Abstract: Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.

Abstract: Aspects herein relate to inter-cell interference randomization between two or more cells. For example, a network entity may determine a cell identifier associated with the network entity and perform at least one of an interleaving, rate-matching, or resource element mapping on at least one codeword based on the cell identifier. The network entity may further communicate with a user equipment (UE) in accordance with performing at least one of the interleaving, rate-matching, or resource element mapping on the at least one codeword. In another example, a UE may receive a message from a network entity on a communication channel and identify a cell identifier associated with the network entity. The UE may further perform at least one of a de-interleaving, de-rate-matching, or resource element de-mapping on the message based on the cell identifier.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may identify a first channel group comprising a first radio bearer and a second channel group comprising a set of second radio bearers. In some examples, the first channel group further comprising a one-to-one mapping between the first radio bearer and a first channel of a backhaul network and the second channel group comprising a many-to-one mapping between the set of second radio bearers and a second channel of the backhaul network. The transmitting device may transmit a first packet on the first channel of the first channel group of the backhaul network, the first packet comprising a mapping indicator set to a first value and a first identifier associated with the first channel of the first channel group.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a downlink (DL) signal from a base station on DL beam(s). The UE may identify a selected DL beam of the DL beam(s) for communications from the base station to the UE. The UE may transmit a random access channel (RACH) message to the base station using at least one of a resource or a RACH waveform selected based at least in part on the selected DL beam.

Abstract: Methods, systems, and devices for wireless communication are described. A first wireless node may establish a wireless connection between the first wireless node and a second wireless node in a wireless backhaul communications network. The first wireless node may identify, at the first wireless node, a need for additional resources for wireless communications with a third wireless node. The first wireless node may transmit a request message to the second wireless node indicating that resources are requested at the first wireless node. The first wireless node may receive an indication of one or more available resources from the second wireless node. The first wireless node may select one or more of the available resources for wireless communications with the third wireless node.

Abstract: Techniques are described herein for periodically transmitting a first set of signals (e.g., reference signals) during an on-period of a discontinuous reception (DRX) cycle rather than during an off-period of the DRX cycle. Such techniques may enable a user equipment (UE) operating in a DRX mode to conserve additional power during the DRX cycle. A periodicity for transmitting the first set of signals during the on-period may be determined. The periodicity may indicate that every one-in-N DRX cycles, the first set of signals are to be transmitted during the on-period. During other DRX cycles, the first set of signals may be transmitted during the off-period. When the first set of signals are transmitted during the on-period, the UE may refrain from activating certain components during the off-period, thereby conserving power.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a paging indicator message to one or more user equipment (UEs) in a group of UEs. The base station may receive, based at least in part on the paging indicator message, a first response message from the one or more UEs. The first response message may be received using a resource that is shared with a random access channel message for the group of UEs. The base station may transmit, based at least in part on the first response message, a second response message to the one or more UEs.

Abstract: Methods, systems, and devices for wireless communication are described. A network device, such as a base station, may transmit a request message to a user equipment (UE). The request message may include a request for the UE to transmit a set of sounding reference signals (SRSs). The set of SRSs may include two (or more) beamformed signals. The network device may receive the set of SRSs according to the request message. The network device may identify, based on a co-phasing parameter associated with the two (or more) beamformed signals, an antenna port precoder configuration to use for communicating with the UE.

Abstract: A base station may transmit scheduling information comprising one or more first downlink messages to a first user equipment (UE) in a first beam. The base station may transmit one or more second downlink messages to a second UE in a second beam. In response to the transmission of the one or more first downlink messages, the base station may receive one or more first uplink control messages from the first UE in a time slot. In response to the transmission of the one or more second downlink messages, the base station may receive one or more second uplink control messages from the second UE in the same time slot. The one or more second uplink control messages may be frequency-orthogonal or spreading code-orthogonal to the one or more first uplink control messages.
