Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a transmission method, apparatus, terminal, and network-side equipment. Background Technology

[0002] To improve resource utilization, handover schemes have been proposed. These schemes are used for uplink transmission and are called uplink switching. For uplink switching, the downlink (DL) links of all uplink carriers are always available for transmission to the User Equipment (UE). The UE can determine whether to perform an uplink handover based on the uplink scheduling received from the downlink. However, unlike uplink switching, for downlink switching, the downlink is not always available, including the downlink of the primary cell (PCell). Therefore, the UE cannot monitor all downlink time slots on all component carriers (CCs). It is evident that there is currently no corresponding solution in related technologies for how to perform transmission in downlink handover scenarios. Summary of the Invention

[0045] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0046] I. Downlink Carrier Switching

[0047] Throughout the development of carrier aggregation technology, operators have maintained a high level of attention to aggregating low-frequency band spectrum, including in LTE and NR specifications. Some operators previously submitted a proposal in RP-241537, raising the following questions:

[0048] Some operators possess substantial mid-band spectrum (approximately 300MHz), which performs well near their sites. However, these operators have limited low-band spectrum (15MHz), despite its longer propagation distance. Customers spend more time within low-band coverage areas when moving between sites in urban and rural areas. Low-band carries a significant amount of traffic in both urban and rural areas. On average, these operators' customers spend 15% of their time in urban low-band and 50% in rural low-band each day. Low-band capacity limitations have a significant impact on customer experience. Due to low-band congestion, users will experience slower data rates.

[0049] Low-band carrier aggregation (CA) is a potential solution, but original equipment manufacturers (OEMs) face challenges in supporting it, and the ecosystem is currently underdeveloped. Therefore, considering the current state of existing mobile phone RF front-end architectures, operators have requested 3GPP to study and develop solutions based on handover schemes to accommodate relevant limitations, such as the proposal adopted in RP-243317, which will study the following:

[0050] This section describes the physical layer procedures and requirements for enabling low-frequency band carrier aggregation via handover, with the following specific objectives:

[0051] - Specify UE requirements, including at least a handover interval (if necessary), and the corresponding physical layer procedures, to allow handover between {Scenario 1 (case 1), Scenario 2 (case 2)}:

[0052] -case1: Transmission / reception is performed on Frequency Division Duplexing (FDD) carrier 1, while reception is not performed on Supplemental Downlink (SDL) carrier 2.

[0053] -case2: Reception is performed on SDL carrier 2, while no transmission / reception is performed on FDD carrier 1;

[0054] -RAN1 specifies a semi-static handover pattern only according to Radio Resource Control (RRC) configuration, and coordinates with RAN2 and RAN4 as necessary;

[0055] - Specifies the delay and time mask for carrier switching;

[0056] - Specify the necessary Radio Resource Management (RRM) requirements;

[0057] - Define the corresponding user equipment capabilities;

[0058] - Consider the following deployment constraints:

[0059] - The carrier frequency is <1GHz in all cases;

[0060] - The network deployment of two carriers is co-located and synchronous;

[0061] - The two carriers are located in the same Time Advance Group (TAG) (single TAG);

[0062] - The subcarrier space (SCS) between the two carriers is 15 kHz.

[0063] The above handover-based solution is advantageous in the following two scenarios:

[0064] Scenario 1 (see Figure 2aDue to the proximity of downlink and uplink spectrum, some frequency band combinations cannot be paired, such as n12-n29, n26-n106, and n28-n67. Filter-based solutions are not feasible in these situations. For example, band n29 lies within the duplex gap of band n12, leaving only a 1MHz filter stopband between the uplink (UL) of n12 and the downlink (DL) of n29. There is only a 2MHz gap between the DL of band n26 and the UL of band n106. The DL of band n67 overlaps with the UL of n28. Based on current duplexer technology, solutions based on traditional carrier aggregation architectures are not feasible. Therefore, a handover-based solution can utilize the downlink of band n29.

[0065] Scenario 2 (see Figure 2b In Scenario 2, some frequency band combinations are geographically distant. For example, combining bands n5 and n29, or n14 and n29, or n71 and n29 using a single antenna. While this frequency separation usually doesn't pose design challenges, optimizing the radiation performance of both bands simultaneously can be challenging due to their frequency separation. Adding antenna elements to support these combinations increases cost and RF architecture complexity. Therefore, a handover-based solution can utilize the downlink of the n29 band.

[0066] The handover scheme currently specified by 3GPP is for uplink transmission and is called uplink switching. However, the handover schemes for scenarios 1 and 2 are for downlink transmission (Network (NW) equipment) and downlink reception (UE).

[0067] In 3GPP-defined uplink handover, the downlink (DL) links of all uplink carriers are always available for transmission to the UE. The UE can determine whether to perform an uplink handover based on the uplink scheduling received from the downlink, minimizing the impact on the UE's physical layer operations. However, unlike uplink handover, for the downlink handover schemes in scenarios 1 and 2 below, the downlink is not always available, including the downlink of the PCell. Therefore, the UE will not be able to monitor all downlink time slots on all CCs, requiring enhancements to the existing protocol specifications to achieve handover between the following two scenarios.

[0068] Scenario 1 (Case 1): Carrier 1 has uplink transmission with 1 antenna and downlink reception with 2 antennas (1Tx / 2Rx), while carrier 2 has neither uplink transmission nor downlink reception (0Tx / 0Rx).

[0069] Scenario 2: There is no uplink transmission or downlink reception on carrier 1 (0Tx / 0Rx), and there is only downlink reception with 2 antennas on carrier 2 (0Tx / 2Rx).

[0070] Based on this, the embodiments of this application provide a transmission method that can be applied to downlink handover scenarios, such as the UE switching between scenario 1 and scenario 2, such as switching from scenario 1 to scenario 2; or switching from scenario 2 to scenario 1.

[0071] It should be noted that scenarios 1 and 2 described above are merely examples of downlink handover scenarios. The embodiments of this application can also be applied to other downlink carrier handover scenarios, and are not limited to scenarios 1 and 2. Furthermore, the aforementioned downlink handover can also be referred to as carrier handover or downlink carrier switching, etc.

[0072] The transmission method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0073] Please see Figure 3 , Figure 3 This is a flowchart of a transmission method provided in an embodiment of this application. This method can be executed by a terminal, such as... Figure 3 As shown, it includes the following steps:

[0074] Step 301: The terminal receives first configuration information from the network-side device. The first configuration information is used to configure at least one of the following: a switching pattern, an effective time of a first object, and an ineffective time of a first object. The switching pattern is used to indicate the cell, carrier, or scenario in which the terminal operates in at least one time unit in the time domain. The carrier in which the terminal operates is different under different scenarios. The first object includes at least one cell, carrier, or scenario in which the terminal is configured or activated.

[0075] In this embodiment, the switching pattern can also be referred to as a switching mode, carrier or scene operating mode, downlink switching mode, downlink carrier switching mode, or downlink scene switching mode, etc. The time unit can include at least one symbol, at least one time slot, at least one sub-time slot, or at least one subframe, etc. The scene can reflect the carrier on which the terminal operates; different scenes result in different carriers, frequency bands, or frequency domain ranges on which the terminal operates. For example, the scene can include scene 1 and scene 2. In scene 1, uplink transmission with one antenna and downlink reception with two antennas (1Tx / 2Rx) can be performed on carrier 1, while there is no uplink transmission or downlink reception on carrier 2 (0Tx / 0Rx). In scene 2, there is no uplink transmission or downlink reception on carrier 1 (0Tx / 0Rx), while downlink reception with only two antennas (0Tx / 2Rx) can be performed on carrier 2. It is understandable that when the terminal is working in scenario 1, the UE only needs to transmit (TX) / receive (RX) on carrier 1 and does not need to perform RX on carrier 2; when the terminal is working in scenario 2, the terminal only needs to perform RX on carrier 2 and does not need to perform TX / RX on carrier 1.

[0076] It should be noted that although the embodiments in this application refer to it as downlink handover, downlink carrier handover, downlink cell handover, or downlink scenario handover, if the carrier / cell / scenario involved in the handover is an FDD frequency band, then since the FDD uplink frequency band / cell is coupled, when the UE switches the downlink carrier / cell / scenario, the corresponding uplink carrier / cell / scenario will also switch. For example, in the above scenarios 1 and 2, scenario 1 can have both uplink and downlink transmissions, while scenario 2 can only have downlink transmissions.

[0077] The effective time of the aforementioned cell, carrier, or scenario can also be referred to as the dwell time, working time, or activation time of the aforementioned cell, carrier, or scenario. The ineffective time of the aforementioned cell, carrier, or scenario can also be referred to as the non-dwell time, non-working time, or inactive time of the aforementioned cell, carrier, or scenario. It is understood that for a cell, carrier, or scenario operating within a single time unit, that time unit can be considered the effective time of that cell, carrier, or scenario; correspondingly, that time unit is the ineffective time of other cells, other carriers, or other scenarios. For example, if the cell, carrier, or scenario operating in time unit 1 is cell 1, carrier 1, or scenario 1, then time unit 1 is the effective time of cell 1, carrier 1, or scenario 1, and time unit 1 is the ineffective time of other cells, other carriers, or other scenarios besides cell 1, carrier 1, or scenario 1.

[0078] The aforementioned handover pattern can be used to indicate the cell, carrier, or scenario in which the terminal operates in at least one time unit in the time domain. In an optional implementation, the network-side device can configure the cell, carrier, or scenario in which the terminal operates in each time unit in the time domain. In this case, the aforementioned handover pattern can be used to indicate the cell, carrier, or scenario in which the terminal operates in each time unit in the time domain, for example, as shown in... Figure 4 As shown, the network-side device configures which cell, carrier, or scenario the terminal operates on in different time units in the time domain. In another optional implementation, the network-side device can configure only the cell, carrier, or scenario the terminal operates on in some time units in the time domain, while the remaining time units can operate on other cells, carriers, or scenarios according to regulations or rules. For example, the network-side device only configures which time units the terminal operates on in cell 1, carrier 1, or scenario 1, while the remaining time units are configured by default for cell 2, carrier 2, or scenario 2.

[0079] For example, when a terminal receives a handover pattern, it can determine at least one of the effective time and ineffective time of each cell, carrier, or scenario based on the handover pattern, and then perform at least one of uplink transmission and downlink reception based on at least one of the effective time and ineffective time of each cell, carrier, or scenario.

[0080] The effective time and ineffective time of at least one cell, carrier, or scenario in which the terminal is configured or activated may include at least one of the effective time and ineffective time of each cell, carrier, or scenario in which the terminal is configured or activated; or, it may include at least one of the effective time and ineffective time of some cells, carriers, or scenarios in which the terminal is configured or activated. For example, it may only include at least one of the effective time and ineffective time of the cells, carriers, or scenarios in which the terminal is configured or activated for downlink handover or participates in downlink handover. For example, if the UE is configured with CA in three cells, namely cell0, cell1, and cell2, and handover only occurs between cell0 and cell2, with cell1 not participating in handover, in this case, only at least one of the effective time and ineffective time of cell0 and cell2 may be configured, while at least one of the effective time and ineffective time of cell1 may not be configured.

[0081] In some optional embodiments, the handover time may be included within the effective time of a cell, carrier, or scenario. In this case, only the effective time and ineffective time of the cell, carrier, or scenario are included in the time domain. In other optional embodiments, the handover time may not be included within the effective time of any single cell, carrier, or scenario. In this case, the handover time is included in the time domain in addition to the effective or ineffective time of the cell, carrier, or scenario. Here, the aforementioned handover time refers to the time used for cell, carrier, or scenario handover.

[0082] For example, network-side devices can configure first configuration information for terminals via RRC signaling.

[0083] In this embodiment, during downlink carrier handover, the UE can switch between different scenarios (cases). This can be achieved by configuring a semi-static carrier handover pattern using RRC. The UE determines the carrier / cell / case to operate in at least one time unit or the effective time for each carrier / cell / case based on the semi-statically configured handover pattern. For example, the UE determines, based on the first configuration information configured by RRC, to operate in case 1 within time unit n and in case 2 within time unit m, where n is not equal to m. Case 1 and case 2 can be as follows:

[0084] Case 1: Transmission / reception (TX / RX) is performed on FDD carrier 1 (carrier 1), while reception (RX) is not performed on SDL carrier 2 (carrier 2);

[0085] Case 2: Receive (RX) on SDL carrier2, but do not transmit / receive (TX / RX) on FDD carrier1.

[0086] Specifically, when the UE is operating in case 1, the UE only needs to perform TX / RX on carrier 1 and does not need to perform RX on SDL carrier 2; when the UE is operating in case 2, the UE only needs to perform RX on SDL carrier 2 and does not need to perform TX / RX on carrier 1.

[0087] Step 302: The terminal transmits information according to the first configuration information.

[0088] In this step, the terminal can perform at least one of uplink transmission and downlink reception based on the first configuration information. For example, the terminal can learn at least one of the valid time and invalid time of the first object based on the first configuration information, and then perform at least one of uplink transmission and downlink reception based on the valid time and invalid time of the first object. For instance, the terminal can determine whether to perform downlink reception / uplink transmission based on whether the time domain resources for downlink reception / uplink transmission overlap with the invalid time of its corresponding cell / carrier / scenario within its valid time or with the invalid time of its corresponding cell / carrier / scenario.

[0089] In this embodiment, the terminal receives first configuration information from a network-side device. This first configuration information configures at least one of the following: a handover pattern, a valid time for a first object, and an invalid time for the first object. The handover pattern indicates the cell, carrier, or scenario in which the terminal operates in at least one time unit in the time domain. The carrier operated by the terminal differs under different scenarios, and transmission is performed according to the first configuration information. Since at least one of the valid and invalid times for the first object can be known based on the first configuration information, uplink transmission and / or downlink reception based on the first configuration information when downlink handover is configured on the terminal helps reduce unnecessary transmission and / or reception behaviors, thereby reducing the terminal's power consumption and improving the effectiveness of the communication system.

[0090] Optionally, the terminal transmits information according to the first configuration information, including at least one of the following:

[0091] When the terminal is configured or scheduled to receive a third object on a second object, the terminal may receive or not receive the third object based on the relationship between the reception time of the third object and the first time of the second object.

[0092] When the terminal is configured or scheduled to send the fifth object on the fourth object, the terminal sends or does not send the fifth object based on the relationship between the sending time of the fifth object and the second time of the fourth object.

[0093] Wherein, the second object is a first cell or a first carrier, the first time of the second object includes at least one of valid time and invalid time, and the third object includes at least one of semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH), channel state information reference signal (CSI-RS), PDSCH and synchronous signal block (SSB);

[0094] The fourth object is a second cell or a second carrier, the second time of the fourth object includes at least one of an effective time and an ineffective time, the fifth object includes at least one of a Sounding Reference Signal (SRS) and an uplink transmission channel, the uplink transmission channel includes at least one of a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Sharing Channel (PUSCH);

[0095] The first time of the second object and the second time of the fourth object are determined based on the first configuration information.

[0096] In this embodiment, the first cell or first carrier can be any cell or carrier, or any cell or carrier configured with downlink handover. Similarly, the second cell or second carrier can also be any cell or carrier, or any cell or carrier configured with downlink handover.

[0097] The receiving time of the third object mentioned above can be understood as the receiving time configured for the third object. Similarly, the sending time of the fifth object mentioned above can be understood as the sending time configured for the fifth object.

[0098] The relationship between the reception time of the third object and the first time of the second object can be used to reflect whether the reception time of the third object overlaps with the ineffective time of the second object or whether the reception time of the third object is within the effective time of the second object. Therefore, the terminal can decide whether to receive the third object based on the relationship between the reception time of the third object and the first time of the second object. This helps to reduce some unnecessary reception behaviors, thereby reducing terminal processing or power consumption.

[0099] The relationship between the sending time of the fifth object and the second time of the fourth object can be used to reflect whether the sending time of the fifth object overlaps with the ineffective time of the fourth object or whether the sending time of the fifth object is within the effective time of the fourth object. Therefore, the terminal can decide whether to send the fifth object based on the relationship between the sending time of the fifth object and the second time of the fourth object. This helps to reduce some unnecessary sending behaviors, thereby reducing terminal processing or power consumption.

[0100] Among them, at least one of the invalid time and valid time of the second object is determined according to the first configuration information; at least one of the invalid time and valid time of the fourth object is determined according to the first configuration information.

[0101] Optionally, the step of receiving or not receiving the third object based on the relationship between the receiving time of the third object and the first time of the second object includes at least one of the following:

[0102] If the reception time of the third object overlaps with the invalid time of the second object, or if the reception time of the third object is not within the valid time of the second object, the third object will not be received.

[0103] If the reception time of the third object is within the valid time of the second object, the third object is received.

[0104] In this embodiment, the overlap between the reception time of the third object and the invalid time of the second object can be understood as at least partially overlapping, for example, it can include full overlap and partial overlap. The fact that the reception time of the third object is not within the valid time of the second object can be understood as the reception time of the third object not being entirely within the valid time of the second object. The fact that the reception time of the third object is within the valid time of the second object can be understood as the reception time of the third object being entirely within the valid time of the second object.

[0105] For example, if a UE is configured to receive an SPS PDSCH on a serving cell / carrier in a certain time unit, and the reception time of the SPS PDSCH overlaps with the ineffective time of the serving cell / carrier, then the UE will not receive, does not need to receive, or is not expected to receive the SPS PDSCH; if the reception time of the SPS PDSCH is within the effective time of the serving cell / carrier, then the UE will receive, needs to receive, will receive, or is expected to receive the SPS PDSCH.

[0106] For example, when a UE is configured and activated to receive periodic or semi-persistent CSI-RS on cell1 / carrier1, if cell1 / carrier1 is also configured for downlink handover, the UE will not receive, need not receive, or be expected to receive the CSI-RS during the inactive time of cell1 / carrier1. It is understood that the UE may, needs, or is expected to receive the CSI-RS during times other than the inactive time of cell1 / carrier1 (optionally including handover time).

[0107] In this embodiment, if the reception time of the third object overlaps with the ineffective time of the second object, or if the reception time of the third object is not within the effective time of the second object, the terminal does not receive the third object, thus reducing terminal power consumption; if the reception time of the third object is within the effective time of the second object, the terminal receives the third object, which helps to ensure the effective reception of the third object.

[0108] Optionally, the third object includes SPS PDSCH, and the step of receiving or not receiving the third object based on the relationship between the reception time of the third object and the first time of the second object includes:

[0109] If at least two SPS PDSCHs exist in a time unit, perform a first operation, which includes the following:

[0110] Based on the relationship between the reception time of each of the at least two SPS PDSCHs and the first time of the second object, at least one SPS PDSCH to be received is determined from the at least two SPS PDSCHs, overlap processing is performed between the at least one SPS PDSCH, and the SPS PDSCH obtained after overlap processing is received.

[0111] Perform overlap processing between the at least two SPS PDSCHs to obtain at least one SPSPDSCH to be received, and receive the first SPS PDSCH among the at least one SPS PDSCH, wherein the first SPS PDSCH is the SPS PDSCH whose reception time is within the valid time of the second object among the at least one SPS PDSCHs.

[0112] The aforementioned overlapping processing of SPS PDSCH can be understood as the overlapping processing of SPS PDSCH in related technologies. For example, it may include at least one of the following: overlapping processing of the SPS PDSCH reception time with the non-active period of semi-static UL symbols and / or cell discontinuous transmission (DTX); overlapping processing between SPS PDSCHs; overlapping processing between SPS PDSCH and Dynamic Grant (DG) PDSCH; and processing between the number of PDSCHs in a time slot and the maximum number of PDSCHs the UE can receive in a time slot. The aforementioned SPS PDSCH can also be referred to as a PDSCH without a corresponding PDCCH.

[0113] It should be noted that a UE can be configured with one or more SPS PDSCH configurations (such as SPS-config). When an SPS PDSCH configuration is activated, the UE will receive SPS PDSCH in each cycle. NR also introduces cell DTX. For each serving cell configured with cell DTX, if cell DTX is activated but not during the cell DTX activity cycle, the Media Access Control (MAC) entity does not need to instruct the physical layer to receive transport blocks on the downlink shared channel (DL-SCH) of that serving cell according to the downlink allocation configured for SPS. That is, it does not need to receive the corresponding SPS PDSCH at the SPS PDSCH resource location, and the UE does not need to detect PDCCH scrambled with a specific Radio Network Temporary Identity (RNTI). Therefore, during SPS PDSCH overlap processing, the UE will determine whether the SPS PDSCH overlaps with the non-active period of cell DTX. Overlap processing will be performed on SPS PDSCHs that do not overlap with the non-active period of cell DTX to determine the SPS PDSCH to be received by the UE. When determining the SPS PDSCH HARQ-ACK feedback, only the SPS PDSCH HARQ-ACK that overlaps with the cell DTX active period is fed back, and the SPS PDSCH HARQ-ACK that overlaps with the cell DTX inactive period is not fed back.

[0114] In one embodiment, at least one SPS PDSCH to be received or decoded can be determined first based on the relationship between the reception time of each of the at least two SPS PDSCHs and the first time of the second object. For example, SPS PDSCHs whose reception time is within the valid time of the second object can be determined as SPS PDSCHs to be received or decoded, or SPS PDSCHs whose reception time does not overlap with the invalid time of the second object can be determined as SPS PDSCHs to be received or decoded. Then, based on the SPS PDSCH overlap processing method in related technologies, the at least one SPS PDSCH can be overlapped to obtain the final SPS PDSCH to be received or decoded.

[0115] In another embodiment, the at least two SPS PDSCHs can first be overlapped based on the SPS PDSCH overlap processing method in related technologies to obtain at least one SPS PDSCH to be received or decoded; then, based on the relationship between the at least one SPS PDSCH and the first time of the second object, the SPS PDSCH that finally needs to be received or decoded can be obtained. For example, the SPS PDSCH whose reception time is within the valid time of the second object can be determined as the SPS PDSCH that finally needs to be received or decoded, or the SPS PDSCH whose reception time does not overlap with the non-valid time of the second object can be determined as the SPS PDSCH that finally needs to be received or decoded.

[0116] It should be noted that the SPS PDSCH to be received or decoded as determined above refers to the SPS PDSCH that the UE will receive or decode if there are no other restrictions or special circumstances. If there are, for example, if the PDSCH received by the UE from the DCI scheduling overlaps with the SPS PDSCH, the UE will need to perform other related processing to determine the PDSCH, channel, or signal to be received or decoded.

[0117] The following example illustrates the overlapping handling of SPS PDSCHs in a serving cell or a carrier with multiple SPS PDSCHs in a single time unit:

[0118] Method 1:

[0119] Step S11: The UE first resolves the overlap between the SPS PDSCH and semi-static UL symbols (such as UL symbols configured with tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), or the inactive period of the cell DTX, or the ineffective time of the serving cell or carrier. For example, Figure 5 As shown, SPS PDSCH1 and SPS PDSCH2 are configured in Pscell, and SPS PDSCH3, SPS PDSCH4, and SPS PDSCH5 are configured in Scell. SPS PDSCH1 and SPS PDSCH4 overlap with the invalid time of their respective corresponding cells / carriers, and the UE does not receive SPS PDSCH1 and SPS PDSCH4. Optionally, the invalid time of this serving cell or carrier may include the downlink carrier switching period and / or the valid time of other serving cells or carriers.

[0120] In addressing the overlap of ineffective time periods between an SPS PDSCH and its corresponding serving cell or carrier, if an SPS PDSCH is configured in or corresponds to a cell / carrier (e.g., cell1 / carrier1), and the configured reception time of this SPS PDSCH overlaps with the effective time and / or carrier handover / transition period of another cell / carrier (e.g., cell2 / carrier2), or the configured reception time of this SPS PDSCH does not fall entirely within the effective time of cell1 / carrier1, or the configured reception time of this SPS PDSCH overlaps with the ineffective time of cell1 / carrier1 (optionally, this overlap can include complete overlap and partial overlap), then it is determined that the SPS PDSCH will not be received. For example, as shown in... Figure 5 As shown, in step S1, the UE will determine that it will not receive SPS PDSCH1 and SPSPDSCH4.

[0121] Step S12: The UE then resolves the overlap between multiple SPS PDSCHs or the overlap between SPS PDSCHs and DG PDSCHs to determine the SPS PDSCHs to be received. It should be noted that the determined SPS PDSCHs to be received can be zero; for example, determining to receive only DG PDSCHs or determining that there are no SPS PDSCHs to be received. Optionally, this may also include resolving the issue that the number of configured PDSCHs exceeds the UE's ability to receive PDSCHs within a time unit, in order to determine the SPS PDSCHs to be received.

[0122] Specifically, the UE can determine the SPS PDSCH to be received by following these steps.

[0123] Step 120: Set j = 0, where j is the number of PDSCHs selected for decoding. Q is the set of active PDSCHs within a time slot that do not have a corresponding PDCCH transmission, for example, such as... Figure 5 As shown, Q contains SPS PDSCH2, SPS PDSCH3, and SPSPDSCH5.

[0124] Step 121: The terminal receives the PDSCH with the lowest sps-configindex configuration value in Q. Let j = j + 1, and designate the received PDSCH as the survivor PDSCH.

[0125] Step 122: The survivor PDSCH from Step 121 and any other PDSCH that overlaps (or even partially overlaps) with the survivor PDSCH from Step 121 are excluded from Q.

[0126] Step 123: Repeat steps 121 and 122 until Q is empty or j equals the number of unicast or multicast PDSCHs supported by the terminal within a time unit (e.g., time slot).

[0127] Method 2:

[0128] Step S21: The UE first resolves the overlap between SPS PDSCHs and / or the overlap between SPS PDSCHs and DG PDSCHs according to relevant technologies to determine the SPS PDSCHs to be received. Optionally, this may also include resolving the problem that the number of configured PDSCHs exceeds the UE's ability to receive PDSCHs within a time unit, to determine the SPS PDSCHs to be received. For example, in Figure 5 In this process, the UE determines that the SPS PDSCH to be received is SPS PDSCH 1 / SPS PDSCH 5.

[0129] Specifically, the UE can determine the SPS PDSCH to be received in the following way: The UE first resolves the overlap between the SPS PDSCH and the semi-static UL symbol (such as the UL symbol configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), or the inactive time of the cell DTX, and then determines the SPS PDSCH to be received according to the following steps.

[0130] Step 210: Set j = 0, where j is the number of PDSCHs selected for decoding, and Q is the set of active PDSCHs that do not have corresponding PDCCH transmissions. For example, ... Figure 5 As shown, Q contains SPS PDSCH1, SPS PDSCH2, SPS PDSCH3, SPS PDSCH4 and SPS PDSCH5.

[0131] Step 211: The terminal receives the PDSCH with the lowest sp-configindex configuration value in Q, let j = j + 1. The received PDSCH is designated as the survivor PDSCH.

[0132] Step 212: The survivor PDSCH from Step 211 and any other PDSCH that overlaps (or even partially overlaps) with the survivor PDSCH from Step 211 are excluded from Q.

[0133] Step 213: Repeat steps 211 and 212 until Q is empty or j equals the number of unicast or multicast PDSCHs supported by the terminal within a time unit (e.g., a time slot).

[0134] Step S22: The UE then determines whether the reception time configured for the SPS PDSCH determined in step S21 overlaps with the ineffective time of the serving cell or carrier corresponding to the SPS PDSCH. If the SPS PDSCH is configured in or corresponds to cell1 / carrier1, and the reception time configured for the SPS PDSCH overlaps with the effective time and / or carrier switching / transition period of another cell / carrier, such as cell2 / carrier2, or if the reception time configured for the SPS PDSCH does not fall entirely within the effective time of cell1 / carrier1, or if the reception time configured for the SPS PDSCH overlaps with the ineffective time of cell1 / carrier1 (optionally, this overlap may include complete overlap and partial overlap), then the UE determines not to receive the SPS PDSCH. For example, if... Figure 5As shown, SPS PDSCH1 overlaps with the invalid time of its cell / carrier, and the UE does not receive this SPS PDSCH.

[0135] Optionally, the third object includes CSI-RS.

[0136] Optionally, the CSI-RS can be configured by a Channel State Information (CSI) report configuration, such as the CSI-ReportConfig parameter. The CSI report configured in the above CSI report configuration can be related to a first report quantity. For example, the first report quantity can be a specific report quantity. Optionally, the above first report quantity can be predefined by the protocol, for example, a Rank Indicator (RI).

[0137] Optionally, the first CSI measurement timing associated with the CSI report is within the validity period of the second object, and the first CSI measurement timing is the most recent CSI measurement timing of the periodic or semi-persistent CSI-RS sent on the second object.

[0138] In this embodiment, the aforementioned CSI report may refer to the CSI report corresponding to the aforementioned CSI-RS, or the CSI report configured in the CSIreport configuration, etc., wherein the aforementioned CSI-RS is used for the CSI report, for example, configured in the CSIreport configuration.

[0139] The aforementioned first CSI measurement occasion occurring within the valid time of the second object can also be referred to as the aforementioned first CSI measurement occasion occurring within the valid time of the second object, or the aforementioned first CSI measurement occasion occurring within the valid time of the second object, etc.

[0140] It is understood that, in addition to meeting the condition that the first CSI measurement timing is within the effective time of the second object, other conditions may also be met, such as the first CSI measurement timing being within the active periods of cell DTX.

[0141] For example, for a CSI report associated with at least a reportQuantity (i.e., the first report quantity) containing an RI, the most recent CSI measurement opportunity (i.e., the first CSI measurement opportunity) of the upper half-continuous CSI-RS resource or periodic CSI-RS resource of the serving cell occurs during the activation time of the cell DTX of the serving cell and within the effective time of the serving cell. That is, the first CSI measurement opportunity needs to be located within both the activation time of the cell DTX of the service message and the effective time of the serving cell, or the first CSI measurement opportunity needs to be located in the overlapping area of ​​the activation time of the cell DTX of the service message and the effective time of the serving cell.

[0142] In this embodiment, the first CSI measurement time associated with the CSI report is located within the valid time of the second object, which helps to ensure the validity of the CSI measurement.

[0143] Optionally, the method further includes at least one of the following:

[0144] When the terminal receives at least one first CSI-RS transmission opportunity for each periodic or semi-persistent CSI-RS on the second object, the terminal sends a corresponding CSI report;

[0145] If the terminal does not receive at least one first CSI-RS transmission opportunity for each periodic or semi-persistent CSI-RS on the second object, the terminal may discard or not send the corresponding CSI report.

[0146] The first CSI-RS transmission occurs within the valid time of the second object.

[0147] It should be noted that, in addition to meeting the condition that the first CSI-RS transmission occasion falls within the effective time of the second object, it may also meet other conditions. For example, the first CSI-RS transmission occasion may also meet at least one of the following conditions: no later than the CSI-RS reference resource, and within the DTX activation time of the cell corresponding to the second object. It is understood that, when the second object is a cell, the first CSI-RS transmission occasion falls within the DTX activation time of that cell; when the second object is a carrier, the first CSI-RS transmission occasion may fall within the DTX activation time of the cell where that carrier resides.

[0148] For example, regarding the CSI report configuration in the CSI-ReportConfig parameter, this CSI report configuration is associated with a reportQuantity that includes at least the RI. The UE will only report the corresponding CSI report if it receives at least one CSI-RS transmission opportunity for each periodic CSI-RS resource or semi-persistent CSI-RS resource during the DTX activation time and effective time of the serving cell, and the reception time is no later than the CSI reference resource; otherwise, the UE will abandon the CSI report, for example, it will not transmit the corresponding CSI report. Here, the cell DTX of the serving cell is activated to perform channel measurements and / or interference measurements.

[0149] Optionally, the method further includes:

[0150] The terminal performs at least one of the following actions during the first non-zero power channel state information (None Zero Power CSI, NZP-CSI) period: acquiring channel measurement values ​​for CSI report calculation, and acquiring interference measurement values ​​for CSI report calculation;

[0151] Wherein, the first NZP CSI-RS timing is the most recent NZP CSI-RS timing of the periodic or semi-persistent CSI-RS sent on the second object, and the first NZP CSI-RS timing is within the valid time of the second object.

[0152] It should be noted that, in addition to satisfying the condition that the first NZP CSI-RS timing meets the requirement that the most recent NZP CSI-RS timing of the periodic or semi-persistent CSI-RS transmitted on the second object is within the effective time of the second object, the first NZP CSI-RS timing may also meet other conditions. For example, the first NZP CSI-RS timing may also meet at least one of the following conditions: no later than the CSI reference resource and within the DTX activation time of the cell corresponding to the second object.

[0153] For example, if the higher-level parameter timeRestrictionForInterferenceMeasurements in the CSI-ReportConfig parameter is set to "Configured", the terminal acquires at least one of the channel measurement and interference measurement values ​​used for CSI report calculation at the most recent and no later than the CSI reference resource timing of the DTX activation time and effective time of the serving cell.

[0154] The following examples illustrate the concept of CSI-RS as the third object:

[0155] The UE can be configured to receive periodic and / or semi-persistent CSI-RS. When the UE is configured with periodic CSI-RS or has activated semi-persistent CSI-RS, the UE needs to receive CSI-RS in each period. When the UE is configured for downlink carrier handover, and when the UE is configured or scheduled to receive periodic and / or semi-persistent CSI-RS on cell1 / carrier1, the UE does not expect to receive the periodic and / or semi-persistent CSI-RS during the inactive time of cell1 / carrier1, or when the periodic and / or semi-persistent CSI-RS overlaps with the inactive time of cell1 / carrier1.

[0156] Optionally, the report quantity associated with the CSI report corresponding to the CSI-RS is a specific report quantity, such as RI. The most recent CSI measurement of the semi-persistent CSI-RS resource or periodic CSI-RS resource on cell1 / carrier1 occurs during the validity period of the cell / carrier in the CSI report.

[0157] Optionally, for a specific report quantity, such as a CSI report for an RI, the UE reports a CSI report only when it receives at least one periodic CSI-RS or semi-persistent CSI-RS on a serving cell / carrier that is no later than the CSI-RS reference resource, within the cell DTX activation time, and within the cell / carrier's valid time. Otherwise, the UE discards the CSI report. For example, if the higher-layer parameter timeRestrictionForChannelMeasurements in the CSI-reportconfig parameter is set to "Configured", and if the serving cell / carrier is configured for carrier handover, then for a CSI report reported in slot n, the UE should obtain the channel measurements used for CSI report calculation only based on the latest NZP-CSI-RS timing associated with the CSI resource settings on the serving cell, no later than the CSI reference resource, within the serving cell / carrier's valid time.

[0158] For CSI reports, interference measurements are based on the latest CSI-IM / NZP-CSI-RS timing on the serving cell / carrier where the associated CSI resource is located, no later than the CSI reference resource, and within the valid time of the serving cell / carrier. For example, if the higher-layer parameter timeRestrictionForInterferenceMeasurements in the CSI-reportconfig parameter is set to "Configured", then if the serving cell / carrier is configured for carrier handover, for CSI reports reported in slot n, the UE should obtain the interference measurement based solely on the latest CSI-IM and / or NZPCSI-RS timing associated with the CSI resource settings on the serving cell, no later than the CSI reference resource, and within the valid time of the cell / carrier.

[0159] Optionally, for CSI-RS reception, if the UE receives a DCI-triggered CSI-RS, the CSI-RS may include at least one resource. In one implementation, the UE expects the reception time of the CSI-RS to be within the valid time of the corresponding cell or carrier. In another implementation, if the reception time of the CSI-RS is within the valid time of the corresponding cell or carrier, the UE may receive all or part of the CSI-RS triggered by the DCI. If only the reception time of the part of the CSI-RS triggered by the DCI is within the valid time of the corresponding cell or carrier, the UE may only receive the part of the CSI-RS whose reception time is within the valid time of the corresponding cell or carrier, or may not receive the CSI-RS whose reception time is not within the valid time of the corresponding cell or carrier, or the UE may not receive all the CSI-RS triggered by the DCI. In yet another implementation, the UE receives the CSI-RS at the corresponding time domain position according to the DCI's indication.

[0160] Optionally, the step of sending or not sending the fifth object based on the relationship between the sending time of the fifth object and the second time of the fourth object includes at least one of the following:

[0161] If the sending time of the fifth object overlaps with the invalid time of the fourth object, or if the sending time of the fifth object is not within the valid time of the fourth object, the fifth object will not be sent.

[0162] If the sending time of the fifth object is within the valid time of the fourth object, the fifth object is sent.

[0163] In this embodiment, the overlap between the sending time of the fifth object and the invalid time of the fourth object can be understood as at least partially overlapping, for example, it can include full overlap and partial overlap. The fact that the sending time of the fifth object is not within the valid time of the fourth object can be understood as the sending time of the fifth object not being entirely within the valid time of the fourth object. The fact that the sending time of the fifth object is within the valid time of the fourth object can be understood as the sending time of the fifth object being entirely within the valid time of the fourth object.

[0164] For example, when a UE is configured to transmit periodic / semi-persistent SRS on cell1 / carrier1, if cell1 / carrier1 is also configured for carrier switching, the UE will not transmit the SRS during the ineffective time of cell1 / carrier1.

[0165] For example, if the transmission time of a PUCCH / PUSCH on a certain cell / carrier overlaps with the invalid time of that cell / carrier, the UE will not transmit that PUCCH / PUSCH.

[0166] In this embodiment, if the transmission time of the fifth object overlaps with the ineffective time of the fourth object, or if the transmission time of the fifth object is not within the effective time of the fourth object, the fifth object will not be transmitted, thus reducing terminal power consumption; if the transmission time of the fifth object is within the effective time of the fourth object, the fifth object will be transmitted, which helps to ensure the effective transmission of the fifth object.

[0167] Optionally, the fifth object includes a first SRS, wherein the first SRS is an SRS for the first objective.

[0168] The aforementioned first objective can be predefined by the protocol or configured by the network-side device. For example, the aforementioned first objective can be channel acquisition.

[0169] In this embodiment, it is determined whether the SRS used for the first target overlaps with the ineffective time of the corresponding cell or carrier. If it overlaps with the ineffective time of the corresponding cell or carrier, the SRS is not sent; otherwise, the SRS is sent. For SRS used for other targets, it is not affected by downlink handover, that is, the SRS can be sent regardless of whether it overlaps with the ineffective time of the corresponding cell or carrier.

[0170] Optionally, the method further includes:

[0171] When the terminal is configured or scheduled to send a second SRS on the fourth object, the terminal sends the second SRS, which is an SRS for the second target.

[0172] The second objective mentioned above can be predefined by the protocol or configured by the network-side device. For example, the second objective may include positioning.

[0173] In this embodiment, the transmission of the SRS for the second target can be unaffected by downlink handover, that is, the SRS can be transmitted regardless of whether it overlaps with the ineffective time of the corresponding cell or carrier.

[0174] The following examples illustrate the concept of SRS as the fifth object:

[0175] The UE can be configured for periodic and / or semi-persistent SRS transmission, where each SRS resource set can be used for beam management, codebook, non-codebook, antenna switching, etc. When the UE is configured for periodic and / or semi-persistent SRS transmission on cell1 / carrier1, if cell1 / carrier1 is also configured for carrier switching, the UE is not expected to transmit or will not transmit the periodic / semi-persistent SRS during the inactive time of cell1 / carrier1. Optionally, the SRS is used for channel acquisition.

[0176] Optionally, for periodic / semi-persistent SRS used for positioning, if the UE determines that it needs to transmit the SRS during the ineffective time of cell1 / carrier1, the SRS transmission is not affected by downlink handover, that is, the UE still transmits the SRS.

[0177] In other words, during the ineffective time of cell1 / carrier1 with configured SRS resources, UEs configured for cell / carrier handover should not send periodic or semi-persistent SRS for channel acquisition; while SRS for positioning is not affected by cell / carrier handover.

[0178] Optionally, the fifth object includes a first uplink transmission channel, wherein the first uplink transmission channel satisfies at least one of the following:

[0179] The first uplink transmission channel is the uplink transmission channel obtained after the terminal performs overlapping processing between uplink transmission channels;

[0180] The first uplink transmission channel does not carry uplink control information (UCI);

[0181] The priority of the first uplink transmission channel meets the first preset condition;

[0182] The first uplink transmission channel is not the uplink transmission channel in the Random Access (RA) process;

[0183] The first uplink transmission channel is the configured uplink transmission channel.

[0184] In this embodiment, the above-mentioned overlapping processing between uplink transmission channels includes, for example, overlapping processing between PUCCHs and / or overlapping processing between PUCCH and PUSCH. It should be noted that the specific implementation methods of the overlapping processing between PUCCHs and / or the overlapping processing between PUCCH and PUSCH can be found in related technologies, and this embodiment does not limit them.

[0185] The first uplink transmission channel does not carry a UCI. Optionally, the UCI can be a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK).

[0186] The priority of the aforementioned first uplink transmission channel satisfies a first preset condition. For example, the priority of the aforementioned first uplink transmission channel is lower than a first preset priority, which can be predefined by the protocol or configured by the network-side device; or, the priority of the aforementioned first uplink transmission channel is the lowest. For example, if the priority is represented by a priority index, such as a priority index of 0 representing low priority and a priority index of 1 representing high priority, then the priority index of the aforementioned first uplink transmission channel can be 0.

[0187] The aforementioned first uplink transmission channel is not an uplink transmission channel in the random access process. For example, PUCCH does not carry HARQ-ACK for msg2, and PUSCH does not carry msg4.

[0188] The first uplink transmission channel mentioned above is a configured uplink transmission channel, that is, it does not have corresponding scheduled downlink control information (DCI), such as SPS PDSCH HARQ-ACK / CSI / SR PUCCH, configured grant (CG) PUSCH, etc.

[0189] In this embodiment, it is determined whether the first uplink transmission channel overlaps with the invalid time of the fourth object. If they overlap, the first uplink transmission channel may not be transmitted. Optionally, other uplink transmission channels besides the first uplink channel may be unaffected by downlink switching, that is, they may be transmitted regardless of whether they overlap with the invalid time of the fourth object.

[0190] Optionally, the UCI is a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK), and / or the priority of the UCI satisfies a second preset condition.

[0191] The priority of the aforementioned UCI satisfies the second preset condition, for example, the priority of the aforementioned UCI is higher than the second preset priority, or the priority of the aforementioned UCI is the highest, etc. For example, if the priority is represented by a priority index, such as a priority index of 0 representing low priority and a priority index of 1 representing high priority, then the priority index of the aforementioned UCI can be 1.

[0192] Optionally, the fifth object includes an uplink transmission channel, and the step of sending or not sending the fifth object based on the relationship between the transmission time of the fifth object and the second time of the fourth object includes:

[0193] When the terminal is configured or scheduled to transmit at least two uplink transmission channels, a second operation is performed, the second operation including one of the following:

[0194] Perform overlap processing between the at least two uplink transmission channels to obtain at least one uplink transmission channel to be transmitted, and transmit the second uplink transmission channel among the at least one uplink transmission channels, wherein the second uplink transmission channel is the uplink transmission channel among the at least one uplink transmission channels whose transmission time is within the effective time of the fourth object;

[0195] Based on the relationship between the transmission time of each of the at least two uplink transmission channels and the second time of the fourth object, at least one uplink transmission channel to be transmitted is determined from the at least two uplink transmission channels. Overlap processing is performed between the at least one uplink transmission channel, and the uplink transmission channel obtained after the overlap processing or the third uplink transmission channel among the uplink transmission channels obtained after the overlap processing is transmitted. The third uplink transmission channel is the uplink transmission channel among the uplink transmission channels obtained after the overlap processing whose transmission time is within the effective time of the fourth object.

[0196] If a UE is configured or scheduled to transmit multiple overlapping PUCCHs and / or PUSCHs within a single time unit, the UE needs to perform overlap processing. For example, this may involve multiplexing the UCIs carried by different PUCCHs, discarding some of the UCIs carried by a PUCCH, multiplexing some or all of the UCIs carried by a PUCCH onto a single PUSCH, or discarding or canceling the transmission of the PUCCH and / or PUSCH. When a UE is configured for carrier switching, the transmission time of a certain PUCCH and / or PUSCH may not be included in the valid time of the corresponding cell / carrier; in this case, the UE will not transmit that PUCCH / PUSCH.

[0197] For example, when there is overlap between PUCCHs and / or overlap between PUCCH and PUSCH in a time unit, the UE may perform transmission processing using any of the following methods:

[0198] Method 1: The UE first performs at least one of the following: overlapping processing between PUCCHs, overlapping processing between PUCCHs and PUSCHs, and overlapping processing between PUSCHs. Then, it determines whether the transmission time of the PUCCH and / or PUSCH after the overlapping processing is within the valid time of the corresponding cell / carrier, and decides whether to send the PUCCH and / or PUSCH.

[0199] Method 2: The UE first determines whether the transmission time of PUCCH and / or PUSCH is within the valid time of the corresponding cell / carrier. For PUCCH and / or PUSCH that are within the valid time of the corresponding cell / carrier, it performs at least one of the following: PUCCH overlap processing, PUCCH and PUSCH overlap processing, and PUSCH overlap processing. Then, it determines whether the transmission time of the PUCCH and / or PUSCH after overlap processing is within the valid time of the corresponding cell / carrier, and decides whether to transmit the PUCCH / PUSCH or directly transmit the PUCCH and / or PUSCH after overlap processing.

[0200] Optionally, the method further includes:

[0201] The terminal does not expect the transmission time of the uplink transmission channel obtained after performing the third operation to overlap with the invalid time of the fourth object;

[0202] The third operation is as follows: determining at least one uplink transmission channel to be received from the at least two uplink transmission channels based on the relationship between the transmission time of each of the at least two uplink transmission channels and the second time of the fourth object, and performing overlap processing between the at least one uplink transmission channel.

[0203] Optionally, the terminal does not expect the transmission time of the uplink transmission channel obtained after performing the third operation to overlap with the ineffective time of the fourth object, which can also be described as:

[0204] The invalid time of the fourth object does not overlap with the transmission time of the uplink transmission channel obtained after the terminal performs the third operation;

[0205] Alternatively, the transmission time of the uplink transmission channel obtained after the terminal performs the third operation is not within the invalid time of the fourth object;

[0206] Alternatively, the transmission time of the uplink transmission channel obtained after the terminal performs the third operation is within the valid time of the fourth object.

[0207] In this embodiment, the terminal does not expect the transmission time of the uplink transmission channel obtained after the overlap processing to overlap with the invalid time of the fourth object. In this case, after obtaining the uplink transmission channel obtained after the overlap processing, the uplink transmission channel obtained after the overlap processing can be transmitted directly.
