Embodiment 1

[0186] Example 1: The terminal is not configured with CSI masking

[0187] Assuming that the terminal is currently in long DRX (long DRX), such as image 3 As shown, the PDCCH is received before the end of the on duration Timer, the DRX MAC CE is scheduled, and the terminal is switched from long DRX to short DRX (short DRX).

[0188] In this case, if CSI masking is not configured:

[0189] The PDCCH content carries the UL grant, then the length of the ambiguous period is equal to the PDCCH processing time;

[0190] Otherwise, the length of the fuzzy period is set to K0+K1+MAC CE processing time.

[0191] Among them, the calculation method of each parameter value is as follows:

[0192] Among them, the value of K0 can be obtained in the following ways:

[0193] According to the RRC configuration, when calculating the fuzzy period, the value of K0 always takes the maximum K0 value of the RRC configuration; or

[0194] The value of K0 is related to whether the BWP is changed...

Embodiment 2

[0203] Embodiment 2: The terminal is configured with CSI masking

[0204] Suppose the terminal is currently in long DRX, such as Image 6 As shown, the PDCCH is received before the end of the on duration Timer, the DRX MAC CE is scheduled, and the terminal is switched from long DRX to short DRX.

[0205] In this case, if CSI masking is configured:

[0206] No matter what the PDCCH scheduling content is, the ambiguous period length T3 is equal to K1+MAC CE processing time.

[0207] The calculation method of each parameter value is as follows:

[0208] There are several ways to get the value of K1:

[0209] According to the RRC configuration, when calculating the fuzzy period, the value of K1 always takes the maximum K1 value of the RRC configuration; or

[0210] The value of K1 is calculated according to the fixed value of 1ms;

[0211] The MAC CE value can be obtained in the following ways:

[0212] If the MAC CE parsing cannot be completed within K1, the MAC CE is fixed...

Embodiment 3

[0215] Example 3: Fixed Fuzzy Period Length

[0216] like Figure 8 As shown, it is assumed that the terminal is currently in long DRX, receives the PDCCH before the end of the on duration Timer, schedules the DRX MAC CE, and allows the terminal to switch from long DRX to short DRX.

[0217] In this case, the length of the fuzzy period is set to K0+K1+MAC CE processing time.

[0218] The calculation method of each parameter value is as follows:

[0219] There are several ways to get the value of K0:

[0220] According to the RRC configuration, when calculating the fuzzy period, the value of K0 always takes the maximum K0 value of the RRC configuration; or

[0221] The value of K0 is related to whether the BWP is changed. When calculating the fuzzy period, the value of K0 is the duration of the change of BWP, that is, K0 is calculated according to 2ms;

[0222] There are several ways to get the value of K1:

[0223] According to the RRC configuration, when calculating the ...

Abstract

The embodiment of the invention provides a fuzzy period length determination method, a terminal and network side equipment. The method comprises: a terminal determines a fuzzy period length, the fuzzyperiod length corresponds to a physical downlink control channel (PDCCH) processing time, or the fuzzy period length corresponding to a media access control unit (MAC CE) processing time; and the terminal determines whether to send an uplink signal at the current moment according to the received control message, and the difference between the receiving time of the control message and the currentmoment is greater than or equal to the length of the fuzzy period. According to the method of the invention, the communication performance of the wireless communication system can be improved, and unnecessary blind detection of network side equipment is avoided.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method for determining the length of an ambiguity period, a terminal and a network side device. Background technique [0002] In order to support the terminal to save power, the wireless communication system introduces a Discontinuous Reception (DRX) mechanism. In the DRX mechanism, the terminal does not continuously monitor the control channel, but monitors the control channel part of the time. The time may be referred to as active time (Active Time). In practical applications, when the terminal adopts the DRX mechanism, multiple timers can be started, such as: on-duration timer (On duration Timer), uplink discontinuous reception retransmission timer (UL drx-Retransmission timer), downlink discontinuous reception timer Retransmission timer (DLdrx-Retransmission timer) and discontinuous reception inactivity timer (drx-Inactivity timer), when any timer is run...
