Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for dynamic transmit power adjustment, the processing circuitry is to decode baseband configuration information received from a base station. The baseband configuration information including at least a modulation and coding scheme (MCS), resource block (RB) allocation, and carrier assignment for uplink (UL) transmission and downlink (DL) reception. A communication mode is selected based on the baseband configuration information. An additional maximum power reduction (A-MPR) is determined based on the baseband configuration information and the selected communication mode. UL data is encoded for transmission to the base station via the selected communication mode and using transmit power adjusted based on the determined A-MPR. New signaling enhancements between the UE and the network (on a Uu interface) and between two UEs (on a PC5 sidelink interface) are also disclosed.

Abstract: Aspects of the present disclosure provide adaptive radio link monitoring for machine type communication(s) (MTC), enhanced MTC (eMTC), and/or narrowband Internet-of-Things (NB-IoT). In one aspect, a method is provided which may be performed by a user equipment (UE). The method generally includes receiving a first configuration of parameters for receiving downlink control channel signaling, the first configuration of parameters associated with a first coverage level; measuring at least one parameter related to channel conditions; determining one or more dynamic radio link monitoring (RLM) threshold values for the at least one parameter based, at least in part, on the first configuration of parameters; and performing RLM functions based on the one or more dynamic RLM threshold values. The threshold may comprise early out thresholds that occur before out-of-sync (OOS) or in-sync thresholds. The thresholds may be determined using lookup tables.

Abstract: Aspects of the present disclosure provide techniques and apparatus for user equipment initiated handover.

The method further includes determining that the second signal metric is stronger than the first signal metric. The method further includes declaring a radio link failure with the first base station based on determining that the second signal metric is stronger than the first signal metric. The method further includes establishing a connection with the second base station.

Abstract: Aspects of the present disclosure provide an apparatus and methods for recovering data from a control channel in wireless communications. An apparatus decodes a CRC appended codeword to obtain a decoded codeword, and computes a first syndrome of the decoded codeword utilizing a parity check matrix. If the first syndrome is non-zero, The apparatus determines a location S and a length K of an error pattern in bits of the decoded codeword, an index set ? based on the values of S and K. A linear system is formed based on the parity check matrix and the error pattern in accordance with the index set ?. The apparatus determines a solution of the linear system, wherein the solution includes an estimated error pattern. A recovered codeword can be determined by removing the estimated error pattern from the decoded codeword.

Abstract: UEs are adapted to facilitate reconstruction of a segment of corrupted bits. According to one example, a UE can receive a control channel transmission such as a HS-SCCH transmission. The control channel transmission may include a plurality of information bits and a plurality of cyclic redundancy check (CRC) bits. The UE may further determine that a contiguous segment of the received information bits is corrupt. The UE may accordingly utilize the uncorrupted information bits and CRC bits to reconstruct the corrupt information bits. In some instances, the UE may utilize the uncorrupted bits to reconstruct the corrupt information bits using a new generator polynomial. In other instances, the UE may utilize the uncorrupted bits to reconstruct the corrupt information bits using the original generator polynomial.

Abstract: A method and apparatus for compensating for phase noise of symbols spread with a long spreading code are disclosed. To compensate for the phase noise, a phase error estimate is generated from despread symbols with a short spreading code. A phase correcting phasor is applied to chip rate data before despreading the data with a long spreading code. A signal-to-interference ratio (SIR) on a common pilot channel (CPICH) may be calculated by spreading the data with a parent spreading code in an orthogonal variable spreading factor (OVSF) code tree and by combining symbols. Alternatively, a magnitude of the symbols may be used in estimating the SIR. The SIR of a channel using a short spreading code and an SIR of a channel using a long spreading code are measured. The SIR of the channel with the long spreading code may be compensated in accordance with a difference between degradation of the SIRs.
