The title of the invention is the priority of the Chinese patent application, which is incorporated herein by reference.

Technical field

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

Background technique

The existing Long Term Evolution (LTE) system defines the following frame structure for Time Division Duplex (TDD):

The Frame Structure Type 2 (FS2) is used in the LTE TDD system. Figure 1 shows the structure of the FS2. Uplink and downlink transmissions use different subframes or different time slots on the same frequency. Each 10 ms length radio frame in FS2 consists of two 5 ms length half frames, each of which contains five 1 ms length subframes. The sub-frames in FS2 are classified into three types: downlink sub-frames, uplink sub-frames, and special sub-frames. Each special sub-frame consists of Downlink Pilot Time Slot (DwPTS) and Guard Period (Guard Period, GP) and Uplink Pilot Time Slot (UpPTS) are composed of three parts. Each field includes at least one downlink subframe and at least one uplink subframe, and at most one special subframe. According to different uplink and downlink switching point periods and uplink and downlink allocation ratios, seven kinds of TDD uplink and downlink configurations as shown in Table 1 and ten special subframe structures as shown in Table 2 are defined.

Table 1: Uplink and downlink configurations

Table 2: Special Subframe Configuration (DwPTS/GP/UpPTS Length)

Where Ts is the sampling interval; X is a pre-configured or defined value.

In the LTE system, the uplink and downlink resource partitioning is implemented by the definition of the TDD frame structure. Therefore, an LTE cell can only be configured with one TDD frame structure, and only supports fixed uplink and downlink resource partitioning, and system information broadcasted through the cell. The notification, therefore fixed, is 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 switching. The GP exists only in the special subframe in each of the TDD uplink and downlink configurations. The length of the GP depends on the special subframe configuration. A special subframe configuration corresponds to the downlink resource (DwPTS part) and the uplink in the special subframe. The length of the resource (UpPTS part) and the GP part. The special subframe configuration is also notified in a cell by the system information broadcasted in the cell, and therefore is fixed, and is shared by all terminals in the cell.

As the demand for mobile communication services changes, organizations such as the International Telecommunication Union (ITU) and the 3rd Generation Partnership Project (3GPP) are beginning to research new wireless communication systems (such as 5G systems). The new wireless communication system can support multiple service types coexisting, such as Enhanced Mobile Broadband (eMBB) services, Ultra Reliable & Low Latency Communication (URLLC) services, and massive connections. The Massive Machine Type Communication (mMTC) service, etc., will also change the business volume of the same business. In order to support different service types and flexible traffic demands, a transmission structure such as a full downlink time slot, a full uplink time slot, a partial downlink, and a partial uplink time slot may be used, and some downlink and partial uplink time slots may be further divided into The downlink-based time slot and the uplink-based time slot have no clear solution on how to notify the uplink and downlink resource allocation within a certain period of time.

The first indication information and the second indication information may also be carried in different channel or configuration signaling, for example, the first indication information is carried in the first channel or the first configuration signaling, and the second indication information is carried in 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 may be transmitted in the same first time unit or in a different first time unit, For example, the first channel or the first configuration signaling carrying the first indication information is transmitted in each first or specific (determined according to the transmission period), and/or each or a specific first time Transmitting, by the unit, the second channel or the second configuration signaling that carries the second indication information, and, for example, transmitting the first indication in the first time unit that is partially or partially specified (determined according to the transmission period) The first channel or the first configuration signaling of the information, 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 the first channel or the first configuration signaling in a first time unit (which may be received in each first time unit, or may be received in a specific first time unit according to a agreed or configured transmission period) The first channel or the first configuration signaling includes first indication information, where the first indication information is used to determine at least after the first time unit in which the first channel or the first configuration signaling is transmitted An uplink region in one or more first time units, the terminal being in a first time unit (which may be received in each of the first time units, or in a specific first time unit according to an agreed or configured transmission period) Receiving a second channel or a second configuration signaling, where the second channel or the second configuration signaling includes second indication information, where the second indication information is used to determine at least the second channel or the a first time unit in which the signaling transmission is configured or a downlink area in the plurality of first time units in which the second time channel or the first time unit in which the second configuration signaling transmission is located; that is, the terminal Determining, according to the first indication information in the first channel or the first configuration signaling, in the one or more first time units after the first time unit in which the first channel or the first configuration signaling transmission is located An uplink area, where the first time unit or the second channel or the second configuration information where the second channel or the second configuration signaling is located is determined according to the second indication information in the second channel or the second configuration information A downlink region of a plurality of first time units starting with a first time unit in which the transmission is located.

For example, when the terminal is to determine an uplink region in the first time unit numbered j: the terminal receives the first channel or the first configuration signaling in the first time unit numbered i, the first channel or the The first configuration signaling includes first indication information, where the first indication information is used to determine at least the first time unit of the number j after the first time unit of the number i or the first time numbered j An uplink area of the first time unit of the Y1, where the i, j is an integer that is not less than zero, and the terminal determines the number according to the first indication information included in the first channel or the first configuration signaling. An uplink region in the first time unit of Y, which is the first time unit of j or the first time unit numbered j; at this time, the terminal may also receive the second channel in the first time unit numbered i or The second configuration signaling, the second channel or the second configuration signaling includes second indication information, where the second indication information is used to determine at least the first time unit numbered i or the number is The first time unit of i starts a downlink area in the first time unit of the Y2, the terminal determining, according to the second indication information included in the second channel or the second configuration signaling, the first time unit numbered i or the number i a downlink area of Y2 first time units starting with a time unit; of course, if the first channel or the first configuration signaling is transmitted in a different first time unit with the second channel or the second configuration signaling, respectively Receiving the first channel or the first configuration signaling and the second channel or the second configuration signaling in the corresponding first time unit.

For another example, when the terminal is to determine the downlink area in the first time unit numbered j: the terminal receives the second channel or the second configuration signaling in the first time unit numbered j, the second indication information is at least Determining, in the Y2 first time units starting with the first time unit numbered j or the first time unit numbered j, the terminal according to the second channel or the The second indication information included in the second configuration signaling determines a downlink area in the Y2 first time units starting with the first time unit numbered j or the first time unit numbered j; in this case, the terminal may also be numbered Receiving, in a first time unit of j, a first channel or first configuration signaling, where the first channel or the first configuration signaling includes first indication information, where the first indication information is used to determine at least the number The first time unit numbered m (m=j+k or m=(j+k) mod N) after the first time unit of j or the first time unit starting from the first time unit numbered m In the uplink area in the unit, the j and m are integers not less than zero Determining, by the first channel or the first indication information included in the first configuration signaling, the first time unit numbered with m or the first time unit starting with the first time unit numbered m Uplink region; of course, if the first channel or the first configuration signaling is transmitted in a different first time unit than the second channel or the second configuration signaling, respectively, the first in the corresponding first time unit The channel or first configuration signaling is received with the second channel or the second configuration signaling.

In an implementation, the first indication information or the second indication information is exclusive to the terminal, or is shared by the terminal with other terminals.

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

First, the uplink and downlink resources are specifically divided into at least two contents of a size and/or a location of a downlink area of the first time unit, a size and/or a location of the uplink area, a size and/or a location of the guard interval;

The second uplink and downlink resource types are specifically the uplink and downlink structure types of the first time unit, and the uplink and downlink structure types are at least one of full uplink, full downlink, and uplink and downlink structure types. The structure type including the uplink and the downlink further includes an uplink-based or downlink-based structure type.

The structure type of the full uplink means that all symbols in the first time unit are uplink; the structure type of the full downlink means that all symbols in the first time unit are downlink; and the structure type including the uplink and the downlink refers to The partial symbols in the first time unit are uplink, the partial symbols are downlink, and the remaining symbols are GP. The uplink-based structure type means that most of the symbols in the first time unit are uplink; the downlink-based structure type means that most of the symbols in the first time unit are downlink.

For example, the uplink and downlink structure type of the first time unit is defined as one of full uplink, or full downlink, or one of uplink and downlink structure types. The multiple types of uplink and downlink allocations, that is, the different uplink and downlink allocation ratios, and the different uplink and downlink numbers included in different structure types, may be defined or configured in advance. Or dynamically adjust the uplink and downlink allocation ratio for the structure types including both uplink and downlink, such as dynamically determining the size of the GP according to neighbor interference, timing advance (TA) requirements, and dynamically adjusting the size of the uplink region and/or the downlink region. .

For another example, the uplink and downlink structure type of the first time unit is defined as: a plurality of pre-defined or configured ones of the plurality of structure types including the uplink and the downlink, wherein the plurality of predefined or configured ones are simultaneously Each structure type including the uplink and downlink structure types has different uplink and downlink allocation ratios, that is, the number of different uplink and downlink symbols.

For example, one of the structure types of the uplink and downlink structure of the first time unit is: full uplink, or full downlink, or uplink-based, or downlink-based, wherein multiple types may be defined or configured in advance. The behavior type of the main and/or downlink is dominant. Each structure type corresponds to different uplink and downlink allocation ratios, that is, the number of different uplink symbols and downlink symbols.

In an implementation, if the terminal determines that the first indication information is not received, or determines that the first indication information fails to be received, the terminal is not limited to the following two processing modes:

First, the terminal determines that the first time unit corresponding to the first indication information does not perform uplink transmission, or determines that the first time unit corresponding to the first indication information is pre-defined or configured. The domain resource size and/or location is uplinked. The first time unit corresponding to the first indication information is: determining one or more first time units of the uplink area according to the first indication information.

The second 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, and determines that the first indication information corresponds to the second indication information. The uplink area of the first time unit is uplinked in the uplink area.

The first time unit corresponding to the first indication information is: determining one or more first time units of the uplink area according to the first indication information, that is, where the first indication information is transmitted One or more first time units after a time unit.

In a specific implementation, the terminal determines that the first indication information is not received in the first time unit of the number i, or determines that the first time unit in the number i is received. If the first indication fails, then:

The terminal determines that the Y1 first time units starting with the first time unit numbered j or the first time unit numbered j are not performing uplink transmission, where the uplink transmission includes but is not limited to the following content. One or more of: a random access channel, an uplink control channel, an uplink shared channel, an uplink reference signal (such as a Sounding Reference Signal (SRS), etc.);

Alternatively, the terminal determines that the Y1 first time units starting with the first time unit numbered j or the first time unit numbered j are uplinked according to a predefined or configured time domain resource size and/or location. The transmission, which is equivalent to the first time unit numbered j or the first time unit starting from the first time unit numbered j, always includes the uplink area, if the number is the first time of j The processing mode is not applicable if the unit or the first time unit of the first time unit numbered j is the full downlink symbol. For example, when uplink transmission is required in the first time unit numbered j, uplink transmission is always performed in the last D1 symbol or D2 mini-slot of the first time unit numbered j, for example, last Uplink transmission is performed on one or two symbols or in the last one mini-slot. 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, etc.);

Or, if the terminal determines that the second indication information indicates the first time unit of the number j or the Y2 first time units of the first time unit that is numbered j, according to the uplink and downlink resource division, according to the terminal, according to Determining, by the second indication information, an uplink area of the first time unit of the number j or the first time unit of the first time unit of the number j, or Y1 or Y2 or min (Y1, Y2) Uplink transmission is performed in the uplink area.

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

The time domain resource size and/or location receives the downlink transmission. The first time unit corresponding to the second indication information is: determining one or more first time units of the downlink area according to the second indication information.

The second 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, and determines, according to the first indication information, that the second indication information corresponds to a downlink area of the first time unit, in which downlink transmission is received.

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.). 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 example, the downlink control channel is always detected on the first or first two symbols in the first time unit of the number j, or in the first mini-slot; if the downlink control channel schedules a downlink a shared channel transmission, if the downlink control channel includes an indication field indicating a time domain resource size/location of the downlink shared channel transmission, receiving the downlink shared channel according to the time domain resource indicated by the indication domain, if the downlink control The channel does not include an indication field indicating the time domain resource size/location of the downlink shared channel transmission, and the downlink shared channel is received according to the predefined or configured time domain resource size and/or location.

In an implementation, when the first indication information indicates uplink/downlink resource partitioning in one or more first time units after the first time unit in which the first indication information transmission is located, for the same first time unit, If the downlink area of the first time unit determined by the terminal according to the first indication information is different from the downlink area of the first time unit determined according to the second indication information, then the first The downlink unit is not performed in the time unit, or the downlink area of the first time unit is determined according to the second indication information, or the time domain resource size and the predefined or configured time in the first time unit are / or location to receive downlink transmissions.
