Description

Technical Field

[0001] Aspects of the technologies described below generally relate to wireless communication, and more particularly, to techniques and apparatus for indicating the energy level of a resynchronization signal (RSS). Some of the techniques and apparatus described herein implement and provide wireless communication devices and systems configured for enhanced network coverage and improved radio resource management.

[0002] Introduction

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple access technology capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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). LTE / Advanced LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0004] A wireless communication network may include several base stations (BSs) capable of supporting communication of several user equipments (UEs). A user equipment (UE) may communicate with a base station (BS) via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. A BS may be referred to as a B node, gNB, access point (AP), radio head, transmission reception point (TRP), New Radio (NR) BS, 5G B node, and so on.

[0005] Multiple access technologies have been adopted in various telecommunication standards. The wireless communication standards provide a common protocol that enables different devices (e.g., user equipments) to communicate at the urban, national, regional, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhanced set of the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). As the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. These improvements may be applicable to other multiple access technologies and telecommunication standards that employ these technologies.

[0006] Brief Overview of Some Examples

[0007] The following presents some aspects of the present disclosure to provide a basic understanding of the technologies discussed. This overview is not an exhaustive survey of all contemplated features of the present disclosure, and is neither intended to identify key or critical elements of all aspects of the present disclosure nor to attempt to define the scope of any or all aspects of the present disclosure. The purpose of this overview is to present some concepts of one or more aspects of the present disclosure in an overview form as a prelude to the more detailed description that follows.

[0008] Some UEs may use low-power or bandwidth-constrained configurations, such as bandwidth-limited (BL) UEs, coverage-enhanced (CE) UEs, etc. Such UEs may enter a sleep mode for long periods of time to conserve battery power between active periods. During the sleep period of the UE, synchronization with the serving cell may drift. Compared to synchronization using primary synchronization signals (PSSs), secondary synchronization signals (SSSs), physical broadcast channels (PBCHs), etc., resynchronization signals (RSSs) may facilitate faster resynchronization to the serving cell after the sleep period. For example, PSSs, SSSs, and / or PBCHs may not be transmitted frequently and may use relatively little resource allocation, which complicates and delays synchronization. RSSs may use long, consistent resource allocations (e.g., tens of milliseconds), which can simplify the detection of UEs waking up from long sleep periods during which synchronization has drifted.

[0009] UEs may use downlink reference signals, such as RSSs or cell-specific reference signals (CRSs), to perform measurements, such as radio resource management (RRM) measurements on neighbor cells, etc. To perform measurements using RSSs, UEs may benefit from knowledge of the RSS configurations of neighbor cells, such as the energy levels of the RSSs to be transmitted by these neighbor cells. However, there may be an overhead associated with signaling the RSS configurations of neighbor cells, which may be proportional to the complexity of such signaling. This overhead may reduce throughput and increase the latency associated with configuring RRM measurements for the UE.

[0010] The various techniques and apparatuses described herein provide signaling of energy levels. In some aspects, the signaled energy levels may be associated with the RSS of neighbor cells (e.g., in a list of neighbor cells provided by a serving cell). In other aspects, the energy levels associated with the RSS may be indicated relative to the energy level of the CRS of the neighbor cell. Doing so may save resources that would otherwise be used to indicate the energy level of the RSS relative to a baseline or absolute value. In some aspects, the energy level of the RSS may be signaled as an offset (e.g., a quantized offset) relative to the energy level of the CRS. This may reduce overhead compared to explicit signaling of the energy level of the RSS relative to the energy level of the CRS. In some aspects, the energy level of the RSS may be signaled explicitly (e.g., using one or more parameters that may be used to determine the energy level of the RSS relative to the energy level of the CRS). Explicit signaling may provide improved accuracy compared to signaling an offset or quantization of an offset. Additionally, some of the techniques and apparatuses described herein may provide a combination of RSS-based and CRS-based measurements (e.g., in cases where the relative power of the RSS and CRS is within a particular range). Such a combined measurement of this nature may improve the accuracy and robustness of RRM measurements. Thereby, RRM measurements using the RSS are enabled and the overhead associated with signaling the energy level of the RSS is reduced.

[0011] In some aspects, a wireless communication method performed by a user equipment (UE) may include: receiving information indicating an offset of an energy level of an RSS of a neighbor cell relative to a CRS of the neighbor cell; and performing a measurement at least in part based on the offset.

[0012] In some aspects, a wireless communication method performed by a base station may include: receiving from a neighbor base station associated with a neighbor cell information indicating an offset of an energy level of an RSS of the neighbor cell relative to a CRS of the neighbor cell; and transmitting a list of neighbor cells including the information indicating the offset.

[0013] In some aspects, a wireless communication method performed by a base station may include: determining an offset of an energy level of an RSS of the base station relative to a CRS of the base station; and transmitting the RSS and the CRS according to the offset.

[0014] In some aspects, a base station for wireless communication may include a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to: receive information indicating an offset of an energy level of an RSS of a neighbor cell relative to a CRS of the neighbor cell; and perform a measurement at least in part based on the offset.

[0015] In some aspects, a base station for wireless communication may include a memory and one or more processors operatively coupled to the memory.

[0016] In some aspects, a base station for wireless communication may include a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to: determine an offset of an energy level of an RSS of the base station relative to a CRS of the base station; and transmit the RSS and the CRS based on the offset.

[0017] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a UE, may cause the one or more processors to: receive information indicating an offset of an energy level of an RSS of a neighbor cell relative to a CRS of the neighbor cell; and perform measurements at least in part based on the offset.

[0018] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a base station, may cause the one or more processors to: receive information indicating an offset of an energy level of an RSS of a neighbor cell relative to a CRS of the neighbor cell from a neighbor base station associated with the neighbor cell; and transmit a neighbor cell list including the information indicating the offset.

[0019] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a base station, may cause the one or more processors to: determine an offset of an energy level of an RSS of the base station relative to a CRS of the base station; and transmit the RSS and the CRS based on the offset.

[0034] Detailed Description

[0035] Various aspects of the present disclosure will now be described more fully with reference to the accompanying drawings. However, the present disclosure may be implemented in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice a method. Additionally, the scope of the present disclosure is intended to cover such apparatus or methods practiced using other structures, functionality, or a combination of structures and functionality that supplement or are additional to the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be implemented by one or more elements of a claim.

[0036] Certain aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements" or "features"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0037] Although some aspects may be described herein using terms typically associated with 3G and / or 4G wireless technologies, aspects of the present disclosure may be applied to communication systems based on other generations (such as 5G and later generations, including NR technologies).

[0038] While aspects and embodiments are described herein by way of illustration of some examples, those skilled in the art will understand that additional implementations and use cases can arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, packaging arrangements. For example, the embodiments and / or uses can be generated via integrated chip embodiments and / or other non-module component-based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchase devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specific to particular use cases or applications, a broad applicability of the described innovations can occur. The scope of implementations can range from chip-level or module components to non-module, non-chip-level implementations and further to aggregated, distributed, or original equipment manufacturer devices or systems incorporating one or more aspects of the described innovations. In some practical environments, devices incorporating the described aspects and features may also necessarily include additional components and features for implementing and practicing the claimed and described embodiments. For example, the transmission and reception of wireless signals necessarily includes several components for analog and digital purposes (e.g., hardware components including one or more antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). The innovations described herein are intended to be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, end-user devices, etc. of various sizes, shapes, and configurations.

[0039] Figure 1 FIG. is a diagram illustrating a wireless network 100 in which aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmission reception point (TRP), etc. Each BS may provide communication coverage for a particular area (e.g., a fixed or varying geographical area). In some scenarios, the BS 110 may be stationary or non-stationary. In some non-stationary scenarios, the mobile BS 110 may move at varying speeds, directions, and / or altitudes. In 3GPP, the term "cell" may refer to the coverage area of the BS 110 and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0040] The BS can provide communication coverage for macro cells, picocells, femtocells, and / or another type of cell. A macro cell can cover a relatively large geographical area (e.g., with a radius of several kilometers) and can allow unconstrained access by UEs with service subscriptions. Additionally or alternatively, the BS can support access to unlicensed RF bands (e.g., Wi-Fi bands, etc.). A picocell can cover a relatively small geographical area and can allow unconstrained access by UEs with service subscriptions. A femtocell can cover a relatively small geographical area (e.g., a residence) and can allow constrained access by UEs associated with the femtocell (e.g., UEs in a closed subscriber group (CSG)). The BS for a macro cell can be referred to as a macro BS. The BS for a picocell can be referred to as a pico BS. The BS for a femtocell can be referred to as a femto BS or a home BS. In the example shown in Figure 1 BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for picocell 102b, and BS 110c can be a femto BS for femtocell 102c. The BS can support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" can be used interchangeably herein.

[0041] In some aspects, the cell may not have to be stationary, and the geographical area of the cell can move according to the location of the mobile BS. In some aspects, the BSs can be interconnected with each other and / or interconnected to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces such as direct physical connections, virtual networks, and / or analogs using any suitable transport network. In other scenarios, the BS can be implemented in a software-defined network (SDN) manner or via a network function virtualization (NFV) manner.

[0042] The wireless network 100 can also include relay stations. A relay station is an entity that can receive the transmission of data from an upstream station (e.g., a BS or a UE) and send the transmission of the data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. In the example shown in Figure 1 relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. The relay station can also be referred to as a relay BS, a relay base station, a relay, etc.

[0043] The wireless network 100 can be a heterogeneous network including different types of BSs (e.g., macro BS, pico BS, femto BS, relay BS, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0044] The network controller 130 can be coupled to a set of BSs and can provide coordination and control for these BSs. The network controller 130 can communicate with each BS via a backhaul. These BSs can also communicate with each other directly or indirectly, e.g., via a wireless or wired backhaul.

[0045] UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UEs can also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE can 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, a superbook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a robot, a drone, an implantable device, an augmented reality device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0046] Some UEs may be considered machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to a network (e.g., a wide area network such as the Internet or a cellular network) or provide connectivity to the network, for example, via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as narrowband IoT (NB-IoT) devices. Some UEs may be considered customer premise equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as processor components, memory components, etc. These components may be integrated in various combinations and / or may be self-standing distributed components, given design constraints and / or operational preferences.

[0047] Generally, any number of wireless networks may be deployed in a given geographical area. Each wireless network may support a specific RAT and may operate on one or more frequencies. The RAT may also be referred to as a radio technology, an air interface, etc. The frequency may also be referred to as a carrier, a frequency channel, etc. Each frequency may support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network may be deployed.

[0048] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., communicate with each other without using the base station 110 as an intermediary). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110. A UE that performs scheduling operations may include or perform base station-like functions in these deployment scenarios.

[0049] As indicated above, Figure 1 is provided merely as an example. Other examples may be different from the example regarding Figure 1 described.

[0050] Figure 2 A block diagram of a design 200 of a base station 110 and a UE 120 is shown, where the base station 110 and the UE 120 may be Figure 1One of the base stations and one of the UEs in []. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, where generally T≥1 and R≥1. These T and R antennas may be configured with multiple antenna elements for array formation for MIMO or massive MIMO deployments that may occur in a millimeter wave (mmWave or mmW) communication system.

[0051] At the base station 110, the transmit processor 220 may perform several functions associated with communication. For example, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCSs) for the UE at least partially based on the channel quality indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for the UE at least partially based on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols when applicable, and provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process its respective output symbol stream (e.g., for orthogonal frequency division multiplexing, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from the modulators 232a to 232t may be transmitted via the T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be utilized to generate synchronization signals to convey additional information.

[0052] At the UE 120, antennas 252a through 252r may receive downlink radio frequency (RF) signals. The downlink RF signals may be received from and / or transmitted by one or more base stations 110. These signals may be provided to demodulators (DEMOD) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, and digitize) the received signals to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 may obtain the received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols when applicable, and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The channel processor may determine the reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 120 may be included in a housing.

[0053] For uplink communication, the UE 120 may transmit control information and / or data to another device, such as one or more base stations 110. For example, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266 when applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, the uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 when applicable, and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0054] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 any other component(s) thereof may perform one or more techniques associated with an indication of the energy level of a resynchronization signal, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 any other component(s) thereof may perform or direct, for example, Figure 4 process 400 of Figure 5 process 500 of Figure 6 process 600 of, and / or the operation of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. Scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0055] In some aspects, UE 120 may include various means or components for implementing communication functions. For example, the various means may include: means for receiving information indicating an offset of the energy level of a resynchronization signal (RSS) of a neighboring cell relative to a cell-specific reference signal (CRS) of the neighboring cell; means for performing measurements at least in part based on the offset; means for determining the energy level at least in part based on the offset; means for combining RSS-based measurements and CRS-based measurements to determine the measurement; and so on.

[0056] In some aspects, UE 120 may include various structural components for performing the functions of the various means. In some aspects, the structural components for performing the functions of such means may include one or more components of UE 120 described in connection with Figure 2 such as antenna 252, DEMOD 254, MOD 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, and so on.

[0057] In some aspects, base station 110 may include various devices or components for implementing communication functions. For example, the various devices may include: a device for receiving information indicating an offset of an energy level of a resynchronization signal (RSS) associated with a neighbor cell relative to a cell-specific reference signal (CRS) of the neighbor cell from a neighbor base station associated with the neighbor cell; a device for transmitting a neighbor cell list including the information indicating the offset; a device for configuring a user equipment (UE) to perform measurements when the offset is within a configured range; a device for determining an offset of an energy level of the resynchronization signal (RSS) of the base station relative to the cell-specific reference signal (CRS) of the base station; a device for transmitting the RSS and the CRS based on the offset; and so on.

[0058] In some aspects, base station 110 may include various structural components for performing the functions of the various devices. For example, the structural components for performing the functions of such devices may include one or more components of base station 110 described in connection with Figure 2 such as transmit processor 220, TX MIMO processor 230, DEMOD 232, MOD 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, and so on.

[0059] As indicated above, Figure 2 is provided merely as an example. Other examples may be different from the examples described with respect to Figure 2 the examples described.

[0060] Figure 3 is a diagram illustrating example 300 of a configuration of an energy level of a resynchronization signal (RSS) for neighbor cell measurements relative to a cell-specific reference signal (CRS) in accordance with various aspects of the present disclosure. As shown, example 300 includes serving BS 110, neighbor BS 110, and UE 120. Serving BS 110 may provide a serving cell for UE 120, and neighbor BS 110 may provide a neighbor cell of the serving cell. In some aspects, serving BS 110 may be associated with multiple neighbor cells provided by one or more neighbor BS 110s. Although the operations described in example 300 are often described with respect to a single neighbor cell and neighbor BS 110, these operations should be understood to apply to multiple neighbor cells and / or neighbor BS 110s. In some aspects, the serving cell and the neighbor cell may be associated with the same frequency, which may be referred to as in-band. In some aspects, the serving cell and the neighbor cell may be associated with different frequencies, which may be referred to as inter-band.

[0061] As Figure 3In the middle and as shown by reference numeral 310, the serving BS 110 may provide a neighbor cell list to the UE 120. In some aspects, the serving BS 110 may use a system information block (SIB) (e.g., SIB2, SIB3, SIB4, SIB5, etc.) to provide the neighbor cell list. The neighbor cell list may identify each neighbor cell for measurement (e.g., RRM measurement and / or etc.). For example, the neighbor cell list may identify each cell identifier associated with these neighbor cells and / or each parameter for measurement on these neighbor cells.

[0062] As shown by reference numeral 320, the neighbor cell list may identify the energy level of the RSS with respect to (e.g., relative to) the CRS. In some aspects, the energy level may be the energy per resource element (EPRE) of the RSS. Here, the neighbor cell list identifies the offset between the energy level of the RSS and the energy level of the CRS (e.g., the respective EPREs of the RSS and the CRS). The identification of the RSS energy level relative to the CRS enables the measurement of the RSS to be consistent with the CRS or enables the measurement of the RSS to be combined with the CRS. In addition, compared to identifying the energy level of the RSS with respect to a baseline or an absolute value, the identification of the RSS energy level relative to the CRS may save resources and reduce overhead. For example, the values of each offset, with reference to Figure 7 .

[0063] In some aspects, the neighbor cell list may identify the offset between the energy level of the RSS and the energy level of the CRS. As an example, the offset may be expressed in decibels (dB). For example, the offset may be in the range of -10 dB to 12 dB. In some aspects, the offset may be quantized into Q bits, where Q is an integer. In some aspects, Q is less than 6. The quantization of the offset may reduce overhead compared to the explicit signaling of the energy level of the RSS or the parameters for determining the energy level of the RSS for certain values of Q.

[0064] In some aspects, the neighbor cell list (e.g., the offset) may identify one or more parameters for determining the energy level of the RSS relative to the CRS. For example, the EPRE of the RSS for a given cell may be determined as follows:

[0065]

[0066] where powerBoost is a configured parameter (∈ {0 dB, 3 dB, 4.8 dB, 6 dB}) referred to herein as the power boost parameter for the RSS, p is the number of CRS ports used by the given cell (∈ {1, 2, 4}), P Brepresents the power boost parameter of the CRS in a given cell, and the parameter and are at least partially determined based on the values of P B and p according to a specified table (e.g., the table specified by 3GPP Technical Specification 36.213). In this case, the neighbor cell list may identify powerBoost, P B and / or p.

[0067] Signaling the above-described parameters explicitly can provide improved accuracy relative to the quantization offset, while the quantization offset can reduce the overhead relative to signaling these parameters explicitly. For example, for powerBoost, P B and p, the signaling values in the above-described example range can use 6 bits per cell (log2(4x3x4)), so if the quantization offset uses less than 6 bits (e.g., Q<6), then the quantization offset can reduce the overhead relative to signaling these parameters explicitly. In some aspects, the quantization can be configured such that the CRS-based measurements and RSS-based measurements are consistent while reducing the signaling overhead.

[0068] The offset associated with RSS can be used to determine the reference signal received power (RSRP) or reference signal received quality (RSRQ) based on RSS. For example, in the case of using CRS-based measurements, UE120 can determine the ranking of the serving cell as Rs and the ranking of the neighbor cell as Rn. Rs can be determined as Qmeas,s + Qhyst – Qoffsettemp, where Qmeas,s is the measurement on the serving cell, Qhyst is the hysteresis value, and Qoffsettemp is the temporary offset value. Rn can be determined as Q meas,n – Qoffset – Qoffset temp , where Qoffset identifies the offset of the energy level of the CRS of the neighbor cell relative to the energy level of the CRS of the serving cell (e.g., for intra-frequency measurements, Qoffset = Qoffset s,n , or for inter-frequency measurements, Qoffset = Qoffset s,n + Qoffset frequency , where Qoffset frequency is the frequency offset value).

[0069] The offset associated with RSS can be an offset relative to the CRS of the neighbor cell, and the CRS of the neighbor cell can be defined by an offset relative to the CRS of the serving cell (e.g., Qoffset as described above). For example, Qoffset_RSS = Qoffsets,n +Delta_offset_RSS s,n , where Delta_offset_RSS s,n is the offset of the CRS of a neighboring cell relative to the RSS. In other words, in some aspects, Delta_offset_RSS s,n is the offset indicated by reference numeral 320. In some aspects, the offset associated with the RSS may be an offset relative to the CRS of the serving cell (e.g., Qoffset_RSS = Qoffset_RSS s,n ).

[0070] As shown by reference numeral 330, the neighboring cell list may optionally indicate an offset range, and RSS-based measurements may be performed at least in part based on the offset range. For example, the UE 120 may be configured not to perform RSS-based measurements when the offset between the RSS and the CRS of a neighboring cell is within a specific range. This range may be associated with a low CRS EPRE (resulting in a high RSS EPRE) or a high CRS EPRE (resulting in a low RSS EPRE). As an example, these ranges may be defined at least in part based on and ratio. In particular, the neighboring cell list may indicate that the UE 120 does not perform measurements when is less than 1 / 2 or greater than 1. As another example, a specific value of the offset may indicate that the UE 120 does not perform RSS-based measurements. For example, if 3-bit quantization is used and the offset is in the range of [-3, 9], the possible values of the offset may include {-3 -1 1 3 5 7 9}, which correspond to seven-bit values. The eighth bit value may indicate that the RSS EPRE is out of range, in which range the RSS will be used for neighboring cell measurements. Thus, the serving BS 110 may implicitly signal the range in which the UE 120 is to perform RSS-based measurements, thereby improving the flexibility of such measurements and reducing the reliance on inaccurate or suboptimal measurements.

[0071] As indicated by reference numeral 340, the neighbor cell list may optionally indicate an offset range, and combined measurements may be performed at least in part based on the offset range (e.g., at least in part based on combining RSS and CRS). For example, in some aspects, UE 120 may perform measurements at least in part based on combining CRS-based measurements and RSS-based measurements. This may be at least in part based on one of the following: the capabilities of UE 120, the presence or absence of RSS in the serving cell and / or neighbor cells, etc. In some aspects, UE 120 may be configured with information indicating an offset range in which UE 120 is to perform combined measurements (e.g., by combining RSS-based measurements and CRS-based measurements). For example, the information indicating the offset range may be provided in the neighbor cell list; provided in a configuration message; specified in a technical specification; etc. By performing combined measurements at least in part based on the range, UE 120 may ensure the accuracy of the combined measurements within the range and may save measurement resources that would otherwise be used to perform inefficient or suboptimal measurements outside the range.

[0072] As indicated by reference numeral 350, neighbor BS 110 may transmit RSS and / or CRS. For example, neighbor BS 110 may transmit RSS according to an RSS EPRE defined by an offset relative to the CRS EPRE, and may transmit CRS according to the CRS EPRE. The CRS EPRE may be defined by an offset relative to the CRS EPRE of serving BS 110. One or more of these offsets may be defined by the neighbor cell list, as described elsewhere herein.

[0073] As indicated by reference numeral 360, UE 120 may perform measurements at least in part based on the energy level of RSS. For example, UE 120 may perform RRM measurements or another type of measurement. In some aspects, UE 120 may perform combined measurements (e.g., at least in part based on the range described above in connection with reference numeral 340). In some aspects, UE 120 may selectively perform measurements. For example, in the case where the offset is within a particular range, or where the quantization of the offset uses a particular value, UE 120 may not perform measurements, as described in more detail in connection with reference numeral 330. Thus, indicating the RSS EPRE to UE 120 relative to the power level of the CRS of neighbor BS 110 reduces the signaling overhead compared to indicating the power level of the CRS relative to serving BS 110 or the RSS EPRE relative to a baseline or global value.

[0074] As indicated above, Figure 3 is provided as an example. Other examples may be different from the example described with respect to Figure 3 above.
