Description
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for indicating system configuration.
Background
Currently, in the fifth Generation mobile communication technology (5-Generation,5G) system, uplink and downlink traffic will exhibit more dynamic changes. In the 5G system, the diversified service drives the frame structure of the 5G system to have an inclusive property so as to effectively meet the requirements of various services, and the subframe type and/or Transmission Time Interval (TTI) type also show diversification. The traditional static/semi-static uplink and downlink configuration indication, subframe types and TTI types are single, and the requirements of a 5G system cannot be met. Thus, in a 5G frame structure, the subframe/TTI configuration will exhibit a more dynamic change.
In the prior art, a transmission period of system configuration information and an advance time range of the system configuration information acquired by a terminal are in an inverse relation. That is, the longer the period of the information indicating the system configuration is, the earlier the terminal can learn the system configuration in the period; conversely, the smaller the period of the information indicating the system configuration, the later the terminal will know the system configuration within the period. In view of the above requirements, system configuration information is indicated in the fixed downlink subframe, including uplink and downlink configuration, subframe and/or TTI type. By adopting the mode, the dynamic system configuration indication is realized to a certain extent, and the terminal can acquire the system configuration earlier. In addition, in the prior art, a method of dynamically indicating the subframe and/or TTI configuration per subframe and/or TTI may also be adopted, so that a subframe and/or TTI-level system configuration indication may be implemented, and a requirement of a User Equipment (UE) for Discontinuous Reception (DRX) may be met.
However, when the fixed downlink subframe indicates system configuration information, the dynamic period depends on the period of the fixed downlink subframe; on the other hand, if the UE receiving non-continuously is not awake in the fixed subframe, the UE cannot obtain the system configuration information in the fixed downlink subframe period, which will cause the UE to perform no behavior in this period, and cannot meet the requirements of multiple UE types. When the method of dynamically indicating the subframe and/or TTI configuration per subframe and/or TTI is adopted, the UE cannot acquire the configuration Information of other subframes/TTIs in advance, so that the UE cannot know when to terminate the data receiving or sending, the Downlink Control Information (DCI) and the Channel State Information (CSI) measurement and the like; thereby affecting the efficiency of the system and increasing the energy consumption at the UE end.

As described in the background, when a fixed downlink subframe indicates system configuration information, the dynamic period depends on the period of the fixed downlink subframe; on the other hand, if the UE of DRX is not awake in the fixed subframe, the UE cannot obtain the system configuration information in the fixed downlink subframe period, which will cause the UE to perform no behavior in this period, and cannot meet the requirements of multiple UE types. When the method of dynamically indicating the subframe and/or TTI configuration per subframe and/or TTI is adopted, the UE cannot acquire the configuration Information of other subframes/TTIs in advance, so that the UE cannot know when to terminate the data receiving or sending, the Downlink Control Information (DCI) and the Channel State Information (CSI) measurement and the like; thereby affecting the efficiency of the system and increasing the energy consumption at the UE end.
In the 5G system, the type of Transmission Time Interval (TTI) will be diversified, and reference can be made to fig. 1 and fig. 2. Fig. 1 is a schematic structural diagram of different types of downlink TTIs according to an embodiment of the present invention.

In addition to the above TTI types, the TTI or frame structure in low latency service requirements has the characteristic of self-inclusion, which means that data transmission and corresponding feedback occur in the same TTI or subframe.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 3 is a flowchart of a system configuration indication method according to an embodiment of the present invention. The specific steps of the system configuration indication method will be described in detail with reference to fig. 3.
The system configuration indication method shown in fig. 3 is applied to the base station side.
Step S301: configuration information for each transmission time is determined.
Step S302: and transmitting the configuration information to the user terminal in each transmission time.
Wherein the configuration information comprises a configuration within a plurality of transmission times; the configuration information is used to indicate an operation of a User Equipment (UE).
In a specific implementation, the configuration information includes a configuration in a current transmission time and a configuration in at least one transmission time that is continuous after the current transmission time. For example, configuration information may be transmitted in each subframe, where the configuration information includes configuration information of a current subframe and configuration information of N subsequent consecutive subframes; n may be any positive integer.
Specifically, the number of consecutive transmission times may be the same or different.
In a specific implementation, the transmission time may be a length of an independent decoding transmission in the radio link, for example, the transmission time may be a conventional TTI, and the length is one subframe, i.e., 1 ms; or a Shortened Transmission Time Interval (STTI), which may be 2, 4, or 7 symbols (Symbol). The transmission time may be used for sending downlink data and control information of the base station, and may also be used for sending uplink data of the user terminal.
It is understood that the length of the transmission time may be any practicable length, and the embodiment of the present invention is not limited thereto.
Specifically, the configuration information is transmitted at the front end of each transmission time. For example, the configuration information is transmitted 1 to 3 symbols before the transmission time. Specifically, the configuration information is carried in downlink control information. For example, the configuration information is carried by the common control information, and since the user terminals can all demodulate the common control information, the user terminal to receive the configuration information can acquire the configuration information.
In a specific implementation, the configuration information includes uplink and downlink configuration information and a transmission time type. Specifically, the uplink and downlink configuration information may be used to indicate whether the corresponding transmission time is used for uplink transmission or downlink transmission; the transmission time type may be used to indicate the type of information transmitted within the corresponding transmission time, and may be, for example, data and/or control information.
The embodiment of the invention can simultaneously meet the requirement of dynamic indication of the configuration information by transmitting the configuration in a plurality of transmission time in each transmission time, and the user terminal can acquire the requirement of the configuration information in advance and can also meet the requirements of various user terminals.
Accordingly, referring to fig. 4, fig. 4 is a flowchart of another system configuration indication method according to an embodiment of the present invention.
The system configuration indication method shown in fig. 4 is used on the user terminal side.
Step S401: configuration information is received from the base station for each transmission time.
Wherein the configuration information comprises a configuration within a plurality of transmission times.
Referring to fig. 3, after step S301, the ue receives configuration information from the base station for each transmission time. Specifically, downlink control information is received at the front end in each transmission time, where the downlink control information includes a configuration in a current transmission time and a configuration in at least one transmission time that is continuous after the current transmission time. For example, the received configuration information includes configuration information for a current subframe and configuration information for N subsequent consecutive subframes.
Step S402: and based on the received configuration information, operating according to the configuration indicated by the configuration information at the corresponding transmission time.
In a specific implementation, the configuration information includes uplink and downlink configuration information and a transmission time type. The transmission time type may be used to indicate the type of information transmitted within the corresponding transmission time, and may be, for example, data and/or control information. And when the uplink and downlink configuration information is uplink transmission, the user terminal sends the information specified by the transmission time type to the base station at the corresponding transmission time. And when the uplink and downlink configuration information is downlink transmission, the user terminal receives the information specified by the transmission time type at the corresponding transmission time.
Specifically, the transmission time types may be various types as follows: the self-contained transmission time comprises the transmission time of the control information only, the transmission time of the control information and partial data, the transmission time of the control information and all data and the self-contained transmission time, wherein the self-contained transmission time comprises the transmission time of downlink control and uplink control, and the transmission of the information from a source node to a terminal node and the feedback from the terminal node to the source node can be realized. For example, when the transmission time is a subframe, the corresponding subframe type may include: a subframe containing only control information; a subframe containing control information and partial data; a subframe containing control information and all data; a self-contained subframe. Or, when the transmission time is TTI, the corresponding TTI type may include: a subframe containing only control information; a subframe containing control information and partial data; a subframe containing control information and all data.
Specifically, the transmission time of the reception configuration information is earlier than or equal to the transmission time when the configuration indicated by the configuration information is performed. For example, when the configuration information includes the configuration information of the current subframe and the configuration information of N subsequent consecutive subframes, the user terminal detects DCI information of subframe N at subframe k, and then the user terminal performs corresponding operation at subframe N according to the configuration information carried in DCI; if the user terminal does not detect the DCI information of the subframe n in the subframe k, the user terminal will not have any behavior in the subframe n. Wherein k is any subframe in the subframe [ N-N, N ], and k, N and N are positive integers.
Referring to fig. 5, fig. 5 is a schematic diagram of a subframe structure according to an embodiment of the invention.
In Time Division Long Term Evolution (TD-LTE) and Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) systems, the uplink and downlink share the same frequency band, and the uplink and downlink alternate in different subframes on the Time axis.
Compared with the fixed ratio relationship between the uplink subframe and the downlink subframe in the prior art, the embodiment of the invention flexibly configures the uplink and downlink transmission time and the transmission time type in a dynamic subframe mode, and can meet various services under different application scenes.

And transmitting downlink control information in the first 1-3 symbols in the subframe 1, wherein the downlink control information comprises configuration information aiming at the subsequent symbols in the subframe 1. Specifically, the configuration information is carried in downlink control information. If the configuration information may indicate downlink configuration, the ue receives data or control information in the indicated subframe according to the downlink configuration; the configuration information may indicate uplink configuration, and the ue transmits according to the uplink configuration, for example, transmits data or feedback information in the indicated subframe.
In this embodiment, the configuration information carried in the downlink control information in the subframe 1 may instruct the ue to receive data or control information in the subframe 1, or may instruct the ue to send data or feedback information in the subframe 1.
Referring to fig. 6, fig. 6 is a schematic view of another subframe structure according to an embodiment of the invention.
Configuration information may be transmitted at the front end of the subframe N-N, and the configuration information may indicate a configuration from the subframe N-N to the subframe N, where N is a positive integer greater than or equal to 1, and N is a positive integer greater than N. In addition to the symbol carrying configuration information, the subframe N-N further includes STTI0, STTI1, STTI2, and STTI 3. The configuration information in subframe N-N may indicate the transmission time types and uplink and downlink configuration information of STTI0, STTI1, STTI2, and STTI3 in subframe N-N, for example, indicate that STTI0 is used for transmitting downlink control information, STTI1 is used for transmitting downlink data, STTI2 is used for user terminal to transmit uplink data, and STTI3 is used for user terminal to transmit downlink feedback. Further, the configuration information within subframe N-N may also indicate the transmission time type and uplink and downlink configuration information of STTI4, STTI5, STTI6, STTI7, and STTI8 within subframe N.
As shown in fig. 6, the front end of the subframe n may also transmit configuration information, and the configuration information in the subframe n may indicate the transmission time types and uplink and downlink configuration information of the STTI4, the STTI5, the STTI6, the STTI7, and the STTI8 in the subframe n, and may also indicate the transmission time types and uplink and downlink configuration information of multiple STTIs in at least one subframe after the subframe n.
