摘要:
An apparatus that provides control channel signalling to a plurality of user terminals is provided. A definition unit is configured to define at least two allocation table formats. A selection unit is configured to select which allocation table format from the at least two allocation formats is to be used to construct an allocation table. A construction unit is configured to construct an allocation table based at least in part, on the selected allocation table format. A transmitter unit is configured to signal the allocation table to a plurality of user terminals, wherein the selected allocation table format is identified by a unified entry in the allocation table.
摘要:
A number N physical resource blocks PRBs are allocated among M users in a single control signal, in which some PRBs are allocated as localized to only one user UE and some PRBs are allocated as distributed among multiple UEs. The control signal includes M allocation entries, allocation type bits and a user index sequence of N user indexes. Each allocation entry comprises a UE-ID for indicating to which user a corresponding resource is allocated, where an order of the allocation entries indicates a relationship between the user index and the UE-ID. Individual ones of the allocation type bits corresponds to an individual one of the UE index. The allocation type bits indicate whether a corresponding UE is to use localized allocation or distributed allocation.
摘要:
A method for allocation of multi-carrier transmission resources to terminal devices in a network cell of a radio access network, the transmission resources being dividable into symbol-duration time spans in a time domain and into a plurality of sub-carriers in a frequency domain, comprises allocating to a respective terminal device a group of consecutive symbol-duration time spans in the time domain and at least one respective sub-carrier block in the frequency domain, the at least one respective sub-carrier block being formed by a group of respective consecutive sub-carriers. The allocating comprises allocating a respective sub-carrier block and the group of symbol-duration time spans according to one respective allocation type, which is either a localized or a distributed allocation type, the localized allocation type allocating them to one respective terminal device, and the distributed allocation type allocating them to a respective set of terminal devices.
摘要:
A method includes receiving at least one transport block and determining from the at least one transport block a first data unit, wherein a portion but not all of the first, data unit includes a second data unit; determining information corresponding to acknowledgement status of the first data unit; determining, based at least on the information, whether a request should be performed requesting retransmission of the second data unit; and performing the request in response to a determination the request should be performed. Another method includes determining information corresponding to acknowledgement status of a previously transmitted data unit, wherein a portion but not all of the previously transmitted data unit includes a second data unit; determining, based at least on the information, whether retransmission of the second data unit should occur; and performing the retransmission of the second data unit in response to a determination the retransmission should be performed.
摘要:
The specification and drawings present a new method, system, apparatus and software product for varying a length of a radio link ID (RLID) of a user equipment for resource allocation in mobile communication systems. This allows to employ shorter RLID lengths than it is necessary if all user equipments (UEs) in the active mode are uniquely identified simultaneously, thus providing considerable savings in the signaling resource on the physical layer.
摘要:
Methods, computer program products, electronic devices and information blocks are provided that improve both efficiency of transmission and efficiency of segmentation by enabling an intelligent transport block size determination and a flexible segmentation scheme suitable for utilization with retransmission. One exemplary method involves steps of: determining a size of a transport block based on criteria including a size of at least one data block to be transmitted, wherein the transport block size is determined such that the transport block will include at least one segment of a data block of the at least one data block; segmenting the data block of the at least one data block into a plurality of segments including the at least one segment; and populating the transport block with at least the at least one segment.

摘要:
An approach includes detecting failure of an error detection scheme relating to transmission of data units of a transport block. A negative acknowledgement message is generated in response to the detection of the failure. The negative acknowledgement message is forwarded to a radio link controller for discarding one or more of the data units.
摘要:
A device for transmitting a message for reception by another device, comprising: a processor for adding location information to the message, before transmission, wherein the location information identifies an area within which the message is to be hosted for reception by the other device; and a transmitter for transmitting the message, with the location information.
摘要:
A method of allocating resources to cells of a cellular communication system comprising the steps of determining a load in at least one of the cells; selecting a resource reuse pattern from a set of resource reuse patterns based on the determined load; allocating resources in accordance with the selected resource reuse pattern.
