Technical Field

Background

To meet the requirements of people on speed, delay, high-speed mobility, energy efficiency, and diversity and complexity of services in future life, the 3rd Generation Partnership Project (3 GPP) international standards organization began to develop the fifth Generation (5 GPP)^thGeneration, 5G) mobile communication technology.

In 5G systems, a high-Reliable Low latency communication (URLLC) service is introduced, which is characterized by Ultra-high reliability (e.g., 99.999%) transmission within an extreme latency (e.g., 1 ms). To achieve this goal, lower code rate transmissions are introduced to improve the reliability of the transmission.

In addition, considering that enhanced Mobile Broadband (eMBB) traffic and URLLC traffic occur randomly and dynamically, a Modulation and Coding Scheme (MCS) table (table) also needs to be configured dynamically to adapt to the switching of traffic. In the related art, for the URLLC service, a Radio Resource Control (RRC) parameter is introduced to configure a new Radio Network Temporary Identity (RNTI), and if a Cyclic Redundancy Check (CRC) of a Downlink Control Information (DCI) is scrambled by the new RNTI (new RNTI), a Physical Downlink Shared Channel (PDSCH) scheduled by the DCI adopts a new64QAM MCS table under the condition that the new RNTI (RNTI) is configured; if the CRC of the DCI is scrambled by the existing RNTI (existing C-RNTI), the PDSCH scheduled by the DCI adopts the MCS table indicated by the RRC signaling, however, when the MCS table indicated by the RRC signaling is a new64QAM table, the new RNTI and the existing RNTI correspond to the same MCS table, and the function of distinguishing the MCS by the RNTI is lost.

Fig. 2 is a first flowchart illustrating an MCS configuration method according to an embodiment of the present application, as shown in fig. 2, the MCS configuration method includes the following steps:

step 201: the method comprises the steps that terminal equipment receives a first RRC signaling sent by network equipment, wherein the first RRC signaling carries first indication information, and the first indication information is used for indicating the type of an MCS table; wherein, when the first RNTI is configured, the type of the MCS table indicated by the first indication information does not include a first MCS table, and the first MCS table refers to: and when the CRC of the first DCI is scrambled by the first RNTI, the MCS table corresponding to the first DCI.

In the embodiment of the application, the terminal device may be any device capable of communicating with the network device, such as a mobile phone, a notebook, a desktop, a tablet computer, and the like.

In the embodiment of the present application, the network device refers to a base station, for example, a gbb in 5G.

In the embodiment of the present application, the first MCS table refers to: new64QAM MCS table (MCS table with the lowest code rate of 30/1024), the second MCS table is: existing64QAM MCS table (MCS table with the lowest code rate of 120/1024). The first RNTI may be denoted as new RNTI, and the second RNTI may be denoted as existing C-RNTI.

Specifically, when the new RNTI is configured, the base station side avoids configuring the new64QAM MCStable through RRC signaling, and the terminal side does not expect to configure the new64QAM MCS table in RRC signaling. For this reason, the type of the MCS table indicated by the first indication information in the first RRC signaling does not include the first MCS table, i.e., the New64QAM MCStable.

In the embodiment of the present application, the MCS table corresponding to the DCI means: the DCI includes an MCS indication field indicating an index of an MCS used for data scheduled by the DCI, the index being an index of the MCS table.

In a real-time mode, the type of the MCS table that can be indicated by the first indication information if the first RNTI is configured is different from the type of the MCS table that can be indicated by the first indication information if the first RNTI is not configured. For example: the first indication information cannot indicate the first MCS table in case that the first RNTI is configured, and the first indication information can indicate the first MCS table in case that the second RNTI is configured.

Further, the number of types of MCS tables that can be indicated by the first indication information in a case where the first RNTI is configured is smaller than the number of types of MCS tables that can be indicated by the first indication information in a case where the first RNTI is not configured. The method has the advantages of compressing the configuration items of the RRC MCS table, reducing signaling overhead and improving the correctness of RRC signaling detection.

Fig. 3 is a second flowchart illustrating an MCS configuration method according to an embodiment of the present application, where as shown in fig. 3, the MCS configuration method includes the following steps:

step 301: the method comprises the steps that terminal equipment receives a first RRC signaling sent by network equipment, wherein the first RRC signaling carries first indication information, and the first indication information is used for indicating the type of an MCS table; wherein, when the type of the MCS table indicated by the first indication information does not include a first MCS table in a case where a first RNTI is configured, the first RNTI is used to indicate second information including at least one of different information from the first MCS table; and/or when the type of the MCS table indicated by the first indication information includes a first MCS table, the first RNTI is further used for indicating second information, and the second information includes at least one of information different from the first MCS table; the first MCS table refers to: and when the CRC of the first DCI is scrambled by the first RNTI, the MCS table corresponding to the first DCI.

In a real-time mode, when the type of the MCS table indicated by the first indication information does not include the first MCS table, the first RNTI is used to indicate second information, and the second information includes at least one of different information from the first MCS table. In another real-time mode, when the type of the MCS table indicated by the first indication information includes a first MCS table, the first RNTI is further used to indicate second information, and the second information includes at least one of different information from the first MCS table. Here, the second information may be, for example, a service type. Therefore, the use range of the RNTI is expanded, the number of the RNTIs for blind detection is reduced, and the detection effect is improved.

Fig. 4 is a third flowchart illustrating a MCS configuration method according to an embodiment of the present application, where as shown in fig. 4, the MCS configuration method includes the following steps:

step 401: the method comprises the steps that terminal equipment receives a first RRC signaling sent by network equipment, wherein the first RRC signaling carries first indication information, and the first indication information is used for indicating the type of an MCS table; if the type of the MCS table indicated by the first indication information is a first MCS table in the case that the first RNTI is configured, the behavior of the terminal device side is determined by the terminal device, and the first MCS table is: and when the CRC of the first DCI is scrambled by the first RNTI, the MCS table corresponding to the first DCI.

Here, the behavior of the terminal device side is determined by the terminal device, and includes any one of:

1) and after receiving the first RRC signaling, the terminal equipment feeds back a NACK message to a downlink data channel carrying the first RRC signaling.

For example: and after receiving the first RRC signaling, the terminal equipment feeds back a NACK message to a downlink data channel carrying the first RRC signaling if the obtained new64QAM MCS table is obtained.

2) After receiving the first RRC signaling, the terminal equipment analyzes the first MCS table to obtain first MCS configuration and detects a downlink data channel according to the first MCS configuration; and when the terminal equipment detects that the downlink data channel meets the CRC check, the terminal equipment feeds back an ACK message to the downlink data channel carrying the first RRC signaling.

For example: and after receiving the first RRC signaling, the terminal equipment analyzes the MCS configuration according to the new64QAM MCS table.

3) After receiving the first RRC signaling, the terminal equipment analyzes according to a second MCS table to obtain a second MCS configuration, and detects a downlink data channel according to the second MCS configuration; when the terminal equipment detects that the downlink data channel meets CRC check, feeding back an ACK message to the downlink data channel carrying the first RRC signaling; wherein the first MCS table is a new MCS table relative to the second MCS table.

For example: and after receiving the first RRC signaling, the terminal equipment analyzes the MCS configuration according to the existing64QAM MCS table.

4) After receiving the first RRC signaling, the terminal equipment analyzes and obtains a first MCS configuration and a second MCS configuration according to the first MCS table and the second MCS table, and respectively detects a downlink data channel according to the first MCS configuration and the second MCS configuration; and the terminal equipment feeds back an ACK message to the downlink data channel carrying the first RRC signaling when detecting that the downlink data channel meets the CRC check based on any MCS configuration.

For example: after receiving the first RRC signaling, the terminal equipment analyzes two MCS configurations according to a new64QAM MCS table and an existing64QAM MCS table, detects a downlink data channel aiming at the two MCS configurations respectively, and feeds back ACK as long as one detection meets CRC check.

The benefit of this approach is that base station configuration is avoided by unpredictable terminal behavior. Meanwhile, the terminal can be selected simply or an optimization algorithm is realized by the terminal without limiting the terminal behavior.

Fig. 5 is a fourth flowchart illustrating a MCS configuration method according to an embodiment of the present application, where as shown in fig. 5, the MCS configuration method includes the following steps:

step 501: the method comprises the steps that terminal equipment receives a first RRC signaling sent by network equipment, wherein the first RRC signaling carries first indication information, and the first indication information is used for indicating the type of an MCS table; under the condition that the first RNTI is configured, if the type of the MCS table indicated by the first indication information is a first MCS table, the terminal equipment determines that a second DCI corresponds to a second MCS table, the CRC of the second DCI is scrambled by the second RNTI, and the first MCS table refers to: and when the CRC of the first DCI is scrambled by the first RNTI, the MCS table corresponding to the first DCI.

For example: when the new RNTI is configured, if the MCS-table configured in the RRC signaling indicates a new64 QAMZCS table, the terminal still adopts the existing64QAM MCS table for analyzing the PDSCH scheduled by the PDCCH scrambled by the existing C-RNTI.

The advantage of this method is that the behavior of the terminal side is clarified (the MCS is analyzed according to the existing64QAM MCS table), and the detection efficiency of the signaling is improved while the network side RRC is restricted from configuring the new64QAM MCS (the meaning of the new64QAM MCS state is clear).

Fig. 6 is a fifth flowchart illustrating a MCS configuration method according to an embodiment of the present application, where as shown in fig. 6, the MCS configuration method includes the following steps:

step 601: the method comprises the steps that terminal equipment receives a first RRC signaling sent by network equipment, wherein the first RRC signaling carries first indication information, and the first indication information is used for indicating the type of an MCS table; under the condition that the first RNTI is configured, if the type of the MCS table indicated by the first indication information is a first MCS table, the terminal equipment determines that a second DCI corresponds to the first MCS table, the CRC of the second DCI is scrambled by the second RNTI, and the first MCS table refers to: and when the CRC of the first DCI is scrambled by the first RNTI, the MCS table corresponding to the first DCI.

For example: when the new RNTI is configured, if the MCS-table configured in the RRC signaling indicates a new64 QAMMCS table, the terminal still adopts the new64QAM MCS table for resolving the PDSCH scheduled by the PDCCH scrambled by the existing C-RNTI.

The first RNTI is not used to indicate an MCS table in a case where the first RNTI is configured.

The first RNTI is used to indicate second information including at least one of information different from the first MCS table in a case where the first RNTI is configured. For example: the new RNTI may be used for other functional indications by RRC configuration of the new64QAM MCStable. For example, when the new RNTI is configured, if the RRC-configured MCS-table indicates the new64QAM MCS table, the new RNTI is used to configure the traffic type.

In the above scheme, if the new64QAM MCS table is used for the legacy C-RNTI scrambled PDCCH scheduled PDSCH, it may be applicable to all DCI formats and search spaces, or only to a specific search space (e.g., USS), or only to a specific DCI format.
