Description

Communication method and device

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a communication method and apparatus.

Background

A New Radio (NR) system of the fifth generation mobile communication technology (5th generation, 5G) can adopt a method of adding an intermediate node to improve the performance of a terminal device at the edge of a cell, such as uplink capacity and transmission reliability, and such an intermediate node is generally called a relay (relay). Because the transmission power of the network device is often greater than that of the terminal device, and the downlink transmission performance from the network device to the terminal device is usually better than the uplink transmission performance from the terminal device to the network device, the relay mainly acts to improve the uplink performance of the terminal device located at the edge of the cell.

There are two schemes for activating and deactivating relays in the prior art. One solution is to keep the relays always on, but an always on relay will always amplify the signal noise and reduce the signal to noise ratio, resulting in reduced cell capacity. Another solution is that the network device controls the activation and deactivation of the relay. Because the network device is difficult to obtain the accurate position information of the terminal device, the network device cannot accurately open the periphery of the terminal device, and can effectively amplify the relay of the signal of the terminal device, thereby failing to effectively improve the uplink performance of the terminal device.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: global system for mobile communications (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, General Packet Radio Service (GPRS), Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD), universal mobile telecommunications system (universal mobile telecommunications system, UMTS), Worldwide Interoperability for Microwave Access (WIMAX) communication systems, fifth generation (5G) or new NR systems, etc., or other similar communication systems applied to future communications.

Please refer to fig. 1, which is a schematic diagram of a network architecture of a communication system according to an embodiment of the present application. The communication system 100 includes a first communication device 110, a first communication device 111, a second communication device 120, a third communication device 130, a third communication device 131, and a third communication device 133. Wherein the second communication device may communicate with at least one third communication device, such as the third communication device 130, via an Uplink (UL) and a Downlink (DL). Signals transmitted between the second communication device and the third communication device, such as upstream signals or downstream signals, may also be amplified and/or forwarded by the first communication device.

Specifically, the first communication device has a first function of amplifying and/or forwarding the received signal, for example, the first communication device may receive a downlink signal from the second communication device, amplify the downlink signal received from the second communication device, and forward the amplified downlink signal to the third communication device. Alternatively, the first communication device may receive the uplink signal from the third communication device, amplify the uplink signal received from the third communication device, and forward the amplified uplink signal to the second communication device. The first communication device may also be referred to as a relay or a relay node, the relay may be a network device, such as a repeater, or the relay may also be one or more terminal devices for providing cooperative transmission for other terminal devices, which is not limited in this application.

The relay in the embodiment of the present application may have various possible forms, such as a decode-and-forward relay, an amplify-and-forward relay, a compress-and-forward relay, and the like. The decoding forwarding relay means that the relay decodes the received signal, re-encodes the signal, amplifies the re-encoded signal and sends the signal. The decoding and forwarding relay decodes the received signal, re-encodes the decoded signal, and then amplifies and/or forwards the decoded signal, so that errors and noise can be prevented from being accumulated, and the decoding accuracy of a receiving party is improved. Amplify-and-forward relay refers to relay that does not decode the received signal, but directly amplifies and/or forwards the received signal. Because the received signals do not need to be coded and decoded, the amplifying and forwarding relay can reduce the transmission delay of the signals. The compression forwarding relay means that the relay decodes the received signal, compresses the signal after decoding, then re-encodes the signal, and amplifies and/or forwards the re-encoded signal. The compression forwarding relay can effectively improve the data forwarding rate due to the compression of the signals.

The second communication device may be a network device, such as an access network device. An access network device (also called Radio Access Network (RAN) device) is a device that provides a terminal with a wireless communication function. The access network device may be configured to interconvert received air frames and Internet Protocol (IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network. The access network device may also coordinate attribute management for the air interface. Access network devices include, but are not limited to: next generation base stations (G nodeB, gNB), evolved node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (e.g., home evolved node B, or home node B, HNB), Base Band Unit (BBU), transmission point (TRP), Transmission Point (TP), mobile switching center, etc. in 5G, 6G, and even 7G.

It should be understood that the access network equipment corresponds to different equipment on different systems, such as in the fourth generation mobile communications technology (the 4)^thgeneration, 4G) system can correspond to eNBThe 5G system corresponds to an access network device in 5G, for example, a gNB. The technical solution provided in the embodiment of the present application may also be applied to a future mobile communication system, such as a 6G or 7G system, and therefore the second communication device in fig. 1 may also correspond to an access network device in the future mobile communication system.

The third communication device may be a terminal device. A terminal device (also referred to as UE) is a device with wireless transceiving function, and can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like. The terminal device can be used for, but is not limited to, 5G, 6G or even 7G communication systems.

By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable equipment can also be called wearable smart device or intelligent wearable equipment etc. is the general term of using wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application function, and need to be matched with other equipment such as a smart phone for use, such as various smart bracelets, smart helmets, smart jewelry and the like for physical sign monitoring.

The terminal device in the embodiment of the present application may also be an on-board module, an on-board component, an on-board chip, or an on-board unit that is built in the vehicle as one or more components or units, and the vehicle may implement the method of the present application through the built-in on-board module, the on-board component, the on-board chip, or the on-board unit.

The number of the first communication device, the second communication device, and the third communication device included in the communication system is not specifically limited in the embodiments of the present application. In the communication system, a plurality of first communication apparatuses may exist, a plurality of second communication apparatuses may exist, or a plurality of third communication apparatuses may exist.

It should be understood that one second communication device may serve a plurality of third communication devices. A first communication device may also amplify and/or retransmit signals received from one or more second communication devices, and may also amplify and/or retransmit signals received from one or more third communication devices. The second communication device, part or all of the plurality of first communication devices, and part or all of the plurality of third communication devices shown in fig. 1 may implement the technical solution provided by the embodiment of the present application.

It should also be understood that the terms "system" and "network" in the embodiments of the present application may be used interchangeably. "plurality" means two or more, and in view of this, a plurality may also be understood as "at least two" in the embodiments of the present application. "at least one" is to be understood as meaning one or more, for example one, two or more. For example, the inclusion of at least one means that one, two or more are included, and does not limit which is included. For example, at least one of A, B and C is included, then inclusion can be A, B, C, A and B, A and C, B and C, or A and B and C. Similarly, the understanding of the description of "at least one" and the like is similar. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" generally indicates that the preceding and following related objects are in an "or" relationship, unless otherwise specified.

Unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing between a plurality of objects, and do not define the order, sequence, priority, or importance of the plurality of objects, and the descriptions of "first", "second", etc., do not define that the objects are necessarily different.

Example one

Please refer to fig. 2, which is a flowchart illustrating a communication method according to an embodiment of the present application. The method specifically comprises the following steps:

step S201, the first communication device receives a first signal from the third communication device, where the first signal may be one or more of the following signals: data signals, control signals, reference signals, and synchronization signals.

The first signal may be a signal transmitted by a third communication device. The signal may be a signal sent by the third communication device to the second communication device, or may also be a signal sent by the third communication device to another communication device, which is not limited in this application. In a scenario where the second communication device is a network device and the third communication device is a terminal device, if the first signal is a signal sent by the third communication device to the second communication device, the first signal may also be referred to as an uplink signal.

In one possible design, the second communication device may send second information to the first communication device indicating a time and/or frequency at which the first communication device received the first signal. After the first communication device receives the second information from the second communication device, the first signal may be received from the third communication device at a time and/or frequency indicated in the second information. The time and/or frequency indicated in the second information may also be understood as the time and/or frequency that the second communication device is configured for the first communication device to listen to when and/or frequency that the third communication device transmits a signal.

It should be noted that the time and/or the frequency indicated in the second information may also refer to a frequency of a received signal or a transmitted signal configured for the first communication device by the second communication device, where the received signal may include a signal received by the first communication device from the second communication device, the third communication device, or another communication device, and the transmitted signal may include a signal transmitted by the first communication device to the second communication device, the third communication device, or another communication device, which is not limited in this application.

The second information is one or more of time information, frequency information and period information. Specifically, the time information may include the number and/or the position of a slot, a symbol, a subframe, or a frame used for transmitting the first signal in the first time unit, where the position may include a number, an index, and the like, and may be an absolute number or a relative number, which is not limited in this application. The frequency information may include one or more of the following information: frequency point information, bandwidth information and duplex information. The frequency point information refers to a frequency point where the first signal is located, and may also be understood as a frequency point where the third communication device sends a signal to the second communication device, or a working frequency point of the third communication device. The bandwidth information refers to a frequency bandwidth occupied by the first signal, and may also refer to a system bandwidth of the first communication device, the second communication device, or the third communication device, and the duplex information refers to Time Division Duplex (TDD) or Frequency Division Duplex (FDD). The period information refers to a transmission period of the first signal, and may also be understood as a repetition period of the first time unit. For example, the first time unit may be a radio frame, the time information is used to indicate the number of subframes used for transmitting the first signal and the starting position of the subframe in the radio frame, and the period information is a repetition period of the radio frame.

Step S202, the first communication device determines a first power value according to the first signal.

The first power value is used for measuring the energy of the received first signal, the first communication device can measure the first signal, and the first power value is determined according to the energy of the received first signal. For example, the first power value may be a Reference Signal Receiving Power (RSRP), or may be another parameter measured by the first communication device for measuring the energy of the first signal, which is not limited in this application.

Step S203, when the first power value is greater than or equal to the first threshold, the first communication device activates a first function, where the first function is to amplify and/or forward the received signal.

In this embodiment, after determining the first power value, the first communication device may determine a size relationship between the first power value and the first threshold. In one possible design, the first communication device may activate the first function if the first power value is greater than a first threshold, otherwise the first communication device may determine not to activate the first function if the first power value is less than or equal to the first threshold. In another possible design, the first communication device may activate the first function if the first power value is greater than or equal to a first threshold, otherwise the first communication device may determine not to activate the first function if the first power value is less than the first threshold. I.e. for the case of equality, one of the branches can be put in.

The first function refers to amplifying and/or forwarding the received signal. In this embodiment, the first communication device may receive signals from the second communication device and the third communication device, and it may be understood that a signal received by the first communication device from the second communication device is a downlink signal, and a signal received by the first communication device from the third communication device is an uplink signal. As such, activating the first function of the first communication device may include: the first communication device amplifies the signal received from the third communication device and then forwards the signal to the second communication device, and the first communication device amplifies the signal received from the second communication device and then forwards the signal to the third communication device. It should be noted that, here, the operation of the first communication device amplifying the received signal before forwarding the signal is optional, and the first communication device may also directly forward the received signal to the corresponding receiving party without amplifying the signal.

In a possible design, considering that the purpose of activating the first function is to improve the transmission performance of the third communication device (i.e. to improve the uplink transmission performance of the terminal device), it may also be that the first communication device amplifies and/or forwards only the signal received from the third communication device, i.e. the first communication device may amplify and/or forward only the received uplink signal.

Further, the second communication device may also configure the first communication device with respect to which signals the first function is specifically activated. The second communication device may transmit third information to the first communication device, the third information including one or more of time information, frequency information, and period information. The third information is used for instructing the first communication device to amplify and/or forward the signal received from the time and/or frequency corresponding to the third information. The specific implementation of the time information, the frequency information, and the period information in the third information may be similar to the time information, the frequency information, and the period information in the second information, and repeated parts are not described herein again, but it should be understood that the frequency information in the third information may also be used to indicate the frequency at which the first communication device retransmits the signal after activating the first function, that is, the first communication device retransmits the received signal at the frequency indicated by the frequency information after activating the first function. Optionally, the time and/or frequency indicated in the third information may be the same as the time and/or frequency indicated in the second information, that is, both the second communication device and the first communication device may be configured to monitor the time and/or frequency of the signal sent by the third communication device. Alternatively, the third information and the second information may be the same information.

The second communication device may also configure the first communication device with power to forward the signal after activating the first function. Specifically, the second communication device may transmit power information to the first communication device, the power information being used by the first communication device to determine the power of the retransmitted signal. In this way, the first communication device may forward the received signal according to the power information after activating the first function. For example, the first communication device may transmit a signal received from the third communication device after activation of the first function to the second communication device according to the forwarding power determined based on the power information.

It is understood that, when the distance between the first communication device and the third communication device is closer, the energy of the first signal received by the first communication device from the third communication device is larger, and accordingly, the first power value is larger. Therefore, in the embodiment of the present application, the distance between the first communication device and the third communication device may be estimated according to the first power value. If the first power value is greater than or equal to the first threshold, it may indicate that the first power value is greater, that is, the first communication device is closer to the third communication device, and at this time, the first function of the first communication device is activated, so that the transmission performance of the third communication device may be improved by effectively using the first communication device.

It should be noted that, in the embodiments of the present application, activating the first function may be understood as turning on the first function, and deactivating the first function may be understood as turning off the first function. The first function may also be referred to as a relay function, a relay forwarding function, an amplify-and-forward function, or the like, or may have another name, and the present application is not limited thereto.

And step S204, the first communication equipment sends the amplified and/or forwarded signal to the second communication equipment.

After activating the first function of the first communication device, the first communication device may also receive a second signal from the third communication device, the second signal being one or more of: data signals, control signals, reference signals, and synchronization signals. The second signal may be the same or different type from the first signal received by the first communication device from the third communication device, and the application is not limited thereto. For example, the first signal and the second signal may both be data signals, or the first signal may be a data signal and the second signal may be a control signal.

Similar to the processing of the first signal, the first communication device may determine a second power value based on the received second signal. Deactivating the first function of the first communication device in case the second power value is smaller than or equal to a second threshold value, the second threshold value being smaller than the first threshold value.

For example, in the state where the first function is activated, the first communication device may receive a second signal from the third communication device, and determine the second power value according to an energy level of the received second signal, for example, RSRP of the second signal. In one possible design, the first communication device may deactivate the first function if the second power value is less than or equal to the second threshold, otherwise, the first communication device may determine to continue to keep the first function in the activated state if the second power value is greater than the second threshold. In another possible design, the first communication device may deactivate the first function if the second power value is less than the second threshold, otherwise, the first communication device may determine to continue to keep the first function in the activated state if the second power value is greater than or equal to the second threshold.

Optionally, the time and/or frequency for the first communication device to receive the second signal may be the same as the time and/or frequency for the first communication device to receive the first signal indicated in the second information and the time and/or frequency for the first communication device to forward the signal indicated in the third information, and both of them are configured for the first communication device by the second communication device and are used for monitoring the time and/or frequency for the second communication device to transmit the signal.

That is, the second communication device may configure the first communication device to listen to the time and/or frequency at which the third communication device transmits the signal by transmitting the second information, so that the first communication device may continuously listen to the uplink signal transmitted by the third communication device to the second communication device at the time and/or frequency indicated by the second information, measure the uplink signal, and determine the first power value, which may be the received power of the uplink signal received by the first communication device from the third communication device.

In connection with the example in fig. 3, at a first time (t1), a first power value corresponding to an uplink signal received by the first communication device from the third communication device is greater than or equal to a first threshold, and the first communication device activates the first function. Between the first time (t1) and the fifth time (t5), the first power value corresponding to the uplink signal received by the first communication device from the third communication device is greater than or equal to the first threshold, so that the first communication device keeps activating the first function, amplifies the uplink signal received by the third communication device, and forwards the amplified uplink signal to the second communication device, so as to enhance the uplink transmission performance of the third communication device. At a fifth time (t5), the first power value corresponding to the uplink signal received by the first communication device from the third communication device is less than or equal to the second threshold, and the first communication device may deactivate the first function and stop forwarding the uplink signal received from the third communication device to the second communication device.

In this embodiment, after activating or deactivating the first function, the first communication device may further send status information to the second communication device, where the status information is used to indicate a current state of the first function of the first communication device, that is, an activated state or a deactivated state.

It should be noted that in the embodiment of the present application, when determining whether to activate or deactivate the first function of the first communication device, the mentioned first threshold and the second threshold may be predefined by the system or predefined, and may also be configured by the second communication device. The "predefined" may be understood as defining, predefining, storing, pre-negotiating, pre-configuring, curing, pre-firing, etc., and will not be described in detail below. The "configured by the second communication device" may be understood as that the second communication device may transmit the information indicating the first threshold value and/or the second threshold value to the first communication device in a MAC message, a Radio Resource Control (RRC) message, a system broadcast message, and so on. The information indicating the first threshold and the information indicating the second threshold may be sent in the same manner or in different manners, and the information indicating the first threshold and the information indicating the second threshold may be sent in the same message or in different messages, which is not limited in this application.

As such, the first threshold and the second threshold in the embodiment of the present application may have the following several possible implementations:

the implementation mode is as follows: the first threshold value and/or the second threshold value are both system predefined or predefined.

The implementation mode two is as follows: the second communication device configures the first threshold and/or the second threshold.

In this implementation, the second communication device may configure the first threshold and the second threshold at the same time, may configure only the first threshold, or configure only the second threshold. The configuration of the first threshold and the second threshold by the second communication device may indicate that the first communication device determines whether to activate the first function according to a comparison result between the first power value and the configured first threshold, and determines whether to deactivate the first function according to a comparison result between the second power value and the configured second threshold.

The second communication device may only configure the first threshold, and the first communication device may determine whether to activate the first function according to a comparison result between the first power value and the configured first threshold, but there is no limitation on how the first communication device deactivates the first function, and the first communication device may deactivate the first function in other ways besides deactivating the first function according to the second threshold, for example, the first communication device may deactivate the first function after receiving indication information indicating that the first function is deactivated from the second communication device.

The second communication device may only configure the second threshold, and the first communication device may determine whether to deactivate the first function according to a comparison result between the second power value and the configured second threshold, but there is no limitation on how the second communication device activates the first function, and the second communication device may also deactivate the first function in other ways besides activating the first function according to the first threshold, for example, the first communication device may activate the first function after receiving indication information indicating that the first function is activated from the second communication device.

Specifically, the second communication device may configure the first threshold and the second threshold, where the second communication device sends first information to the first communication device, and the first information is used to indicate the first threshold and the second threshold. In particular, in one possible design, the first information may directly indicate the value of the first threshold and the value of the second threshold. In another possible design, the first information may also indicate an index corresponding to the first threshold or another parameter for determining the first threshold, and an index corresponding to the second threshold or another parameter for determining the second threshold, and the first communication device determines the first threshold according to the index or the parameter corresponding to the first threshold and a predefined correspondence between the index or the parameter corresponding to the first threshold and the first threshold, and determines the second threshold according to the index or the parameter corresponding to the second threshold and a predefined correspondence between the index or the parameter corresponding to the second threshold and the second threshold. In yet another possible design, the first information may also indicate a value of the first threshold, and an index or other parameter for determining the second threshold corresponding to the second threshold. In yet another possible design, the first information may also indicate an index corresponding to the first threshold or other parameters for determining the first threshold, and a value of the first threshold.

The second communication device may configure only the first threshold value, and the second communication device may send first information to the first communication device, where the first information is used to indicate the first threshold value. In one possible design, the first information may directly indicate a value of the first threshold; in another possible design, the first information may also indicate an index corresponding to the first threshold or another parameter for determining the first threshold, and the first communication device determines the first threshold according to the index or the parameter corresponding to the first threshold and a predefined correspondence between the index or the parameter corresponding to the first threshold and the first threshold.

The second communication device may configure only the second threshold value, and the second communication device may send first information to the first communication device, where the first information is used to indicate the second threshold value. In one possible design, the first information may directly indicate a value of the second threshold; in another possible design, the first information may also indicate an index corresponding to the second threshold or another parameter for determining the second threshold, and the second threshold is determined by the first communication device according to the index or the parameter corresponding to the second threshold and a predefined correspondence between the index or the parameter corresponding to the second threshold and the second threshold.

The implementation mode is three: the second communication device configures a first threshold value, the second threshold value or a first offset value of the second threshold value relative to the first threshold value being system predefined or predefined.

In this implementation, for the specific implementation that the second communication device configures the first threshold, reference may be made to the description in the second implementation, and details are not repeated here.

The first communication device may derive the second threshold value from the first threshold value and the first offset value if a first offset value of the second threshold value relative to the first threshold value is predefined. In this embodiment, the second threshold is smaller than the first threshold, and a first offset value of the second threshold relative to the first threshold may be defined as a difference between the second threshold and the first threshold, or an absolute value of the difference between the second threshold and the first threshold. Thus, if the first offset value is the difference between the second threshold value and the first threshold value, the first communication device may add the first offset value to the first threshold value to obtain the second threshold value, and if the first offset value is the absolute value of the difference between the second threshold value and the first threshold value, the first communication device may subtract the first offset value from the first threshold value to obtain the second threshold value.

The implementation mode is four: the second communication device configures the first threshold and a first offset value of the second threshold relative to the first threshold.

In this implementation, the second communication device may configure the first threshold and the first offset value, such that the second communication device sends first information to the first communication device, where the first information is used to indicate the first threshold and the first offset value. Specifically, in one possible design, the first information may directly indicate a value of the first threshold and a value of the first offset value; in another possible design, the first information may also indicate an index or parameter corresponding to the first threshold value and an index or parameter corresponding to the first offset value; in yet another possible design, the first information may further indicate an index or parameter corresponding to a value of the first threshold and the first offset value, or a value of the index or parameter corresponding to the first threshold and the first offset value.

The implementation mode is five: the second communication device configures a second threshold value, the first threshold value or a second offset value of the first threshold value relative to the second threshold value being system predefined or predefined.

In this implementation, for a specific implementation of configuring the second threshold by the second communication device, reference may be made to the description in the second implementation, and details are not described here again.

If a second offset value of the first threshold value relative to the second threshold value is predefined, the first communication device may obtain the first threshold value according to the second threshold value configured by the second communication device and the second offset value. The second offset value may be defined as a difference between the first threshold value and a second threshold value, and since the first threshold value is greater than the second threshold value, the second offset value is a positive number, and the first communication device may add the second threshold value to the second offset value to obtain the first threshold value.

The implementation mode is six: the second communication device configures a second threshold and a second offset value of the first threshold relative to the second threshold.

In this implementation, the specific implementation manner of configuring the second threshold and the second offset value by the second communication device may be similar to the manner of configuring the first threshold and the first offset value by the second communication device described in the fourth implementation manner, and is not described herein again.

Seventh implementation, the first threshold is predefined or predefined by the system, and the second communication device configures the first offset value.

Eighth implementation, the first threshold is system predefined or predefined and the first offset value is predefined.

In the ninth implementation manner, the second communication device configures the second threshold, and the second communication device configures the second offset value.

Implementation ten, the second threshold is system predefined or predefined, and the second communication device configures the second offset value.

The seventh to tenth implementation manners may be implemented with reference to the foregoing implementation manners, and are not described herein again.

It should be noted that, for the first information mentioned in the first to tenth implementations, the first communication device may receive the first information before receiving the first signal in step S201, or may receive the first information after receiving the first signal in step S201, and the application is not limited thereto. That is, there is no chronological association between the first communication device receiving the first information and the first communication device receiving the first signal. It can also be understood that there is no chronological association between the transmission of the first information by the second communication device and the transmission of the first signal by the third communication device.

The first offset value and the second offset value in the embodiment of the present application may also be collectively referred to as "first offset value". When the second communication device is configured with the first threshold, "the first offset value" specifically refers to an offset value of the second threshold relative to the first threshold, that is, the first offset value mentioned in the second implementation; the "first offset value" specifically refers to an offset value of the first threshold value with respect to the second threshold value when the second communication device is configured with the second threshold value, i.e. the second offset value mentioned in this fifth implementation manner. It will be appreciated that the absolute value of the offset value of the second threshold relative to the first threshold is equal to the absolute value of the offset value of the first threshold relative to the second threshold.

The system mentioned in the embodiments of the present application is predefined, and may also be referred to as predefined.

It should also be noted that one or more of the first threshold, the second threshold, the first offset value, the second offset value may be associated with frequency information indicated in the second information or the third information. Specifically, the frequency information indicated in the second information or the third information belongs to a first frequency set, and one or more of the first threshold, the second threshold, the first offset value, and the second offset value belongs to a first value set, and the first frequency set is associated with the first value set. In this way, the second communication device may determine, according to the frequency information indicated in the second information or the third indication information, the first frequency set to which the frequency information belongs, and further determine one or more of the first threshold, the second threshold, the first offset value, and the second offset value from the first value set corresponding to the first frequency set. It should be understood that when the frequency sets to which the frequency information belongs are different, the values of one or more of the first threshold, the second threshold, the first offset value and the second offset value associated with the frequency information are also different, that is, the value sets corresponding to different frequency sets are different.

In the embodiment of the application, whether to activate or deactivate the first function of the first communication device may be determined according to the energy of the signal received from the third communication device, so that the first function of the first communication device located near the third communication device may be accurately activated, thereby effectively improving the transmission performance of the third communication device.

Example two

In order to save the overhead of control information transmission, the present application proposes a mechanism for scheduling multiple transport blocks using one downlink control information. Since New Data Indicator (NDI), Hybrid Automatic Repeat reQuest (HARQ) process information, the number of scheduled HARQ processes, frequency hopping, Redundancy Version (RV), and other scheduling information need to be indicated in Downlink Control Information (DCI), which may seriously increase the bit overhead of the DCI, and may sharply decrease the performance of the control channel. In view of this problem, the present application provides the following means to solve.

For a CEMode a user, in DCI, RV and Frequency Hopping (FH) information need to be indicated, where an RV field is 2 bits for indicating that RV is one of {0,2,3,1}, and a frequency hopping field is 1 bit for indicating whether frequency hopping is needed. When the PUSCH/PDSCH transmitted is configured to repeat a plurality of subframes, the RV used by the first subframe is indicated by the DCI, and the RV used by the subsequent repeated subframes is cyclic, wherein the cyclic sequence is 0,2,3 and 1. It can thus be seen that all RVs are transmittable after a certain number of repetitions, when it is not important whether to indicate a RV. For frequency hopping, when there is no repetition, i.e., the number of repetitions is only 1, the FH indication is meaningless because only one subframe is transmitted and no frequency hopping is possible. The frequency hopping is of a certain granularity, i.e. frequency hopping granularity

) The frequency hopping granularity is FDD {1,2,4,8}, TDD{1,5,10,20}. When the frequency hopping granularity is larger than 1 frame, the frequency hopping granularity is k, k>The frequency hopping indication is also meaningless when the number of repetitions is less than or equal to k at 1. In view of the background and the features, the present invention provides the following means.

The terminal equipment receives control information sent by the network equipment, such as downlink control information, DCI. The control information comprises a first field and a second field, the first field is used for indicating first information, the second field is used for indicating the number of times of repetition, and the first information is RV and/or frequency hopping. The terminal equipment determines frequency hopping and/or RV according to the first field and determines the repetition times according to the second field; and the terminal equipment transmits information to the network equipment according to the determined first information and the repetition times. Here, the transmission may be transmission or reception. Correspondingly, the network device sends, the corresponding terminal device receives, and the network device receives the corresponding terminal device sending.

In an implementable manner, when the number of repetitions indicated in the second field is greater than a first threshold, the first information is frequency hopping information; when the number of repetitions indicated in the second field is less than a first threshold, the first information is an RV. Optionally, when the number of repetitions indicated in the second field is equal to a first threshold, the first information is frequency hopping information or RV.

In an implementable manner, the first threshold is a number greater than 1, for example, the first threshold is 2, or the first threshold is 4. When the repetition number is greater than 2 or 4, the RV may transmit at least 2 or 4 versions, and the decoding success probability is higher at this time, so it is not necessary to indicate the RV used by the first subframe in the DCI, and therefore the first field is used to indicate the FH to improve the coverage, which may reduce the bit overhead of the DCI and improve the coverage and decoding success probability.

In one possible implementation, the first threshold is related to the second parameter. For example, the second parameter is frequency hopping granularity, the first threshold is x when the frequency hopping granularity belongs to a first set of granularities, the first threshold is y when the frequency hopping granularity belongs to a second set of granularities, where the first set of granularities and the second set of granularities include one or more frequency hopping granularity values, and there is at least one element that belongs to the first set of granularities but not to the second set of granularities, i.e., the first set of granularities and the second set of granularities are different. x and y are different. Or, the first threshold is x when the frequency hopping granularity belongs to a first set of granularities, the first threshold is y when the frequency hopping granularity belongs to a second set of granularities, the first threshold is z when the frequency hopping granularity belongs to a third set of granularities, wherein the first, second, and third sets of granularities comprise one or more frequency hopping granularity values, and there is at least one element that belongs to the first set of granularities but not to the second set of granularities and not to the third set of granularities, i.e. the first, second, and third sets of granularities are different from each other. x, y and z are different from each other.

For example, when the hopping granularity is 1, i.e., the first set of hopping granularities is {1}, the first threshold is 1; when the hopping granularity is greater than 1, i.e. the second set of hopping granularities is {2,4,8} for FDD, {5,10,20} for tdd, the first threshold is 2 or 4.

For example, for TDD, when the hopping granularity is 1, i.e., the first set of hopping granularities is {1}, the first threshold is 1; when the hopping granularity is greater than 1, that is, the second set of hopping granularities is {5,10,20} fordtdd, the first threshold is 2 or 4. For FDD, when the hopping granularity is 1, i.e. the first set of hopping granularities is {1}, the first threshold is 1; when the frequency hopping granularity is larger than 1 and smaller than 4, namely the second frequency hopping granularity set is {2}, the first threshold value is 2; when the hopping granularity is greater than or equal to 4, i.e., the third set of hopping granularities is {4,8}, the first threshold is 4.

For example, when the hopping granularity is 1, i.e., the first set of hopping granularities is {1}, the first threshold is 1; when the frequency hopping granularity is greater than 1 and less than 4, namely the second frequency hopping granularity set is {2} for FDD, the first threshold value is 2; when the frequency hopping granularity is greater than or equal to 4, i.e. the third set of frequency hopping granularities is {4,8} for FDD, {5,10,20} for TDD, the first threshold is 4.

In one possible implementation, the first threshold is 2 or 4 for FDD and 1 for TDD.

The network device determines control information, such as downlink control information, DCI. The control information comprises a first field and a second field, the first field is used for indicating first information, the second field is used for indicating the number of times of repetition, and the first information is RV and/or frequency hopping. The network equipment sends control information to the terminal equipment; and the network equipment transmits information to the terminal equipment according to the determined control information. The transmission may be either transmission or reception. Correspondingly, the network device sends, the corresponding terminal device receives, and the network device receives the corresponding terminal device sending.

EXAMPLE III

In a communication system, a Downlink Control Information (DCI) is usually used to schedule a transport block or schedule a transport block carried by a data channel. The data channel may be a physical downlink data channel or a physical uplink data channel.

In order to reduce the overhead of DCI transmission and save transmission resources, multiple data channels may be scheduled by using one DCI, or multiple transport blocks may be scheduled by using one DCI.

As shown in fig. 4, when one DCI schedules multiple transport blocks, the DCI carrying downlink control information needs to indicate the number of the scheduled transport blocks and indicate the HARQ process number (or HARQ process index) corresponding to each transmission.

For example, when 8 transport blocks are scheduled by one DCI, the DCI needs 8 bits to indicate the scheduled transport blocks in a bitmap indication manner, and needs 8 bits to indicate whether each transport block is successfully received in the bitmap indication manner. This requires a maximum of 8+ 8-16 bits of overhead for the indication.

For another example, when 8 transport blocks are scheduled by one DCI, each transport block has 3 states. For example, the transport block is a new transmission, the transport block is a retransmission, and the transport block is a no transmission. Thus, there are a total of 3^8 combinations, which require 13 bits to indicate.

In the above scheme, the overhead of DCI is very large, and the present invention proposes the following scheme in order to reduce the bit overhead when multiple TBs are scheduled.

The terminal device receives control information, such as Downlink Control Information (DCI), transmitted by the network device. The control information is used for indicating first information, second information and third information, the first information is the number of the scheduled TB blocks or the number of the scheduled HARQ processes, the second information is a new data indicator (new data indicator), and the third information is the number of the scheduled HARQ processes or the HARQ process ID. The number of the scheduled TB blocks may also be referred to as the number of the scheduled HARQ processes.

In one implementation, the number of scheduled TB blocks indicated by the control information belongs to the first set. For example, the first set is {1,2,8}, i.e., the number of TB blocks scheduled at this time can only be 1,2 or 8. When the scheduled data is more, the number of the scheduled TB blocks can be indicated to be 8, when the scheduled data is relatively moderate, the number of the scheduled TB blocks can be indicated to be 2, and when the data approaches to the end, the number of the scheduled TB blocks can be indicated to be 1 or 2 to complete transmission, which does not affect the scheduling flexibility, but at this time, the overhead of the DCI can be effectively reduced.

In an implementation manner, the control information further includes a fourth information, and the fourth information is used to indicate a range of the number of scheduled TB blocks, for example, the fourth information indicates that the number of scheduled TB blocks is less than or equal to 2 or the fourth information indicates that the number of scheduled TB blocks is 8. For example, the fourth information includes 1 bit, which indicates that the number of the scheduled TB blocks is 1 or 2 when the bit is in the first state (e.g., the first state is 0), and indicates that the number of the scheduled TB blocks is 8 when the bit is in the second state (e.g., the second state is 1). Optionally, when the number of the TB blocks indicating scheduling is 1 or 2, 7 or 8 bits are used to indicate the number of the TB blocks scheduled, the NDI, and the HARQ process number scheduled. Optionally, when the number of TB blocks indicating scheduling is 8, 8 bits are used to indicate the NDI of each HARQ process. Optionally, when the number of TB blocks indicating scheduling is 1 or 2, the first field is used to indicate an RV of the first TB, the second field is used to indicate an RV of the second TB, the first field includes 2 bits, and the second field includes 1 bit. Optionally, when the number of TB blocks indicating scheduling is 1 or 2, the third field is used to indicate an RV of an initial-transmission TB, the fourth field is used to indicate an RV of a retransmission TB, the first field includes 1 or 2 bits, and the second field includes 1 or 2 bits.

And the terminal equipment transmits information to the network equipment according to the determined control information. Here, the transmission may be transmission or reception. Correspondingly, the network device sends, the corresponding terminal device receives, and the network device receives the corresponding terminal device sending.

The network device determines control information, such as Downlink Control Information (DCI). The control information is used for indicating first information, second information and third information, the first information is the number of the scheduled TB blocks or the number of the scheduled HARQ processes, the second information is a new data indicator (new data indicator), and the third information is the scheduled HARQ process number or the HARQ process ID. The number of the scheduled TB blocks may also be referred to as the number of the scheduled HARQ processes.

In an implementation manner, the control information further includes fourth information, where the fourth information is used to indicate a range of the number of scheduled TB blocks, for example, the fourth information indicates that the number of scheduled TB blocks is less than or equal to 2 or the fourth information indicates that the number of scheduled TB blocks is 8. For example, the fourth information includes 1 bit, which indicates that the number of the scheduled TB blocks is 1 or 2 when the bit is in the first state (e.g., the first state is 0), and indicates that the number of the scheduled TB blocks is 8 when the bit is in the second state (e.g., the second state is 1). Optionally, when the number of TB blocks indicating scheduling is 1 or 2, 7 or 8 bits are used to indicate the number of TB blocks scheduled, the NDI, and the HARQ process number scheduled. Optionally, when the number of TB blocks indicating scheduling is 8, 8 bits are used to indicate the NDI of each HARQ process. Optionally, when the number of TB blocks indicating scheduling is 1 or 2, the first field is used to indicate an RV of the first TB, the second field is used to indicate an RV of the second TB, the first field includes 2 bits, and the second field includes 1 bit. Optionally, when the number of TB blocks indicating scheduling is 1 or 2, the third field is used to indicate an RV of an initial-transmission TB, the fourth field is used to indicate an RV of a retransmission TB, the first field includes 1 or 2 bits, and the second field includes 1 or 2 bits.

The network device sends control information to the terminal device.

And the network equipment transmits information to the terminal equipment according to the control information. Here, the transmission may be transmission or reception. Correspondingly, the network device sends, the corresponding terminal device receives, and the network device receives the corresponding terminal device sending.

Example four

For some services, in order to reduce the overhead of control resources, reduce data transmission delay and save energy, services may be transmitted on predefined resources, that is, a user transmits signals on the pre-configured resources without dynamic Downlink Control Information (DCI) scheduling. This transmission is called a configured scheduled transmission, also called a pre-configured resource transmission or a pre-configured resource non-scheduled transmission. In particular, the pre-configured resource transmission may be a pre-configured uplink resource transmission (PUR), pre-configured resource. After the uplink data is transmitted, the base station may feed back, to the user, an ACK, or a scheduling retransmission, or an instruction to the user to perform a backoff (e.g., initiate random access or EDT), through a physical downlink control channel (e.g., a physical downlink control channel, MPDCCH, or a physical downlink control channel, PDCCH). The DCI may also carry some update information, such as one or more of Timing Advance (TA), repetition number, and power adjustment. However, no specific design is given for how or whether other information is carried in the DCI when the fallback is indicated in the DCI, so the following scheme is provided in the present invention.

The terminal device receives control information, such as Downlink Control Information (DCI), from the network device. The control information is used for indicating at least one of the following information: ACK, backspacing, continuously detecting a search space, TA, repetition frequency information and a power control parameter. Wherein the ACK is used to indicate a transmission success acknowledgement or the ACK is used to indicate that the transmission is successful and a search space does not need to be detected (optionally, where the search space does not need to be detected refers to a search space within the PUR period, the backoff is used to indicate the terminal device to initiate Random Access (RACH) or Early Data Transmission (EDT), the search space is continuously detected to indicate that the transmission of the terminal device is successful and the search space needs to be continuously detected, or the search space is continuously detected to indicate that the transmission of the terminal device is successful and the search space is continuously detected after a period of time (the search space is continuously detected after a period of time may refer to the search space is continuously detected after a period of time within the PUR period, at this time, the search space for transmitting the DCI and the search space detected after a period of time are within the same PUR period), the repetition number information may refer to the repetition number of the transmission information or an adjustment amount of the repetition number, and the power control parameter may be an adjustment amount of power or a used power value.

In an implementation manner, the control information includes a first field, a second field, and a third field, where the first field is used to indicate TA, the second field is used to indicate information of the number of repetitions, and the third field is used to indicate backoff. When the third field indicates a user backoff, all bits of the first and second fields are set to 1 or 0.

In an implementation manner, the control information includes a third field, and the third field is used to indicate fallback. When a third field indicates user fallback, all remaining (or remaining) bits in the DCI are set to 1 or 0. At this time, since the configuration information does not need to be updated when the user is instructed to rollback, all bits of all other fields may be set to 1 or 0, so as to further detect whether the indication information is correct, and reduce the false alarm probability.

In an implementation manner, the control information includes a fourth field, and the fourth field is used to indicate one or more of the following information: and backing off, ACK, and continuously detecting the search space. An optional fourth field includes 2 bits, a first state (e.g., 00) of which is used to indicate ACK, a second state (e.g., 01) is used to indicate that the search space needs to be detected, and a third state (e.g., 11 or 10) is used to indicate backoff. Optionally, when the fourth field indicates fallback, all remaining bits in the DCI are set to 1 or 0.

And the downlink control information indicates backspacing, and the terminal equipment initiates random access or data early transmission according to the backspacing indicating information.

And the downlink control information indicates ACK, and the terminal equipment stops detecting the search space in the PUR period.

Wherein the ACK is used to indicate a transmission success acknowledgement or the ACK is used to indicate that the transmission is successful and a search space does not need to be detected (optionally, where the search space does not need to be detected refers to a search space within the PUR period, the backoff is used to indicate the terminal device to initiate Random Access (RACH) or Early Data Transmission (EDT), the search space is continuously detected to indicate that the transmission of the terminal device is successful and the search space needs to be continuously detected, or the search space is continuously detected to indicate that the transmission of the terminal device is successful and the search space is continuously detected after a period of time (the search space is continuously detected after a period of time may refer to the search space is continuously detected after a period of time within the PUR period, at this time, the search space for transmitting the DCI and the search space detected after a period of time are within the same PUR period), the repetition number information may refer to the repetition number of the transmission information or an adjustment amount of the repetition number, and the power control parameter may be an adjustment amount of power or a used power value.

In an implementation manner, the control information includes a third field, and the third field is used for indicating the fallback. When a third field indicates user fallback, all remaining (or remaining) bits in the DCI are set to 1 or 0. At this time, since the configuration information does not need to be updated when the user is instructed to rollback, all bits of all other fields may be set to 1 or 0, so as to further detect whether the indication information is correct, and reduce the false alarm probability.

The network device sends control information to the terminal device.

In an implementation manner, the terminal device receives a fifth message of the network device, where the fifth message is used to indicate the time and/or frequency domain granularity of the reserved resource, which may also be referred to as a time and/or frequency domain basic unit of the reserved resource. For example, the fifth message indicates a time domain granularity of L symbols or L slots, where L is an integer greater than or equal to 1. For example, when L ═ 2, it indicates granularity of 2 symbols, and when reserved resources are indicated by a bitmap of bits, each bit corresponds to whether two symbols are reserved or not.

And the network equipment sends the control information to the terminal equipment.

And the network equipment transmits information to the terminal equipment according to the reserved resource pattern.

In the method, whether the resource in the first time unit is available or not is indicated in the DCI, and the resource reservation is indicated more flexibly through the pattern of reserved resources, so that NR and eMTC coexist more flexibly and friendly.

EXAMPLE six

Currently, an evolved long-term evolution-advanced (LTE-a) system will continue to provide wireless communication services for its User Equipment (UE) in a short term (even a long term). In particular, enhanced machine type communication (eMTC) systems and their other evolution systems (background eMTC, FeMTC; even background eMTC, efmtc; additional MTC, AMTC) are systems derived on the basis of LTE, which operate in LTE systems and frequency bands.

In Downlink (DL) transmission, the eMTC system and its evolution system use Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) in the LTE system for synchronization. Since the primary synchronization signal and the secondary synchronization signal are sparse in the time domain, a long time is required for the synchronization process by using the two signals. Therefore, a resynchronization signal (RSS) is introduced, which is a periodic signal. The periodic RSS is added for the synchronous signals, so that the synchronous time can be reduced, and the power consumption of a user can be saved.

To further enhance the mobility performance of the UE, the synchronization information of the neighbor cell may be obtained by measuring the RSS of the neighbor cell. In order to measure the RSS, a measurement interval (measurement gap) is introduced in the prior art, and the user measures the RSS of the cell at a time specified by the measurement interval. The RSS appears periodically, and in order to match the RSS and the measurement interval in the time domain, there is a time domain offset in the RSS configuration, i.e. the start position of the RSS can be offset within the period range, so as to achieve the purpose of matching the measurement interval. However, when the serving cell is enabled to measure the RSS of the neighboring serving cell, how to ensure that the RSS of the neighboring cell matches the measurement interval of the serving cell is a problem to be solved. In order to solve the problems of the RSS measurement of the adjacent service cells and the mismatching of the measurement interval, the invention provides the following scheme.

In the prior art, the time domain offset of RSS is determined according to a cell Physical identifier (Physical layer cell identity) and the number of possible positions of RSS in one period. The time domain offset of the RSS is calculated (in units of granularity of the time domain offset) according to the following formula, for example:

wherein, the ORSS is a time domain offset (time offset) of the RSS in unit of time domain offset granularity, the PCID is a cell physical identifier, the NNB indicates the number of possible RSS narrow bands in the frequency domain, and the MRSS indicates the number of possible RSS time domain positions in one RSS period.

The actual time offset is ORSS × GRSS + Δ RSS frames (one frame is 10ms long, or a system frame), where GRSS/(10 MRSS) denotes the time offset granularity, and PRSS denotes the RSS period. Δ RSS is an offset after a time domain offset is a granularity offset or referred to as an extra time offset.

The terminal device receives first information, second information and third information sent by the network device, wherein the first information is used for indicating the time offset (time offset) granularity of the RSS, the second information is used for indicating the period of the RSS, and the third information is used for indicating the measurement interval. Optionally, the terminal device further receives fourth information sent by the network device, where the fourth information is used for the first parameter, and the first parameter is used for indicating an extra time offset, where the extra time offset is an extra offset after taking time offset granularity as a unit offset.

Optionally, the additional time offset is greater than or equal to zero and less than or equal to the time offset granularity.

Optionally, one or more of the first information, the second information, the third information, and the fourth information are included in the same system message or RRC message, and the rest of the messages are included in another one or more RRC messages or system messages.

Optionally, the time offset granularity is N times the measurement interval T or N times T/10, where N is an integer greater than or equal to 1. At this time, the time offset granularity is an integral multiple of the measurement interval, and as long as the position of the first RSS is aligned with the measurement interval, all subsequent possible time offsets are aligned with the measurement interval because the time offset granularity is an integral multiple of the measurement interval, so that the terminal device can measure the RSS in the measurement interval, and the measurement accuracy is improved. For example, a measurement interval of 40ms, the time-shift granularity is 40 × N ms or the time-shift granularity is 4 × N frames, or the time-shift granularity is 4 × N. For example, a measurement interval of 80ms, the time-shift granularity is 80 × N ms, or the time-shift granularity is 8 × N frames, or the time-shift granularity is 8 × N.

Optionally, the terminal device determines the time offset granularity according to one or more of the first information, the measurement interval and the RSS period. At this time, the time-shift granularity is different when different measurement intervals and/or RSS periods are different.

Optionally, the time offset granularity belongs to a first set of offset granularities when the measurement interval belongs to a first set of measurement intervals and/or the RSS period belongs to a first set of periods, wherein the first set of measurement intervals comprises one or more measurement intervals, the first set of periods comprises one or more RSS periods, and the first set of offset granularity comprises one or more time offset granularities. The time offset granularity belongs to a second set of offset granularity, wherein the second set of measurement intervals comprises one or more measurement intervals, the second set of periodicity comprises one or more RSS periods, and the second set of offset granularity comprises one or more time offset granularities, when the measurement intervals belong to the second set of measurement intervals and/or the RSS periods belong to the second set of periodicity. At least one of the following holds true, the first and second sets of measurement intervals being different, the first and second periodic sets being different, and the first and second sets of offset granularity being different. The first measurement interval set and the second measurement interval set may be different from each other in that at least one element in the first measurement interval set does not belong to the second measurement interval set, or at least one element in the second measurement interval set does not belong to the first measurement interval set. The first periodic set and the second periodic set may be different in that at least one element in the first periodic set does not belong to the second periodic set, or at least one element in the second periodic set does not belong to the first periodic set. The first set of offset granularities may be different from the second set of offset granularities in that at least one element in the first set of offset granularities does not belong to the second set of offset granularities, or at least one element in the second set of offset granularities does not belong to the first set of offset granularities.
