A system, method and computer-readable medium for allocating multiple subscriptions to a single mobile terminal thereby allowing concurrent termination of multiple calls at the mobile terminal are provided. A mobile terminal adapted to terminate multiple concurrent calls is described. In one implementation, a network need not have any configuration data regarding the multi-line capabilities of the mobile terminal. In other implementations, network-centric mechanisms are provided for allowing multiple concurrent calls to be terminated by a mobile terminal. Multiple concurrent calls may be terminated at a mobile terminal on separate carrier frequencies or alternatively may be terminated on a common carrier frequency.

A method of initiating handover of a wireless device includes determining one or more of a low battery condition, a low power headroom, and a high buffer status of a wireless device. The wireless device can be attached to a first access node deploying multiple radio access technologies over a first coverage area. The method further includes identifying a second access node deploying a single radio access technology over a second coverage area encompassing a location of the wireless device, and initiating handover of the wireless device from the first access node to the second access node based at least in part on the one or more of the low battery condition, low power headroom, and high buffer status of the wireless device. Systems and devices relate to initiating handover of a wireless device.

A signal processing device includes: a transmission path estimator that estimates a first transmission path characteristic of a transmission signal using a vertical signal out of vertical and horizontal signals resulting from being received by a vertical polarization antenna and a horizontal polarization antenna; a transmission path estimator that estimates a second transmission path characteristic of the transmission signal using the horizontal signal; a weight calculator that calculates a first weight for the vertical signal and a second weight for the horizontal signal, using the first transmission path characteristic and the second transmission path characteristic; and a weighting applier that applies weighted summation to the vertical signal and the horizontal signal using the first weight and the second weight.

A wireless audio output device includes a plurality of audio output units, first and second audio output units among the audio output units being set as first and second roles, respectively. The first role is to establish a multicast link with a source device, to receive one or more media packets from the source device on the multicast link, and to perform bidirectional communication with the source device. The second role is to join the multicast link, to receive the one or more media packets from the source device on the multicast link, to perform unidirectional communication with the source device, and to perform unidirectional and/or bidirectional communication with the first role. An extended packet time slot is divided and each of the first role and the second role transmits or receives one or more extended packets during the extended packet time slot.

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques that may help mitigate service loss for a UE (e.g., in DSDA mode) due to temperature rise. According to certain aspects, a UE detects, while operating in a multi subscriber identity module (SIM) mode with at least a first subscriber (SUB) and a second subscriber (SUB) active on a first radio access technology (RAT), that the UE has reached a first temperature threshold less than a second temperature threshold at which the UE limits service in the first RAT and greater than a third temperature threshold associated with a temperature mitigation level. The UE then takes action to move the first SUB to a second RAT in response to the detecting.

Systems and methods for User Equipment (UE) operation in presence of Clear Channel Assessment (CCA) are provided. In some embodiments, a method performed by a wireless device for cell selection accounting for requirements includes: determining a measurement period in a serving cell for the cell selection or cell re-selection (T1), wherein the measurement period is determined based on a number of consecutive Discontinuous Reception (DRX) cycles; determining a number of measurement occasions configured with a Discovery Reference Signal (DRS) in the serving cell during T1; determining availability of the DRS at the measurement occasions; and performing measurement based on availability of the DRS at the measurement occasions during T1. In this way, a wireless device may operate in NR RRC_IDLE/RRC_INACTIVE in the presence of CCA, e.g., Listen-Before-Talk (LBT).
