Abstract: A cellular communication system is disclosed in which a base station operates a cell which has a supplementary uplink portion (e.g. on a different frequency and/or using a different technology). The base station broadcasts an offset for user equipment (UE) in its coverage area to assist the UE performing cell selection. Specifically, the UE determines; based on measurements for the cell, the offset, and capability of the UE to communicate using the supplementary uplink portion, whether the cell of the base station is an appropriate candidate for cell selection such that: if the UE is capable of communicating using the supplementary uplink portion then the UE performs cell (re)selection based on the offset; and if the UE is not capable of communicating using the supplementary uplink portion then the UE disregards the offset in its cell (re)selection.
Abstract: A communication apparatus including a communication unit that performs a wireless communication, and a control unit that performs a control to cause control information regarding allocation of a resource for a communication with a first apparatus via a first wireless link to be notified to a second apparatus via a second wireless link.
Abstract: The present disclosure provides a method for resetting a medium access control (MAC) layer at user equipment (UE). The method comprises transmitting a system information request message for requesting system information to a network side through a random access procedure; and resetting the MAC layer when the system information is unsuccessfully requested. Embodiments of the present disclosure further provide a corresponding apparatus.

The processor may be further configured to set a send buffer size for a socket associated with the data connection to the calculated send buffer size and control a send rate from the application server device to the UE device for the data connection using the set send buffer size for the socket.
Abstract: A user equipment (105), UE, is configured for use in a wireless communication system (100). The UE (105) acknowledges one or more first commands received from an access node (110) by transmitting, to the access node (110), a first acknowledgment comprising a confirmation field set to a first value. After acknowledging the one or more first commands, the UE (105) acknowledges one or more second commands received from the access node (110) by selectively transmitting or refraining from transmitting, to the access node (110), a second acknowledgement comprising the confirmation field set to a second value depending respectively on whether or not the second value would be different from the first value.
Abstract: Systems and methods for cell selection, reselection and camping are provided. A network node transmits cell broadcast information including a cell reservation indication and a cell reservation exception indication. A wireless device receives cell broadcast information and determines if the cell is reserved for selection. The cell can be selected, and camped on, in accordance with the wireless device being associated with the cell reservation exception indication.
Abstract: Aspects described herein relate to selecting a sidelink control information (SCI) format for indicating a minimum communication range parameter, where the SCI format is a common format defined for requesting both location-based feedback and signal strength-based feedback. SCI indicating a value for the minimum communication range parameter can be generated based on the SCI format. The SCI indicating the value for the minimum communication range parameter can be transmitted to one or more devices.

Abstract: Embodiments of the present invention provide a hotspot scanning method and an electronic device. Whether a condition of initiating a hidden hotspot scanning is met is first determined. If the condition of initiating the hidden hotspot scanning is met, a name of a hidden hotspot is obtained. Then, the hidden hotspot scanning is initiated by using the name of the hidden hotspot. If the condition of initiating the hidden hotspot scanning is not met, the hidden hotspot scanning is not initiated. In this way, whether the condition of initiating the hidden hotspot scanning is met is determined before the hidden hotspot scanning is initiated. This effectively reduces a disclosure probability of the name of the hidden hotspot, thereby achieving a purpose of reducing a security risk in hotspot scanning.
Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE) configured with uplink (UL) spatial multiplexing and UL skipping, the UE receives, from a base station, two UL grants for a Transmission Time Interval (TTI). The UE generates two Medium Access Control (MAC) Protocol Data Units (PDUs) for the TTI, wherein a first MAC PDU of the two MAC PDUs is able to accommodate all available data of the UE. The UE transmits the two MAC PDUs to the base station.
Abstract: In an embodiment, a UE receives a first uplink grant for a first RAT (e.g., 5G NR) and a second uplink grant for a second RAT (e.g., LTE). In one embodiment, the UE schedules an uplink transmission on the first RAT (e.g., by selectively dropping the uplink transmission on particular resource blocks) so as to manage an amount of time that is based on concurrent uplink transmissions on both the first and second RATs are performed. In another embodiment, the UE establishes a first period of time where a BSR transmitted by the UE on the first RAT is adjusted based on scheduling of concurrent uplink multi-RAT transmissions, and a second period of time where no BSR is transmitted by the UE on the first RAT based where concurrent uplink transmissions on both the first and second RATs are not permitted to be scheduled.

Abstract: A method of sounding and feedback with channel quality information and reduced overhead is provided. A receiving station receives a sounding signal transmitted from an access point over multiple sub-channels of a wide channel in a wireless network. The receiving station detects channel quality based on the received sounding signal for each sub-channel. The receiving station then performs channel estimation based on the received sounding signal and thereby determining feedback information. Finally, the receiving station transmits a feedback message to the access point, the feedback message contains NULL feedback information, reduced feedback information, or channel integrity/quality indicators based on the channel quality information for each sub-channel. Based on the feedback message, the access point may repeat the sounding process, narrow the transmission bandwidth, or select only stations who have indicated uncorrupted channel sounding for MU-MMO transmission.
