Description

Resource indication method and related equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource indication method and a related device.

Background

In an existing Long Term Evolution (LTE) system, the following frame structure is defined for Time Division Duplex (TDD):

in the LTE TDD system, a Frame Structure Type 2 (FS 2 for short) is used, and fig. 1 shows a structural diagram of FS 2. Uplink and downlink transmissions use different subframes or different time slots on the same frequency. Each 10ms long radio frame in FS2 consists of two 5ms long half-frames, each containing 5 1ms long subframes. The subframes in FS2 are divided into three categories, which are: the subframe comprises a Downlink subframe, an Uplink subframe and special subframes, wherein each special subframe comprises a Downlink transmission Time Slot (DwPTS), a Guard Period (GP) and an Uplink transmission Time Slot (UpPTS). Each half frame comprises at least 1 downlink subframe, at least 1 uplink subframe and at most 1 special subframe. According to different uplink and downlink switching point periods and uplink and downlink allocation proportions, 7 TDD uplink and downlink configurations shown in table 1 and 10 special subframe structures shown in table 2 are defined.

Table 1: uplink and downlink configuration

TABLE 2 Special subframe configuration (DwPTS/GP/UpPTS length)

Wherein Ts is a sampling interval; x is a preconfigured or defined value.

In an LTE system, uplink and downlink resource partitioning is implemented by defining a TDD frame structure, so that an LTE cell can only configure one TDD frame structure, and only support fixed uplink and downlink resource partitioning, and is notified by system information broadcast in the cell, so that it is fixed and shared by all terminals in the cell.

In addition, in the LTE system, a GP is required between the uplink resource and the downlink resource to avoid interference between uplink and downlink in the same cell and to implement downlink-to-uplink handover. The GP exists only in the special subframe in each TDD uplink and downlink configuration, the length of the GP depends on the special subframe configuration, and one special subframe configuration corresponds to the length division of the downlink resource (DwPTS portion), uplink resource (UpPTS portion) and the GP portion in the special subframe. The special subframe configuration is also notified in a cell by the system information broadcast in the cell and is therefore fixed and not changed, and is shared by all terminals in the cell. With the development of mobile communication service demand, organizations such as ITU (International telecommunications Union) and 3GPP (3rd Generation partnership project) have started to research new wireless communication systems (e.g., 5G systems). The new wireless Communication system may support coexistence of multiple service types, for example, eMBB (Enhanced Mobile Broadband, Enhanced Mobile internet) service, URLLC (Ultra Reliable and Low Latency) service, mtc (Massive Machine Type Communication, internet of things) service, and the like, and the traffic volume of the same service may also change. In order to support different service types and flexible and variable service volume requirements, transmission structures such as a full downlink time slot, a full uplink time slot, a partial downlink time slot and a partial uplink time slot can be used, the partial downlink time slot and the partial uplink time slot can be further divided into a time slot with a main downlink and a time slot with a main uplink, and at present, how to inform that the uplink and downlink resource division in a period of time has no definite scheme.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, 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.

The core idea of the invention is as follows: and the uplink region and the downlink region in a period of time are respectively and independently notified.

In the embodiment of the present invention, as shown in fig. 2, a detailed method flow for a terminal side to obtain a resource indication is as follows:

step 201: a terminal receives first indication information, wherein the first indication information is at least used for determining an uplink region in one or more first time units after a first time unit in which the first indication information is transmitted;

step 202: the terminal receives second indication information, wherein the second indication information is at least used for determining a first time unit where the second indication information is transmitted or a downlink area in a plurality of first time units starting from the first time unit where the second indication information is transmitted.

In implementation, the terminal may receive the first indication information and/or the second indication information in each first time unit, or may receive the first indication information and/or the second indication information in a specific first time unit according to a predetermined or configured transmission period.

In a specific implementation manner, a terminal receives first indication information in a first time unit with the number i, where the first indication information is at least used to determine an uplink region in Y1 first time units starting from the first time unit with the number j after the first time unit with the number i or the first time unit with the number j, and i, j, and Y1 are integers not less than zero. At this time, the terminal may further receive the second indication information in the first time unit numbered i, and determine a downlink region among Y2 first time units starting from the first time unit numbered i or the first time unit numbered j according to the second indication information received in the first time unit numbered i.

The terminal receives second indication information in a first time unit with the number j, the second indication information is at least used for determining the first time unit with the number j or a downlink area in Y2 first time units starting from the first time unit with the number j, and j and Y2 are integers not less than zero. In this case, the terminal may further receive the first indication information in the first time unit numbered j, and determine the uplink region of Y1 first time units starting from the first time unit numbered m (m ═ j + k or m ═ i + k) mod N) or the first time unit numbered m, based on the first indication information received in the first time unit numbered j.

In an implementation, j ═ i + k, or j ═ i + k) mod N, where k and N are integers greater than or equal to 1, agreed or configured in advance.

For example, assuming that N is a cycle period of the first time unit number, it may also be referred to as the number of first time units included in a fourth time unit; for example, the number of the first time units included in one fourth time unit is agreed or configured in advance, the number of the first time units is increased from small to large in each fourth time unit, and each fourth time unit is numbered in the same numbering manner; assuming that a fourth time unit is a unit occupying D1 subframes, or D2 slots, or D3 mini-slots, or D4 symbols;

for example, assuming that N is 2, then the first time unit is 1 slot, the fourth time unit is one subframe and each subframe is assumed to include 2 slots, which means that the slot numbers are cyclically used in only one subframe, starting from 0 in the next subframe, i.e., the slot numbers in the first subframe are 0 and 1, and the slot numbers in the second subframe are 0 and 1, when i is 0 and k is 2, j is (0+2) mod2 is 0, i.e., the first indication information sent in the slot with 0 in one subframe indicates the uplink region in the slot with 0 in the next subframe;

for example, if N is 10, in this case, if the first time unit is 1 slot, the fourth time unit is one radio frame, and each radio frame is assumed to include 10 slots, the number of the slots is described to be cyclically used in only one radio frame, and the next radio frame starts from 0, that is, the slot numbers in the first radio frame are 0, 1, and … 9, and the slot numbers in the second radio frame are 0, 1, and … 9, and when i is 8 and k is 2, j is (8+2) mod10 is 0, that is, the first indication information transmitted in the slot with number of 8 in one radio frame indicates the uplink region in the slot with number of 0 in the next radio frame.

In an implementation, the first time unit is a unit that occupies a1 subframes, or a2 slots (slots), or A3 mini-slots, or a4 symbols; one of the mini-slots is a unit occupying X symbols, one slot includes one or more mini-slots, one subframe includes one or more slots, and the A1, the A2, the A3, the A4, and the X are integers greater than or equal to 1, respectively.

In an implementation, the first indication information only indicates a size and/or a position of the uplink region, where the size of the uplink region refers to the number of second time units included in the uplink region, and the position of the uplink region refers to an index of the second time units included in the uplink region; or, the first indication information indicates uplink and downlink resource division of a first time unit.

Specifically, the second time cell is predefined or configured to occupy B1 symbols, or B2 mini-slots, the B1, the B2 being integers greater than zero; one mini-slot is a unit occupying X symbols, and X is an integer greater than or equal to 1.

In an implementation, the second indication information only indicates a size and/or a position of the downlink region, where the size of the downlink region refers to the number of third time units included in the downlink region, and the position of the downlink region refers to an index of the third time units included in the downlink region; or the second indication information indicates the uplink and downlink resource division of the first time unit.

Wherein the third time cell is predefined or configured to occupy C1 symbols, or C2 mini-slots, the C1, the C2 being integers greater than zero; one mini-slot occupies X symbols in one radio frame, wherein X is an integer greater than or equal to 1. The size of the third time unit may be the same as or different from the size of the second time unit.

In implementation, the first indication information or the second indication information is carried in a higher layer signaling, or carried in a broadcast channel, or carried in a downlink control channel for transmission; and/or the first indication information and the second indication information are transmitted in the same channel or higher layer signaling or transmitted in different channels or higher layer signaling.

The first indication information and the second indication information may be carried in the same channel or configuration signaling for transmission, and are different indication fields in the channel or configuration signaling (for example, the first channel or the first configuration signaling carrying the first indication information and the second indication information is sent in each or a specific first time unit). One implementation of the terminal is as follows:

a terminal receives a first channel or a first configuration signaling in a first time unit (which may be received in each first time unit, or received in a specific first time unit according to an appointed or configured transmission cycle), where the first channel or the first configuration signaling includes first indication information and second indication information, the first indication information is at least used to determine an uplink region in one or more first time units after the first time unit in which the first channel or the first configuration signaling is transmitted, and the second indication information is at least used to determine the first channel or the first configuration signaling is transmitted or a downlink region in multiple first time units starting from the first time unit in which the first channel or the first configuration signaling is transmitted; that is, the terminal may determine, according to the first indication information in the first channel or the first configuration signaling, an uplink region in one or more first time units after the first time unit in which the first channel or the first configuration signaling is transmitted, and determine, according to the second indication information in the first channel or the first configuration information, the first time unit in which the first channel or the first configuration signaling is transmitted, or a downlink region in multiple first time units starting from the first time unit in which the first channel or the first configuration signaling is transmitted.

For example, when the terminal is to determine the uplink region in the first time unit numbered j: the terminal receives a first channel or first configuration signaling in a first time unit with the number i, wherein the first channel or the first configuration signaling comprises first indication information and second indication information, the first indication information is at least used for determining an upstream area of Y1 first time units in or starting from a first time unit with the number j after the first time unit with the number i, i and j are integers not less than zero, the second indication information is at least used for determining the first time unit with the number i or the downlink area in Y2 first time units starting from the first time unit with the number i, the terminal determines a first time unit with the number j or an uplink region in Y1 first time units starting from the first time unit with the number j according to first indication information contained in the first channel or the first configuration signaling; at this time, the terminal may further determine, according to the first channel or second indication information included in the first configuration signaling, a downlink region in the first time unit numbered i or Y2 first time units starting from the first time unit numbered i;

for another example, when the terminal is to determine the downlink region in the first time unit numbered j: a terminal receives a first channel or first configuration signaling in a first time unit with the number j, wherein the first channel or the first configuration signaling contains first indication information and second indication information, the first indication information is at least used for determining uplink regions in a first time unit with the number m (m ═ j + k or m ═ j + k) modN) after the first time unit with the number j or Y1 first time units started by the first time unit with the number m, and j and m are integers which are not less than zero, the second indication information is at least used for determining downlink regions in the first time unit with the number j or Y2 first time units started by the first time unit with the number j, and the terminal determines the first time unit with the number j or the next time unit in Y2 first time units started by the first time unit with the number j according to the second indication information contained in the first channel or the first configuration signaling A row area; at this time, the terminal may further determine, according to the first indication information included in the first channel or the first configuration signaling, the uplink region in the m-numbered first time unit or Y1 first time units starting from the m-numbered first time unit.

The first indication information and the second indication information may also be carried in different channels or configuration signaling, for example, the first indication information is carried in a first channel or a first configuration signaling, the second indication information is carried in a second channel or a second configuration signaling, the first channel or the first configuration signaling, and the second channel or the second configuration signaling may be transmitted in the same first time unit or different first time units, for example, each or a specific (determined according to the transmission cycle) first time unit sends the first channel or the first configuration signaling carrying the first indication information, and/or each or a specific first time unit sends the second channel or the second configuration signaling carrying the second indication information, for example, sends the first channel or the first configuration signaling carrying the first indication information in a part or a specific (determined according to the transmission cycle) first time unit The second channel or the second configuration signaling carrying the second indication information is sent in another part or another part of the specific first time unit. Another implementation of the terminal is as follows:

the terminal receives a first channel or a first configuration signaling in a first time unit (which may be received in each first time unit, or received in a specific first time unit according to an agreed or configured transmission cycle), the first channel or the first configuration signaling includes first indication information, the first indication information is at least used to determine an uplink region in one or more first time units after the first time unit in which the first channel or the first configuration signaling is transmitted, the terminal receives a second channel or a second configuration signaling in one first time unit (which may be received in each first time unit, or received in the specific first time unit according to the agreed or configured transmission cycle), the second channel or the second configuration signaling includes second indication information, the second indication information is at least used to determine the first time unit in which the second channel or the second configuration signaling is transmitted Or the second channel or the downlink region in the plurality of first time units starting from the first time unit where the second configuration signaling is transmitted; that is, the terminal may determine, according to the first indication information in the first channel or the first configuration signaling, an uplink region in one or more first time units after the first time unit in which the first channel or the first configuration signaling is transmitted, and determine, according to the second indication information in the second channel or the second configuration information, a downlink region in the first time unit in which the second channel or the second configuration signaling is transmitted or in a plurality of first time units starting from the first time unit in which the second channel or the second configuration signaling is transmitted.

For example, when the terminal is to determine the uplink region in the first time unit numbered j: a terminal receives a first channel or first configuration signaling in a first time unit with the number of i, wherein the first channel or the first configuration signaling contains first indication information, the first indication information is at least used for determining uplink areas of Y1 first time units in the first time unit with the number of j after the first time unit with the number of i or started by the first time unit with the number of j, and i and j are integers which are not less than zero, and the terminal determines the uplink areas of the first time unit with the number of j or the Y1 first time units started by the first time unit with the number of j according to the first indication information contained in the first channel or the first configuration signaling; at this time, the terminal may further receive a second channel or a second configuration signaling in the first time unit with the number i, where the second channel or the second configuration signaling includes second indication information, where the second indication information is at least used to determine the first time unit with the number i or a downlink region in Y2 first time units starting from the first time unit with the number i, and the terminal determines the downlink region in the first time unit with the number i or Y2 first time units starting from the first time unit with the number i according to the second indication information included in the second channel or the second configuration signaling; of course, if the first channel or the first configuration signaling is transmitted in a first time unit different from the second channel or the second configuration signaling, the first channel or the first configuration signaling and the second channel or the second configuration signaling are received in the corresponding first time unit, respectively.

For another example, when the terminal is to determine the downlink region in the first time unit numbered j: the terminal receives a second channel or second configuration signaling in a first time unit with the number j, the second indication information is at least used for determining the first time unit with the number j or a downlink region in Y2 first time units starting from the first time unit with the number j, and the terminal determines the first time unit with the number j or the downlink region in Y2 first time units starting from the first time unit with the number j according to second indication information contained in the second channel or the second configuration signaling; at this time, the terminal may further receive a first channel or first configuration signaling in a first time unit numbered j, where the first channel or the first configuration signaling includes first indication information, where the first indication information is at least used to determine uplink regions in m (m ═ j + k or m ═ j + k) modN) first time units after the first time unit numbered j or Y1 first time units started by the first time unit numbered m, where j and m are integers not less than zero, and the terminal determines uplink regions in m first time units or Y1 first time units started by the first time unit numbered m according to the first indication information included in the first channel or the first configuration signaling; of course, if the first channel or the first configuration signaling is transmitted in a first time unit different from the second channel or the second configuration signaling, the first channel or the first configuration signaling and the second channel or the second configuration signaling are received in the corresponding first time unit, respectively.

In an implementation, the first indication information or the second indication information is dedicated for the terminal, or is shared by the terminal and other terminals.

In an implementation, the uplink and downlink resource partitioning indicated by the first indication information or the second indication information specifically includes, but is not limited to, the following two cases:

firstly, the uplink and downlink resource division is specifically at least two contents of the size and/or position of a downlink region, the size and/or position of an uplink region, and the size and/or position of a guard interval of a first time unit;

and secondly, the uplink and downlink resource division is specifically an uplink and downlink structure type of the first time unit, and the uplink and downlink structure type is at least one of a full uplink structure type, a full downlink structure type and a structure type including both uplink and downlink. Wherein the structure types including both uplink and downlink further include a structure type in which uplink is dominant or downlink is dominant.

Wherein, the structure type of the full uplink refers to that all symbols in the first time unit are uplink; the structure type of full downlink means that all symbols in the first time unit are downlink; the structure type including both uplink and downlink means that part of symbols in the first time unit are uplink, part of symbols are downlink, and the rest of symbols are GP. The structure type of the upper action main means that most symbols in the first time unit are uplink; the structure type of the downlink is mainly that most symbols in the first time unit are downlink.

For example, the uplink and downlink structure type of the first time unit is predefined as one of full uplink, full downlink, or both uplink and downlink structure types. A plurality of structure types including uplink and downlink at the same time may be predefined or configured in advance, where each structure type corresponds to different uplink and downlink allocation proportions, that is, includes different numbers of uplink and downlink included in different structure types, or the uplink and downlink allocation proportions may be dynamically adjusted for the structure types including uplink and downlink at the same time, for example, the size of the GP is dynamically determined according to neighboring cell interference, Timing Advance (TA) requirements, and the like, so as to dynamically adjust the size of the uplink region and/or the downlink region.

For another example, the uplink and downlink structure types of the first time unit are predefined as follows: the method includes the steps that one of a plurality of predefined or configured structure types simultaneously including uplink and downlink is selected, wherein each structure type in the predefined or configured structure types simultaneously including uplink and downlink corresponds to different uplink and downlink allocation proportions, namely the number of different uplink and downlink symbols is included.

For another example, the uplink and downlink structure types of the first time unit are predefined as follows: one of the structure types of full uplink, full downlink, or uplink-dominated, or downlink-dominated, wherein a plurality of structure types of uplink and/or downlink-dominated may be predefined or configured, and each structure type corresponds to a different uplink and downlink allocation ratio, that is, includes different numbers of uplink symbols and downlink symbols.

In implementation, if the terminal determines that the first indication information is not received or determines that receiving the first indication information fails, the following two processing methods are not limited to be used:

first, the terminal determines not to perform uplink transmission in the first time unit corresponding to the first indication information, or determines to perform uplink transmission in the first time unit corresponding to the first indication information according to a predefined or configured time domain resource size and/or position. The first time unit corresponding to the first indication information is: and determining one or more first time units of an uplink region according to the first indication information.

Secondly, if the terminal determines that the second indication information indicates the uplink and downlink resource division of the first time unit corresponding to the first indication information, the terminal determines the uplink region of the first time unit corresponding to the first indication information according to the second indication information, and performs uplink transmission in the uplink region.

The first time unit corresponding to the first indication information is: and determining one or more first time units of an uplink region according to the first indication information, namely one or more first time units after the first time unit in which the first indication information is transmitted.

In a specific embodiment, if it is determined that the first indication information is not received in the first time unit with the number i or it is determined that the first indication information is not received in the first time unit with the number i, the terminal:

the terminal determines that uplink transmission is not performed in the first time unit numbered j or Y1 first time units starting in the first time unit numbered j, wherein the uplink transmission includes but is not limited to one or more of the following: a random access channel, an uplink control channel, an uplink shared channel, an uplink Reference Signal (such as a Sounding Reference Signal (SRS)), and the like;

or, the terminal determines that uplink transmission is performed in the first time unit numbered j or the Y1 first time units starting from the first time unit numbered j according to the predefined or configured time domain resource size and/or position, which is equivalent to that, by default, the first time unit numbered j or the Y1 first time units starting from the first time unit numbered j always include an uplink region, and if the first time unit numbered j or the Y1 first time units starting from the first time unit numbered j are full downlink symbols, the processing manner is not applicable. For example, when uplink transmission needs to be performed in the first time unit numbered j, uplink transmission is always performed in the last D1 symbols or D2 mini-slots of the first time unit numbered j, for example, uplink transmission is performed on the last 1 or 2 symbols or uplink transmission is performed in the last 1 mini-slot. Wherein the uplink transmission includes but is not limited to one or more of the following: a random access channel, an uplink control channel, an uplink shared channel, an uplink reference signal (such as SRS) and the like;

or, if the terminal determines that the second indication information indicates the uplink and downlink resource division of the j-numbered first time unit or Y2 first time units starting from the j-numbered first time unit, determining, according to the second indication information, an uplink region of the j-numbered first time unit or Y1, Y2, or min (Y1, Y2) first time units starting from the j-numbered first time unit, and performing uplink transmission in the uplink region.

In the implementation, if the terminal does not receive the second indication information or fails to receive the second indication information, the method includes, but is not limited to, the following two processing manners:

first, the terminal determines not to receive downlink transmission in the first time unit corresponding to the second indication information, or determines to receive downlink transmission in the first time unit corresponding to the second indication information according to a predefined or configured time domain resource size and/or position. Wherein, the first time unit corresponding to the second indication information is: determining one or more first time units of a downlink region according to the second indication information.

Secondly, if the terminal determines that the first indication information indicates the uplink and downlink resource division of the first time unit corresponding to the second indication information, the terminal determines the downlink region of the first time unit corresponding to the second indication information according to the first indication information, and receives downlink transmission in the downlink region.

Wherein, the first time unit corresponding to the second indication information is: determining one or more first time units of a downlink region according to the second indication information; namely, the first time unit where the second indication information is transmitted or a plurality of first time units beginning at the first time unit where the second indication information is transmitted.

In a specific embodiment, if it is determined that the second indication information is not received in the first time unit with the number j, or it is determined that the second indication information is not received in the first time unit with the number j (for example, the CRC check fails), the following processing manners are not limited to be adopted:

first, the terminal determines not to receive downlink transmission in the j-numbered first time unit or Y2 first time units starting from the j-numbered first time unit, where the downlink transmission includes but is not limited to one or more of the following: a downlink control Channel, a downlink shared Channel, a downlink Reference Signal (e.g., Common Reference Signal (CRS), Positioning Reference Signal (PRS), Channel State Information Reference Signal (CSI-RS), Demodulation Reference Signal (DMRS), etc.), and the like.

Secondly, the terminal determines that downlink transmission is received in the first time unit with the number j or the Y2 first time units starting from the first time unit with the number j according to the predefined or configured time domain resource size and/or position, at this time, it is equivalent to that the default first time unit with the number j or the Y2 first time units starting from the first time unit with the number j always include a downlink region, and if the first time unit with the number j or the Y2 first time units starting from the first time unit with the number j are all uplink structure types, the processing mode is not applicable. Wherein, the downlink transmission includes but is not limited to one or more of the following: a downlink control channel, a downlink shared channel, a downlink reference signal (such as CRS, PRS, CSI-RS, DMRS, etc.), and the like. For example, the downlink control channel is detected only in the first D3 symbols or D4 mini-slots in the first time unit numbered j. For another example, the downlink control channel is always detected in the 1 st or first 2 symbols or 1 st mini-slot in the first time unit with the number j; if the downlink control channel schedules a downlink shared channel for transmission, if the downlink control channel includes an indication field indicating the size/position of the time domain resource transmitted by the downlink shared channel, the downlink shared channel is received according to the time domain resource indicated by the indication field, and if the downlink control channel does not include an indication field indicating the size/position of the time domain resource transmitted by the downlink shared channel, the downlink shared channel is received according to the predefined or configured size and/or position of the time domain resource.

Thirdly, if the terminal determines that the first indication information indicates the uplink and downlink resource division of the j-numbered first time unit or the Y1 first time units starting from the j-numbered first time unit, determining a downlink region of the j-numbered first time unit or the Y1, the Y2 or the min (Y1, Y2) first time units starting from the j-numbered first time unit according to the first indication information, and receiving downlink transmission in the downlink region. Wherein, the downlink transmission includes but is not limited to one or more of the following: a downlink control channel, a downlink shared channel, a downlink reference signal (such as CRS, PRS, CSI-RS, DMRS, etc.), and the like. Specifically, the terminal determines, according to the first indication information, a downlink region of the first time unit, which is numbered j, and detects a downlink control channel in the downlink region, at this time, if the downlink control channel schedules a downlink shared channel transmission, if the downlink control channel includes an indication field indicating a size/position of a time domain resource of the downlink shared channel transmission, the downlink shared channel is received according to the time domain resource indicated by the indication field, and if the downlink control channel does not include an indication field indicating a size/position of a time domain resource of the downlink shared channel transmission, the downlink shared channel is received according to a size of the downlink region or a size of a region for transmitting data in the downlink region.

In an implementation, when the first indication information indicates uplink and downlink resource allocation in one or more first time units after a first time unit in which the first indication information is transmitted, for the same first time unit, if a downlink region of the first time unit determined according to the first indication information is different from a downlink region of the first time unit determined according to the second indication information, the terminal does not perform downlink transmission in the first time unit, or determines the downlink region of the first time unit based on the second indication information, or receives downlink transmission in the first time unit according to a predefined or configured time domain resource size and/or position.

In a specific embodiment, when the first indication information indicates the first time unit with the number j or the uplink and downlink resource partition of Y1 first time units starting from the first time unit with the number j, for the same first time unit, if the downlink region of the first time unit determined according to the first indication information is different from the downlink region of the first time unit determined according to the second indication information, and it is considered that the downlink region is in an incorrect configuration at this time, the terminal does not perform downlink transmission in the first time unit, or determines the downlink region of the first time unit with the second indication information as a criterion, or receives downlink transmission in the first time unit according to a predefined or configured time domain resource size and/or location. The implementation method needs to simultaneously satisfy three conditions that the terminal correctly receives the first indication information and correctly receives the second indication information, and the first indication information indicates uplink and downlink resource division in the first time unit. In this manner, the first indication information indicates uplink and downlink resource division in the first time unit, that is, the second indication information may indicate a downlink region or uplink and downlink resource division of the first time unit.

In implementation, when the second indication information indicates the first time unit in which the second indication information is transmitted or the uplink and downlink resources of a plurality of first time units starting from the first time unit in which the second indication information is transmitted are divided, for the same first time unit, if the uplink region of the first time unit determined according to the first indication information is different from the uplink region of the first time unit determined according to the second indication information, the terminal does not perform uplink transmission in the first time unit, or determines the uplink region of the first time unit based on the first indication information or the second indication information, or performs uplink transmission in the first time unit according to a predefined or configured time domain resource size and/or position.

In a specific embodiment, when the second indication information indicates the j-numbered first time unit or the uplink and downlink resource partition of Y2 first time units starting from the j-numbered first time unit, for the same first time unit, if the uplink region of the first time unit determined according to the first indication information is different from the uplink region of the first time unit determined according to the second indication information, and it is considered that the uplink region is in an error configuration at this time, the terminal does not perform uplink transmission in the first time unit, or determines the uplink region of the first time unit based on the first indication information or the second indication information, or performs uplink transmission in the first time unit according to a predefined or configured time domain resource size and/or location. The implementation method needs to simultaneously satisfy three conditions that the terminal correctly receives the first indication information and correctly receives the second indication information, and the second indication information indicates uplink and downlink resource division in the first time unit. In this manner, the second indication information indicates uplink and downlink resource division of the first time unit, that is, the first indication information may indicate an uplink region or uplink and downlink resource division of the first time unit.

In implementation, when the terminal determines that the first time unit in which the second indication information is transmitted is not the full uplink structure type according to the first indication information, the terminal receives the second indication information in the first time unit in which the second indication information is transmitted. That is, when the terminal determines that the first time unit in which the second indication information is transmitted is the full uplink structure type according to the first indication information, the terminal does not receive the second indication information in the first time unit in which the second indication information is transmitted.

In a specific embodiment, after the terminal receives the first indication information in the first time unit with the number i, if it is determined that the first time unit with the number j or the Y1 first time units starting from the first time unit with the number j are all uplink structure types according to the first indication information, the terminal may not receive the second indication information in these first time units. Therefore, as an implementation manner, the terminal may determine whether to receive the second indication information in the first time unit numbered j or Y1 first time units starting from the first time unit numbered j according to the received first indication information, so as to achieve the purpose of saving power. Specifically, after receiving the first indication information, if it is determined according to the first indication information that the first time unit numbered j or the Y1 first time units starting from the first time unit numbered j are structure types of all uplink symbols, the terminal does not receive the second indication information in the first time unit numbered j or the Y1 first time units starting from the first time unit numbered j; if it is determined according to the first indication information that the first time unit numbered j or the Y1 first time units starting from the first time unit numbered j are not all uplink structure types, receiving the second indication information at the first time unit numbered j or the Y1 first time units starting from the first time unit numbered j. Of course, the terminal may not make this determination, and always receive the second indication information in the first time unit with the number j or Y1 first time units starting from the first time unit with the number j, so as to avoid that the second indication information cannot be correctly received even when the first indication information is analyzed incorrectly.

Based on the same inventive concept, in the embodiment of the present invention, as shown in fig. 3, a detailed method flow for a base station side to perform resource indication is as follows:

step 301: a base station sends first indication information, wherein the first indication information is at least used for determining an uplink region in one or more first time units after a first time unit in which the first indication information is transmitted;

step 302: the base station sends second indication information, wherein the second indication information is at least used for determining a first time unit where the second indication information is transmitted or a downlink area in a plurality of first time units starting from the first time unit where the second indication information is transmitted.

In a specific embodiment, a base station sends first indication information in a first time unit with the number i, where the first indication information is at least used for a terminal to determine an uplink region in Y1 first time units starting from the first time unit with the number j after the first time unit with the number i or the first time unit with the number j, and i and Y1 are integers not less than zero. In this case, the base station may further transmit the second indication information in the first time cell numbered i, and the terminal may determine the first time cell numbered i or the downlink regions of Y2 first time cells starting from the first time cell numbered i, based on the second indication information received in the first time cell numbered i.

And the base station sends second indication information in the first time unit with the number j, the second indication information is at least used for the terminal to determine the first time unit with the number j or a downlink area in Y2 first time units starting from the first time unit with the number j, and j and Y2 are integers which are not less than zero. In this case, the base station may further receive the first indication information in the first time unit numbered j, and the terminal may determine the uplink region in the first time unit numbered m (m ═ j + k or m ═ i + k) mod N) or Y1 first time units starting from the first time unit numbered m, based on the first indication information received in the first time unit numbered j.

In an implementation, j ═ i + k, or j ═ i + k) mod N, where k and N are integers greater than or equal to 1, agreed or configured in advance. The explanation of N is the same as that of the terminal side, and is not described in detail.

In implementation, the first time unit occupies a1 subframes, or a2 slots, or A3 mini-slots, or a4 symbols of one radio frame; one of the mini-slots is a unit occupying X symbols, one slot includes one or more mini-slots, one subframe includes one or more slots, and the A1, the A2, the A3, the A4, and the X are integers greater than or equal to 1, respectively.

The specific implementation of the first indication information and the second indication information is the same as the description of the terminal side, and is not repeated here.

The resource indication method provided by the embodiment of the present invention is illustrated by specific embodiments.

In this embodiment, taking a slot as an example of a first time unit, assuming that a slot includes 7 symbols, OFDM symbols or SC-FDMA symbols, it should be noted that this is only an example, and certainly does not exclude the definition of first time units of other lengths:

a schematic diagram of resource indication performed by using this method is shown in fig. 4, where first indication information sent by a specific time frequency position in a first time unit is used to indicate an uplink region of a next first time unit, and second indication information sent by a specific time frequency position in a first time unit is used to indicate a downlink region in a current first time unit.

A schematic diagram of resource indication in this manner is shown in fig. 5, assuming that first indication information sent by a specific time frequency position in a first time unit is used to indicate uplink and downlink resource division in a next first time unit, and second indication information sent by a specific time frequency position in a first time unit is used to indicate a downlink region in a current first time unit.

Fig. 6 shows a schematic diagram of resource indication in this manner, assuming that first indication information sent by a specific time frequency position in a first time unit is used to indicate an uplink region in a next first time unit, and second indication information sent by a specific time frequency position in a first time unit is used to indicate uplink and downlink resource division in a current first time unit.

A schematic diagram of using this method to indicate resources is shown in fig. 7, assuming that first indication information sent by a specific time frequency position in a first time unit is used to indicate uplink and downlink resource division in a next first time unit, and second indication information sent by a specific time frequency position in a first time unit is used to indicate uplink and downlink resource division in a current first time unit.

It should be noted that, in each of the above embodiments, the first indication information indicates uplink regions or uplink and downlink resource partitions in one first time unit, and the second indication information indicates downlink regions or uplink and downlink resource partitions in one first time unit, for example, the description is performed, and if the first indication information indicates uplink regions or uplink and downlink resource partitions in a plurality of first time units, and the second indication information indicates downlink regions or uplink and downlink resource partitions in a plurality of first time units, the description is the same as the above description process, and details are not repeated here. For example, the first indication information received in the first time unit with the number i is used for determining the uplink region in the first time unit with the number j, the first time unit with the number j + n, and the first time unit with the number j + m; the second indication information received in the first time unit numbered j is used to determine the downlink region in the first time unit numbered j, the first time unit numbered j + p, and the first time unit numbered j + q. For another example, the first indication information received in the first time unit with the number i is used to determine the first time unit with the number j and the uplink region in m consecutive first time units after the first time unit with the number j; the second indication information received in the first time unit with the number j is used to determine the first time unit with the number j and an uplink region located in s consecutive first time units after the first time unit with the number j, where s may be equal to m or may not be equal to m.

When the first indication information and the second indication information are transmitted only in a part of the first time unit, the terminal only needs to detect the first indication information and the second indication information in a specific first time unit, for example, as shown in fig. 8, it is assumed that the first indication information sent by a specific time frequency position in a first time unit is used to indicate the uplink regions of the following 2 nd and 3rd first time units, the second indication information sent by a specific time frequency position in a first time unit is used to indicate the downlink regions of the 2 first time units starting from the current first time unit, the terminal only needs to detect the first indication information and the second indication information in the first time units numbered i, i +2, i +4 …, similar cases of expanding the indication modes corresponding to fig. 5, 6, and 7 to indicate a plurality of first time units are omitted for brevity.
