摘要: Various aspects of the present disclosure generally relate to wireless communication. Some aspects generally relate to reducing interference in a user equipment (UE) with respect to non-cell defining synchronization signal and physical broadcast channel block (NCD-SSB) communications. Some aspects more specifically relate to configuring the UE to mitigate interference caused by collisions between the NCD-SSB and a cell-defining SSB (CD-SSB). Some aspects more specifically relate to configuring the UE to mitigate interference and/or other issues that might occur when at least a portion of the NCD-SSB is received during one or more downlink slots or symbols and one or more uplink slots or symbols.

摘要: A second user equipment can be configured to communicate with a first user equipment via sidelink. The second user equipment can receive, from the first user equipment, a first set of preferred radio resources. The second user equipment can determine a second set of radio resources based on radio signals received at the second user equipment. The second user equipment can select at least one radio resource for transmitting data to the first user equipment from within an intersection of the first set of preferred radio resources and the second set of radio resources.

摘要: A method, apparatus and system for medium access control is provided. Time slots configured to include mini slots at the beginnings thereof. Devices are assigned time slot, mini slot combinations as transmission opportunities. A device can attempt to use a transmission opportunity when it has a packet to send, by beginning data transmission in its assigned slot and mini slot and potentially continuing the transmission up until the end of the assigned slot. If another device is already transmitting in the assigned slot, the device refrains from using its transmission opportunity. Higher priority devices can be assigned transmission opportunities corresponding to earlier mini slots within a slot. In some embodiments, multiple devices can be assigned the same transmission opportunity and a collision detection mechanism can be employed. In some embodiments, all devices detect if a slot is idle and advance the beginning of the next slot upon such detection.

摘要: Methods, systems, and devices for wireless communications are described. A wireless device may receive a configuration for a first random access message of a two-step random access channel procedure. The wireless device may select a subcarrier spacing and a number of demodulation reference signal occurrences for transmitting the first random access message based at least in part on the configuration and a speed of the wireless device. The wireless device may transmit the first random access message of the two-step random access channel procedure using the subcarrier spacing and the number of demodulation reference signal occurrences.

摘要: A user equipment (UE), or other network component can operate to configure channel occupancy time (COT) sharing in random access procedures involving the unlicensed spectrum. At least some of the messages for the procedures can share a COT by configuring one or more gaps or listen-before-talk (LBT) procedures based on the gap or whether the COT sharing is UE or gNB initiated. Some configurations can depend on a location in the random access procedure that COT sharing is acquired.

摘要: Disclosed are a method and device for random access in a wireless communication system. A method by which a terminal performs random access in a wireless communication system according to one embodiment disclosed herein comprises the steps of: receiving, from a network, configuration information related to a first preamble group for a first-type feature; transmitting a first message to the network on the basis of a preamble selected from the first preamble group; and transmitting, to the network, a second message including a logical channel identifier (LCID) associated with a second-type feature, wherein the terminal may support both the first-type feature and the second-type feature.

摘要: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel access for wireless communications. One aspect provides a method for wireless communications at a user equipment (UE). The method generally includes obtaining a channel occupancy time (COT) structure information (COT-SI) message and obtaining at least one downlink control information (DCI) indicating multiple beams and listen before talk (LBT) scheme indications associated with the multiple beams. The method generally includes determining an LBT scheme to be used for transmission via each of the multiple beams based on the LBT scheme indications and the COT-SI message, and outputting signaling for transmission on each of the multiple beams based on the LBT scheme.

摘要: A user equipment apparatus (UE) includes processor(s) and memory storing instructions. The instructions, when executed by the processor(s), cause the UE at least to, establish a connection with a control network node via a serving cell, where the serving cell is supported by a source network node; receive, from the control network node and/or the source network node, timing advance (TA) cell configurations for a set of timing advance (TA) cells, where the TA cell configurations include a TA-associated random access (RA) configuration, where the set of TA cells includes first TA cells that include candidate target cells with which the UE may connect and/or other TA cells which are requested by at candidate target cells and which the UE may connect with in case the UE connects with the one of the candidate target cells; and acquire TA for the TA cell based on the TA-associated RA configuration.
