  The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It will be clear that the described embodiments are only some but not all of the embodiments of the present invention. All other embodiments obtained without creative work by persons skilled in the art based on the embodiments of the present invention shall fall within the protection zone of the present invention.

  FIG. 1 is a flowchart of Embodiment 1 of an information transmission method according to the present invention. As shown in FIG. 1, the information transmission method provided in this embodiment of the present invention may be performed by a base station. A base station may be implemented by using software and / or hardware. The information transmission method provided in this embodiment includes the following steps.

  Step 101: The base station determines downlink subframes to be used to transmit the first information to the user equipment UE.

  Step 102: The base station transmits the first information to the UE by using downlink subframes.

  The downlink sub-frame includes a first sub-frame including at least two sub-physical resource block pairs, a second sub-frame including at least two physical resource block pairs, and at least one sub-physical resource block pair And one of the third subframes including at least one physical resource block pair.

  LTE communication systems of different releases, for example, LTE communication of release 8 or 9, where deployment is mainly performed for a scenario where there are uniform cells (that is, deployment is performed for a scenario mainly related to a macro cell) It supports different network architectures in current LTE communication systems such as systems. The coverage area of the macro cell is relatively large, so from a statistical point of view, the amount of UEs served at each time period (or even at each moment) is relatively stable and uniform cell deployment The frequency selective scheduling gain and the multi-user scheduling gain can be met, and a designated cyclic prefix (CP for short) overhead is maintained to combat multipath effects.

  A large number of heterogeneous networks will be deployed in Release 12 LTE communication systems, which are currently standardized, and will be future LTE systems, especially after Release 10 LTE communication systems (ie, macro cells and micro cells With the combination implemented deployment), the deployment density of microcells within the macrocell is increasingly increased so that high data rates can be improved at any point in time. Macro cells are mainly used to maintain coverage, radio resource control and mobility performance. Furthermore, many of the future frequency spectrums are high frequency bands (such as 3.5 GHz and higher), and this high frequency band can provide larger bandwidths. In mainstream deployment scenarios, inter-frequency deployment is used for macro cells and micro cells to reduce interference between macro cells and micro cells, and with macro cells to improve frequency spectrum utilization. The same frequency deployment for microcells may be considered.

  Thus, in step 101, the base station determines the downlink subframes used to transmit the first information to the UE according to the LTE release supported by the base station, the communication system architecture or the LTE release supported by the UE There is a need to. Optionally, the first information transmitted by the base station to the UE schedules control information for scheduling the downlink data channel and downlink data conveyed by the downlink data channel, or uplink data channel And control information for setting.

  In step 102, the base station transmits the first information to the UE by using downlink subframes. The base station adds data and control information to the downlink subframes so that the UE can obtain the corresponding information.

  Specifically, the downlink sub-frame in this embodiment is any one of a first sub-frame, a second sub-frame or a third sub-frame.

  The first sub-frame includes at least two sub-physical resource block pairs, the second sub-frame includes at least two physical resource block pairs, and the third sub-frame includes at least one sub-physical resource block pair It contains one physical resource block pair.

  The length of the time domain occupied by the sub-physical resource block pair is shorter than the length of the time domain occupied by the first subframe, and the sub-physical resource block pair has N1 first subcarriers and M1 Comprising a first Orthogonal Frequency Division Multiplexing (OFDM for short) symbol, where the spacing between two adjacent first subcarriers in the frequency domain is greater than a set value and N1 and Both M1 are positive integers.

  The length of the time domain occupied by the physical resource block pair is equal to the length of the time domain occupied by the second subframe, and the physical resource block pair has N2 second subcarriers and M2 first It contains two OFDM symbols, where the spacing between two adjacent second subcarriers in the frequency domain is equal to the set value, and both N2 and M2 are positive integers.

  Optionally, N1 is equal to N2 and M1 is equal to M2.

  Optionally, the set values listed above may be 15 KHz, 7.5 KHz, etc.

  FIG. 2 is a schematic structural diagram of a first subframe according to an embodiment of the present invention. In the LTE communication system, one radio frame includes 10 subframes, and the time domain length of each subframe is 1 ms. The first subframe is a newly introduced sub whose length is also 1 ms and whose time-frequency domain includes a plurality of sub-physical resource blocks (RBs for short) in pairs. The length of the time domain which is a frame and is occupied by each sub physical resource block pair is shorter than the length of the time domain of one subframe. For example, in FIG. 2, the first type sub-frame includes six sub-physical resource block pairs in the frequency domain width and fifteen sub-physical resource block pairs in the time domain length (15 Sub physical resource block pairs occupy the length of time domain of one subframe), that is, sub physical resource block pairs become sub physical resource block pairs in two dimensions of time domain and frequency domain ing. Each sub-physical resource block pair includes 12 subcarriers in the frequency domain and 14 OFDM symbols in the time domain. The spacing between two adjacent subcarriers of the first type of subframe is 250 KHz and the symbol time is 4 microseconds (much less than 66.67 microseconds) while the CP length is 0. It is reduced to 76 nanoseconds.

  Those skilled in the art will understand that in the specific implementation process, the frequency domain width and time domain length as long as the length of the time domain occupied by each subphysical resource block pair is shorter than the length of the subframe time domain. It will be appreciated that the amount of sub-physical resource block pairs for is not a specific limitation in this embodiment.

  FIG. 3 is a schematic structural diagram of a second subframe according to an embodiment of the present invention. The second subframe contains multiple physical resource block pairs for the frequency domain, and each physical resource block pair occupies the length of the time domain for the entire subframe. As shown in FIG. 3, the second subframe includes 100 physical resource block pairs in the frequency domain width, and each physical resource block includes 2 time slots. In a normal CP, one time slot contains seven OFDM symbols, and the time domain of each OFDM symbol is 66.67 microseconds. In the extended CP, the length of the extended CP is approximately 16 microseconds, where one time slot includes six symbols and the length of the normal CP is approximately 5 microseconds. As shown in FIG. 3, the physical resource block pair (RB Pair) includes time slot 0 and time slot 1, and each time slot includes seven OFDM symbols. The physical resource block pair occupies 12 OFDM subcarriers in the frequency domain, the spacing between the subcarriers is 15 KHz, and the duration of the OFDM symbol is 1 / (15 KHz) = 66.67 microseconds .

  From the embodiment shown in FIG. 2 and FIG. 3, the amount of transportable resource elements in the sub-physical resource block pair (12 subcarriers, 14 OFDM symbols) is the same as in the physical resource block pair However, the duration of the OFDM symbol has been significantly reduced, the CP length has been significantly reduced, and the spacing between subcarriers has been significantly increased, which favors high density microcell deployment in high frequency bands. It will be understood that it becomes. Specifically, increasing the spacing between subcarriers can withstand larger Doppler spreads, and reducing CP length has little impact on microcell deployment but reduces overhead and sustains OFDM symbols Shortening of time may increase service delay, which is beneficial for sensitive services, and shortening of OFDM symbol duration is also beneficial for interference coordination and improvement of network power efficiency. Specifically, in comparison to the structure of physical resource blocks, the structure of sub-physical resource block pairs can be used to quickly complete the transmission of the same amount of data. The reason is that the minimum time schedule setting granularity of the sub physical resource block pair is much smaller than 1 ms. In this way, the microcell may be able to implement inter-cell interference coordination in a time-shared manner, as well as complete more services to enter sleep or close states.

  The third subframe includes at least one sub-physical resource block pair and at least one physical resource block pair. Refer to FIG. 2 for the structure of the subphysical resource block pair in the third subframe. Also, refer to FIG. 3 for the structure of physical resource block pairs in the third subframe.

  Optionally, at least one physical resource block pair of the third subframe occupies the first frequency band, and at least one sub-physical resource block pair of the third subframe occupies the second frequency band The first frequency band and the second frequency band do not overlap.

  Specifically, in the third subframe, the physical resource block pair and the sub-physical resource block pair coexist and are subjected to multiplexing by orthogonal frequency division (ie, the physical resource block pair in the third subframe is the first And the sub-physical resource block pair of the third subframe occupies the second frequency band, and the first frequency band and the second frequency band do not overlap).

  According to the information transmission method provided in this embodiment of the invention, the base station determines the downlink subframes to be used for transmission of the information to the user equipment, and the base station further determines the first information. Transmit to the UE by using a downlink subframe, wherein the downlink subframe is a first subframe including at least two sub-physical resource block pairs, at least two physical resource block pairs The second subframe included, or the third subframe including at least one sub-physical resource block pair and at least one physical resource block pair, whereby the LTE communication system has various network architectures and various types. It is possible to support UE of high efficiency and flexibly.

In step 401, the UE conveys the first information and determines downlink subframes to be transmitted by the base station. Specifically, the UE is a subframe type used to indicate that the downlink subframe transmitted by the base station is a first subframe, a second subframe or a third subframe Receive instructions.

  FIG. 5 is a flow chart of Embodiment 1 of an information transmission and reception method according to an embodiment of the present invention. In this embodiment, the information transmission and reception method of the present invention will be described in detail based on the embodiments shown in FIGS. 1 to 4.

  Step 501: The base station determines downlink subframes to be used for transmitting the first information to the user equipment UE.

  Step 503: A subframe type indication used by the UE to indicate that the downlink subframe is a first subframe, a second subframe or a third subframe transmitted by the base station Receive

  Step 504: The base station transmits the first information to the UE by using downlink subframes.

  Step 505: The UE receives the first information by using downlink subframes.

  In this embodiment, step 501 is similar to step 101 and is not described in detail again in this embodiment herein.

  In steps 502 and 503, the base station transmits a subframe type indication to the UE, and the UE indicates that the downlink subframe is the first subframe, the second subframe or the third subframe Receive the subframe type indication that is used to Those skilled in the art will understand that in the specific implementation process, the base station and the UE pre-configure the base station and the UE, and the designated subframe structure of the first subframe, the second subframe or the third subframe. It can be appreciated that it can be pre-configured to be saved. When the base station transmits a subframe type indication to the UE, the UE specifically follows the subframe type indication whether the subframe is a first subframe or a second subframe or a third It determines whether it is a subframe and then receives the information transmitted by the base station according to the structure of that subframe in the corresponding subframe.

Optionally, if the downlink subframe is a third subframe, then the method provided in this embodiment prior to step 504 is:

The link data channel may be collectively referred to as a data channel. Those skilled in the art will appreciate that, for control information, the base station may transmit control information in the search space, and the user equipment may obtain designated control information from the search space in a blind detection manner.

When downlink subframes transmitted by the base station are received according to the rate matching information, not all of the first time-frequency resources in the downlink subframe are detected, but the first time-frequency. Some of the resources are neither detected nor received (ie some of the first time-frequency resources are skipped). The first time-frequency resource skipped by the UE may specifically be the first time-frequency resource not supported by the LTE release supported by the UE, and also this first time-- The downlink subframes corresponding to frequency resources are paging subframes or synchronization signal transmission subframes.
