Abstract: This disclosure provide various techniques for improving the quality of a signal. By integrating phase-shifting circuitry with a transmit/receive (T/R) switch, insertion loss may be reduced while decreasing space consumed on an integrated circuit or printed circuit board. In particular, embodiments disclosed herein include a transmitter and a receiver, each including one or more differential amplifiers coupled to a first inductor, and a switching network coupled to a second inductor and one or more phase-shifting circuitries. A differential interface of the differential amplifiers may enable integration of a stage of the phase shifter (e.g., a 180 degree stage) with the T/R switch, such that a single circuit may operate as the phase shifter and the T/R switch. This implementation may reduce the number of T/R switches and phase shifter stages in the phased array system, reducing the overall insertion loss experienced by the phased array system.
Abstract: A head-mountable device can operate in concert with one or more optical assemblies thereof to provide multiple users with shared experiences and content enjoyment. Such operations can be facilitated by a connection between the head-mountable device and one or both of its optical assemblies to allow different users to receive content. Such a connection can be made possible by a communication link that directly and/or physically connects the head-mountable device and one or both of its optical assemblies when the one or both of the optical assemblies is removed from the head-mountable device for operation by a separate user. The ability to provide multiple outputs on separate components allows separate users to participate in a shared experience.
Abstract: Herein described are apparatuses, systems, and methods for measurement and reporting of channel state information within wireless network systems. In embodiments, an apparatus for a user equipment (UE) may include memory to store a rank indicator (RI), a precoding matrix index (PMI), and a channel quality indicator (CQI) of channel state information (CSI) for the UE. The apparatus may further include circuitry to concatenate the RI, the PMI, and the CQI to produce a concatenated CSI element, generate a CSI report that includes the concatenated CSI element, and cause the CSI report to be transmitted to a base station within a single slot. Other embodiments may be described and/or claimed.
Abstract: Methods and apparatuses are disclosed for signaling unused channel occupancy time (COT) to the gNB for COT sharing among other UEs. Upon determining that a portion of the maximum COT (MCOT) provided to the UE will be unused, the UE can generate COT sharing information for transmission back to the gNB. The COT sharing information identifies a starting point and a duration (e.g., a number of consecutive slots) of the unused portion of the MCOT. This information is then encoded into configured grant uplink control information (UG-UCI) and transmitted to the gNB as part of the uplink transmission. In aspects, the unused portion may begin part-way through a slot. In this instance, a starting symbol of the unused portion or an ending symbol of the used portion may also be encoded into the uplink transmission. In this manner, unused COT is not wasted, but rather repurposed by the gNB.

Abstract: A bitstream is obtained by a decoder side, that contains an encoded version of an audio signal and an instantaneous loudness sequence of the audio signal. The instantaneous loudness sequence has not been loudness normalized. A dynamic range control, DRC, gain sequence is produced by applying the instantaneous loudness sequence to a DRC characteristic, with loudness normalization. The DRC gain sequence is applied to the decoded audio signal. Other aspects are also described and claimed.
Abstract: Systems of the present disclosure can provide a head-mountable device with a head securement element that allows a user to adjust how the head securement element fits near the ears of the user. Examples of adjustment mechanisms described herein allow a user to control the size, shape, flexibility, and/or position of certain regions of the head securement element with respect to the ears of the user. Accordingly, the user can select a configuration that distributes forces evenly, maximizes comfort, and allows the user to enjoy the head-mountable device for longer durations of time.

Abstract: Techniques are disclosed relating to multi-block fetches for cache misses. In some embodiments, cache tag circuitry maintains a tag value that is shared by multiple cache blocks. In response to a miss, the cache may initiate a fetch request to a next level cache or memory. Aggregation circuitry may aggregate multiple fetch requests for cache blocks that share the tag value and fetch circuitry may initiate a single multi-block fetch operation to the next level cache or memory that returns cache blocks for the aggregated multiple fetch requests. In various embodiments, disclosed techniques may improve performance (e.g., by reducing fetch bus transactions), reduce power consumption, or both, relative to traditional techniques.
Abstract: Systems and methods using control signaling for uplink frequency selective precoding at a user equipment (UE) are disclosed herein. A base station may indicate a transmission rank indicator (TRI), a wideband transmission precoder matrix indicator (TPMI), and one or more subband TPMI(s) to the UE. The base station may indicate, to the UE, whether to use the wideband TPMI or a subband TPMI to precode a physical uplink shared channel (PUSCH) transmission from the UE to the base station. The UE then precodes (and transmits) the PUSCH accordingly. Methods of UE application of the indicated subband TPMI(s) to subbands of the bandwidth in which a PUSCH may be transmitted are described. Methods accounting for a UE capability as to non-coherent, partial-coherent, and/or coherent precoding are described. Methods of assigning TPMI(s) to subbands in view of multiple transmission reception point (TRP) use by the UE for UE transmission are described.

Abstract: A method for performing multi-touch (MT) data fusion is disclosed in which multiple touch inputs occurring at about the same time are received to generating first touch data. Secondary sense data can then be combined with the first touch data to perform operations on an electronic device. The first touch data and the secondary sense data can be time-aligned and interpreted in a time-coherent manner. The first touch data can be refined in accordance with the secondary sense data, or alternatively, the secondary sense data can be interpreted in accordance with the first touch data. Additionally, the first touch data and the secondary sense data can be combined to create a new command.
