Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
In the present disclosure, "first" and "second" are used to distinguish different objects, and are not used to indicate a meaning such as a size or a timing. For example, the first type frame structure and the second type frame structure represent two types of frame structures.
The present disclosure provides a radio frame structure including different types of frame structures, for example, including: the frame structure comprises a first type frame structure and a second type frame structure, wherein the first type frame structure and the second type frame structure have the same subframe length, the number of subframes in each frame can be the same, and at least one of the number of TTIs contained in the subframes and the number of symbols contained in the TTIs is different. The average length of the TTIs contained in the first type frame structure is different from the average length of the TTIs contained in the second type frame structure, and the first type frame structure is called a short TTI frame structure, and the second type frame structure is called a long TTI frame structure, on the assumption that the average length of the TTIs contained in the first type frame structure is smaller than the average length of the TTIs contained in the second type frame structure. The radio frame structure consists of frames, subframes, slots, symbols, cyclic prefixes in the time domain and subcarriers in the frequency domain. A frame comprises a plurality of subframes, each subframe is divided into a plurality of time slots, each time slot is composed of a plurality of symbols, and each symbol comprises a cyclic prefix. For example, a 10ms frame is taken in the time domain, each frame is divided into 10 1ms subframes, each subframe is divided into 2 0.5ms slots, and each slot is composed of 6 or 7 OFDM symbols. The frequency domain is divided into a plurality of sub-carriers, and the bandwidth of each sub-carrier is 15KHz, for example. The frequency domain is divided into a plurality of sub-bands, and the first type frame structure and the second type frame structure are respectively positioned in different sub-bands. For example, as shown in FIG. 1, the short TTI frame structure is located in a sub-band centered in the system bandwidth and the long TTI frame structures are distributed on both sides of the first type of frame structure. The sub-band in which the short TTI frame structure is located is called a short TTI sub-band, and the sub-band in which the long TTI frame structure is located is called a long TTI sub-band. The basic units of the short TTI frame structure and the long TTI frame structure, such as the size of symbols, cyclic prefix, subcarriers, and slots, may be identical. The proportion of the system bandwidth occupied by the first type frame structure or the second type frame structure is configurable, and configuration examples will be given later.
The first type frame structure may include a plurality of first type subframe patterns, and at least one of the number of TTIs and the number of symbols included in a TTI is different for different first type subframe patterns. The second type frame structure may include a plurality of second type subframe patterns, different second type subframe patterns having at least one of a different number of TTIs and a different number of symbols included in a TTI. Two first type subframe patterns (i.e., short TTI subframe pattern 1 and short TTI subframe pattern 2) and two second type subframe patterns (i.e., long TTI subframe pattern 1 and long TTI subframe pattern 2) are exemplarily shown in fig. 2. Taking the short TTI subframe pattern 1 as an example, it includes 4 TTIs, each TTI length is 4, 3, 4, 3 in sequence, and the average TTI length is 3.5. Taking long TTI subframe pattern 2 as an example, it includes 3 TTIs, each TTI length is 5, 4, 5 in sequence, and the average TTI length is 4.7. It is clear that these subframe patterns are only examples, and that other subframe patterns are possible.
The disclosure also provides a physical channel structure of the aforementioned radio frame structure. The physical channel structure includes, for example, a synchronization signal, a physical broadcast channel, a physical control channel, a physical data channel, and the like. Each channel is described separately below.
1. Synchronization signal
The synchronization signals typically include a primary synchronization signal and a secondary synchronization signal. The primary synchronization signal may be, for example, a Zadoff-Chu (ZC) sequence, and the secondary synchronization signal may be, for example, an M sequence.
In the time domain, the primary synchronization signal and the secondary synchronization signal are located at a certain symbol of a radio frame appointed by the system. For example, as shown in fig. 3, the primary synchronization signal is located in the 1 st slot (shown) and the last symbol of the 11 th slot (not shown) of each radio frame, and the secondary synchronization signals are located before the primary synchronization signal and each occupy one symbol. The terminal can obtain the time slot boundary timing by detecting the primary synchronization signal and the secondary synchronization signal.
In the frequency domain, the main synchronization signal and the auxiliary synchronization signal are transmitted at the frequency domain position with the default system bandwidth, so that the terminal is ensured to be synchronous with the system under the condition of no bandwidth allocation prior message. For example, the primary synchronization signal and the secondary synchronization signal are located at a center frequency of the system bandwidth, and are transmitted within a center bandwidth, e.g., 6 resource blocks.
2. Physical broadcast channel
The physical broadcast channel is located at the system bandwidth center frequency. For example, the physical broadcast channel is centered within the short TTI sub-band. The physical broadcast channel provides frame structure configuration information. The frame structure configuration information and other information provided by the physical broadcast channel are coded and rate-matched, and then transmitted at the time-frequency resource position designated by the system. For example, as shown in fig. 3, the physical broadcast channel information is divided into 4 independent self-decoding units with equal size, where the 4 independent self-decoding units are located on 6 resource blocks in the center of the system bandwidth in the frequency domain, and are respectively located on 4 consecutive symbols, such as 8 th to 11 th symbols, in the radio frame in the time domain.
3. Physical control channel
The physical control channels comprise a first type physical control channel and a second type physical control channel, wherein the first type physical control channel is positioned in a sub-band where the first type frame structure is positioned, and the second type physical control channel is positioned in a sub-band where the second type frame structure is positioned. For example, as shown in fig. 3, the physical control channel is divided into a long physical control channel and a short physical control channel according to the supported subframe pattern, and is respectively located in the long TTI sub-band and the short TTI sub-band, and is respectively responsible for physical resource control of the long TTI sub-band and the short TTI sub-band, for example, time and frequency resources used by uplink and downlink transmission of the terminal are indicated, and a terminal power control adjustment command and the like.
As shown in fig. 3, the number of short physical control channel symbols is variable, and occupies 1 to 2 symbols according to different subframe patterns. Each subframe within a short TTI subband may contain 1 to multiple short physical control channels, the number of which may be indicated by the system.
As shown in fig. 3, the long physical control channel occupies the first three symbols of each subframe, e.g., in the long TTI sub-band.
4. Physical data channel
The physical data channels are located in resource blocks other than the above channels, e.g. the resource blocks shown in fig. 3 with open boxes.
The disclosure also provides a configuration method of a wireless frame structure of a system based on terminal-assisted implementation. As shown in fig. 4, the method 40 includes:
and step 410, counting the frame structure selection information fed back by the terminal.
The frame structure selection information fed back by the terminal may be, for example, a subframe pattern type or a frame structure type. With coarser granularity feedback, the terminal may feed back frame structure types such as a first type frame structure (short TTI frame structure) or a second type frame structure (long TTI frame structure) that is preferred by itself. The terminal can feed back subframe mode types such as a certain first type subframe mode (short TTI subframe mode) or a certain second type subframe mode (long TTI subframe mode) which are preferred by the terminal.
And step 420, determining the frame structure configuration information of the system at the next stage according to the statistical information.
The frame structure configuration information of the system includes, for example, the proportion of the system bandwidth occupied by different types of frame structures, subframe modes, and the like.
As an example, the ratio of the system bandwidth occupied by the first type frame structure and the second type frame structure in the next-phase system is determined according to a ratio of a first product and a second product, wherein the first product is a product of the number of terminals selecting the first type frame structure and the amount of historical data, and the second product is a product of the number of terminals selecting the second type frame structure and the amount of historical data.
As an example, according to the terminal selection information of the subframe pattern, determining a subframe pattern that can be used by the system at the next stage; or, determining the subframe mode which can be adopted by the system in the next stage according to the terminal selection information of the subframe mode and the radio frame structure configuration scheme of the adjacent cell system.
For example, it is determined that the next-stage preferred configuration scheme of the long TTI frame structure selects the most long TTI subframe patterns for each terminal, and if the ratio of the number of terminals selecting the most long TTI subframe patterns to the total number of terminals selecting the long TTI frame structure exceeds a certain threshold (e.g., 60%), the candidate configuration scheme of the long TTI frame structure is not set, otherwise, the candidate configuration scheme of the long TTI frame structure is set to select the next-most long TTI subframe patterns for each terminal. And determining the optimal configuration scheme of the next-stage short TTI frame structure to select the most short TTI subframe modes for each terminal, if the proportion of the number of the terminals selecting the most short TTI subframe modes to the total number of the terminals selecting the short TTI frame structure exceeds a certain threshold value (such as 60%), not setting the candidate configuration scheme of the short TTI frame structure, otherwise, setting the candidate configuration scheme of the short TTI frame structure to select the short TTI subframe modes for each terminal for a plurality of times. If the system has no frame structure candidate configuration scheme, the system determines the frame structure preferred configuration scheme as the frame structure final configuration scheme of the system of the next stage. If the system has the frame structure candidate configuration scheme, the system receives the frame structure configuration scheme of the adjacent cell, if the candidate configuration scheme is the same as the frame structure configuration scheme of the adjacent cell, the frame structure candidate configuration scheme is determined as the final configuration scheme of the frame structure of the system of the next stage, so that the interference is reduced, otherwise, the preferred configuration scheme of the frame structure is determined as the final configuration scheme of the frame structure of the system of the next stage.
The wireless frame structure configuration of the system is realized based on the terminal assistance, so that the wireless frame structure configuration of the system is more reasonable.
The disclosure also provides a configuration method of a wireless frame structure of a system based on terminal-assisted implementation. As shown in fig. 5, the method 50 includes:
The system may broadcast the frame configuration information to each terminal through a physical broadcast channel, or may transmit the frame configuration information to the terminal point to point through an RRC (Radio Resource Control) message.
An example of frame structure configuration information is as follows.
In step 520, the terminal determines the preferred mode of the frame structure of the terminal and sends the preferred mode to the system.
The terminal may determine its frame structure preferred mode according to information such as terminal attributes and service characteristics. For example, if the terminal attribute is a car networking terminal or the service characteristic is a low-latency application, it is determined that the preferred mode of the frame structure is short TTI mode 1. If the terminal attribute is an industrial control sensor or the service characteristic is ultra-low delay application, the frame structure preferred mode is judged to be a short TTI mode 2. If the terminal attribute is a mobile multimedia terminal or the service characteristic is a mobile broadband application, the frame structure preferred mode is determined to be a long TTI mode 1. And if the terminal attribute is the intelligent water meter terminal or the service characteristic is the application of the large-connection Internet of things, judging that the frame structure optimal mode is the long TTI mode 2.
The terminal may send the frame structure preference mode to the system through an uplink physical control channel as uplink control information, or send the frame structure preference mode to the system through an RRC message.
In step 540, the system determines the frame configuration information of the next stage system according to the statistical information. See step 420 for details.
The system may broadcast the updated frame structure configuration information to each terminal through a physical broadcast channel, or may transmit the updated frame structure configuration information to the terminal point to point through an RRC message.
And step 560, the terminal initiates access or data transmission according to the new frame structure configuration.
The wireless frame structure configuration of the system is realized based on the terminal assistance, so that the wireless frame structure configuration of the system is more reasonable, and the service transmission requirement of the terminal side is better met.
