Description

Information transmission method and device

The invention belongs to the field of communication technologies, and in particular relates to an information transmission method and device.

As the demand for mobile communication services changes, organizations such as the ITU (International Telecommunication Union) and 3GPP have begun to research new wireless communication systems, such as 5G systems. The new wireless communication system can support multiple service types, such as Ultra-Reliable and Low-Latency Communication (URLLC) services, Enhanced Mobile Broadband (eMBB) services, and oversized connected machines. Massive Machine Type Communication (mMTC) business, etc.; and the business volume of the same business will also change.

In the existing Long Term Evolution (LTE) system, seven types of TDD UL/DL (uplink/downlink) configurations are defined for Time Division Duplex (TDD), as shown in Table 1.

In the LTE TDD system, each 10ms radio frame is composed of two 5ms half frames, and each half frame contains five subframes of 1 ms length. The sub-frames in a radio frame can be divided into three categories: a downlink sub-frame, an uplink sub-frame, and a special sub-frame. Each special sub-frame is composed of DwPTS (Downlink Pilot Time Slot). The GP (Guard Period) and the UpPTS (Uplink Pilot Time Slot) are composed of three parts. Each semi-frame contains at least one downlink subframe and at least one uplink subframe, and at most one special subframe.

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 a TDD frame structure, and only supports fixed uplink and downlink resource partitioning, and broadcasts through the cell. The system information is notified, so the uplink and downlink resources are fixed.

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 subframes in each of the above TDD uplink and downlink configurations. The length of the GP depends on the special subframe configuration. A special subframe configuration corresponds to the DwPTS and UpPTS in the special subframe. The length of the GP is divided. The configuration of the special subframe is also notified by the system information broadcasted in the cell in one cell, so the configuration of the special subframe is also fixed.

As shown in FIG. 2, the method includes the following steps: Step 201: The terminal receives the indication information sent by the network device, where the indication information is used by the terminal to determine an uplink area in a time unit where the uplink shared channel is transmitted. Step 202: The terminal sends an uplink shared channel in the uplink area.

In the embodiment of the present invention, the terminal receives the indication information sent by the network device, and determines the transmission resource of the uplink shared channel according to the indication information, so as to ensure the correct transmission of the uplink shared channel.

The uplink shared channel in the embodiment of the present invention may be an uplink shared channel without corresponding scheduling signaling, and specifically includes one or more of the following: an unscheduled uplink shared channel; a semi-persistently scheduled uplink shared channel; and a physical hybrid automatic retransmission indication. The channel (Physical Hybrid ARQ Indicator Channel, PHICH) triggers the uplink shared channel of the retransmission.

The uplink unscheduled transmission means that the uplink transmission of the terminal does not require network side dynamic and explicit scheduling signaling for scheduling, and multiple terminals can share the same time domain and/or frequency domain resources; at this time, the time domain can be specified or not specified. The transmission period or the time domain transmission time, if not specified, when the terminal has uplink data to be transmitted, it can select a time zone and/or a frequency domain configured for the terminal in any time unit including the uplink area. Uplink transmission on the resource.

The time unit is defined as D1 subframes, or D2 slots, or D3 mini-slots, or D4 symbols, where D1, D2, D3, and D4 are integers greater than or equal to 1.

Specifically, in step 201, the terminal may receive the indication information in a time unit in which the uplink shared channel is transmitted or in a time unit before the time unit in which the uplink shared channel is transmitted. That is, the network device may send the indication information at a specific time-frequency position in the time unit in which the uplink shared channel transmission is located, or the network device may also be specific in the time unit before the time unit in which the uplink shared channel is transmitted. The indication information is sent at the time-frequency position.

The indication information may be high layer signaling, or carried in a broadcast channel, or carried in a downlink control channel. The downlink control channel may be a downlink control channel using an uplink DCI format or a downlink control channel using a downlink DCI format or a downlink control channel using a DCI format dedicated to carrying indication information. The indication information is exclusive to the terminal or shared by the terminal.

The indication information may indicate a time domain size and/or a time domain location of an uplink region in a time unit in which the uplink shared channel is transmitted.

The indication information may also indicate uplink and downlink resource division of the time unit in which the uplink shared channel is transmitted. The uplink and downlink resources are specifically configured as: at least two of the downlink resource, the uplink resource, and the protection interval GP resource, where the downlink resource includes a size and/or a location of the downlink area, and the uplink resource includes an uplink area. And/or location, the GP resource includes a size and/or a location of the GP; or the indication information indicates an uplink and downlink structure type of a time unit in which the uplink shared channel is transmitted, and the uplink and downlink structure type is full uplink, full downlink, At the same time, at least one of the uplink and downlink structure types is included.

The full uplink means that all the symbols in the time unit are uplink; the full downlink means that all symbols in the time unit are downlink; and the uplink and the downlink include the partial symbols in the time unit. Upstream, some symbols are down and the remaining symbols are GP.

The structure types including the uplink and the downlink may be further classified into a structure type in which the uplink is dominant (that is, most of the symbols in the time unit are uplink) or the downlink is dominant (that is, most of the symbols in the time unit are downlink).

For example, the indication information indicates that the time unit is one of full uplink or full downlink or both uplink and downlink structure types; wherein, multiple types of structures including uplink and downlink may be pre-defined or configured, and each The structure type corresponds to different uplink and downlink allocation ratios (that is, the number of different uplink and downlink symbols), or the uplink and downlink allocation ratio can be dynamically adjusted for the structure types including both uplink and downlink (for example, according to neighbor interference, TA demand, etc.) Dynamically determine the GP size to dynamically adjust the size of the upstream and/or downstream regions).

For another example, the indication information indicates that the time unit is one of a plurality of pre-defined or configured structure types including uplink and downlink; wherein the predefined or configured multiple types include both uplink and downlink structure types. Each structure type in the network corresponds to different uplink and downlink allocation ratios (ie, contains different numbers of uplink and downlink symbols).

For another example, the indication information indicates that the time unit is one of a full-up or full-down or uplink-based or downlink-based structure type; wherein, multiple uplink-based and/or lower-layer behaviors may be predefined or configured. The main structure type, which corresponds to different uplink and downlink allocation ratios (that is, contains different numbers of uplink and downlink symbols).

When the terminal determines, according to the indication information, that the time unit in which the uplink shared channel is transmitted is a full downlink, the terminal discards the current transmission. For example, for a semi-persistent scheduling (SPS) uplink shared channel, according to the pre-configured transmission period, when the time unit of the SPS uplink shared channel determined according to the period is full downlink, the SPS uplink is not transmitted at this time. For example, for the uplink shared channel retransmission triggered by the PHICH, when the time unit in which the PHICH triggered uplink shared channel transmission is determined to be the full downlink according to the timing definition of the PHICH and the corresponding uplink shared channel retransmission, the transmission is not transmitted. The upstream shared channel triggered by the PHICH.

When the terminal does not detect the indication information for determining the uplink area of the time unit in which the uplink shared channel transmission is located, or fails to detect the indication information (for example, the CRC check fails), the terminal does not perform in the time unit. Uplink transmission, or the terminal transmits an uplink shared channel according to the size and/or location of the pre-agreed or configured time domain resource in the time unit (this is equivalent to presetting that the time unit always includes the uplink area, if If the time unit is full down, it is not applicable). The size of the pre-agreed or configured time domain resource can be expressed as A symbol, or B mini-slot; the pre-agreed or configured time domain location may be represented as the last A symbol or B mini-slots in a time unit; for example, the pre-agreed or configured time domain resource is The last 2 symbols in a time unit, or the last 1 mini-slot.

When the terminal determines, according to the indication information, that the time unit in which the uplink shared channel is transmitted is a full downlink, the terminal discards the current transmission.

When the terminal determines, according to the indication information, that the time unit in which the uplink shared channel transmission is located includes the downlink area and the uplink area, and the time unit after the time unit in which the uplink shared channel is transmitted is a full uplink, the terminal according to the pre-arrangement or configuration, Independently transmitting the uplink shared channel in the time unit after the time unit of the uplink shared channel transmission and the time unit in which the uplink shared channel is transmitted (ie, one uplink shared channel does not transmit over two time units, only at one time) Transmitting in the unit, or transmitting an uplink shared channel in a time unit after the time unit in which the uplink shared channel is transmitted and the time unit in which the uplink shared channel is transmitted (ie, one uplink shared channel is transmitted across two time units) .

That is, the time unit in which the uplink shared channel is transmitted may be one time unit or a plurality of consecutive time units; if there are multiple, the uplink area is all uplink areas in the multiple time units; before that, The terminal receives the indication information, and determines, according to the indication information, an uplink area in a time unit in which the uplink shared channel is transmitted.

For example, the terminal determines, according to the indication information, that the i-th time unit includes a downlink area and an uplink area, and the i+1th time unit is a full uplink, the terminal may be in the i-th time unit and the i-th according to a pre-arrangement or configuration. Two uplink shared channels are transmitted in the +1 time unit (ie, one uplink shared channel does not transmit over two time units, and is transmitted in only one time unit), The uplink resources in the i-th time unit and the i+1th time unit may also be combined to transmit one uplink shared channel (ie, one uplink shared channel is transmitted across two time units).

There are two implementation methods for the terminal to send the uplink shared channel in the uplink area. The following two methods are respectively introduced.

(1) Method 1

The terminal transmits the uplink shared channel according to the time domain size of the uplink area in the time unit in which the uplink shared channel is not transmitted with the corresponding scheduling signaling or the time domain size of the preset area used for transmitting data in the uplink area. The preset area for transmitting data in the uplink area may be a pre-agreed or configured area for transmitting data in the uplink area.

In a specific implementation manner, the terminal performs coding/rate matching on the data information transmitted by the uplink shared channel according to the time domain size of the uplink area, and maps the encoded/rate matched data information to the uplink. The area performs transmission coding; or the terminal encodes/rates the data information transmitted by the uplink shared channel according to the time domain size of the preset area, and maps the coded/rate matched data information to the preset. Send on the area.

That is, the terminal uses all the symbols in the uplink area or all the symbols in the area for transmitting data in the uplink area or in the uplink area for the uplink shared channel transmission for coding/rate matching (regardless of the beginning) Pass or retransmit).

In the embodiment of the present invention, the meanings of the symbols include, but are not limited to, Orthogonal Frequency Division Multiplexing (OFDM) symbols, Sparse Code Multiplexing Access (SCMA) symbols, and filtered orthogonal frequency division. Reuse (Filtered Orthogonal Frequency Division Multiplexing (F-OFDM) symbol, Non-Orthogonal Multiple Access (NOMA) symbol, SC-FDMA (Single-carrier Frequency-Division Multiple Access) symbol, CP-OFDM (Cyclic Prefix-Orthogonal Frequency Division Modulation) symbol, PDMA (Pattern Division Multiple Access, or Polarization Division Multiple Access) symbol, which can be determined according to actual conditions, and is not Let me repeat.

Another possible implementation manner is that the terminal encodes/rates the data information transmitted by the uplink shared channel according to the second preset time domain size, and compares the data information of the encoding/rate matching according to the uplink area. The domain size is repeated or truncated, and then mapped to the uplink area for transmission, or the data information after the encoding/rate matching is repeated or truncated according to the time domain size of the preset area, and then mapped to the preset area. send.

Specifically, the same data (such as a transport block) is initially transmitted on one uplink shared channel, and retransmission (retransmission caused by an initial transmission error) or repeated transmission is performed on another uplink shared channel (in order to improve reception performance). When performing multiple repeated transmissions, the terminal only needs to perform the transmission block according to the second preset time domain size (where the second preset time domain size may be the size of the pre-agreed or configured time domain resource) Encoding/rate matching, and each time the uplink shared channel is transmitted, according to the time domain size of the uplink region in the time unit in which the uplink shared channel is transmitted (or pre-agreed or configured for transmitting data in the uplink region) The time domain size of the area, the information after the encoding/rate matching is repeated or truncated to match the time domain size of the uplink area (or the pre-agreed or configured area for transmitting data in the uplink area) Time domain size).

In the embodiment of the present invention, the second preset time domain size may be expressed as A1 Symbol, or B1 mini-slot, where A1, B1 are integers greater than or equal to 1.

For example, the terminal always assumes that the encoding/rate matching is performed according to the time domain resource of 4 symbols, and the uplink area in the time unit in which the transport block is transmitted through the uplink shared channel for the first time and the uplink shared channel is transmitted is When 6 symbols are used, the terminal may repeat the coding/rate matching result, and the mapping is transmitted on 6 symbols; when the transmission block is transmitted through the uplink shared channel for the second time and the time unit of the uplink shared channel is transmitted When the uplink area is 2 symbols, the terminal can truncate the result after encoding/rate matching, and the mapping is transmitted on 2 symbols.

(2) Method 2

The terminal transmits the uplink shared channel in an uplink area in a time unit in which the uplink shared channel transmission is not in the corresponding scheduling signaling according to the first preset time domain size.

The first preset time domain size may be a pre-agreed or configured time domain resource size, and the first preset time domain size may be represented by A2 symbols or B2 mini-slots, where A2 and B2 are An integer greater than or equal to 1. For example, the pre-agreed or configured time domain resource size (the first preset time domain size) may be 2 symbols, or 1 mini-slot.

In a specific implementation, the terminal always performs coding/rate matching on the data carried on the uplink shared channel according to the size of the pre-agreed or configured time domain resource.

When the size of the pre-agreed or configured time domain resource does not exceed the time domain size of the uplink area or does not exceed the time domain size of the area for transmitting data pre-agreed or configured in the uplink area, the terminal encodes the time domain. The result of the rate matching is mapped to the preset time domain location in the uplink area or the pre-agreed or configured area for transmitting data in the uplink area, where the preset time domain location is in the uplink area or the uplink area. Pre-agreed or configured for transmission The size of the pre-agreed or configured time domain resource in the region of the material.

For example, the preset time domain location may be that the first symbol in the uplink area or the area in the uplink area that is pre-appointed or configured for transmitting data begins to satisfy the size of the pre-agreed or configured time domain resource. An area, or an area of the area in the uplink area or the uplink area that is pre-agreed or configured for transmitting data, which satisfies the size of the pre-agreed or configured time domain resource, and may of course not be in the time domain. continuous.

For another example, the preset time domain location may be the size of a plurality of the pre-agreed or configured time domain resources included in the uplink area or the area for pre-arranging or configuring the data in the uplink area. One of the domain resources (that is, the area in the uplink area or the uplink area that is pre-agreed or configured for transmitting data includes a plurality of preset time domain locations, and the terminal can independently select which time domain location to transmit. ).

When the size of the pre-agreed or configured time domain resource exceeds the time domain size of the uplink area or exceeds the time domain size of the area for transmitting data pre-agreed or configured in the uplink area, the terminal encodes the code/rate The result of the matching is truncated according to the time domain size of the uplink area, and is mapped to all symbols in the uplink area or the pre-agreed or configured area for transmitting data in the uplink area, or the terminal directly gives up the present Secondary transmission.

In this case, regardless of the time unit in which the uplink shared channel is transmitted, the uplink shared channel transmission is transmitted according to a fixed number of symbols, even if the uplink areas included in different time units may be different, for the bearer in the uplink shared channel. Multiple transmissions of the same original information (such as retransmissions, or repeated transmissions), no need to re-encode/rate match for each transmission.

FIG. 3 exemplarily shows an information transmission provided by another embodiment of the present invention. Schematic diagram of the process corresponding to the input method. As shown in FIG. 3, the method includes the following steps: Step 301: The network device sends indication information to the terminal, where the indication information is used by the terminal to determine an uplink area where the uplink shared channel is transmitted; The network device receives the uplink shared channel sent by the terminal in the uplink area.

In the embodiment of the present invention, the network device sends the indication information to the terminal, so that the terminal determines the transmission resource of the uplink shared channel according to the indication information, and transmits the uplink shared channel on the transmission resource of the uplink shared channel, thereby facilitating the network device to be correct. Receive the upstream shared channel.

It should be noted that the method in the embodiment shown in FIG. 3 corresponds to the method in the embodiment shown in FIG. 2, and the difference is that the implementation process of the terminal is specifically described in the embodiment shown in FIG. 2, and FIG. 3 The implementation process of the network device is specifically described in the illustrated embodiment. Therefore, in the embodiment shown in FIG. 3, the implementation process of the network device will be described. For other related content, refer to FIG. 2 above. The description in the embodiment will not be repeated here.

Specifically, in step 301, the network device may send the indication information to the terminal in a time unit before the time unit in which the uplink shared channel is transmitted or the time unit in which the uplink shared channel is transmitted.

The indication information may indicate a time domain size and/or a time domain location of an uplink region in a time unit in which the uplink shared channel is transmitted.

The indication information may also indicate uplink and downlink resource division of the time unit in which the uplink shared channel is transmitted. The uplink and downlink resources are specifically divided into: at least two of a downlink resource, an uplink resource, and a guard interval GP resource, where the downlink resource includes a downlink zone. The size and/or location of the domain, the uplink resource includes the size and/or location of the uplink region, the GP resource includes the size and/or location of the GP, or the indication information indicates the upper and lower time units of the uplink shared channel transmission The row structure type, the uplink and downlink structure type is at least one of full uplink, full downlink, and both uplink and downlink structure types. The type of structure including both uplink and downlink further includes an uplink-based or downlink-based structure type.

The indication information is carried in the high layer signaling, or is carried in the broadcast channel, or is carried in the downlink control channel; and/or the indication information is exclusive to the terminal or shared by the terminal with other terminals.

When the network device does not send the indication information or the indication information fails to be sent, the network device does not receive the uplink transmission in the time unit, or the network device follows the pre-approved or configured time domain resource in the time unit. The size and/or location receives the upstream shared channel.

When the time unit in which the uplink shared channel is transmitted is full downlink, the network device does not receive the uplink transmission.

When the time unit in which the uplink shared channel is transmitted includes the downlink area and the uplink area, and the time unit after the time unit in which the uplink shared channel is transmitted is a full uplink, the network device is respectively shared in the uplink according to a pre-arrangement or configuration. The time unit in which the channel is transmitted and the time unit after the time unit in which the uplink shared channel is transmitted receive the uplink shared channel that is independently transmitted, or the time unit in which the uplink shared channel is transmitted and the time in which the uplink shared channel is transmitted An uplink shared channel is received in the time unit after the unit.

There are two implementation methods for the network device to receive the uplink shared channel in the uplink area. The following two methods are respectively introduced.

(1) Method 1: Corresponding to the method executed by the terminal in the embodiment shown in FIG. 2

Receiving, by the network device, the time domain size of the uplink area in the time unit in which the uplink shared channel transmission in which the corresponding scheduling signaling is not present, or the time domain size of the pre-agreed or configured area for transmitting data in the uplink area, The upstream shared channel.

In a specific implementation manner, the network device performs channel decoding/de-rate matching on the data information transmitted by the uplink shared channel according to the time domain size of the uplink area or the time domain size of the preset area.

For example, the network device performs channel decoding/de-rate matching for the uplink shared channel transmission according to all symbols in the uplink area or all symbols in the area for transmitting data pre-agreed or configured in the uplink area. Whether it is initial or retransmission).

Another possible implementation manner is that the network device is configured according to the second preset time domain size and the time domain size of the uplink area, or according to the second preset time domain size and the time domain size of the preset area. After determining whether the terminal repeats or truncates the data information after the encoding/rate matching, the partial information in the data information transmitted by the uplink shared channel is merged or the truncated partial information is complemented, and according to the The second preset time domain size performs channel decoding/de-rate matching on the merged data information or the data information after the complement.

For example, for the same data (such as a transport block) to perform initial transmission on one uplink shared channel, retransmission (retransmission caused by initial transmission error) or repeated transmission on another uplink shared channel (in order to improve reception performance) The network device only needs to decode/de-rate the transmission block according to the pre-agreed or configured time domain resource size. When receiving each uplink shared channel transmission, according to the uplink shared channel transmission The time domain size of the upstream region in the time unit (or pre-agreed or configured in the upstream region for transmission) The time domain size of the area in which the data is transmitted and the size of the pre-agreed or configured time domain resource are determined, and the terminal determines whether the information after the encoding/rate matching is repeated or truncated to match the time domain size of the uplink area (or the uplink) The pre-agreed or configured time domain size of the area in the area for transmitting data. The network device may transmit the uplink shared channel according to the terminal repeating or truncating reversible process before performing decoding/de-rate matching. The repeated information of the information received on the time domain size of the uplink area in the time unit (or the time domain size of the pre-agreed or configured area for transmitting data in the uplink area) is merged and truncated The part is complemented and the channel decoding/de-rate matching is performed on the combined data information or the information information after the complement.

(2) Method 2: Corresponding to the method 2 executed by the terminal in the embodiment shown in FIG. 2

The network device always receives the uplink shared channel in an uplink area in a time unit in which the uplink shared channel transmission without the corresponding scheduling signaling is located according to the size of the pre-agreed or configured time domain resource.

In a specific implementation, the network device always performs decoding/de-rate matching on the data carried on the uplink shared channel according to the size of the pre-agreed or configured time domain resource.

When the size of the pre-agreed or configured time domain resource does not exceed the time domain size of the uplink area or does not exceed the time domain size of the area for transmitting data pre-agreed or configured in the uplink area, the network device is Obtaining information on the preset time domain location in the area for transmitting data pre-arranged or configured in the uplink area or the uplink area, and performing decoding/de-rate matching on the information, where the preset time domain location is The size of the pre-agreed or configured time domain resource in the uplink area or the area in the uplink area that is pre-agreed or configured for transmitting data.

For example, the preset time domain location may be the uplink area or the uplink area. The area in the area for transmitting data that is pre-agreed or configured in advance, the area that satisfies the size of the pre-agreed or configured time domain resource, or the pre-agreed or configured in the uplink area or the uplink area The latter part of the area in which the data is transmitted satisfies the area of the size of the pre-agreed or configured time domain resource, and of course may also be discontinuous in the time domain.

For another example, the preset time domain location may be the size of a plurality of the pre-agreed or configured time domain resources included in the uplink area or the area for pre-arranging or configuring the data in the uplink area. One of the domain resources (that is, the area in the uplink area or the uplink area that is pre-agreed or configured for transmitting data includes a plurality of preset time domain locations, and the terminal can independently select which time domain location to transmit. The network device needs to blindly check whether there is uplink shared channel transmission in each time domain location.

When the size of the pre-agreed or configured time domain resource exceeds the time domain size of the uplink area or exceeds the time domain size of the area for transmitting data pre-agreed or configured in the uplink area, the network device determines the terminal The result of the encoding/rate matching is truncated according to the time domain size of the uplink area, and the network device acquires all the symbols in the area for transmitting data pre-agreed or configured in the uplink area or the uplink area. Encoding information, and complementing the encoded information to obtain encoded information having a length equal to the complemented bit of the encoded information that has not been truncated, and decoding/solving the encoded information after the complementary bit The rate matches, or the network device determines that the terminal has abandoned the transmission without any reception.

It should be noted that the time domain size in the embodiment of the present invention refers to the number of symbols or mini-slots or slots or subframes included, for example, the time domain size is A symbols, or B mini-slots. Or C slots or D sub-frames, wherein the mini-slot is defined as a time unit containing X symbols, and X, A, B, C, and D are integers greater than or equal to 1; the time domain position refers to The index or number of the included symbol or mini-slot or slot or sub-frame.

The information transmission method in the embodiment of the present invention is introduced below in conjunction with a specific embodiment.

Taking a slot as a time unit as an example, suppose a slot contains 7 symbols (OFDM or SC-FDMA symbols); of course, other lengths of time unit definition are not excluded; assuming a specific time-frequency position in the current time unit The sent indication information is used to indicate the uplink and downlink area division in the current time unit (of course, only the uplink area may be indicated), as shown in FIG. 4a; it is assumed that the indication information sent by the specific time-frequency position in the current time unit is used to indicate the next one. The division of the uplink and downlink areas in the time unit (of course, it is also possible to indicate only the uplink area), as shown in FIG. 4b.

The following is based on the perspective of network devices.

The network device determines the downlink area and the uplink area size divided by the time unit i, and sends indication information on the specific time-frequency resource in the time unit i that sends the indication information, for notifying the uplink and downlink area division of the time unit i. The two indication information in the downlink area size, the uplink area size, and the GP size in the time unit i may be notified, or one of a plurality of predefined uplink and downlink structure types may be notified.

For the unscheduled grant-free terminal, the PUSCH is sent to the blind-checking terminal on the time domain and/or the frequency domain resource configured for the terminal; wherein the grant-free terminal can only configure the frequency domain resource, then the time domain The resource considers that all the uplink areas can be transmitted by the physical uplink shared channel (PUSCH), or the time domain resources can be configured at the same time. The time domain resources can include the configuration that only the partial-time unit can perform grant-free transmission. It is also possible to send a grant-free in each time unit, and the time domain resource can also The method includes sending a PUSCH according to a pre-agreed or configured fixed-size time domain resource in a time unit that can perform grant-free transmission, that is, method 2, in this case, for example, as shown in FIG. 4a or FIG. 4b, assuming that the time unit is i+1. The UL area contains 4 symbols, that is, when a mini-slot is defined to contain 2 symbols, at this time, one UL area contains 2 mini-slots, and if a PUSCH transmission is agreed to occupy 2 symbols, that is, a mini-slot transmission, Then, in the UL area, there are two time domain locations that can transmit the PUSCH, and the grant-free terminal can select one of the PUSCHs when the uplink transmission is needed, such as PUSCH2 in FIG. 4a or PUSCH4 in FIG. 4b, and the network device needs The PUSCH is blindly detected in the first two symbols in the UL region, that is, the first mini-slot and the second two symbols, that is, the second mini-slot; of course, if the grant-free terminal is not configured or the PUSCH transmission is fixed. The time domain resource size is Method 1, that is, all symbol transmissions in the UL area are occupied, such as PUSCH1 and PUSCH3 in FIG. 4a, PUSCH1, PUSCH2, and PUSCH3 in FIG. 4b, and the network device follows the corresponding UL area. All symbols are blindly checked for PUSCH.

For the PUSCH of the SPS, according to the SPS period, in the time unit determined by the SPS period, on the frequency domain resource indicated by the downlink control channel instructed by the SPS resource in the time unit (of course, the time domain resource may also be indicated, It is equivalent to the pre-configured fixed-size time domain resource transmission in the time unit determined by the SPS period, that is, the method 2; of course, if the time domain resource size of each transmission is not indicated or agreed, the method 1) receives the SPSPUSCH .

For the PHSCH-triggered PUSCH retransmission, the PUSCH sent by the terminal is received in the UL region in the corresponding time unit according to the timing relationship between the PHICH and the retransmission PUSCH (may be the method 1 on all symbols in the uplink region in the time unit) Received, or pre-configured or agreed upon at a fixed symbol location).

For the foregoing PUSCH, if it is determined according to the time unit that the uplink regions in the two adjacent time units are consecutive, for example, the time unit i+1 includes the downlink region and the uplink region, and the time unit i+2 is the full uplink, the pre-agreed or The configuration determines that the PUSCH is respectively transmitted in the uplink area in each time unit, that is, one PUSCH does not transmit across two time units, for example, PUSCH1 and PUSCH3 in FIG. 4b, and the uplink areas in the two time units may also be combined and transmitted. A PUSCH, that is, one PUSCH, may be transmitted across two time units, for example, PUSCH2 in FIG. 4b; the terminal and the network device agree on a certain transmission mechanism for this situation to ensure that both sides understand each other.

The following is based on the perspective of the terminal.

Detecting the indication information on the specific time-frequency resource in each time unit that sends the indication information, and determining the uplink and downlink area division of the corresponding time unit, and the specific notification manner is consistent with the network device agreement, and may be the network device side. List any of the ways.

For the grant-free terminal, when the terminal has uplink data to be sent, the PUSCH can be sent on the time-frequency domain resource configured for the terminal. The grant-free terminal can only configure the frequency domain resource. The domain resource considers that all uplink areas can be PUSCH-transmitted, and can also configure time-domain resources. The time-domain resources can include configurations that can be sent only in some time units, or in each time unit. The granting of the grant-free, the time domain resource may also include sending the PUSCH according to a pre-agreed or configured fixed-size time domain resource in a time unit that can perform grant-free transmission, that is, method 2, in this case, for example, FIG. 4a or FIG. As shown in 4b, it is assumed that the UL area in the time unit i+1 contains 4 symbols, that is, when a mini-slot is defined to contain 2 symbols, one UL area contains 2 mini-slots at this time, if a PUSCH transmission is fixed. Take up 2 symbols, ie a mini-slot If the transmission is performed, there are two time domain locations in the UL zone to transmit the PUSCH. The grant-free terminal may select one of the PUSCHs when the uplink transmission is required, such as PUSCH2 in FIG. 4a or PUSCH4 in FIG. 4b; The grant-free terminal does not configure or stipulate the fixed time domain resource size of the PUSCH transmission, and is Method 1, that is, all symbol transmissions in the UL area are occupied, such as PUSCH1 and PUSCH3 in FIG. 4a, and PUSCH1 and PUSCH2 in FIG. 4b.
