Embodiment Construction

[0091] In the embodiment of the present invention, two characteristics of the multi-period persistent scheduling include: there are multiple persistent scheduling periods; the specific value of the persistent scheduling period corresponds to the subframe transition point and the subframe where the initial transmission occurs.

[0092] The uplink and downlink subframe switching point period and switching point configuration of LTE TDD are determined in the system broadcast, that is, they are determined before the allocation of persistent scheduling resources, and will not change during the persistent scheduling process. Under some subframe transition point configurations, two subframes with RTT=10ms and 15ms may appear, and under some transition point configurations, there are only subframes with RTT=10ms. Therefore, in the embodiment of the present invention, only the correspondence between the subframe number and the persistent scheduling period needs to be considered in the a...

Abstract

The invention discloses an allocating method, a system and a device for continuous scheduling resources to realize allocation of multi-cycle continuous scheduling resources. The allocating method comprises the following steps: a network side allocates the continuous scheduling resources for a user terminal and sends the initial time and the cycle of the continuous scheduling resources to the userterminal; and the user terminal obtains the continuous scheduling resources allocated by the network side through the initial time and the cycle of the continuous scheduling resources.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, system and device for allocating persistent scheduling resources. Background technique [0002] In a wireless communication system, it is necessary to rationally allocate wireless resources (including time, frequency, code channel and other resources) to different users to complete the transmission of various services. When the characteristics of a certain service are known, such as data volume, data arrival time, etc., the data of this service can be sent in the way of persistent scheduling or semi-persistent scheduling to reduce the overhead of scheduling signaling. [0003] Semi-persistent scheduling means that the base station allocates fixed resources to one or several data packets of a certain service. It is sent in the form of dynamic scheduling, and resource allocation needs to be performed through scheduling signaling. [0004] Persistent...
