Abstract: A user equipment (UE) can connect to an evolved universal terrestrial radio access network (E-UTRAN) new radio (NR) dual-connectivity (EN-DC) network using both a Long Term Evolution (LTE) anchor link and a 5G NR non-anchor link. The UE shares RF chain components (e.g., antennas) between the LTE and NR links. The UE uses various techniques for controlling or modifying NR sounding reference signal (SRS) transmissions and/or LTE operations to avoid interruption on LTE operations due to NR SRS transmissions.

Abstract: Examples described herein relate to enhancing data communication performance in a wireless communication network including a first subscription associated with a first radio access technology (RAT) and a second subscription associated with a second RAT, where the wireless communication device uses a same radio frequency (RF) resource to communicate over both the first RAT and the second RAT. The first RAT is used, in part, for data operations while the second RAT is used, in part, for voice operations. During idle state voice operations, the RF resource is reallocated from performing data operations to performing idle state voice operations, causing interruptions in the data operations. The wireless communication device adjusts at least one or a duration and an occurrence of the idle state voice operations to reduce the impact on the data operations.

Abstract: Various aspects of the disclosure provide a method of operating a user equipment (UE) to determine and report a throughput enhancing channel quality indicator (CQI) value when a physical channel between the UE and a base station is temporally uncorrelated. Reporting such CQI value may maximize the throughput of the channel when it remains temporally uncorrelated. In one aspect of the disclosure, the UE communicates with a base station utilizing a channel and determines that the channel is temporally uncorrelated. The UE further determines a plurality of CQIs in a first CQI reporting mode and computes the respective throughputs of the channel based on the plurality of CQIs. In addition, the UE selects a CQI of the plurality of CQIs corresponding to the highest throughput among the plurality of throughputs, and reports the selected CQI to the base station in a second CQI reporting mode while the channel remains temporally uncorrelated.

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 ε 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 ε. 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: The present disclosure presents a method and apparatus for regaining service at a user equipment. For example, the disclosure presents a method for receiving a neighbor cell list from a serving cell, and scanning to identify target cells by the user equipment, wherein the target cells include neighbor cells included in the neighbor cell list and detected cells not included in the neighbor cell list. In addition, such an example method may include determining that the user equipment cannot successfully camp on any one of the neighbor cells, and attempting to camp on one of the detected cells. As such, an improved method and apparatus for regaining service at a user equipment may be achieved.
