Problems solved by technology

However, in the existing protocol, the network allocates the right to use the uplink channel to the terminal user through the uplink state flag (USF, Uplink State Flag) carried by the downlink channel. , for users using new terminals with RTTI functions, the remaining 10ms cannot be used, resulting in a waste of network resources
[0008] Moreover, in the existing protocol, USF is mapped to 4 consecutive time slots of a downlink PDCH, and after the introduction of RTTI, the structure of the Block is no longer like In the existing protocol, it appears on 4 consecutive time slots of a PDCH, but appears on multiple PDCHs. However, when a terminal without RTTI function receives the downlink USF, it still receives 4 consecutive time slots of a downlink PDCH. In this way, the USF value cannot be received correctly, which affects the compatibility of the evolved network with existing terminals

Embodiment 1

[0030] 1) The network maps the uplink status identifier to each time slot of the corresponding downlink channel; the uplink status identifier includes a channel assignment identifier and a time slot assignment identifier, and the channel assignment identifier indicates that the user is allowed to occupy the corresponding uplink channel within a specified period of time. For a user, the time slot allocation identifier indicates that the user is allowed to occupy the time slot of the uplink channel;

[0031]In fact, the channel allocation identifier in the present invention plays the role of the uplink status identifier in the existing protocol. For the sake of brevity, the present invention and the existing uplink status identifier are respectively referred to as the USF of the present invention and the existing USF in the following, The channel allocation identifier is called CHF, and the time slot allocation identifier is called BF.

[0032] First, the control of CHF on chann...

Embodiment 2

[0040] Obviously, in this embodiment, the CHF value in one direction of the same channel is unique.

[0041] Embodiment 3. A method for allocating uplink packet data channels. Step 1) of the method in this embodiment is the same as in Embodiment 1, except that in step 2) when the USF of the present invention is put into the downlink channel, the following method is adopted: each Each USF of the present invention is mapped to four consecutive time slots of the corresponding downlink channel.

Embodiment 3

[0042] In the existing protocol, the USF is used as a part of the Media Access Control (MAC, Media Access Control) / Radio Link Control (RLC, Radio Link Control) data header (Header), and the other parts of the header and the data part ( Data) are mapped to the downlink channel together, such as Figure 4 as shown, Figure 4 One RLC block containing USF is mapped to four time slots (5ms) of one TTI (20ms) of the PDCHi channel. The existing USF is usually the first 3 bits of the RLC / MAC header, which are 12 or 36 bits after being encoded by GMSK or 8PSK alone. The encoded USF and other content are placed in a downlink PDCH according to the mapping rules stipulated in the protocol. In the 4 consecutive time slots, because the USF data is encoded separately, the user can decode the USF after completely receiving the 4 time slots, and does not need to care about the content of other parts.

[0043] However, after using RTTI, the data block is no longer 4 consecutive time slots on ...

Abstract

A method for distributing uplink packet data channel includes making expansion on USF controlling distribution of uplink channel and furthermore adding time slot distribution identification for distributing time slot at specified time interval on USF and utilizing added time slot identification to distribute different time slot in the same time interval of the same PDCH different user for service.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an uplink packet data channel (PDCH, Packet Data CHannel) allocation method and a data transmission method. Background technique [0002] With the continuous increase in bandwidth requirements of new mobile services, the high-speed wireless data technology with higher spectrum utilization has increasingly become the focus of attention in the mobile field. At present, the packet data service of the mobile communication network is mainly carried by a general packet radio service (GPRS, General Packet Radio Service) network. The GPRS network is the evolution and extension of the Global System for Mobile communications (GSM, Global System for Mobile communications) network, mainly adding packet services. GPRS still uses the same Gaussian Minimum Shift Keying (GMSK, Gaussian Minimum Shift Keying) modulation method as GSM. Due to the limitation of the signal modulation ...
