Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

For ease of understanding, first, the concepts related to the present application will be described.

Terminal equipment: is a device with wireless receiving and transmitting function. The terminal device may be deployed on land, including indoors or outdoors, hand-held, wearable or vehicle-mounted; can also be deployed on the water surface (such as ships, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.).

The terminal device may be a mobile phone (mobile phone), a tablet (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a vehicle-mounted terminal device, a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city, a wireless terminal in smart home (smart home), a wearable terminal device, or the like.

The terminal device according to the embodiments of the present application may also be referred to as a terminal, a User Equipment (UE), an access terminal device, a vehicle terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a remote terminal device, a mobile device, a UE terminal device, a wireless communication device, a UE agent, or a UE apparatus, etc. The terminal device may also be fixed or mobile.

Network equipment: is an aerial deployed device with wireless transceiver functions. The network device may have a mobile nature, i.e. the network device may be a mobile device. Alternatively, the network device may be a satellite, a balloon station.

For example, the satellite may be a Low Earth Orbit (LEO) satellite, a medium earth orbit (medium earth orbit, MEO) satellite, a geosynchronous orbit (geostationary earth orbit, GEO) satellite, a high elliptical orbit (High Elliptical Orbit, HEO) satellite, or the like.

For example, LEO satellites typically have an orbital altitude ranging from 500km to 1500km, and an orbital period (period of rotation around the earth) ranging from about 1.5 hours to 2 hours. The signal propagation delay of the single-hop communication between users is about 20ms, and the single-hop communication delay between users refers to the transmission delay between terminal equipment and network equipment or the delay between network equipment and transmission equipment. The maximum satellite visibility time, which is the maximum time that the satellite beam covers a certain area of the ground, is about 20 minutes, and the LEO satellite is moving relative to the ground, and the area of the ground that it covers varies as the satellite moves. The LEO satellite has short signal propagation distance, less link loss and low requirement on the transmitting power of terminal equipment. The orbit height of GEO satellites is typically 35786km with an orbit period of 24 hours. The signal propagation delay for single hop communication between users is about 250ms. To ensure coverage of the satellites and to increase the system capacity of the communication network, the satellites may cover the ground with multiple beams, for example, one satellite may form tens or hundreds of beams to cover the ground, and one beam may cover a ground area with a diameter of tens to hundreds of kilometers.

PUSCH: physical Uplink Share CHannel, physical uplink shared channel.

PUCCH: physical Uplink Control CHannel, physical uplink control channel.

TDW: the time window is enhanced as a unit of time in which the terminal device desires to maintain power consistency and phase continuity between the transmission uplink channels.

Maximum duration: the maximum time for which the terminal device can maintain power consistency and phase continuity while meeting the requirements of power consistency and phase continuity.

Next, a scene to which the communication method of the present application is applied will be described with reference to fig. 1.

Fig. 1 is a schematic diagram of an application scenario provided in an embodiment of the present application. Referring to fig. 1, the wireless communication system includes a network device 12 and a terminal device 11, and wireless communication is possible between the network device 12 and the terminal device 11.

In the embodiment of the present application, the terminal device 11 includes a plurality of antenna panels, and in fig. 1, the terminal device 11 is described by taking two antenna panels as an example, which are the antenna panel 1 and the antenna panel 2 respectively.

The antenna panel may be represented by a panel, a panel index, or the like, may be represented by an antenna port or group of antenna ports, or may be represented by a resource or group of resources. There are typically one or more antennas on an antenna panel, which are arranged in an antenna array, and beamformed to form a beam. The antenna array may generate beams directed to different directions, i.e. multiple beams may be formed on each antenna panel. A better beam among the multiple beams may be selected for communication by beam measurement.

In a communication system, when a terminal device transmits uplink data to a network device, coherent transmission is generally adopted, that is, a known reference signal and unknown uplink data of the network device are transmitted simultaneously, wherein the reference signal is used for channel estimation by the network device. After channel estimation, the network device can eliminate the influence of the channel on the unknown uplink data, and then demodulate and decode the uplink data. To enhance the accuracy of channel estimation, joint channel estimation between multiple time units is currently available. That is, if the network device schedules the terminal device to transmit the uplink channel on a plurality of consecutive time units, the network device may perform joint channel estimation according to the reference signals transmitted on the plurality of time units, and then demodulate and decode the uplink data transmitted on each time unit.

The multiple time units scheduled by the network device are configured TDWs, and the configured TDWs are used for restricting the behavior of the terminal device side, so that the terminal device needs to ensure power consistency and phase continuity when transmitting the uplink channel in the time window. The event is some factors that cause the terminal device to fail to keep power consistency and phase continuity, for example, downlink data needs to be received in the configured TDW, the TDW reaches the maximum duration, and so on.

At present, the configuration of the TDW and the event is mainly aimed at a terminal device of a single antenna panel or a terminal device capable of activating only 1 antenna panel for transmitting or receiving at one moment, and no proposal is provided for how to configure the TDW and the event in a scene that multiple antenna panels can transmit or receive simultaneously. Therefore, the application provides a communication method and device, which realize the scheme that the terminal equipment sends an uplink channel according to the configuration TDW and the event of the antenna panel under the scene of the multi-antenna panel. The following will describe the scheme of the present application.

Fig. 2 is a signaling diagram of a communication method according to an embodiment of the present application, as shown in fig. 2, including:

s21, the network equipment sends TDW information to the terminal equipment, wherein the TDW information is used for indicating the configuration TDW of a plurality of antenna panels of the terminal equipment.

In the embodiment of the application, the terminal equipment is provided with a plurality of antenna panels, wherein the plurality of antenna panels represent two or more antenna panels. An antenna panel has one or more antennas arranged in an array of antennas for beam forming to form a beam. Wherein, the terminal equipment can activate more than 1 antenna panel for transmitting and receiving at one moment.

For any antenna panel, the configuration TDW of the antenna panel is a time window configured by the network device, and when the terminal device sends an uplink channel to the network device in the time window, power consistency and phase continuity need to be maintained. For a terminal device comprising a plurality of antenna panels, the network device sets corresponding configurations TDW (configured TDW) for the plurality of antenna panels by TDW information.

S22, the terminal equipment sends an uplink channel to the network equipment according to the configuration TDW and the events of the plurality of antenna panels.

Events refer to factors that cause the terminal device to fail to continue to maintain power consistency and phase continuity. When no event occurs, the terminal device will maintain power consistency and phase continuity when transmitting the uplink channel to the network device in the corresponding configuration TDW through the antenna panel. Thus, the network device may perform joint channel estimation after receiving the uplink channel. When an event occurs, the actual TDW and the configured TDW of the antenna panel of the terminal device may be different at this time, because the event may cause the terminal device to fail to maintain the power consistency and the phase continuity.

When the terminal device sends an uplink channel through the antenna panel, the uplink channel needs to be sent to the network device according to the corresponding configuration TDW and the event. The uplink channel may include PUSCH or PUCCH.

According to the communication method provided by the embodiment of the application, firstly, the network equipment sends TDW information to the terminal equipment, the TDW information is used for indicating the configuration TDWs of a plurality of antenna panels of the terminal equipment, and then the terminal equipment can send an uplink channel to the network equipment according to the configuration TDWs and events of the plurality of antenna panels. The embodiment of the application provides a scheme that terminal equipment transmits an uplink channel according to the configuration TDW and an event of an antenna panel in a multi-antenna panel scene, and realizes coherent transmission and joint channel estimation in the multi-antenna panel scene.

The following describes the scheme of the application in detail with reference to the accompanying drawings.

The network device may configure the terminal device with TDW information indicating the configuration TDW of the plurality of antenna panels of the terminal device. In one possible implementation, the TDW information is carried by radio resource control (Radio Resource Control, RRC) signaling. Specifically, the network device may send RRC signaling to the terminal device, where the RRC signaling includes TDW information. After receiving the RRC signaling, the terminal device may acquire TDW information according to the RRC signaling, so as to determine configured TDWs of the plurality of antenna panels according to the TDW information. The TDW information may include only 1 TDW, or may include N TDWs, where N is a positive integer greater than or equal to 2. The following will describe with reference to fig. 3 and 4.

Fig. 3 is a schematic diagram of a configuration TDW of a plurality of antenna panels provided in an embodiment of the present disclosure, as shown in fig. 3, a terminal device includes two antenna panels, which may simultaneously send uplink transmission or receive downlink transmission, and are respectively an antenna panel 1 and an antenna panel 2.

In the example of fig. 3, only 1 TDW is included in the TDW information, and the TDW is the first TDW, and the configuration TDWs of the antenna panel 1 and the antenna panel 2 are both the first TDW. That is, for a terminal device with multiple antenna panels, only one TDW needs to be configured by the network device, where the TDWs configured by the multiple antenna panels are the same TDW.

Fig. 4 is a second schematic diagram of a TDW configuration of multiple antenna panels provided in an embodiment of the present disclosure, as shown in fig. 4, a terminal device includes two antenna panels, which are an antenna panel 1 and an antenna panel 2 respectively.

In the example of fig. 4, the TDW information includes N TDWs, N being the number of antenna panels of the terminal device. In fig. 4, the number of antenna panels is 2, and then N is equal to 2, and 2 TDWs are included in the TDW information, which are the second TDW and the third TDW, respectively. The configuration TDWs of the N antenna panels may be determined from the N TDWs in the TDW information. For example, in fig. 4, the configuration TDW of the antenna panel 1 is the second TDW, and the configuration TDW of the antenna panel 2 is the third TDW. Namely, for the terminal device including N antenna panels, the TDW information sent by the network device includes N TDWs, and according to the N TDWs, the configuration TDW of the N antenna panels may be determined, where N is a positive integer greater than or equal to 2. The configuration TDW of any two of the N antenna panels may be the same or different.

In fig. 3 and fig. 4, the terminal device includes 2 antenna panels, and in practice, the number of antenna panels included in the terminal device may be more than 2. Taking the example that the number of antenna panels includes N, in the embodiment illustrated in fig. 3, the network device configures one TDW for the N antenna panels; in the embodiment illustrated in fig. 4, the network device may set N TDWs for the N antenna panels, where N is a positive integer greater than or equal to 2.

After determining the configuration TDW of the plurality of antenna panels, the terminal device may send an uplink channel to the network device according to the configuration TDW and the event of the plurality of antenna panels. Specifically, for any antenna panel, when no event occurs, the configured TDW of the antenna panel is the actual TDW of the antenna panel. And the terminal equipment transmits an uplink channel to the network equipment through the antenna panel in the configuration TDW. Accordingly, the network device may receive, in the configured TDW, an uplink channel transmitted by the terminal device through the antenna panel.

When an event occurs, the terminal device may determine an actual TDW of the antenna panel according to the configured TDW of the antenna panel and the event, and synchronize the actual TDW to the network device. And the terminal equipment sends the uplink channel to the network equipment according to the actual TDW, and correspondingly, the network equipment receives the uplink channel according to the actual TDW of the antenna panel.

Fig. 5 is a schematic diagram of a configured TDW and an actual TDW provided in an embodiment of the present application, as shown in fig. 5, for any one first antenna panel of a plurality of antenna panels of a terminal device, a TDW configured by a network device for the first antenna panel is TDW1 in fig. 5, and a time window corresponding to TDW1 is a time period from t0 to t 2.

When the terminal device sends an uplink channel to the network device through the first antenna panel, if no event occurs, the TDW configured by the network device for the first antenna panel is not affected, and the terminal device needs to maintain power consistency and phase continuity when sending the uplink channel in the TDW1 through the first antenna panel.

When the terminal device sends an uplink channel to the network device through the first antenna panel, if an event occurs, the TDW configured by the network device for the first antenna panel may be affected, where the event has multiple types. For example, in fig. 5, at time t1 the terminal device needs to receive downstream data through the first antenna panel, which is considered an event, the power consistency and phase continuity of the terminal device in TDW1 through the first antenna panel are affected. At this time, the actual TDWs of the first antenna panel, i.e., TDW2 and TDW3 in fig. 5, are determined according to TDW1 and the event. The time window corresponding to the TDW2 is a time period from t0 to t1, and the time window corresponding to the TDW3 is a time period from t1 to t 2.

In fig. 5, TDW2 and TDW3 are based on TDW1, and the time window before and after occurrence of an event is divided into two TDWs due to occurrence of the event. In TDW2, the terminal device needs to ensure power consistency and phase continuity when transmitting the uplink channel through the first antenna panel, and in TDW3, the terminal device needs to ensure power consistency and phase continuity when transmitting the uplink channel through the first antenna panel.

Therefore, when no event occurs, the actual TDW of the antenna panel is the configured TDW, and when an event occurs, the actual TDW needs to be determined according to the configured TDW and the event.

In the embodiment of the application, for the terminal equipment of the multi-antenna panel, the event can also comprise antenna panel switching. The antenna panel switching may include, for example, the terminal device switching the first antenna panel to the second antenna panel. For example, switching the TRP corresponding to the first antenna panel from the first TRP to the second TRP corresponding to the second antenna panel may be included. Wherein the first TRP and the second TRP may be the same TRP or different TRPs. The process will be described with reference to the accompanying drawings.

Fig. 6 is a schematic diagram of antenna panel switching provided in an embodiment of the present application, as shown in fig. 6, a terminal device includes an antenna panel 1 and an antenna panel 2, and an initial terminal device communicates with a first TRP through the antenna panel 1, where a beam thereof is shown in the left side in fig. 6. The configuration TDW of the antenna panel 1 and the antenna panel 2 is the same.

At some point in time, the antenna panel is switched, after which the terminal device communicates with the second TRP via the antenna panel 2, the beam of which is shown to the right in fig. 6. Since the terminal device switches the first antenna panel to the second antenna panel, an event is considered to have occurred at this time. Wherein the event may act on both antenna panels or only one of the two antenna panels, e.g. the first antenna panel or the second antenna panel. The terminal device needs to re-determine the actual TDW according to the configured TDW and then transmit the uplink channel to the second TRP according to the actual TDW and the antenna panel 2.

Fig. 7 is a second schematic diagram of antenna panel switching provided in an embodiment of the present application, as shown in fig. 7, where a terminal device includes an antenna panel 1 and an antenna panel 2, and an initial terminal device communicates with a first TRP through the antenna panel 1, and a beam thereof is shown in the left side in fig. 7. The configuration TDW of the antenna panel 1 and the antenna panel 2 is the same.

At some point in time, the antenna panel is switched, after which the terminal device communicates with the second TRP through the antenna panel 2 and the terminal device communicates with the first TRP through the antenna panel 1, the beam of which is shown to the right in fig. 7.

In one possible implementation, for the antenna panel 1, it is considered that an event occurs at this time, which may cause the power uniformity and phase continuity of the antenna panel 1 to be affected.

In one possible implementation, for the antenna panel 1, since the antenna panel 1 is in communication with the first TRP before and after the switching, the beam thereof is not switched, and the antenna panel 1 is considered to be not incident, and there is no influence on the power uniformity and phase continuity of the antenna panel 1.

For the antenna panel 2, it has an event that an actual TDW needs to be re-determined according to the configured TDW, and then an uplink channel is transmitted to the second TRP according to the actual TDW and the antenna panel 2.

It should be noted that, in fig. 7, a scenario in which 1 antenna panel is switched to 2 antenna panels is illustrated, and the discussion on the event in fig. 7 may also be applicable to a scenario in which 2 antenna panels are switched to 1 antenna panel.

For example, if the initial terminal device communicates with the first TRP through the antenna panel 1, communicates with the second TRP through the antenna panel 2. At some point, a handover occurs to the antenna panel, after which the terminal device communicates with the second TRP only through the antenna panel 2.

In this scenario, it is considered that an event has occurred with respect to the antenna panel 1, which affects the power uniformity and phase continuity of the antenna panel 1 within the configuration TDW.

In one possible implementation, this switching of the antenna panel is also considered to occur for the antenna panel 2, affecting the power consistency and phase continuity of the antenna panel 2 within the configuration TDW.

In one possible implementation, for the antenna panel 2, since both before and after switching the antenna panel 2 is in communication with the second TRP, its beam is not switched, and it is considered that the antenna panel 2 is not incident, there is no effect on the power uniformity and phase continuity of the antenna panel 2.

In fig. 6 and fig. 7, taking an example that a terminal device includes two antenna panels that can transmit uplink transmission or receive downlink transmission simultaneously, it is described whether an event affecting power uniformity and phase continuity occurs for each antenna panel in the case of switching of different types of antenna panels. When the terminal device includes more than two antenna panels capable of simultaneously transmitting uplink transmission or receiving downlink transmission, it may be determined whether an event occurs for each antenna panel based on the description of the embodiments of fig. 6 and fig. 7, which will not be repeated here.

After the terminal device determines the actual TDW of each antenna panel according to the configuration TDW of each antenna panel and the event, the terminal device may synchronize the actual TDW of each antenna panel to the network device, and after the network device receives the actual TDW of each antenna panel, the network device may receive the uplink channel from the terminal device according to the actual TDW of each antenna panel. For any one antenna panel, since the terminal device maintains power consistency and phase continuity when transmitting an uplink channel to the network device in the actual TDW of the antenna panel, the network device can perform joint channel estimation for the uplink channel received in the actual TDW after receiving the uplink channel.

According to the communication method provided by the embodiment of the application, firstly, the network equipment sends TDW information to the terminal equipment, the TDW information is used for indicating the configuration TDWs of a plurality of antenna panels of the terminal equipment, and then the terminal equipment can send an uplink channel to the network equipment according to the configuration TDWs and events of the plurality of antenna panels. The configuration TDW of the plurality of antenna panels of the terminal device may be the same TDW, or may be different TDWs of the antenna panels, which provides a scheme that the terminal device sends an uplink channel according to the configuration TDW and an event of the antenna panels in a multi-antenna panel scene, thereby implementing coherent transmission and joint channel estimation in the multi-antenna panel scene.
