    Abstract: Wireless communication techniques that include techniques for handover or redirection of a UE from 4G network service to 5G (SA) network service are discussed. A UE may determine that a RSRP associated with a second base station is less than a first threshold while the UE is registered in a first wireless communication network associated with a first base station. The UE may also trigger a registration procedure to register the UE in a second wireless communication network associated with the second base station upon determining that the RSRP associated with the second base station is greater than a second threshold. Other aspects and features are also claimed and described.

    Abstract: Fallback procedures for user equipments (UEs) described provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

    Abstract: Certain aspects of the present disclosure provide techniques and apparatus for low density parity check (LDPC) interleaving with improved error floor performance. A method for wireless communications that may be provided by a transmitting device is provided. The method generally includes encoding one or more information bits using a LDPC code to produce a coded bit sequence comprising systematic bits and parity bits. The transmitting device stores the coded bit sequence in a circular buffer. The transmitting device performs rate matching on the coded bit sequence. The rate matching includes interleaving the parity bits with a partial interleaver and interleaving the systematic bits and interleaved parity bits with a systematic bit priority mapping (SBPM) interleaver. The transmitting device maps the SBPM interleaved bit sequence to constellation points according to a modulation scheme and transmits the modulated bit sequence.

    Abstract: Methods, systems, and devices that support an efficient sequence-based polar code description are described. In some cases, a wireless device (e.g., a user equipment (UE) or a base station) may transmit a codeword including a set of information bits encoded using a polar code or receive a codeword including a set of information bits encoded using a polar code. As described herein, the wireless device may determine the bit locations of the information bits in the polar code based on a partition assignment vector. Specifically, the wireless device may partition bit-channels for one or more stages of polarization and assign information bits to partitions based on the partition assignment vector. Once the bit locations of the information bits are determined, the wireless device may decode a received codeword or transmit an encoded codeword based on the determined bit locations of the information bits.

    Abstract: Techniques for performing automatic gain control (AGC) at a terminal in a wireless communication network are described. In an aspect, the terminal may use different receiver gain settings to receive different types of signals in different time intervals. The terminal may determine a receiver gain setting for each signal type and may use the receiver gain setting to receive signals of that signal type. In another aspect, the terminal may determine a receiver gain setting for a future time interval based on received power levels for peer terminals expected to transmit in that time interval. The terminal may measure received power levels of signals received from a plurality of terminals. The terminal may determine a set of terminals expected to transmit in the future time interval and may determine the receiver gain setting for the future time interval based on the measured received power levels for the set of terminals.

    Abstract: Techniques for performing transmit power control based on receiver gain setting in a wireless communication network are described. In an aspect, a terminal A may estimate pathloss to another terminal B, e.g., based on a peer discovery signal received from terminal B. Terminal A may then determine a transmit power level for a peer-to-peer (PTP) signal (e.g., a paging signal) based on the estimated pathloss, a receiver gain setting at terminal B, and a target received power level for the PTP signal. Terminal A may send the PTP signal at the determined transmit power level to terminal B. In another aspect, terminal B may use different receiver gain settings in different time intervals to receive PTP signals from other terminals. Terminal A may then select a suitable time interval to send the PTP signal based on the pathloss and the different receiver gain settings used by terminal B.
