Description
Technical Field
[0001] This application relates to the field of communication technology, and in particular to a transmission configuration method and apparatus. Background Technology
[0002] In the New Radio (NR) RedCap (Reduced Capability) scenario, the terminal supports Frequency Division Duplex (FDD) mode, Time Division Duplex (TDD) mode, and Half-Duplex FDD mode.
[0003] In half-duplex FDD mode, the terminal cannot transmit and receive simultaneously. Currently, in terrestrial systems, due to the close distance between the base station and the terminal, and the fact that the base station can know the actual timing advance used by the terminal, uplink and downlink collisions between the base station and the terminal are predictable.
[0004] However, in non-terrestrial networks (NTNs), since the transmission delay between satellites and terminals is estimated and pre-compensated by the terminals, the base station cannot know the actual timing advance used by the terminals.

[0129] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.
[0130] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.
[0131] The technical solutions provided in this application can be applied to various systems, such as 5G systems.
[0132] The terminal involved in this application embodiment 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. The name of the terminal may differ in different systems; for example, in a 5G system, the terminal can be called a 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. They exchange voice and / or data with the radio access network. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments of this application.
[0133] 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. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a NodeB in a Wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of this application. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.
[0134] For example, in the embodiments of this application, the network device and the terminal device can each use one or more antennas to perform multiple input multiple output (MIMO) transmission. MIMO transmission can be single user MIMO (SU-MIMO) or multiple user MIMO (MU-MIMO). Depending on the shape and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or it can be diversity transmission, precoding transmission, or beamforming transmission, etc.
[0135] In half-duplex FDD mode, the terminal cannot transmit and receive simultaneously. Currently, in terrestrial systems, due to the close distance between the base station and the terminal, and the fact that the base station can know the actual timing advance (TA) used by the terminal, uplink and downlink collisions between the base station and the terminal are predictable.
[0136] However, in NTN, since the transmission delay between the satellite and the terminal is estimated and pre-compensated by the terminal, the base station cannot know the actual timing advance used by the terminal. This can lead to uplink and downlink collisions on the terminal side due to unreasonable transmission configuration of the base station.
[0137] To effectively address the issue of uplink and downlink collisions at the terminal side caused by unreasonable base station transmission configuration, this application provides a transmission configuration method. The technical solutions described below, in conjunction with the embodiments and related drawings, will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0138] Figure 1 This application provides a flowchart illustrating a method for determining a transmission configuration, applicable to network devices such as base stations. For example, please refer to [link to relevant documentation]. Figure 1 As shown, the method may include:
[0139] S101, the timing of the receiving terminal's report is advanced.
[0140] For example, in the embodiments of this application, the advance timing can be the advance timing of the most recent report submitted by the terminal, or the advance timing of the previous report submitted most recently, etc., and can be set according to actual needs.
[0141] S102. Determine the target time period in advance based on the timing, and configure the terminal to perform transmission operations outside the target time period.
[0142] The target time period can be understood as an ambiguous period, during which the network device cannot know whether the terminal is transmitting uplink (UL) or receiving downlink (DL).
[0143] Once the target time period is determined, since the network device cannot know whether the terminal is transmitting uplink or receiving downlink during the target time period, the network device is configured not to perform other transmission operations during the target time period. In other words, the terminal is configured to perform other transmission operations outside the target time period.
[0144] As can be seen, in this embodiment of the application, the network device receives the timing advance reported by the terminal, determines the target time period based on the timing advance, and configures the terminal to perform transmission operations outside the target time period. This allows for targeted transmission configuration, which can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0145] Based on the above Figure 1 The illustrated embodiment, for example, when determining the target time period in advance based on a timer in S102 above, can include at least three possible scenarios:
[0146] In one possible scenario, one of the uplink transmissions and the other of the downlink receptions is semi-statically configured, while the other is dynamically scheduled.
[0147] For example, in this possible scenario, there are two cases: one is that the uplink transmission is semi-static, i.e., semi-static UL configuration, and the downlink reception is dynamically scheduled, i.e., dynamic DL configuration; the other is that the uplink transmission is dynamically scheduled, i.e. dynamic UL configuration, and the downlink reception is semi-static, i.e. semi-static DL configuration.
[0148] In one scenario, uplink transmission is semi-statically configured, while downlink reception is dynamically scheduled. When the target time period is determined based on timing advance, a first time period before the transmission of the start symbol can be determined based on the uplink transmission timing advance, a preset timing threshold offset value, and the transition time from downlink reception to uplink transmission at the terminal; and a second time period after the end of symbol transmission can be determined based on the uplink transmission timing advance, the timing threshold offset value, and the transition time from uplink transmission to downlink reception at the terminal; wherein the target time period includes the first and second time periods, and the transmission operation is downlink reception.
[0149] The first time period can be understood as an ambiguous period before the terminal sends the start symbol, and the second time period can be understood as an ambiguous period after the terminal finishes sending the symbol. During these two ambiguous periods, the network device configures the terminal not to perform downlink reception. In other words, outside of these two ambiguous periods, the terminal is configured to perform downlink reception.
[0150] For example, the first time period can be denoted as N1, and the second time period can be denoted as N2. See also... Figure 2 The above, Figure 2 A schematic diagram of a first time period and a second time period provided in this application embodiment can be based on N1 = reported TA - offsetThresholdTAr17 + N RX-TX *T C Determine the first time period before sending the start symbol; based on N2 = reportedTA - offsetThresholdTAr17 + N TX-RX *T C This determines the second time period after the end of the symbol transmission.
[0151] Where reported TA indicates timing advance, offsetThresholdTAr17 represents the preset timing threshold offset value, and N RX-TX T represents the conversion time from downlink reception to uplink transmission at the terminal. C N represents the unit of time. TX-RX This indicates the conversion time when the terminal switches from uplink transmission to downlink reception.
[0152] For example, the value of offsetThresholdTAr17 can be a value in the range of 0.5ms-16ms, and can be set according to actual needs.
[0153] As can be seen, when uplink transmission is semi-statically configured and downlink reception is dynamically scheduled, the network device can determine the first time period before the terminal sends the start symbol based on the uplink transmission timing advance, the preset timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission; and determine the second time period after the terminal finishes sending the symbol based on the uplink transmission timing advance, the timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception. During the first and second time periods, the terminal is configured not to perform downlink reception, so as to constrain the dynamically scheduled downlink reception. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0154] Example 1
[0155] When uplink transmission is configured semi-statically (Semi-static UL) and downlink reception is dynamically scheduled (Dynamic DL), constraints need to be imposed on dynamically scheduled downlink reception to avoid uplink / downlink collisions at the terminal. These constraints include:
[0156] If the higher-layer configuration terminal transmits a Sounding Reference Signal (SRS), PUCCH, or PUSCH on a set of symbols, then it can be based on N1 = reported TA - offsetThresholdTAr17 + N RX-TX *T C Determine the first time interval before sending the start symbol, based on N2 = reported TA - offsetThresholdTAr17 + N TX-RX *T C The system determines the second time period after the end of the symbol transmission, and during the first and second time periods, configures the terminal not to receive Channel State Information-Reference Signal (CSI-RS) or Downlink Control Information (DCI) format of PDSCH, so as to constrain the downlink reception of dynamic scheduling. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0157] In one scenario, uplink transmission is dynamically scheduled, while downlink reception is semi-statically configured. When the target time period is determined based on timing advance, the third time period before the start of reception symbol can be determined based on the timing advance of downlink reception, the preset timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception; and the fourth time period after the end of reception symbol can be determined based on the timing advance of downlink reception, the timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission; wherein, the target time period includes the third and fourth time periods, and the transmission operation is uplink transmission.
[0158] The third time period can be understood as an ambiguous period before the terminal receives the start symbol, and the fourth time period can be understood as an ambiguous period after the terminal finishes receiving the symbol. During these two ambiguous periods, the network device configures the terminal not to perform uplink transmission. In other words, outside of these two ambiguous periods, the terminal is configured to perform uplink transmission.
[0159] For example, the third time period can be denoted as N3, and the fourth time period can be denoted as N4, which can be based on N3 = reported TA - offsetThresholdTAr17 + N.TX-RX *T C Determine the third time period before the terminal receives the start symbol; based on N4 = reported TA - offsetThresholdTAr17 + N RX-TX *T C The fourth time period is determined after the terminal finishes receiving symbols.
[0160] Where, N TX-RX N represents the conversion time from uplink transmission to downlink reception at the terminal. RX-TX This indicates the conversion time when the terminal switches from downlink reception to uplink transmission.
[0161] It can be seen that when uplink transmission is dynamically scheduled and downlink reception is semi-statically configured, when determining the target time period based on timing advance, the third time period before the terminal receives the start symbol can be determined based on the timing advance of downlink reception, the preset timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception. Furthermore, the fourth time period after the terminal receives the end symbol can be determined based on the timing advance of downlink reception, the timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission. During the third and fourth time periods, the terminal is configured not to perform uplink transmission, thus constraining the dynamically scheduled uplink transmission. This effectively solves the problem of uplink / downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0162] Example 2
[0163] When uplink transmission is dynamically scheduled (Dynamic UL scheduling) and downlink reception is semi-static (Semi-static DL configuration), constraints need to be imposed on dynamically scheduled uplink transmission to avoid uplink / downlink collisions at the terminal side. These constraints include:
[0164] If the higher-layer configuration terminal receives PDCCH, PDSCH, CSI-RS, or downlink positioning reference signal (PRS) on a set of symbols, then it can be based on N3 = reported TA - offsetThresholdTAr17 + N. TX-RX *T C Determine the third time period before receiving the start symbol, based on N4 = reported TA - offsetThresholdTAr17 + N RX-TX *T CThe system determines the fourth time period after the end of the received symbol, and during the third and fourth time periods, configures the terminal not to send PUSCH, PUCCH, Physical Random Access Channel (PRACH) or SRS DCI format, in order to constrain the dynamically scheduled uplink transmission. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0165] In another possible scenario, the uplink transmission is configured semi-statically, and the downlink reception is also configured semi-statically.
[0166] For example, in this possible scenario, there are four cases: one is that both uplink transmission and downlink reception are terminal-specific semi-static configurations, i.e., UE-dedicated semi-static UL configuration and UE-dedicated semi-static DL configuration; another is that uplink transmission is terminal-specific semi-static configuration and downlink reception is cell-specific semi-static configuration, i.e., UE-dedicated semi-static UL configuration and Cell-specific semi-static DL configuration; yet another is that uplink transmission is cell-specific semi-static configuration and downlink reception is terminal-specific semi-static configuration, i.e., Cell-specific semi-static UL configuration and UE-dedicated semi-static DL configuration; and a third is that both uplink transmission and downlink reception are cell-specific semi-static configurations, i.e., Cell-specific semi-static UL configuration and Cell-specific semi-static DL configuration.
[0167] For example, in one scenario, both uplink transmission and downlink reception are terminal-specific semi-static configurations. When the target time period is determined in advance based on timing, the target time period can be determined based on the attribute information of uplink transmission, the attribute information of downlink reception, and the timing advance; wherein, the attribute information includes priority, and / or, configuration flexibility.
[0168] For example, in the embodiments of this application, when both uplink transmission and downlink reception are terminal-specific semi-static configurations, the attribute information includes priority. Therefore, the target time period can be determined based on the priority of uplink transmission and downlink reception and the timing advance.
[0169] For example, in embodiments of this application, the priority is configured through at least one of the following:
[0170] Semi-static configuration of Radio Resource Control (RRC) parameters;
[0171] Dynamic configuration of downlink control information;
[0172] Media Access Control Element (MAC CE) Configuration.
[0173] For example, in the embodiments of this application, the configuration flexibility can be time domain period configuration flexibility, time domain position configuration flexibility, etc., which can be set according to actual needs. Here, the embodiments of this application do not impose further restrictions.
[0174] When both uplink transmission and downlink reception are configured at the cell level, or when uplink transmission is configured at the terminal level and downlink reception is configured at the cell level, the attribute information includes configuration flexibility. Therefore, the target time period can be determined based on the configuration flexibility of uplink transmission and downlink reception and the timing advance.
[0175] For example, when the attribute information includes priority, when determining the target time period based on the attribute information of uplink transmission, the attribute information of downlink reception, and the timing advance, the target transmission corresponding to the higher priority can be determined first based on the priority of uplink transmission and the priority of downlink reception; then the target time period can be determined based on the timing advance of the target transmission.
[0176] It is understandable that if the priority of uplink transmission is higher than that of downlink reception, the target transmission is uplink transmission; conversely, if the priority of uplink transmission is lower than that of downlink reception, the target transmission is downlink reception.
[0177] For example, when the target transmission is uplink transmission, when determining the target time period based on the timing advance of the target transmission, the fifth time period before the transmission of the start symbol can be determined based on the timing advance of the uplink transmission, the preset timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission; and the sixth time period after the end of the transmission symbol can be determined based on the timing advance of the uplink transmission, the timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception; wherein the target time period includes the fifth time period and the sixth time period, and the transmission operation is downlink reception.
[0178] The fifth time period can be understood as an ambiguous period before the terminal sends the start symbol, and the sixth time period can be understood as an ambiguous period after the terminal finishes sending the symbol. During these two ambiguous periods, the network device configures the terminal not to perform downlink reception. In other words, outside of these two ambiguous periods, the terminal is configured to perform downlink reception.
[0179] For example, the fifth time period can be denoted as N5, and the sixth time period can be denoted as N6, which can be based on N5 = reported TA - offsetThresholdTAr17 + N. RX-TX *T C Determine the fifth time period before the terminal sends the start symbol; based on N6 = reported TA - offsetThresholdTAr17 + N TX-RX *T C The sixth time period after the terminal finishes sending symbols is determined.
[0180] Where reported TA indicates timing advance, offsetThresholdTAr17 represents the preset timing threshold offset value, and N RX-TX T represents the conversion time from downlink reception to uplink transmission at the terminal. C N represents the unit of time. TX-RX This indicates the conversion time when the terminal switches from uplink transmission to downlink reception.
[0181] It can be seen that when both uplink transmission and downlink reception are terminal-specific semi-static configurations, and the priority of uplink transmission is higher than that of downlink reception, the network device can determine the fifth time period before the terminal sends the start symbol based on the uplink transmission timing advance, the preset timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission; and determine the sixth time period after the terminal finishes sending the symbol based on the uplink transmission timing advance, the timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception. During the fifth and sixth time periods, the terminal is configured not to perform downlink reception, so as to constrain the lower-priority downlink reception. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0182] Example 3
[0183] When both uplink transmission and downlink reception are terminal-specific semi-static configurations (i.e., Semi-static UL configuration and Semi-static DL configuration), if the priority of uplink transmission is higher than that of downlink reception, constraints need to be imposed on the lower-priority downlink reception to avoid uplink-downlink collisions on the terminal side. Specifically, this includes:
[0184] If the higher-level terminal sends its own higher-level parameter configuration on a set of symbols, it can be based on N5 = reported TA - offsetThresholdTAr17 + N RX-TX *T CDetermine the fifth time period before sending the start symbol; and based on N6 = reported TA - offsetThresholdTAr17 + N TX-RX *T C The system determines the sixth time period after the end of the symbol transmission, and during the fifth and sixth time periods, configures the terminal not to receive UE-specific higher layer parameter configurations to constrain downlink reception with lower priority. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0185] For example, when the target transmission is downlink reception, when determining the target time period based on the timing advance of the target transmission, the seventh time period before the start symbol of reception can be determined based on the timing advance of downlink reception, the preset timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception; and the eighth time period after the end of the received symbol can be determined based on the timing advance of downlink reception, the timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission; wherein the target time period includes the seventh time period and the eighth time period, and the transmission operation is uplink transmission.
[0186] The seventh time period can be understood as an ambiguous period before the terminal receives the start symbol, and the eighth time period can be understood as an ambiguous period after the terminal finishes receiving the symbol. During these two ambiguous periods, the network device configures the terminal not to perform uplink transmission. In other words, outside of these two ambiguous periods, the terminal is configured to perform uplink transmission.
[0187] For example, the seventh time period can be denoted as N7, and the eighth time period can be denoted as N8, which can be based on N7 = reported TA - offsetThresholdTAr17 + N. TX-RX *T C Determine the seventh time period; based on N8 = reported TA - offsetThresholdTAr17 + N RX-TX *T C The eighth time slot has been determined.
[0188] Where, N TX-RX N represents the conversion time from uplink transmission to downlink reception at the terminal. RX-TX This indicates the conversion time when the terminal switches from downlink reception to uplink transmission.
[0189] As can be seen, when both uplink transmission and downlink reception are terminal-specific semi-static configurations, and the priority of uplink transmission is lower than that of downlink reception, the network device can determine the seventh time period before the start symbol of reception based on the timing advance of downlink reception, the preset timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception; and determine the eighth time period after the end of the received symbol based on the timing advance of downlink reception, the timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission. During the seventh and eighth time periods, the terminal is configured not to perform uplink transmission, thereby constraining the low-priority uplink transmission. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0190] Example 4
[0191] When both uplink transmission and downlink reception are terminal-specific semi-static configurations (i.e., Semi-static UL configuration and Semi-static DL configuration), if the priority of uplink transmission is lower than that of downlink reception, constraints need to be imposed on uplink transmission to avoid uplink-downlink collisions on the terminal side. These constraints include:
[0192] If the higher-level terminal receives terminal-specific higher-level parameter configuration on a set of symbols, it can be based on N7 = reported TA - offsetThresholdTAr17 + N TX-RX *T C Determine the seventh time period before receiving the start symbol; and based on N8 = reported TA - offsetThresholdTAr17 + N RX-TX *T C The system determines the eighth time period after the end of the received symbol, and during the seventh and eighth time periods, it configures the terminal not to send UE-specific higher layer parameter configurations to constrain uplink transmissions with lower priority. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0193] For example, when the attribute information includes configuration flexibility, when determining the target time period based on the attribute information of uplink transmission, the attribute information of downlink reception, and timing advance, the target transmission corresponding to the lower configuration flexibility can be determined from the uplink transmission and downlink reception based on the configuration flexibility of uplink transmission and downlink reception; and the target time period can be determined based on the timing advance of the target transmission.
[0194] Generally, terminal-specific semi-static configurations offer greater flexibility than cell-level semi-static configurations.
[0195] It is understood that, in the embodiments of this application, if the uplink transmission is a terminal-specific semi-static configuration and the downlink reception is a cell-level semi-static configuration, then the target transmission is the uplink transmission; if the uplink transmission is a cell-level semi-static configuration and the downlink reception is a terminal-specific semi-static configuration, then the target transmission can be either downlink reception or uplink transmission, which can be determined by the terminal itself; if both the uplink transmission and downlink reception are cell-level semi-static configurations, then the target transmission can be downlink reception.
[0196] For example, in another scenario, the uplink transmission is configured as a terminal-specific semi-static configuration, and the downlink reception is configured as a cell-level semi-static configuration. Given that the terminal-specific semi-static configuration offers greater flexibility than the cell-level semi-static configuration, and the target transmission is downlink reception, the target time period can be determined based on the timing advance of the downlink reception. The specific implementation is similar to the above-described implementation of determining the target time period based on the timing advance of the target transmission when the target transmission is downlink reception; please refer to the relevant descriptions above. Therefore, this application's embodiments will not repeat the details here.
[0197] Example 5
[0198] When uplink transmission is configured with a terminal-specific semi-static setup and downlink reception is configured with a cell-level semi-static setup (i.e., UE-dedicated semi-static UL configuration and Cell-specific semi-static DL configuration), given that the terminal-dedicated semi-static configuration offers greater flexibility than the cell-level semi-static configuration, constraints are needed on the uplink transmission to avoid uplink / downlink collisions at the terminal side. These constraints include:
[0199] If the higher-level configuration terminal receives the Common Search Space (CSS) set configuration on a set of symbols (Type-0 / 0A / 1 / 2-PDCCH), then it can be based on N7 = reported TA-offsetThresholdTAr17 + N. TX-RX *T C Determine the seventh time period before receiving the start symbol; and based on N8 = reported TA - offsetThresholdTAr17 + N RX-TX *T C The eighth time period after the end of the received symbol is determined, and during the seventh and eighth time periods, the terminal is configured not to send the Type-0 / 0A / 1 / 2-PDCCH CSS set configuration to constrain the uplink transmission. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0200] For example, in another scenario, uplink transmission is configured as a cell-specific semi-static UL, while downlink reception is configured as a terminal-specific semi-static UL. Given that cell-specific semi-static UL configurations only contain valid Random Access Channel Occasions (ROs), the terminal can choose to receive uplink data (i.e., designate uplink transmission as the target transmission) or downlink data (i.e., designate downlink reception as the target transmission), referencing existing Valid RO and Specific Semi-static UL configurations or Valid RO and Dynamic UL configurations. Both are acceptable to network devices. Therefore, the processing rules for Valid RO and Specific Semi-static UL configurations or Valid RO and Dynamic UL configurations in existing terrestrial systems can be continued to address the uplink / downlink collisions at the terminal side caused by unreasonable base station transmission configurations.
[0201] For example, in another scenario, both uplink transmission and downlink reception are configured at the cell level as semi-static. A typical example in this case is that the Cell-specific Semi-static DL signal is a Synchronization Signal Block (SSB) and a Type 0 / 0A / 1 / 2-CSS PDCCH. Therefore, in this embodiment, the processing rules for the SSB and valid RO can be referenced from existing SSB and Specific Semi-static UL configurations, or SSB and Dynamic UL configurations; the processing rules for the Type 0 / 0A / 1 / 2-CSS PDCCH and valid RO can be referenced from existing Valid RO and Specific Semi-static UL configurations, or Valid RO and Dynamic UL configurations. These will not be elaborated further in this embodiment, thereby resolving the problem of uplink / downlink collisions at the terminal side caused by unreasonable base station transmission configurations.
[0202] For example, in the case of SSB and Specific Semi-static UL configuration, or SSB and Dynamic UL configuration, the network device can determine the time period before the start symbol of the received SSB signal and the time period after the end of the received SSB signal symbol. The specific implementation is similar to the specific implementation of determining the seventh time period before the start symbol and the eighth time period after the end of the received symbol, as described above. Therefore, this embodiment will not repeat the details here. After determining these two time periods, the terminal can be configured not to perform uplink transmission during these two time periods to constrain uplink transmission, thereby effectively solving the problem of uplink / downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0203] Example 6
[0204] In the case of SSB and Specific Semi-static UL configuration, or SSB and Dynamic UL configuration, if the terminal has a synchronization signal (SS) or a physical broadcast channel block (PBCH) on a set of symbols of the activated DL bandwidth part (BWP) via System Information Block (SIB) 1, ServingCellConfigCommon's ssb-PositionsInBurst, or NonCellDefiningSSB, then it can be based on N7 = reported TA-offsetThresholdTAr17 + N. TX-RX *T C Determine the seventh time period before the indicator start symbol; and based on N8 = reported TA - offsetThresholdTAr17 + N RX-TX *T C The system determines the eighth time period after the end of the indicator symbol, and configures the terminal not to detect the DCI format of the scheduling PUSCH, PUCCH, or SRS transmission during the seventh and eighth time periods to constrain the uplink transmission. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0205] If the terminal activates the DL BWP via SIB1, ServingCellConfigCommon's ssb-PositionsInBurst, or NonCellDefiningSSB, and an SS or PBCH exists on a set of symbols, then it can also be based on N7 = reported TA-offsetThresholdTAr17+N TX-RX *T C Determine the seventh time period before the indicator start symbol; and based on N8 = reported TA - offsetThresholdTAr17 + N RX-TX *T C The system determines the eighth time period after the end of the indicator symbol, and during the seventh and eighth time periods, configures the terminal not to send PUSCH, PUCCH, or SRS configured by higher layers, in order to constrain uplink transmission. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0206] In another possible scenario, uplink transmission is dynamically scheduled, and downlink reception is also dynamically scheduled, namely Dynamic UL scheduling and Dynamic DL scheduling.
[0207] For example, when both uplink transmission and downlink reception are dynamically scheduled, to determine the target time period based on advance timing, the target transmission corresponding to the higher priority can be determined from the uplink transmission and downlink reception based on their priorities; the target time period can then be determined based on the advance timing of the target transmission.
[0208] For example, in embodiments of this application, the priority is configured through at least one of the following:
[0209] Semi-static configuration of Radio Resource Control (RRC) parameters;
[0210] Dynamic configuration of downlink control information;
[0211] Media Access Control Element (MAC CE) Configuration.
[0212] It is understandable that if the priority of uplink transmission is higher than that of downlink reception, the target transmission is uplink transmission; conversely, if the priority of uplink transmission is lower than that of downlink reception, the target transmission is downlink reception.
[0213] For example, when the target transmission is uplink transmission, when determining the target time period based on the timing advance of the target transmission, the fifth time period before the transmission of the start symbol can be determined based on the timing advance of the uplink transmission, the preset timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission; and the sixth time period after the end of the transmission symbol can be determined based on the timing advance of the uplink transmission, the timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception; wherein the target time period includes the fifth time period and the sixth time period, and the transmission operation is downlink reception.
[0214] The fifth time period can be understood as an ambiguous period before the terminal sends the start symbol, and the sixth time period can be understood as an ambiguous period after the terminal finishes sending the symbol. During these two ambiguous periods, the network device configures the terminal not to perform downlink reception. In other words, outside of these two ambiguous periods, the terminal is configured to perform downlink reception.
[0215] For example, the fifth time period can be denoted as N5, and the sixth time period can be denoted as N6, which can be based on N5 = reported TA - offsetThresholdTAr17 + N. RX-TX *T C Determine the fifth time period before the terminal sends the start symbol; based on N6 = reported TA - offsetThresholdTAr17 + N TX-RX *T C The sixth time period after the terminal finishes sending symbols is determined.
[0216] Where reported TA indicates timing advance, offsetThresholdTAr17 represents the preset timing threshold offset value, and N RX-TX T represents the conversion time from downlink reception to uplink transmission at the terminal. C N represents the unit of time. TX-RX This indicates the conversion time when the terminal switches from uplink transmission to downlink reception.
[0217] It can be seen that when both uplink transmission and downlink reception are terminal-specific semi-static configurations, and the priority of uplink transmission is higher than that of downlink reception, the network device can determine the fifth time period before the terminal sends the start symbol based on the uplink transmission timing advance, the preset timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission; and determine the sixth time period after the terminal finishes sending the symbol based on the uplink transmission timing advance, the timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception. During the fifth and sixth time periods, the terminal is configured not to perform downlink reception, so as to constrain the lower-priority downlink reception. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0218] Example 7
[0219] When both uplink transmission and downlink reception are dynamically scheduled, if the priority of uplink transmission is higher than that of downlink reception, constraints need to be imposed on the lower-priority downlink reception to avoid uplink-downlink collisions at the terminal. Specifically, this includes:
[0220] If the terminal detects the transmitted DCI format on a set of symbols, it can be based on N5 = reported TA - offsetThresholdTAr17 + N RX-TX *T C Determine the fifth time period before sending the start symbol; and based on N6 = reported TA - offsetThresholdTAr17 + N TX-RX *T C The system determines the sixth time period after the end of the symbol transmission, and configures the terminal not to receive DCI format during the fifth and sixth time periods to constrain downlink reception with lower priority. This effectively solves the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0221] For example, when the target transmission is downlink reception, when determining the target time period based on the timing advance of the target transmission, the seventh time period before the start symbol of reception can be determined based on the timing advance of downlink reception, the preset timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception; and the eighth time period after the end of the received symbol can be determined based on the timing advance of downlink reception, the timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission; wherein the target time period includes the seventh time period and the eighth time period, and the transmission operation is uplink transmission.
[0222] The seventh time period can be understood as an ambiguous period before the terminal receives the start symbol, and the eighth time period can be understood as an ambiguous period after the terminal finishes receiving the symbol. During these two ambiguous periods, the network device configures the terminal not to perform uplink transmission. In other words, outside of these two ambiguous periods, the terminal is configured to perform uplink transmission.
[0223] For example, the seventh time period can be denoted as N7, and the eighth time period can be denoted as N8, which can be based on N7 = reported TA - offsetThresholdTAr17 + N. TX-RX *T C Determine the seventh time period before receiving the start symbol; based on N8 = reportedTA - offsetThresholdTAr17 + N RX-TX *T C The eighth time slot is determined after the end of the received symbol.
[0224] Where, N TX-RX N represents the conversion time from uplink transmission to downlink reception at the terminal. RX-TX This indicates the conversion time when the terminal switches from downlink reception to uplink transmission.
[0225] It can be seen that when both uplink transmission and downlink reception are terminal-specific semi-static configurations, and the priority of uplink transmission is lower than that of downlink reception, the network device can determine the seventh time period before the start symbol of reception based on the timing advance of downlink reception, the preset timing threshold offset value, and the transition time of the terminal from uplink transmission to downlink reception; and determine the eighth time period after the end of reception symbol based on the timing advance of downlink reception, the timing threshold offset value, and the transition time of the terminal from downlink reception to uplink transmission. During the seventh and eighth time periods, the terminal is configured not to perform uplink transmission, so as to constrain the low-priority uplink transmission. This can effectively solve the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0226] Example 8
[0227] When both uplink transmission and downlink reception are terminal-specific semi-static configurations (i.e., Semi-static UL and Semi-static DL), if the priority of uplink transmission is lower than that of downlink reception, constraints need to be imposed on the lower-priority uplink transmission to avoid uplink-downlink collisions on the terminal side. Specifically, this includes:
[0228] If the terminal detects the received DCI format on a set of symbols, it can be based on N7 = reported TA - offsetThresholdTAr17 + N TX-RX *T CDetermine the seventh time period before receiving the start symbol; and based on N8 = reported TA - offsetThresholdTAr17 + N RX-TX *T C The system determines the eighth time period after the end of the received symbol, and configures the terminal not to send DCI format during the seventh and eighth time periods to constrain uplink transmissions with lower priority. This effectively solves the problem of uplink and downlink collisions on the terminal side caused by unreasonable transmission configuration of the base station.
[0229] It is understood that in the embodiments of this application, when determining the time period before sending the start symbol or the time period before receiving the start symbol, if the calculated time period value is greater than 0, the time period value is determined to be the calculated time period value; if the calculated time period value is less than 0, the time period value is determined to be 0. The specific settings can be made according to actual needs.
