Embodiment 1

[0016] As mentioned above, at present, when the terminal cannot receive the message on the subframe where the base station may send a control message containing persistent allocation content (for example, the persistent allocation control message, Persistent Allocation A-MAP Information Element), it cannot determine that it is the base station. The message is not sent, or the terminal itself cannot successfully decode the message. For this reason, the embodiment of the present invention first provides a message sending method, which informs the terminal whether the base station sends the resource persistently by adding an indicator or indication information to the message. Assign control messages.

[0017] In the message sending method according to the embodiment of the present invention, the base station sends a first message to the terminal through a downlink channel in a time region (for example, one or more subframes), and carries a second message indication identifier in the ...

Embodiment 2

[0021] In this embodiment, a terminal-side processing procedure based on the first embodiment is provided. On the terminal side, the terminal that has obtained the persistent resource tries to receive non-user-specific control information on the subframe or frame corresponding to its persistent allocation period to determine whether the persistent resource allocation related to the terminal has changed.

[0022] Specifically, in this embodiment, after receiving the first message, the terminal will obtain the indication flag (Persistent A-MAP IE Existence Flag) carried in the first message, and perform subsequent operations according to the indication flag. Specifically, if the second message indication identifier indicates that the base station sends the second message within the time zone, but the terminal does not receive the second message within the time zone, the terminal feeds back error reception information to the base station; if the second message indicates the identifie...

example 1

[0025] Table 1 shows part of the content of non-user-specific control messages. Assuming that the terminal MS-A has obtained the persistent resource allocation and the persistent resource allocation control message receiving error feedback channel (MAP NACK Channel), after the terminal MS-A receives the non-user-specific control message sent by the base station, if the message The persistent resource allocation control message contained in the indicator indicates that the identifier is valid, that is, Persistent A-MAP IE Existence Flag=1, but the terminal MS-A does not successfully receive the resource persistent allocation control message in this subframe, the terminal MS-A passes The MAP NACK Channel feeds back information to the base station that it has not successfully received the persistent resource allocation control message. It should be noted that the indicator of the persistent resource allocation control message can also be implicitly included in the cyclic redundanc...

Abstract

The invention discloses a message sending method and a message feedback preprocessing method. In the message sending method, a base station sends a first message to a terminal in a period of time; an indicator of a second message is carried in the first message; the indicator of the second message is used to indicate whether the base station will send the second message in the period of time; the first message includes non-user-specific control information, user specific control information or downlink control information, and the second message includes resource persistent allocation Advanced-MAP information element hereinto. By the invention, the terminal can be made to learn whether the base station sends the control message containing resource persistent allocation Advanced-MAP information element, and then execute follow-up operation correctly.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a method for sending messages and a method for preprocessing message feedback. Background technique [0002] In the communication field, in order to effectively reduce the control overhead of the communication system and increase the throughput of the entire system, for periodic and relatively constant data packet size and modulation code speed (ModulationCode Speed, referred to as MCS) business, usually a persistent Persistent Allocation (PA) is used to manage resources. [0003] When the periodic service starts, the base station allocates fixed resources to the terminal, and sends a corresponding control message (for example, a persistent resource allocation control message) containing PA allocation content to the terminal. The message is sent only once at the beginning, and then the terminal Use the allocated fixed resources to receive or send data, and the PA allocation will no...
