases.

[0208] Table 1

[0209] Case RO type Symbol type Case 1 First RO type First symbol type Case 2 First RO type Second symbol type Case 3 Second RO type Second symbol type Case 4 Second RO type First symbol type Case 5 First RO type - Case 6 Second RO type -

[0210] After determining the power offset parameter set, the terminal can select the target power offset from the power offset parameter set according to the target symbol type and / or target RO type. Specifically, the selection includes any of the following:

[0211] (1) In the case where the target RO type is the first RO type and the target symbol type is the first symbol type (i.e., Case 1), the target power offset includes at least one of the following: the first power offset; the second power offset and the third power offset; the sum of the second power offset and the third power offset; the second power offset and the ninth power offset; the sum of the second power offset and the ninth power offset.

[0212] For example, in the case where the target RO type is the first RO type and the target symbol type is the first symbol type (i.e., Case 1):

[0213] If the power offset parameter set is the aforementioned power offset parameter set 1, set 2, set 4, set 6 or set 8, then the target power offset is the first power offset;

[0214] If the power offset parameter set is the aforementioned power offset parameter set 3 or set 5, then the target power offset is the second power offset and the third power offset, or the target power offset is the sum of the second power offset and the third power offset;

[0215] If the power offset parameter set is the aforementioned power offset parameter set 7 or set 9, then the target power offset is the second power offset and the ninth power offset, or the target power offset is the sum of the second power offset and the ninth power offset.

[0216] (2) In the case where the target RO type is the first RO type and the target symbol type is the second symbol type (i.e., Case 2), the target power offset includes at least one of the following: the second power offset; the first power offset and the third power offset; the sum of the first power offset and the third power offset; the first power offset and the ninth power offset; the sum of the first power offset and the ninth power offset.

[0217] For example, in the case where the target RO type is the first RO type and the target symbol type is the second symbol type (i.e., Case 2):

[0218] If the power offset parameter set is the aforementioned power offset parameter set 1, set 3, set 5, set 7 or set 9, then the target power offset is the second power offset;

[0219] If the power offset parameter set is the power offset parameter set 2 or set 4 mentioned above, then the target power offset is the first power offset and the third power offset, or the target power offset is the sum of the first power offset and the third power offset;

[0220] If the power offset parameter set is the aforementioned power offset parameter set 6 or set 8, then the target power offset is the first power offset and the ninth power offset, or the target power offset is the sum of the first power offset and the ninth power offset.

[0221] (3) In the case where the target RO type is the second RO type and the target symbol type is the second symbol type (i.e., Case 3), the target power offset includes at least one of the following: the fourth power offset; the fifth power offset and the sixth power offset; the sum of the fifth power offset and the sixth power offset; the fifth power offset and the ninth power offset; the sum of the fifth power offset and the ninth power offset; and the eighth power offset.

[0222] For example, in the case where the target RO type is the second RO type and the target symbol type is the second symbol type (i.e., Case 3):

[0223] If the power offset parameter set is the aforementioned power offset parameter set 1, set 2, set 3, set 6 or set 7, then the target power offset is the fourth power offset;

[0224] If the power offset parameter set is the aforementioned power offset parameter set 4 or set 5, then the target power offset is the fifth power offset and the sixth power offset, or the target power offset is the sum of the fifth power offset and the sixth power offset;

[0225] If the power offset parameter set is the aforementioned power offset parameter set 8 or set 9, then the target power offset is the fifth power offset and the ninth power offset, or the target power offset is the sum of the fifth power offset and the ninth power offset.

[0226] (4) In the case where the target RO type is the second RO type and the target symbol type is the first symbol type (i.e., Case 4), the target power offset includes at least one of the following: the fifth power offset; the fourth power offset and the sixth power offset; the sum of the fourth power offset and the sixth power offset; the fourth power offset and the ninth power offset; the sum of the fourth power offset and the ninth power offset.

[0227] For example, in the case where the target RO type is the second RO type and the target symbol type is the first symbol type (i.e., Case 4):

[0228] If the power offset parameter set is the aforementioned power offset parameter set 1, set 4, set 5, set 8, or set 9, then the target power offset is the fifth power offset;

[0229] If the power offset parameter set is the power offset parameter set 2 or set 3 mentioned above, then the target power offset is the fourth power offset and the sixth power offset, or the target power offset is the sum of the fourth power offset and the sixth power offset;

[0230] If the power offset parameter set is the aforementioned power offset parameter set 6 or set 7, then the target power offset is the fourth power offset and the ninth power offset, or the target power offset is the sum of the fourth power offset and the ninth power offset.

[0231] (5) In the case where the target RO type is the first RO type (i.e., Case 5), the target power offset is the seventh power offset.

[0232] For example, in the case where the target RO type is the first RO type (i.e., Case 5):

[0233] If the power offset parameter set is the aforementioned power offset parameter set 10, then the target power offset is the seventh power offset.

[0234] (6) In the case that the target RO type is the second RO type (i.e., Case 6), the target power offset is the eighth power offset.

[0235] For example, in the case where the target RO type is the second RO type (i.e., Case 6):

[0236] If the power offset parameter set is the aforementioned power offset parameter set 10, then the target power offset is the eighth power offset.

[0237] In this embodiment of the application, the terminal may be a first type of terminal that supports sub-band full-duplex SBFD (sometimes referred to herein as an SBFD aware UE), or a second type of terminal that does not support SFBF (sometimes referred to herein as a Non-SBFD UE).

[0238] The first symbol type is a symbol type that supports SBFD (sometimes referred to as SBFD symbol in this document), and the second symbol type is a symbol type that does not support SBFD (sometimes referred to as non-SBFD symbol in this document).

[0239] The first RO type is an additional RO, and the second RO type is a legacy RO. An additional RO can be a set of legacy RACH configurations for SBFD-aware UEs configured on SBFD DL symbols, or a set of additional RACH configurations for SBFD-aware UEs configured on SBFD symbols. A legacy RO is any RO available to non-SBFD UEs, such as legacy RACH configurations on SBFD Flexible symbols and non-SBFD symbols.

[0240] Please refer to Figure 3 The message receiving method provided in this application embodiment is executed by a network device and includes the following steps:

[0241] Step 31: Receive message 3 of random access sent by the terminal;

[0242] The transmission power of message 3 is related to the target power offset; the target power offset is determined based on the target symbol type and / or the target RO type, where the target symbol type is the symbol type of the PUSCH transmission carrying the random access message 3 sent by the terminal, and the target RO type is the RO type of the preamble transmission of the random access sent by the terminal.

[0243] In the above steps, the power of the terminal sending message 3 is related to the target symbol type and / or target RO type, thereby configuring the corresponding power offset according to different symbol types and / or RO types, which can achieve more accurate power control.

[0244] In this embodiment, the target power offset is selected by the terminal from a power offset parameter set based on the target symbol type and / or target RO type. The power offset parameter set includes at least one power offset. Specifically, the target power offset includes at least one of the following:

[0245] (1) A power offset in the power offset parameter set;

[0246] (2) The two power offsets in the power offset parameter set;

[0247] (3) The sum of the two power offsets in the power offset parameter set.

[0248] As one implementation, prior to step 31 above, the network device can send first configuration information to the terminal, which is used to configure a power offset parameter set. In this way, the terminal can directly obtain the power offset parameter set based on the first configuration information.

[0249] Specifically, the power offset parameter set may include at least one of the following power offsets:

[0250] (1) First power offset, the first power offset is the power offset of the terminal transmitting Msg3PUSCH on the first symbol type relative to transmitting preamble on the first RO type;

[0251] (2) Second power offset, the second power offset is the power offset of the terminal transmitting Msg3PUSCH on the second symbol type relative to transmitting preamble on the first RO type;

[0252] (3) The third power offset is used together with the first power offset to determine the second power offset, or it is used together with the second power offset to determine the first power offset;

[0253] (4) Fourth power offset, the fourth power offset being the power offset of the terminal transmitting Msg3PUSCH on the second symbol type relative to transmitting preamble on the second RO type;

[0254] (5) Fifth power offset, the fifth power offset being the power offset of the terminal transmitting Msg3PUSCH on the first symbol type relative to transmitting preamble on the second RO type;

[0255] (6) The sixth power offset is used to determine the fifth power offset together with the fourth power offset, or to determine the fourth power offset together with the fifth power offset;

[0256] (7) Seventh power offset, the seventh power offset being the power offset of the terminal transmitting Msg3 PUSCH relative to the transmission of preamble on the first RO type;

[0257] (8) Eighth power offset, the eighth power offset being the power offset of the terminal transmission Msg3 PUSCH relative to the transmission of preamble on the second RO type;

[0258] (9) Ninth power offset, used together with the first power offset to determine the second power offset, or together with the second power offset to determine the first power offset; and together with the fourth power offset to determine the fifth power offset, or together with the fifth power offset to determine the fourth power offset.

[0259] As another implementation, the network device can send second configuration information to the terminal. This second configuration information is used to configure a first power offset, which, together with a predefined second power offset, is used to determine a set of power offset parameters. The second power offset can be predefined in a standard protocol and is typically pre-configured locally on the terminal.

[0260] Specifically, the first portion of power offset may include at least one of the following:

[0261] (1) First power offset, the first power offset is the power offset of the terminal transmitting Msg3PUSCH on the first symbol type relative to transmitting preamble on the first RO type;

[0262] (2) Second power offset, the second power offset is the power offset of the terminal transmitting Msg3PUSCH on the second symbol type relative to transmitting preamble on the first RO type;

[0263] (3) Fourth power offset, the fourth power offset being the power offset of the terminal transmitting Msg3PUSCH on the second symbol type relative to transmitting preamble on the second RO type;

[0264] (4) Fifth power offset, the fifth power offset being the power offset of the terminal transmitting Msg3PUSCH on the first symbol type relative to transmitting preamble on the second RO type;

[0265] (5) Seventh power offset, the seventh power offset being the power offset of the terminal transmitting Msg3 PUSCH relative to the transmission of preamble on the first RO type;

[0266] (6) Eighth power offset, the eighth power offset being the power offset of the terminal transmission Msg3 PUSCH relative to the transmission of preamble on the second RO type;

[0267] The second portion of the power offset may include at least one of the following:

[0268] (1) The third power offset is used together with the first power offset to determine the second power offset, or it is used together with the second power offset to determine the first power offset;

[0269] (2) The sixth power offset is used to determine the fifth power offset together with the fourth power offset, or to determine the fourth power offset together with the fifth power offset;

[0270] (3) Ninth power offset, used together with the first power offset to determine the second power offset, or together with the second power offset to determine the first power offset; and together with the fourth power offset to determine the fifth power offset, or together with the fifth power offset to determine the fourth power offset.

[0271] The following describes the method of the embodiments of this application further through several examples, taking the first symbol type as a symbol type that supports SBFD (sometimes referred to as SBFD symbol in this document), the second symbol type as a symbol type that does not support SBFD (sometimes referred to as non-SBFD symbol in this document), the first RO type as an additional RO, and the second RO type as a legacy RO.

[0272] In the following examples:

[0273] The RO types for preamble transmissions include a first RO type and a second RO type. The first RO type is an additional RO, and the second RO type is a legacy RO. The symbol types for Msg3 PUSCH transmissions include a first symbol type and a second symbol type. The first symbol type is an SBFD symbol, and the second symbol type is a non-SBFD symbol.

[0274] SBFD-aware UEs can transmit preambles on additional ROs or on legacy ROs. An additional RO can be a set of legacy RACH configurations for SBFD-aware UEs configured on SBFD DL symbols, or a set of additional RACH configurations for SBFD-aware UEs configured on SBFD symbols. Legacy ROs are all ROs available to non-SBFD UEs, such as ROs with legacy RACH configurations on SBFD Flexible symbols and non-SBFD symbols.

[0275] When the base station receives a preamble sent by the UE on the additional RO, since an SBFD aware UE can send a preamble on the additional RO while a non-SBFD UE cannot, the base station can identify the UE as an SBFD aware UE. The base station can schedule Msg3 PUSCH for the SBFD aware UE on either the SBFD symbol or the non-SBFD symbol.

[0276] Another scenario is that the base station receives a preamble sent by the UE on the legacy RO. In this case, the base station cannot identify whether the UE is an SBFD-aware UE, because both non-SBFD UEs and SBFD-aware UEs can send preambles on the legacy RO. In this situation, the base station considers the UE to be a non-SBFD UE, and the base station can schedule Msg3 PUSCH for the SBFD-aware UE on the non-SBFD symbol or the SBFD Flexible symbol.

[0277] In all the examples below, the x-th power offset corresponds to an RRC configuration parameter msg3-DeltaPreamble or deltaPreamble. Different power offsets may actually correspond to different RRC parameters with suffixes, such as msg3-DeltaPreamble-SBFD or deltaPreamble-SBFD. This application does not limit such suffixes. The target power offset is used to determine Δ. PREAMBLE,Msg3 The corresponding value.

[0278] The RO type and the symbol type of the Msg3 transmission in the SBFD-aware UE preamble transmission can be combined in the following four ways:

[0279] Case 1: The UE transmits a preamble on the additional RO and Msg3PUSCH on the SBFD symbol;

[0280] Case 2: The UE transmits a preamble on additional RO and Msg3PUSCH on non-SBFD symbols;

[0281] Case 3: The UE transmits a preamble on legacy RO and Msg3PUSCH on non-SBFD symbols;

[0282] Case 4: The UE transmits a preamble on legacy RO and Msg3PUSCH on SBFD symbols.

[0283] Examples 1-4 below are examples of SBFD-aware UEs, and example 5 is an example of a non-SBFD UE.

[0284] Example 1:

[0285] In this example, the network side configures a first power offset and a second power offset for Case 1 and Case 2, respectively. That is, in Case 1, the power offset of Msg3 PUSCH relative to the preamble is the value of the first power offset, and in Case 2, the power offset of Msg3 PUSCH relative to the preamble is the value of the second power offset. Similarly, the network side configures a fourth power offset and a fifth power offset for Case 3 and Case 4, respectively. That is, in Case 3, the power offset of Msg3 PUSCH relative to the preamble is the value of the fourth power offset, and in Case 4, the power offset of Msg3 PUSCH relative to the preamble is the value of the fifth power offset.

[0286] If the power offset parameter is configured in the PUSCH-ConfigCommon IE, then the first, second, fourth, and fifth power offsets are configured simultaneously in that IE. If the power offset parameter is configured in the RACH-ConfigCommon IE, and that RACH configuration is a legacy RACH configuration that configures both additional RO and legacy RO, then the first, second, fourth, and fifth power offsets are configured simultaneously in the IE. If the power offset parameter is configured in the RACH-ConfigCommon IE, and that RACH configuration is an additional RACH configuration that only configures additional RO, then only the first and second power offsets are configured in the IE. If the power offset parameter is configured in the RACH-ConfigCommon IE, and that RACH configuration is a legacy RACH configuration that only configures legacy RO, then only the fourth and fifth power offsets are configured in the IE. After the random access procedure begins, the UE needs to initialize the parameters of the above RRC configuration.

[0287] The SBFD-aware UE selects the target power offset based on the symbol type of the Msg3 PUSCH transmission and the RO type of the preamble transmission. Specifically,

[0288] When an SBFD-aware UE transmits a preamble on an additional RO and a Msg3 PUSCH on a non-SBFD symbol, the target power offset is the first power offset, and the UE uses the first power offset when calculating the Msg3 PUSCH transmission power. When an SBFD-aware UE transmits a preamble on an additional RO and a Msg3 PUSCH on an SBFD symbol, the target power offset is the second power offset, and the UE uses the second power offset when calculating the Msg3 PUSCH transmission power.

[0289] Alternatively, in this example, only the first power offset is configured, and the second power offset is not required. That is, in Case 1 and Case 2, the power offset of Msg3 PUSCH relative to the preamble is the value of the first power offset. When the SBFD-aware UE transmits the preamble on the additional RO, regardless of whether the UE transmits Msg3PUSCH on a non-SBFD symbol or an SBFD symbol, the target power offset is the first power offset, and the UE uses the first power offset when calculating the transmission power of Msg3 PUSCH.

[0290] When an SBFD-aware UE transmits a preamble on a legacy RO and Msg3PUSCH on a non-SBFD symbol, the target power offset is the fourth power offset, which the UE uses when calculating the Msg3PUSCH transmission power. When an SBFD-aware UE transmits a preamble on an additional RO and Msg3PUSCH on an SBFD symbol, the target power offset is the fifth power offset, which the UE uses when calculating the Msg3PUSCH transmission power.

[0291] Alternatively, in this example, only the fourth power offset is configured, and the fifth power offset is not required. That is, in Case 3 and Case 4, the power offset of Msg3 PUSCH relative to the preamble is the value of the fourth power offset. When the SBFD-aware UE transmits the preamble on the legacy RO, regardless of whether the UE transmits Msg3 PUSCH on a non-SBFD symbol or an SBFD symbol, the target power offset is the fourth power offset, and the UE uses the fourth power offset when calculating the transmission power of Msg3 PUSCH.

[0292] Alternatively, in this example, only the fourth power offset is configured, and the fifth power offset is not required. That is, only Case 3 exists, and Case 4 does not exist. In Case 3, the power offset of Msg3 PUSCH relative to the preamble is always the value of the fourth power offset. When an SBFD-aware UE transmits the preamble on a legacy RO and transmits Msg3 PUSCH on a non-SBFD symbol, the target power offset is always the fourth power offset, and the UE uses the fourth power offset when calculating the transmission power of Msg3 PUSCH.

[0293] Example 2:

[0294] In this example, the network side configures a first power offset and a third power offset for Case 1 and Case 2. Specifically, in Case 1, the power offset of Msg3 PUSCH relative to the preamble is the value of the first power offset, and in Case 2, the power offset of Msg3 PUSCH relative to the preamble is the sum of the values ​​of the first and third power offsets. The network side configures a fourth power offset and a sixth power offset for Case 3 and Case 4. Specifically, in Case 3, the power offset of Msg3 PUSCH relative to the preamble is the value of the fourth power offset, and in Case 4, the power offset of Msg3 PUSCH relative to the preamble is the sum of the values ​​of the fourth and sixth power offsets.

[0295] The SBFD-aware UE selects the target power offset based on the symbol type of the Msg3 PUSCH transmission and the RO type of the preamble transmission. Specifically,

[0296] When an SBFD-aware UE transmits a preamble on an additional RO and a Msg3 PUSCH on a non-SBFD symbol, the target power offset is the first power offset, which the UE uses when calculating the Msg3 PUSCH transmission power. When an SBFD-aware UE transmits a preamble on an additional RO and a Msg3 PUSCH on an SBFD symbol, the target power offset is the first power offset and the third power offset, which the UE uses when calculating the Msg3 PUSCH transmission power, for example, the sum of the two.

[0297] When an SBFD-aware UE transmits a preamble on a legacy RO and Msg3PUSCH on a non-SBFD symbol, the target power offset is the fourth power offset, which the UE uses when calculating the Msg3 PUSCH transmission power. When an SBFD-aware UE transmits a preamble on an additional RO and Msg3 PUSCH on an SBFD symbol, the target power offset is the fourth and sixth power offsets, which the UE uses when calculating the Msg3 PUSCH transmission power, for example, the sum of the four power offsets.

[0298] In this example, the values ​​of the third and sixth power offsets configured on the network side can be the same or different. Furthermore, the third and sixth power offsets can also be predefined by the protocol, and their predefined values ​​can be the same or different.

[0299] Example 3:

[0300] In this example, the network side configures a second power offset and a third power offset for Case 1 and Case 2. The third power offset is the offset of the UE transmitting Msg3 PUSCH on non-SBFD symbols relative to transmitting Msg3 PUSCH on SBFD symbols when the preamble is transmitted on the additional RO. That is, in Case 1, the power offset of Msg3 PUSCH relative to the preamble is the sum of the values ​​of the second power offset and the third power offset, and in Case 2, the power offset of Msg3 PUSCH relative to the preamble is the value of the second power offset. The network side configures a fourth power offset and a sixth power offset for Case 3 and Case 4. The sixth power offset is the offset of the UE transmitting Msg3 non-PUSCH on SBFD symbols relative to transmitting Msg3 PUSCH on SBFD symbols when the preamble is transmitted on the legacy RO. That is, in Case 3, the power offset of Msg3PUSCH relative to the preamble is the value of the fourth power offset, and in Case 4, the power offset of Msg3PUSCH relative to the preamble is the sum of the values ​​of the fourth power offset and the sixth power offset.

[0301] If the power offset parameter is configured in the PUSCH-ConfigCommon IE, then the first, third, fourth, and sixth power offsets are configured simultaneously in that IE. If the power offset parameter is configured in the RACH-ConfigCommon IE, and that RACH configuration is a legacy RACH configuration that configures both additional ROs and legacy ROs, then the second, third, fourth, and sixth power offsets are configured simultaneously in the IE. If the power offset parameter is configured in the RACH-ConfigCommon IE, and that RACH configuration is an additional RACH configuration that only configures additional ROs, then the second and third power offsets are configured in the IE. If the power offset parameter is configured in the RACH-ConfigCommon IE, and that RACH configuration is a legacy RACH configuration that only configures legacy ROs, then the fourth and sixth power offsets are configured in the IE. After the random access procedure begins, the UE needs to initialize the parameters of the above RRC configuration.

[0302] The SBFD-aware UE selects the target power offset based on the symbol type of the Msg3 PUSCH transmission and the RO type of the preamble transmission. Specifically,

[0303] When an SBFD-aware UE transmits a preamble on an additional RO and a Msg3 PUSCH on a non-SBFD symbol, the target power offset is a second power offset and a third power offset. The UE uses the second and third power offsets, for example, their sum, when calculating the Msg3 PUSCH transmission power.

[0304] When an SBFD-aware UE transmits a preamble on a legacy RO and Msg3PUSCH on a non-SBFD symbol, the target power offset is the fourth power offset, which the UE uses when calculating the Msg3 PUSCH transmission power. When an SBFD-aware UE transmits a preamble on an additional RO and Msg3 PUSCH on an SBFD symbol, the target power offset is the sum of the fourth and sixth power offsets, which the UE uses when calculating the Msg3 PUSCH transmission power.

[0305] In this example, the values ​​of the third and sixth power offsets configured on the network side can be the same or different. Furthermore, the third and sixth power offsets can also be predefined by the protocol, and their predefined values ​​can be the same or different.

[0306] Example 4:

[0307] In this example, the RO type of the preamble transmission based on the SBFD aware UE is divided into the following two cases:

[0308] Case 5: The UE transmits a preamble on an additional RO;

[0309] Case 6: The UE transmits a preamble on the legacy RO.

[0310] In this example, the network side configures the seventh power offset for Case 5 and the eighth power offset for Case 6. If the power offset parameter is configured in the PUSCH-ConfigCommon IE, both the seventh and eighth power offsets are configured in that IE. If the power offset parameter is configured in the RACH-ConfigCommon IE, and that RACH configuration is a legacy RACH configuration that configures both additional RO and legacy RO, then both the seventh and eighth power offsets are configured in the IE. If the power offset parameter is configured in the RACH-ConfigCommon IE, and that RACH configuration is an additional RACH configuration that only configures additional RO, then only the seventh power offset is configured in the IE. If the power offset parameter is configured in the RACH-ConfigCommon IE, and that RACH configuration is a legacy RACH configuration that only configures legacy RO, then only the eighth power offset is configured in the IE. After the random access procedure begins, the UE needs to initialize the parameters of the above RRC configuration.

[0311] The SBFD-aware UE selects the target power offset based on the RO type of the preamble transmission. Specifically,

[0312] When an SBFD-aware UE transmits a preamble on an additional RO, regardless of whether the Msg3 PUSCH is subsequently transmitted on an SBFD symbol or a non-SBFD symbol, the target power offset is always the seventh power offset. The UE calculates the Δ power of the Msg3 PUSCH transmission. PREAMBLE_Msg3 The seventh power offset is used at that time.

[0313] When an SBFD-aware UE transmits a preamble on a legacy RO, regardless of whether the Msg3 PUSCH is subsequently transmitted on an SBFD symbol or a non-SBFD symbol, the target power offset is always the eighth power offset. The UE calculates the Δ power of the Msg3 PUSCH transmission. PREAMBLE_Msg3 The eighth power offset is used at that time.

[0314] Example 5:

[0315] Non-SBFD UEs can only transmit preambles on legacy ROs. When a base station receives a preamble from a non-SBFD UE on a legacy RO, it identifies the UE as a non-SBFD UE and can schedule Msg3PUSCH for that UE on either a non-SBFD symbol or an SBFD Flexible symbol. However, from the perspective of a non-SBFD UE, it cannot recognize SBFD Flexible symbols; all symbols are non-SBFD symbols. Therefore, the RO type for preamble transmission and the symbol type for Msg3 transmission for non-SBFD UEs only support Case 3.

[0316] In Examples 1 to 4 above, when non-SBFD transmits preamble on legacy RO and Msg3 PUSCH on non-SBFD symbols, if the network side configures a fourth power offset, the target power offset is the fourth power offset, and the UE uses the fourth power offset when calculating the Msg3 PUSCH transmission power. If the network side configures an eighth power offset, the target power offset is the eighth power offset, and the UE uses the eighth power offset when calculating the Msg3 PUSCH transmission power.
