摘要： The disclosure relates in some aspects to an energy-aware architecture that supports a low power scheduling mode. For example, a media access control (MAC) architecture for a base station (e.g., an enhanced Node B) and associated access terminals (e.g., UEs) can take the power needs of the access terminals into account when scheduling the access terminals. In some aspects, an access terminal may support a particular frame structure for a low power mode. Accordingly, scheduling of the access terminal may include use of the particular frame structure during low power mode.

摘要： A method, apparatus, or computer-readable medium with instructions for beam management for radio frequency (RF) sensing at a wireless device. The wireless device performs a first beamsweep of an RF signal and measures a reflection of the RF signal based on the first beamsweep. The wireless device performs a second beamsweep of the RF signal, wherein the first beamsweep is based on a different parameter than the second beamsweep and measures the reflection of the RF signal based on the second beamsweep. The wireless device selects a beam for RF sensing based on the first beamsweep and the second beamsweep.

摘要： Disclosed are techniques for transmitting and processing reference signals for positioning estimation over a multipath multiple-input multiple-output (MIMO) channel. In aspects, a first node configures first and second reference signal resource sets for transmission of first and second sets of reference signals, wherein the first and second reference signal resource sets occur on first and second subbands of, and/or during first and second time intervals on, the MIMO channel, wherein each reference signal resource in the first and second reference signal resource sets utilize at least first and second MIMO precoders, and transmits, to a second node over the MIMO channel, the first and second sets of reference signals, wherein the first node transmits the first and second sets of reference signals to assist the second node to perform a positioning measurement based on joint processing of the first and second sets of reference signals.

摘要： Certain aspects of the present disclosure relate to techniques and apparatus for efficient support of connected discontinuous reception (C-DRX) by using a wireless device (e.g., a user equipment (UE)) with a second receiver. A wireless device with two receivers may place one receiver in a low power mode and take the receiver out of the low power mode in response to a signal received from a serving base station (BS) of the wireless device. A BS may direct a wireless device to enter a low power DRX (LP-DRX) mode or enhanced DRX mode having longer low power cycles than a non-enhanced DRX mode, and the wireless device may place a primary receiver in a low power mode in response to the directive from the BS. Other aspects, embodiments, and features are also claimed and disclosed.

摘要： The disclosure relates in some aspects to techniques for improved channel estimation. For example, a device can specify a pilot structure where pilot density differs over time. As another example, a device can indicate that a pilot from a prior transmission time interval (TTI) can be used for channel estimation. As another example, a device can employ frequency domain physical resource block (PRB) bundling with the bundling information signaling. As yet another example, a device can use an adjustable traffic-to-pilot ratio (TPR) for throughput optimization. Other aspects, embodiments, and features are also discussed and claimed.

摘要： Wireless communication devices are adapted to facilitate transmission and reception of non-orthogonal communications. In one example, wireless communication devices can encode an amount of data in accordance with information that at least some of the data will be transmitted as part of a non-orthogonal transmission. The wireless communication device may further transmit the encoded data, and the encoded data can be non-orthogonally combined as part of a non-orthogonal transmission. In another example, wireless communication devices can receive a wireless transmission including a plurality of data streams non-orthogonally combined together. The wireless communication device may decode at least one of the data streams. Other aspects, embodiments, and features are also included.

摘要： Aspects of the present disclosure relate to wireless communications and, more particularly, to linkage of packet transmissions for ultra-reliable low-latency communications (URLLC) in new radio (NR). A method for wireless communications that may be performed by a user equipment (UE) is provided. The method generally includes receiving a current transmission of a packet; determining, based on the current packet transmission, one or more previous transmissions of the packet occurred and at least one parameter associated with the one or more previous transmissions; and combining the current packet transmission with the previous transmissions based, at least in part, on the determination.

摘要： Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

摘要： Aspects of the present disclosure provide a time division duplex (TDD) subframe structure that supports both single and multiple interlace modes of operation. In a single interlace mode, control information, data information corresponding to the control information and acknowledgement information corresponding to the data information are included in a single subframe. In a multiple interlace mode, at least one of the control information, the data information corresponding to the control information or the acknowledgement information corresponding to the data information is included in a different subframe. Both single and multiple interlace modes can be multiplexed together within the TDD subframe structure.
