Description

Technical Field

In order to meet the increasing communication demand, technologies such as CA (carrier aggregation) and DC (dual-connectivity) are introduced in the standardization process of 3GPP to enable the UE to transmit data on multiple carriers simultaneously.
Taking DC as an example, fig. 1 is a schematic diagram of a dual connectivity structure in the prior art, as shown in fig. 1, in an LTE system, for a UE in a dual connectivity mode, an eNB with only one S1-MME connection between an MeNB and an MME is referred to as a primary eNB (i.e., MeNB), and another eNB is used to provide additional resources and is referred to as a secondary eNB (i.e., SeNB). Each eNB is capable of independently managing radio resources in the UE and the respective cell, and resource coordination between MeNB and SeNB is communicated via signaling messages over the X2 interface.

specifically, when the terminal UE configures multiple PDCCHs, the terminal acquires all PDCCHs configured therewith and enters the CDRX state, where it should be noted that the UE entering the CDRX state may be actively entering the CDRX state, or the base station may instruct the UE to enter the CDRX state. And for the base station indicating the UE to enter the CDRX state, the base station sends an instruction for entering the CDRX state to the UE, and the UE enters the CDRX state after receiving the instruction.
Step 202: and selecting one or more PDCCHs from the plurality of PDCCHs as target PDCCHs according to a preset strategy, and monitoring the target PDCCHs.

It should be noted that the target PDCCH may be one or multiple, but the number of target PDCCHs should be less than or equal to the total number of PDCCHs configured with the UE. The preset strategy can be issued to the UE by the base station, or can be actively formulated by the UE side.
According to the embodiment of the invention, one or more PDCCHs are selected from the plurality of PDCCHs as the target PDCCHs according to the preset strategy, and the target PDCCHs are intercepted, so that the number of the intercepted PDCCHs is reduced, and the energy consumption of the terminal is effectively reduced.

It should be noted that, if the preset policy includes multiple priorities, the UE performs priority ranking, and then selects the PDCCH corresponding to the highest priority or the PDCCHs corresponding to some higher priorities as the target PDCCH.
According to the embodiment of the invention, the PDCCH corresponding to the first priority is selected as the target PDCCH according to the preset strategy which is sent by the base station and comprises the priority information, and the monitoring is carried out, so that the monitoring quantity of the PDCCHs is reduced as much as possible on the premise of ensuring the communication performance, and the energy consumption of the UE is further reduced.
On the basis of the foregoing embodiment, the selecting one or more PDCCHs from the multiple PDCCHs as a target PDCCH according to a preset policy includes:
acquiring a carrier except a main service cell or a carrier except the main service cell and configured with a PDCCH, and deactivating the carrier except the main service cell or the carrier except the main service cell and configured with the PDCCH;
selecting a PDCCH in an active state from the plurality of PDCCHs as the target PDCCH.
Specifically, the terminal acquires a carrier other than a primary serving cell carrier or a carrier configured with a PDCCH other than the primary serving cell carrier, and performs deactivation processing on the acquired carrier, so that the carrier is in a deactivated state, and the primary serving cell carrier corresponding to the primary serving cell or the primary serving cell carrier and a carrier not configured with the PDCCH are in an activated state.
According to the embodiment of the invention, the carriers except the carrier of the main service cell or the carrier which is configured with the PDCCH and is except the carrier of the main service cell are deactivated in a targeted manner, and the PDCCH on the carrier in an activated state is selected as the target PDCCH, so that the number of the monitored PDCCHs is reduced, and the energy consumption of the UE is reduced.
On the basis of the above embodiment, the preset policy includes first indication information that is sent by the primary base station and deactivates carriers other than the primary serving cell carrier or carriers configured with the PDCCH other than the primary serving cell carrier;

After receiving the preset strategy, the UE deactivates carriers other than the primary serving cell carrier or carriers configured with a PDCCH other than the primary serving cell carrier according to the first indication information in the preset strategy, so that the carriers are in a deactivated state, and the primary serving cell carrier corresponding to the primary serving cell, or the primary serving cell carrier and the carriers not configured with the PDCCH are in an activated state.

Specifically, after acquiring all PDCCHs configured by the UE, the base station configures PDCCH configuration parameters for the UE according to the PDCCHs by using a preset rule, where the PDCCH configuration parameters are used to convert parameters required for a scheduling mode of the PDCCH when the UE enters a CDRX state, and after the UE needs to enter the CDRX state, the base station converts a scheduling mode of multiple carriers with PDCCHs into cross-carrier scheduling according to the received PDCCH configuration parameters, and schedules all carriers by using a primary serving cell PCell and/or a secondary serving cell SCell. After cross-carrier scheduling, the UE does not need to monitor the PDCCH on the scheduled carrier any more, thereby reducing the monitoring number of the PDCCH. The UE may receive an explicit indication of the base station and then transition to cross-carrier scheduling according to the configured PDCCH configuration parameters.
According to the embodiment of the invention, the PDCCH scheduling mode is converted into cross-carrier scheduling according to the received PDCCH configuration parameters, so that the monitoring number of the PDCCHs is reduced, and the energy consumption of the terminal is reduced.

and when the awakening state is recovered or the CDRX state is jumped out, activating the carriers except the main service cell carrier or the carriers except the main service cell carrier which are in the deactivated state and are provided with the PDCCH after receiving the second indication information.
Specifically, when the base station determines that the UE recovers the awake state or jumps out of the CDRX state, the base station sends second indication information to the base station, where the second indication information is used to indicate that the UE activates a carrier other than the primary serving cell carrier or a carrier configured with a PDCCH other than the primary serving cell carrier in the deactivated state. Therefore, when the UE recovers the awake state or jumps out of the CDRX state, and after receiving the second indication information, the carrier other than the primary serving cell carrier or the carrier configured with the PDCCH other than the primary serving cell carrier in the deactivated state is activated, so that uplink and downlink data can be normally transmitted.

Specifically, when the UE recovers from the sleep state in the CDRX state to the awake state or jumps out of the CDRX state, and after receiving a configuration recovery instruction sent by the main base station, the cross-carrier scheduling configuration of the target PDCCH currently corresponding to the UE is recovered to the PDCCH configuration before entering the CDRX state according to the configuration recovery instruction. It should be noted that the recovery configuration instruction may be issued by the base station to the UE, or may be actively configured by the UE, and the recovery configuration instruction includes parameter information required to recover the PDCCH configuration before entering the CDRX state.
According to the embodiment of the invention, when the awakening state is recovered or the CDRX state is jumped out, the PDCCH configuration corresponding to the terminal is recovered, so that normal data transmission can be ensured.
