Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a method for indicating a data structure when continuous data is sent between a terminal device and a network device, and a device using the method.
Background
As the 5G new air interface (NR) first edition standard is completed, 5G will gradually expand to different domains. One important direction is the use of unlicensed bands. Compared with the licensed frequency band, the unlicensed frequency band needs to consider coexistence between different systems, typically, a Wifi system, an LTE-based LAA system, and the like. In order to make various systems coexist harmoniously, regulatory bodies of various countries adopt a forced Listen Before Transmit (LBT) technology for the use of an unlicensed frequency band, that is, data transmission can be performed only when the current channel is sensed to be unoccupied. A problem with this mechanism is that some data cannot be guaranteed to be sent at a certain location.
In the unlicensed frequency band, the data transmission needs to meet the limit of continuous data transmission duration (COT) under the limit of the regulatory rule. I.e. one continuous data transmission is limited to a certain time, e.g. 5ms, beyond which the channel needs to be released and LBT performed again. Within one COT, the transmission direction of data may change. For example, a previous part in a COT transmits downlink data, and the downlink data is followed by uplink data transmission. When the base station obtains the channel resources through LBT and starts downlink data transmission, the terminal needs to know the COT structure adopted by the base station to send data, so as to perform corresponding detection and uplink data sending preparation. The invention provides a design of a COT structure of a base station notification terminal.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flow chart of an embodiment of the method of the present application.
The embodiment of the application provides a data structure indicating method, wherein the data structure is used for continuous data transmission and comprises the following steps:
the definition data structure information (first information) includes uplink and downlink frame structure indication information (second information) and data structure length information (third information). The second information is mainly used for the network equipment to indicate the uplink and downlink configuration of each symbol in a period of time, and the second information is the uplink and downlink indication configuration of continuous N (M >1) time slots. The third information is mainly used for indicating the time length of the first information. The second information indicates, in conjunction with the third information, a time domain frame structure of the first information.
Step 101A and step 101B are selected for execution.
Step 101A, configuring an effective time slot and an invalid time slot in a data structure by a high-level signaling;
in an embodiment when the invalid timeslot is configured by higher layer signaling, the higher layer signaling configures M (M ≧ 1, e.g., M ═ 8) format parameters for each timeslot in the data structure, and activates 1 of the format parameters through downlink control signaling (e.g., through second information);
for the effective time slot, each of the format parameters is used for indicating an uplink and downlink frame structure, that is, the configuration of uplink and downlink symbols in a time slot. The format parameter may be, for example, the number (first column: format) in table 1. For example, for an effective timeslot, when the format parameter takes a value of 0, 14 symbols in the effective timeslot are all used for downlink.
For invalid slots, at least 1 format parameter is used in the higher layer configuration for indicating that the slot is invalid. For example, the invalid configuration is configured by the higher layer information, for example, if the higher layer configures a certain uplink and downlink timeslot as an invalid state, and the corresponding state number is 000, the terminal considers that the timeslot indication is invalid when the terminal receives the indication of the timeslot as 000. For another example, the invalid configuration may be a row in table 1, for example, the serial number 2 of row 4 is used as a format parameter, and the corresponding uplink and downlink configurations are all configured as "F". It may also be configured as one of the reserved values of table 1 that has not been normalized, such as one of 56 to 254.
In another embodiment when the invalid time slot is configured by higher layer signaling, the higher layer signaling includes the number of the invalid time slot. For example, the configuration of the first S timeslots in the second information is configured as an invalid configuration, and S +1 timeslots are uplink and downlink allocations of the current timeslot of the terminal, where S is a natural number smaller than N. As another example, the configuration of the last T slots in the second information may be in an invalid configuration or not in the current data structure.
For example, the nth-T slot is a first information end slot, where T is a natural number less than N. And the last continuous non-uplink or downlink configured symbols in the N-T time slot are invalid indications or are not considered to be in the current data structure.
Step 101B, indicating an invalid time slot by using third information in the downlink control signaling;
when the third information is present, the validity time of the second information (i.e., at which time slots are valid) is determined by the third information. And in the time range indicated by the third information, the uplink and downlink configuration indicated by the second information is effective configuration. The second information indication outside the time range indicated by the third information is considered as an invalid indication.
When the third information does not exist, the effective time slot of the second information is determined by the configuration of N time slots.
And indicating the uplink and downlink frame structures in the effective time slot by using second information.
Preferably, there are a plurality of active time slots, which are consecutive.
The second information contains format parameters for consecutive N time slots or format parameters for consecutive N-S-T active time slots. And determining the uplink and downlink configuration of each symbol in the time slot.
The downlink control signaling comprises first information used for indicating the data structure, and the data structure comprises an invalid time slot and an effective time slot; the first information includes second information for indicating uplink and downlink frame structures within the active timeslot.
Preferably, the first information further includes third information indicating the invalid slot. Or, when the invalid time slot is configured by a higher layer signaling, the first information does not include information for indicating the invalid time slot.
It should be noted that the first information is carried by the PDCCH and is one of DCI messages. The indication of the applicable bandwidth in the first information may be multiple carriers, or may be different Listen Before Transmit (LBT) bandwidths, which are carried by other information in the first information.
For the network device and the terminal device, the DCI Format and the indication information may be specified by a protocol, for example, the first information corresponds to a Format DCI Format2_0 in table 7.3.1-1 of 3GPP standard 38.212, and the DCI Format2_0 is specifically defined as follows:
the DCI format2_0 is used to inform the format of the slot, and the following information is transmitted through the DCI format2_0 with CRC scrambled by the SFI-RNTI:
second information, including N slot configuration information (i.e., format parameters): slot format indication 1, slot format indication 2, …, slot format indication N;
third information, which is a COT length indication (COT length indication), B bits (B bits are used to indicate the first information length);
the length of the DCI format2_0 is configured to 128bits by higher layer signaling.
For example, when the COT length indication length B is not 0, that is, there is valid third information, the valid range of the DCI Format2_0 is determined according to the indication length of the higher layer configuration. When the length B is 0, i.e. there is no valid third information, the valid range of the DCI Format2_0 is determined according to N slot configuration information (i.e. the second information), and each slot configuration information is one of table 1. Specifically, when the length B is 0, the RRC configuration gives the number of invalid timeslot configurations in the N timeslot formats
TABLE 1 uplink and downlink data format in time slot
(taken from 3GPP 38.213table 11.1.1-1: Slot formats for normal cyclic prefix, in the table, D is down, U is up, F is undefined)
Fig. 2 is a diagram illustrating a data structure commonly indicated by the second and third information.
The terminal determines a data structure according to the second information and the third information. For example, the third information indicates a length of T ═ 4.5 slots (slots), and the second information indicates 10 slots. As shown in fig. 2, the third information indicates that there are 4.5 more slots of the current COT. Since the second information includes 10 slots, it is known that the current COT has transmitted 5 slots. Starting from the current 6 th time slot (in this application, the current time slot is the time slot in which the first information is received), there are 4.5 time slots until the whole COT is finished, i.e. the COT end time is in the middle of the 10 th time slot.
Fig. 3 is a diagram illustrating a structure of second information separate indication data.
For example, the terminal decides the data structure according to the second information. For example, when the third information is not present, the indication of the first S slots in the second information is a format parameter indicating an invalid slot (the slot marked N/a in fig. 3 is an invalid slot) for the terminal to locate the position of the slot currently receiving the first information in the COT. As illustrated in fig. 3, S-4, the current slot is in the fifth slot in the COT structure. At the end of the second message, T slots may also be configured as invalid slots, with the last slot being configured as an invalid slot in fig. 3.
When the last one of the active slots contains a time demarcation point, the preceding symbol is used for uplink and the following symbol is invalid, the active slot is a special active slot. For example, the 9 th slot is a COT ending slot, the first 7 symbols in the slot are uplink, and the last 7 symbols are not in the COT. According to the present standard table, no such format exists, and a matching format, such as "uuuuuuufffffffff" needs to be added at 38.213.
Similarly, another special valid timeslot is proposed in the present application, where the last one of the valid timeslots includes a time division point, a preceding symbol is used for downlink, and a following symbol is invalid.
Fig. 4 shows an embodiment of the method of the present application for a network device (gNB).
Network equipment side:
And when the first information contains third information, defining the length of the data structure and/or the time range of the effective time slot by using the third information.
When the first information does not contain third information, defining format parameters of each effective time slot and each invalid time slot by using the second information; or, when the first information does not include the third information, determining an effective time slot and an invalid time slot according to a high-layer signaling.
When the first information includes third information, the network device performs channel coding and modulation on the first information, the second information and the third information to form a PDCCH (downlink physical control channel) containing downlink control information, and transmits the PDCCH.
Fig. 5 is an embodiment of the method of the present application applied to a terminal device.
A terminal side:
The terminal equipment identifies the first information and the second information;
and when the first information contains third information, the terminal equipment identifies the third information and determines the length of the data structure and the time range of the effective time slot according to the third information.
When the first information does not contain third information, the terminal equipment identifies the format parameters of each effective time slot and each invalid time slot according to the second information; or, when the first information does not include the third information, the terminal device determines an effective time slot and an invalid time slot according to a high-level signaling.
And the terminal equipment determines the uplink and downlink configuration of each symbol in the effective time slot in the data structure according to the second information.
When the third information exists, the terminal determines the uplink and downlink configuration of each symbol according to the format parameters contained in the second information in the effective time slot indicated by the third information;
when the third information does not exist, the terminal determines the uplink and downlink configuration of the effective time slot according to the format parameter of each time slot in the second information; or, determining an effective time slot according to the high-level configuration, and then determining the uplink and downlink configuration of each symbol according to the format parameter contained in the second information.
