Patent Description:
Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE).

A wireless network may include one or more base stations that support communication for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. "Downlink" (or "DL") refers to a communication link from the base station to the UE, and "uplink" (or "UL") refers to a communication link from the UE to the base station.

The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as <NUM>, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

<CIT> discloses a user equipment that may determine an automatic gain control parameter, for a group of downlink symbols associated with a base station, based at least in part on an automatic gain control resource included in the group of downlink symbols. The user equipment may perform, based at least in part on the automatic gain control parameter, automatic gain control for one or more data symbols included in the group of downlink symbols.

<CIT> discloses a UE that may select, from a plurality of short transmission time intervals (TTIs), a short TTI for a vehicle-to-vehicle (V2V) sidelink transmission by the UE. The short TTIs may occur within a legacy TTI. The short TTIs may be allocated for V2V sidelink transmissions by non-legacy UEs. The legacy TTI may be allocated for V2V sidelink transmissions by legacy UEs. The UE may transmit, in accordance with the legacy TTI, a legacy physical sidelink control channel (PSCCH) to indicate, to legacy UEs, the V2V sidelink transmission by the UE.

<CIT> discloses a receiver of a communication system that includes means for receiving repetition-coded data. The receiver also includes means for generating symbol information from the received repetition-coded data, means for storing symbol information over a predetermined period and means for making tentative symbol decisions by combining the stored symbol information.

It is intended that aspects described herein may be practiced in a wide variety of devices, components, systems, distributed arrangements, and/or end-user devices of varying size, shape, and constitution.

One skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure.

While aspects may be described herein using terminology commonly associated with a <NUM> or New Radio (NR) radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a <NUM> RAT, a <NUM> RAT, and/or a RAT subsequent to <NUM> (e.g., <NUM>).

The wireless network <NUM> may be or may include elements of a <NUM> (e.g., NR) network and/or a <NUM> (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network <NUM> may include one or more base stations <NUM> (shown as a BS 110a, a BS 110b, a BS 110c, and a BS 110d), a user equipment (UE) <NUM> or multiple UEs <NUM> (shown as a UE 120a, a UE 120b, a UE 120c, a UE 120d, and a UE 120e), and/or other network entities. A base station <NUM> is an entity that communicates with UEs <NUM>. A base station <NUM> (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in <NUM>), a gNB (e.g., in <NUM>), an access point, and/or a transmission reception point (TRP). Each base station <NUM> may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" can refer to a coverage area of a base station <NUM> and/or a base station subsystem serving this coverage area, depending on the context in which the term is used.

A base station <NUM> may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs <NUM> with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs <NUM> with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs <NUM> having association with the femto cell (e.g., UEs <NUM> in a closed subscriber group (CSG)). A base station <NUM> for a macro cell may be referred to as a macro base station. A base station <NUM> for a pico cell may be referred to as a pico base station. A base station <NUM> for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown in <FIG>, the BS 110a may be a macro base station for a macro cell 102a, the BS 110b may be a pico base station for a pico cell 102b, and the BS 110c may be a femto base station for a femto cell 102c. A base station may support one or multiple (e.g., three) cells.

In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a base station <NUM> that is mobile (e.g., a mobile base station). In some examples, the base stations <NUM> may be interconnected to one another and/or to one or more other base stations <NUM> or network nodes (not shown) in the wireless network <NUM> through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network.

The wireless network <NUM> may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station <NUM> or a UE <NUM>) and send a transmission of the data to a downstream station (e.g., a UE <NUM> or a base station <NUM>). A relay station may be a UE <NUM> that can relay transmissions for other UEs <NUM>. In the example shown in <FIG>, the BS 110d (e.g., a relay base station) may communicate with the BS 110a (e.g., a macro base station) and the UE 120d in order to facilitate communication between the BS 110a and the UE 120d. A base station <NUM> that relays communications may be referred to as a relay station, a relay base station, a relay, or the like.

The wireless network <NUM> may be a heterogeneous network that includes base stations <NUM> of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, or the like. These different types of base stations <NUM> may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network <NUM>. For example, macro base stations may have a high transmit power level (e.g., <NUM> to <NUM> watts) whereas pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., <NUM> to <NUM> watts).

A network controller <NUM> may couple to or communicate with a set of base stations <NUM> and may provide coordination and control for these base stations <NUM>. The network controller <NUM> may communicate with the base stations <NUM> via a backhaul communication link. The base stations <NUM> may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link.

The UEs <NUM> may be dispersed throughout the wireless network <NUM>, and each UE <NUM> may be stationary or mobile. A UE <NUM> may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE <NUM> may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, and/or any other suitable device that is configured to communicate via a wireless medium.

Some UEs <NUM> may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs <NUM> may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs <NUM> may be considered a Customer Premises Equipment. A UE <NUM> may be included inside a housing that houses components of the UE <NUM>, such as processor components and/or memory components. The processor components and the memory components are coupled together.

In general, any number of wireless networks <NUM> may be deployed in a given geographic area. Each wireless network <NUM> may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like.

In some examples, two or more UEs <NUM> (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using a base station <NUM> as an intermediary to communicate with one another). For example, the UEs <NUM> may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE <NUM> may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station <NUM>.

Devices of the wireless network <NUM> may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network <NUM> may communicate using one or more operating bands. In <NUM> NR, two initial operating bands have been identified as frequency range designations FR1 (<NUM> - <NUM>) and FR2 (<NUM> - <NUM>). It should be understood that although a portion of FR1 is greater than <NUM>, FR1 is often referred to (interchangeably) as a "Sub-<NUM>" band in various documents and articles.

With the above examples in mind, unless specifically stated otherwise, it should be understood that the term "sub-<NUM>" or the like, if used herein, may broadly represent frequencies that may be less than <NUM>, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term "millimeter wave" or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-<NUM>, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-<NUM>, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges.

In some aspects, the UE <NUM> may include a communication manager <NUM>. As described in more detail elsewhere herein, the communication manager <NUM> receives an indication of a quantity of a first set of symbols for a slot; and receive data in the first set of symbols and a second set of symbols in the slot, wherein the first set of symbols repeat data included in one or more symbols of the second set of symbols. Additionally, or alternatively, the communication manager <NUM> may perform one or more other operations described herein.

In some aspects, as described in more detail elsewhere herein, the communication manager <NUM> may transmit, to a second UE, an indication of a quantity of a first set of symbols for a slot; and transmit, to the second UE, data in the first set of symbols and a second set of symbols in the slot, wherein the first set of symbols repeat data included in one or more symbols of the second set of symbols. Additionally, or alternatively, the communication manager <NUM> may perform one or more other operations described herein.

In some aspects, the base station <NUM> may include a communication manager <NUM>.

Additionally, or alternatively, the communication manager <NUM> may perform one or more other operations described herein.

The base station <NUM> may be equipped with a set of antennas 234a through 234t, such as T antennas (T ≥ <NUM>). The UE <NUM> may be equipped with a set of antennas 252a through 252r, such as R antennas (R ≥ <NUM>).

At the base station <NUM>, a transmit processor <NUM> may receive data, from a data source <NUM>, intended for the UE <NUM> (or a set of UEs <NUM>). The transmit processor <NUM> may select one or more modulation and coding schemes (MCSs) for the UE <NUM> based at least in part on one or more channel quality indicators (CQIs) received from that UE <NUM>. The base station <NUM> may process (e.g., encode and modulate) the data for the UE <NUM> based at least in part on the MCS(s) selected for the UE <NUM> and may provide data symbols for the UE <NUM>. The transmit processor <NUM> may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor <NUM> may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor <NUM> may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems <NUM> (e.g., T modems), shown as modems 232a through 232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem <NUM>. Each modem <NUM> may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem <NUM> may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas <NUM> (e.g., T antennas), shown as antennas 234a through 234t.

At the UE <NUM>, a set of antennas <NUM> (shown as antennas 252a through 252r) may receive the downlink signals from the base station <NUM> and/or other base stations <NUM> and may provide a set of received signals (e.g., R received signals) to a set of modems <NUM> (e.g., R modems), shown as modems 254a through 254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem <NUM>. Each modem <NUM> may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem <NUM> may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector <NUM> may obtain received symbols from the modems <NUM>, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor <NUM> may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE <NUM> to a data sink <NUM>, and may provide decoded control information and system information to a controller/processor <NUM>. In some examples, one or more components of the UE <NUM> may be included in a housing <NUM>.

The network controller <NUM> may include a communication unit <NUM>, a controller/processor <NUM>, and a memory <NUM>. The network controller <NUM> may include, for example, one or more devices in a core network. The network controller <NUM> may communicate with the base station <NUM> via the communication unit <NUM>.

One or more antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of <FIG>.

On the uplink, at the UE <NUM>, a transmit processor <NUM> may receive and process data from a data source <NUM> and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from the controller/processor <NUM>. The transmit processor <NUM> may generate reference symbols for one or more reference signals. The symbols from the transmit processor <NUM> may be precoded by a TX MIMO processor <NUM> if applicable, further processed by the modems <NUM> (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station <NUM>. In some examples, the modem <NUM> of the UE <NUM> may include a modulator and a demodulator. In some examples, the UE <NUM> includes a transceiver. The transceiver may include any combination of the antenna(s) <NUM>, the modem(s) <NUM>, the MIMO detector <NUM>, the receive processor <NUM>, the transmit processor <NUM>, and/or the TX MIMO processor <NUM>. The transceiver may be used by a processor (e.g., the controller/processor <NUM>) and the memory <NUM> to perform aspects of any of the methods described herein (e.g., with reference to <FIG>).

At the base station <NUM>, the uplink signals from UE <NUM> and/or other UEs may be received by the antennas <NUM>, processed by the modem <NUM> (e.g., a demodulator component, shown as DEMOD, of the modem <NUM>), detected by a MIMO detector <NUM> if applicable, and further processed by a receive processor <NUM> to obtain decoded data and control information sent by the UE <NUM>. The receive processor <NUM> may provide the decoded data to a data sink <NUM> and provide the decoded control information to the controller/processor <NUM>. The base station <NUM> may include a communication unit <NUM> and may communicate with the network controller <NUM> via the communication unit <NUM>.

The controller/processor <NUM> of the base station <NUM>, the controller/processor <NUM> of the UE <NUM>, and/or any other component(s) of <FIG> may perform one or more techniques associated with within slot repetition for improved coverage, energy harvesting, and/or automatic gain control (AGC), as described in more detail elsewhere herein.

In some examples, the memory <NUM> and/or the 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>, and/or other processes as described herein.

<FIG> is a diagram illustrating examples <NUM> of radio frequency (RF) energy harvesting, in accordance with the present disclosure. As shown in <FIG>, an RF receiver (e.g., a UE <NUM>) may receive signals (e.g., radio signals carried on radio waves) from an RF transmitter (e.g., a base station <NUM> or a UE <NUM>) and convert electromagnetic energy of the signals (e.g., using a rectenna comprising a dipole antenna with an RF diode) into direct current electricity for use by the RF receiver.

As shown by reference number <NUM>, in some aspects, the RF receiver may use a separated receiver architecture, where a first set of antennas is configured to harvest energy, and a second set of antennas is configured to receive data. In this situation, each set of antennas may be separately configured to receive signals at certain times, frequencies, and/or via one or more particular beams, such that all signals received by the first set of antennas are harvested for energy by an energy harvester (e.g., an energy harvester circuit), and all signals received by the second set of antennas are processed to receive information by an information receiver (e.g., an information receiver/decoder circuit).

As shown by reference number <NUM>, in some aspects, the RF receiver may use a time-switching architecture to harvest energy. The time-switching architecture allows the RF receiver to switch between an energy harvester that harvests energy from received signals and an information receiver that decodes received signals to receive information. The time-switching architecture may use one or more antennas to receive signals, and whether the signals are harvested for energy or processed to receive information depends on the time at which the signals are received. For example, one or more first time slots may be time slots during which received signals are sent to one or more energy harvesting components (e.g., the energy harvester) to harvest energy, and one or more second time slots may be time slots during which received signals are processed and decoded (e.g., by the information receiver) to receive information. In some aspects, the time slots may be pre-configured (e.g., by the RF receiver, the RF transmitter, or another device). The energy harvested at receiver j from source i may be calculated as Ej = ηPi|gi-j|<NUM>αT, where <NUM> ≤ α ≤ <NUM> is a fraction of a total time period T allocated for energy harvesting, Pi is a transmit power, |gi-j|<NUM> is a channel power gain, and η (e.g., <NUM> ≤ η ≤ <NUM>) is an energy harvesting efficiency. Letting κ and W denote a noise spectral density and a channel bandwidth, respectively, the data rate for the time-switching architecture may be calculated as <MAT>.

As shown by reference number <NUM>, in some aspects, the RF receiver may use a power-splitting architecture to harvest energy. The power-splitting architecture may use one or more antennas to receive signals, and the signals are handled by one or both of the energy harvesting and/or information receiving components according to an energy harvesting rate. The received signals may be split into two streams (e.g., one for the energy harvester and another for the information receiver) with different power levels. For example, the RF receiver may be configured to use a first portion of received signals for energy harvesting and the remaining received signals for information receiving. The energy harvesting rate is dependent on (e.g., a fraction of) power of a received signal that is allocated for energy harvesting. In some aspects, the energy harvesting rate may be pre-configured (e.g., by the RF receiver, the RF transmitter, or another device). The energy harvested at receiver j from source i may be calculated as Ej = ηρPi|gi-j|<NUM>T, where <NUM> ≤ ρ ≤ <NUM> is the energy harvesting rate (e.g., the fraction of the power allocated for energy harvesting). The data rate for the power-splitting architecture may be calculated as <MAT>.

Energy harvested by the RF receiver may be used and/or stored for later use. For example, in some aspects, the RF receiver may be powered directly by the harvested energy. In some aspects, the RF receiver may use an energy storage device, such as a battery, capacitor, and/or supercapacitor, to gather and store harvested energy for immediate and/or later use.

As indicated above, <FIG> is provided as one or more examples.

Energy harvesting may be used to prolong the battery life of UEs (e.g., including sidelink UEs, such as wearable devices, among other examples). Furthermore, energy harvesting may be used to provide incentives (e.g., signals for energy harvesting) in exchange for cooperation by UEs, such as relaying signals for other UEs. However, in some cases, energy harvesting may adversely affect a data rate of traffic received by a UE.

Some techniques and apparatuses described herein enable a portion of a downlink (e.g., a physical shared downlink channel (PDSCH)) signal or a portion of a sidelink (e.g., a physical shared sidelink channel (PSSCH)) signal to be repeated within a slot. In particular, a UE receives (e.g., from a base station or another UE) an indication of a quantity of a first set symbols for a slot. The UE receives data in the first set of symbols and a second set of symbols in the slot. The first set of symbols includes repetition of data included in one or more symbols in the second set of symbols. For example, a transport block may be included in the second set of symbols in the slot, and the first set of symbols may repeat of one or more symbols in the second set of symbols. In some aspects, the UE may perform energy harvesting using the first set of symbols. Because the first set of symbols are repetitions of symbols in the second set of symbols, the UE may perform energy harvesting in the slot, while still receiving the data transmitted in the slot. As a result, the battery life of the UE may be prolonged, without delaying traffic transmitted to the UE. In some aspects, the UE may perform combined decoding of one or more of the symbols in the second set of symbols and the first set of symbols. As a result, the decoding of the symbols may be improved, resulting in improved coverage for the UE. In some aspects, the UE may perform AGC using all or a portion of the first set of symbols, which may result in improved AGC for a sidelink communication.

<FIG> is a diagram illustrating an example <NUM> associated with within slot repetition for improved coverage, energy harvesting, and/or AGC, in accordance with the present disclosure. As shown in <FIG>, example <NUM> includes communication between a base station <NUM> and a UE <NUM>. In some aspects, the base station <NUM> and the UE <NUM> may be included in a wireless network, such as wireless network <NUM>. The base station <NUM> and the UE <NUM> may communicate via a wireless access link, which may include an uplink and a downlink.

As shown in <FIG>, and by reference number <NUM>, in some aspects, the UE <NUM> may transmit, to the base station <NUM>, an indication of a requested quantity of repetition symbols for a slot. "Repetition symbols" refers to one or more symbols in a slot that are used to transmit repeated data that is also transmitted using one or more of the remaining symbols in the slot. The repetition symbols in a slot may also be referred to as a first set of symbols in the slot, and the remaining symbols in the slot may be referred to as a second set of symbols in the slot. In some aspects, the second set of symbols may be allocated for transmitting a transport block to the UE <NUM>, and the first set of symbols may include repetitions of data signals included in at least a subset of the second set of symbols. In some aspects, the UE <NUM> may use the repetition symbols in a downlink communication for energy harvesting and/or combined decoding of one or more symbols of the transport block. In some aspects, the UE <NUM> may use the repetition symbols in a sidelink communication for energy harvesting, combined decoding of one or more symbols of the transport block, and/or AGC.

In some aspects, the UE <NUM> may transmit, to the base station <NUM>, an indication of a requested or recommended quantity of repetition symbols to be included in a slot. For example, the UE <NUM> may determine the requested quantity of repetition symbols based at least in part on energy harvesting needs (e.g., a battery life) of the UE <NUM>. In some aspects, the UE <NUM> may transmit, to the base station <NUM>, a requested or recommended repetition pattern for the repetition symbols. The repetition pattern may indicate which one or more symbols of the second set of symbols are repeated in the first set of symbols (e.g., the repetition symbols). For example, if X denotes the quantity of the first set of symbols (e.g., the repetition symbols) in a slot and Y denotes the quantity of the second set of symbols in a slot, the repetition pattern may indicate X symbols of the Y symbols in the second set of symbols that are repeated in the first set of symbols. As used herein, a symbol in the set of symbols is "repeated" in the first set of symbols if the same data is transmitted on a symbol in the first set of symbols as on the symbol in the second set of symbols.

In some aspects, the UE <NUM> may provide separate indications of the requested quantity of the repetition symbols and the requested repetition pattern. In some aspects, the indication of the requested repetition pattern may also provide the indication of the requested quantity of the repetition symbols. In some aspects, the UE <NUM> may be configured with multiple quantity and/or repetition pattern options for the repetition symbols. In this case, the UE <NUM> may request a quantity and/or repetition pattern option from the configured options, and the UE <NUM> may transmit, to the base station <NUM>, an indication of the requested quantity and/or repetition option. For example, the indication may include an index value associated with the requested quantity and/or repetition option. In some aspects, the indication of the requested repetition pattern may include a bitmap that indicates the request for which symbols in the second set of symbols are repeated in the first set of symbols. For example, the bitmap may be a bitmap of size Y that indicates X symbols requested to be repeated of the Y symbols in the second set of symbols.

In some aspects, the first set of symbols (e.g., the repetition symbols) are configured to be transmitted in a certain location within a slot. For example, in some aspects, in a downlink communication that includes X repetition symbols, the repetition symbols may be transmitted in the first occurring X PDSCH symbols in the slot. In some aspects, the base station <NUM> may select a location to transmit the first set of symbols (e.g., the repetition symbols) in a slot. For example, for a downlink communication, the base station <NUM> may select whether to transmit the repetition symbols in the first X PDSCH symbols of the slot or in the last X PDSCH symbols in the slot. In this case, the UE <NUM> may transmit, to the base station <NUM>, an indication of a requested or recommended location for the repetition symbols in the slot. For example, the UE <NUM> may request that the repetition symbols be transmitted at the beginning of the slot (e.g., in the first X symbols), at the end of the slot (e.g., in the last X symbols), or at another location in the slot.

As further shown in <FIG>, and by reference number <NUM>, the base station <NUM> may transmit, to the UE <NUM>, an indication of a quantity (X) of repetition symbols for a slot. The base station <NUM> may select the quantity of repetition symbols (e.g., a quantity of the first set of symbols) to be included in a slot, and the base station <NUM> may transmit, to the UE <NUM>, an indication of the quantity of repetition symbols to be included in the slot.

In some aspects, the repetition signals (e.g., the first set of symbols) may be configured to be transmitted at a certain location within the slot, such as at the beginning of the slot. For example, for a downlink communication, the first set of symbols (e.g., the repetition symbols) may be the first X PDSCH symbols occurring in the slot, and the first set of symbols may be followed by the second set of symbols, which may include the Y remaining PDSCH symbols in the slot. In some aspects, a default repetition pattern may be configured for the first set of symbols. For example, the X symbols in the first set of symbols may be respective repetitions (e.g., be used to transmit the same data) as the first X symbols of the Y symbols in the second set of symbols. In this case, the indication of X (e.g., the quantity of the first set of symbols) may indicate, to the UE <NUM>, that the first X PDSCH symbols in the slot are the repetition symbols that repeat the first X symbols of the remaining Y PDSCH symbols in the slot.

In some aspects, the indication, transmitted by the base station <NUM> to the UE <NUM>, may include an indication of the repetition pattern for the first set of symbols. The repetition pattern may indicate which of the second set of symbols are repeated in the first set of symbols. For example, the repetition pattern may indicate X symbols of the Y symbols in the second set of symbols that are repeated in the first set of symbols. In some aspects, the UE <NUM> may provide separate indications of the quantity of the first set of symbols and the repetition pattern for the first set of symbols. In some aspects, the indication of the repetition pattern for the first set of symbols may provide the indication of the quantity of the first set of symbols. In some aspects, the indication of the repetition pattern may include a bitmap that indicates which symbols in the second set of symbols are repeated in the first set of symbols. For example, the bitmap may be a bitmap of size Y that indicates X symbols to be repeated of the Y symbols in the second set of symbols. In this case, the bitmap may include a respective value for each of the Y symbols of the second set of symbols. A first value (e.g., <NUM>) for a symbol in the second set of symbols may indicate that the symbol is not repeated in the first set of symbols, and a second value (e.g., <NUM>) for a symbol in the second set of symbols may indicate that the symbol is repeated in the first set of symbols. In some aspects, the indication, transmitted by the base station <NUM>, may include an indication of a selected quantity and/or repetition pattern option from a plurality of configured quantity and/or repetition pattern options. For example, the indication may include an index value associated with the selected quantity and/or repetition option.

In some aspects, the base station <NUM> may select a location of the first set of symbols (e.g., the repetition symbols) in the slot. For example, the base station <NUM> may select whether the first set of symbols are transmitted at the beginning of the slot (e.g., the first XPDSCH symbols in the slot), at the end of the slot (e.g., the last X PDSCH symbols in the slot), or at another location in the slot. In this case, the base station <NUM> may transmit, to the UE <NUM>, an indication of the location of the first set of symbols in the slot.

In some aspects, the base station <NUM> may use zero power channel state information reference signals (ZP-CSI-RSs) to indicate the quantity and/or location of the first set of symbols in the slot. For example, the base station <NUM> may transmit, to the UE <NUM>, a configuration of a respective ZP-CSI-RS on each of the X symbols in the first set of symbols. In this case, the base station <NUM> may also provide an indication that activates or enables a within slot PDSCH repetition mode or feature for the UE <NUM>. The UE <NUM>, in connection with the within slot PDSCH repetition mode or feature being enabled/activated, may understand that the ZP-CSI-RSs indicate X repetition symbols that may be used, by the UE <NUM>, for energy harvesting and/or combined decoding.

In some aspects, the quantity X of the first set of symbols (e.g., the repetition symbols) in the slot, the repetition pattern for the first set of symbols, and/or the location of the first set of symbols in the slot may be semi-statically configured, dynamically indicated, or a combination thereof. For example, the base station <NUM> may transmit, the indication of the quantity X, the repetition pattern, and/or the location of the first set of symbols in the slot in at least one of a radio resource control (RRC) message, a medium access control (MAC) control element (MAC-CE), or downlink control information (DCI) (e.g., included in a physical downlink control channel (PDCCH) communication).

In some aspects, the base station <NUM> may select the quantity X, the repetition pattern, and/or the location of first set of symbols in the slot based at least in part on the requested quantity, repetition pattern, and/or location in the slot received from the UE <NUM>. For example, the base station <NUM> may select at least one of the requested quantity, repetition pattern, or location in the slot indicated by the UE <NUM>. In some aspects, the base station <NUM> may select the quantity X, the repetition pattern, and/or the location of the first set of symbols in the slot without receiving some or all of the requested information from the UE <NUM> and/or independently from requested information received from the UE <NUM>. For example, the base station <NUM> may determine the quantity Y of the second set of symbols to transmit a transport block based at least in part on an amount of data to be transmitted to the UE <NUM>, and the base station <NUM> may select the quantity X of the first set of symbols (e.g., the quantity of repetition symbols) as the remaining quantity of PDSCH symbols in the slot.

As further shown in <FIG>, and by reference number <NUM>, the base station <NUM> may transmit, to the UE <NUM>, a downlink communication including the first set of symbols and the second set of symbols in a slot. As shown in <FIG>, the first set of symbols in the slot may include X symbols (e.g., X = <NUM> in <FIG>), and the second set of symbols in the slot may include Y symbols (e.g., Y = <NUM> in <FIG>). The base station <NUM> may transmit a PDSCH transmission including data to be decoded by the UE <NUM> in the Y symbols of the second set of symbols, and the X symbols of the first set of symbols may repeat data transmitted in one or more symbols of the second set of symbols. For example, the X symbols of the first set of symbols may repeat the data transmitted in X symbols of the Y symbols of the second set of symbols.

The UE <NUM> may receive the downlink communication including the first set of symbols and the second set of symbols. In some aspects, the UE <NUM> may perform rate-matching for PDSCH decoding across the second set of symbols. For example, the UE <NUM>, based at least in part on the indication of the quantity of the first set of symbols received from the base station <NUM>, may compute the transport block size for the downlink communication in the slot based on the Y symbols in the second set of symbols (e.g., and not based on the X symbols in the first set of symbols).

As further shown in <FIG>, and by reference number <NUM>, in some aspects, the UE <NUM> may perform energy harvesting using the first set of symbols (e.g., the repetition symbols). In some aspects, based at least in part on receiving the indication of the quantity X of the first set of symbols (e.g., the repetition symbols), the UE <NUM> may determine whether to perform energy harvesting using the first set of symbols. In some aspects, prior to performing energy harvesting, the UE <NUM> may determine whether an energy level of the UE <NUM> satisfies a threshold. Based at least in part on the threshold being satisfied, the UE <NUM> may determine to perform energy harvesting using the first set of symbols. For example, the UE <NUM> may have a low battery or may not have enough power to decode and/or transmit a response to the data included in the second set of symbols. In some aspects, the threshold may be preconfigured, for example, at a number between <NUM>% and <NUM>% of available power at the UE.

The UE <NUM> may perform energy harvesting using all or a portion of the signals received in the first set of symbols. For example, the UE <NUM> may harvest energy from all or a portion of the signals received in the first set of symbols, and the UE <NUM> may use and/or store the harvested energy from the signals received in the first set of symbols. In some aspects, the UE <NUM> may harvest energy from the signals received in all or a subset of the first set of symbols (e.g., using a time-switching architecture, as described elsewhere herein). In some aspects, the UE <NUM> may harvest energy from all or a portion of the available power in the signals received in the first set of symbols (e.g., using a power-switching architecture, as described elsewhere herein).

As further shown in <FIG>, and by reference number <NUM>, the UE <NUM> performs combined PDSCH decoding of one or more symbols in the second set of symbols using the first set of symbols (e.g., the repetition symbols). In particular, the UE <NUM> uses combined decoding for some or all of the symbols in the second set of symbols that are repeated in the first set of symbols. For a symbol in the second set of symbols that includes a same data signal as a repetition symbol in the first set of symbols, the UE <NUM> may decode the repetition symbol in the first set of symbols and the symbol in the second set of symbols, and the UE <NUM> may combine log likelihood ratios (LLRs) resulting from decoding the two symbols to obtain the repeated data included in both symbols. As a result, the UE <NUM> may improve the reliability of PDSCH decoding, which may result in improved coverage for the UE <NUM>.

Further, tthe UE <NUM> performs the combined decoding using all or a portion of the first set of symbols based at least in part on a determination not to perform energy harvesting using all or a portion of the first set of symbols. For example, the UE <NUM> may determine to perform combined decoding using the first set of symbols based at least in part on a determination that the energy level of the UE <NUM> does not satisfy the threshold for energy harvesting (e.g., a determination that energy harvesting is not currently needed by the UE <NUM>).

In some aspects, the UE <NUM> may use a first portion of the signals received in the first set of symbols for energy harvesting and a second portion of the signals received in the first set of symbols for combined decoding. In some aspects, the UE <NUM> may harvest energy from the signals received in a first subset of the first set of symbols, and the UE <NUM> may perform combined decoding using the signals received in a second subset of the first set of symbols (e.g., using a time-switching architecture, as described elsewhere herein). In some aspects, the UE <NUM> may harvest energy from a first portion of the available power in the signals received in the first set of symbols, and the UE <NUM> may use a second portion of the available power in the signals received in the first set of symbols for combined decoding with one or more of the second set of symbols (e.g., using a power-switching architecture, as described elsewhere herein).

<FIG> is a diagram illustrating an example <NUM> associated with within slot repetition for improved coverage, energy harvesting, and/or AGC, in accordance with the present disclosure. As shown in <FIG>, example <NUM> includes communication between a base station <NUM>, a first UE <NUM>-<NUM>, and a second UE <NUM>-<NUM>. In some aspects, the base station <NUM>, the first UE <NUM>-<NUM>, and the second UE <NUM>-<NUM> may be included in a wireless network, such as wireless network <NUM>. The base station <NUM> may communicate with the first UE <NUM>-<NUM> and/or the second UE <NUM>-<NUM> via a wireless access link, which may include an uplink and a downlink. The first UE <NUM>-<NUM> and the second UE <NUM>-<NUM> may communicate via a sidelink (e.g., via a PC5 interface).

In some aspects, the first UE <NUM>-<NUM> may be a transmitting (Tx) UE for one or more sidelink communications, and the second UE <NUM>-<NUM> may be a receiving (Rx) UE for the one or more sidelink communications. In some aspects, the first UE <NUM>-<NUM> (e.g., Tx UE) and/or the second UE <NUM>-<NUM> (e.g., Rx UE) may operate in a first sidelink resource allocation mode (e.g., Mode <NUM>) in which the base station <NUM> allocates resources for sidelink communications between the UEs. In some aspects, the first UE <NUM>-<NUM> (e.g., Tx UE) and/or the second UE <NUM>-<NUM> (e.g., Rx UE) may operate using a second sidelink resource allocation mode (e.g., Mode <NUM>) in which resource allocation for sidelink communication is autonomously performed by the Tx UE (e.g., the first UE <NUM>-<NUM>).

As shown in <FIG>, and by reference number <NUM>, in some aspects, the second UE <NUM>-<NUM> may transmit, to the first UE <NUM>-<NUM>, an indication of a requested quantity of repetition symbols for a slot. The repetition symbols in a slot are referred to as a first set of symbols in the slot, and a second set of symbols in the slot may include all or a portion of the remaining symbols in the slot. For example, for a sidelink communication, the first set of symbols may include a quantity of PSSCH symbols in a slot, and the second set of symbols may include the remaining PSSCH symbols in the slot. In some aspects, the second set of symbols may be allocated for transmitting a transport block to the second UE <NUM>-<NUM>, and the first set of symbols may include repetitions of data signals included in at least a subset of the second set of symbols. In some aspects, the second UE <NUM>-<NUM> may use the repetition symbols in a sidelink communication for energy harvesting, combined decoding of one or more symbols of the transport block, and/or AGC.

In some aspects, the second UE <NUM>-<NUM> may transmit, to the first UE <NUM>-<NUM>, an indication of a requested or recommended quantity of repetition symbols to be included in a slot. For example, the second UE <NUM>-<NUM> may determine the requested quantity of repetition symbols based at least in part on energy harvesting needs (e.g., a battery life) of the second UE <NUM>-<NUM>. In some aspects, the second UE <NUM>-<NUM> may transmit, to the first UE <NUM>-<NUM>, a requested or recommended repetition pattern for the repetition symbols. The repetition pattern may indicate which one or more symbols of the second set of symbols are repeated in the first set of symbols (e.g., the repetition symbols). For example, if X denotes the quantity of the first set of symbols (e.g., the repetition symbols) in a slot and Y denotes the quantity of the second set of symbols in a slot, the repetition pattern may indicate X symbols of the Y symbols in the second set of symbols that are repeated in the first set of symbols.

In some aspects, the second UE <NUM>-<NUM> may provide separate indications of the requested quantity of the repetition symbols and the requested repetition pattern. In some aspects, the indication of the requested repetition pattern may also provide the indication requested quantity of the repetition symbols. In some aspects, the base station <NUM> may configure the first UE <NUM>-<NUM> and the second UE <NUM>-<NUM> (e.g., via configuration messages transmitted from the base station <NUM>) with multiple quantity and/or repetition pattern options for the repetition symbols. In this case, the second UE <NUM>-<NUM> may request a quantity and/or repetition pattern option from the configured options, and the second UE <NUM>-<NUM> may transmit, to the first UE <NUM>-<NUM>, an indication of the requested quantity and/or repetition option. For example, the indication may include an index value associated with the requested quantity and/or repetition option. In some aspects, the indication of the requested repetition pattern may include a bitmap that indicates the request for which symbols in the second set of symbols are repeated in the first set of symbols. For example, the bitmap may be a bitmap of size Y that indicates X symbols requested to be repeated of the Y symbols in the second set of symbols.

In some aspects, the first set of symbols (e.g., the repetition symbols) are configured to be transmitted in a certain location within a slot. For example, in some aspects, in a sidelink communication that includes X repetition symbols, the repetition symbols may be transmitted at a beginning of the slot (e.g., in the first occurring X symbols after an AGC symbol in the slot). In some aspects, the first UE <NUM>-<NUM> or the base station <NUM> may select a location to transmit the first set of symbols (e.g., the repetition symbols) in a slot. For example, for a sidelink communication, the first UE <NUM>-<NUM> or the base station <NUM> may select whether to transmit the repetition symbols at the beginning of the slot (e.g., in the first occurring X symbols after an AGC symbol in the slot), the end of the slot (e.g., in the last X symbols in the slot), or another location in the slot (e.g., in the last X PSSCH symbols in the slot, prior to the gap symbols and the physical sidelink feedback channel (PSFCH) symbols). In this case, the second UE <NUM>-<NUM> may transmit, to the first UE <NUM>-<NUM>, an indication of a requested or recommended location for the repetition symbols in the slot. For example, the second UE <NUM>-<NUM> may request that the repetition symbols be transmitted at the beginning of the slot (e.g., in the first X symbols after the AGC symbol) in a case in which the second UE <NUM>-<NUM> may use one or more of the repetition symbols for performing AGC, and the second UE <NUM>-<NUM> may request that the repetition symbols be transmitted at the end of the slot (e.g., in the last X symbols), or at another location in the slot (e.g., in the last X PSSCH symbols) in a case in which the second UE <NUM>-<NUM> will not use the repetition signals for performing AGC.

In some aspects, such as in a case in which the first UE <NUM>-<NUM> is operating in Mode <NUM>, the first UE <NUM>-<NUM> may transmit, to the base station <NUM>, the indication of the requested quantity of repetition symbols, the requested repetition pattern, and/or the requested location of the repetition symbols received from the second UE <NUM>-<NUM>. In some aspects, in a case in which the second UE <NUM>-<NUM> is in a coverage area of the base station <NUM>, the second UE <NUM>-<NUM> may transmit the indication of the requested quantity, repetition pattern, and/or location of the repetition symbols to the base station <NUM>, in addition to, or instead of, to the first UE <NUM>-<NUM>.

As further shown in <FIG>, and by reference number <NUM>, the first UE <NUM>-<NUM> may transmit, to the second UE <NUM>-<NUM>, an indication of a quantity (X) of repetition symbols for a slot.

In some aspects, the repetition signals (e.g., the first set of symbols) may be configured to be transmitted at a certain location within the slot, such as at the beginning of the slot. For example, for a sidelink communication, the first set of symbols (e.g., the repetition symbols) may be the first X symbols (e.g., PSSCH symbols) after the AGC symbol in the slot, and the first set of symbols may be followed by the second set of symbols, which may include the Y remaining PSSCH symbols in the slot (e.g., including a subset of symbols that include PSSCH resources and physical sidelink control channel (PSCCH) resources). In some aspects, a default repetition pattern may be configured for the first set of symbols. For example, the X symbols in the first set of symbols may be respective repetitions (e.g., used to transmit the same data) as the first X symbols of the Y symbols in the second set of symbols.

In some aspects, the indication, transmitted by the first UE <NUM>-<NUM> to the second UE <NUM>-<NUM>, may include an indication of the repetition pattern for the first set of symbols. The repetition pattern may indicate which of the second set of symbols are repeated in the first set of symbols. For example, the repetition pattern may indicate X symbols of the Y symbols in the second set of symbols that are repeated in the first set of symbols. In some aspects, the repetition pattern may indicate that one or more symbols in the second set of symbols are repeated multiple times in the first set of symbols, which may allow the second UE <NUM>-<NUM> to use the repetitions of the same signal in the first set of symbols for performing AGC. In some aspects, the repetition pattern may indicate that the AGC symbol is repeated in the first set of symbols. In some aspects, the UE <NUM> may provide separate indications of the quantity of the first set of symbols and the repetition pattern for the first set of symbols. In some aspects, the indication of the repetition pattern for the first set of symbols may provide the indication of the quantity of the first set of symbols.

In some aspects, the base station <NUM> may configure the first UE <NUM>-<NUM> and the second UE <NUM>-<NUM> (e.g., via configuration messages transmitted from the base station <NUM>) with multiple quantity and/or repetition pattern options for the repetition symbols. In this case, the first UE <NUM>-<NUM> may select a quantity and/or repetition option from the multiple configured quantity and repetition pattern options, and the first UE <NUM>-<NUM> may transmit, to the second UE <NUM>-<NUM>, an indication of the selected quantity and repetition option. For example, the indication may include an index value associated with the selected quantity and/or repetition option.

In some aspects, the indication of the repetition pattern may include a bitmap that indicates which symbols in the second set of symbols are repeated in the first set of symbols. For example, the bitmap may be a bitmap of size Y that indicates X symbols to be repeated of the Y symbols in the second set of symbols. In this case, the bitmap may include a respective value for each of the Y symbols of the second set of symbols. A first value (e.g., <NUM>) for a symbol in the second set of symbols may indicate that the symbol is not repeated in the first set of symbols, and a second value (e.g., <NUM>) for a symbol in the second set of symbols may indicate that the symbol is repeated in the first set of symbols.

In some aspects, the indication, transmitted from the first UE <NUM>-<NUM> to the second UE <NUM>-<NUM>, may indicate a location of the first set of symbols (e.g., the repetition symbols) in the slot. For example, the first UE <NUM>-<NUM> may indicate, to the second UE <NUM>-<NUM>, whether the first set of symbols are transmitted at the beginning of the slot (e.g., the first X symbols in the slot after the AGC symbol), at the end of the slot (e.g., the last X symbols in the slot), or at another location in the slot (e.g., the last X PSSCH symbols in the slot).

In some aspects, the first UE <NUM>-<NUM> may transmit the indication of the quantity X of the first set of symbols (e.g., the repetition symbols) in the slot, the repetition pattern, and/or the location of the first set of symbols in the slot to the second UE <NUM>-<NUM> in at least one of a PC5 RRC message, a PC5 MAC-CE, or a dedicated PSSCH communication. In some aspects, the first UE <NUM>-<NUM> may transmit the indication of the quantity X, the repetition pattern, and/or the location of the first set of symbols in the slot to the second UE <NUM>-<NUM> in sidelink control information (SCI). For example, the first UE <NUM>-<NUM> may transmit the indication in first stage SCI (SCI-<NUM>) (e.g., included in a PSCCH communication) or in second stage SCI (SCI-<NUM>) (e.g., included in a PSSCH communication). In some aspects, the first UE <NUM>-<NUM> may transmit the indication using a new SCI format, in which SCI-<NUM> may be included in a repetition PSSCH symbol in the first set of symbols (e.g., a first repetition symbol in the first set of symbols). In this case, the SCI included in the repetition symbol (e.g., the first repetition symbol in the slot) may include the indication of the quantity X of repetition symbols and/or the repetition pattern for the repetition symbols.

In some aspects, the first UE <NUM>-<NUM> may transmit, in a slot, a sequential indication of the quantity X, the repetition pattern, and/or the location of the repetition signals for a next slot and/or one or more upcoming slots. For example, in some aspects, the first UE <NUM>-<NUM> may transmit SCI (e.g., SCI-<NUM> or SCI-<NUM>) in slot n that indicates the quantity X and/or the repetition pattern for slot n+<NUM>. In some aspects, the first UE <NUM>-<NUM> may transmit SCI (e.g., SCI-<NUM> or SCI-<NUM>) in slot n that indicates the quantity X and/or the repetition pattern for a set of slots (or transmissions) from slot n+<NUM> to slot n+Z. For example, the SCI in slot n may indicate a quantity X and/or repetition pattern that applies for all of the slots/transmissions in the set of slots/transmissions, or the SCI in slot n may indicate a respective quantity X and/or repetition pattern for each slot/transmission in the set of slots/transmissions. In some aspects, the first UE <NUM>-<NUM> may transmit an indication of Z (e.g., a number of upcoming slots or transmissions for which the current slot can provide the indication) to the second UE <NUM>-<NUM> in a PC5 RRC message, a PC5 MAC-CE, or SCI. In some aspects, the base station <NUM> may transmit an indication of Z to the first UE <NUM>-<NUM> and/or the second UE <NUM>-<NUM> in an RRC message, a MAC-CE, or DCI.

In some aspects, such as in the case of Mode <NUM> operation, the first UE <NUM>-<NUM> may select the quantity X of the first set of symbols (e.g., the repetition symbols) in a slot, the repetition pattern for the first set of symbols (e.g., from a plurality of configured quantity and repetition pattern options), and/or the location of the first set of symbols in the slot. In some aspects, the first UE <NUM>-<NUM> may select the quantity X, the repetition pattern, and/or the location of the first set of symbols in a slot based at least in part on information received from the second UE <NUM>-<NUM>, such as the requested quantity, repetition pattern, and/or location in the slot. In some aspects, the first UE <NUM>-<NUM> may select the quantity X, the repetition pattern, and/or the location of the first set of symbols in the slot without receiving the information from the second UE <NUM>-<NUM>, and/or independently from the information received from the second UE <NUM>-<NUM>. For example, the first UE <NUM>-<NUM> may determine the quantity Y of the second set of symbols to use to transmit a PSSCH transport block based at least in part on an amount of data to be transmitted in a PSSCH communication to second UE <NUM>-<NUM>, and the first UE <NUM>-<NUM> may select the quantity X of the first set of symbols (e.g., the quantity of repetition symbols) as the remaining quantity of PSSCH symbols in the slot.

In some aspects, such as in a case of Mode <NUM> operation, the base station <NUM> may select the quantity X, the repetition pattern, and/or the location of first set of symbols in the slot for a sidelink communication from the first UE <NUM>-<NUM> to the second UE <NUM>-<NUM>. In this case, the base station <NUM> may transmit an indication of the quantity X, the repetition pattern, and/or the location in the slot to the first UE <NUM>-<NUM> (e.g., in DCI), and the first UE <NUM>-<NUM> may transmit an indication of the quantity X, the repetition pattern, and/or the location in the slot to the second UE <NUM>-<NUM> (e.g., in SCI, a PC5 RRC message, a PC5 MAC-CE, and/or a dedicated PSSCH communication). In some aspects, the base station <NUM> may select the quantity X, the repetition pattern, and/or the location of the first set of symbols in the slot for the sidelink communication based at least in part on information received from the second UE <NUM>-<NUM> (e.g., directly or via the first UE <NUM>-<NUM>), such as the requested quantity, repetition pattern, and/or location in the slot. In some aspects, the base station <NUM> may select the quantity X, the repetition pattern, and/or the location of the first set of symbols in the slot for the sidelink communication without receiving the information from the second UE <NUM>-<NUM>, and/or independently from the information received from the second UE <NUM>-<NUM>.

As further shown in <FIG>, and by reference number <NUM>, the first UE <NUM>-<NUM> may transmit, to the second UE <NUM>-<NUM>, a sidelink communication including the first set of symbols and the second set of symbols in a slot. As shown in <FIG>, the first set of symbols in the slot may include X symbols (e.g., X = <NUM> in <FIG>), and the second set of symbols in the slot may include Y symbols (e.g., Y = <NUM> in <FIG>). The first UE <NUM>-<NUM> may transmit a PSSCH transmission including data to be decoded by the second UE <NUM>-<NUM> in the Y symbols of the second set of symbols, and the X symbols of the first set of symbols may repeat data transmitted in one or more symbols of the second set of symbols. For example, the X symbols of the first set of symbols may repeat the data transmitted in X symbols of the Y symbols of the second set of symbols. In some aspects, at least one symbol of the first set of symbols may repeat the AGC symbol.

The second UE <NUM>-<NUM> receives the downlink communication including the first set of symbols and the second set of symbols. In some aspects, the second UE <NUM>-<NUM> may perform rate-matching for PSSCH decoding across the second set of symbols. For example, the second UE <NUM>-<NUM>, based at least in part on the indication of the quantity of the first set of symbols received from the first UE <NUM>-<NUM>, may compute the transport block size for the sidelink communication (e.g., PSSCH communication) in the slot based on the Y symbols in the second set of symbols (e.g., and not based on the X symbols in the first set of symbols).

As further shown in <FIG>, and by reference number <NUM>, in some aspects, the second UE <NUM>-<NUM> may perform energy harvesting using the first set of symbols (e.g., the repetition symbols). In some aspects, based at least in part on receiving the indication of the quantity X of the first set of symbols (e.g., the repetition symbols), the second UE <NUM>-<NUM> may determine whether to perform energy harvesting using the first set of symbols. In some aspects, prior to performing energy harvesting, the second UE <NUM>-<NUM> may determine whether an energy level of the second UE <NUM>-<NUM> satisfies a threshold. Based at least in part on the threshold being satisfied, the second UE <NUM>-<NUM> may determine to perform energy harvesting using the first set of symbols. For example, the second UE <NUM>-<NUM> may have a low battery or may not have enough power to decode and/or transmit a response to the data included in the second set of symbols. In some aspects, the threshold may be preconfigured, for example, at a number between <NUM>% and <NUM>% of available power at the second UE <NUM>-<NUM>.

The second UE <NUM>-<NUM> may perform energy harvesting using all or a portion of the signals received in the first set of symbols. For example, the second UE <NUM>-<NUM> may harvest energy from all or a portion of the signals received in the first set of symbols, and the second UE <NUM>-<NUM> may use and/or store the harvested energy from the signals received in the first set of symbols. In some aspects, the second UE <NUM>-<NUM> may harvest energy from the signals received in all or a subset of the first set of symbols (e.g., using a time-switching architecture, as described elsewhere herein). In some aspects, the second UE <NUM>-<NUM> may harvest energy from all or a portion of the available power in the signals received in the first set of symbols (e.g., using a power-switching architecture, as described elsewhere herein).

As further shown in <FIG>, and by reference number <NUM>, the second UE <NUM>-<NUM> performs combined PSSCH decoding of one or more symbols in the second set of symbols using the first set of symbols (e.g., the repetition symbols). In particular, the second UE <NUM>-<NUM> uses combined decoding for some or all of the symbols in the second set of symbols that are repeated in the first set of symbols. For a symbol in the second set of symbols that includes a same data signal as a repetition symbol in the first set of symbols, the second UE <NUM>-<NUM> may decode the repetition symbol in the first set of symbols and the symbol in the second set of symbols, and the second UE <NUM>-<NUM> may combine LLRs resulting from decoding the two symbols to obtain the repeated data included in both symbols. As a result, the second UE <NUM>-<NUM> may improve the reliability of PSSCH decoding.

Further, the second UE <NUM>-<NUM> performs the combined decoding using all or a portion of the first set of symbols. For example, the second UE <NUM>-<NUM> may use a first portion of the first set of symbols to perform combined decoding, and use a second portion of the first set of symbols to perform energy harvesting and/or AGC. Additionally, the second UE <NUM>-<NUM> performs the combined decoding using all or a portion of the first set of symbols based at least in part on a determination not to perform energy harvesting using all or a portion of the first set of symbols. For example, the second UE <NUM>-<NUM> may determine to perform combined decoding using the first set of symbols based at least in part on a determination that the energy level of the second UE <NUM>-<NUM> does not satisfy the threshold for energy harvesting (e.g., a determination that energy harvesting is not currently needed by the second UE <NUM>-<NUM>).

As further shown in <FIG>, and by reference number <NUM>, the second UE <NUM>-<NUM> may perform AGC using all or a portion of the first set of symbols (e.g., the repetition symbols). For example, the second UE <NUM>-<NUM> may perform AGC using one or more symbols of the first set of symbols, in addition to the AGC performed using the AGC symbol in the slot. In this case, using additional signals for AGC may result in improved AGC for the second UE <NUM>-<NUM>, which may increase reliability of sidelink reception by the second UE <NUM>-<NUM>. In some aspects, the second UE <NUM>-<NUM> may use one or more of the symbols in the first set of symbols for AGC, and the second UE <NUM>-<NUM> may use the remaining symbols in the first set of symbols for energy harvesting and/or combined PSSCH decoding.

In some aspects, the second UE <NUM>-<NUM> may perform AGC using all or a portion of the first set of symbols based at least in part on a determination not to perform energy harvesting using all or a portion of the first set of symbols. For example, the second UE <NUM>-<NUM> may determine to perform AGC using one or more symbols of the first set of symbols based at least in part on a determination that the energy level of the second UE <NUM>-<NUM> does not satisfy the threshold for energy harvesting (e.g., a determination that energy harvesting is not currently needed by the second UE <NUM>-<NUM>).

In some aspects, the second UE <NUM>-<NUM> may use a first portion of the signals received in the first set of symbols for energy harvesting and a second portion of the signals received in the first set of symbols for combined decoding and/or AGC. In some aspects, the second UE <NUM>-<NUM> may harvest energy from the signals received in a first subset of the first set of symbols, and the second UE <NUM>-<NUM> may perform combined decoding and/or AGC using the signals received in a second subset of the first set of symbols (e.g., using a time-switching architecture, as described elsewhere herein). In some aspects, the second UE <NUM>-<NUM> may harvest energy from a first portion of the available power in the signals received in the first set of symbols, and the second UE <NUM>-<NUM> may use a second portion of the available power in the signals received in the first set of symbols for combined decoding with one or more of the second set of symbols and/or for AGC (e.g., using a power-switching architecture, as described elsewhere herein).
