In order to enable those skilled in the art to better understand the solution of the present invention, below in conjunction in the embodiment of the present invention Attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only The embodiment of a part of the invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people The every other embodiment that member is obtained without making creative work should all belong to the model that the present invention protects It encloses.

Resource allocation provided in an embodiment of the present invention and data transmission method are applied to a kind of wireless communication system.Lower kept man of a noblewoman A simple introduction first is done to the wireless communication system.The wireless communication system can be based on GSM (Global System For Mobile communication, global system for mobile communications) or LTE (Long Term Evolution, long term evolution) Etc. systems improvement, compared with existing GSM or LTE system, the difference is that, the transmission bandwidths of uplink and downlink is different. Described transmission bandwidth and system bandwidth are different concept, and system bandwidth refers to uplink or the total bandwidth of downlink, and is transmitted Bandwidth refers to the bandwidth of the carrier wave of specific carrying signal on frequency domain.Carrier wave can be understood as the radio frequency money of a frequency range Source.

In existing GSM or LTE system, the resource granularity of uplink and downlink is identical, in other words, up-link carrier and descending carrier Bandwidth and time slot all same.And in the wireless communication system described in the present invention, in order to improve covering level, reduce uplink Transmission bandwidth, will a up-link carrier identical with descending carrier bandwidth originally, be divided into multiple subcarriers by frequency domain, each The transmission that a uplink sub-carrier carries out upstream data is used only in user equipment (User Equipment, UE), to reduce Uplink bandwidth can improve the PSD of uplink, and then the uplink covering of lifting system under identical transmission power Range.

In the embodiment of the present invention, the multiple uplink sub-carriers of descending carrier schedulable, in other words, multiple uplink sub-carriers Scheduling information come from the same descending carrier, the sum of the bandwidth of multiple uplink sub-carriers of a descending carrier schedulable, Equal to the bandwidth of the descending carrier.Also, the bandwidth of multiple uplink sub-carriers may be the same or different, to adapt to difference The covering demand of user equipment.Also, the bandwidth of descending carrier is the integral multiple of the bandwidth of each uplink sub-carrier, such as 2 times, Or 3 times or 4 times, or more times.

In wireless communication system, a basic resource unit is can define, which is that one is occupied on frequency domain Fixed bandwidth occupies the signaling bearer unit of certain length in time domain.In uplink and downlink transmission, need to ensure uplink Basic resource unit is identical with the capacity of the basic resource unit of downlink, to carry the signal of same size.In basic resources list On member, the resource unit of higher granularity can also be included, the resource unit of each higher granularity may include multiple basic resources Unit.

In the wireless communication system of the embodiment of the present invention, since the bandwidth of uplink sub-carrier is less than the bandwidth of descending carrier, Capacity in order to ensure the basic resource unit of uplink and downlink is identical, it is necessary to which corresponding extend in uplink sub-carrier provides substantially The length of source unit in the time domain.For example, the bandwidth of a uplink sub-carrier is the half of descending carrier bandwidth, then uplink The time domain length of the basic resource unit of subcarrier, it is necessary to be the two of the time domain length of the basic resource unit of descending carrier Times.In system of the embodiment of the present invention, since the time domain length of the basic resource unit of uplink is changed, then, and higher granularity Resource unit, such as the time domain length of radio frames and subframe can also occur to change accordingly, when uplink sub-carrier bandwidth reduces For descending carrier bandwidth half when, the time domain length of one subframe of uplink accordingly extends one times, such as becomes 2ms from 1ms.

In wireless communication system of the embodiment of the present invention, due to the basic resource unit of uplink sub-carrier frequency domain width and when Length of field is all changed relative to descending carrier, therefore, it can be stated that, the money of the uplink and downlink of the wireless communication system Source granularity is different.Resource granularity can be understood as basic resource unit and its parameter, and parameter includes frequency domain width and time domain length.

Referring to FIG. 1, being the signal of uplink sub-carrier and descending carrier in one embodiment of the invention wireless communication system Figure.Frequency domain bandwidth is longitudinally indicated in Fig. 1, time domain is laterally indicated, it can be seen from the figure that 1 up-link carrier is divided on 4 Row subcarrier UL.Wherein, the bandwidth of the 1st uplink sub-carrier UL1 is that the 1/2, the 2nd uplink of the bandwidth of descending carrier DL carries The bandwidth of wave UL2 is the 1/4 of the bandwidth of descending carrier DL, and the bandwidth of the 3rd uplink sub-carrier UL3 is the bandwidth of descending carrier DL The 1/8, the 4th uplink sub-carrier UL4 bandwidth be also descending carrier DL bandwidth 1/8.Correspondingly, in the identical length of time domain On degree, the time domain length of the resource unit of uplink sub-carrier UL1, UL2, UL3, UL4 is the resource unit of descending carrier respectively 2 times, 4 times, 8 times, 8 times of time domain length.As it can be seen that on identical time domain length, descending carrier DL includes 8 resource units, 1st uplink sub-carrier UL1 includes 4 resource units, and the 2nd uplink sub-carrier UL2 includes 2 resource units, the 3rd uplink Subcarrier UL3 includes 1 resource unit, and the 4th uplink sub-carrier UL4 includes 1 resource unit.

The technical solution that embodiment provides to facilitate the understanding of the present invention is compared with reference to a concrete application example Present invention method is further introduced.

The wireless communication system that present invention method is applied can be based on GSM either LTE or other communications The improvement that system is done, is not herein restricted this.Present invention method can be applied to any required uplink that improves and cover The application scenario of range, for example, can be used for complex building space, alternatively, basement space, alternatively, complicated landform occasion etc..This Concrete application example, for carrying out intelligent meter data recording in basement, the wireless communication system is for being based on GAM systems.

In the application example, the basic resource unit that can define wireless communication system is burst (Burst).One Burst can Including a certain number of such as 148 effective symbols (Symbol), however the needs in order to dispatch convenience and extend, one Burst can include some symbols more, to reach a suitable time domain length；Such as the time domain length of 1Burst can be equal to 156.25*Ts, Ts indicate the time domain length of a symbol.Can define continuous multiple such as 4 Burst is a block (Block).In this application scene example, uplink and downlink use identical Burst structures, still, descending carrier and uplink sub-carrier Burst time domain lengths are different, and the Burst time domain lengths of the uplink sub-carrier of different bandwidth are also different, but each uplink sub-carrier Burst time domain lengths be all descending carrier Burst time domain lengths integral multiple.

For example, the bandwidth of note descending carrier is B_DL, remember that the bandwidth of k-th of uplink sub-carrier isThen,It should be integer.By taking the first uplink sub-carrier that k=1 is indicated as an example, it can rememberContain Justice is：The bandwidth of descending carrier is M1 times of the bandwidth of the first uplink sub-carrier.It is readily appreciated that, correspondingly, the first uplink carries The time domain length of basic resource unit such as Burst in wave should be that the time domain of the basic resource unit Burst in descending carrier is long M1 times of degree；M1 is the integer more than or equal to 2.

In the application example, the resource structures figure of wireless communication system uplink and downlink can be as shown in Figure 4.In the system, substantially Resource unit is Burst, and four continuous Burst form a Block, wherein part Burst is not belonged in Block, and It is dispersed between Block, exists as independent Burst.Such as in Fig. 4, descending carrier includes Burst continuous in time domain Resource, for example, including number be 0-11 12 Block, and number be 0-3 4 independent Burst, wherein number 0-3 Independent Burst be located at number be 2,5,8,11 Block after.It should be noted that all Block of descending carrier connect The number of sequeling and all independent Burst serial numbers；And all Block serial numbers of uplink sub-carrier and all independences Burst serial numbers.
