Embodiment 1
[0105] This embodiment is described from the implementation flow of processing a new service.
[0106] Figure 5 It is a schematic flow diagram for implementing a method for sending uplink physical channel data including new services, as shown in the figure, which may include the following steps:
[0107] Step 501, start the process;
[0108] Step 502, judging whether a new service is activated, if yes, proceed to step 503, otherwise proceed to step 504;
[0109] In this step, it is detected whether there is a new service activated at present, and an initial priority is assigned to the uplink physical channel used by the new service; at the same time, the physical layer establishes a parameter Ni for the physical channel, and sets an initial value.
[0110] Step 503, update the LP (logical channel priority) of each channel, and the physical layer configures the number of times Ni to abandon sending for the new channel configuration introduced by the new service;

Embodiment 2
[0130] In this embodiment, the implementation of the method for sending uplink physical channel data will be described in combination with the scheduling program in the sixth point above.
[0131] Image 6 It is a schematic flow diagram for implementing a method for sending uplink physical channel data including a scheduler, as shown in the figure, which may include the following steps:
[0132] Step 601, the UE performs priority queuing for the uplink physical channels sent simultaneously in this time slot;
[0133] Step 602, calculate whether the queue length is greater than 2, otherwise proceed to step 603, and if greater than 2, proceed to step 604;
[0134] Step 603, sending the data on all physical channels in the queue, and the detection process of this time slot ends;
[0135] Step 604, calculating the priority of each channel in the queue;
[0136] Step 605, sending the data on the two physical channels with the highest priority in the queue;
[0137] Step 606, ju...

Abstract
The invention discloses a sending method and equipment of physical uplink channel data. The method comprises: determining the physical uplink channel number which needs to simultaneously send data for the user equipment in the same time slot; when determining the physical uplink channel number is determined to be larger than a threshold value, determining the priority of each physical uplink channel according to physical uplink channel performance, wherein the threshold value is the maximum value of the number of the physical uplink channel which permits to simultaneously send data; and according to the priority, sending the data on the physical uplink channel of which the number is same with the threshold value. The invention can cause the terminal to satisfy the rule of the 3GPP physical layer protocol to ensure that the number of the physical uplink channel which is simultaneously sent does not exceed the threshold value, simultaneously limits peak-to-mean ratio, lowers terminal realization complexity and lowers terminal cost.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a method and equipment for sending uplink physical channel data. Background technique [0002] HSDPA (High-Speed downlink packet access, high-speed downlink packet access) technology is an enhanced solution proposed by 3GPP Release5, which is also applicable to WCDMA (Wide-band Code Division Multiple Access, widebandcode division multiple accesssystem) and TD- SCDMA (Time Division Synchronized Code Division Multiple Access, time division synchronous CDMAsystem), the main goal of HSDPA is to provide high-speed transmission support for packet data services, the data transmission rate is very high, and to obtain lower time delay and higher systemthroughput Capacity and stronger QoS (Quality ofService, service quality) guarantee. LCR (Low Chip Rate, low code rate) TDD (Time division duplex, time division duplex) HSDPA introduces the downlink HS-DSCH (High Speed Downlink...
