Description

Discontinuous reception control method and device

Technical Field

The invention relates to the field of communication, in particular to a discontinuous reception control method and a discontinuous reception control device.

Background

In a Long Term Evolution (LTE) system, a protocol architecture of a User Equipment or a User Equipment (UE) side User plane according to a related technology is shown in fig. 1. From bottom to top, the protocol layer is divided into the following protocol layers: a Physical layer (PHY), a Media Access Control (MAC), a Radio Link Control (Radio Link Control, RLC), and a Packet Data Convergence (PDCP). The PHY layer mainly transmits information to the MAC layer or a higher layer through a transmission channel; the MAC layer mainly provides data transmission and is responsible for wireless resource allocation through a logical channel, and completes functions of Hybrid automatic repeat request (Hybrid ARQ, HARQ for short), Scheduling (SCH for short), priority processing and Multiplexing and demultiplexing (MUX for short), Discontinuous Reception (DRX for short) for controlling the UE to discontinuously monitor and receive corresponding physical channel signals and data, and the like; the RLC layer mainly provides segmentation and retransmission services for user and control data; the PDCP layer mainly completes the transfer of user data to the RRC or an upper layer of the user plane.

In order to save power of the terminal, a Discontinuous Reception (DRX) technique is used, and the terminal may periodically monitor a Physical Downlink Control Channel (PDCCH) according to the configuration. The DRX technique is determined jointly by these parameters of the RRC configuration: onduration timer, DRX-inactivity timer, DRX-retransmission timer, mac-contentionsolutiontimer, the long DRX-Cycle, drxStartOffset, drxShortCycleTimer, shortDRX-Cycle (short DRX loop length). In addition, for some specific processes, for example, after receiving a newly transmitted schedule, such as a downlink retransmission, for example, an uplink retransmission, such as a non-contention random access downlink data waiting, for example, a collision resolution process, such as a Scheduling Request (SR) process, etc., the terminal needs to continuously detect the PDCCH for a period of Time outside the DRX cycle, so that an Active Time (Active Time) of DRX is defined, and the terminal needs to detect the PDCCH without special conditions during the Active Time. The activation time of this DRX is shown in fig. 2, and for the above-mentioned procedure, and the configuration of DRX, an irregular activation time is formed.

In order to provide a higher data rate for a mobile user, a Carrier Aggregation (CA) technology is introduced, and after entering a connected state, a UE may simultaneously communicate with a source base station through a plurality of component carriers (e.g., CC1, CC2), and introduce a Primary serving Cell (Pcell) and a Secondary serving Cell (Scell). In the subsequent stage of carrier aggregation, due to the increase of the data volume, the number of scells may be increased, for example, to 4, the scenario may also be widened, for example, a problem that a Remote Radio Head (RRH) and a repeater (repeater) are supported, and a Tracking Area (TA) cannot be solved, so that a plurality of TAs may be introduced. For convenience of management, the serving cells using the same TA are classified into one TA group. At this time, the TA group including the Pcell is a primary TA group (pTAG for short), and the TA group not including the Pcell is a secondary TA group (sstag for short). Because a plurality of service cells are in the same base station, the protocol architecture of the user plane is not changed, and the same DRX mechanism is adopted for different service cells. A terminal supporting carrier aggregation is called a CAUE.

Due to the requirement of network deployment, a plurality of base stations may be deployed nearby, and the time delay between the base stations is very short, so that carrier aggregation of cells between the base stations is possible. However, since the cells of multiple base stations perform carrier aggregation, the conventional carrier aggregation technology cannot be reused completely.

Aiming at the problem that the adjustment of the activation duration of the DRX activation state cannot be realized when the carrier aggregation is carried out among cells under different base stations in the related technology, an effective solution is not provided at present.

Such as a method for discontinuous reception control when a terminal enters a forced sleep state. The terminal detects the downlink HARQ feedback of the current UE continuously for a specified number of times, such as 10 times, detects DTX or uplink continuously for a specified number of times, such as 3 times, and the UE is forced to enter a sleep state when DCI0 is lost, and informs the base station 2. On the contrary, when the terminal detects the current UE downlink HARQ feedback continuously for a specified number of times, such as 10 times, and detects DTX or uplink continuously for a specified number of times, such as 3 times, in the cell 3, the UE forcibly enters the sleep state to notify the base station 1 when the DCI0 is lost.

When the SR is detected in the DRX sleep period, after DCI0 is issued, the primary carrier starts an Inactive timer of the primary carrier and starts an SR virtual verification timer, and simultaneously informs a Flag (SRTimeRFlag, the Flag is 0, which indicates that the SR virtual verification timer stops, and 1 indicates that the SR virtual verification timer is running), the Inactive timer of the secondary carrier is restarted after the secondary carrier receives the Flag, but the secondary carrier does not activate the DRX (namely the downlink scheduler prohibits scheduling), and when the primary carrier receives the CRCOK, the secondary carrier is informed to activate the downlink scheduler according to whether the Inactive timer runs or not. And when the SR virtual detection timer runs overtime, the auxiliary carrier Flag is notified to be 0 and the Inactive timer is stopped.

The base station 1 receives the SR sent by the terminal, learns that the terminal enters the SR suspension time, restarts the Inactive timer, and simultaneously informs the base station 2, and the base station 2 restarts the Inactive timer after receiving the SR; in addition, the base station 1 sends the DCI0 to the terminal, and after receiving the confirmation message from the terminal, if the Inactive timer is still running, the base station 2 is notified that the Inactive timer is running, so that normal scheduling can be performed; if the Inactive timer has stopped, the base station 2 is notified that the Inactive timer has stopped, and normal scheduling cannot be performed. The base station 1 also knows that the suspension of the SR is finished at the time T6, and simultaneously notifies the base station 2, and after receiving the notification, the base station 2 stores the relevant information. When the Inactive timer on the base station 1 stops, the base station 2 is informed that the Inactive timer stops, and the base station 1 stops the Inactive timer after receiving the information.

Optionally, before the step S302, a discontinuous reception DRX command sent by the first base station and/or the second base station may be received, where the discontinuous reception DRX command is at least used to indicate a cycle type that the terminal is in a DRX active state, and the cycle type includes: and acquiring the starting time of the terminal entering a DRX activation state according to the DRX command.

Such as in a discontinuous reception control method when the terminal receives a DRX command. The terminal receives the DRX command sent by the base station 1, and stops the current onduration timer (supervision timer) and DRX-inactivity timer (DRX prohibition timer). At this time, if the short DRX cycle is configured, the terminal starts a drxShortCycleTimer (short DRX timer) and re-enters the short DRX cycle, otherwise, re-enters the long DRX cycle.

If the terminal receives the Long DRX command, the terminal stops a drxShortCycleTimer (short DRX timer) and reenters the Long DRX period.

And meanwhile, the terminal informs the base station 2 that the terminal receives the information of the DRX command or the Long DRX command, or informs the base station 2 that the base station 1 sends the information of the DRX command or the Long DRX command to the terminal when the base station 1 sends the DRX command to the terminal.

And if the terminal enters the short DRX period, the terminal calculates the time for the terminal to enter the DRX active state according to the current system frame number and subframe number, and the configured drxStartOffset and shortDRX-Cycle.

And if the terminal enters the long DRX period, the terminal calculates the time for the terminal to enter the DRX active state according to the current system frame number and subframe number, and the configured drxStartOffset and longDRX-Cycle.

In an example of this embodiment, in order to solve the above problem, a new user plane protocol architecture is further proposed, as shown in fig. 10, a data radio bearer is divided among a plurality of base stations (MeNB), that is, data of one data radio bearer is transmitted through a plurality of base stations, where the plurality of base stations include a primary base station (P-eNB) and at least one secondary base station (S-eNB). Wherein the P-eNB includes at least a primary serving cell (PCell) of a terminal (UE) carrier aggregation cell and may include one or more secondary serving cells (scells) of the UE carrier aggregation cell. The S-eNB contains one or more scells of the UE carrier aggregation cell. As can be seen from fig. 4, the PDCP layer and the RLC layer exist only in one base station, but the MAC layer exists in each base station, wherein the MAC layer on the P-eNB includes all functions of the MAC layer including a data packet function, and the MAC layer on the S-eNB includes at least the data packet function. It should be noted that the above-mentioned architecture is one of the methods for solving the above-mentioned problems, and does not exclude other protocol architectures, and the present invention is not limited to only adopting the above-mentioned protocol architecture.

In the above example and alternative embodiments, the time instants of Tx (e.g., T1, T2, … … T9) may be identified by a frame number and a subframe number. If the terminal is configured with the cell 1 and the cell 3, the cell 4 performs carrier aggregation, and the operation procedures are similar and will not be described again.
