Description

Multi-service multiplexing information transmission method and device, and time division duplex communication system

Technical field

The present invention relates to the field of communications technologies, and in particular, to a multi-service multiplexed information transmission method and apparatus, and a Time Division Duplex (TDD) communication system.

Background technique

With the development of communication technology, research on the fifth generation (5G) communication technology has begun. In the 5G research, the following three high-level application scenarios are involved: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable low-latency communication (uRLLC). , ultra-reliable low latency communication). A terminal device (also referred to as a user device) is not limited to a human-oriented terminal type such as a mobile phone. Terminal devices for the Internet of Things, such as sensors, machines, and robots, will be applied on a large scale. On the network side, the base station also expects to be able to support different types of user scenarios or service types at the same time.

The signal format can be different for each application scenario. For example, for uRLLC services, low latency is a key factor. Therefore, it is more desirable to use a short Transmission Time Interval (TTI), which may be 1/5 of the current Long Term Evolution (LTE) system. 1/10. For the mMTC service, it is usually desirable to use an inexpensive transceiver, which will use a crystal with low precision, which means that the synchronization accuracy is not high, and the use of a longer symbol length can reduce the timing accuracy requirement. For eMBB services, the downlink and uplink ratios may change more dynamically than during the fourth generation (4G) communication period, taking a shorter TTI than the TTI of the LTE system, such as 1/2 of the TTI in the LTE system. Increase the flexibility of scheduling.

In summary, in order to efficiently support various application scenarios, different service classes preferably use different signal formats, such as symbol length, subcarrier spacing, cyclic prefix length (CP), TTI, and the like.

In the case of rich frequency domain resources, operators can use different frequency bands to operate different services. For example, for mMTC services, a wide range of low frequency bands, such as the 700 MHz band, can be used. For the eMBB service, a frequency band of about 4 GHz and a frequency band of 6 GHz or higher (for example, a frequency band of about 30 GHz) can be used. For the uRLLC service, a frequency band between 5 GHz and 6 GHz can be used. However, in terms of the economics of network deployment, operation, and maintenance, supporting multiple services in a continuous frequency band is a new requirement for 5G systems.

The problem faced here is that for a transceiver in a TDD system, if the radio frequency (RF, Radio Frequency) front end of the transceiver is not changed, true simultaneous uplink and downlink transmission cannot be achieved. In addition, the sub-band filter in the digital domain also has difficulty filtering out the uplink-to-downlink interference. Therefore, downlink and uplink synchronization are necessary for the services of the different user scenarios described above, and are in the same contiguous spectrum resource. Different services, either do downlink transmission together or do uplink transmission together.

On the other hand, the uplink and downlink ratios expected by the services of different user scenarios are different. In addition, the TTIs of different services may also be different, which may result in no transmission of some subframes, which means that wireless resources are wasted. Therefore, a more efficient way to improve the spectrum utilization of multi-service multiplexing is needed.

It should be noted that the above description of the technical background is only for the purpose of facilitating a clear and complete description of the technical solutions of the present invention, and is convenient for understanding by those skilled in the art. The above technical solutions are not considered to be well known to those skilled in the art simply because these aspects are set forth in the background section of the present invention.

Summary of the invention

The use of a single continuous band to support different services is one of the requirements of future 5G systems.

The inventor has found that for a TDD system, when a single continuous spectrum is used for multiple service multiplexing, it is necessary to maintain uplink and downlink consistency of different services, that is, simultaneously perform uplink transmission or downlink transmission for each service to avoid uplink and downlink. interference. On the other hand, due to the different nature of different services, such as different TTIs, the expected uplink and downlink ratios are also different. Consistent conversion of uplink and downlink will result in waste of wireless resources.

detailed description

The foregoing and other features of the present invention will be apparent from the The specific embodiments of the present invention are disclosed in the specification and the drawings, which are illustrated in the embodiment of the invention The invention includes all modifications, variations and equivalents falling within the scope of the appended claims.

In the present application, a base station may be referred to as an access point, a broadcast transmitter, a Node B, an evolved Node B (eNB), etc., and may include some or all of their functions. The term "base station" will be used herein. Each base station provides communication coverage for a particular geographic area. The term "cell" can refer to a base station and/or its coverage area, depending on the context in which the term is used.

In this application, a mobile station or device may be referred to as a "User Equipment" (UE). The UE may be fixed or mobile, and may also be referred to as a mobile station, terminal, access terminal, subscriber unit, station, etc.; in a 5G system, it may also include a machine type communication terminal, a low latency, high reliability type terminal, and the like. The UE may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, etc.; in a 5G system, there may be robotic (robot-like) terminals, automobiles, sensors, etc. .

Seven uplink and downlink ratios are given in the LTE standard (36.211). For the future 5G system, the uplink and downlink ratio will adopt a new method. Although 3GPP has just started the "NR" (New Radio) standardization work for 5G, the TDD frame structure adopted by NR and the uplink-downlink ratio have not been determined. It is foreseeable that the future 5G system will adopt an ultra dense network, and the business changes of each cell will be faster or more diverse, which may lead to more kinds of uplink and downlink matching requirements.

In general, the downlink service will account for more than the uplink service. Figure 1 is a schematic diagram of the uplink and downlink ratio. As shown in Figure 1, for example, the ratio of downlink services to uplink services is 3:1.

For new application scenarios, such as mMTC services, the main application areas include wide-area coverage sensor networks, where downlink broadcast and scheduling information may be very small, and nodes periodically report data after being statically scheduled, and uplink services occupy absolute leading.

FIG. 2 is another schematic diagram of the uplink-downlink ratio, showing the possible scenarios of the uplink and downlink configurations suitable for the mMTC service. The uplink TTI may be much longer than the downlink TTI, or multiple uplink TTIs that are equal in length to the downlink TTI may be used.

FIG. 3 is a schematic diagram of comparing the uplink and downlink of the eMBB service and the mMTC service. As shown in FIG. 3, in a certain area at a certain time, the optimal uplink-downlink ratios of different services are generally inconsistent, regardless of the basis. That kind of business. The multiplexing method shown in Figure 3 above is not possible to work in a continuous spectrum.

4 is another schematic diagram for comparing the uplink and downlink of the eMBB service and the mMTC service, and FIG. 5 is another schematic diagram for comparing the uplink and downlink of the eMBB service and the mMTC service, and FIG. 4 and FIG. The situation after the adjustment is made up and down.

As shown in Figure 4 or 5, because the service requirements do not match the uplink and downlink ratios, there may be different service TTIs, which may result in no service transmission in some subframes. For example, "N" in Figures 4 and 5 indicates that there is no traffic transmission, which means that wireless resources are wasted.

The above only uses two kinds of services as an example to illustrate the problems faced by multiple services. For three or more kinds of service multiplexing, there are also such problems, and more resources are wasted. Therefore, a more efficient way to improve the spectrum utilization rate of multi-service multiplexing is needed.

It should be noted that in the above figures, the guard interval GP of the uplink and downlink conversion is omitted. The guard interval may be between the downlink TTI and the uplink TTI, or may exist in a TTI or a subframe, such as a self-contained frame shown in FIGS. 12 to 23 and the like.

Example 1

Embodiments of the present invention provide a multi-service multiplexed information transmission method, which is applied to a TDD communication system. The first service using the first signal format and the second service using the second signal format are respectively allocated resources; for example, the base station may schedule the first service to occupy a part of the sub-band resources and the second after the second service is idle for a period of time. The business occupies another part of the sub-band resource.

FIG. 6 is a schematic diagram of a multi-service multiplexed information transmission method according to an embodiment of the present invention. As shown in FIG. 6, the multi-service multiplexed information transmission method includes:

Step 601: In a case that the resource allocated to the second service is not used by the second service, the base station controls the first service to occupy the resource allocated to the second service.

In this embodiment, the first signal format or the second signal format may include one or more of the following: symbol length, subcarrier spacing, cyclic prefix length, TTI, etc.; but the invention is not limited thereto. The first service or the second service belongs to one of the following service categories: eMBB, mMTC, uRLLC; however, the present invention is not limited thereto.

For example, for a certain service category, it may be further divided into multiple sub-service categories according to different signal formats. For example, the eMBB service can be classified into a first type of eMBB service, a second type of eMBB service, ..., and the like. Therefore, two services with different signal formats can be considered to belong to different service categories.

The following is a convenient description, and only the first service and the second service are taken as an example; however, the present invention is not limited thereto, and the case of more than two services can be similarly processed.

In this embodiment, the first service may be controlled by the base station to occupy the resource allocated to the second service, but the present invention is not limited thereto. For example, the operation may be performed by other devices or entities on the network side, for example, The sending node, the relay unit, the centralized processing unit, and the like; or in some scenarios, the user equipment itself may control the operation.

For convenience of description, the present embodiment only uses the base station to perform resource control as an example for description.

In this embodiment, the user equipment that performs the first service transmission and the user equipment that performs the second service transmission may be different user equipments; for example, UE1 performs transmission of mMTC service, UE2 performs transmission of uRLLC service; or UE1 performs For the transmission of a class of mMTC services, UE2 performs the transmission of a second type of mMTC service. Alternatively, the user equipment that performs the first service transmission and the user equipment that performs the second service transmission may also be the same user equipment; for example, the transmission of the mMTC service and the transmission of the eMBB service are simultaneously performed in the UE1; or simultaneously in the UE1. Transmission of the first type of mMTC service and transmission of the second type of mMTC service. In addition, there can be more UEs for multi-service transmission.

In this embodiment, the base station may be a macro base station (for example, an eNB), and a macro cell (for example, a macro cell) generated by the macro base station may provide a service for the user equipment; or the base station may also be a micro base station, and the micro base station generates a micro area. (For example, Pico cell or small cell) can provide services for user equipment. The present invention is not limited thereto, and a specific scenario can be determined according to actual needs.

The following describes how to configure resources for multiple services. In this embodiment, the resource may include one or more of the following: a time domain resource, a frequency domain resource, and an airspace resource. The following is a schematic description of a frequency domain resource (for example, a subband resource).

In this embodiment, in order to better support multiple services and improve flexibility, enhancement may be performed based on Orthogonal Frequency Division Multiplexing (OFDM). For example, filter-OFDM technology can use multiple filters to obtain different frequency domain resources (such as sub-band resources), while still using OFDM in a certain sub-band. However, the present invention is not limited thereto. For example, a filter bank multi-carrier (FBMC) technique or a new waveform technique such as Universal Filtered Multi-Carrier (UFMC) may be used.

FIG. 7 is a schematic diagram of a frame structure of a resource including multiple services according to an embodiment of the present invention. As shown in FIG. 7, for example, subband 1 is a resource for transmitting service 1, and subband 2 is used for transporting service 2. The resource, subband 3 is a resource for transmitting service 3. As shown in FIG. 7, the subcarrier spacing, the symbol length, the CP length, the TTI, and the like of the subband 1, the subband 2, and the subband 3 may be different, that is, the signal formats used by the service 1, the service 2, and the service 3 are different. To reduce mutual interference between sub-bands, a bandpass filter can be used and a frequency domain guard interval can be introduced.

FIG. 8 is a schematic diagram of multi-service resource control according to an embodiment of the present invention, showing a first service and a second service The situation in which resources are allocated. As shown in FIG. 8, one TDD frame may include a downlink subframe "D", an uplink subframe "U", and a protection period "G". FIG. 8 illustrates a case of one frame unit, and here, a TTI of two services is assumed. It is different, and the symbol length, subcarrier spacing, and the like in each subframe are also generally different. The subbands occupied by the two services are separated by filters, which are not shown in Fig. 8 for the sake of simplicity. The description of this figure is also applicable to multi-service reuse with other terminology but consistent connotations.

FIG. 9 is another schematic diagram of multi-service resource control according to an embodiment of the present invention, showing a case where resources of the first service and the second service are controlled to be changed. As shown in FIG. 9, there are, for example, three frame units, wherein for the second frame unit, the resource allocated to the second service (as shown by the DGUU of the second frame unit in FIG. 9) is not used by the second In the case of service usage, these time domain resources can be occupied by the first service.

In one embodiment, as shown in FIG. 9, such "occupation" will last for at least one frame unit in the time domain, and the first service will not exit the frequency domain resource (eg, subband before the end of the frame unit). Occupation of resources).

FIG. 10 is another schematic diagram of multi-service resource control according to an embodiment of the present invention, showing another case where resources of the first service and the second service are controlled to be changed. As shown in FIG. 10, in the case that resources allocated to the second service (as indicated by the DDD of the second frame unit in FIG. 10) are not used by the second service, the time domain resources may be used by the first service. Occupied.

In another embodiment, as shown in FIG. 10, such "occupation" may not have to last one frame unit in the time domain. For example, once the second service is idle, the first service can start to occupy without having to be a frame unit. For the unit. Similarly, it is also possible to exit from the frame without waiting for the end of the entire frame unit, thereby making it possible to occupy resources more flexibly.

In this embodiment, resources may be allocated for multiple services in advance. For example, an operator or a system may be predefined: a first service adopting a first signal format is allocated with certain resources, and a second service using a second signal format is allocated. There are other resources. In addition, resources may also be allocated semi-statically for multiple services by the base station, and such resource allocations remain unchanged for a certain period of time. The present invention is not limited to this. Hereinafter, a base station allocates resources for multiple services and dynamically or semi-dynamically controls changes of resources as an example.

FIG. 11 is another schematic diagram of a multi-service multiplexed information transmission method according to an embodiment of the present invention. As shown in FIG. 11, the multi-service multiplexed information transmission method includes:

Step 1101: The base station separately allocates resources for the first service adopting the first signal format and the second service adopting the second signal format.

For example, as shown in FIG. 7, subband 1 is assigned for the first service, subband 2 is assigned for the second service, and so on.

Step 1102: If the resource allocated to the second service is not used by the second service, the base station controls the first service to occupy the resource allocated to the second service.

For example, as shown in FIG. 9 and FIG. 10, the first service may occupy resources originally allocated to the second service.

As shown in FIG. 11, the information transmission method of the multi-service multiplexing may further include:

Step 1103: The base station broadcasts information that the first service occupies resources allocated to the second service.

In this embodiment, the base station can broadcast information such as the occupancy status and the identifier of the occupied sub-band. Therefore, the user equipment that performs the second service transmission can be informed that the corresponding sub-band resource of the second service has been occupied by other services.

As shown in FIG. 11, the multi-service multiplexing information transmission method may further include:

Step 1104: The base station receives a request for the second service to use the resource occupied by the first service (which may be referred to as a release request);

Step 1105: The base station controls the first service to release the resource allocated to the second service.

In this embodiment, in the case that the second service is required, the first service may return the occupied resource (that is, the resource originally allocated to the second service) to the second service.

Thus, in a case where the resource allocated to the second service is not used by the second service, the first service may temporarily occupy the resource allocated to the second service; and in the case where the second service requires, the first The service releases the occupied resources. Not only can meet the needs of multi-service scenarios in TDD systems, but also can increase the utilization rate of wireless resources.

The resource control process of the present invention has been schematically described above, and the frame structure of the present invention will be further described below.

In this embodiment, a self-contained frame may be used, which includes both resources for uplink transmission and resources for downlink transmission. Therefore, even if urgent information needs to be transmitted, the fast response on the base station side or the terminal side can be ensured, and the requirements of different scenarios (such as the requirement of low latency of the uRLLC service) can be met.

Figure 12 is a schematic illustration of a self-contained frame in accordance with an embodiment of the present invention. As shown in FIG. 12, not only a downlink part but also an uplink part is included in a downlink (DL) subframe, and the uplink part is used for, for example, fast feedback of ACK/NACK, channel status information (CSI, channel status information), or channel. The transmission of a sounding signal (Channel Sounding Signal), etc., referred to herein as a downlink subframe, is based on the downlink corresponding to its data transmission portion. As shown in FIG. 12, not only the uplink part but also the downlink part is included in the uplink (UL) subframe. In part, the downlink part is used for, for example, fast feedback of ACK/NACK, transmission of fast control signaling, etc., and the uplink subframe is referred to as an uplink corresponding to the data transmission part thereof.

It is to be noted that FIG. 12 only schematically shows the case of a self-contained frame, but the present invention is not limited thereto; the specific structure regarding the self-contained frame can be determined according to actual conditions. Furthermore, other terminology may be used for the "self-contained frame" in this embodiment, as long as it includes both resources for uplink transmission and resources for downlink transmission, and is applicable to the present invention.
