Problems solved by technology

But the solution requires hundreds of repetitions, which is not efficient in terms of cell throughput or in terms of device power consumption
On the other hand, in wireless networks, some other applications, such as vehicle-to-vehicle communication, may require low latency

Embodiment Construction

[0041] Reference will now be made in detail to some embodiments of the invention, and the accompanying drawings illustrate examples of the invention.

[0042] figure 1 It is a schematic diagram of a wireless communication system according to an embodiment of the present invention. The wireless communication system 100 includes one or more wireless networks, and each wireless communication network has fixed infrastructure units, such as wireless communication base stations 102, 103, and 104, forming a wireless network distributed in a geographical area. A base station may also be called an access point, an access terminal, a base station, a node B (Node-B) or an evolved node B (eNode-B, eNB), or other words in the field. Each of the receiving wireless communication base stations 102, 103, and 104 serves a geographic area. Backhaul connections 113 , 114 and 115 connect to non-colocated wireless communication base stations, such as base stations 102 , 103 and 104 . These backha...

Abstract

Methods and apparatus are provided for narrowband UEs. In one novel aspect, frequency hopping is used. The UE stays on the first frequency band for consecutive number of subframes before hopping to another frequency band. In another embodiment, the first set of resource elements and the second set of resource elements are discontinued with a gap in the time domain. In another novel aspect, the UE obtains sub-band information and a resource index and generates a communication channel for data frame transmission and receiving. In one embodiment, the UE further acquires the sub-band set information through system information. In yet another embodiment, the resource index is acquired from DCI. In yet another novel aspect, resource blocks are selected for a PUCCH for a narrowband UE. The UE determines an operating sub-band information and selects one or more narrowband regions for the PUCCH.

Description

[0001] Cross References to Related Applications [0002] This application is based on 35 U.S.C. §111(a), and based on 35 U.S.C. §120 and §365(c), required to be submitted on July 11, 2014, the application number is PCT / CN2014 / 082096 titled "ENB and UE UL transmission and reception method (Method for eNB, UE Uplink transmission and reception)" is the priority of the international patent application, and the subject matter of the above application is hereby incorporated by reference. technical field [0003] The disclosure relates generally to wireless communications, and more specifically to uplink (UL) transmission and reception by various UEs. Background technique [0004] In recent years, wireless communication systems have more and more diversified requirements, and corresponding UEs may have different capabilities. As an example, 3GPP LTE Release 12 defines new UE types with single receive (RX), unicast channels limited to 1000-bit Transport Block Size (TBS), and can a...
