Abstract: A pre-allocation grant schedule for communications between a wireless communication device (UE device) and a base station may be conducted according to requests made by the UE device. The UE device may provide information to a base station, requesting the base station to end a previous pre-allocation schedule and/or to start a new pre-allocation schedule. A request for stopping a previous pre-allocation schedule and starting a new pre-allocation schedule may be transmitted at the same time or in subsequent frames, respectively, depending on whether transition is from talk to non-talk mode or non-talk to talk mode. The base station may determine a pre-allocation schedule using the information received from the UE device, and may begin communicating uplink grants to the UE device according to the pre-allocation schedule requested by the UE device. The UE device may in turn may communicate with the base station according to the received uplink grants.

Abstract translation: 可以根据UE设备发出的请求，对无线通信设备（UE设备）和基站之间的通信进行预分配准备时间表。 UE设备可以向基站提供信息，请求基站终止先前的预分配调度和/或开始新的预分配调度。 可以分别在同一时间或后续帧中发送停止先前的预分配调度和开始新的预分配调度的请求，这取决于转换是从通话模式还是非通话模式或非谈话模式 模式。 基站可以使用从UE设备接收的信息来确定预分配调度，并且可以根据UE设备请求的预分配调度开始向UE设备传送上行链路授权。 UE设备又可以根据所接收的上行链路授权与基站进行通信。

Abstract: A device, system, and method perform an adaptive link adaptation. The method, at a user equipment (UE) connected to a Long Term Evolution (LTE) network via an evolved Node B (eNB), includes determining a type of wireless traffic being utilized by the UE based upon at least one application executed on the UE, the wireless traffic being one of a data only, a voice only, or a combination thereof. The method includes determining a block error rate (BLER) target value to be used in a channel state feedback operation associated with a link adaptation operation for a connection between the UE and the eNB.

Abstract: Systems and methods for reducing collisions of transmission data for a first subscriber (e.g., a voice subscriber) with transmission data for a second subscriber (e.g., a data subscriber) at a dual sim dual active (DSDA) user equipment (UE) are described herein. A DSDA UE may be configured to implement a modified skipUplinkTxDynamic feature that avoids collisions by buffering transmission data of the data subscriber and sending a (later) scheduling request (SR) for a grant for that data. A DSDA UE may regulate data subscriber transmissions to avoid a transmission duration for the voice subscriber. A DSDA UE may reduce certain transmissions for a voice subscriber (subject to a block error rate (BLER) threshold for the voice subscriber) to lower the probability of collision. A DSDA UE may operate a data subscriber and a voice subscriber in the same cell to avoid collisions due to RF tuning and/or relative slot overlap.

Abstract: Described herein are apparatuses, systems and methods for adaptive downlink scheduling and link adaptation. The methods including, at a base station connected to a user equipment (“UE”), determining an initial modulation and coding scheme (“MCS”) for a plurality of subframes to be transmitted to the UE, wherein each MCS relates to a coding rate value for the subframes, determining an MCS pattern for the plurality of subframes based on the initial MCS, wherein an MCS for one of the subframes has a higher coding rate value than the initial MCS, and transmitting the plurality of subframes to the UE according to the MCS pattern.
