Technical Field

The present invention relates to the field of communications technologies, and in particular, to a transmission method, a detection method, a network device, and a terminal.

Background

In a New Radio (NR), a User Equipment (User Equipment, UE) can only perform Physical Downlink Control Channel (PDCCH) detection according to a detection position configured by a high-level signaling, and even if a terminal configures Discontinuous Reception (DRX), due to uncertainty of a time of a data packet, a situation that the PDCCH is detected by the UE in a null state but is not scheduled still occurs in some DRX periods. In this case, the UE performs useless PDCCH detection, consuming energy. To solve this problem, a power saving signal is introduced. One of the roles of the power saving signal is to indicate whether the terminal detects the PDCCH at the associated DRX cycle. If the terminal detects the energy-saving signal or the energy-saving signal indicates that the terminal detects the PDCCH in the corresponding DRX period, otherwise, the terminal does not detect the PDCCH in the corresponding DRX period.

At present, no specific specification exists for how to flexibly send the energy-saving signal to wake up the terminal by the network device.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For the energy-saving signal, it can be designed as a physical downlink control channel PDCCH of a UE-specific search space or a PDCCH of a common search space, but both methods have their own advantages and disadvantages.

Under the condition that the energy-saving signal is the PDCCH of the UE-specific search space, the UE-specific energy-saving signal may be sent discontinuously, that is, when a certain UE needs to be woken up, the network side (which may be understood as network equipment) needs to send the energy-saving signal, and when the UE does not need to be woken up, the network side does not need to send the energy-saving signal. The terminal can detect the energy-saving signal by adopting a simple energy detection mode, and the UE detects that the energy-saving signal is awakened. The energy-saving signal is only dedicated to one UE, and the energy-saving signal can carry scheduling information and carries out data scheduling while triggering the terminal to wake up. When the number of terminals to be simultaneously awakened is large, the network side needs to occupy a large amount of signaling overhead, and transmits a dedicated energy-saving signal for each terminal.

Under the condition that the energy-saving signal is the PDCCH of the common search space, when the number of terminals needing to be awakened at the same time is large, a plurality of UEs detect one energy-saving signal together, and the network side overhead can be saved. Because the energy-saving signal indicates that each UE wakes up in a bitmap (bitmap) manner, the terminal can determine whether it needs to wake up by analyzing an information field therein after detecting the energy-saving signal. Therefore, the terminal must perform PDCCH detection and decoding at each detection opportunity, and even if the terminal does not need to wake up, certain energy consumption for detecting and decoding the energy-saving signal is wasted.

The PDCCH of the UE dedicated search space can be detected only by one terminal, and is mainly used for scheduling a Physical Downlink Shared Channel (PDSCH) or a Physical Uplink Shared Channel (PUSCH). The PDCCH of the common search space may be detected by multiple terminals, and is mainly used for transmitting scheduling information such as system messages, paging, random access response, and the like, as well as frame structure indication, power control information, and the like.

Referring to fig. 1, fig. 1 is a flowchart of a transmission method provided in an embodiment of the present invention, and is applied to a network device, as shown in fig. 1, the method includes the following steps:

step 101, configuring at least two DCI formats for a terminal, where the at least two DCI formats are used to indicate whether the terminal performs PDCCH detection in an associated DRX cycle.

Specifically, the network device includes at least two Downlink Control Information (DCI) formats, where the at least two DCI formats are used to indicate whether the terminal performs PDCCH detection in an associated DRX cycle.

Further, the at least two DCI formats include a first DCI format and a second DCI format; the first DCI format is used for indicating whether a single terminal performs PDCCH detection in an associated DRX period; the second DCI format is used to indicate whether at least two terminals perform PDCCH detection in an associated DRX cycle.

That is, of the at least two DCI formats, there is a first DCI format used to indicate whether a terminal performs PDCCH detection in an associated DRX cycle, where Cyclic Redundancy Check (CRC) of the PDCCH is scrambled by a Cell-radio network temporary identifier (C-RNTI), and the DCI format carries PDSCH time domain resource allocation and frequency domain resource allocation information, or carries time domain resource allocation and frequency domain resource allocation information of a PUSCH.

In the at least two DCI formats, a second DCI format exists for indicating whether a group of terminals (i.e., at least two terminals) performs PDCCH detection in an associated DRX cycle, where CRC of the PDCCH is scrambled by a group Radio Network Temporary Identity (RNTI), and the DCI format indicates which terminals need to perform PDCCH detection in the associated DRX cycle through a bitmap (bitmap).

Step 102, selecting a DCI format from at least two DCI formats.

And 103, sending the PDCCH carrying the selected DCI format.

And after determining the sent DCI format, the network equipment sends the PDCCH carrying the selected DCI format.

In the specific embodiment of the present invention, the network device selects one DCI format from at least two DCI formats, and transmits the DCI format carried in the PDCCH. That is, the network device can only transmit a PDCCH of one DCI format for one terminal at the same time or in the same detection time slot.

In the related art, generally, one DCI format is defined for one event, that is, different DCI formats serve different events that have been predefined, for example, DCI0 is used for PUSCH scheduling, DCI1 is used for scheduling PDSCH single code word, …, and thus the network side does not have the characteristic of flexibly selecting a DCI format. In the embodiment of the present invention, for the network side, at least two DCI formats are set for the terminal for the same event (wake-up terminal), so that when the terminal needs to be woken up, one DCI format may be selected according to different scenarios (for example, the number of terminals that need to be woken up), different parameters, or other policies, and the selected DCI format is sent to wake up the terminal, thereby improving the flexibility of sending the energy saving signal.

In this embodiment, the network device configures at least two DCI formats for the terminal, selects one DCI format from the at least two DCI formats, where the at least two DCI formats are used to indicate whether the terminal performs PDCCH detection in an associated DRX cycle, and sends a PDCCH carrying the selected DCI format. Because the network device includes at least two DCI formats, when the network device wakes up the terminal, the network device can select the transmitted DCI format according to the actual situation (for example, according to the number of terminals to be woken up), flexibly adjust the signaling overhead of the network device and the complexity of the terminal detection energy-saving signal (the energy-saving signal can be understood as PDCCH carrying the DCI format), not only can optimize the signaling overhead of the network device, but also can reduce the false wake-up probability of the terminal and the complexity of the terminal detection energy-saving signal, and achieve the balance between the network device overhead and the terminal energy-saving effect.

For example, when the number of terminals that need to be woken up is small, the network device sends the PDCCH carrying the first DCI format, which can reduce the complexity of the terminal detecting the power saving signal (i.e., the PDCCH carrying the selected DCI format); under the condition that the number of terminals needing to be awakened is large, the network equipment sends the PDCCH carrying the second DCI format, and the signaling overhead of the network equipment can be reduced.

Further, selecting one DCI format from the at least two DCI formats specifically includes:

and selecting one DCI format from at least two DCI formats according to the information of the number of the terminals needing to be awakened.

The network device may flexibly select the DCI format to be transmitted according to the number of terminals that need to be woken up, for example, when the number of terminals that need to be woken up is less than a preset value, or the number of terminals that need to be woken up is less than a preset ratio (the number of terminals that need to be woken up is greater than the ratio of the number of terminals that need to be woken up to the total number of terminals connected to the network device, and the preset ratio may be 30%, which is not limited herein), the first DCI format is selected to be transmitted, so that the complexity of a terminal detecting an energy saving signal (i.e., a PDCCH carrying the first DCI format) may be reduced (for example, the terminal may perform PDCCH detection in a simple energy detection manner), and the terminal detects. Meanwhile, the PDCCH is only dedicated to one terminal, and the PDCCH can also carry scheduling information, so that data scheduling is carried out while the terminal is triggered to wake up. When the number of the terminals needing to be awakened is not less than a preset value or the ratio of the number of the terminals needing to be awakened is not less than a preset ratio, the second DCI format is selected to be sent, and at the moment, a plurality of terminals detect one PDCCH together, so that the overhead of network equipment can be saved.

Different DCI formats of the at least two DCI formats are configured to detect in respective different search spaces; alternatively, different DCI formats are configured to be detected in the same search space.

Specifically, the network device configures a plurality of search spaces, for example, a dedicated search space and a common search space, for the terminal. Different DCI formats are configured to be detected in respective different search spaces. For example, a first DCI format is configured to be detected in a terminal-specific search space and a second DCI format is configured to be detected in a common search space. The detection periods of the plurality of search spaces are the same.

The network device configures a search space for the terminal, and can detect two DCI formats in the search space, where a first DCI format is used to indicate whether a terminal performs PDCCH detection in an associated DRX cycle, where a CRC of the PDCCH is scrambled by a C-RNTI, and the DCI format carries PDSCH time domain resource allocation and frequency domain resource allocation information or carries PUSCH time domain resource allocation and frequency domain resource allocation information, for example, the first DCI format includes a first information domain and a second information domain, where the first information domain is used to indicate time domain resource allocation of a PDSCH or a PUSCH scheduled by the terminal; the second information field is used for indicating the frequency domain resource allocation of the PDSCH or PUSCH scheduled by the terminal.

In order to reduce the complexity of terminal implementation, the search space is limited, and in the specific embodiment of the present invention, one way is to configure the at least two DCI formats to be detected in the same search space, so that the search space can be saved and the utilization rate of resources is improved.

The second DCI format is used to indicate whether a group of terminals (i.e., at least two terminals) performs PDCCH detection in an associated DRX cycle, where CRC of the PDCCH is scrambled by a group Radio Network Temporary Identity (RNTI), and the DCI format indicates which terminals need to perform PDCCH detection in the associated DRX cycle through bitmap.

Referring to fig. 2, fig. 2 is a flowchart of a detection method provided in an embodiment of the present invention, and is applied to a terminal, as shown in fig. 2, the method includes the following steps:

step 201, selecting one DCI format from at least two DCI formats configured for a terminal by a network device to perform PDCCH detection; the at least two DCI formats are used for indicating whether the terminal performs PDCCH detection in the associated DRX period.

The network equipment configures at least two DCI formats for the terminal, wherein the at least two DCI formats are used for indicating whether the terminal carries out PDCCH detection in the associated DRX period.

In the at least two DCI formats, a second DCI format exists for indicating whether a group of terminals (i.e., at least two terminals) performs PDCCH detection in an associated DRX cycle, where CRC of the PDCCH is scrambled by a group Radio Network Temporary Identity (RNTI), and the DCI format indicates which terminals need to perform PDCCH detection in the associated DRX cycle through bitmap.

Step 202, when the PDCCH is detected, stopping detecting PDCCHs of other DCI formats.

If the terminal detects the power-saving signal of one DCI format (the power-saving signal can be understood as the PDCCH carrying the DCI format), it does not need to detect another power-saving signal of another DCI format.

In the related art, once the network device configures multiple DCI formats for the terminal, the terminal needs to detect each DCI format because different DCI formats serve different predefined events.

In the specific embodiment of the present invention, for a certain terminal, at least two DCI formats have the same purpose, and are both used to indicate whether the terminal performs PDCCH detection in the associated DRX cycle, so that after the terminal detects the energy-saving signal of one DCI format, it is not necessary to detect the energy-saving signal of another DCI format, thereby reducing the power consumption of the terminal.

If the terminal detects the energy-saving signal of the first DCI format, the terminal needs to perform PDCCH detection in the associated DRX cycle, and may receive the PDSCH according to the time domain resource allocation and frequency domain resource allocation information of the PDSCH carried in the first DCI format, or transmit the PUSCH according to the time domain resource allocation and frequency domain resource allocation information of the PUSCH carried in the first DCI format.

And if the terminal detects the energy-saving signal of the second DCI format, the terminal needs to decode the DCI format and judges whether the terminal carries out PDCCH detection in the associated DRX period or not through bitmap (bitmap) indication in the second DCI format.

In this embodiment, one DCI format is selected from at least two DCI formats configured for a terminal by a network device to perform PDCCH detection; the at least two DCI formats are used for indicating whether the terminal carries out PDCCH detection in the associated DRX period; and under the condition that the PDCCH is detected, the PDCCH of other DCI formats is stopped to be detected, so that the power consumption of the terminal is reduced.

Further, different DCI formats are configured to be detected in respective different search spaces; the specific step of selecting one DCI format from at least two DCI formats configured for the terminal by the network device to perform PDCCH detection is:

and selecting one search space from different search spaces configured for the at least two DCI formats for PDCCH detection.

Specifically, the network device configures a plurality of search spaces, for example, a dedicated search space and a common search space, for the terminal. Different DCI formats are configured to be detected in respective different search spaces. For example, a first DCI format is configured to detect in a terminal-specific search space and a second DCI format is configured to detect PDCCH in a common search space. The terminal may select one search space from different search spaces configured for the at least two DCI formats to perform PDCCH detection, for example, may perform PDCCH detection from an exclusive search space, that is, detect a PDCCH carrying a first DCI format, or perform PDCCH detection from a common search space, that is, detect a PDCCH carrying a second DCI format. And if the terminal detects the energy-saving signal in the exclusive search space, stopping detecting the energy-saving signal in the public search space, or if the terminal detects the energy-saving signal in the public search space, stopping detecting the energy-saving signal in the exclusive search space.

The terminal can preferentially select the exclusive search space to detect the PDCCH, so that the false awakening probability of the terminal and the complexity of the terminal for detecting the energy-saving signal are reduced.

Further, the at least two DCI formats are configured to be detected in the same search space; the specific step of selecting one DCI format from at least two DCI formats configured for the terminal by the network device to perform PDCCH detection is: and in the search space, selecting one DCI format from at least two DCI formats to perform PDCCH detection.

The network equipment configures a search space for the terminal, and the terminal can perform PDCCH detection on two DCI formats in the search space, wherein the first DCI format is used for indicating whether the terminal performs PDCCH detection in an associated DRX period, the CRC of the PDCCH is scrambled by C-RNTI, and the DCI format carries PDSCH time domain resource allocation and frequency domain resource allocation information or carries PUSCH time domain resource allocation and frequency domain resource allocation information. The second DCI format is used to indicate whether a group of terminals (i.e., at least two terminals) performs PDCCH detection in an associated DRX cycle, where CRC of the PDCCH is scrambled by a group Radio Network Temporary Identity (RNTI), and the DCI format indicates which terminals need to perform PDCCH detection in the associated DRX cycle through bitmap.

In the embodiment of the present invention, the at least two DCI formats are configured to be detected in the same search space, so that the search space can be saved, and the resource utilization rate is improved. For the terminal, detection of different DCI formats is only required in one search space, which reduces complexity of terminal implementation and detection power consumption of the terminal.

For example, there are a first format PDCCH and a second format PDCCH in the dedicated search space, or a first format PDCCH and a second format PDCCH in the common search space. The terminal can select one DCI format in the exclusive search space for PDCCH detection, or select one DCI format in the common search space for PDCCH detection. When the network equipment wakes up the terminal, the terminal can select one DCI format from at least two DCI formats configured for the terminal by the network equipment to detect the PDCCH, so that the false wake-up probability of the terminal and the complexity of detecting the energy-saving signal by the terminal can be reduced.
