Description

Determine the method and user equipment of control channel resource
Technical field
The present invention relates to the communications field, determines that the method for control channel resource and user set more particularly in the communications field It is standby.
Background technology
Long Term Evolution (Long Term Evolution, referred to as " LTE ") the 8/9/10th version (Release 8/9/10, Referred to as " Rel-8/9/10 ") communication system employs the technology of dynamic dispatching, to improve the performance of communication system, i.e. base station (Evolved NodeB, referred to as " eNB ") is according to the channel of each user equipment (User Equipment, being referred to as " UE ") Situation is scheduled and distributed resource so that each scheduled user equipment is transmitted on its optimal channel. In downlink transfer, eNB sends Physical Downlink Shared Channel according to the result of dynamic dispatching for each scheduled user equipment (Physical Downlink Shared Channel, referred to as " PDSCH ") and corresponding Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as " PDCCH "), wherein PDSCH carry eNB be sent to by The data of the user equipment of scheduling, PDCCH are mainly used to indicate corresponding PDSCH transformat, i.e. schedule information, including money The distribution in source, the size of transmission block, modulation coding mode, transmission rank and precoding matrix information etc..
PDCCH and PDSCH time division multiplexings in a subframe, therefore PDCCH number can be supported of a subframe be by Limit, i.e. the number of base station scheduling user equipment is limited.PDCCH capacity limitation problem is in LTE Rel-10 communication systems Further evolution in it is more prominent.Especially, the commonly used multiple-input and multiple-output of evolution system (Multiple Input Multiple Output, referred to as " MIMO ") technology, to improve the spectrum efficiency of communication system, this means that base station while adjusted The quantity of the user equipment of degree adds, it is therefore desirable to more PDCCH.In addition, one considered in evolution system is critically important Scene be exactly heterogeneous network, a specific implementation of the scene is grand except setting in the coverage of a macrocell Outside base station, be also provided with multiple remote radio unit (RRU)s (Remote Radio Unit, referred to as " RRU "), these RRU and its The macrocell at place has identical cell ID, and PDCCH is used and is based on demodulated reference signal (Demodulation Transmission means Reference Signal, referred to as " DMRS "), therefore each RRU can individually service some users and set It is standby.But each RRU is use that is transparent, thus substantially increasing base station scheduling in this scenario for user equipment The quantity of family equipment, the capacity of the PDCCH required for thus also increasing.
Therefore, communication system is strengthened existing PDCCH, i.e., mark off a part in original PDSCH region Resource, for transmitting the PDCCH of enhancing, that is, strengthen Physical Downlink Control Channel (Enhanced Physical Downlink Control Channel, referred to as " E-PDCCH ").The resource for so distributing to control channel just has very big flexibility ratio, PDCCH capacity is increased, while E-PDCCH can also use the transmission means based on DMRS, it is possible to achieve spatially Reuse to improve the efficiency of transmission of control channel.For example, the control channel for the user equipment served under different RRU is complete Same running time-frequency resource can be taken, as long as spatially being isolated.
In LTE Rel-8/9/10 communication systems, generally use hybrid automatic repeat-request (Hybrid Automatic Repeat Request, referred to as " HARQ ") technology improves the performance of communication system, and also may proceed to should for the HARQ technologies In the communication system of evolution, such as applied to LTE Rel-11.Because the scheduled user equipment of dynamic is needed on eNB Row feedback acknowledgment (Acknowledgement, referred to as " ACK ")/deny (Non-Acknowledgement, referred to as " NACK ") information, therefore the user equipment that dynamic is scheduled is it needs to be determined that the resource of uplink feedback ACK/NACK information.Consider The randomness of dynamic dispatching and the utilization ratio of resource, the resource of uplink feedback ACK/NACK information need to reserve using dynamic Method, i.e., when PDSCH is scheduled, can just reserve resource, and be unsuitable for using semi-static reserved method.Therefore, for Using for the communication system of HARQ technologies, it is necessary to solve technical problem exactly when user equipment detect E-PDCCH and After PDSCH, the resource for uplink feedback ACK/NACK information how is dynamically determined.
In the related art, in the case of PDCCH and PDSCH are multiplexed together, i.e., PDCCH is not being strengthened In the case of, the feedback of ACK/NACK information is physically row control channel (Physical Uplink Control Carried out on Channel, referred to as " PUCCH ") in a manner of code division multiplexing, i.e., each user equipment passes through a time-frequency two-dimensional The sequence pair ACK/NACK information of spread spectrum is sent after being modulated, wherein for the user equipment that each dynamic is scheduled, Resource for uplink feedback ACK/NACK information is control channel unit (the Control Channel by PDCCH Element, referred to as " CCE ") sequence number implicitly determine.
However, in the case of PDCCH, E-PDCCH and PDSCH are multiplexed together, lead to if still used in correlation technique CCE sequence number is crossed to determine the method for the resource for uplink feedback ACK/NACK information, then due to being based under different RRU The E-PDCCH of DMRS transmission can take identical running time-frequency resource and different DMRS ports, and different E-PDCCH is possible to have There are identical control channel logical labels or sequence number, thus feeding back ACK/nack message between different user devices may be caused The problem of resource conflicts, i.e. two or more user equipment take same resource, so as to different user ACK/NACK information between equipment interferes.
The content of the invention
Therefore, the embodiments of the invention provide a kind of method and user equipment for determining control channel resource, being capable of dynamic Ground determines the resource for uplink feedback ACK/NACK information, and the resource contention between different user devices can be avoided to ask Topic.

User equipment is according to the successful E-PDCCH of detection, it may be determined that forms first virtual resource blocks of the E-PDCCH Sequence number nVRB, i.e., the virtual resource blocks where first control channel logic unit, wherein nVRB=0,1 ..., NVRB- 1, NVRB It is the number of the virtual resource blocks of configuration, and the physical resource mapped with first virtual resource blocks is corresponding first day The sequence number n of line end mouthDMRS, wherein nDMRS=0,1 ..., NDMRS- 1, NDMRSIt is the number of first antenna port, such as DMRS antennas The sequence number n of port 7 and 8DMRSRespectively 0 and 1.For example, in the embodiment shown in fig. 5, first virtual money of user equipment 1 The sequence number n of source blockVRBFor 8, the sequence number n of first virtual resource blocks of user equipment 2VRBFor 4, first void of user equipment 3 Intend the sequence number n of resource blockVRBFor 0, the sequence number n of first virtual resource blocks of user equipment 4VRBFor 7, the virtual resource blocks of configuration Number NVRBFor 16, the sequence number n of first antenna portDMRSFor 0, the number N of first antenna portDMRSFor 1.Alternatively, first The sequence number of individual virtual resource blocks can also use the sequence number of corresponding Physical Resource Block.For example, first of user equipment 3 The serial number 6 of Physical Resource Block corresponding to virtual resource blocks, then the sequence number of first virtual resource blocks can be 6.
In S230, user equipment determines the first control channel resource for feeding back the ACK/NACK information.Alternatively, User equipment can be according to the serial number information of acquisition, antenna port information, the transmission mode of offset and data channel, it is determined that should First control channel resource.Alternatively, serial number information, the antenna port information that user equipment can be according to acquisition, offset and The form of the control channel of the detection, determine the first control channel resource.
For example, the Physical Resource Block being allocated in the EPDCCH set of user equipment 1 is 4 to number, wherein each physics ECCE number of resource block pair is 4, and the DMRS port number of each Physical Resource Block centering is also 4, respectively DMRS port 107,108,109,110, a DMRS port is respectively associated in each ECCE, for example, 4 of a Physical Resource Block centering ECCE, 0,1,2,3 is respectively associated DMRS port 107,108,109,110；4 EPDCCH things in the EPDCCH set configured It is respectively 0,1,2 to 16 corresponding ECCE to manage resource block ... 15；Next is allocated to user equipment 1 for above-mentioned configuration The offset of uplink ACK/NACK resources of EPDCCH set is
User equipment 1 obtains first ECCE for detecting successful EPDCCH in blind detection process is carried out to EPDCCH Marked as nECCE, EPDCCH is in its nECCEDMRS port used and the EPDCCH detected in the Physical Resource Block at place Form, ACK/NACK resources are then determined according to following method.
When the EPDCCH that success detects is the first form, such as DCI format1A, determine that first control channel provides The sequence number in sourceIt is as follows：
Wherein
When the EPDCCH that success detects is the second form, such as DCI format1/1B/1D/2/2A/2B/2C/2D, really The sequence number of the fixed first control channel resourceIt is as follows：
Wherein offset is dynamically indicated by EPDCCH, and has at least one bit having to explicitly to indicate in EPDCCH DCI Offset value.Under PDSCH each transmission mode, there is two kinds of EPDCCH form, one of which is DCI format 1A, this is mainly used when PDSCH is retracted or some are reconfigured, and at this moment the condition of transmission channel may be weaker. In order to ensure DCI format 1A performance, ACK/NACK resources directly can be determined using the information of antenna port, without Need to increase several bits in DCI format 1A to solve the problems, such as ACK/NACK resource contentions, because can so increase DCI format 1A load, causes the decline of performance；And under another form, due to being PDSCH normal transmission, It can increase by 1 or multiple bit wherein and having to explicitly indicate an offset, so as to neatly avoid between different user The conflict of ACK/NACK resources.
Alternatively, user equipment 1 determines the transmission mode of the PDSCH scheduled in EPDCCH, and blind to EPDCCH progress In detection process, obtain first ECCE detecting successful EPDCCH marked as nECCE, EPDCCH is in its nECCEThe thing at place DMRS port used in resource block is managed, ACK/NACK resources are then determined according to following method.
When the PDSCH by scheduled in EPDCCH is the first transmission mode, such as TM10, determine the first control letter The sequence number of road resourceIt is as follows：
Wherein offset is dynamically indicated by EPDCCH, and has at least one bit having to explicitly to indicate in EPDCCH DCI Offset value.
When the PDSCH by scheduled in EPDCCH is the second transmission mode, such as TM1-9, determine first control The sequence number of channel resourceIt is as follows：
Wherein
When PDSCH transmission mode is TM10, that is, when carrying out CoMP operation, the number of users at this moment dispatched may add A lot, such as in CoMP scenes 4, reserved many ACK/NACK resources are thus needed.In order to save ACK/NACK resources, It is overlapping or partly overlap that the corresponding ACK/NACK resources of two EPDCCH set can be configured, so can reuse some not Same ACK/NACK resources.For example, if ACK/NACK resources are only determined according to the first of EPDCCH ECCE, then when When EPDCCH aggregation level is 2 or is bigger, the ACK/NACK resources corresponding to several ECCE after first ECCE are just It is empty, is not used.Therefore, it can increase by 1 or multiple bit in EPDCCH to indicate the skew of ACK/NACK resources Amount, so as to the above-mentioned utilization of resources not used, improve the utilization rate of resource.But when PDSCH transmission mould When formula is other, because the number of users of scheduling will not be a lot, directly ACK/NACK resource cans are determined using antenna port.
Here only it is one embodiment, the invention is not restricted to this.
It should be understood that after user equipment determines the first control channel resource for feeding back ACK/nack message, due to Uplink feedback ACK/NACK information is therefore the first control channel that actually each user equipment determines based on code division multiplexing Resource is the frequency expansion sequence in a resource block.User equipment is modulated by using ACK/NACK information to the frequency expansion sequence Afterwards, sent on an antenna, so as to realize uplink feedback ACK/NACK information, as shown in Fig. 6 (A).
When user equipment sends diversity scheme (Spatial Orthogonal Resource using orthogonal space resource Transmit Diversity, referred to as " SORTD ") when sending the ACK/NACK information, determination according to embodiments of the present invention The method 200 of control channel resource also includes：
S240, user equipment determine the second control channel resource for feeding back the ACK/NACK information.Alternatively, user Equipment can be according to the EPDCCH for the detection that succeeds form, first in the first control channel logic unit of acquisition The sequence number of control channel logic unit after control channel logic unit immediately, after the first antenna port immediately second The sequence number of antenna port, and at least one determination of the offset indicated in EPDCCH the second control channel resource.It is optional Ground, user equipment can be according to the transmission mode of the PDSCH scheduled in EPDCCH, the first control channel logic units of acquisition In first control channel logic unit after control channel logic unit immediately sequence number, after the first antenna port The sequence number of the second antenna port immediately, and at least one determination of the offset indicated in EPDCCH second control channel Resource.
For example, user equipment can be according to the PDSCH scheduled in the EPDCCH for the detection that succeeds form or EPDCCH Transmission mode, the antenna port information of the first antenna port, in the offset indicated in offset and EPDCCH at least The sequence number of control channel logic unit immediately after one kind, and first control channel logic unit, determine this second Control channel resource.When the form for the EPDCCH that success detects is the first form, such as DCI format 1A, user equipment root According to the antenna port information of the first antenna port, after offset, and first control channel logic unit immediately The sequence number of control channel logic unit, determine the second control channel resource；When the form for the EPDCCH that success detects is second During form, such as DCI format 2C, offset and this first control that user equipment is indicated in EPDCCH according to offset The sequence number of control channel logic unit after channel logic unit processed immediately, determines the second control channel resource.Work as success When PDSCH scheduled in the EPDCCH of detection is the first transmission mode, such as TM10, user equipment is according to offset, in EPDCCH The sequence number of control channel logic unit after the offset of instruction, and first control channel logic unit immediately, really The fixed second control channel resource.When the PDSCH scheduled in the EPDCCH that success detects is the second transmission mode, such as TM9, use Family equipment according to the antenna port information of the first antenna port, offset, and first control channel logic unit it The sequence number of control channel logic unit immediately afterwards, determine the second control channel resource.
User equipment can also be according to the biography of the PDSCH scheduled in the EPDCCH for the detection that succeeds form or EPDCCH Defeated pattern, the serial number information of the first control channel logic unit, offset, the offset indicated in EPDCCH and this second At least one of sequence number of antenna port, determine the second control channel resource.When the form for the EPDCCH that success detects is During the first form, such as DCI format 1A, user equipment is according to the serial number information of the first control channel logic unit, skew Amount, and the sequence number of second antenna port, determine the second control channel resource；When the form for the EPDCCH that success detects is During the second form, such as DCI format 2C, user equipment is according to the serial number information of the first control channel logic unit, offset, And the offset indicated in EPDCCH, determine the second control channel resource.When scheduled in the EPDCCH that success detects When PDSCH is the first transmission mode, such as TM10, user equipment is according to the serial number information of the first control channel logic unit, skew Measure, the offset indicated in EPDCCH, determine the second control channel resource.When scheduled in the EPDCCH that success detects When PDSCH is the second transmission mode, such as TM9, user equipment is according to the serial number information of the first control channel logic unit, skew Amount, and the sequence number of second antenna port, determine the second control channel resource.
It should be understood that the property of uplink feedback ACK/NACK information can be improved using the transmission diversity scheme SORTD of two antennas Energy., it is necessary to have a frequency expansion sequence, and the expansion on the two antennas on each antenna for user equipment uses SORTD Frequency sequence is different, then modulates the frequency expansion sequence in different antennae with same ack/nack signal, and respectively this two Sent on individual antenna, so as to realize uplink feedback ACK/NACK information, as shown in Fig. 6 (B).
It should also be understood that HARQ detailed process can be as follows：In descending scheduling, user equipment needs to detect E-PDCCH And corresponding PDSCH.If E-PDCCH is detected successfully, then information of the user equipment just in E-PDCCH goes demodulation pair The PDSCH answered, then, user equipment need uplink feedback PDSCH demodulation result.If PDSCH demodulation is correct, then user Equipment feeding back ACK information represents that user equipment has had correctly received the data of transmission to eNB, so as to eNB can carry out it is new The transmission of data block；Conversely, user equipment feeds back nack message to eNB, represent that data are not properly received, it is necessary to which eNB is retransmitted The data.If E-PDCCH is not correctly detected, then user equipment is considered as not being scheduled to the PDSCH of oneself, so as to Up also without any feedback, i.e. discontinuous transmission (Discontinuous Transmission, referred to as " DTX ").
