Currently, an LTE system introduces an aggregation of 5 carriers at most, that is, enbs can configure 5 carriers for UEs at most, each carrier has a 20M bandwidth, and 5 carriers reach 100M bandwidth, for this reason, when a Physical Downlink Control Channel (PDCCH) schedules a carrier configured for a UE, Downlink Control Information (DCI) carried by the PDCCH provides a 3-bit field to indicate which carriers the DCI is for, and since the 3-bit field can assign any digits from 0 to 7, a carrier index number of 8 carriers can be indicated by the 3-bit field at most, and a scheduling requirement of 5 carriers is satisfied.

In order to further increase the peak data rate and the system throughput, Release-13 of the Long term evolution-Advanced (LTE-a) system introduces large-scale Carrier Aggregation (Massive Carrier Aggregation), the maximum number of carriers that can be aggregated can reach 32, that is, enbs can configure 32 carriers for UEs at most, however, the existing Carrier scheduling method can only support scheduling of 8 carriers at most, and cannot support scheduling of 32 carriers at most.

The UE can send and receive data on the activated carriers only after the carriers are activated, but there is a special case that the primary carrier configured for the UE by the eNB does not need to be activated before the carrier reconfiguration, and the primary carrier is in the activated state.

In addition, the applicable scenarios of the technical solution provided by the embodiment of the present invention include, but are not limited to, scenarios in which the UE only receives and transmits data from base stations in time periods, and the carriers used by the UE are provided by base stations, as shown in fig. 1, and the second scenarios in which the UE simultaneously receives and transmits data from two or more base stations, and the carriers used by the UE are provided by multiple base stations, as shown in fig. 2, a Dual-Connectivity (DC) scenario belongs to a typical scenario in the second scenario.

The carrier groups may have other downlink carriers without a PDCCH in addition to at least th downlink carriers, and may have other uplink carriers without a PUCCH in addition to at least th uplink carriers.

In an alternative embodiment, the th carrier group includes at least th uplink carriers, the th uplink carrier having PUCCH configuration, wherein the uplink primary carrier configured for the UE is the th uplink carrier.

In the carriers activated for the UE, both the uplink primary carrier and the downlink primary carrier must exist, but the uplink secondary carrier does not exist , or only the downlink secondary carrier may not have the uplink secondary carrier, or the number of the downlink secondary carrier and the number of the uplink secondary carrier are not and are equal to each other, generally indicates that the number of the downlink secondary carrier is greater than or equal to the number of the uplink secondary carrier.

The DCI includes a carrier index indication field (CIF), the CIF includes 3 bits, an index of a carrier indicated by the CIF is C, Cmod8 is x, and x is an indication value of the CIF.

Step 102, the eNB sends the PDCCH on the th downlink carrier which is activated for the UE.

The DCI carried by the PDCCH is used to schedule the activated carriers in the carrier group in which the th downlink carrier is located.

Step 103, the UE receives the PDCCH on the activated th downlink carrier, and transmits and receives data on the activated carrier under the indication of the DCI carried by the received PDCCH.

In the embodiment of the invention, at least two carrier groups are configured for the UE through the eNB, the number of uplink carriers and the number of downlink carriers of each carrier group do not exceed 8, the at least two carrier groups comprise at least carrier groups, the carrier group comprises activated carriers, and the carrier group comprises at least downlink carriers configured with PDCCH (physical Downlink control channel).

Example two

The embodiment of the present invention provides carrier management methods, and referring to fig. 4, the method includes:

step 201, the eNB sends th reconfiguration message to the UE.

The eNB configures at least two carriers for the UE, wherein the at least two carriers comprise at least uplink carriers and at least downlink carriers, the at least two carriers are divided into at least two carrier groups, the number of uplink carriers and the number of downlink carriers of each carrier group do not exceed 8, and each carrier group comprises at least th downlink carriers, and the PDCCH is configured on the th downlink carrier.

Wherein the carriers in each carrier group are different.

The total number of carriers configured by the eNB for the UE may be greater than 8, or may not be greater than 8.

Each carrier group comprises at least () th downlink carriers, wherein the th downlink carrier in the carrier groups is a downlink main carrier of the UE, the uplink main carrier and the downlink main carrier of the UE are in the same carrier groups, and the th downlink carrier in the carrier groups except the carrier group where the main carrier is located is a downlink auxiliary carrier.

In an alternative embodiment, each carrier group includes at least st th uplink carriers, the th uplink carrier having PUCCH configuration, the th uplink carrier in the carrier group where the primary carrier is located may be an uplink primary carrier configured for the UE.

As an optional embodiment, each intra-carrier group carrier has the same Timing Advance (TA), but it is not limited whether the TA of different intra-carrier groups is the same. The TA is used to indicate the timing relationship between the uplink transmission time and the downlink arrival.

Wherein, the UE receives th reconfiguration message sent by the eNB.

It should be noted that, before sending the th reconfiguration message, the eNB may configure multiple carriers for the same UE multiple times, and configure several carriers for the UE every times.

The PDCCH carries DCI, and the DCI is used for scheduling activated carriers in a carrier group where th downlink carriers which are activated for the UE are located.

The DCI includes a CIF, the CIF includes 3 bits, an index number of a carrier indicated by the CIF is C, Cmod8 is x, and x is an indication value of the CIF.

Specifically, if the value range of the carrier index is 0-7, the index of the carrier indicated by the CIF is the same as the indicated value of the CIF, and if the value range of the carrier index is 0-31, the calculated value modulo 8 of the carrier index indicated by the CIF is the same as the indicated value of the CIF.

Step 202, the eNB sends th carrier activation indication message to the UE.

The th carrier activation indication message is used to indicate activated and/or deactivated secondary carriers for the UE, the activated secondary carriers for the UE are inactive carriers among carriers configured by the eNB for the UE, and the deactivated secondary carriers for the UE are activated carriers among carriers configured for the UE.

In the existing protocol, generally adopts Activation/Deactivation (MAC) media Access Control (CE) signaling to indicate Activation and Deactivation of carriers, and Activation/Deactivation MAC CE signaling provides 7-bit fields as indicating bits of the secondary carriers, (from the right), the 1 st bit corresponds to the 1 st secondary carrier, and the 2 nd bit corresponds to the 2 nd secondary carrier.

The th carrier Activation indication message may be obtained by updating the Activation/Deactivation MAC CE signaling, for example, expanding the Activation/Deactivation MAC CE and occupying a 1-bit reserved bit.

The th carrier activation indication message comprises secondary carrier indication bits, wherein the secondary carrier indication bits have two formats, the th format comprises T bits, T is equal to the maximum aggregated carrier number, the ith bit corresponds to the ith carrier, i is 0, 1, 2, 1, T-2 or T-1, if the T bits are not whole bytes, reserved bits can be allowed for completing the whole bytes, the second format comprises 8 bits, the index number of the carrier corresponding to the jth bit in the 0 th bit to the 7 th bit in the 8 bits is C ', C' mod8 ═ j, and j is 0, 1, 6 or 7.

For the carrier groups except the carrier group of the main carrier, the first activated carrier group is the downlink auxiliary carrier with the PDCCH and the uplink auxiliary carrier with the PUCCH, for the carrier groups except the carrier group of the main carrier, if the downlink auxiliary carrier with the PDCCH is deactivated, all downlink auxiliary carriers in the carrier group are deactivated, and if the uplink auxiliary carrier with the PUCCH in the carrier group except the carrier group of the main carrier is deactivated, all uplink auxiliary carriers in the carrier group are deactivated.

Since the Activation/Deactivation MAC CE signaling belongs to the upper Layer signaling of the Physical Layer (PHY for short), updating the Activation/Deactivation MAC CE signaling will not affect the structure of the PHY.

In conjunction with the format of the th carrier activation indication message, the present embodiment provides two ways to transmit the th carrier activation indication message.

transmission mode, which can adopt the second format, when adopting the second format, the activation indication message can be transmitted only in the carrier group where the main carrier is located, and when the carrier to be activated is distributed in a plurality of carrier groups, the eNB sequentially transmits a plurality of carrier activation indication messages according to the carrier group identification sequence to indicate the carrier to be activated in different carrier groups, or transmits the format activation indication message in the carrier group where the main carrier is located, and only needs to transmit times, so that the activation and deactivation indication of different carrier groups can be indicated.

In a second transmission mode, when the activated downlink carrier exists in the carrier group where the carrier to be activated is located, the eNB may send a th carrier activation indication message through the activated downlink carrier in the carrier group where the carrier to be activated is located, so as to activate the carrier to be activated in the carrier group.

In the third transmission mode, when there are no active carriers in the th carrier group, the th transmission mode is used to transmit the carrier activation indication message, and when there are active carriers in the th carrier group, the second transmission mode is used to transmit the carrier activation indication message.

Wherein, the UE receives th carrier activation indication message sent by the eNB.

Step 203, the eNB sends the PDCCH on the th downlink carrier that has been activated for the UE.

After the eNB activates the carrier for the UE, the eNB may determine DCI carried by the PDCCH according to the activated carrier, and after the DCI is determined, the eNB sends the PDCCH on the th downlink carrier activated for the UE.

Step 204, the UE receives the PDCCH on the activated th downlink carrier, and transmits and receives data on the activated carrier according to the indication of the DCI carried by the received PDCCH.

Step 205, the UE reports a Power Headroom Report (PHR for short) of each activated carrier.

This step is optional and is only reported if the PHR can report.

The UE can report PHR of each activated carrier in a mode through three modes, report PHR of each activated carrier in a second mode through any activated uplink carriers, report PHR of each activated carrier in a th carrier group through any activated uplink carriers in a carrier group where a main carrier is located, and report PHR of each activated carrier in a th carrier group on activated uplink carriers in each th carrier group, wherein the three modes operate independently, carriers are written out in an explicit protocol, or the eNB configures the PHR reporting mode adopted by each UE.

In the existing protocol, PHRMAC CE signaling is similar to the format of Activation/Deactivation MAC CE signaling, a 7-bit field is provided as a carrier indicator bit, PHR of 7 auxiliary carriers can be indicated at most, the format of the PHR MAC CE signaling can be updated to obtain updated PHR indication signaling, and the format of the updated PHR indication signaling can refer to the format of carrier Activation indication information.

Wherein, the eNB receives PHR of each activated carrier reported by the UE.

Step 206, the UE reports the Channel State Information (CSI) of the activated downlink carrier.

The UE may report the CSI of the activated downlink carrier to the eNB by using an existing CSI reporting mechanism. In an Advanced Long Term Evolution-Advanced (LTE-a) system, periodic CSI reporting is actively reported by a UE, and the UE feeds back on a PUCCH configured by a primary uplink carrier.

For example, assuming that a preset reporting period of the CSI of the downlink carrier CC1 is 5 and a preset offset is 1, the reporting period of the CSI of the CC1 is subframes 1, 6, 11, 16, 21, 26, and so forth, the UE feeds back the CSI of the CC1 on the subframes 1, 6, 11, 16, 21, 26, and so forth, and assuming that the preset reporting period of the CSI of the downlink carrier CC2 is 2 and the preset offset is 0, the reporting period of the CSI of the CC2 is subframes 2, 4, 6, 10, 12, 14, 16, and so forth, the UE feeds back the CSI on the subframes 2, 4, 6, 10, 12, 14, 16, and so forth, and it can be seen that the UE needs to feed back the CSI of the CC 26 and CSI of the CC2 simultaneously on the subframes 366, but the CSI of two downlink carriers is prioritized and only sorted by the priority of the downlink carrier CSI of the PUCCH loaded on the subframes 3, 16, and so that the UE is preferentially sorted by two downlink carriers according to the priority of the CSI of the downlink carrier, the CSI of which the CSI of the PUCCH loaded carrier 1 and the PUCCH loaded downlink carrier are prioritized carrier, and the priority of the PUCCH loaded downlink carrier of which is 2, the highest priority, the lowest priority, but the priority of the downlink carrier of which.

Wherein the eNB receives CSI of the activated downlink carrier.

In the embodiment of the invention, an eNB configures at least two carrier groups for UE, the number of uplink carriers and the number of downlink carriers of each carrier group do not exceed 8, the at least two carrier groups comprise at least carrier groups, the carrier group comprises carriers which are activated for the UE, the carriers which are activated for the UE in the carrier group comprise at least downlink carriers, the downlink carriers are configured with PDCCHs, the eNB configures the PDCCHs on the downlink carriers which are activated for the UE, and the PDCCHs carry DCI which is used for scheduling the activated carriers in the carrier group where the downlink carriers which are activated for the UE are located, so that the DCI in the existing protocol has a 3-bit field for indicating carrier index numbers, the 8 carriers can be scheduled at most, and the number of the uplink carriers and the number of the downlink carriers of each carrier group do not exceed 8, therefore, the UE and the eNB can realize that a large number of carriers can be scheduled and used after being aggregated on the premise of keeping the structure of the existing DCI unchanged.

The eNB receives CSI of the activated downlink carrier reported by the UE.

The second set of methods is as follows.

Step 510, the UE sends a second carrier indication message to the eNB.

The second carrier indication message is used for indicating the updated secondary carrier set to be scheduled to the eNB.

The second carrier indication message may also be dedicated signaling for RRM or CQI report, in which the UE does not report the measurement value of the replaced carrier to the eNB any more, after receiving the RRM or CQI report, the eNB deletes the carrier without the measurement value from the secondary carrier set to be scheduled, and selects activated secondary carriers whose measurement values are higher than the predetermined limit to add to the secondary carrier set to be scheduled by the eNB, so as to obtain an updated secondary carrier set to be scheduled by the eNB.

Wherein the eNB receives a second carrier indication message.

Step 511, the eNB schedules at least secondary carriers in the primary carrier and the updated set of secondary carriers to the UE.

The downlink main carrier is configured with a PDCCH, and the PDCCH carries DCI.

Step 512, the UE receives the PDCCH on the downlink primary carrier, and transmits and receives data on the carrier scheduled to the UE according to the indication of the DCI carried by the received PDCCH.

Step 513, the UE reports the CSI of the activated carrier.

Here, step 513 is the same as step 206 in the second embodiment, and is not described herein again.

Wherein the eNB receives CSI of the activated carrier.

The eNB configures a large number of carriers for the UE and selects K auxiliary carriers from the activated auxiliary carriers for scheduling, and because the eNB may aggregate the large number of carriers configured to the UE, the eNB may flexibly select carriers activated and scheduled for the UE from the large number of carriers configured to the UE, for example, when a channel condition of a carrier actually scheduled to the UE becomes poor, the carrier with the poor channel condition may be replaced, and other carriers configured to the UE may be scheduled to the UE.

The third set of methods is as follows.

EXAMPLE six

The embodiment of the present invention provides carrier management methods, and referring to fig. 8, the method includes:

step 601, the eNB sends a third carrier activation indication message to the UE.

The carriers activated for the UE comprise at least second uplink carriers, and the second uplink carriers are configured with Physical Uplink Shared Channel (PUSCH) resources.

Wherein the UE receives the third carrier activation indication message.

Step 602, the UE reports the CSI of each activated downlink carrier on the PUSCH resource of the activated second uplink carrier.

And the eNB receives the CSI of each activated downlink carrier reported by the UE on the PUSCH resource of the second uplink carrier activated for the UE.

In this embodiment, the CSI of the downlink carrier is reported on the PUSCH resource by the UE, and since the resource on the PUSCH is relatively abundant, the CSI of a large number of downlink carriers can be borne, so that the problem of insufficient resources caused when the CSI of up to 32 downlink carriers is reported on the PUCCH configured by the main uplink carrier can be solved, and meanwhile, collision caused when the CSI of all downlink carriers is reported on the PUCCH configured by the main uplink carrier is avoided, and more CSI of the downlink carriers can be reported.

EXAMPLE seven

The embodiment of the present invention provides carrier management methods, and referring to fig. 9, the method includes:

step 701, the eNB sends a third reconfiguration message to the UE.

The third reconfiguration message is used for indicating the carriers configured for the UE, the carriers configured for the UE include at least second uplink carriers, and PUSCH resources are configured on the second uplink carriers.

simple signaling overhead calculations are performed, that is, the maximum bit number of CSI reported by downlink carriers in subframes is 11 × 2(2 code words), and the total bit number of CSI reported by 32 downlink carriers is 11 × 2 × 32 ═ 704 bits, whereas the maximum bit number that can be sent in 1 Physical Resource Block (PRB) is 712 bits, that is, the maximum Transport Block Size (TBS) is used, so even if only 1 PRB is reserved at each cycle point of the PUSCH Resource, CSI of 32 downlink carriers can be released, and the number of downlink carriers in most cases cannot reach the maximum 32, so that the problem of insufficient capacity does not exist.

Wherein the UE receives the third reconfiguration message.

Step 702, the eNB sends a third carrier activation indication message to the UE.

The activated carrier for the UE comprises at least second uplink carriers.

The UE receives a third carrier activation indication message.

Step 703, the UE obtains the reporting period point of the CSI of each activated downlink carrier according to the reporting period and the offset of the CSI of the preset downlink carrier.

The reporting period and the offset of the CSI of each downlink carrier may be preset. The offset refers to a subframe of the starting position of the reported CSI. According to the reporting period and the offset, the reporting period point of the CSI of each downlink carrier can be determined. The reporting period point of the CSI of the downlink carrier may refer to each reporting subframe of the CSI of the downlink carrier in this embodiment.

For example, assuming that the preset reporting period of the CSI of the downlink carrier CC1 is 5 and the preset offset is 1, the reporting period point of the CSI of the CC1 is subframes 1, 6, 11, 16, 21, 26, and. For another example, assuming that the preset reporting period of the CSI of the downlink carrier CC2 is 2 and the preset offset is 0, the reporting period point of the CSI of the CC2 is subframes 2, 4, 6, 10, 12, 14, 16.

Step 704, the UE reports the CSI of each activated downlink carrier on the PUSCH resource of the second uplink carrier activated for the UE according to the obtained reporting cycle point of the CSI of each activated downlink carrier.

Therein, step 704 can be divided into two cases.

, the reporting period point of the CSI of the activated downlink carrier carried by the PUSCH resource in the current period is located between the transmission point of the PUSCH resource in the first periods and the transmission point of the PUSCH resource in the current period, that is, the UE reports the CSI of the downlink carrier with the reporting period point located between the transmission point of the PUSCH resource in the first periods and the transmission point of the PUSCH resource in the current period on the PUSCH resource in the current period.

By reporting the CSI of the downlink carrier on the PUSCH through the UE, the problem of insufficient resources caused by reporting the CSI which can reach 32 downlink carriers at most on the PUCCH configured by the main uplink carrier can be solved, meanwhile, the collision brought by reporting the CSI of all the downlink carriers through the PUCCH configured by the main uplink carrier is avoided, and the CSI of each downlink carrier can be reported.

Compared with the case, the second case reduces the number of reported CSI of the downlink carriers, and solves the problem of insufficient resources caused by reporting CSI which can reach 32 downlink carriers at maximum on a PUCCH configured by a main uplink carrier in a fixed degree.

It should be noted that, when the UE reports the CSI in the manner provided in step 704, the UE reports the CSI according to the periodic point of the PUSCH resource, instead of reporting the CSI according to the reporting periodic point. In addition, when reporting the CSI by using the method provided in step 704, the UE may report the CSI on the carrier configured with the PUCCH according to the reporting cycle point of the CSI.

The fourth set of methods is as follows.
