Description

A kind of GP length determination, upstream data packet transmission method and device

Technical field

The present invention relates to communication technical field, more particularly to a kind of determination of GP length, upstream data packet transmission method and device.

IoT (Internet of things, Internet of Things) is " the connected internet of thing thing ".It extend to the user terminal of internet between any article and article, enters row information and exchanges and communicate.Such communication mode is also referred to as MTC (Machine type communications, machine type communication), and the user endpoints of communication are referred to as MTC device.Typical Internet of Things, which is applied, includes intelligent meter data recording, smart home etc..

In cellular network, due to UE (User Equipment, user equipment) apart from the far and near different of base station, therefore different propagation delay times can be undergone in transmitting procedure, this results in the time irreversibility that the uplink transmission data bag from different UE reaches base station, dislocation on this arrival time is likely to result in colliding between the uplink transmission data bag from different UE, influences receptivity.The distance difference of two UE and base station is bigger, then the region that may be collided is bigger, and performance more deteriorates.For example, as shown in Figure 1, slot therein represents time slot, scheduling (plan) UE1 (i.e. the plan duration of user equipment 1 in Fig. 1) represents that base station was assumed without the upstream data bag time that UE1 transmissions are received in the case of transmission delay, scheduling UE2 (i.e. the plan duration of user equipment 2 in Fig. 1) represent that base station was assumed without the upstream data bag time that UE2 transmissions are received in the case of transmission delay, it can be seen that, UE1 and UE2 causes their uplink to experienced different propagation delay times (being represented respectively by the d1 and d2 in Fig. 1) to the different distance of base station, so as to cause UE1 and UE2 uplink to there occurs collision (i.e. the common factor part of two upstream data bags in Fig. 1).

In the prior art, in order to avoid this collision as far as possible, in LTE (Long Term Evolution, Long Term Evolution) etc. in cellular network, the method generally used is that base station configures a uplink transmission time lead (timing advance, TA) for each UE, and the information of configuration is sent respectively to each UE by base station again afterwards, so the time-division for receiving the packet that each UE is sent is opened as far as possible, it is to avoid collision is produced.So And, collocating uplink transmission time lead needs relative complex random access procedure, while being also required to base station is continually updated to the uplink transmission time leads of different UE configurations to adapt to the change of environment, and implementation complexity is higher.Moreover, for for Internet of Things M2M (Machine-To-Machine, Machine To Machine) system, in most cases, business packet all very littles of transmission, TA mechanism can be introduced than larger signaling consumption, waste Internet resources.

In addition, the terms " system " and " network " are often used interchangeably herein.The terms "and/or", only a kind of incidence relation for describing affiliated partner, represents there may be three kinds of relations, for example, A and/or B, can be represented：Individualism A, while there is A and B, these three situations of individualism B.In addition, character "/" herein, unless otherwise specified, it is one to typically represent forward-backward correlation object Plant the relation of "or".

On the whole, the embodiment of the present invention includes two kinds of GP (Guard Period, guard time) length determination modes altogether.

The first GP length determination mode：GP length is determined by base station；

Second of GP length determination mode：Base station and MTC device use same method, determine a GP length, and, because the method used is identical, therefore the GP length that base station and MTC device are determined is identical.Certainly, in second of GP length determination mode, the determination method that base station and MTC device are used and determination method that base station in first way is used can be with identical, or can also be different.

Two kinds of GP length determination modes in the embodiment of the present invention are described in further detail with reference to Figure of description.

Fig. 2 is referred to, the embodiment of the present invention provides a kind of GP length determining methods, the detailed process of the first GP length determination mode in as invention described above embodiment described by Fig. 2 embodiments.The main flow of methods described is described as follows.

Step 201：Base station determines the first GP length according to the configuration information of all MTC devices in the base station range.

In the embodiment of the present invention, the configuration information of MTC device is referred to as the schedule information of MTC device, is by base station control and is adjusted, thus is knowable in advance for base station.

Optionally, in the embodiment of the present invention, the configuration information can include：At least one of symbolic number that the upstream data bag that the time span and MTC device that distribution situation, the MTC device of all MTC devices in the base station range send uplink symbol are sent is included.

Wherein, the distribution situation of MTC device, the physical space distribution for all MTC devices being primarily referred to as in the base station range.For example, if all MTC devices and the mutual difference of the distance between the base station in the base station range are smaller, then the base station can make the first GP length shorter, because if if the mutual difference of the distance between MTC device and the base station is smaller, time delay difference each other is just smaller, required GP length is naturally also just smaller, saves system resource.

For the time span that MTC device sends uplink symbol, if MTC device transmission is upper The length of row symbol is longer, then the upstream data bag transmitted by the MTC device is stronger for the tolerance level of collision, then the base station can make the first GP length shorter, saves system resource.

For the symbolic number that the upstream data bag (burst) that MTC device is sent is included, it is similar with the Consideration that MTC device sends the time span of uplink symbol, the symbolic number that the upstream data bag that i.e. MTC device is sent is included is more, upstream data bag then transmitted by the MTC device is stronger for the tolerance level of collision, then the base station can make the first GP length shorter, save system resource.

The base station can determine the first GP length according to one kind above or any several factors.To according to more than several factors determine the first GP length, then need to consider the first GP length drawn after various factors.

The GP length that base station described in the embodiment of the present invention is determined according to the configuration information of all MTC devices in the base station range, so that the GP length determined more tallies with the actual situation, also it can ensure that the GP length determined is relatively reasonable as far as possible, it is to avoid the waste of resource.

Step 202：The first GP length is sent to all MTC devices in the base station range by the base station；Wherein, the first GP length is for indicating that the MTC device for receiving the first GP length does not send the period of any upstream data bag.

Specifically, the first GP length is used for：All MTC devices in the base station range carry the first GP length when sending upstream data bag, and do not send any upstream data bag within the period indicated by the first GP length.

In this embodiment, all MTC devices in the base station range can use same GP length (i.e. described first GP length) to send upstream data bag.

Optionally, in the embodiment of the present invention, the first GP length is sent to all MTC devices in the base station range by the base station, including：

The first GP length is sent respectively to all MTC devices in the base station range by static signaling or semi-static signaling by the base station.

In the embodiment of the present invention, it is substantially and remains static in view of the MTC device in arrowband M2M systems, even if or have movement, its mobility is also very limited, therefore, the uplink time delay distribution of MTC device, which can consider, in the system dynamically to change very much over time, therefore can lead to The signaling or semi-static signaling of relative quiescent is crossed to send the first GP length.For example, semi-static signaling can refer to system broadcast message or high-level signaling.Seldom additional signaling overhead so can be only introduced, system resource is saved.

Certainly, in actual application, the base station can according to circumstances determine whether to the GP length for each MTC device configuration being updated in the base station range.If desired update, then can repeat each step of Fig. 2 flows, new GP length is then attached in upstream data bag to be sent by MTC device after new GP length is received.GP length when is specifically updated, is determined by base station, also relevant with factors such as the specific algorithms that is set in base station, the present invention is not restricted.

Wrapped specifically, the first GP length is attached to upstream data by MTC device, there can be three kinds of different adhering modes, please respectively referring to Fig. 3 A, Fig. 3 B and Fig. 3 C.

Represented in Fig. 3 A, the first GP length has been attached to the front end of upstream data bag by MTC device, i.e., described MTC device will retransmit upstream data bag after the period indicated by the first GP length.

Represented in Fig. 3 B, the first GP length has been attached to the rear end of upstream data bag by MTC device, i.e., described MTC device will wait the period indicated by the first GP length, next upstream data bag is retransmited afterwards after upstream data bag is sent.

What is represented in Fig. 3 C is, the first GP length is divided into two parts by MTC device, and this two parts is respectively attached to the front-end and back-end of upstream data bag, i.e. described MTC device will send the upstream data bag after the period indicated by the GP length that the front end of upstream data bag is adhered to, and next packet is retransmited after the period indicated by the GP length that the rear end for waiting the upstream data bag again adheres to is needed afterwards.In this case, the first GP length can be equally assigned into two parts by MTC device, i.e., shown in Fig. 3 C, or unequal can also be distributed, and can specifically be determined according to actual conditions.

Adhering mode in the embodiment of the present invention has a variety of, and MTC device can be selected arbitrarily, and mode is more flexible.

In order to illustrate the complete procedure of the GP determination modes of the first in the embodiment of the present invention, Fig. 4 is referred to, is the interaction diagrams of the first GP determination mode in the embodiment of the present invention.

Step 1：Base station is according to the configuration informations of all MTC devices in the base station range, really The fixed first GP length.Specific determination mode is as shown in Fig. 2 flows.

Step 2：The first GP length is sent to all MTC devices in the base station range by the base station.

Step 3：MTC device receives the first GP length.Wherein, the MTC device is any MTC device in own base station coverage.

Step 4：The first GP length is attached in upstream data bag by the MTC device.

Step 5：The MTC device sends the upstream data bag to the base station.Wherein, it is attached with the first GP length in the upstream data bag.

Fig. 5 is referred to, based on same inventive concept, the embodiment of the present invention provides a kind of upstream data packet transmission method, second of GP length determination mode in as invention described above embodiment described by Fig. 5 embodiments.It is being described above, under second of GP length determination mode, base station and MTC device can use identical method, is determining GP length, and described by Fig. 5 embodiments is being process that wherein MTC device determines GP length.The main flow of methods described is described as follows.

For MTC device, the configuration information of MTC device can just include：The time span for the uplink symbol that MTC device is sent, and/or, the symbolic number that the upstream data bag that MTC device is sent is included.

For the time span for the uplink symbol that MTC device is sent, if the length for the uplink symbol that MTC device is sent is longer, upstream data bag then transmitted by the MTC device is stronger for the tolerance level of collision, then the MTC device can make the first GP length shorter, saves system resource.

For the symbolic number that the upstream data bag that MTC device is sent is included, it is similar with the Consideration that MTC device sends the time span of uplink symbol, the symbolic number that the upstream data bag that i.e. MTC device is sent is included is more, upstream data bag then transmitted by the MTC device is stronger for the tolerance level of collision, then the MTC device can make the first GP length shorter, save system resource.

Optionally, in the embodiment of the present invention, according to the configuration information of the MTC device, the first GP length is determined, including：

The MTC device is according to the configuration information of the MTC device, and the first corresponding relation between configuration information and GP length according to the MTC device prestored, determines the first GP length Degree.

Specifically, the first GP length is attached in upstream data bag by MTC device, there can be three kinds of different addition manners, have been described, seldom repeat herein in Fig. 3 A, Fig. 3 B and Fig. 3 C.

Fig. 6 is referred to, based on same inventive concept, the embodiment of the present invention provides another GP length determining methods.Had been introduced in two kinds of GP length determination modes in introducing the embodiment of the present invention, under second of GP length determination mode, base station and MTC device can use identical method, determine GP length, described by Fig. 5 embodiments is the process that wherein MTC device determines GP length, and described by Fig. 6 embodiments is exactly that wherein base station uses the process of GP length of being determined with MTC device identical method.The main flow of methods described is described as follows.

Step 601：Base station obtains the configuration information of MTC device；

Step 602：The base station determines the first GP length according to the configuration information of the MTC device；Wherein, the first GP length is for indicating that the MTC device does not send the period of any upstream data bag.

Include multiple MTC devices in the base station range, Fig. 6 embodiments are simply to determination process of the base station for the GP length of any of which MTC device, and for all MTC devices in the base station range, the processing procedure of the base station is all similar.

Because base station and MTC device will determine GP length, and the GP length determined is identical, therefore base station need not be sent to MTC device after GP length is determined.

Optionally, in the embodiment of the present invention, the configuration information includes the time span that institute's MTC device sends uplink symbol, and/or, the symbolic number that the upstream data bag of the MTC device transmission is included.
