Description

Uplink signal sending method and device

Technical Field

The present invention relates to the field of mobile communications, and in particular, to an uplink signal sending method and apparatus.

Background

Uplink Physical channels of a Long Term Evolution (LTE) system include a Physical Random Access Channel (PRACH), a Physical Uplink Shared Channel (PUSCH), and a Physical Uplink Control Channel (PUCCH). The uplink of LTE employs a single carrier Orthogonal Frequency Division Multiplexing (OFDM) technique, and reference signals and data are multiplexed together by Time Division Multiplexing (TDM). The uplink Reference Signal includes a Demodulation Reference Signal (DM-RS) and a Sounding Reference Signal (SRS).

Because the uplink of LTE adopts a Single Carrier-Frequency division multiple Access (SC-FDMA) technology, and uplink signals of different User Equipments (UEs) in a cell are orthogonal to each other, the uplink power control is mainly used for compensating for Path Loss (PL) and shadowing of a channel and for suppressing inter-cell interference. The uplink power control can control the transmission power of the channels such as the PUSCH/PUCCH and the SRS. In the power control scheme of the existing Rel 10 LTE protocol (36.213Evolved Universal Radio Access (E-UTRA); Physical layer loss), the path loss value for compensating the uplink loss is obtained by measuring the downlink loss by the UE. The UE calculates the difference between the received pilot signal power and the pilot transmitting power indicated to the UE by the base station through the signaling to obtain a downlink path loss value, and uses the calculated path loss value as the path loss compensation of the uplink power control.

In a system using a single antenna or a traditional multi-antenna, because the transmitting end of the downlink of the UE and the receiving end of the uplink are in the same cell, the downlink path loss calculated according to the method can accurately reflect the uplink path loss, so that the reasonable estimation of the transmitting power of the uplink signal is realized, and the inter-cell interference of edge users is suppressed. However, in a distributed multi-antenna system or an uplink coordinated multi-point transmission (UL CoMP) system, since a transmitting node and a receiving node of an uplink and downlink signal at a UE end may be inconsistent, when the transmitting node and the receiving node of the uplink and downlink signal at the UE end are inconsistent, a difference between a PL value estimated according to a reference signal transmitted by the downlink transmitting node and an actual PL value between the uplink receiving node and the UE is large, and a PL value estimated by a downlink is used to estimate a transmitting power of a UE-side signal at an uplink, which may cause inaccurate estimation of a UE-end signal transmitting power, affect reception of the uplink signal at the UE and bring interference to users of adjacent cells.

Detailed Description

In a multiple Timing Advance (TA) scenario, because independent Timing advances are adopted between aggregated carriers, different carriers are partially overlapped in the same subframe, subframes of different carriers are not strictly aligned in time, and different from a carrier aggregation scenario in the same TA in the existing standard, path loss experienced by signals of different serving cells in the same subframe may have a large difference, so that a measurement mode for re-determining uplink path loss is required for the new scenario.

When the downlink serving Cell corresponding to the uplink serving Cell is of a new carrier type, since there is no Cell-specific Reference Signal (CRS), it is necessary to consider measuring the downlink path loss according to the Cell State Information Reference Signal (CSI-RS) and estimating the uplink path loss.

The CSI-RS introduced in the CoMP scene is considered, and the CSI-RS is also introduced in the scene with new carriers, so that an uplink path loss estimation mode based on the CSI-RS can be considered for uplink power control. Meanwhile, considering that the uplink path loss is not suitable to be calculated by using the reference signal of the same downlink serving cell under the multi-TA scene, the path loss measurement method needs to be distinguished according to the application scene, so as to ensure that the UE can obtain accurate uplink path loss estimation under different scenes, enhance the capacity of open-loop power control, and achieve the purpose of accurately controlling the uplink channel power.
