[0051] It should be understood that although the terms “first” and “second” may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of the exemplary embodiments, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element. As used herein, the term “and / or” includes any and all combinations of one or more of the listed terms.

[0052] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments. As used herein, the singular forms “a,” “an,” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise. It will be further understood that, when used herein, the terms “comprising,” “including,” “having,” “containing,” and / or “encompassing” specify the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0053] In the following description and claims, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains.

[0054] As used herein, the term "wireless communication network" refers to a network that conforms to any suitable wireless communication standard, such as New Radio (NR), Long Term Evolution (LTE), LTE-A Advanced (LTE-A), Wideband Code Division Multiple Access (WCDMA), High-Speed ​​Packet Access (HSPA), etc. "Wireless communication network" may also be referred to as "wireless communication system." Furthermore, communication between network devices, between network devices and terminal devices, or between terminal devices within a wireless communication network can be performed according to any suitable communication protocol, including but not limited to Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), LTE, NR, Wireless Local Area Network (WLAN) standards (such as the IEEE 802.11 standard), and / or any other suitable wireless communication standard currently known or to be developed in the future.

[0055] As used herein, the term "TRP" refers to a network device in a wireless communication network to which terminal devices transmit and receive data and signaling. A TRP can refer to a base station (BS) or access point (AP), such as a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), an NR NB (also known as a gNB), a remote radio unit (RRU), a radio header (RH), a remote radio header (RRH), a relay, or a low-power node (such as a femtosecond, picosecond, etc.), depending on the terminology and technology applied.

[0056] The term "terminal device" refers to any terminal device capable of wireless communication. By way of example and not limitation, a terminal device may also be referred to as a communication device, user equipment (UE), subscriber station (SS), portable subscriber station, mobile station (MS), or access terminal (in). Terminal devices may include, but are not limited to, mobile phones, cellular phones, smartphones, Voice over IP (VoIP) phones, wireless local loop phones, tablet computers, wearable terminal devices, personal digital assistants (PDAs), portable computers, desktop computers, image capture terminal devices (such as digital cameras, gaming devices, music storage and playback devices), in-vehicle wireless terminal devices, wireless endpoints, mobile stations, built-in laptop equipment (LEE), laptop installed equipment (LME), USB dongles, smart devices, wireless premises equipment (CPE), etc. In the following description, the terms "terminal device," "communication device," "terminal," "user equipment," and "UE" are used interchangeably.

[0057] As another example, in the Internet of Things (IoT) scenario, a terminal device can represent a machine or other device that performs monitoring and / or measurement and transmits the results of such monitoring and / or measurement to another terminal device and / or network device. In this case, the terminal device can be a machine-to-machine (M2M) device, which in the 3GPP context can be referred to as a machine-type communication (MTC) device. As a specific example, a terminal device can be a UE that implements the 3GPP Narrowband Internet of Things (NB-IoT) standard. Examples of such machines or devices are sensors, metering devices such as power meters, industrial machinery, or household or personal appliances (e.g., refrigerators, televisions), personal wearable devices such as watches, etc. In other cases, a terminal device can represent a vehicle or other device capable of monitoring and / or reporting its operating status or other functions associated with its operation.

[0058] As used in this article, downlink (DL) transmission refers to transmission from the network device to the UE, while uplink (UL) transmission refers to transmission in the opposite direction.

[0059] Figure 1 An example wireless communication network 100 in which embodiments of the present disclosure may be implemented is illustrated. As shown, the wireless communication network 100 may include one or more TRPs, such as TRPs 110 and 120. Each TRP may be in the form of a BS, NB, eNB, gNB, virtual BS, base transceiver unit (BTS) or base station subsystem (BSS), AP, etc. The TRPs (e.g., TRPs 110 and 120) provide services to a group of UEs 102-1, 102-2, and 102-3, collectively referred to as "UE 102".

[0060] In some embodiments, the wireless communication network 100 may be an NR access network. At the Radio Access Network 1 (RAN1)-90 meeting, 3GPP has reached the following agreements shown in Table 1, which relate to the NR Physical Downlink Control Channel (PDCCH), the NR Physical Downlink Shared Channel (PDSCH), and the Uplink Control Information (UCI).

[0061] Table 1. Agreements reached at the 3GPP RAN1-90 meetings

[0062]

[0063] In the protocol shown in Table 1, some unresolved issues are identified, and the inventors of this invention have noted that in MP transmission scenarios where more than one TRP transmits to / receives from a single UE, some unresolved issues should be considered.

[0064] Figure 2A-2B The document illustrates two potential solutions for MP transport in DL. Utilizing... Figure 2A The solution shown uses a single PDCCH 201 (from TRP 210 or 220) to schedule PDSCH transmissions 202 and 203 from TRP 210 and TRP 220 to UE 230, while... Figure 2B In the illustrated scheme, there are separate PDCCHs for scheduling PDSCHs in TRPs 210 and 220. MP transmissions in the DL can be noncoherent joint transmissions (JT), which require lower channel state information (CSI) accuracy and have less stringent backhaul and synchronization requirements compared to coherent JT schemes. Furthermore, noncoherent JT achieves better capacity and coverage compared to single transmission (SP) schemes where the UE is served by a single TRP.

[0065] Figures 3A-3B Two potential solutions for MP transmission in UL are shown. Figure 3A In the illustrated scheme, UE 330 transmits HARQ ACK / NACK and / or CSI reports for both TRP 310 and TRP 320 via a single PUCCH or PUSCH 301. The single PUCCH or PUSCH 301 can be received by TRP 310, which then forwards the HARQ ACK / NACK and / or CSI to TRP 320 via a non-ideal backhaul 302. Figure 3B In the scheme shown, each transmission from UE 301 to TRP 310-320 carries a separate PUCCH or PUSCH (311 or 312) with HARQ ACK / NACK and / or CSI.

[0066] Regarding MP transmissions in UL, some unresolved issues have been observed. For example, each TRP can request the same UCI (e.g., ACK / NACK or CSI) separately, and for similar... Figure 3A As illustrated in the UL MP transmission scheme, determining the order in which multiple UCIs (e.g., two ACK / NACKs associated with DL transmissions from different TRPs) are populated into a single PUCCH or PUSCH remains a problem to be solved. Furthermore, for similar... Figure 3B The solution presented remains unresolved regarding how to determine the resources used for separate PUCCH / PUSCH transmissions.

[0067] In carrier aggregation scenarios supported by 3GPP LTE systems, the PUCCH in the primary cell is used to carry ACK / NACK for the primary cell and one or more secondary cells. According to 3GPP LTE technical specification TS 36.212 V14.4.0, multiple ACK / NACKs are included in a single PUCCH in the order determined by the carrier indicator included in the downlink control indicator (DCI) or the cell index configured via radio resource control (RRC) signaling. However, such indicators cannot be used to identify the UCI of different TRPs. Therefore, rules are needed for ordering the UCI bits in the PUCCH in MP transmission scenarios.

[0068] In view of the above, methods, apparatus, and computer-readable media for improving uplink control signal transmission have been proposed in this disclosure. Generally, in some embodiments, rules are utilized for ordering multiple UCI bits in uplink control signals (e.g., PUCCH or PUSCH) based on explicit or implicit identifiers, and ambiguity in the ordering of UCI bits in UL control signals used for MP transmission is avoided.

[0069] Figure 4 A flowchart of a method 400 for transmitting uplink control signals according to an embodiment of the present disclosure is shown. Method 400 can be, for example... Figure 1 The UE 102 shown is used for implementation. For ease of discussion, reference will be made below. Figure 1 Method 400 is described using the UE 102 and communication network 100 shown. However, embodiments of this disclosure are not limited thereto.

[0070] like Figure 4 As shown, at box 410, UE 102 receives power from the first TRP (e.g., Figure 1 The UE 102 receives the first downlink control signal from the TRP 110 shown, and at block 420, the UE 102 receives the signal from the second TRP (e.g., Figure 1The TRP 120 shown receives the second downlink control signal. Note that the first downlink control signal and the second downlink control signal may be received simultaneously or not simultaneously. For example, the first downlink control signal and the second downlink control signal may be received in different time slots (or subframes) or in different OFDM symbols in the same time slot (or subframe).

[0071] In some embodiments, the first downlink control signal and the second downlink control signal may include the physical downlink control channel (PDCCH) signal; however, the embodiments are not limited thereto.

[0072] In some embodiments, the first downlink control signal can schedule DL data transmission (e.g., PDSCH transmission) from the first TRP 110, while the second downlink control signal can schedule DL data transmission (e.g., additional PDSCH transmission) from the second TRP 120. Alternatively or additionally, in another embodiment, the first downlink control signal and the second downlink control signal can trigger CSI reports from the UE 102 for the first TRP 110 and the second TRP 120, respectively.

[0073] At block 430, UE 102 transmits uplink control signals (e.g., PUCCH or PUSCH signals) to at least one of TRP 110 and TRP 120. The uplink control signals include first control information associated with a first downlink control signal and second control information associated with a second downlink control signal. In one embodiment, the first control information may include HARQ feedback (e.g., ACK / NACK) for downlink transmissions (e.g., PDSCH transmissions) scheduled by the first downlink control signal, and / or CSI reports for the first TRP 110. Similarly, the second control information may include HARQ feedback (e.g., ACK / NACK) for downlink transmissions (e.g., PDSCH transmissions) scheduled by the second downlink control signal, and / or CSI reports for the second TRP 120.

[0074] In some embodiments, the order in which the first and second control information are located in the uplink control signals can be determined based on the roles or configurations of the first and second TRPs in the MP transmission for UE 102. For example, this order may depend on whether the first or second TRP is the primary TRP of UE 102. Figure 5AAn example is shown. In this example, it is assumed that the first TRP from which UE 102 receives the first downlink control signal 510 is the primary TRP, and the second TRP from which UE 102 receives the second downlink control signal 520 is the secondary TRP. Then, Figure 5B An example of how the first and second control information are ordered in this scenario is illustrated. In this example, in the uplink control signals, the first control information associated with the primary TRP precedes the second control information associated with the secondary TRP. In some embodiments, the primary TRP may be identified during initial access, and the UE may access the secondary TRP after accessing the primary TRP. However, it should be understood that different rules may be used in another embodiment. For example, the first control information associated with the primary TRP may follow the second control information associated with the secondary TRP.

[0075] In some embodiments, the first control information and the second control information may be included in the uplink control signal in sequence, the order of which is determined by identifiers associated with the first downlink control signal and the second downlink control signal received by the UE 102 at blocks 410 and 420.

[0076] For example, the order in which the first control information and the second control information are positioned in the uplink control signals (e.g., PUCCH or PUSCH) transmitted by UE 102 at block 430 can be determined based on the IDs used for the first TRP and the second TRP, respectively. For example, if the ID of the first TRP 110 is greater than the ID of the second TRP 120, the first control information is placed before the second control information in the PUCCH / PUSCH, and vice versa.

[0077] In some embodiments, the identifiers for the first TRP and the second TRP may include identifiers included in the first downlink control signal and the second downlink control signal, respectively, used to indicate the corresponding TRP. For example, if the first downlink control signal includes a smaller TRP ID1 and the second downlink control signal includes a larger TRP ID2, then the first control information may precede the second control information, such as... Figure 6 As shown.

[0078] In another embodiment, carrier aggregation may be supported for UE 102, and in this case, each of the first downlink control signal and the second downlink control signal may (but is not required to) include a jointly coded ID for indicating the combination of TRP and carrier. In this embodiment, the above order may be determined based on the jointly coded ID in the first downlink control signal and the second downlink control signal.

[0079] In another embodiment, the identifiers for the first TRP and the second TRP may include the IDs of the first TRP and the second TRP configured via RRC signaling.

[0080] Alternatively or additionally, the order in which the first and second control information are located in the uplink control signals (e.g., PUCCH or PUSCH) can be determined based on the identifiers of the resources used to receive the first and second downlink grants, respectively. In some embodiments, the identifiers of the resources may include identifiers of control resource sets (hereinafter also referred to as Coresets) associated with the first and second downlink control signals, respectively. Figure 7 An example is shown, according to one embodiment, for determining the order of multiple uplink control information (UCI) bits used to locate in a PUCCH / PUSCH signal. Figure 7 In the example shown, the first downlink control signal (in) Figure 7 The signal (represented as PDCCH 1) is received in the first Coreset 710, while the second downlink control signal (in...) is received in the second Coreset 710. Figure 7 (Represented as PDCCH 2) is received in the second Coreset 720. By UE 102 in Figure 4 The PUCCH / PUSCH signal 730 transmitted at box 430 includes UCI 1 associated with a first downlink control signal and UCI 2 associated with a second downlink control signal. For illustration and not limitation, UCI 1 may include ACK / NACK of PDSCH 740 scheduled by the first downlink control signal, and UCI 2 may include ACK / NACK of PDSCH 750 scheduled by the second downlink control signal. UCI 1 and UCI 2 may be positioned in the PUCCH / PUSCH in the order determined by the identifier (ID) of Coreset 710 and the ID of Coreset 720. For example, and not limitation, if the ID1 of Coreset 710 is less than the ID2 of Coreset 720, then UCI 1 may be positioned before UCI 2, and vice versa. Figure 8 An example of the bit sequence included in PUCCH / PUSCH 730 is shown. In this example, UCI 1, which is associated with Coreset ID1, is placed before UCI 2, which is associated with Coreset ID2.

[0081] The Coreset ID used to determine the order can be obtained by UE 102 via unicast and UE-specific RRC signaling, or broadcast signals such as Physical Broadcast Channel (PBCH) signals or Residual System Information (RMSI) signals.

[0082] Alternatively or additionally, in some embodiments, the identifiers of the resources used to receive the first downlink grant and the second downlink grant, respectively, may include the IDs of the PDCCH monitoring moments associated with the first downlink control signal and the second downlink control signal, respectively. That is, the IDs of the PDCCH monitoring moments associated with the first downlink control signal and the second downlink control signal, respectively, can be used for ordering control information in the uplink control signal. For example, if the first downlink control signal is associated with a PDCCH monitoring moment with ID 1 in the first OFDM symbol within the subframe, and the second downlink control signal is associated with a PDCCH monitoring moment with ID greater than 1 in the third OFDM symbol within the subframe, then the first control information is placed before the second control information in the PUCCH / PUSCH according to the ascending / descending order of the index / ID of the time resource associated with the PDCCH monitoring moment, and vice versa. In another example, if a first downlink control signal is associated with a PDCCH monitoring event in a frequency resource (e.g., one or more physical resource blocks or subcarriers) with a smaller index or ID (e.g., 1) in multiple OFDM symbols, and a second downlink control signal is associated with a PDCCH monitoring event in a frequency resource with a larger index or ID (e.g., 4) in the same OFDM symbol, then the first control information is placed before the second control information in the PUCCH / PUSCH, or vice versa, depending on the ascending / descending order of the index / ID of the frequency resource associated with the PDCCH monitoring event.

[0083] In another embodiment, the order in which the first and second control information are located in the PUCCH / PUSCH can be determined based on the identifiers of the scrambling sequences used to initialize the first and second downlink control signals, respectively. For example, the identifiers of the scrambling sequences used to initialize the first and second downlink control signals may include seeds for the scrambling sequences used to initialize the first and second downlink control signals, respectively. In one embodiment, the first control information associated with the first downlink control signal having a larger initialization seed value may precede the second control information in the PUCCH / PUSCH signal.

[0084] In some embodiments, the identifier for the scrambling sequence used to initialize the first downlink control signal and the second downlink control signal may include parameters for generating seeds for the scrambling sequences used to initialize the first downlink control signal and the second downlink control signal, respectively.

[0085] In some embodiments, alternatively, the identifier (e.g., but not limited to, a seed) used to initialize the scrambling sequence of RSs (e.g., demodulated RSs (DMRS)) associated with the first downlink control signal and the second downlink control signal can be used to determine the order.

[0086] In some other embodiments, the identifier for initializing the scrambling sequences of the first downlink control signal and the second downlink control signal may include parameters for generating seeds for initializing the scrambling sequences of the DMRS associated with the first downlink control signal and the second downlink control signal, respectively.

[0087] For example, as shown in 3GPP TS36.211 v2.0.0, the seed used to initialize the scrambling sequence of the DMRS associated with the first downlink control signal or the second downlink control signal can be obtained by the following formula:

[0088] (1)

[0089] Where C int Represents a seed, n scid and This represents the two parameters used to generate the seed. In this example, the order of the first and second control information in the PUCCH / PUSCH signal can be determined by C in equation (1) above. int n scid or The value is determined by ascending (or descending) order.

[0090] Figure 9 A flowchart of another method 900 for transmitting uplink control signals according to an embodiment of the present disclosure is shown. Method 900 can be, for example... Figure 1 The UE 102 shown is used for implementation. For ease of discussion, reference will be made below. Figure 1 The method 900 is described using the UE 102 and communication network 100 shown. However, the embodiments disclosed herein are not limited thereto.

[0091] like Figure 9 As shown, at box 910, UE 102 originates from the first TRP (e.g., Figure 1 The UE 102 receives the first downlink signal from the TRP 110 shown, and at block 920, the UE 102 receives the signal from the second TRP (e.g., Figure 1 The TRP 120 shown receives a second downlink signal. In one embodiment, both the first and second downlink signals may include a PDCCH signal. In another embodiment, both the first and second downlink signals may include a PDSCH signal.

[0092] At block 930, UE 102 transmits uplink control signals, such as PUCCH / PUSCH signals, to at least one of the first TRP and the second TRPs 110 and 120. The uplink control signals include first control information associated with a first downlink signal and second control information associated with a second downlink signal. In some embodiments, the first and second control information may be included in the uplink control signals in an order determined by IDs associated with non-conflicting RSs, which are associated with the first and second downlink signals. For illustrative purposes, some examples of RS-related IDs used to determine the order are provided below. However, it should be understood that the embodiments are not limited thereto.

[0093] In some embodiments, this order may be determined by an identifier (e.g., a seed or parameters used to generate the seed) of the scrambling sequence used to initialize the RS (e.g., DMRS) associated with the first downlink signal (e.g., PDCCH or PDSCH) and the second downlink signal (e.g., PDCCH or PDSCH). In one embodiment, in the bit sequence used for the PUCCH / PUSCH signal, the first control information associated with the larger seed value precedes the second control information associated with the smaller seed value.

[0094] In another embodiment, the seed for the scrambling sequence used to initialize the DMRS can be obtained by equation (1), and the order of the first control information and the second control information in the PUCCH / PUSCH signal can be obtained by C in equation (1). int n scid or The value is determined by ascending (or descending) order.

[0095] In another embodiment, the order can be determined by the orthogonal overlay code OCC value and / or cyclic shift value of the RS (e.g., DMRS) associated with each of the first downlink signal (e.g., PDCCH or PDSCH) and the second downlink signal (e.g., PDCCH or PDSCH). Figures 10A-10B An example is shown for sorting first and second control information based on OCC values. In this example, the DMRS of the first PDSCH signal (also known as PDSCH1) received at box 910 uses the OCC value OCC1, while the DMRS of the second PDSCH signal (also known as PDSCH2) received at box 920 uses the OCC value OCC2, as shown. Figure 10AAs shown. In one embodiment, OCC1 > OCC2, and in this case, in the uplink control signals (e.g., PUCCH or PUSCH signals), the first control information associated with the larger DMRS OCC value (OCC1) precedes the second control information associated with the smaller DMRS OCC value (OCC2), as shown. Figure 10B As shown. However, it should be understood that different rules may be used in another embodiment. For example, the first control information associated with OCC1 may follow the second control information associated with OCC2.

[0096] Alternatively or additionally, in some embodiments, the order may be determined by the index of the antenna port of the RS (e.g., DMRS) associated with each of the first and second downlink signals. For example, the first control information associated with the larger DMRS antenna port number (e.g., 1004) may precede the second control information associated with the smaller DMRS antenna port number (e.g., 1002).

[0097] As another example, the order can be determined by the index of the RS (e.g., DMRS) group associated with the first downlink signal and the second downlink signal. In one embodiment, the first control information associated with the larger DMRS group index (e.g., 2) precedes the second control information associated with the smaller DMRS group index (e.g., 1).

[0098] Tables 7.4.1.1.2-1 and 7.4.1.1.2-2 from TS 38.211 V2.0.0, copied below, specify the parameters for PDSCH DMRS configuration types 1 and 2, respectively. In both tables, the first column indicates the antenna port number p of the RS, and the second column indicates the index of the DMRS CDM group. In some embodiments, the order of the first and second control information in the PUCCH / PUSCH signal can be determined by the value of p of the corresponding DMRS associated with the first and second control information, the CDM group index, or a combination thereof.

[0103] Figure 11A flowchart of another method 1100 for transmitting uplink control signals according to an embodiment of the present disclosure is shown. Method 1100 can be, for example, Figure 1 The UE 102 shown is used for implementation. For ease of discussion, reference will be made below. Figure 1 Method 1100 is described using the UE 102 and communication network 100 shown. However, embodiments of this disclosure are not limited thereto.

[0104] like Figure 11 As shown, at block 1100, UE 102 receives a downlink signal for triggering multiple CSI reports. At block 1120, UE 102 transmits an uplink control signal (e.g., a PUCCH or PUSCH signal) that includes multiple CSI reports associated with the received downlink signal. In some embodiments, the multiple CSI reports are included in the uplink control signal in an order determined by identifiers associated with the multiple CSI reports. For illustrative purposes, some examples of identifiers associated with the multiple CSI reports are provided below. However, it should be understood that the embodiments are not limited thereto.

[0105] In an example embodiment, the order is determined by the identifier of the CSI RS resource (or resource set) associated with multiple CSI reports. Figure 12 An example is shown. In this example, two CSI reports are triggered, and the first CSI report (also known as CSI report 1) is associated with a CSI RS resource (or resource set) with index 1, while the second CSI report (also known as CSI report 2) is associated with a CSI RS resource (or resource set) with index 2. Thus, based on the ascending order of the associated CSI RS resource (or resource set) index, the first CSI report can be placed before the second CSI report in the PUCCH / PUSCH signal transmitted by UE 102 at box 1120.

[0106] In another embodiment, the order can be determined by the identifiers of the Synchronization Signal Block (SSB) resources (or resource sets) associated with the multiple CSI reports. For example, the first CSI report may be associated with the SSB resource (or resource set) at index 3, while the second CSI report may be associated with the SSB resource (or resource set) at index 1. In this case, based on the ascending order of the associated SSB RS resources (or resource sets), the first CSI report may be placed after the second CSI report in the PUCCH / PUSCH signal transmitted by UE 102 at block 1120.

[0107] Alternatively or additionally, the order of multiple CSI reports can be determined by the report configuration IDs associated with the multiple CSI reports. For example, in a PUCCH / PUSCH signal transmitted at box 1120, a CSI report associated with a smaller report configuration ID (e.g., 1, 2) can be placed before another CSI report associated with a larger report configuration ID (e.g., 3, 4, 5), such that... Figure 13 As shown.

[0108] Furthermore, in some embodiments, the report configuration ID can be divided into two groups, such as Figure 14 As shown. For example, report configuration IDs less than 3 are grouped into set 1 of TRP 1, while report configuration IDs equal to or greater than 3 are grouped into set 2 of TRP 2. In this way, based on its report configuration ID, UE 102 knows the target TRP of the CSI report.

[0109] In some embodiments, an identifier related to CSI reports and used to determine the order of CSI reports can be obtained based on an information field used to indicate the CSI report configuration in the downlink signal received by UE 102 at block 1100. For example, the identifier can be obtained based on parameters of reportTriger included in the downlink signal.

[0110] Alternatively or additionally, the identifier may be obtained by UE 102 based on a bitmap indicating the resource configuration of the CSI RS in the downlink signal received at block 1100. The downlink signal may include RRC signaling or DCI.

[0111] Figure 15 A flowchart of another method 1500 for transmitting uplink control signals according to an embodiment of the present disclosure is shown. Method 1500 can be, for example, Figure 1 The UE 102 shown is used for implementation. For ease of discussion, reference will be made below. Figure 1 Method 1500 is described using the UE 102 and communication network 100 shown. However, embodiments of this disclosure are not limited thereto.

[0112] like Figure 15 As shown, at block 1510, UE 102 receives a first downlink signal that indicates a first resource group and a first TRP (e.g., Figure 1 The TRP 110 shown is associated with the second resource group and the second TRP (e.g., Figure 1 This is associated with the TRP120 shown. The first downlink signal can be, for example, but not limited to, the PDCCH signal or the MAC-CE signal.

[0113] At box 1520, UE 102 uses resources from the first resource group to transmit a first uplink control signal (e.g., a PUCCH or PUSCH signal); at box 1530, UE 103 uses resources from the second resource group to transmit a second uplink control signal (e.g., another PUCCH / PUSCH signal).

[0114] Figure 16 An example of the association between resource groups and TRPs is shown. In this example, UE 102 is configured with a PUCCH / PUSCH resource set 1601 (i.e., the first resource group) for PUCCH / PUSCH for a first TRP (also referred to as TRP 1) and a PUCCH / PUSCH resource set 1602 (i.e., the second resource group) for PUCCH / PUSCH for a second TRP (also referred to as TRP 2). In this case, at block 1520, UE 102 can select resources from resource set 1601 associated with the first TRP for transmitting a first uplink signal. Similarly, at block 1530, UE 102 can select resources from resource set 1602 associated with the second TRP for transmitting a second uplink signal.

[0115] In one embodiment, the first downlink signal received by UE 102 at block 1510 may include RRC signaling or DCI for associating one or more PUCCH / PUSCH resource sets with each TRP.

[0116] In another embodiment, a resource set can be configured for UE 102 for its PUCCH / PUSCH transmissions, and each TRP is associated with a subset of resources in the configured resource set. In this embodiment, method 1500 may further include block 1505, where UE 102 receives a second downlink signal indicating a resource set for transmitting uplink control signals. Then, the first downlink signal received at block 1510 further indicates a subset of resources (i.e., a first resource group or a second resource group) from the resource set of each TRP. That is, the resource set includes a first resource group and a second resource group.

[0117] Figure 17An example is shown where PUCCH / PUSCH resource 1701 is configured for PUCCH / PUSCH in a first TRP, and PUCCH / PUSCH resource 1702 is configured for PUCCH / PUSCH in a second TRP. PUCCH resources 1701 and 1702 included in the PUCCH / PUSCH resource set 1700 can be distinguished by code division multiplexing (CDM), time division multiplexing (TDM), or frequency division multiplexing (FDM). In other words, each resource included in the resource set 1700, which can be obtained via the second downlink signal received at block 1505, can be identified by a CDM, TDM, or FDM index.

[0118] The embodiments are not limited to any specific content carried by the uplink control signals transmitted by UE 102 at block 1520. For illustrative purposes only, in some embodiments, the first and second uplink control signals transmitted at blocks 1520 and 1530 may include ACK / NACK of the PDSCH scheduled by the corresponding PDCCH. Alternatively or additionally, in another embodiment, the first and second uplink control signals may include CSI reports.

[0119] Now for reference Figure 18 , Figure 18 A flowchart of a method 1800 for receiving uplink control signals is shown. Method 1800 can be implemented by a first TRP, for example, Figure 1 The TRP shown is 110 or 120. For ease of discussion, the following will refer to... Figure 1 The method 1800 is described using the TRP 110 and communication network 100 shown. However, the embodiments disclosed herein are not limited thereto.

[0120] like Figure 18 As shown, at box 1810, TRP 110 sends a signal to the terminal device (e.g., Figure 1 In block 1820, TRP 110 receives uplink control signals (e.g., PUCCH or PUSCH signals) from UE 102. The uplink control signals include signals from a second TRP (e.g., UE 102). Figure 1 The uplink control signal (TRP 120) includes first control information associated with a first downlink control signal and second control information associated with a second downlink control signal. This uplink control signal can be controlled by UE 102 in... Figure 4 The same applies to the transmission at box 430. Therefore, the description of the order of uplink control signals and their control information provided herein with reference to method 400 also applies here.

[0121] For example, refer to method 400 and Figure 4 In some embodiments, the first control information and the second control information may be included in the uplink control signal in an order determined by whether the first TRP or the second TRP is the primary TRP of UE 102. For example, the first control information and the second control information may be included in the uplink control signal in such an order that the first control information associated with the primary TRP precedes the second control information associated with the secondary TRP. An example may be... Figure 5A and Figure 5B Found it.

[0122] Alternatively or additionally, in some embodiments, the order can be determined by an identifier associated with the first downlink control signal and the second downlink control signal. For illustrative purposes and not for limitation, the identifier associated with the first downlink control signal and the second downlink control signal and used to determine the order can include IDs for the first TRP and the second TRP, as referenced... Figure 6 In one embodiment, the IDs of the first TRP and the second TRP may be identifiers included in the first downlink control signal and the second downlink control signal, respectively, for indicating the corresponding TRP or indicating a combination of the corresponding TRP and the carrier (if carrier aggregation is supported). In another embodiment, the IDs of the first TRP and the second TRP may be configured via RRC signaling.

[0123] In another embodiment, the order can be determined by the identifiers of the resources used to receive the first downlink control signal and the second downlink control signal, respectively. For example, the identifiers of the resources used to receive the first downlink control signal and the second downlink control signal may include a Coreset ID associated with each of the first and second downlink control signals, as referenced in [reference]. Figure 7 and 8 As stated above.

[0124] Alternatively, the sequence can be determined by the ID of the PDCCH monitoring timing associated with each of the first and second downlink control signals, as described in reference method 400.

[0125] In another embodiment, the first control information and the second control information may be included in the uplink control signal in the following order, which is determined by an identifier (e.g., a seed or a parameter for generating a seed) of a scrambling sequence used to initialize the first downlink control signal and the second downlink control signal, or by an identifier (e.g., a seed or a parameter for generating a seed) of a scrambling sequence used to initialize RS (e.g., DMRS) associated with the first downlink control signal and the second downlink control signal, as described in reference method 400.

[0126] For example, refer to method 400 and Figure 4 The first and second control information carried in the uplink control signal may include, for example, ACK / NACK and / or CSI reports.

[0127] Figure 19 A flowchart of another method 1900 for receiving uplink control signals is shown. Method 1900 can be implemented by a first TRP, for example, Figure 1 The TRP shown is 110 or 120. For ease of discussion, the following will refer to... Figure 1 The method 1900 is described using the TRP 110 and communication network 100 shown. However, the embodiments disclosed herein are not limited thereto.

[0128] like Figure 19 As shown, at box 1910, TRP 110 sends a signal to the terminal device (e.g., Figure 1 In block 1920, TRP 110 receives uplink control signals from UE 102. The uplink signals can be transmitted by UE 102 in [the following context:] UE 102 transmits first downlink signals (e.g., PDCCH or PDSCH signals). In block 1920, TRP 110 receives uplink control signals from UE 102. Figure 9 The same is transmitted at frame 930. Therefore, refer to Figure 9 The description of the ordering of the uplink control signals and the control information within the uplink control signals provided in Method 900 also applies here, and the details will not be repeated.

[0129] In some embodiments, the uplink control signal includes first control information associated with the first downlink signal and second control information associated with the second downlink signal from a second TRP (e.g., TRP 120), and the first and second control information are included in the uplink control signal in an order determined by an identifier associated with an RS (e.g., DMRS) associated with the first and second downlink signals.

[0130] For illustrative purposes and not as a limitation, the identifier associated with an RS may include at least one of the following: an identifier (e.g., a seed or parameters for generating a seed) for initializing a scrambling sequence for each RS associated with the first downlink signal and the second downlink signal; an OCC or CS value for each RS associated with the first downlink signal and the second downlink signal; an index (or an index of the RS) of the antenna port of each RS associated with the first downlink signal and the second downlink signal; and an index of the group of RSs associated with each of the first downlink signal and the second downlink signal.

[0131] Figure 20 A flowchart of another method 2000 for receiving uplink control signals is shown. Method 2000 can be, for example... Figure 1 This is implemented using TRP 110 or 120 as shown. For ease of discussion, reference will be made below. Figure 1 The method 2000 is described using the TRP 110 and communication network 100 shown. However, the embodiments disclosed herein are not limited thereto.

[0132] like Figure 20 As shown, at box 2010, TRP 110 sends a message to the terminal device (e.g., Figure 1 In block 2020, TRP 110 receives an uplink control signal that includes multiple CSI reports associated with the received downlink signal. In some embodiments, the multiple CSI reports are included in the uplink control signal in an order determined by identifiers associated with the multiple CSI reports.

[0133] For example, the identifier associated with multiple CSI reports may include at least one of the following: the ID of the CSI RS resource (or resource set) associated with the multiple CSI reports, the ID of the SSB resource (or resource set) associated with the multiple CSI reports, and the ID of the report configuration associated with the multiple CSI reports.

[0134] In some embodiments, the identifier used to determine the order may be obtained from: an information field indicating the CSI report configuration in the downlink signal transmitted at block 2010; or a bitmap indicating the resource configuration of the CSIRS in the downlink signal.

[0135] The uplink control signal received by TRP 110 at box 2020 can be communicated with the uplink control signal received by UE 102 at box 2020. Figure 11 The same is transmitted at frame 1120, and therefore, regarding reference method 11 and Figure 11 The descriptions of uplink control signals provided also apply here.

[0136] Figure 21 A flowchart of another method 2100 for receiving uplink control signals is shown. Method 2100 may be performed by a first TRP (e.g., Figure 1 This is implemented using the TRP 110 or 120 shown. For ease of discussion, reference will be made below. Figure 1 The method 2100 is described using the TRP 110 and communication network 100 shown. However, the embodiments disclosed herein are not limited thereto.

[0137] like Figure 21As shown, at box 2110, TRP 110 sends a message to the terminal device (e.g., Figure 1 UE 102 transmits a first downlink signal. This first downlink signal indicates that a first resource group is associated with TRP 110 and a second resource group is associated with a second TRP 120. At block 2120, TRP 110 uses resources from the first resource group to receive uplink control signals from UE 102. In one embodiment, the first resource group may be a PUCCH / PUSCH resource set configured for UE 102 for PUCCH / PUSCH transmissions to TRP 110, and the second resource group may be a PUCCH / PUSCH resource set configured for UE 102 for PUCCH / PUSCH transmissions to TRP 120.

[0138] Alternatively, in another embodiment, the first resource group and the second resource group may be subsets of resources different from the PUCCH / PUSCH resource set configured for PUCCH / PUSCH transmission for UE 102. In this embodiment, at block 2105, TRP 110 may transmit a second downlink signal indicating the resource set.

[0139] Figure 22 A simplified block diagram of apparatus 2210 and apparatus 2220 is shown, wherein apparatus 2210 may be embodied as a terminal device (e.g., Figure 1 The UE 102 shown may be included in a terminal device, and the device 2220 may be embodied as a network device (e.g., Figure 1 The TRP (110 or 120) shown may be included in the network device.

PROG 2214 may include instructions that, when executed on the associated processor 2211, enable device 2210 to operate according to embodiments of the present disclosure (e.g., methods 400, 900, 1100, or 1500). Combinations of at least one processor 2211 and at least one MEM 2212 can form a processing device 2215 suitable for implementing various embodiments of the present disclosure.

PROG 2224 may include instructions that, when executed on the associated processor 2221, enable device 2220 to operate according to embodiments of the present disclosure (e.g., perform any of methods 1800-2100). Combinations of at least one processor 2221 and at least one MEM 2222 can form a processing device 2225 suitable for implementing various embodiments of the present disclosure.

[0142] Various embodiments of this disclosure may be implemented by one or more executable computer programs, software, firmware, hardware, or combinations thereof from processors 2211, 2221.

[0143] MEM 2212 and 2222 can be of any type suitable for the local technical environment and can be implemented using any suitable data storage technology, such as semiconductor-based memory devices, magnetic memory devices and systems, optical memory devices and systems, fixed memory and removable memory, as non-limiting examples.

[0145] Additionally, this disclosure may also provide a carrier containing the computer program described above. The carrier includes a computer-readable storage medium, which may be, for example, an optical disc or electronic storage device, such as RAM (random access memory), ROM (read-only memory), flash memory, magnetic tape, CD-ROM, DVD, Blu-ray disc, etc.
