For example, the communication system 100 used in the embodiment of the present application is shown in FIG. 1. The communication system 100 may include a network device 110, and the network device 110 may be a device that communicates with a terminal device 120 (or called a communication terminal, a terminal). Network device 110 may provide communication coverage for a particular geographic area and may communicate with terminal devices located within the coverage area. Optionally, network device 110 may be a Base Transceiver Station (BTS) in a GSM or CDMA system, or may be a NodeB (NB) in a WCDMA system, or an evolutionary NodeB (eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network ( CRAN), or the network device can be a mobile switching center, a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, a network-side device in a 5G network, a network device in a future evolutionary public land mobile network (PLMN) or the like.

Communication system 100 further comprises at least one terminal device 120 located within the coverage area of network device 110. The term "terminal device" as used herein includes, but is not limited to, user equipment (UE), access terminal, user unit , user station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The access terminal may be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless user access station (WLL), a personal digital assistant (PDA), a wireless capable portable device, a computing device, or other data processing devices, connected to wireless modems, devices in a vehicle, wearable devices, terminal devices in the future 5G network or terminal devices in the future Public Enhanced Land Mobile Network (PLMN) or the like, which is not a limitation in embodiments of the present invention.

Optionally, direct communication between terminals (device-to-device, D2D communication) can take place between terminal devices 120.

Optionally, a 5G system or 5G network may also be referred to as a New Radio (NR) system or NR network.

In FIG. 1 shows one network device and two terminal devices as an example. Optionally, communication system 100 may include multiple network devices, and each network device's coverage area may contain a different number of terminal devices. The embodiments of the present application do not limit this.

Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not a limitation in the embodiments of the present application.

It should be understood that a device having a communication function in a network/system in this embodiment of the present application may be referred to as a communication device. Using the communication system 100 shown in FIG. 1, as an example, the communication device may include a network device 110 and a terminal device 120 that have a communication function. Network device 110 and terminal device 120 may be the specific devices described above and will not be described again here; the communication device may also include other devices in the communication system 100 such as a network controller, mobility management entities, and other network entities. This is not limited to the embodiments of this application.

It should be understood that the terms "system" and "network" in this application are usually used interchangeably in the present description. In the present description, the term "and/or" is only a relationship describing related objects, and indicates that there can be three types of relationships. For example, A and/or B can represent the following three states: only A exists, both A and B exist, and only B exists. related objects.

On the unlicensed spectrum, a communication device (such as a network device) must perform listen-before-talk (LBT) detection on channels on the unlicensed spectrum prior to sending signals. If the LBT is successful, the communication device can transmit the signal; if the LBT is not successful, the communication device cannot transmit the signal. Because the transmitting device has not determined when to transmit the signal, the receiving device must perform blind detection on reception to determine whether the transmitting device has successfully sent the signal. To ensure objectivity in a single transmission, the time during which a communication device uses an unlicensed spectrum channel to transmit a signal cannot exceed the maximum channel busy time (MCOT).

In the LTE system, in order to ensure reliability of uplink information, a downlink channel/signal is transmitted on an unlicensed spectrum, and uplink information corresponding to a downlink channel/signal is transmitted on a licensed spectrum.

The (NR) system must support independent operation, therefore it must support the transmission of uplink information corresponding to the downlink channel/signal on unlicensed spectrum.

In FIG. 2 shows a block diagram of a communication method 200 according to an embodiment of the present application. As shown in FIG. 2, method 200 includes some or all of the following:

step S210: the terminal apparatus receiving n downlink channel/signal sets on downlink resources during the channel busy time (COT), and each downlink channel/signal set in the n downlink channel/signal sets comprises at least one downlink channel/signal, and n is a positive integer greater than or equal to 1;

step S220: the terminal equipment transmitting uplink information corresponding to the i-th downlink channel/signal set in the n downlink channel/signal sets on the uplink resources during the COT, where i is a positive integer less than n;

wherein the transmission start time of the uplink information corresponding to the i-th downlink channel/signal set is based on the end time T0 of the i-th downlink channel/signal set, the downlink resource end time T1, and the channel processing delay time /downlink signal.

First, it should be noted that the downlink channel/signal may be a physical downlink shared channel (PDSCH) that carries information, and the uplink information corresponding to the PDSCH may be information with a feedback response, i.e. e. positive acknowledgment (ACK)/negative acknowledgment (NACK) information, wherein the downlink channel/signal can also be a channel state information reference signal (CSI-RS), and uplink information corresponding to the ACK/NACK information , may represent measurement information. The purpose of the CSI-RS for the terminal device is to obtain channel state information (CSI) in order to measure the downlink channel and feed back the measurement information to the network device. Optionally, the downlink channel/signal can also be cell specific reference signals (CRS), where the purpose of the CRS for the terminal device is also to obtain CSI in order to measure the downlink channel and feed back the measurement information to the network device.

In addition, the generation of the downlink channel/signal sets may be based on whether the corresponding uplink information is carried on the same channel, or based on other factors. For example, it may be based on chronological order to separate every two downlink channels/signals into a set. Embodiments of the present application do not restrict the generation of downlink channel/signal sets.

In embodiments of the present application, the n downlink channel/signal sets may be formed based on chronological order. For example, in n sets of downlink channels/signals, the end time of the first set of downlink channels/signals is earlier than the time of the second set of downlink channels/signals, the end time of the second set of downlink channels/signals is earlier, than the time of the third set of downlink channels/signals, and so on. Embodiments of the present application do not limit the start time of each downlink channel/signal set.

In embodiments of the present application, n downlink channel/signal sets may be formed based on the corresponding uplink information transmission sequence. For example, in n sets of downlink channels/signals, the start time of the uplink information corresponding to the first set of downlink channels/signals is earlier than the time of the uplink information corresponding to the second set of downlink channels/signals, time the start of the uplink information corresponding to the second set of downlink channels/signals is earlier than the time of the uplink information corresponding to the third set of downlink channels/signals, and so on.

One or more uplink and downlink transform points may be present during the COT. It is not limiting to embodiments of the present application that the downlink resource on which the downlink channel/signal is located is adjacent to the uplink resource. However, for convenience of description, the following implementations use a downlink resource and a neighboring uplink resource as an example.

The terminal device in embodiments of the present application may receive n downlink channel/signal sets on the downlink resource, and n can be understood as follows: if the (n+1)th downlink channel/signal set is sent on the downlink resource communication, then there is no resource that can send its corresponding uplink information on the uplink resource. Or n can also be understood as follows: the maximum target value of the downlink channel/signal sent by the network device and all uplink information corresponding to n sets of downlink channels/signals can be transmitted on the uplink resource.

The transmission start time of the uplink information corresponding to the i-th downlink channel/signal set can be determined by combining the end time T0 of the i-th downlink channel/signal set, the downlink resource end time T1, and the processing delay time downlink channels/signals. For example, the downlink channel/signal is the PDSCH and the corresponding uplink information is the ACK/NACK information, and the transmission start time of the ACK/NACK information is based on the PDSCH end time, the downlink resource end time, and the PDSCH processing delay time. As another example, the downlink channel/signal is CSI-RS and the corresponding uplink information is measurement information. The measurement information transmission start time is based on the end time of the CSI-RS, the end time of the downlink resources, and the delay time of the CSI processing.

Among these, the PDSCH processing delay time value may be influenced by the following factors: PDSCH decoding delay, a physical channel that carries corresponding uplink information such as a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH). ), a demodulation reference signal (DMRS) structure in the PDSCH, and a PDSCH resource mapping method. The CSI processing latency value is affected by the following factors: CSI calculation delay, CSI type (CSI Feedback Type I or CSI Feedback Type II), or CSI content (Channel Quality Indicator (CQI) only, CQI + Rank Indicator (RI) + precoding matrix indicator (PMI), CSI bandwidth, CSI subband, etc.), the structure of the reference signal used to calculate the CSI, and the physical channel (PUCCH or PUSCH) carrying the CSI.

Optionally, in embodiments of the present application, if the i-th downlink channel/signal set is the first downlink channel/signal set in the n-th downlink channel/signal set, then the start time of the uplink information corresponding to the first the downlink channel/signal set is directly determined based on the end time of the first downlink channel/signal set, the end time of the downlink resources, and the downlink channel/signal processing delay time. If the i-th downlink channel/signal set is the second set, third set, etc., of the downlink channels/signals in the n downlink channel sets, then the transmission start time of the uplink information corresponding to i i-th downlink channel/signal set is not only related to the end time of the i-th downlink channel/signal set, the downlink resource end time, and the downlink channel/signal processing delay time, but also to the transmission end time uplink information associated with the previous set of downlink channels/signals.

For example, for any downlink channel/signal set, the time value may be determined based on the downlink channel/signal set end time, the downlink resource end time, and the downlink channel/signal processing delay time. For the first set of downlink channels/signals, the determined time value may be considered as the start time of the transmission of the corresponding uplink information. For the second and subsequent set of downlink channels/signals, the greater of the determined time and end time of uplink information transmission corresponding to the previous set of downlink channels/signals is used as the start time of transmission of the corresponding uplink information.

Therefore, in the information transmission method according to the embodiments of the present application, the uplink information corresponding to the downlink channel/signal is transmitted on the uplink resource during the same COT, and the transmission start time of the corresponding uplink information is determined based on the end time corresponding downlink channel/signal, downlink resource end time, and downlink channel/signal processing delay time, which aims at reliable transmission of uplink information corresponding to the downlink channel/signal.

In combination with FIG. 3-5, the following will describe in detail how to determine the time value based on the end time of any set of downlink channels/signals, the end time of downlink resources, and the downlink channel/signal processing delay time.

As shown in FIG. 3, COT contains a downlink (DL) and an uplink (UL) resource. A downlink channel/signal (PDSCH is taken as an example herein) is transmitted on the DL, and its corresponding uplink information (ACK/NACK is taken as an example herein) is transmitted on the UL. The interval between the downlink resource and the downlink resource is G. The terminal device receives the PDSCH set at T0, i.e., the end time of the PDSCH set is T0. The PDSCH processing delay time is A. The downlink resource end time is T1. The determined time value is T2. If T0+A is less than or equal to T1+G, then T2 may be the start time of the uplink resource, or T1+G, or the start position of the first symbol starting from T1+G. Or, as shown in FIG. 3, A may be the difference between G and the PDSCH processing delay time, then if T0+A is less than or equal to T1, similarly T2 may be considered as T1+G. If this is the first set of PDSCHs, then T2 is the start time of transmission of the corresponding ACK/NACK. If it is a subsequent PDSCH set, then the maximum value of T2 and the end time of the ACK/NACK transmission corresponding to the previous PDSCH set may be considered the start time of the ACK/NACK transmission corresponding to the PDSCH set.

As shown in FIG. 4, COT contains a downlink (DL) and an uplink (UL) resource. A downlink channel/signal (PDSCH is taken as an example herein) is transmitted on the DL, and its corresponding uplink information (ACK/NACK is taken as an example herein) is transmitted on the UL. The interval between the downlink resource and the downlink resource is G. The terminal device receives the PDSCH set at T0, i.e., the end time of the PDSCH set is T0. The PDSCH processing delay time is A. The downlink resource end time is T1. The determined time value is T2. If T0+A is greater than T1+G, then T2 may be T0+A or the start position of the first symbol with T0+A. Or, as shown in FIG. 4, A may be the difference between G and the PDSCH processing delay time, then if T0+A is greater than T1, similarly T2 may be considered as T0+A. If this is the first set of PDSCHs, then T2 is the start time of transmission of the corresponding ACK/NACK. If it is a subsequent PDSCH set, then the maximum value of T2 and the end time of the ACK/NACK transmission corresponding to the previous PDSCH set may be considered the start time of the ACK/NACK transmission corresponding to the PDSCH set.

As shown in FIG. 5, two sets of downlink channels/signals received on a downlink resource are used as an example. The end time of the first PDSCH set is T0. The end time of the second PDSCH set is T0'. The downlink resource end time is T1. Since T0+A is less than T1+G, T2 may be considered the transmission start time of the ACK/NACK information corresponding to the first PDSCH set. And since T0'+A is greater than T1+G, T2' can be T0'+A. Since the transmission end time T3 of the ACK/NACK information corresponding to the first PDSCH set is longer than T2', T3 may be considered the start time of the transmission of the ACK/NACK information corresponding to the second PDSCH set.

It should be noted that in embodiments of the present application, A may be asserted via a protocol or configured via a network. It may be based on the downlink channel/signal processing delay plus or minus the offset. And G can also be asserted via a protocol or configured via a network. For example, G may be less than or equal to 16 µs, so the terminal device does not need to perform LBT before sending the corresponding uplink information, which is advantageous to avoid not being able to update the corresponding uplink information due to other communication devices occupying the channel.

It should be understood that the transmission start time of the uplink information corresponding to a particular set of downlink channels/signals determined by the terminal device may be a time value obtained based on the above decision methods. And, the time value may be considered the minimum transmission value of the corresponding uplink information. That is, after the time value is obtained, any value after the time value may be used as the transmission start time of the corresponding uplink information.

It should also be understood that the end time of the uplink information corresponding to each downlink channel/signal set may be asserted by a protocol or configured by a network. Or, the transmission time span of the uplink information corresponding to a particular set of downlink channels/signals may also be asserted or configured.

Optionally, in embodiments of the present application, the terminal device may determine the time value based on the end time of the first set of downlink channels/signals, the end time of downlink resources, and the downlink channel/signal processing delay time. Any value greater than or equal to the time value can be directly used as the transmission start time of the corresponding uplink information. The terminal device may also receive the network device configuration and compare the network configuration time with a specific time value, wherein if the network configuration time is less than the time value, the terminal device may consider it an invalid configuration and may use any value greater than or equal to the time value as the time. start transmission of the corresponding uplink information. If the network configuration time is greater than or equal to the time value, the terminal device can directly use the network configuration time as the transmission start time of the corresponding uplink information.

Optionally, in embodiments of the present application, the terminal device may determine the time value based on the end time of any downlink channel/signal set after the first set, the downlink resource end time, and the downlink channel/signal processing delay time. The maximum value of the time value and end time of transmission of the uplink information corresponding to the previous set of downlink channels/signals is used as the lower limit of the start time of transmission of the corresponding uplink information. The terminal device may also receive a network device configuration and compare the network configuration time with a selected maximum value. If the network configuration time is less than the maximum value, the terminal apparatus may consider the network configuration time to be a misconfiguration and take itself any value greater than or equal to the maximum value as the transmission start time of the corresponding uplink information. If the network configuration time is greater than or equal to the maximum value, the terminal device can directly use the network configuration time as the transmission start time of the corresponding uplink information.

Optionally, in embodiments of the present application, if the end time of n downlink channel/signal sets is less than T1, the method further includes receiving the specific downlink channel/signal/information by the terminal device between the end time of n downlink channel/signal sets and T1. Wherein, specific downlink channel/signal/information does not have corresponding uplink information, or specific downlink channel/signal/information is a common channel/signal/information.

It should be understood that in embodiments of the present application, the end time of a particular downlink channel/signal set refers to the last time of the downlink channel/signal set. The end time of n downlink channel/signal sets in the embodiments of the present application also refers to the last end time of n downlink channel/signal sets. The n downlink channel/signal sets are described above and will not be repeated here for brevity.

The terminal device may receive a specific type of downlink channel/signal/information on the downlink resources after n sets of downlink channels/signals. For example, a particular downlink channel/signal/information may not have corresponding uplink information, or a particular downlink channel/signal/information may be one or more of a broadcast channel, synchronization signal, CSI-RS, downlink control channel communication and common signaling of the UE set, or he/she may be some information that may appear in the future, for example, the information may not be carried over the channel.

Optionally, in the embodiments of the present application, if the transmission start time of the uplink information corresponding to the i-th downlink channel/signal set is greater than the start time of the uplink resources or the end time of the transmission of the uplink information corresponding to (i-1 )-th downlink channel/signal set, the method further includes: sending the specific uplink channel/signal between the uplink resource start time and the uplink information transmission start time corresponding to the i-th downlink channel/signal set or sending by the terminal device of a particular uplink between the end time of uplink information transmission corresponding to the (i-1)-th set of downlink channels/signals and the start time of transmission of uplink information corresponding to the i-th set channels/signal downlink fishing; wherein the particular uplink channel/signal contains at least one of the following information: information used for busyness, sounding reference signal (SRS), physical uplink shared channel (PUSCH), and demodulation reference signal (DMRS).

In particular, the information used for busyness has no practical effect of preventing other communication devices from occupying the channel during this period of time. The PUSCH may refer to the prescheduled PUSCH, and the network device may send scheduling signaling information to the downlink resource during the COT for PUSCH scheduling. Or, the network device may also schedule the PUSCH by configuring the high layer signaling. DMRS, a frequency domain resource for transmitting DMRS, may be the same as a frequency domain resource for transmitting corresponding uplink information. The terminal device can transmit DMRS in advance, and DMRS resources can no longer be reserved on a channel carrying corresponding uplink information, which is advantageous for increasing transmission efficiency.

The terminal device may transmit the above specific uplink channel/signal/information between the uplink resource start time and the uplink information transmission start time corresponding to the first set of downlink channels/signals. And the terminal device can also transmit the above specific uplink channel/signal/information between the transmission start times of the uplink information corresponding to each two sets of downlink channels/signals.

In FIG. 6 shows a schematic representation of a communication method 300 according to an embodiment of the present application. As shown in FIG. 6, method 300 includes some or all of the following:

step S310: the network device sends n downlink channel/signal sets to the terminal device on the downlink resources during the channel busy time, COT, and each downlink channel/signal set in the n downlink channel/signal sets contains at least one downlink channel/signal, where n is a positive integer greater than or equal to 1;

Optionally, in embodiments of the present application, the method further includes sending, by the network device, configuration information to the terminal device, and wherein the configuration information is for indicating a start time for receiving uplink information corresponding to the i-th downlink channel/signal set, wherein the time specified configuration information is not earlier than the first threshold, and the first threshold is the maximum end time of receiving uplink information corresponding to the (i-1)th downlink channel/signal set, end time T0 of i- th downlink channel/signal set, downlink resource end time T1, and processing delay time.

Optionally, in embodiments of the present application, if (T0+A) is less than or equal to (T1+G), the time determined based on T0, T1 and the processing delay time is (T1+G) or the start position of the first symbol c (T1 +G). Wherein, A is a processing delay time and G is an interval between a downlink resource and an uplink resource.
