Abstract: Methods, systems, and devices for wireless communications are described. In some cases, devices such as band limited (BL) or coverage enhancement (CE) user equipment (UE) having limited transmitting and receiving capability may operate using a subset of a system bandwidth of a carrier (e.g., narrowbands). To support frequency hopping or frequency diversity in transmissions, for example, such devices may utilize retuning when a resource allocation moves from a first narrowband to a second narrowband. Retuning, however, may create challenges when transmitting and receiving capability is limited. Aspects of this disclosure may support a flexible starting physical resource block (PRB) for indicating new resource allocations for BL or CE UEs. In some aspects, a UE is disclosed which may retune between consecutive transmission time intervals (TTIs) or subframes, for example, from a first tuning band to a second tuning band (e.g., a newly defined retuning narrowband).

Abstract: programação de rendimento aperfeiçoado em comunicação tipo máquina aperfeiçoada. métodos, sistemas e dispositivos para comunicações sem fio são descritos. um quadro, caso de programação, período de programação, etc., podem incluir: um conjunto de subquadros de downlink e um conjunto de subquadros de uplink. pelo menos uma mensagem de controle transmitida em um subquadro de downlink pode programar um conjunto de mensagens de dados nos subquadros de downlink do quadro. o subquadro de downlink também pode incluir mensagens de dados programadas por uma mensagem de controle de um quadro anterior. adicionalmente, as temporizações de retorno para as mensagens de dados do quadro podem ser determinadas com base nas mensagens de controle correspondentes (por exemplo, a partir do quadro atual e do quadro anterior). as respostas de retorno correspondentes às mensagens de dados podem ser transmitidas de uma forma agrupada no conjunto de subquadros de uplink. utilizando-se essa técnica de programação de quadro cruzado, os recursos de um quadro podem ser utilizados de forma eficiente.

Abstract: Methods, systems, and devices for wireless communications are described. A frame, scheduling instance, scheduling period etc. may include a set of downlink subframes and a set of uplink subframes. At least one control message transmitted in a downlink subframe may schedule a set of data messages in the downlink subframes of the frame. The downlink subframe may also include data messages scheduled by a control message of a previous frame. Further, feedback timings for data messages of the frame may be determined based on the corresponding control messages (e.g., from the current frame and the previous frame). Feedback responses corresponding to the data messages may be transmitted in a bundled manner in the set of uplink subframes. Using this cross-frame scheduling technique, the resources of a frame may be efficiently utilized.

Abstract: Techniques for estimating signal quality in a communication system are described. Scaled errors are obtained for inphase (I) and quadrature (Q) components of detected symbols. The scaled errors are determined based on a first function having higher resolution for small errors than large errors between the detected symbols and nearest modulation symbols. The first function may be a square root function or some other function that can provide good resolution for both low and high SNRs. The scaled errors for the I and Q components are combined to obtain combined scaled errors, which are averaged to obtain an average scaled error. A signal quality estimate is then determined based on the average scaled error and in accordance with a second function having non-linearity to compensate for the first function.
