摘要: Methods for reporting a transmission mode and a UE are provided. In a novel aspect, a method for reporting a transmission mode, comprising: receiving a random access resource configuration from a base station by UE in a communication network; selecting random access resources according to a transmission mode capability of the UE, transmitting a first message by using the selected random access resources; transmitting a third message according to a random access response RAR, wherein the third message contains information of the transmission mode supported by the UE. The method for reporting the transmission and the UE provided by the invention can reduce the peak-to-average power ration of the signals transmitted by the UE or provide the higher peak rate of the uplink transmission.

摘要: A method for scheduling an uplink control information (UCI) resource for user equipment includes: receiving downlink control information (DCI); determining the position of a UCI resource region corresponding to a physical downlink share channel (PDSCH) signal scheduled by the DCI according to a predefined rule, wherein the UCI resource region comprises a plurality of UCI resources in a time domain and/or a frequency domain; and transmitting an ACK/NACK signal corresponding to the PDSCH signal in the UCI resource region.

摘要: Methods and apparatus are provided for a UE to send channel status reports (CSR) to a network entity. In one novel aspect, the CSR is generated at the MAC layer. In one embodiment, the UE detects one or more triggering event, obtains a value of channel status from the PHY layer, generates the CSR based on the value obtained from the PHY layer and transmits the channel status report to an eNB. In another embodiment, the UE starts a timer and waits for a UL grant to transmit the CSR. If no UL grant is received before the timer expires, the UE triggers either a dedicated SR or a random access SR. In another novel aspect, the channel status report is generated in a NAS message and sent to a NAS entity through the NAS layer. In one embodiment, the tracking-area-update procedure is used for the CSR.

摘要: Methods for transmitting a waveform in the wireless communication networks are provided. A method for UE to transmit to an eNB an uplink channel carrying data or control information bits, comprising: receiving a downlink channel occupying a set of downlink resource elements, where each downlink resource element has a downlink subcarrier spacing in the frequency domain and a downlink symbol duration in the time domain; generating a SC-FDMA based uplink channel from the information bits, where the uplink channel occupies a set of uplink resource elements and each uplink resource element has a uplink subcarrier spacing in the frequency domain differing from the downlink subcarrier spacing, and a uplink symbol duration in the time domain differing from the downlink symbol duration; and transmitting the SC-FDMA based uplink channel. In one embodiment, the information bits are uplink data information bits. In another embodiment, the information bits are uplink control information bits.

摘要: 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.
