Description

Technical Field

[0001] This application relates to the field of mobile communication technology, specifically to a wireless communication method, apparatus, and communication device. Background Technology

[0002] Research on New Radio (NR) systems currently focuses on two frequency bands: Frequency Range 1 (FR1) and Frequency Range 2 (FR2). As NR systems evolve, new frequency bands, those higher than FR1 and FR2, are also being studied. For ease of description, these new frequency bands are referred to as high-frequency bands.

[0003] High-frequency bands include licensed and unlicensed spectrum. Licensed spectrum can also be called non-shared spectrum, and unlicensed spectrum can be called shared spectrum. Due to the higher frequency, the channel access methods on unlicensed spectrum in high-frequency bands differ from those on unlicensed spectrum in FR1 / FR2. Currently, there is no clear solution for supporting receiver-assisted channel access methods on unlicensed spectrum in high-frequency bands. Summary of the Invention

The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0068] high frequency

[0069] The research on NR systems mainly considers two frequency bands, namely FR1 and FR2. The frequency domain ranges included in FR1 and FR2 are shown in Table 1 below.

[0070]

[0071]

[0072] Table 1

[0073] As NR systems evolve, new frequency bands, namely those higher than FR1 and FR2, are being studied. For ease of description, these new frequency bands are referred to as high-frequency bands, which can also be represented by FRX. It should be understood that this band name should not constitute any limitation; for example, FRX could be FR3. The frequency domain range included by FRX is shown in Table 2 below.

[0074] FRX 52.6GHz–71GHz

[0075] Table 2

[0076] FRX includes licensed spectrum and unlicensed spectrum. Licensed spectrum can also be called non-shared spectrum or dedicated spectrum, while unlicensed spectrum can also be called shared spectrum.

[0077] Unlicensed spectrum is spectrum allocated by a country or region for use in wireless communication. This spectrum is usually considered a shared spectrum, meaning that communication equipment in different communication systems can use the spectrum as long as it meets the regulatory requirements set by the country or region on that spectrum, without needing to apply for a proprietary spectrum license from the government.

[0078] To ensure the amicable coexistence of various communication systems using unlicensed spectrum, some countries and regions have stipulated regulatory requirements for the use of unlicensed spectrum. For example, communication devices must adhere to the "Listen Before Talk" (LBT) principle, meaning that before transmitting signals on an unlicensed spectrum channel, the device must first perform channel listening. Transmission is only permitted if the channel is idle; otherwise, transmission is prohibited. Furthermore, to ensure fairness, the duration of signal transmission on an unlicensed spectrum channel in a single transmission cannot exceed a certain time limit. Also, to prevent excessively high signal power from affecting other important signals on the same channel, communication devices using unlicensed spectrum channels must adhere to limits on maximum power spectral density. It should be noted that in some countries and regions, LBT requirements do not apply to unlicensed spectrum included in the FRX band.

[0079] The subcarrier spacing of FRX can be larger than that of FR2. Current candidate subcarrier spacings include at least one of the following: 240kHz, 480kHz, and 960kHz. As an example, the corresponding parameter sets (Numerology) for these candidate subcarrier spacings are shown in Table 3 below. In Table 3, NCP refers to the Normal Cyclic Prefix, and ECP refers to the Extended Cyclic Prefix.

[0080]

[0081] Table 3

[0082] Concepts related to shared spectrum

[0083] Maximum Channel Occupancy Time (MCOT): refers to the maximum length of time that a channel is allowed to be used for signal transmission after successful channel sensing on a shared spectrum channel.

[0084] Channel Occupancy Time (COT): This refers to the length of time a signal is transmitted using a channel after successful channel detection on a shared spectrum channel. It can also be considered as the length of time the channel is occupied after successful channel detection on a shared spectrum channel. During this time, the channel occupancy can be continuous or discontinuous, and includes the total time for signal transmission by both the device initiating the channel occupancy and the device sharing the channel occupancy.

[0085] Channel Occupancy Time (COT) of Network Devices (gNB / eNB-initiated COT): Also known as the COT initiated by the network device, it refers to the channel occupancy time obtained by the network device after successful channel detection on a shared spectrum channel. The COT initiated by the network device can be used for transmission by the network device itself, and can also be used for transmission by terminal devices under certain conditions.

[0086] UE-initiated COT: Also known as UE-initiated COT, it refers to the channel occupancy time obtained by the terminal device after successful channel detection on a shared spectrum channel. The UE-initiated COT can be used for transmission by the terminal device itself, and under certain conditions, it can also be used for transmission by network devices.

[0087] Downlink transmission burst: refers to a group of downlink transmissions (i.e., including one or more downlink transmissions) performed by a network device. This group of downlink transmissions is either continuous (i.e., there are no gaps between multiple downlink transmissions) or has gaps that are less than or equal to a preset value, such as 16 microseconds on the FR1 band. If the gap between two downlink transmissions performed by a network device is greater than the preset value of 16 microseconds, then these two downlink transmissions are considered as two separate downlink transmission bursts.

[0088] Uplink transmission opportunity (UL transmission burst): refers to a group of uplink transmissions (i.e., including one or more uplink transmissions) performed by the terminal device. This group of uplink transmissions is continuous (i.e., there are no gaps between multiple uplink transmissions), or there are gaps in the group of uplink transmissions, but the gaps are less than or equal to a preset value, for example, 16 microseconds on the FR1 band. If the gap between two uplink transmissions performed by the terminal device is greater than the preset value of 16 microseconds, then the two uplink transmissions are considered as two uplink transmission opportunities.

[0089] It should be understood that in the FRX band, the above preset value can be other values, such as 8 microseconds. This application does not limit this.

[0090] Channel detection successful: also known as LBT success or channel detection idle. For example, the energy detection during a channel listening slot is below the energy detection threshold.

[0091] Channel detection failure: also known as LBT failure or channel detection busy. For example, the energy detection during a listening slot of the channel is higher than or equal to the energy detection threshold.

[0092] Receiver-side assisted channel access method

[0093] Receiver-assisted channel access is a channel access method similar to the Request To Send / Clear To Send (RTS / CTS) mechanism in Wi-Fi systems. For example... Figure 2 As shown,

[0094] 1. Before transmitting data, network devices send an RTS signal, which is used to ask terminal devices whether they are ready to receive data.

[0095] 2. Scenario 1: After receiving the RTS signal, if channel detection is successful, the terminal device can send a CTS signal to the network device. This CTS signal informs the network device that the terminal device is ready to receive data. Optionally, the CTS signal carries the interference measurement results of the terminal device. After receiving the CTS signal, the network device can proceed with downlink transmission to the terminal device. Alternatively,

[0096] Scenario 2: If the terminal device does not receive the RTS signal or receives the RTS signal but cannot send the CTS signal due to channel detection failure, the terminal device will not send the CTS signal to the network device; if the network device does not receive the CTS signal from the terminal device, it may give up downlink transmission to the terminal device.

[0097] Channel access corresponding to unlicensed spectrum in high-frequency bands

[0098] On FRX, for countries and regions with LBT requirements, channel access methods (i.e., LBT methods) can include several types, such as omnidirectional channel access, directional channel access, receiver-assisted channel access, and channel access without channel detection (i.e., no LBT). Channel access without channel detection may be subject to certain conditions, such as Automatic Transmit Power Control (ATPC), Directional Freeze-Side (DFS), Long-Term Interference Detection (LTD), or other interference cancellation mechanisms. Furthermore, switching between channel access methods with and without channel detection is possible. For countries and regions without LBT requirements, it is also necessary to consider whether to introduce certain conditions, such as whether to apply ATPC, DFS, LTD, limit the duty cycle, limit transmit power, or limit MCOT, etc.

[0099] Because of the higher frequency band, the channel access methods on the unlicensed spectrum of the FRX band differ from those on the unlicensed spectrum of the FR1 band. For example, a transmit-receive interaction-based channel access method, also known as a receiver-assisted channel access method, can be introduced on the FRX band. To support receiver-assisted channel access on the unlicensed spectrum of the FRX band, a clear scheme is needed regarding how to send request transmission information. Therefore, the following technical solutions according to embodiments of this application are proposed. These technical solutions can be applied to, but are not limited to, the unlicensed spectrum of the FRX band.

[0100] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0101] Figure 3 This is a flowchart illustrating the wireless communication method provided in an embodiment of this application, as shown below. Figure 3 As shown, the wireless communication method includes the following steps:

[0102] Step 301: The first device receives first control information sent by the second device, the first control information including request information from at least one device, the at least one device including the first device.

[0103] Step 302: The first device determines the request to send information based on the first control information.

[0104] Step 303: The first device sends information according to the request of the first device and determines whether to send response information to the second device.

[0105] In this embodiment of the application, the second device sends first control information, and the first device receives the first control information sent by the second device. Here, the first control information includes request information from at least one device, and the at least one device includes the first device. That is, the first control information includes at least the request information from the first device, wherein the request information from the first device is used by the first device to determine whether to send response information to the second device.

[0106] In some embodiments, the first control information is downlink control information, the first device is a terminal device, and the second device is a network device. In another alternative embodiment, the first control information is sidelink control information, the first device is a first terminal device, and the second device is a second terminal device.

[0107] In this embodiment of the application, the first control information can be common control information. Here, common control information can be embodied in the following two aspects:

[0108] Firstly: The first control information corresponds to a first control information format, wherein the first radio network temporary identity (RNTI) corresponding to the first control information format is a public RNTI.

[0109] When the first control information is downlink control information, the first control information corresponds to a first downlink control information (DCI) format, and the first RNTI corresponding to the first DCI format is a common RNTI. For example, the first RNTI is a Slot Format Indicator-Radio Network Temporary Identity (SFI-RNTI). Here, the first RNTI corresponds to a group of terminal devices, wherein the group of terminal devices includes at least one terminal device.

[0110] When the first control information is sidelink control information, the first control information corresponds to a first sidelink control information (SCI) format, and the first RNTI corresponding to the first SCI format is a common RNTI. Here, the first RNTI corresponds to a group of terminal devices, wherein the group of terminal devices includes at least one terminal device.

[0111] Secondly: The first control information is transmitted through the group common control channel.

[0112] If the first control information is downlink control information, the first control information can be transmitted through the Group Common-Physical Downlink Control Channel (GC-PDCCH).

[0113] If the first control information is sidelink control information, the first control information can be transmitted through the Group Common-Physical Sidelink Control Channel (GC-PSCCH).

[0114] It should be noted that, in the case where the first control information includes request information from multiple devices, each of the multiple devices determines its request information in the same way, that is, in the same way as the first device determines its request information.

[0115] The following explains the specific information included in the request sending information of the first device.

[0116] In this embodiment, the request transmission information of the first device is used to determine at least one of the following information: first indication information, beam indication information, response resource indication information, channel access indication information, COT length information, COT end position information, frequency domain resource set indication information, time slot format indication information, and control channel monitoring set group indication information. The first indication information is used to indicate whether the second device requests transmission. It should be noted that the information determined by the request transmission information of the first device is not limited to the above-mentioned types and may also include other information.

[0117] In some embodiments, the request transmission information of the first device includes request transmission information associated with at least one cell, at least one Band Width Part (BWP), or at least one set of frequency domain resources.

[0118] Here, the request transmission information of the first device includes at least one request transmission information, each of which is associated with a cell, a BWP, or a frequency domain resource set. For example, the request transmission information of the first device includes a first request transmission information and a second request transmission information, wherein the first request transmission information is associated with a first cell, a first BWP, or a first frequency domain resource set, and the second request transmission information is associated with a second cell, a second BWP, or a second frequency domain resource set.

[0119] In some embodiments, the at least one cell refers to at least one cell in which the first device is configured.

[0120] In some embodiments, the at least one BWP includes a BWP on at least one cell in which the first device is configured. For example, the at least one BWP includes an active BWP on at least one cell in which the first device is configured.

[0121] In some embodiments, the at least one frequency domain resource set corresponds to a BWP or a cell. For example, the at least one frequency domain resource set is a set of frequency domain resources included on a BWP; or, the at least one frequency domain resource set is a set of frequency domain resources included on a cell.

[0122] In some embodiments, each frequency domain resource set in the at least one frequency domain resource set corresponds to a BWP or a cell. For example, each frequency domain resource set in the at least one frequency domain resource set corresponds to the frequency domain resources included on a BWP on which the first device is configured; or, each frequency domain resource set in the at least one frequency domain resource set corresponds to the frequency domain resources included on a cell on which the first device is configured.

[0123] In this embodiment of the application, the request sending information of the first device includes first request sending information, which is associated with a first cell, a first BWP, or a first frequency domain resource set. The first cell is the cell corresponding to the first device, the first BWP is the BWP corresponding to the first cell, and the first frequency domain resource set is the frequency domain resource set corresponding to the first BWP.

[0124] In some embodiments, the first cell is the cell corresponding to the first device. It can also be understood that the first device is configured with at least one cell, and the first cell is one of the at least one cells.

[0125] In some embodiments, the first BWP is the BWP corresponding to the first cell, or it can be understood that the first cell is configured with at least one BWP, and the first BWP is the active BWP among the at least one BWP.

[0126] In some embodiments, the first frequency domain resource set is the frequency domain resource set corresponding to the first BWP. It can also be understood that the first BWP corresponds to at least one frequency domain resource set, and the first frequency domain resource set is one of the frequency domain resource sets in the at least one frequency domain resource set.

[0127] In some embodiments, the first request sending information included in the first control information is predefined; or, the first request sending information included in the first control information is determined based on higher-level configuration parameters.

[0128] In some embodiments, the first request to transmit information includes at least one of the following: first indication information, beam indication information, response resource indication information, channel access indication information, COT length information, COT end position information, frequency domain resource set indication information, time slot format indication information, and control channel monitoring set group indication information, wherein the first indication information is used to indicate whether the second device requests transmission. It should be noted that the information included in the first request to transmit information is not limited to the above-mentioned types and may also include other information.

[0129] The following explains how the information included in the first request to send information is determined, how the position of the information included in the first request to send information is determined, and how the number of bits occupied by the information included in the first request to send information is determined.

[0130] (a) The method for determining the information included in the first request message.

[0131] In this embodiment of the application, the information included in the first request to send information is determined based on one of the following methods:

[0132] Method 1: The information included in the first request is determined based on high-level configuration parameters.

[0133] In some embodiments, where the first device is a terminal device and the second device is a network device, the higher-layer configuration parameters can be configured by the second device.

[0134] In some embodiments, where the first device is a first terminal device and the second device is a second terminal device, the higher-layer configuration parameters may be configured by a network device or a control node with management and control functions, such as a third device. In some embodiments, the third device may be a control node of the first terminal device or the second terminal device, such as the group head terminal of the terminal group to which the first terminal device belongs. In some cases, the third device and the second terminal device may be the same device. In other cases, the third device and the first terminal device may be the same device.

[0135] In some embodiments, the information to be sent in the first request can be configured through high-level configuration parameters, or the information to be sent in the first request can be configured through high-level configuration parameters to include one or more pieces of information.

[0136] The following example uses the configuration of whether the first request to be sent includes a certain piece of information, such as the first information, through high-level configuration parameters. If the first request to be sent includes multiple pieces of information, the configuration method for other pieces of information configured through high-level configuration parameters can be the same as that for the first information.

[0137] In some embodiments, the first information corresponds to a first high-level configuration parameter, and the first high-level configuration parameter can be used to configure whether the first request sending information includes the first information.

[0138] In one example, the first high-level configuration parameter takes a first value, indicating that the first request to send information includes the first information; or, the first high-level configuration parameter takes a second value, indicating that the first request to send information does not include the first information.

[0139] In one example, if the first high-level configuration parameter is configured, it means that the first request sending information includes the first information; if the first high-level configuration parameter is not configured, it means that the first request sending information does not include the first information.

[0140] In one example, the first high-level configuration parameter includes a single value, and the first request sending information does not include the first information; or, the first high-level configuration parameter includes multiple values, and the first request sending information includes the first information.

[0141] In one example, the first request sending information is configured to include the following information through high-level configuration parameters: first indication information, beam indication information, and response resource indication information.

[0142] In one example, the first request message is configured to include the following information through high-level configuration parameters: first indication information, beam indication information, and response resource indication information.

[0143] In one example, if a higher-level configuration parameter including response resource indication information is configured, the first request message includes the response resource indication information; if no higher-level configuration parameter including response resource indication information is configured, the first request message does not include the response resource indication information.

[0144] Method 2: The information included in the first request to send is predefined.

[0145] In this embodiment of the application, the information to be sent in the first request can be predefined (i.e. specified by the protocol), or it can be predefined whether the information to be sent in the first request includes one or several pieces of information.

[0146] In one example, the protocol specifies that the first request to send information includes the following: first indication information, beam indication information, and response resource indication information.

[0147] In one example, the protocol specifies whether the first request message includes the following information: first indication information, beam indication information, and response resource indication information.

[0148] Method 3: The information included in the first request to send is determined based on the spectrum attributes corresponding to the first cell.

[0149] In this embodiment of the application, the information included in the first request to send information is related to the spectrum attributes corresponding to the first cell. Based on the relationship and the spectrum attributes corresponding to the first cell, it can be determined which information is included in the first request to send information, or whether the first request to send information includes one or several pieces of information.

[0150] In one example, if the spectrum attribute corresponding to the first cell is a licensed spectrum, the first request to send information does not include the first indication information.

[0151] In one example, if the spectrum attribute corresponding to the first cell is an unlicensed spectrum, the first request to send information includes the first indication information.

[0152] Method 4: The information included in the first request to send information is determined based on the channel access mechanism corresponding to the first cell.

[0153] In this embodiment of the application, the information included in the first request to send information is related to the channel access mechanism corresponding to the first cell. Based on this relationship and the channel access mechanism corresponding to the first cell, it can be determined which information is included in the first request to send information, or whether the first request to send information includes one or several pieces of information.

[0154] Here, the channel access mechanism can include a channel access mechanism that performs channel detection (i.e., a channel access mechanism that performs LBT) and a channel access mechanism that does not perform channel detection (i.e., a channel access mechanism that does not perform LBT). Furthermore, in some embodiments, the channel access mechanism that performs channel detection can be further divided into dynamic channel access mechanism and semi-static channel access mechanism.

[0155] In one example, if the channel access mechanism corresponding to the first cell is a channel access mechanism that does not perform channel detection, the first request to send information does not include the first indication information.

[0156] In one example, if the channel access mechanism corresponding to the first cell is a channel access mechanism that performs channel detection, the first request to send information includes the first indication information.

[0157] (ii) Method for determining the location of information included in the first request message.

[0158] The position of the information included in the first request to send in the first control information is determined based on high-level configuration parameters; or, the position of the information included in the first request to send in the first control information is predefined.

[0159] In some embodiments, where the first device is a terminal device and the second device is a network device, the higher-layer configuration parameters can be configured by the second device.

[0160] In some embodiments, where the first device is a first terminal device and the second device is a second terminal device, the higher-layer configuration parameters may be configured by a network device or a control node with management and control functions, such as a third device. In some embodiments, the third device may be a control node of the first terminal device or the second terminal device, such as the group head terminal of the terminal group to which the first terminal device belongs. In some cases, the third device and the second terminal device may be the same device. In other cases, the third device and the first terminal device may be the same device.

[0161] The following example illustrates how to determine the position of a specific piece of information included in the first request to be sent, for instance, the first piece of information within the first control information. In the case where the first request to be sent includes multiple pieces of information, the position of other pieces of information within the first control information can also be determined using at least one of the following methods.

[0162] Method I) The position of the first information in the first control information is determined based on high-level configuration parameters.

[0163] For example, the position of the first information within the first control information can be configured through high-level configuration parameters. This position can be the starting position of the first information within the first control information. For instance, this position could be the position of the first bit of the first information within the first control information.

[0164] In one example, taking the first request to send information including response resource indication information as an example, the starting position of the response resource indication information in the first control information is configured through high-level configuration parameters.

[0165] Method II) The position of the first information in the first control information is predefined.

[0166] For example, the position of the first information within the first control information can be predefined (i.e., specified through a protocol). This position could be the starting position of the first information within the first control information. For instance, this position could be the position of the first bit of the first information within the first control information.

[0167] In one example, taking the first request to send information including response resource indication information as an example, the starting position of the response resource indication information in the first control information is specified by the protocol.

[0168] In some embodiments, the first request to send information includes at least two pieces of information.

[0169] Method I) The position of each of the at least two pieces of information included in the first request sending information in the first control information is determined based on high-level configuration parameters.

[0170] In some embodiments, where the first device is a terminal device and the second device is a network device, the higher-layer configuration parameters can be configured by the second device.

[0171] In some embodiments, where the first device is a first terminal device and the second device is a second terminal device, the higher-layer configuration parameters may be configured by a network device or a control node with management and control functions, such as a third device. In some embodiments, the third device may be a control node for the first terminal device or the second terminal device, such as the group head terminal of the terminal group to which the first terminal device belongs. In some cases, the third device and the second terminal device may be the same device. In other cases, the third device and the first terminal device may be the same device.

[0172] In some embodiments, the position of each piece of information in the first request to send information within the first control information can be configured via higher-level configuration parameters. Furthermore, the starting position of each piece of information in the first request to send information within the first control information can be configured via higher-level configuration parameters. For example, this starting position is the position of the first bit of the information within the first control information.

[0173] In one example, taking the first request to send information including first indication information and response resource indication information as an example, the starting position of the first indication information and the starting position of the response resource indication information in the first control information are configured through high-level configuration parameters.

[0174] Method II) The position of each of the at least two pieces of information included in the first request sending information in the first control information is predefined.

[0175] For example, the position of each piece of information in the first request transmission information within the first control information can be predefined (i.e., specified through the protocol). This position could be the starting position of the information within the first control information; for example, it could be the position of the first bit of the information within the first control information.

[0176] In one example, taking the first request to send information including first indication information and response resource indication information as an example, the protocol specifies the starting position of the first indication information in the first control information, and the starting position of the response resource indication information in the first control information.

[0177] Method III) The position of a portion of the at least two pieces of information included in the first request sending information in the first control information is determined based on high-level configuration parameters, and the position of the other portion of the at least two pieces of information in the first control information is predefined.

[0178] In some embodiments, when the first request to send information includes at least two pieces of information, the position (e.g., starting position) of each piece of information in the first control information can be configured through high-level configuration parameters, and the position (e.g., starting position) of each piece of information in the first control information can be predefined (i.e., specified by the protocol).

[0179] In another alternative approach, when the first request to send information includes at least two pieces of information, the starting position of the first piece of information in the first control information is determined based on higher-level configuration parameters. The positions of the other pieces of information in the first control information are determined according to the starting position and predefined rules, including the sorting rules for the at least two pieces of information in the first control information. Further, the sorting rules for the at least two pieces of information in the first control information are: the at least two pieces of information are ordered consecutively in the first control information.

[0180] In some embodiments, the first of the at least two pieces of information is ranked first in the first control information.

[0181] (iii) Method for determining the number of bits occupied by the information included in the first request to be sent.

[0182] The number of bits corresponding to the information included in the first request to send in the first control information is determined based on higher-level configuration parameters; or, the number of bits corresponding to the information included in the first request to send in the first control information is predefined.

[0183] In some embodiments, where the first device is a terminal device and the second device is a network device, the higher-layer configuration parameters can be configured by the second device.

[0184] In some embodiments, where the first device is a first terminal device and the second device is a second terminal device, the higher-layer configuration parameters may be configured by a network device or a control node with management and control functions, such as a third device. In some embodiments, the third device may be a control node of the first terminal device or the second terminal device, such as the group head terminal of the terminal group to which the first terminal device belongs. In some cases, the third device and the second terminal device may be the same device. In other cases, the third device and the first terminal device may be the same device.

[0185] The following example illustrates how to determine the number of bits corresponding to a particular piece of information included in the first request to be sent, for instance, the first piece of information in the first control information. In the case where the first request to be sent includes multiple pieces of information, the number of bits corresponding to other pieces of information in the first control information can also be determined using at least one of the following methods.

[0186] Method I) The number of bits corresponding to the first information in the first control information is determined based on high-level configuration parameters.

[0187] For example, the number of bits corresponding to the first information in the first control information can be configured through high-level configuration parameters.

[0188] In one example, taking the first request to send information including response resource indication information as an example, the number of bits of the response resource indication information corresponding to the first control information is configured to be S bits through high-level configuration parameters, where S is a positive integer.

[0189] Method II) The number of bits corresponding to the first information in the first control information is predefined.

[0190] For example, the number of bits corresponding to the first information in the first control information can be predefined (i.e. specified by the protocol).

[0191] In one example, taking the first request to send information including response resource indication information as an example, the protocol specifies that the number of bits of the response resource indication information corresponding to the first control information is S bits, where S is a positive integer.

[0192] In some embodiments, the first request to send information includes at least two pieces of information.

[0193] Method I) The number of bits corresponding to each of the at least two pieces of information included in the first request sending information in the first control information is determined based on higher-level configuration parameters.

[0194] In some embodiments, where the first device is a terminal device and the second device is a network device, the higher-layer configuration parameters can be configured by the second device.

[0195] In some embodiments, where the first device is a first terminal device and the second device is a second terminal device, the higher-layer configuration parameters may be configured by a network device or a control node with management and control functions, such as a third device. In some embodiments, the third device may be a control node of the first terminal device or the second terminal device, such as the group head terminal of the terminal group to which the first terminal device belongs. In some cases, the third device and the second terminal device may be the same device. In other cases, the third device and the first terminal device may be the same device.

[0196] In some embodiments, the number of bits corresponding to each piece of information in the first request sending information in the first control information can be configured through high-level configuration parameters.

[0197] In one example, taking the first request to send information including first indication information and response resource indication information as an example, the number of bits corresponding to the first indication information in the first control information is configured as S1 bits and the number of bits corresponding to the response resource indication information in the first control information is configured as S2 bits through high-level configuration parameters, where S1 and S2 are positive integers.

[0198] Method II) The number of bits corresponding to each of the at least two pieces of information included in the first request sending information in the first control information is predefined.

[0199] For example, the number of bits corresponding to each piece of information in the first request to be sent can be predefined (i.e. specified by the protocol) in the first control information.

[0200] In one example, taking the first request to send information including first indication information and response resource indication information as an example, the protocol specifies that the number of bits corresponding to the first indication information in the first control information is S1 bits, and the number of bits corresponding to the response resource indication information in the first control information is S2 bits, where S1 and S2 are positive integers.

[0201] Method III) The number of bits corresponding to a portion of the at least two pieces of information included in the first request sending information in the first control information is determined based on higher-level configuration parameters, and the number of bits corresponding to the other portion of the at least two pieces of information in the first control information is predefined.

[0202] In some embodiments, when the first request to send information includes at least two pieces of information, the number of bits corresponding to each piece of information in the first control information can be configured through high-level configuration parameters, and the number of bits corresponding to each piece of information in the first control information can be predefined (i.e. specified by the protocol).

[0203] In one example, taking the first request to send information including first indication information and response resource indication information as an example, the number of bits corresponding to the first indication information in the first control information is configured as S1 bits by high-level configuration parameters, and the number of bits corresponding to the response resource indication information in the first control information is specified as S2 bits by the protocol, where S1 and S2 are positive integers.

[0204] In some embodiments, the number of bits corresponding to a piece of information in the first control information is related to the number of states corresponding to that information, or the number of bits corresponding to a piece of information in the first control information is determined based on the number of states corresponding to that information. In some embodiments, the number of states corresponding to a piece of information is determined based on higher-level configuration parameters or is predefined. As an example, assuming that a piece of information in the first request sending information is configured to correspond to M states through higher-level configuration parameters, or that the information is predefined to correspond to M states, where M is a positive integer, then the number of bits corresponding to that information in the first control information is ceil(log2(M)) bits, where log2 represents the logarithm to base 2, and ceil represents rounding up. For example, if M = 8, then the number of bits corresponding to that information in the first control information is 3 bits.

[0205] In some embodiments, configuring a certain information in the first request sending information, such as the number of bits corresponding to the first information in the first control information, through higher-level configuration parameters includes: configuring the first information to correspond to M states through higher-level configuration parameters, then the number of bits corresponding to the first information in the first control information is ceil(log2(M)).

[0206] The above technical solutions of the embodiments of this application are described with the example of the first device's request to send information including the first request to send information. It is not limited to this. In some embodiments, the first device's request to send information may also include one or more other request to send information. For example, the first device's request to send information also includes the second request to send information. The second request to send information is associated with the second cell, the second BWP, or the second frequency domain resource set. The second cell is the cell corresponding to the first device, the second BWP is the BWP corresponding to the second cell, and the second frequency domain resource set is the frequency domain resource set corresponding to the second BWP.

[0207] Regarding the second request to send information, how the information included in the second request to send information is determined, how the position of the information included in the second request to send information is determined, and how the number of bits occupied by the information included in the second request to send information is determined, can all be referred to the aforementioned description of the first request to send information.

[0208] It should be noted that the method used to determine the second request to send information can be the same as that used to determine the first request to send information, or the method used to determine the second request to send information can be different from that used to determine the first request to send information. For example: the information included in the first request to send information is determined based on higher-level configuration parameters, while the information included in the second request to send information is predefined. For example: the position of each piece of information included in the first request to send information in the first control information is predefined, while the position of each piece of information included in the second request to send information in the first control information is determined based on higher-level configuration parameters. For example: the number of bits corresponding to each piece of information included in the first request to send information in the first control information is determined based on higher-level configuration parameters, and the number of bits corresponding to each piece of information included in the second request to send information in the first control information is determined based on higher-level configuration parameters.

[0209] In some embodiments, the information included in the first request sending information and the second request sending information may be the same or different.

[0210] It should be noted that if both the first request to send information and the second request to send information include a certain information, the number of bits corresponding to that information in the first request to send information and the number of bits corresponding to that information in the second request to send information may be the same or different.

[0211] The format of the first control information is explained below with specific application examples.

[0212] Application Example 1

[0213] Assume the first request to send information includes two pieces of information, information A and information B. The network device configures information A to start at bit L1 in the first control information using a first higher-layer configuration parameter, where information A corresponds to bit S1 in the first control information. The network device configures information B to start at bit L2 in the first control information using a second higher-layer configuration parameter, where information B corresponds to bit S2 in the first control information. Figure 4-1 As shown. After receiving the first control information, the first device reads bit S1 starting from bit L1 in the first control information and determines that bit S1 corresponds to information A; it then reads bit S2 starting from bit L2 in the first control information and determines that bit S2 corresponds to information B.

[0214] Application Example 2

[0215] Assume the first request to send information includes two pieces of information, information A and information B. The ordering rule for information A and information B in the first control information is predefined; for example, information A and information B are ordered consecutively in the first control information, with information A preceding information B. The network device configures information A to start at bit L1 in the first control information via higher-layer configuration parameters, where information A corresponds to bit S1; and information B to start after the end of information A in the first control information, where information B corresponds to bit S2, such as... Figure 4-2 As shown. After receiving the first control information, the first device reads bit S1 starting from bit L1 in the first control information and determines that bit S1 corresponds to information A; it then reads bit S2 starting from the next bit after bit S1 and determines that bit S2 corresponds to information B.

[0216] Application Example 3

The first request transmission information is associated with a first cell, a first BWP, or a first frequency domain resource set, and the second request transmission information is associated with a second cell, a second BWP, or a second frequency domain resource set. The first request transmission information includes two pieces of information, information A and information B. The second request transmission information includes two pieces of information, information C and information D. The network device configures information A in the first control information by starting at bit L1, where information A corresponds to S1 bits; the network device configures information B in the first control information by starting at bit L2, where information B corresponds to S2 bits; the network device configures information C in the first control information by starting at bit L3, where information C corresponds to S3 bits; and the network device configures information D in the first control information by starting at bit L4, where information D corresponds to S4 bits. Figure 4-3 As shown. After receiving the first control information, the first device reads bit S1 starting from bit L1 of the first control information and determines that bit S1 corresponds to information A; it reads bit S2 starting from bit L2 of the first control information and determines that bit S2 corresponds to information B; it reads bit S3 starting from bit L3 of the first control information and determines that bit S3 corresponds to information C; it reads bit S4 starting from bit L4 of the first control information and determines that bit S4 corresponds to information D.

[0218] Application Example 4

[0219] Assume that the request to send information from the first device includes a first request to send information and a second request to send information. The first request to send information is associated with a first cell, a first BWP, or a first frequency domain resource set, and the second request to send information is associated with a second cell, a second BWP, or a second frequency domain resource set. The first request to send information includes two pieces of information, information A and information B. The ordering rule for information A and information B in the first control information is predefined; for example, information A and information B are ordered consecutively in the first control information, and information A precedes information B. The second request to send information includes two pieces of information, information C and information D. The ordering rule for information C and information D in the first control information is predefined; for example, information C and information D are ordered consecutively in the first control information, and information C precedes information D. The network device configures information A to start at bit L1 in the first control information using first higher-layer configuration parameters, where information A corresponds to S1 bits; and information B to start after the end of information A in the first control information, where information B corresponds to S2 bits. The network device configures information C via a third higher-layer configuration parameter, starting at bit L3 in the first control information, where information C corresponds to S3 bits; information D starts after the end of information C in the first control information format, where information D corresponds to S4 bits, as shown below. Figure 4-4 As shown. After receiving the first control information, the first device reads bit S1 starting from bit L1 of the first control information and determines that bit S1 corresponds to information A; it reads bit S2 starting from the next bit after bit S1 and determines that bit S2 corresponds to information B; it reads bit S3 starting from bit L3 of the first control information and determines that bit S3 corresponds to information C; it reads bit S4 starting from the next bit after bit S3 and determines that bit S4 corresponds to information D.

[0220] The following describes the various pieces of information included in the request transmission information of the first device in the above scheme. It should be noted that the information included in the first request transmission information in the above scheme can also refer to all or part of the relevant descriptions below.

[0221] ●The request to send information from the first device includes first instruction information.

[0222] In some embodiments, the first indication information is used to indicate to the first device a request for transmission; or, the first indication information is used to indicate to the first device not to request transmission; or, the first indication information is used to indicate to a first group a request for transmission; or, the first indication information is used to indicate to the first group not to request transmission; wherein, the first device corresponds to the first group, and the first group is a device group or a cell group.

[0223] For example, the first indication information is represented by 1 bit. The 1 bit has a first value, indicating that the first indication information is used to indicate to the first device a request for transmission; the 1 bit has a second value, indicating that the first indication information is used to indicate to the first device that transmission is not requested. Here, the first value is, for example, 1, and the second value is, for example, 0; or, the first value is, for example, 0, and the second value is, for example, 1.

[0224] For example, the first indication information is represented by 1 bit. The 1 bit has a first value, indicating that the first indication information is used to request transmission to the first group of indications; the 1 bit has a second value, indicating that the first indication information is used to request no transmission to the first group of indications. Here, the first value is, for example, 1, and the second value is, for example, 0; or, the first value is, for example, 0, and the second value is, for example, 1.

[0225] In some embodiments, the first group in the above scheme is a device group, which includes at least one device, and the first device belongs to the device group. The first indication information is used to indicate a request for transmission to all devices in the device group to which the first device belongs, or the first indication information is used to indicate to all devices in the device group to which the first device belongs that no transmission is requested.

[0226] In some embodiments, the first group in the above scheme is a cell group, which includes at least one cell. The at least one cell is all or some of the cells configured on the first device. For example, the first device is configured with four cells, two of which are assigned to cell group 1, and the other two to cell group 2. The first group is cell group 1. The first indication information is used to indicate to cell group 1 that a transmission request is needed, or the first indication information is used to indicate to cell group 1 that a transmission request is not needed. It should be noted that the first indication information indicating a transmission request to the cell group can be understood as indicating to the first device that a transmission request is needed on all cells in the cell group. The first indication information indicating a transmission request is also understood as indicating to the first device that a transmission request is not needed on all cells in the cell group.

[0227] In some embodiments, the first indication information is associated with a first cell, a first BWP, or a first frequency domain resource set. The first indication information is used to instruct the first device to request transmission on the first cell, the first BWP, or the first frequency domain resource set; or, the first indication information is used to instruct the first device not to request transmission on the first cell, the first BWP, or the first frequency domain resource set; or, the first indication information is used to instruct a first group to request transmission on the first cell, the first BWP, or the first frequency domain resource set; or, the first indication information is used to instruct the first group not to request transmission on the first cell, the first BWP, or the first frequency domain resource set; wherein the first device corresponds to the first group, and the first group is a device group.

[0228] In some embodiments, the first indication information may be transmitted via the first cell, the first BWP, or the first frequency domain resource set; or, the first control information may be transmitted via the first cell, the first BWP, or the first frequency domain resource set.

[0229] In other embodiments, the first indication information may not be transmitted through the first cell, the first BWP, or the first frequency domain resource set; or, the first control information may not be transmitted through the first cell, the first BWP, or the first frequency domain resource set.

[0230] For example, the first indication information is represented by 1 bit. The 1 bit can have a first value, indicating that the first indication information is used to instruct the first device to request transmission on the first cell, the first BWP, or the first frequency domain resource set; or the 1 bit can have a second value, indicating that the first indication information is used to instruct the first device not to request transmission on the first cell, the first BWP, or the first frequency domain resource set. Here, the first value is, for example, 1, and the second value is, for example, 0; or, the first value is, for example, 0, and the second value is, for example, 1.

[0231] For example, the first indication information is represented by 1 bit. The 1 bit can have a first value, indicating that the first indication information is used to request transmission on the first cell, the first BWP, or the first frequency domain resource set; or the 1 bit can have a second value, indicating that the first indication information is used to not request transmission on the first cell, the first BWP, or the first frequency domain resource set. Here, the first value is, for example, 1, and the second value is, for example, 0; or, the first value is, for example, 0, and the second value is, for example, 1.

[0232] In some embodiments, the first group in the above scheme is a device group, which includes at least one device, and the first device belongs to the device group. The first indication information is used to instruct all devices in the device group to which the first device belongs to request transmission on the first cell, the first BWP, or the first frequency domain resource set; or, the first indication information is used to instruct all devices in the device group to which the first device belongs to not request transmission on the first cell, the first BWP, or the first frequency domain resource set.

[0233] In this embodiment of the application, the first indication information can be implemented in the following ways:

[0234] Method 1) The first indication information is a dedicated information field in the first control information.

[0235] Here, the first indication information is a dedicated information field in the first control information, which can be understood as the first indication information occupying a separate information field (or a dedicated information field) in the first control information. For example, the first indication information occupies 1 bit of information field in the first control information.

[0236] Method 2) The first indication information is characterized by a first information status corresponding to at least one piece of information included in the request to send information of the first device, and the first information status is used to determine that no transmission is requested.

[0237] Here, the first indication information does not have an independent information field in the first control information. The first indication information can be represented by the first information status of at least one of the information in the request to send information of the first device. If at least one of the information in the request to send information of the first device has a first information status, it indicates that no transmission is requested; if at least one of the information in the request to send information of the first device does not have a first information status, it indicates that transmission is requested, and the first device interprets the information status of the at least one information in a normal manner.

[0238] For example, the request transmission information of the first device includes response resource indication information, which is characterized by the information status corresponding to the response resource indication information. If the response resource indication information indicates an invalid response resource, for example, if it does not indicate the time domain location of the response resource, it means that the second device has not requested transmission from the first device; or, if the response resource indication information indicates a valid response resource, it means that the information domain is interpreted according to the response resource indication information, and the second device initiates the request transmission to the first device. The response resource used in the response process is determined based on the valid response resource indicated by the response resource indication information.

[0239] Method 3) The first indication information is characterized by a second information state corresponding to some or all of the bits in the request to send information of the first device, and the second information state is used to determine that no transmission is requested.

[0240] Here, the first indication information does not have an independent information field in the first control information. The first indication information can be represented by the second information status of some or all of the bits included in the request to send information of the first device. If some or all of the bits included in the request to send information of the first device have the second information status, it indicates that no transmission is requested; if some or all of the bits included in the request to send information of the first device do not have the second information status, it indicates that transmission is requested, and the first device interprets the request to send information of the first device in a normal manner.

[0241] For example, the request to send information from the first device includes M bits, where M is a positive integer. If all M bits are "1" or all M bits are "0", it indicates that no transmission is requested; otherwise, it indicates that transmission is requested, and the first device interprets the M bits normally.

[0242] ●The request to send information from the first device includes beam indication information.

[0243] The beam indication information is used to determine at least one of the following: first beam information associated with the first control information, second beam information associated with physical channel transmission, and third beam information associated with the response information, wherein the physical channel includes the physical channel associated with the request transmission information of the first device. For example, the beam indication information is used to determine at least one of the following: first reference signal information associated with the first control information, second reference signal information associated with physical channel transmission, and third reference signal information associated with the response information.

[0244] (I) First Beam Information

[0245] In some embodiments, the first beam information associated with the first control information may be beam information used to transmit the first control information, or beam information used to determine the transmission beam of the first control information. Alternatively, the first beam information associated with the first control information may be information of a first reference signal having a quasi-co-located QCL relationship with the first control information or the physical channel or physical signal carrying the first control information, such as the index of the first reference signal or the first TCI information.

[0246] In some embodiments, the first beam information includes Transmission Configuration Indication (TCI) indication information associated with the first control information and / or reference signal information associated with the first control information.

[0247] Furthermore, in some embodiments, the reference signal information associated with the first control information includes a reference signal index associated with the first control information. Here, the reference signal index is, for example, a Synchronizing Signal / PBCH Block (SSB) index or a Channel State Information-Reference Signal (CSI-RS) index.

[0248] In one scenario, if the network device is configured with a first beam information set that includes multiple beam information items, the beam indication information is used to indicate the first beam information from the first beam information set. In another scenario, if the network device is configured with a first beam information set that includes one beam information item, the first device uses the configured beam information as the first beam information; in this case, the beam indication information is not used to determine the first beam information.

[0249] (II) Second Beam Information

[0250] In some embodiments, the second beam information associated with the physical channel can be beam information used to transmit the physical channel. For example, the beam used to transmit the physical channel can be determined based on the second beam information associated with the physical channel. Alternatively, the second beam information associated with the physical channel can be information about a second reference signal that has a QCL relationship with the physical channel, such as the index of the second reference signal or second TCI information.

[0251] In some embodiments, the physical channel may be the physical channel corresponding to the request sending information of the first device. For example, the physical channel transmitted after the request sending information and response information have been exchanged.

[0252] In other embodiments, the second beam information is beam information used to transmit physical signals. The physical signals can be physical signals corresponding to the request to send information from the first device, such as physical signals transmitted after the request to send information and response information have been exchanged.

[0253] In some embodiments, the second beam information includes TCI indication information associated with the physical channel transmission and / or reference signal information associated with the physical channel transmission, wherein the physical channel includes the physical channel associated with the request transmission information of the first device. For example, the physical channel includes the physical channel for the request transmission information of the first device to request transmission.

[0254] Furthermore, in some embodiments, the physical channel transmission associated reference signal information includes a physical channel transmission associated reference signal index. Here, the reference signal index is, for example, an SSB index or a CSI-RS index.

[0255] Furthermore, in some embodiments, when the first device is a terminal device and the second device is a network device, the physical channel is a Physical Downlink Shared Channel (PDSCH). Here, in some embodiments, the PDSCH includes a scheduled PDSCH and / or an SPS PDSCH. The physical signal may include CSI-RS or SRS. When the first device is a first terminal device and the second device is a second terminal device, the physical channel is a Physical Sidelink Shared Channel (PSSCH). The physical signal may include a reference signal on the sidelink.

[0256] In one scenario, if the network device is configured with a second beam information set that includes multiple beam information items, the beam indication information is used to indicate the second beam information from the second beam information set. In another scenario, if the network device is configured with a second beam information set that includes one beam information item, the first device uses the configured beam information as the second beam information; in this case, the beam indication information is not used to determine the second beam information.

[0257] (III) Third Beam Information

[0258] In some embodiments, the third beam information includes reference signal information associated with the response information.

[0259] Furthermore, in some embodiments, the reference signal information associated with the response information includes a reference signal index associated with the response information. Here, the reference signal index is, for example, a Sounding Reference Signal (SRS) index.

[0260] In one scenario, if the network device is configured with a third beam information set that includes multiple beam information items, the beam indication information is used to indicate the third beam information from the third beam information set. In another scenario, if the network device is configured with a third beam information set that includes one beam information item, the first device uses the configured beam information as the third beam information; in this case, the beam indication information is not used to determine the third beam information.

[0261] In this embodiment, the third beam information is used by the first device to determine the beam used during the channel access process, and / or the third beam information is used to determine the beam used by the first device to send the response information. Here, the channel access process includes the channel access process corresponding to the first device sending the response information.

[0262] It should be noted that the beam used in the channel access process can be understood as the beam used for channel detection (LBT) before sending the response information, and the corresponding channel access method is directional channel access method (i.e., directional LBT).

[0263] (iv) In some embodiments, the beam indication information further includes second indication information and / or third indication information.

[0264] In the above scheme, the second indication information is used to indicate that the third beam information is associated with the first beam information, or that the third beam information is associated with the second beam information. Alternatively, the second indication information is used to indicate that the channel access procedure corresponding to the response information is associated with the first beam information, or that the channel access procedure corresponding to the response information is associated with the second beam information.

[0265] In some embodiments of this application, the second indication information is used to indicate that the channel access procedure corresponding to the response information is associated with the first beam information or the second beam information, or the second indication information is used to indicate that the channel access procedure corresponding to the response information is associated with the third beam information. In some embodiments, when the second indication information indicates that the channel access procedure corresponding to the response information is associated with the first beam information or the second beam information, whether the channel access procedure corresponding to the response information is associated with the first beam information or the second beam information is determined based on higher-layer parameters.

[0266] For example, the second indication information is represented by 1 bit. The value of this 1 bit is a first value, indicating that the second indication information is used to indicate that the third beam information is associated with the first beam information; the value of this 1 bit is a second value, indicating that the second indication information is used to indicate that the third beam information is associated with the second beam information. Here, the first value is, for example, 1, and the second value is, for example, 0; or, the first value is, for example, 0, and the second value is, for example, 1.

[0267] It should be noted that the association between the third beam information and the first beam information can be understood as a correspondence between the third beam information and the first beam information, and the third beam information can be determined through the first beam information. Similarly, the association between the third beam information and the second beam information can be understood as a correspondence between the third beam information and the second beam information, and the third beam information can be determined through the second beam information.

[0268] In some embodiments, the first device completes the channel access procedure corresponding to the response information based on at least one of first beam information, second beam information, third beam information, and second indication information. For example, if the second indication information indicates that the third beam information is associated with the first beam information, then the first device determines the beam used in the channel access procedure corresponding to the response information based on the first beam information; or, if the second indication information indicates that the third beam information is associated with the second beam information, then the first device determines the beam used in the channel access procedure corresponding to the response information based on the second beam information.

[0269] In some embodiments, the third indication information is used to indicate at least one of the following: the first beam information is beam information specific to the first device or common beam information; the second beam information is beam information specific to the first device or common beam information; and the third beam information is beam information specific to the first device or common beam information.

[0270] In some embodiments, beam information may be replaced with reference signal information, reference signal index, or TCI information.

[0271] For example, the third indication information is represented by 1 bit. The 1 bit can have a first value, indicating that at least one of the first, second, and third beam information is beam information specific to the first device; or a second value, indicating that at least one of the first, second, and third beam information is common beam information. Here, the first value is, for example, 1, and the second value is, for example, 0; or, the first value is, for example, 0, and the second value is, for example, 1.

[0272] In some embodiments, TCI indication information can be used to indicate a quasi-co-located (QCL) reference signal corresponding to a downlink signal or downlink channel, so that the receiver can receive the downlink signal or downlink channel based on the QCL reference signal.

[0273] In some embodiments, the TCI indication information is used to indicate at least one of the following:

[0274] TCI Status ID is used to identify a TCI status;

[0275] QCL Information 1;

[0276] QCL information 2.

[0277] One QCL message contains the following information:

[0278] The QCL type configuration can be one of QCL type A, QCL type B, QCL type C, or QCL type D;

[0279] QCL reference signal configuration includes the cell ID where the reference signal is located, the BWP ID, and the identifier of the reference signal (which can be a CSI-RS resource ID or an SSB index).

[0280] Among them, at least one of QCL information 1 and QCL information 2 must have a QCL type of one of type A, type B, and type C, and the other QCL information (if configured) must have a QCL type of D.

[0281] The definitions of different QCL type configurations are as follows:

[0282] 'QCL-TypeA': {Doppler shift, Doppler spread, average delay, delay spread};

[0283] 'QCL-TypeB': {Doppler shift, Doppler spread};

[0284] 'QCL-TypeC': {Doppler shift, average delay};

[0285] 'QCL-TypeD':{Spatial Rx parameter}.

[0286] ●The request information sent by the first device includes response resource indication information.

[0287] The response resource indication information is used to determine at least one of the following: resource information, which is used to determine the response resource for transmitting the response information; time-domain location information, which is used to determine the time-domain location of the response resource; downlink allocation indication information, which is used to determine the location of the response information in the feedback codebook; and power control information, which is used to determine the transmit power for transmitting the response information.

[0288] (i) In some embodiments, the response resources include Physical Uplink Control Channel (PUCCH) resources.

[0289] The resource information includes PUCCH resource indication information (e.g., PUCCH resource indicator). Here, the PUCCH resource indication information is used to indicate a PUCCH resource, which is used to transmit response information.

[0290] The time-domain location information includes Hybrid Automatic Repeat reQuest (HARQ) feedback timing indication information (e.g., PDSCH-to-HARQ_feedback timing indicator). Here, the HARQ feedback timing indication information is used to dynamically indicate the time-domain location of the HARQ feedback resource, such as the time slot of the HARQ feedback resource, which is usually represented by K1.

[0291] In some embodiments, HARQ feedback timing indication information is used to indicate the values ​​in the HARQ feedback timing set. The HARQ feedback timing set may be preset or configured by the network device, and the HARQ feedback timing set includes at least one K1 value.

[0292] In one scenario, if the HARQ feedback timing set includes only one K1 value, the request transmission information of the first device may not include the HARQ feedback timing indication information, and the temporal location of the HARQ feedback resource is determined based on the K1 value in the HARQ feedback timing set.

[0293] In another scenario, if the HARQ feedback timing set includes multiple K1 values, these K1 values ​​can be preset or configured by the network device. Assume the multiple K1 values ​​are {1, 2, 3, 4, 5, 6, 7, 8}. The HARQ feedback timing indication information is represented by 3 bits, with each of the eight possible values ​​corresponding to one of the eight K1 values. A single value of these 3 bits indicates a K1 value within the HARQ feedback timing set, and the temporal location of the HARQ feedback resource is determined based on this K1 value. For example, a 3-bit value of 000 indicates K1 = 1; a 3-bit value of 001 indicates K1 = 2, and so on.

[0294] In another scenario, if the HARQ feedback timing set includes multiple K1 values ​​(which can be preset or configured by the network device), assuming the HARQ feedback timing set includes four K1 values, the HARQ feedback timing indication information is represented by 2 bits. These 2 bits have four possible values, each corresponding one-to-one with one of the four K1 values. A single 2-bit value indicates one K1 value in the HARQ feedback timing set, and the temporal location of the HARQ feedback resource is determined based on this K1 value. For example, a 2-bit value of 00 indicates the first K1 value in the HARQ feedback timing set. Similarly, a 2-bit value of 01 indicates the second K1 value, and so on.

[0295] (ii) In some embodiments, the response resources include Physical Random Access Channel (PRACH) resources.

[0296] The resource information includes PRACH resource indication information. Here, in some embodiments, the PRACH resource indication information includes a random access preamble sequence index.

[0297] The time-domain location information includes the random access channel transmission opportunities corresponding to the PRACH resource.

[0298] (iii) In some embodiments, the response resources include SRS resources.

[0299] The resource information includes SRS resource indication information. For example, the time-domain location information, and / or frequency-domain location information, and / or SRS index information of the SRS resource. The time-domain location information of the SRS resource includes the number of symbols included in the corresponding time slot.

[0300] The time-domain location information includes the time unit information corresponding to the SRS resource. Here, in some embodiments, the time unit may be a time slot, a symbol, etc.

[0301] (iv) In some embodiments, the response resources include a Physical Sidelink Feedback Channel (PSFCH).

[0302] The resource information includes PSFCH resource indication information, such as the time-domain location information and / or frequency-domain location information of the PSFCH resource.

[0303] The time-domain location information includes HARQ feedback timing indication information.

[0304] ●The request to send information by the first device includes channel access indication information.

[0305] The channel access indication information is used to determine at least one of the following: the channel access method corresponding to the response information; and the length of the cyclic prefix extension (CPE) corresponding to the response information.

[0306] In some embodiments, the CPE length corresponding to the response information is the length of the extended CP of the first symbol of the response information.

[0307] In some embodiments, the channel access method corresponding to the response information is one of the following: channel access without channel detection, a first type of channel access, or a second type of channel access.

[0308] In some embodiments, the first type of channel access is a channel access method that randomly backs up multiple listening time slots.

[0309] In some embodiments, the second type of channel access is a channel access method with a fixed listening time slot length.

[0310] In some embodiments, the first type of channel access may include a first type of channel access corresponding to directional channel detection or a first type of channel access corresponding to omnidirectional channel detection.

[0311] In some embodiments, the second type of channel access may include a second type of channel access corresponding to directional channel detection or a second type of channel access corresponding to omnidirectional channel detection.

[0312] In other words, the channel access method corresponding to the response information can be one of the following:

[0313] Channel access without channel detection, channel access of type 1 corresponding to directional channel detection, channel access of type 2 corresponding to directional channel detection, channel access of type 1 corresponding to omnidirectional channel detection, and channel access of type 2 corresponding to omnidirectional channel detection.

[0314] In some embodiments, the channel access indication information includes indication information for indicating the channel access method and / or indication information for indicating the CPE length.

[0315] In some embodiments, the channel access indication information includes indication information for indicating the channel access method and / or indication information for indicating the CPE length; or, the channel access indication information is used to indicate the jointly encoded channel access method and the CPE length.

[0316] In some embodiments, the channel access method and the CPE length can be indicated by different information, or they can be indicated by the same information.

[0317] For example, the channel access indication information is used to indicate a first channel access indication information, which corresponds to a set of configurations in a first configuration set. Each set of configurations in the first configuration set includes a channel access method and / or an extended cyclic prefix (CPE) length.

[0318] In some embodiments, the first configuration set includes a set of configurations that indicate the channel access method as channel access without channel detection and / or the CPE length as 0.

[0319] For example, the channel access indication information is used to indicate a first channel access indication information and a second channel access indication information, wherein the first channel access indication information is used to indicate one of at least one channel access method, and the second channel access indication information is used to indicate one of at least one CPE length.

[0320] In some embodiments, the channel detection beam type corresponding to the channel access method includes omnidirectional channel detection or directional channel detection. In some embodiments, the channel detection beam type can be omnidirectional or directional. In the directional case, the channel detection beam direction can be a specific associated beam direction or a reference signal index or Transmission Configuration Indicator (TCI) information.

[0321] In some embodiments, the channel detection beam type corresponding to the channel access method determined according to the channel access indication information is determined based on higher-layer parameters configured by the network device, indicated by the channel access indication information, or preset; and / or, the channel detection beam direction (i.e., the beam used during channel access) is determined based on higher-layer parameters configured by the network device, indicated by the channel access indication information, or preset.

[0322] In some embodiments, the physical channel corresponding to the request transmission information of the first device includes a first PDSCH, and the channel access method determined according to the channel access indication information is also used to transmit HARQ-ACK information corresponding to the first PDSCH.

[0323] In other embodiments, the physical channel corresponding to the request sending information of the first device includes a first PUSCH, and the channel access method is also used to transmit the first PUSCH.

[0324] In some embodiments, if the channel access method corresponding to the HARQ-ACK information corresponding to the first PDSCH is the channel access method corresponding to directional channel detection, then the beam used in the channel access process corresponding to the HARQ-ACK information corresponding to the first PDSCH is the same as the beam used in the channel access process corresponding to the acknowledgment information; or, the beam used in the channel access process corresponding to the HARQ-ACK information corresponding to the first PDSCH is determined according to the beam indication information.

[0325] In other embodiments, if the channel access method corresponding to the first PUSCH is channel access with directional channel detection, then the beam used in the channel access process corresponding to the first PUSCH is the same as the beam used in the channel access process corresponding to the response information; or, the beam used in the channel access process corresponding to the first PUSCH is determined according to the beam indication information.

[0326] ●The request information sent by the first device includes the length information of the COT and / or the end position information of the COT.

[0327] (i) In some embodiments, the length information of the COT refers to the number of time units included in the COT from the time unit in which the second device sends the first control information or the number of time units included in the COT from the time unit in which the first device receives the first control information.

[0328] In some embodiments of the above scheme, the length information of COT can refer to the number of remaining time units within COT. Here, the remaining time units refer to unoccupied time units.

[0329] (ii) In some embodiments, the end position information of the COT refers to the time unit corresponding to the end position of the COT.

[0330] In the above scheme, the time unit can be a subframe, a time slot, a sub-slot, or a symbol, etc.

[0331] For example, the length information of COT can be represented by the number of time slots or symbols.

[0332] For example, the end position information of COT is indicated by the number of the last time slot or symbol occupied by COT.

[0333] ●The request information sent by the first device includes frequency domain resource set indication information.

[0334] The frequency domain resource set indication information is used to determine the association between the request transmission information of the first device and at least one frequency domain resource set of the first device; and / or, the frequency domain resource set indication information is used to determine whether at least one frequency domain resource set can be used for transmission.

[0335] Here, the first device corresponds to at least one frequency domain resource set. For example, the P cells of the first device correspond to P frequency domain resource sets, where each cell corresponds one-to-one with a frequency domain resource set; or the first cell of the first device corresponds to P frequency domain resource sets; or the first BWP on the first cell of the first device corresponds to P frequency domain resource sets, where P is a positive integer. In some cases, the second device can perform channel detection on the P frequency domain resource sets and transmit using the frequency domain resource sets that have successfully undergone channel detection. That is, the frequency domain resource sets actually used by the second device for signal transmission are determined based on the channel detection results. Therefore, the second device can indicate to the first device whether the P frequency domain resource sets can be used for downlink reception, sidelink reception, or uplink transmission.

[0336] In some embodiments, the frequency domain resource set indication information is represented by P bits, where each bit in the P bits corresponds to a frequency domain resource set, and the P bits correspond one-to-one with the P frequency domain resource sets. The value of each bit is used to indicate whether the frequency domain resource set corresponding to that bit is available for transmission, and / or to indicate whether a transmission request is made on the frequency domain resource set corresponding to that bit.

[0337] In some embodiments, the bit in the frequency domain resource set indication information corresponding to the first frequency domain resource set is used to indicate to the first device that a transmission is requested on the first frequency domain resource set; or, the bit in the frequency domain resource set indication information corresponding to the first frequency domain resource set is used to indicate to the first device that a transmission is not requested on the first frequency domain resource set; or, the bit in the frequency domain resource set indication information corresponding to the first frequency domain resource set is used to indicate to the first group that a transmission is requested on the first frequency domain resource set; or, the bit in the frequency domain resource set indication information corresponding to the first frequency domain resource set is used to indicate to the first group that a transmission is not requested on the first frequency domain resource set; wherein, the first device corresponds to the first group, and the first group is a device group.

[0338] For example, the frequency domain resource set indication information is represented by 3 bits, with each of the 3 bits corresponding one-to-one with one of the 3 frequency domain resource sets. Taking one of the 3 bits as an example, this bit corresponds to the first frequency domain resource set. In one case, the value of this bit is a first value, used to indicate to the first device that a transmission is requested on the first frequency domain resource set; the value of this bit is a second value, used to indicate to the first device that a transmission is not requested on the first frequency domain resource set. In another case, the value of this bit is a first value, used to indicate to the device group (i.e., the first group) to which the first device belongs that a transmission is requested on the first frequency domain resource set; the value of this bit is a second value, used to indicate to the device group (i.e., the first group) to which the first device belongs that a transmission is not requested on the first frequency domain resource set. Here, the first value is, for example, 1, and the second value is, for example, 0; or, the first value is, for example, 0, and the second value is, for example, 1.

[0339] It should be noted that the equipment group in the above scheme includes at least one device, and the first device belongs to the equipment group.

[0340] ● The request to send information from the first device includes slot format indicator (SFI).

[0341] The time slot format indication information is used to indicate the time slot format, which is used to determine the symbol type of each symbol among the multiple symbols included in a time slot. Here, the symbol type can be a downlink symbol, a flexible symbol, or an uplink symbol.

[0342] ●The request information sent by the first device includes control channel monitoring set group indication information.

[0343] The control channel monitoring set group indication information is used by the first device to determine the control channel set group to be monitored.

[0344] For example, the control channel monitoring set group indication information is represented by 1 bit. If the value of this 1 bit is a first value, then the control channel monitoring set group indication information is used to indicate that the first device is monitoring control channel monitoring set group 0; if the value of this 1 bit is a second value, then the control channel monitoring set group indication information is used to indicate that the first device is monitoring control channel monitoring set group 1. Here, the first value is, for example, 1, and the second value is, for example, 0; or, the first value is, for example, 0, and the second value is, for example, 1.

[0345] In this embodiment of the application, after the first device determines the request to send information of the first device according to the first control information, it determines whether the second device requests transmission according to the request to send information of the first device.

[0346] 1) If the second device requests transmission, the first device determines to send a first response message to the second device; or,

[0347] 2) If the second device does not request transmission, the first device determines to send a second response message to the second device or not to send a response message; or,

[0348] 3) If the first device determines to allow transmission when the second device requests transmission, then the first device determines to send a first response message to the second device; or,

[0349] 4) If the first device determines that transmission is not allowed when the second device requests transmission, the first device determines to send the second response information to the second device or not to send the response information.

[0350] In the above scheme, the first response information indicates that transmission is allowed, and the second response information indicates that transmission is not allowed. In some embodiments, the first response information is an acknowledgment (ACK) message, and the second response information is a negative acknowledgment (NACK) message.

[0351] In some embodiments, if the first device determines to send the response information (which may be a first response information or a second response information) to the second device, and the channel access corresponding to the response information is successful, the first device sends the response information to the second device; if the channel access corresponding to the response information fails, the first device does not send the response information to the second device.

[0352] For the second device, if it receives the first response information, it determines that it can wirelessly communicate with the first device, such as performing downlink or sidelink transmission. If the second device receives the second response information or does not receive any response information, it determines that it will not wirelessly communicate with the first device, such as performing downlink or sidelink transmission.

[0353] In some embodiments, when channel detection is required for transmission from the second device to the first device, the second device needs to perform channel detection before transmission. If the channel detection is successful, it can perform wireless communication with the first device, such as downlink transmission or sidelink transmission.

[0354] In some embodiments, the channel access method corresponding to the second device sending the first control information to the first device is determined based on higher-layer configuration parameters and / or predefined.

[0355] The technical solution of this application embodiment designs a format for first control information, which can be used for information exchange during the channel access process corresponding to the receiver-assisted channel access method. The first control information in this application can be sent through a common control channel. This first control information may include request transmission information from multiple devices. After a first device obtains its own request transmission information from the first control information, it can determine, based on the request transmission information, whether a second device requests transmission, resource information of the response information, beam information corresponding to the response information, and other relevant information, thereby completing the information exchange between the second device and the second device.
