Problems solved by technology

The coverage performance of waveform A is relatively good, but since the uplink subcarriers of the UE must be continuous, more restrictions are placed on scheduling; the coverage performance of waveform B is relatively poor, but resource allocation is flexible
[0003] The scheduling method of the prior art cannot be applied to NR because it does not involve a variety of uplink waveforms

Embodiment Construction

[0086] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0087] The technical solutions in the embodiments of the present invention can be applied to various wireless communication systems, such as Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) networks, Orthogonal FDMA (OFDMA) network, single-carrier FDMA (SC-FDMA) network, etc. The terms "network" and "system" are often used interchangeably. A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), CDMA2000, and so on. UTRA includes Wideband-CDMA (W-CDMA) and other CDMA variants. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network may implement a radio technology such as Global System for Mobile Communications (GSM). An OFDMA network may implement radio technologies such as Evolved UTRA (E-UTRA), Ultr...

Abstract

The embodiment of the invention discloses an uplink waveform indication method and related equipment, which can perform effective scheduling according to various uplink waveforms. The method in the embodiment of the present invention includes: the UE receives an indication message from the base station, and the indication message is used to indicate the target uplink waveform of the UE; when the target uplink waveform is different from the first uplink waveform used by the UE, the UE changes the uplink waveform from the first The uplink waveform changes to the target uplink waveform and triggers the PHR. Through the embodiments of the present invention, after the waveform of the UE is changed, the reporting of the PHR can be triggered, so that the base station can perform effective scheduling according to various uplink waveforms.

Description

technical field [0001] The present application relates to the communication field, in particular to an uplink waveform indication method and related equipment. Background technique [0002] In the new radio (new radio, NR) standard, uplink multi-waveform is introduced. The original uplink waveform (hereinafter referred to as "waveform A") in the long term evolution system (long termevolution, LTE) requires that the uplink subcarriers used by the user equipment (UE) in the same subframe must be continuous, and the uplink subcarriers introduced in NR The new uplink waveform (hereinafter referred to as "waveform B") does not have this requirement. The coverage performance of waveform A is relatively good, but since the uplink subcarriers of the UE are required to be continuous, more restrictions are placed on scheduling; the coverage performance of waveform B is relatively poor, but resource allocation is flexible. [0003] The scheduling method in the prior art cannot be app...
