摘要： Distributed antenna systems (DASs) can include a plurality of spatially separated remote antenna units. According to at least one example, a first group of remote antenna units can simulcast downlink transmissions on a first carrier with a particular sector identity (ID). A second group of remote antenna units, including at least one different remote antenna unit from the first group, can simulcast downlink transmissions on a second carrier with the same sector ID. According to at least one other example, two or more remote antenna units which include respective coverage areas that are non-adjacent to one another can be employed to simulcast downlink transmissions.

摘要： Embodiments disclosed herein relate to carrier allocation and management in multi-carrier communication systems. In some embodiments, the number of carriers assigned to an access terminal on a forward link may be determined by an access network, and the number of carriers assigned to the access terminal on a reverse link may be based on a cooperative process between the access terminal and the access network. In other embodiments, the number of carriers assigned to the access terminal on the reverse link may also be determined by the access network, e.g., in relation to the scheduling information received from the access terminal.

摘要： In a wireless communications system, a serving base station performs outer and closed power control for an overhead channel and a traffic channel for data, either of which can carry an acknowledgement (Ack) channel and Channel Quality Indicator (CQI) channel on an uplink from User Equipment (UE). In an exemplary aspect, data packet communication is implemented in 3GPP LTE Rel. 8 wherein the uplink has a Single Carrier Frequency Division Multiplex (SC-FDM) uplink waveform. The UE performs open loop power control by a determining transmit power spectral density value by using received energy per symbol for a reference signal.

摘要： Carrier management in a wireless communication device assigned a set of two or more carriers by a wireless communication network is disclosed. In one aspect, a method of carrier management includes transmitting data over the wireless communication network on one or more carriers forming a subset of active carriers from the set of carriers assigned to the wireless communication device. A first performance metric is determined indicative of operating conditions across the set of carriers assigned to the wireless communication device. A desired number of carriers on which to transmit data based on the first performance metric is determined. The desired number of carriers on which to transmit data is compared with the number of carriers in the subset of active carriers. The subset of active carriers is dynamically adjusted based on the comparison and subsequent data is transmitted over the wireless communication network using the adjusted subset of active carriers.

摘要： Some implementations provide a method for prioritizing reverse link packets so that particular reverse link packets are transmitted with a reduced latency in order to improve spectral efficiency of the forward link. The method also optionally includes weighting packets according to their determined lengths, and transmitting packets based on the determined weights. In one implementation, the method includes sorting packets at least according to one of size, type and nature of the data in the packets. Accordingly, sorting of the packets includes at least one of determining the size and the type of each packet. In one implementation, sorting the packets includes deep-packet inspection to determine a respective priority value for each packet.
