Description

Method and device for allocating uplink and downlink time resources

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for uplink and downlink time resource configuration.

Background

With the development of technology, a terminal device can be doubly linked with two systems. For example, the terminal device may be Double Connected (DC) with the LTE system and the NR system (i.e., EN-DC scenario). In an EN-DC scenario, a terminal device may communicate with a network device of a Long Term Evolution (LTE) system on one hand, and may communicate with a network device of a New Radio (NR) system on the other hand.

Due to the limitation of hardware design, in some cases, the terminal device cannot transmit uplink signals to two systems through two uplink radio frequency links at the same time. For example, the terminal device cannot transmit uplink signals to the network device of the LTE system and the network device of the NR system through two uplink radio frequency links at the same time.

In the prior art, in order to ensure that uplink signals are transmitted to two systems at different times (for example, uplink signals are transmitted to an LTE system and an NR system), a Time Division Multiplexing (TDM) mode may be configured for uplink transmission of the systems, and the uplink signals may be transmitted to the two systems on different subframes of one frame. However, in the prior art, in order to ensure that uplink signals are transmitted to the systems at different times, the TDM mode configuration that can be used by the systems (e.g., LTE systems) is relatively small, thereby affecting the scheduling flexibility of the systems.

Therefore, how to improve the flexibility of system scheduling becomes a problem that needs to be solved at present in a scenario where the terminal device performs dual link with two systems.

Disclosure of Invention

The application provides a method for configuring uplink and downlink time resources, which can increase the time resource configuration which can be used by a system under the scene that terminal equipment and two systems are in double link, thereby improving the flexibility of system scheduling.

In a first aspect, a method for configuring uplink and downlink time resources is provided, where the method includes: the method comprises the steps that terminal equipment receives first configuration information sent by first network equipment; the terminal equipment sends first uplink information on first time resources according to the offset information and first time resource configuration of a first system; and the terminal equipment transmits second uplink information on the second time resource according to the second time resource configuration in the second system.

It should be understood that, in this embodiment of the present application, the first time resource configuration may be used to indicate a configuration manner of a time resource for receiving uplink data and a time resource for sending downlink data on the same frequency channel by a terminal device, and may be understood as a configuration of uplink and downlink time resources.

The first time resource configuration may be a configuration in a TDM mode, or may be a configuration in a Time Division Duplex (TDD) mode. As an example, in an LTE system, there may be seven configurations for the first time resource configuration, for example, the uplink and downlink time resource configuration in configuration 0 may be DSUUDDSUUD, where for configuration 0, the terminal device may transmit uplink data on the first time resource, the terminal device may transmit uplink data, receive downlink data, transmit uplink pilot data on the second time resource, the terminal device may receive downlink data on the third time resource, and so on.

In the embodiment of the present application, a time resource may be understood as a subframe, a timeslot, or other resources that express a period of time, which is not specifically limited in this application.

The offset information indicated in the first configuration information in the embodiment of the present application may be offset or offset (offset) of the first time resource configuration. The offset information indicated in the first configuration information is not specifically limited in the embodiment of the present application, and may be offset for the first time resource configuration in units of subframes, or offset for the first time resource configuration in units of slots, or offset for the first time resource configuration in units of one symbol, or offset for the first time resource configuration in units of multiple symbols including at least one symbol, or offset for the first time resource configuration in units of time, or some combination of the foregoing offset manners.

It should be understood that the terminal device may transmit the first uplink information to the first system and the second uplink information to the second system on different time resources, respectively. That is to say, the terminal device may bias the first time resource configuration according to the offset information in the first configuration information, so that a first time resource for the terminal device to send the first uplink information to the first system and a second time resource for the terminal device to send the second uplink information to the second system are not overlapped in a time domain. Therefore, the uplink information can be sent to the first system and the second system by the terminal equipment at different time resources, and meanwhile, a first time resource configuration mode which can be used by the terminal equipment in the first system is increased or a second time resource configuration mode which can be used by the terminal equipment in the second system is increased, so that the flexibility of system scheduling can be improved.

In this embodiment of the application, the first system is not specifically limited, and may be an LTE system, an NR system, a third generation mobile communication technology (3G) system, a fourth generation mobile communication technology (4G) system, a PLMN network for future evolution, and the like.

In this embodiment, the network device that sends the offset information of the first time resource configuration of the first system to the terminal device is not specifically limited. As an example, the network device may be a device communicating with the terminal device in the first system, and may also be a device communicating with the terminal device in another system. For example, if the first system is an LTE system, the offset information of the first time resource configuration of the LTE system sent by the network device eNB in the LTE system to the terminal device may be also the offset information of the first time resource configuration of the LTE system sent by the network device gNB in the NR system to the terminal device, and may also be a network device in a future 5G network or a network device in a future evolved PLMN network.

terminal devices

116 and 122 over forward links 116 and 124, respectively, the transmitting antennas of network device 102 may utilize beamforming to improve signal-to-noise ratio of forward links 116 and 124. Moreover, mobile devices in neighboring cells can experience less interference when network device 102 utilizes beamforming to transmit to

terminal devices

116 and 122 scattered randomly through an associated coverage area, as compared to a manner in which a network device transmits through a single antenna to all its terminal devices.

At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or save in memory, etc.) a number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be contained in a transport block (or transport blocks) of data, which may be segmented to produce multiple code blocks.

Furthermore, the communication system 100 may be a public land mobile network PLMN (public land mobile network) network or device-to-device (D2D) network or machine-to-machine (M2M) network or other networks, which is illustrated in fig. 1 for ease of understanding only and is a simplified schematic diagram, and other network devices may be included in the network, which are not shown in fig. 1.

For convenience of description, the following description takes a terminal device as an example and describes in detail.

In a communication system, a terminal device may be doubly linked with two systems. In the following, an example is given in which one system is an LTE system and the other system is an NR system.

In the 5G communication system, a scenario (i.e., EN-DC scenario) in which an LTE system and an NR system are double-linked (DC) is introduced. In the EN-DC scenario, the UE may communicate with a network device of the LTE system on the one hand, and may communicate with a network device of the NR system on the other hand.

Fig. 2 is a schematic diagram of a UE communicating in an EN-DC scenario. As shown in fig. 2, when the UE210 operates in an EN-DC scenario, the UE210 may communicate with the network device eNB220 of the LTE system and the network device gNB230 of the NR system at the same time.

Specifically, UE210 may configure at least two radio frequency chains (RF chains), where one uplink 240 may be used to transmit uplink signals to eNB220 and another uplink 250 may be used to transmit uplink signals to gNB 230. UE210 may transmit uplink signals to eNB220 and to gNB230 over two uplink radio frequency links (link 240, link 250) simultaneously.

However, due to the hardware design constraints of the UE210, in some cases, the UE210 cannot transmit uplink signals to the eNB220 and the gNB230 through two uplink radio frequency links (link 240 and link 250) at the same time.

A detailed description of a scenario in which the UE210 cannot transmit uplink signals to the eNB220 and the gNB230 through two uplink radio frequency links at the same time is provided below.

As an example, the UE210 may generate cross modulation interference when transmitting uplink signals to network devices (e.g., eNB220, gNB230) via two uplink radio frequency links at the same time. For example, the UE210 may transmit an uplink signal at frequency f1 to the eNB220 via the uplink radio frequency link 240, and at the same time, the UE210 may also transmit an uplink signal at frequency f2 to the gNB230 via the uplink radio frequency link 250. Due to poor linearity of the radio frequency device (nonlinearity of the radio frequency device), an uplink signal with the frequency f1 and an uplink signal with the frequency f2 in the network interact with each other to generate harmonic interference signals. The generated harmonic interference signal may generate interference on the downlink signal received by the UE210, thereby affecting the reception of the downlink signal of the UE 210. Thus, UE210 is not able to transmit uplink signals to eNB220 and gNB230 over both uplink radio frequency links (link 240, link 250) simultaneously.

As another example, when the UE210 transmits uplink signals to network devices (e.g., eNB220, gNB230) via two uplink radio frequency links at the same time, two communication systems may not be able to dynamically and flexibly allocate transmission power. For the EN-DC scenario, the UE210 may have modems of both the LTE system and the NR system. For example, in some designs, the modems of the LTE system and the modems of the NR system may be integrated into one chip (the modems of the two systems are coupled to each other), and the modems of the LTE system may share the allocation information of the modems of the NR system to the uplink transmission power, so that the uplink transmission power of the LTE system may be dynamically and flexibly allocated, and the maximum transmission power of the UE210 may be avoided from being exceeded. For another example, in a design scheme in which a modem of the LTE system and a modem of the NR system are two independent modems (the modems of the two systems are not in a tight coupling relationship), the modems of the LTE system may not share information about allocation of the modems of the NR system to the uplink transmission power, so that the uplink transmission power of the LTE system cannot be dynamically and flexibly allocated. Thus, UE210 is not able to transmit uplink signals to eNB220 and gNB230 over both uplink radio frequency links (link 240, link 250) simultaneously.

In summary, for when the UE210 operates in an EN-DC scenario, the UE210 may transmit uplink signals to the eNB220 and the gNB230 through the uplink radio link at different times (time slots).

In the prior art, in order to ensure that uplink signals are transmitted to two systems (eNB 220 of the LTE system and gNB230 of the NR system) at different times, a Time Division Multiplexing (TDM) mode may be configured for uplink transmission of the LTE system when the 5G communication system is designed. Different uplink and downlink subframe configuration modes in the LTE system can be used, so that the UE210 can send uplink signals to the eNB220 and the gNB230 in different time slots.

It should be understood that a TDM pattern may be a pattern in which different signals are transmitted in different time segments of the same physical connection, the time for transmitting information provided to the entire channel may be divided into time slices (which may also be referred to as time slots), and the time slots may be allocated for use by each signal source.

The TDM mode (pattern) of the LTE system in the EN-DC scenario is described in more detail below with specific signaling:

subframe Assignment-r15::＝SEQUENCE{sa0，sa1，sa2，sa3，sa4，sa5，sa6}

in the above signaling, the signaling "TDM-PatternConfig-r 15 (TDM-pattern configuration-r 15)" may be used to indicate TDM pattern configuration by r15 version in the standard, the signaling "release NULL" may be used to indicate resource occupied by release invalid signaling, the signaling "setup SEQUENCE" may be used to indicate SEQUENCE number of the device, the signaling "HARQ-offset-r 15 (hybrid automatic repeat request-offset-r 15)" may be used to indicate offset of hybrid automatic repeat request (HARQ) by r15 version in the standard, the signaling "subframe Assignment-r 15:" ue nce { sa0, sa 84, sa2, sa3, sa4, sa5, sa5 } (SEQUENCE Assignment-r15, sa0, sa1, sa 5926 sa 202, sa 202 sa3, sa 94, sa3, sa 5926 sa 202 sa3, sa 5926 sa 56, sa 59sa 5926 sa 56, sa3, sa 59sa 3, sa 5926 sa3, sa 5926 sa3, sa1, sa2, sa3, sa4, sa5, sa6 }.

It should be understood that in the TDM mode of the LTE system, the frame has a length of 10s, and can be divided into 10 subframes with a length of 1 s. Uplink and downlink data may be transmitted on different subframes within the same frame. The TDM of the LTE system can support different uplink and downlink time ratios, and the uplink and downlink time ratios can be adjusted according to different service types so as to meet asymmetric service requirements of uplink and downlink. In the same frame, the configurations of different uplink and downlink subframes may include seven configurations shown in table 1: sa0, sa1, sa2, sa3, sa4, sa5, and sa6, and the specific configuration of the uplink and downlink subframes can be seen in table 1.

TABLE 1 uplink-downlink configurations (uplink-downlink configurations)

Wherein D in table 1 may be used to indicate a downlink subframe (downlink subframe) on which downlink data may be received; u may be used to represent an uplink subframe (uplink subframe) on which uplink data may be transmitted; s may be used to indicate a special subframe (special subframe) on which uplink data may be transmitted, downlink data may be received, and uplink pilot data may be transmitted.

As can be seen from table 1 above, in an EN-DC scenario, uplink and downlink subframe ratios in an LTE system may be configured in a TDM mode, so that the UE210 may send uplink signals to the eNB220 and the gNB230 in different time slots.

However, in the prior art, only the TDM pattern of the LTE system is configured, and in order to enable the UE210 to transmit uplink signals to the eNB220 and the gNB230 in different time slots, the TDM pattern of the LTE system that can be used is relatively small, which affects scheduling flexibility of the system.

The configuration of sa2 in table 1 above is explained as an example. If the TDM pattern is configured as sa2 in the LTE system (see table 1, uplink and downlink subframe configuration under sa2 configuration: dsudddsudsudd), when the UE210 communicates with the network equipment eNB22 of the LTE system, the UE210 may transmit uplink signals to the eNB220 in the LTE system only on subframe 2 and subframe 7 (subframe 2 and subframe 7 are uplink subframe U under sa2 configuration). In principle, when the TDM pattern is configured for sa2 in the LTE system, the UE210 may transmit uplink signals to the gNB230 in the NR system on the remaining subframes (e.g., subframe 0, subframe 1, subframe 3, subframe 4, subframe 5, subframe 6, subframe 8, subframe 9).

However, for the NR system, the NR system also needs to perform a TDM pattern during the actual operation of the system. When the frame structure (TDM pattern) of the NR system and the frame structure (TDM pattern) of the LTE system are matched with each other, in order to enable the UE210 to transmit uplink signals to the eNB220 and the gNB230 in different time slots, the available TDM patterns of the LTE system are relatively few, which may affect the scheduling flexibility of the system.

The following takes a frame structure of DDDSUDDDSU used in NR system as an example, and is described in detail with reference to fig. 3.

Fig. 3 is a diagram illustrating a frame structure of an LTE system and a frame structure of an NR system. The TDM patterns of the LTE system are sa1, sa2, sa4, and sa5 in fig. 3 as an example.

Referring to fig. 3, if the frame structure used in the NR system is DDDSUDDDSU, TDM patterns that the LTE system cannot use are sa1, sa 4.

Specifically, taking the TDM pattern of the LTE system as sa1 as an example, the UE210 may transmit an uplink signal to the eNB220 on subframe 8 (subframe 8 is an uplink subframe U in the frame structure of the LTE system), and meanwhile, the UE210 may also transmit an uplink signal to the gNB230 on subframe 8 (subframe 8 is a special subframe S in the frame structure of the NR system). Since the UE210 cannot simultaneously transmit uplink signals to the eNB220 and the gNB230, the TDM pattern that the LTE system cannot use is sa1 in the EN-DC scenario.

Taking the TDM pattern of the LTE system as sa4 as an example, the UE210 may transmit an uplink signal to the eNB220 on subframe 3 (subframe 3 is an uplink subframe U in the frame structure of the LTE system), and meanwhile, the UE210 may also transmit an uplink signal to the gNB230 on subframe 3 (subframe 3 is a special subframe S in the frame structure of the NR system). Since the UE210 cannot simultaneously transmit uplink signals to the eNB220 and the gNB230, the TDM pattern that the LTE system cannot use is sa4 in the EN-DC scenario.

Therefore, in the prior art, in order to ensure that uplink signals are transmitted to the systems at different times, the TDM mode configurations that can be used by the systems (e.g., LTE systems) are relatively few, which may affect the scheduling flexibility of the systems.

The embodiment of the application provides a method for configuring uplink and downlink time resources, which can increase the time resource configuration which can be used by a system under the scene that terminal equipment and two systems are in double link, thereby improving the flexibility of system scheduling.

Fig. 4 is a schematic flowchart of a method for configuring uplink and downlink time resources according to an embodiment of the present application. The flowchart shown in fig. 4 may include

steps

410 and 430, and the

steps

410 and 430 are described in detail below.

In step 410, the terminal device receives first configuration information sent by the first network device, where the first configuration information indicates offset information of first time resource configuration of the first system.

The first configuration information received by the terminal device in this embodiment may be used to indicate offset information of the first time resource configuration of the first system.

The offset information indicated in the first configuration information in the embodiment of the present application may be offset or offset (offset) of the first time resource configuration. The offset information indicated in the first configuration information is not specifically limited in the embodiment of the present application, and may be offset for the first time resource configuration in units of subframes, or offset for the first time resource configuration in units of slots, or offset for the first time resource configuration in units of one symbol, or offset for the first time resource configuration in units of multiple symbols including at least one symbol, or offset for the first time resource configuration in units of time, or some combination of the foregoing offset manners. The following description will be made in conjunction with specific embodiments, which will not be described in detail herein.

Step 420, the terminal device sends the first uplink information on the first time resource according to the offset information and the first time resource configuration.

The terminal device may send the first uplink information to the network device in the first system on the first time resource according to the offset information and the first time resource configuration.

Step 430, the terminal device sends the second uplink information on the second time resource according to the second time resource configuration of the second system.

The terminal device may send the second uplink information on the second time resource according to the second time resource configuration of the second system.

In the embodiment of the present application, the second system is not specifically limited, and may be an LTE system, an NR system, a 3G system, a 4G system, a PLMN network evolved in the future, or the like. As an example, the first system may be an LTE system and the second system may be an NR system. As another example, the first system is an NR system and the first system is an LTE system. As another example, the first system is an LTE system and the first system is an LTE system. As another example, the first system is an NR system.

In the embodiment of the application, the time resource allocation which can be used by the system can be increased under the scene that the terminal equipment and the two systems are in double link, so that the flexibility of system scheduling can be improved.

In the following, a specific implementation manner of the method for configuring uplink and downlink time resources mentioned in the embodiments of the present application is described in more detail by taking the first system as an LTE system and the second system as an NR system as an example, and combining specific signaling.

In the embodiment of the present application, in order to enable the terminal device to send uplink information to the eNB of the LTE system and the gNB2 of the NR system on different time resources, a TDM mode may be configured for uplink sending of the LTE system.

Specifically, uplink transmission of the LTE system may be configured through signaling TDM-pattern config-r15 (TDM-pattern configuration-r 15, which may correspond to the first time resource configuration above).

In order to enable the terminal device to send uplink information to the eNB of the LTE system and the gNB of the NR system on different time resources, and at the same time, improve flexibility of system scheduling, so as to increase TDM pattern configuration that can be used in the LTE system, in this embodiment of the present application, an offset (offset, which may correspond to offset information indicated in the first configuration information in the foregoing) may be configured again, so that compared with TDM pattern configuration of the NR system, the TDM pattern configuration of the LTE system after offset may ensure that the terminal device does not send uplink information to the LTE system and the NR system on the same subframe (which may correspond to the time resources in the foregoing) at the same time.

Specifically, the terminal device may receive configuration information, which may be used to indicate offset information of uplink and downlink time resource configuration of the LTE system.

It should be understood that the offset information of the uplink and downlink time resource configuration of the LTE system may be configured by the network device eNB in the LTE system for the terminal device, may also be configured by the network device gNB in the NR system for the terminal device, and may also be configured by the network device in other networks for the terminal device, which is not specifically limited in this application.

The offset information of the uplink and downlink time resource configuration configured in the embodiment of the present application is described in more detail below with reference to specific signaling.

In this embodiment of the present application, the offset information of the uplink and downlink time resource allocation may be offset for the first time resource allocation in units of subframes, may be offset for the first time resource allocation in units of slots, may be offset for the first time resource allocation in units of one symbol, may be offset for the first time resource allocation in units of multiple symbols including at least one symbol, may be offset for the first time resource allocation in units of time, or may be a combination of the foregoing offset manners.

In the embodiment of the present application, the first time resource allocation may be shifted by arbitrarily combining multiple types of the above-mentioned offset manners. As an example, the first time resource configuration may be shifted both in units of subframes and in units of one symbol. As another example, it is also possible that the first time resource configuration performs both an offset in units of subframes and an offset in units of a plurality of symbols including at least a symbol. As another example, it may also be that the first time resource configuration performs both an offset in units of subframes and an offset in units of time.

A specific implementation manner of biasing the first time resource configuration in units of subframes in the embodiment of the present application is described in more detail below with reference to specific signaling.

It should be understood that the offset of the subframe in the TDM mode configuration (time resource configuration) in the above signaling "subframe-offset-rxx inter (0 · 9)" may be an offset in units of subframes. The offset range of the subframe unit may be 0 to 9 subframes, so that the terminal device may be configured according to the TDM pattern after offset, and may send uplink information to the LTE system and the NR system on different time domains (time resources), respectively.

A specific implementation manner of biasing the first time resource allocation in units of symbols in the embodiment of the present application is described in more detail below with reference to specific signaling.

In the above signaling, the signaling "TDM-pattern config-r15 (TDM-pattern configuration-r 15)" may be used to indicate TDM pattern configuration by r15 version in the standard, the signaling "release NULL" may be used to indicate release of resources occupied by invalid signaling, the signaling "setup SEQUENCE" may be used to indicate SEQUENCE number of the device, the signaling "HARQ-offset-r 15 (hybrid automatic repeat request-offset-r 15)" may be used to indicate HARQ offset in r15 version in the standard, the signaling "subframe Assignment-r15 (subframe Assignment-r 15)" may be used to indicate subframe Assignment pattern in r15 version in the standard, and the signaling "symbol-offset-rxx INTEGER (0. 139) (symbol-offset-rxx. 139 (0. enumeration) may be used to indicate that the signaling" TDM-pattern configuration "TDM-pattern" configures resources corresponding to TDM-pattern (TDM-pattern) in r15 version in time (TDM-pattern configuration) And (4) biasing.

It should be understood that the offset of the subframe in the TDM mode configuration (time resource configuration) in the above signaling "symbol-offset-rxx inter (0 · 139)" may be an offset in units of symbols. The offset range of the symbol unit may be 0 to 139 symbols, so that the terminal device may transmit uplink information to the LTE system and the NR system on different time domains (time resources) according to the TDM mode configuration after the offset.

It should be understood that in the embodiment of the present application, biasing the TDM mode configuration in units of symbols may be biasing the TDM mode configuration in units of one symbol, or may also be biasing the TDM mode configuration in units of a plurality of symbols including at least a symbol.

A specific implementation manner of biasing the first time resource configuration in units of time in the embodiment of the present application is described in more detail below with reference to specific signaling.

In the above signaling, the signaling "TDM-pattern config-r15 (TDM-pattern configuration-r 15)" may be used to indicate TDM pattern configuration by r15 version in the standard, the signaling "release NULL" may be used to indicate resources occupied by release NULL signaling, the signaling "setup SEQUENCE" may be used to indicate serial number of the device, the signaling "HARQ-offset-r 15 (hybrid automatic repeat request-offset-r 15)" may be used to indicate HARQ offset in r15 version in the standard, the signaling "subframe Assignment-r15 (subframe Assignment-r 15)" may be used to indicate subframe Assignment pattern in r15 version, the signaling "time-fset-rxx enervated (TDM 0.1, ms0.2 ms1, 2 enumerator) (time-r 2) (TDM-2 ms configuration-r 15) may indicate that TDM-pattern configuration is corresponding to TDM-pattern configuration of TDM-pattern-r 632, and the signaling" release NULL "may be used to indicate that the TDM-pattern configuration is corresponding to TDM-pattern configuration (TDM-pattern) in TDM-pattern) of TDM 0.7 · s2, i-2 A time resource configuration).

It should be understood that the offset of the sub-frame in the TDM mode configuration (time resource configuration) in the above signaling "time-offset-rxx estimated (ms0.1, ms0.2 · ms1, ms2 ·)" may be an offset in absolute time. Wherein ms0.1 represents 0.1ms, ms0.2 represents 0.2ms, ms1 represents 1ms, and ms2 represents 2 ms. The TDM mode configuration is biased by taking the absolute time as a bias unit, so that the terminal device can respectively send uplink information to the LTE system and the NR system on different time domains (time resources) according to the biased TDM mode configuration.

A specific implementation manner of biasing the first time resource allocation in units of both subframes and one symbol in the embodiment of the present application is described in more detail below with reference to specific signaling.

In the signaling, a signaling "TDM-pattern config-r15 (TDM-pattern configuration-r 15)" may be used to indicate TDM pattern configuration by r15 version in the standard, a signaling "release NULL" may be used to indicate that resources occupied by invalid signaling are released, a signaling "setup SEQUENCE" may be used to indicate a SEQUENCE number of a device, a signaling "HARQ-offset-r 15 (hybrid automatic repeat request-offset-r 15)" may be used to indicate HARQ offset in r15 version, and a signaling "subframe Assignment-r15 (subframe Assignment-r 15)" may be used to indicate subframe Assignment pattern in r15 version.

The signaling "subframe-offset-rxx inter (0 · 9) (subframe-offset-rxx enumeration (0 · 9))" and the signaling "symbol-offset-rxx inter (0 · 139) (symbol-offset-rxx enumeration (0 · 139))" can be used to indicate that the TDM mode configuration in the signaling "TDM-pattern config-r 15" (corresponding to the first time resource configuration) is offset both in subframes and in one symbol. The terminal equipment can be configured according to the TDM mode after the offset, and can respectively send uplink information to the LTE system and the NR system in different time domains (time resources).

A specific implementation manner of biasing the first time resource allocation in units of both subframes and time in the embodiment of the present application is described in more detail below with reference to specific signaling.

The signaling "subframe-offset-rxx inter (0 · 9) (subframe-offset-rxx enumeration (0 · 9))" and the signaling "time-offset-rxx estimated (ms0.1, ms0.2 · ms1, ms2 · h) (time-offset enumeration (ms0.1, ms0.2 · ms1, ms2 · h))" can be used to indicate that the TDM mode configuration in the signaling "TDM-pattern config-r 15" (corresponding to the first time resource configuration) is offset both in subframes and in absolute time. The terminal equipment can be configured according to the TDM mode after the offset, and can respectively send uplink information to the LTE system and the NR system in different time domains (time resources).

It should be understood that, in the embodiments of the present application, the first time resource allocation may be shifted in any combination of the above-mentioned several offset manners (an offset in units of subframes, an offset in units of one symbol, an offset in units of a plurality of symbols including at least a symbol, and an offset in units of time). For the specific signaling, the signaling may refer to the signaling described above, and details are not repeated here.

The offset information for biasing the time resource configuration may indicate that the time resource configuration is biased forward, may also indicate that the time resource configuration is biased forward, and may also indicate that the time resource configuration is circularly biased, which is not specifically limited in this application.

It should be understood that, taking the first system as an LTE system and the second system as an NR system as an example, the forward offset of the time resource configuration may be used to represent frames in a TDM mode configuration in the LTE system but in advance with respect to the NR system. The time resource configuration biasing backward may be used to represent frames in TDM mode configuration in LTE systems but delayed a little with respect to NR systems.

A specific implementation of the method for configuring uplink and downlink time resources in the embodiment of the present application is described in more detail below with reference to a specific example. It should be noted that the example of fig. 5 is only for assisting the skilled person in understanding the embodiments of the present application, and is not intended to limit the embodiments of the present application to the specific values or specific scenarios illustrated. It will be apparent to those skilled in the art that various equivalent modifications or variations are possible in light of the example given in fig. 5, and such modifications and variations also fall within the scope of the embodiments of the present application.

The first system is an LTE system, and the second system is an NR system.

It should be understood that various methods of biasing the time resource configuration (TDM pattern configuration) are described above, and biasing the time resource configuration in units of subframes is described as an example in fig. 5.

Referring to fig. 3 above, the TDM patterns of the LTE system are sa1, sa2, sa4, and sa5 in fig. 3 as an example. Through the above analysis, in order to realize that the terminal device in fig. 3 can respectively send uplink signals to the LTE system and the NR system on different subframes, if the frame structure used in the NR system is DDDSUDDDSU, the TDM patterns that the LTE system cannot use are sa1 and sa 4.

Taking the TDM pattern that cannot be used by the LTE system as sa1 as an example, the subframe 8 is an uplink subframe U in the frame structure of the LTE system, and the terminal device may send an uplink signal to the LTE system on the subframe 8. The subframe 8 is a special subframe S in the frame structure of the NR system, and the terminal device may transmit an uplink signal to the NR system on the subframe 8. Therefore, in order to achieve time-staggered uplink transmission between the terminal device and the LTE system and uplink transmission of the NR system, the TDM pattern that cannot be used by the LTE system is sa 1. Similarly, in sa1 mode of the LTE system, there is also a case where the terminal device can simultaneously transmit an uplink signal to the LTE system and the NR system in subframe 3. It can also be understood that if the LTE system is a special subframe S or an uplink subframe U on one subframe, the NR system may not be S and U on that subframe.

In the embodiment of the present application, a TDM configuration mode (time resource configuration) is additionally offset, so that compared with the TDM mode configuration of an NR system, the TDM mode configuration of an LTE system after offset can ensure that a terminal device does not simultaneously send uplink information to the LTE system and the NR system in the same subframe (which may correspond to the time resource in the foregoing). Meanwhile, the configuration of the TDM pattern which can be used by the system can be increased in a bias mode, so that the flexibility of system scheduling can be enhanced.

With reference to fig. 5, it is described in detail that, after the TDM patterns that cannot be used in the LTE system are sa1 and sa4 in fig. 5 are shifted, the TDM patterns that can be used in the LTE system can be sa1 and sa4, so that the available TDM patterns are increased, and the flexibility of system scheduling is enhanced.

Referring to fig. 5, taking the TDM mode of the LTE system as sa1 as an example, the uplink and downlink subframes of the LTE system are configured as: the uplink and downlink subframe configuration (without bias) of the DSUUDDSUUD, NR system is: DDDSUDDDSU. The TDM pattern of the NR system may be offset in units of subframes, for example, may be shifted forward by 4 subframes with respect to the TDM pattern of the NR system of the LTE system. The uplink and downlink subframes of the NR system after the offset are configured as follows: UDDDSUDDDS.

After the TDM pattern of the NR system is biased, if the sa1 configuration pattern of the LTE system is a special subframe S or an uplink subframe U on a subframe, the NR system is not the special subframe S or the uplink subframe U on the subframe. The terminal device may send uplink signals to the LTE system and the NR system on different subframes according to the uplink and downlink subframe configuration of the LTE system and the TDM pattern of the NR system after the offset. Therefore, in the process that the terminal device needs to perform uplink communication with the LTE system and the NR system, the LTE system may use the TDM mode to configure the uplink and downlink subframes of sa1, which increases the available TDM mode and enhances the flexibility of system scheduling.

With reference to fig. 5, taking the TDM mode of the LTE system as sa4 as an example, the uplink and downlink subframes of the LTE system are configured as: the uplink and downlink subframe configuration (without bias) of the DSUUDDDDDD, NR system is: DDDSUDDDSU.

The uplink and downlink subframes of the NR system after the offset are configured as follows: UDDDSUDDDS.

After the TDM pattern of the NR system is biased, if the sa4 configuration pattern of the LTE system is a special subframe S or an uplink subframe U on a subframe, the NR system is not the special subframe S or the uplink subframe U on the subframe. The terminal device may send uplink signals to the LTE system and the NR system on different subframes according to the uplink and downlink subframe configuration of the LTE system and the TDM pattern of the NR system after the offset. Therefore, in the process that the terminal device needs to perform uplink communication with the LTE system and the NR system, the LTE system may use the TDM mode to configure the uplink and downlink subframes of sa4, which increases the available TDM mode and enhances the flexibility of system scheduling.

It should be understood that, in the embodiment of the present application, when a subframe of the LTE system is a special subframe S or an uplink subframe U, a specific manner in which the NR system is not the special subframe S or the uplink subframe U on the subframe is not limited. For example, the TDM pattern of the LTE system may be biased as shown in fig. 5, the TDM pattern of the NR system may be biased, and cyclic shift biasing may be performed.
