Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a resource grant for an uplink transmission of uplink information on a logical channel. The uplink information may be stored in an uplink buffer. The UE may initiate a buffer status report retransmission timer in response to receiving the resource grant. The UE may determine that the resource grant allocates resources that are sufficient to transmit a portion of the uplink information that satisfies a threshold. The UE may stop the buffer status report retransmission timer in response to the determining.

Abstract: In one aspect of the disclosure, a UE may receive a TA command in connection with a contention-based RACH procedure. In response to receiving the TA command, the UE may start a TA timer. The TA timer defines an interval during which subsequent TA commands received in connection with the contention-based RACH procedure are disregarded. The UE may detect an out-of-sync condition during the interval. The UE may stop the TA timer if the out-of-sync condition is detected. In another aspect, an eNB may perform a contention-based RACH procedure with a UE. The eNB may receive a reconfiguration complete message from the UE in connection with the contention-based RACH procedure. In response to the reconfiguration complete message, the eNB may send a TA command to the UE. The eNB may refrain from sending TA information prior to receiving the reconfiguration complete message.

Abstract translation: 在本公开的一个方面中，UE可以接收与基于争用的RACH过程相关的TA命令。 响应于接收到TA命令，UE可以启动TA定时器。 TA定时器定义了与基于竞争的RACH过程相关的后续TA命令被忽略的时间间隔。 UE可以在该间隔期间检测到不同步条件。 如果检测到不同步条件，则UE可以停止TA定时器。 另一方面，eNB可以与UE执行基于竞争的RACH过程。 eNB可以结合基于竞争的RACH过程从UE接收重配置完成消息。 响应于重配置完成消息，eNB可以向UE发送TA命令。 eNB可以在接收重配置完成消息之前避免发送TA信息。

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In aspects, the apparatus may be a user equipment (UE). However, the apparatus may be implemented as another wireless communications device, such as a base station (e.g., evolved Node B). The apparatus may determine that the apparatus is to operate in a low-latency mode. The apparatus may configure at least one layer of the apparatus to operate in the low-latency mode based on the determination that the apparatus is to operate in the low-latency mode. The apparatus may communicate with a network through the configured at least one layer.

Abstract: Various aspects of the disclosure relate to techniques for handling out-of-order grants. For example, upon detection of an out-of-order grant, the best scheduling policy for handing the out-of-order grants may be selected based on at least one traffic condition. In some aspects, a scheduling policy may involve canceling and regenerating out-of-order grants. In some aspects, a scheduling policy may involve reordering data units. In some aspects, a scheduling policy may involve designating a reorder time window.

Abstract: Methods, systems, and devices are described for access procedures in wireless communications. A user equipment (UE) may determine that a UE initiated access procedure with a first cell has been triggered. The first cell may be a primary cell. The UE may determine that a network initiated access procedure with a second cell is in progress. The second cell may be a secondary cell. The UE may cancel the UE initiated access procedure with the first cell based on the network initiated access procedure with the second cell.
