Description

Transmission method of uplink information, first communication equipment and second communication equipment

Technical Field

Embodiments of the present application relate to a communication system, and in particular, to a transmission method of uplink information, a first communication device, and a second communication device.

Background

Fifth generation mobile communication system (The 5) ^th Generation, 5G) supports a flexible slot structure, where a slot contains 14 symbols, each of which can be used for uplink or downlink transmission in a slot. The base station may send Slot Format Information (SFI) to the terminal to inform the terminal of the Slot structure, for example, which symbols of the Slot are used for uplink transmission, which symbols are used for Downlink transmission, and which symbols are in an unknown (unknown) Format, and for the symbols in the unknown Format, the terminal does not send or receive Information, and the SFI may be included in a Group Common Physical Downlink Control Channel (Group Common PDCCH) sent by the base station to a Group of terminals to inform a Group of terminal of the Slot Format scheduled by the base station.

When the terminal is to transmit uplink information to the base station, the base station may schedule uplink resources for the terminal, so that the terminal transmits uplink information, such as uplink data or uplink control information, to the base station on the uplink resources allocated by the base station. When the resource format indicated by the SFI sent to the terminal by the base station is used for downlink transmission or is unknown, the SFI cannot be used for uplink transmission, and at this time, if the format indicated by the SFI is downlink transmission or the unknown resource is exactly the resource that the base station schedules for uplink information transmission to the terminal, that is, when the uplink resource allocated by the base station conflicts with the downlink resource or the unknown resource indicated by the SFI, the terminal cannot judge on which resources the uplink information is sent to the base station.

The following describes embodiments of the present application in more detail by taking the second communication device and the first communication device as examples with reference to specific examples.

Fig. 2 is a diagram of a method, a first communication device, a second communication device, and a system for transmitting uplink information according to an embodiment of the present application. As shown in fig. 6, the first communication device includes a receiving unit 61, a determining unit 62, and a transmitting unit 63, wherein the receiving unit 61 and the transmitting unit 63 may be replaced by a transceiving unit. As shown in fig. 7, the second communication device includes a transmitting unit 71, a determining unit 72, and a receiving unit 73, wherein the transmitting unit 71 and the receiving unit 73 may be replaced by a transceiving unit.

When the second communication device is a network device or a base station, when the first communication device is a terminal device or a user equipment, the determining unit 62 or the determining unit 72 may be a processor, the receiving unit 61, the receiving unit 73, the transmitting unit 63, the transmitting unit 71, or the transmitting and receiving unit may be a transceiver, and the transceiver may be a radio frequency circuit, and when the first communication device includes a storage unit, the storage unit is configured to store computer instructions, and the processor is communicatively connected to the memory, and the processor executes the computer instructions stored in the memory, so that the first communication device or the second communication device executes the method according to the embodiment of fig. 2. The processor may be a general purpose Central Processing Unit (CPU), a microprocessor, or an application-specific integrated circuit (ASIC).

When the first communication device or the second communication device is a chip, the determining unit 62 or the determining unit 72 may be a processor, the receiving unit 61 or the receiving unit 73 may be an input interface, a pin, a circuit, or the like, the transmitting unit 63 or the transmitting unit 71 may be an output interface, a pin, a circuit, or the like, and the transceiving unit may be an input/output interface, a pin, a circuit, or the like, for example. The processing unit may execute computer-executable instructions stored by the storage unit to cause a chip within the first communication device or the second communication device to perform the method of fig. 2. Optionally, the storage unit is a storage unit in the chip, such as a register, a cache, and the like, and the storage unit may also be a storage unit located outside the chip in the terminal, such as a read-only memory (ROM) or another type of static storage device that can store static information and instructions, a Random Access Memory (RAM), and the like.

The specific steps of the uplink information transmission method according to the embodiment of fig. 2 are as follows:

in step 21, the transmitting unit 71 of the second communication device transmits the first control information to the first communication device in the time slot m, and the receiving unit 61 of the first communication device receives the first control information from the second communication device in the time slot m. Optionally, the timeslot includes x symbols (symbol), and the timeslot may also be replaced by time granularity of other time lengths, for example, the timeslot may be replaced by a subframe or a minislot (mini slot), one timeslot includes 14 or 12 symbols, and the following description takes 1 timeslot including 14 symbols as an example. The first control information is used to indicate a first time resource used for uplink information transmission in a timeslot m + k, where the first time resource includes at least one symbol, m and k are non-negative integers, x is a positive integer, and the first control information is preferably an uplink scheduling Grant (UL Grant), and the following description takes the first control information as the UL Grant as an example.

For example, as shown in fig. 3 or 4, the second communication device sends UL Grant to the first communication device in time slot m, so as to schedule the first communication device to send uplink information to the second communication device in time slot m + k from symbol 0 to symbol 13 (shown in fig. 3), or to schedule the first communication device to send uplink information to the second communication device in time slot m + k from symbol 0 to symbol 6 (shown in fig. 4).

Step 22, the sending unit 71 of the second communication device sends the second control information to the first communication device at a time slot n, the receiving unit 61 of the first communication device receives the second control information from the second communication device at the time slot n, where n is a non-negative integer, and the time slot n is before the time slot m + k, that is, the time slot n where the second communication device sends the second control information should be before the time slot m + k where the second communication device receives the uplink information from the first communication device. The second control information is used to indicate types of x symbols included in the slot m + k, where the types include uplink, downlink, or unknown, and the second control information may be SFI, and the second control information is SFI as an example for description below. The SFI may indicate which symbols on the slot m + k are used for uplink transmission and which symbols are used for downlink transmission, that is, the SFI may indicate whether a certain symbol included on the slot m + k is used for uplink transmission or downlink transmission, and of course, the SFI may also indicate which symbols on the slot m + k are unknown in type, that is, the first communication device may not transmit information to the base station or receive information from the base station on the symbols whose type is unknown. The unknown type may also be replaced by other types, such as sidelink, again as indicated by signaling as downlink or uplink. Preferably, the SFI may indicate a specific type of any one symbol included in a certain slot. And at least one symbol with the type of uplink on the time slot m + k forms a second time resource.

In step 23, the determining unit 72 of the second communication device determines a third time resource according to the first time resource and the second time resource.

In step 24, the determining unit 62 of the first communication device determines a third time resource according to the first time resource and the second time resource.

The sequence of step 23 and step 24 is not limited, and in step 23 and step 24, the third time resource is at least one symbol used for uplink information transmission in the timeslot m + k. The uplink Information includes uplink data or uplink control Information, and the uplink control Information includes Scheduling Request (SR), feedback Information (ACK or NACK), or Channel State Information (CSI).

As shown in fig. 3, when the first time resource and the second time resource contain the same symbol, the third time resource is the same symbol contained in the first time resource and the second time resource, and the same symbol refers to at least one symbol belonging to both the first time resource and the second time resource. For example, in fig. 3, the UL Grant sent by the second communication device to the first communication device indicates that resources used for uplink information transmission in the slot m + k are symbol 0 to symbol 13, that is, the first time resource is symbol 0 to symbol 13, and the SFI sent by the second communication device to the first communication device indicates that types of symbol 0 to symbol 5 in the slot m + k are downlink, symbol 6 is unknown, symbol 7 to symbol 13 are uplink, that is, symbol 7 to symbol 13 constitute the second time resource, and the third time resource is the same symbol 7 to symbol 13 included in the first time resource and the second time resource. The transmitting unit 63 of the first communication device transmits uplink information to the second communication device on the same symbols (i.e., symbol 7 to symbol 13) included in the first time resource and the second time resource.

As shown in fig. 4, when the first time resource and the second time resource do not include the same symbol, the number of symbols included in the second time resource is smaller than the number of symbols included in the first time resource, and the third time resource is the second time resource. For example, in fig. 4, the UL Grant sent by the second communication device to the first communication device indicates that resources used for uplink information transmission in slot m + k are symbol 0 to symbol 6, that is, the first time resource is symbol 0 to symbol 6, and the SFI sent by the second communication device to the first communication device indicates that types of symbol 0 to symbol 8 in slot m + k are downlink, symbol 9 is unknown, symbol 10 to symbol 13 are uplink, that is, symbol 10 to symbol 13 constitute the second time resource, the second time resource includes 4 symbols, the first time resource includes 7 symbols, and the third time resource includes symbol 10 to symbol 13 included in the second time resource. The transmitting unit 63 of the first communication device transmits uplink information to the second communication device on the second time resource (i.e., symbol 10 to symbol 13).

As shown in fig. 5, when a first time resource and a second time resource do not include the same symbols, the number of symbols included in the second time resource is greater than or equal to the number of symbols included in the first time resource, the third time resource is predefined M symbols of the second time resource, M is a positive integer, M is the number of symbols included in the first time resource, and the predefined M symbols are the first M symbols of the second time resource, the last M symbols of the second time resource, or any M symbols of the second time resource. For example, in fig. 5, the UL Grant sent by the second communication device to the first communication device indicates that resources used for uplink information transmission in slot m + k are symbol 0 to symbol 2, that is, the first time resource is symbol 0 to symbol 2, and the SFI sent by the second communication device to the first communication device indicates that types of symbol 0 to symbol 8 are downlink, symbol 9 is unknown, symbol 10 to symbol 13 are uplink, that is, symbol 10 to symbol 13 constitute the second time resource, the second time resource includes 4 symbols, the first time resource includes 3 symbols, and the third time resource is symbol 10 to symbol 12, or symbol 11 to symbol 13 included in the second time resource. The transmitting unit 63 of the first communication device transmits uplink information to the second communication device on the predefined M symbols of the second time resource, and the receiving unit 73 of the second communication device receives the uplink information from the first communication device on the predefined M symbols of the second time resource.

When the uplink information is uplink control information, the uplink control information includes SR information, ACK/NACK information, or CSI information, different uplink control information has different priorities, and the preferred priority order is SR > ACK/NACK > CSI, and if the third time resource is limited and is not sufficient for the first communication device to transmit all the uplink control information, the first communication device may give up transmitting the uplink control information with low priority according to the priority of the uplink control information in the order from low priority to high priority, and only transmit a part of the uplink control information with high priority. The first communication device may also send the upstream control information associated with the channel (piggyback) to the second communication device after sending the upstream data. Therefore, the first communication equipment can ensure that the uplink control information with high priority can be completely and accurately sent to the second communication equipment.

If the resource for uplink information transmission indicated by the UL Grant sent by the second communication device to the first communication device only contains one Transport Block (TB), and the Transport Block contains critical information of the Transport Block, such as a system bit, the first communication device abandons the uplink resource scheduled by the UL Grant to transmit uplink information, and waits for the second communication device to schedule the uplink resource for the first communication device again for transmission of uplink information.

In step 25, the sending unit 63 of the first communication device sends the uplink information to the second communication device at the third time resource, and the receiving unit 73 of the second communication device receives the uplink information from the first communication device at the third time resource.

Optionally, before the first communication device sends the uplink information to the second communication device at the third time resource, the determining unit 62 of the first communication device may determine whether the third time resource satisfies the first condition, when the third time resource satisfies the first condition, the sending unit 63 of the first communication device sends the uplink information to the second communication device at the third time resource, before the second communication device receives the uplink information from the first communication device at the third time resource, the determining unit 72 of the second communication device may determine whether the third time resource satisfies the first condition, and when the third time resource satisfies the first condition, the receiving unit 73 of the second communication device receives the uplink information from the first communication device at the third time resource. The first condition may be that the number of symbols included in the third time resource is greater than or equal to a first threshold. The first threshold may be x symbols, x is a natural number, and the first threshold may be predefined by a protocol or may be sent to the first communication device by the second communication device. Therefore, the first communication device can be ensured to transmit the uplink information to the base station only when the first communication device has enough uplink resources through the setting of the first threshold value, so as to ensure the integrity and the accuracy of the transmitted uplink information.

The first condition may also be that a ratio of the number of symbols included in the third time resource to the number of symbols included in the first time resource is greater than or equal to a second threshold. Wherein the second threshold is a true score, and the second threshold may be predefined by a protocol or sent to the first communication device by the second communication device. Therefore, the first communication device can be ensured to send the uplink information to the base station only when the first communication device has the uplink resource occupying the sufficient proportion of the first time resource through the setting of the second threshold value, so as to ensure the integrity and the accuracy of the sent uplink information.

When the time N is greater than or equal to the shortest processing time required for the transmitting unit 63 of the first communication apparatus to prepare to transmit the uplink information, it is preferable that the transmitting unit 63 of the first communication apparatus transmits the uplink information to the second communication apparatus in a rate-matched manner, and the receiving unit 73 of the second communication apparatus decodes the uplink information received from the first communication apparatus in a rate-matched manner. The rate matching means an information transmission method of determining a coding method and/or a modulation method of information to be transmitted according to the size of the transmission resource, that is, the first communication device may code and/or modulate the uplink information according to the size of the third resource, and then transmit the coded and/or modulated uplink information to the second communication device. Taking fig. 3 as an example, the resource for transmitting uplink information scheduled by the second communication device is originally 14 symbols of the first time resource, but because the uplink resource indicated by the SFI has only 7 symbols (symbol 7 to symbol 13), the first communication device may encode and/or modulate the uplink information to be transmitted according to the actually available 7 symbols of the uplink resource, and then transmit the encoded and/or modulated uplink information to the second communication device. Of course, when the time N is greater than or equal to the shortest processing time required for the transmitting unit 63 of the first communication device to prepare to transmit the uplink information, the first communication device may transmit the uplink information to the second communication device in a puncturing manner. The shortest processing time is the shortest time for the first communication device to perform coding and rate matching on the uplink information in order to transmit the uplink information, the time N is the time interval between the time slot N and the time slot m + k, and the time interval may also be the number of time slots or the number of symbols spaced between the time slot N and the time slot m + k. The receiving unit 73 of the second communication apparatus may receive, from the first communication apparatus, capability information of the first communication apparatus, the capability information indicating a shortest processing time required for the first communication apparatus to prepare to transmit uplink information. Therefore, the method for sending the uplink information can be selected more reasonably according to the time interval between the time slot n and the time slot m + k and the processing time of the first communication equipment, so that the integrity and the accuracy of sending the uplink information are enhanced.

When the time N is less than the shortest processing time, the transmitting unit 63 of the first communication apparatus transmits uplink information to the second communication apparatus in a puncturing manner, and the receiving unit 73 of the second communication apparatus decodes uplink information received from the first communication apparatus in a puncturing manner. The puncturing refers to a method of discarding a part of information to be transmitted and transmitting only the remaining part of the information, that is, the first communications device discards a part of the uplink information according to the size of the third resource, that is, puncturing, and then transmits the remaining uplink information after puncturing to the second communications device. Taking fig. 4 as an example, the resource scheduled by the second communications device for transmitting uplink information is originally 7 symbols (symbol 0 to symbol 6) of the first time resource, but since the uplink resource indicated by the SFI has only 4 symbols (symbol 10 to symbol 13), the resource actually available for uplink information transmission only occupies 4/7 of the resource scheduled by the second communications device, and therefore, the first communications device will drop or discard the 3/7 of the uplink information, and then send only the remaining 4/7 to the second communications device. Therefore, the method for sending the uplink information can be selected more reasonably according to the time interval between the time slot n and the time slot m + k and the processing time of the first communication equipment, so that the integrity and the accuracy of sending the uplink information are enhanced.

When the ratio of the number of symbols included in the third time resource to the number of symbols included in the first time resource is less than or equal to a third threshold, the sending unit 63 of the first communication device sends the uplink information to the second communication device in a rate matching manner, and the receiving unit 73 of the second communication device decodes the uplink information received from the first communication device in a rate matching manner. When the ratio of the number of symbols included in the third time resource to the number of symbols included in the first time resource is greater than a third threshold, the transmitting unit 63 of the first communication device transmits uplink information to the second communication device in a puncturing manner, and the receiving unit 73 of the second communication device decodes uplink information received from the first communication device in a puncturing manner. Wherein the third threshold is a true score, and the third threshold may be predefined by a protocol or sent to the first communication device by the second communication device.

The receiving unit 61 included in the first communication device may be replaced by a receiver, the determining unit 62 may be replaced by a processor, and the transmitting unit 63 may be replaced by a transmitter. The transmitting unit 71 included in the second communication device may be replaced by a transmitter, the determining unit 72 may be replaced by a processor, and the receiving unit 73 may be replaced by a receiver.
