Detailed Description
So that the manner in which the features and technical contents of the embodiments of the present invention can be understood in detail, a detailed description of the embodiments of the present invention will be given below with reference to the accompanying drawings, which are provided for illustration purposes and are not intended to limit the embodiments of the present invention.
The 5G NR system simultaneously supports enhanced Mobile Broadband (eMBB) service and high-reliability Low-delay (URLLC) service; URLLC traffic is characterized by very high reliability (e.g., 99.999%) transmissions within extreme delays (e.g., 1 ms). In order to characterize URLLC services, a Preemption (Preemption) mechanism is introduced.
The Preemption mechanism is to insert URLLC service during eMBB service transmission, as shown in fig. 1. In this process, since it is not known that the URLLC service is inserted, the terminal device corresponding to the eMBB service demodulates the data of the URLLC service as the data of the eMBB service, which seriously affects the demodulation performance of the data of the eMBB service. In order to reduce the influence of the URLLC service on the eMBB service, the network device sends a Preemption indication (Preemption Indicator) to the terminal device through a downlink control signal, and the Preemption Indicator is used by the terminal device to determine which time-frequency domain resources are occupied by the URLLC service. However, the sending time of the priority Indicator lags behind the time of the priority, so that the network device cannot send the instruction of stopping uplink transmission in time; the terminal device also needs to obtain the indication of stopping uplink transmission through frequent detection signals, which increases the signaling overhead and detection complexity of the system.

As shown in fig. 3, the optional processing flow of the downlink control signal transmission method applied to the terminal device according to the embodiment of the present invention includes the following steps:
step S201, the terminal device obtains configuration information of the downlink control signal.
In some embodiments, a terminal device receives configuration information of a downlink control signal sent by a network device, where resources occupied by the downlink control signal have a corresponding relationship with transmission resources used for data transmission.
Here, the configuration information at least includes the correspondence and resource information of the downlink control signal.
The resource information of the downlink control signal includes at least one of time domain information of the downlink control signal, frequency domain information of the downlink control signal, and code domain information of the downlink control signal. It can be understood that the resource information of the downlink control signal includes: time domain information of the downlink control signal; or the resource information of the downlink control signal includes: frequency domain information of the downlink control signal; or the resource information of the downlink control signal includes: code domain information of the downlink control signal; or the resource information of the downlink control signal includes: the combination of any two of time domain information, frequency domain information and code domain information of the downlink control signal; or the resource information of the downlink control signal includes: time domain information, frequency domain information, and code domain information of the row control signal.
The corresponding relationship comprises at least one of time domain resources, frequency domain resources and code domain resources occupied by the downlink control signal and the corresponding relationship of the time domain resources and/or the frequency domain resources in the transmission resources. For example, the corresponding relationship is a corresponding relationship between at least one of a time domain resource, a frequency domain resource and a code domain resource occupied by the downlink control signal and a time domain resource in the transmission resource; or the corresponding relation is at least one of a time domain resource, a frequency domain resource and a code domain resource occupied by the downlink control signal and the corresponding relation of the frequency domain resource in the transmission resource; or the corresponding relationship is at least one of a time domain resource, a frequency domain resource and a code domain resource occupied by the downlink control signal, and the corresponding relationship between the time domain resource and the frequency domain resource in the transmission resource.
Then, taking the corresponding relationship as at least one of a time domain resource, a frequency domain resource and a code domain resource occupied by the downlink control signal, where the corresponding relationship with the time domain resource in the transmission resource is an example, optionally, the corresponding relationship is: the corresponding relation between the time domain resources occupied by the downlink control signals and the time domain resources in the transmission resources; or the corresponding relation is as follows: the corresponding relation between the time domain resource and the frequency domain resource occupied by the downlink control signal and the time domain resource in the transmission resource; or the corresponding relation is as follows: and the corresponding relation between the time domain resource, the frequency domain resource and the code domain resource occupied by the downlink control signal and the time domain resource in the transmission resource.
Optionally, when the downlink control signal is used to instruct the terminal device to stop uplink data transmission, the terminal device may detect the downlink control signal according to the configuration information, further obtain an instruction to stop uplink data transmission, and stop uplink data transmission according to the obtained instruction to stop uplink data transmission; therefore, the terminal equipment determines the resource for bearing the downlink control signal according to the configuration information, directly detects the downlink control signal on the determined resource, quickly acquires the instruction for stopping data transmission, stops the uplink data transmission in time and reduces the signaling overhead for the uplink data transmission.
Optionally, for a specific application scenario, when a downlink control signal carries a transmission stop instruction, the downlink control signal is a sequence-based control signal. However, the amount of information carried by the sequence-based control signal is limited, which is not favorable for fine indication of information; moreover, when the information quantity carried by the sequence-based control signal is increased, the terminal equipment detects that the performance of the sequence-based control signal is reduced; when the amount of information carried by the sequence-based control signal increases, the video resource overhead of the sequence-based control signal will increase in order to guarantee the capability of the terminal device to detect the sequence-based control signal. In order to solve the above problem, in the embodiments of the present invention, the amount of information indicated by the sequence-based control signal is increased through multiple dimensions of the time domain, the frequency domain, and the code domain of the downlink control signal; therefore, the indication range of the control signal based on the sequence is enlarged, the orthogonality of the control signal is ensured, and the detection performance of the terminal equipment is improved.
The following takes the downlink control signal as a sequence group, and the corresponding relationship is illustrated as follows:
1. the corresponding relation is that the downlink control signal and the time domain resource starting point for stopping data transmission have one-to-one corresponding relation; wherein, the length of stopping data transmission can be configured by semi-static state or agreed by protocol. For example, the downlink control signal sequence group includes four downlink control signal sequences, a first downlink control signal sequence corresponding to the time domain resource starting point is a first symbol, a second downlink control signal sequence corresponding to the time domain resource starting point is a third symbol, a third downlink control signal sequence corresponding to the time domain resource starting point is a fifth symbol to a seventh symbol, and a fourth downlink control signal sequence corresponding to the time domain resource starting point is a seventh symbol; and the time domain resource end point corresponding to each downlink control signal sequence is the seventh symbol through semi-static configuration or protocol convention.
2. The corresponding relation is that the downlink control signal and the time domain resource interval for stopping data transmission have one-to-one corresponding relation. For example, the downlink control signal sequence group includes four downlink control signal sequences, a time domain interval corresponding to a first downlink control signal sequence is from a first symbol to a second symbol, a time domain interval corresponding to a second downlink control signal sequence is from a third symbol to a fourth symbol, a time domain interval corresponding to a third downlink control signal sequence is from a fifth symbol to a sixth symbol, and a time domain interval corresponding to a fourth downlink control signal sequence is from a seventh symbol to an eighth symbol.
3. The corresponding relation is that the downlink control signal has a one-to-one corresponding relation with the time domain resource and the frequency domain resource for stopping data transmission. For example, the downlink control signal sequence group includes four downlink control signal sequences, a first downlink control signal sequence corresponds to first to second symbols of the first bandwidth resource, a second downlink control signal sequence corresponds to third to fourth symbols of the first bandwidth resource, a third downlink control signal sequence corresponds to first to second symbols of the second bandwidth resource, and a fourth downlink control signal sequence corresponds to third to fourth symbols of the second bandwidth resource.
In some embodiments, when the types of the correspondence include two or more types, which type of correspondence is adopted needs to be configured through higher layer signaling. For example, two corresponding relationships are defined by static configuration or by a protocol, where the first corresponding relationship is that four control signal sequences respectively correspond to a first symbol to a second symbol of a first bandwidth resource, a third symbol to a fourth symbol of the first bandwidth resource, a first symbol to a second symbol of a second bandwidth resource, and a third symbol to a fourth symbol of the second bandwidth resource; the second correspondence relationship is that four control signal sequences respectively correspond to the first symbol, the second symbol, the third symbol and the fourth symbol. At this time, the first corresponding relationship or the second corresponding relationship needs to be adopted through high-level signaling configuration. Optionally, the type of the corresponding relationship may be configured semi-statically, or may be agreed by a protocol.
In some embodiments, the configuration information of the downlink control signal is configured with a correspondence relationship between resources occupied by the downlink control signal and transmission resources used for data transmission, that is, at least one of time domain resources, frequency domain resources, and code domain resources occupied by the downlink control signal has a correspondence relationship with time domain resources and/or frequency domain resources in the transmission resources. When the downlink control signal carries an instruction to stop transmission, the terminal device can detect the downlink control signal on a resource bearing the downlink control signal corresponding to a transmission resource for transmitting data; therefore, the terminal equipment only detects the control signals on the resources corresponding to the transmission resources, and does not need to detect the control signals on all the resources, so that the signaling overhead and the detection complexity are reduced.
In some embodiments, the configuration information of the downlink control signal comprises at least one of: the method comprises the steps of allocating a bandwidth resource corresponding to a downlink control signal sequence group of the same time domain resource and frequency domain resource, allocating a frequency domain resource of the downlink control signal sequence group, allocating a time domain resource of the downlink control signal sequence group, allocating a code domain resource of the downlink control signal sequence group, allocating a corresponding relation between each downlink control signal sequence in the downlink control signal sequence group and a transmission resource, and allocating a corresponding time domain resource and a corresponding frequency domain resource of the downlink control signal sequence group of the same time domain resource. Wherein the division of transmission resources may be predefined, such as dividing only in the time domain for resources within the bandwidth corresponding to sequence set 0; the resources within the bandwidth corresponding to the sequence set1 are only divided in the frequency domain.
Optionally, the configuration information content and form of the downlink control signal are as follows:
example 2, the terminal receives the configuration information of the indication signal
Step S202, the terminal device detects a downlink control signal based on the configuration information.
In some embodiments, the terminal device determines a resource for carrying the downlink control signal according to a transmission resource corresponding to actual data transmission and the correspondence; detecting the downlink control signal on the determined resource.
For example, the corresponding relationship includes a corresponding relationship between at least one of a time domain resource, a frequency domain resource and a code domain resource occupied by the downlink control signal and a time domain resource and/or a frequency domain resource in the transmission resource; the terminal equipment searches resources occupied by downlink control signals corresponding to the transmission resources in the corresponding relation according to the transmission resources corresponding to the actually generated data transmission; and detecting the downlink control signal in the searched resource.
In the related art, as shown in fig. 4a, a group of downlink control signal sequences corresponds to all transmission resources within a bandwidth, and in order to ensure orthogonality between the downlink control signal sequences and detection performance of a terminal device, a longer downlink control signal sequence resource needs to be configured. In the embodiment of the present invention, as shown in fig. 4b, two sets of downlink control signal sequence resources respectively correspond to the upper half bandwidth resource and the lower half bandwidth resource of the available bandwidth resources, and for each set of downlink control signal sequence resources, the bandwidth resources corresponding thereto are reduced by half; therefore, the signaling overhead generated by detecting the downlink control signal is reduced, and better detection performance is realized. For example, for the network device, when the next half bandwidth resource needs to stop data transmission, the network device only sends the control signal sequence group corresponding to the next half bandwidth resource. For the terminal device, when the data transmission to be sent corresponds to the upper half bandwidth resource, the terminal device only needs to detect the downlink control signal corresponding to the upper half bandwidth resource, and does not need to detect the downlink control signal corresponding to the lower half bandwidth resource. In the embodiment of the present invention, as shown in fig. 4c, for a network device, when both an upper half bandwidth resource and a lower half bandwidth resource need to stop data transmission, a downlink control signal corresponding to the upper half bandwidth resource and a downlink control signal corresponding to the lower half bandwidth resource need to be sent.
In some embodiments, after performing step S202, the method further comprises:
step S203, the terminal device performs data processing based on the downlink control signal.
In some embodiments, when the downlink control signal is used to instruct a terminal device to stop data transmission, the terminal device stops corresponding data transmission based on the downlink control signal.
