Description

A kind of group scheduling feedback method, base station and user equipment

Technical field

The present invention relates to field of communication technology more particularly to a kind of group scheduling feedback methods, base station and user equipment.

Background technique

In long term evolution (English: Long Term Evolution, in referred to as: LTE) Release 8 (referred to as: R8) system, base station (English: eNodeB, it is referred to as: eNB) to carry out communication and data on the same carrier wave to transmit with user equipment (English: User Equipment, abbreviation: UE).It may include the Physical Downlink Control Channel (English: Physical Downlink Control Channel of oneself in each subframe by the UE that base station is dispatched to, referred to as: PDCCH), PDCCH can be descending scheduling distribution (English: DL_Assignment) or uplink scheduling authorization (English: UL_grant), carry instruction Physical Downlink Shared Channel (English: Physical Downlink Shared Channel in PDCCH respectively in both cases, referred to as: PDSCH) or Physical Uplink Shared Channel is (English: Physical Uplink Shared Channel, referred to as: P The scheduling informations such as time-frequency resource allocating USCH).After UE is received in PDCCH search space and is decoded PDCCH, downlink data can be received by PDSCH accordingly or upstream data is sent by PUSCH, UE can be to downlink data feeding back uplink affirmative acknowledgement (English: Acknowledge later, referred to as: ACK)/negative response (English: Negative Acknowledge, referred to as: NACK), or base station can be to upstream data feeding back downlink ACK/NACK, wherein, downlink ACK/NACK is also physical mixed automatic re-transmission indicating channel (English: Physical Hybrid ARQ Indicator Channel, referred to as: PHICH).If the uplink feedback information of UE or the downlink feedback information of base station are NACK, then base station or UE can initiate to retransmit accordingly, this process is called hybrid automatic repeat-request (English: Hybrid Automatic Repeat Request, abbreviation: HARQ).

Wherein, PDSCH or PUSCH that PDCCH is dispatched with it, PDSCH corresponding uplink ACK/NACK and the corresponding PHICH of PUSCH have certain timing relationship, i.e. HARQ sequential relationship.Specifically, the PDSCH that DL_Assignment is dispatched with it in the same subframe, and The PUSCH that UL_grant is dispatched with it, PDSCH corresponding uplink ACK/NACK, and the corresponding PHICH of PUSCH is not the same subframe (because base station or UE require certain processing time, this time interval is typically no less than 4 subframes).Specifically, in frequency division duplex (English: Frequency Division Duplex, referred to as: FDD) in system, as shown in Figure 1, it is assumed that UE has received the PDSCH of DL_Assignment and its scheduling at the n moment, then UE can be in n+4 moment feeding back uplink ACK/NACK, if UE feedback is NACK, so base station can retransmit PDSCH not less than selection after 4 subframes, because downlink is asynchronous HARQ procedure, i.e. the re-transmission of base station does not strictly observe the interval of 4 subframes.Similarly, as shown in Figure 2, assuming that UE has received UL_grant at the n moment, so UE will send corresponding PUSCH at the n+4 moment, correspondingly, base station can feed back PHICH to UE at the n+8 moment, if base station feedback is NACK, so UE can retransmit PUSCH at the n+12 moment, because uplink mainly uses synchronous HARQ process, i.e., the interaction that base station and UE all follow 4 subframes is spaced.

As shown in figure 3, when base station is that multiple UE dispatch identical data simultaneously, in order to know the reception condition of this scheduled multiple UE, needing to distribute dedicated feedback channel resources for each UE in existing unicast schedule technology.Due to the UE that has may feeding back ACK, the case where some UE may feed back NACK, and the configuration mode of this feedback channel resources interferes with each other caused by can preventing the information difference fed back by multiple UE.But the feedback channel resources of the configuration mode of this dedicated feedback channel resource occupancy are more, signaling overheads is larger, are particularly unsuitable for the transmitting scene of broadcast and multicast.

As shown in fig.9, the process that base station carries out group scheduling to UE is as follows in the embodiment of the present invention:

Step 901: base station determines the UE in a grouping.

Specifically, the grouping information that the base station can be reported according to UE, to determine the UE in the grouping.Alternatively, the grouping information for the UE that the base station can also be sent according to equipment of the core network, to determine the UE in the grouping.

Step 902: the base station is that the UE in the grouping configures feedback channel resources.

Wherein, the base station can configure identical feedback channel resources for the UE in the grouping, or the UE in the grouping configures different feedback channel resources.For example, the UE in the grouping can be separated into different feedback groups by the base station, belong to the UE of the same feedback group using identical feedback channel resources, belongs between the UE of different feedback groups then using different feedback channel resources.

Specifically, base station is the feedback channel resources of the UE configuration in the grouping, can have but be not limited to following two allocation plan:

Scheme one,

The base station is that each UE in the grouping only configures NACK feedback channel resources, sends NACK when determining the received error in data for the UE in the grouping to the base station.

Under this configuration mode of scheme one, the base station can also indicate the UE in the grouping when determining that the received data are correct by the configuration information of feedback channel resources, without sending ACK to the base station.

Scheme two,

The base station is that each UE in the grouping configures any combination in following channel resources:

This configuration mode based on scheme two, the base station can have following four configuration method to the UE in the grouping: one, only configuring ACK feedback channel resources and NACK feedback channel resources；Two, ACK feedback channel resources and reference power launch channel resource are only configured；Three, NACK feedback channel resources and reference power launch channel resource are only configured；Four, ACK feedback channel resources, NACK feedback resources and reference power launch channel resource are configured.

Step 903: the base station notifies the configuration information of the feedback channel resources in the grouping UE。

Optionally, the configuration information of feedback channel resources can be sent to the UE in the grouping by the base station by common signal channel.

Step 904: UE of the base station into the grouping sends data.

UE carries out downlink data reception, and whether correct and feedback channel resources the allocation plan of data information based on the received, it is determined whether sends feedback information or sends which kind of feedback information.

For example, when received downlink data information is correct, UE does not feed back any information under the configuration mode of above scheme one；When received downlink data information errors, UE feeds back NACK using specified NACK feedback channel resources.And under the configuration mode of above scheme two, when received downlink data information is correct and is configured with ACK feedback channel resources, UE uses specified ACK feedback channel resources feeding back ACK；When received downlink data information errors and when being configured with NACK feedback channel resources, UE feeds back NACK using specified NACK feedback channel resources；When having received downlink data and being configured with reference power launch channel resource, UE sends reference signal to base station using reference power launch channel resource.

Step 905: the base station receives the feedback information of the transmission of the UE in the grouping on the feedback channel resources, and the feedback information is used to indicate the reception condition of the data.

Specifically, if using the first allocation plan in above-mentioned steps 902, then the base station can receive the NACK of the transmission of the UE in the grouping on specified NACK feedback channel resources when the UE in the grouping receives error in data.Since the UE in the grouping uses identical NACK feedback channel resources, the power for the NACK that the base station receives is the superposition for the power that all UE for erroneouslying received downlink data in the grouping are sent.

If using second of allocation plan in above-mentioned steps 902, since the UE in the grouping is using any combination in identical ACK feedback channel resources, identical NACK feedback channel resources and identical reference power launch channel resource, therefore the power for the ACK that the base station receives on ACK feedback channel resources is the superposition for the power that all UE for having correctly received downlink data are sent in the grouping, and the power for the NACK that the base station receives on NACK feedback channel resources is institute in the grouping The superposition for the power that the wrong UE for receiving downlink data is sent, the power for the reference signal that the base station receives in reference power launch channel resource are then the superpositions for the power that all UE for receiving downlink data are sent.

Further, before step 904, the base station can also configure identical scrambling code for the UE in the grouping, and the scrambling code is notified to the UE in the grouping.

Specifically, if using the first allocation plan in above-mentioned steps 902, then the base station can configure a kind of scrambling code for each UE in the grouping, for scrambling to the NACK that UE is fed back；If, then the base station can configure one or more scrambling codes for each UE in the grouping, ACK, NACK or reference signal for feeding back to UE are scrambled using second of allocation plan in above-mentioned steps 902.

Correspondingly, the base station can receive the feedback information after the scrambling of scrambling code described in the use of the transmission of the UE in the grouping in step 905.

Step 906: the base station is according to the power of the feedback information, it is determined whether retransmits to the data.

It is corresponding with two kinds of allocation plans of feedback channel resources in above-mentioned steps 902, there is following two method also to determine the need for carrying out data re-transmission to the UE in the grouping:

Method one

If using the first allocation plan in above-mentioned steps 902, the so described base station determines the power of the NACK received on the feedback channel resources first, then judge whether the power of the NACK is greater than preset threshold value, if, then the data are retransmitted, otherwise, the data are not retransmitted.

It should be noted that, the base station determines whether that carrying out data re-transmission generally can be, but not limited to following several situations according to the power of the NACK received: whether the power whether power of the NACK is greater than preset threshold value or the NACK meets preset condition etc..The embodiment of the present invention is illustrated whether the power of the NACK is greater than for preset threshold value such case, is not constituted a limitation of the invention.

For example, as shown in Figure 10, the base station by the UE in group 1 be further separated into 2 it is different Feedback group, each UE in feedback group 1 are all made of NACK feedback channel resources 1, and each UE in feedback group 2 is all made of NACK feedback channel resources 2.When the superposition power for the NACK that the UE of any feedback group (such as feedback group 1) in the grouping is sent is judged greater than preset threshold value in the base station, data re-transmission just is carried out to the UE of feedback groups all in the grouping.

Method two

If using second of allocation plan in above-mentioned steps 902, so according to the base station be UE configuration in the grouping be ACK feedback channel resources, NACK feedback channel resources and reference power launch channel resource which kind of combination, method two can also be subdivided into following three kinds of modes:

Mode one: if the base station is configured with ACK feedback channel resources and NACK feedback channel resources for the UE in the grouping, the so described base station determines the power of the power of ACK received on the ACK feedback channel resources, the NACK received on the NACK feedback channel resources respectively first, then according to the power of the power of ACK and NACK, it is determined whether retransmitted to the data.

For example, the base station can first determine the ratio value of the power of ACK and the power of NACK perhaps the power of the power of ACK and the power of ACK and NACK and value ratio value or other ratio values；When then judging whether the ratio value is greater than preset threshold value, if so, being retransmitted to the data, otherwise, the data are not retransmitted.

The ratio value of the power of the power and NACK of ACK described herein characterizes the ratio value of the quantity that the UE of ACK is sent in the grouping and the quantity for the UE for sending NACK.

Mode two: if the base station is configured with NACK feedback channel resources and reference power launch channel resource for the UE in the grouping, the so described base station determines the power of the power of the NACK received on the NACK feedback channel resources, the reference signal received in the reference power launch channel resource respectively first, then according to the power of the power of reference signal and NACK, it is determined whether retransmitted to the data.

For example, the base station can first determine the ratio value or other ratio values of the ratio value of the power of reference signal and the power of the NACK perhaps power of the difference and NACK of the power of the power and NACK of reference signal；When then judging whether the ratio value is greater than preset threshold value, if so, being retransmitted to the data, otherwise, the data are not retransmitted.

Mode three: if the base station is configured with ACK feedback channel resources and reference power launch channel resource for the UE in the grouping, the so described base station determines the power of the power of the ACK received on the ACK feedback channel resources, the reference signal received in the reference power launch channel resource respectively first, then according to the power of the power of ACK and reference signal, it is determined whether retransmitted to the data.

For example, the base station can first determine the ratio value or other ratio values of the ratio value of the power of ACK and the power of the reference signal perhaps difference of the power of the power of ACK and the power of reference signal and ACK；When then judging whether the ratio value is greater than preset threshold value, if so, being retransmitted to the data, otherwise, the data are not retransmitted.

Theoretically, the base station is according to any two power in the power of the power of ACK, the power of NACK and reference signal, the ratio value for being properly received the UE of downlink data and garbled-reception downlink data in the grouping can be calculated, determines whether to need to carry out data re-transmission.

As shown in figure 11, the base station is that the UE in the grouping is configured with ACK feedback channel resources, NACK feedback channel resources and reference power launch channel resource, and the base station can take any mode in above-mentioned three kinds of modes to determine the need for carrying out data re-transmission at this time.In practical applications, the power of reference signal can be also used for the calibration of the power to the power and NACK of ACK.

Corresponding with method flow shown in Fig. 9, in the embodiment of the present invention, the process that UE receives the group scheduling of base station is as shown in figure 12:

Step 1201:UE receives the configuration information of the feedback channel resources of base station notice, determines that the base station is the feedback channel resources of UE configuration according to the configuration information.

Further, the UE is also possible to that the scrambling code of the base station notice can be received.Subsequent, the UE scrambles feedback information using the scrambling code, and the feedback information after scrambling is sent to the base station.

Optionally, before the configuration information of feedback channel resources that base station notice is received in UE, the grouping information of the UE can be reported to the base station by the UE, and the base station is enabled to determine the grouping of the UE ownership.

Optionally, the configuration information of the received feedback channel resources of the UE can be is connect by common signal channel It receives.The common signal channel configures feedback channel resources for UE of the base station into grouping.

Optionally, the configuration information of the received feedback channel resources of the UE can indicate the UE without feedback, and the UE is determined according to the instruction without feedback.

Wherein, the UE can be identical with the feedback channel resources of other UE configuration in the grouping that the UE belongs to and scrambling code, can not also be identical.Such as, if the base station more fine-grained feedback group of further division in the grouping that the UE belongs to, the feedback channel resources and scrambling code then configured between the UE and other UE for belonging to same feedback group with the UE are identical, and the feedback channel resources and scrambling code configured between the UE and other UE for belonging to different feedback groups from the UE are different.In another example if other UE in the grouping that the base station belongs in the grouping that the UE belongs to without further division feedback group, the UE and the UE are all made of identical feedback channel resources and scrambling code.

In the embodiment of the present invention, the base station that the UE is determined is the feedback channel resources of its configuration, can specifically have but be not limited to following two allocation plan:

Scheme one,

The UE determines that the feedback channel resources that the base station is the UE configuration are NACK feedback channel resources, and the NACK feedback channel resources send NACK when determining the received error in data to the base station for the UE.

Scheme two,

The UE determines that the base station be the feedback channel resources of UE configuration is any combination in following channel resources:

Step 1202: the UE receives the data that the base station is sent.

Step 1203: the UE is directed to the reception condition of the data, passes through the feedback channel resources Feedback information is sent to the base station.

The UE carries out downlink data reception, and whether correct and feedback channel resources the allocation plan of data information based on the received, it is determined whether sends feedback information or sends which kind of feedback information.

Specifically, when the UE determines that the received data are correct, not sending feedback information to the base station under the configuration mode of above scheme one；When the UE determines the received error in data, NACK is sent to the base station by the NACK feedback channel resources.

And under the configuration mode of above scheme two, if the UE determines that the feedback channel resources that the base station is the UE configuration are ACK feedback channel resources and NACK feedback channel resources, then when the UE determines that the received data are correct, ACK is sent to the base station by the ACK feedback channel resources；When the UE determines the received error in data, NACK is sent to the base station by the NACK feedback channel resources.If the UE determines that the feedback channel resources that the base station is the UE configuration are ACK feedback channel resources and reference power launch channel resource, then when the UE determines that the received data are correct, ACK is sent to the base station by the ACK feedback channel resources；When the UE, which is determined, receives the data, preset reference signal is sent to the base station by the reference power launch channel resource.If the UE determines that the feedback channel resources that the base station is the UE configuration are NACK feedback channel resources and reference power launch channel resource, then when the UE determines the received error in data, NACK is sent to the base station by the NACK feedback channel resources；When the UE, which is determined, receives the data, preset reference signal is sent to the base station by the reference power launch channel resource.If the UE determines that the feedback channel resources that the base station is the UE configuration are ACK feedback channel resources, NACK feedback channel resources and reference power launch channel resource, then when the UE determines that the received data are correct, ACK is sent to the base station by the ACK feedback channel resources；When the UE determines the received error in data, NACK is sent to the base station by the NACK feedback channel resources；When the UE, which is determined, receives the data, preset reference signal is sent to the base station by the reference power launch channel resource.

The base station determines whether according to the UE and with the power of the UE other UE for belonging to same grouping feedback information sent to progress data re-transmission.When data are initiated to the UE in the grouping in the base station to be retransmitted, the UE for receiving error in data in the grouping before needs to re-start data receiver.

In summary, the technical solution that group scheduling is carried out to UE that the various embodiments described above of the present invention provide, base station are that the UE in same group distributes identical feedback channel resources and scrambling code by being grouped to UE, UE is scheduled as unit of group, to reduce the feedback channel resources and signaling of occupancy.

In LTE system, Web vector graphic Multicast Broadcast Single Frequency Network (English: Multimedia Broadcast multicast service Single Frequency Network, referred to as: MBSFN) mode transmission multimedia broadcast multi-broadcasting business (English: Multimedia Broadcast Multicast Service, abbreviation: MBMS) business.MBSFN includes the point-to-multipoint control channel of the MBMS (English: Multicast Control Channel for being used for transmission control signaling, referred to as: MCCH), with the MBMS point-to-multipoint service channel (English: MBMS Traffic Channel for being used for transmission business datum, referred to as: MTCH), the two is mapped on Multicast Channel (English: Multicast Channel, abbreviation: MCH).When the information of MCCH changes, need to notify UE.And MCCH has a modification period (English: Modification Period, referred to as: MCCH MP), it include one or more repetition periods in each MCCH MP, base station can only start to modify MCCH message in MCCH MP boundary, and the MCCH message that each repetition period sends in same MCCH MP is identical.The length of MCCH MP is the integral multiple of repetition period.If network side determines to update the content of MCCH, needs to mention previous MCCH MP notice UE, the content of MCCH is then updated behind the boundary for crossing MCCH MP.Wherein MCCH Notification of Changes passes through MBMS radio network temporary identifier (English: MBMS Radio Network Temporary Identification, referred to as: M-RNTI) it is sent to UE, including the MBSFN zone list of 8 bits, the corresponding region MBSFN of each bit, UE can determine which corresponding MCCH in the region MBSFN changes according to this list.

In existing system, all in the same intra-cell transmission, two class business transmit data using different subframes respectively by the way of the time-division for MBMS business and non-MBMS business.The distribution situation of MBMS business subframe is notified UE, UE that can determine all MBMS business subframes according to system message by network side by system broadcasts.Wherein MBSFN sub-frame is divided into MBSFN symbol and non-MBSFN symbol again, and the MBMS symbolic component in MBSFN sub-frame is used for transmission MBMS business and control information, and non-MBSFN symbolic component is used for transmission MCCH Notification of Changes and schedule upstream traffic.And MCCH Notification of Changes can only be sent in MBSFN sub-frame.

However, the various bandwidth configuration that LTE cell is supported, includes 1.4M, 5M, 10M, 20M these types situation, specific bandwidth is by broadcast message notice to UE.When bandwidth of cell is 1.4M, the non-MBSFN symbol that MBSFN sub-frame includes is 2, this 2 symbols include 30 resource units in total, and sends MCCH Notification of Changes and need 36 resource units.This, which will lead to UE, can not receive MCCH Notification of Changes.

In order to solve the problems, such as that bandwidth of cell possibly can not be received MCCH Notification of Changes by UE in limited time, the embodiment of the invention also provides a kind of MCCH message to send and read method, base station and UE.
