Abstract: A base station and mobile device (UE) may coordinate transmission of reference signals and reception of corresponding channel state information (CSI) reports. If a periodic reference signal is scheduled for transmission outside the on-duration period of the UE, even if the reference signal corresponds to a periodic CSI report scheduled to be transmitted by the UE during the on-duration period, the base station may not transmit the periodic reference signal, thereby allowing the UE not to prematurely exit a low-power state. The base station may instead transmit an aperiodic reference signal at a specified point in time later than the scheduled transmission of the periodic reference signal. The UE may receive the aperiodic reference signal and either transmit the periodic CSI report or an aperiodic CSI report in response, depending on how close to the start of the on-duration period the transmission of the periodic CSI report is scheduled.

Abstract: Apparatuses, systems, and methods for a base station to perform a method construct dynamic hierarchical sub-configurations of bandwidth parts (BWPs) for use in a connected mode discontinuous reception (CDRX) communication session with a user equipment (UE) device. The base station may configure a first BWP at a baseband frequency associated with the CDRX communication session as a default BWP, a second BWP with a wider bandwidth than the first BWP as a transmission BWP, and one or more third BWPs as resting BWPs.

The transmission BWP may be utilized, when activated to perform data transmission by UE device, and the one or more resting BWPs may be utilized, when activated, for performing channel measurements.

Abstract: This disclosure relates to techniques for opportunistically depowering receiver chains of a wireless device. Based on received control information, a device may determine a depowering time. For example, the device may determine a minimum number of symbols of the payload channel that will provide an effective spectral efficiency less than a supportable spectral efficiency of the payload channel. The depowering time may be determined as a time upon receipt of the determined minimum number of symbols. The device may determine whether to perform a depowering procedure, based upon the determined depowering time. In response to determining to perform the depowering procedure, the device may depower an RF receiver of the device at the depowering time, wherein the depowering time is prior to the end of the payload channel. The device may decode the payload channel based on a portion of the payload channel received by the RF receiver.

Abstract: A method for transmitting a packet from a transmitter to a receiver in a wireless communication system begins by building a packet by a transport format combination (TFC) selection process, and the packet is transmitted from the transmitter to the receiver. If the transmitter receives an indication that the packet was not successfully received at the receiver, the packet is retransmitted via a hybrid automatic repeat request (HARQ) procedure. If the HARQ procedure did not successfully transmit the packet, then the packet is retransmitted via a retransmission management (RM) procedure. If the RM procedure did not successfully transmit the packet, then the packet is discarded by the transmitter.

Abstract: A method and apparatus for transmitting a packet from a transmitter entity to a receiver entity in a wireless communication system are disclosed. A transmitting entity includes a radio link control (RLC) sublayer and lower layers including a medium access control (MAC) sublayer and a physical layer, where the RLC sublayer provides a protocol data unit (PDU) to the lower layers for transmission. The lower layers using a HARQ entity transmit the PDU to the receiving entity. The RLC sublayer in the transmitting entity, without an indication from an RLC sublayer of the receiving entity, provides the PDU in response to an indication from the lower layers for retransmission.
