Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a method for scheduling an uplink shared channel, and a mobile terminal and a network device using the same.
Background
After the 5G first edition standard is completed, 5G will be extended to different domains. One important direction is the use of unlicensed bands. Compared with the licensed frequency band, the unlicensed frequency band needs to consider coexistence between different systems, typically, a Wifi system, an LTE-based LAA system, and the like. In order to enable various systems to coexist harmoniously, regulatory bodies of various countries adopt a forced Listen Before Talk (LBT) technology for the use of an unlicensed frequency band, that is, data transmission can be performed only when the current channel is sensed to be unoccupied. A problem with this mechanism is that some data cannot be guaranteed to be sent at a certain location.
The uncertainty of the transmission time point due to LBT makes uplink data transmission difficult. Uplink data transmission often needs to be performed according to downlink scheduling. In the current 5G new air interface specification, downlink control information indication (DCI) needs to give a specific time domain and frequency domain position for uplink data channel transmission. When DCI gives a specific time domain location of a Physical Uplink Shared Channel (PUSCH), the location is likely to fail to transmit data due to LBT, resulting in an invalid indication. Even if the terminal is allowed to postpone the point of time of initial transmission, the available time length in the slot may be less than the time length scheduled by the base station due to LBT since the terminal needs to prepare data transmission according to the resource size provided by the base station. In this case, the terminal has to give up the transmission of the current time slot and wait for the next uplink transmission time point, thereby causing uplink resource waste. On the other hand, for the base station, it is also difficult to accurately predict the available time length in the uplink transmission time slot that needs LBT, when only one fixed uplink transmission time length is scheduled, the terminal transmits at the time point that can be transmitted after LBT is finished according to the fixed length, and it is inevitable to leave a blank of several symbols at the end of the transmission time slot. This blank space will also have an impact on the subsequent transmission of slot data. The existence of the blank causes that the LBT process has to be carried out again no matter the terminal or the system is to continue to transmit data. This process makes data transmission discontinuous, further causing waste of system resources.
Disclosure of Invention
The application provides an unlicensed frequency band uplink shared channel scheduling method, a mobile terminal and network equipment, and aims to solve the problem of system resource waste caused by LBT.
The application embodiment provides a method for scheduling an unlicensed frequency band uplink shared channel, which is used for a mobile terminal and comprises an LBT (local binary transmission) occupied symbol, a first data block occupied symbol and a second data block occupied symbol in at least one time slot of a physical uplink shared channel; the LBT occupies the symbol, is used for carrying on the channel monitoring, confirm the symbol number that can be used for data transmission; the first data block occupies symbols and is used for transmitting fixed-length uplink data, and the fixed-length uplink data comprises A continuous symbols; the second data block occupies symbols, is used for transmitting a part of which the number of uplink data symbols is greater than A, and comprises B continuous symbols; A. b is an integer ranging from 0 to 14, and the value of B is the number of symbols between the end of the first data block and the end of the time slot.
Preferably, the value of a is indicated by information in downlink control signaling, or the value of a is configured by higher layer signaling, or the value of a is preset in the mobile terminal and the base station.
The further optimized embodiment of the method of the invention also comprises the following steps:
setting a time window, wherein the duration of the time window is d (represented by symbol number);
if the number of symbols contained in the uplink data which needs to be sent by the mobile terminal is less than or equal to A, sending the uplink data in a first data block;
and if the number of the symbols contained in the uplink data which needs to be sent by the mobile terminal is greater than A, sending the first A symbols in the uplink data in the first data block, preparing for sending the subsequent B symbol data within the time window duration range, and sending the uplink data in the second data block with the length of B after the A symbol data are sent.
Further preferably, when a < d, only the first data block is transmitted.
The application also provides a mobile terminal, which is used for the method of any one embodiment of the application and comprises a terminal data unit and a terminal control unit; the terminal data unit is used for sending the uplink data; the terminal control unit is configured to determine the first data block occupation symbol and the second data block occupation symbol.
The application also provides a network device, which is used for the method of any embodiment of the application and comprises a network data unit and a network control unit; the network data unit is configured to receive the uplink data; the network control unit is used for sending a downlink control signaling, and the downlink control signaling contains information indicating the value A.
The embodiment of the application adopts at least one technical scheme which can achieve the following beneficial effects:
the method and the device for PUSCH single-time-slot two-time continuous data transmission can well match the uncertain length transmission of the uplink time slot after the introduction of the LBT by flexibly allocating the time length of two data blocks. After LBT, when the length of available uplink PUSCH resource is not less than d, the uplink resource can be occupied by adjusting the time length of the second data block. While the uplink resources are well utilized, the extra LBT process brought by unnecessary data transmission interruption can be avoided. In addition, this serial data transmission scheme allows the terminal to prepare for transmission of the second data block when the first data block is transmitted. This also avoids the terminal preparing multiple uplink transmission versions to match the possible different numbers of uplink PUSCH symbols, thereby reducing the pressure on the terminal to prepare for data transmission.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of communication between a network device and a terminal device. Considering a communication system composed of network devices and terminal devices, one network device can transmit and receive data to and from a plurality of terminal devices at the same time. The network device includes a network data unit and a network control unit. The terminal device includes a terminal data unit and a terminal control unit. The network data unit and the terminal data unit transmit data through a downlink data shared channel (PDSCH) and an uplink data shared channel (PUSCH). And the network control unit and the terminal control unit exchange control information through a downlink control channel (PDCCH) and an uplink control channel (PUCCH). The PDCCH transmits Downlink Control Information (DCI) and performs specific transmission format-related contents of the PDSCH, the PUSCH, and the PUCCH. And after the data of the terminal data unit is received, the terminal control unit feeds back whether the data correctly receives the ACK/NACK information or sends the data of the terminal to the network equipment according to the control information sent by the network control unit and the data receiving condition of the terminal data unit. Specifically, information such as ACK/NACK is carried on a PUCCH (uplink control channel).
Fig. 2 is a diagram illustrating positions of available uplink symbols in a timeslot. The application embodiment provides a method for scheduling an unlicensed frequency band uplink shared channel, which is used for a mobile terminal and comprises an LBT (local binary transmission) occupied symbol, a first data block occupied symbol and a second data block occupied symbol in at least one time slot of a physical uplink shared channel; the LBT occupation symbol is used for carrying out channel monitoring and confirming the number of symbols which can be used for data transmission; the first data block occupies symbols, is used for transmitting uplink data with fixed length, comprises A continuous symbols, and starts from the symbol which can be used as uplink data transmission confirmed by the mobile terminal in the LBT process; the second data block occupies symbols, is used for transmitting a part of which the number of uplink data symbols is greater than A, and comprises B continuous symbols; A. b is an integer ranging from 0 to 14, wherein the value of B is the number of symbols between the end of the first data block and the end of the time slot.
For example, in the current DCI scheduling scheme for the PUSCH over the 5G new air interface, information such as a transmission start time point, a duration length, and a frequency domain position of uplink PUSCH primary data transmission is included. In order to transmit on an unauthorized PUSCH, the invention improves on the basis of the prior art, and supports the PUSCH to continuously transmit data twice in one time slot, namely, the part which can be used for transmitting the uplink data in one uplink time slot is divided into three parts, namely, an LBT (local binary transmission) occupied symbol part, a PUSCH first data block occupied symbol part and a PUSCH second data block occupied symbol part.
Downlink Control Information (DCI) of a downlink control channel (PDCCH) that schedules an uplink portion of a current time slot schedules a first data block symbol portion and a second data block portion. Specific scheduling contents include, but are not limited to, a time domain length of a data block. In a special case, a value of A, B being 0 represents that no first data block and no second data block are transmitted, respectively.
Preferably, the value of a is indicated by information in downlink control signaling, or the value of a is configured by higher layer signaling. That is, the length of a is given explicitly. The indication is directly indicated in the DCI information, such as a single bit indication in the DCI or joint indication with other information, or higher layer signaling (such as RRC signaling) is directly configured.
Alternatively, the length of a is implicitly given, meaning that the length of a is agreed between the terminal and the base station. That is, the value of a is preset in the mobile terminal and the base station, for example, the length of a is preset with a corresponding value in the subcarrier interval according to the PUSCH.
The length of B is the number of all symbols after the end of the first data block and before the end of the time slot. It should be noted that the specific value of B is not explicitly indicated in the scheduling information, but is calculated. The calculation is made by subtracting the number of symbols at the end of the first block from the number of symbols contained in a slot, assuming that the symbol number starts at 1 in a slot. For example, a slot contains 14 symbols, the end time of the first data block is the 10 th symbol, and the length of B is 14-10 ═ 4.
FIG. 3 is a flow chart of an embodiment of the method of the present invention. The method specifically comprises the following steps:
in step 300, the "preparation for subsequent B symbol data transmission" includes at least a modulation and coding process and a process of mapping to physical resources.
It should be noted that, when the number of uplink data symbols to be transmitted is greater than a and less than a + B, the second data block is not filled with uplink data, and the idle portion may be filled with default data (e.g., 0), and may also be used to transmit other data, which is not limited in this application.
It should be further noted that, when the number of uplink data symbols to be transmitted is greater than a + B, the second data block is filled with uplink data, and the insufficient portion may occupy other physical resources for transmission (e.g., other time slots).
FIG. 4 is a schematic flow chart of another embodiment of the method of the present invention.
A time window is set, the duration of which is d (in symbol number).
For example, a time window d is set for the terminal to prepare Physical Uplink Shared Channel (PUSCH) data transmission. The length of d may vary from subcarrier spacing to subcarrier spacing, e.g., assuming a length of 1 symbol for a subcarrier spacing of 15kHz, the length of d may increase by 2 symbols for a subcarrier spacing of 30 or 60 kHz.
The value of d may be, for example, an agreed value or a value dynamically determined by the terminal. Specifically, the method comprises the following steps:
value of the contract: for example, the value of d is specified in a technical standard or specification. The value of d can be given, for example, in ms or us as the absolute value of time, or in symbols as the relative length of time.
Dynamically determined values of the terminal: when the terminal accesses the system, the terminal directly reports the capability of the terminal, the reported information comprises a plurality of bits, and each state mark has a value of d.
The embodiment using the time window specifically comprises the following steps:
It should be noted that, in step 600, "preparation for subsequent B symbol data transmission" at least includes a modulation and coding process and a process of mapping to physical resources.
Further preferably, when a < d, only the first data block is transmitted.
As a further optimized embodiment of the present application, if the PUSCH in one slot uses two data block transmissions, the HARQ process numbers corresponding to the first data block and the second data block are different. The two data blocks adopt different HARQ process numbers, and other sending parameters are the same. The purpose of adopting different uplink HARQ process numbers is to perform HARQ control respectively.
As a further optimized embodiment of the present application, the downlink control signaling includes information indicating that the uplink timeslot includes two data blocks, and/or the higher layer signaling includes information indicating that the uplink timeslot includes two data blocks.
For example, there are two indication modes for whether the one-time PUSCH scheduling adopts a transmission structure of two data blocks in one slot: first, the DCI indicates the information directly. The indication of 1 bit is directly added in the DCI, which specially characterizes whether the uplink timeslot that needs LBT is transmitted using two data blocks. And secondly, the indication is directly carried out by high-layer signaling, such as RRC signaling. Adding 1 bit in the high layer signaling directly indicates whether to adopt two data blocks for transmission in the uplink time slot for LBT.
Generally, the first data block and the second data block both use the symbol duration in the uplink timeslot except for the LBT procedure. However, when two-data block scheduling is adopted, if the length of the first data block is equal to the number of available uplink transmission symbols in the current time slot after the LBT process is finished, the second data block is not transmitted. When two data block scheduling is adopted, if the length of the first data block is larger than the number of available uplink transmission symbols of the current time slot after the LBT process, the current time slot does not carry out PUSCH data transmission.
The application also provides a mobile terminal, which is used for the method of any one embodiment of the application and comprises a terminal data unit and a terminal control unit; the terminal data unit is used for sending the uplink data; the terminal control unit is configured to determine the first data block occupation symbol and the second data block occupation symbol.
The application also provides a network device, which is used for the method of any embodiment of the application and comprises a network data unit and a network control unit; the network data unit is configured to receive the uplink data; the network control unit is used for sending a downlink control signaling, and the downlink control signaling contains information indicating the value A.
As an embodiment of further optimizing the network device, the network control unit is further configured to send information indicating that an uplink timeslot includes two data blocks; as a further optimized embodiment of the terminal device of the present application, the terminal control unit is further configured to receive information indicating that an uplink timeslot includes two data blocks.
