Problems solved by technology

However, the above solutions also have considerable risks
As mentioned above, the PLCCH is a common channel, so it is impossible to perform beam forming (Beam Forming) on ​​it, which will result in considerable link budget loss; and, the PLCCH always needs to target all users supported by it transmit at the maximum transmission power required by the device, when there is a user equipment that is very close to the cell boundary and farthest from the node B, let this user equipment be UE1, and the PLCCH will transmit at the transmission power required for UE1 , the transmit power will probably occupy most of the link budget (Link Budget) of the Node B; therefore, from the perspective of transmit power resources of the physical channel, the solution is still uneconomical

Embodiment Construction

[0032] figure 2 , image 3 , Figure 4 and Figure 5 An example of the method of the present invention is shown.

[0033] When high-rate downlink packets are accessed in the 1.28Mcps time division duplex mode, if the transmission of downlink packet data of the user equipment is not accompanied by the transmission of downlink session service data at the same time, except for the In addition to the method of transmitting the high layer signaling radio bearer of the user equipment through the HS-DSCH, according to the method of the present invention, such as figure 2 As shown, the high-layer signaling radio bearer of the user equipment can also be transmitted through a downlink dedicated channel (DCH: Dedicated Channel), that is, the DCCH is mapped to the downlink DCH; the downlink DCH is a transmission channel or a coded composite transmission The channel is further mapped onto one or more downlink DPCHs, the downlink DPCHs are associated with the HS-DSCH, and the physical...

Abstract

The invention provides the down special physical channel allocating method when the time division duplex high speed down link packet access, the user apparatus with only the downlink packet data operation would multipex the one or the above one the down special physical channel, the said down special physical channel and the high speed down sharing channel connect, the power controlling order transferring the said user apparatus, the in-phase adjusting order and the high floor information sign are on the sharing body; the said down special physical channel allots periodically, in the one said allocating period, the said down special channel is allocated equally in the said user apparatus to transfer the power controlling order and the in-phase adjusting order of all the said user apparatus, or it can be occupied by the one user apparatus to transfer the high level ordering information of the user apparatus; in the wireless link inspecting time windows mounted by the system, the at last allocating period in which the said down special physical channel allots equally in the said user apparatus is existing.

Description

(1) Technical field [0001] The present invention relates to a wireless communication resource optimization method in a wireless mobile communication system, and more specifically relates to a time division duplex (TDD: Time Division Duplex) high-rate downlink packet access ( HSDPA: High Speed ​​Downlink Packet Access) downlink dedicated physical channel (DPCH: Dedicated Physical Channel) allocation method. (2) Background technology [0002] High-rate downlink packet access is a new feature of the third generation mobile communication system, which can be implemented in both Frequency Division Duplex (FDD: Frequency Division Duplex) mode and Time Division Duplex mode of the third generation mobile communication system. In the high-speed downlink packet access mode, a data transmission rate of up to 10Mb / s can be provided in the downlink to support business types that require instantaneous high data transmission rates in one direction of the downlink, such as web browsing (Int...
