Description

Information transmission method and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method and a terminal.

Background

In a mobile communication system, a terminal may achieve different purposes through a random access procedure, for example: the method includes the steps of initial access of a terminal (an initial idle-state idle terminal is connected to a network), Radio Resource Control (RRC) reestablishment, switching, uplink data arrival but uplink desynchronization, terminal switching from an inactive state (inactive) to a connected state (active), uplink synchronization acquisition supporting a Secondary cell (Scell), and the like. The random access procedure is currently divided into a contention random access procedure and a non-contention random access procedure. The non-contention random access process only requires two steps of access of a message I (message1, msg1) and a message II (message2, msg 2). Specifically, as shown in fig. 1, the terminal sends msg1 carrying a Random Access Preamble (Random Access Preamble) to the network device, and the network device feeds back msg2 carrying a Random Access Response (RAR) to the terminal. On the other hand, the contention random access procedure requires four access steps of msg1, msg2, message three (message3, msg3) and message four (message4, msg 4). Specifically, as shown in fig. 2, the terminal sends msg1 carrying a random access preamble to the network device, the network device feeds back msg2 carrying a RAR to the terminal, the terminal further sends msg3 carrying Scheduled Transmission (Scheduled Transmission) to the network device, and the network device feeds back msg4 carrying a Contention result (Contention Resolution) to the terminal to complete a Contention random access process.

As shown in fig. 3, a Media Access Control (MAC) Control Element (CE) format of the RAR includes: a Reserved bit (Reserved bit) R, a Timing Advance Command (Timing Advance Command), an Uplink scheduling (UL grant), and a Temporary Cell Radio Network Temporary Identity (TC-RNTI). Wherein, the UL grant employs a Hybrid Automatic Repeat Request (HARQ) process (process)0 for scheduling data.

The HARQ process number for the configuration grant (configured grant) is determined according to the symbol position where the scheduling is located, and taking the number of HARQ processes that the network device configures to the terminal for the configuration grant to use as 2 as an example, the HARQ process numbers for the configuration grant are 0 and 1. Thus, msg3 uses HARQ process 0, when a configured grant arrives, HARQ process 0 will be occupied by the configured grant, and then msg3 cannot be reselected, which results in msg3 decoding failure and thus random access procedure failure.

Referring to fig. 4, fig. 4 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 41 and a network device 42. The terminal 41 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 41 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 41 is not limited in the embodiment of the present invention. The network device 42 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention, only the Base Station in the NR system is taken as an example, but does not limit the specific type of base station.

The base stations may communicate with the terminals 41 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 41 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may include an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 41 to network device 42) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 42 to terminal 41). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission.

Further, an embodiment of the present invention provides an information transmission method, which is applied to a terminal side, and as shown in fig. 5, the method includes the following steps:

step 51: and under the condition that the configuration authorization and the random access process schedule the same target hybrid automatic repeat request (HARQ) process, performing random access through the target HARQ process.

For the configuration authorization transmission, the terminal has two transmission modes, one is based on RRC transmission configuration, and does not need any layer 1(level1, L1) signaling for activation and deactivation. In this transmission mode, the RRC configures at least the following parameters: a transmission cycle, an offset (offset) with respect to a System Frame Number (SFN), a time domain resource allocation, a frequency domain resource allocation, a demodulation Reference Signal (DMRS) configuration for a terminal-specific (UE-specific), a Modulation and Coding Scheme (MCS), a Transport Block (TBS), a Repetition (Repetition) Number K, a power control related parameter, and the like. Another transmission mode is based on RRC and L1 signaling simultaneously, performs transmission configuration based on RRC, and performs activation or deactivation through L1 signaling. Wherein, in the transmission mode, the RRC configures at least the following parameters: transmission period and power control related parameters. L1 signals configuration of at least the following parameters: offset with respect to one reference timing (reference timing), resource allocation in the time domain, resource allocation in the frequency domain, terminal-specific DMRS configuration, MCS and TBS, and the like.

Wherein, the HRAQ process ID of the configuration grant is related to the symbol position where the configuration grant is currently located, and assuming that the number of HARQ processes used by the configuration grant configured for the terminal by the network device is 2, the HARQ process ID used by the configuration grant is calculated according to the following formula:

HARQ Process ID＝[floor(CURRENT_symbol/periodicity)]modulo nrofHARQ-Processes

the HARQ Process ID represents the number of the HARQ Process, floor is a downward rounding operator, CURRENT _ symbol represents the CURRENT symbol position, period represents the transmission period, modulo is a modulus operator, and nrofHARQ-Process represents the number of the HARQ Processes adopted by the configuration authorization configured for the terminal by the network equipment.

Wherein, CURRENT _ symbol ═ (SFN × number of slotspersFrame × number of SymbolsPerSlot + slot number in the frame × number of SymbolsPerSlot + symbol number in the slot)

The SFN is a system frame number, the number of slots included in each system frame is denoted by the number of numberOfSlotsPerFrame, the number of symbols included in each slot is denoted by the number of symbols included in each slot, the slot number in the frame is denoted by the slot number, and the symbol number in the slot is denoted by the symbol number.

Further, step 51 may be applied to, but is not limited to, the following scenarios: and when the random access response RAR in the random access process schedules the target HARQ process, if the configuration authorization occupying the target HARQ process arrives, transmitting the uplink information scheduled by the RAR or the message III of the random access process through the target HARQ process. In this scenario, the terminal schedules a target HARQ process (e.g., HARQ process 0) at the RAR, and other configuration grants arrive, and if the configuration grants also schedule the target HARQ process, in order to avoid HARQ process collision, the terminal transmits uplink information scheduled by the RAR or a message three of a random access process through the target HARQ process.

Specifically, how the terminal avoids HARQ process collision may be implemented by, but is not limited to, the following manners, that is, when a random access response RAR in a random access process schedules a target HARQ process, if a configuration grant occupying the target HARQ process arrives, the step of transmitting uplink information scheduled by the RAR or a message in the random access process through the target HARQ process includes, but is not limited to, the following manners:

first, a configuration authorization timer (configuration grant timer) is used.

In this way, under the condition that RAR schedules a target HARQ process, a configuration authorization timer is started; and before the configuration authorization timer is overtime, if the configuration authorization occupying the target HARQ process arrives, transmitting uplink information scheduled by RAR or a message III of a random access process through the target HARQ process. In this way, during the time period of the configuration authorization timer, the terminal does not respond to the request of configuration authorization, and further responds to the request in the random access process.

Further, configuring the start timing of the authorization timer includes but is not limited to: when an RAR for scheduling a target HARQ process is received, or when a Temporary (temporal) Cell Radio Network temporal Identity (C-RNTI) for scheduling the target HARQ process is received.

Specifically, the information transmission method of the embodiment of the present invention further includes: and starting a configuration authorization timer when a target HARQ process is scheduled by receiving a temporary cell radio network temporary identifier C-RNTI. In this way, after the RAR finishes scheduling the new transmission of the message three, if the retransmission of the target HARQ process (e.g. HARQ process 0) scheduled by the temporal C-RNTI is received, the configuration authorization timer is started or restarted as well. Or, a new transmission of a target HARQ process (e.g., HARQ process 0) is further scheduled by using the temporary C-RNTI, then the configured grant timer of the target HARQ process is also started or restarted.

In this manner, step 51 includes: and before the configuration authorization timer is overtime, if the configuration authorization and the random access process schedule the same target HARQ process, performing random access through the target HARQ process. For example, when a target HARQ process is scheduled by the temporal C-RNTI, a configuration grant timer is started, and before the configuration grant timer expires, if a configuration grant occupying the target HARQ process arrives, uplink information scheduled by the RAR or a message three in the random access process is transmitted through the target HARQ process.

Mode two, skip (skips) configuration authorization

In this way, under the condition that the RAR schedules the target HARQ process or the target HARQ is occupied by the message three, if the configuration authorization occupying the target HARQ process arrives, the configuration authorization is skipped, and the uplink information scheduled by the RAR or the message three in the random access process is transmitted through the target HARQ process. In this way, if the terminal receives the process HARQ 0 scheduled by the RAR, if the terminal encounters the configuration grant and also uses the HARQ process, the terminal skips the transmission of the configuration grant.

Further, in this manner, after the step of skipping the configuration grant and transmitting the uplink information scheduled by the RAR or the message of the random access procedure through the target HARQ process, the method further includes: when the target condition is met, if the configuration authorization occupying the target HARQ process arrives, transmitting the information of the configuration authorization through the target HARQ process; wherein the target condition comprises at least one of:

receiving a message IV of the random access process, if the terminal stops skipping when receiving the mark that the msg4 competition resolving is successful;

the contention resolution timer is overtime in the contention random access process, namely the terminal stops skipping when the contention resolution timer is overtime;

the buffer area of the message three is emptied, namely the terminal stops skipping when the buffer of the msg3 is emptied;

and the HARQ buffer corresponding to the message three is emptied, namely the terminal stops skipping when the HARQ buffer corresponding to the msg3 is emptied.

Mode three, HARQ process of replacing RAR scheduling or HARQ process of replacing configuration authorization scheduling

In this way, the terminal can change the HARQ process used by RAR scheduling or change the HARQ process used by configuration authorization.

Specifically, under the condition that the configuration authorization and the random access process schedule the same target hybrid automatic repeat request HARQ process, the preset HARQ process replaces the target HARQ process scheduled by the RAR. And the preset HARQ process is the maximum number of the uplink HARQ process. For example, the HARQ process used by RAR scheduling may be changed to the largest HARQ process number available for uplink of the terminal.

Or, under the condition that the configuration authorization and the random access process schedule the same target hybrid automatic repeat request (HARQ) process, replacing the target HARQ process corresponding to the configuration authorization by the preset HARQ process. The preset HARQ process is the maximum number of the uplink HARQ process, specifically, when one HARQ process is configured and authorized to be scheduled, the preset HARQ process is the maximum number of the uplink configured HARQ processes, and when two or more HARQ processes are configured and scheduled, the preset HARQ is selected from the maximum number of the uplink configured HARQ processes from large to small. For example, the HARQ process granted for configuration may be allocated from the largest starting HARQ process number available in the uplink of the terminal.

Assuming that the number of HARQ processes available for uplink of the terminal is 0 to 7, when the HARQ process scheduled by the RAR conflicts with the HARQ process configured with the grant scheduling, HARQ process 7 may be used for RAR scheduling.

Or, when the HARQ process scheduled by RAR conflicts with the HARQ process configured with the grant scheduling, 2 HARQ processes are configured and scheduled, so that HARQ process 7 and HARQ process 6 can be used for the configured grant scheduling.

Specifically, the preset HARQ process number may be implemented by the following formula:

HARQ Process ID’＝HARQ_max-HARQ Process ID

wherein, the HARQ Process ID' represents a preset HARQ Process number, HARQ _ max is a maximum HARQ Process number that can be used by the terminal uplink, and the HARQ Process ID represents a number of a target HARQ Process before replacement.

HARQ Process ID＝[floor(CURRENT_symbol/periodicity)]modulo nrofHARQ-Processes

Wherein, floor is a rounding-down operator, CURRENT _ symbol represents the CURRENT symbol position, periodicity represents the transmission period, modulo is a modulo operator, and nrofHARQ-Processes represents the number of HARQ Processes used by the network device for the configuration authorization configured by the terminal.

In the embodiment of the invention, when the terminal receives the RAR or the temporal C-RNTI to schedule the target HARQ process, the data is taken from msg3 again and put into the target HARQ process for transmission. The step of transmitting the RAR scheduled uplink information or the message of the random access procedure through the target HARQ process may be implemented by the following examples, but is not limited to the following examples:

example one, if the HARQ process is not occupied, transmitting uplink information or data of message three scheduled by the RAR through the HARQ process; in this example, when the target HARQ process is not occupied by other data, the terminal may directly transmit the retransmitted data version.

Example two, if the HARQ process is occupied, transmitting data in the buffer area of the message three through the HARQ process; in this example, if the target HARQ process is already occupied by other data, the terminal may re-occupy the target HARQ process with the data in the buffer area of msg 3.

Further, step 51 of the embodiment of the present invention further includes: a terminal sends a message I carrying a random access request; and receiving a Random Access Response (RAR), wherein the RAR schedules a target HARQ process. The process can refer to the random access process shown in fig. 1 and fig. 2, and therefore, the description thereof is omitted here.

In the information transmission method of the embodiment of the invention, the terminal can carry out the random access process through the target HARQ process when the random access process conflicts with other HARQ processes which are configured with authorized scheduling, thereby ensuring the normal operation of the random access process when the HARQ processes conflict and avoiding the problem of the failure of the random access process caused by the conflict of the HARQ processes.

The above embodiments respectively describe in detail the information transmission methods in different scenarios, and the following embodiments further describe the corresponding terminals with reference to the accompanying drawings.

As shown in fig. 6, the terminal 600 according to the embodiment of the present invention can implement details of performing a random access method through a target HARQ process under the condition that a configuration authorization and a random access process schedule the same target HARQ process, and achieve the same effect, where the terminal 600 specifically includes the following functional modules:

a transmission module 610, configured to perform random access through a target hybrid automatic repeat request HARQ process under the condition that the configuration grant and the random access process schedule the same target HARQ process.

Wherein, the transmission module 610 includes:

and the transmission submodule is used for transmitting uplink information scheduled by the RAR or a message III of the random access process through the target HARQ process if the configuration authorization occupying the target HARQ process arrives when the target HARQ process is scheduled by the random access response RAR in the random access process.

Wherein, terminal 600 includes:

and the starting module is used for starting the configuration authorization timer when a target HARQ process is scheduled by the temporary cell radio network temporary identifier C-RNTI.

and the first transmission unit is used for skipping the configuration authorization if the configuration authorization for occupying the target HARQ process arrives under the condition that the RAR schedules the target HARQ process or the target HARQ is occupied by the message III, and transmitting the uplink information scheduled by the RAR or the message III in the random access process through the target HARQ process.

Wherein, the transmission submodule also includes:

a second transmission unit, configured to transmit configuration grant information through the target HARQ process if a configuration grant occupying the target HARQ process arrives when the target condition is satisfied; wherein the target condition comprises at least one of:

receiving a message IV of a random access process;

the contention resolution timer is overtime in the contention random access process;

the buffer area of the message III is emptied;

and the HARQ buffer corresponding to the message three is emptied.

Wherein, the transmission submodule is specifically configured to:

if the HARQ process is not occupied, transmitting uplink information or data of a message III scheduled by RAR through the HARQ process;

or,

and if the HARQ process is occupied, transmitting data in the buffer area of the message III through the HARQ process.

Wherein, under the condition that the configuration authorization and the random access process schedule the same target HARQ process, the terminal 600 further includes:

the first replacement module is used for replacing a target HARQ process scheduled by the RAR with a preset HARQ process;

or,

and the second replacement module is used for replacing the preset HARQ process with the target HARQ process corresponding to the configuration authorization.

And the preset HARQ process is the maximum number of the uplink HARQ process.

Wherein, the terminal 600 further includes:

the sending module is used for sending a message I carrying the random access request;

and the receiving module is used for receiving a Random Access Response (RAR), wherein the RAR schedules a target HARQ process.

It is worth pointing out that the terminal of the embodiment of the present invention can perform the random access process through the target HARQ process when the random access process conflicts with other HARQ processes configured with the authorized scheduling, so as to ensure the normal operation of the random access process when the HARQ processes conflict, and avoid the problem of the failure of the random access process caused by the HARQ process conflict.

It should be noted that the division of the modules of the network device and the terminal is only a logical division, and the actual implementation may be wholly or partially integrated into one physical entity, or may be physically separated. And these modules can be realized in the form of software called by processing element; or may be implemented entirely in hardware; and part of the modules can be realized in the form of calling software by the processing element, and part of the modules can be realized in the form of hardware. For example, the determining module may be a processing element separately set up, or may be implemented by being integrated in a chip of the apparatus, or may be stored in a memory of the apparatus in the form of program code, and the function of the determining module is called and executed by a processing element of the apparatus. Other modules are implemented similarly. In addition, all or part of the modules can be integrated together or can be independently realized. The processing element described herein may be an integrated circuit having signal processing capabilities. In implementation, each step of the above method or each module above may be implemented by an integrated logic circuit of hardware in a processor element or an instruction in the form of software.

For example, the above modules may be one or more integrated circuits configured to implement the above methods, such as: one or more Application Specific Integrated Circuits (ASICs), or one or more microprocessors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs), etc. For another example, when some of the above modules are implemented in the form of a Processing element scheduler code, the Processing element may be a general-purpose processor, such as a Central Processing Unit (CPU) or other processor that can invoke the program code. As another example, these modules may be integrated together, implemented in the form of a system-on-a-chip (SOC).
