METHOD AND APPARATUS FOR DETERMINING TRANSPORT BLOCK SIZE
A method for determining a transport block size includes: determining an overhead of a sidelink data channel PSSCH demodulation reference signal (DMRS) in a physical resource block (PRB) of a first time-frequency resource, where the first time-frequency resource includes a first time unit in time domain; and determining, based on the overhead of the PSSCH DMRS, a number of resource elements (REs) on the first time-frequency resource that are for data transmission, where the number of REs for data transmission is for determining a transport block size (TBS) of the sidelink data channel PSSCH. The method provides a combined gain of a plurality of transmissions of a same transport block, and supports DMRS configurations of different quantities of DMRS symbols in initial transmission and retransmission of one transport block.

An apparatus for use by a communication network control element or function configured to conduct a radio resource management, the apparatus being configured to cause the apparatus at least: to acquire input parameters; to process the input parameters by using a first-stage procedure for maximizing a weighted sum-rate for a fixed subcarrier allocation for all subcarriers, and a second-stage procedure for determining a power allocation for a single subcarrier under consideration of specified multiplexing and interference cancellation constraints wherein a processing result output from the first-stage procedure is input into the second-stage procedure, and a processing result output from the second-stage procedure is returned to the first-stage procedure; and to output, on the basis of results of the processing in the first-stage procedure and the second-stage procedure, a power setting for at least one subcarrier.
Transmitter, receiver, transmission method, and reception method
Provided is a transmitter which improves the flexibility of SRS resource allocation without increasing the amount of signaling for notifying the cyclic shift amount. In the transmitter, with regard to each basic shift amount candidate group having a basic shift amount from 0 to N−1, a transmission control unit (206) specifies the actual shift amount imparted to a cyclic shift sequence used in scrambling a reference signal transmitted from each antenna port, said specification being performed based on a table in which cyclic shift amount candidates correspond to each antenna port, and based on setting information transmitted from a base station (100). With regard to basic shift amount candidates for shift amount X, the table differentiates between an offset pattern comprising offset values for cyclic shift amount candidates corresponding to each antenna port and an offset pattern corresponding to basic shift amount candidates of X+N/2.

A method of OFDMA subcarrier allocation for stations in a wireless network includes determining a total downlink buffered traffic load for downlink traffic from a gateway device to the stations, and receiving a total uplink buffered traffic load for uplink traffic from the stations to the gateway device. The method further includes determining a first ratio of total downlink buffered traffic load for each station in relation to total downlink buffered traffic load for all stations, determining a second ratio of total uplink buffered traffic load for each station in relation to total uplink buffered traffic load for all stations, performing OFDMA subcarrier allocation for the downlink traffic by assigning available channel bandwidth proportional to the first ratio for each station, and performing OFDMA subcarrier allocation for the uplink traffic by assigning available channel bandwidth proportional to the second ratio for each station.

Method and apparatus for low latency transmissions
A resource assignment can be received. A first set of time-frequency resources in a subframe can be determined from the resource assignment. A second set of time-frequency resources in the subframe can be determined. The second set of time-frequency resources can be used for a second latency data transmission. The second set of time-frequency resources can overlap with at least a portion of the first set of time-frequency resources. A first latency data transmission in the subframe can be decoded based on the determined first and second set of time-frequency resources. The first latency transmission can have a longer latency than the second latency transmission.
