Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
Fig. 1 is a flowchart illustrating some embodiments of a multi-carrier downlink transmission method according to the present disclosure.
As shown in fig. 1, the method of this embodiment includes:
in step 11, the base station configures a primary carrier and at least one (i.e., one or more) downlink auxiliary carriers as a cell resource, so that the downlink auxiliary carriers and the primary carrier form a logical cell.
Wherein, in order to enhance the downlink coverage, the frequency of the downlink auxiliary carrier is lower than that of the main carrier.
In some embodiments, the base station configures the primary carrier and the at least one downlink auxiliary carrier as one cell resource through higher layer signaling. For example, the base station adds configuration information of at least one downlink auxiliary carrier in a cell Resource to serving cell common information (serving cell configuration common) in Radio Resource Control (RRC) signaling, where the configuration information includes information such as a frequency point and a maximum number of downlink auxiliary carriers, and is expressed as:
supplementaryDownlinkConfigList--SEQUENCE(SIZE(1..maxNrofSDL))OF supplementaryDownlinkConfig
the supporteardownlinkconfigutlist indicates a configuration list of the downlink auxiliary carriers, the supporteardownlinkconfig indicates a configuration of the downlink auxiliary carriers, the SEQUENCE indicates a SEQUENCE number of the downlink auxiliary carriers, and the maxNrofSDL indicates a maximum number of the configured downlink auxiliary carriers. If maxNrofSDL is 7, it indicates that the cell has 7 downlink auxiliary carriers available for downlink transmission.
Based on the configuration in step 11, the subsequent base station may schedule at least one carrier from the cell resource for downlink data transmission, as detailed in steps 12-14.
In step 12, a User Equipment (UE) initiates an uplink access procedure to establish a higher layer connection, such as an RRC connection, with a base station.
In step 13, the base station configures carrier resources for the user equipment from cell resources of a serving cell in which the user equipment is located, where the carrier resources include a primary carrier and at least one (i.e., one or more) downlink secondary carriers.
The base station configures carrier resources for the user equipment from cell resources of a service cell where the user equipment is located through a high-level signaling, and informs the user equipment of the number of the carrier so as to indicate the carrier on which the user equipment carries out downlink transmission. For example, the base station adds configuration information OF at least one downlink secondary carrier in the carrier resources OF the ue in serving cell configuration information (ServingCellConfig) in the RRC signaling, for example, adds SEQUENCE (SIZE (1.. maxNrofSDL)) OF supportmentassociated downlink, and adds a number OF a downlink secondary carrier configured for the ue in supportmentassociated downlink, and if the number is 2, 3, it indicates that two downlink secondary carriers numbered 2 and 3 are configured for the ue from among 7 downlink secondary carriers OF the cell except for the primary carrier.
In step 14, the base station schedules one or more carriers for the ue from the carrier resources configured for the ue for downlink data transmission.
And the base station schedules one or more carriers for the user equipment from the carrier resources configured for the user equipment to carry out downlink data transmission through the physical layer control signaling. For example, the base station schedules one or more Downlink auxiliary carriers for the ue from carrier resources configured for the ue through Downlink auxiliary carrier scheduling Information added in DCI (Downlink Control Information) in a PDCCH (Physical Downlink Control Channel) signaling to perform Downlink data transmission.
For example, a downlink secondary carrier scheduling indicator (DL/SDL indicator, 3bits) is added to the DCI of the PDCCH to inform the UE of which downlink secondary carriers the base station performs downlink data transmission on, a downlink secondary carrier scheduling number (DL/SDL _ Sche _ Num, 3bits) may be added to the DCI of the PDCCH, and when a value is DL/SDL _ Sche _ Num equals to 1, it indicates that downlink transmission is performed on 1 downlink secondary carrier, and when a value is DL/SDL _ Sche _ Num equals to 3, it indicates that downlink transmission is concurrently performed on 3 downlink secondary carriers.
In step 15, according to the Control requirement, the base station adds an indication for activating or deactivating at least one downlink auxiliary carrier in a physical layer Control signaling PDCCH or a Media Access Control (MAC) layer signaling, so as to inform the user equipment of which downlink auxiliary carriers are activated or deactivated. This step may not be performed if there is no associated control requirement.
For example, the base station adds the activated or deactivated downlink auxiliary carrier list and the activation or deactivation indication of each downlink auxiliary carrier in the list to the signaling. For example, DL/SDL _ Active/reactive _ List- -SEQUENCE (SIZE (1.. maxNrofSDL)) OF SDL-InSchedulingCell; this variable is the list of activated and deactivated downlink auxiliary carriers; DL/SDL _ Active/inactive (1bits), when the value is DL/SDL _ Active/inactive equals to 1, it indicates to activate the corresponding downlink auxiliary carrier scheduling; and when the value is DL/SDL _ Active/inactive is 0, the corresponding downlink auxiliary carrier scheduling is deactivated.
By deactivating some downlink auxiliary carriers, it is beneficial to reduce the power consumption of the user equipment.
The downlink transmission performance is improved by configuring a plurality of carriers such as a main carrier and at least one downlink auxiliary carrier as a cell resource and scheduling at least one carrier from the cell resource for downlink data transmission, for example, downlink transmission rate and downlink throughput are improved by scheduling a plurality of carriers for downlink data transmission concurrently, and downlink coverage can be improved by scheduling a downlink auxiliary carrier with a lower frequency. Moreover, the multiple carriers for downlink scheduling belong to one logical cell, and different carriers in the existing downlink carrier aggregation technology belong to different logical cells, so the multi-carrier downlink transmission enhancement scheme can reduce inter-cell switching and improve user performance.
Fig. 2 is a schematic diagram of one example of a multi-carrier downlink transmission enhancement of the present disclosure. As shown in fig. 2, the cell resource includes a primary carrier (3.5GHz) and a secondary carrier (2.1GHz), the primary carrier (3.5GHz) is, for example, a TDD (Time Division Duplex) mode of 5G, and the secondary carrier (2.1GHz) is, for example, an FDD (Frequency Division Duplex) mode, where "D" denotes a downlink timeslot, "S" denotes a shared timeslot, "U" denotes an uplink timeslot, and "4R" and "2R" both denote receiving antennas. If the ue is located in the coverage of 3.5GHz (since the coverage of 2.1GHz is large, it is inevitably located in the coverage of 2.1GHz), the base station may schedule the downlink timeslot of the primary carrier for downlink transmission, may schedule the downlink timeslot of the secondary carrier for downlink transmission, and may also schedule the downlink timeslots of the primary carrier and the secondary carrier for downlink transmission at the same time. If the user equipment is not in the coverage range of 3.5GHz and is in the coverage range of 2.1GHz, the base station can schedule the downlink time slot of the auxiliary carrier for downlink transmission. Therefore, the downlink transmission performance such as the downlink coverage, the downlink transmission rate, the downlink throughput and the like of the 5G is improved.
The multi-carrier downlink transmission enhancement method can be combined with the multi-carrier uplink transmission enhancement method, so that the downlink transmission performance of 5G is improved, and the uplink transmission performance of 5G is also improved. For convenience of description, in the multi-carrier downlink transmission enhancement method, the secondary carrier is also referred to as a downlink secondary carrier; in the multi-carrier uplink transmission enhancement method, the secondary carrier is also referred to as an uplink secondary carrier.
Fig. 3 is a schematic diagram of one example of a multi-carrier uplink transmission enhancement of the present disclosure. As shown in fig. 3, the cell resources include a primary carrier (3.5GHz) and one secondary carrier (2.1GHz), as in fig. 2. If the UE is located in the coverage of 3.5GHz (since the coverage of 2.1GHz is large, the UE is inevitably located in the coverage of 2.1GHz), the base station may schedule the UE to perform uplink transmission in the uplink timeslot of the primary carrier, may also schedule the UE to perform uplink transmission in the uplink timeslot of the secondary carrier, and may also schedule the UE to perform uplink transmission in the uplink timeslots of the primary carrier and the secondary carrier at the same time. If the UE is not in the coverage of 3.5GHz and is in the coverage of 2.1GHz, the base station may schedule the UE to perform uplink transmission in the uplink timeslot of the auxiliary carrier. Therefore, the uplink transmission performances of 5G, such as uplink coverage, uplink transmission rate and uplink throughput, uplink feedback delay and the like, are improved.

As shown in fig. 4, the base station 40 of this embodiment includes: a memory 41 and a processor 42 coupled to the memory 41, wherein the processor 42 is configured to execute the multicarrier downlink transmission method in any of the foregoing embodiments based on instructions stored in the memory 41.
