Problems solved by technology

It can be seen that dynamic scheduling and semi-persistent scheduling have their own advantages and disadvantages. Dynamic scheduling can schedule higher modulation and coding levels, but the PDCCH resource overhead is large. Semi-persistent scheduling has the smallest PDCCH resource overhead, but the highest MCS level for scheduling is 15.

Example Embodiment

[0044] Example one

[0045] As shown in Figure 2(a), the present invention relates to a method for dynamic delay scheduling of voice data, including:

[0046] S1: Determine whether the semi-persistent scheduling mode is turned on and whether the UE supports the semi-persistent scheduling mode; if yes, perform step S2 in sequence; otherwise, skip to step S3;

[0047] S2: Scheduling in a semi-continuous scheduling mode;

[0048] S3: Judge whether the dynamic delay scheduling mode is enabled, if yes, execute step S4 in sequence; otherwise, jump to step S5;

[0049] S4: Bundle two consecutive voice data packets for scheduling in a dynamic delay mode;

[0050] S5: Perform scheduling in a dynamic scheduling mode.

[0051] In this embodiment, only when the semi-persistent scheduling mode is turned on and the UE supports the semi-persistent scheduling mode at the same time, the semi-persistent scheduling mode is used for scheduling; otherwise, the dynamic delayed scheduling mode is used; if the d...

Example Embodiment

[0067] Example two

[0068] The present invention also provides a base station, such as image 3 Shown, including:

[0069] Judgment module to determine whether the semi-persistent scheduling mode is enabled and whether the UE supports the semi-persistent scheduling mode;

[0070] The semi-persistent scheduling module is used to perform scheduling in the semi-persistent scheduling mode when the semi-persistent scheduling mode is enabled and the UE supports the semi-persistent scheduling mode;

[0071] The dynamic delay scheduling module is used to judge whether the dynamic delay scheduling mode is enabled when the semi-persistent scheduling mode is not enabled, if so, bind two consecutive voice data packets in a dynamic delay scheduling mode for scheduling; otherwise, perform scheduling in a dynamic scheduling mode .

[0072] In this embodiment, only when the semi-persistent scheduling mode is turned on and the UE supports the semi-persistent scheduling mode at the same time, the semi...

Abstract

The invention relates to a voice data dynamic delay scheduling method and a base station. The dynamic delay scheduling method comprises the steps of judging whether a semi-persistent scheduling mode is opened or not and whether UE (user equipment) supports the semi-persistent scheduling mode or not; carrying out scheduling in the semi-persistent scheduling mode if the semi-persistent scheduling mode is opened and the UE supports the semi-persistent scheduling mode; judging whether a dynamic delay scheduling mode is opened or not if the semi-persistent scheduling mode is not opened or the UE does not support the semi-persistent scheduling mode, if yes, binding two continuous voice data packets to carry out scheduling in the dynamic delay scheduling mode; and if no, carrying out scheduling in a dynamic scheduling mode. Through adopting the dynamic delay scheduling method and the base station provided by the invention, half of the overhead of PDCCH (physical downlink control channel) resources is reduced. Meanwhile, a high modulation and coding level is kept, and the flexibility of voice service scheduling is improved, thereby being conducive to reasonable distribution of channel resources, and improving the user capacity of the base station.

Description

technical field [0001] The invention relates to a voice data dynamic delay scheduling method and a base station, belonging to the technical field of communication. Background technique [0002] Long Term Evolution (LTE for short) is an all-IP-based wireless communication technology. With its high-speed uplink and downlink data transmission rates, flexible bandwidth configuration, and simplified network architecture, it has become the most powerful competitor of the 4G standard. . The resources of the LTE radio interface are shared, and signaling and data simultaneously compete for these shared resources for transmission. At present, radio resource scheduling schemes that may be used for Voice over LTE (VoLTE, VoLTE for short) services include dynamic scheduling, semi-persistent scheduling, and group scheduling. Dynamic scheduling is a general scheduling method. For each physical resource block (Physical Source Block, abbreviated as PRB), a basic unit of wireless resource s...
