Abstract: Un método de un dispositivo inalámbrico comprende determinar un ancho de banda para el monitoreo de una señal de control de enlace descendente, determinar un conjunto de posibles formatos de indicador de control de enlace descendente, DCI, que son compatibles con el ancho de banda determinado, recibir a transmisión de un nodo de red, buscar información de control en la transmisión mediante decodificación usando al menos uno de los formatos DCI del conjunto y, si la decodificación de la información de control es satisfactoria, ejecutar al menos una tarea asociada con dicha información. Un método de un nodo de red comprende configurar un ancho de banda de enlace descendente que debe emplearse en las transmisiones de enlace descendente, determinar un formato DCI en base al ancho de banda de enlace descendente y transmitir información de control usando un DCI con el formato DCI determinado. Se divulgan un dispositivo inalámbrico y un nodo de red dispuestos, respectivamente, para ejecutar los métodos e implementar los programas de computación que ponen en práctica los métodos.

Abstract: There are provided mechanisms for monitoring search spaces. A first method performed by a wireless device comprises receiving an OFDM symbol in a downlink slot. At least part of the OFDM symbol is included in a device-specific search space and in a common search space. The first method comprises monitoring the device-specific search space for at least one device- specific reference signal (RS) and monitoring the common search space for at least one non- device-specific RS. In a second method, a radio access network node transmits an OFDM symbol included in a device-specific search space and in a common search space. The device- specific search space contains a device-specific RS, or the non-device specific search space contains a non-device-specific RS, or both of these apply.

El metodo ejemplificativo ademas incluye, en el mismo dispositivo inalambrico, recibir en una primera subtrama de enlace descendente, una primera transmision de multiplexacion por division de frecuencia ortogonal (OFDM) con formato acorde con una primera numerologia y recibir, en una segunda subtrama de enlace descendente, una segunda transmision OFDM con formato acorde con una segunda numerologia, que difiere de la primera, donde la primera numerologia tiene un primer espaciado de subportadoras y la segunda numerologia tiene un segundo espaciado de subportadoras, y el primer espaciado difiere del segundo. Tambien se divulgan variantes de este metodo, correspondientes aparatos y correspondientes metodos y aparatos del lado de la red.

Abstract: Systems and methods are provided for allocation of acknowledgement resources. In an embodiment, a method of transmitting control information to a communication network may be implemented in a wireless device. The method may include being configured with at least two physical uplink control channel (PUCCH) opportunities, each of the at least two PUCCH opportunities identifying uplink resources to be used for transmitting control information to the communication network. The method may further include receiving an acknowledgement resource indication (ARI) indicating one of the configured at least two PUCCH opportunities to be used for transmitting control information associated with the DL transmission.

Abstract: Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first downlink subframe, a first Orthogonal Frequency-Division Multiplexing, OFDM, transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology, where the first numerology has a first subcarrier spacing and the second numerology has a second subcarrier spacing, the first subcarrier spacing differing from the second subcarrier spacing. The example method further includes, in the same wireless device, receiving and processing first Layer 2 data on a first physical data channel and receiving and processing second Layer 2 data on a second physical data channel, wherein the receiving and processing of the first Layer 2 data comprises the use of soft HARQ combining and wherein the receiving and processing of the second Layer 2 data comprises no soft HARQ combining. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

Abstract: Methods and apparatuses disclosed herein enable the use of Demodulation Reference Signal, DMRS, sequences that are numbered relative to an overall system bandwidth (30), while simultaneously enabling wireless communication devices (12) to determine the DRMS sequence elements mapped to their scheduled bandwidths (36) within the system bandwidth (30). Advantageously, the wireless communication devices (12) need not know the system bandwidth (30), or even be aware of where their scheduled bandwidths (36) reside within the system bandwidth (30).
