Abstract: Methods, systems, and devices for wireless communications are described. A waveform for communications between a user equipment (UE) and a base station may be generated or decoded based on a resource allocation of a slot for the communications. In some cases, the UE may receive control information from the base station that indicates the resource allocation for the slot, where the slot contains a defined number of symbol periods (e.g., 14 symbol periods), or the defined number of symbol periods and at least one additional symbol period. The waveform may then be generated (e.g., transmitted) or decoded (e.g., received) based on the number of symbol periods in the slot. Additionally or alternatively, the UE and base station may identify an operating mode of the UE, identify allowed resource allocation sizes for generating or decoding the waveform, and generate or decode the waveform based on the allowed resource allocation sizes.

Abstract: Methods, systems, and devices for wireless communication are described. In some cases, due to blind decoding and channel estimation (CE) limits, one or more user equipment (UE) specific search sets may be pruned for blind decoding and/or CE purposes. For instance, after hashing a set of common decoding candidates to control channel elements (CCEs) within the control region, the UE specific search sets may be pruned so as to conform to the blind decode limitation, since a common search space has already occupied a portion of the total blind decode limit. Following pruning, the UE may hash the sets of UE-specific decoding candidates associated with the one or more UE specific search sets to CCEs within the control region. The UE may further prune UE specific search sets, based on CE limits, while reusing CE for overlapping hashed locations.

Abstract: Techniques are described for wireless communication. One method includes receiving, at a user equipment (UE), a transport block (TB) that includes a plurality of code block groups (CBGs); determining CBG failure information identifying a set of one or more CBGs in the TB that failed to decode at the UE; determining a compressed representation of the CBG failure information; and transmitting, in response to receiving the TB, hybrid automatic repeat request (HARQ) information including the compressed representation of the CBG failure information. The compressed representation of the CBG failure information includes fewer bits of information than the CBG failure information.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for sounding reference signal (SRS) coordination, power control, and synchronization for distributed coordinated multipoint (CoMP) using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications by a network entity includes determining a first amount of transmission (Tx) power for transmission of signals originating from a first cluster center that is connected to the network entity, determining a second amount of Tx power for transmission of signals originating from at least a second cluster center that is connected to the network entity, and transmitting signals for one or more user equipment (UEs) served by the first cluster center and one or more UEs served by the second cluster center based on the first amount of Tx power and the second amount of Tx power.

Abstract: Various aspects described herein relate to communicating uplink control information (UCI) in low-latency communications. A resource assignment is received from an access point to transmit over a first symbol and a second symbol that comprise a first TTI, wherein the resource assignment includes, at least for the first symbol, an indication of one or more consecutive frequency resources in a system bandwidth based on a decimation factor. A reference signal is transmitted in the first TTI over the first symbol and a data signal indicating UCI over the second symbol according to the resource assignment.

Abstract: Techniques for wireless communication are described. A method for wireless communication at a user equipment (UE) includes identifying a physical uplink shared channel (PUSCH) to transmit in an uplink pilot time slot (UpPTS) of a subframe, determining whether to transmit uplink control information (UCI) on the PUSCH in the UpPTS, and transmitting the PUSCH in the UpPTS based at least in part on the determining. A method for wireless communication at a network access device includes determining whether to schedule a transmission of UCI on a PUSCH in a UpPTS of a subframe, scheduling the PUSCH in the UpPTS based at least in part on the determining, and transmitting, to a UE, scheduling information for the PUSCH in the UpPTS.

Abstract: Certain aspects of the present disclosure relate to a method and apparatus for receiving a medium occupation and a resource block group (RBG) size from a gNB, wherein the radio block group size is based on a bandwidth part (BWP) configuration. In one example, UEs with smaller BWP have finer granularity in RBG size in terms of PRBs, while UEs with larger BWP may have a coarser granularity in RBG size in terms of PRBs. An additional guard band may be used if the gNB reserves some channels such that not all of the BW is occupied. For example, if the gNB reserves the 20 MHz channel, it may perform better by adding additional guard band on each side of the 20 MHz bandwidth to accommodate an adjacent channel leakage-power ratio (ACLR). Another aspect of the present disclosure relates to assigning a UE an interlace with equally spaced PRBs.

Abstract: Methods, systems, and devices for wireless communications are described. Examples may include receiving, at a user equipment (UE) a random access channel (RACH) configuration message from a base station, where the message indicates a channel metric (e.g., received signal strength indicator (RSSI), reference signal received power (RSRP), reference signal received quality (RSRQ), a signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR), or the like) and a threshold associated with the channel metric. The, UE may measure a reference signal (e.g., synchronization signal block (SSB), channel state information reference signal (CSI-RS), or the like) and select a RACH procedure based on comparing the measured channel metric to the threshold. For example, the UE may select a two-step RACH procedure if the measured channel metric satisfies the threshold specified in the configuration. In some cases, the UE may select a RACH procedure or a listen-before-talk (LBT) procedure based on a QoS parameter.

Abstract: Methods, systems, and devices for wireless communications are described that provide staggered synchronization signal blocks (SSBs) in frequency sub-bands for beamformed wireless communications. Transmissions of SSBs and control channel transmissions (e.g., remaining minimum system information (RMSI) physical downlink control channel (PDCCH) transmissions) may use multiple transmission beams in a beam sweeping procedure. The SSB transmissions may be transmitted using transmission beams that span one frequency sub-band of a number of available frequency sub-bands, and the control channel transmissions may use transmission beams that span two or more of the frequency sub-bands. The SSB beam sweeping procedure may be performed separately during staggered, non-overlapping time periods for each frequency sub-band of the number of frequency sub-bands. Each of the of SSBs may indicate a reference timing of the base station used to identify a set of resources (e.g., a control resource set (CORESET)) that carries control channel transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain a signal received over a wireless channel, the signal configuring one or more random access parameters for the wireless channel. The UE may obtain a downlink control signal over the wireless channel, wherein the downlink control signal comprises an indication of a trigger and a location of one or more random access occasions for the UE. The UE may output, based at least in part on the downlink control signal, a random access signal for transmission on the wireless channel during at least one of the one or more random access occasions and according to the one or more random access parameters and the location. The UE may establish a connection with a base station based at least in part on the random access signal.
