example 1

[0201] This example proposes a semi-persistent scheduling transmission enhancement method. In this method, the base station uses high-level signaling to configure the transmission time window of semi-persistent scheduling transmission. After the physical layer downlink control information is activated, the user equipment can use the available transmission time window on the basis of ensuring that the dynamic scheduling is greater than the semi-persistent scheduling priority. Send or receive semi-persistent scheduling data on the transmission unit. This solution can shorten the transmission delay of semi-persistent scheduling data and increase the flexibility of semi-persistent scheduling.

[0202] Specifically, in this example, according to the transmission time window configured by the base station through high-level signaling, and on the basis of ensuring that dynamic scheduling is superior to semi-persistent scheduling, the user equipment can use the transmission unit of th...

example 2

[0210] This example provides a data transmission method with enhanced semi-persistent scheduling, which will be described from the base station side and UE side respectively below.

[0211] base station side

[0212] For the design of high-level configuration messages, the base station configures transmission time windows for users through high-level signaling configuration. Specifically, the configuration information and corresponding configuration methods include:

[0213] The window period of the transmission time window:

[0214] The design of the transmission time window is to ensure the timeliness and accuracy of the semi-persistent scheduling data packet transmission within each transmission interval, so the transmission time window should be configured to occur periodically, and its period and semi-persistent scheduling The transmission cycle remains the same.

example 1

[0215] Example 1: One of the above periodic transmission time windows as Figure 4 As shown, the window period T1 of the transmission time window is equal to the scheduling period T2 of the semi-persistent scheduling.

[0216] The time domain location of the transmission time window:

[0217] After the window period of the transmission time window is determined, its time domain position within each transmission period needs to be further determined, and its indication method can be specifically represented by the following three options:

[0218] Option 1: the start time domain position and the end time domain position of the transmission time window;

[0219] Option 2: the start time domain position and window length of the transmission time window;

[0220] Option 3: The end time domain position and window length of the transmission time window.

[0221] Option 4: The start position and end position of the transmission time window may be indicated by a relative position p...

Abstract

The embodiment of the invention discloses a semi-persistent scheduling data transmission method, a communication device and a storage medium. The data transmission method is applied to a communication device (UE), and includes: obtaining a configured transmission time window of semi-persistent scheduling, wherein the transmission time window includes: at least two transmission units; according to the obtained physical control channel Control information, one or more transmission units selected within the transmission time window perform semi-persistent scheduling data transmission.

Description

technical field [0001] The present invention relates to a synchronization technology in the field of wireless communication, in particular to a semi-persistent scheduling data transmission method, a communication device (User Equipment, UE) and a storage medium. Background technique [0002] In order to save control signaling overhead, in addition to dynamic scheduling, Long Term Evolution (LTE) and LTE-A systems also provide a Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS) method, which allows the base station SPS configuration is performed on user equipment, and the downlink control information of the physical layer is activated to achieve the purpose of periodically allocating radio resources to specific user equipment. It can be seen that semi-persistent scheduling has the characteristics of one-time scheduling and multiple transmissions. In this way, multiple transmission instructions are implemented with one scheduling, and compared with each transmission...
