Abstract

The application discloses a data processing method, network equipment and terminal equipment, which can prevent the network equipment from failing in demodulation because the terminal equipment does not finish 256QAM configuration. The method comprises the following steps: if the network equipment does not receive an indication which indicates that the terminal equipment confirms that the first mapping table is adopted and is sent by the terminal equipment, the network equipment sends an indication comprising a target MCS index to the terminal equipment, wherein the corresponding modulation mode of the target MCS index in the MCS mapping tables which support 256QAM and do not support 256QAM is the same as the TBS index of the transport block size.

Description

Data processing method, network equipment and terminal equipment
Technical Field
The present application relates to the field of communications technologies, and in particular, to a data processing method, a network device, and a terminal device.
Background
The high-order modulation technique is introduced to increase the amount of data to be transmitted without increasing the transmission bandwidth. A typical high-order modulation technique under the Long Term Evolution (LTE) technique is a 64 th order quadrature amplitude modulation (64 QAM) at the highest order. With the development of the technology, the theoretical gain of 256QAM is 33% compared to 64QAM, because each Resource Element (RE) can carry 8-bit data amount in a 256QAM scenario, compared to that each RE can only carry 6-bit data amount in a 64QAM scenario, the data amount that 256QAM can transmit is increased by 33% compared to that of 64QAM in the same RE scenario.
In the third generation partnership project (3 GPP), a Modulation and Coding Scheme (MCS) mapping table is stored on both a network device side and a User Equipment (UE) side, and the MCS mapping table includes: MCS Index, modulation order (modulation order), and transport block size Index (TBS Index). The network equipment side informs the UE by sending the MCS index, so that the UE selects a corresponding modulation order and a transmission block size index in the MCS mapping table according to the MCS index to perform subsequent data processing.
When the UE supports 256QAM, to improve spectrum efficiency, the network device may send an indication to the UE to use an MCS mapping table corresponding to 256QAM, and accordingly, the UE may perform configuration supporting 256QAM and send a message of completing the configuration to the network device. However, after the network device sends an indication that the MCS mapping table corresponding to 256QAM is used to the UE, it takes a period of time for the terminal device to complete configuration of 256QAM, and the network device cannot determine that the UE completes configuration of 256QAM until receiving a message that the configuration sent by the UE is completed.

In one example, referring to fig. 1, the data transmission system includes a terminal device 101, a Radio Access Network (RAN) device 102; in one example, the access network device 102 is a network device in the following embodiments. Wherein, the terminal device 101 and the access network device 102 can be wirelessly connected.
The access network device 102 may be any device with wireless transceiving function, or a chip disposed in a device with wireless transceiving function. The access network equipment 102 includes but is not limited to: a base station (e.g. a base station BS, a base station NodeB, an evolved base station eNodeB or eNB, a base station gdnodeb or gNB in a fifth generation 5G communication system, a base station in a future communication system, an access node in a WiFi system, a wireless relay node, a wireless backhaul node), etc. The base station may be: macro base stations, micro base stations, pico base stations, small stations, relay stations, etc. A network, or future evolution network, in which multiple base stations may support one or more of the technologies mentioned above.

The following description takes the access network device 102 as a base station as an example. The access network devices 102 may be base stations of the same type or different types. The base station may communicate with the terminal apparatus 101, and may also communicate with the terminal apparatus 101 through a relay station. The terminal device 101 may support communication with multiple base stations of different technologies, for example, the terminal device 101 may support communication with a base station supporting an LTE network, may support communication with a base station supporting a 5G network, and may support dual connectivity with a base station of an LTE network and a base station of a 5G network. Such as a RAN node that accesses terminal device 101 to a wireless network. Currently, some examples of RAN nodes are: a gbb, a TRP, an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a Wifi Access Point (AP), etc. In one network configuration, the network device may include CU nodes, or DU) nodes, or RAN devices including CU nodes and DU nodes. The CU and DU are understood to be the division of the access network devices from the logical functional point of view. CUs and DUs may be physically separate or may be deployed together. An access network device may contain one CU and one or more DUs. The CU and DU may be connected via an interface, such as an F1 interface. CUs and DUs may be partitioned according to protocol layers of the wireless network. For example, the CU includes functions of an RRC layer and a PDCP layer, and the DU includes functions of an RLC layer, a MAC layer, and a PHY layer. It is to be understood that the division of CU and DU processing functions according to such protocol layers is merely an example, and may be performed in other manners.

The CU can be further divided into one Control Plane (CU-CP) network element and a plurality of User Plane (CU-User Plane, CU-UP) network elements. Wherein, the CU-CP can be used for control plane management, and the CU-UP can be used for user plane data transmission. The interface between the CU-CP and the CU-UP can be the E1 port.

First, an interaction process between a network device and a terminal device is described, and in some embodiments of the present invention, please refer to fig. 2, a data processing method provided in an embodiment of the present invention may include:
201. the method comprises the steps that network equipment sends a first indication to terminal equipment, wherein the first indication is used for indicating that the terminal equipment adopts a first Modulation Coding Scheme (MCS) mapping table, and the modulation mode which can be supported by the first MCS mapping table is higher than 64 Quadrature Amplitude Modulation (QAM). Correspondingly, a terminal device receives a first indication sent by a network device, where the first indication is used to indicate that the terminal device adopts a first MCS mapping table, and a modulation scheme that can be supported by the first MCS mapping table is higher than 64 QAM.
In this embodiment, before a network device sends a first indication to a terminal device, the first indication is used to indicate that the terminal device adopts a first modulation and coding scheme MCS mapping table, the terminal device may send capability level information to the network device, where the capability level information may indicate that the terminal device supports high-order modulation or low-order modulation, the high-order modulation includes 256 quadrature amplitude modulation QAM, and the low-order modulation may include at least one of 64QAM, 16QAM, and quadrature phase shift keying QPSK, and the network device stores the first MCS mapping table supporting the high-order modulation and a second MCS mapping table supporting the low-order modulation.
In the embodiment of the present application, if the terminal device supports 256QAM, the capability level information indicating that the terminal device supports 256QAM may be sent to the network device, where the capability level information may be sent to the network device at a network access stage of the terminal device, or may be sent to the network device in other processes.
In the embodiment of the application, the network device determines a first MCS mapping table or a second MCS mapping table for communication with the terminal device according to the capability level information sent by the terminal device.
In one embodiment, when the capability level information indicates that the terminal device supports 256QAM, the network device determines the modulation mapping table to be the first MCS mapping table.
In one embodiment, when the capability level information indicates that the user equipment supports 256QAM and a signal to interference plus noise ratio SINR is greater than or equal to an SINR threshold, the network equipment determines to schedule PUSCH using the first MCS mapping table.
In this embodiment of the present application, a network device determines to schedule a PUSCH using the first MCS mapping table, and when a modulation scheme that can be supported by the first MCS mapping table is higher than 64QAM, may send a first indication to a terminal device, where the first indication is used to indicate that the terminal device adopts a first modulation and coding scheme MCS mapping table, and the modulation scheme that can be supported by the first MCS mapping table is higher than 64 QAM.
Correspondingly, the terminal device may receive a first indication sent by the network device, confirm to adopt the first modulation and coding scheme MCS mapping table according to the first indication, and send a second indication to the network device, where the second indication is used to indicate the terminal device to confirm to adopt the first mapping table.
In this embodiment, the terminal device may send PUSCH data to the network device before confirming that the first MCS mapping table is used, and at this time, since the terminal device is PUSCH data generated based on the second MCS mapping table, if the network device demodulates the PUSCH sent by the terminal device based on the first MCS mapping table, a demodulation failure may occur.
202. If the network device does not receive a second indication sent by the terminal device, where the second indication is used to indicate the terminal device to confirm that the first mapping table is adopted, the network device sends a third indication to the terminal device, where the third indication includes a target MCS index, where a modulation manner corresponding to the target MCS index in the first MCS mapping table is the same as a modulation manner corresponding to the target MCS index in the second MCS mapping table, a transport block TBS index corresponding to the target MCS index in the first MCS mapping table is the same as a TBS index corresponding to the target MCS index in the second MCS mapping table, and a modulation manner that the second MCS mapping table can support is not higher than 64 QAM. Correspondingly, the terminal device receives a third indication sent by the network device, where the third indication includes a target MCS index, where a modulation scheme corresponding to the target MCS index in the first MCS mapping table is the same as a modulation scheme corresponding to the target MCS index in the second MCS mapping table, a transport block TBS index corresponding to the target MCS index in the first MCS mapping table is the same as a TBS index corresponding to the target MCS index in the second MCS mapping table, and a modulation scheme that can be supported by the second MCS mapping table is not higher than 64 QAM.
In this embodiment of the application, if the network device does not receive the second indication sent by the terminal device, and the network device receives an indication that the terminal device needs to send data, in the current long term evolution LTE system, the terminal device may estimate channel information used for measuring Channel State Information (CSI), the terminal device calculates, through the estimated channel information, a signal to interference plus noise ratio (SINR) based on an optimal Rank Indication (RI) and/or a Precoding Matrix Indication (PMI), and the terminal device quantizes the calculated SINR to a 4-bit Channel Quality Indication (CQI): and the network equipment distributes MCS indexes to the terminal equipment according to the CQI value reported by the terminal equipment and the network condition. The MCS index may indicate a modulation coding scheme of the current PDSCH coding layer.
In this embodiment of the present application, since the network device does not receive the second indication sent by the terminal device, it cannot determine whether the MCS mapping table adopted by the terminal device at this time is the first MCS mapping table or the second MCS mapping table, and therefore the network device may send a third indication to the terminal device, where the third indication includes the target MCS index.
In this embodiment of the application, a specific implementation of sending, by the network device, the third indication to the terminal device may be:
the network device transmits Downlink Control Information (DCI) through a Physical Downlink Control Channel (PDCCH), and may indicate a target MCS index by using one bit in the DCI, or may add 1 bit in the DCI to indicate the terminal device to use the target MCS index. For example, for DCI format 1(DCI format1), DCI format1A (DCI format1A), 1 bit may be added in the TPC command for PUCCH field (field); alternatively, for DCI format 2(DCI format2), 1 bit may be added in the redundancy version field. Wherein the TPC is Transmit Power Control (TPC).
In this embodiment of the present application, a modulation scheme corresponding to the target MCS index in the first MCS mapping table is the same as a modulation scheme corresponding to the target MCS index in the second MCS mapping table, and a transport block TBS index corresponding to the target MCS index in the first MCS mapping table is the same as a TBS index corresponding to the target MCS index in the second MCS mapping table. That is, the modulation scheme corresponding to the target MCS index in the MCS mapping table supporting 256QAM is the same as the modulation scheme corresponding to the MCS mapping table not supporting 256QAM, and the transport block TBS index corresponding to the target MCS index in the MCS mapping table supporting 256QAM is the same as the TBS index corresponding to the MCS mapping table not supporting 256 QAM.
In the embodiment of the present application, the MCS mapping table defined by the existing standard includes: MCS index, modulation order and TBS index.
In one embodiment, the target MCS index is 0, and the corresponding modulation order and TBS index are consistent when only MCS is 0 in the first MCS mapping table and the second MCS mapping table defined by the existing protocol. The network equipment receives PUSCH data sent by the terminal equipment; the network device may demodulate the PUSCH data based on the target MCS index. Therefore, regardless of whether the MCS mapping table employed by the terminal device is the first MCS mapping table or the second MCS mapping table, the terminal device and the network device can modulate and demodulate PUSCH data based on the same modulation order and TBS index.
The application provides a data processing method, which comprises the following steps: the method comprises the steps that network equipment sends a first indication to terminal equipment, wherein the first indication is used for indicating that the terminal equipment adopts a first Modulation Coding Scheme (MCS) mapping table, and the modulation mode which can be supported by the first MCS mapping table is higher than 64 Quadrature Amplitude Modulation (QAM); if the network device does not receive a second indication sent by the terminal device, where the second indication is used to indicate the terminal device to confirm that the first mapping table is adopted, the network device sends a third indication to the terminal device, where the third indication includes a target MCS index, where a modulation manner corresponding to the target MCS index in the first MCS mapping table is the same as a modulation manner corresponding to the target MCS index in the second MCS mapping table, a transport block TBS index corresponding to the target MCS index in the first MCS mapping table is the same as a TBS index corresponding to the target MCS index in the second MCS mapping table, and a modulation manner that the second MCS mapping table can support is not higher than 64 QAM. Through the above manner, the network device issues the indication of adopting the first modulation coding scheme MCS mapping table to the terminal device, and before the network device confirms that the terminal device has adopted the first mapping table, the terminal device schedules the PUSCH by using the target MCS index, and the terminal device sends the PUSCH to the network device based on the target MCS index regardless of whether the terminal device has completed 256QAM configuration or has not completed 256QAM configuration, and accordingly, the network device demodulates the PUSCH based on the target MCS index, and since the target MCS index is the same as the TBS index in the corresponding modulation order and modulation order in the MCS mapping table whose supported modulation mode is not higher than 64QAM and the corresponding modulation order in the MCS mapping table whose supported modulation mode is higher than 64QAM, the network device does not fail to decode.
In some embodiments of the present invention, please refer to fig. 3, a data processing method according to an embodiment of the present invention may include:
301. the network equipment sends a fourth indication to the terminal equipment, wherein the fourth indication is used for indicating the terminal equipment to adopt a second Modulation Coding Scheme (MCS) mapping table, and the modulation mode which can be supported by the second MCS mapping table is not higher than 64 Quadrature Amplitude Modulation (QAM). Correspondingly, the terminal device receives a fourth indication sent by the network device, where the fourth indication is used to indicate that the terminal device adopts a second Modulation and Coding Scheme (MCS) mapping table, and a modulation scheme that can be supported by the second MCS mapping table is not higher than 64 QAM.
In this embodiment of the present application, in one scenario, if a network device needs to change from a modulation and demodulation scheme based on 256QAM to a modulation and demodulation scheme based on less than 256QAM, a fourth indication needs to be sent to a terminal device, where the fourth indication is used to indicate that the terminal device adopts a second modulation and coding scheme MCS mapping table, and a modulation scheme that can be supported by the second MCS mapping table is not higher than 64 QAM.
Correspondingly, the terminal device may receive a fourth indication sent by the network device, where the fourth indication is used to indicate that the terminal device adopts a second modulation and coding scheme, MCS, mapping table, and a modulation scheme that can be supported by the second MCS mapping table is not higher than 64 QAM.
In this embodiment, the terminal device may send PUSCH data to the network device before confirming that the second MCS mapping table is used, and at this time, since the terminal device is the PUSCH data generated based on the first MCS mapping table, if the network device demodulates the PUSCH sent by the terminal device based on the second MCS mapping table, a demodulation failure may occur.
302. If the network device does not receive a fifth indication sent by the terminal device, where the fifth indication is used to indicate that the terminal device confirms to adopt the second mapping table, the network device sends a sixth indication to the terminal device, where the sixth indication includes a target MCS index, where a modulation manner of the target MCS index in a first MCS mapping table is the same as a modulation manner of the target MCS index in a second MCS mapping table, a TBS index of the target MCS index in the first MCS mapping table is the same as a TBS index in the second MCS mapping table, and a modulation manner that the first MCS mapping table can support is higher than 64 QAM. Correspondingly, the terminal device receives a sixth indication sent by the network device, where the sixth indication includes a target MCS index, where a modulation scheme corresponding to the target MCS index in the first MCS mapping table is the same as a modulation scheme corresponding to the target MCS index in the second MCS mapping table, a TBS index corresponding to the target MCS index in the first MCS mapping table is the same as a TBS index corresponding to the target MCS index in the second MCS mapping table, and a modulation scheme that can be supported by the first MCS mapping table is higher than 64 QAM.
In this embodiment of the application, if the network device does not receive the fifth indication sent by the terminal device, and the network device receives an indication that the terminal device needs to send data, in the current long term evolution LTE system, the terminal device may estimate channel information used for measuring Channel State Information (CSI), the terminal device calculates, according to the estimated channel information, a signal to interference plus noise ratio (SINR) based on an optimal Rank Indication (RI) and/or a Precoding Matrix Indication (PMI), and the terminal device quantizes the calculated SINR to a 4-bit Channel Quality Indication (CQI): and the network equipment distributes MCS indexes to the terminal equipment according to the CQI value reported by the terminal equipment and the network condition. The MCS index may indicate a modulation coding scheme of the current PDSCH coding layer.
In this embodiment of the present application, since the network device does not receive the fifth indication sent by the terminal device, it cannot determine whether the MCS mapping table adopted by the terminal device at this time is the first MCS mapping table or the second MCS mapping table, and therefore the network device may send a sixth indication to the terminal device, where the sixth indication includes the target MCS index.
In this embodiment of the application, a specific implementation that the network device sends the sixth indication to the terminal device may be:
the network device transmits Downlink Control Information (DCI) through a Physical Downlink Control Channel (PDCCH), and may indicate a target MCS index by using one bit in the DCI, or may add 1 bit in the DCI to indicate the terminal device to use the target MCS index. For example, for DCI format 1(DCI format1), DCI format1A (DCI format1A), 1 bit may be added in the TPC command for PUCCH field (field); alternatively, for DCI format 2(DCI format2), 1 bit may be added in the redundancy version field. Wherein the TPC is Transmit Power Control (TPC).
In this embodiment of the present application, a modulation scheme corresponding to the target MCS index in the first MCS mapping table is the same as a modulation scheme corresponding to the target MCS index in the second MCS mapping table, and a transport block TBS index corresponding to the target MCS index in the first MCS mapping table is the same as a TBS index corresponding to the target MCS index in the second MCS mapping table. That is, the modulation scheme corresponding to the target MCS index in the MCS mapping table supporting 256QAM is the same as the modulation scheme corresponding to the MCS mapping table not supporting 256QAM, and the transport block TBS index corresponding to the target MCS index in the MCS mapping table supporting 256QAM is the same as the TBS index corresponding to the MCS mapping table not supporting 256 QAM.
In the embodiment of the present application, the MCS mapping table defined by the existing standard includes: MCS index, modulation order and TBS index.
In one embodiment, the target MCS index is 0, and the corresponding modulation order and TBS index are consistent when only MCS is 0 in the first MCS mapping table and the second MCS mapping table defined by the existing protocol. The network equipment receives PUSCH data sent by the terminal equipment; the network device may demodulate the PUSCH data based on the target MCS index.
