Abstract: Methods and apparatus are provided for Msg3 collision resolutions. In one embodiment, the UE obtains a set of DMRS seeds and randomly selecting one to generate a DMRS sequence for the Msg3. The set of DMRS seeds is either generated based on a received cell-specific parameter or are received from the network. In another embodiment, the eNB, upon detecting the collision in Msg3, indicates a lowered MCS level for the Msg3 transmission in the RAR after the preamble detection. In another embodiment, the early termination of Msg3 transmission is used upon determining the collision of Msg3. In one embodiment, the eNB responds an ACK to a failed Msg3 to suspend the re-transmission of the Msg3. In another embodiment, the eNB sends a flag to cancel the mac-ContentionResolutionTimer and terminate the Msg3 transmission. The termination indication is either embedded in the acknowledgement signaling or sent through PDCCH signaling.

Abstract: Concepts and examples pertaining to efficient coding switching and modem resource utilization in wireless communication systems are described. A processor of a modem of a user equipment (UE), configured with at least a first-capacity decoder and at least a second-capacity decoder, receives a common virtual carrier (CVC), a dedicated virtual carrier (DVC), or both. The CVC contains common information shared by multiple UEs, control information for the UE, and/or data information related to first data destined for the UE. The DVC contains control information for the UE, the first data, or a combination thereof. The first-capacity decoder decodes data of a small size up to a low data rate. The second-capacity decoder decodes data of a large size up to a high data rate. The processor determines whether to decode the first data using the first-capacity decoder or the second-capacity decoder based on the data information in the CVC.

Abstract: A method of reporting UE measurement state information in RLF report is provided. A UE performs radio measurements of a serving cell and neighbor cells in a mobile communication network. The UE evaluates a measurement reporting criteria and attempts to access the network to deliver a measurement report if the criteria is met. The UE then detects a radio link failure or a handover failure event and reconnects to the network by performing RRC reestablishment or RRC establishment. Finally, the UE transmits a failure event report to the network. The failure event report comprises UE measurement state information corresponds to the failure event. The UE measurement state information helps the network to determine whether to apply corrective actions to mitigate the failure.

Abstract: Methods for UE measurement enhancement in an adaptive TDD configuration network are proposed. In a first solution, the network provides an adaptive TDD indicator to the UE. In a second solution, the network provides an instantaneous TDD configuration to the UE. In a third solution, multiple TDD configurations are grouped as one TDD group, and the network adapts TDD configurations within the same TDD group. In a fourth solution, the network broadcasts a TDD reference configuration in SIB1, and adapts to another TDD configuration with DL super set constraint, i.e., the DL subframes of the other TDD configuration form a super set of the DL subframes of the broadcasted TDD reference configuration.

Abstract: Methods and apparatus are provided contention based uplink data transmission. In one novel aspect, the contention-based uplink data channel is used to transmit the data directly to the network. In one embodiment, the UE selects an UL data channel from a set of preconfigured uplink contention based data channels and sends the UL data transmission on the selected UL data channel. In one embodiment, the contention based UL data has a narrow bandwidth with a long CP such that the TA is not needed from the base station. In another embodiment, a small signaling payload is included in the CB UL data transmission if the size of the data contents cannot be fit in the UL data channel. In one embodiment, the signaling payload is the BSR. The UE, subsequently, receives an UL grant and sends the remaining data contents using the allocated data channel in the UL grant.

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. The UE performs a Hybrid Automatic Repeat Request (HARQ) round trip time (RTT) timer counting for each downlink (DL) HARQ process based on the adaptive TDD configuration information. The UE can avoid the potential misunderstanding between eNB and UE regarding HARQ RTT timing when TDD configuration changes.

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.
