Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terms "first," "second," and the like in this application are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in this application means at least one of the connected objects, such as a and/or B and/or C, is meant to encompass the 7 cases of a alone, B alone, C alone, and both a and B, both B and C, both a and C, and both A, B and C.
Referring to fig. 1, fig. 1 is a block diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a network side device 12, where communication can be performed between the terminal 11 and the network side device 12.
In the embodiment of the present invention, the terminal 11 may also be referred to as a User Equipment (UE). In practical applications, the terminal 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet Device (Mobile Internet Device, MID), a Wearable Device (webable Device), a vehicle-mounted Device, or the like. The network-side device 12 may be a base station, relay or access point, or the like.
For ease of understanding, some of the following descriptions are directed to embodiments of the present invention:
on the unlicensed band of NR, a terminal or a network side device needs to make LBT before transmitting information. Specifically, the terminal or the network side device needs to do CCA or eCCA to listen to the channel, that is, perform ED, and when the energy is lower than a certain threshold, the channel is judged to be empty, and the party can start transmission. Since the unlicensed band is shared by multiple technologies or multiple transmission nodes, the contention-based access manner causes uncertainty of a channel Available time, and when a channel is Available (Available), a transmissible position of a signal transmission of a network side device may be missed and cannot be transmitted, which may cause that a receiving end cannot normally receive signal reception configured on the network side, and terminal behaviors performed according to configuration on the network side after the signal reception, such as physical downlink control channel (Physical Downlink Control Channel, PDCCH) monitoring, monitoring and measurement of a wireless environment, and the like. The process of determining whether a channel is clear and transmitting by means of CCA may be referred to as a channel access process.
Is now clearly available for the fifth generation (5 th The channel access procedure category of the Generation, 5G) unlicensed communication system is as follows:
cat 1, do not make any CCA direct transmission, must be available with transmission transition intervals less than 16 microseconds (us) if a channel has been acquired;
cat 2 (Type II) to perform channel listening for 16us or 25us, which may be used for a particular signal acquisition channel, the maximum continuous transmission length should be less than a certain value, e.g. 1 millisecond (ms);
cat 4 (Type I) is to perform random back channel interception, set different priority parameters, and finally obtain different maximum length of the channel for transmission.
1. A method of indicating COTs in an licensed assisted access (License Assisted Access, LAA)/Enhanced licensed assisted access (eLAA) eLAA/Further Enhanced licensed assisted access (FeLAA).
The terminal of the LAA/eLAA/FeLAA monitors DCI format 1C scrambled by the CC-RNTI in a control time zone of each Subframe (Subframe) to acquire COT related information.
The subframe configuration (Subframe configuration for LAA) field of the LAA of the downlink control information (Downlink Control Information, DCI) format (format) 1C may indicate the current subframe or the next subframe downlink symbol occupation situation. The function of the COT end subframe as a Partial (Partial) subframe can be realized by the indication. Meanwhile, if no DCI format 1C is detected in subframe n-1, and the DCI detected in subframe n indicates that the number of current DL symbols is less than 14, the terminal monitors PDCCH or ePDCCH only in the subframe.
The uplink duration and offset (UL duration and offset) field of DCI format 1C may indicate which subframes are uplink transmissions in the COT time. On these subframes, the terminal does not need to monitor any downlink signal.
The base station can indicate the uplink subframe dynamically scheduled in the COT through the domain, and can update the channel access type indicated by the original UL grant;
the base station may indicate that an Autonomous Uplink (UL) transmission may use Type 2 Channel Access (Channel Access), i.e., shared COT, through the domain and an Autonomous uplink Channel occupied time Sharing (AUL COT Sharing) domain. The base station can set the domain to True only after acquiring the channel using the lowest priority Cat 4.
2. The slot format indication (Slot Format Indication, SFI) in NR Rel15 indicates the method.
In NR Rel15, flexible configuration is performed by combining semi-static (RRC configuration) radio resource control and dynamic downlink control information configuration.
DCI format 2_0 is specially used as an SFI indication, and may configure SFIs on multiple serving cells (serving cells), that is, multiple SFI indication (Indicator) fields, where the starting bit position of the SFI Indicator field corresponding to each serving cell is indicated in RRC. For a single slot, the maximum number of formats supported by NR Rel15 is 256, including D (Downlink), U (Uplink) or F (Flexible) for each symbol indicating slots. For each serving cell, the base station may configure a number slot format combination (512 maximum) through RRC, and each slot format combination may indicate a format of 1-256 slots.
Symbols allocated as U by SFI should not be used for other DCI format scheduling for reception of PDSCH or CSI-RS; the symbol allocated as D by SFI should not be scheduled for PUSCH, PUCCH, PRACH or SRS transmission by other DCI formats. The flexible symbol indicated by the SFI may be PDSCH or CSI-RS received by DCI scheduling, or PUSCH, PUCCH, PRACH or SRS may be transmitted by DCI scheduling.
The following describes a method for indicating the COT according to the embodiment of the present invention.
Referring to fig. 2, fig. 2 is one of flowcharts of a method for indicating COT according to an embodiment of the present invention. The indication method of the channel occupation time COT is applied to the terminal.
As shown in fig. 2, the method for indicating the channel occupation time COT applied to the terminal may include the steps of:
step 201, receiving first indication information, where the first indication information is used to indicate related information of a first COT.
Wherein the related information includes at least one of: the transmission state of the time domain resource of the first COT, the ending time domain resource of the first COT and the identification information of the first COT.
In specific implementation, the first instruction information may be downlink control information (Downlink Control Information, DCI) or slot format instruction (Slot Format Indication, SFI), and the present invention is not limited to the specific form of the first instruction information.
The time unit of the time domain resource may be a subframe, a Slot (Slot) or a Symbol (Symbol), which may be specifically determined according to actual requirements, which is not limited in the embodiment of the present invention.
For easy understanding, the following description will be given below for each item of information that the related information may include:
1. and the transmission state of the time domain resource of the first COT.
Optionally, the transmission state of the time domain resource may include at least one of: uplink transmission, target downlink transmission and flexible transmission.
Note that the transmission states of different time domain resources in the first COT may be the same or different. If the transmission status of the time domain resource 1 in the first COT is uplink transmission, the transmission status of the time domain resource 2 and the time domain resource 3 in the first COT is target downlink transmission, and the transmission status of the time domain resource 4 in the first COT is flexible transmission.
In this embodiment, if the transmission status of a certain time domain resource is uplink, it is described that the time domain resource needs to transmit an uplink signal and/or an uplink channel, for example, transmission of a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), transmission of a sounding reference signal (Sounding Reference Signal, SRS), transmission of a PUCCH, transmission of a physical random access channel (Physical Random Access Channel, PRACH), and the like.
If the transmission status of a certain time domain resource is the target downlink transmission, it indicates that the time domain resource needs to perform downlink signal and/or downlink channel monitoring, such as physical downlink control channel (Physical Downlink Control Channel, PDCCH) monitoring, reference signal monitoring, and the like.
If the transmission status of a certain time domain resource is flexible transmission, the specific function of the time domain resource needs to be determined by combining the position of the time domain resource in the first COT, which is specifically described as follows:
if the time domain resource is located between the fifth time domain resource and the sixth time domain resource of the first COT, the time domain resource may be regarded as a converted time domain resource, and the time domain resource does not need to perform: and sending uplink signals and uplink channels, and monitoring downlink signals and downlink channels.
If the time domain resource is not located between the fifth time domain resource and the sixth time domain resource of the first COT, the time domain resource may be regarded as a resource to be scheduled, and the transmission state of the time domain resource may be switched to the target downlink transmission or the target uplink transmission.
Wherein, the transmission states of the time domain resources between the fifth time domain resource and the sixth time domain resource are flexible transmission; the transmission states of the fifth time domain resource and the sixth time domain resource are respectively target downlink transmission and uplink transmission. The fifth time domain resource may precede the sixth time domain resource or follow the sixth time domain resource.
For ease of understanding, examples are illustrated below:
assuming that the first COT includes consecutive symbols 1, 2, 3, 4, 5 and 6, the transmission state of the symbol 1 is downlink transmission, the transmission states of the symbol 2 and 3 are flexible transmission, the transmission state of the symbol 4 is uplink transmission, the transmission state of the symbol 5 is flexible transmission, and the transmission state of the symbol 6 is uplink transmission. If the target downlink transmission is D, the flexible transmission is F, and the uplink transmission is U, the transmission states of symbol 1, symbol 2, symbol 3, symbol 4, symbol 5, and symbol 6 are dffu in sequence.
Since the F-state symbols 2 and Slo3 are located between the D-state symbol 1 and the U-state symbol 4, they can be regarded as transition symbols, and transmission of uplink signals and uplink channels, and interception of downlink signals and downlink channels are not performed.
For symbol 5 in the F state, since it is located between symbol 4 in the U state and symbol 6 in the U state, it can be regarded as a symbol to be scheduled, and it can be switched to the D state or the U state.
In this embodiment, further, the target downlink transmission may include at least one of the following: first downlink transmission and second downlink transmission.
The difference between the time domain resource with the transmission state of the first downlink transmission and the time domain resource with the transmission state of the second downlink transmission is that: the time domain resource with the transmission state of the first downlink transmission can be monitored by a downlink channel, and the time domain resource with the transmission state of the second downlink transmission can not be monitored by the downlink channel. However, both the time domain resource with the transmission state of the first downlink transmission and the time domain resource with the transmission state of the second downlink transmission can have monitoring of downlink signals.
In this embodiment, optionally, the first indication information may indicate a transmission state of the time domain resource of the first COT through a bit map.
In a specific implementation, the first indication information may indicate the transmission state of the time domain resource of the first COT in the following two manners.
First mode
In the first manner, each bit group in the bitmap may correspond to one time domain resource in the first COT, and each bit group is used to indicate a transmission state of its corresponding time domain resource. Wherein the time domain resources corresponding to different bit groups are different.
Different values of the bit groups may be used to indicate different transmission states. The group of bits comprises bits that are related to the number of transmission states.
Such as: the transmission state includes four kinds, and the bit group may include two bits. For example, a bit group with a value of 00 may indicate that the transmission state of the corresponding time domain resource is uplink transmission, a bit group with a value of 01 may indicate that the transmission state of the corresponding time domain resource is first downlink transmission, a bit group with a value of 10 may indicate that the transmission state of the corresponding time domain resource is second downlink transmission, and a bit group with a value of 11 may indicate that the transmission state of the corresponding time domain resource is flexible transmission.
In the first aspect, since each bit group is used to indicate the transmission state of the corresponding time domain resource, the terminal may directly obtain the transmission state of the time domain resource of the first COT based on the bit map.
Second mode
In a second mode, an association relationship between transmission states of time domain resource groups and index numbers is preconfigured, and in the association relationship, transmission states of time domain resource groups corresponding to different index numbers are different. Thus, each bit group in the bit map may correspond to one time domain resource group in the first COT, each bit group indicating an index number to which its corresponding time domain resource group corresponds.
The number of time domain resources included in the time domain resource group is determined based on a time unit of the time domain resource, alternatively, in a case where the time unit of the time domain resource is a symbol, one time domain resource group may include 14 symbols, i.e., one time domain resource group forms one Slot.
The transmission state of the time domain resource group is used to indicate the transmission state of each time domain resource included in the time domain resource group. Such as: in the case that one time domain resource group may include 14 symbols, if the transmission state of the time domain resource group is ddddffffffuuu, the transmission states of the first 4 symbols of the time domain resource group are all target downlink transmissions, the transmission states of the 5 th symbol to the 10 th symbol of the time domain resource group are all flexible transmissions, and the transmission states of the last 4 symbols of the time domain resource group are all uplink transmissions.
Different values of the bit groups may be used to indicate different index numbers. The group of bits comprises bits that are related to the number of index numbers.
Such as: if the number of index numbers is 256, that is, the transmission state of 256 time domain resource groups is preset, each bit group may include 8 bits. Illustratively, the bit set with a value of 00000000 corresponds to an index number of 1, the bit set with a value of 00000001 corresponds to an index number of 2, and so on.
In the second mode, since each bit group indicates the index number corresponding to the corresponding time domain resource group, after the terminal obtains the index number corresponding to a certain time domain resource group, the terminal needs to search the association relationship to determine the transmission state of each time domain resource in the time domain resource group.
Each bit group does not include the same bits, and each bit group includes bits that are consecutive. It should be noted that, in the present embodiment, the bit group is only used for convenience of description, and the representation form of the bit map is not limited.
For ease of understanding, examples are illustrated below:
assume that the first COT comprises two consecutive slots: slot1 and Slot2, each Slot comprising 14 symbols, note that Slot1 comprises symbols 1 through 8, and Slot comprises symbols 9 through 16. The transmission states of symbols 1 to 8 are dffuuuu in turn, and the transmission states of symbols 9 to 16 are DFFDDDDD in turn. In addition, the time unit of the time domain resource is Slot.
In the first mode, assuming that the transmission states are 4 types, each bit group needs to include two bits, and a bit group with a value of 00 may indicate that the transmission state of the corresponding time domain resource is U, a bit group with a value of 01 may indicate that the transmission state of the corresponding time domain resource is D, and a bit group with a value of 11 may indicate that the transmission state of the corresponding time domain resource is F.
The bit map requires 32 bits to indicate the transmission status of each time domain resource in the first COT. In the case where 32 bits sequentially indicate symbols 1 to 16, the values of the 32 bits are sequentially: 01 11 11 00 00 00 00 00 01 11 11 01 01 01 01 01.
In the second mode, assuming that the number of index numbers is 256, each bit group needs to include 8 bits. The index number corresponding to the bit group having a value of 00000000 is 1, and the index number corresponding to the bit group having a value of 00000001 is 2. In the above association, the transmission state of the time domain resource group corresponding to the index number 1 is dffuuuu, and the transmission state of the time domain resource group corresponding to the index number 2 is DFFDDDDD.
The bit map requires 16 bits to indicate the transmission status of each time domain resource in the first COT. In the case where 16 bits sequentially indicate symbols 1 to 16, the values of the 16 bits are sequentially: 00000000 00000001.
It can be seen that in some cases, the bits required in the second mode are less than the bits required in one mode, and in these cases, the signaling overhead can be reduced by indicating the transmission status of the time domain resource in the first COT in the second mode.
2. And ending time domain resources of the first COT.
In this embodiment, in a specific implementation, the first indication information may indicate the ending time domain resource of the first COT in a plurality of manners, which is specifically described as follows:
mode one, the first indication information indicates: offset time information of the ending time domain resource relative to a first reference time, wherein the first reference time is: the time at which the first indication information is detected.
In a first aspect, the first indication information indicates the end time domain resource of the first COT indirectly by indicating the offset time information. In this way, the terminal can determine the position of ending the time domain resource by combining the first reference time and the offset time information.
In particular implementations, the specific form of the offset time information may be determined based on the first reference time and the time unit of the time domain resource, which is not limited by the present invention.
Alternatively, in the case that the time unit of the first reference time is Slot and the time unit of the time domain resource is Symbol, the Offset time information may include Slot Offset (Offset) and Symbol Index (Index) of the end time domain position with respect to the first reference time.
Illustratively, let Slot1, slot2, slot3, and Slot4 be 4 consecutive slots. And if the terminal detects the first indication information in the Slot1, the Slot Offset is 3 slots, the Symbol Index indicates the 3 rd Symbol of the Slot, and the position of ending the time domain resource is the 3 rd Symbol of the Slot 4.
Mode two, the first indication information indicates: residual time information of the first COT relative to a second reference time, wherein the second reference time is: any time domain resource of a physical downlink control channel PDCCH associated with the first indication information, or any time domain resource of a control resource set (Control Resource Set, CORESET) associated with the first indication information.
In the second aspect, the first indication information indicates the ending time domain resource of the first COT indirectly by indicating the remaining time information. In this way, the terminal can determine the position of ending the time domain resource by combining the second reference time and the remaining time information.
The remaining time information may be used to indicate a remaining COT length of the first COT relative to a second reference time. In particular implementations, the remaining time information may be embodied in terms of time units of the time domain resource.
Alternatively, in case that the time unit of the time domain resource is a symbol, the remaining time information may be expressed as the number of symbols of the remaining COT.
For example, assuming that symbols 1 to 8 are consecutive, the second reference time is symbol 1, the remaining time information indicates that the number of symbols of the remaining COT is 7, and the ending time domain position is symbol 8.
In addition, in specific implementation, the second reference time may be a start time domain resource or an end time domain resource of the PDCCH or CORESET associated with the first indication information, but is not limited thereto.
Mode three, the first indication information indicates: and the identification information of the ending time domain resource.
In the third mode, the first indication information directly indicates the ending time domain resource of the first COT through identification information indicating the ending time domain resource. In this way, the terminal can directly determine the position of the identification information indicating the ending time domain resource as the position of the ending time domain resource.
In a specific implementation, optionally, the first indication information may indicate the identification information of the ending time domain resource through a bitmap.
The manner in which the first indication information indicates the identification information of the ending time domain resource through the bitmap is similar to the manner in which the first indication information indicates the transmission state of the time domain resource of the first COT through the bitmap, and the foregoing description may be referred to specifically, and will not be repeated here.
Meanwhile, the first indication information indicates: in one implementation manner, the terminal may indicate the transmission state of the time domain resource of the first COT and the ending time domain resource of the first COT through different bit maps respectively.
In another implementation, the terminal may indicate, through the same bitmap, a transmission state of the time domain resource of the first COT and an ending time domain resource of the first COT, respectively.
Corresponding to the foregoing first aspect, optionally, each bit group of the bit map may include three bits, where the first two bits of each bit group are used to indicate a transmission state of the time domain resource of the first COT, and the last bit is used to indicate whether the time domain resource is an ending time domain resource.
For example, if the third bit of the bit group has a value of 0, it indicates that the time domain resource corresponding to the bit group is not the ending time domain resource; if the third bit of the bit group takes a value of 1, the time domain resource corresponding to the bit group is the ending time domain resource.
Corresponding to the foregoing second mode, optionally, a first transmission state of the time domain resource group may be set in the association relationship, where a certain time domain resource is indicated as ending time domain resource. Such as: and recording the identification information of the ending time domain resource as E, and if the transmission state of the time domain resource group is DDDDFFFFFFUUUE under the condition that one time domain resource group comprises 14 symbols, indicating that the last symbol is the ending time domain resource.
Fourth mode, the first indication information indicates: identification information of the time domain resource outside the first COT.
In a fourth aspect, the first indication information indirectly indicates the ending time domain resource of the first COT through identification information indicating the time domain resource other than the first COT. In this way, the terminal can determine the previous time domain resource of the first time domain resource identified with the identification information as the location where the time domain resource ends.
In a specific implementation, optionally, the first indication information may indicate, by using a bitmap, identification information of a time domain resource other than the first COT.
The manner in which the first indication information indicates the identification information of the ending time domain resource through the bitmap is similar to the manner in which the first indication information indicates the transmission state of the time domain resource of the first COT through the bitmap, and the foregoing description may be referred to specifically, and will not be repeated here.
In practical applications, the bit map for indicating the time domain resources other than the first COT and the bit map for indicating the other information of the first COT may be the same bit map or may be different bit maps.
In a scenario where the same bitmap is used to indicate the transmission status of the time domain resource of the first COT and the identification information of the time domain resource other than the first COT, each bit group of the bitmap may optionally include three bits, where the first two bits of each bit group are used to indicate the transmission status of the time domain resource of the first COT, and the last bit is used to indicate whether the time domain resource is the time domain resource other than the first COT.
For example, if the third bit of the bit group has a value of 0, it indicates that the time domain resource corresponding to the bit group is not a time domain resource other than the first COT; if the third bit of the bit group takes a value of 1, it indicates that the time domain resource corresponding to the bit group is a time domain resource other than the first COT.
Corresponding to the foregoing second manner, optionally, a second transmission state of the time domain resource group may be set in the association relationship, and in the second transmission state of the time domain resource group, the time domain resources in the time domain resource group may be indicated as time domain resources other than the first COT. Such as: and recording the identification information of the time domain resources except the first COT as O, and if the transmission state of the time domain resource group is DDDDFFFFFFEOOO under the condition that one time domain resource group comprises 14 symbols, indicating that the 11 th symbol in the time domain resource group is the ending time domain resource of the first COT, and the 12 th symbol and the 14 th symbol are the time domain resources except the first COT.
It should be understood that, in practical applications, the network side may indicate the ending time domain resource of the first COT in at least two ways of the first to fourth ways, so as to improve accuracy of the ending time domain resource indication of the first COT.
3. And the identification information of the first COT.
In this embodiment, the identification information of the first COT may be used to determine the COT indicated by the first indication information, so as to facilitate the terminal to distinguish whether the COTs indicated by different indication information are the same COT.
In an implementation manner, the first indication information may directly carry identification information of the first COT, so as to identify the COT indicated by the first indication information.
In another implementation manner, optionally, in a case where the first indication information indicates the identification information of the first COT, the first indication information is specifically configured to indicate:
whether the first COT and the second COT are the same COT;
the second COT corresponds to second indication information, and the second indication information is the last indication information corresponding to the COT received before the terminal receives the first indication information.
Specifically, if the first COT and the second COT are the same COT, the first indication information and the second indication information are used to indicate the related information of the same COT, and since the first indication information is subsequent to the second indication information, the terminal may update the related information of the COT based on the first indication information, so that the flexibility of determining the related information of the COT may be improved.
And 202, executing operation on the first COT according to the first indication information.
In specific implementation, the terminal executes an operation at the first COT according to the related information of the first COT indicated by the first indication information. Thus, it can be appreciated that the operations performed by the terminal at the first COT are related to the specific structure of the first COT, which is described in detail below.
Optionally, the first indication information indicates that a transmission state of the first time domain resource of the first COT is: uplink transmission or target downlink transmission;
and executing an operation on the first COT according to the first indication information, wherein the operation comprises the following steps:
and stopping performing the idle channel detection (CCA) on the first time domain resource.
The first time domain resource may be any time domain resource in the first COT.
In practical applications, when the first indication information indicates that the transmission status of the first time domain resource is uplink, the terminal may default that there is certain uplink transmission in the first time domain resource, so that downlink transmission and/or CCA in the first time domain resource may be stopped.
When the first indication information indicates that the transmission status of the first time domain resource is the target downlink transmission, the terminal may default that there is a certain downlink transmission in the first time domain resource, and therefore may stop uplink transmission and/or CCA in the first time domain resource.
In this way, by stopping performing the clear channel detection CCA at the first time domain resource, terminal power consumption may be reduced.
Optionally, the first indication information indicates that a transmission state of the second time domain resource of the first COT is: a first downlink transmission;
and executing an operation on the first COT according to the first indication information, wherein the operation comprises the following steps:
and under the condition that the second time domain resource is configured with a search space, physical Downlink Control Channel (PDCCH) monitoring is performed on the second time domain resource.
The second time domain resource may be any time domain resource in the first COT.
Optionally, the first indication information indicates that a transmission state of the third time domain resource of the first COT is: a second downlink transmission;
and executing an operation on the first COT according to the first indication information, wherein the operation comprises the following steps:
and stopping performing PDCCH monitoring on the third time domain resource.
The third time domain resource may be any time domain resource in the first COT.
In this case, even if the radio resource control (Radio Resource Control, RRC) allocates a search space in the third time domain resource, the terminal does not perform PDCCH monitoring in the third time domain resource.
In this way, by stopping the PDCCH monitoring at the third time domain resource, terminal power consumption can be reduced.
Optionally, the first indication information indicates that a transmission state of the fourth time domain resource of the first COT is: flexible transmission;
and executing an operation on the first COT according to the first indication information, wherein the operation comprises the following steps:
detecting whether the fourth time domain resource meets a first preset condition or not;
stopping executing at least one of the following in the fourth time domain resource if the fourth time domain resource meets the first preset condition: downlink transmission, uplink transmission, CCA;
wherein, the first preset condition is: the fourth time domain resource is located between the fifth time domain resource and the sixth time domain resource of the first COT; the transmission states of the time domain resources between the fifth time domain resource and the sixth time domain resource are flexible transmission; the transmission states of the fifth time domain resource and the sixth time domain resource are respectively target downlink transmission and uplink transmission.
From the foregoing, it can be seen that the specific function of the time domain resource whose transmission status is flexible transmission needs to be determined in combination with the location of the time domain resource in the first COT. Therefore, for the fourth time domain resource, the terminal needs to further detect whether the fourth time domain resource meets the first preset condition.
Specifically, if the first preset condition is met, the fourth time domain resource may be regarded as a converted time domain resource, so that transmission and/or CCA of the fourth time domain resource may not be performed any more, and thus the power consumption of the terminal may be reduced.
If the first preset condition is not satisfied, the fourth time domain resource can be regarded as a time domain resource to be scheduled. From the foregoing, it can be seen that, for a time domain resource to be scheduled, its transmission state may be switched to a target downlink transmission or an uplink transmission. Thus, optionally, after said detecting whether the fourth time domain resource meets the first preset bar, the method further comprises:
if the fourth time domain resource does not meet the first preset condition, executing any one of the following steps:
under the condition that third indication information is received, executing operation on the fourth time domain resource according to the transmission state of the fourth time domain resource indicated by the third indication information;
and under the condition that the third indication information is not received, executing operation on the fourth time domain resource according to the transmission state of the fourth time domain resource before the terminal receives the first indication information.
The third indication information may be understood as scheduling indication information of a transmission state of the fourth time domain resource, and may schedule the transmission state of the fourth time domain resource as uplink transmission or target downlink transmission.
If the terminal receives the third indication information and the third indication information schedules the transmission state of the fourth time domain resource as uplink transmission, the terminal needs to perform uplink transmission on the fourth time domain resource, and does not perform downlink transmission and/or CCA on the fourth time domain resource.
If the terminal receives the third indication information and the third indication information schedules the transmission state of the fourth time domain resource as the target downlink transmission, the terminal needs to perform downlink transmission on the fourth time domain resource, and does not perform uplink transmission and/or CCA on the fourth time domain resource.
If the terminal does not receive the third indication information, the terminal defaults the transmission state of the fourth time domain resource to the transmission state of the fourth time domain resource before the terminal receives the first indication information.
Such as: assuming that the transmission state of the fourth time domain resource is uplink transmission before the terminal receives the first indication information, the transmission state of the fourth time domain resource may be switched to uplink transmission.
Assuming that the transmission state of the fourth time domain resource is the target downlink transmission before the terminal receives the first indication information, the transmission state of the fourth time domain resource may be switched to the target downlink transmission.
Optionally, in the case that the first indication information indicates that there is an ending time domain resource of the first COT, the performing, according to the first indication information, an operation at the first COT includes at least one of:
if a seventh time domain resource which does not indicate the transmission state exists in the first COT, configuring the transmission state of the seventh time domain resource into flexible transmission;
ignoring an indication of time domain resources other than the first COT by the first indication information;
and configuring the transmission state of the ending time domain resource to be the same as the transmission state of an eighth time domain resource, wherein the eighth time domain resource is the last time domain resource of the ending time domain resource.
For ease of understanding, examples are illustrated below:
assuming that the first COT includes symbols 1 to 10, symbol 10 is an ending time domain resource of the first COT.
If the first indication information does not indicate the transmission states of the symbols 2 to 8, the terminal may configure the transmission states of the symbols 2 to 9 to be flexible states.
If the first indication information indicates that there is a transmission status from symbol 11 to symbol 14, and since symbol 11 to symbol 14 do not belong to the first COT, the terminal may ignore the indication of the transmission status from symbol 11 to symbol 14 by the first indication information.
If the first indication information indicates that the transmission state of the symbol 9 is uplink, since the symbol 9 is the last time domain resource of the symbol 10, the transmission state of the symbol 10 may be configured as uplink.
Optionally, before the first COT performs an operation according to the first indication information, the method further includes:
receiving configuration information, wherein the configuration information is configured: the terminal executes first type Listen Before Talk (LBT) on a ninth time domain resource of the first COT, and after the first type LBT is successful, uplink transmission is carried out on the ninth time domain resource;
and executing an operation on the first COT according to the first indication information, wherein the operation comprises the following steps:
under the condition that the ninth time domain resource meets a second preset condition, executing a second type of LBT on the ninth time domain resource, and after the second type of LBT is successful, carrying out uplink transmission on the ninth time domain resource;
wherein the ninth time domain resource meeting the second preset condition includes any one of the following:
the transmission state of the ninth time domain resource is uplink transmission;
the transmission state of the ninth time domain resource is flexible transmission, and the ninth time domain resource does not meet a third preset condition, where the third preset condition is that the ninth time domain resource is located between a fifth time domain resource and a sixth time domain resource of the first COT; the transmission states of the time domain resources between the fifth time domain resource and the sixth time domain resource are flexible transmission; the transmission states of the fifth time domain resource and the sixth time domain resource are respectively target downlink transmission and uplink transmission.
In this embodiment, after receiving the configuration information, if the time domain resource configured by the configuration information meets the second preset condition, the terminal may change the type of LBT, perform LBT not according to the type of LBT configured by the configuration information, and perform shared COT transmission on the ninth time domain resource.
Further, the listening duration of the second type of LBT is shorter than the listening duration of the first type of LBT. Alternatively, the first type of LBT may be a Cat4 LBT and the second type of LBT may be a Cat2 LBT.
In addition, in this embodiment, if the ninth time domain resource does not meet the second preset condition, the terminal may not perform LBT on the ninth time domain resource and perform uplink transmission, so that power consumption may be reduced.
In this embodiment, when the first indication information indicates that the transmission state of a time domain resource is the target downlink transmission, the transmission state of the time domain resource may be specifically the first downlink transmission or the second downlink transmission.
According to the COT indication method, the terminal can acquire the relevant information of the COT and execute the operation according to the acquired relevant information of the COT, so that part of unnecessary operations can be reduced, and power consumption is further reduced.
It should be noted that, the various alternative embodiments described in the embodiments of the present invention may be implemented in combination with each other, or may be implemented separately, which is not limited to the embodiments of the present invention.
The invention provides a method for indicating a channel occupation time structure based on different symbol states defined in a time slot.
1. May include a combination of one or more of the following indications:
1) And indicating a downlink transmission state D: indicating the terminal that the symbol is downlink transmission, and monitoring downlink signals/channels, such as PDCCH monitoring, reference signal monitoring and the like, needs to be carried out;
wherein, the symbol with downlink signal transmission and containing PDCCH transmission is further indicated as P state; otherwise, the D state is indicated.
2) And indicating an uplink transmission state U: the indication terminal indicates that the symbol is uplink transmission, and can perform uplink signal/channel transmission, such as PUSCH transmission, SRS transmission, PUCCH transmission, PRACH transmission, and the like;
3) Indicating flexible transmission state F:
when the F state symbol is positioned between the D state symbol and the U state symbol in the same COT, the terminal is instructed not to perform any receiving and transmitting processing;
otherwise, the F state symbol indicates the terminal that the symbol is not scheduled, the terminal does not change, and the receiving and transmitting processing is carried out according to the original configuration.
4) Indicating the COT end time:
option 1, indicating the specific position of the ending symbol, namely slot offset and symbol index relative to the current slot;
option 2, indicating the length of the remaining COT, such as the number of symbols of the remaining COT, the reference point in time being the start or end symbol of the PDCCH or CORESET with which the DCI is detected;
option 3 COT end symbol indicates COT end state E;
option 4-COT Out-of-COT state O is indicated, then the one symbol preceding the first O-state symbol is the COT end symbol.
5) Identification information indicating the COT:
option 1, using the 1bit toggle bit indication to indicate whether it is a newly acquired COT relative to the last SFI;
option 2-introduction of COT Identification (ID) indication.
2. Based on the user behavior indicated by the COT.
1) When the symbol is indicated as a downlink (D) state, the user assumes that there must be a downlink transmission on the symbol, no uplink signal (including SRS, PUCCH, PUSCH, PRACH, etc.) is sent, and/or no CCA is performed.
Alternatively, when there is a P-state indication, the user performs PDCCH monitoring on the P-state symbol if the RRC configures the search space, and does not perform PDCCH monitoring on the D-state symbol (even if the RRC configures the search space).
2) When the symbol is indicated as a downlink (U) state, the user assumes that there must be an uplink transmission on the symbol, no downlink signal reception or measurement is performed (PDCCH, PDSCH, SSB, CSI-RS, etc.), and/or no CCA is performed;
3) When the symbol is indicated as a flexible (F) state, if the F symbol is between the indicated D (or P) symbol and U symbol, the user assumes that the symbol is a transition symbol, and neither any uplink signal transmission nor any downlink signal reception or measurement is performed; otherwise, the user assumes that the symbol is a to-be-scheduled symbol, and needs to continuously monitor the subsequent COT indication to update the symbol state, and the symbol can perform downlink signal transmission or uplink signal transmission.
4) When the symbol is determined or indicated as a COT end symbol, the indication state of the symbol in the COT is a valid state, and the non-indicated symbol is a flexible state; the indication outside the COT is an invalid indication. When the symbol indicates the E state, the symbol configuration state is the same as a symbol.
5) For symbols determined to be scheduled in one SFI (F-state symbols not between D and U), the user continues to monitor COT information, and subsequent SFIs may override the symbol state with other states. For the end symbol of the COT determined to be in the F state, the end symbol of the COT can be changed and adjusted in the subsequent SFI.
7) For a transmission configuration grant (PUSCH), PUCCH or SRS UE, a shared COT transmission may be performed on an F symbol or a U symbol determined to be unscheduled according to COT information, i.e., LBT employing Cat 2.
Example 1
Assuming that the base station performs full downlink transmission within the COT after acquiring the channel, an SFI indication is shown in fig. 3 a.
In fig. 3a, comprising 3 SFIs, the indication of the subsequent SFI may cover the F-symbol of the previous SFI indication. The second SFI as received in fig. 3a indicates a part of the F-symbols indicated by the first SFI as D-symbols, and the third SFI as received in fig. 3a may indicate all of the F-symbols indicated in the second SFI as D-symbols.
The user stops any upstream transmissions on the symbol indicated as D.
In particular implementations, the SFI may be transmitted via a multicast GC-PDCCH. In fig. 3a, black fill indicates that an SFI was received.
Example two
Assuming that the base station schedules uplink transmission within the COT after acquiring the channel, the SFI indication is shown in fig. 3 b.
In fig. 3b the F symbol is located between the D symbol and the U symbol, so the F symbol in fig. 3b can be regarded as a transition symbol, the terminal does not perform any transmission and reception in the F symbol of fig. 3 b. In fig. 3b, black fill indicates that an SFI was received.
The invention can indicate the COT information state, and the terminal can save power according to the COT information state.

According to the COT indication method, the network side equipment sends indication information for indicating the relevant information of the COT to the terminal, so that the terminal can acquire the relevant information of the COT and execute operation according to the acquired relevant information of the COT, and therefore part of unnecessary operation can be reduced, and power consumption is further reduced.
