Description

[0001] This application is a divisional application of the invention patent application filed on March 31, 2021, with application number 202180000943.2 and entitled "Communication method for PUSCH, communication device for PUSCH and storage medium". Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a communication method, communication device, and storage medium for PUSCH. Background Technology

[0003] With the development of communication technology, beam-based transmission and reception are required to ensure coverage. When network devices (such as base stations) have multiple Transmission Reception Points (TRPs), multiple TRPs (Multi-TRPs) / panels can be used to provide services to terminals.

[0004] The primary purpose of TRP / PANEL applications is to improve coverage at cell edges and provide a more balanced quality of service within the service area. Data is transmitted collaboratively among multiple TRP / PANELs using different methods. From a network architecture perspective, deploying a network with a large number of distributed access points and centralized baseband processing is more conducive to providing a balanced user experience rate and significantly reducing latency and signaling overhead caused by handover. Utilizing the collaboration between multiple TRP / PANELs to transmit / receive data from multiple angles and multiple beams can better overcome various obstruction / blocking effects, ensuring the robustness of link connections. This is suitable for improving transmission quality and meeting reliability requirements in Ultra Reliable Low Latency Communication (URLLC) services.

[0005] In the R16 research phase, transmission enhancements were performed on the physical downlink shared channel (PDSCH) based on the application of multi-point cooperative transmission technology between downlink multiple TRPs / PANELs. Since data transmission involves scheduling feedback between uplink and downlink channels, enhancing only the downlink data channel in URLLC research cannot guarantee service performance. Therefore, in the R17 research, enhancements were further made to the physical downlink control channel (PDCCH), as well as the physical uplink control channel (PUCCH) and the physical uplink shared channel (PUSCH).

[0006] PUSCH enhancement based on Multi-TRP currently relies primarily on a single downlink control information (DCI) control scheme. This scheme uses two independent Sounding Reference Signal Resource Indicator (SRI) fields in DCI0_1 / 0_2, each corresponding to an SRI for a different TRP, to control PUSCH transmission for that specific TRP. For PUSCH transmission enhancement based on single DCI and multi-TRP, similar to downlink PDSCH, dynamic switching between single TRP and multi-TRP is required to better adapt to different transmission scenarios and actual channel conditions.

[0007] However, for the enhanced Multi-TRP PUSCH transmission, how to dynamically switch between single TRP and multi-TRP, and how to support flexible indication of the TRP to which the PUSCH is directed, are problems that need to be solved. Summary of the Invention

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

Figure 1 The wireless communication system shown is illustrated for network devices transmitting data with terminals based on TRP1 and TRP2, but is not intended to be limiting.

This disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0115] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and carrier sense multiple access with collision avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks. 5G networks can also be referred to as New Radio (NR). For ease of description, this disclosure may sometimes simply refer to the wireless communication network as a network.

[0116] Furthermore, the network device involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (eBY), a home base station, an access point (AP) in a Wireless Fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It can also be a gNB in ​​an NR system, or a component or part of a base station. It should be understood that the specific technology and specific device form used in the embodiments of this disclosure are not limited. In this disclosure, the network device can provide communication coverage for a specific geographical area and can communicate with terminals located within that coverage area (cell). Furthermore, when it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device.

[0117] Furthermore, the terminal involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to a user. For example, the terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones, customer premise equipment (CPE), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.

[0118] In this disclosure, data transmission between network devices and terminals is based on beamforming. Specifically, enhanced PUSCH uplink transmission between network devices and terminals can be achieved based on Multi-TRP. Currently, PUSCH transmission is primarily controlled by a single DCI. The main scheme for controlling PUSCH transmission with a single DCI involves using two independent SRI fields in DCI0_1 / 0_2, each corresponding to an SRI indication for a different TRP, to control PUSCH transmission for different TRPs.

[0119] In related technologies, PUSCH uplink transmission schemes include codebook-based uplink transmission and non-codebook-based uplink transmission schemes.

[0120] In an NR system, a network device can configure a terminal with a maximum of one Sounding Reference Signal (SRS) resource set for codebook-based uplink transmission. This is achieved by configuring one SRS resource set as a codebook. When the network device schedules the PUSCH using DCI format 0_1 ​​and has configured two SRS resources for the terminal to use for codebook-based uplink transmission, the terminal determines the precoding and transport stream number of the PUSCH based on the SRI and the Transmission Precoding Matrix Indicator (TPMI) / Transmission Rank Indicator (TRI) indicators. The terminal then maps the data stream to the port of the SRS resource indicated by the SRI for transmission. The SRI and TPMI / TRI indicators are the SRS resource indicator and precoding information and number of layers in the DCI, respectively. When an SRI is present, it can only indicate that the network device has configured one of the multiple SRS resources for codebook-based uplink transmission for the terminal. When a network device schedules PUSCH using DCI format 0_1, and the network device has only configured one SRS resource for the terminal for codebook-based uplink transmission, there is no SRI indication.

[0121] During uplink transmission, the terminal needs to precode the data using the Precoding Matrix Indicator (PMI) and Rank Indicator (RI) specified by the network side. Simultaneously, the precoded data is mapped to the corresponding antenna port according to the Spatial Relation Info (SRI) corresponding to the SRS resource. Here, RI is sometimes also called the data rank indicator or the transmission rank indicator. Those skilled in the art should understand the consistency of their meanings.

[0122] Table 1 illustrates the SRI indication method for multiple SRS resources. Table 2, using a 4-antenna port as an example, shows the signaling indication methods for TPMI and RI in single-layer transmission, indicating different UE capabilities. Here, UE capabilities are divided into three types: fully correlated, partially correlated, and uncorrelated, representing the correlation capability of the antenna port.

[0123] Table 3 corresponds to the codewords for single-layer transmission with 4 antenna ports.

[0128] Table 3

[0129]

[0130] In an NR system, a network device can configure a terminal with a maximum of one SRS resource set for non-codebook-based uplink transmission. This is achieved by configuring an SRS resource set as non-codebook. For non-codebook-based uplink transmission, the terminal sends the network device a maximum number of SRS resources that can be transmitted simultaneously. This resource set can be configured with a maximum of four SRS resources, each containing one SRS port. The network device can indicate to the terminal via SRIs (Supported Reference Indicators) one or more SRS resources for determining PUSCH precoding; the number of SRS resources corresponding to the SRI is the number of PUSCH streams. When the network device configures only one SRS resource for the terminal for non-codebook uplink transmission, DCI format 0_1 ​​does not contain an SRI, and the terminal determines the PUSCH precoding based on the configured SRS resources.

[0131] Below is a table of SRI indications for non-codebook and codebook-based transmissions in the protocol.

[0146] The aforementioned communication methods for PUSCH, whether codebook-based or non-codebook-based, can be enhanced using Multi-TRP. Currently, the main scheme for controlling PUSCH transmission based on single DCI uses two independent SRI fields in DCI0_1 / 0_2, each corresponding to an SRI indication for a different TRP, to control PUSCH transmission to that TRP. For PUSCH transmission enhancement based on single DCI and multi-TRP, dynamic switching between single TRP and multi-TRP is required to better adapt to transmission scenarios and actual channel conditions. For example, when transmitting PUSCH based on multi-TRP, the network device can quickly schedule the PUSCH transmission to use single-TRP transmission via signaling, depending on the actual channel and service conditions. Furthermore, in the case of single-TRP transmission, it is necessary to support flexible indication of which specific TRP the PUSCH is sent to.

[0147] In related technologies, the TRP to which the PUSCH is sent can be indicated based on the SRI or TPMI field. However, when using the SRI field to indicate whether the current TRP is active, a reserved codepoint can be used. However, currently, there are many cases where the corresponding SRI table does not have a corresponding reserved codepoint. Furthermore, when using a codebook-based approach, when using the TPMI field to indicate whether the current TRP is active, a reserved codepoint can be used. However, currently, there are many cases where the corresponding TPMI table does not have a corresponding reserved codepoint.

[0148] In view of this, the present disclosure provides a communication method for PUSCH. When a terminal is configured with multiple cooperative TRPs corresponding to SRS resource sets, an activation instruction is sent through a network device to configure the terminal to send PUSCH independently to a single TRP or to send PUSCH collaboratively to multiple TRPs, thereby realizing dynamic switching between single TRP and multiple TRP.

[0149] For ease of description in this embodiment, the activation instruction sent by the network device is referred to as the first activation instruction.

[0150] Figure 2 This is a flowchart illustrating a communication method for PUSCH according to an exemplary embodiment, such as... Figure 2 As shown, the communication method for PUSCH includes the following steps.

[0151] In step S11, in response to configuring multiple cooperative TRPs corresponding to SRS resource sets for the terminal, a first activation indication is sent.

[0152] The first activation indication is used to indicate the PUSCH transmission mode associated with the TRP. The PUSCH transmission mode includes the terminal independently transmitting PUSCH to a single TRP or collaboratively transmitting PUSCH to multiple TRPs.

[0153] In this embodiment of the disclosure, the terminal can be configured to send PUSCH independently to a single TRP or to send PUSCH collaboratively to multiple TRPs among the multiple cooperating TRPs configured for the terminal.

[0154] In this embodiment of the disclosure, when the network device configures multiple cooperative TRPs corresponding to SRS resource sets for the terminal, the network device sends a first activation instruction to activate the terminal to send PUSCH independently to a single TRP or to send PUSCH collaboratively to multiple TRPs in multiple cooperative TRPs, thereby realizing dynamic switching between single TRP and multiple TRPs.

[0155] In this embodiment of the present disclosure, the terminal may receive a first activation instruction and send PUSCH independently according to a single TRP activated by the first activation instruction, or send PUSCH collaboratively to multiple TRPs based on multiple TRPs activated by the first activation instruction.

[0156] Figure 3 This is a flowchart illustrating a communication method for PUSCH according to an exemplary embodiment, such as... Figure 3 As shown, the communication method for PUSCH includes the following steps.

[0157] In step S21, a first activation indication is received. The first activation indication is used to indicate the PUSCH transmission mode associated with the TRP. The PUSCH transmission mode includes the terminal independently transmitting PUSCH to a single TRP or collaboratively transmitting PUSCH to multiple TRPs.

[0158] In step S22, a PUSCH is sent independently to a single TRP activated by the first activation indication, or a PUSCH is sent collaboratively to multiple TRPs activated by the first activation indication.

[0159] In this embodiment of the disclosure, the terminal receives a first activation instruction sent by the network device for activating a single TRP or multiple TRPs, thereby enabling dynamic switching between a single TRP and multiple TRPs based on sending PUSCH independently to a single TRP or sending PUSCH collaboratively to multiple TRPs.

[0160] In the communication method for PUSCH provided in this disclosure, the multiple cooperative TRPs configured by the network device for the terminal are extended in multiple indication fields relative to a single TRP. In one embodiment, the first activation indication can be carried through the Medium Access Control (MAC) control element (CE). That is, the MAC-CE indicates whether to schedule the subsequent S-TRP or M-TRP. Based on the indication of the MAC CE, the terminal selects the corresponding number of bearer bits in DCI0_1 / 0_2 for blind detection of PDCCH.

[0161] In the communication method for PUSCH provided in this disclosure, one or more SRS resource sets can be activated via MAC CE, and each SRS resource set is associated with a different TRP. That is, one or more SRS resource sets configured for the terminal can be activated via MAC CE.

[0162] In the communication method for PUSCH provided in this disclosure, the MAC CE activates one or more SRS resource sets using at least one of the following methods:

[0163] Method 1: Indicate the identifier of one or more SRS resource sets. For example, you can notify the identifier of one or more active SRS resource sets.

[0164] Method 2: Indicate one or more SRS resource sets via a bitmap. That is, indicate the active SRS resource set via a bitmap.

[0165] Method 3: Indicate one or more SRS resource sets via codepoints. That is, indicate the active SRS resource set via codepoints.

[0166] Of course, in the communication method for PUSCH provided in this disclosure, the implementation of MAC CE activating SRS resource set is not limited to the above-mentioned methods, and other methods may also be used.

[0167] In the communication method for PUSCH provided in this disclosure, the TRP cooperative transmission state of PUSCH can be indicated by MAC-CE. The TRP cooperative transmission state includes transmitting PUSCH independently to a single TRP or cooperating with multiple TRPs. That is, in this disclosure, MAC-CE can indicate whether to enter an S-TRP or M-TRP transmission state. MAC-CE indicates the specific transmission state of the terminal, i.e., whether subsequent transmission is in S-TRP or M-TRP state. The physical layer can further select and schedule which TRP's corresponding SRS resource set is used.

[0168] In another embodiment of the communication method for PUSCH provided in this disclosure, a first activation indication can be carried through a group-common (GC)-DCI. That is, in this disclosure, the TRP cooperative transmission state of PUSCH can be indicated by GC-DCI, specifically, the GC-DCI can indicate whether PUSCH subsequently enters the S-TRP transmission state or the M-TRP transmission state.

[0169] In the communication method for PUSCH provided in this disclosure, the GC-DCI includes an information field for indicating the TRP cooperative transmission status of PUSCH, hereinafter referred to as the first information field. The first information field indicates the TRP cooperative transmission status of PUSCH. The TRP cooperative transmission status includes PUSCH transmitted independently to a single TRP (S-TRP transmission status) or PUSCH transmitted cooperatively to multiple TRPs (M-TRP transmission status).

[0170] In one implementation, responding to a TRP cooperative transmission state includes transmitting a PUSCH independently to a single TRP. A first information field is used to indicate the corresponding active SRS resource set, which is associated with the PUSCH transmission to that TRP.

[0171] In another implementation, in response to the TRP cooperative transmission state including cooperative transmission of PUSCH to multiple TRPs, the first information field is used to indicate at least one of the following: cooperative transmission state to multiple TRPs or cooperative transmission order indicating different PUSCH transmission times to multiple TRPs; correspondence between transmission parameter indication fields and PUSCH transmissions to different TRPs; and association between SRS resource sets and corresponding PUSCH transmissions to different TRPs.

[0172] In one example, when the GC-DCI indicates whether the TRP cooperative transmission status is S-TRP or M-TRP, the GC-DCI corresponds to one or two DCI fields. Furthermore, the DCI can be redefined to support TRP ordering, i.e., scheduling the corresponding TRP flip.

[0173] In this embodiment of the disclosure, the network device can use GC-DCI to notify each terminal of the transmission status (TRP cooperative transmission status) of the subsequent scheduling of PUSCH for a group of terminals using the same Radio Network Temporary Identity (RNTI). That is, it can transmit PUSCH independently to a single TRP (S-TRP transmission status) or transmit PUSCH cooperatively to multiple TRPs (M-TRP transmission status).

[0174] In one example, in this embodiment of the disclosure, 1 bit can be defined in GC-DCI to indicate whether the transmission is scheduled as S-TRP or M-TRP. For example, in Table 11, "0" represents S-TRP and "1" represents M-TRP.

[0175] Table 11

[0176] Bit field mapped to index Transmission state 0 S-TRP 1 M-TRP

[0177] Referring to Table 12, if the indicator is 2, it means the transmission is an m-TRP. If the indicator is 0, it means the transmission is a single TRP, using TRP1.

[0178] Table 12

[0179] Bit field mapped to index Transmission state 0 TRP 1 1 TRP 2 2 M-TRP 3 Reserved

[0180] Furthermore, in this embodiment of the disclosure, the GC-DCI can also specifically indicate the corresponding active SRS resource set, which is associated with the PUSCH transmission to that TRP. For example, in Table 13, the GC-DCI is defined as containing active TRP indication information. If the indication is 2, it represents an m-TRP transmission. In the DCI, the first enhanced field corresponds to SRS resource set 1 (TRP1), and the second corresponds to SRS resource set 2 (TRP2). If the indication is 3, it represents an m-TRP transmission, where the first enhanced field in the DCI corresponds to SRS resource set 2 (TRP2), and the second corresponds to SRS resource set 1 (TRP1). If the indication is 0, it represents a single TRP transmission using TRP1.

[0181] Table 13

[0182] Bit field mapped to index Transmission state 0 TRP 1 1 TRP 2 2 M-TRP(TRP1&TRP2) 3 M-TRP(TRP2&TRP1)

[0183] In this embodiment, the TRP cooperative transmission state of the PUSCH is indicated by GC-DCI, that is, the PUSCH is subsequently indicated to enter the S-TRP transmission state or the M-TRP transmission state by GC-DCI. The network device then schedules the PUSCH according to the selected transmission mode, and the terminal selects the corresponding number of bearer bits in DCI0_1 / 0_2 for blind detection of the PDCCH.

[0184] In another embodiment of the communication method for PUSCH provided in this disclosure, the first activation indication can be indicated by an independent indication field carried on the DCI.

[0185] In one embodiment, this disclosure allows for the addition of a DCI field to the DCI to indicate the TRP cooperative transmission status of the PUSCH. For example, an additional DCI field can be added to the enhanced DCI0-1 / 0-2 supporting multi-TRP transmission to indicate whether it is an S-TRP or M-TRP. For ease of description, this disclosure refers to the newly added DCI field as the first DCI field. The first DCI field indicates the TRP cooperative transmission status of the PUSCH. The TRP cooperative transmission status includes either independent transmission of the PUSCH to a single TRP or cooperative transmission of the PUSCH to multiple TRPs.

[0186] In one example, DCI is defined as a 1-bit indicator to indicate whether the transmission is scheduled as S-TRP or M-TRP. For example, in Table 14, "0" represents S-TRP and "1" represents M-TRP.

[0187] Table 14

[0188] Bit field mapped to index Transmission state 0 S-TRP 1 M-TRP

[0189] Furthermore, in the communication method for PUSCH provided in this disclosure embodiment, the TRP indicated in the first DCI field has a corresponding relationship with at least one of the signaling signals SRI, TPMI, and TPC. In this disclosure embodiment, after the terminal obtains the information corresponding to the DCI including the first DCI field, it can be further used for demodulation of fields such as SRI / TPMI / TPC, for example, the first SRI / TPMI / TPC field is enabled by default.

[0190] In the communication method for PUSCH provided in this disclosure embodiment, in response to the TRP cooperative transmission state, PUSCH is transmitted independently to a single TRP, and a first DCI field is used to indicate the active TRP. That is, the DCI defines information indicating the active TRP.

[0191] In one example, as shown in Table 15, if the first DCI field indicates 2, it represents an m-TRP transmission. If the first DCI field indicates 0, it represents a single TRP transmission using TRP1.

[0192] Table 15

[0193] Bit field mapped to index Transmission state 0 TRP 1 1 TRP 2 2 M-TRP 3 Reserved

[0194] Furthermore, in the communication method for PUSCH provided in this disclosure embodiment, the TRP indicated in the first DCI field has a corresponding relationship with at least one of the signaling signals SRI, TPMI, and TPC. In this disclosure embodiment, after the terminal obtains the information corresponding to the DCI including the first DCI field, it can be further used for demodulation of fields such as SRI / TPMI / TPC, for example, the first SRI / TPMI / TPC field is enabled by default.

[0195] The communication method for PUSCH provided in this disclosure includes PUSCH transmission to multiple TRPs in response to a TRP cooperative transmission state. A first DCI field can be used to indicate the cooperative transmission state of multiple TRPs or to indicate the cooperative transmission order of multiple TRPs.

[0196] In one example, as shown in Table 16, if the first DCI field indicates 2, it represents an m-TRP transmission. The first enhanced field in the DCI corresponds to SRS resource set 1 (TRP1), and the second corresponds to SRS resource set 2 (TRP2). If the first DCI field indicates 3, it represents an m-TRP transmission. The first enhanced field in the DCI corresponds to SRS resource set 2 (TRP2), and the second corresponds to SRS resource set 1 (TRP1).

[0197] If the first DCI field indicates 0, it represents a single TRP transmission being sent, using TRP1.

[0199] Bit field mapped to index Transmission state 0 TRP 1 1 TRP 2 2 M-TRP(TRP1&TRP2) 3 M-TRP(TRP2&TRP1)

[0200] Furthermore, in the communication method for PUSCH provided in this disclosure embodiment, the TRP indicated in the first DCI field has a corresponding relationship with at least one of the signaling signals SRI, TPMI, and TPC. In this disclosure embodiment, after the terminal obtains the information corresponding to the DCI including the first DCI field, it can be further used for demodulation of fields such as SRI / TPMI / TPC, for example, the first SRI / TPMI / TPC field is enabled by default.

[0201] It is understood that in the communication method for PUSCH provided in the embodiments of this disclosure, the specific implementation process of the first activation indication is not limited to the methods described above. Redefinition and extension of other existing DCI fields can be used to indicate whether it is S-TRP or M-TRP. That is, the first activation indication is carried through newly added or redefined DCI fields in the DCI.

[0202] Furthermore, in this embodiment of the present disclosure, by redefining / extending other DCI fields to implement the indication of S-TRP or M-TRP, the terminal can use the information obtained by demodulation for demodulation of fields such as SRI / TPMI / TPC.

[0203] The communication method for PUSCH provided in this disclosure addresses the issues of supporting dynamic switching indications for multiple TRP transmissions and single TRP transmissions under various circumstances, as well as simultaneously supporting indications of which specific TRP is active, through enhancements to MAC-CE or DCI commands, and further selectively supports the function of scheduling TRP flipping.

[0204] It is understood that the process of implementing TRP indication using the first indication information in the communication method for PUSCH provided in this disclosure can be applied to a terminal alone, or to a network device alone, or to the implementation process of PUSCH transmission through interaction between a terminal and a network device.
