Embodiment Construction

[0030] combine first Figure 2A , an embodiment of a TFI allocation method of the present invention will be described. Such as Figure 2A shown, including:

[0031] Step S201A: assign non-zero TFI to each uplink TBF that uses PAN feedback of the terminal, the terminal is a terminal that supports SSN-based PAN, and the terminal is multiplexed with other terminals on the same channel.

[0032] In practical applications, the network side can receive TBFs sent by multiple terminals, and each terminal can also send multiple TBFs. Before the terminal sends the TBF to the network side, the network side needs to allocate a TFI for the TBF, where one TFI can be allocated to each TBF of each terminal, and each TFI is different from each other. For a terminal supporting the SSN-based PAN that is multiplexed on the same channel with other terminals, the TFI allocated to each TBF by the network side is not zero. In addition, other terminals multiplexed on the same channel as the termin...

Abstract

The invention provides a TFI allocation method, which comprises the following steps: allocating non-zero TFI to each uplink TBF using PAN feedback of a terminal, wherein the terminal supports SSN-based PAN and is multiplexed in the same channel together with other terminals; and providing the non-zero TFI to the terminal. The invention also provides a TFI allocation device, a PAN feedback method, a PAN feedback device, a feedback information differentiation method and a feedback information differentiation device. In the invention, TFI allocated to each uplink TBF using PAN feedback by the network side is not zero, so that the terminal supporting the SSN-based PAN does not succeed in checking the feedback information with time-based PAN, thereby obviating wrong feedback information obtained by the successful checking, and ensuring that the terminals multiplexed in the same channel can acquire the accurate feedback information.

Description

technical field [0001] The present invention relates to wireless communication technology, and in particular to short acknowledgment / negative acknowledgment (PAN, PiggybackedAcknowledged / Non-Acknowledged) feedback technology. Background technique [0002] In Global System for Mobile Communications (GSM, Global System for Mobile Communications), General Packet Radio Service (GPRS, General Packet Radio Service) system, Enhanced GPRS (EGPRS, Enhanced GPRS) system, a Time Division Multiple Access (TDMA, Time Division Multiple Access) ) frame consists of 8 time slots, generally 5ms. The smallest scheduling unit for data transmission at the physical layer is a wireless block (Block). Each Block consists of 4 time slots and is located in 4 consecutive TDMA frames. Therefore, the transmission time interval TTI of each Block is 20ms. The Block here is also called BTTI Block. At a high level above the physical layer, each logical link control (LLC, Logic Link Control) frame consists...
