Problems solved by technology

[0005] If asynchronous HARQ is used, the base station will asynchronously send an uplink retransmission instruction through the PDCCH after decoding the uplink data error. At this time, the user equipment may be in the silent period and does not monitor the PDCCH, and the UE does not know when to switch to During the activation period to monitor the PDCCH, this will lead to the failure of the uplink retransmission indication to be received correctly, resulting in problems such as transmission failure of the uplink retransmission indication, long retransmission delay or failure to retransmit

Embodiment 1

[0102] Such as figure 2 As shown, this embodiment provides an information processing method, the method comprising:

[0103] Step S110: when receiving an uplink transmission instruction, start a first timer;

[0104] Step S120: when the first timer times out, start a second timer;

[0105] Step S130: within the time counted by the second timer, monitor the physical downlink transmission control channel PDCCH.

[0106] The information processing method described in this embodiment can be applied to a UE. The uplink transmission instruction mentioned in the step S110 may be carried in the PDCCH information sent on the PDCCH channel. The uplink transmission indication is used to instruct the UE to perform uplink data transmission, and in this case, the base station will receive the data sent by the UE.

[0107] In step S110, after the uplink transmission indication is received, a first timer is started, and the first timer may be an uplink hybrid automatic repeat request tim...

Embodiment 2

[0154] Such as Figure 5 As shown, this embodiment provides an information processing method, the method comprising:

[0155] Step S210: Configure the first timer and the second timer to form configuration information; wherein, the configuration information is used to control the user equipment to start the first timer and the second timer respectively after receiving the uplink transmission instruction ;

[0156] Step S220: Send the configuration information to the user equipment.

[0157] The information processing method described in this embodiment can be applied to a base station. In this embodiment, the first timer and the second timer are dynamically configured by the base station, and form configuration information. For example, the base station configures and forms the configuration information based on a communication protocol or based on an instruction from an upper layer network element.

[0158] In step S220, the configuration information is sent to the UE. In...

example 1

[0234] There are three configuration methods for the base station to configure the UL HARQ RTT Timer for each retransmission process of the UE. Method 1: configure a HARQ RTT timer-ul for a certain HARQ process, the timer includes two parts, a fixed part HARQ RTT timer-ulc, and a time offset offset. If the HARQ RTT timer-ul times out, start DRX-RetransmissionTimer-ul. The DRX-RetransmissionTimer-ul here is the aforementioned second timer. The UL HARQRTT Timer-ulc here can be regarded as the aforementioned first timer. Of course, in specific implementation, the entire HARQ RTT timer-ul may also be regarded as the first timer.

[0235] The HARQ RTT timer-ulc is defined as: when the UE receives a PDCCH indicating uplink transmission, it starts the HARQ RTT Timer-ulc, and the first timer counts until it times out. Offset starts at the stop time of HARQ RTT Timer-ulc,

[0236] The time offset may be offset1 or offset2. Which offset (offset1 or offset2) the UE uses depends on t...

Abstract

The embodiment of the invention discloses an information processing method, user equipment and base station. The method includes starting a first timer when receiving an uplink transmission instruction; when the first timer is overtime, starting a second timer; and within the timekeeping time of the second timer, monitoring a Physical Downlink Transmission Control Channel (PDCCH).

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an information processing method, user equipment and a base station. Background technique [0002] Data transmission is usually bursty, with data transmission for a period of time, but no data transmission for a long period of time in the next period. When there is no data transmission, the user equipment will be able to reduce power consumption by stopping receiving the monitoring and detection of the Physical Downlink Control Channel (PDCCH), thereby prolonging the standby time, so Discontinuous Reception (Discontinuous Reception) is proposed. , DRX) transmission mechanism. [0003] The basic mechanism of DRX is to configure a DRX cycle for a user equipment (User Equipment, UE) in a radio resource connected state. Such as figure 1 As shown, the DRX cycle is composed of an active period and a silent period: during the active period, the user equipment monitors an...
