Problems solved by technology

[0005] In the current LTE system, it has been determined that the conventional C-RNTI is sent to the UE by the base station through medium access control (MAC) layer control signaling during the random access process, and the method of sending the persistently scheduled C-RNTI has not yet been determined , a possible method is to notify the UE of the persistent scheduling C-RNTI adopted by radio resource control (RRC) signaling. This method needs to add corresponding fields in the RRC signaling, and because To assign a persistent scheduling C-RNTI to the UE, it is necessary to add corresponding indication bits to indicate whether the persistent scheduling C-RNTI exists, which will increase the overhead and complexity of RRC signaling

Embodiment Construction

[0019] The embodiment of the present invention proposes a method for sending persistent scheduling C-RNTI. The method adopts MAC layer control signaling to carry persistent scheduling C-RNTI, and the base station sends the MAC layer control signaling to UE, thereby implementing persistent scheduling C-RNTI. Sending of RNTI.

[0020] Firstly, it is necessary to introduce the structure of the MAC layer control signaling in the prior art. Such as figure 1 as shown, figure 1 It is a schematic structural diagram of MAC layer control signaling in the prior art.

[0021] The MAC layer control signaling includes a MAC subheader field (MAC Subheader) with a length of 1 byte and a MAC control element. figure 1 Among them, "R" is a reserved bit; "E" is an indication bit, which is used to indicate whether there are other MAC sub-header fields; the length of LCID is 5 bits, which is used to indicate the type of the subsequent MAC control unit or the logical channel logo.

Abstract

The invention provides a method and a base station for transmitting sustainable dispatching cell radio network temporary identity (C-RNTI). The method comprises the following steps that: the base station constructs a media access control (MAC) layer control signaling which bears the sustainable dispatching C-RNTI, wherein the MAC layer control signaling comprises an MAC sub-head field and an MAC control unit; and the base station transmits the MAC layer control signaling bearing the sustainable dispatching C-RNTI to user equipment (UE). The method and the base station can transmit the sustainable dispatching C-RNTI to the UE through the MAC layer control signaling, reduce complexity of the RRC signaling, and maintain accordant processing process.

Description

technical field [0001] The present invention relates to the technical field of long-term evolution (LTE), in particular to a method and a base station for sending a cell radio network temporary identifier (C-RNTI, Cell Radio Network Temporary Identifier) ​​for continuous scheduling. Background technique [0002] At present, a semi-persistent scheduling mechanism is introduced in the LTE system for specific services, such as VoIP services. The working mode of the semi-persistent scheduling mechanism is: adopt persistent scheduling for the initial transmission of specific service (such as VoIP service) data packets, and adopt dynamic scheduling for the retransmission of specific service data packets and the transmission of other data packets. [0003] Persistent scheduling means that the base station allocates fixed resources to the data packets of a certain service of the user equipment (UE) and specifies a fixed transmission format. Before the persistent scheduling starts, t...
