摘要： Efficient encoding techniques are described for encoding resource allocation data to be signalled to a number of user devices in a communication system. In one encoding technique, a resource allocation bit pattern is transmitted to all the users together with a resource ID for each user. Each user then identifies its allocated sub-carriers using the received allocation bit pattern and the received resource ID. In another encoding technique, a code tree is used to generate a value representing the sub-carrier allocation. The user device then uses the code tree to determine the sub-carrier allocation from the signalled value.

摘要： FREQUENCY HOPPING TECHNIQUE FOR EUTRA UPLINK 5 A communications system (1) is described in which user devices (3-0, 3-1, and 3-2) communicate with an associated base station (5-1). The user devices employ frequency hopping techniques to provide frequency diversity in their communications with the base station. Methods and techniques are described for reducing collisions between the communications from the different user devices and for the efficient signalling of data 10 defining the frequency hopping sequence to use. The embodiments are particularly suitable for use in the uplink of the E-UTRA communications scheme.

摘要： SIGNALLING OF RESOURCE ALLOCATIONS IN A COMMUNICATION Abstract Disclosed is a method of signalling resource allocation data in a communication system which uses a plurality of sub-carriers arranged in a sequence of chunks. The method comprises: receiving an allocation of said sub-carriers for each of a plurality of user devices; processing the received allocations to determine, for each user device, data identifying a start chunk and an end chunk within said sequence of chunks, which depend upon the sub-carriers allocated to the user device wherein the data identifying the start chunk and the end chunk comprises a start chunk number and a number of consecutive chunks between the start chunk and the end chunk; generating respective resource allocation data for each of said user devices using said data identifying the corresponding start chunk and end chunk determined by said processing step, wherein said resource allocation data comprises a unique value representing the corresponding start chunk number and the number of consecutive chunks between the corresponding start chunk and the corresponding end chunk; and signalling said respective resource allocation data, comprising said unique value, to each of said plurality of user devices. 6191226-1

摘要： A mobile communication system in which a mobile communication device can register with a home base station when in range of the home base station. The home base station may be an open access mode, a closed access mode or a hybrid access mode home base station. The home base station sends a gateway device information about its access mode so that unnecessary access control is avoided. This information may be signaled to the gateway device by the presence or absence of an optional element of a registration request or by the presence or absence of entries within a mandatory element within the registration request.

摘要： A mobile telecommunications system is described in which a base station allocates each mobile telephone a plurality of physical resource blocks by signalling data identifying a virtual resource block. The virtual resource block is mapped onto the plurality of physical resource blocks using stored mapping data. The mapping data is such that the mapped physical resource blocks are spaced over the operating bandwidth and all belong to the same resource block group subset. Application in OFDMA for the allocation of distributed virtual resource block (DVRB) to UEs and in particular to the mapping between the physical resource blocks and the DVRB.

摘要： In an Orthogonal Frequency Division Multiplexing (OFDM) mobile telecommunications uplink from users (3, fig. 1) to base station (5), subcarriers are dynamically allocated (33, fig. 2) in contiguous resource blocks RB signalled by a starting block, O, and P consecutive RB's, where P is a product of 2, 3 and 5 which can be written in an index table (p. 10). An encoder module 35 maps the O and P allocation values using either the index table itself or an integer based on indexP, O and the system bandwidth (see equations on p.16). The latter method provides a one bit saving compared to the former for a bandwidth of 20 MHz, and requires no lookup table to be stored in the mobile units or base station.
