As shown in Figure 2, the present embodiment provides a kind of method detecting ascending control information, comprises following content.
201, PUSCH is detected in base station.
202, if this base station detects the indication information that UE sends on PUSCH, this indication information represents in the UCI sent on this PUSCH and contains cycle CSI, then the cycle CSI comprised in above-mentioned UCI is detected in this base station on this PUSCH.
As an embodiment, if downlink data dispatching is not carried out to above-mentioned UE in above-mentioned base station, then the indication information that this base station detects comprises virtual nack message.
As another embodiment, above-mentioned indication information comprises the first indication information or the second indication information, above-mentioned first indication information represents in the UCI sent on above-mentioned PUSCH and comprises cycle CSI, do not comprise the response message of UE to downlink data, above-mentioned second indication information represents in the UCI sent on this PUSCH and comprises the response message of cycle CSI and UE to downlink data.If the indication information that above-mentioned base station detects on above-mentioned PUSCH is above-mentioned first indication information, then above-mentioned 202 also comprise: the upstream data of carrying on above-mentioned PUSCH is detected in above-mentioned base station; If the indication information that above-mentioned base station detects on above-mentioned PUSCH is above-mentioned second indication information, then above-mentioned 202 also comprise: the above-mentioned UE of carrying on above-mentioned PUSCH is detected to the response message of downlink data in above-mentioned base station.
As another embodiment, if this base station does not detect above-mentioned indication information on above-mentioned PUSCH, then upstream data is detected in this base station on the PUSCH of priority lower than above-mentioned PUSCH; Priority in the present embodiment comprises the priority of the PUSCH carrying UCI of base station configuration, or the PUSCH preset between base station and subscriber equipment carries the priority of UCI.
In the present embodiment, base station, by identifying that the indication information of UE transmission is known, which PUSCH carries UCI, when especially not comprising UE when only comprising cycle CSI in UCI to the confirmation of downlink data response, the PUSCH carrying UCI also can correctly be identified in base station, and then can carry out the detection of upstream data exactly.
In the specific embodiment of as shown in Figure 3, base station is for evolution base station eNB, UE in the present embodiment has been configured 3 up-link carriers CC1, CC2 and CC3, and the priority that corresponding respectively PUSCH1, PUSCH2 and the PUSCH3 of these 3 up-link carriers carries UCI is: PUSCH1 > PUSCH2 > PUSCH3.In the present embodiment, eNB does not carry out downlink data dispatching to UE, eNB 3 uplink scheduling authorizations UL_grant1, UL_grant2 and UL_grant3 dispatch 3 up-link carriers CC1, CC2 and CC3 of this UE respectively, but UE only have received UL_grant2 and UL_grant3, undetected UL_grant1, therefore UE thinks that ascending resource PUSCH1 is not scheduled.Because eNB does not carry out downlink data dispatching to UE, so UE does not confirm that the uplink ACK/nack message of downlink data sends.Therefore, when UE will send UCI, UE only sends cycle CSI, and does not send uplink ACK/nack message.Under above-mentioned scene, the present embodiment specifically comprises following content.
301, UE selects on PUSCH2, send upstream data, cycle CSI and virtual nack message.UE only sends upstream data on PUSCH3.Because UE thinks that ascending resource PUSCH1 is not scheduled, therefore do not send PUSCH1.In the present embodiment, UE does not confirm that the uplink ACK/nack message of downlink data sends, and virtual nack message sends as indication information by UE, represents in the UCI sent on this PUSCH and comprises cycle CSI.
302, eNB detects PUSCH1, PUSCH2 and PUSCH3 respectively.
303, eNB detects virtual nack message on PUSCH2, knows in the UCI that UE sends on this PUSCH2 and comprises cycle CSI, namely UE multiplexing for cycle CSI on PUSCH2, therefore eNB sense cycle CSI and upstream data on PUSCH2.Because eNB does not detect virtual nack message at PUSCH3, know UE not multiplexing for cycle CSI on PUSCH3, therefore eNB only detects upstream data on PUSCH3.Because the priority of the carrying UCI of PUSCH1 is the highest, if when UE does not have undetected UL_grant1, eNB should detect UCI at PUSCH1, but eNB does not detect UCI at PUSCH1, but on PUSCH2, cycle CSI detected, therefore eNB judges the UL_grant1 that the undetected PUSCH1 of UE is corresponding, and then eNB can not detect upstream data on PUSCH1.
In the present embodiment, virtual nack message is sent while UE sends cycle CSI on PUSCH, making eNB can by the existence of virtual nack message being detected, judging to comprise cycle CSI in the UCI that this PUSCH sends, avoid UE and abandon cycle CSI and the loss of downlink throughput capacity that brings.Simultaneously, base station, by identifying that the indication information of UE transmission is known, which PUSCH carries UCI, when especially not comprising UE when only comprising cycle CSI in UCI to the confirmation of downlink data response, the PUSCH carrying UCI also can correctly be identified in base station, and then can carry out the detection of upstream data exactly.
In the specific embodiment of as shown in Figure 4, base station is for evolution base station eNB, and eNB carries out downlink data dispatching to UE descending scheduling mandate DL_grant, and UE needs downlink data feeding back uplink ACK/NACK information.But as the undetected above-mentioned DL_grant of UE, UE just thinks does not have downlink data to send, so just only have cycle CSI in the UCI of this UE transmission, not for the uplink ACK/nack message of downlink data feedback, that is: UE only sends cycle CSI, and does not have uplink ACK/nack message to send.Under above-mentioned scene, the present embodiment specifically comprises following content.
401, UE selects a PUSCH to send cycle CSI and virtual nack message.Above-mentioned virtual nack message is virtual negative response information, represents in the UCI sent on this PUSCH and comprises cycle CSI.The bit number of above-mentioned virtual nack message is determined to the downlink member carrier set of this UE according to configuration.
The bit number of above-mentioned virtual nack message is the same with the bit number of uplink ACK/nack message that UE feeds back for downlink data, is all to determine to the downlink member carrier set of this UE according to configuration.Such as: eNB configures and comprises 3 member carrier { CC1 to the descending carrier set of UE, CC2, CC3}, and the uplink ACK of corresponding 1 bit of the downlink data transmission of each carrier wave/nack message feedback, the bit number of uplink ACK/nack message that then UE now feeds back is 3, and the bit number of the virtual nack message of feedback is also 3.Further, the bit number of uplink ACK/nack message that UE feeds back for downlink data and the bit number of virtual nack message and eNB actual schedule have nothing to do to the carrier number of UE, and also the actual carrier number be scheduled detected has nothing to do with UE.Such as, eNB only scheduled CC2 and CC3 of above-mentioned UE sometime, so the bit number of this UE feeding back uplink ACK/NACK information is still defined as 3 according to the size (the member carrier number namely in set) of downlink member carrier set, and when feeding back virtual nack message, the bit number of this virtual nack message is also 3; Again such as, eNB scheduled the CC1 of above-mentioned UE sometime, CC2 and CC3, but this UE the is undetected DL_grant1 of CC1, namely this UE thinks that eNB only scheduled CC2 and CC3, so the bit number of this UE feeding back uplink ACK/NACK information is still defined as 3 according to the size (the member carrier number namely in set) of downlink member carrier set, and when feeding back virtual nack message, the bit number of this virtual nack message is also 3.
402, eNB detects above-mentioned PUSCH, if above-mentioned virtual nack message detected, is informed in the UCI that this PUSCH sends and comprises cycle CSI, then eNB sense cycle CSI and upstream data on this PUSCH.In specific implementation process, when eNB detects uplink ACK/nack message that UE feeds back for downlink data on above-mentioned PUSCH, because UE does not have feeding back uplink ACK/NACK information, so eNB detects is virtual nack message.Because above-mentioned virtual nack message is 3 bits, identical with the uplink ACK/nack message length of UE Normal Feedback, therefore eNB is when the virtual nack message of 3 bits being detected, the up nack message that UE sends for downlink data can be thought, namely UE is thought not receive downlink data and the negative response information sent, and then eNB can re-start the scheduling of downlink data, the loss of downlink data report can not be caused.
The indication information that in the present embodiment, UE sends is for virtual nack message, eNB not only can be made to pass through to detect that virtual nack message knows carrying cycle CSI on PUSCH, and, because the bit number of virtual nack message is identical with the uplink ACK/nack message length of UE Normal Feedback, therefore eNB can when detecting virtual nack message, according to the situation receiving the up nack message that UE feeds back for downlink data, re-start the scheduling of downlink data, avoid the loss of downlink data.
