Problems solved by technology

[0017] However, in a CA-based dual connectivity system, since multiple PUCCHs carrying UCI and multiple PUSCHs carrying UCI are simultaneously transmitted, the above UL power allocation mechanism and the power adjustment only for PUSCHs carrying data are inappropriate

Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] figure 2 It shows a mobile device 1 for allocating uplink power according to one aspect of the present invention, wherein the mobile device 1 is simultaneously connected to at least two network access devices through the carrier components of each network access device, wherein the mobile device 1 includes priority Level determination means 11 and power distribution means 12. Specifically, the priority determining means 11 determines the power allocation priority information of each uplink physical channel of the multiple target connections corresponding to the mobile device, where the target connection corresponds to the One: the power allocation unit 12 allocates transmission power for each uplink physical channel of the plurality of target connections according to the power allocation priority information and combined with the maximum output power...

Abstract

An object of the invention is to provide a method and apparatus for assigning uplink power. Specifically, determining power assignment priority information of every uplink physical channel of multiple target connections corresponding to mobile device; assigning transmission power for every uplink physical channel of multiple target connections based on the power assignment priority information along with the maximum output power of mobile device. Compared with the prior art, by determining power assignment priority information of every uplink physical channel of multiple target connections corresponding to a mobile device, so as to assign transmission power for every uplink physical channel of multiple target connections based on the power assignment priority information along with the maximum output power of mobile device, this invention realizes an uplink power assigning method, so that the uplink power assignment method according to the invention may be applied to the situation of simultaneous transmission of multiple PUCCHs carrying UCI, simultaneous transmission of multiple PUSCHs carrying UCI, as well as simultaneous transmission of PUCCH carrying UCI and PUSCH carrying UCI in the same subframe, so that supporting the carrier aggregation-based dual-connectivity.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a technology for allocating uplink power. Background technique [0002] In heterogeneous networks, the introduction of low-power network nodes faces many challenges, such as uplink (UL, up link) / downlink (DL, down link) power imbalance, mobility robustness, frequent switching, and thus The resulting signaling overload, and the low resource utilization between nodes due to non-ideal backhaul (non-ideal backhaul), which significantly limit network performance. [0003] In 3GPP RAN2, dual connectivity (dual-connectivity) is defined as an effective solution to the above problems. In dual connectivity, a user equipment (UE) is simultaneously connected to at least two network nodes, which may operate on the same or different frequencies. Dual connectivity is typically applicable to multiple base stations such as eNBs (evolved-NodeBs) connected to each other via a n...
