[0001] This patent application claims priority over U.S. Patent Application No. 15 / 457,873 by Akkarakaran et al., entitled “Beam Reporting and Scheduling in Multicarrier Millimeter-Wave Communications”, filed March 13, 2017; and over U.S. Provisional Patent Application No. 62 / 350,630 by Akkarakaran et al., entitled “Beam Reporting and Scheduling in Multicarrier Millimeter-Wave Communications”, filed June 15, 2016; each of which is assigned to the present assignee. INTRODUCTION

[0002] The following refers generally to wireless communication with multi-carrier beamforming, and more specifically, to beam scheduling and reporting in communications with multi-carrier beamforming.

[0003] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may have the capability to support communication with multiple users through the sharing of available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include code-division multiple access (CDMA) systems, time-division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, and orthogonal frequency-division multiple access (OFDMA) systems (e.g., a long-term evolution (LTE) system). A wireless multiple access communication system Petition 870240051598, dated 06 / 18 / 2024, page 6 / 97 2 / 63 can include numerous base stations, each supporting simultaneous communication to multiple communication devices that may otherwise be known as a user equipment (UE).

[0004] Some wireless communication systems can operate in mmW frequency bands, for example, 28 GHz, 40 GHz, 60 GHz, etc. Wireless communication at these frequencies may be associated with increased signal attenuation (e.g., path loss), which can be influenced by various factors such as temperature, barometric pressure, diffraction, etc. As a result, signal processing techniques, such as beamforming, can be used to coherently combine energy and overcome path loss at these frequencies. Due to the increased amount of path loss in beamforming communication systems, transmissions from the UE may be beamformed. In frequency bands smaller than mmW frequency bands, UEs and base stations with a large number of antenna elements can use beamforming communications to increase reliability.

[0005] Some wireless communication systems can support multi-cell or carrier operation, a feature that may be referred to as carrier aggregation (CA) or multi-carrier operation. A carrier may also be called a component carrier (CC), a layer, a channel, etc. The terms carrier, component carrier, cell, and channel may be used interchangeably in this document. A UE 115 can be configured with multiple downlink CCs and one or more uplink CCs for carrier aggregation. Carrier aggregation can be used with carrier Petition 870240051598, dated 06 / 18 / 2024, page 7 / 97 3 / 63 component of both frequency division duplexing (FDD) and time division duplexing (TDD).

[0006] mmW communication promises to bring gigabit speeds to cellular networks due to the availability of large amounts of bandwidth. CA can be used to further increase available data rates and bandwidth. CA can include multi-cell or carrier operations. However, the unique challenges of heavy path loss faced by beamforming communication systems may result in the use of analog beamforming, which may have or utilize new functionality when combined with CA.

[0040] In a multi-carrier beamforming communication system, the multiple component carriers can share the same antenna panels; in such a case, the beams from the carriers will point in the same direction (e.g., a single beam carries all carriers). Alternatively, the carriers can be divided into groups, where carriers in the same group use the same panel, while those in different groups use different panels. In this case, beams from different groups can be pointed in different directions. In LTE, due to frequency selectivity across multiple carriers, UE reporting and measurement can be done separately on each component carrier. Frequency selectivity could also arise in communication systems with Petition 870240051598, dated 06 / 18 / 2024, page 18 / 97 14 / 63 beamforming. However, if the beams from all component carriers within a component carrier group are known to be in the same direction at the transmitter, then beam-related UE measurements can be combined across multiple component carriers.

[0041] For example, with separate measurements on each carrier, due to frequency selectivity, the strongest beam received at the UE may not be the same across all carriers. However, if the eNodeB is restricted to using the same beam across all carriers, these separate strongest beam reports can be combined across carriers in some way at the base station to determine which beam is used. For example, the base station might select a beam that is commonly reported for all carriers. However, if the UE reports different beam intensities across each carrier, then the base station can combine the across-carrier intensities for each beam and thus determine the overall strongest beam across all carriers. This solution, however, may require extensive reporting from the UE.To reduce uplink reporting overhead, it may be preferable to report at most a few stronger beams on each carrier.

[0042] In addition, in order for the UE to have the capability to use channel reciprocity by forming its uplink beams on each carrier, the UE may also have the capability to form a separate beam for each group of carriers that is sent in a common downlink beam. It is likely that the antenna panel locations on the UE may have different (and possibly heavier) constraints than those on the base station. In this way, the UE may have a set Petition 870240051598, dated 06 / 18 / 2024, page 19 / 97 15 / 63 differs from restrictions on the number of distinct beams to which carriers can be allocated.

[0043] The aspects of the disclosure are initially described in the context of a wireless communications system. For example, a base station may divide carriers into groups, for example, carrier group(s). Each carrier within the group may share antenna panel(s) to be directed by a transmission beam in the same direction, for example, with beamforming in the same direction. The base station may transmit a carrier grouping indication to a UE that identifies the division of carriers into the carrier group(s) and maps a group identifier for each carrier group to a beam identifier that identifies the corresponding transmission beam.The UE can receive the carrier grouping indication from the base station and receive the transmission(s) from the base station regarding UE communications in at least one of the carrier groups using one of the transmission beams that corresponds to the carrier group(s).

[0044] Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams and flowcharts relating to beam scheduling and reporting in multi-carrier beamforming communications.

[0045] Figure 1 illustrates an example of a wireless communications system 100, according to one or more aspects of the present disclosure. The wireless communications system 100 includes network access devices (e.g., base stations 105, gNodeBs (gNBs) and / or radio heads (RHs)), UEs 115 and a main network 130. In some examples, the wireless communications system 100 may be a Petition 870240051598, dated 06 / 18 / 2024, page 20 / 97 16 / 63 LTE network (or LTE-enhanced). In some examples, the 100 wireless communications system may be an advanced wireless communications system that operates in the millimeter wave spectrum, for example, an mmW wireless communications system.

[0046] Base stations 105 can communicate wirelessly with UEs 115 through one or more base station antennas. Each base station 105 can provide communication coverage for a respective geographic coverage area 110. The communication links 125 shown in wireless communication system 100 can include uplink (UL) transmissions from a UE 115 to a base station 105 or downlink (DL) transmissions from a base station 105 to a UE 115. UEs 115 can be dispersed throughout the wireless communication system 100, and each UE 115 can be stationary or mobile. A UE 115 may additionally or alternatively be referred to as a mobile station, a subscriber station, a remote unit, a wireless device, an access terminal (AT), a handset, a user agent, a client, or similar terminology.A UE 115 can additionally or alternatively be a mobile phone, a wireless modem, a handheld device, a personal computer, a tablet computer, a personal electronic device, a machine-type communication device (MTC), etc.

[0047] Base stations 105 can communicate with the main network 130 and with each other. For example, base stations 105 can interface with the main network 130 via backhaul links 132 (e.g., SI, etc.). Base stations 105 can communicate with each other on backhaul links 134 (e.g., X2, etc.) directly or indirectly (e.g., via the main network 130). A UE 115 can communicate with the main network 130 via communication link 135. As Petition 870240051598, dated 06 / 18 / 2024, page 21 / 97 17 / 63 base stations 105 can perform radio configuration and scheduling for communication with UEs 115, or they can operate under the control of a base station controller (not shown). In some examples, base stations 105 may be macrocells, small cells, access points, or similar. Base stations 105 may additionally or alternatively be referred to as eNodeBs (eNBs) 105. In some examples, base station 105 may additionally or alternatively be referred to as gNBs.

[0048] The wireless communications system 100 can operate in an ultra-high frequency (UHF) region using frequency bands from 700 MHz to 2,600 MHz (2.6 GHz), although, in some cases, wireless local area networks (WLANs) can use frequencies as high as 4 GHz. This region may also be known as the decimeter band, since the wavelengths lie in the range of approximately one decimeter to one meter in length. UHF waves can propagate primarily by line of sight and can be blocked by buildings and environmental features. However, the waves can penetrate walls sufficiently to provide service to UEs 115 located indoors.UHF wave transmission is characterized by smaller antennas and shorter range (e.g., less than 100 km) compared to transmission using the lower frequencies (and longer wavelengths) of the high-frequency (HF) or very high-frequency (VHF) portion of the spectrum. In some cases, the wireless communication system may use extremely high-frequency (EHF) portions of the spectrum (e.g., from 30 GHz to 300 GHz). This region may be known as the millimeter band, since the wavelengths lie in the range from approximately one millimeter to one centimeter in length. Therefore, the... Petition 870240051598, dated 06 / 18 / 2024, p. 22 / 97 18 / 63 EHF antennas can be even smaller and more closely spaced than UHF antennas. In some cases, this can facilitate the use of antenna arrays within a UE 115 (e.g., for directional beamforming). However, EHF transmissions may be subject to even greater atmospheric attenuation and shorter range than UHF transmissions.

[0049] In some cases, base station antennas may be located within one or more antenna arrays. One or more base station antennas or antenna arrays may be placed on an antenna mount, such as an antenna tower. In some cases, the antennas or antenna arrays associated with a base station 105 may be located in various geographical locations. A base station 105 may multiply the use of antennas or antenna arrays to conduct beamforming operations for directional communications with a UE 115.

[0050] In some cases, a base station 105 and a UE 115 can communicate using more than one carrier. Each aggregated carrier is called a CC. Each component can have a bandwidth of, for example, 1.4, 3, 5, 10, 15, or 20 MHz. In some cases, the number of The number of carriers (CCs) can be limited to, for example, a maximum of five, given the maximum aggregate bandwidth of 100 MHz. In FDD, the number of aggregate carriers may differ from DL and UL. The number of UL component carriers may be equal to or less than the number of DL component carriers. Individual component carriers may additionally or alternatively have different bandwidths. For TDD, the number of CCs, as well as the bandwidths of each CC, will normally be the same for DL ​​and UL. Component carriers can be arranged in various ways. For example, a CA configuration may be based on... Petition 870240051598, dated 06 / 18 / 2024, page 23 / 97 19 / 63 contiguous component carriers within the same operating frequency band, that is, called intraband contiguous AC. Non-contiguous allocations can also be used, where the component carriers can be intra-band or inter-band.

[0051] In some cases, the 100 wireless communications system may use enhanced component carriers (eCCs). An eCC may be characterized by one or more features including: wider bandwidth, shorter symbol duration, shorter TTIs, and modified control channel configuration. In some cases, an eCC may be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple server cells have a non-ideal or suboptimal backhaul link). An eCC may additionally or alternatively be configured for use in unlicensed spectrum or shared spectrum (where more than one operator is permitted to use the spectrum). An eCC characterized by wide bandwidth may include one or more segments that may be used by UEs 115 that do not have the capacity to monitor the entire bandwidth or prefer to use a limited bandwidth (e.g., to conserve power).

[0052] In some cases, an eCC may use a different symbol duration than other CCs, which may include the use of a reduced symbol duration compared to the symbol durations of other CCs. A shorter symbol duration is associated with increased subcarrier spacing. A device, such as a UE 115 or base station 105, that uses eCCs can transmit broadband signals (e.g., 20, 40, 60, 80 MHz, etc.) at reduced symbol durations (e.g., 16.67 microseconds). A TTI in eCC may comprise one or multiple symbols. In some cases, Petition 870240051598, dated 06 / 18 / 2024, p. 24 / 97 20 / 63 The duration of a TTI (that is, the number of symbols in a TTI) can be variable.

[0053] The 100 wireless communications system may be or include a multi-carrier beamforming wireless communications system. Broadly, aspects of the 100 wireless communications system may include a UE 115 and a base station 105 that inform each other about which CCs are restricted from sharing the same transmission beam. For example, a base station 105 may include a base station beamforming communication module 101 that can divide carriers into groups, for example, carrier group(s). Each carrier within the group may share antenna panel(s) to be directed by a transmission beam in the same direction, for example, with beamforming in the same direction.The base station 101 beamforming communication module can transmit a carrier grouping indication to a UE 115 that identifies the division of carriers into the carrier group(s) and maps a group identifier for each carrier group to a beam identifier that identifies the corresponding transmission beam. The UE 115 may include a UE 102 beamforming communication module that can receive the carrier grouping indication from base station 105 and receive the transmission(s) from base station 105 regarding UE communications in at least one of the carrier groups using one of the transmission beams that corresponds to the carrier group(s).

[0054] Figure 2 illustrates an example of a 200 wireless communications system for beam scheduling and reporting in multi-carrier beamforming communications, according to one or more aspects of the present Petition 870240051598, dated 06 / 18 / 2024, page 25 / 97 21 / 63 disclosure. Wireless communications system 200 can be an example of aspects of wireless communications system 100 in Figure 1. Wireless communications system 200 can include a UE 115-a, a base station 105-ae, or a base station 105-b, which can be examples of the corresponding devices in Figure 1.

[0055] Base station 105-a may be a service base station for UE 115-a (additionally or alternatively referred to as a primary cell or PCell). Base station 105-b may be a neighboring base station for UE 115-a (additionally or alternatively referred to as a secondary cell or SCell). Base station 105-ae / or base station 105-b may be mmW base stations that transmit beamforming signals using one or more antenna panels. Transmissions from base station 105-ae / or base station 105-b may be beamforming transmissions that are directional towards UE 115-a. Base station 105-ae / or base station 105-b may additionally or alternatively support multicarrier communications using one or more component carriers in a beamforming wireless communication system.

[0056] For example, base station 105-a can transmit a beamforming transmission 205 to UE 115-a. The beamforming transmission 205 can include a plurality of carriers 210 that are divided into one or more carrier groups 215. Similarly, base station 105-b can transmit a beamforming transmission 220 to UE 115-a that includes a carrier group 225 that has a plurality of carriers. It should be understood that the wireless communications system 200 can have more than one carrier group 215 and / or carrier group 225. It should also be understood that each group of Petition 870240051598, dated 06 / 18 / 2024, p. 26 / 97 22 / 63 carrier may include more or less than three 210 carriers.

[0057] In some respects, base station 105-a can indicate to UE 115-a the division of carriers into groups, where all carriers within a group can use the same transmission beam, for example, they can be transmitted in the same direction. For example, this could be indicated in a Radio Resource Configuration (RRC) message that configures UE 115-a to receive additional carriers, after UE 115-a receives the RRC-connected message on the primary carrier.

[0058] In some respects, UE 115-a can report to the network (e.g., to or through base station 105-a) the constraints of UE 115-a (e.g., an indication of carrier grouping capability) on how carriers can be grouped into distinct uplink beams. Based on these UE 115-a reports, the network can choose to reconfigure the carrier groups. For example, if base station 105-a has the capacity to support two carrier groups, but UE 115-a can only support one carrier group (e.g., all uplink carriers have to be on the same beam), then base station 105-a can be configured so that both of its carrier groups use the same beam, thus combining them into a single carrier group, to better allow the use of channel reciprocity across all carriers.

[0059] In some respects, UE 115-a can send two types of beam measurement reports, for example, a “carrier measurement report” and a “carrier group measurement report”. Carrier measurements for the carrier group measurement report can be performed by processing the reference signals. Petition 870240051598, dated 06 / 18 / 2024, page 27 / 97 23 / 63 beam of all carriers within the group as if they originated from a single carrier. For example, the frequency window over which coherent matching is performed can be expanded to encompass multiple carriers in that group. In some respects, the carrier measurement report in this context can refer to both periodic and aperiodic reports, and both short-term and long-term reports.

[0060] Base station 105-a can signal in the carrier measurement request whether a carrier-based or carrier-group-based measurement report is requested. Alternatively, if the measurement is triggered by a UE 115-a event, UE 115-a can determine the type of carrier measurement report based on various criteria such as uplink quality (e.g., use more compact carrier-group-based report if uplink is heavily loaded).

[0061] In an example where measurements for multiple downlink carriers are reported on a single uplink carrier, the carrier measurement report may require a field denoting the carrier identity. To report a measurement on a downlink carrier group, any one of the corresponding uplink carriers may suffice. If reporting multiple downlink carrier group measurements on a single uplink carrier, a field for carrier group identity may be used in the uplink report.

[0062] Neighboring cell measurements, for example, base station 105-b, can initially be reported separately by carrier. Subsequently, base station 105-b and UE 115-a can negotiate carrier groups at base station 105-b using the techniques described. Petition 870240051598, dated 06 / 18 / 2024, page 28 / 97 24 / 63 above, and then also generate measurement reports by carrier group at base station 105-b.

[0063] In some configurations, the techniques described may not use carrier group reports and instead rely on scheduling and carrier reports. Carrier group reports allow finding the best common beam to use for all carriers within the group. In some configurations, UE 115-a reports the best beam for each carrier in the group separately; this may be different for different carriers. The transmission antenna panel restriction may prevent base station 105-ae / or base station 105-b from using different beams on different carriers in the same TTI, therefore, base station 105-ae / or base station 105-b may schedule UE 115-a on different carriers in different TTIs.This can include a higher scheduling overhead, for example, due to a lack of timing coordination of scheduling across carriers, each carrier may use its own downlink control information (DCI) scheduling grant. With the use of carrier groups, on the other hand, a new scheduling grant can be designed to schedule UE 115-a simultaneously (on the same TTI) on all carriers in the carrier group. This can reduce the scheduling overhead. Additional constraints can be introduced to further or alternatively reduce the decoding overhead of scheduling grants on UE 115-a.For example, a grant that schedules an UE in a whole carrier group can be transmitted on a carrier within that group; and if present, the other carriers in the group refrain from carrying scheduling grants for that UE, thus making it unnecessary for the UE to search for scheduling grants. Petition 870240051598, dated 06 / 18 / 2024, page 29 / 97 25 / 63 on those other carriers. This applies to both uplink and downlink scheduling grants. In some respects, uplink scheduling grants that apply across a carrier group may use a different definition of carrier groups compared to downlink, to reflect the different antenna panel constraints in uplink compared to downlink.

[0064] Thus, the techniques described can support beam scheduling and reporting in a multi-carrier beamforming wireless communication system, such as the 200 system. For example, base station 105-a can divide a plurality of carriers into groups. Each carrier within a group can share an antenna panel(s) so that it is directed by a transmission beam in the same direction. Base station 105-a can transmit to UE 115-a a carrier grouping indication that identifies the division of the plurality of carriers into the group(s) and maps a group identifier for at least one of the groups to a beam identifier that identifies the corresponding transmission beam. Base station 105-a can receive from UE 115-a a carrier grouping capability indication that indicates UE restriction(s) on the division of the plurality of carriers.Base station 105-a can determine the probability of modifying carrier plurality splitting based at least in part on carrier clustering capability indication.

[0065] Base station 105-a can transmit to UE 115-a a request for carrier measurement report(s). The request can indicate whether UE 115-a should provide one or more reports on a per-base basis. Petition 870240051598, dated 06 / 18 / 2024, page 30 / 97 26 / 63 carrier (e.g., one report per carrier), one or more reports on a per-group basis (e.g., one report per carrier group), or combinations thereof. Base station 105-a may indicate to UE 115-a that the carrier measurement report(s) for carriers of at least one group should be transmitted on a single respective carrier. Base station 105-a may receive from UE 115-a a carrier measurement report(s) representing carrier measurements from each group. The carrier measurement report(s) may include one or more reports on a per-carrier basis for carriers within each group. The carrier measurement report(s) may include one or more reports on a per-group basis for all carriers within each group.The carrier measurement report(s) may include periodic or aperiodic reports, and short-term or long-term average reports. Base station 105-a may receive the carrier measurement report(s) for carriers of at least one group on a single respective carrier. The carrier measurement report(s) for the carriers of at least one group may each include a carrier identity field.

[0066] Base station 105-a may transmit, on one carrier among a plurality of carriers, a single scheduling grant to UE 115-a to simultaneously schedule UE 115-a on one or more carriers within one or more groups. Base station 105-a may refrain from transmitting additional scheduling grants to the carrier(s) within one or more groups during the same TTI as that in which the single scheduling grant is transmitted. In some respects, Petition 870240051598, dated 06 / 18 / 2024, p. 31 / 97 27 / 63 The division of the plurality of carriers into one or more groups is specific to the EU.

[0067] Base station 105-b can negotiate with UE 115-a to use carrier grouping. Base station 105-b can receive carrier-based measurement reports from UE 115-a before negotiating with UE 115-a, and receive group-based measurement reports from UE 115-a after negotiating with UE 115-a.

[0068] Figure 3 illustrates an example of a 300 process flow for beam scheduling and reporting in multi-carrier beamforming communications, according to one or more aspects of the present disclosure. Process flow 300 can implement aspects of wireless communication system 100 from Figure 1 and / or wireless communication system 200 from Figure 2. Process flow 300 can include a UE 115-b and a base station 105-c, which can be examples of the corresponding devices in Figure 1 and / or Figure 2.

[0069] In 305, base station 105-c can divide a plurality of carriers into one or more groups. Each carrier within a group can share antenna panel(s) so that each is directed by a transmission beam in the same direction. In some instances, the division of the plurality of carriers may be UE-specific, for example, particular to UE 115-b.

[0070] In 310, base station 105-c can transmit to UE 115-b a carrier group indication that identifies the division of carrier plurality in the group (or groups). The carrier group indication can map a group identifier for at least one group to a beam identifier that identifies the corresponding transmission beam.

[0071] In some respects, base station 105-c may receive additional restriction information from Petition 870240051598, dated 06 / 18 / 2024, p. 32 / 97 28 / 63 UE 115-b, so that base station 105-c can modify the grouping and send an updated message to UE 115-b. In this way, the grouping can be based on either base station 105-c or UE 115-b.

[0072] In 315, base station 105-c can transmit (and UE 115-b can receive) transmissions regarding UE 115-b communications in at least one of the groups using one of the transmission beams that corresponds to at least one group.

[0073] In some respects, the 105-c base station may require measurement reports from the UE 115-b on a carrier-by-carrier basis and / or on a carrier-group (or group) basis. The 105-c base station may indicate to the UE 115-b that it carries how many carriers, etc., measurement reports should be provided. Measurement reports by carrier group may include a measurement associated with all carriers in the group and / or may include a measurement associated with one or more individual carriers in the group. Measurement reports may be periodic and / or aperiodic and may additionally or alternatively be short-term and / or long-term reports.

[0074] In some respects, base station 105-c can negotiate with a second UE (not shown) using the techniques described. For example, base station 105-c can negotiate with the second UE to establish carrier grouping for communications with the second UE. The base station The 105-c can receive carrier-based measurement reports from the second UE before negotiation and receiver carrier-group measurement reports from the second UE after negotiation. Similarly, the UE 115-b can negotiate with a neighboring base station (not shown) using the techniques described. For example, the UE 115-b can negotiate with the neighboring base station to establish the Petition 870240051598, dated 06 / 18 / 2024, page 33 / 97 29 / 63 Carrier grouping for communications between the UE 115-b and neighboring base station. The UE 115-b can transmit carrier-based measurement reports to the neighboring base station before negotiation and transmit carrier-based measurement reports to the neighboring base station after negotiations.

The 400 process flow may include a UE 115-ce and a 105-d base station, which may be examples of the corresponding devices in Figures 1 to 3.

[0076] In 405, the 105-d base station can divide a plurality of carriers into one or more groups. Each carrier within a group can share antenna panel(s) so that each is directed by a transmission beam in the same direction. In some instances, the division of the plurality of carriers may be UE-specific, for example, particular to UE 115-c.

[0077] On 410, base station 105-d can transmit to UE 115-c a carrier group indication that identifies the division of carrier plurality into the group (or groups). The carrier group indication can map a group identifier for at least one group to a beam identifier that identifies the corresponding transmission beam.

[0079] In 430, base station 105-d may transmit transmission(s) in relation to UE 115-c communications in at least one of the groups using one of the transmission beams that corresponds to at least one group. UE 115-c may receive, on a carrier among the plurality of carriers in the carrier group, a single scheduling grant to simultaneously schedule UE 115-c on one or more carriers within one of the one or more carrier groups.

[0080] In 435, base station 105-d can transmit to UE 115-c a request for one or more carrier measurement reports.

[0155] The techniques described in this document can be used for various wireless communication systems such as CDMA, TDMA, FDMA, OFDMA, single carrier frequency division multiple access (SC-FDMA), and other systems. The terms “system” and “network” are often used interchangeably. A CDMA system may implement a radio technology such as CDMA2000, Universal Terrestrial Radio Access (UTRA), etc. CDMA2000 encompasses the IS standards. [Illegible text - likely OCR error] 56 / 63 2000, IS-95, and IS-856. IS-2000 versions are commonly referred to as CDMA2000 IX, IX, etc. IS-856 (TIA-856) is commonly referred to as CDMA2000 1xEV-DO, High Rate Packet Data (HRPD), etc. UTRA includes Wideband CDMA (WCDMA) and other CDMA variants. The TDMA system can implement radio technologies such as the Global System for Mobile Communications (GSM).

[0156] An OFDMA system can deploy a radio technology such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunication System (UMTS). LTE and LTE-A (LTE-A) of 3GPP are new versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and the Global System for Mobile Communications (GSM) are described in documents from an organization called the “Third Generation Partnership Project” (3GPP). CDMA2000 and UMB are described in documents from an organization called the Third Generation Partnership Project 2 (3GPP2). The techniques described in this document can be used for the radio systems and technologies mentioned above, as well as other radio systems and technologies.Although aspects of an LTE system may be described for illustrative purposes, and LTE terminology may be used throughout the description, the techniques described in this document are applicable beyond LTE applications.

[0157] In LTE / LTE-A networks, including such networks described in this document, the term eNB may, for example, be used to describe base stations. The wireless communication systems described in this document may include a heterogeneous LTE / LTE-A network in which different types of eNBs provide coverage for various Petition 870240051598, dated 06 / 18 / 2024, pp. 61 / 97 57 / 63 geographic regions. For example, each eNB or base station can provide communication coverage for a macrocell, a small cell, or other cell types. The term cell can be used to describe a base station, a carrier or component carrier associated with a base station, or a coverage area (e.g., sector, etc.) of a carrier or base station, depending on the context.

[0158] Base stations may include, or may be referred to by those skilled in the art as, a transceiver base station, a radio base station, an access point, a radio transceiver, a NodeB, eNB, home NodeB, home eNodeB, or some other suitable terminology. The geographic coverage area for a base station may be divided into sectors that constitute a portion of the coverage area. The wireless communication systems or system described herein may include base stations of different types (e.g., macro-cell or small-cell base stations). The UEs described herein may have the capability to communicate with various types of base stations and network equipment including macro-eNBs, small-cell eNBs, relay base stations, and the like. There may be overlapping geographic coverage areas for different technologies.

[0159] A macrocell covers a relatively large geographical area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell is a lower-power base station, compared to a macrocell, that may operate in the same or different frequency bands (e.g., licensed, unlicensed, etc.) as macrocells. Small cells may include picocells, femtocells, and Petition 870240051598, dated 06 / 18 / 2024, pp. 62 / 97 58 / 63 microcells according to various examples. A picocell, for example, can cover a small geographic area and can allow unrestricted access by UEs with service subscriptions with the network provider. A femtocell can also cover a small geographic area (e.g., a residence) and can provide restricted access by UEs that have an association with the femtocell (e.g., UEs in a closed subscriber group (CSG), UEs for users in the residence, and similar). An eNB for a macrocell can be referred to as a macro eNB. An eNB for a small cell can be referred to as a small cell eNB, a pico eNB, a femto eNB, or a home eNB. An eNB can support one or multiple (e.g., two, three, four, and similar) cells (e.g., component-bearer). A gNB for a macrocell can be referred to as a macro gNB.A gNB for a small cell may be referred to as a small-cell gNB, a pico gNB, a femto gNB, or a domestic gNB. A gNB may support one or multiple (e.g., two, three, four, and similar) cells (e.g., component-carriers). A UE may have the capability to communicate with various base stations and network equipment including macro eNBs, small-cell eNBs, macro gNBs, small-cell gNBs, relay base stations, and the like.

[0160] The wireless communication systems described in this document may support synchronous or asynchronous operation. For synchronous operation, base stations may have similar frame timing and transmissions from different base stations may be approximately time-aligned. For asynchronous operation, base stations may have different frame timing and transmissions from different base stations may not be time-aligned. Petition 870240051598, dated 06 / 18 / 2024, p. 63 / 97 59 / 63 techniques described in this document can be used for synchronous or asynchronous operations.

[0161] The downlink transmissions described in this document may also be called forward link transmissions, while the uplink transmissions may also be called backward link transmissions. Each communication link described in this document, which includes, for example, wireless communication systems 100 and 200 of Figures 1 and 2, may include one or more carriers, where each carrier may be a signal consisting of multiple subcarriers (e.g., waveform signals of different frequencies).

[0162] The description presented above in this document, together with the accompanying drawings, describes exemplary configurations and does not represent all examples that can be implemented or that are within the scope of the claims. The term “exemplary,” as used in this document, means “serving as an example, occurrence, or illustration,” and not “preferential” or “advantageous in relation to other examples.” The detailed description includes specific details for the purpose of providing an understanding of the techniques described.
