Embodiment Construction

[0027] Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0028] Certain terms are used throughout the specification and claims to refer to specific originals. Those skilled in the art can know that a manufacturer may refer to an original by different names. In this document the originals are not distinguished by name, but by function. In the following paragraphs as well as in the claims, the words "comprising" and "including" are used in open-ended expressions, and thus may be translated as "including but not limited to". Also, the word "coupled" refers to a direct or indirect electrical connection. Accordingly, if one device couples to another device, that connection may be through a direct electrical connection, through an indirect electrical connection, or through other devices and connections. The notations and their use in the disclosed embodiments are discussed below. However, ...

Abstract

Methods and apparatus are provided for contention-based UL resource reservation and power control for UL non-orthogonal multiple access. In one novel aspect, the UE selects a resource block from a resource pool, sends an uplink message based on the selected resource block requesting a resource reservation with or without a reservation resource request (RRR), and receives a response signal indicating the success of resource reservation. In one embodiment, the resource pool is related to one or more identifications comprising a cell ID, a UE ID, a subframe number, and a frame number, and whereinthe UE derives the resource pool based on the one or more identifications. In another novel aspect, the UE selects a power offset from a configured power offset pool and calculates a transmit power based on the path loss, a target power and the selected power offset.

Description

[0001] Cross References to Related Applications [0002] This application was submitted on August 12, 2016 in accordance with 35 U.S.C. §111(a), 35 U.S.C. §120 and §365(c), the application number is PCT / CN2016 / 094911, and the title is "UL Data Transmission (UL DATA TRANSMISSION), the subject matter of which is hereby incorporated by reference. technical field [0003] The present invention relates generally to wireless communications, and more particularly to indication and implementation of uplink (UL) transmissions by UEs. Background technique [0004] Machine-Type Communication (MTC) teaches an important way for operators and has great potential from an operator perspective. The cost reduction of the MTC UE / device is an important enabler for the realization of the Internet of Things (IOT) concept. Many MTC devices are aimed at low-end (low average cost per user, low data rate) applications that are sufficient to be handled by GSM, GPRS. Due to the low cost (LC) of the...
