Abstract:
A communications apparatus includes a radio transceiver and a processor. The radio transceiver receives a plurality of feedback messages from a peer device. The feedback messages are transmitted by the peer device to indicate a result of UL data transmission. The processor analyzes content of the feedback messages to determine a preferred retransmission type of the peer device and records the preferred retransmission type of the peer device in a memory device. When the radio transceiver receives a first UL grant message indicating transmission of a first UL data and the processor determines that a forthcoming first feedback message corresponding to the transmission of the first UL data is unable to be received, the processor determines whether to retransmit the first UL data according to the preferred retransmission type of the peer device.
Abstract:
A wireless communication method and device are provided. The wireless communication method includes the steps of activating a power-saving mechanism by user equipment (UE) to stop monitoring a Physical Downlink Control Channel (PDCCH) when a network does not enable a Discontinuous Reception (DRX) mechanism to configure the UE to switch to a DRX mode or when the network disables the DRX mechanism.
Abstract:
A communications apparatus includes a first radio frequency (RF) signal processing device, a first baseband signal processing device and a processor. The first RF signal processing device transceives a plurality of RF signals to and from a peer communications apparatus to communicate with the peer communications apparatus in compliance with a first Radio Access Technology (RAT) and processing the RF signals. The first baseband signal processing device processes a plurality of baseband signals corresponding to the RF signals. The processor obtains an uplink scheduling indicating a predetermined time assigned by the peer communications apparatus to transmit uplink data from the baseband signals, determines whether to transmit the uplink data at the predetermined time according to a gap-creation criterion, and transmits padding instead of the uplink data to the peer communications apparatus at the predetermined time when the gap-creation criterion is satisfied.
Abstract:
Aspects of the disclosure provide a method for reducing power consumption of a wireless communication device. The method can include receiving a discontinuous reception (DRX) configuration specifying a DRX having a DRX cycle, receiving an original scheduling request (SR) configuration specifying an original SR period, selecting an extended SR period according to the DRX cycle, the extended SR period being a multiple of the original SR period and corresponding to a set of candidate SR offsets, determining for each of the set of candidate SR offsets an overlap between active times caused by the DRX and active times caused by SR transmissions corresponding to the extended SR period, and selecting one of the set of the candidate SR offsets having a largest overlap to determine a period-extended SR configuration including the selected extended SR period and the selected SR offset.
Abstract:
The wireless communication methods for avoiding HFN asynchronism between wireless communications device and network are provided. One of the wireless communication methods includes the steps of defining a receiving window; and determining whether to discard a PDU according to a sequence number (SN) of the PDU and the receiving window.
Abstract:
A timing control method for a user equipment (UE) in a wireless communications system, including: obtaining a starting time of a data transmission period from information of a data transmission timing received from a base station of a wireless network; obtaining a starting time of a current data processing period; and adjusting a data processing timing so that the adjusted starting time of the current data processing period is ahead of the starting time of the data transmission period by a predetermined time.
