Description

Terminal configuration method, terminal and base station

Technical Field

The invention relates to the technical field of mobile communication, in particular to a terminal configuration method, a terminal and a base station.

Background

In the prior art, each Bandwidth Part (BWP) of the serving cell may configure a Semi-Persistent Scheduling (SPS) configuration. Since one serving cell may configure multiple BWPs, one serving cell may configure multiple SPS configurations, which are typically used to configure terminal downlink resources. Since only one BWP will be activated for a serving cell at the same time, there is actually only one SPS configuration activated at a time. Similarly, a Type2 configuration grant (Type2CG) is typically used to configure the uplink resources of the terminal, and each BWP may configure a CG configuration. Therefore, when a Medium Access Control (MAC) entity receives an activation message (deactivation message) of SPS or Type2CG transmitted through a Physical Downlink Control Channel (PDCCH), the MAC entity can know exactly which set of SPS/CG configuration is activated (deactivated).

In an Industrial Internet of Things (IIoT) scene, one BWP configuration is supported, and a plurality of sets of SPS or CG configurations are activated to adapt to the requirement of Time Sensitive Communication (TSC) service, and meanwhile, the problem that the SPS period and the TSC service period cannot be completely matched is solved by supporting a plurality of configurations. Therefore, there is a need for a method that enables flexible SPS/CG configuration in scenarios such as IIoT.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a User terminal or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network device 12 may be a Base Station and/or a core network element, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention only takes the Base Station in the NR system as an example, but does not limit the specific type of base station.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

Currently, activation/deactivation of SPS/CG configuration is generally performed through Downlink Control Information (DCI). In IIoT scenarios, the prior art generally has the following problems:

1) one or N of the plurality of SPS/CG configurations cannot be individually activated/deactivated (N is an integer greater than 1). In addition, the activation indication refers to ambiguity, and meanwhile, if a plurality of SPS/CG configurations are activated in an existing manner of individually activating each SPS/CG configuration, a large time delay is caused, and transmitting a plurality of DCIs also increases the error probability, and may not meet the time delay requirement, the reliability requirement, and the like of the IIoT scenario.

2) In the IIoT scenario, a terminal (UE) may repeat the same behavior thousands of times, and the UE activity range is limited, and the behavior pattern of the UE may be predictable within a certain time, such as using the same period, transport block size (TB size), or modulation and demodulation scheme. In a scenario where reliability is enhanced by multiple SPS/CG configurations, some configurations may be constant, and thus, if multiple SPS/CG configurations are configured in the existing configuration manner, RRC signaling overhead may be large due to coverage of too many repeated or useless information.

Therefore, how to clearly indicate the activated/deactivated SPS configuration or Type2CG configuration, and how to effectively save the overhead of configuration signaling/the overhead of activation signaling in multiple traffic flows, and reduce the activation delay are problems to be solved by the present application.

To solve one or more of the above problems, embodiments of the present invention provide a terminal configuration method, which may implement flexible SPS/CG configuration. Referring to fig. 2, when the terminal configuration method provided in the embodiment of the present invention is applied to a network device, such as a base station, the method includes:

step 21, sending a first configuration message to the terminal, where the first configuration message includes at least one of the following: at least one SPS/CG configuration activated; deactivated at least one SPS/CG configuration; at least one SPS/CG configuration suspended and its suspension time.

Here, the specific SPS/CG configuration included in the first configuration message may be indicated by an index or an identifier of the SPS/CG configuration. Additionally, the SPS/CG configuration described herein is either an SPS configuration or a CG configuration.

Through the steps, the embodiment of the invention can activate/deactivate/suspend one or more SPS/CG configurations through the first configuration message, thus, the activation/deactivation/suspension of the SPS/CG configurations can be realized through one message, the number of configuration messages is reduced, the signaling overhead and the configuration time delay are reduced, and the configuration reliability is improved.

In the IIoT scenario, the terminal may repeat the same behavior thousands of times, the activity range of the terminal is limited, and the behavior pattern of the terminal may be predictable within a certain time, so that the SPS/CG configuration serving a certain type of service may have more of the same parameters. In accordance with at least one embodiment of the present invention, the SPS/CG configuration is optimized for the above features, and is divided into two parts.

Specifically, each SPS configuration may include a common configuration parameter and a dedicated additional configuration parameter. The common configuration parameter of the SPS configuration is a configuration parameter shared by all SPS configurations, and may specifically include one or more of a period, a transport block size, and a modulation and demodulation scheme. The additional configuration parameters are configuration parameters specific to each SPS configuration, and of course, the additional configuration parameters of any two SPS configurations may be completely different, partially identical or completely identical. Specifically, the additional configuration parameters of the SPS configuration may include an offset of the video resource, and the like. Similarly, the CG configurations may be divided into a common configuration parameter shared by all CG configurations and additional configuration parameters dedicated to each CG configuration.

In addition, embodiments of the present invention may refer to each SPS/CG configuration with an index or Identification (ID) of the SPS/CG configuration. For example, for SPS configuration 1, two parts contain a Common configuration parameter (Common configuration) and an additional configuration parameter (Delta configuration) for SPS configuration 1. Different configured indices/IDs may be indexed or indicated for each set of SPS configurations.

Alternatively, the common configuration parameter and each additional configuration parameter may be predefined and pre-stored at the network device and the terminal side. For example, the device is stored in the storage hardware of the device before shipment.

As another implementation manner, the common configuration parameter and each additional configuration parameter may also be configured by the network device to the terminal in advance, for example, after the terminal initially accesses the network, the common configuration parameter and each additional configuration parameter supported by the network are sent to the terminal through a signaling message.

As yet another implementation, the network device may send only the common configuration parameters and the additional configuration parameters supported by the terminal to the terminal, which may reduce the signaling overhead required for configuration. At this time, before sending the first configuration message in step 21, the network device may further send a second configuration message to the terminal, where the second configuration message includes common configuration parameters shared by each SPS/CG configuration; and sending a third configuration message to the terminal according to the SPS/CG configuration supported by the terminal, wherein the third configuration message comprises additional configuration parameters special for each SPS/CG configuration supported by the terminal; wherein the configuration parameters of each SPS/CG configuration comprise the common configuration parameters and additional configuration parameters special for the SPS/CG configuration. Of course, in the embodiment of the present invention, the network device may also send the common configuration parameter of the SPS/CG configuration and the additional configuration parameter dedicated to each SPS/CG configuration supported by the terminal to the terminal through one configuration message.

Table 1 provides a specific example of an SPS configuration:

TABLE 1

Wherein the Common configuration part may mainly comprise parameters such as period, TB size or modulation and demodulation mode. The Delta configuration includes the remainder of the SPS configuration, except for the common configuration parameters.

The network device may issue a Common configuration parameter (Common configuration) when the terminal initially accesses, the terminal performs a preliminary configuration according to the Common configuration parameter, and then the network device issues one or more additional configuration parameters (Delta configuration) configured by the SPS through a dedicated signaling according to different service requirements.

For example, the network supports 16 SPS configurations in total, that is, 16 Delta configurations. For the UE1, the Delta configuration index corresponding to multiple services is 1-5, and the network equipment can only send the Delta configuration of SPS configuration 1-5 to the UE 1.

According to at least one embodiment of the present invention, the first configuration message in step 21 has various forms, for example, DCI, MAC CE, RRC message, or the like may be used. The following description is made in detail, and it should be noted that the structures/compositions of the following messages are only an example that can be adopted by the embodiments of the present invention, and are not used to limit the present invention.

A) The first configuration message is downlink control information DCI, where the DCI includes:

For example, the following fields may be added to DCI:

1. an activation indication field identifier for activation, the length of which is 1bit, and when the bit is set to 0, the activation is configured for SPS or CG;

2. and activating an activation configuration index field with a length of 8-32 bits, wherein the specific number of bits is consistent with the configuration number of the SPS or the CG. When the nth bit value of the field is 1, the nth SPS or CG configuration is activated.

3. A deactivation indication field identifier for deactivation, the length of which is 1bit, and the bit is set to 1, which indicates that the SPS or CG configuration is deactivated;

4. deactivating a configuration index field, deactivating configuration indexes, wherein the length of the configuration index field is 8-32 bits, and the specific bit number is consistent with the configuration number of the SPS or the CG. And when the nth bit value of the field is 1, the nth SPS or CG configuration is deactivated.

5. And a Suspend indication field (Suspend indication field) with the length of 1bit and the bit of 1, which is used for indicating that the subsequent bit is Suspend-related operation.

Suspend Index and timer field are used for suspending execution of partial configuration, the suspend Index being in the Index containing the suspended SPS or CG. When the nth bit value of the domain is 1, showing the nth SPS or CG configuration of suspend; in addition, a corresponding suspend timer is also included. Here, the number of bits occupied by the timer is related to the maximum timer supported by the system. The suspend Index field has n 1 fields and n timer fields.

Of course, the embodiment of the present invention may also design a new DCI, such as DCI format 2_2, which only includes the above fields, and thus may be specifically used for SPS/CG activation, deactivation, and suspend.

B) The first configuration message is a MAC CE, and the MAC CE includes:

An example of the MAC CE is given in fig. 3, where:

and the Activation indicates that CG/SPS configuration needs to be activated, the default value is 0, the index of the SPS/CG configuration to be activated is followed, the length is 8-32 bits, and the specific bit number is consistent with the configuration number of the SPS/CG. When the nth bit value of the field is 1, the nth CG/SPS configuration is activated.

The Deactivation indicates that CG/SPS configuration needs to be deactivated, the default value is 1, the index of the SPS/CG configuration to be deactivated is followed, the length is 8-32 bits, and the specific bit number is consistent with the CG/SPS configuration number. And when the nth bit value of the domain is 1, the nth CG/SPS configuration is deactivated.

Suspend indicates that there is a CG/SPS configuration to Suspend execution, the default value is 1, and then the CG/SPS index to Suspend is followed by a corresponding timer, wherein the bit occupied by the timer is related to the maximum Suspend duration of the system, and fig. 3 is assumed to be 6 bits.

In addition, since the MAC CE is filled in bytes (byte), a reserved bit R may be left behind each indication field.

C) The first configuration message is an RRC signaling, the RRC signaling includes a preset information element IE, and the preset IE specifically includes:

For example, the activation, deactivation, and suspend of the SPS/CG configuration may be performed through an RRC setup message or an RRC reconfiguration message. Specifically, an IE periodicityresourceset may be newly added, containing the following variables:

referring to fig. 4, an embodiment of the present invention further provides a terminal configuration method, when applied to a terminal side, including:

step 41, receiving a first configuration message sent by a network, where the first configuration message includes at least one of the following: at least one SPS/CG configuration activated; deactivated at least one SPS/CG configuration; at least one SPS/CG configuration suspended and its suspension time.

Here, the SPS/CG configuration included in the first configuration message is indicated by an index or an identification of the SPS/CG configuration. In addition, the specific form of the first configuration message may refer to the foregoing description, and is not described herein again.

And step 42, executing the corresponding SPS/CG configuration according to the first configuration message.

Here, the terminal may perform at least one of the following operations for one or more SPS/CG configurations according to the first configuration message: activation, deactivation and suspension.

In the above manner, the embodiment of the invention can realize flexible SPS/CG configuration.

According to at least one embodiment of the present invention, before step 41, the method further comprises:

receiving a second configuration message sent by a network, wherein the second configuration message comprises common configuration parameters shared by each SPS/CG configuration; and receiving a third configuration message sent by a network, wherein the third configuration message comprises additional configuration parameters special for each SPS/CG configuration supported by the terminal; wherein the configuration parameters of each SPS/CG configuration comprise the common configuration parameters and additional configuration parameters special for the SPS/CG configuration.

Through the above steps, the embodiment of the invention can only send the additional configuration parameters of the SPS/CG supported by the terminal to the terminal, thereby reducing the overhead of configuration signaling.

Several examples are provided next, and the above configuration method is explained in more detail.

Example 1:

assuming that the network supports 16 SPS configurations at most, the index thereof is 1-16, firstly, the network issues Common configuration of the 16 SPS configurations through broadcasting. For the UE1, only SPS configuration of the indexes 7-11 is supported, the network issues Delta configuration of SPS configuration with indexes 7-11 in a broadcasting or dedicated signaling mode, and firstly configures the configuration with UE activation index7 and 8 for service transmission. Subsequently, along with the change of the UE service, the network needs to activate the SPS configuration with index of 9-11, deactivate the SPS configuration with index of 8, and suspend the SPS configuration with index of 7, wherein the suspend duration is 100 symbols. It is assumed here that the duration of the suspend is 2^8 symbols at most, so each timer takes 8 bits. The network performs the above operation through the DCI format, and only the DCI values related to this part are described here:
