Abstract: Apparatus, methods, and computer program products for serving cell measurement based on CSI-RS RRM are provided. An example apparatus may transmit, to a base station, an indication indicating support for reporting one or more serving cell channel state information reference signal (CSI-RS) radio resource management (RRM) measurements independent of non-serving cell CSI-RS RRM measurements. The example apparatus may receive, from the base station, a configuration of layer 3 measurement resources. The example apparatus may perform, based on the configuration of the layer 3 measurement resources, the one or more serving cell CSI-RS RRM measurements. The example apparatus may transmit, to the base station, the one or more serving cell CSI-RS RRM measurements for a serving cell.

Abstract: A user equipment (UE) may make a joint decision of adaptive receive diversity (ARD) and adaptive transmit diversity (ATD) configurations, including transmit (Tx) and receive (Rx) antennas selection and/or blanking based on downlink (DL) and uplink (UL) traffic conditions. The UE may disable at least one Tx chain for a transmission of a codebook-based sounding reference signal (SRS) (SRS-CB) based on one or more of at least one DL traffic condition or at least one UL traffic condition, and transmit, to a base station, upon disabling the at least one Tx chain, the SRS-CB via an antenna associated with at least one active Tx chain.

Abstract: Methods, systems, and devices for interleaved mapping are described. In some implementations, a transmitting device identifies a set of virtual resource blocks (VRBs) corresponding to at least one code block to be transmitted to a receiving device. The transmitting device may determine that a quantity of VRBs to be transmitted to the receiving device is different than a quantity of entries within a regular interleaving matrix. Thus, the transmitting device may map each of the VRBs to a physical resource block (PRB) according to an irregular interleaving matrix to generate at least one interleaved code block. The transmitting device may transmit the interleaved code block to the receiving device. The receiving device may receive the interleaved code block and identify the PRBs associated with the interleaved code block. The receiving device may map each PRB within the interleaved code block to a VRB according to an irregular deinterleaving matrix.

Abstract: Methods, systems, and devices for wireless communications are described that provide for antenna selection at a user equipment (UE). The UE may have a set of available antennas for uplink and downlink communications, and may select a first subset of antennas for uplink communications and a second subset of antennas for downlink communications. The first subset of antennas may be based on one or more uplink metrics, and the second subset of antennas may be based on the first subset of antennas and one or more downlink channel metrics, traffic amounts, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may identify a capability for downlink control channel monitoring and uplink cancellation indication monitoring. The UE may transmit, to a base station, an indication of the identified uplink cancellation indication monitoring capability. The base station may receive the indication from the UE, and may configure monitoring occasions in a slot based on the received uplink cancellation indication monitoring capability. The base station may transmit via radio resource control signaling, and the UE may receive, a configuration which configures a number of monitoring occasions based on the uplink cancellation indication monitoring capability. The UE may then monitor the configured monitoring occasions according to the identified capability.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently limiting a number of blind decoding attempts or control channel elements (CCEs) that a user equipment (UE) is configured to monitor to limit complexity at the UE. When a UE is configured to use blind decoding for monitoring CCEs in multiple spans in a slot for control information from a base station, the UE may be configured to perform dropping of blind decoding candidates or CCEs in a first temporal span in the slot. In other words, the UE may identify a dropping rule to drop CCE monitoring occasions or blind decoding attempts in excess of a maximum number of non-overlapping CCEs per span or a maximum number of blind decoding attempts per span, respectively, and the UE may apply the dropping rule to the first temporal span within the slot.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method for wireless communications at a user equipment (UE) includes determining one or more performance metrics related to communications over a wireless channel and comparing the one or more performance metrics with a performance level for the communications over the wireless channel. The method may include selecting a power mode for the UE based at least in part on the comparing and determining an operating state of a subset of a plurality of radio frequency front end elements of at least one active radio frequency chain of the UE based at least in part on the power mode and a priority of the one or more performance metrics. The method may also include adjusting the subset of the plurality of radio frequency front end elements based at least in part on the operating state.

Abstract: This disclosure provides systems, methods and apparatus where a user equipment (UE) may indicate different physical downlink control channel (PDCCH) monitoring capabilities (such as UE capabilities in terms of the number of control channel elements (CCEs), blind decodes (BDs), number of downlink control information (DCI) formats, etc.) per monitoring span or slot. For example, a UE may support a different number of CCEs per slot or a different number of DCIs per monitoring span for different service types (such as a different number of CCEs for enhanced mobile broadband (eMBB) and for ultra-reliable low latency communications (URLLC)). A UE may indicate different sets of PDCCH monitoring capabilities (such as sets of PDCCH monitoring capabilities for different service types, monitoring spans, slots, etc.). A base station may receive the indication of UE PDCCH monitoring capability information, and may configure the UE with one or more monitoring occasions accordingly.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Techniques are described herein for performing out-of-order processing. The UE may receive a first downlink channel at a first time and a second downlink channel at a second time. The UE may determine that a priority of the second downlink channel is different (e.g., higher) than a priority of the first downlink channel. The UE may determine that a first uplink transmission associated with the first downlink channel is to be transmitted after a second uplink transmission associated with the second channel based on the different priorities. The UE may set one or more operations based on these determinations. In some cases, the UE may suspend processing the of the first downlink channel to process the second downlink channel.

Abstract: Systems and methodologies are described that facilitate transmitting access point types and/or restricted association parameters using broadcast signals, such as beacons, pilot signals, etc. The type or restricted association information can be indicated by one or more intrinsic aspects of the signal, such as specified parameters. In addition, the type or information can be indicated by one or more extrinsic signal aspects, such as frequency, interval, periodicity, etc. Using this information, a mobile device can determine whether an access point implements restricted association. If so, the mobile device can request an access point or related group identifier before determining whether to establish connection therewith. The identifier can be verified against a list of accessible access points and/or groups to make the determination.
