The foregoing has outlined rather broadly the features and technical advantages of examples according to the disclosure in order that the detailed description that follows may be better understood Additional features and advantages will be described hereinafter.

The embodiments of <FIG> and their associated text are part of the invention and covered by the claims. All other exemplary embodiments disclosed below are merely explanatory, and are not part of the invention.

In some aspects, the wireless network <NUM> may include one or more non-terrestrial network (NTN) deployments in which a non-terrestrial wireless communication device may include a UE (referred to herein, interchangeably, as a "non-terrestrial UE"), a BS (referred to herein, interchangeably, as a "non-terrestrial BS" and "non-terrestrial base station"), a relay station (referred to herein, interchangeably, as a "non-terrestrial relay station"), and/or the like. As used herein, an NTN may refer to a network for which access is facilitated by a non-terrestrial UE, non-terrestrial BS, a non-terrestrial relay station, and/or the like.

The wireless network <NUM> may include any number of non-terrestrial wireless communication devices. A non-terrestrial wireless communication device may include a satellite, a manned aircraft system, an unmanned aircraft system (UAS) platform, and/or the like. A satellite may include a low-earth orbit (LEO) satellite, a medium-earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, and/or the like. A manned aircraft system may include an airplane, helicopter, a dirigible, and/or the like. A UAS platform may include a high-altitude platform station (HAPS), and may include a balloon, a dirigible, an airplane, and/or the like. A non-terrestrial wireless communication device may be part of an NTN that is separate from the wireless network <NUM>. Alternatively, an NTN may be part of the wireless network <NUM>. Satellites may communicate directly and/or indirectly with other entities in wireless network <NUM> using satellite communication. The other entities may include UEs (e.g., terrestrial UEs and/or non-terrestrial UEs), other satellites in the one or more NTN deployments, other types of BSs (e.g., stationary and/or ground-based BSs), relay stations, one or more components and/or devices included in a core network of wireless network <NUM>, and/or the like.

For example, in some aspects, the wireless network <NUM> may be, include, or be included in a wireless backhaul network, sometimes referred to as an integrated access and backhaul (IAB) network. In an IAB network, at least one base station (e.g., base station <NUM>) may be an anchor base station that communicates with a core network via a wired backhaul link, such as a fiber connection. An anchor base station may also be referred to as an IAB donor (or IAB-donor), a central entity, a central unit, and/or the like. An IAB network may include one or more non-anchor base stations, sometimes referred to as relay base stations or IAB nodes (or IAB-nodes). The non-anchor base station may communicate directly with or indirectly with (e.g., via one or more non-anchor base stations) the anchor base station via one or more backhaul links to form a backhaul path to the core network for carrying backhaul traffic. Backhaul links may be wireless links. Anchor base station(s) and/or non-anchor base station(s) may communicate with one or more UEs (e.g., UE <NUM>) via access links, which may be wireless links for carrying access traffic.

In some aspects, a radio access network that includes an IAB network may utilize millimeter wave technology and/or directional communications (e.g., beamforming, precoding and/or the like) for communications between base stations and/or UEs (e.g., between two base stations, between two UEs, and/or between a base station and a UE). For example, wireless backhaul links between base stations may use millimeter waves to carry information and/or may be directed toward a target base station using beamforming, precoding, and/or the like. Similarly, wireless access links between a UE and a base station may use millimeter waves and/or may be directed toward a target wireless node (e.g., a UE and/or a base station). In this way, inter-link interference may be reduced.

Some UEs may be considered a customer premises equipment (CPE).

The symbols from transmit processor <NUM> may be precoded by a TX MIMO processor <NUM> if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM) and transmitted to base station <NUM>.

In some aspects, memory <NUM> and/or memory <NUM> may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station <NUM> and/or the UE <NUM>, may cause the one or more processors, the UE <NUM>, and/or the base station <NUM> to perform or direct operations of, for example, process <NUM> of <FIG>, process <NUM> of <FIG>, process <NUM> of <FIG>, process <NUM> of <FIG>, and/or other processes as described herein.

<FIG> is a diagram illustrating an example <NUM> of sidelink communications, in accordance with various aspects of the present disclosure.

As shown in <FIG>, a first UE <NUM>-<NUM> may communicate with a second UE <NUM>-<NUM> (and one or more other UEs <NUM>) via one or more sidelink channels <NUM>. The UEs <NUM>-<NUM> and <NUM>-<NUM> may communicate using the one or more sidelink channels <NUM> for P2P communications, D2D communications, V2X communications (e.g., which may include V2V communications, V2I communications, and/or the like), mesh networking, and/or the like. In some aspects, the UEs <NUM> (e.g., UE <NUM>-<NUM> and/or UE <NUM>-<NUM>) may correspond to one or more other UEs described elsewhere herein, such as UE <NUM>. In some aspects, the one or more sidelink channels <NUM> may use a PC5 interface and/or may operate in a high frequency band (e.g., the <NUM> band). Additionally, or alternatively, the UEs <NUM> may synchronize timing of transmission time intervals (TTIs) (e.g., frames, subframes, slots, symbols, and/or the like) using global navigation satellite system (GNSS) timing.

As further shown in <FIG>, the one or more sidelink channels <NUM> may include a physical sidelink control channel (PSCCH) <NUM>, a physical sidelink shared channel (PSSCH) <NUM>, and/or a physical sidelink feedback channel (PSFCH) <NUM>. The PSCCH <NUM> may be used to communicate control information, similar to a physical downlink control channel (PDCCH) and/or a physical uplink control channel (PUCCH) used for cellular communications with a base station <NUM> via an access link or an access channel. The PSSCH <NUM> may be used to communicate data, similar to a physical downlink shared channel (PDSCH) and/or a physical uplink shared channel (PUSCH) used for cellular communications with a base station <NUM> via an access link or an access channel. For example, the PSCCH <NUM> may carry sidelink control information (SCI) <NUM>, which may indicate various control information used for sidelink communications, such as one or more resources (e.g., time resources, frequency resources, spatial resources, and/or the like) where a transport block (TB) <NUM> may be carried on the PSSCH <NUM>. The TB <NUM> may include data. The PSFCH <NUM> may be used to communicate sidelink feedback <NUM>, such as hybrid automatic repeat request (HARQ) feedback (e.g., acknowledgement or negative acknowledgement (ACK/NACK) information), transmit power control (TPC), a scheduling request (SR), and/or the like.

In some aspects, the one or more sidelink channels <NUM> may use resource pools. For example, a scheduling assignment (e.g., included in SCI <NUM>) may be transmitted in subchannels using specific resource blocks (RBs) across time. In some aspects, data transmissions (e.g., on the PSSCH <NUM>) associated with a scheduling assignment may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, a scheduling assignment and associated data transmissions are not transmitted on adjacent RBs.

In some aspects, a UE <NUM> may operate using a transmission mode where resource selection and/or scheduling is performed by the UE <NUM> (e.g., rather than a base station <NUM>). In some aspects, the UE <NUM> may perform resource selection and/or scheduling by sensing channel availability for transmissions. For example, the UE <NUM> may measure a received signal strength indicator (RSSI) parameter (e.g., a sidelink-RSSI (S-RSSI) parameter) associated with various sidelink channels, may measure a reference signal received power (RSRP) parameter (e.g., a PSSCH-RSRP parameter) associated with various sidelink channels, may measure a reference signal received quality (RSRQ) parameter (e.g., a PSSCH-RSRQ parameter) associated with various sidelink channels, and/or the like, and may select a channel for transmission of a sidelink communication based at least in part on the measurement(s).

Additionally, or alternatively, the UE <NUM> may perform resource selection and/or scheduling using SCI <NUM> received in the PSCCH <NUM>, which may indicate occupied resources, channel parameters, and/or the like. Additionally, or alternatively, the UE <NUM> may perform resource selection and/or scheduling by determining a channel busy rate (CBR) associated with various sidelink channels, which may be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE <NUM> can use for a particular set of subframes).

In the transmission mode where resource selection and/or scheduling is performed by a UE <NUM>, the UE <NUM> may generate sidelink grants, and may transmit the grants in SCI <NUM>. A sidelink grant may indicate, for example, one or more parameters (e.g., transmission parameters) to be used for an upcoming sidelink transmission, such as one or more resource blocks to be used for the upcoming sidelink transmission on the PSSCH <NUM> (e.g., for TBs <NUM>), one or more subframes to be used for the upcoming sidelink transmission, a modulation and coding scheme (MCS) to be used for the upcoming sidelink transmission, and/or the like. In some aspects, a UE <NUM> may generate a sidelink grant that indicates one or more parameters for semi-persistent scheduling (SPS), such as a periodicity of a sidelink transmission. Additionally, or alternatively, the UE <NUM> may generate a sidelink grant for event-driven scheduling, such as for an on-demand sidelink message.

<FIG> is a diagram illustrating an example <NUM> of sidelink communications and access link communications, in accordance with various aspects of the present disclosure.

As shown in <FIG>, a transmitter (Tx)/receiver (Rx) UE <NUM> and an Rx/Tx UE <NUM> may communicate with one another via a sidelink, as described above in connection with <FIG>. As further shown, in some sidelink modes, a base station <NUM> may communicate with the Tx/Rx UE <NUM> via a first access link. Additionally, or alternatively, in some sidelink modes, the base station <NUM> may communicate with the Rx/Tx UE <NUM> via a second access link. The Tx/Rx UE <NUM> and/or the Rx/Tx UE <NUM> may correspond to one or more UEs described elsewhere herein, such as the UE <NUM> of <FIG>. Thus, a direct link between UEs <NUM> (e.g., via a PC5 interface) may be referred to as a sidelink, and a direct link between a base station <NUM> and a UE <NUM> (e.g., via a Uu interface) may be referred to as an access link. Sidelink communications may be transmitted via the sidelink, and access link communications may be transmitted via the access link. An access link communication may be either a downlink communication (from a base station <NUM> to a UE <NUM>) or an uplink communication (from a UE <NUM> to a base station <NUM>).

<FIG> is a diagram illustrating an example <NUM> of communications in a network, in accordance with various aspects of the present disclosure. As shown, a first wireless communication device (WCD <NUM>), a second wireless communication device (WCD <NUM>), a third wireless communication device (WCD <NUM>), and a fourth wireless communication device (WCD <NUM>) may communicate in a network. The network may be any type of network in which devices may communicate with other devices using beamforming techniques. For example, the network may be a millimeter wave network. In some cases, the network may be a sidelink network and/or an IAB network, among other examples. In some aspects, one or more of the WCDs may be, include, or be included in a UE, a base station, and/or an IAB node.

The WCD <NUM> may be scheduled to transmit a first future communication to WCD <NUM> using a beam <NUM>. The beam <NUM> may include an expanding coverage area (e.g., beam width) indicated by the area inside the two dashed arrows in <FIG>. A future communication is a communication that is to occur at some time in the future. Other WCDs may be scheduled to transmit and/or receive future communications using beams within the coverage area of the beam <NUM>.

For example, as indicated in <FIG>, the WCD <NUM> may intend to receive a second future communication. The WCD <NUM> and/or the device that is transmitting that second future communication to the WCD <NUM> may be configured to select resources to mitigate and/or minimize interference between the first and second future communications. To facilitate avoidance of interference, WCDs may transmit announcements that indicate future communications. In some aspects, announcements may include transmission (Tx) announcements (shown in <FIG> as "TxA") that indicate a future transmission of a communication and/or reception (Rx) announcements (shown in <FIG> as "RxA") that indicate a future reception of a communication. TxAs and RxAs may indicate the resources that will be used for the future communication.

For example, a transmission announcement may indicate a set of resources reserved for a future transmission of a communication. In some cases, a transmission announcement may be transmitted using a beam to be used to transmit the transmission that is indicated by the transmission announcement. In some cases, the transmission announcement may be transmitted using a beam that is wider than the beam to be used to transmit the transmission indicated by the transmission announcement. In this case, the transmission announcement may be used to facilitate preventing a WCD within the coverage area from using resources, in a direction overlapped by the coverage area, that overlap resources used by the WCD <NUM> to transmit the future communication. In some cases, the transmission announcement may be transmitted as part of SCI. A nearby WCD can receive the transmission announcement and, in response to receiving the transmission announcement, can select resources and/or beams that do not overlap those indicated in the announcement.

For example, as shown in <FIG>, the WCD <NUM> may intend, at least initially, to transmit and/or receive a communication using the beam <NUM>, which may have a coverage area that overlaps the coverage area of the beam <NUM>. The WCD <NUM> may receive the transmission announcement and, in response to receiving the transmission announcement, may avoid communicating on the beam <NUM> (as indicated by the "X" over the beam <NUM>). In some cases, the WCD <NUM> may avoid communicating using resources indicated in the transmission announcement.

In some cases, the WCD <NUM> may provide a resource recommendation to another WCD (e.g., WCD <NUM>) that is based at least in part on the transmission announcement. For example, as shown in <FIG>, the WCD <NUM> may be receiving using a beam <NUM> that is directed away from the beam <NUM> on which the transmission announcement is transmitted. As such, the WCD <NUM> may not receive the transmission announcement. However, the WCD <NUM> may transmit a resource recommendation to the WCD <NUM> that indicates the resource information provided in the transmission announcement and/or that suggests resources for the WCD <NUM> to use that avoid interference with the future communication.

In some cases, to facilitate reception of relevant transmission announcements, a WCD (e.g., WCD <NUM>) may monitor for transmission announcements using a beam that the WCD intends to use to transmit or receive a communication. In some cases, to further facilitate avoidance of interference, a WCD that intends to receive a communication may monitor for transmission announcements. Similarly, a WCD that intends to transmit a communication may monitor for reception announcements.

<FIG> is a diagram illustrating an example <NUM> of communications in a network, in accordance with various aspects of the present disclosure. As shown, a first wireless communication device (WCD <NUM>), a second wireless communication device (WCD <NUM>), a third wireless communication device (WCD <NUM>), and a fourth wireless communication device (WCD <NUM>) may communicate in a network. The network may be any type of network in which devices may communicate with other devices using beamforming techniques. For example, the network may be a millimeter wave network. In some cases, the network may be a sidelink network and/or an IAB network, among other examples. In some aspects, one or more of the WCDs may be, include, or be included in a UE, a base station, and/or an IAB node. In some cases, the WCDs may be the WCDs depicted in <FIG>.

The WCD <NUM> may be scheduled to receive a first future communication from WCD <NUM> using a beam <NUM>. The beam <NUM> may include an expanding coverage area (e.g., beam width) indicated by the area inside the two dashed arrows in <FIG>. Other WCDs may be scheduled to transmit and/or receive future communications using beams within the coverage area of the beam <NUM>.

For example, as indicated in <FIG>, the WCD <NUM> may intend to transmit a second future communication. The WCD <NUM> and/or the device that is receiving that second future communication from the WCD <NUM> may be configured to select resources to mitigate and/or minimize interference between the first and second future communications. To facilitate avoidance of interference, WCDs may transmit announcements that indicate future communications. In some aspects, for example, a reception announcement (shown as "RxA") may indicate a set of resources reserved for a future reception of a communication. In some cases, a reception announcement may be received using a beam to be used to receive the communication that is indicated by the reception announcement. In some cases, the reception announcement may be transmitted using a beam that is wider than the beam to be used to receive the communication indicated by the reception announcement. In this case, the reception announcement may be used to facilitate preventing a WCD within the coverage area from using resources, in a direction overlapped by the coverage area, that overlap resources used by the WCD <NUM> to receive the future communication. In some cases, the reception announcement may be transmitted as part of a PSFCH or similar channel. A nearby WCD can receive the reception announcement and, in response to receiving the reception announcement, can select resources and/or beams that do not overlap those indicated in the announcement.

For example, as shown in <FIG>, the WCD <NUM> may intend, at least initially, to transmit and/or receive a communication using the beam <NUM>, which may have a coverage area that overlaps the coverage area of the beam <NUM>. The WCD <NUM> may receive the reception announcement and, in response to receiving the reception announcement, may avoid communicating on the beam <NUM> (as indicated by the "X" over the beam <NUM>). In some cases, the WCD <NUM> may avoid communicating using resources indicated in the reception announcement.

In some cases, the WCD <NUM> may provide a resource recommendation to another WCD (e.g., WCD <NUM>) that is based at least in part on the reception announcement. For example, as shown in <FIG>, the WCD <NUM> may be receiving using a beam <NUM> that is directed away from the beam <NUM> on which the reception announcement is transmitted. As such, the WCD <NUM> may not receive the reception announcement. However, the WCD <NUM> may transmit a resource recommendation to the WCD <NUM> that indicates the resource information provided in the reception announcement and/or that suggests resources for the WCD <NUM> to use that avoid interference with the future communication. In some cases, to facilitate reception of relevant reception announcements, a WCD (e.g., WCD <NUM>) may monitor for reception announcements using a beam that the WCD intends to use to transmit or receive a communication.

In some cases, a transmission announcement and/or reception announcement may not be received by WCDs that should receive them (e.g., WCDs that are scheduled to transmit and/or receive future communications that may interfere with a future communication transmitted and/or received by a WCD). Failure to receive such announcements or receiving announcements that are no longer valid (e.g., due to preemption and/or cancellation of the corresponding communications) may lead to increased instances of interference between communications on a network or avoidance of network resources that are not otherwise being used, thereby reducing network throughput and efficiency, and otherwise decreasing network performance.

Aspects of the techniques and apparatuses described herein may provide configurable announcements in a network. For example, some aspects may include persistent announcements that may be transmitted with some periodicity. In some aspects, a transmission announcement may be configured to indicate a plurality of future resource reservations and/or communications corresponding thereto. For example, the transmission announcement may be configured to indicate four or more future reservations. In some aspects, a reception reservation may be configured to indicate a plurality of future reservations, thereby facilitating more efficient use of network resources.

In some aspects, an announcement may be transmitted multiple times. In some aspects, a first set of announcements (which may be repetitions of the same announcement) is transmitted according to a first transmission frequency (rate at which the announcements are transmitted - e.g., an inverse of the time period between each transmission). A second set of announcements is transmitted according to a second transmission frequency. In some aspects, the second transmission frequency may be higher than the first frequency so that announcements are transmitted more frequently as the time for the future communication gets closer. In this way, the number of announcement transmissions may be limited when the time for the future communication is farther away, thereby facilitating more efficient use of network resources.

In some aspects, an announcement may indicate a future communication that is cancelled or preempted before the time for the future communication occurs. In some aspects, a wireless communication device may transmit an announcement that indicates the communication and, at a later time, may transmit a cancellation indication (that indicates a cancellation of the communication) and/or a preemption indication (that indicates a preemption of the resources reserved for the communication). In this way, some aspects may facilitate notifying nearby wireless communication devices of a change in a planned future communication. As a result, some aspects may facilitate increased efficiency of network resource use, throughput, and/or overall network performance.

<FIG> is a diagram illustrating an example <NUM> associated with persistent announcements in a network, in accordance with various aspects of the present disclosure. As shown, a first WCD <NUM>, a second WCD <NUM>, and a third WCD <NUM> may communicate in a network. The network may be any type of network in which devices may communicate with other devices using beamforming techniques. For example, the network may be a millimeter wave network. In some cases, the network may be a sidelink network and/or an IAB network, among other examples. In some aspects, one or more of the WCDs <NUM>, <NUM>, and <NUM> may be, include, or be included in a UE, a base station, and/or an IAB node.

As shown by reference number <NUM>, the WCD <NUM> may transmit, and the WCD <NUM> may receive, a first set of announcements. The first set of announcements includes one or more transmission announcements or reception announcements. In some aspects, the first set of announcements includes a transmission or reception announcement. In some aspects, the announcement indicates one or more future reservations. In some aspects, for example, an announcement may indicate one, two, three, four, or more future resource reservations corresponding to a future communication or communications. The announcement or announcements may include transmission announcements and/or reception announcements.

In some aspects, the WCD <NUM> transmits the first set of announcements during a first time period and using a first transmission frequency. The first transmission frequency may be a frequency of transmission associated with a periodicity. A periodicity refers to the amount of time between transmissions. A short periodicity refers to a small amount of time between transmissions and, as such, may correspond to more transmissions occurring within a certain amount of time than the number of transmissions during that same amount of time corresponding to a long periodicity. In some aspects, the first set of announcements may be transmitted with a long periodicity. The first set of announcements is associated with a plurality of future resource reservations, where a first resource reservation of the plurality of resource reservations corresponds to a scheduled time.

As shown by reference number <NUM>, the WCD <NUM> transmits, and the WCD <NUM> may receive, a second set of announcements associated with the plurality of future resource reservations. The second set of announcements is transmitted during a second time period and/or using a second transmission frequency that is different than the first transmission frequency. In some aspects, for example, the second transmission frequency may be greater than the first transmission frequency. As a result, the periodicity associated with the second set of announcements may be shorter than the periodicity associated with the first set of announcements.

In some aspects, the transmission frequency may be based at least in part on a distance of a transmission of an announcement from the first future communication in time. In this way, announcements may be transmitted with greater frequency as the time for the future communication approaches, increasing chances that devices will receive the announcements. As a result, aspects of this dynamically changing transmission frequency also may facilitate reducing communication resource consumption for notifying of communications that are not imminent.

As shown by reference number <NUM>, the WCD <NUM> may transmit, and the WCD <NUM> may receive, an announcement change indication. The announcement change indication may include a cancellation indication and/or a preemption indication, among other examples. In some aspects, the announcement change indication may be transmitted to WCD <NUM> (with which the future communication is scheduled) to alert the WCD <NUM> of the change.

A cancellation indication may indicate that one or more future resource reservations are cancelled. In some aspects, the cancellation indication may include an identifier associated with the one or more future resource reservations. In this way, the WCD <NUM> may be able to identify the future reservation that has been canceled and may schedule another future communication using the resources that are available as a result of the cancellation. The cancellation indication may include the announcement corresponding to the canceled reservation to facilitate identifying the resources that have become available (e.g., so that, even if the WCD <NUM> did not store an indication of the future reservation, the WCD <NUM> may ascertain available resources). In some aspects, the identifier may include a UE identifier corresponding to the wireless communication device <NUM>.

In some aspects, the WCD <NUM> may transmit the cancellation announcement using a beam that is wider than the beam associated with the transmission of the corresponding announcement. For example, the WCD <NUM> may transmit the announcement using a beam having a first beam width and may transmit the cancellation indication using a beam having a second beam width, where the second beam width is larger than the first beam width. In this way, aspects may facilitate increasing the chance that more devices receive the cancellation indication. As a result, aspects may facilitate preventing unnecessary avoidance of otherwise-available resources and/or account for movement of devices and the monitoring of other beams by devices.

In some aspects, the WCD <NUM> may repeat cancellation indication transmissions to further facilitate avoidance of resource waste. Repetition of cancellation indications may be dependent upon reservation size. For example, the WCD <NUM> may determine that a size of the one or more resource reservations satisfies a cancellation threshold and transmit an additional cancellation indication (or a plurality of additional cancellation indications) corresponding to the reception announcement based at least in part on determining that the size of the one or more resource reservations satisfies the cancellation threshold. In this way, avoidance of waste of large resource reservations may be enhanced.

In some aspects, as indicated above, the change indication may include a preemption indication. A preemption indication may indicate that one or more future resource reservations of the plurality of future reservations are preempted. In some aspects, as shown by reference number <NUM>, the preemption indication may be transmitted to the WCD <NUM> to indicate to WCD <NUM> that future communication between the WCD <NUM> and the WCD <NUM> is no longer to occur using the reserved resources, as those resources have been preempted for a communication with another WCD. Since the resources are still reserved, there may be no value in transmitting the preemption indication to other devices. From the perspective of other devices, the reserved resources are still unavailable and/or subject to interference.

In some aspects, however, the preemption indication may be transmitted to other WCDs (e.g., WCD <NUM>). For example, in some aspects, the preempting communication may be scheduled to use a different beam than the beam associated with the future communication. In this case, the possibility of interference from using the same or overlapping resources on a different beam may be reduced, in which case the WCD <NUM> may determine that the resources are available for a communication. In some aspects, the preemption indication may indicate a reason for preemption of the one or more future resource reservations. For example, the preemption indication may indicate that a set of resources associated with the one or more future resource reservations will be used by another wireless communication device.

As shown by reference number <NUM>, the WCD <NUM> may engage in future communications with the WCD <NUM>. In some aspects, the WCD <NUM> transmits a future communication to the WCD <NUM>. In some aspects, the WCD <NUM> receives a future communication from at least one communication from an additional wireless communication device using at least one of the plurality of future resource reservations.

<FIG> is a diagram illustrating an example <NUM> associated with persistent announcements in a network, in accordance with various aspects of the present disclosure. As shown in <FIG>, a first WCD <NUM> may communicate with a second WCD <NUM>. In some aspects, the WCD <NUM> may be, be similar to, be included in, or include, the WCD <NUM> shown in <FIG> and the WCD <NUM> may be, be similar to, be included in, or include the WCD <NUM> shown in <FIG>.

As shown by reference number <NUM>, the WCD <NUM> transmits an announcement to the WCD <NUM>. The announcement includes one or more reception announcements (RxAs) used to indicate one or more future resource reservations corresponding to one or more future communications (receptions, Rxs, in the illustrated examples). In some aspects, transmission announcements (TxAs) are used to indicate one or more future resource reservations corresponding to one or more future transmission communications.

As shown by reference number <NUM>, a single reception announcement (RxA) may indicate a plurality of resource reservations for communication receptions (Rxs). In the illustrated example, the reception announcement may indicate four future reception communications. In some aspects, the reception announcement may indicate more than four future reception communications or less than four future reception communications.

As shown by reference number <NUM>, multiple reception announcements may be used to indicate a future resource reservation and a transmission frequency may be based at least on a time between an announcement and a resource reservation. For example, as shown, the WCD <NUM> may transmit a first set <NUM> of reception announcements and a second set <NUM> of reception announcements. The WCD <NUM> may transmit the first set <NUM> of reception announcements using a first transmission frequency that may correspond to a first periodicity <NUM>. The WCD <NUM> may transmit the second set <NUM> of reception announcements using a second transmission frequency that may correspond to a second periodicity <NUM> that is shorter than the first periodicity <NUM>.

The WCD <NUM> may change the transmission frequency from the first frequency to the second frequency based at least in part on a distance (amount of time) between an announcement and the resource reservation and/or a distance between a current time and the resource reservation, among other examples. For example, the WCD <NUM> may determine a distance between a current time and the time of the resource reservation and compare the determined distance to a distance threshold. The WCD <NUM> may select a transmission frequency based at least in part on whether the distance satisfies the distance threshold.
