  The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. It will be apparent that the described embodiments are only a part and not all of the embodiments of the present invention. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative work shall fall within the protection scope 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 executed 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 a downlink subframe used for transmitting the first information to the user equipment UE.

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

  The downlink subframe includes a first subframe including at least two subphysical resource block pairs, a second subframe including at least two physical resource block pairs, and at least one subphysical resource block pair. And a third subframe including at least one physical resource block pair.

  Different releases of LTE communication systems, for example, release 8 or 9 LTE communications that are primarily deployed for scenarios where there is a uniform cell (ie, deployment is performed for scenarios that are primarily associated with macrocells). 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 in each time period (or even at each instant) is relatively stable, and there is a uniform cell deployment. The frequency selection scheduling gain and the multi-user scheduling gain can be met, and a specified cyclic prefix (CP for short) overhead is maintained against multipath effects.

  Since the Release 10 LTE communication system, in particular, the Release 12 LTE communication system, which has been standardized at present and will become the future LTE system, a large number of heterogeneous networks are deployed (ie, macrocells and microcells). In combination, deployment is performed), and the deployment density of microcells within a macrocell is increased so that high data rates are improved everywhere at any given time. Macrocells are mainly used to maintain coverage, radio resource control and mobility performance. Further, most of the future frequency spectrum is a high frequency band (such as 3.5 GHz and higher frequency bands), and this high frequency band can provide a larger bandwidth. In mainstream deployment scenarios, inter-frequency deployment is used for macrocells and microcells to reduce interference between macrocells and microcells, and macrocell and microcells are used to improve frequency spectrum utilization. The same frequency deployment for the microcell may be considered.

  Accordingly, in step 101, the base station determines a downlink subframe used for transmitting 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 is scheduling control data for scheduling the downlink data channel and downlink data transmitted by the downlink data channel, or uplink data channel. Control information for setting.

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

  Specifically, the downlink subframe in this embodiment is any one of a first subframe, a second subframe, and a third subframe.

  The first subframe includes at least two subphysical resource block pairs, the second subframe includes at least two physical resource block pairs, and the third subframe includes at least one subphysical resource block pair and at least One physical resource block pair is included.

  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 A first orthogonal frequency division multiplexing (OFDM for short) symbol, wherein an interval 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 subcarriers. 2 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 previously set values 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 block (RB) pairs. The time domain length occupied by each sub-physical resource block pair is shorter than the time domain length of one subframe. For example, in FIG. 2, the first type of subframe includes 6 sub-physical resource block pairs for frequency domain width and 15 sub-physical resource block pairs for time domain length (15 The time domain length of one subframe is occupied by one sub-physical resource block pair), that is, the sub-physical resource block pair is a sub-physical resource block pair in two dimensions, 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 subframe is 250 KHz, and the symbol time is 4 microseconds (much smaller than 66.67 microseconds) while the CP length is 0. Reduced to 76 nanoseconds.

  Those skilled in the art will understand that in a specific implementation process, the frequency domain width and the time domain length as long as the length of the time domain occupied by each sub-physical resource block pair is shorter than the time domain length of the subframe. 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 includes a plurality of physical resource block pairs for the frequency domain, and each physical resource block pair occupies the time domain length of the entire subframe. As shown in FIG. 3, the second subframe includes 100 physical resource block pairs with respect to the frequency domain width, and each physical resource block includes two time slots. In a normal CP, one time slot includes 7 OFDM symbols, and the time domain length of each OFDM symbol is 66.67 microseconds. In the extended CP, when one time slot includes 6 symbols and the normal CP length is approximately 5 microseconds, the extended CP length is approximately 16 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 subcarrier spacing is 15 KHz, and the OFDM symbol duration is 1 / (15 KHz) = 66.67 microseconds. .

  From the embodiments shown in FIGS. 2 and 3, the amount of transportable resource elements (12 subcarriers, 14 OFDM symbols) in the sub-physical resource block pair is the same as in the physical resource block pair. Yes, the OFDM symbol duration is significantly reduced, the CP length is greatly reduced, and the spacing between subcarriers is greatly increased, which is better for high density microcell deployments in high frequency bands I understand that Specifically, the increase in spacing between subcarriers can resist larger Doppler spreads, and the reduction in CP length has little impact on microcell deployment, but the overhead is reduced and the OFDM symbol persists. Shortening the time may increase service delay, which is beneficial for sensitive services, and shortening the OFDM symbol duration is also beneficial for interference coordination and improving network power efficiency. Specifically, compared 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. This is because the minimum time scheduling granularity of the sub physical resource block pair is much smaller than 1 ms. In this way, the microcell can complete more services to enter a sleep state or a closed state and can implement inter-cell interference coordination in a time division manner.

  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 sub-physical resource block pair in the third subframe. For the structure of the physical resource block pair in the third subframe, refer to FIG.

However, the first frequency band and the second frequency band do not overlap.

  Specifically, in the third subframe, the physical resource block pair and the subphysical resource block pair coexist and undergo multiplexing by orthogonal frequency division (that is, the physical resource block pair of the third subframe is the first subframe). 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).

  FIG. 5 is a flowchart 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 embodiment shown in FIGS.

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

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

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

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

  In step 502 and step 503, the base station sends 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. Receiving a subframe type indication to be used. A person skilled in the art knows that in a specific implementation process, the base station and the UE pre-assign the base station and the UE to the designated subframe structure of the first subframe, the second subframe, or the third subframe. It will be appreciated that it can be pre-configured for storage. When the base station transmits a subframe type indication to the UE, the UE specifically specifies the first subframe, the second subframe, or the third subframe according to the subframe type indication. Determine whether it is a subframe and then receive information transmitted by the base station in the corresponding subframe according to the structure of that subframe.

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

  In a specific implementation process, a base station transmits a sub-physical resource block pair and a physical resource block pair by frequency division multiplexing, and a UE receives a reference signal having the same configuration on a frequency band. For example, the UE receives a reference signal used for measurement, such as a cell-specific reference signal CRS or a channel state information-reference signal CSI-RS, on the frequency band of the physical resource block pair, and the frequency of the sub physical resource block pair Receive broadcast signals on the band, which simplifies the measurement step and eliminates the need for the UE to separately receive reference signals having different configurations in the two frequency bands.

  In addition, physical resource block pairs and sub-physical resource block pairs are subject to multiplexing in the carrier or frequency division multiplexing within the same subframe, thereby improving flexibility, such as supporting different service types Is possible.

  Alternatively, the control information for scheduling the uplink data channel includes an uplink data channel resource allocation instruction, the uplink data channel resource allocation instruction being in the uplink subframe and Used to point out the location of the physical resource block pair assigned to the UE and the amount of the physical resource block pair, or the resource allocation indication of this uplink data channel is in the uplink subframe and the UE Is used to point out the location of the sub-physical resource block pair allocated to and the amount of the sub-physical resource block pair.

  Specifically, the control information for scheduling the downlink data channel and the control information for scheduling the uplink data channel may be collectively referred to as control information. The link data channel may be collectively referred to as a data channel. One skilled in the art will understand that for control information, the base station may transmit the control information in the search space, and the user equipment obtains the specified control information from the search space in a blind detection manner.

In addition, the control information for scheduling the downlink data channel further includes a modulation / coding scheme used to indicate the transport block size of the downlink data channel, or schedule the uplink data channel The control information for performing further includes a modulation / coding scheme used to indicate the transport block size of the uplink data channel.

  Optionally, the control information further includes a modulation / coding scheme, and the resource allocation indication is used to point to a physical resource block pair location that is in the downlink subframe and allocated to the UE. The UE determines the transport block size of the data channel according to the modulation / coding scheme and the amount of the physical resource block pair transmitted at the location of the physical resource block pair, and the downlink according to the transport block size. Data reception or uplink data transmission is performed.

The downlink subframe corresponding to the first time-frequency resource is a paging subframe or a synchronization signal transmission subframe. Specifically, the base station transmits rate matching information to the UE by using layer 1 signaling or layer 2 signaling.

  In step 602, the base station determines a downlink subframe according to the rate matching information and transmits the downlink subframe to the user equipment. The downlink subframe includes at least two subframes.
