Description

Meanwhile, the TDD mode is also beneficial to reducing the cost and the system overhead of using a large-scale antenna array. Therefore, it is widely believed that TDD will be the most important research direction of a new generation mobile communication system, and for the future frame structure design of TDD, a typical self-contained TDD basic resource unit structure is disclosed in the 3GPP 5G works hop working meeting in 9 months 2015, as shown in fig. 1, and this basic resource unit structure is a basic constituent unit describing resources in the future system, also called resource allocation unit, which is simply referred to as bru (basic resource unit). One BRU comprises a downlink area, an uplink area and a guard interval, wherein the downlink area comprises one or more of downlink Control signaling DL Control, downlink pilot frequency RS and downlink data; the uplink region includes one or more of uplink Control signaling UL Control and uplink data. The self-feedback refers to uplink feedback aiming at DL Control and DL data, such as HARQ ACK/NACK, channel measurement information CSI and the like, and the feedback information can be sent in the same subframe without spanning multiple subframes.

However, in future wireless networks, diverse services need to be supported, for example, wide area coverage services mainly oriented to transmission efficiency need to be supported, and services sensitive to delay and requiring low delay also need to be supported. Generally speaking, due to the overhead problem of the frame structure, the longer the basic resource unit, the smaller the overhead, and the longer the basic resource unit, the more difficult it is to support the low-latency service, which is a contradiction.

setting two or more types of subframes; the lengths of all subframes are integral multiples of BRU, and at least two subframes have different lengths;

the signal is transmitted through a combination of the above two or more types of subframes.

The set various subframes inherit the transmission mechanism of the control information of the BRU, the transmission mechanism of the reference signal of the BRU and the transmission mechanism of the data of the BRU.

Wherein the transmission mechanism inheriting the control information of the BRU comprises:

Wherein the transmission mechanism comprises one or more of the following settings:

resource occupancy, timing relationships, internal symbol structures, functions, and transmission methods.

In the embodiment of the invention, one or more Basic Resource Units (BRUs) can be compounded to obtain a long subframe (TTI) or a short subframe (TTI) according to the basic resource units, the length of the compound subframe is integral multiple of the BRUs, the front-back relation and the relative position of DL C, UL C and DL/UL data of the BRUs after compounding are not changed, and elastic stretching is carried out according to the relation of multiple. As shown in fig. 2A, a new subframe structure formed by compounding on the basis of the Basic Resource Unit (BRU) shown in fig. 1 is exemplarily introduced, for example, when the length of the original BRU is 0.2ms, the length of the long subframe is 0.4ms, or longer. The lengths of the uplink control region, the downlink control region, and the guard time GP inside the long subframe may be respectively maintained to be consistent with the BRU, or stretched in equal proportion on the basic subframe, fig. 2A is only two possible implementation manners, the first is to stretch only the total length of the subframe, and the second is to stretch the control region and the guard time. In the case of the total length stretching, other stretching such as inner stretching only GP, stretching only down control region, and stretching only up control region may be combined with each other, and the stretching of the inner region does not necessarily need to satisfy the constraint of the scale expansion. Since the total length of the long subframe is extended in an equal proportion, the long subframe and the short subframe are liable to coexist in the system. Compared with the BRU joint transmission method, the solution can reduce the system overhead.

Wherein the two or more types of subframes are multiplexed in a time division or frequency division manner in the system.

In one example, the set subframes include subframes of a first type and subframes of a second type, wherein the subframe time length of the first type is equal to or shorter than the subframe time length of the second type. The first type of subframes and the second type of subframes are in an FDD duplex mode or a TDD duplex mode; if the FDD duplex mode is adopted, the sent uplink and downlink frequency points are separated, and the control information and the data are respectively subjected to time division multiplexing on the uplink and downlink frequency points; if the TDD mode is adopted, the sent uplink and downlink frequency points are consistent, and the control information and the data are subjected to time division multiplexing on one frequency point.

In fig. 2A, the long subframe is 2 times of a BRU, and the short subframe is a single BRU, which inherit the transmission mechanism of control information, reference signal or data of the BRU. The first BRU of the long subframe inherits the transmission mechanism of the downlink control information, and the last BRU of the long subframe inherits the transmission mechanism of the uplink control information. The transmission mechanism refers to resource occupation, timing relation, internal symbol structure, function, transmission method and the like.

Referring to fig. 2B, a schematic structural diagram of an exemplary basic resource unit BRU is shown, as shown in fig. 2B, the BRU may also be in a structural manner as shown in the figure, where the number, continuity, and the like of uplink and downlink regions in the BRU are not limited.

In a specific design of the BRU, the BRU includes N OFDM symbols, each OFDM symbol has a length of 2220Ts (sample time), and the OFDM symbol includes at least a CP (cyclic prefix) and a valid data portion. The length of CP is 172Ts, the OFDM symbol length after CP removal is 2048Ts, Ts is 1/35.52us, and preferably, the number of symbols N in BRU is 2 or 4.

Referring to fig. 3, a schematic diagram of sending a feedback signal when long and short frames are used in a mixed manner is shown in fig. 3, where 2 short subframes follow one long subframe, and if the uplink feedback of the second short subframe needs to be sent in a downlink slot (slot) of the long subframe according to the HARQ timing rule of LTE, the resource collision problem occurs.

The following description is made with reference to specific embodiments.

Example 1

Referring to fig. 4, the present invention provides a signal transmission method, including:

in this example, the combination order of the subframes is subframe 1, subframe 2, and subframe 3, where subframe 1 is a short TTI, and subframe 2 and subframe 3 are long TTIs; wherein the short TTI comprises a BRU, and the feedback of the short TTI follows the timing sequence of n + 2; the long TTI consists of four BRUs, and the feedback follows a timing sequence of n +1, where n ═ 1 and 2 are both length units relative to the own TTI type.

Each TTI includes a DC (downlink control) area, a Data (Data) area, and a UC (uplink control) area. Wherein, Data may be an upstream Data area or a downstream Data area.

Step 410, the terminal receives the DL Control and DL Data to be fed back in the Data area of the subframe 1;

according to a preset feedback mechanism, a terminal needs to send feedback signals corresponding to DL Control and DL data needing to be fed back in the 2 nd short TTI after the subframe, namely a UC area in the 2 nd BRU after the subframe;

step 420, setting a punching area in subframe 2 as a transmission resource for a terminal to transmit a feedback signal;

step 420 includes the following:

1-1, taking a UC area in a 2 nd BRU corresponding to the subframe 1 in the subframe 2 as a first punching area, and taking the first punching area as a sending resource for sending the feedback signal by a terminal;

1-2, setting a second punching area (GP) before the first punching area as a transmission resource; the length of the second punching area is a guard interval;

1-3, if the data area where the punching position is located is an uplink area, setting the guard interval to be 0 or a preset first guard interval;

1-4, if the data area where the punching position is located is a downlink area, setting a preset second guard interval for the guard interval;

the first guard interval is a smaller guard interval, the second guard interval is a guard interval between uplink and downlink transmissions, if an additionally increased hole-punching part GP is due to punching of an original downlink data segment, downlink-to-uplink guard time needs to be reserved, and the guard time can refer to normal guard time of a subframe. If the original data segment is upstream data, the guard time may be eliminated or a shorter time guard band may be used.

Step 430, the terminal sends a feedback signal in a punching area set in subframe 2 as a sending resource;

step 440, the terminal receives DL Control and DL Data to be fed back in the Data area of subframe 2;

according to a preset feedback mechanism, a terminal needs a UC area in the 1 st long TTI after the subframe, namely the UC area in the 4 th BRU after the subframe to send a feedback signal corresponding to DL Control and DL data needing to be fed back;

in step 450, the terminal transmits a feedback signal in the DC region of subframe 3.

It should be noted that there may be more than one perforation position. If there is a short TTI before subframe 1, there should be a bit of data to be punctured before the current puncturing position to transmit control information. This solution performs an extra process on the normal frame structure, which is a modification of the basic frame structure.

In the following example, each data frame includes

consecutive subframes

1 and 2, the length of the subframe 1 is 1 BRU, the length of the subframe 2 is 4 BRU, a first signal to be fed back is transmitted on the subframe 1, and the feedback mechanism is n +2, that is, feedback is performed on 2 BRU after the subframe 1, and therefore, a hole needs to be punctured in the subframe 2 to transmit a second signal, where the second signal is a feedback signal corresponding to the first signal.

(1) The base station sends a first signal to the terminal 1 on the subframe 1;

terminal 1 needs to transmit the second signal to the base station in subframe 2, subframe 2 is a transmission resource allocated to terminal 1, and the corresponding position to be fed back is the data area (uplink data or downlink data) of subframe 2, so terminal 1 or the base station punctures subframe 2, and terminal 1 transmits the second signal to the base station in the puncturing area of subframe 2.

(2) The base station sends a first signal to the terminal 1 on the subframe 1;

terminal 1 needs to transmit the second signal to the base station in subframe 2, subframe 2 is a transmission resource allocated to terminal 2, and the corresponding position to be fed back is the data area (uplink data or downlink data) of subframe 2, so terminal 2 or the base station punctures subframe 2, and terminal 1 transmits the second signal to the base station in the puncturing area of subframe 2.

In this example, if the data area of the subframe 2 is uplink data, the terminal 2 suspends transmitting data in the puncturing area or continues transmitting data, and the base station side performs transmission with the terminal 1 through the resources of the puncturing area, so that the base station does not receive data transmitted by the terminal 2 in the puncturing area, and after puncturing is finished, the base station continues receiving data transmitted by the terminal 2;

if the data area of subframe 2 is downlink data, terminal 2 suspends receiving data in the puncturing area, or continues to perform receiving operation, and the base station side performs transmission with terminal 1 through the resources of the puncturing area, so that the base station does not continue to transmit data to terminal 2 in the puncturing area, and after puncturing is finished, the base station continues to transmit data to terminal 2 in subframe 2.

(3) The terminal 1 sends a first signal to a base station on a subframe 1;

the base station needs to transmit the second signal to the terminal 1 in the subframe 2, the subframe 2 is a transmission resource allocated to the terminal 1, and the corresponding position to be fed back is a data region (uplink data or downlink data) of the subframe 2, so the base station or the terminal 1 punctures the subframe 2, and the base station transmits the second signal to the terminal 1 in the puncturing region of the subframe 2. Wherein, if the data is uplink data, the base station punches, and the terminal 1 punches.

(4) The terminal 1 sends a first signal to a base station on a subframe 1;

the base station needs to transmit the second signal to the terminal 1 in the subframe 2, the subframe 2 is a transmission resource allocated to the terminal 2, and the corresponding position to be fed back is a data region (uplink data or downlink data) of the subframe 2, so the base station or the terminal 2 punctures the subframe 2, and the base station transmits the second signal to the terminal 1 in the puncturing region of the subframe 2.

As can be seen from the above example, if the resource for the terminal to transmit or receive the second signal is a resource already allocated to another terminal, the other terminal performs puncturing, and the terminal does not need puncturing.

After the punching, not only the uplink control information but also the downlink control information or the reference signal and the data service can be carried. As shown in fig. 5: the 1 BRU forms a short TTI and the feedback follows the timing of n + 2. The 4 BRUs constitute a long TTI, and the feedback follows the timing of n + 1. The horizontal bar filling part is a long TTI, the data part of the short TTI is uplink data, and the original data (marked by diagonal bars filled with dashed diagonal lines) needs to be knocked off in the horizontal bar filling long TTI, where the knocked off part is used for carrying downlink control information, such as downlink ACK/NACK, paging messages, multi-antenna configuration messages, and other signaling that may be carried by a PDCCH channel or other control channels. The selection of the position of the puncture insertion DC (downlink control) is based on the BRU control channel region above, and is the same as or related to the resource occupation, timing relation, even internal symbol structure and function, etc. configured in the BRU control channel region. The punctured part may also insert reference signals SRS, such as measurement reference signals formed upon request triggering. Or temporarily inserted data services such as seismic information broadcasts, etc.

If the amount of inserted data is large and there is a need for transmission of control information, the entire BSU portion may be punctured in the long subframe to transmit related data and control information. As shown in fig. 6, 1 BRU forms a short TTI. The 4 BRUs constitute a long TTI. The horizontal bar filling part is long TTI, the 2 nd BRU is wholly knocked out in the horizontal bar filling long TTI, and the knocked-out part is used for bearing short TTI.

As an example of the following behavior, when the terminal needs to puncture when demodulating data, the content that can be notified by the base station through signaling may be transmitted, and when the base station uses a robust coding scheme, the terminal may receive data without puncturing.

One of the prerequisites for implementing the puncturing solution is that the terminal needs to know the position or condition of the long and short subframes TTI, regardless of whether puncturing is used for carrying downlink control information or uplink control information. When the long and short sub-frames TTI all belong to the same user, the position or condition of the long and short sub-frames TTI, the base station needs to be configured to the terminal in advance, and the configuration method can adopt a method of system broadcast configuration or configuration in a sub-frame head downlink control area.

The second premise is whether the terminal can perform self-feedback, and when the terminal accesses the system, important information such as whether the terminal supports self-feedback and feedback processing time delay is required to be reported.

The original TTI data segment is punched, and the advantage is that the feedback timing relationship does not need to use a large-space table to agree the timing relationship of the control information feedback in a way similar to the LTE TDD mode. Under the support of the punching method, the feedback control information can be completely fed back according to the timing relation n + k, and each user detects/sends corresponding control signaling in a TTI or a BRU control area according to the TTI configuration. For a short subframe consisting of one BRU, k is the number of BRUs. For a long subframe consisting of multiple BRUs, the number of subframes TTI may be equal to an integer multiple of BRUs.

For the inserted reference signals and data, the insertion mode is more flexible, and the occurrence opportunities of subframes of the same type do not need to be waited.

Example 2

In this embodiment, another multiplexing solution that the long and short subframes TTI belong to the same user is introduced.

A possible solution for the mixture of long and short subframes may also be that the long TTI transmits the control information to be fed back in the short TTI, and needs to be multiplexed with other feedback information of the short TTI. As shown in fig. 7, the long TTI is followed by 4 short TTIs, and according to the feedback timing sequence of the long TTI n +1, the feedback thereof falls into the uplink timeslot of the 4 th short TTI, and needs to be multiplexed with the uplink control information originally assumed by the short TTI.

Example 3

In this embodiment, a solution that the long and short subframes TTI do not belong to the same user is introduced.

For the case that the long and short subframes belong to different users, for example, the short subframe is a low-latency internet of things (uMTC) user, and the long subframe is a mobile user (MBB) covered by a common wide area, the method is consistent with the method that the long and short subframes TTI belong to the same user in the specific puncturing and multiplexing mode. However, since the two users are separated, the terminal capabilities of the two users, such as whether to self-feed or not, cannot be directly transferred, and the obtaining of the prior information is complicated. When the feedback signaling of the uMTC user needs to be carried in the data part of the MBB user by punching, and the terminal capability of the uMTC user cannot be directly transmitted to the MBB user, the feedback signaling needs to be transferred through the base station. The base station informs a user of an uplink, downlink data and/or pilot frequency resource allocation mode in a downlink control region of each subframe, wherein the resource allocation mode refers to which resources can be used for transmitting data or which resources are used for puncturing. Specifically, the DC/UC control regions of which BRUs in which TTIs are signaled are punctured. The terminal can determine different behaviors according to the notified punching area, for example, the terminal which originally performs downlink reception can avoid data reception of the punching area, thereby avoiding demodulation errors; a terminal requiring feedback control information or inserting a reference signal may transmit a relevant signal within a puncturing area.

Similarly, in embodiment 3, there is a case of multiplexing control information, because the control information of two different users is multiplexed, processing manners such as combining and binding cannot be performed, the distinguishing method may adopt code division, and the base station needs to notify the user related information to distinguish the code words.

Based on the same or similar conception with the embodiment, the embodiment of the invention also provides a signal transmission method. Referring to fig. 8, a schematic diagram of another signal transmission method proposed by the present invention is shown.

The signal transmission method comprises the following steps: and the delay time of the feedback control information related to the data is carried in the control information of the current subframe and is dynamically notified to another device. Wherein the feedback time is expressed in multiples of a basic resource unit BRU.

Example 4

In this embodiment, a time delay scheme for dynamically notifying feedback control information is provided.

For example, the DL control information of the downlink data may carry a delay time of feedback control information related to the data, specifically, a value of k in n + k, in the DL control information of the current subframe, and this feedback time is expressed in a multiple form of a BRU, and the feedback may be performed without being fixed to the BRU of n + k by a dynamic notification method, so that the puncturing solution may be avoided. And the eNB flexibly sets the feedback time k of the control information of the UE according to the configuration condition of the long subframe and the short subframe.

Example 5

FDD system multiplexing and punching method

The basic resource unit BRU may also not be limited to TDD mode, i.e. the BRU includes both downlink and uplink regions. In the FDD mode of the new generation, a BRU may be constructed as shown in fig. 9A, which is based on the FDD duplex mode, and only downlink data and downlink control are available at the downlink frequency point, and only uplink data and uplink control are available at the uplink frequency point. The data and control part is in time division multiplexing relation, the downlink is generally controlled before the data, and the uplink is generally controlled after the data.

In the FDD mode, there is also a scenario where long and short subframes TTIs are used in a mixed manner, and the control information related to feedback may also be punctured or multiplexed by using a similar method in the foregoing embodiments. As shown in fig. 9B, the feedback of the downlink short subframe performs puncturing at a position of the BRU uplink control corresponding to the uplink long subframe, and transmits uplink control information.
