Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the present disclosure relate to retransmissions of data within wireless communication networks. For a retransmission, at least a portion of the encoded bits of an original transmission may be mapped to different bit locations in one or more modulated symbols based on a non-random mapping rule. In some examples, the encoded bits of a symbol may be reversed within the symbol for a retransmission. In other examples, the first and last encoded bits within a symbol may be switched for a retransmission. Other non-random mapping rules, such as a bit location offset, may also be used to map encoded bits to different bit locations in the modulated symbol within a retransmission.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Techniques are described herein for performing out-of-order processing. The UE may receive a first downlink channel at a first time and a second downlink channel at a second time. The UE may determine that a priority of the second downlink channel is different (e.g., higher) than a priority of the first downlink channel. The UE may determine that a first uplink transmission associated with the first downlink channel is to be transmitted after a second uplink transmission associated with the second channel based on the different priorities. The UE may set one or more operations based on these determinations. In some cases, the UE may suspend processing the of the first downlink channel to process the second downlink channel.

Abstract: Device detection in networks with mixed mobility devices is discussed. Devices in the network first determine a discovery mode from a plurality of discovery modes, wherein the determining is based on a mobility state of the wireless device. The device identifies a set of resources associated with the determined discovery mode, wherein each of the plurality of discovery modes is provisioned with separate resources. A discovery signal is transmitted using the identified set of resources according to the discovery mode. Thus, devices with higher mobility will generally send discovery signals more often than devices that are static or semi-static.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use a measurement procedure for beam detection within an existing cell. The UE perform a search procedure for a first synchronization signal block (SSB) to detect a first beam of a base station. The UE may determine a first timing offset for the first SSB based on the search procedure. The UE may estimate a second timing offset for a second SSB from the base station based on the first timing offset. The UE may perform a measurement procedure for the second SSB to detect a second beam of the base station based on the second timing offset. The UE may prune fake beams based on synchronization signals used for the measurement procedure.

Abstract: Certain aspects of the present disclosure provide techniques for beam management using adaptive learning. Certain aspects provide a method that can be performed by a node, such as user equipment (UE) or a base station (BS). The node determines one or more beams to utilize for a beam management procedure using adaptive learning. The node performs the beam management procedure using the determined one or more beams. In some aspects, the node uses an adaptive reinforcement learning algorithm to select beams for measurement in beam discovery procedure. The node may adaptive the beam management algorithm based on feedback associated with the beam selection, such as based on a throughput achieved using a beam pairing determined during the beam management procedure.

Abstract: Tracking reference signal designs for deployments without continuous reference signal transmission are described. The tracking reference signals may be extended in the frequency domain from a synchronization signal block and may occupy a subset or all of the symbol periods of the synchronization signal block. The tracking reference signals may have the same subcarrier spacing as synchronization signals and may be punctured in the frequency domain. Alternatively, the tracking reference signals may include common control reference signals transmitted periodically with paired reference signals in a data channel. The common control reference signals and paired reference signals may be transmitted regardless of the presence of control or data. For improved tracking after a transition to a connected mode or a long discontinuous reception (DRX) cycle, a slot including tracking reference signals may be repeated or an additional tracking reference signal pattern may be transmitted.
