摘要:
A method, arrangement (512) and communication receiver (500) for SNIR estimation of a received signal, by: deriving (512A) an estimation of SNIR of the received signal in accordance with the relation, where E represents mean value and r(t) represents the level of the received signal; and correcting (512B, 512C) the estimation to produce a corrected estimation Z based on the relation Z=α( x ,) where α represents a correction factor. The estimation may be corrected by calculating the correction factor, retrieving the correction factor from a predetermined table (512B) or retrieving the corrected estimation from a predetermined table.

A method for operating bandwidth determination in a multi-bandwidth communication system is described. The method comprises, at a remote unit, receiving a signal ( FIG. 4A ) having a first signal portion at a first predetermined bandwidth ( FIG. 4B ), containing an indication of an operating bandwidth selected from a plurality of bandwidths used for a further signal portion; recovering the indication from the first signal portion at the first predetermined bandwidth; and recovering information in the further signal portion at the operating bandwidth indicated by the indication ( FIG. 4C ). This provides improved efficiency in supporting multi-bandwidth communication system.

A method and arrangement for fair control of resources amongst users with different instantaneous throughputs in a radio communication system such as a UMTS system. Respective indications of users among whom resources are to be allocated are placed in a 'round robin' queue (200) and each user whose indication is at the head of the queue is allocated a number of resource units as a function (300) of: β, a predetermined parameter determining the extent to which a fixed number of resource units should be allocated to the user and the extent to which a fixed volume of data should be transferred from/to the user; ζ, the volume of data that the user is allowed to transfer if β=1; λ, the number of resource units that can be allocated if β=0; and θ, the number of information bits per resource unit that can be transferred to/from the user. This provides the following advantages: the resources can be allocated in the manner chosen by the operator; the function requires very few input parameters, and so is simple to operate.

A method of processing queued data packets in a packet data communication system includes allocating a tier of service for substantially each of a plurality of individual packet data queues and determining a total number of data packets that can use an available communication resource. A proportion of a total number of data packets is allocated to a number of the tiers of service to allow individual packet data queues on a number of tiers to share a communication resource. A communication resource is provided to queued packet data users on a tier-by-tier basis, such that the communication resource is made available to substantially all tiers. Such a technique is considerably easier to implement, it allows better control of resources when throughput rates vary on a per user basis. It is also more applicable when the when the number of allocated resource units per round is small compared to the total number of clients requiring service. Furthermore, the technique reduces the amount of processing required to transfer a number of data packets and is more flexible to changes in the overall number of users served changes.

A mobile communications network and infrastructure equipment are arranged to communicate data to mobile communications devices. The mobile communications network may establish a communications bearer between one of the mobile communications devices and one or more of the infrastructure equipment for communicating data packets for a communications session to the mobile communications device via the communications bearer. The infrastructure equipment is provided with an indication of a type of the data packets communicated via the communications bearer. Communication of the data packets is controlled via the communications bearer in accordance with a relative priority indicated by the type of the data packets communicated via the communications bearer with respect to data packets communicated via other communications bearers.
摘要:
A method for supporting broadcast transmissions and unicast communications in a wireless communication system is described. The method comprises supporting unicast communication in a first mode of operation wherein at least one unicast data transmission unit is encoded and communicated within a time-continuous sub-frame of a first length and a first number of timeslots. The method further comprises supporting broadcast transmission in a second mode of operation, wherein at least one broadcast data transmission unit is encoded communicated over a time period that comprises a discontinuous plurality of the time-continuous sub-frames of the first length.
摘要:
A communication entity is located at one end of a high latency communication link to support Transmission Control Protocol (TCP) communications between a first transceiver entity and a second transceiver entity. The communication entity comprises proxy logic arranged to inspect a received segment and, in response to identifying that the received segment does not contain data, the proxy logic transparently allows a plurality of synchronising segments to pass between the first transceiver entity and the second transceiver entity through the proxy logic such that the proxy logic generates locally at least one acknowledgement message based on the synchronising segments and the inspected received segment.
摘要:
A wireless communication system comprises a plurality of communication networks. A first wireless subscriber communication unit comprises first signal processing logic arranged to support unicast communication in a first communication network. A second wireless subscriber communication unit comprises second signal processing logic arranged to support unicast communication in a second communication network. At least one wireless broadcast communication unit comprises a transmitter and broadcast signal processing logic, operably coupled to the transmitter, and arranged to broadcast communication in a third communication network. The first wireless subscriber communication unit and second wireless subscriber communication unit are capable of simultaneously receiving broadcast communication on the third network together with their respective unicast communication on their respective first or second communication network.
