Description
Technical field
The present invention relates to wireless communication field, particularly relate to a kind of method and subscriber equipment of selecting Physical Uplink Shared Channel.
Background technology
At third generation partner program long evolving system (The 3rd Generation Partnership Project Long Term Evolution, be called for short 3GPP LTE) in, subscriber equipment (User Equipment, be called for short UE) to base station (eNodeB, abbreviation eNB) ascending control information (the Uplink Control Information that sends, be called for short UCI) comprising: to Physical Downlink Shared Channel (Physical Downlink Shared Channel, abbreviation PDSCH) correct/error response message (Acknowledgement/Negative Acknowledgement, be called for short ACK/NACK), the channel condition information of down channel (Channel State Infprmation is called for short CSI) etc.
Wherein, UE then, reports to the base station with the CSI that obtains according to the channel condition information CSI of downlink reference signal (reference signal) acquisition down channel.Data modulation coding mode and the physical resource position of UE determined to send to according to the CSI of UE feedback in the base station, and transmission mode.In the LTE system, CSI comprises three kinds of forms: channel quality indication (Channels Quality Indication, abbreviation CQI), pre-coding matrix indication (Pre-coding Matrix Indicator is called for short PMI), order indication (Rank Indicator is called for short RI).
In the LTE system, the ACK/NACK response message can be gone control channel (Physical Uplink Control physically, be called for short PUCCH) go up transmission, the shared channel (Physical Uplink Shared Channel is called for short PUSCH) of also can going is physically gone up transmission.On certain subframe (subframe), if UE does not send PUSCH, the ACK/NACK response message is transmitted on PUCCH; If UE sends PUSCH, the ACK/NACK response message is carried on PUSCH and goes up transmission.
In the LTE system, UE has periodic feedback and aperiodic to feed back dual mode to the CSI report of down channel, is called cycle channel status information reports (periodic CSI reporting) and aperiodic channel status information reports (aperiodic CSI reporting).Wherein, for the CSI of periodic feedback, on certain subframe, if UE does not send PUSCH, CSI transmits on PUCCH; If UE sends PUSCH, CSI is carried on PUSCH and goes up transmission.For the CSI of feedback aperiodic, only on PUSCH, transmit.
In the LTE system, the base station is by the PUSCH transmission of uplink scheduling authorization (Uplinkgrant is called for short UL grant) certain UE of signaling scheduling.The uplink scheduling authorization signaling can be by having Downlink Control Information (Downlink Control Information, abbreviation DCI) Physical Downlink Control Channel of form 0 (format 0) (Physical Downlink Control Channel is called for short PDCCH) sends to the UE that is dispatched.There is 1 bit to be used to trigger UE among the DCI format 0 and carries out CSI report aperiodic, be called channel quality indication request (CQI request).
If UE detects the PDCCH with DCI format 0 form that belongs to it, then send PUSCH according to the UL grant that wherein comprises.If the 1 bit CQIrequest that UE detects among the DCI format 0 is changed to ' 1 ', then in the PUSCH that this DCI format 0 is dispatched, send the CSI of feedback aperiodic.
In the LTE system, also defined a kind of special DCI format 0, be specifically designed to and trigger CSI report aperiodic, and transmission bearer Uplink Shared Channel (Uplink Shared Channel not among the PUSCH that is dispatched, abbreviation UL-SCH) transmission block (Transport Block is called for short TB).
It is pointed out that general PUSCH is by corresponding UL grant dynamic dispatching (Dynamically Scheduled).But some special P USCH, such as, non-self-adapting retransmits the PUSCH of (non-adaptive retransmission), semi-continuous scheduling (Semi-Persistently Scheduled, abbreviation SPS) PUSCH, UL grant does not dispatch one to one, but send according to before certain UL grant, such as, the PUSCH that non-self-adapting retransmits sends according to the UL grant that transmits (initial transmission) first, and the PUSCH of semi-continuous scheduling sends according to the UL grant that activates semi-continuous scheduling (Semi-Persistent Scheduling Activation).Because UL grant does not dispatch one to one, also just can't trigger new CSI report aperiodic by CQI request signaling.In the LTE system, cyclic redundancy check (CRC) (the Cyclic Redundancy Check of the payload of the PDCCH of dynamic dispatching PUSCH (PDCCH payload), abbreviation CRC) bit is by Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Cell-Radio Network Temporary Identifier, be called for short C-RNTI) scrambling, and the CRC bit of the payload of the PDCCH of the PUSCH of activation semi-continuous scheduling is by semi-continuous scheduling Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Semi-Persistent Scheduling Cell-Radio Network Temporary Identifier is called for short SPS C-RNTI) scrambling.
In addition, the uplink scheduling authorization signaling UL grant that a class is special is called accidental access response mandate (Random Access Response Grant is called for short RAR grant) signaling bear and sends to the UE that corresponding initiation inserts at random in PDSCH.In based on non-competing random access procedure (non-contention based random access procedure), also include 1bit CQI request among the RAR grant, be used to trigger CSI report aperiodic.If the UE that initiates to insert at random detects the RAR grant that belongs to it, then send PUSCH in view of the above, this PUSCH is called dispatching uplink transmission first, and (First scheduled UL transmission is called Message 3 again, Msg.3) in random access procedure.If the 1 bit CQI request that UE detects among the RAR grant is changed to ' 1 ', then in Msg.3, send the CSI of feedback aperiodic.In the random access procedure (contention based random access procedure) based on competition, the 1bit CQI request among the RAR grant keeps, and is not used in to trigger CSI report aperiodic.
Senior Long Term Evolution (LTE-Advanced is called for short LTE-A) system is the evolution system of future generation of LTE system, adopts carrier aggregation (Carrier Aggregation is called for short CA) technological expansion transmission bandwidth, supports bigger hardware circuit solution.Fig. 1 is the LTE-A system carrier aggregation schematic diagram according to correlation technique.As shown in Figure 1, the carrier wave of each polymerization is called one " component carrier " (Component Carrier is called for short CC).A plurality of component carriers can be positioned at same frequency range (frequency band), also can be positioned at different frequency range.
In the LTE-A system, the base station can send a plurality of PDSCH respectively to same subscriber equipment on a plurality of component carriers.According to prior art, to the ACK/NACK response message of PDSCH, the CSI of periodic feedback can send by PUCCH on the component carrier of a subscriber equipment specific (UE specific).The specific component carrier of described subscriber equipment is semi-static configuration, is called the principal component carrier wave (Primary Component Carrier is called for short PCC) or the main plot (Primary cell is called for short Pcell) of this subscriber equipment again.And configuration give all the other component carriers of this subscriber equipment be called this subscriber equipment from component carrier (Secondary Component Carrier is called for short SCC) or from the sub-district (Secondary cell is called for short Scell).It has been generally acknowledged that the channel quality of PCC is better.Subscriber equipment can only send PUCCH and SPS PUSCH on its principal component carrier wave, and can not send PUCCH or SPS PUSCH from component carrier SCC at it.
In the LTE-A system, subscriber equipment can send a plurality of PUSCH respectively simultaneously on a plurality of component carriers.According to prior art, UCI (comprising the ACK/NACK response message at least, the CSI that cycle and aperiodic feed back) can transmit on any one PUSCH.But on the subframe, UCI is carried at most on the PUSCH.Therefore, on certain subframe, if subscriber equipment sends a plurality of PUSCH, and have UCI need be carried on when PUSCH is last to be transmitted, subscriber equipment need select a PUSCH to be used to carry UCI in a plurality of PUSCH.
It is pointed out that UCI transmits at PUCCH or on PUSCH, or part UCI transmits on PUCCH, part is transmitted on PUSCH, is to determine according to concrete scene.Such as, aperiodic, the CSI of feedback can only transmit on PUSCH; The CSI of periodic feedback and ACK/NACK response message are transmitted on PUCCH when not having PUSCH to send, and when PUSCH sends, according to system configuration, are transmitting on the PUCCH and/or are transmitting on PUSCH.What the present invention paid close attention to is, has UCI (comprise need on this subframe feed back all or part of UCI) need be carried on the scene that PUSCH goes up transmission.
When the method for the PUSCH of design alternative carrying UCI, need to consider following factor:
Consider the reception complexity, the base station needs clear and definite subscriber equipment to carry UCI on which PUSCH, therefore, when selecting PUSCH, should make the base station with subscriber equipment carrying UCI on which PUSCH be had consistent understanding, avoids occurring deviation and fuzzy.
Because the importance of UCI when selecting PUSCH, needs to guarantee the transmission performance of UCI.
Because UCI is carried on the PUSCH and can the upstream data that be sent by PUSCH be originally impacted, and when selecting PUSCH, should reduce the influence to data as far as possible under the prerequisite of guaranteed performance.
Such as, if estimating subscriber equipment, the base station can on the PUSCH of certain dynamic dispatching, carry UCI, then the base station can dispose and adjust when this PUSCH of scheduling accordingly, thereby guarantees the transmission performance of UCI, reduces the influence to upstream data simultaneously.
To sum up, how subscriber equipment selects a PUSCH to be used to carry UCI in a plurality of PUSCH, becomes a problem demanding prompt solution.

Embodiment
Select the subscriber equipment of Physical Uplink Shared Channel to comprise Physical Uplink Shared Channel selection module.
Physical Uplink Shared Channel is selected module to be used for a plurality of Physical Uplink Shared Channels that the priority according to Physical Uplink Shared Channel sends on a subframe to select the highest Physical Uplink Shared Channel of priority to be used to carry ascending control information.
The priority of Physical Uplink Shared Channel is by the one or more decisions in the following factor: the priority of Physical Uplink Shared Channel place component carrier, whether be the Physical Uplink Shared Channel of dynamic dispatching, whether be to have triggered the Physical Uplink Shared Channel that the uplink scheduling authorization signaling of aperiodic channel status information (CSI) report is dispatched.
The Physical Uplink Shared Channel that the described uplink scheduling authorization signaling that has triggered aperiodic channel status information (CSI) report is dispatched also can be described as carrying the Physical Uplink Shared Channel of aperiodic state information.
As shown in Figure 2, when certain subscriber equipment sends a plurality of PUSCH on a subframe, and when having UCI need be carried on PUSCH to go up transmission, select the method for Physical Uplink Shared Channel to comprise: to select the highest Physical Uplink Shared Channel of priority to be used to carry ascending control information in a plurality of Physical Uplink Shared Channels that subscriber equipment sends on a subframe according to the priority of Physical Uplink Shared Channel.
The priority of Physical Uplink Shared Channel is by the one or more decisions in the following factor: the priority of Physical Uplink Shared Channel place component carrier, whether be the Physical Uplink Shared Channel of dynamic dispatching, whether be to have triggered the Physical Uplink Shared Channel that the uplink scheduling authorization signaling of aperiodic channel status information (CSI) report is dispatched.
Wherein, the priority of component carrier is disposed by high-level signaling.Perhaps, the priority of component carrier is by component carrier call number (Component Carrier index the is called for short CC index) indication of component carrier.Preferably, the component carrier call number is more little, and priority is high more.Perhaps, the priority of principal component carrier wave (PCC) is the highest, and promptly the priority of principal component carrier wave (PCC) is higher than from the priority of component carrier (SCC).Indicate by component carrier call number from the priority of component carrier SCC from component carrier.Preferably, the component carrier call number is more little, and priority is high more.
Can determine the priority of different PUSCH in this method according to above-mentioned factor:
For example, the priority of the Physical Uplink Shared Channel of dynamic dispatching is higher than the priority of the Physical Uplink Shared Channel of non-dynamic dispatching.
The PUSCH of described dynamic dispatching is meant the PUSCH of corresponding uplink scheduling authorization signaling scheduling, the PUSCH that corresponding PDCCH scheduling is promptly arranged, the PUSCH of described non-dynamic dispatching is meant the PUSCH that does not have corresponding uplink scheduling authorization signaling scheduling, does not promptly have the PUSCH of corresponding PDCCH scheduling.Preferably, the PUSCH of described dynamic dispatching comprises the pairing PUSCH of PDCCH (being the first PUSCH in the PUSCH transmission of semi-continuous scheduling) of the PUSCH that activates semi-continuous scheduling and the PUSCH that the self adaptation in the semi-continuous scheduling retransmits.
Perhaps, the PUSCH of described dynamic dispatching is meant that the CRC check bit of payload of the PDCCH that is used to dispatch described PUSCH is by the C-RNTI scrambling.Preferably, the PUSCH of described dynamic dispatching does not comprise the PUSCH of semi-continuous scheduling and the PUSCH that non-self-adapting retransmits.
For example, the priority that has triggered the Physical Uplink Shared Channel that the uplink scheduling authorization signaling of aperiodic channel status information reports dispatched is higher than the priority of other Physical Uplink Shared Channel that does not satisfy this condition.
For example, triggered aperiodic channel status information reports but the Physical Uplink Shared Channel dispatched not the priority of the Physical Uplink Shared Channel dispatched of the uplink scheduling authorization signaling of the transmission block of transmission bearer Uplink Shared Channel (UL-SCH) be higher than the priority of the Physical Uplink Shared Channel that the uplink scheduling authorization signaling of the transmission block of the Physical Uplink Shared Channel transmission bearer Uplink Shared Channel that has triggered aperiodic channel status information reports but dispatched dispatched.Wherein, to subscriber equipment, on the subframe, there is uplink scheduling authorization signaling to trigger CSI report aperiodic at most and the PUSCH that the dispatched transmission block of transmission bearer UL-SCH not.
For example, triggered CSI report aperiodic but the PUSCH that dispatched or not the priority of the PUSCH that of the uplink scheduling authorization signaling of the transmission block of transmission bearer UL-SCH is the not highest.
For example, the priority of the Physical Uplink Shared Channel that transmits first is higher than the priority of the Physical Uplink Shared Channel of re-transmission.
For example, the priority of the PUSCH of self adaptation re-transmission is higher than the PUSCH that non-self-adapting retransmits.
For example, the PUSCH based on the scheduling of the accidental access response in the random access procedure of competition is not used in carrying UCI.
For the clear priority of how determining different Physical Uplink Shared Channels of describing according to above-mentioned factor, in this method, Physical Uplink Shared Channel is divided into a plurality of grades (level) according to above-mentioned factor, the Physical Uplink Shared Channel priority that grade is high more is high more.When the grade of a plurality of Physical Uplink Shared Channels is identical, determine the priority of these a plurality of Physical Uplink Shared Channels according to predefined rule.
Preferably, when the priority level of a plurality of Physical Uplink Shared Channels is identical, select a highest Physical Uplink Shared Channel of priority of this a plurality of Physical Uplink Shared Channels place component carrier.
It should be noted that; the introducing of grade conception is in order to know how description determines the priority of Physical Uplink Shared Channel; anyly determine the method for the priority of Physical Uplink Shared Channel according to above-mentioned factor, though whether service rating or similar notion, the scope that all belongs to the present invention and protected.
