Abstract: Embodiments include systems and methods for UE signaling a network regarding customized ringing signal (CRS) capability and use of such information by the network. Various embodiments may receiving from the network an INVITE message notifying the UE of an incoming call, determining whether the INVITE message indicates that the network provides CRS service if the UE supports a CRS function, and including an indication in a response to the INVITE that the UE supports the CRS function in response to determining that the INVITE message includes an alert information header field indicating that the network provides CRS service. Various embodiments include a network computing device receiving such information and performing negotiations for CRS service with the UE only if the UE indicates CRS functional capability.

Abstract: In a communication between a user equipment (UE) and a network node, the UE may receive a grant of uplink (UL) shared channel (SCH) resources from the network node. Each of the UL SCH resources may be associated with one of a plurality of hybrid automatic repeat request (HARQ) processes. Each HARQ process may be at least one of a plurality of HARQ process types, and each HARQ process type may be based on HARQ feedback status and HARQ retransmission status. The UE may transmit a control message on one or more UL SCH resources in response to the one or more UL SCH resources being determined to be usable based on the HARQ process type of the HARQ processes associated with the one or more of the UL SCH resources.

Abstract: Various aspects described herein relate to communicating in a wireless network. A resource grant comprising an indicator of whether to transmit a demodulation reference signal (RS) for an uplink control channel or an uplink data channel can be received from a network entity. It can be determined whether to transmit the RS in at least one transmission time interval (TTI) based at least in part on the indicator.

Abstract: Disclosed are techniques for environment sensing. In an aspect, a transmitter base station determines a configuration for a radio frequency (RF) sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, and transmits the RF sensing signal to at least one receiver base station based on the configuration. In an aspect, a receiver base station receives a configuration for an RF sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, receives, from at least one transmitter base station, the RF sensing signal, and detects at least one target object based, at least in part, on reception of the RF sensing signal.

Abstract: Aspects relate to a base station configuring a user equipment (UE) with multiple (e.g., at least two) hybrid automatic repeat request (HARQ) feedback granularities. In some examples, a first HARQ feedback granularity may be for transmitting HARQ feedback in a first quantity of symbols and a second HARQ feedback granularity may be for transmitting HARQ feedback in a second quantity of symbols. The base station may send an indication to the UE that specifies which HARQ feedback granularity the UE is to use for sending HARQ feedback.

Abstract: Some techniques and apparatuses described herein provide generation of a set of orthogonal sequences for transmission of a signal including a payload using an orthogonal base sequence in a time domain. In one example, the orthogonal base sequence in the time domain may be a pi over 2 (pi/2) binary phase shift keying (BPSK) sequence in the time domain, such as prior to transform precoding for transmission. Some techniques and apparatuses described herein provide for the set of orthogonal sequences to be generated such that the set of orthogonal sequences are orthogonal within a symbol (e.g., an orthogonal frequency division multiplexing symbol) by applying an intra-symbol orthogonal cover code (OCC). Applying the intra-symbol OCC provides intra-symbol orthogonality. Thus, a peak to average power ratio of a user equipment is reduced for uplink transmissions and intra-symbol orthogonality is preserved

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, an indication of a time gap value associated with a random access channel (RACH) procedure, wherein the time gap value is based at least in part on a capability of the base station, determine whether a physical RACH (PRACH) occasion associated with the RACH procedure is valid based at least in part on receiving the indication of the time gap value associated with the RACH procedure, and selectively transmit, to the base station, a PRACH transmission in the PRACH occasion based at least in part on determining whether the PRACH occasion is valid. Numerous other aspects are provided.

Abstract: Some techniques and apparatuses described herein enable a base station to configure a CSI-RS resource set with one or more parameters that are linked to one or more parameters of least one of a message that triggers CSI-RS monitoring, a physical channel associated with the CSI-RS monitoring, or an uplink reference signal associated with the CSI-RS monitoring. This allows the one or more parameters of the CSI-RS resource set to be dynamically set and/or adjusted based at least in part on the one or more parameters to which the one or more parameters of the CSI-RS resource set are linked. As a result, scheduling flexibility for beam management, downlink communications, and/or uplink communications may be increased. This may reduce delays and increase network speed, reliability, and/or beam management efficiency. Numerous other aspects are provided.
