摘要： Disclosed is a method for accelerating bit error correction in a receiver in a radio communication network such as (5)G NR, wherein the receiver is configured to update soft bit values associated with each code bit of a block code based on parallel parity checks. The method comprises receiving (101) a block code encoded message, and for any group of two or more rows of a parity-check matrix of the block code: when the two or more rows are nonoverlapping (102): combining (103) the two or more rows in a row group for parallel updating, updating (104), in parallel, the parity checks of the row group for the received message, and forming (107) a message estimate based on the updated parity checks. Corresponding computer program product, apparatus, and receiver are also disclosed. Some embodiments further comprise, when the two or more rows are overlapping in one shared bit: combining (105) the two or more rows in a row group for parallel updating, updating (106) the parity checks of the row group for the received message by: collecting (106a) available bit-to-check values except from the shared bit, computing (106b) shared check-to-bit values towards the shared bit based on the collected bit-to-check values, computing (106c) shared bit-to-check values for the shared bit based on the computed shared check-to-bit values, computing (106d) new check-to-bit values for all remaining bits, and parallel updating (106e) of the parity checks of the row group for the received message based on the computed check-to-bit values.

摘要： A radio device (100) sends a radio transmission (503, 507) to a further radio device (150). Further, the radio device (100) receives a further radio transmission (505, 509) from the further radio device (150). The further radio transmission (505, 509) comprises an indicator of reception success. In response to the indicator being toggled with respect to a previous state of the indicator, the radio device (100) determines that the radio transmission (509) was successfully received by the further radio device (150). In response to the indicator not being toggled with respect to the previous state of the indicator, the radio device (100) determines that the radio transmission (503) failed.

摘要： To increase throughput efficiency and attain a higher achieved bit rate for data transmissions over a high speed shared channel, a variable transmit power increase factor is used to control the maximum rate at which the power at which data is transmitted over the high speed shared channel can increase. In one non-limiting implementation, the power increase factor F is varied with the current total downlink transmitted power available for high speed downlink transmission. For example, when the available high speed shared channel power is large, the variable transmit power increase factor assumes a more conservative value, e.g., a smaller F value, at the beginning of the high speed downlink transmission, and then a more liberal value, e.g., a larger F value, later during the high speed downlink transmission.

摘要： A technique is provided for processing data in a packet-based communications environment. A single data packet is encapsulated into a single link layer packet data unit. The link layer unit is encoded to form at least one code block. After the currently available radio resource capacity during a fixed duration transmission interval has been determined, bits within the code block are selected to fit into or otherwise match the radio resource capacity. Thereafter, the selected bits are transmitted via a physical layer. In some variations, unsolicited redundant sets of bits are transmitted thereafter to facilitate successful receipt.

摘要： A serving RNC signals the load contribution of all mobiles for which it is the serving RNC to all cells controlled by another RNC that are affected by the uplink transmissions of those mobiles. This allows the other RNC to determine the contribution of those mobiles to the total uplink interference in its cells. In one example, the uplink load may be estimated using mobile-based path gain measurements.

摘要： Methods are disclosed for generation of a resulting bit sequence for use in communication involving a user equipment served by a cell of a communication network. The resulting bit sequence is based on a first constituent sequence, the first constituent sequence being defined by recursion based on seed with dynamic value. One example method comprises (for a relevant seed value comprising first and second constituent seed values, and for each desired bit position of the resulting bit sequence) acquiring a first bit value for a corresponding bit position of a pre-stored intermediate sequence, acquiring a second bit value for each of one or more shifted positions of a pre-stored version of the first constituent sequence for a single-bit seed value, and determining a bit value of the desired bit position of the resulting bit sequence as a sum of the first bit value and the one or more second bit values. The pre-stored intermediate sequence is based on the first constituent sequence for the first constituent seed value. The single-bit seed value has a single non-zero bit. Each of the one or more shifted positions is determined by the desired bit position, the position of the non-zero bit of the single-bit seed value, and the position of a non-zero bit of the second constituent seed value. Other example methods, as well as corresponding apparatuses, storage unit, transmitter, receiver, communication device and computer program product are also disclosed.
