Abstract:
In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The method may be performed by a scheduling entity. The scheduling entity transmits control information in a control portion of the subframe, the control information corresponding to data information within the subframe, transmits the data information in a data portion of the subframe, receives a pilot signal from the set of subordinate entities in a pilot portion of the subframe, and receives an ACK/NACK signal from the set of subordinate entities in an ACK portion of the subframe. The ACK portion is subsequent to the pilot portion of the subframe. The ACK/NACK signal includes acknowledgment information corresponding to the data information. The control portion, the data portion, the pilot portion, and the ACK portion are contained in the same subframe.
Abstract:
Aspects of the present disclosure provide various wireless communication numerology designs that can maintain symbol boundary alignment while multiplexing different numerologies in wireless communication. The symbols may be scaled for different tone or subcarrier spacings while maintaining the symbol boundary alignment between different numerologies. Maintaining the symbol-boundary alignment between different numerologies enables symbol-level numerology multiplexing. The disclosed numerology designs enable low latency communication and improved interference management, and provide non-ambiguous symbol boundary timing reference for multiplexing different numerologies.
Abstract:
Certain aspects of the present disclosure relate to methods and apparatus for grant processing in uplink centric subframes. An example method generally includes transmitting a first subframe comprising a first grant that includes information for one or more transmissions on that allocated resources in the first subframe to a user equipment (UE) and transmitting the first subframe, with a second grant that allocates resources in at least a second subframe to occur after the first subframe. Other aspects, embodiments, and features are also claimed and described.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may monitor, in a first bandwidth part, of a plurality of bandwidth parts, associated with a first monitoring periodicity and in a downlink control channel, for a downlink control information (DCI) message. The user equipment may selectively transition, based at least in part on the DCI message, from the first bandwidth part to a second bandwidth part, of the plurality of bandwidth parts, associated with a second monitoring periodicity that is less than the first monitoring periodicity. Numerous other aspects are provided.
Abstract:
Some techniques and apparatuses, described herein, provide for resource allocation to achieve frequency diversity, time diversity, and/or spatial diversity for wakeup signals destined to two or more UE groups by transmitting the wakeup signals according to respective resource patterns associated with the two or more UE groups. Additionally, some techniques and apparatuses described herein provide for resource allocation to achieve spatial diversity for wakeup signals for a single UE group by transmitting the wakeup signals using two or more antenna ports according to respective resource patterns associated with the two or more antenna ports. Furthermore, some techniques and apparatuses described herein provide configurations for wakeup signals based at least in part on delays or gaps, repetitious communications, synchronization in accordance with a power level of the wakeup signal, and the like.
Abstract:
Aspects of the disclosure relate to wireless communications utilizing discontinuous reception (DRX). Disclosed methods and apparatus include providing a grant indicator in a transmission from a base station to a user equipment (UE), where indicator notifies the UE of a grant of data during a subsequent discontinuous reception (DRX) cycle in the at least one UE. Additionally, a tracking reference signal (TRS), which may be aperiodic (A-TRS), is transmitted prior to an on-duration time of the DRX cycle, where the TRS is usable by the UE for updating a tracking loop and also can be referenced by the indicator. In this manner, the combination of the grant indicator and the TRS affords a UE sufficient time for updating a UE tracking loop before the DRX cycle. Other aspects, embodiments, and features are also claimed and described.
Abstract:
Aspects described herein relate to measuring cross-link interference in wireless communications. A portion of a slot that includes a downlink reference signal transmitted by a base station and an uplink reference signal transmitted by a user equipment (UE) can be determined, where the uplink reference signal and the downlink reference signal at least partially overlap within the portion of the slot. The downlink reference signal can be received from the base station and the uplink reference signal can be received from the UE in the portion of the slot. Cross-link interference between the downlink reference signal and the uplink reference signal can be measured.
Abstract:
Certain aspects of the present disclosure generally relate to techniques for on-demand paging. In one aspect, a method is provided for receiving a paging message by a mobile device. The method generally includes acquiring network time, determining, based on the network time or an internal timer, that the mobile device is within a paging window wherein the mobile device can receive a paging message, and sending an indication message, in response to the determination. The mobile device may receive a response to the indication message, the response indicating whether or not there is a paging message for the mobile device.
Abstract:
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.
Abstract:
Various aspects described herein relate to transmitting hybrid automatic repeat/request (HARQ) feedback. A HARQ communication can be received over a set of one or more links based on a first scheduling grant. One or more interference parameters related to receiving the HARQ communication can be determined as well as one or more predicted interference parameters for a next HARQ communication. HARQ feedback can be transmitted for the HARQ communication including the one or more interference parameters and the one or more predicted interference parameters.
