Abstract:
A method can include determining candidate sidelink resources by a user equipment (UE) for sidelink transmission on an unlicensed band from a sidelink resource selection window based on results of a sensing operation on the unlicensed band during a sidelink sensing window, selecting a sidelink resource from the candidate sidelink resources, performing a listen-before-talk (LBT) process on the unlicensed band to obtain a channel occupancy time (COT), and performing a sidelink transmission within the COT using the first sidelink resource. The selection of the sidelink resource can be based on an LBT time that is a predicted duration of a random backoff process of the first LBT process. Also, the first sidelink resource can be selected from the candidate sidelink resources without randomization.
Abstract:
A method for reducing power consumption when a communications apparatus establishes voice communications with another communications apparatus includes estimating a voice quality perceived by a user of the another communications apparatus; determining whether the estimated voice quality is higher than a predetermined threshold; and adjusting at least one parameter utilized for processing a plurality of voice packets to be transmitted to the another communications apparatus according to the estimated voice quality to reduce the power consumption when the estimated voice quality is higher than the predetermined threshold.
Abstract:
A method for performing sidelink transmission over an unlicensed band is provided. The method includes performing a first-type listen-before-talk (LBT) process on the unlicensed band to obtain a channel occupancy time (COT) for the sidelink transmission. The first-type LBT process includes a random backoff process. Duration of the random backoff process is determined by a randomly generated LBT counter. The method further includes determining, based on a result from a sensing operation performed on the unlicensed band within a sensing window, a plurality of candidate sidelink resources on the unlicensed band within a sidelink resource selection window. The method also includes selecting, based on a completion time point of the first-type LBT process, a sidelink resource from the plurality of candidate sidelink resources. The method also includes performing the sidelink transmission within the obtained COT on the selected sidelink resource.

A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a cell. The controller receives first barring information and second barring information from the cell via the wireless transceiver, and ignores the first barring information in response to the UE supporting network-based Cell-specific Reference Signal (CRS) interference mitigation. Also, the controller allows the UE to access the cell in response to the UE supporting network-based CRS interference mitigation and the second barring information indicating that the cell is not barred.

A communications apparatus. A first radio module communicates with a first wireless network and provides wireless communications services. A second radio module communicates with a second wireless network and provides wireless communications services. At least two antennas shared by the first radio module and the second radio module. When the first radio module operates in a connected mode and when the timing of the first radio module performing the first receiving activity coincides with the timing of the second radio module performing a second receiving activity, the first radio module reports a value of 1 for a Rank Indicator to the first wireless network at least once before the second radio module is to perform the second receiving activity, and then the second radio module uses one of the antennas to perform the second receiving activity.

Abstract:
Aspects of the disclosure provide a method of data transmission that includes determining a transmission time interval for transmission of a transport block and setting a segmentation threshold for the transport block to a first threshold or a second threshold that is less than the first threshold based on the determined transmission time interval. The method includes converting the transport block into one or more outgoing code blocks that each has a size not greater than the determined segmentation threshold and encoding the one or more outgoing code blocks for transmission when communication device is configured to transmit the transport block. The method also includes receiving one or more incoming code blocks that each has a size not greater than the determined segmentation threshold and reconstructing the transport block from the one or more incoming code blocks when communication device is configured to receive the transport block.
Abstract:
A communications apparatus includes a radio module providing a predetermined wireless communications service and communicating with a peer communications apparatus in a predetermined frequency band in compliance with a predetermined protocol. The radio module includes a processor. The processor determines a maximum packet transmission duration, transmits information regarding the maximum packet transmission duration to the peer communications apparatus and negotiates a preferred packet transmission duration with the peer communications apparatus.
