Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, below lift specific embodiment and, the present invention is described in more detail with reference to accompanying drawing.
For the different delay demand according to the type of service of different terminals adopts different radom heuristic packets, the present invention needs to solve following two problems when the radom heuristic packet is set.
First problem must guarantee that the radom heuristic packet that sends by RACH is short as far as possible.If RACH Preamble among the RACH and RACH message are sent as the radom heuristic packet together, then collision probability is bigger because length is long for the radom heuristic packet of each terminal transmission in the wireless communication system, access channel to wireless communication system disturbs bigger, therefore need send as the radom heuristic packet with RACH Preamble, after wireless communication system obtains the access features resource of RACH of terminal, terminal sends RACH message again, promptly send to insert request, thereby avoid colliding and the interference of the access channel of wireless communication system.
Second problem, must guarantee the access feedback at random fast of wireless communication system, be that the wireless communication system network side is after receiving RACH Preamble and RACH message, as early as possible to the terminal feedback information, to reduce the terminal time delay of access to wireless communication system at random.
In order to solve first problem, RACH Preamble and RACH message separately need be sent, being about to RACH Preamble sends as the radom heuristic packet, RACH message is asked transmission as inserting, thereby reduce the collision probability of the radom heuristic packet of each terminal transmission; In order to solve second problem, RACH Preamble and RACH message need be sent together, be about to RACH Preamble and RACH message and send as the radom heuristic packet together, thereby reduce the time of feeding back.As can be seen, the method that solves these two problems is a contradiction.In addition, because the type of service of different terminals is also different to the demand of access delay at random, therefore the present invention can be according to the type of service of different terminals to the demand of access delay at random, different radom heuristic packets is set, promptly the type of service to the high terminal of delay requirement adopts second radom heuristic packet that problem is set of solution, to the set radom heuristic packet of type of service employing first problem of solution of the not high terminal of delay requirement.
When terminal transmission form was the radom heuristic packet of RACH Preamble+RACH message, Message and Preamble adopted the mode of competition to send, and there is a strong possibility in wireless communication system exists conflict; When terminal transmission form was the radom heuristic packet of RACH Preamble, follow-up Message adopted the mode of scheduling to send, and not having conflict and taking place in wireless communication system.
It is as described below that the present invention is provided with the detailed process of two different radom heuristic packets.
In the wireless communication system network side two kinds of different radom heuristic packets are set, a kind of form of radom heuristic packet is RACH Preamble+RACH message, and the form of another kind of radom heuristic packet is RACH Preamble.These two kinds different radom heuristic packets take the wireless communication system network side joint respectively and go into diverse location in the resource pool, and the radom heuristic packet to the different radom heuristic packet in diverse location carries out demodulation, as shown in Figure 2.
The present invention goes into setting in the resource pool in order to simplify the wireless communication system network side joint, also can form be that to be set to form be that the structure of the RACH Preamble in the radom heuristic packet of RACH Preamble is identical for RACHPreamble in the radom heuristic packet of RACH Preamble+RACH message, in terminal is that RACH Preamble in the radom heuristic packet of RACH Preamble+RACHmessage is when modulating to form, can unify to adopt terminal is the modulator approach that the radom heuristic packet of RACH Preamble carries out to form, guarantees that the wireless communication system network side is used constructed RACH Preamble to be carried out demodulation.Form is that the RACHmessage in the radom heuristic packet of RACH Preamble+RACH message can be bundled on the RACH Preamble when terminal radom heuristic packet is set to a frame according to the rule of setting, and the wireless communication system network side can be carried out demodulation to the RACH message that is bundled in RACH Preamble according to the rule of setting.
The rule of setting can be carried the RACHmessage of binding for carry RACH Preamble on the odd number of the access exploration packet that is set to a frame or even number subframe on corresponding contiguous even number or the odd number subframe.
The present invention can also be that the formatting of the radom heuristic packet of RACH Preamble is the virtual RACH message of RACH Preamble+ with form, data among the wherein virtual RACH message are 0, like this, the form that can guarantee two kinds of different radom heuristic packets is unified in form, certainly, separate timing at wireless communication system, still the diverse location in the access-in resource pond carries out demodulation.
When the wireless communication system initialization, the corresponding relation of the access service classification information (ASC) that RACH is set and different radom heuristic packets, promptly the ASC to the type of service correspondence of the high terminal of delay requirement is the radom heuristic packet of RACH Preamble+RACH message corresponding to form, ASC to the type of service correspondence of the low terminal of delay requirement is the radom heuristic packet of RACHPreamble corresponding to form, and the ratio that guarantees two kinds of different radom heuristic packets is a constant in same section turn-on time at random, this is because if all adopting form is the radom heuristic packet of RACH Preamble+RACH message, above-mentioned first problem can occur.
The method flow diagram of the radom heuristic packet access to wireless communication system that Fig. 3 is different for the present invention adopts, assumed wireless communication system network are the NodeB under the terminal, and concrete steps are:
The present invention can also broadcast setting two kinds of radom heuristic packets can with access slot, access features resource or sub-band etc. be used to identify the information of radom heuristic packet.
After step 301, terminal are received broadcast, determine pairing ASC according to the type of service of terminal, carry out determine the radom heuristic packet initial setting up of ASC correspondence.
Described radom heuristic packet is initially set to the access features resource and the access information that will send according to the radom heuristic data packet format to be added in the radom heuristic packet.
When being RACH Preamble+RACH message for the form of the radom heuristic packet of determining ASC correspondence, terminal as the radom heuristic packet, sends RACH Preamble+RACH message in a RACH burst Burst (RACH Burst);
When being RACH Preamble for the form of the radom heuristic packet of determining ASC correspondence, terminal as the radom heuristic packet, sends RACH Preamble in a RACH Burst.
In the present invention, carry the access features resource among the RACH Preamble, comprise code word, frequency, subband, time slot or these several persons' combination in any; The resource request control signaling that RACH message carried terminal sends.
After step 303, NodeB receive the different radom heuristic packet, carry out the demodulation of different modes.
For form is the radom heuristic packet of RACH Preamble+RACH message, NodeB is except after obtaining the time synchronized correlation peak according to existing related operation according to RACH Preamble, when sending confirmation signal to terminal, RACH message is carried out demodulation, promptly adopt RACH Preamble to carry out channel estimating, to RACH message demodulation, obtain the access information of terminal, insert message to the terminal feedback.
For form is the radom heuristic packet of RACH Preamble, after NodeB obtains the time synchronized correlation peak according to existing related operation according to RACH Preamble, send confirmation signal to terminal, terminal sends the access request that form is RACH message after receiving confirmation signal again, NodeB adopts RACH Preamble to carry out demodulation after the channel estimating to inserting RACH message in the request again, after obtaining the access information of terminal, insert message to the terminal feedback.
The access message that step 305, terminal are fed back according to NodeB continues with NodeB mutual, finishes follow-up complete random access procedure according to prior art.
For adopting form is the terminal of the radom heuristic packet of RACH Preamble+RACH message, if access failure all in the number of times of setting, the number of times of this setting is set according to the requirement of wireless communication system, illustrate that then radom heuristic packet that this terminal sends can cause the interference of wireless communication system access channel, low time delay can not guarantee success access to wireless communication system at random, at this moment can to adopt form be the radom heuristic packet of RACH Preamble to terminal, carries out random access procedure.
In addition when the wireless communication system load increases, form is that the access collision probability of the radom heuristic packet of RACH Preamble+RACHmessage can sharply increase, access delay can increase greatly, therefore adopt the radom heuristic packet of form RACH Preamble+RACH message, preferably can adjust according to the access loading condition of system.When the wireless communication system load is low, as be lower than when equaling set point, the radom heuristic packet keeps original form RACHPreamble+RACH message to send; When the wireless communication system load is high, as being higher than set point, is that the formatting of the radom heuristic packet of RACH Preamble+RACH message sends for RACH Preamble with form.Set point is 1 for the normalization load.
The present invention also can omit the step 304 among Fig. 3, but divides timing in wireless communication system access-in resource pond, gives the ratio of two kinds of set radom heuristic packets with regard to fixed allocation.
The present invention is provided with two kinds of different radom heuristic packets, the process of access to wireless communication system at random of different delay is provided at the type of service of the terminal of different delay demand respectively, thereby can adopts different radom heuristic packets to carry out random access procedure according to the different delay demand of the type of service of different terminals.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
