METHODS FOR ENB, UE UPLINK TRANSMISSION AND RECEPTION
First Claim
1. A method, comprising:
- generating a communication channel by a user equipment (UE) in a wireless communication network, wherein the communication channel is mapped to a sequence of resource elements, each resource element is with a frequency sub-band of a system frequency bandwidth and a time domain subframe number;
selecting a first set of resource elements with a first frequency band for consecutive number N of subframes for the communication channel, wherein the first frequency band is a sub-band of the system bandwidth;
hopping to a second set of resource elements with a second frequency band every N consecutive number of subframes for the communication channel, wherein the second frequency band is a sub-band of the system bandwidth, and wherein the first and the second frequency band are different; and
sending or receiving information bits on the communication channel.

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.

16. A method, comprising:
-
determining an operating sub-band information by a user equipment (UE) in a wireless network, wherein the operating sub-band is smaller than a system bandwidth, and wherein the UE operates in the sub-band; selecting one or more narrowband regions for a physical uplink control channel (PUCCH) for the UE based on the determined operating sub-band information, wherein the one or more selected narrowband regions are at corresponding known locations of the operating sub-band; and sending control information to the wireless network on the PUCCH. - View Dependent Claims (17, 18, 19, 20, 21)
