It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.
[0039] To facilitate a better understanding of the embodiments of this application, the random access process related to this application is described.
[0040] The random access process can be a contention-based random access process or a contention-free random access process. The random access process can be a four-step random access process (also known as a Type-1 random access process) or a two-step random access process (also known as a Type-2 random access process).
[0041] In the four-step random access procedure (4-step RACH), the UE first sends Message 1 (MSG.1) to the network, which contains a preamble; after the network detects the preamble, it will send Message 2 (MSG.2) or a Random Access Response (RAR) message, which contains the number of the preamble detected by the network and the uplink radio resources allocated to the UE to send Message 3 (MSG.3); after the UE receives MSG.2 and confirms that at least one of the preamble numbers carried in MSG.2 is the same as the preamble number it sent, it sends MSG.3 containing contention resolution information according to the resources indicated by the RAR; after the network receives MSG.3, it will send Message 4 (MSG.4) containing contention resolution information; after the UE receives MSG.4 and confirms that the resolution information is the same as what it sent in MSG.3, the four-step random access is completed.
[0042] The network includes uplink grant (UL grant) information in the RAR to indicate the scheduling information of the Physical Uplink Shared Channel (PUSCH) for MSG.3, and includes information such as Random Access Preamble ID (RAPID), Temporary Cell Radio Network Temporary Identity (TC-RNTI), and Timing Advance (TA). If the network does not receive the MSG.3 PUSCH, it can schedule the retransmission of the MSG.3 PUSCH in the Physical Downlink Control Channel (PDCCH) scrambled with the TC-RNTI.
[0043] For the competitive random access process, different UEs randomly select preambles for transmission. In this way, different UEs may select the same preamble to send on the same time-frequency radio resource (RACH opportunity (RO) resource). This situation can be understood as a preamble collision of UEs. In this case, different UEs will receive the same RAR. Then, different UEs will perform the transmission of MSG.3 PUSCH according to the scheduling information in the RAR UL grant. The network decodes the PUSCH (including the contention resolution information) sent by the UE on the MSG.3 PUSCH scheduling resource. Therefore, the network will include the contention resolution information received in MSG.3 in MSG.4. If the contention resolution information in the MSG.4 received by the UE matches the contention resolution information sent by the UE in MSG.3 PUSCH, the UE considers the contention resolution successful. If not, the contention resolution is considered unsuccessful.
[0044] If the contention resolution is unsuccessful, the UE reselects the RACH resource, sends a Physical Random Access Channel (PRACH), and makes the next random access attempt.
[0045] In the two-step random access process (2-step RACH), the first step is for the UE to send MsgA to the network side. After receiving MsgA, the network side sends MsgB to the UE. If the UE does not receive MsgB within a certain time, the UE will increment the counter that counts the number of MsgA transmissions and re-send MsgA. If the counter that counts the number of MsgA transmissions reaches a certain threshold, the UE will switch from the 2-step random access process to the 4-step random access process.
[0046] MsgA includes a MsgA preamble part and a MsgA PUSCH part. The preamble part is sent on the RO for 2-step RACH, and the PUSCH part is sent on the MsgA PUSCH resource associated with the sent MsgA preamble and RO. The MsgA PUSCH resource is a set of PUSCH resources configured for each PRACH slot, including time-frequency resources and Demodulation Reference Signal (DMRS) resources, and is associated with the PRACH resources within the PRACH slot.
[0047] To facilitate a better understanding of the embodiments of the present application, the enhanced duplex mode related to the present application is described.
[0048] In the 5G mobile communication system, enhanced technologies have been developed for full duplex to meet diverse scenario and service requirements. The main scenarios of 5G include Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communication (URLLC), and massive machine type of communication (mMTC). These scenarios pose requirements on the system such as high reliability, low latency, large bandwidth, and wide coverage.
[0049] In NR, configuring the full duplex mode can significantly improve the latency and coverage performance of a Time Division Duplex (TDD) system. Specifically, for example, configuring the subband non-overlapping full duplex mode, where the non-overlapping subband full duplex mode means that within a carrier bandwidth, simultaneous uplink and downlink transmission or reception is allowed on non-overlapping subband resources. Since there is no overlap between the uplink subband and the downlink subband, self-interference is relatively small, which can reduce transmission latency and enhance coverage.
[0050] For a downlink slot (DL slot), the network configures a downlink (DL) Bandwidth Part (BWP) for the UE (configured by the tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), such as Figure 2 Slot 1 in the figure; for an uplink (UL) slot, the network configures a UL BWP for the UE (configured by the tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), such as Figure 3 Slot 4 in the figure.
[0051] For a downlink slot (DL slot) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), in the full duplex scenario, as Figure 2 shown, there are the following cases:
[0052] Case 1: Configure a DL BWP, such as slot 1;
[0053] Case 2: Configure a DL BWP and an uplink sub-band (UL sub band), such as slot 2.
[0054] For an uplink slot (UL slot) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), in a full duplex scenario, as Figure 3 shown, there are the following examples (cases):
[0055] Case 3: Configure a UL BWP, such as slot 4;
[0056] Case 4: Configure a UL BWP and a downlink sub-band (DL sub band), such as slot 5.
[0057] For sub-band full duplex (SBFD) operation, an SBFD sub-band consists of 1 resource block (RB) or a continuous set of RBs with the same transmission direction.
[0058] The time unit (such as a slot or a symbol) used by the gNB for SBFD operation can be called an SBFD time unit (such as a slot or a symbol).
[0059] An exemplary duplex mode is as follows: The network side is full duplex. At the same moment, uplink transmission and downlink transmission can be carried out simultaneously at different frequency domain positions. To avoid interference between the uplink and the downlink, a certain guard band can be left between the frequency domain positions (corresponding to duplex sub-bands) for different transmission directions; The terminal side is half duplex, that is, consistent with TDD. At the same moment, only uplink transmission or downlink transmission can be performed, and the two cannot be carried out simultaneously. It can be understood that in this duplex mode, the uplink transmission and downlink transmission of the network side at the same moment can only be for different terminals.
[0060] Another exemplary duplex mode is as follows: Both the terminal side and the network side are full duplex, as Figure 4 shown, that is, both the terminal side and the network side operate in the duplex mode. Specifically, for the terminal side and the network side, at the same moment, uplink transmission (uplink, UL) and downlink transmission (downlink, DL) can be carried out simultaneously at different frequency domain positions.
[0061] For full duplex on the UE side, a relatively large guard band (GB) (larger than the GB for base station frequency division (FD)) may be required to suppress self-interference, such as Figure 5 as shown
[0062] For a communication device, simultaneous UL reception and DL transmission can cause self-interference. To ensure transmission in the interfered direction, the communication device needs to have the ability to cancel self-interference. For example, a guard band is reserved between the receiving band and the transmitting band, but this will reduce the throughput of the UE.
[0063] To facilitate the understanding of the embodiments of the present application, the uplink sounding reference signal (SRS) resources related to the present application are described.
[0064] In NR, uplink beam training is supported through SRS. However, in the initial access phase, since the terminal does not send SRS, there is no uplink beam management. The uplink beam used by the terminal when sending the preamble and Msg3, or MsgA, depends on the implementation of the terminal. However, in the 4-step RACH, there is a requirement for the consistency of the uplink beam used by the terminal to send Msg3 and the uplink beam of the physical uplink control channel (PUCCH) carrying the hybrid automatic repeat request acknowledgement (HARQ-ACK) of Msg4, that is, the terminal needs to ensure that the uplink beam used to send Msg3 is the same as the uplink beam used by the PUCCH to send the HARQ-ACK carrying Msg4. Similarly, for the 2-step RACH, the terminal needs to ensure that the uplink beam used to send MsgA is the same as the uplink beam used by the PUCCH to send the HARQ-ACK carrying MsgB. In the radio resource control (RRC) connected state, the uplink beam training results based on SRS can be used for subsequent uplink transmissions.
[0065] When introducing the duplex mode, how to configure SRS is an urgent problem to be solved.
[0066] To facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail through specific embodiments below. The above related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least some of the following contents.
[0067] Figure 6 is a schematic flowchart of a method 200 for configuring SRS resources according to an embodiment of the present application. As Figure 6 shown, the method 200 for configuring SRS resources may include at least some of the following:
[0068] S210, the network side device sends uplink configuration information to the terminal; wherein, the uplink configuration information is used to configure at least one of the following: SRS resources, SRS resource sets; wherein, the uplink configuration information is associated with the duplex configuration;
[0069] Correspondingly, the terminal receives the uplink configuration information from the network side device;
[0070] S220, the terminal sends SRS according to the uplink configuration information.
[0071] Correspondingly, the network side device receives SRS according to the uplink configuration information.
[0072] In the embodiments of the present application, the terminal may support full duplex or half duplex, and the network side device may support full duplex or half duplex. For example, the network side device supports full duplex, and the terminal supports full duplex or half duplex. Another example is that the network side device supports half duplex, and the terminal supports half duplex.
[0073] The duplex mode described in the embodiments of the present application may be, for example, an enhanced duplex mode, or enhanced duplex, cross duplex (XDD), enhanced full duplex, enhanced full duplex mode. The embodiments of the present application do not limit this.
[0074] The duplex configuration described in the embodiments of the present application may be, for example, an enhanced duplex configuration, or cross duplex (XDD) configuration, enhanced full duplex configuration. The embodiments of the present application do not limit this.
[0075] In a specific embodiment, the uplink configuration information is associated with an enhanced duplex configuration. For example, the SRS resources configured by the uplink configuration information can be used for SRS transmission in the enhanced duplex mode.
[0076] In some embodiments of the present application, the terminal may determine the duplex configuration according to the uplink configuration information, so that there is no need to introduce additional duplex configuration signaling overhead.
[0077] Therefore, in the embodiments of the present application, the terminal can determine the duplex configuration based on the configuration of SRS resources or SRS resource sets, without a separate signaling for duplex configuration. The duplex configuration is more flexible, and the duplex configuration is associated with SRS resources, enabling SRS transmission in the duplex mode, improving the utilization rate of system resources, and also reducing the transmission delay of SRS.
[0078] The duplex configuration described in the embodiments of the present application may refer to: configuring an uplink sub-band in a downlink time unit, or configuring a downlink sub-band in an uplink time unit. Thus, duplex transmission of downlink and uplink can be achieved in a downlink time unit, or duplex transmission of downlink and uplink can be achieved in an uplink time unit.
[0079] Therefore, compared with only being able to configure a downlink sub-band in a downlink time unit, or only being able to configure an uplink sub-band in an uplink time unit, when the uplink configuration information is associated with the duplex configuration, the network-side device can configure SRS resources on the uplink sub-band configured in the downlink time unit, or can also configure SRS resources in the uplink time unit. Therefore, there are more choices for the SRS resource location, which is beneficial to reducing the transmission delay of SRS. For example, when the network-side device configures multiple SRS resources, the terminal can select the earliest SRS resource to send SRS, thereby being able to reduce the transmission delay of SRS.
[0080] The reference signals described in the embodiments of the present application include but are not limited to at least one of the following:
[0081] Synchronization Signal Block (SSB), Channel State Information Reference Signal (CSI-RS), message A (MsgA) in two-step random access, MsgA PUSCH, Physical Random Access Channel (PRACH), Tracking reference signal (TRS) (TRS is a reference signal for time-frequency resource estimation), Sounding Reference Signal (SRS).
[0082] The association relationship between the reference signals and the SRS resources described in the embodiments of the present application includes but is not limited to at least one of the following:
[0083] The association relationship between SSB and SRS resources, the association relationship between CSI-RS and SRS resources, the association relationship between PRACH resources and SRS resources, the association relationship between MsgA resources and SRS resources, the association relationship between MsgA PUSCH resources and SRS resources, the association relationship between TRS resources and SRS resources, the association relationship between Configured Grant Physical Uplink Shared Channel (CGPUSCH) resources and SRS resources.
[0084] The association relationship described in the embodiments of the present application can also be referred to as a mapping relationship. For example, it can be an equality relationship in transmission characteristics (such as beam) between two signals or channel resources.
[0085] For example, the association relationship between a PRACH resource and an SRS resource can mean that the beam used for the SRS transmitted on the SRS resource is the same as the beam used for the PRACH transmitted on the PRACH resource.
[0086] Specifically, for example, when using SRS for uplink beam training, the beam of the SRS selected by the terminal can be used as the beam for subsequent transmission of the PRACH. Or, the beam used for transmitting the PRACH can also be used as the beam for transmitting the SRS.
[0087] Again, for example, the association relationship between a MsgA resource and an SRS resource can mean that the beam used for the SRS transmitted on the SRS resource is the same as the beam used for the MsgA transmitted on the MsgA resource.
[0088] Specifically, for example, when using SRS for uplink beam training, the beam of the SRS selected by the terminal can be used as the beam for subsequent transmission of the MsgA. Or, the beam used for transmitting the MsgA can also be used as the beam for transmitting the SRS.
[0089] Furthermore, for example, the association relationship between a MsgA PUSCH resource and an SRS resource can mean that the beam used for the SRS transmitted on the SRS resource is the same as the beam used for the MsgA PUSCH transmitted on the MsgA PUSCH resource.
[0090] Specifically, for example, when using SRS for uplink beam training, the beam of the SRS selected by the terminal can be used as the beam for subsequent transmission of the MsgA PUSCH. Or, the beam used for transmitting the MsgA PUSCH can also be used as the beam for transmitting the SRS.
[0091] Introducing SRS transmission in the Idle or Inactive state can be used for the terminal's uplink beam management or uplink capacity enhancement.
[0092] By introducing the association between SSB / CSI-RS and SRS resources, the terminal can perform uplink beam training before cell access, determine a more suitable PRACH transmission beam, and improve the reliability of PRACH reception.
[0093] By introducing the association between PRACH resources / MsgA resources / MsgA PUSCH resources and multiple SRS resources, different terminals can use the beams associated with different SRSs to transmit the same PRACH, improving the capacity of the PRACH.
[0094] By introducing the association of multiple PRACH resources / MsgA resources / MsgA PUSCH resources to SRS resources, it is possible to support the repetition of multiple PRACH / MsgA / MsgA PUSCH resources using the same SRS resource, thereby improving the reliability of PRACH / MsgA / MsgA PUSCH resource transmission.
[0095] The SSB described in the embodiments of this application can also be called a resource block, which includes at least one of a synchronization signal, a broadcast signal, a broadcast channel (PBCH), and other system messages.
[0096] In the embodiments of this application, the repeated transmission of SRS can be the repeated transmission during the initial transmission of SRS, or the repeated transmission during the retransmission of SRS.
[0097] In the embodiments of this application, the SRS resource can be the SRS time-frequency resource and / or the SRS sequence. The name of this SRS is only an example and can also be replaced by other names, such as the uplink signal resource for the terminal in the idle state (Idle) or the inactive state (Inactive).
[0098] It should be understood that the embodiments of this application do not limit the use of SRS. For example, it can be used for beam training, or for terminal positioning, etc. For example, when the terminal is in the inactive state (Inactive), the network side device can configure SRS resources for the terminal to send SRS for terminal positioning in the inactive state.
[0099] In some embodiments, the uplink configuration information can be configured in the idle state (Idle) or the inactive state (Inactive), or the uplink configuration information can also be dynamically configured in the random access phase.
[0100] In other words, the embodiments of this application can obtain the SRS resource configuration in the duplex mode in the idle state (Idle) or the inactive state (Inactive) or the random access phase, making the configuration method of SRS resources more flexible, and the duplex configuration can also be determined according to the uplink configuration information without introducing additional duplex configuration signaling overhead.
[0101] In some embodiments, the uplink configuration information can also be configured in the connected state. In other words, the embodiments of this application can obtain the SRS resource configuration in the duplex mode in the connected state, making the configuration method of SRS resources more flexible, and the duplex configuration can also be determined according to the uplink configuration information without introducing additional duplex configuration signaling overhead.
[0102] In some embodiments, the terminal determining the duplex configuration according to the uplink configuration information may specifically include:
[0103] The terminal determines an uplink subband on the at least one downlink time unit according to the SRS resources on the at least one downlink time unit.
[0104] Wherein, the SRS resources on the at least one downlink time unit include at least one of the following: some or all of the SRS resources configured by the uplink configuration information, and some or all of the SRS resources in the SRS resource set configured by the uplink configuration information.
[0105] Therefore, through this embodiment, it is clear that an uplink subband on the at least one downlink time unit can be determined based on the SRS resources on the at least one downlink time unit. After determining the uplink subband on the at least one downlink time unit, the duplex configuration on the at least one downlink time unit can be obtained.
[0106] In some embodiments, the downlink time unit may include but is not limited to at least one of the following: Orthogonal Frequency-Division Multiplexing (OFDM) symbol, time slot, subframe, frame, microsecond, millisecond, second, minute, hour, day, week, month.
[0107] Specifically, for example, taking the downlink time unit as a downlink slot (DL slot), the terminal can determine the uplink subband on the downlink slot through the SRS resources on the downlink slot.
[0108] In some embodiments, the terminal determines some or all of the physical resource blocks (PRBs) occupied by the SRS resources on the at least one downlink time unit as the uplink subband, where the SRS resources on the at least one downlink time unit are valid.
[0109] Exemplarily, the SRS resources on the at least one downlink time unit being valid can be understood as: there is a mapping relationship between the reference signal and the SRS resources on the at least one downlink time unit, or in other words, the mapping relationship from the reference signal to the SRS resources on the at least one downlink time unit is satisfied.
[0110] It should be noted that the SRS resources need to be mapped (or associated) to the reference signal. The terminal selects a reference signal that meets a certain RSRP quality according to the measurement of the reference signal, and determines the SRS resources for uplink data transmission according to the selected reference signal. Taking the reference signal as the SSB as an example, the SRS resources need to be mapped to the SSB. The terminal selects an SSB that meets a certain RSRP quality according to the measurement of the SSB, and determines the SRS resources according to the selected SSB.
[0111] Specifically, for example, taking the following downlink time unit as a downlink slot (DL slot), on all downlink slots where SRS resources appear, the PRBs occupied by the SRS resources are considered to be configured as uplink subbands, and the SRS resources are considered valid.
[0112] As Figure 7 shown, on downlink slot n, the partial PRBs (PRBs excluding the guard interval) occupied by the SRS resources are considered to be configured as uplink subbands, and the SRS resources are considered valid.
[0113] In some embodiments, on each downlink time unit in at least one downlink time unit, the partial or full bandwidth occupied by at least one SRS resource adjacent to the uplink subband is a guard interval. Specifically, the setting of the guard interval can suppress the self-interference generated by simultaneous reception and transmission.
[0114] Specifically, for example, taking the following downlink time unit as a downlink slot (DL slot), as Figure 7 shown, on downlink slot n, the full bandwidth (or rather, all PRBs) occupied by one SRS resource adjacent to the uplink subband is a guard interval.
[0115] Specifically, for example, taking the following downlink time unit as a downlink slot (DL slot), as Figure 8 shown, on downlink slot n, the partial bandwidth occupied by one SRS resource adjacent to the uplink subband is a guard interval.
[0116] In some embodiments, the terminal determines the duplex configuration according to the uplink configuration information, which may specifically include:
[0117] The terminal determines the downlink subbands on at least one uplink time unit according to the SRS resources on the at least one uplink time unit;
[0118] Among them, the SRS resources on the at least one uplink time unit include at least one of the following:
[0119] Part or all of the SRS resources configured by the uplink configuration information;
[0120] Part or all of the SRS resources in the SRS resource set configured by the uplink configuration information.
[0121] Therefore, through this embodiment, it is clear that the downlink subbands on at least one uplink time unit can be determined based on the SRS resources on the at least one uplink time unit. After determining the downlink subbands on the at least one uplink time unit, the duplex configuration on the at least one uplink time unit can be known.
[0122] In some embodiments, the uplink time unit may include, but is not limited to, at least one of the following: OFDM symbol, time slot, subframe, frame, microsecond, millisecond, second, minute, hour, day, week, month.
[0123] In some embodiments, the terminal determines that a part or all of the PRBs except for the PRBs occupied by the SRS resources on the at least one uplink time unit are downlink subbands, where the SRS resources on the at least one uplink time unit are valid.
[0124] In some embodiments, on each of the at least one uplink time unit, a part or all of the bandwidth occupied by at least one SRS resource adjacent to the downlink subband is used as a guard interval. Specifically, the setting of the guard interval can suppress the self-interference generated by simultaneous reception and transmission.
[0125] Exemplarily, the SRS resources on at least one uplink time unit being valid can be understood as:
[0126] There is a mapping relationship between the reference signal and the SRS resources on the at least one time unit, or rather, it satisfies the mapping relationship between the reference signal and the SRS resources on at least one uplink time unit.
[0127] In some embodiments, the at least one SRS resource satisfies at least one of the following:
[0128] It satisfies the mapping relationship between the reference signal and the SRS resource (or rather, the reference signal and the SRS resource have a mapping relationship), and is not used to transmit SRS;
[0129] It satisfies the mapping relationship between the reference signal and the SRS resource (or rather, the reference signal and the SRS resource have a mapping relationship), and is not used to transmit SRS under the condition of satisfying a preset condition;
[0130] It does not satisfy the mapping relationship between the reference signal and the SRS resource (or rather, the reference signal and the SRS resource do not have a mapping relationship).
[0131] Specifically, through this embodiment, the conditions satisfied by the at least one SRS resource where the guard interval is located are clarified, which is beneficial to better utilization of SRS resources.
[0132] In some embodiments, for at least one SRS resource whose part or all of the bandwidth is used as a guard interval, if it satisfies the mapping relationship between the reference signal and the SRS resource, it can be considered that the SRS resource is valid, or if the SRS resource does not satisfy the mapping relationship between the reference signal and the SRS resource, it can be considered that the SRS resource is not valid.
[0133] In some embodiments, for at least one SRS resource where part or all of the bandwidth is used as a guard interval, SRS may not be transmitted in the same way, or alternatively, it may not be used for SRS transmission when preset conditions are met. The preset conditions can be understood as conditions where SRS transmission does not cause interference or causes relatively little interference to the transmission of downlink signals or downlink channels.
[0134] In some embodiments, the preset conditions include but are not limited to at least one of the following:
[0135] The time domain interval between the SRS resource and the reference signal is less than or not greater than a first time threshold;
[0136] The frequency domain interval between the SRS resource and the reference signal is less than or not greater than a first frequency threshold;
[0137] There is transmission of a reference signal on the remaining bandwidth outside the uplink subband;
[0138] There is transmission of a downlink common channel or a downlink common signal on the remaining bandwidth outside the uplink subband;
[0139] There is reception of a reference signal on the remaining bandwidth outside the uplink subband;
[0140] There is reception of a downlink common channel or a downlink common signal on the remaining bandwidth outside the uplink subband.
[0141] Therefore, when the preset conditions are met, the at least one SRS resource is not used for SRS transmission, thereby avoiding interference from SRS transmission to the transmission of reference signals or downlink common channels or downlink common signals.
[0142] Exemplarily, taking the downlink time unit as a downlink slot (DL slot) as an example, as Figure 7 or Figure 8 shown, the remaining bandwidth outside the uplink subband may include the bandwidth occupied by the guard interval and the downlink subband.
[0143] Optionally, the first time threshold can be agreed upon by the protocol or configured by the network side device.
[0144] Optionally, the first frequency threshold can be agreed upon by the protocol or configured by the network side device.
[0145] In some embodiments, the preset conditions are preconfigured by the network side device, or the preset conditions are agreed upon by the protocol.
[0146] In some embodiments, the uplink configuration information is also used to configure the guard interval on the at least one downlink time unit or the at least one uplink time unit. Specifically, the setting of the guard interval can suppress the self-interference generated by simultaneous reception and transmission.
[0147] In the embodiments of the present application, in the enhanced duplex mode, SRS resources may be allowed on the uplink subbands of the additionally configured downlink time units, so new SRS resource types may occur.
[0148] In some embodiments, the SRS resources configured by the uplink configuration information include at least one of the following types:
[0149] SRS resources existing on the uplink time unit;
[0150] SRS resources existing on the time unit with flexible symbols;
[0151] SRS resources existing on the uplink subbands of the downlink time unit;
[0152] SRS resources existing on the uplink subbands of the downlink time unit, and there are no reference signal resources on the downlink time unit;
[0153] SRS resources existing on the uplink subbands of the downlink time unit, and there are reference signal resources on the downlink time unit;
[0154] SRS resources not on the uplink subbands of the downlink time unit.
[0155] By configuring at least one of the above types of SRS resources, the terminal can use the at least one type of SRS resource for SRS transmission in the duplex mode, which can reduce the transmission delay of SRS. And performing SRS transmission on the uplink subbands of the downlink time unit can improve the utilization rate of system resources.
[0156] As a specific example, the SRS resource types may include SRS resources on the uplink subbands and SRS resources not on the uplink subbands (such as downlink subbands or unconfigured subbands).
[0157] In some embodiments, the uplink time unit may include at least one of the following: OFDM symbol, time slot, subframe, frame, microsecond, millisecond, second, minute, hour, day, week, month.
[0158] In some embodiments, the set of SRS resources configured by the uplink configuration information satisfies at least one of the following:
[0159] Includes different types of SRS resources;
[0160] Includes the same type of SRS resources;
[0161] Mapped to the same reference signal resource, such as the same SSB index, or the same CSI-RS index, or the same preamble, or the same Msg A resource index, or the same Msg A PUSCH resource index;
[0162] Mapped to different reference signal resources, such as different SSB indexes, or different CSI-RS indexes, or different preambles, or different Msg A resource indexes, or different Msg A PUSCH resource indexes.
[0163] That is, a set of SRS resources may include different types of SRS resources, or only include the same type of SRS resources, or include SRS resources mapped to the same reference signal resource, or may also include SRS resources mapped to different reference signal resources.
[0164] Therefore, through this embodiment, the type of SRS resources in the set of SRS resources configured by the uplink configuration information and the reference signal resources to which the set of SRS resources is mapped are clarified, and a more flexible configuration of the set of SRS resources can be achieved.
[0165] In some embodiments, the set of SRS resources configured by the uplink configuration information is used for repeated transmission of SRS. Optionally, the set of SRS resources configured by the uplink configuration information is used for repeated transmission during the initial transmission of SRS, or the set of SRS resources configured by the uplink configuration information is used for repeated transmission during the retransmission of SRS.
[0166] In some embodiments, the uplink configuration information is a common configuration information, where the common configuration information is used to configure SRS resources on the uplink subband and SRS resources on non-uplink subbands, or the common configuration information is used to configure a set of SRS resources on the uplink subband and a set of SRS resources on non-uplink subbands. For example, the SRS resources on non-uplink subbands may be SRS resources on uplink time units. Another example is that the SRS resources on non-uplink subbands may be SRS resources on time units containing flexible symbols.
[0167] That is, the same SSRS resource configuration (i.e., the common SRS resource configuration) can be used to configure two possible types of SRS resources, namely: SRS resources on the UL subband and SRS resources on non-UL subbands.
[0168] In some embodiments, the uplink configuration information is two independent configuration information. Among them, the two independent configuration information are respectively used to configure SRS resources on the uplink subband and SRS resources on non - uplink subbands, or the two independent configuration information are respectively used to configure a set of SRS resources on the uplink subband and a set of SRS resources on non - uplink subbands. For example, the SRS resources on non - uplink subbands can be SRS resources on uplink time units. Another example, the SRS resources on non - uplink subbands can be SRS resources on time units including flexible symbols.
[0169] That is to say, two independent SRS resource configurations can be used to configure two possible types of SRS resources respectively. For example, one SRS resource configuration is used to configure the SRS resources on the UL subband; another SRS resource configuration is used to configure the SRS resources on non - UL subbands.
[0170] In some embodiments, the SRS resources configured by the uplink configuration information are associated with the reference signal in at least one of the following ways:
[0171] At least two different SRS resources are independently associated with the reference signal, that is, at least two different SRS resources are independently mapped with the reference signal;
[0172] At least two different types of SRS resources are independently associated with the reference signal, that is, at least two different types of SRS resources are independently mapped with the reference signal;
[0173] At least two different SRS resources are associated with the reference signal together, that is, at least two different SRS resources are mapped with the reference signal together;
[0174] At least two different types of SRS resources are associated with the reference signal together, that is, at least two different types of SRS resources are mapped with the reference signal together;
[0175] The SRS resource is not associated with the reference signal that overlaps with the SRS resource in the time domain.
[0176] Exemplarily, taking the reference signal as the SSB as an example, at least two different SRS resources are independently associated with the reference signal. For example, it can be as follows: SRS resource 1 is associated with SSB 0, SRS resource 2 is associated with SSB 1, SRS resource 3 is associated with SSB 0, and SRS resource 4 is associated with SSB 1. In this example, a reference signal may be associated with at least SRS resources as soon as possible. For example, some SRS resources are on the uplink subband (ULsubband), and some SRS resources are in the normal uplink bandwidth (UL band). In this way, a group of SRS resources that are more temporally compact and associated with the same reference signal can be selected, which is beneficial to completing multiple SRS transmissions / repetitions with low latency.
[0177] Exemplarily, taking the reference signal as the SSB as an example, at least two different types of SRS resources are independently associated with the reference signal. For example, it can be as follows: The SRS resources configured on the uplink subband of the downlink slot and the uplink SRS resources on the uplink slot or flexible slot are independently associated with the SSB resources.
[0178] Exemplarily, taking the reference signal as the SSB as an example, at least two different types of SRS resources are independently associated with the reference signal. For example, it can be as follows: The SRS resources existing in the time slot with flexible symbols are associated with SSB 0, the SRS resources existing on the uplink subband of the downlink time slot are associated with SSB 1, and the SRS resources not on the uplink subband of the downlink time slot are associated with SSB 3; Another example is that the SRS resources existing in the time slot with flexible symbols are associated with the SSBs with odd positions, and the SRS resources existing on the uplink subband of the downlink time slot are associated with the SSBs with even positions. In this example, a reference signal may be associated with at least two different types of SRS resources as soon as possible. For example, some SRS resources are on the uplink subband (ULsubband), and some SRS resources are in the normal uplink bandwidth (UL band). In this way, a group of SRS resources that are more temporally compact and associated with the same reference signal can be selected, which is beneficial to completing multiple SRS transmissions / repetitions with low latency.
[0179] Exemplarily, taking the reference signal as the SSB as an example, at least two different SRS resources are associated with the reference signal together. For example, it can be as follows: With respect to the SSB resources, SRS resources are configured. Some SRS resources are on the uplink subband of the downlink slot, and some SRS resources are in the normal uplink slot or flexible slot. The association between the SSB and the SRS is carried out in a certain order, without distinguishing what kind of slot the SRS is in. The association complexity from the SSB to the SRS resources can be reduced without distinguishing different types of SRS resources.
[0180] Exemplarily, taking the reference signal as the SSB as an example, at least two different SRS resources are associated with the reference signal together. For example, it can be as follows: The SRS resources and the SSB are associated in the order of identification. For example, SRS resource 0 is associated with SSB 0, SRS resource 1 is associated with SSB 1, SRS resource 2 is associated with SSB 2, SRS resource 3 is associated with SSB 3, SRS resource 4 is associated with SSB 4, SRS resource 5 is associated with SSB 0, SRS resource 6 is associated with SSB 1, and SRS resource 7 is associated with SSB 2. In this example, the association complexity from the reference signal to the SRS resources can be reduced without distinguishing different types of SRS resources.
[0181] Exemplarily, taking the reference signal as the SSB as an example, at least two different types of SRS resources are associated with the reference signal together. For example, it can be as follows: The SRS resources and the SSB are associated in the order of identification. For example, SRS resource 0 is associated with SSB 0, SRS resource 1 is associated with SSB 1, SRS resource 2 is associated with SSB 2, SRS resource 3 is associated with SSB 3, and SRS resource 4 is associated with SSB 4. In this example, the association complexity from the reference signal to the SRS resources can be reduced without distinguishing different types of SRS resources.
[0182] Exemplarily, taking the reference signal as the SSB as an example, the SRS resource is not associated with the reference signal that overlaps with it in the time domain. For example, it can be as follows: If the SRS resource overlaps with a reference signal in the time domain, the SRS resource and the reference signal are not associated. For example, for the SRS resource on a certain subband, when a reference signal appears on the same OFDM symbol, the SRS resource can be considered invalid at this time. This can reduce the interference to the reference signal.
[0183] In some embodiments, the mapping cycle or association period or association pattern period between the SRS resources configured by the uplink configuration information and the reference signal is determined by at least one of the following methods:
[0184] Method 1: The mapping cycle or association period or association pattern period between at least two different SRS resources and the reference signal is determined independently;
[0185] Method 2: The mapping cycle, or association period, or association pattern period between at least two different types of SRS resources and the reference signal is determined independently;
[0186] Method 3: The mapping cycle, or association period, or association pattern period between at least two different SRS resources and the reference signal is determined together;
[0187] Method 4: The mapping cycle, or association period, or association pattern period between at least two different types of SRS resources and the reference signal is determined together;
[0188] Method 5: The mapping cycle, or association period, or association pattern period between the SRS resource and the reference signal is related to the period of the duplex configuration.
[0189] Optionally, for Method 1, the mapping cycle, or association period, or association pattern period between different SRS resources and the reference signal may be the same, or may also be different.
[0190] Optionally, for Method 2, the mapping cycle, or association period, or association pattern period between different types of SRS resources and the reference signal may be the same, or may also be different.
[0191] Optionally, for Mode 3, the mapping cycle or association period or association pattern period between the at least two different SRS resources and the reference signal is a common value determined according to the mapping cycle or association period or association pattern period between all SRS resources and the reference signal.
[0192] For example, in the case where at least two different SRS resources are independently mapped to the reference signal, the mapping cycle or association period or association pattern period between the at least two different SRS resources and the reference signal is the maximum value among the mapping cycles or association periods or association pattern periods between all SRS resources and the reference signal.
[0193] Optionally, for Mode 4, the mapping cycle or association period or association pattern period between the at least two different types of SRS resources and the reference signal is a common value determined according to the mapping cycle or association period or association pattern period between all types of SRS resources and the reference signal.
[0194] For example, in the case where at least two different types of SRS resources are independently mapped to the reference signal, the mapping cycle or association period or association pattern period between the at least two different types of SRS resources and the reference signal is the maximum value among the mapping cycles or association periods or association pattern periods between all types of SRS resources and the reference signal.
[0195] In some embodiments, the mapping cycle between the SRS resource and the reference signal is the time for mapping at least once all the reference signals of the preconfigured indexes.
[0196] In some embodiments, the association period between the SRS resource and the reference signal is the shortest time for mapping at least once all the reference signals of the preconfigured indexes and being an integer multiple of the SRS period.
[0197] In some embodiments, the association pattern period between the SRS resource and the reference signal is an integer multiple of the association period between the SRS resource and the reference signal, and is the time for forming a pattern in the mapping between the SRS resource and the reference signal. Optionally, the time for forming a pattern in the mapping between the SRS resource and the reference signal is less than or does not exceed a preset time. The preset time may be specified by a protocol or configured by a network-side device.
[0198] In some embodiments, the uplink configuration information is used to configure an SRS resource set, and the uplink configuration information is further used to configure at least one of a time window and a period of the SRS resource set.
[0199] For example, the SRS resource set configured by the uplink configuration information is used for repeated transmission of SRS, and the time window of the SRS resource set may be the time window for repeated transmission of SRS.
[0200] Therefore, in the embodiments of the present application, a network-side device may configure an SRS resource or an SRS resource set in a duplex mode for a terminal. Further, the terminal may perform SRS transmission based on the SRS resource or the SRS resource set in the duplex mode, which improves the utilization rate of system resources and can also reduce the transmission delay of SRS. Moreover, the terminal may determine the duplex configuration based on the SRS resource configuration or the SRS resource set configuration of the network-side device. In this way, it is not necessary for the network-side device to perform duplex configuration through a separate signaling, making the duplex configuration more flexible.
[0201] In addition, the embodiments of the present application may support flexible duplex configuration in the idle state / inactive state, the mapping of the reference signal to the SRS resource (such as the CG PUSCH resource), which reduces the delay of SRS transmission. Moreover, dynamically configuring the SRS resource or the SRS resource set based on the uplink configuration information can improve the resource utilization rate to a greater extent.
[0202] The SRS resource configuration method provided by the embodiments of the present application may be executed by a duplex configuration determination device, or a processing unit in the duplex configuration determination device for executing the SRS resource configuration method. In the embodiments of the present application, taking the duplex configuration determination device executing the SRS resource configuration method as an example, the duplex configuration determination device provided by the embodiments of the present application is described.
