Abstract: Currently, the MIMO MAC-CEs have been designed to support only one component carrier. Aspects described herein provide MAC-CEs and RRC signaling, which may facilitate efficient spatial and beam change indications for multiple component carriers. A UE may be configured to receive a configuration for each of a plurality of carriers. The UE may be configured to receive control information in a MAC-CE. The control information may comprise at least one of a TCI state, an CSI-RS resource configuration, or an SRS resource configuration. The UE may be further configured to determine whether the control information applies to multiple carriers from among the plurality of carriers. The UE may be configured to apply the control information to at least one of the plurality of carriers based on a determination of whether the control information applies to multiple carriers from among the plurality of carriers.

Abstract: Methods, systems, and devices for wireless communication are described in relation to a Multiple Subscriber Identify Module (MSIM) user equipment (UE). The UE associated with multiple network subscriptions may determine a first timing of a first set of paging occasions associated with a first network subscription of the multiple network subscriptions, wherein the first network subscription is associated with a first network; determine a second timing of a second set of paging occasions associated with a second network subscription of the multiple network subscriptions, wherein the second network subscription is associated with a second network; compare the first timing and the second timing; detect a paging time adjustment condition based on the comparing; and transmit, based on detecting the paging time adjustment condition, a paging frame offset adjustment request to the first network, the second network or both.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for reducing resource contention between two or more RATs supported by a User Equipment (UE). The UE may determine a first level of contention between Radio Frequency (RF) resources to be used by two or more Radio Access Technologies (RATs) supported by the UE over a given period of time for performing at least one type of receive activity, based at least on assigned Discontinuous Reception (DRX) cycles for the RATs. The UE may decide to initiate an update of a DRX cycle for at least one of the RATs to reduce the contention, at least if the determined first level is greater than a given threshold level of the contention over the given period of time.

Abstract: A method of operating a wireless device includes determining to operate the wireless device in a discontinuous reception (DRX) mode of operation such that a receiver of the wireless device is expected to operate in a low-power state during a scheduled low-power period of time and the receiver is expected to operate in an active-power state during a scheduled active-power period of time. The wireless device schedules a measurement of a positioning signal using the receiver. The measurement is scheduled to occur during a scheduled measurement period of time. The scheduled measurement period of time at least partially overlaps with at least one of the scheduled low-power period of time or the scheduled active-power period of time. The wireless device operates the wireless device in the DRX mode of operation after scheduling the measurement and before a start of the scheduled measurement period of time.

Abstract: A method for improving device-to-device (D2D) communication in an LTE-Direct communication system includes exchanging communication information between a first user equipment (UE) and a second UE over an LTE-Direct connection with a first network resource of a first set of network resources allocated to the first and second UEs by a base station for the LTE-Direct connection. The method also includes determining, by the first UE, whether a first link quality of the LTE-Direct connection with the first network resource is below a link quality threshold. If so, the LTE-Direct connection is shifted to another network resource of the first set of network resources until an LTE-Direct connection is established that has a link quality that is equal to or greater than the link quality threshold.

Abstract: Methods and apparatuses are presented for acquiring a wireless system by a multi-subscriber identity module (SIM) user equipment (UE). For example, an example method for acquiring a wireless system is presented that includes conducting, by a first subscription corresponding to a first SIM of the UE, a call using a shared radio resource of the UE. In addition, the example method may include predicting, upon completion of the call, a pilot timing error and a frequency error associated with a pilot signal of a network associated with a second subscription corresponding to a second SIM of the UE. In addition, the example method may include attempting to acquire the pilot signal based on the pilot timing error and the frequency error. As such, the example method may allow the multi-SIM UE to more quickly acquire a wireless system relative to legacy methods. Other aspects, embodiments, and features are also claimed and described.
