An aggregation unit includes a transceiver configured to transmit unique signals to a plurality of transmission reception points (TRxPs) for transmission by the plurality of TRxPs and receive uplink signals received by the plurality of TRxPs from a user equipment. The aggregation unit also includes a processor configured to generate a sum of the uplink signals from a subset of the plurality of TRxPs. The subset is determined based on measurements of the unique signals performed by the UE. In some cases, the subset is determined by a baseband unit that receives a measurement report including the measurements performed by the UE. The transceiver is configured to transmit the sum of the uplink signals to the baseband unit over a fronthaul link.

A display system includes a display and a control circuit operable with the display. The display is configured to provide visual output having a presentation orientation. When user input is received, the control circuit can alter the presentation orientation from an initial orientation in response to user input. When non-user events or device events are detected, the control circuit can revert the presentation orientation to the initial orientation in response to the non-user event or device event. Where the presentation orientation has a user input configuration associated therewith, the user input configuration can either be altered with the presentation orientation or retained in an initial disposition.

Embodiments relate to systems and methods for touch-based two-stage text input. An electronic device (), such as a wearable wireless device, can be configured with a two-stage input interface () on a display (). A first stage can include a seek area (), which displays a subset of letters or other symbols to represent the full range of symbolic elements that are available, in a compressed form. The user can identify an intended target range () by touching an area at or around the letter or other symbol of interest. That input triggers the display of a second stage of the interface in a separate selection area (), in which all letters or other symbols in the target range are expanded and displayed. The user can then touch and lift off the letter or other symbol they wish to choose, for example, to insert in a message or application.

A method is provided for dismissing or altering a user-configured alarm upon detection of the user's sleep state. The method includes associating an alarm device with the user's body by securing a wearable device to the user's wrist, placing the device in a pocket, integrating the device into the user's clothing such as a belt, or otherwise placing the device in contact with or adjacent to the user. The device includes one or more sensors for detecting physiological and/or environmental parameters such as heart, respiration, or pulse rate, body movements, eye movements, ambient light, and the like. If the user is asleep, the alarm is actuated in a typical manner. If the user is awake, the alarm is suppressed. If the user is neither asleep nor fully awake, the alarm is adjusted to provide an appropriate level of stimulation.

A RAKE receiver (112) includes a plurality of fingers (122, 124, 126, 128). Each finger includes a demodulator (402) for demodulating a ray of a multipath signal and a time tracking circuit (404) for controlling the time position of the finger in accordance with time position of the ray. A low delay-spread condition is detected and the positions of two adjacent fingers are controlled to prevent convergence of two or more fingers about a common time position. By maintaining finger timing separation, path diversity is exploited by the RAKE receiver even during the low delay-spread condition to improve receiver performance.

A mobile station (104) in a DS-CDMA communication system (100) has receiver diversity. A first antenna (130) receives signals over a communications channel (101) from a base station (102). A second antenna (132) receives signals which are delayed in a delay element (142) by one or more chip times and combined in a summer (148) with signals from the first antenna.
