摘要： Techniques for uplink transmission management in a wireless communications system are described herein. An example method may include receiving an explicit uplink grant that indicates one or more implicit uplink grants. In an aspect, the example method may include performing a first clear channel assessment (CCA) in response to the explicit uplink grant in a first time slot. In another aspect, the example method may include, if the first CCA fails, sequentially performing one or more additional CCAs respectively in one or more time slots subsequent to the first time slot in response to the one or more implicit uplink grants, and transmitting the PDU over the unlicensed or shared spectrum and in a time slot subsequent to the time slot in which one of the one or more additional CCAs succeeds.

摘要： An apparatus may receive signaling from a base station that indicates different tone indices. The apparatus may further transmit a plurality of symbols in a single tone uplink transmission. In an aspect, groups of symbols in the plurality of symbols are transmitted using the different tone indices of the single tone uplink transmission indicated by the received signaling. A second apparatus may signal to at least one user equipment (UE) information associated with different tone indices for use in transmitting a plurality of symbols in a single tone uplink transmission. The second apparatus may further receive the plurality of symbols in the single tone uplink transmission. In an aspect, pairs of symbols in the plurality of symbols are received in different tone indices of the single tone uplink transmission.

摘要： Certain aspects of the present disclosure provide methods for wireless communications by a base station and a user equipment in a network. An exemplary method generally includes performing a discovery procedure to identify one or more devices through which the UE may indirectly communicate with a base station in the network and deciding based on one or more criteria whether to communicate with the base station directly or to communicate with the base station indirectly via a device identified by the discovery procedure. According to certain aspects, when a UE is in communication with a network indirectly, the network might page the UE directly, indirectly, or both.

摘要： A method, an apparatus, and a computer readable-medium for wireless communication are provided. The apparatus receives data via a first group of component carriers (CCs) of a plurality of groups of aggregated CCs. The first group of CCs correspond to unlicensed or shared frequencies. The apparatus selects a CC from at least two CCs of the first group of CCs for transmission on a physical uplink control channel (PUCCH). The selection of the CC is based on at least an uplink-transmission clearance status of each of the at least two CCs. The apparatus transmits the PUCCH via the selected CC.

摘要： Various aspects described herein relate to communicating a scheduling request (SR) in a wireless network. A frame structure that allows dynamic switching of transmission time intervals (TTI) between uplink and downlink communications may be used to communicate with a network entity. At least one SR mode can be selected for SR transmission to the network entity in one or more of the TTIs configured for uplink communications based at least in part on the frame structure. The SR can be transmitted to the network entity in at least one uplink TTI of the one or more TTIs configured for uplink communications based at least in part on the at least one SR mode.

摘要： Certain aspects of the present disclosure relate to techniques and apparatus for efficient support of variable bit rate (VBR) voice traffic on LTE uplink. In an aspect, a base station may periodically schedule transmission resources for use by a user equipment (UE) for transmitting data on a logical channel, wherein the periodically scheduling grants the UE a fixed first transport block (TB) size of transmission resources at regular intervals, receive an indication from the UE of an amount of data for transmission on the logical channel, and adjust the fixed first TB size of the periodically scheduled transmission resources to a fixed second TB size based on the indicated amount of data. In another aspect, a base station may configure a UE to enable scheduling request masking (SR-masking) on a logical channel, and configure the UE with a threshold amount of data for the logical channel to dynamically disable SR-masking on the logical channel. In another aspect, a UE may receive a configuration to enable scheduling request (SR) masking (SR-masking) on a logical channel, receive a configuration of a threshold amount of data for the logical channel to dynamically disable SR-masking on the logical channel, and decide whether to transmit an SR based on the amount of data to transmit and the threshold amount.
