Problems solved by technology

[0004] In hybrid multi-links, the service data transmission error of UPA link set is relatively high, and power increase is required. However, the combination result obtained by UE according to the protocol will have a high probability of power reduction. At this time, the power increase of UPA link set cannot be satisfied. requirements, thus leading to an increase in the bit error rate of the uplink transmission of the UPA link set

Embodiment 1

[0025] see figure 2 , an embodiment of the present invention provides a transmission power control method, the method comprising:

[0026] Step 101: Obtain the current environment information of the multi-link, the current environment information at least includes the TPC soft value of each link set in the multi-link, and / or, the first data transmission of the number of UPA link sets in the multi-link bit error rate;

[0027] Among them, according to the specific value of the TPC soft value of the link set, it can be known whether the link set requires a power increase or a power reduction. The TPC soft value of the link set is a random number 0 and 1. 0 indicates that the link set requires power reduction. 1 indicates that the link set requires power up.

[0028] Step 102: When the multi-link is a hybrid link set of an R99 link set and a single UPA link set, determine whether the current environment information belongs to a problem scenario. The problem scenario specifical...

Embodiment 2

[0034] see image 3 , an embodiment of the present invention provides a transmission power control method, the method comprising:

[0035] Step 201: Obtain current environment information of multiple links;

[0036] Wherein, the execution subject of this step is UE. In the uplink inner loop power control, the Node B is the controller, and the UE is the executor. Under multi-link, the UE uses the TPC combination function γ to combine the TPC soft values ​​given by the Node B through the downlink. , and adjust the transmit power of the uplink according to the combination result.

[0037] In practical applications, there are situations where a UE is connected to multiple links at the same time. Although the UE sends a copy of uplink data to all Node Bs in the uplink direction at the same time, the wireless propagation environment between the UE and different Node Bs is different. , the UE will simultaneously receive downlink TPC commands from different Node Bs. At this time, ...

Embodiment 3

[0069] see Figure 4 , the embodiment of the present invention provides a transmission power control device, the device includes an acquisition module 301, a judgment module 302, an adjustment module 303 and a control module 304:

Abstract

The invention discloses a transmission power control method and a transmission power control device and belongs to the field of communication. The method comprises the following steps: obtaining current environmental information of a multilink; judging whether the current environmental information belongs to a problem scene or not, adjusting TPC (Transmit Power Control) merging functions when the current environment information belongs to the problem scene, merging TPC soft values of link sets in the multilink according to the adjusted TPC merging functions to obtain merged results, so that the merged results satisfy the requirements of the up power of a single UPA (Uplink Packet Access) link set; and controlling the uplink power according to the merged results. The transmission power control method and the transmission power control device have the benefit that the merged results of the multilink are adjusted to tend to the requirements of a TPC soft value of the single UPA link set, so that a TPC command of the up power probably occur, the transmitting power is improved, the transmitting performance is improved, the maximum transmission time achieved by business data is reduced, and the situation of wireless data transmission link interruption occurs.

Description

technical field [0001] The present invention relates to the communication field, in particular to a transmission power control method and device. Background technique [0002] In the existing 3GPP-UMTS (Universal Mobile Telecommunications System, third-generation mobile communication system) protocol, there are currently three types of uplink soft handover activation set combinations, namely pure R99 link set, pure UPA link set and hybrid link set , the multi-link is a hybrid link of an R99 link set and a UPA (Uplink Packet Access) link set, where the R99 link set carries signaling data, and the UPA link set carries service data. Each link set of the multi-link has TPC (Transmit Power Control, transmit power control) soft value. The multi-link uplink power control technology means that a UE (User Equipment, user equipment) receives uplink power control information sent by a NodeB (Node Base, base station), and controls the uplink transmit power of the UE according to the up...
