Priority of Chinese Patent Application, the entire contents of which is incorporated herein by reference. Technical field

The present invention relates to the field of wireless communications, and in particular, to a method, system, and device for scheduling and reporting uplink control information. Background technique

In the Long Term Evolution (LTE) system, the Physical Uplink Control Channel (PUCCH) is used to transmit Uplink Control Information (UCI) after synchronization. The uplink control information transmitted on the PUCCH mainly includes an uplink scheduling request (SR), a Hybrid Automatic Repeat reQuest-ACK (HARQ-ACK) information, and a periodic channel shield indication of the user equipment (UE). Channel Quality Indicator, CQI) information. The downlink HARQ-ACK information may be further divided into semi-persistent scheduling HARQ-ACK information, dynamic scheduling HARQ-ACK information, and acknowledgement/negative response repetition (ACK/NACK repetition) information according to different allocated PUCCH resources. . The UCI information and the resource location, configuration parameters, and resource indication parameters corresponding to the information are shown in Figure 1.

The PUCCH resource in an uplink subframe mainly includes two parts, one is a resource occupied by PUCCH format 1/la/lb, and the other is a resource occupied by PUCCH format 2/2a/2b.

The resources occupied by PUCCH formatl/la/lb are as follows:

One part is the resource occupied by the PUCCH that dynamically schedules ACK/NACK feedback; the other part refers to the resources required for transmitting the dedicated scheduling request (D-SR), semi-persistent scheduling ACK/NACK, and ACK/NACK repetition in the uplink subframe. The physical layer is represented as the parameter ^, which is a cell-level parameter, and the calculation expression is:

N ^l P ^w UCCH = n ' ^l P ^m UCCH, persis + ^T n ^rl P ^(l U ⁾ CCH, schreq + n "P ^(l U ⁾ CCH, repetition .

The towel: puccH, _p . represents the number of PUCCH(l) resources used for semi-persistent scheduling feedback in an uplink subframe;

Indicates the number of PUCCH(1) resources used to transmit the scheduling request in one uplink subframe; puccH, repetition. Indicates the number of PUCCH(1) resources used by ACK/NACK repetition.

For PUCCH format 1/la/lb, one physical resource block (PRB) can The number of UEs carried ^^-^^ is calculated according to the following formula:

Where: ^ra - ^{pt / CCff} is the cyclic shift sequence length of PUCCH, ^L CS - PUCCH ^{= ]} ~ ² ., _othogonal - _seq is the number of sequences, and for PUCCH (l), is a cyclic shift sequence The cyclic shift interval can be 1 2 3 . According to the result provided by the link simulation, take ~, if the number of UEs is relatively small, you can take =3 ₀

According to the above formula:

If = 1 N

Then = 36 if = 2 = 18 if = 3 N

Then = 12

The resources occupied by PUCCH format2/2a/2b are as follows:

The resources required for transmitting CQI in the uplink subframe, the physical layer is represented by the parameter ^, and the reserved period of the cell CQI transmission resource set depends on the number of UEs that need to use the periodic CQI feedback in the system (using the operation management system)

(Operation & Maintenance, 0&M) is associated with the ^NuE - ^{C0NNECT of the ί} and the CQI feedback period of the UE (represented by the parameter ^{^^ of the} ^O &M configuration).

For transmitting SR information on the PUCCH, it is actually transmitting D-SR information. For a UE configured with a D-SR resource, the resources of the D-SR are periodically repeated, and the D-SR can be guaranteed by configuring the maximum D-SR transmission number DSR_TRAN_MAX through the Radio Resource Control (RRC) layer. Reliability.

The downlink HARQ-ACK information for the UE is usually transmitted on the PUCCH resource. When a PUCCH resource and a PUSCH resource exist in a UE in a subframe, the information on the PUCCH resource will be in a Physical Uplink Shared Channel (Physical Uplink Shared Channel, Transfer on PUSCH). Since downlink scheduling supports two types of scheduling modes: semi-persistent scheduling HARQ-ACK and dynamic scheduling HARQ-ACK. For the downlink semi-persistent scheduling HARQ-ACK mode, the PUCCH resources used are completely configured by the RRC layer of the base station, and the HARQ-ACK mode is dynamically scheduled in the downlink, and the used resources are designed according to the timing of the scheduling signaling, the RRC layer configuration of the base station, and the dynamic scheduling. The CCE resource index used by the downlink scheduling signaling is jointly determined, and in order to solve the problem of insufficient uplink coverage or reliability of HARQ-ACK transmission, it can be guaranteed by repeated transmission of downlink HARQ-ACK information, and resources used for ACK/NACK repetition are repeated. The number of times and the like are all configured by the base station RRC layer.

In the process of implementing the present invention, the inventors have found that the following technical problems exist in the prior art:

According to the analysis of the existing scheme, it can be known that the D-SR in the UCI information can ensure the transmission reliability of the D-SR by configuring the maximum number of transmission times DSR_TRAN_MAX of the D-SR through the RRC layer, and the HARQ-ACK can guarantee the ACK/NACK repetition. Transmission reliability. At present, there is no specific scheme for guaranteeing the reliability of periodic CQI information transmission. When the PUCCH coverage is insufficient, the transmission performance of the periodic CQI information cannot be guaranteed. Summary of the invention

In order to improve the transmission performance of the uplink control information, the embodiment of the present invention provides a method for scheduling and reporting uplink control information. In this method, the base station determines that the user equipment needs to be scheduled by using a semi-persistent scheduling (SPS) manner. After the uplink control information is periodically reported, the user equipment is scheduled to periodically update the uplink control information through the PUSCH, and the user equipment periodically reports the uplink control information through the PUSCH according to the scheduling of the base station.

Referring to FIG. 2, the method for scheduling uplink control information according to the embodiment of the present invention includes the following steps: Step 20: The base station determines that the user equipment periodically reports the uplink control information through the PUSCH.

The SPS parameter value, and the configuration signaling that carries the uplink SPS parameter value is sent to the user equipment;

Step 21: The base station determines that the user equipment periodically reports the MCS level and the resource location used for the uplink control information, and sends the scheduling signaling that carries the information of the MCS level and the resource location to the user equipment. The uplink control information is periodically reported to the base station according to the scheduling signaling.

Preferably, before the step 20, the base station determines whether to enable the PUSCH resource of the SPS to carry the periodic uplink control information according to the load condition of the PUCCH and/or the interference condition. For example, when the load of the PUCCH reaches a preset load threshold, it is determined to enable the scheme; or, when the IoT value indicating the interference condition of the PUCCH reaches a preset IoT threshold, it is determined to enable the Alternatively, when the load of the PUCCH reaches a preset load threshold and the IoT value indicating the interference condition of the PUCCH reaches a preset IoT threshold, it is determined to enable the scheme.

Correspondingly, in step 20, after determining that the scheme is enabled, the base station determines, by using the PUSCH, the uplink SPS parameter value that is used by the user equipment to periodically perform the uplink control information, and sends the configuration signaling that carries the uplink SPS parameter value. Give the user device.

Preferably, after the base station determines to enable the scheme and determines the uplink SPS parameter value, the base station determines whether the user equipment is suitable for the scheme and whether the uplink SPS parameter value needs to be configured for the user equipment; for example, the user equipment reports through the PUCCH. When there is an idle available resource in the subframe used for the uplink control information, it is determined that the user equipment is suitable for the scheme; otherwise, it is determined that the user equipment is not suitable for the scheme; and the user equipment uses the inherent period to report the uplink through the PUSCH. If the control information does not cause a resource conflict, it is determined that the uplink SPS parameter value is not required to be configured for the user equipment. Otherwise, the reporting period needs to be re-determined, so that the user equipment does not generate a resource conflict by reporting the uplink control information through the PUSCH in the reporting period. The upper cycle is configured to the user equipment by using the uplink SPS parameter value, where the natural period is the period used by the user equipment to report the uplink control information through the PUCCH.

In step 20, after determining that the user equipment is suitable for the scheme and the uplink SPS parameter value needs to be configured for the user equipment, the base station determines the uplink SPS parameter value used by the user equipment to periodically report the uplink control information on the PUSCH, and carries the uplink SPS parameter value. The configuration signaling of the uplink SPS parameter value is sent to the user equipment.

In one case, when the user equipment does not have other services that need to be scheduled in the SPS mode, the base station uses the configuration signaling and the scheduling signaling to schedule only the user equipment to periodically report the uplink control information through the PUSCH.

In this case, the uplink SPS parameter value includes an uplink semi-persistent scheduling resource interval value, and the uplink semi-persistent scheduling resource interval value is: a time period value used by the user equipment to periodically report uplink control information on the PUCCH.

Correspondingly, in step 21, the base station determines the MCS level and the resource location used by the user equipment to periodically report the uplink control information through the PUSCH, and the specific implementation may be as follows:

First, the base station determines a transport block size (TB Size) according to the number of bits required to carry the uplink control information;

Then, the base station determines, according to the channel transmission condition of the user equipment, the user equipment to report the uplink control information.

MCS level;

Finally, the base station determines the location of the PRB used by the uplink control information of the user equipment according to the TB Size and the Modulation and Coding Scheme (MCS) level. In another case, when the user equipment has other services that need to be scheduled by the SPS, the base station also uses the configuration signaling and the scheduling signaling to simultaneously schedule the user equipment to periodically report data of other services through the PUSCH.

In this case, the uplink SPS parameter value includes an uplink semi-persistent scheduling resource interval value, and the uplink semi-persistent scheduling resource interval value is: a time period value used by the user equipment to periodically transmit data of other services on the PUSCH.

Correspondingly, in step 21, the base station determines that the user equipment periodically reports the uplink control information through the PUSCH, the used MCS level and the resource location, and the specific implementation may be as follows:

First, the base station determines the transport block size according to the BSR (Buffer Status Report) information reported by the user equipment, or determines the TB Size according to the BSR information and the number of bits required to carry the uplink control information. Then, the base station is configured according to the user equipment. The channel transmission condition determines the MCS level used by the user equipment to report the uplink control information;

Finally, the base station determines the location of the physical resource block PRB used by the user equipment uplink control information according to the TB Size and the MCS level.

For the above two cases, the uplink SPS parameter value includes but is not limited to one or any combination of the following parameters: the value of the null packet number of the uplink implicit release;

The uplink power control user equipment exclusive parameter value used for semi-persistent scheduling transmission;

Double interval configuration parameter value.

In step 20, the configuration signaling may be RRC signaling.

Preferably, in step 21, the base station may send, by using a physical downlink control channel (PDCCH), scheduling signaling that carries information of the MCS level and the resource location to the user equipment.

In the method, the uplink control information is: CQI information, or dedicated scheduling request (D-SR) information, or hybrid automatic repeat request confirmation feedback information of the SPS.

Referring to FIG. 3, an embodiment of the present invention further provides an uplink control information reporting method, which specifically includes the following steps: Step 30: A user equipment receives configuration signaling that carries an uplink SPS parameter value sent by a base station, and performs the uplink SPS parameter value. Save

Step 31: The user equipment receives the scheduling signaling of the information carrying the MCS level and the resource location sent by the base station, uses the MCS level and the resource at the resource location, and performs uplink control information on the physical uplink shared channel PUSCH according to the uplink SPS parameter value. Periodically reported.

In another case, when the user equipment has other services that need to be scheduled by using the SPS mode, the base station also uses the configuration signaling and the scheduling signaling to simultaneously schedule the user equipment to periodically report data of other services through the PUSCH. At this time, the user equipment transmits data of other services on the resource indicated by the resource location information carried in the scheduling signaling. Correspondingly, the uplink SPS parameter value includes an uplink semi-persistent scheduling resource interval value, and the uplink semi-persistent scheduling resource interval value is: a time period value used by the user equipment to periodically transmit data of the service on the PUSCH.

Specifically, the user equipment may use the puncturing mode to transmit uplink control information and data of other services on the resource indicated by the resource location information carried in the scheduling signaling.

In the method, the uplink SPS parameter value further includes, but is not limited to, one or any combination of the following parameters: an empty packet number of the uplink implicit release;

Double interval configuration parameter value.

In step 30, the configuration signaling may be RRC signaling.

In step 31, the user equipment may receive scheduling signaling through the PDCCH.

In the method, the uplink control information is: CQI information, or D-SR information, or HARQ-ACK feedback information of the SPS.

The invention will be specifically described below:

For the LTE system, when the uplink control channel coverage is insufficient, the periodic CQI transmission performance is not guaranteed. The present invention provides a method and apparatus for improving the reliability of the uplink control channel, that is, the PUSCH resource bearer period CQI information of the SPS. The method guarantees the reliability of its periodic CQI, and at the same time, this method can be extended to other UCI information with periodicity. This solution is suitable for both FDD and TDD systems.

The PUSCH resource bearer period of the SPS The basic implementation process of the CQI information scheme is shown in Figure 4A:

The first step is: the PUCCH resource management module of the base station MAC layer performs the activation decision of the CSTI information of the PUSCH resource bearer period of the SPS according to the historical PUCCH load condition and the interference condition, and determines whether the scheme needs to be enabled currently;

Step 2: After determining the scheme for activating the CQI information of the PUSCH resource bearer period of the SPS, the RRC layer determines whether the current UE is suitable for adopting the scheme and whether the corresponding semi-persistent scheduling parameter needs to be configured according to the actual situation of each UE. Then, according to the transmission QoS requirement of the periodic CQI, parameters such as a semi-persistent resource period are determined, and the configuration of the information element (IE) SPS-Config is completed;

The third step: the MAC layer performs the CQI information activation decision of the PUSCH resource bearer period of the SPS according to the design rule, and determines the TB size according to the service characteristics of the bearer when the semi-persistent resource is activated, and determines the MCS and the allocated uplink share according to the channel condition of the UE. Channel resources, complete the activation of semi-persistent resources.

The following is a detailed description of the SPS PUSCH resource bearer cycle CQI information method for each step: First, design the activation mechanism of the solution provided by the present invention:

The activation mechanism provided by the present invention is mainly for the case that the uplink control channel coverage is limited, and the periodic CQI information transmission performance is not guaranteed. After the above situation occurs, the PUSCH resource bearer period CQI of the SPS of the present invention is considered to be activated. Information programme.

In the second step, the UE uses the RRC layer configuration of the present invention:

If the network scenario meets the conditions of the CQI information plan of the PUSCH resource bearer period in which the SPS is activated, the current situation is determined.

Whether the UE is suitable for the solution, if applicable, the IE SPS-Config needs to be configured for the UE at this time.

The IE includes the following in the current standard:

Table 1

When configuring the parameters of the IE SPS-Config, the configuration of the uplink and downlink semi-persistent scheduling resource interval depends on the period of the current UE's periodic CQI. The configuration of the parameter will affect the timeliness of the CQI reporting of the UE period, and the semi-persistent resource interval. The configuration needs to take into account the arrival characteristics of the service data packet and the period size of the periodic CQI.

If the UE only has a periodic CQI, it is only necessary to consider resource allocation for the periodic CQI;

If the UE has both periodic CQI and semi-persistent scheduled services, it needs to consider the periodic CQI and other packet arrival characteristics. For example, the voice packet arrival interval of the VOIP (voice over IP, IP-based voice call) service activation period is about 20 ms, and the period of the general CQI is 20 ms, then the semi-persistent scheduling resource interval can be configured as the third step. The MAC layer applies the solution of the present invention:

After the RRC layer successfully configures the relevant information in the IE SPS-Config for the UE, the MAC layer can perform the semi-persistent resource activation decision according to the needs when performing data scheduling. In this case, the eNB side does not need to configure the periodic CQI resource for the UE, and only needs to schedule the periodic CQI according to the semi-persistent scheduling mode. The calling relationship of the PUSCH resource bearer period CQI information of the SPS is as shown in FIG. 4B, and the base station is in the subframe. n, will carry the MCS level and resource location letter After the DCI format 0 is scrambled by the SPS-RNTI, it is sent to the UE through the PDCCH, and the UE demodulates the MCS level and the resource location information of the PDCCH in the subframe n+4, and uses the MCS level and the location of the resource. The PRB resource reports the CQI information to the base station, and then reports the CQI information to the base station every 20 subframes.

The design of the specific activation mechanism is related to the goal of the algorithm design. The base station activates the semi-persistent scheduling through the PDCCH of the SPS C-RNTI, and determines the MCS and the allocated PRB resources of the UE. The MCS and the allocated PRB determine the current PRB data. Carrying capacity, ie TB size. According to the LTE standard, the TB size is obtained according to the number of allocated PRBs and the current MCS level search criteria defined by the UE. Therefore, determining the TB size determines the current MCS level of the UE and the number of PRB resources allocated for the UE.

(a) Determination of TB size: The determination of the TB size of each semi-persistent resource bearer needs to consider the characteristics of the semi-persistent scheduling transmission service, the configuration of the semi-persistent resource interval.

If the UE only has the periodic CQI, it only needs to consider the number of bits of the periodic CQI, about 20 bits. If the UE has both the periodic CQI and the semi-persistent scheduled service, the periodic CQI is transmitted in the PUSCH by the puncturing method. On the one hand, only consider the TB size of the semi-persistent scheduling service; on the other hand, the periodic CQI is used as a service to participate in resource allocation together with the data. At this time, it is necessary to consider the common data amount of the periodic CQI and other data packets. , to determine the TB size.

(b) Determination of MCS level: The supported MCS level is determined according to the channel transmission conditions of the UE. For the uplink, the base station performs CQI measurement and correction on the SRS sent by the UE, and determines the MCS level that the UE can currently support. In addition, since the MCS level generally does not change during the semi-persistent scheduling process, the uplink CQI information used here is the information after smoothing.

(c) Determination of the location of the PRB resource: Based on the TB size requirement and the MCS level currently supported by the UE, the number of PRBs required by the UE to activate the semi-persistent resource and the starting position of the PRB can be determined. The UE periodically reports the CQI information through the PUSCH by using the determined PRB and the subframe used when the CQI information is reported by the PUCCH.
