Description

Method and device for activating and releasing non-dynamic scheduling transmission Technical field

This application relates to the field of communication technology, and in particular to a method and device for activating and releasing non-dynamic scheduling data transmission.

Background technique

In a cellular network mobile communication system, uplink data transmission methods include data transmission based on dynamic grant (grant-based, GB) or dynamic scheduling, and non-dynamic scheduling data transmission. Non-dynamic scheduling data transmission includes semi-persistent scheduling (SPS) data transmission or grant-free (GF) data transmission. Among them, the process of data transmission based on dynamic grant (grant based, GB) or dynamic scheduling includes: when the terminal has an uplink data transmission demand, it usually sends a scheduling request (scheduling request, SR) or reports a non-empty buffer status report ( Buffer state report, BSR). After receiving the SR or BSR, the base station sends downlink control information (DCI) to the terminal. The DCI carries an uplink grant (UL grant) to authorize the terminal to use the specified time-frequency resources. Use the specified transmission parameters, such as the specified modulation and coding scheme MCS (Modulation and Coding Scheme), etc., to send uplink data. Because dynamic scheduling can efficiently use the real-time channel information between the terminal and the base station, and specify the location, size, and transmission parameters of the appropriate time-frequency resources for each transmission of the terminal, the dynamic scheduling of uplink transmission usually has a higher reliability.

The non-dynamically scheduled data transmission process includes: the base station configures the time-frequency resources and transmission parameters used for uplink data transmission for the terminal in a semi-static manner through high-level signaling and/or physical layer signaling. When the terminal has uplink data transmission requirements, it does not need to go through the process of sending SR or BSR to the base station, and does not need to wait for the uplink authorization process. Instead, it directly uses the semi-statically configured time-frequency resources and transmission parameters to send data to the base station to achieve data recovery. Come and go, so as to achieve the purpose of reducing transmission delay, signaling overhead and terminal power consumption.

In order to support multiple services with different requirements for delay and reliability at the same time, the industry is considering supporting multiple sets of configuration parameters (for example, 12 sets) that allow non-dynamic scheduling transmission on the same bandwidth part in 5G communications. ). In this case, the base station will create an index (index) or identification (ID) for each set of configuration parameters, and deliver the index or identification information and its corresponding configuration parameters to the terminal. The base station can activate or release corresponding configuration parameters based on the index or identification corresponding to each set of configuration parameters.

In the technical solutions provided in the embodiments of the present application, the device used to implement the functions of the terminal is a terminal or a UE as an example to describe the technical solutions provided in the embodiments of the present application.

Among them, in the embodiments of the present application, the term "data transmission" can also be described as "communication", "information transmission" or "transmission". This technical solution can be used for wireless communication between a scheduling entity and a subordinate entity, and those skilled in the art can use the technical solution provided in the embodiments of this application to perform wireless communication between other scheduling entities and subordinate entities, such as a macro base station and a micro base station. Wireless communication between, for example, the wireless communication between the first terminal and the second terminal.

In the embodiment of the present application, the uplink data transmission of the base station may adopt dynamic scheduling and non-dynamic scheduling data transmission. Dynamic scheduling can also be called GB.

As shown in Figure 2, the dynamically scheduled uplink data transmission may include the following processes:

S201. When the terminal has a demand for uplink data transmission, it usually sends a scheduling request (SR) to the base station through a physical uplink control channel (PUCCH), or the terminal will use a physical uplink shared channel (physical uplink shared channel) channel, PUSCH) to report a non-empty BSR to the base station. The base station receives the SR/BSR sent by the terminal.

BSR is usually sent through media access control (MAC) layer signaling and carried in the media access layer control element (MAC CE) in the packet header of the data packet

S202: After receiving the SR or non-empty BSR sent by the terminal, the base station sends DCI to the terminal through a physical downlink control channel (PDCCH).

The DCI carries an uplink grant (UL grant), which is used to authorize the terminal to send uplink data using specified transmission parameters on specified time-frequency resources. For example, a specified modulation and coding scheme (MCS) is used to send uplink data.

S203. The terminal uses the specified transmission parameters on the specified time-frequency resources according to the DCI to send uplink data through the PUSCH.

Because dynamic scheduling can efficiently use the real-time channel information between the terminal and the base station, and specify the location, size, and transmission parameters of the appropriate time-frequency resources for each transmission of the terminal, the dynamic scheduling of uplink transmission usually has a higher reliability.

In the uplink data transmission process based on dynamic authorization, the terminal needs to send SR or BSR to the base station before sending data, and the base station will authorize through DCI. This process will introduce delay and PDCCH signaling overhead. At the same time, because the reception of PDCCH usually requires the terminal to use different control channel elements CCE (Control Channel Element) aggregation levels (Aggregation Level), and/or different DCI formats (Format), and/or different DCIs on different time-frequency resources. The length, and/or different radio network temporary identifiers (Radio Network Temporary Identifier) perform blind detection, which requires a lot of power consumption. Data transmission using non-dynamic scheduling can reduce time delay, reduce signaling overhead, and reduce terminal power consumption.

Taking the New Radio (NR) technology of 5G communication as an example, NR supports two types of non-dynamic scheduled data transmission, namely non-dynamic downlink data transmission and non-dynamic uplink data transmission. Non-dynamic downlink data transmission includes SPS downlink data transmission, and GF data transmission is used for uplink transmission. Non-dynamic scheduling uplink data transmission can also be called authorization-free uplink data transmission, scheduling-free uplink data transmission, uplink data transmission without dynamic scheduling (uplink data transmission without dynamic scheduling), and uplink data transmission without dynamic authorization (uplink). data transmission without dynamic grant), uplink data transmission with configured authorization (uplink data transmission with configured grant), or uplink data transmission configured by high-layers (uplink data transmission configured by high-layer). Uplink data transmission includes PUSCH transmission.

GF uplink data transmission includes PUSCH transmission based on type 1 configuration authorization (Type 1 PUSCH transmission with a configured grant, or Type 1 configured grant PUSCH transmission) and PUSCH transmission based on type 2 configuration authorization (Type 2 PUSCH transmission with a configured grant, or Type 2 configured grant PUSCH transmission).

In the PUSCH transmission of the first type of configuration authorization, the base station sends the configuration authorization configuration (configured grant configuration, also called configuredGrantConfig) to the terminal through RRC signaling. The configured grant configuration is used to configure the period, including time domain resources, Open-loop power control related parameters, waveform, redundancy version sequence, number of repetitions, frequency hopping mode, resource allocation type, HARQ process number, demodulation reference symbol (DMRS) related parameters, modulation and coding scheme table, resources Block (resource block group, RBG) group size, time domain resources, frequency domain resources, modulation and coding scheme (modulation and coding scheme, MCS) including all transmission resources and transmission parameters. After receiving the configured grant configuration, the terminal can immediately use its configured transmission parameters to perform PUSCH transmission on the configured time-frequency resources.

In the PUSCH transmission based on the second type of configuration authorization, a two-step resource configuration method is adopted: First, the configuredGrantConfig configuration includes the period of time domain resources, open-loop power control related parameters, waveforms, redundancy version sequence, number of repetitions, and frequency hopping. Mode, resource allocation type, HARQ process number, demodulation reference signal related parameters, MCS table, resource block RBG group size, etc., including transmission resources and transmission parameters; then use the CS-cell radio network temporary identifier (radio network) Temporary identifier (RNTI) scrambled DCI activates the second type of PUSCH transmission based on configuration authorization, and at the same time, the DCI configures other transmission parameters including time domain resources, frequency domain resources, DMRS, MCS, etc. When the terminal receives the high-level parameter configuredGrantConfig, it cannot immediately use the resources and transmission parameters configured by the configuredGrantConfig to perform PUSCH transmission, but must wait until the corresponding activated DCI is received and other resources and transmission parameters are configured before PUSCH transmission can be performed.

Since the time-frequency resources for non-dynamically scheduled data transmission are all configured by the base station in a semi-static manner, which is equivalent to pre-configured or reserved for the terminal, these resources still exist even if the terminal has no uplink data transmission requirements. As shown in Figure 3, taking the non-dynamically scheduled data transmission as GF uplink data transmission as an example, the uplink GF resources configured by the base station in a semi-static manner recur in the time domain in a periodic manner, and the GF resources in each cycle are used To transmit an upstream data packet. When the terminal arrives on the periodic GF resource, if there is an uplink data transmission demand, it will send an uplink data packet on the arriving GF resource. If the uplink data transmission demand is generated after the last available GF resource in a certain period (for example, period 1 in Fig. 3), it has to wait until the GF of the next period (for example, period 2 in Fig. 3) Resources. In this case, the data transmission delay will be longer.

In order to support a variety of services with different requirements for delay and reliability, the industry is considering supporting multiple sets of configuration parameters (for example, 12 sets) that allow non-dynamically scheduled data transmission on the same bandwidth part (Bandwidth Part) in 5G communications. ). In this case, the base station will create an index (index) or identification (ID) for each set of configuration parameters, and deliver the index or identification information and its corresponding configuration parameters to the terminal. In an embodiment of the present application, a set of configuration parameters may refer to parameters required to complete a PUSCH transmission or PDSCH transmission. For example, for the PUSCH transmission of the first type of configuration authorization, a set of configuration parameters refers to a configuredGrantConfig For all the parameters in the second type of configuration authorization PUSCH transmission, a set of configuration parameters refers to all the parameters in a congfiguredGrantConfig and the corresponding parameters configured to activate the DCI. It should be noted that the parameters included in the configuredGrantConfig used for PUSCH transmission of the first type of configuration authorization and the configuredGrantConfig used for the second type of configuration authorization of PUSCH transmission are not exactly the same. For details, please refer to the standard 3GPP TS38.331. Related description.

In this application, configuration data transmission (uplink data transmission and downlink data transmission) refers to configuration of transmission parameters used for data transmission; activation of data transmission refers to activation of transmission parameters of data transmission so that it can be used for subsequent data transmission; release Data transmission refers to the release (deactivation) of the transmission parameters of the data transmission so that it is in an invalid (invalid) state and cannot be used for subsequent data transmission.

Taking the non-dynamically scheduled data transmission as the PUSCH transmission authorized based on the second type of configuration as an example, when the base station configures multiple sets of transmission parameters for the PUSCH transmission authorized based on the second type of configuration for the terminal, the base station needs to activate each set of transmission parameters. In an activation method (called separate activation), the base station issues an activated DCI each time, and the DCI carries a set of transmission parameter indexes (or identifiers), and the set of transmission parameters indicated by the index is activated, if necessary To activate multiple sets of transmission parameters, multiple activated DCIs need to be issued, and each activated DCI needs to carry the index corresponding to the activated set of transmission parameters. In a release method (called separate release), if the transmission parameters of PUSCH transmission authorized based on the second type of configuration need to be released, the base station issues a release DCI each time, and the release DCI carries a set of transmission parameter indexes (or ID), the set of transmission parameters indicated by the index is released. If multiple sets of transmission parameters need to be released, multiple release DCIs need to be issued, and each activated DCI needs to carry the index corresponding to the released set of transmission parameters.

In the above method, if multiple sets of parameters need to be activated or released, the base station needs to send multiple DCIs. Therefore, the signaling overhead of the above method is large. Therefore, a joint activation/release method is proposed. In the joint activation method, the base station can configure an active state set (each state set has a maximum of, for example, 16 state values), the active state set contains one or more state values, and each state value corresponds (or is associated) One or more indexes (or identifiers), each index corresponds to a set of transmission parameters for PUSCH transmission authorized based on the second type of configuration, the base station issues the active DCI carrying the state value, and the transmission corresponding to the index associated with the state value The parameter is the activated transmission parameter. In the joint release method, the base station can configure a release state set (each state set has a maximum of, for example, 16 state values), the active state set contains one or more state values, and each state value corresponds (or is associated) One or more indexes (or identifiers), each index corresponds to a set of transmission parameters for PUSCH transmission authorized based on the second type of configuration, the base station issues the release DCI carrying the status value, and the transmission corresponding to the index associated with the status value The parameter is the released transmission parameter. In the above method, one DCI can activate or release multiple sets of transmission parameters, thereby saving signaling overhead. In the embodiments of the present application, the active state set can also be referred to as the index set of the active group or the index set of the configuration group, and each state value can also be referred to as the index (or identification) of the active group or the index set of the configuration group. Index (or identification).

Although the above-mentioned separate activation/release method has high signaling overhead, it has high flexibility. The above-mentioned joint activation/release method has the advantage of saving signaling overhead, but its flexibility is not high compared to the single activation/release method.

Furthermore, the embodiment of the present application provides a method for activating/releasing non-dynamic scheduling data transmission, which can save signaling overhead and also allows for relatively high flexibility.

The network device configures multiple transmission configurations for non-dynamically scheduled data transmission for the terminal device through high-level signaling (for example, RRC signaling), and each transmission configuration includes configuration information of a set of transmission parameters for non-dynamically scheduled data transmission. Different transmission configurations may be different configurations of parameter values for the same set of transmission parameters. In the two transmission configurations, if only one parameter has a different parameter value, the two transmission configurations can be regarded as different transmission configurations. For example, in transmission configuration 1, the time domain resource period is 5 time slots, in transmission configuration 2, the time domain resource period is 10 time slots, transmission configuration 1 and transmission configuration 2 except for the configuration of time domain resource period Except for the difference, the parameter values of other parameters are the same. In this case, transmission configuration 1 and transmission configuration 2 can be regarded as different transmission configurations.

The network device configures the activation state set and/the release state set for the terminal through signaling. The active state set contains at least one state value, and each state value is associated (or corresponding to) one or more transmission configurations. The release state set contains at least one state value, and each state value is associated with (or corresponds to) one or more transmission configurations. The activation state set and the release state set can be the same or different. If the activation state set and the release state set are the same, the network device may only need to configure one state set. The state value in the activation state set and the value in the release state set may be different or the same. The transmission configuration associated with the same state value in the activated state set and the released state set may be the same or different. The state value is associated with the transmission configuration, and the state value may be associated with the index (identification or sequence number) of the transmission configuration.

For ease of understanding, the network device is configured with 12 transmission configurations (the indexes are 0-11 as an example), and a transmission state set containing 4 state values (state values are 0, 1, 2, 3) As an example, this application provides an example of the corresponding relationship between the state value of the active state set and the index of the transmission configuration, as shown in Table 1.

Table 1. Correspondence between the state value in the active state set and the index of the transmission configuration

It should be noted that the examples of the above tables are only for the convenience of understanding the solutions provided in this application, and should not be construed as limiting the application.

The network device can configure the active state set for the terminal device through RRC signaling. Taking the non-dynamically scheduled data transmission as the PUSCH transmission based on the second type of configuration authorization, and a transmission configuration including the configuration information of the parameters included in the configuredGrantConfig of the second type of configuration authorization PUSCH transmission as an example, this application provides a The information structure used to configure the above state set in RRC signaling is as follows:

Among them, Type2Configuredgrantconfig-ActivateStateList represents the activation state set of the network device configuration, including a maximum of 16 states. Type2Configuredgrantconfig-ActivateState represents a state in the activated state set, stateValue is the value of the state, and the value range is 0 to 15, type2-CGConfig contains one or more index values ConfiguredGrantConfigIndex, which represents the index value associated with the state, each The index value corresponds to a transmission configuration. It is understandable that in addition to the above information structure, there may be other information structures that can also implement the configuration of the activation state machine, which is not limited in this application.

The method of configuring the release state set is the same as the method of configuring the activation state set. You only need to replace the "activation state (or ActivateState)" with the "release state (or ReleaseState)", which will not be repeated here.

It is understandable that, in addition to the manner in which the network device can configure the release state set and the release state set for the terminal through signaling, the terminal device may obtain the release state set and the release state set in other ways. For example, the terminal device determines the transmission configuration corresponding to each state value according to a preset rule. In this case, the network device also determines the transmission configuration corresponding to each state value according to the same preset rule. The preset rule may It is specified by a standard protocol, or it can be negotiated between the network device and the terminal device.

As shown in FIG. 4, the process of a method for activating non-dynamic scheduling data transmission provided by an embodiment of the present application is as follows. The execution body of this method takes terminals and network devices as examples, and the non-dynamic scheduling data transmission in this method takes PUSCH transmission authorized based on the second type of configuration as an example.

S401: The terminal receives the DCI sent by the network device for activating non-dynamic scheduling data transmission.

If the DCI received by the terminal device meets the preset condition, the DCI is used to activate PUSCH transmission based on the second type of configuration authorization. The preset condition is specified by the standard, and is used to determine whether the DCI is the DCI used to realize the activation function.

In an embodiment, the above conditions specifically include:
