Abstract: Techniques to mitigate inter-cell interference using joint time and frequency division are described. A frequency band is divided into multiple non-overlapping frequency subbands. The transmission timeline is divided into T in and T out time intervals. Data is exchanged with users in at least one inner region of a cell on the entire frequency band in the T in time intervals. Data is exchanged with users in multiple outer regions of the cell on the multiple frequency subbands in the Tout time intervals. The frequency band may be partitioned into three frequency subbands. Data may then be exchanged with users in first, second and third outer regions on first, second and third frequency subbands, respectively. The regions in which the users are located may be determined based on pilot and/or other measurements.

Abstract: Técnicas para enviar eficientemente informacion sobre el estado del canal mediante la utilizacion de la codificacion diferencial. La codificacion diferencial puede ser llevada a cabo a través de espacio, a través de frecuencia, a través de espacio y frecuencia, a través de espacio, frecuencia y tiempo, o través de alguna otra combinacion de dimensiones. En un diseno, es posible determinar la informacion de estado espacial para multiples canales espaciales sobre multiples subbandas. Los canales espaciales pueden corresponder con diferentes antenas, diferentes vectores de precodificacion etc. Pueden obtenerse los valores de indicador de la calidad del canal (CQI) para los multiples canales espaciales sobre las multiples subbandas. Los valores de CQI pueden codificarse diferencialmente a través de los multiples canales espaciales y las multiples subbandas, para obtener informacion diferencial de CQI. En otro diseno, pueden obtenerse los valores de CQI para multiples canales espaciales sobre las multiples subbandas en multiples intervalos de tiempo, y se los puede codificar espacialmente a través de espacio, frecuencia y tiempo. La informacion diferencial de CQI y la informacion sobre el estado espacial pueden enviarse como retroalimentacion.

Abstract: Systems and methods are provided in a synchronous wireless communication system 100 which enable data to be transmitted between wireless mobile user equipment 110 and base stations 120 without identifying information embedded in the packets 401, thus reducing the transmission overhead. Packets are reordered at base stations 120 based upon a prearranged transmission scheme in which a retransmission for a failed packet is expected in the corresponding HARQ instance of the next group.

Abstract: Un metodo y aparato para determinar la velocidad de datos de una comunicacion de enlace de retorno. Una modalidad incluye transmitir a una velocidad nula en el canal de comunicaciones solo cuando la estacion no esta transmitiendo voz, senalizacion o datos. Una modalidad incluye determinar una velocidad solicitada maxima basandose en la potencia de transmision piloto promedio normalizada y el valor de referencia piloto y determinar el tiempo de la solicitud de velocidad. Una modalidad implica determinar una velocidad de transmision maxima. Una modalidad implica determinar la energia suficiente y un punto establecido de control de potencia.

Abstract: A system and method for a time-scalable priority-based scheduler. A flexible scheduling algorithm utilizing variable scheduling durations enables better system capacity utilization. A rate request (408) is transmitted if data arrives in a buffer, data in the buffer exceeds a buffer depth, and sufficie nt power exists to transmit at the rate requested. A rate assignment (418) responsive to the rate request indicates a scheduled duration and a schedule d rate applicable for the scheduled duration. The scheduled duration is less than or equal to a scheduling period (508). The scheduling period is an interval of time after which a scheduler makes a scheduling decision. The scheduling period is variable and the scheduled duration is variable. The scheduler is preferably applied in a UMTS, CDMA 2000 or HDR-system for rever se link rate scheduling.

Abstract: Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that they different symbol durations coexist.
