摘要： Embodiments include exemplary methods and/or procedures for receiving a physical uplink shared channel (PUSCH) in a cell of a time-division-duplexed (TDD) radio access network (RAN). Embodiments include determining whether remote base station interference is present in uplink transmissions in the cell and, based on the determining result, configuring activation or deactivation of code block group (CBG) based retransmissions in the cell, sending control messages to one or more UEs in the cell, for applying the configuration, and decoding subsequent PUSCH transmissions received from the one or more UEs based on the configuration. Embodiments also include network nodes configured to perform the exemplary methods and/or procedures.

摘要： The embodiments herein relate to timing advance offset for uplink/downlink switching in New Radio (NR). In one embodiment, there proposes a method in a wireless communication device, comprising: determining a timing advance (TA) offset for uplink/downlink switching, wherein the TA offset is at least based on the time offset requirement for uplink/downlink switching in different scenarios used in communication between the wireless communication device and a network node; applying the determined TA offset in the uplink communication from the wireless communication device to the network node. With embodiments herein, uplink/downlink switching time for NR is defined.

摘要： Systems and methods for flexible Cross-Link Interference (CLI) measurement reporting are provided. In some embodiments, a method performed by a wireless device for performing CLI measurements includes the wireless device receiving at least one CLI measurement configuration. The CLI measurement configuration includes a measurement resource and one or more resource Identities (IDs) of the measurement resource instead of the physical cell ID. The wireless device performs measurements on the measurement resource based on the CLI measurement configuration. Upon detecting that one of the measurements exceeds a threshold, the wireless device transmits a measurement report. The measurement report includes the measurement that exceeds the threshold and the one or more resource IDs of the respective measurement resource. This might allow for more flexible CLI reporting by enabling comparison of a range of different conditions so that the measurement reporting criteria may better detect scenarios where the CLI is an issue.

摘要： A method and device for two-step random accessing. The method includes transmitting a random access preamble and a data block on a time-frequency resource to a network device; and receiving a response message for the random accessing from the network device. The data block is encoded with an orthogonal cover code and/or a cyclic shift, and the data block comprises data information and a reference signal associated with the data information. Therefore, resource efficiency is improved significantly for an associated data message following a random access preamble with endurable minor performance degradation.

摘要： A method, network node and wireless device, WD, providing signaling mechanisms for enabling repetitions of messages related to random access, RA, are disclosed. According to one aspect, a network node transmits an indication of a number of zero or more repetitions of a message related to RA to be transmitted by the WD in response to a random access response, RAR, message transmitted to the WD. The network node further receives at least one message related to RA.

摘要： A method may be provided to operate a wireless terminal in communication with a network node. The method may include receiving a Physical Downlink Control Channel, PDCCH, order from the network node. The PDCCH order may include an identification for a Random Access CHannel RACH occasion to be used for a RACH message 1 preamble transmission. Moreover, the identification may include a first index that indicates a set of RACH occasions and a second index that indicates the RACH occasion associated with the set. The method may also include transmitting a Message 1 preamble to the network node using the RACH occasion responsive to the PDCCH order.
