Embodiment

According to description above, the detection of the PRACH bust this in Long Term Evolution-senior (LTE-A) application scenarios can based on following three kinds of schemes:

It should be noted that, PRACH resources employment methods and PRACH re-transmission policy send configuration information by base station 2 and inform subscriber equipment 1.And base station 2 involved herein sends to the PRACH resources employment methods comprised in the configuration information of subscriber equipment 1 only to refer to the operable upstream components carrier wave being configured with PRACH resource of subscriber equipment 1.

Below with reference to accompanying drawing, the PRACH bust this detection under above-mentioned three kinds of schemes is described respectively.

Scheme one: multiple upstream components carrier wave is all configured with PRACH resource, and PRACH retransmits and can only carry out on that upstream components carrier wave carrying out PRACH transmission before.

Fig. 1 show according to an embodiment of the invention in the subscriber equipment of the wireless communication system based on carrier aggregation technology for detecting the method flow diagram of PRACH bust this.

With reference to Fig. 1, first in step s 11, subscriber equipment 1 receives the configuration information from base station 2.

In the present embodiment, according to this configuration information, subscriber equipment 1 knows that base station 2 is all configured with PRACH resource on multiple upstream components carrier wave and PRACH retransmits and can only carry out on the upstream components carrier wave carrying out PRACH transmission before.

So in step s 12, subscriber equipment 1 is configured with on the upstream components carrier wave of PRACH resource at one that has selected and carries out PRACH transmission.

In one embodiment, subscriber equipment 1 can select a upstream components carrier wave to carry out PRACH transmission randomly from the upstream components carrier wave of the multiple PRACH of being configured with resource.

In another embodiment, subscriber equipment 1 also can select a upstream components carrier wave to carry out PRACH transmission according to pre-defined rule from the upstream components carrier wave of the multiple PRACH of being configured with resource.Such as, subscriber equipment 1 can select a component carrier that can provide PRACH transmission opportunity the earliest.

Certainly, In yet another embodiment, subscriber equipment 1 also can according to the instruction of base station 2, and the upstream components carrier wave being configured with PRACH resource of its instruction carries out PRACH transmission.

If this time PRACH transmission success on this upstream components carrier wave, so, in step s 13, the PRACH bust this information of the upstream components carrier wave of all PRACH bust thiss that MAC layer is registered is removed by subscriber equipment 1.

Certainly, in the starting stage of PRACH transmission, also do not have the upstream components carrier wave of PRACH bust this, therefore, step S13 does not need to perform yet.

If this time PRACH bust this on this upstream components carrier wave, so, in step S14, subscriber equipment 1 adds 1 to the PRACH the number of transmissions on this upstream components carrier wave, and judges whether this PRACH the number of transmissions exceedes predetermined threshold.

If the PRACH the number of transmissions on this upstream components carrier wave does not exceed predetermined threshold, so, enter step S15, subscriber equipment 1 continues to carry out PRACH re-transmission on this upstream components carrier wave, and returns above-mentioned steps S13 or S14.

If the PRACH the number of transmissions on this upstream components carrier wave exceedes predetermined threshold, so, enter step S16, the PRACH bust this on this upstream components carrier wave determined by subscriber equipment 1, and from the upstream components carrier wave of the multiple PRACH of being configured with resources of the remaining PRACH of not having bust this, select a upstream components carrier wave to carry out PRACH retransmission, and return above-mentioned steps S13 or S14 until this subscriber equipment 1 is determined in all PRACH transmission be configured with on the upstream components carrier wave of PRACH resource all failed.

If all failed in all PRACH transmission be configured with on the upstream components carrier wave of PRACH resource, so, enter step S17, subscriber equipment 1 is from MAC (MediaAccessControl, medium education) layer sends the first notification message to RRC (RadioResourceControl, wireless heterogeneous networks) layer.

Wherein, this first notification message is all failed for notifying in all PRACH transmission be configured with on the upstream components carrier wave of PRACH resource.

When subscriber equipment 1 sends the first notification message to rrc layer after notifying that all PRACH transmission be configured with the upstream components carrier wave of PRACH resource are all failed from MAC layer, optionally, subscriber equipment 1 can reselect community and reconnect.

It should be noted that, how to carry out reconnecting (re-connection) about subscriber equipment 1 and belong to prior art, for simplicity's sake, therefore not to repeat here.

In order to avoid the failure of uplink communication as much as possible, in one embodiment, when subscriber equipment 1 is determined after the PRACH bust this on this upstream components carrier wave in above-mentioned steps S16, this subscriber equipment 1 can send second notification message to base station 2 by RRC or MAC control element, and this second notification message is for the PRACH bust this of signals base 2 subscriber equipmenies 1 on this upstream components carrier wave.

If also have other to be in the upstream components carrier wave of state of activation, so base station 2 can be transmitted for PRACH for subscriber equipment 1 one or more upstream components carrier wave of reallocating after receiving this second notification message.

In another embodiment, when subscriber equipment 1 is determined after the PRACH bust this on this upstream components carrier wave, this upstream components carrier wave notifying user equipment 1 can be removed in base station 2, like this, again would not attempt PRACH transmission after subscriber equipment 1 on this upstream components carrier wave.

Scheme two: multiple upstream components carrier wave is all configured with PRACH resource, and PRACH retransmits and can carry out on the upstream components carrier wave that any one is configured with PRACH resource.

Fig. 2 show according to another embodiment of the invention in the subscriber equipment of the wireless communication system based on carrier aggregation technology for detecting the method flow diagram of PRACH bust this.

With reference to Fig. 2, first in the step s 21, subscriber equipment 1 receives the configuration information from base station 2.

In the present embodiment, according to this configuration information, subscriber equipment 1 knows that base station 2 is all configured with PRACH resource on multiple upstream components carrier wave and PRACH retransmits and can carry out on the upstream components carrier wave that any one is configured with PRACH resource.

So in step S22, subscriber equipment 1 is configured with on the upstream components carrier wave of PRACH resource at one that has selected and carries out PRACH transmission.

If this time PRACH transmission success on this upstream components carrier wave, so, in step S23, the PRACH bust this information of the upstream components carrier wave of all PRACH bust thiss that MAC layer is registered is removed by subscriber equipment 1.

Certainly, in the starting stage of PRACH transmission, also do not have the upstream components carrier wave of PRACH bust this, therefore, step S23 does not need to perform yet.

If this time PRACH bust this on this upstream components carrier wave, so, in step s 24 which, subscriber equipment 1 adds 1 to the PRACH the number of transmissions on this upstream components carrier wave, and judges whether this PRACH the number of transmissions exceedes predetermined threshold.

If the PRACH the number of transmissions on this upstream components carrier wave does not exceed predetermined threshold, so, enter step S25, select a upstream components carrier wave to carry out PRACH re-transmission in the upstream components carrier wave of the subscriber equipment 1 never multiple PRACH of being configured with resources of PRACH bust this, and return above-mentioned steps S23 or S24.

In one embodiment, subscriber equipment 1 can select a upstream components carrier wave to carry out PRACH re-transmission in the upstream components carrier wave of the never multiple PRACH of being configured with resources of PRACH bust this randomly.

In another embodiment, subscriber equipment 1 also can select PRACH transmission time slot upstream components carrier wave the earliest to carry out PRACH re-transmission in the upstream components carrier wave of the never multiple PRACH of being configured with resources of PRACH bust this.

It should be noted that, in step s 25, what subscriber equipment 1 was selected can be for carrying out the upstream components carrier wave of PRACH re-transmission and transmit identical upstream components carrier wave for PRACH before, also can be different.

If the PRACH the number of transmissions on this upstream components carrier wave exceedes predetermined threshold, so, enter step S26, the PRACH bust this on this upstream components carrier wave determined by subscriber equipment 1, and from the upstream components carrier wave of the multiple PRACH of being configured with resources of the remaining PRACH of not having bust this, select a upstream components carrier wave to carry out PRACH re-transmission, and return above-mentioned steps S23 or S24 until determine in all PRACH transmission be configured with on the upstream components carrier wave of PRACH resource all failed.

If all failed in all PRACH transmission be configured with on the upstream components carrier wave of PRACH resource, so, enter step S27, subscriber equipment 1 is from MAC (MediaAccessControl, medium education) layer sends the first notification message to RRC (RadioResourceControl, wireless heterogeneous networks) layer.

In one embodiment, a PRACH is arranged to the upstream components carrier wave of each PRACH of being configured with resource and transmits timing, this PRACH transmits when timing carries out PRACH transmission from first time on the upstream components carrier wave of each PRACH of being configured with resource.

So, in step S24 ', if this time PRACH bust this on this upstream components carrier wave, so subscriber equipment 1 adds 1 to the PRACH the number of transmissions on this upstream components carrier wave, and judge whether the PRACH the number of transmissions on this upstream components carrier wave exceedes predetermined threshold, and judge whether the PRACH transmission timing on this upstream components carrier wave exceedes pre-specified time.

In step S25 ', if the PRACH the number of transmissions on this upstream components carrier wave does not exceed predetermined threshold, and the PRACH on this upstream components carrier wave transmits timing does not exceed pre-specified time, so, select a upstream components carrier wave to carry out PRACH transmission in the upstream components carrier wave of the subscriber equipment 1 never multiple PRACH of being configured with resources of PRACH bust this, and return above-mentioned steps S23 or S24 '.

If the PRACH the number of transmissions on this upstream components carrier wave does not exceed predetermined threshold, and the PRACH on this upstream components carrier wave transmits timing exceedes pre-specified time, so, subscriber equipment 1 resets to the PRACH the number of transmissions on this upstream components carrier wave, and in the upstream components carrier wave of the multiple PRACH of being configured with resources of never PRACH bust this, select a upstream components carrier wave to carry out PRACH transmission, and return above-mentioned steps S23 or S24 '.

In step S26 ', if the PRACH the number of transmissions on this upstream components carrier wave exceedes predetermined threshold, and the PRACH on this upstream components carrier wave transmits when timing does not exceed predetermined the time limit, then determine the PRACH bust this on this upstream components carrier wave, and from the upstream components carrier wave of the multiple PRACH of being configured with resources of the remaining PRACH of not having bust this, select a upstream components carrier wave to carry out PRACH transmission, and return above-mentioned steps S23 or S24 ' until determine in all PRACH transmission be configured with on the upstream components carrier wave of PRACH resource all failed.

In order to avoid the failure of uplink communication as much as possible, in one embodiment, when after the PRACH bust this that subscriber equipment 1 is determined on this upstream components carrier wave in above-mentioned steps S26 or step S26 ', this subscriber equipment 1 can send second notification message to base station 2 by RRC or MAC control element, and this second notification message is for the PRACH bust this of signals base 2 subscriber equipmenies 1 on this upstream components carrier wave.

The method of the detection PRACH bust this related in such scheme one and scheme two can be used for such as, following application scenarios: the switching, the arrival of uplink/downlink data, SR (SchedulingRequest, dispatch request) bust this etc. of minizone.

Scheme three: be only configured with PRACH resource on a upstream components carrier wave, and PRACH re-transmission only can be carried out on this upstream components carrier wave.

Fig. 3 show according to an embodiment of the invention in the subscriber equipment of the wireless communication system based on carrier aggregation technology for detecting the method flow diagram of PRACH bust this.

With reference to Fig. 3, first in step S31, subscriber equipment 1 receives the configuration information from base station 2.

In the present embodiment, according to this configuration information, subscriber equipment 1 knows that base station 2 is only configured with PRACH resource on a upstream components carrier wave, and PRACH re-transmission only can be carried out on this upstream components carrier wave.

So in step s 32, subscriber equipment 1 carries out PRACH transmission on the upstream components carrier wave that this is configured with PRACH resource.

If this time PRACH bust this on this upstream components carrier wave, so, in step S33, subscriber equipment 1 adds 1 to the PRACH the number of transmissions on this upstream components carrier wave, and judges whether this PRACH the number of transmissions exceedes predetermined threshold.

If the PRACH the number of transmissions on this upstream components carrier wave does not exceed predetermined threshold, so, enter step S34, subscriber equipment 1 continues to carry out PRACH re-transmission on this upstream components carrier wave, and returns above-mentioned steps S33.

If the PRACH the number of transmissions on this upstream components carrier wave exceedes predetermined threshold, so, enter step S35, subscriber equipment 1 is determined in all PRACH bust thiss be configured with on the upstream components carrier wave of PRACH resource.

It should be noted that, in scheme three, owing to being only configured with PRACH resource on a upstream components carrier wave, therefore, the PRACH bust this be configured with on the upstream components carrier wave of PRACH resource at this is just equivalent in the spendable all PRACH bust thiss be configured with on the upstream components carrier wave of PRACH resource of subscriber equipment 1.

If all failed in all PRACH transmission be configured with on the upstream components carrier wave of PRACH resource, so, enter step S36, subscriber equipment 1 is from MAC (MediaAccessControl, medium education) layer sends the first notification message to RRC (RadioResourceControl, wireless heterogeneous networks) layer.

The method of the detection PRACH bust this related in such scheme three can be used for such as, initially accessing application scenarios.

Same, SR (SchedulingRequest) bust this process is also the problem needing in 3GPP to solve.In LTE, a upstream components carrier wave is only configured with for uplink communication for a subscriber equipment, when SR (SchedulingRequest) bust this on this upstream components carrier wave, also when namely SR number of retransmissions exceedes the maximum retransmission preset, subscriber equipment is by the up configuration information on this upstream components carrier wave of release, as PUCCH/SRS, the UL/DLgrant etc. of configuration.And in LTE-A, because a user device configuration has multiple upstream components carrier wave.Therefore, when after SR bust this, subscriber equipment 1 can have following 3 kinds of processing methods:

Method one: subscriber equipment 1 does not discharge the up configuration information on any upstream components carrier wave, and from the multiple upstream components carrier waves being configured with PRACH resource, select a upstream components carrier wave to carry out PRACH transmission.

For subscriber equipment 1, PRACH resource can only be configured on a upstream components carrier wave, also can be configured on multiple upstream components carrier wave.

When PRACH resource is only configured on a upstream components carrier wave, so, when after SR bust this, subscriber equipment 1 carries out PRACH transmission on this upstream components carrier wave.

When PRACH resource distribution is on multiple upstream components carrier wave, so, when after SR bust this, in one embodiment, subscriber equipment 1 can select a upstream components carrier wave to carry out PRACH transmission randomly in the upstream components carrier wave of the multiple PRACH of being configured with resource.

In another embodiment, subscriber equipment 1 can select PRACH transmission time slot upstream components carrier wave the earliest to carry out PRACH transmission in the upstream components carrier wave of the multiple PRACH of being configured with resource.

Preferably, in the above-described embodiments, should be different from for the upstream components carrier wave carrying out PRACH transmission the upstream components carrier wave that is configured with SR resource selected by subscriber equipment 1.
