摘要： A scheduling algorithm is disclosed that allows mobile units (300), participating in an ongoing communications session, to temporary perform channel-demanding communications operations without ending the session and that is useful in the case of no free radio channels. The algorithm is based on selecting a radio channel (65) for transmitting a radio block (35) based on information of a previous radio channel (60), no which a previous radio block (35) has been transmitted. The radio block (35) and the previous radio block (30) are based on common information. A mobile unit (300) participating in the communications session selects whether to perform any channel-demanding communications operations on the selected radio channel (65). By limiting any such other channel-demanding operations to only the selected radio channel (65), the probability of loss of useful data for the mobile unit (300) during the communications session is minimized.

摘要： The invention relates to incremental redundancy schemes in wireless networks, where a number of sub-blocks, transmitted from the transmitting side, are received (S1) by the intended receiver on the receiving side. The idea according to the invention is to measure (S2), for at least one data block, the reception quality of received sub-blocks, and select (S3) which sub-block to set forth for transmission from the transmitting side based on the measured sub-block reception quality. For example, when all or several subblocks of a given data block have been received but the data block can still not be successfully decoded, it would normally be best to retransmit the sub-block that has the lowest quality. This generally increases the probability of successful decoding of the data block, thus increasing the throughput and reducing the delay.
摘要翻译：本发明涉及无线网络中的增量冗余方案，其中从发送侧发送的多个子块由接收侧的预期接收机接收（S1）。根据本发明的想法是对于至少一个数据块，对接收到的子块的接收质量进行测量（S2），并且基于（S2）从发送侧选择（S3）要发送的用于发送的子块测量子块接收质量。例如，当已经接收到给定数据块的全部或几个子块，但数据块仍然不能被成功解码时，通常情况下最好重发具有最低质量的子块。这通常增加了成功解码数据块的概率，从而增加了吞吐量并减少了延迟。

摘要： The invention involves selection of modulation scheme for a mobile unit (100) having access to a link quality enhancing algorithm (130) operable only on data modulated using a subset of the available modulation schemes. The mobile unit (100) performs signal quality measurements on a communications link (410), over which data modulated with a first modulation scheme is communicated. A link quality measure is then determined for this first modulation. A quality enhancement due to operation of the algorithm (130) is also determined. This quality measure and the quality enhancement are used for generating decision information, which is reported to the network (200). There the information is used for estimating link quality measure(s) of currently non-employed modulation(s) for the mobile unit (100). The selection of a modulation scheme for the communications link is then performed based on the decision information and the estimated quality measure(s).

摘要： A method for accessing a cellular communications network in unlicensed spectrum is provided. More specifically, the method is related to performing a Listen-Before-Talk (LBT) procedure prior to transmitting a Physical Random Access Channel (PRACH) preamble for accessing a New Radio- Unlicensed (NR-U) network. A User Equipment (UE) first performs the LBT procedure. If the LBT procedure is successful, the UE then generates a punctured PRACH preamble and transmits the punctured PRACH preamble. By puncturing the PRACH preamble, it is possible to create a gap(s) for performing the LBT procedure in a way that is backward compatible with existing NR-U specification and does not reduce a number of random access occasions in a slot or a mini-slot. As a result, it is possible to transmit PRACH preambles in consecutive random access occasions, thus helping to increase spectrum utilization and reduce latency in the cellular communications network.

摘要： According to certain embodiments, a method performed by a wireless device comprises initiating a random access procedure in which the wireless device sends a Physical Random Access Channel, PRACH, preamble to a network node and applying a receiver configuration for receiving an access response. The receiver configuration is determined based at least in part on whether a many-to-one association exists between (a) a downlink signal that can be used for beam selection prior to initiating the random access procedure, and (b) PRACH preamble indices.
