Description

Data transmission method and device for flexible duplex system

Technical field

The present application relates to communication technologies, and in particular, to a data transmission method and device for a flexible duplex system.

Background technique

With the increase of the asymmetry of the uplink and downlink services in the communication system and the changing characteristics of the uplink and downlink services over time, the flexible duplex technology is applied. The flexible duplex technology considers the growth of the total traffic and the asymmetric characteristics. The uplink and downlink resources can be adaptively allocated according to the distribution of uplink and downlink services, thereby effectively improving system resource utilization to meet future network requirements.

The flexible duplex technology configures a part of the frequency band in the frequency division duplex (FDD) system to be a flexible frequency band. The flexible frequency band is allocated to the uplink transmission or the downlink transmission, so that the uplink and downlink spectrum resources are matched with the uplink and downlink service requirements. Thereby improving spectrum utilization. For example, when the downlink traffic in the network is higher than the uplink traffic, the network may configure the frequency band originally used for uplink transmission as the frequency band used for downlink transmission. In the flexible frequency band, there may be cross-link interference on some resources, that is, the terminal equipment of the first cell and the terminal equipment of the second cell simultaneously transmit in different directions on the resource, and interference occurs between each other. In the prior art, any one of the first cell and the second cell performs interference measurement on the preset measurement resource, and reports the interference measurement result to the base station, where the base station compares the terminal device of the first cell according to the interference measurement result. The terminal device of the second cell performs scheduling.

The 5G network will focus on the user experience to achieve more personalized and diversified business applications, and the demand for uplink and downlink traffic varies greatly from service to service. Traditional FDD systems are difficult to better match the diverse business needs of 5G networks. Therefore, the flexible duplex technology is applied. The flexible duplex technology considers the growth of the total traffic and the asymmetric characteristics. It can adaptively allocate uplink and downlink resources according to the distribution of uplink and downlink services, and effectively improve the utilization of system resources.

The flexible duplex technology configures a part of the frequency band of the FDD system as a flexible frequency band, which can be flexibly allocated to the uplink transmission or the downlink transmission according to the requirements of the uplink and downlink services, so that the uplink and downlink spectrum resources are matched with the uplink and downlink service requirements, thereby Improve spectrum utilization. For example, when the downlink traffic in the network is higher than the uplink traffic, the network may configure the frequency band originally used for uplink transmission as the frequency band used for downlink transmission.

In a flexible duplex scenario, terminal devices of two neighboring cells may perform data transmission on the same resource at the same time, if the terminal device of the first cell and the terminal device of the second cell simultaneously perform different directions on the resource. For example, the terminal device of the first cell performs uplink transmission on the resource, and the terminal device of the second cell performs downlink transmission on the cell, and the interference occurs due to different transmission directions of the two cells, and the interference occurs. Also known as cross-link interference or cross-slot interference.

The terminal device of the second cell performs scheduling. However, for the terminal device, the terminal device does not know how the base station performs data scheduling.

Step S102: The terminal device performs interference measurement according to the first indication information.

In an implementation manner, the terminal device sends the interference measurement signal according to the first indication information, where the terminal device may be the first terminal device connected by the first network device. The terminal device connected to the second network device measures the interference of the terminal device to itself according to the interference measurement signal, and sends the interference measurement result to the second network device or the first network device.

Optionally, the terminal device sends the interference measurement signal according to the first indication information, where the terminal device sends the interference measurement signal on the interference measurement resource indicated by the first indication information, where the interference measurement resource includes a time domain resource used for the interference measurement. Or one or more of the frequency domain resource or the spatial domain resource, where the interference measurement signal may be the sequence indicated in the first indication information, or may be other sequences than the sequence indicated by the first indication information.

In another implementation manner, the terminal device receives the interference measurement signal according to the first indication information, where the interference measurement signal is sent by the terminal device connected to the second network device, and the terminal device determines the interference measurement result according to the interference measurement signal, and The interference measurement result is sent to the first network device or the second network device. The interference includes interference generated by the terminal device connected by the second network device to the terminal device.

The terminal device receives the interference measurement signal according to the first indication information, where the terminal device receives the interference measurement signal sent by the other terminal device on the time domain resource, the frequency domain resource or the spatial domain resource for the interference measurement indicated by the first indication information. The interference measurement signal may be a sequence indicated in the first indication information, or may be other sequences than the sequence indicated by the first indication information. Alternatively, the terminal device receives, on the preset interference measurement resource, a sequence indicated in the first indication information, where the preset interference measurement resource is another measurement resource other than the interference measurement resource indicated by the first indication information.

After receiving the interference measurement result reported by the terminal device, the first network device and the second network device adopt a specific interference control manner for the different interference, for example, applying the same to different link directions and different link directions. Power control parameters; different overload indication (OI)/High Interference Indication (HII) interference reporting for the same link direction and different link directions; same link direction and different link direction , applying different channel measurements.

Step S103: The terminal device determines, according to the correspondence between the first indication information and the second indication information, the transmission resource information corresponding to the interference measurement.

When the first indication information includes any one or more of the time domain resource, the frequency domain resource, and the spatial domain resource used for the interference measurement, the terminal device determines the interference according to the correspondence between the first indication information and the second indication information. The corresponding transmission resource information is measured, specifically: a correspondence between the terminal device according to any one or more of a time domain resource, a frequency domain resource, and a spatial domain resource used for interference measurement, and a transmission resource used for transmitting control information, A transmission resource corresponding to the interference measurement for transmitting control information is determined. And/or, the terminal device determines, according to the correspondence between any one or more of the time domain resource, the frequency domain resource, and the spatial domain resource used for the interference measurement and the transmission resource used for transmitting the data information, A transmission resource for transmitting data information.

The terminal device selects the measurement resource from the time domain resource, the frequency domain resource, and the spatial domain resource for the interference measurement indicated by the first indication information to perform the interference measurement, and the transmission resource used for the transmission control information corresponding to the interference measurement is : a transmission resource for transmitting control information corresponding to any one or more of a time domain resource, a frequency domain resource, and a spatial domain resource used for interference measurement. The transmission resource for transmitting the data information corresponding to the interference measurement is: a transmission resource for transmitting data information corresponding to any one or more of the time domain resource, the frequency domain resource, and the spatial domain resource used for the interference measurement.

In this embodiment, the transmission resource for transmitting the control information corresponding to the interference measurement is determined according to the correspondence between the first indication information and the second indication information, and the terminal device may only be the physical downlink control channel (Physical Downlink Control Channel, PDCCH). The CCE or CORSET in which the transmission resource corresponding to the interference measurement is transmitted is detected, thereby reducing the overhead of blind detection. The PDCCH carries various control information. Taking the LTE system as an example, the terminal device generally does not know the number of CCEs occupied by the current PDCCH, and the format information of the Downlink Control Information (DCI) transmitted. I don't know where the information I need is. However, the terminal device knows what information it is currently expecting, for example, the information expected by the idle device (Idle) terminal device is paging information, and the terminal device expects a random access response message after initiating random access (Random Access). (RACH Response), expecting an uplink grant (UL Grant) when there is uplink data waiting to be transmitted. For different desired information terminal equipments, use the corresponding Radio Network Temporary Identity (RNTI) to perform Cyclic Redundancy Check (CRC) on the information carried by the CCE or CORSET. If the CRC is successful, the terminal The device knows that the information carried in the CCE or CORSET is needed by itself, and can further know the corresponding DCI format and modulation mode to solve the DCI content.

Taking CCE as an example, if the terminal device searches for the past in the order of CCE, the calculation amount of the terminal device is considerable, especially for a system with a relatively large bandwidth and a large number of CCEs. The concept of search space is defined in this protocol, and some restrictions on the possible placement of PDCCHs in different formats in the system are implemented, which reduces the complexity of blind detection by terminal devices. Each different format of PDCCH corresponds to a different search space. For example, for a PDCCH with a C number of CCEs, the CCE number of the starting position must be an integer multiple of N. Moreover, for different sizes of PDCCH, the size of the search space (defined as the number of CCEs that need to be covered by the search, that is, the product of the number of possible search positions and the number of CCEs corresponding to the PDCCH format) is not the same. Further, the LTE system also divides a Common Search Space and a UE-Specific Search Space.

In the LTE system, the number of CCEs that can be used for the PDCCH depends on the system bandwidth, the PHICH configuration, the number of antenna ports, and the PCFICH configuration. After the above factors are determined, the number of CCEs of the PDCCH can be determined, and the common search interval can be determined accordingly. The common search space usually occupies at most 16 CCEs from 0. The common search interval does not change with sub-frame changes. The terminal device-specific search interval is different. The starting point of the terminal device-specific search space depends on the terminal device ID (C-RNTI), the subframe number, and the type of the PDCCH. Therefore, the terminal device varies with the subframe. The specific search space is also different. Moreover, the terminal device-specific search space and the common search space may overlap.

In the method of this embodiment, the terminal device determines the correspondence between any one or more of the time domain resource, the frequency domain resource, and the spatial domain resource used for the interference measurement and the transmission resource used for transmitting the control information. The corresponding relationship may be used to determine a transmission resource for transmitting control information corresponding to the interference measurement, so that the terminal device detects only the CCE where the transmission resource for transmitting the control information corresponding to the interference measurement in the PDCCH is located, and does not need to be used for all CCEs. Detection is performed, thereby reducing the overhead of blind detection. The corresponding relationship can be applied to the 5G communication system. The difference is that the resource granularity of the PDCCH in the LTE system is CCE, and the resource granularity of the PDCCH in the 5G communication system is CORSET. The CORSET can include not only certain time-frequency resources but also Spatial domain resources.
