Description

Method and device for indicating micro time slot

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for indicating a micro timeslot.

Background

With the rapid development of mobile services, the current wireless communication technology, such as the fourth generation mobile communication technology featuring Orthogonal Frequency Division Multiplexing (OFDM), cannot meet the requirements of new scenarios. Research on the fifth-Generation mobile communication technology (5th-Generation, 5G) has been vigorously conducted in both academic and industrial fields.

The fifth generation mobile communication technology needs to support ultra-high data transmission rate, massive connection number and low data transmission delay to meet the requirements of different scenes. For different scenario requirements, a variety of different numerologies may be introduced in the New 5G Radio (NR), and the subcarrier spacing, symbol length, subframe length, etc. may be different in different numerologies. The current 5G communication main scenes include the following three types: enhanced Mobile BroadBand (eMBB), massive Machine Type Communications (mMTC), and high-reliability Low-Latency (Ultra-Reliable and Low Latency Communications, URLLC). The three scenarios are different in the types of services and the requirements. For example, the eMBB is mainly for a service scenario requiring a higher data rate, and two main indicators of the eMBB service are high bandwidth and low latency. In future high frequency communication, a large bandwidth of 100MHz may be supported, and it is likely that the entire bandwidth is directly allocated to one user at a time. The uplink scheduling delay and the Hybrid Automatic Repeat reQuest (HARQ) feedback delay also bring about delay effects. The mMTC service mainly aims at a large number of connected service scenes, needs narrow-band service, has long service life of a battery, and has frequency domain with smaller granularity and time domain resources with wider granularity. For URLLC service, it mainly aims at service scenarios with high delay requirement and reliability. For URLLC traffic, 3GPP (3rd Generation Partnership Project) introduces mini-slots (mini-slots) in order to further reduce latency. A micro slot is a slot of a small size, which is not a full length slot. Compared to the current slot concept (same subcarrier spacing), it is shorter in duration.

Currently, the agreed upon micro-slot generally means that the number of symbols supported by the micro-slot is less than the number of symbols of one slot, the micro-slot may include a control signal, the minimum unit included in the micro-slot is the smallest possible scheduling unit, a Downlink Control Information (DCI) indication, and the like.

The structure of the micro-slot, the number of symbols supported by the micro-slot, and the Physical Downlink Control Information (PDCCH) monitoring mode of the micro-slot all need to be clearly defined, and the User Equipment (UE) cannot determine the micro-slot and cannot use the micro-slot. The current 5G NR discussion introduces a micro slot, how to indicate the micro slot and the structure of the micro slot are technical problems to be solved currently.

Description of the main elements

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

In the embodiments of the present invention, a user equipment may also be referred to as a terminal, and the user equipment communicates with a base station. The user equipment is a device capable of automatically performing numerical calculation and/or information processing according to a preset or stored instruction, and the hardware includes, but is not limited to, a microprocessor, an Application Specific Integrated Circuit (ASIC), a Programmable Gate Array (FPGA), a Digital Signal Processor (DSP), an embedded device, and the like.

The user equipment includes, but is not limited to, any electronic product capable of performing human-computer interaction with a user through a keyboard, a mouse, a remote controller, a touch panel, or a voice control device, for example, a Personal computer, a tablet computer, a smart phone, a Personal Digital Assistant (PDA), an interactive Internet Protocol Television (IPTV), a smart wearable device, a Digital camera, and the like. The user equipment mentioned above is only an example, not an exhaustive list, and includes but is not limited to the user equipment mentioned above.

To better illustrate the specific implementation of the embodiments of the present invention, the definition of a mini-slot is explained. The current New Radio technology (NR) of the fifth Generation mobile communication technology (5th-Generation, 5G) provides a definition of a micro slot, i.e. the micro slot is only smaller than one slot (slot). When the number of symbols of a slot is N, the length of a micro-slot (i.e., the number of symbols included in the micro-slot) may take any integer ranging from 1 to N-1. As shown in fig. 1, taking the number of 14 symbols in a timeslot as an example, the length of a micro slot may be any integer between 1 symbol and 13 symbols, and the range of the starting position of the micro slot may also be the position of any one symbol in the 14 symbols.

Fig. 2 is a flow chart of a first preferred embodiment of the indication of the minislots according to the present invention. The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs.

S10, the base station determines the indication information of the micro time slot, wherein the indication information of the micro time slot comprises the configuration information of the micro time slot and the control information of the micro time slot.

In at least one embodiment of the present invention, the configuration information of the micro-slot includes, but is not limited to, one or more of the following: the starting position of the micro slot, the length of the micro slot, etc., and of course, the configuration information of the micro slot may also include other time domain resources of the micro slot, etc. The control information of the micro-slot includes, but is not limited to, one or more of the following: downlink Control Information (DCI) scheduling information of a micro slot, Physical Downlink Shared Channel (PDSCH) scheduling control of a micro slot, Physical Uplink Shared Channel (PUSCH) scheduling control of a micro slot, and the like. The base station informs the user equipment of the configuration information of the micro time slot and the control information of the micro time slot, and the user equipment can use the micro time slot after knowing the configuration information of the micro time slot and the control information of the micro time slot.

In at least one embodiment of the present invention, the base station may not limit the starting position of the micro slot. The micro-slot may have multiple transmission positions that may not overlap and the starting position of the micro-slot may be at least one of the multiple transmission positions. For example, as shown in fig. 1, taking a slot with a length of 14 symbols as an example, assuming that the length of a micro slot is 2 symbols, any two consecutive symbols from numbers 0 to 13 can form a micro slot, and the micro slot has a maximum of 7 possible starting positions.

In other embodiments, the plurality of transmission positions may overlap, the starting position of the micro-slot may be at least one of the plurality of transmission positions, and the number of starting positions of the micro-slot is N-N +1, where N represents the number of symbols of a slot and N represents the length of the micro-slot. As shown in fig. 1, taking a slot with a length of 14 symbols as an example, it is assumed that the position where the micro slot has a length of 2 symbols, i.e. the symbols with numbers 0 to 12, are located may be the starting position of the micro slot.

Preferably, the method for indicating a micro slot further includes: setting the starting position of the micro time slot and/or the length of the micro time slot. The setting of the starting position of the micro-slot comprises one or more of the following:

(1) in at least one embodiment of the present invention, the base station sets the start position of the micro slot in the slot according to the traffic demand. Preferably, the base station may further preset a starting position number of the micro slot, where the starting position number of the micro slot is a positive integer.

The business requirements include, but are not limited to: latency requirements, and the like. For example, a user with a high delay requirement may set a larger number of start positions of the micro slots, and a user with a low delay requirement may set a smaller number of start positions of the micro slots.

For example, in one timeslot, the number of start positions of a micro timeslot is set to two, that is, a first start position of the micro timeslot and a second start position of the micro timeslot, where the first start position of the micro timeslot is at the start position of the timeslot, and the second start position of the micro timeslot is at a middle position of the timeslot, and the length of the micro timeslot may be determined according to traffic demands. The minislots may be used for high-reliability Low-Latency Communications (URLLC) traffic, enhanced Mobile BroadBand (eMBB) traffic of a small packet, and a device on an unlicensed band using a remaining slot resource after occupying a channel in one slot.

(2) In at least one embodiment of the present invention, the base station sets the start position of the micro slot in the slot according to the sub-carrier.

Further, the base station sets the starting position number of the micro time slot according to the interval of the sub-carriers.

The larger the subcarrier spacing, the fewer the number of starting positions of a minislot within a slot. Therefore, if the service type is URLLC service, the base station can correspondingly adjust the number of start positions of the micro slots in a time slot according to different subcarrier intervals, for example, set a start position, etc., and if the micro slots are used in an unauthorized frequency band, the start positions of a plurality of micro slots can be set as needed without considering different subcarrier intervals, so as to improve the spectrum efficiency.

(3) In at least one embodiment of the present invention, the base station sets the start position of the micro slot based on an uplink and downlink process.

Further, in the Downlink process, the base station reduces the number of start positions of the micro slots to reduce the number of times that the ue monitors a Physical Downlink Control Channel (PDCCH) when the service requirement (e.g., delay requirement, eMBB service of a packet) is met, and/or in the uplink process, if the uplink employs an uplink free scheduling (UL-grant free) to transmit data, the base station divides the ue into groups of a predetermined number, where each group corresponds to one start position.

S11, the base station sends the indication information of the micro time slot to the user equipment based on the indication mode so that the user equipment can acquire the configuration information of the micro time slot and the control information of the micro time slot.

In at least one embodiment of the present invention, the indication means includes, but is not limited to, one or more of the following: a first-level indication mode and a second-level indication mode. The first-level indication mode is to indicate the indication information of the micro-slot to the user equipment all at once, and the user equipment can use the micro-slot to receive and transmit data according to the indication information of the micro-slot after receiving the indication information of the micro-slot.

The two-stage indication mode divides the indication information of the micro-slot into two parts for indication, namely, the indication information of the micro-slot is divided into a first part of indication information and a second part of indication information. And after receiving the first part of indication information and the second part of indication information, the user equipment forms the first part of indication information and the second part of indication information into the indication information of the micro-slot, so that the user equipment can use the indication information of the micro-slot to receive and transmit data. Compared with the first-level indication mode, the second-level indication mode can reduce the granularity of the control information of the user equipment for monitoring the micro time slot.

The first part indication information comprises one or more of the following: configuration information of the micro slot (such as a starting position of the micro slot, a length of the micro slot), whether the user equipment needs to use the micro slot in the slot, a position of the remaining indication information, and the like. The second part indication information includes, but is not limited to: the remaining indication information. The remaining indication information is indication information other than the first part indication information of the micro slot among the indication information of the micro slot.

In at least one embodiment of the present invention, in the primary indication mode, the indication information of the micro slot is located at the boundary of each slot, that is, within the symbol of the starting position of each slot. At this time, the micro-slot may be used only for transmitting data, and the indication information of the micro-slot does not transmit an applicable scenario, such as enhanced Mobile BroadBand (eMBB) service of a packet, inside the micro-slot. Of course, in other embodiments, the minislots may not be limited to use only for transmitting data.

In at least one embodiment of the present invention, in the primary indication manner, the indication information of the micro slot is located in a symbol of a start position of each micro slot, that is, the ue needs to detect whether there is control information of a needed micro slot at the start position of each micro slot. When the length of the micro slot and the start position of the micro slot are not limited, that is, the length of the micro slot and the start position of the micro slot are flexibly set, the ue needs to monitor the control information of the micro slot at the possible start position (i.e., the plurality of transmitting positions) of each micro slot in a slot, which increases the implementation complexity of the ue and the battery consumption of the ue.

Preferably, the base station may preset the length of the micro timeslot and/or the starting position of the micro timeslot to reduce the number of times that the ue listens to the indication information of the micro timeslot, for example, according to the setting of the starting position of the micro timeslot in S10, but may also preset according to other setting conditions. And the user equipment determines the resource position (namely the time frequency position or the time frequency resource) of the control information of the micro time slot, which the user equipment needs to monitor, according to the length of the micro time slot and/or the initial position of the micro time slot. When the user equipment determines the resource position of the control information of the micro time slot, which the user equipment needs to monitor, according to the length of the micro time slot, the user equipment also needs to determine the resource position of the control information of the micro time slot, which the user equipment needs to monitor, by combining with the setting rule of the starting position of the micro time slot. For example, the setting rules include, but are not limited to: the plurality of transmission positions of the minislots may not overlap, the plurality of transmission positions of the minislots may overlap, and so on. The indication mode is suitable for a scene such as high-reliability and Low Latency Communications (URLLC) service.

For example, the number of symbols of one timeslot is N, the base station configures the length of the micro timeslot as M according to needs, the number of start positions of the micro timeslot is T, and the desirable range of M is any integer between 1 and N-1. Then the user equipment may listen for the indication information at the start of each micro-slot in one time slot.

In at least one embodiment of the present invention, in the two-stage indication mode, the first part of indication information is located in a symbol of a starting position of a timeslot, the second part of indication information is located inside a micro timeslot, and preferably, the second part of indication information is located in a symbol of a starting position of a micro timeslot. The first part of indication information is used for indicating whether the user equipment needs to use the micro-slot and indicating the configuration information of the micro-slot, so that the user equipment can quickly monitor the control information of the needed micro-slot.

In at least one embodiment of the present invention, in the two-stage indication mode, both the first part of indication information and the second part of indication information are located inside the micro slot.

Preferably, the method for indicating a micro slot further includes: the base station sets the resource position of the first part of the indication information in advance, that is, the base station sets a fixed resource position to indicate the first part of the indication information. Therefore, the UE can monitor the first part of the indication information at a fixed resource location each time, and then monitor the second part of the indication information according to the first part of the indication information. If the starting position of the micro slot and the length of the micro slot are not limited in one slot, the starting position of the micro slot may be many, which may increase the complexity of the ue and decrease the spectrum utilization efficiency.

Fig. 3 is a flow chart of the indication of the minislots according to the second preferred embodiment of the present invention. The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs.

And S20, the user equipment receives the indication information of the micro time slot sent by the base station based on the indication mode.

In at least one embodiment of the present invention, the base station sends the indication information of the micro slot to the user equipment based on the indication mode.

The indication means includes, but is not limited to, one or more of the following: a first-level indication mode and a second-level indication mode. The first-level indication mode is to indicate the indication information of the micro-slot to the user equipment all at once, and the user equipment can use the micro-slot to receive and transmit data according to the indication information of the micro-slot after receiving the indication information of the micro-slot.

The two-stage indication mode divides the indication information of the micro-slot into two parts for indication, namely, the indication information of the micro-slot is divided into a first part of indication information and a second part of indication information. And after receiving the first part of indication information and the second part of indication information, the user equipment forms the indication information of the micro-slot by the first part of indication information and the second part of indication information, so that the user equipment can use the micro-slot to receive and transmit data.

The first part indication information includes basic information of the micro-slot, which includes, but is not limited to, one or more of the following: configuration information of the micro slot (such as a starting position of the micro slot, a length of the micro slot), whether the user equipment needs to use the micro slot in the slot, a position of the remaining indication information, and the like. The second part indication information includes, but is not limited to: the remaining indication information. The remaining indication information is indication information other than the basic information of the micro slot among the indication information of the micro slot. The configuration information of the micro-slot includes, but is not limited to, one or more of the following: the starting location of the micro-slot, the length of the micro-slot, etc.

In at least one embodiment of the present invention, in the primary indication manner, the indication information of the micro slot may be located in a symbol of a start position of each slot. In other embodiments, the indication information of the micro slot may also be located in the symbol of the starting position of each micro slot.

In at least one embodiment of the present invention, in the two-level indication manner, the first part of the indication information may be located in a symbol of a start position of a timeslot, and the second part of the indication information is located inside a micro timeslot. In other embodiments, the first part of indication information and the second part of indication information may be both located inside the micro slot.

And S21, the user equipment acquires the configuration information of the micro time slot and the control information of the micro time slot according to the indication information of the micro time slot.

In at least one embodiment of the present invention, when the base station indicates the indication information of the micro slot to the ue at one time based on the primary indication manner, and the indication information of the micro slot is located in a symbol of a starting position of each time slot, the ue monitors the indication information of the micro slot at the starting position of each time slot, and obtains configuration information of the micro slot and control information of the micro slot.

And when the base station indicates the indication information of the micro time slot to the user equipment at one time based on the primary indication mode and the indication information of the micro time slot is positioned in the symbol of the initial position of each micro time slot, the user equipment monitors the indication information of the micro time slot at the initial position of each micro time slot and acquires the configuration information of the micro time slot and the control information of the micro time slot.

When the start position of the micro slot is not preset, the ue needs to listen to the control information of the micro slot at the possible start position (i.e. the plurality of transmission positions) of each micro slot in a slot.

And when the starting position of the micro time slot is preset by the base station, the user equipment determines the resource position of the control information of the micro time slot, which the user equipment needs to monitor, according to the length of the micro time slot and/or the starting position of the micro time slot. When the user equipment determines the resource position of the control information of the micro time slot, which the user equipment needs to monitor, according to the length of the micro time slot, the user equipment also needs to determine the resource position of the control information of the micro time slot, which the user equipment needs to monitor, by combining with the setting rule of the starting position of the micro time slot. For example, the setting rules include, but are not limited to: multiple transmission positions of the minislots do not overlap, multiple transmission positions of the minislots can overlap, and so on.

In at least one embodiment of the present invention, when the base station sends the indication information of the micro timeslot to the ue based on the secondary indication manner, the ue first monitors the first part of the indication information, determines whether the micro timeslot is needed to be used in the timeslot according to the first part of the indication information, and determines a resource location of control information that needs to monitor the micro timeslot according to configuration information of the micro timeslot in the first part of the indication information when the micro timeslot is needed to be used in the timeslot.

Preferably, if the base station sets the resource location of the first part of the indication information in advance, that is, the base station sets the fixed resource location to indicate the first part of the indication information, the ue monitors the first part of the indication information at the preset resource location, and then monitors the second part of the indication information according to the first part of the indication information.

And S22, the user equipment receives and transmits data according to the configuration information of the micro time slot and the control information of the micro time slot.

In the invention, a base station determines the indication information of a micro-slot, wherein the indication information of the micro-slot comprises the configuration information of the micro-slot and the control information of the micro-slot; and the base station sends the indication information of the micro time slot to user equipment based on an indication mode so that the user equipment acquires the configuration information of the micro time slot and the control information of the micro time slot. The user equipment receives indication information of the micro time slot sent by the base station based on the indication mode; the user equipment acquires the configuration information of the micro-slot and the control information of the micro-slot according to the indication information of the micro-slot; and the user equipment receives and transmits data according to the configuration information of the micro time slot and the control information of the micro time slot. The invention can adopt different indication modes to send the indication information of the micro time slot to the user equipment so as to meet different service requirements, thereby reducing the complexity of the user equipment and improving the spectrum use efficiency.

Fig. 4 is a functional block diagram of a first preferred embodiment of the apparatus for indicating minislots according to the present invention. The indication device 11 of the micro-slot includes a determining module 100, a setting module 101 and a sending module 102. The module referred to in the present invention refers to a series of computer program segments that can be executed by a processing device of the base station and that can perform a fixed function, and that are stored in a memory device of the base station. In the present embodiment, the functions of the modules will be described in detail in the following embodiments.

The determining module 100 determines indication information of a micro slot, where the indication information of the micro slot includes configuration information of the micro slot and control information of the micro slot.

In at least one embodiment of the present invention, the determining module 100 may not limit the starting position of the micro slot. The micro-slot may have multiple transmission positions that may not overlap and the starting position of the micro-slot may be at least one of the multiple transmission positions. For example, as shown in fig. 1, taking a slot with a length of 14 symbols as an example, assuming that the length of a micro slot is 2 symbols, any two consecutive symbols from numbers 0 to 13 can form a micro slot, and the micro slot has a maximum of 7 possible starting positions.

Preferably, the indication device of the micro slot further includes: the setting module 102 sets a start position of the micro slot and/or a length of the micro slot. The setting of the starting position of the micro-slot comprises one or more of the following:

(1) in at least one embodiment of the present invention, the setting module 101 sets a starting position of the micro timeslot in a timeslot according to a service requirement. Preferably, the setting module 101 may further preset a starting position number of the micro slot, where the starting position number of the micro slot is a positive integer.

For example, the setting module 101 sets the number of the start positions of the micro slots to two in one time slot, that is, sets a first start position of the micro slot and a second start position of the micro slot, where the first start position of the micro slot is at the start position of the time slot, and the second start position of the micro slot is at the middle position of the time slot, and the length of the micro slot may be determined according to the service requirement. The minislots may be used for high-reliability Low-Latency Communications (URLLC) traffic, enhanced Mobile BroadBand (eMBB) traffic of a small packet, and a device on an unlicensed band using a remaining slot resource after occupying a channel in one slot.

(2) In at least one embodiment of the present invention, the setting module 101 sets the start position of the micro slot in the slot according to the sub carrier.

Further, the setting module 101 sets the starting position number of the micro slot according to the interval of the sub carriers.

The larger the subcarrier spacing, the fewer the number of starting positions of a minislot within a slot. Therefore, if the service type is the URLLC service, the setting module 101 may correspondingly adjust the starting position number of the micro slots in one time slot according to different subcarrier intervals, for example, set a starting position, and if the micro slots are used in an unauthorized frequency band, the starting positions of a plurality of micro slots may be set as needed, without considering different subcarrier intervals, so as to improve the spectrum efficiency.

(3) In at least one embodiment of the present invention, the setting module 101 sets the start position of the micro timeslot based on an uplink and downlink process.

Further, in the Downlink process, the setting module 101 reduces the number of start positions of the micro timeslot to reduce the number of times that the ue monitors a Physical Downlink Control Channel (PDCCH) when meeting a service requirement (e.g., a delay requirement, an eMBB service of a packet). In the uplink process, if uplink scheduling free (UL-grant free) is used for transmitting data, the setting module 101 divides the ue into a preset number of groups, where each group corresponds to an initial position.

The sending module 102 sends the indication information of the micro slot to the user equipment based on the indication mode so that the user equipment obtains the configuration information of the micro slot and the control information of the micro slot.

Preferably, the setting module 101 may preset the length of the micro timeslot and/or the starting position of the micro timeslot to reduce the number of times that the ue monitors the indication information of the micro timeslot, for example, the setting module 101 sets the starting position of the micro timeslot according to the above embodiment, and may also preset according to other setting conditions. And the user equipment determines the resource position of the control information of the micro time slot which needs to be monitored by the user equipment according to the length of the micro time slot and/or the initial position of the micro time slot. When the user equipment determines the resource position of the control information of the micro time slot, which the user equipment needs to monitor, according to the length of the micro time slot, the user equipment also needs to determine the resource position of the control information of the micro time slot, which the user equipment needs to monitor, by combining with the setting rule of the starting position of the micro time slot. For example, the setting rules include, but are not limited to: the plurality of transmission positions of the minislots may not overlap, the plurality of transmission positions of the minislots may overlap, and so on. The indication mode is suitable for a scene such as high-reliability and Low Latency Communications (URLLC) service.

Preferably, the setting module 101 sets the resource location of the first part of indication information in advance, that is, the setting module 101 sets a fixed resource location to indicate the first part of indication information. Therefore, the UE can monitor the first part of the indication information at a fixed resource location each time, and then monitor the second part of the indication information according to the first part of the indication information. If the starting position of the micro slot and the length of the micro slot are not limited in one slot, the starting position of the micro slot may be many, which may increase the complexity of the ue and decrease the spectrum utilization efficiency.

Fig. 5 is a functional block diagram of a second preferred embodiment of the apparatus for indicating minislots according to the present invention. The indication device 21 of the micro timeslot includes a receiving module 200, an obtaining module 201, and a transceiver module 202.

The indication means includes, but is not limited to, one or more of the following: a first-level indication mode and a second-level indication mode. The first-level indication mode is to indicate the indication information of the micro timeslot to the user equipment all at once, and after the receiving module 200 receives the indication information of the micro timeslot, the transceiver module 202 may use the micro timeslot to transmit and receive data according to the indication information of the micro timeslot.

The two-stage indication mode divides the indication information of the micro-slot into two parts for indication, namely, the indication information of the micro-slot is divided into a first part of indication information and a second part of indication information. After the receiving module 200 receives the first part of the indication information and the second part of the indication information, the obtaining module 201 forms the first part of the indication information and the second part of the indication information into the indication information of the micro-slot, so that the ue can use the micro-slot to receive and transmit data.

The first part indication information includes basic information of the micro-slot, which includes, but is not limited to, one or more of the following: configuration information of the micro slot (such as a starting position of the micro slot, a length of the micro slot), whether the user equipment needs to use the micro slot in the slot, a position of the remaining indication information, and the like.

Preferably, when the start position of the micro slot is not preset, and when the start position of the micro slot is not preset, the obtaining module 201 needs to monitor the control information of the micro slot at a possible start position (i.e. the plurality of sending positions) of each micro slot in a time slot.

Preferably, when the starting position of the micro slot is preset by the base station, the obtaining module 201 determines a resource location where the ue needs to monitor the control information of the micro slot according to the length of the micro slot and/or the starting position of the micro slot.

When the obtaining module 201 determines the resource location of the control information that the ue needs to monitor the micro-slot according to the length of the micro-slot, the obtaining module 201 also needs to determine the resource location of the control information that the ue needs to monitor the micro-slot by combining with the setting rule of the start position of the micro-slot. For example, the setting rules include, but are not limited to: multiple transmission positions of the minislots do not overlap, multiple transmission positions of the minislots can overlap, and so on.

In at least one embodiment of the present invention, when the base station sends the indication information of the micro timeslot to the ue based on the secondary indication manner, the obtaining module 201 first monitors the first part of the indication information, and determines whether the micro timeslot is needed to be used in the time slot according to the first part of the indication information, and when the micro timeslot is needed to be used in the time slot, the obtaining module 201 determines a resource location of the control information that needs to monitor the micro timeslot according to the configuration information of the micro timeslot in the first part of the indication information.

Preferably, if the base station sets the resource location of the first part of the indication information in advance, that is, the base station sets the fixed resource location to indicate the first part of the indication information, the obtaining module 201 monitors the first part of the indication information at the preset resource location, and then monitors the second part of the indication information according to the first part of the indication information.

The transceiver module 202 is configured to transmit and receive data according to the configuration information of the micro-slot and the control information of the micro-slot.

In the invention, a base station determines the indication information of a micro-slot, wherein the indication information of the micro-slot comprises the configuration information of the micro-slot and the control information of the micro-slot; and the base station sends the indication information of the micro time slot to user equipment based on an indication mode so that the user equipment acquires the configuration information of the micro time slot and the control information of the micro time slot.
