Problems solved by technology

[0008] However, when the base station configures multiple sets of uplink power control parameters for the terminal, the PHR reporting mechanism in the prior art does not address the subframes using different uplink power control parameters and the transmission conditions of PUSCH and PUCCH on the corresponding subframes. The method of reporting the corresponding PHR, which will cause the problem of inaccurate PHR report and large signaling overhead of PHR report

Embodiment 1

[0093] The present invention provides terminal-side operations in the method for reporting PHR, including: the terminal reports Type1PHR and Type2PHR corresponding to uplink subframe group one, and Type1PHR corresponding to uplink subframe group two.

[0094] Specifically, the operation on the terminal side in the above method of reporting PHR may be as follows figure 1 Shown include:

[0095] Step 101: The terminal judges whether the extended PHR and PUCCH-PUSCH simultaneous transmission parameters configured by the corresponding base station are received, and if so, executes step 102; otherwise, performs follow-up operations according to the prior art, and ends the processing flow.

[0096] Step 102: The terminal reports the Type1PHR and Type2PHR corresponding to the first uplink subframe group, and the Type1PHR corresponding to the second uplink subframe group.

[0097] Preferably, the above step 102 may also be: the terminal reports Type1PHR and Type2PHR corresponding to ...

Embodiment 2

[0115] The operation on the base station side in the PHR reporting method provided by the present invention includes: the base station receives reports of Type1PHR and Type2PHR corresponding to uplink subframe group 1 and Type1PHR corresponding to uplink subframe group 2.

[0116] Specifically, the operation method on the base station side in the above PHR reporting method, such as figure 2 shown, including:

[0117] Step 201: The base station sends configuration parameters for simultaneous transmission of extended PHR and PUCCH-PUSCH.

[0118] Step 202: The base station receives reports of Type1PHR and Type2PHR corresponding to uplink subframe group 1 and Type1PHR corresponding to uplink subframe group 2.

[0119] Preferably, before the step 202, the method further includes: the base station determines the information of the subframes included in the uplink subframe group 1 and the uplink subframe group 2 respectively, and sends the information through signaling;

[0120] ...

Embodiment 3

[0137] Such as image 3 As shown, assuming that the base station adopts TDD uplink and downlink configuration 0 in Table 1, the base station determines that subframes 2 and 7 belong to uplink subframe group 1, and subframes 3, 4, 8, and 9 belong to uplink subframe group 2.

[0138] Here, the process for the base station to determine the subframes included in the uplink subframe group 1 and the uplink subframe group 2 includes:

[0139] The base station obtains the TDD uplink and downlink configuration information of other base stations whose distance is less than the preset value, and judges that subframes 2 and 7 in the TDD uplink and downlink configuration of these base stations are all uplink transmission subframes, and subframes 3, 4, 8, 9, there is one or several base stations that configure it as a downlink transmission subframe, then the base station determines that 2 and 7 belong to the uplink subframe group 1, and subframes 3, 4, 8, and 9 belong to the uplink subframe...

Abstract

The present invention discloses a PHR reporting method, device and system, said method comprising: a terminal reporting a Type1 PHR and a Type2 PHR, corresponding to a first uplink subframe group, and a Type1 PHR corresponding to a second uplink subframe group.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method, device and system for reporting PHR. Background technique [0002] The uplink and downlink configuration methods of the Long Term Evolution (LTE, Long Term Evolution) system Time Division Duplex (TDD, Time DivisionDuplex) mode are shown in Table 1, where D indicates that the subframe is used for downlink transmission, and U indicates that the subframe is used for uplink transmission , S represents a special subframe and includes three special time slots, namely, downlink pilot time slot (DwPTS, Downlink PilotTime Slot), guard interval (GP, Guard Period) and uplink pilot time slot (UpPTS, Uplink Pilot TimeSlot). [0003] [0004] Table 1 [0005] It can be seen from Table 1 that when different cells adopt different uplink and downlink configurations, the terminal will only receive uplink interference caused by the uplink transmission of terminals in other cells wh...
