The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. It will be apparent 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 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 Figure 1, the information transmission method provided in this embodiment of the present invention can be performed by a base station. A base station may be implemented using software and/or hardware. The information transmission method provided in this embodiment includes the following steps.

Step 101: The base station determines the downlink subframes to be 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 the downlink subframe.

The downlink subframe comprises a first subframe 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 a third subframe including at least one physical resource block pair.

Different releases of LTE communication systems are for example Release 8 or 9 LTE communication systems that are primarily deployed for scenarios where homogeneous cells are present (i.e. deployments are primarily for scenarios involving macrocells). system to support different network architectures in current LTE communication systems. The coverage area of a macrocell 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 uniform cell deployment is Frequency selective scheduling gains and multi-user scheduling gains can be met while maintaining a designated cyclic prefix (CP) overhead to resist multipath effects.

Since Rel-10 LTE communication system, especially in Rel-12 LTE communication system which is now standardized and will also be future LTE system, a large number of heterogeneous networks are deployed (i.e., macro-cells and micro-cells). (deployment is performed by combining), and the deployment density of micro-cells within macro-cells is increasing to improve high data rates everywhere at any time. Macrocells are mainly used to maintain coverage, radio resource control and mobility performance. Moreover, much of the future frequency spectrum will be in high frequency bands (such as 3.5 GHz and higher frequency bands), and these high frequency bands can offer greater bandwidth. In mainstream deployment scenarios, inter-frequency deployment is used for macrocells and microcells to reduce interference between macrocells and microcells, and inter-frequency deployments are used for macrocells and microcells for improved frequency spectrum utilization. Co-frequency deployments for microcells may also be considered.

Therefore, in step 101, the base station determines the downlink subframes to be 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 sent by the base station to the UE is control information for scheduling downlink data channels and downlink data conveyed by the downlink data channels, or schedule uplink data channels and control information for setting.

At step 102, the base station transmits first information to the UE by using a downlink subframe. Base stations add data and control information to downlink subframes so that UEs can obtain the corresponding information.

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

The first subframe 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 and at least 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 is N1 first subcarriers and M1 comprising a first Orthogonal Frequency Division Multiplexing (OFDM) symbol, wherein 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 includes N2 second subcarriers and M2 second subcarriers. 2 OFDM symbols, where the spacing between two adjacent second subcarriers in the frequency domain is equal to a set value, and both N2 and M2 are positive integers.

Optionally, N1 equals N2 and M1 equals M2.

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

FIG. 2 is a schematic structural diagram of the first subframe according to an embodiment of the present invention. In the LTE communication system, one radio frame includes 10 subframes, and each subframe has a time domain length of 1 ms. The first sub-frame is a newly introduced sub-frame whose length is also 1 ms and whose time-frequency domain contains multiple sub-physical resource block (RB) pairs. frame, and 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, a subframe of the first type includes 6 sub-physical resource block pairs for the frequency domain width and 15 sub-physical resource block pairs for the time domain length (15 The time domain length of one subframe is occupied by sub-physical resource block pairs), that is, the sub-physical resource block pairs become sub-physical resource block pairs in two dimensions, the time domain and the frequency domain. ing. Each sub-physical resource block pair contains 12 subcarriers in the frequency domain and 14 OFDM symbols in the time domain. The spacing between two adjacent subcarriers in the first type subframe is 250 KHz and the symbol time is 4 microseconds (much less than 66.67 microseconds), while the CP length is 0.67 microseconds. shortened to 76 ns.

Those skilled in the art will know that in the specific implementation process, the frequency domain width and time domain length 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 multiple physical resource block pairs for the frequency domain, and each physical resource block pair occupies the time domain length of the entire subframe. The second subframe, as shown in FIG. 3, includes 100 physical resource block pairs for the frequency domain width, and each physical resource block includes two time slots. In normal CP, one timeslot contains 7 OFDM symbols and the time domain length of each OFDM symbol is 66.67 microseconds. For the extended CP, one timeslot contains 6 symbols and the length of the extended CP is approximately 16 microseconds when the normal CP is approximately 5 microseconds. As shown in FIG. 3, a physical resource block pair (RB Pair) includes time slot 0 and time slot 1, and each time slot includes 7 OFDM symbols. A physical resource block pair occupies 12 OFDM subcarriers in the frequency domain, the spacing between subcarriers 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 a sub-physical resource block pair is the same as in a physical resource block pair. However, the OFDM symbol duration is greatly reduced, the CP length is greatly reduced, and the spacing between subcarriers is greatly increased, making it more suitable for dense microcell deployment in high frequency bands. It can be understood that Specifically, larger Doppler spreads can be resisted by increasing the spacing between subcarriers, and reducing the CP length has little impact on microcell deployment, but reduces overhead and improves OFDM symbol persistence. Reducing the time can increase service delay, which is beneficial for sensitive services, and reducing the OFDM symbol duration is also beneficial for interference coordination and improving network power efficiency. Specifically, compared to the physical resource block structure, the sub-physical resource block pair structure can be used to quickly complete the transmission of the same amount of data. This is because compared to 1 ms, the minimum time scheduling granularity of sub-physical resource block pairs is significantly reduced. In this way the micro-cell can complete more services to enter sleep or closed state and 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. See FIG. 2 for the structure of sub-physical resource block pairs in the third subframe. See 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 and 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 multiplexed by orthogonal frequency division (that is, the physical resource block pair in the third subframe is the first and the sub-physical resource block pair of the third subframe occupies a second frequency band, the first frequency band and the second frequency band do not overlap).

According to the information transmission method provided in this embodiment of the present invention, the base station determines the downlink subframes to be used for transmission of information to the user equipment, and the base station transmits the first information to to the UE, by using a downlink subframe, where the downlink subframe is a first subframe containing at least two sub-physical resource block pairs, the at least two physical resource block pairs; or a third subframe containing at least one sub-physical resource block pair and at least one physical resource block pair, whereby the LTE communication system can accommodate various network architectures and various types of UE can be efficiently and flexibly supported.
