摘要:
Apparatus and method for communication are provided. The apparatus includes a controller for controlling the transmission and reception of data on one or more carriers utilizing Time Division Duplexing and frames including sub frames, where multiple carriers utilized by different apparatuses are synchronized with each other and a predetermined number of sub frames of each frame are reserved for predetermined transmission directions and a scheduler for allocating the rest of the sub frames carrier specifically either in downlink or uplink direction.
摘要:
A method and apparatus for controlling retransmissions in multipoint reception is disclosed. In the method it is determined that additional information is needed for decoding of at least one received information block. A procedure is selected for obtaining the additional information from a plurality of options to proceed based on information about predicted result of at least one of the options. In accordance with an aspect an indication of one of a positive according knowledgement of the information block, a negative acknowledgement of the information block and suspension of retransmission of the information block is generated and communicated on a retransmission control channel.

It is disclosed a method (and related apparatus) including allocating a first bandwidth portion of a first transmission channel of a first communication network cell based on a restriction imposed by a second bandwidth portion, at least partially overlapping the first bandwidth portion, of a second transmission channel of at least one second communication network cell neighboring the first communication network cell; and a method (and related apparatus) including transmitting signals relating to at least one of control and data in an allocated first bandwidth portion of the first transmission channel of the first communication network cell allocated based on the restriction imposed by the second bandwidth portion, at least partially overlapping the first bandwidth portion, of the second transmission channel of the at least one second communication network cell neighboring the first communication network cell.
摘要:
Resources for reference signalling on at least one component carrier of a plurality of aggregated component carriers can be determined by a station. Information indicative the at least one component carrier and the associated resources is then communicated to another station for configuration of the other station. A trigger is then sent for reference signalling, and in response to the trigger, at least one reference signal is sent from the other station using the indicated at least one component carrier and resources.

Apparatus including at least one processor and at least one memory including computer program code the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: determining at least one control symbol and at least one channel from a channel set for an at least one control symbol representing the at least one control signal for at least one output port; and determining at least one further control symbol and at least one further channel from the channel set for the at least one further control symbol for at least one further output port, wherein the at least one further control symbol and the at least one further channel is dependent on the at least one control symbol and the at least one channel.
摘要:
There is proposed a mechanism by means of which resources for a data transmission between a user equipment and a base transceiver station are set. For this purpose, a resource dedicated to the user equipment (like an SR resource) is combined with at least one contention based resource allocated to a contention based transmission by the user equipment (like a CB-PUSCH resource). The at least one contention based resource to be combined is selected by executing a mapping according to a predetermined rule and based on an information indicating a specific resource element dedicated to the user equipment to at least one set of available contention based resources, and by determining an information identifying at least one resource element of the at least one contention based resource.
摘要:
An apparatus includes at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to: reserve at least an equal number of modulation symbols for uplink control information symbols in each physical uplink shared channel transport block; create at least one layer-specific replica of the uplink control information symbols to be placed in some of reserved resources of the physical uplink shared channel transport blocks; and scramble uplink control information symbols including the symbols of the at least one layer-specific replica in a layer-specific manner for multiplexing the uplink control information with physical uplink shared channel data.
