[0040] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).
[0041] The uplink silent configuration method, apparatus, terminal, and network-side device provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0042] Currently, when NR cells are deployed on asymmetric spectrum, TDD duplex mode is typically used. In this case, TDD-UL-DL-ConfigCommon can be configured in the cell common parameters to indicate TDD frame structure information, including the TDD frame period, the number of complete downlink or uplink time slots contained in a single frame period, and the number of additional downlink or uplink symbols contained in addition to the complete downlink or uplink time slots. In addition, TDD-UL-DL-ConfigDedicated can be configured independently for each terminal using Radio Resource Control (RRC) signaling. This is used to further modify the uplink and downlink symbol configuration of one or more time slots within a single frame period based on TDD-UL-DL-ConfigCommon (i.e., the initial value of the uplink and downlink symbol configuration of the time slot is specified by TDD-UL-DL-ConfigCommon and then further modified by TDD-UL-DL-ConfigDedicated; this modification only applies to the terminal receiving this RRC signaling). However, this modification is limited to further indicating uplink or downlink symbols within the time slot (i.e., flexible symbols, which do not have a clearly defined transmission direction and can be determined later as needed for downlink or uplink transmission). It cannot modify the uplink or downlink symbols within the time slot to other directions.
[0043] The aforementioned TDD-UL-DL-ConfigCommon and / or TDD-UL-DL-ConfigDedicated are optional configurations. Since these configuration information can only be semi-statically configured or modified based on information from the RRC layer, each symbol within a single TDD frame period (combined with its configured transmission direction) determined by this configuration information is referred to below as a semi-static uplink, downlink, or flexible symbol. Symbols can be further abstracted into time-domain units, which can correspond to time slots, symbols, etc. Therefore, a single TDD frame period can contain multiple semi-static uplink, downlink, or flexible time-domain units based on the aforementioned configuration information.
[0044] When TDD-UL-DL-ConfigCommon and TDD-UL-DL-ConfigDedicated are not configured, there is no explicit concept of TDD frame period. At this time, each time slot or symbol in each radio frame of the NR cell can be understood as a semi-static flexible time domain or symbol (i.e., a semi-static flexible slot / symbol), or abstracted as a semi-static flexible time domain unit.
[0045] In addition, the base station can also indicate the slot format indicator (SFI) through dynamic signaling group common DCI (e.g., DCI 2-0); wherein, the dynamic SFI can only indicate whether the static flexible symbol is uplink, downlink or flexible, but cannot change the transmission direction of the static uplink or downlink symbol 1.
[0046] In a dynamic TDD system, adjacent cells can be configured with different TDD configurations, or different User Equipment (UE) devices within a single cell can have different TDD configurations or indications. This can lead to interference between adjacent cells (gNB to gNB) or between UEs (UE to UE). As shown in Figure 2, when gNB2 is transmitting downlink data while gNB1 is receiving uplink data, gNB1 will receive interference from gNB2. Similarly, when UE1 is transmitting uplink data while UE2 is receiving downlink data, UE2 will receive interference from UE1.
[0047] Currently, when deploying traditional cellular networks, based on available spectrum and service characteristics, Frequency Division Duplex (FDD) or Time-Division Duplex (TDD) can be used. With FDD, uplink and downlink transmissions operate on different frequencies, do not interfere with each other, and can occur simultaneously. With TDD, uplink and downlink transmissions operate on the same frequency, interleaving in a time-division manner. To more flexibly utilize limited spectrum resources, dynamically match service demands, and improve resource utilization efficiency as well as data transmission performance such as uplink coverage and latency, SBFD has been proposed. SBFD includes:
[0048] Network-side full-duplex
[0049] From the network's perspective, uplink and downlink transmissions can occur simultaneously in different frequency subbands. To avoid interference between uplink and downlink, a guard band can be reserved between the frequency subbands corresponding to different transmission directions (e.g., uplink and downlink subbands).
[0050] Terminal-side half-duplex or full-duplex
[0051] When the terminal supports half-duplex, only uplink or downlink transmission can occur at any given time; they cannot occur simultaneously. Understandably, in this case, the network side can only perform uplink or downlink transmission at any given time, or uplink and downlink transmissions at the same time can only be performed for different terminals. When the terminal supports full-duplex, similar to the network side, uplink and downlink transmissions can occur simultaneously in different frequency subbands.
[0052] For example, Figure 3 illustrates a possible schematic diagram of the SBFD method. As shown in Figure 3, the network side semi-statically divides the frequency domain of a single carrier into three sub-bands within a portion of the downlink symbols. The two sides of the carrier are the downlink sub-bands, and the center is the uplink sub-band, in order to reduce interference to adjacent carriers. The resources other than the downlink and uplink sub-bands are the Guard Band. In the third time slot, UE1 performs uplink transmission and UE2 performs downlink reception, while the base station receives data from UE1 and simultaneously transmits data to UE2.
[0053] In dynamic TDD or SBFD systems, for gNB-to-gNB interference, the covariance matrix of the interfering channel can be obtained first, and then interference cancellation can be performed based on this covariance matrix. However, to obtain the covariance matrix of the interfering channel, the terminal needs to perform uplink muting when transmitting PUSCH, that is, there should be no PUSCH or signal transmission on certain resources. However, how to configure, indicate, or enable uplink muting and the applied uplink muting pattern has become a technical problem that urgently needs to be solved.
[0054] To address the aforementioned issues, embodiments of this application provide an uplink muting configuration method, apparatus, terminal, and network-side device. The uplink muting configuration method provided in this application can be applied to scenarios where the terminal needs to perform uplink muting when transmitting PUSCH, such as scenarios requiring interference elimination between base stations.
[0055] In the uplink silence configuration method provided in this application embodiment, the terminal can receive first information related to uplink silence from the network-side device. The first information includes at least one of the following: configuration information configured for each serving cell, configuration information configured for each bandwidth part (BWP), configuration information configured for each waveform, configuration information configured for each beam, configuration information configured for Dynamic Grant (DG) PUSCH and Configured Grant (CG) PUSCH respectively, configuration information configured via higher-layer signaling, and indication information indicated by Downlink Control Information (DCI). Then, based on the first information, uplink silence-related operations are performed on the first PUSCH. Through this scheme, since the terminal can receive uplink silence-related configuration information or indication information from the network-side device, the terminal can perform uplink silence-related operations on the transmitted PUSCH (e.g., whether to perform uplink silence, or on which resources to perform uplink silence, etc.) based on the configuration information or indication information. This provides a specific scheme for configuring, indicating, or enabling uplink silence and the application of uplink silence patterns, so that the terminal can perform uplink silence when transmitting PUSCH.
[0056] This application provides an uplink silence configuration method, and Figure 4 shows a flowchart of the uplink silence configuration method provided in this application embodiment. As shown in Figure 4, the uplink silence configuration method provided in this application embodiment may include the following steps 401 and 402.
[0057] Step 401: The terminal receives the first information related to uplink silence from the network-side device.
[0058] The first information mentioned above includes at least one of the following: configuration information configured for each serving cell, configuration information configured for each BWP, configuration information configured for each waveform, configuration information configured for each beam, configuration information configured for DG PUSCH and CG PUSCH respectively, configuration information configured via higher-layer signaling, and indication information indicated by DCI.
[0059] Optionally, in this embodiment of the application, the configuration information configured for each serving cell can be the information configured by the network-side device in IE PUSCH-ServingCellConfig.
[0060] Optionally, in this embodiment of the application, the configuration information configured for each BWP (i.e., per BWP) can be the information configured by the network-side device in IE BWP-UplinkDedicated.
[0061] Optionally, in this embodiment of the application, when the first information is the configuration information configured for each waveform, the network-side device can configure Cyclic Prefix (CP)-Orthogonal Frequency Division Multiplexing (OFDM) waveforms (conversion precoding is not enabled) and Discrete Fourier Transform (DFT)-S-OFDM waveforms (conversion precoding is enabled).
[0062] Optionally, in this embodiment of the application, the configuration information configured for DG PUSCH and CG PUSCH respectively can be the information configured by the network-side device in IE PUSCH-config and ConfiguredGrantConfig respectively.
[0063] Optionally, in this embodiment, for the first PUSCH being a PUSCH activated after CG PUSCH type 1 and CG PUSCH type 2 (optionally, the first PUSCH does not include the PUSCH within the first cycle after activation), the aforementioned first information can be the configuration information in ConfiguredGrantConfig; for the first PUSCH being a PUSCH within the first cycle after CG PUSCH type 2 activation and a PUSCH dynamically scheduled by DCI, the aforementioned first information can be the configuration information in PUSCH-config; for the first PUSCH being a CG PUSCH retransmission, the aforementioned first information can be the configuration information in PUSCH-config or ConfiguredGrantConfig. Optionally, the aforementioned first information can be the configuration information in PUSCH-config.
[0064] Optionally, in this embodiment of the application, when the first information is the configuration information configured for each waveform (i.e., per beam), the network-side device can configure at least one of the following for each waveform: uplink muting pattern (i.e., UL muting pattern), whether to enable uplink muting (i.e., UL muting), and the condition for enabling uplink muting. The terminal can determine whether the PUSCH should be muted uplink or the uplink muting pattern applied based on the waveform corresponding to the scheduled PUSCH.
[0065] Optionally, in this embodiment, when the first information is configuration information for each beam configuration, the network-side device configures the uplink silence style and / or whether to enable uplink silence for each TCI state when configuring the Transmission Configuration Indicator (TCI) state. The network-side device configures the TCI state used for PUSCH transmission through higher-layer configuration or DCI, and the terminal determines whether the PUSCH should be uplink silenced or whether an uplink silence style should be applied based on the correspondence between the TCI state and uplink silence. Alternatively, when configuring spatial relation information, the network-side device configures the uplink silence style and / or whether to enable uplink silence for each spatial relation. The network-side device configures the spatial relation used for PUSCH transmission through higher-layer configuration or DCI, and the terminal determines whether the PUSCH should be uplink silenced or whether an uplink silence style should be applied based on the correspondence between the spatial relation and uplink silence.
[0066] Optionally, in the embodiments of this application, for multi-transmit / receive point (TRP) scenarios, for PUSCH using Space Division Multiplexing (SDM) mode, for example, the parameter multipanelScheme is set to 'SDMscheme' and associated with the first TCI state or the second TCI state respectively (the PUSCH transmission timing scheduled or activated by DCI format 0_1 or 0_2 is related to the first indicated TCI-States or TCI-UL-States, and to the second indicated TCI-States or TCI-UL-States respectively), the terminal expects the first TCI state or the second TCI state to be associated with the same uplink silence pattern, or associated with the same number of uplink silence patterns, or the same number of silenced uplink symbols, or the same uplink silence enable or disable status.
[0067] Optionally, in this embodiment of the application, for a PUSCH that is rolled back to DCI scheduling or activated, or a CG PUSCH of type 1, the first information mentioned above may be configuration information configured through higher-layer signaling; or, for a PUSCH that is not rolled back to DCI scheduling or activated, the first information mentioned above may be indication information indicated by DCI.
[0068] Optionally, in this embodiment of the application, when the first information is an indication information indicated by DCI, the network-side device configures one or more uplink silencing styles through higher-layer signaling (e.g., RRC). (Optionally, the network-side device may include disabling uplink silencing when configuring the uplink silencing style.) The network-side device indicates which uplink silencing style the scheduled PUSCH adopts or whether uplink silencing is applied (i.e., enabling or disabling uplink silencing) through the DCI of the scheduled PUSCH.
[0069] Optionally, in this embodiment, the aforementioned first information can be indicated by the Time Domain Resource Assignment (TDRA) field in the DCI. Specifically, when configuring the TDRA table through higher-layer signaling, the network-side device configures whether uplink silencing is enabled and / or the applied uplink silencing style for each row of the TDRA table. That is, for each row of the TDRA, the base station can configure K2, SLIV (i.e., length indicator), mapping type, whether uplink silencing is enabled or which uplink silencing style is applied, etc. (Optionally, the number of repetitions can also be configured). The TDRA field in the DCI indicates a row index in the TDRA table configured by higher-layer signaling, and thus can indicate the uplink silencing related information corresponding to the PUSCH scheduled by the DCI.
[0070] Optionally, in this embodiment of the application, when the first information is configuration information configured through higher-layer signaling, the terminal can determine whether a certain PUSCH is enabled for uplink silencing or which uplink silencing style is applied according to predefined rules.
[0071] For example, when a PUSCH transmission symbol overlaps with an SFBD symbol (including full or partial overlap), uplink muting is enabled; otherwise, uplink muting is disabled. When the number of PUSCH symbols is greater than X, uplink muting is enabled; otherwise, uplink muting is disabled. Here, X can be configured or indicated directly or implicitly (e.g., through the first symbol index) by the network-side device, or it can be specified by the protocol, such as 7. When a PUSCH transmission symbol overlaps with the first symbol index, uplink muting is enabled; otherwise, uplink muting is disabled.
[0072] Optionally, in this embodiment of the application, the first information mentioned above may be configuration information configured through higher-layer signaling.
[0073] The configuration information configured through higher-level signaling includes information on at least one uplink silence style.
[0074] For example, when at least one of the above-mentioned uplink silence styles includes at least two uplink silence styles, each uplink silence style may correspond to a different symbol position and / or a different frequency domain position.
[0075] Optionally, in this embodiment of the application, the configuration information of the above-mentioned at least one uplink silence style may include at least one applied uplink silence style.
[0076] In this embodiment of the application, since one or more uplink silence configuration information can be configured when the first information can be configured through higher-layer signaling, the flexibility of determining the first information can be improved.
[0077] Optionally, in the embodiments of this application, the aforementioned first information may be used for at least one of the following 1.1 to 1.8:
[0078] 1.1 Enable uplink silence;
[0079] 1.2. Enable upward silence;
[0080] 1.3 Configure the uplink silent style;
[0081] 1.4 Indicates the upward silent style;
[0082] 1.5 Configure the conditions for enabling uplink silence;
[0083] 1.6. Indicates the conditions that enable uplink silence;
[0084] 1.7 Configure the conditions to disable uplink silence;
[0085] 1.8 Instructions to enable the conditions for upward silence.
[0086] Optionally, in this embodiment of the application, the condition for enabling uplink silencing can be: the number of symbols in the PUSCH is greater than X; that is, uplink silencing is applied only for PUSCHs with a symbol count greater than X. Here, X can be configured by the network-side device.
[0087] Optionally, in the embodiments of this application, the condition for enabling uplink silence can be: the PUSCH priority is high; that is, uplink silence is applied only for high-priority PUSCHs.
[0088] Optionally, in this embodiment, the condition for enabling uplink muting can be: the PUSCH is not involved in the random access procedure. For retransmissions of PUSCH involved in the random access procedure, such as msg A PUSCH, msg 3 PUSCH, or msg A PUSCH or msg 3 PUSCH, uplink muting is not enabled.
[0089] Optionally, in this embodiment, the condition for enabling uplink muting can be: the PUSCH is a PUSCH scheduled or activated by a connected UE. For non-connected PUSCHs, such as PUSCH for small data, uplink muting is not enabled.
[0090] In this embodiment of the application, since the first information can be used for at least one of 1.1 to 1.8, different information related to uplink silence can be configured or indicated through the first information, so that the terminal can perform uplink silence-related operations according to the first information.
[0091] Optionally, in embodiments of this application, the aforementioned first information may include at least one of the following 2.1 to 2.7:
[0092] 2.1 The frequency domain location corresponding to uplink silence;
[0093] 2.2 The time domain location corresponding to uplink silence;
[0094] 2.3 The period corresponding to upward silence;
[0095] 2.4. Offset value within the period corresponding to upward silence;
[0096] 2.5. Apply the uplink silence time unit;
[0097] 2.6 Apply uplink silent PUSCH;
[0098] 2.7. Silent style for upward movement.
[0099] Optionally, in the embodiments of this application, the frequency domain position corresponding to the above-mentioned uplink silence may include a comb index, such as comb 0 or comb 1.
[0100] In this context, the position corresponding to the first PRB of combo 0 can be the lowest PRB in the frequency domain allocated resources for the scheduled or activated PUSCH (such as the first PUSCH mentioned above), or it can be the lowest PRB in the frequency domain of the ULBWP, UL subband, serving cell, or carrier corresponding to the scheduled or activated PUSCH (such as the first PUSCH mentioned above), or it can be point A of the serving cell corresponding to the scheduled or activated PUSCH (such as the first PUSCH mentioned above). Uplink silence adopts a combo 2 structure, which divides the frequency domain PRBs into two combos. The interval between adjacent PRBs in each combo is one PRB, i.e., every other PRB. It can be understood that the combo 2 structure for uplink silence can be based on the frequency domain resource allocation of the scheduled or activated PUSCH, or based on the UL BWP, UL subband, serving cell, carrier, or a reference point (such as point A) where the PUSCH is located.
[0101] For example, as shown in Figure 12, when the position corresponding to the first PRB of combo 0 is the lowest PRB with allocated frequency domain resources for the scheduled or activated PUSCH (such as the first PUSCH mentioned above), if the uplink silence index is configured as combo 0, for each PUSCH, the UE determines the position of the PRB corresponding to combo 0 based on the frequency domain resources allocated to each PUSCH. The PRB position corresponding to uplink silence may differ under different PUSCH frequency domain resource allocations.
[0102] For example, as shown in Figure 13, when the position corresponding to the first PRB of comb 0 is the lowest frequency PRB of the UL BWP, UL subband, serving cell, or carrier corresponding to the scheduled or activated PUSCH (such as the first PUSCH mentioned above), or the point A of the serving cell corresponding to the scheduled or activated PUSCH (such as the first PUSCH mentioned above), if the uplink silencing index is configured as comb 0, the position of the PRB corresponding to this comb is independent of the position of the scheduled PUSCH. For each PUSCH, if uplink silencing is enabled, the UE can obtain the PRB that needs to be uplink silenced in the PUSCH resource allocation by taking the intersection of the PRB corresponding to the comb and the PRB allocated to the PUSCH.
[0103] Optionally, in this embodiment of the application, if the time domain corresponding to the uplink silence contains two symbols, the frequency domain positions on different symbols can be different. For example, the base station can configure the comb index of the uplink silence corresponding to the two symbols respectively.
[0104] Optionally, in this embodiment of the application, the time domain position corresponding to the above-mentioned uplink silence may include a first symbol index, or may include a first symbol index and a second symbol index.
[0105] Optionally, in this embodiment of the application, the time domain position corresponding to the above-mentioned uplink silence may include a first symbol index.
[0106] The first symbol index mentioned above includes any one of the following:
[0107] The symbol index relative to the starting position of the time unit in which the scheduled or activated PUSCH is located;
[0108] The symbolic index relative to the starting position of the scheduled or activated PUSCH;
[0109] The symbolic index relative to the starting position of each actual repetition of a scheduled or activated PUSCH.
[0110] The symbolic index relative to the starting position of each nominal repetition (i.e., normal repetition) of the scheduled or activated PUSCH;
[0111] The symbol index relative to the starting symbol of each hop of the scheduled or activated PUSCH;
[0112] The symbol index relative to the starting position of the time unit where the first PUSCH is located;
[0113] The symbol index relative to the starting position of the first PUSCH mentioned above;
[0114] The symbol index relative to the starting position of each actual repetition of the first PUSCH mentioned above;
[0115] The symbol index relative to the starting position of each nominal repetition of the first PUSCH mentioned above;
[0116] The symbol index relative to the starting symbol of each hop of the first PUSCH mentioned above.
[0117] Optionally, in this embodiment of the application, the PUSCH that is scheduled or activated may be the first PUSCH.
[0118] Optionally, in the embodiments of this application, the aforementioned time unit may be a time slot or a sub-time slot, etc.
[0119] Optionally, in this embodiment of the application, when the repetition type of the first PUSCH is PUSCH repetition type B, the first symbol index may be a symbol index relative to the starting position of each actual or nominal repetition of the first PUSCH.
[0120] Optionally, in the embodiments of this application, the first symbol index may be determined based on at least one of the following: whether the first PUSCH is enabled for frequency hopping, the PUSCH mapping type used by the first PUSCH, whether the scheduled or activated PUSCH is enabled for frequency hopping, and the PUSCH mapping type used by the scheduled or activated PUSCH.
[0121] For example, if the first symbol index is determined based on whether the first PUSCH is enabled for frequency hopping, then if the first PUSCH is not enabled for frequency hopping, the first symbol index can be the symbol index relative to the start position of the time unit in which the first PUSCH is located; if the first PUSCH is enabled for frequency hopping, then the first symbol index can be the symbol index relative to the start symbol of each hop of the first PUSCH.
[0122] For example, taking the first symbol index as determined based on the PUSCH mapping type used by the first PUSCH, if the PUSCH mapping type used by the first PUSCH is PUSCH mapping type A, then the first symbol index can be the symbol index relative to the starting position of the time unit where the first PUSCH is located, or the symbol index relative to the starting symbol of each hop of the first PUSCH; if the PUSCH mapping type used by the first PUSCH is PUSCH mapping type B, then the first symbol index can be the symbol index relative to the starting position of the first PUSCH, or the symbol index relative to the starting symbol of each hop of the first PUSCH.
[0123] In this embodiment of the application, since the first symbol index can be determined based on at least one of whether the first PUSCH is enabled for frequency hopping and the PUSCH mapping type adopted by the first PUSCH, the flexibility in determining the first symbol index can be improved.
[0124] Optionally, in this embodiment of the application, the time unit for the application uplink silence can be the uplink silence time slot indicated by a bitmap.
[0125] It should be noted that the number of time slots contained in the bitmap above can be a period, meaning the number of time slots in the period is determined by the number of bits in the bitmap. This allows the terminal to periodically determine whether uplink silence should be applied within each time slot.
[0126] Optionally, in the embodiments of this application, the above-mentioned application uplink silent PUSCH can be DG PUSCH only, high priority PUSCH, PUSCH with symbol length meeting specific requirements, or PUSCH of non-random access procedure, etc.
[0127] The PUSCH of the random access procedure includes at least one of the following: PUSCH scheduled by RAR UL grant or fallback RAR UL grant, PUSCH scheduled by TC-RNTI, Msg A PUSCH, Msg 3 PUSCH, retransmission of Msg A PUSCH, and retransmission of Msg 3 PUSCH.
[0128] In this embodiment of the application, since the first information mentioned above may include at least one of 2.1 to 2.7, the terminal can receive information of different dimensions related to uplink silence, thereby flexibly performing uplink silence-related operations.
[0129] Step 402: Based on the first information, the terminal performs uplink silent related operations on the first PUSCH.
[0130] Optionally, in the embodiments of this application, the first PUSCH described above may satisfy at least one of the following 3.1 to 3.6:
[0131] 3.1 The symbol length meets specific conditions;
[0132] 3.2 The PUSCH demodulation reference signal mapping type used is the first mapping type;
[0133] 3.3 The transmission location overlaps with the SBFD symbol;
[0134] 3.4 The Radio Network Temporary Identity (RNTI) used is a specific RNTI;
[0135] 3.5. DCI scheduling or activated PUSCH for scrambling specific RNTIs;
[0136] 3.6, for CG PUSCH.
[0137] Optionally, in the embodiments of this application, the above-mentioned specific condition can be greater than or equal to a preset symbol length.
[0138] Optionally, in this embodiment of the application, the first mapping type can be PUSCH DMRS mapping type A.
[0139] Optionally, in the embodiments of this application, the specific RNTI mentioned above can be C-RNTI, MCS-RNTI or CS-RNTI.
[0140] Optionally, in this embodiment of the application, for PUSCH that does not satisfy at least one of 3.1 to 3.6 above, the first information is not applied and the uplink silence-related operation is not performed.
[0141] In this embodiment of the application, since the first PUSCH satisfies at least one of 3.1 to 3.4 above, uplink silencing related operations can be performed only on specific PUSCHs, thereby avoiding uplink silencing related operations on all PUSCHs. This can reduce the impact of uplink silencing, such as unreasonable TBS, excessive code rate, ambiguity between base station and UE, uplink resource utilization, etc.
[0142] Optionally, in this embodiment of the application, when the first information indicates that uplink silence is enabled, the terminal can enable uplink silence for the first PUSCH based on the first information.
[0143] Optionally, in this embodiment of the application, when the first information indicates that uplink muting should be disabled, the terminal can disable uplink muting for the first PUSCH based on the first information, that is, not perform uplink muting.
[0144] Optionally, in this embodiment of the application, when the first information is used to configure or indicate the uplink silence style, the terminal can determine the uplink silence style of the first PUSCH application based on the first information.
[0145] Optionally, in this embodiment of the application, when the first information is used to configure or indicate the conditions for uplink silence, the terminal can determine whether to enable uplink silence for the first PUSCH based on the uplink silence conditions configured or indicated by the first information.
[0146] Optionally, in this embodiment of the application, when the first information is used to configure or indicate the conditions for de-silencing uplink, the terminal can determine whether to de-silence uplink on the first PUSCH based on the conditions for de-silencing uplink configured or indicated by the first information.
[0147] In the uplink silence configuration method provided in this application, since the terminal can receive configuration information or indication information related to uplink silence from the network-side device, the terminal can perform uplink silence-related operations on the transmitted PUSCH based on the configuration information or indication information (e.g., whether to perform uplink silence, or on which resources to perform uplink silence, etc.). This provides a specific scheme for configuring, indicating, or enabling uplink silence and the application of uplink silence patterns, so that the terminal can perform uplink silence when transmitting PUSCH.
[0148] Optionally, in this embodiment, the first PUSCH may include any of the following: a PUSCH repeating in a repeating PUSCH, a PUSCH in a multi-PUSCH scheduling, or a PUSCH in a Transport Block over Multi-Slot (TBoMS). Exemplarily, prior to step 402 above, the uplink silent configuration method provided in this embodiment may further include step 403 below.
[0149] Step 403: Based on the second information, the terminal determines whether the first PUSCH applies uplink silence or an applied uplink silence style.
[0150] The second piece of information mentioned above includes at least one of the following:
[0151] The time unit type of the first PUSCH mentioned above, and the time domain resources of the first PUSCH configured or indicated by the first information mentioned above;
[0152] Conditions that enable uplink silence;
[0153] The TCI state or spatial relationship associated with the first PUSCH mentioned above;
[0154] The indication of the first DCI, wherein the first DCI is the scheduling DCI or activation DCI corresponding to the first PUSCH, the indication of the first DCI is used to indicate at least one of the following: whether to apply uplink silence to all PUSCHs or PUSCH repeats scheduled by the scheduling DCI, whether to apply uplink silence to all PUSCHs or PUSCH repeats activated by the activation DCI, the uplink silence style applied to all PUSCHs or PUSCH repeats scheduled by the scheduling DCI, the uplink silence style applied to all PUSCHs or PUSCH repeats activated by the activation DCI, the first PUSCH or PUSCH repeat to which uplink silence is applied, whether to apply uplink silence to the first PUSCH or PUSCH repeat that meets the conditions for enabling uplink silence, and the uplink silence style applied to the first PUSCH or PUSCH repeat that meets the conditions for enabling uplink silence.
[0155] Optionally, in this embodiment of the application, when the second information includes the time unit type of the first PUSCH and the time domain resource of the first PUSCH configured or indicated by the first information, the terminal can determine whether the first PUSCH should apply uplink silence based on whether the time unit of the first PUSCH overlaps with the time domain resource configured or indicated by the first information.
[0156] For example, if the time unit for applying uplink silence is configured by RRC (e.g., the time slot for applying uplink silence is periodically indicated by bitmap as mentioned above), then the terminal can determine the time unit for applying uplink silence and the time unit where each PUSCH repetition or PUSCH is located based on the uplink silence configuration, and thus determine whether the first PUSCH should apply uplink silence.
[0157] Optionally, in this embodiment, the condition for enabling uplink silence may be configured or indicated by the first information, or it may be predefined. Optionally, in this embodiment, when the second information includes the condition for enabling uplink silence, the terminal can determine whether the first PUSCH is enabled for uplink silence based on whether the first PUSCH meets the condition for enabling uplink silence.
[0158] For example, assuming that the condition for enabling uplink silence is that the length of each actual repeat and nominal repeat in the PUSCH is greater than or equal to L, the terminal can determine whether the length of each actual repeat and nominal repeat in the first PUSCH is greater than or equal to L; if the length of each actual repeat and nominal repeat in the first PUSCH is greater than or equal to L, then the terminal determines that the first PUSCH enables uplink silence; otherwise, the terminal determines that the first PUSCH does not enable uplink silence.
[0159] Optionally, in this embodiment of the application, when the second information includes the TCI status or spatial relationship associated with the first PUSCH, the terminal can determine whether the first PUSCH applies uplink silence or the applied uplink silence style based on the association between the TCI status or spatial relationship associated with the first PUSCH and uplink silence.
[0160] In this embodiment of the application, for cases of repeated PUSCH transmission (such as PUSCH configured or indicated to be repeated), multi-PUSCH scheduling (such as multi-PUSCH scheduling, i.e., one DCI schedules multiple PUSCH transmissions, and multiple PUSCHs are used to transmit different TBs) or TBoMS (i.e., TB over multiple slots, for example, one DCI schedules multiple PUSCHs to transmit in different time slots, and multiple PUSCHs are used to transmit one TB), the terminal can determine whether each PUSCH is repeated or whether each PUSCH applies uplink silence or the applied uplink silence style based on the above-mentioned second information. Therefore, uplink silence and the applied uplink silence style can be configured, indicated or enabled in different scenarios, thereby eliminating interference between base stations in different scenarios.
[0161] The uplink silent configuration method provided in the embodiments of this application will be described exemplarily below with reference to the accompanying drawings.
[0162] For example, Figure 5 illustrates the time-domain location configuration of the uplink demodulation reference signal (DMRS) symbols and uplink muting symbols (i.e., UL muting symbols) within a time slot (taking one PRB in the frequency domain as an example). As shown in Figure 5, the PUSCH mapping type is type A, and the UL DMRS are symbols 1 and 12 within the time slot (symbol 0 represents the first symbol within the time slot). The UL muting pattern time-domain location includes two symbols, symbol 2 and symbol 9.
[0163] In one implementation, the network-side device configures the UL muting pattern as follows: UL-muting-pattern{ UL-muting-patternID MutingpatternFre ENUMERATED{comb0,comb1} MutingpatternTime1 INTEGER(0..13) MutingpatternTime2 INTEGER(0..13)OPTIONAL}
[0164] The `MutingpatternFre` parameter configures the frequency domain position of the UL muting pattern, while `MutingpatternTime1` or `MutingpatternTime2` configures the time domain position. The time domain position must contain at least one symbol and at most two symbols; that is, `MutingpatternTime2` can be omitted. If the network-side device configures `MutingpatternTime2`, it indicates that the time domain contains two symbols, and the frequency domain position of the UL muting is the same in both symbols. For `MutingpatternTime1` or `MutingpatternTime2`, the value is an integer from 0 to 13, representing the time domain symbol position of the UL muting. It can be a symbol number relative to the start position of the time slot. In another implementation, `MutingpatternTime2` represents the number of symbols offset by the second silent symbol relative to the first silent symbol. For example, 2 represents the third symbol within the time slot. In this method, the time domain position (at least the first symbol position) in the silent mode is relative to the start position of the time slot. The advantage is that when the PUSCH DMRS symbol is relative to the start position of the time slot, it is convenient for network-side devices to avoid the UL muting symbol from overlapping with the UL DMRS or PTRS symbol through configuration.
[0165] Another approach is to use the time-domain symbol relative to the starting position of the scheduled PUSCH. The advantage of this approach is that when the PUSCH DMRS symbol is relative to the starting position of the scheduled PUSCH, it is easier for network-side devices to avoid the overlap between the UL muting symbol and the UL DMRS symbol through configuration.
[0166] Another approach is to use the starting position relative to each hop of the scheduled PUSCH. The advantage of this approach is that when frequency hopping is enabled on the PUSCH, it is easier for network-side devices to avoid overlap between UL muting symbols and UL DMRS symbols through configuration.
[0167] Of course, whether MutingpatternTime1 or MutingpatternTime2 represents the start position relative to the time slot, the start position of the scheduled PUSCH, or the start position of each hop of the scheduled PUSCH can be determined based on the PUSCH mapping type, whether PUSCH frequency hopping is enabled, or the symbol length of the PUSCH. For example, if the PUSCH uses PUSCH mapping type A, then when PUSCH frequency hopping is not enabled, it is relative to the start position relative to the time slot; if PUSCH frequency hopping is enabled, then it is relative to the start position of each PUSCH hop. If the PUSCH uses PUSCH mapping type B, then when PUSCH frequency hopping is not enabled, it is relative to the start position relative to the scheduled / configured PUSCH; if PUSCH frequency hopping is enabled, then it is relative to the start position of each PUSCH hop. Optionally, this PUSCH frequency hopping is intra-slot frequency hopping.
[0168] In related technologies, the DCI (Distributed Control Interface) for scheduling PUSCHs includes a TDRA (Time Domain Representation) field, used to indicate the temporal resource allocation for PUSCH scheduling. The TDRA field in the DCI indicates a row index in the RRC (Resource Control Code) configuration or protocol-predefined TDRA table. Each row in the network-side device configuration or protocol-predefined TDRA table can contain information such as K2 and SLIV mapping type. To dynamically enable or indicate the UL muting pattern, the TDRA table can be extended; for example, a new column can be added to the TDRA table to indicate whether UL muting is enabled or to indicate the corresponding UL muting pattern. It can be understood that if UL muting is not configured, it means that the UL muting in the corresponding TDRA row is disabled.
[0169] For example, the TDRA table can be configured with the following information, as shown in Table 1 below:
[0170] Table 1
[0171] Optionally, k2 (timing from DCI to PUSCH), mapping type, and SLIV (start symbol and symbol length) can be configured in IE PUSCH-TimeDomainResourceAllocation; or each row in the TDRA table configured in IE PUSCH-TimeDomainResourceAllocation-r16 can contain k2, mapping type, SLIV or start symbol and symbol length, repetition count, TBoMS slot number, extension k2, etc.; thus, without adding bit fields in DCI, the PUSCH can be dynamically indicated by scheduling the PUSCH to determine whether UL muting or UL muting style is enabled, thereby improving the flexibility of indication.
[0172] Optionally, the IE can be extended to configure whether UL muting and / or the corresponding muting pattern are enabled. For example, the base station configures at least one UL-muting-pattern according to the IE UL-muting-patternList in the example above. UL-muting-patternList::=SEQUENCE(1,maxNrof UL-muting-pattern)OF UL-muting-pattern.
[0173] In related technologies, network-side devices can configure or indicate the TCI state used for PUSCH transmission. For example, if a unified TCI state is configured, the network-side device can indicate the TCI state adopted by the UE in the DL DCI (e.g., the Transmission Configuration Indication field). For instance, after the DL DCI indication, the UE sends an ACK, and after a predefined delay, the PUCCH or PUSCH will adopt the TCI state indicated by that DCI. Alternatively, if a unified TCI state is not configured, the network-side device can indicate (e.g., the SRS resource indicator) in the DCI for scheduling PUSCH, such as DCI format 0_1 / 0_2, indicating which spatial relation the PUSCH uses.
[0174] Optionally, when configuring TCI state or spatial relation information, the network-side device configures the UL muting pattern associated with each TCI state or spatial relation information (such as UL muting enable, UL-muting-pattern1, UL-muting-pattern2, etc.). The terminal determines whether the UL muting corresponding to the PUSCH is enabled or the corresponding UL muting pattern based on the TCI state or spatial relation indicated or configured by the network-side device. Optionally, when the PUSCH is configured to use 'SDMscheme', two PUSCHs scheduled by a DCI can use different TCI states or spatial relations. In this case, the terminal expects the UL muting associated with these two TCI states or spatial relations to meet certain conditions, such as either both having UL muting enabled, or neither having UL muting enabled, or having the same UL muting pattern, or having the same number of time-domain muted symbols in the UL muting pattern, etc.
[0175] This application provides another uplink silence configuration method. Figure 6 shows a flowchart of the uplink silence configuration method provided in this application embodiment. As shown in Figure 6, the uplink silence configuration method provided in this application embodiment may include the following step 601.
[0176] Step 601: The network-side device sends the first information related to uplink silence to the terminal.
[0177] The first information mentioned above includes at least one of the following: configuration information configured for each serving cell, configuration information configured for each BWP, configuration information configured for each waveform, configuration information configured for each beam, configuration information configured for DG PUSCH and CG PUSCH respectively, configuration information configured via higher-layer signaling, and indication information indicated by DCI.
[0178] Optionally, in this embodiment of the application, for a PUSCH that is rolled back to DCI scheduling or activated, or a CG PUSCH of type 1, the first information mentioned above may be configuration information configured through higher-layer signaling; or, for a PUSCH that is not rolled back to DCI scheduling or activated, the first information mentioned above may be indication information indicated by DCI.
[0179] Optionally, in this embodiment of the application, the first information mentioned above may be configuration information configured through higher-layer signaling.
[0180] The configuration information configured through higher-level signaling includes at least one type of uplink silence configuration information.
[0181] Optionally, in the embodiments of this application, the aforementioned first information can be used for at least one of the following:
[0182] Enables uplink silence;
[0183] To enable upward silence;
[0184] Configure the uplink silent style;
[0185] Indicates the uplink silent style;
[0186] Configure the conditions to enable uplink silence;
[0187] Indicates the conditions that enable uplink silence;
[0188] Configure the conditions to disable uplink silence;
[0189] Instructions to enable the conditions for uplink silence.
[0190] Optionally, in embodiments of this application, the aforementioned first information may include at least one of the following:
[0191] Upward silence style;
[0192] The frequency domain position corresponding to uplink silence;
[0193] The time domain position corresponding to uplink silence;
[0194] The period corresponding to the upward silence;
[0195] The offset value within the period corresponding to the uplink silence;
[0196] Apply the uplink silence time unit;
[0197] Apply uplink silent PUSCH.
[0198] Optionally, in this embodiment of the application, the time domain position corresponding to the above-mentioned uplink silence may include a first symbol index.
[0199] The first symbol index mentioned above includes any one of the following:
[0200] The symbol index relative to the starting position of the time unit in which the scheduled or activated PUSCH is located;
[0201] The symbolic index relative to the starting position of the scheduled or activated PUSCH;
[0202] The symbolic index relative to the starting position of each actual repetition of the scheduled or activated PUSCH;
[0203] The symbol index relative to the starting position of each nominal repetition of the scheduled or activated PUSCH;
[0204] The symbol index relative to the starting symbol of each hop of the scheduled or activated PUSCH;
[0205] The symbol index relative to the starting position of the time unit where the first PUSCH is located;
[0206] The symbol index relative to the starting position of the first PUSCH mentioned above;
[0207] The symbol index relative to the starting position of each actual repetition of the first PUSCH mentioned above;
[0208] The symbol index relative to the starting position of each nominal repetition of the first PUSCH mentioned above;
[0209] The symbol index relative to the starting symbol of each hop of the first PUSCH mentioned above.
[0210] Optionally, in the embodiments of this application, the first symbol index may be determined based on at least one of the following: whether the first PUSCH is enabled for frequency hopping, the PUSCH mapping type used by the first PUSCH, whether the scheduled or activated PUSCH is enabled for frequency hopping, and the PUSCH mapping type used by the scheduled or activated PUSCH.
[0211] In the uplink muting configuration method provided in this application, since the network-side device can send configuration information or indication information related to uplink muting to the terminal, the terminal can perform uplink muting-related operations on the transmitted PUSCH based on the configuration information or indication information (e.g., whether to perform uplink muting, or on which resources to perform uplink muting, etc.). This provides a specific scheme for configuring, indicating, or enabling uplink muting and the application of uplink muting patterns, so that the terminal can perform uplink muting when transmitting PUSCH, enabling the network-side device to obtain the covariance matrix of the interference channel to eliminate interference between base stations.
[0212] The uplink silent configuration method provided in this application can be executed by an uplink silent configuration device. This application uses the example of an uplink silent configuration device executing the uplink silent configuration method to illustrate the uplink silent configuration device provided in this application.
[0213] This application provides an uplink silence configuration device. As an example, the uplink silence configuration device can be a communication device or a component within a communication device, such as a chip. The communication device can be a terminal, a network-side device, or a server, etc. Exemplarily, the terminal can be, but is not limited to, the type of terminal 11 listed above, and the network-side device can be, but is not limited to, the type of network-side device 12 listed above. This application does not impose specific limitations.
