摘要: Certain aspects of the present disclosure provide techniques for enhancing sidelink resource utilization for a user equipment (UE) that supports full duplex (FD) communications. For example, an FD UE may receive incoming sidelink communication over a first set of resources and, in FD mode, simultaneously transmit another sidelink communication over the same first set of resources. According to aspects of the present disclosure, the potential interference between the two sidelink communications will be mitigated or reduced, such as by having the FD UE negotiate with other sidelink UEs over transmission power levels and related aspects, such as beam coordination and/or resource subset designation, or the like.

摘要: Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, DCI associated with SPS. The apparatus may also identify whether the DCI is EH SPS activation DCI, EH SPS reactivation DCI, data SPS activation DCI, data SPS reactivation DCI, or SPS release DCI, the EH SPS activation DCI and the EH SPS reactivation DCI corresponding to an EH configuration, the data SPS activation DCI and the data SPS reactivation DCI corresponding to a data processing configuration. Additionally, the apparatus may configure an EH component associated with the EH configuration if the DCI is the EH SPS activation DCI or the EH SPS reactivation DCI, or performing data processing associated with the data processing configuration if the DCI is the data SPS activation DCI or the data SPS reactivation DCI.

摘要: Methods, systems, and devices for wireless communications are described. The described techniques provide for a victim network entity to share a downlink preemption pattern with user equipments (UEs) and neighboring network entities. For example, the victim network entity may transmit, to a UE and/or a neighbor network entity, control signaling indicating a recurring downlink preemption pattern defining one or more resources during which the UE may preempt reception of downlink signaling and the victim and neighbor network entities may preempt transmission of downlink signaling. The UE and the network entities may refrain from monitoring for downlink transmissions and transmitting downlink transmissions, respectively, in accordance with the indicated downlink preemption pattern. In some examples, the UE and the network entities may be configured with one or more conditions for discarding the indicated downlink preemption pattern and monitoring the one or more resources for or transmitting downlink transmissions.

摘要: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to transmit one or more reference signals to a second wireless device using a first antenna array at the first wireless device and in accordance with a first precoder matrix. The first wireless device may receive, from the second wireless device based on the one or more reference signals, a feedback message indicating an estimated rotational misalignment, an estimated spatial misalignment, or both, between the first antenna array at the first wireless device and a second antenna array at the second wireless device. The first wireless device may then transmit a message to the second wireless device in accordance with a second precoder matrix that is modified relative to the first precoder matrix based at least in part on the estimated rotational misalignment, the estimated spatial misalignment, or both.

摘要: Methods, systems, and devices for wireless communication are described to estimate interference for concurrent uplink and downlink communications based on an indication of one or more one or more characteristics of an interfering uplink signal communicated between a base station and a second user equipment (UE). The base station or the second UE may transmit, to a first UE, an indication of one or more characteristics of an uplink signal, such as a baseband of the uplink signal or one or more parameters of the uplink signal. The first UE may use the characteristic(s) of the uplink signal to estimate the baseband of the uplink signal and cancel interference associated with the uplink signal. For example, the first UE may use the baseband signal to estimate the interference and may subtract the estimated interference from a downlink signal received at the first UE.

摘要: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may receive control signaling indicating a set of configurations including a set of random access channel (RACH) configurations or a set of scheduling request (SR) configurations. At least one RACH configuration of the set of RACH configurations includes a UE-group common RACH configuration or at least one SR configuration of the set of SR configurations includes a UE-group common SR configuration. The UE may select one or more configurations of the set of RACH configurations or the set of SR configurations based on receiving the control signaling and may perform the wireless communications.

摘要: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that indicates a configuration for subband full duplex (SBFD) slots and a random access channel (RACH) configuration for SBFD slots. The UE may transmit at least one instance of a RACH message in an uplink subband of an SBFD slot in accordance with the RACH configuration. The RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across an SBFD slot and an uplink slot. The RACH configuration may map synchronization signal blocks (SSB)s to RACH occasions in the uplink subband of the SBFD slot. In some examples, the SSBs may be mapped across multiple (e.g., consecutive) SBFD slots. In some cases, the RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across multiple SBFD slots.

摘要: Methods, systems, and devices for wireless communications are described. A frequency band configuration for a full-duplex slot may be indicated, where a frequency band configuration may include one or more downlink frequency bands and one or more uplink frequency bands. In some cases, a frequency band configuration may also include one or more guard bands. A user equipment (UE) may determine the frequency band configuration for a full-duplex slot based on a frequency configuration indication, which may include an index for a table of frequency band configurations, one or more bitmaps, or respective start and length indications for each frequency band. A frequency band configuration may apply to one slot or to multiple slots.

摘要: Systems and methods in which one or more wireless communication stations implement duplex-mode remediation to facilitate the signal communication when an issue with respect to self-interference is identified are described. Duplex-mode remediation may be implemented for various communication scenarios, such as for random access phase communications, for communications having different priorities, etc. A wireless communication station may implement one or more changes with respect to the full duplex operation of the wireless communication station based upon determining that an issue with respect to self-interference may be, or is being, experienced, such as to provide for a wireless communication station operating in an in-band full duplex mode to increase interference cancellation and/or to fall back to a sub-band full duplex mode or a half duplex mode, to provide for a wireless communication station operating in a sub-band full duplex mode to increase interference cancellation and/or to fall back to a half duplex mode.

摘要: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for collision handling. A first network node receives a first allocation of first resources at a first time and receives a second allocation of second resources at a second time, wherein the first time is before the second time, wherein one or more of the first resources overlap in a time domain and a frequency domain with one or more of the second resources, and wherein the first resources are uplink resources and the second resources are downlink resources or the first resources are downlink resources and the second resources are uplink resources. The first network node adjusts for the overlap in the time domain and the frequency domain between the first allocation of first resources and the second allocation of second resources.
