Abstract: To reduce power consumption, a user equipment (UE) may trigger a microsleep in a subframe when a physical downlink control channel (PDCCH) does not include a downlink grant. However, because the microsleep depends on the PDCCH not including a downlink grant, the UE cannot trigger the microsleep until after the PDCCH is decoded. Accordingly, in some aspects, a UE may enable an aggressive extra microsleep in which a microsleep duration may be increased by reducing a PDCCH decode time. For example, a UE may use a stale channel estimate and noise estimate from a previous subframe to perform PDCCH demapping when conditions related to a PDCCH block error rate are satisfied. In this way, removing channel estimation and noise estimation from a PDCCH demapping path may reduce the PDCCH decode time, whereby the UE may trigger a microsleep sooner to increase a sleep ratio and thereby increase power savings.

Abstract: Fast Associated Control Channel (FACCH) information is combined if a first block of FACCH information and a repeated block of FACCH information each fail a respective integrity check. An algorithm for realizing repeated FACCH diversity combining gains for different codec and discontinuous transmission (DTX) configurations is applicable to Full Rate codecs, Half Rate codecs, and discontinuous transmission scenarios. A pair of buffers may be used in a ping-pong fashion to store decoding soft or hard decisions for failed FACCH blocks.
Abstract translation: 如果FACCH信息的第一块和FACCH信息的重复块各自失败相应的完整性检查，则组合快速关联控制信道（FACCH）信息。 用于实现用于不同编解码器和不连续传输（DTX）配置的重复FACCH分集组合增益的算法适用于全速率编解码器，半速率编解码器和不连续传输场景。 可以以乒乓方式使用一对缓冲器来存储针对故障FACCH块的解码软或硬判决。

Abstract: Access terminals are adapted to blacklist one or more neighboring cells from acquisition attempts. For instance, an access terminal may receive a transmission including a list of neighboring cells to be monitored while connected to a particular serving cell. The access terminal may determine that a predefined number of consecutive acquisition attempts with a particular neighboring cell have failed. In response to failure of the predefined number of consecutive acquisition attempts, the access terminal can blacklist the neighboring cell from subsequent acquisition attempts for a predefined blacklisting period. Following the duration of the blacklisting period, the access terminal may conduct a subsequent acquisition attempt with the neighboring cell. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE starts a first timer (such as a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer), after sending an uplink (UL) data transmission to a network entity. The UE then starts a second timer (such as a DRX retransmission timer) when the first timer expires. The UE then determines whether to wake up or sleep for a duration of the second timer based on a prior block error rate (BLER).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, based at least in part a determination to transmit one or more packets, a scheduling request (SR) occasion in which to transmit an SR for uplink resources to transmit the one or more packets, the SR occasion occurring prior to a start of a connected discontinuous reception (CDRX) on duration of the UE. The UE may determine whether the SR occasion occurs within a threshold amount of time prior to the start of the CDRX on duration of the UE. The UE may transmit the SR in the SR occasion based at least in part on the determination of whether the SR occasion occurs within the threshold amount of time prior to the start of the CDRX on duration of the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

Abstract: Access terminals are adapted to employ timing information for a Synchronization Channel (SCH) associated with a neighboring base station during a re-acquisition procedure after such timing information has been determined to be inaccurate, or potentially inaccurate. For instance, an access terminal can obtain timing information for a Synchronization Channel (SCH) associated with a neighboring base station, such as by means of a combined acquisition procedure. The access terminal may subsequently determine that the obtained timing information is, or appears to be, no longer synchronized with the base station. In response to such a determination, the access terminal can employ the obtained timing information to time the opening of a receive window for re-acquiring the base station. Other aspects, embodiments, and features are also claimed and described.
