Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to methods, mobile stations and network devices for service transmission.

The application field of future cellular network systems is extended from traditional human-to-human communication to human-to-object or object-to-object communication. In the conventional Long Term Evolution (LTE) system, related studies such as Machine Type Communication (MTC) service and Vehicle to X (V2X) service have already started. , MTC services are also called the Internet of Things.

In the future 5G system, there will be the following typical service scenes correspondingly. High throughput, high capacity, high spectral efficiency Mobile Broadband (MBB) services such as Voice over LTE (VoLTE) services, low power consumption Massive MTC (Massive MTC) services, low latency and There are ultra-reliable MTC (Low-Latency & Ultra-Reliable MTC) services, such as V2X services. In these scenes, periodic service transmission becomes one typical service transmission method.

On the other hand, with the development of communication technology, the LTE system can provide many kinds of scheduling schemes such as dynamic scheduling, static scheduling and semi-persistent scheduling (SPS). there is

Here, semi-static scheduling is also called semi-persistent scheduling, that is, allocating resources to users according to a certain period without having to indicate it by scheduling signaling in all resource allocations within the period. Compared to dynamic scheduling, the flexibility of such a scheduling method is somewhat poor, but because the control signaling overhead is small, it is suitable for services with unexplained burst characteristics and rate reservation requirements, such as the above VoLTE services and V2X services. fit. Depending on needs, different SPS resources usually need to be deployed for different services or different service types.

In the prior art, a user generally transmits only one service type of service in a certain time period, and depending on the service type transmitted by the user, the device on the network side will create a physical downlink control channel (PDCCH: Allocate one SPS resource to it by Physical Downlink Control Channel). When the service transmission is completed, the network side device releases the SPS resource by PDCCH. If the user transmits a service of a new service type, the device on the network side will send PDCCH again to allocate new SPS resources. It should be noted that if a service changes its reception cycle or transmission cycle, or changes the size of data packets during service transmission, according to the needs of a service, the SPS resource must be released and reallocated according to the above process. There is more. The above process will cause occupation of a lot of PDCCH resources.

It should be noted that in some special cases of the prior art, besides transmitting the current service, the user may transmit services of other service types at one time. In this case, a device on the network side generally instructs the configuration of SPS resources of the current subframe temporarily using a dynamic scheduling scheme through the PDCCH. New services are also periodic, and the configuration of SPS resources in the next subframe still needs to be indicated by the PDCCH using a dynamic scheduling scheme according to the requirements. This scheme can solve the problem of SPS resource configuration in a timely manner, but the SPS resource configuration is performed in each subframe, which causes occupation of a lot of PDCCH resources.

FIG. 1 is a schematic diagram of a communication system for service transmission in one embodiment of the present invention. As shown in FIG. 1, the communication system 100 includes a network device 102, which may include multiple antennas, such as antennas 104, 106, 108, 110, 112, and 114. FIG. Network device 102 also includes a transmitter chain and a receiver chain, which, as understood by those skilled in the art, are multiple components associated with transmitting and receiving signals (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.).

Network device 102 may communicate with multiple terminals (eg, terminal 116 and terminal 122). However, it should be understood that network device 102 may communicate with any number of terminals similar to terminals 116 or 122 . Terminal devices 116 and 122 may be, for example, mobile phones, smart phones, laptop computers, portable communication devices, pocket computing devices, satellite radio devices, global positioning systems, PDAs and/or any other devices for communicating with wireless communication system 100. It may be a device.

As shown in FIG. 1, terminal 116 communicates with antennas 112 and 114, where antennas 112 and 114 transmit information to terminal 116 over forward link 118 and forward link 120 to terminal 116. Information is received from the terminal device 116 . Note that terminal 122 communicates with antennas 104 and 106, where antennas 104 and 106 transmit information to terminal 122 over forward link 124 and receive information from terminal 122 over reverse link 126. receive.

For example, in a Frequency Division Duplex (FDD) system, for example, forward link 118 utilizes a different frequency band than reverse link 120, and forward link 124 utilizes a different frequency band than reverse link 126. can do.

Also, for example, in Time Division Duplex (TDD) and Full Duplex systems, forward link 118 and reverse link 120 may use a common frequency band and forward link 124 and reverse link 124 may use a common frequency band. Directional links 126 may use a common frequency band.

Each antenna (or set of antennas) and/or region for communication is referred to as a sector of network device 102 . For example, the antenna sets are configured to communicate with terminals in sectors of the coverage area of network device 102 . In the course of network device 102 communicating with terminals 116 and 122 over forward links 118 and 124, respectively, the transmit antennas of network device 102 employ beamforming to reduce the ratio of noise on forward links 118 and 124 to can be improved. Note that compared to a scheme in which a network device transmits signals to all terminals via a single antenna, network device 102 transmits signals to terminals 116 and 122 that are randomly distributed over the coverage-relevant area with beamforming. Thus, mobile devices in adjacent cells experience less interference.

At any given time, network device 102, terminal 116, or terminal 122 may be a wireless communication transmitter and/or a wireless communication receiver. When transmitting data, the wireless communication transmitting device may code the data in order to transmit the data. Specifically, a wireless communication transmitting device obtains (eg, generates, receives from another communication device, or stores in a storage device) a predetermined number of data bits to be transmitted over a channel to a wireless communication receiving device. etc.). Such data bits can be included in a transport block (or multiple transport blocks) of data, and the transport block is segmented to generate multiple code blocks.

The communication system 100 is a public mobile communication network (PLMN: Public
Land Mobile Network), D2D network, M2M network, V2V network, V2X network, or other networks, and FIG. 1 is an exemplary simplified diagram, and the network further includes other network devices. not shown in FIG.

The technical solutions according to the embodiments of the present invention are applicable to conventional cellular communication systems, such as Global System for Mobile Communications (GSM), Wideband Code Division Multiple Access (WCDMA), It can be applied to systems such as Long Term Evolution (LTE), and the supported communication mainly corresponds to voice and data communication. Usually, the number of possible connections of one legacy base station is limited and easy to implement.

The next-generation mobile communication system supports traditional communication as well as machine-to-machine (M2M) communication, or MTC communication. Projections show that by 2020, there will be 50-100 billion MTC devices connected to the network, far exceeding the number of traditional connections. For M2M type services, the demands on the network are very different due to the variety of service types.

In the LTE system, the SPS mechanism mainly provides a scheduling method called semi-static scheduling (SPS) for periodic service transmission, such as VoLTE service, which is the most representative example. A side device, e.g., a base station, first configures the mobile station to correspond to SPS resources via Radio Resource Control (RRC) signaling, e.g., sets of multiple sets for SPS. Configure resource allocation parameters to . The resource allocation parameters may include transmission period, transport block size, position and number of transport blocks, transmission power control parameters, number of Hybrid Automatic Repeat reQuest (HARQ) processes, and the like. Then, if needed, the mobile stations are actually assigned a set of resource allocation parameters to use over the PDCCH, and once the resource allocation parameters are activated, they are valid periodically. In the LTE system, since the data packet size of VoLTE services are both dozens of bytes and the period is constant, the SPS mechanism can be used to save control signaling to some extent.

Specifically, it is an operation flowchart of the SPS shown in FIG. In FIG. 2, in the resource allocation parameters assigned to the mobile station, the transmission period is 20ms, and the figure shows three transmission blocks (where the number of transport blocks is an example). Since the PDCCH is not transmitted after the resource allocated to the mobile station is activated, the transmission period, transport block size, etc. cannot be changed, and the resource is only released and then activated again. Configure again.

In the future LTE development and 5G system, there will be more and more periodic services, and more and more scenarios for using the SPS mechanism, specifically but not limited to the following scenarios:

As scene 1, in the MBB service, multiple types of periodic services can be mixed and transmitted, for example, VoLTE service, real-time communication heartbeat data, etc. can be mixed and transmitted. In these scenes, the network triggers one or more SPS configurations or resource allocation schemes, ie, allocates a set of resource allocation parameters, and updates resource allocation parameters if necessary.

As scene 2, in the Massive MTC service with low power consumption, the network needs to perform data transmission periodically, the mobile station also needs to perform data transmission periodically, and the data packet size may be changed. There is

Scene 3 is low-delay and high-request Internet services, especially in V2X service scenes, where it is necessary to periodically broadcast the vehicle status in the network, whether it is a vehicle or a network, and the data packet size is variable. .

The above three types of scenes may correspond to service request changes shown in FIG. For example, a request for the SPS configuration of one service is shown in transmission blocks 1-3 and the transmission period is T1, and after the service request is changed, the request is changed as shown in transmission blocks 4-6. Moreover, the transmission period is T2. It should be noted that the size and number of transport blocks are illustrative here, and the embodiments of the present invention are not limited to these.

First, the resource allocation parameter sets and resource allocation parameters used for semi-static scheduling in the embodiments of the present invention are described in detail.

In an embodiment of the present invention, the resource allocation parameters are used for periodic resource scheduling (or periodic resource allocation), or the resource allocation parameters are parameters related to periodic resource scheduling. good too. Illustratively, the resource allocation parameters in each resource allocation parameter set include transmission period, transport block size, transport block number, transport block location, uplink power control parameter, modulation and coding scheme (MCS). Coding Scheme, ) and number of Hybrid Automatic Repeat reQuest (HARQ) processes.

Specifically, the transmission period may be a time interval in which the mobile station (or network device) transmits (transmits or receives) data or information twice consecutively for the same service. As an example, the transmission period may be 20 ms, 10 ms or 5 ms, but is not limited thereto.

In the embodiment of the present invention, the target of data or information transmission (transmission or reception) of a mobile station (or network device) may be a network device or another mobile station. , the invention is not limited thereto. When a mobile station transmits data or information to a network device, the transmission period may be an uplink transmission period. The transmission period may be a downlink transmission period when the mobile station receives data or information transmitted by a network device.

In an embodiment of the present invention, the transport block size is the size of a time-frequency resource block occupied by one data transmission of a mobile station (or network device). For example, a transport block is composed of M code lengths in the time domain and N resource blocks (RBs) in the frequency domain.

In addition, the transfer block size in the embodiment of the present invention can correspond to the size of the data packet to be transmitted each time in the service. Preferably, a transport block can bear a data packet that is transmitted at one time.

In an embodiment of the present invention, the number of transport blocks is the number of times a service can be transmitted in succession when using the same SPS configuration for service transmission. The number of transport blocks can be indicated by the number of consecutive Transmission Time Intervals (TTIs) used for the transmission service, and embodiments of the present invention are not limited thereto.

In an embodiment of the present invention, the position of the transport block is the time domain and frequency domain position of the transport block, eg, which code the transport block starts with, which RB it starts with, and so on.

In an embodiment of the present invention, the resource allocation parameter set may further include a modulation coding scheme MCS used by the modulated signal during service transmission.

The uplink power control parameter is a parameter related to the transmission power used for one or more transmissions of data or information of the mobile station. The parameter may be, but is not limited to, the maximum transmit power that the mobile station can use.

Currently, the stop-and-wait HARQ protocol is normally used, so the corresponding HARQ process number needs to be configured. In the process of waiting for feedback information of a HARQ process, other idle processes can be used to transmit data packets. The minimum RTT (Round Trip Time) of HARQ is defined as the time it takes for one data packet transmission process, one data packet is transmitted by the transmitting side, received and processed by the receiving side, and results are fed back ACK/NACK signaling. , the transmitting side demodulates the ACK/NACK signal and then decides to retransmit or transmit a new data packet in the next frame. The number of HARQ processes is closely related to the minimum HARQ RTT time. For Frequency Division Duplexing (FDD), the number of HARQ processes is equal to the number of subframes included in the HARQ minimum RTT time, and for Time Division Duplexing (TDD), the HARQ is equal to the number of subframes in the same transmission direction included in the HARQ minimum RTT time.

Note that the specific parameters included in the resource allocation parameters listed above are exemplary, but the present invention is not limited to these, and other parameters related to periodic resource scheduling or periodic resource allocation is also included in the protection scope of the present invention.

In addition, in the embodiment of the present invention, the types of resource allocation parameters included in one resource allocation parameter set are not particularly limited. For example, one resource allocation parameter set includes all the resource allocation parameters listed above. Alternatively, one resource allocation parameter set may include some of the resource allocation parameters described above, and each resource allocation parameter of "N resource allocation parameter sets" described later The types and number of resource allocation parameters included in the sets may be the same or different, and the present invention is not limited thereto.

FIG. 4 shows a flowchart of a method 400 for service transmission in one embodiment of the invention. Method 400 is executed between a network device and a mobile station and includes the following steps.

Correspondingly, the mobile station receives second control signaling sent by the network device.

Here, both the first resource allocation parameter set and the second resource allocation parameter set are resource allocation parameter sets for performing SPS allocated to the mobile station by the network device. Every resource allocation parameter set includes at least one resource allocation parameter.

The second control signaling may be higher layer control signaling. Preferably, the second control signaling is Radio Resource Control (RRC) signaling.

In one preferred embodiment, network devices and mobile stations include a one-to-one correspondence between negotiated sets of SPS configurations (resource allocation parameter sets) and index identifiers, wherein: The one-to-one correspondence between the plurality of resource allocation parameter sets and the plurality of index identifiers includes the one-to-one correspondence between N resource allocation parameter sets and N index identifiers. That is, a network device and a mobile station contain a one-to-one correspondence between N resource allocation parameter sets and N index identifiers. If the second control signaling contains N index identifiers, it can indicate N resource allocation parameter sets. Also, the third control signaling and the first control signaling can be indicated by an index identifier when indicating the first resource allocation parameter set and the second resource allocation parameter set, respectively.

In addition, in the embodiment of the present invention, the resource allocation parameter set indicated by the second control signaling may include some of the resource allocation parameters listed above. Specific contents of other parameters are transmitted by the first control signaling in S405.

At S403, the mobile station transmits the current service using the first resource allocation parameter set in the manner of semi-static scheduling SPS. That is, the mobile station transmits the current first service using the first resource allocation parameter set.

In S404, if the mobile station's currently transmitting service requirement is changed, the network device determines a second resource allocation parameter set according to the change in the mobile station's service requirement.

Specifically, the network device determining the second resource allocation parameter set according to changes in the service requirements of the mobile station includes the following cases.

In the first case, for the request change of the currently transmitting service, specifically, the network device transmits the request-modified first service according to the change of the currently transmitting first service request.

Correspondingly, the first control signaling sent by the network device of S405 to the mobile station indicates that the mobile station uses the second resource allocation parameter set instead of the first resource allocation parameter set in the manner of the SPS to request It is used to indicate transmission of the modified first service.

A specific example is shown in FIG. 5, the first service is transmitted by transmission blocks 1, 2 and 3 before the request is changed. As a request change, the data packet size may be increased and the transmission cycle may be decreased. After being modified, the first service is transmitted by transmission blocks 4, 5 and 6. FIG.
