Technical Field
The invention relates to a mobile internet technology, in particular to a resource allocation method and a resource allocation device integrating time division duplex and frequency division duplex.
Background
The existing Long Term Evolution (LTE) system and the enhanced Long Term Evolution (LTE-a) system can work based on two systems, one is Frequency Division Duplex (FDD) system, and the other is Time Division Duplex (TDD) system.
In FDD system, downlink transmission and uplink transmission are carried in paired frequency spectrums, that is, two different frequency bands, and downlink transmission and uplink transmission are frequency division duplex, so as to avoid mutual frequency band interference, and fig. 1 is a frame structure diagram corresponding to the existing FDD system. In the TDD scheme, downlink transmission and uplink transmission are carried at the same frequency point, and the downlink transmission and the uplink transmission have the same frequency, time division duplex, so as to avoid mutual time slot interference, and fig. 2 is a frame structure diagram corresponding to the existing TDD scheme.
In order to facilitate scheduling, simplify feedback design, and the like, the FDD and TDD standards maintain the consistency of frame structure design to the greatest extent, for example, a Sub-frame (Sub-frame) structure with equal length is adopted: each subframe is 1ms and comprises two time slots of 0.5 ms; the 10 subframes constitute a Radio Frame (Radio Frame) of 10 ms.
Different from the FDD system, a special subframe is introduced into a frame structure corresponding to the TDD system, and the special subframe is composed of three parts, namely, a Downlink Pilot Time Slot (DwPTS, Downlink Pilot Time Slot), a Guard interval (GP, Guard Period), and an Uplink Pilot Time Slot (UpPTS, Uplink Pilot Time Slot).
Although the FDD and TDD standards keep the consistency of the frame structure design to the greatest extent, the FDD and TDD standards are two different standards, and the business model of a single operator can only be introduced into one of the two standards; in addition, the characteristics of multiple station type layered networking of the future network and the current situation of frequency allocation existing internationally and the like require an operator to simultaneously support a TDD system and an FDD system in the future; therefore, the prior art cannot realize the integration of TDD and FDD, and thus cannot meet the development requirements of future mobile internet services.
Disclosure of Invention
In view of this, the present invention provides a resource allocation method and device for merging tdd and fdd, which can implement merging of tdd and fdd, thereby meeting the development requirements of future mobile internet services.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a resource allocation method for time division duplex and frequency division duplex fusion comprises the following steps:
according to the actual service requirements of the base station and the terminal, dynamically allocating resource blocks for the base station and the terminal based on available two-dimensional time-frequency resources;
and for each allocated resource block, respectively taking one resource block with a preset size as a control domain, and indicating resource allocation information of the next allocated resource block in the control domain.
A resource allocation device for time division duplex and frequency division duplex fusion comprises:
the first processing module is used for performing dynamic resource block allocation for the base station and the terminal based on available two-dimensional time-frequency resources according to the actual service requirements of the base station and the terminal;
and the second processing module is used for taking one resource with a preset size as a control domain for each allocated resource block, and indicating resource allocation information of the next allocated resource block in the control domain.
Therefore, by adopting the scheme of the invention, the base station and the terminal can be dynamically allocated with the resource blocks based on the available two-dimensional time-frequency resources according to the actual service requirements of the base station and the terminal, and one resource with the preset size can be respectively used as a control domain for the resource blocks allocated each time, and the resource allocation information of the resource blocks allocated next time is indicated in the control domain, so that the fusion of time division duplex and frequency division duplex is realized, and the development requirement of the future mobile internet service is further met.

Detailed Description
In the prior art, in order to facilitate resource allocation, user scheduling, and the like, an LTE system and an LTE-a system design resources of two dimensions, namely a time domain and a Frequency domain, where a Frequency domain resource uses a subcarrier as a minimum unit, and a time domain resource uses an Orthogonal Frequency Division Multiplexing (OFDM) symbol as a minimum unit; in addition, in a two-dimensional time-frequency Resource space, Resource Elements (REs) are defined as the minimum time-frequency Resource unit of a physical layer, and one Resource Element occupies one OFDM symbol in a time domain and one subcarrier in a frequency domain.
However, the resource element is a very small resource unit, and is not suitable because too much scheduling instruction and feedback overhead are caused as a resource scheduling unit. Therefore, Resource Blocks (RBs) are defined in the LTE system and the LTE-a system, and each RB is used as a basic time-frequency Resource unit, and occupies one slot (0.5 ms) in the time domain and 12 consecutive subcarriers in the frequency domain. Under the configuration of a conventional cyclic prefix, one resource block occupies 7 OFDM symbols in the time domain, and under the configuration of an extended cyclic prefix, one resource block occupies 6 OFDM symbols in the time domain. Two consecutive resource blocks in the time domain may constitute one resource block Pair (RB Pair).
Fig. 3 is a schematic diagram of a relationship between a resource block and a resource particle in the prior art. As shown in fig. 3, it is assumed that one resource block occupies 7 OFDM symbols in the time domain.
Accordingly, fig. 4 is a flowchart of a TDD and FDD combined resource allocation method according to an embodiment of the present invention. It should be noted that the following expressions of "step 41" and "step 42" are only for convenience of description, and are not used to limit the order of the two. As shown in fig. 4, includes:
step 41: and dynamically allocating resource blocks for the base station and the terminal based on the available two-dimensional time-frequency resources according to the actual service requirements of the base station and the terminal.
In practical application, based on an Orthogonal Frequency Division Multiple Access (OFDMA) mode, the available two-dimensional time-Frequency resources can be flexibly divided into a plurality of dynamically configurable resource blocks on the network side according to the actual service requirements of the base station and the terminal. Fig. 5 is a schematic diagram of resource blocks obtained according to the method of the present invention, as shown in fig. 5, each small rectangle represents a resource block, and the arrow direction represents uplink transmission or downlink transmission.
Specifically, in the service process of the base station and the terminal, the resource blocks can be dynamically allocated to the base station and the terminal according to the actual service requirements of the base station and the terminal, such as whether the base station needs to send data or the terminal needs to send data, the size of the data quantity needing to be sent, and the like, and the resource blocks can be flexibly configured to be uplink transmission or downlink transmission, the size of the resource blocks can be flexibly configured, and the like.
Step 42: and regarding each allocated resource block, respectively taking one resource block with a preset size as a control field, and indicating resource allocation information of the next allocated resource block in the control field.
In the scheme of the invention, the allocation of the resource blocks can be carried on a plurality of available carriers, thereby realizing the resource allocation of cross-Carrier and the like.
Taking the example that the base station and the terminal do not work in the carrier aggregation mode, for each allocated resource block (one) at a time, a block of resource with a predetermined size may be respectively selected at the starting position of the resource block as a control field, and a specific value of the predetermined size may be determined according to actual needs, so as to indicate resource allocation information of the next resource block in the control field. Therefore, for the base station and the terminal, the time-frequency position and the like of the next resource block can be obtained by reading the information in the control domain, and correspondingly, the data is received or sent at the time-frequency position.
The resource allocation information of each resource block includes, but is not limited to, the following:
1) the wireless frequency point and the carrier wave number corresponding to the resource block are numbered;
2) the time sequence number of the resource block;
how to determine the timing number of the resource block is the prior art, and absolute numbers (for example, for the first transmission) and incremental numbers (for example, for the subsequent transmission) are supported;
3) frequency domain location information of the resource block;
the frequency domain location information of the resource block may include one of:
the frequency starting position K of the resource block and the bandwidth K of the resource block;
the difference increment delta K of the frequency starting position of the resource block relative to the frequency starting position of the last resource block and the bandwidth K of the resource block;
4) time domain position information of the resource block;
the time domain location information of the resource block may include one of:
the time starting position L of the resource block and the duration L of the resource block;
the difference increment delta L of the time starting position of the resource block relative to the time starting position of the last resource block and the duration L of the resource block;
the duration L can take a subframe or an OFDM symbol as a unit and supports multi-subframe scheduling in a time domain;
5) the data channel transmission type of the resource block is uplink transmission or downlink transmission.
The above is a description of the case where the base station and the terminal are not operating in the carrier aggregation mode, and the following is a description of the case where the base station and the terminal are operating in the carrier aggregation mode.
When the base station and the terminal operate in the carrier aggregation mode, each allocated resource block may include: the method includes that 1 main carrier resource block and M auxiliary carrier resource blocks are provided, M is a positive integer, namely at least one auxiliary carrier resource block, correspondingly, when resource allocation information of a next allocated resource block is indicated in a control domain, the resource allocation information of the 1 main carrier resource block and the resource allocation information of the M auxiliary carrier resource blocks need to be indicated respectively, and how to indicate the resource allocation information is not limited specifically. At this time, for the following described in the above-mentioned 3) and 4): for each resource block, the last resource block refers to the resource block allocated once before the resource block and corresponding to the same carrier as the resource block.
Fig. 6 is a schematic diagram of a manner of indicating resource allocation information of 1 primary carrier resource block and M secondary carrier resource blocks in a control domain, respectively, according to the present invention. As shown in fig. 6, it is assumed that the resource blocks allocated each time are respectively numbered according to the sequence of the allocation time from first to last, the number of the resource block allocated first is 0, then 1 and 2 …, and so on; then, the resource allocation information of the resource block numbered N +1 may be indicated in the control field of the resource block numbered N, specifically, the resource allocation information of the primary carrier resource block numbered N +1 and the secondary carrier resource block numbered N +1 (assuming that the value of M is 1) may be indicated respectively; the method comprises the following steps that kN represents the frequency starting position of a resource block with the number of N, lN represents the time starting position of the resource block with the number of N, KN represents the bandwidth of the resource block with the number of N, and LN represents the duration of the resource block with the number of N.
In addition, when the base station and the terminal work in a carrier aggregation mode, when the resource blocks allocated for a certain time comprise 1 main carrier resource block and M auxiliary carrier resource blocks, a piece of resource with a preset size can be selected as a control domain at the initial position of the main carrier resource block; or, one resource block is selected from the 1 main carrier resource block and the M auxiliary carrier resource blocks, a resource block with a predetermined size is selected as a control domain at the initial position of the selected resource block, and how to select one resource block from the 1 main carrier resource block and the M auxiliary carrier resource blocks can be determined according to actual needs. Preferably, the former way can be adopted, that is, a block of resources with a predetermined size is selected as the control field at the starting position of the primary carrier resource block.
The base station and the terminal in the scheme of the invention need to support TDD system and FDD system at the same time, and can be dynamically scheduled, namely, the base station and the terminal in the future are all of unified system, and no single TDD system or FDD system exists.
The base station and the terminal can operate on the corresponding resource blocks according to the resource allocation information indicated in the control domain, that is, perform data reception and transmission, and the like.
In addition, for a resource block for which the resource allocation information cannot be indicated, a static resource allocation method may be adopted, and the base station and the terminal operate on the resource block in a default manner.
For example, suppose that the resource blocks allocated for each time are numbered respectively according to the sequence of the allocation time from first to last, the number of the resource block allocated first is 0, then 1 and 2 …, and so on; since the resource block numbered 0 does not have the previous resource block, it is impossible to indicate its resource allocation information, and accordingly, the base station and the terminal can operate on the resource block in a default manner.
Furthermore, in order to avoid the occurrence of uplink and downlink cross interference between two adjacent resource blocks, for the uplink and downlink resource blocks adjacent to each other in the time domain, a Guard Period (Guard Period) with a predetermined size may be reserved between the two adjacent resource blocks, that is, when the transmission types of the data channels of the two adjacent resource blocks in the time domain are uplink transmission and downlink transmission, a Guard Period with a predetermined size is reserved between the two adjacent resource blocks; for the uplink and downlink resource blocks adjacent to each other in the frequency domain, a Guard bandwidth (Guard Band) with a predetermined size may be reserved between the two resource blocks, that is, when the transmission types of the data channels of the two resource blocks adjacent to each other in the frequency domain are uplink transmission and downlink transmission, respectively, a Guard bandwidth with a predetermined size is reserved between the two resource blocks. The specific value of the predetermined size can be determined according to actual needs.
