Abstract:
Apparatus and method for wireless communication in a wireless communication network include receiving a synchronization channel message parameter at a user equipment (UE) from a network entity. The aspects also include transmitting data to the network entity based on the synchronization channel message parameter. Additionally, the aspects include determining whether an assignment of a reverse supplemental (RS) channel to the UE is performed by the network entity. Still further, the aspects include incrementing a counter value when the network entity fails to assign the RS channel. The aspects also include selecting another network entity when the counter value reaches a predetermined threshold. Other aspects, embodiments, and features are also claimed and described.
Abstract:
The disclosure generally relates to dynamic cell reselection to improve device-to-device (D2D) communications where two or more D2D peers are camped onto different cells and one or more D2D peers are located in an overlap region between the cells. For example, in various embodiments, the D2D peers may exchange one or more communication parameters over the (inter-cell) D2D connection and detect that the D2D peers are camped on different base stations (i.e., attached to different cells) based on the exchanged communication parameters. The D2D peer(s) located in the cell overlap region may then obtain measurements on the neighbor cell and a forced cell reselection may be triggered at the appropriate D2D peer(s) located in the cell overlap region such that the D2D peers are camped on the same base station, thereby converting the inter-cell D2D connection into an intra-cell D2D connection that can be more easily maintained.
Abstract:
Apparatus and methods of communicating with multiple subscriptions at a wireless device include tuning away from an active call of a first subscription during a tune away mode to communicate using a second subscription. The apparatus and methods further include performing a first tune away procedure using the second subscription during the tune away mode. Additionally, the apparatus and methods include determining whether one or more additional tune away procedures are to be performed during the tune away mode using the second subscription subsequent to the performing of the first tune away procedure. Moreover, the apparatus and methods include determining to limit performance of the one or more additional tune away procedures and ending the tune away mode and tuning back to using the first subscription for the active call based on the determination to limit the performance of the one or more additional tune away procedures.
Abstract:
A user equipment (UE) performs wireless communication by starting a scan of an absolute radio frequency channel number (ARFCN) configured for performing a narrowband communication. The UE determines, based on a spectral characteristic of a phase of a signal in the ARFCN, whether a cellular communication is deployed in the ARFCN. The UE may then terminate the scan of the ARFCN in response to the spectral characteristic of the phase of the signal in the ARFCN indicating that the cellular communication is deployed in the ARFCN. Alternatively, the UE may proceed with a synchronization signal search on the ARFCN in response to the spectral characteristic of the phase of the signal in the ARFCN indicating that the cellular communication is not deployed in the ARFCN.
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.
