摘要:
A method of transmitting uplink control signals/status bits from a user equipment, said user equipment having multiple transmit antennae, and said control signals correspond to a plurality of previous downlink transmissions, wherein said control signals are transmitted over a plurality of PUCCH resources and over said multiple antennae, and transmitted during a single uplink sub-frame. Use of multiple PUCCH resources and multiple antennae allow greater spatial diversity.

In order to facilitate sending of different kinds of channel feedback information, a periodic information transmission in a shared uplink channel is configured, PUSCH, and required resources are allocated for the transmission.
摘要:
A method, apparatus, and computer program for controlling allocation of control message fields in uplink transmission in a cellular telecommunication system are presented. Uplink control message fields are allocated to the resources of a physical uplink shared traffic channel according to an uplink transmission scheme selected for a user terminal. The control message fields are allocated so that transmission performance of the control messages is optimized for the selected uplink transmission scheme.
摘要:
A method for performing uplink signaling and data transmission between a terminal device and a network element is described. The method includes applying, during a transmission, at least one of TDM and FDM between a SRS, a control channel, a DRS and a data channel. Clustered sub carrier mapping is applied for the SRS and the control channel. The SRS is transmitted so as to function as a DRS for the control channel. The control channel and the data channel are transmitted during a same sub-frame. The method also includes receiving the SRS and receiving the control channel and the data channel during a same sub-frame. Control information and data are extracted from the control channel and the data channel. The SRS is used as a DRS for the control channel is included in the method. Apparatus and computer readable media are also described.

Embodiments of the present invention provide methods, systems and apparatuses for optimizing downlink path loss (PL) measurements in time division duplex (TDD) systems enabling fast power control targeting to decrease fading margin. In one embodiment, a method of power control in a long term evolution time division duplex (TDD) system is provided. The method includes controlling a length of a path loss measurement filter based on an allocation type. A width and frequency position of the path loss measurement filter is made dependent on the allocation type.
摘要:
Apparatus and method for communication are provided. An apparatus includes a receiver configured to receive control and data signal; a transmitter configured to transmit control information on an uplink channel wherein a number of uplink control channel indexes corresponding to the number of control channel elements as on the downlink control channel is available, the transmission requiring more than one uplink channel index; and a controller. If one control channel index is available, the controller is configured to control the transmission of control information to utilise the uplink control channel index and control the transmission of control information related to a second control channel index based on a separate channel or adjusting transmission properties when transmitting the control information.
摘要:
An apparatus for providing reduced feedback delay may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured, with the processor, to cause the apparatus to perform at least selecting a frame format to be applied for configuring transmission and reception of data. The frame format may be selected from options including a downlink only format, an uplink only format and a downlink and uplink format. The apparatus may be further configured for communicating the frame format to a transceiver to enable configuration of the transceiver for transmission and reception of data according to the frame format selected. A corresponding method and computer program product are also provided.
摘要:
An apparatus and a method is described, by which a component carrier configuration, re-configuration, activation or de-activation is performed. In particular, a signaling format used for acknowledgment/negative acknowledgement messages on an uplink control channel is detected, and a codebook size of the acknowledgment/negative acknowledgement messages is decided based on the detected signaling format.
摘要:
A method is disclosed for scheduling packet data in a communications system. The method includes configuring, in a network apparatus, semi-persistent transmission resources to a user equipment via higher layer signalling, wherein the configuring step includes pre-allocating a data transmission resource and assigning a scheduling request resource to the user equipment. A confirmation message is transmitted to the user equipment from the network apparatus, wherein the confirmation message informs the user equipment that the user equipment is able to start transmitting data on a physical uplink shared channel PUSCH to the network apparatus by using the pre-allocated data transmission resource and a pre-configured transmission format, wherein the pre-allocated data transmission resource is linked to the corresponding confirmation message, the corresponding confirmation message being linked to the corresponding semi-persistently assigned scheduling request resource.
