Abstract: A method of power headroom reporting in adaptive TDD systems is proposed. A UE obtains configuration information from a base station in an adaptive TDD system. Each radio frame comprises a plurality of subframes, which are configured into two or more subframe sets. The UE determines a power headroom reporting (PHR) triggering condition. The UE performs PHR for at least one of the configured two or more subframe sets upon satisfying the triggering condition. In one embodiment, the UE sends PH values for all subframe sets in the same PH reporting subframe. In another embodiment, the UE sends PH values for different subframe sets in different PHR reporting subframes.

Abstract: Methods and apparatus of resource allocation (RA) for low cost machine communication type (LC-MTC) user equipments (UEs) are provided. A UE obtains one or multiple sets of resources in a mobile communication network. Each set of resources belongs to a narrow sub-band in a wider channel bandwidth, wherein the narrow sub-band comprises a plurality of contiguous physical resource blocks (PRBs). The UE determines a first set of resources from the one or multiple sets of resources based on a physical layer control signaling and transmits or receives radio signals using the first set of resources within a predefined duration. In a coverage extension mode, the UE determines a second set of resources according to a hopping pattern, while the first and the second sets of resources are occupied for transmission at different radio subframes. The UE then transmits or receives radio signals using the second set of resources.

Abstract: A method of separate accumulation in closed-loop power control in adaptive TDD systems is proposed. A UE obtains configuration information from a base station in an adaptive TDD system. Each radio frame comprises a plurality of subframes, which are configured into two or more subframe sets. The UE receives a transmit power control (TPC) command in a downlink subframe. The UE determines a power control adjustment state for an uplink subframe i based on the TPC command. The power control adjustment state of subframe i is accumulated from a power control adjustment state of a previous uplink subframe j, where subframe i and subframe j belong to the same subframe set. In one embodiment, subframe j is the closest previous uplink subframe with respect to uplink subframe i.

Abstract: Aspects of the disclosure provide a method for physical broadcast channel (PBCH) processing at a base station (BS) in a wireless communication system. The method can include performing a channel coding process to generate encoded PBCH data at the BS. The encoded PBCH data is to be carried in a synchronization signal block (SS block) having an SS block index (SBI), and transmitted from a cell having a cell ID. The method can further include performing a second scrambling over the encoded PBCH data with a second scrambling code determined based on the cell ID and the SBI to generate second scrambled PBCH data.

Abstract: A method of DRX operation enhancement in adaptive TDD systems is proposed. A UE configures and enters DRX operation in an LTE/LTE-A mobile communication network. The UE obtains adaptive TDD configuration information from a base station. The adaptive TDD configuration information comprises an actual TDD configuration and a reference TDD configuration. The UE performs DRX timer counting and HARQ timer counting based on the reference TDD configuration. The UE also synchronizes DRX status with the base station. With the reference TDD configuration, it can avoid the potential misunderstanding between eNB and UE regarding DRX and HARQ RTT timing when TDD configuration changes.

Abstract: A method of DRX and HARQ operation enhancement in adaptive TDD systems is proposed. A UE establishes a radio resource control (RRC) connection with a base station in a mobile communication network. The UE obtains adaptive time division duplex (TDD) configuration information from the base station, wherein the adaptive TDD configuration information comprises an actual TDD configuration and/or a reference TDD configuration.

Abstract: A method of UE transmit power adjustment based on TPC command in adaptive TDD systems is proposed. A UE obtains TDD configuration information from a base station in an adaptive TDD system. The UE also obtains an HARQ reference configuration from the base station. The UE then receives a transmit power control (TPC) command in one or more previous subframes. The UE performs power adjustment in a subsequent subframe based on the TPC command. The location of the previous subframes is determined based on the HARQ reference configuration. In one embodiment, an UL HARQ reference configuration is applied for PUSCH power control. In another embodiment, a DL HARQ reference configuration is applied for PUCCH power control.
