[0036] Some embodiments of the present disclosure will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Various changes, variations, and equivalents of the methods, apparatuses, and / or systems described herein will become apparent after understanding the present disclosure. For example, the order of operations described herein is merely an example and is not limited to those set forth herein, but may be changed as will be apparent after understanding the present disclosure, except for operations that must be performed in a specific order. Additionally, descriptions of features known in the art may be omitted for the sake of clarity and conciseness. It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other.

[0037] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] Figure 1 is a flowchart of a communication method shown according to some embodiments of the present disclosure, as Figure 1 shown, and includes the following steps.

[0039] Step 101, obtain a first configuration and a second configuration.

[0040] The execution subject of this embodiment may be a communication device or a communication equipment, such as an electronic device or a chip, etc., and may be configured on the terminal side such as a terminal device.

[0041] In some examples, the terminal device may be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may also be an automobile with communication capabilities, a smart vehicle, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver capabilities, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, and so on. This embodiment does not limit the specific technologies and specific device forms adopted by the terminal device.

[0042] In some embodiments, the terminal device may determine, by parsing DCI, that it needs to receive the first information sent by the network device. The first information may be a specific downlink signal configured by the network layer to meet corresponding service requirements.

[0043] For example, the terminal device may monitor the Physical Downlink Control Channel (PDCCH). For instance, the terminal device monitors the PDCCH on the designated symbols of each slot or Mini-Slot to find the control information allocated to itself. The PDCCH carries scheduling information and other control instructions. When the terminal device identifies a PDCCH that may be allocated to itself, it attempts to decode the DCI. The DCI contains a lot of information, such as the resource allocation type (e.g., the time-frequency resources of the PDSCH), the modulation and coding scheme (MCS), the transport block size (TB Size), the Hybrid Automatic Repeat-reQuest (HARQ) related information, and the indication of whether CSI-RS is included, etc. If the DCI contains the configuration indication of the first information, it means that the terminal device needs to receive the first information configured by the network layer, that is, it means that the terminal device needs to receive the first information sent by the network device.

[0044] In some examples, the network device may be a device such as a base station or a satellite. In this embodiment, no specific limitation is made. The network device may be an entity on the network side for transmitting or receiving signals. For example, the network device may be a communication satellite, an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system, etc. The embodiments of the present disclosure do not limit the specific technologies and specific device forms adopted by the network device. The network device provided in this embodiment may be composed of a central unit (CU) and a distributed unit (DU). Among them, the CU may also be referred to as a control unit. Adopting the CU-DU structure can split the protocol layer of the network device, such as a base station. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0045] When it is determined that the first information that needs to receive the network high-layer configuration is required, the first configuration and the second configuration may be obtained. The first configuration is used to determine the time unit configuration of the common uplink and downlink in the TDD mode; the second configuration is used to determine the time unit configuration of the dedicated uplink and downlink in the TDD mode.

[0046] The first configuration may correspond to the setting of the tdd-UL-DL-ConfigurationCommon parameter in the protocol. This parameter can be used to indicate the general uplink (UL, Uplink) and downlink (DL, Downlink) time unit configurations in the TDD mode. It can be applied to the configuration of the entire cell range, which is common to all terminal devices and affects the time slot structure of the entire cell and the allocation method of uplink and downlink resources.

[0047] The second configuration may correspond to the setting of the tdd-UL-DL-ConfigurationDedicated parameter in the protocol. This parameter is to meet the personalized needs of specific users or services. Different from the general configuration at the cell level (i.e., the above first configuration), tdd-UL-DL-ConfigurationDedicated is customized for a single terminal device, providing more flexible resource management and optimization means.

[0048] In some examples, the time unit may be a frame, a subframe, a time slot (Slot), a symbol, a resource block (Resource Block, RB), etc.

[0049] In some embodiments, after obtaining the first configuration and the second configuration, it is possible to determine whether a preset condition is satisfied according to the first configuration and the second configuration.

[0050] Step 102: When it is determined according to the first configuration and the second configuration that the preset condition is satisfied, receive the first information sent by the network device.

[0051] The content of the preset condition can be pre-configured according to actual needs. For example, the preset condition can be a condition for being able to receive the first information configured by the network higher layer. When it is determined according to the first configuration and the second configuration that the preset condition is satisfied, the terminal device can receive the first information sent by the network device, which can ensure the downlink reception traffic.

[0052] For another example, the preset condition can be some specific conditions. In the related art, if it is determined according to the first configuration and the second configuration that the specific condition is satisfied, the terminal device is not allowed to receive the first information sent by the network device. However, in this embodiment, when it is determined according to the first configuration and the second configuration that the specific condition is satisfied, if the terminal device needs to receive the first information configured by the network higher layer, the terminal device can receive the first information sent by the network device, which can ensure the downlink reception traffic of the terminal device, ensure that there is no downlink error code on the terminal device side, and ensure the downlink performance of the terminal device side.

[0053] For further illustration of the specific implementation process of the method as Figure 1 shown, taking the first information including PDSCH and / or CSI-RS as an example, this embodiment provides a specific method as Figure 2 shown, and the method includes:

[0054] Step 201: Obtain the first configuration and the second configuration.

[0055] In some embodiments, the first configuration can be used to determine the time unit configuration of the common uplink and downlink in the TDD mode. For example, the first configuration can correspond to the setting of the tdd-UL-DL-ConfigurationCommon parameter in the protocol.

[0056] In some embodiments, the second configuration can be used to determine the time unit configuration of the dedicated uplink and downlink in the TDD mode. For example, the second configuration can correspond to the setting of the tdd-UL-DL-ConfigurationDedicated parameter in the protocol.

[0057] For this embodiment, the terminal device can determine that it needs to receive PDSCH and / or CSI-RS sent by the network device by parsing the DCI.

[0058] For example, the terminal device can monitor the PDCCH. For example, the terminal device monitors the PDCCH on the designated symbols of each time slot (Slot) or Mini-Slot to find the control information assigned to itself. The PDCCH carries scheduling information and other control instructions, such as the resource allocation of the PDSCH and CSI-RS. When the terminal device identifies a PDCCH that may be assigned to itself, it attempts to decode the DCI. If the DCI indicates an allocation of a PDSCH, it means that the terminal device needs to receive the PDSCH configured by the network layer. The terminal device can receive the PDSCH data on the designated time-frequency resources according to the resource allocation information in the DCI. In addition, the terminal device also needs to demodulate and decode the received data according to the MCS and TB Size information in the DCI. If the DCI contains a configuration indication of the CSI-RS, the terminal device will be notified of when and where to receive the CSI-RS. The CSI-RS is used for channel quality measurement, and then helps the terminal device generate and report the channel state information (Channel State Information, CSI) to the network, such as the channel quality indicator (Channel Quality Indicator, CQI), precoding matrix indicator (Precoding Matrix Indicator, PMI), rank indicator (Rank Indicator, RI), etc. The configuration of the CSI-RS is usually provided by the network side during the establishment or reconfiguration of the radio resource control (Radio Resource Control, RRC) connection, and can be temporarily adjusted through the DCI. For this embodiment, the terminal device participates in the downlink data transmission and the measurement and reporting of the channel state by continuously monitoring the PDCCH and correctly decoding the DCI, so as to know when and where to receive the PDSCH data and the CSI-RS signal.

[0059] Step 202: Determine whether a preset condition is satisfied according to the first configuration and the second configuration.

[0060] Step 203: When it is determined that the preset condition is satisfied according to the first configuration and the second configuration, receive the PDSCH and / or CSI-RS sent by the network device.

[0061] In some embodiments, satisfying the preset condition includes one of the following (A1 to B1). In some examples, when the condition of A1 is satisfied or the condition of B1 is satisfied, if the terminal device needs to receive the PDSCH and / or CSI-RS configured by the network layer, the terminal device can receive the PDSCH and / or CSI-RS sent by the network device, which can ensure the downlink reception traffic, ensure that there is no downlink error code on the terminal device side, and ensure the downlink performance of the terminal device side.

[0062] A1. The first configuration as a flexible time unit, and / or the second configuration as a flexible time unit.

[0063] The flexible time unit can be used for both uplink transmission and downlink reception. For example, as Figure 3 shown, for a time slot (slot N) containing 14 symbols (symbols, abbreviated as symb), the flexible symbol (flexible symb) is selected and configured flexibly as needed, and it can be used for the uplink transmission or downlink reception of the terminal device.

[0064] For example, according to the protocol regulations as follows:

[0065] When the tdd-UL-DL-ConfigurationCommon parameter and / or the tdd-UL-DL-ConfigurationDedicated parameter is configured as flexiblesymb, the terminal device side cannot receive the PDSCH and / or CSI-RS configured by the higher layer.

[0066] For the technical solution proposed in the embodiments of the present disclosure, when the tdd-UL-DL-ConfigurationCommon parameter and / or the tdd-UL-DL-ConfigurationDedicated parameter is configured as flexiblesymb, it can be determined that the preset conditions are met. If the terminal device needs to receive the PDSCH and / or CSI-RS configured by the higher layer, the terminal device can be allowed to receive the PDSCH and / or CSI-RS, which can ensure the downlink reception traffic, ensure that there is no downlink error code on the terminal device side, and ensure the downlink performance of the terminal device side.

[0067] B1. Neither the first configuration nor the second configuration is configured, and no DCI of a preset type is detected. In some examples, the DCI of the preset type can be DCI of format 2_0, or DCI of other format types, etc.

[0068] For example, according to the protocol regulations as follows:

[0069] When the tdd-UL-DL-ConfigurationCommon parameter and the tdd-UL-DL-ConfigurationDedicated parameter are not configured, and the terminal device does not detect DCI of format 2_0, the terminal device side cannot receive the PDSCH and / or CSI-RS configured by the higher layer.

[0070] For the technical solution proposed in the embodiments of the present disclosure, when the tdd-UL-DL-ConfigurationCommon parameter and the tdd-UL-DL-ConfigurationDedicated parameter are not configured, and the terminal device does not detect DCI in the 2_0 format, it can be determined that the preset conditions are met. If the terminal device needs to receive the PDSCH and / or CSI-RS configured by the higher layer, the terminal device can be allowed to receive the PDSCH and / or CSI-RS, which can ensure the downlink reception traffic, ensure that there is no downlink error code on the terminal device side, and ensure the downlink performance of the terminal device side.

[0071] In some embodiments, meeting the preset conditions may further include at least one of the following (A2 to B2):

[0072] A2. There is no radio frequency antenna conflict. B2. The radio frequency resources are sufficient.

[0073] When tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated is configured as flexiblesymb; or when tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated are not configured, and the terminal device does not detect DCI in the 2_0 format, as long as there is no radio frequency antenna conflict and there are sufficient radio frequency resources, the terminal device side can receive the PDSCH and / or CSI-RS signals configured by the higher layer.

[0074] In some embodiments, receiving the first information sent by the network device may specifically include: receiving the first information sent by the network device through a flexible time unit, that is, receiving the PDSCH and / or CSI-RS sent by the network device through a flexible time unit. For example, on the terminal device side in flexiblesymb, the PDSCH and / or CSI-RS signals configured by the higher layer can be received

[0075] For example, such as Figure 4As shown, when it is determined by parsing the DCI that it is necessary to receive the PDSCH and / or CSI-RS configured by the network higher layer, when tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated are configured as flexible symbols; or when tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated are not configured and the terminal device does not detect the DCI of format 2_0, as long as there is no radio frequency antenna conflict and there are sufficient radio frequency resources, the terminal device side can receive the PDSCH and / or CSI-RS signals configured by the higher layer in the flexible symbols. Furthermore, regardless of whether the conditions specified by the protocol are met, by applying the solution of this embodiment, the terminal device can receive the PDSCH and / or CSI-RS signals configured by the network higher layer, thereby ensuring the downlink reception traffic, ensuring that there is no downlink error code on the terminal device side and ensuring the downlink performance of the terminal device side.

[0076] Figure 5 is a block diagram of a communication device shown according to some embodiments of the present disclosure. Referring to Figure 5 the device includes: an acquisition module 31 and a reception module 32.

[0077] The acquisition module 31 is configured to acquire a first configuration and a second configuration, where the first configuration is used to determine the time unit configuration of the common uplink and downlink in the TDD mode, and the second configuration is used to determine the time unit configuration of the dedicated uplink and downlink in the TDD mode;

[0078] The reception module 32 is configured to receive the first information sent by the network device when it is determined according to the first configuration and the second configuration that a preset condition is met.

[0079] In some embodiments, the first information includes at least one of the following:

[0080] PDSCH; CSI-RS.

[0081] In some embodiments, meeting the preset condition includes one of the following:

[0082] The first configuration is a configuration of flexible time units, and / or the second configuration is a configuration of flexible time units;

[0083] Neither the first configuration nor the second configuration is configured, and a DCI of a preset type is not detected.

[0084] In some embodiments, the preset type of DCI is the DCI of format 2_0.

[0086] There is no radio frequency antenna conflict; the radio frequency resources are sufficient.
