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.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying a transmission timing of a control reference signal transmitted over a radio frequency spectrum band during an OFF duration of the UE with respect to the radio frequency spectrum band, in which the identified transmission timing is relative to a transition from the OFF duration to an ON duration of the UE with respect to the radio frequency spectrum band; receiving the control reference signal at the identified transmission timing; and performing a warm-up procedure, before the ON duration, based at least in part on the identified transmission timing of the control reference signal. A method for wireless communication at a wireless network includes indicating, to the UE, the transmission timing of the control reference signal; and transmitting the control reference signal at the indicated transmission timing. The OFF duration and the ON duration are coordinated with a wireless network.

Abstract: A method, an apparatus, and a computer-readable medium may be described in the present disclosure. The apparatus may be a user equipment. The apparatus may determine whether a number of unsuccessful repetitions associated with performance of a first type of scanning exceeds a repetition threshold. The apparatus may perform a second type of beam scanning based on the determination that the number of unsuccessful repetitions exceeded the repetition threshold.

Abstract: Aspects of the present disclosure provide apparatus and techniques that may be applied in systems that may help enable efficient communication between a base station (BS) and certain devices, such as wearable devices and/or machine type communication (MTC) user equipments (UEs), having a single receiver (RX) for long term evolution (LTE). An exemplary method, performed by a BS, generally includes receiving, from a UE, an indication of a category of the UE, wherein the category of the UE indicates at least one of: a maximum throughput supported by the UE or a number of layers supported by the UE; assuming a number of receivers at the UE based on the category of the UE; determining one or more transmit parameters based on the number of receivers of the UE; and communicating with the UE according to the one or more transmit parameters.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may identify a duration of a slot used for communications with a receiving device. The transmitting device may determine that the communications with the receiving device comprises frequency division duplexing (FDD) communications. The transmitting device may transmit communications to the receiving device during a first portion of the slot, a duration of the first portion being less than the duration of the slot and the duration of the first portion is based at least in part on the determination that the communications comprise FDD communications. The transmitting device may select, based at least in part on the determination that the communications comprise FDD communications and that the communications are transmitted during the first portion of the slot, a hybrid automatic repeat request (HARD) scheme to use during the communications.
