Embodiment 1

[0113] The terminal side can pre-generate and statically store a table corresponding to the preset measurement value range of the measurement object and the suggested value of retransmission scheduling monitoring times. The measurement object can be but not limited to the serving cell RSRP and SINR measured by the terminal. In the process of data transmission, according to the current RSRP and SINR measured value look-up table to select the corresponding recommended value of retransmission scheduling monitoring times, when the measured values ​​of RSRP and SINR of the serving cell currently measured by the terminal meet a certain predicted measured value range , the terminal selects the recommended value of retransmission scheduling monitoring times corresponding to the range of predicted measurement values ​​as its own retransmission scheduling monitoring times. Or, when the measured values ​​of RSRP and SINR of the serving cell currently measured by the terminal respectively ...

Embodiment 2

[0132] The specific process of determining the number of retransmission scheduling monitoring times with the present invention is described below with an embodiment of a specific numerical value, and the specific steps are as follows:

[0133] a) Set the suggested value of the maximum retransmission scheduling monitoring times as Nmax, and the maximum uplink transmission times configured by the network in this embodiment is 5, then Nmax=4. In this embodiment, the cell edge is defined as RSRP=-110dBm and SINR=-3dB as the minimum measurement value, and the coverage excellent point is defined as RSRP≥-80dBm and SINR≥20dB, and RSRP=-80dBm and SINR=20dB as the maximum measurement value.

[0134] b) RSRP takes 2dBm as the step size, and selects 16 sampled measurement values ​​sequentially from -110dBm to -80dBm, which are respectively {-110, -108, -106, ..., -84, -82, -80}. The corresponding SINR selects 16 sampling measurement values ​​sequentially from -3dB to 20dB with a step siz...

Abstract

The present invention discloses a method and device for determining the number of retransmission scheduling monitoring, which is used to solve the problem in the prior art that the terminal low power consumption time is short and the power saving effect is poor due to the repeated interruption of the dormant cycle of the terminal monitoring the retransmission scheduling. The problem, the method is: according to each channel quality parameter measurement value currently obtained, the terminal respectively determines the predicted measurement value range corresponding to each channel quality parameter measurement value, and according to each channel quality parameter measurement value corresponding to Predict the recommended value of retransmission scheduling monitoring times corresponding to the range of measured values, respectively determine the suggested value of retransmission scheduling monitoring times corresponding to each channel quality parameter measurement value, and the terminal selects from all the currently obtained suggested values ​​of retransmission scheduling monitoring times The suggested value of the retransmission scheduling monitoring times with the largest value is used as the retransmission scheduling monitoring times.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for determining the number of monitoring times for retransmission scheduling. Background technique [0002] The Long Term Evolution (LTE) communication system has a flexible data scheduling and transmission mechanism. When a terminal needs to perform uplink data transmission, it needs to dynamically allocate and authorize uplink data transmission resources for it through the base station. [0003] Specifically, see figure 1 and figure 2 As shown, in the case that the terminal does not obtain the resource authorization for uplink data transmission, the process for the terminal to initiate uplink data transmission includes: [0004] Step 200: The terminal sends an uplink scheduling request (Schedule Request, SR), requesting the base station to allocate uplink data transmission resources, such as figure 1 Neutral frame 2. [0005] Step 210: After receiv...
