Described is a method for the mapping of reference signals. The method includes generating a reference signal sequence for two or more cells, where each cell of the two or more cells has a cell bandwidth. The method also includes determining an offset for the reference signal sequence based at least in part on the cell bandwidth of each cell. Mapping the reference signal sequence to resource elements of physical resource blocks for the cells based at least in part on the offset is included in the method. Apparatus and computer readable media are also disclosed.

Systems and methods for enabling the dynamic allocation of certain subframes as downlink or uplink resources in a time division duplexed over the air communications system. A base station or eNB may allocate certain subframes within a repeating radio frame of a TDD configuration as either DL or UL subframes for communicating to user equipment or UE devices to increase efficient use of system resources based on the data to be transmitted. Methods for determining the capabilities of a selected UE and based on the determining step, dynamically allocating certain subframes are disclosed. The methods and systems are compatible with user equipment that does not support the dynamic allocation of subframes.

Dynamic allocation of subframe scheduling for time divison duplex operation in a packet-based wireless communication system

An allocation of downlink resources is received, which are monitored on l layers for data. A resource-specific bit (ACK/NACK) is generated for each of those resources. From a pattern of those resources is selected an algorithm from among a first algorithm that bundles them in a first mode and a second algorithm that bundles them in a second mode. The selected algorithm is used on the generated resource-specific bits that correspond to the downlink resources, bundled according to the selected mode, to generate l reply bits which are then transmitted. At the network side a NACK reply bit is received, based on a pattern of the allocated downlink resources, a first algorithm that bundles them in a first mode or a second algorithm that bundles them in a second mode is selected. A bundling window and layer combination are determined from the selected algorithm, which gives the resource for retransmitting the NACK'd data.

An apparatus and a method are provided. The provided solution includes a controller configured to determine a transmission mode for user equipment, the transmission mode including non-codebook precoding with fixed precoding granularity; and to control a transceiver to transmit information on the selected transmission mode to the user equipment.

Apparatus and method for non-codebook based precoding

According to an embodiment a user equipment UE transmits uplink control signals using one or more chunks of uplink frequency spectrum that contain a simultaneous uplink shared channel; and for the case where there is no simultaneous uplink shared channel available, the UE transmits uplink control signals using only a single chunk of uplink frequency spectrum. In various embodiments the control signals are ACK/NACK control signals transmitted on an uplink control channel, the uplink shared channel comprises a chunk-specific uplink control channel, and each chunk comprises a component carrier of a LTE-A system. Downlink assignment index bits may be included in a downlink grant to the UE which indicates how many chunks in total are allocated in a current downlink subframe. The UE can also use ACK/NACK control signal bundling over chunks in addition to either or both of chunk-specific ACK/NACK control signals or ACK/NAK control signal multiplexing.

Optimized uplink control signaling for extended bandwidth

A method for controlling channel signaling between a UE and a wireless network access node is described. The method includes determining whether an examined sub-frame of a plurality of sub-frames in a first resource region is unused. The index of the examined sub-frame is a last index of the plurality of sub-frames allocated for use in a first channel. The plurality of sub-frames is organized in a reverse indexing manner such that a last indexed sub-frame is adjacent to a second resource region. The second resource region is allocated to a second channel. In response to determining that the examined sub-frame is unused, the examined sub-frame is re-allocated for temporary use in the second channel. The method also includes providing an indication of the allocation. Apparatus and computer readable media are also described.

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.
