Abstract

The method comprises: adding one piece of indication information at a first network device side to indicate those time units capable of being used for uplink sending in time units that are caused by a reference uplink and downlink configuration to be incapable of uplink sending; and a terminal device being capable of sending a PUSCH/PRACH/SRS on these time units, but being incapable of sending a PUCCH.

Description

Method and device for information notification

Technical field

The present invention relates to the field of mobile communications, and in particular, to a method and device for information notification.

Background technique

In a Long Term Evolution (LTE) system, a terminal device supports simultaneous access to two network devices. This access method is called Dual Connectivity (DC). One of the network devices is the main network device. The other network device is a secondary network device. During the development and evolution of wireless communication systems, operators will deploy 5G New Interface (NR) systems and Long Term Evolution (LTE) systems at the same time. Terminal equipment also supports simultaneous access to LTE network equipment and NR network equipment, because LTE is also called Evolved Universal Terrestrial Radio Access (Evolved Universal Terrestrial Radio Access, E-UTRA), so this access method is called Evolved Universal Terrestrial Wireless Access and New Air interface dual connection (E-UTRA, NR, Dual Connectivity, EN-DC). In the EN-DC mode, LTE network equipment is the main network equipment, and NR network equipment is the secondary network equipment. Of course, with the evolution of the system, the new air interface and the evolved universal land-surface wireless access dual connection can also be supported in the future ( NR (E-UTRA Dual Connectivity, NE-DC), that is, the network equipment of NR is the main network equipment, and the network equipment of LTE is the auxiliary network equipment.

For wireless communication systems, they can be divided into Frequency Division Duplex (FDD) mode and Time Division Duplex (TDD) mode according to the different duplex modes. Among them, wireless operating in TDD mode Communication system, the system usually contains only one working frequency band, so this frequency band is also called unpaired frequency band. For systems using unpaired frequency bands, the entire working frequency band is only used for downlink communication or only for uplink communication in the area covered by the same network device for a period of time; for wireless communication systems operating in FDD mode, the system Usually contains two pairs of frequency bands for communication, one of which is used for downlink communication from the network device to the terminal device, and the other is used for uplink communication from the terminal device to the network device.

At present, a typical deployment method is that NR is deployed in unpaired frequency bands using the TDD mode, such as a frequency band near 3.5GHz, and LTE is deployed in paired frequency bands, such as a frequency band near 1.8GHz. In this deployment scenario, terminal equipment working in EN-DC mode works in FDD mode on the LTE side, and works in TDD mode on the NR side.

In order to avoid the impact of cross-modulation on performance, and at the same time limited by the terminal's capabilities and transmit power, for terminals operating under EN-DC, they only send uplink signals at one frequency point at the same time, that is, when When a terminal sends an uplink signal on NR, the terminal does not send an uplink signal on LTE, and vice versa.

In order to realize that the terminal equipment sends only one uplink in NR and LTE, the LTE network equipment configures the terminals working in DC mode with the same reference uplink and downlink configuration in the case of TDD-FDD carrier aggregation and TDD carrier as the main carrier, as follows Table 1 shows. The network device may configure the terminal with one of the seven configurations in Table 1, so that the terminal device sends an uplink signal only on a part of the LTE uplink subframe. For example, when the terminal is configured with reference uplink and downlink configuration 0, the terminal device can only send uplink signals on subframes 2, 3, 4, 7, 8, and 9. The uplink signals include PUCCH (Physical-layer uplink control channel, physical Uplink control channel), or PUSCH (Physical-layer shared channel), or PRACH (Physical-layer random access channel), or SRS (Sounding reference signal) At the same time, the terminal device cannot send any uplink signals on the sub-frames 0, 1, 5, and 6 (that is, the sub-frames marked with "-" in the table). At the same time, the network device can also configure an offset value for the terminal. The value of this offset value ranges from 0 to 9 and is used to adjust the number of uplink subframes that the terminal device can use. For example, when the terminal device is configured with reference uplink and downlink configuration 1, the original terminal device can only send uplink signals on subframes 2, 3, 7, and 8. If the terminal device is also configured with an offset value, such as 2 , Then the subframes in which the terminal sends uplink signals become subframes 4, 5, 9, and 0.

Table 1

In the prior art, once a terminal device is configured with one of the uplink and downlink configurations in the above table, the terminal device can only send a PUCCH on the uplink subframe corresponding to the uplink and downlink configuration, and for other uplink signals including PUSCH and PRACH With SRS, the terminal device can also only send in the uplink subframe in which the PUCCH is sent.

According to the configuration in the above table, at least 4 of the 10 subframes cannot be used for uplink transmission on the LTE side of the terminal. For subframes on the LTE side that are not configured to send uplink signals, the terminal on the NR side does not necessarily send uplink signals within the time period corresponding to these subframes, which will cause the terminal to waste uplink resources on the LTE side and reduce the network. Spectrum utilization. As shown in Figure 1, the correspondence between LTE and NR subframes, where "U" represents uplink, "D" represents downlink, and "X" represents a subframe that cannot be used for communication. The terminal uses a 15kHz subcarrier interval on the LTE side. The 30kHz subcarrier interval is used on the NR side. It can be seen that the NR side only performs downlink reception in the time period corresponding to the LTE subframe included in the box, so LTE should have been able to perform uplink transmission in this subframe, but Due to the limitation of the reference uplink and downlink configuration in the prior art, the terminal cannot send an uplink signal on the subframe, resulting in a waste of resources.

It can be seen that, for a terminal working in the EN-DC mode, the uplink and downlink configuration with reference to the uplink and single transmission is used to implement resource allocation of uplink information on the LTE side with insufficient flexibility.

The embodiments of the present invention describe various embodiments in combination with an access network device and a terminal device, where:

Terminal equipment can also be called user equipment (User Equipment, UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user Agent or user device. The terminal device can be a station (STAION, ST) in the WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, and personal digital processing (Personal Digital Assistant, PDA) devices, handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, and next-generation communication systems, such as fifth-generation communications (fifth- terminal equipment in a generation (5G) network, or terminal equipment in a public land mobile network (PLMN) network that will evolve in the future.

By way of example and not limitation, in this embodiment of the present invention, the terminal device may also be a wearable device. Wearable devices can also be referred to as wearable smart devices. They are the general name for applying wearable technology to intelligently design daily wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. A wearable device is a device that is worn directly on the body or is integrated into the user's clothing or accessories. Wearable devices are not only a hardware device, but also powerful functions through software support, data interaction, and cloud interaction. Broad-spectrum wearable smart devices include full-featured, large-sized, full or partial functions that do not rely on smart phones, such as smart watches or smart glasses, and only focus on certain types of application functions, and need to cooperate with other devices such as smart phones Use, such as smart bracelets, smart jewelry, etc. for physical signs monitoring.

Here, the small cell can include: urban cell, micro cell, pico cell (Pico cells), femto cells (Femto cells), etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

In addition, multiple carriers on the carrier in the LTE system or 5G system can work on the same frequency at the same time. In some special scenarios, the above carrier and cell concepts can be considered equivalent.

In this case, it can be considered that the concept of a carrier is the same as a cell. For example, a UE accessing a carrier and accessing a cell are equivalent.

In the embodiment of the present invention, the frequency domain resources used by the network device and the terminal device for wireless communication (for example, uplink transmission or downlink transmission) are frequency domain resources used based on a competition mechanism.

For example, the network device and / or the terminal device may detect whether a frequency domain resource with a certain bandwidth (for example, 20 MHz) is currently in an idle state, or whether the frequency domain resource is used by other devices.

If the frequency domain resource is in an idle state, or the frequency domain resource is not used by other devices, the network device and / or the terminal device can use the frequency domain resource for communication, for example, uplink transmission or downlink transmission.

If the frequency domain resource is not in an idle state, or the frequency domain resource is already used by another device, the network device and / or the terminal device cannot use the frequency domain resource.

It should be noted that, in the embodiment of the present invention, the specific method and process of the foregoing competition mechanism may be similar to the prior art. Here, in order to avoid redundant description, detailed descriptions thereof are omitted.

The time unit in the embodiment of the present invention may be a subframe, a time slot, a micro time slot, a symbol, or the like. It should be noted that different wireless communication systems have different definitions of subframes and time slots. The time unit here may be an LTE subframe, time slot, sub-slot, symbol, or It is the subframe, time slot, micro time slot, and symbol of the NR system.

It should be understood that in the embodiments of the present invention, "when", "if" and "if" all mean that the terminal device or the access network device will make corresponding processing under certain objective conditions, and is not a limited time, and Nor does it require terminal equipment or access network equipment to implement a judgment action, nor does it mean that there are other restrictions.

The wireless communication system includes network equipment and terminal equipment. There is downlink data transmission and uplink data transmission between the network equipment and the terminal equipment, and the network equipment can communicate with multiple terminal equipment. The terminal device works in the dual connection mode of LTE and NR, that is, the terminal device accesses both the LTE network device and the NR network device at the same time. Network equipment includes LTE network equipment and NR network equipment. As shown in FIG. 2a, in one implementation, a network device of LTE and a network device of NR can be deployed on the same site. When the LTE network equipment and the NR network equipment are deployed at the same site, the LTE network equipment and the NR network equipment can share the same set of hardware devices, or they can use different hardware devices. As shown in FIG. 3a, in another implementation manner, the LTE network device and the NR network device may also be deployed at different sites.

The network device sends information to the terminal device through the forward link (also known as the downlink) and receives information from the terminal device through the reverse link (also known as the uplink). For example, in a Frequency Division Division (FDD) system, the forward link may use a different frequency band from the reverse link. As another example, in a Time Division Duplex (TDD) system and a Full Duplex (TDD) system, the forward link and the reverse link may use a common frequency band.

At a given time, the network device or terminal device may be a wireless communication transmitting device and / or a wireless communication receiving device. When transmitting data, the wireless communication transmitting device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (for example, generate, receive from another communication device, or save in a memory, etc.) a certain number of data bits to be transmitted to the wireless communication receiving device through a channel. Such data bits may be included in a transport block (or transport blocks) of data, which may be segmented to generate a plurality of code blocks.

Alternatively, the second time unit indicated by the second indication information is at least one of the time units without padding, but the second time unit indicated by the second indication information does not include the time unit in the first time unit. In this way, the second indication information configures a time unit in the first indication information that is not configured to send at least one signal of PUSCH, PRACH, or SRS, and is configured to be able to send at least one of PUSCH, PRACH, or SRS. Signal, but the second time unit is not used to send PUCCH.

The execution sequence of steps S401 and S402 may be arbitrary, or may be performed simultaneously.

S403: The first network device sends the first instruction information and the second instruction information to the terminal device, and the terminal device receives the first instruction information and the second instruction information.

The first indication information and the second indication information may be sent in one message or may be sent in two pieces of information.

Optionally, the first indication information and the second indication information may be carried in the terminal-specific configuration information and sent by the first network device to the terminal device.

S404: The terminal device determines a time unit for transmitting at least one signal of PUSCH, PRACH, or SRS according to the second indication information.

In one embodiment, the terminal device determines a second time unit according to the second indication information, and the second time unit is a time unit used by the terminal device to send at least one signal of PUSCH, PRACH, or SRS.

Optionally, the terminal device may jointly determine a time unit capable of transmitting at least one signal of PUSCH, PRACH, or SRS according to the first indication information and the second indication information.

In one embodiment, the terminal device jointly determines, according to the first indication information and the second indication information, that a time unit capable of sending at least one signal of PUSCH, PRACH, or SRS is a union of the first time unit and the second time unit. For example, if the first time unit is sub-frame A, sub-frame B, and sub-frame C, and the second time unit is sub-frame C and sub-frame D, the terminal device determines at least one signal capable of sending PUSCH, PRACH, or SRS as Sub-frame A, sub-frame B, sub-frame C, and sub-frame D.

S405: The terminal device determines a time unit for sending a PUCCH according to the first instruction information.

The execution order of steps S404 and S405 may be arbitrary, or may be performed simultaneously.

In one embodiment, the time domain unit is a frame, and the time unit is a subframe.

In order to improve the utilization rate of the uplink resources of the terminal working in the EN-DC mode on the LTE side, the embodiment of the present invention adds an indication information on the LTE side to indicate that those subframes that are referenced for uplink and downlink configuration and cannot be sent in uplink can The subframes used for uplink transmission enable the terminal to send PUSCH / PRACH / SRS on these subframes, but cannot send PUCCH.

In the embodiment of the present invention, because an indication information is added to the first network device to indicate those time units that can be used for uplink transmission among the referenced time units that are configured to be unable to be transmitted upstream, so that the terminal can operate on these time units. Send PUSCH / PRACH / SRS, but not PUCCH. The terminal device working in the EN-DC mode can have more uplink subframes on the first network device side, which can improve the spectral efficiency of uplink transmission compared to the prior art.

Further, in the above method, the terminal device cannot send an uplink signal in a time unit other than the first time unit and the second time unit in the time domain unit.

The specific form of the second indication information in the foregoing embodiment may be in one of the following ways.

In one embodiment, the second indication information includes a field of N bits, where N is a positive integer greater than or equal to 1. Each bit corresponds to a time unit. When the bit is the first state value, it indicates that the corresponding time unit can send a PUSCH At least one of the PRACH or SRS signals, when the bit is the second state value, it means that the corresponding time unit cannot send at least one of the PUSCH, PRACH or SRS signals.

In an implementation manner, the N is equal to the number of time units included in the time domain unit, and the N-bit field has a one-to-one correspondence with the time units included in the time domain unit.

For example, the first indication information is a field including 10 bits, and each bit of the field corresponds to a subframe in a frame. Optionally, the i-th bit corresponds to a subframe numbered (i-1), where the value of i is a positive integer from 1 to 10. For example, when the value of the i-th bit is 0, it indicates that the subframe (i-1) is a subframe that cannot send uplink signals, and when the value of the i-th bit is 1, it indicates that the subframe (i-1) is capable of sending uplink signals. The sub-frames can of course also be reversed.

In this manner, the terminal device may directly determine a time unit capable of transmitting at least one signal of PUSCH, PRACH, or SRS according to the second indication information.

Through the configuration of this implementation manner, independent configuration can be performed for any time unit in the time domain unit, and configuration flexibility is ensured to the greatest extent.

In another implementation manner, the N is equal to the number of time units included in the time domain unit minus the number of time units included in the first time unit; the N-bit field and the time domain unit are divided by the first Time units other than one time unit correspond one-to-one.

For example, for at least one of the configurations 0 to 6, the value of N is equal to the number of subframes in the configuration that cannot be used to send uplink signals. Exemplarily, when the first indication information indicates configuration 0, the value of N is equal to 4; when the first indication information indicates configuration 1, the value of N is equal to 6; when the first indication information indicates configuration 2, the value of N is The value is equal to 8; when the first indication indicates configuration 3, the value of N is 7; when the first indication indicates configuration 4, the value of N is equal to 8; when the first indication indicates configuration 5, N The value of is equal to 9; when the first indication information indicates configuration 6, the value of N is equal to 5.

In this manner, the terminal device may jointly determine a time unit capable of transmitting at least one signal of PUSCH, PRACH, or SRS according to the first indication information and the second indication information.

With the configuration of this implementation manner, the signaling overhead of the second indication information can be reduced while ensuring the flexibility of the time unit configuration.

In another embodiment, the second indication information is a field capable of indicating M different states, and M is a positive integer greater than or equal to 1, where M is equal to the time domain unit except the first time unit. The number of time units other than the time unit combination available for transmitting at least one signal of PUSCH, PRACH, or SRS.

One of the M states in this field corresponds to a subframe configuration.

For example, the value of M is 4, when the first indication information indicates configuration 0, the four states indicated by the second indication information correspond to the subframe states shown in FIGS. 6a-6f, as shown in FIG. 6a, which are marked as The sub-frames of "X" and "Y" are sub-frames whose second indication information is configured to be unable to transmit uplink signals, and those marked with "Y" are configured to be capable of transmitting uplink signals (including PUSCH, PRACH, or SRS) through the first indication information At least one of the signals). In addition, when the network device does not send the first instruction information to the terminal device, the terminal device determines, according to the configuration indicated by the second instruction information, a subframe that can send an uplink signal and / or a subframe that cannot send an uplink signal. When the second instruction information indicates configuration 1, two of the four states indicated by the first instruction information are available, as shown in FIG. 6b. When the second instruction information indicates the configuration 2, any one of the four states indicated by the first instruction information indicates the subframe configuration shown in FIG. 6c. When the first instruction information indicates configuration 3, two of the four states indicated by the second instruction information are available, as shown in FIG. 6d. When the first instruction information indicates the configuration 4, any one of the four states indicated by the second instruction information indicates the subframe configuration shown in FIG. 6e. When the first instruction information indicates configuration 5, any one of the four states indicated by the second instruction information indicates the subframe configuration shown in FIG. 6f.

It should be noted that when the number of states that the second instruction information can take is more than the number of available time unit configurations, the method described above can be used, and only some of the states in the second instruction information can be used to indicate the time unit configuration. Whereas the remaining state is a reserved state, multiple states in the second instruction information may also correspond to a time unit configuration, which is not limited in this embodiment.

With the configuration of this implementation manner, it is possible to achieve a compromise between the flexibility of the configuration of the time unit and the signaling overhead of the second indication information.

In another embodiment, the first indication information is a field capable of indicating two different states.

Based on the previous embodiment, the second indication information needs to indicate at most 4 states, that is, a 2-bit indication field is required for indication. In order to reduce the overhead of the indication field, in this embodiment, only state 0 and state 1 in FIG. 6a are retained, and the second indication information only needs to indicate one of state 0 and state 1. For example, specifically, when the first indication information indicates the configuration 0, the second indication information indicates the configuration of the subframe corresponding to the state 0 or the state 1 in FIG. 6a. When the first indication information indicates the configuration 1, the second indication information indicates the configuration of the subframe corresponding to the state 0 or the state 1 in FIG. 6b. When the first indication information indicates the configuration 2, the second indication information indicates the subframe configuration in FIG. 5c. When the first instruction information indicates the configuration 2, any one of the two states indicated by the second instruction information indicates the subframe configuration shown in FIG. 6c. When the first instruction information indicates the configuration 3, the two states of the second instruction information correspond to the state 0 and the state 1 in FIG. 6d, respectively. When the first instruction information indicates configuration 4, any one of the two states indicated by the second instruction information indicates the subframe configuration shown in FIG. 6e. When the first instruction information indicates the configuration 5, any one of the two states indicated by the second instruction information indicates the subframe configuration shown in FIG. 6f.

With this implementation manner, the signaling overhead of the second indication information can be reduced to the maximum.
