    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. An eNB transmits pre-grant(s) to a UE(s) for a target resource on a contention-based carrier. In response, the UE(s) perform a CCA/eCCA and, when successful, transmit a preamble to the eNB based on the pre-grant. The eNB detects the preamble(s) and transmits grant confirmation(s) to the UE(s) for which a preamble was detected. The grant confirmation(s) may modify the pre-grant(s). The eNB may overschedule a target resource and based on the received preambles may transmit grant confirmation(s) that instruct a portion of the UEs for which a preamble was received to transmit data on a target resource and may instruct the remaining portion of the UEs for which a preamble was received to cease or modify data transmission.

    Abstract translation: 提供了一种用于无线通信的方法,装置和计算机程序产品。 eNB在基于竞争的运营商上向目标资源的UE发送预授权。 作为响应,UE执行CCA / eCCA,并且当成功时,基于预授权向eNB发送前导码。 eNB检测到前导码,并向被检测到前同步码的UE发送许可证确认。 授予确认可以修改预授权。 eNB可以调度目标资源,并且基于所接收的前导码可以发送指示接收到前导码的UE的一部分的授权确认,以在目标资源上发送数据,并且可以指示UE的剩余部分 接收到序言以停止或修改数据传输。

    Abstract: Aspects of the disclosure provide for an access terminal configured to enable communication with two or more wireless communications networks simultaneously. According to some aspects of the disclosure, an access terminal (e.g., dual-SIM access terminal) can be active simultaneously on both networks with reduced interference between transmission and reception. A number of different techniques for mitigating desense on a victim's Rx are illustrated in this disclosure with a GSM aggressor and an EV-DO victim as non-limiting examples. Other aspects, embodiments, and features are also claimed and described

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, and a network entity may receive, multiple physical random access channel (PRACH) signals at multiple power levels during a time period. The multiple power levels may be randomly or pseudo-randomly selected from within a power range defined for the PRACH signals. The UE may receive a response message indicating one or more of the PRACH signals of the multiple PRACH signals detected during the time period. The UE may transmit a random access request message at a first power level of the multiple power levels according to the one or more PRACH signals of the multiple PRACH signals detected during the time period.

    Abstract: PDCCH/PDSCH multiplexing with PDSCH data rate control is described. An apparatus is configured to receive, from a network node, DL signaling that indicates a MCS update, for a future time period, of a MCS associated with a PDSCH transmission that is multiplexed with a PDCCH transmission that includes information to schedule the PDSCH transmission. The apparatus is configured to demodulate data from the PDSCH transmission, after beginning the future time period, based on the MCS update. Another apparatus is configured to provide, for a UE, DL signaling that indicates a MCS update, for a future time period, of a MCS associated with a PDSCH transmission that is multiplexed with a PDCCH transmission that includes information to schedule the PDSCH transmission. The apparatus is configured to provide, for the UE, modulated data associated with the PDSCH transmission, after beginning the future time period, based on the MCS update.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may participate in sidelink communication using a sidelink slot structure that includes a set of periodic automatic gain control (AGC) candidate transmission time intervals (TTIs) that are common across a wireless network. The UE may monitor for a sidelink message during an interval in accordance with the set of common, periodic AGC TTIs, and the UE may transmit a sidelink feedback message in response to the sidelink message. The UE may transmit the sidelink feedback message over a set of resource blocks (RBs) of the sidelink slot structure if a format of the sidelink feedback message is associated with an uplink control channel format 0. Alternatively, the UE may transmit the sidelink feedback message over more than two symbols of the sidelink slot structure if the format is associated with an uplink control channel format 2.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a random access preamble according to a cyclic shift from a first set of cyclic shifts associated with a cyclic shift step size that is less than a round trip time (RTT) of a serving cell of the UE. The UE may generate the first set of cyclic shifts based on a second set of cyclic shifts and a set of cyclic shift offsets associated with an offset step size that is less than the RTT. If a network entity detects a collision between the random access preamble and another random access preamble, the network entity may transmit a collision resolution message indicating resources for the UE to retransmit the random access preamble. Alternatively, the network entity may proceed with the random access procedure by transmitting a random access response message to the UE.

    Abstract: Methods, systems, and devices for wireless communication are described. A communication device may receive control signaling indicating a beam configuration. The communication device may select a first beam (for example, a sensing beam) for wireless communication based on the beam configuration. The first beam including a first beam gain and a first pointing direction. The communication device may select a second beam (for example, a transmitting beam) based on the beam configuration. The second beam including a second beam gain and a second pointing direction. The communication device may determine (for example, adjust) an energy detection threshold (EDT) associated with the second beam based on the second beam gain in the first pointing direction and the first beam gain in the first pointing direction. The communication device may sense a channel using the second beam and the EDT associated with the second beam.
