An antenna system and a method for reporting enhanced Reference Signal Receiving Power (eRSRP) of the same are provided. According to an embodiment of the present invention, the method for reporting eRSRP includes: transmitting, by an evolved Node Base (eNB), different reference signals to different transport points being distributed; measuring, by a user equipment (UE), eRSRP of the different transport points; and reporting, by the UE, the measured eRSRP of the different transport points to the eNB. Compared with the prior art, the eNB can obtain channel information of path loss of each transport point, to fundamentally solve the problem of unbalanced power, and can perform other optimization operations based on the information to improve the system throughput and other performance.

Embodiments describe systems, methods, and apparatuses for identifying, based at least in part on an access network discovery and selection function (ANDSF) quality of service (QoS) policy, a preferred access point (AP) of a wireless local area network (WLAN). In some embodiments, the ANDSF QoS policy may be compared to one or more of an air-interface congestion parameter of the AP, and/or a backhaul congestion parameter of the AP.

A cellular telecommunications network architecture is described where certain communication devices are configured to assist the network to improve coverage in regions of poor radio conditions. In certain embodiments, appropriate communication devices are selected to act as a dynamic, out-of-band coverage extensions. The selection of appropriate communication devices is facilitated by assigning the candidate communication devices to clusters where any one cluster has no substantial influence on network performance in any other cluster and then further segmenting each cluster into one or more sub-groups by constraining a maximum transmission power of one or more of the first communication device in each cluster while maintaining one or more network performance metrics. The computational task of searching for an optimal configuration of (candidate) communication devices is thus reduced to a series of simpler computations for a plurality of sub-groups.

Embodiments of the present invention provide a network communications method, apparatus, and system. The method includes: receiving, by a UE, instruction information sent by an RNC in an access network, where the instruction information is used to instruct the UE to: perform uplink and downlink service transmission with a macro base station and perform uplink service transmission with a micro base station in a first area, and/or perform uplink and downlink service transmission with a micro base station and perform downlink service transmission with a macro base station in a second area; and performing, by the UE, service transmission according to the instruction information. The network communications method, apparatus, and system provided by the embodiments of the present invention can minimize uplink interference that is caused by a UE to a micro base station in a first area, and minimize downlink interference that is caused by a macro base station to the micro base station in a second area; further, uplink coverage of the micro base station and downlink coverage of the macro base station may be fully utilized, which improves a throughput rate and reliability of transmission at an edge area of a HetNet.

Methods are described herein for adjusting characteristics of signals used to verify or track the reliability of communication between a remote sensor and a managing device. For example, an exchange rate of signals sent between the remote sensor and managing device may be adjusted to minimize power consumption when the devices are determined to be reliably communicating. In some embodiments, apparatuses and methods herein may further be configured to inform an individual of when a remote sensor approaches a physical boundary, moves out of a communication range, is turned off, becomes damaged, or otherwise has or may become incapable of proper or reliable communication.

In a communication system in which a base station and a terminal communicates, the base station and the terminal communicates efficiently. There is provided the terminal which communicates with the base station, the terminal including: a reception unit 605 which detects a transmission power control (TPC) command in a downlink control information (DCI) format and obtains a power correction value from the TPC command; and a transmission power control unit 6015 which sets transmission power of an uplink signal based on a power correction value obtained from a first TPC command when the terminal is in a first state and sets transmission power of the uplink signal based on a power correction value obtained from a second TPC command when the terminal is in a second state.
摘要:
A set of individually gain adjusted subscriber channels (402, 404, 411, 415) are formed via the use of a set of orthogonal subchannel codes (Wc, Ws, Wf) having a small number of PN spreading chips per orthogonal waveform period. Data to be transmitted via one of the transmit channels is low code rate error correction encoded and sequence repeated before being modulated with one of the subchannel codes, gain adjusted, and summed with data modulated using the other subchannel codes. The resulting summed data (410, 420) is modulated using a user long code and a pseudorandom spreading code (PN code) and upconverted for transmission. The use of the short orthogonal codes provides interference suppression while still allowing extensive error correction coding and repetition for time diversity to overcome the Raleigh fading commonly experienced in terrestrial wireless systems. The set of sub-channel codes may comprise four Walsh codes, each orthogonal to the remaining codes of the set. The use of four sub-channels is preferred as it allows shorter orthogonal codes to be used, however, the use of a greater number of channels and therefore longer codes is acceptable. Preferably, pilot data is transmitted via a first one of the transmit channels and power control data transmitted via a second transmit channel. The length, or number of chips, in each channel code may be different to further reduce the peak-to-average transmit power for higher rate data transmission.
