Description

[0001] Title

[0002] Improved control information provision

[0003] Field

[0004] Various example embodiments relate to improved control information provision. More specifically, various example embodiments exemplarily relate to measures (including methods, apparatuses, and computer program products) for realizing improved control information provision.

[0005] Background

[0006] The present specification generally relates to transmission of information, or, more general, to provision of information.

[0007] The information may be control information. More specifically, the information may be uplink control information.

[0008] Such uplink control information may include, for example, layer-1 (LI) uplink control information (UCI) and medium access control (MAC) control elements (CE).

[0009] Examples for MAC CEs include a channel state information (CSI) MAC CE, a hybrid automatic repeat request (HAR.Q) acknowledgment (ACK) MAC CE, a buffer status report (BSR.) MAC CE, or a beam failure recovery (BFR.) MAC CE, and any other MAC CE. Examples for Ll-UCI include a CSI and a HAR.Q-ACK.

[0010] While the present disclosure and the underlying problem is described mainly using CSI MAC CE as an example, the concept of the present disclosure is applicable as well in general to MAC CEs and Ll-UCI, and in particular to those given as examples above. CSI MAC CEs are related to the CSI measurement and reporting framework.

[0011] The CSI measurement and reporting framework utilizes CSI reference signals (RS).

[0012] CSI-RSs are user equipment (UE) specifically configured in radio resource control (RRC).

[0013] However, CSI-RS reference signals can be shared among many UEs, i.e., more than one UE are configured to receive the same resource elements (RE).

[0014] In general, in order to save on downlink (DL) resources, a 3rdGeneration Partnership Project (3GPP) New Radio (NR) base station (gNB) would try to use cell-specific or group-specific CSI-RS resources.

[0015] The worst case of DL overhead is with UE specific CSI-RS, where the DL overhead increases linearly with the number of UEs in the cell.

[0016] CSI-RS has many functions in NR, e.g. :

[0017] - CSI-RS for DL CSI acquisition,

[0018] - CSI-RS for beam management (BM) (based on Ll-RSRP),

[0019] - CSI-RS for tracking (total radiated sensitivity (TRS)),

[0020] - UL CSI acquisition in reciprocity-based UL precoding.

[0021] In some applications (e.g., CSI-RS for BM), CSI-RSs are spatially beamformed into different directions.

[0022] In general, a UE can be configured with up to 48 report configurations (CSI- ReportConfig) per component carrier (CC) and 4 report configurations per bandwidth part (BWP).

[0023] One CSI-ReportConfig within one report configuration can be configured with up to 16 resource sets (aperiodic CSI) and one resource set (otherwise). In each CSI resource set, up to 64 non-zero power (NZP) CSI-RS resources and one NZP CSI-RS resource up to 32 antenna ports can be configured.

[0024] For CSI acquisition, the UE is configured also with a codebook type. Given the measured channel across a CSI-RS resource, the UE can choose a favorite codeword from the specified codebook, i.e., precoding matrix indicator (PMI), along with a channel quality indicator (CQI) and a rank indicator (RI). The UE can also be configured to measure several CSI-RS resources (up to 8) within a resource set and report the favorite resource, and a CSI-RS resource indicator (CRI), along with PMI, CQI and RI, which correspond to that selected resource.

[0025] In the time domain (within a slot), a CSI-RS resource may start at any orthogonal frequency division multiplexing (OFDM) symbol of a slot and it spans 1, 2, or 4 OFDM symbols depending on the number of ports configured.

[0026] The UE measurement reporting of CSI can be operated in a periodic, semi- persistent, or aperiodic manner (report types in NR report configuration).

[0027] However, there are certain limitations, based on which the UE periodic report can operate only based on the configured periodic CSI-RS resource set, the UE semi-persistent report can operate based on both configured periodic and semi-persistent CSI-RS resource set, and finally the UE aperiodic report can operate based on all periodic, semi-persistent, and aperiodic CSI-RS resource set.

[0028] In other words, the periodic CSI-RS resources can be used to generate any report type, the semi-persistent CSI-RS resources can be used to generate semi-persistent and aperiodic CSI reports, and the aperiodic CSI-RS resources can only be utilized only to generate the aperiodic report. With respect to frequency granularity, the CSI report setting also defines which part of the bandwidth the CSI should correspond to, and in addition, what granularity in frequency the CSI should have.

[0029] To accomplish this, the bandwidth of a BWP is divided into a number of subbands for CSI reporting.

[0030] All CSI-RS resources within one set are configured with same density and same number of antenna port (nrofPorts), except for the NZP CSI-RS resources used for interference measurement.

[0031] For semi-persistent and aperiodic CSI-RS, the actual triggering of CSI-RS transmission is per CSI-RS resource set via either MAC CE or downlink control information (DCI). A resource set can be used as part of UE report configurations describing what to be measured, and, correspondingly, which measurement reporting is / are to be done by the UE.

[0032] Specifically, if a CSI-RS resource set is configured as 'aperiodic' by RRC, the CSI-RS resource set configuration includes a slot offset, aperiodicTriggeringOffset, which defines the time interval between the triggering DCI and the CSI-RS transmission.

[0033] For A-CSI reporting (aperiodic CSI reporting), up to 16 different reporting settings can be triggered with a single DCI (e.g. for multiple component carriers), while SP-CSI reporting (semi-persistent CSI reporting) can trigger only one report setting with a single DCI.

[0034] In order to trigger several SP-CSI reports (each in different slots), multiple DCIs are needed.

[0035] P-CSI reporting (periodic CSI reporting) is configured with a physical uplink control channel (PUCCH) resource for transmission, but if the PUCCH is overlapping in time with a physical uplink shared channel (PUSCH), periodic CSI can be transmitted on the PUSCH, and the PUCCH is dropped. SP-CSI can be transmitted on PUCCH, when triggered by MAC CE, or on PUSCH, when triggered by DCI. A-CSI is transmitted on PUSCH.

[0036] CSI report content is outlined below.

[0037] For Type I and Type II CSI feedback on PUSCH, a CSI report comprises of two parts. Part 1 has a fixed payload size and is used to identify the number of information bits in Part 2. Part 1 shall be transmitted in its entirety before Part 2.

[0038] For Type I CSI feedback, Part 1 contains R.I (rank indicator, if reported), CRI (CS-R.S resource indicator, if reported), CQI (channel quality indicator), for the first codeword. Part 2 contains PMI (precoding matrix indicator, if reported), LI (layer indicator, if reported), and contains the CQI for the second codeword when R.I (if reported) is larger than 4.

[0039] For Type II CSI feedback, Part 1 contains R.I (if reported), CQI, and an indication of the number of non-zero wideband amplitude coefficients per layer for the Type II CSI. The fields of Part 1 - R.I (if reported), CQI, and the indication of the number of non-zero wideband amplitude coefficients for each layer - are separately encoded. Part 2 contains the PMI of the Type II CSI. Part 1 and 2 are separately encoded.

[0040] Precoder matrices W in Type-I and R.el-15 Type-II codebooks can be described as being decomposed into two matrix factors which are each matrix factor such that W(ii, iz) = Wi(ii) W2G2), where Wi is precoder matrix targeting the long-term channel which is selected on a wide-band basis, while W2 targets the short-term / frequency-selective properties of the channel and can be reported on a per-subband basis. For future releases (be it for 5thGeneration (5G) or 6thGeneration (6G)), some CSI content / reporting may be pushed to MAC layer in form of MAC element(s) (such as MAC CE(s)).

[0041] With CSI reporting operation handled at MAC layer, implying a CSI MAC element such as CSI MAC CE, an important aspect is the reliability of the CSI MAC CE.

[0042] Namely, such (CSI) MAC CE would be multiplexed with data and jointly encoded with data. Hence, considering legacy operations, to achieve better reliability for the MAC CE, e.g., the modulation and coding scheme (MCS) of a respective transport block (TB) (including logical channel (LCH) data and MAC CE) would need to be decreased. This would, however, negatively affect the uplink (UL) throughput. On the other hand, when maintaining the UL throughput, potentially resulting in a maintained or even increased MCS, this may avoid a desired / necessary reliability for the MAC CE.

[0043] Hence, the problem arises that control information transfer might lead to disadvantageous tradeoff between at least the reliability of the control information and data throughput. More generally, there is a need to enable detaching control information from data.

[0044] Hence, there is a need to provide for improved control information provision.

[0045] Various example embodiments aim at addressing at least part of the above issues and / or problems and drawbacks.

[0066] Detailed description

[0067] The present disclosure is described herein with reference to particular nonlimiting examples and to what are presently considered to be conceivable embodiments. A person skilled in the art will appreciate that the disclosure is by no means limited to these examples, and may be more broadly applied.

[0068] It is to be noted that the following description of the present disclosure and its embodiments mainly refers to specifications being used as non-limiting examples for certain exemplary network configurations and deployments. Namely, the present disclosure and its embodiments are mainly described in relation to 3GPP specifications being used as non-limiting examples for certain exemplary network configurations and deployments. As such, the description of example embodiments given herein specifically refers to terminology which is directly related thereto. Such terminology is only used in the context of the presented non-limiting examples, and does naturally not limit the disclosure in any way. Rather, any other communication or communication related system deployment, etc. may also be utilized as long as compliant with the features described herein.

[0069] In addition, as already mentioned above, while the present disclosure and the underlying problem is described mainly using CSI MAC CE as an example, the concept of the present disclosure is applicable as well in general to MAC CEs (e.g. CSI MAC CE, HARQ ACK MAC CE, BSR MAC CE, BFR MAC CE, and any other MAC CE), or MAC control elements in general, and Ll-UCI (e.g. CSI, HARQ-ACK, SR (scheduling request)).

[0070] Hereinafter, various embodiments and implementations of the present disclosure and its aspects or embodiments are described using several variants and / or alternatives. It is generally noted that, according to certain needs and constraints, all of the described variants and / or alternatives may be provided alone or in any conceivable combination (also including combinations of individual features of the various variants and / or alternatives).

[0071] As used herein, "at least one of the following: " and "at least one of " and similar wording, where the list of two or more elements are joined by "and" or "or", mean at least any one of the elements, or at least any two or more of the elements, or at least all the elements.

[0072] According to example embodiments, in general terms, there are provided measures and mechanisms for (enabling / realizing) improved control information provision.

[0073] As mentioned above, with CSI reporting operation handled at MAC layer, implying a CSI MAC element such as CSI MAC CE, an important aspect is the reliability of the CSI MAC CE. Namely, wherein multiplexing and encoding such CSI MAC CE with data, considering legacy operations, to achieve better reliability for the MAC CE, e.g., the modulation and coding scheme (MCS) of a respective transport block (TB) (including logical channel (LCH) data and MAC CE) would need to be decreased. This would, however, negatively affect the uplink (UL) throughput. On the other hand, when maintaining the UL throughput, potentially resulting in a maintained or even increased MCS, this may avoid a desired / necessary reliability for the MAC CE.

[0074] Be it for CSI MAC CE or any MAC CE / information that would have a different (i.e., higher) reliability than data, it would be advantageous to detach the MAC CE / information reliability from the data reliability as much as possible without necessarily having to separately encode / modulate such control information and data. Hence, in brief, according to example embodiments, mapping of uplink control information (uplink control information element(s)), e.g., MAC CE(s) (such as CSI MAC CE, HAR.Q-ACK MAC CE) or Ll-UCI (such as CSI, HAR.Q- ACK) to a dedicated codeblock (CB) or a dedicated codeblock group (CBG) is enabled. This enables better reliability of the uplink control information, such as MAC CE or Ll-UCI, e.g. through repetition of the uplink control information itself or the dedicated CB or the dedicated CBG and / or retransmission of the dedicated CBG.

[0075] Multiplexing packets from different data radio bearers into one TB increases the spectral efficiency. Using CBGs helps in increasing resource efficiency on retransmissions.

[0076] If a UE is configured to receive CBG-based transmissions when the R.R.C parameter codeBlockGroupTransmission is set, the UE determines the number of CBGs for a PUSCH transmission.

[0077] The UL uses the same asynchronous HAR.Q protocol as the DL.

[0078] Necessary HARQ-related information including process number, new-data indicator, and code block group transmission information (CBGTI; when configured) are included in the scheduling grant. CBG-based retransmissions are transparent to the MAC sublayer and are handled in the physical layer despite being part of the HAR.Q mechanism.

[0079] From the MAC perspective, the TB is not correctly received until all CBGs are correctly received and decoded.

[0080] While the present disclosure is described mainly using CB and CBG as dedicated logical entities to which control information is mapped, the concept of the present disclosure is applicable as well in general to other dedicated logical entities or elements as well. Examples for other dedicated logical entities or elements to which control information is mapped according to example embodiments include Ll-elements, elements, code elements, uplink control information (UCI) elements, or control information elements, etc. Uplink control information may for example also be mapped to a dedicated transport block (TB) (for example in case of allowed / standardized multiple TBs).

[0081] Example embodiments are specified below in more detail.

[0134] More general, according to example embodiments, the UE obtains information for mapping at least one uplink control information, Ll-UCI / MAC control element, to a transport block(s).

[0135] In step S72 of FIG. 7, according to example embodiments, the UE determines to transmit a transport block including a MAC CE.

[0136] In step S73 of FIG. 7, according to example embodiments, the UE maps the (at least one) MAC CE to at least one dedicated CB or CBG of the transport block(s) based on the (obtained / received) information / configuration.

[0137] In step S74 of FIG. 7, according to example embodiments, the UE transmits a PUSCH carrying the transport block(s) which include(s) the MAC CE mapped to the at least one dedicated CB or CBG.

[0138] FIG. 5 is a schematic diagram of illustrating an exemplary control information alternative according to example embodiments.

[0139] As is illustrated in FIG. 5, a CSI MAC CE may be mapped to a dedicated CB (CB#0). The dedicated CB (CB#0) may be included in a dedicated CBG (CBG#0).

[0140] According to example embodiments, mapping a MAC CE (or MAC element) to one or multiple CB(s) or CBG(s) may depend at least on:

[0141] - the channel coding type used for PUSCH carrying MAC CE, e.g. LDPC or polar codes,

[0142] - parameters of channel coding, e.g. LDPC based Graph MAC CE size, e.g., larger MAC CE size may require more segmentation. According to example embodiments, a MAC control element (or MAC element) is a CSI MAC CE. Alternatively, or additionally, the MAC CE may be a HAR.Q- ACK MAC CE, or BSR MAC CE, or BFR MAC CE, or any other MAC CE or MAC element.

[0143] According to example embodiments, the UE is configured / indicated, e.g., via RRC or MAC CE or DCI (or even broadcast / multicast signaling, such as SIB1), and / or even at least partially specified (e.g., based on specifications), which at least one CB or CBG is dedicated for mapping the at least one MAC control element. For example, the mapping is into first CB(s) or first CBG(s). The indication may additionally include information regarding or on whether segmentation of MAC CE to one or multiple CBs or CBGs is set.

[0145] According to example embodiments, the UE is configured or indicated, e.g., via RRC or MAC CE or DCI, whether or not to map LCH data into the dedicated at least one CB or at least one CBG for the at least one MAC CE.

[0146] According to example embodiments, dedicated interleaving for CBs associated to MAC CE is applied on top of PUSCH interleaving. The interleaving can be applied at bit level or at CB level, e.g., interleaving CBs associated to MAC CE over PUSCH.

[0147] According to example embodiments, the UE is configured / indicated with a configured size or a size limit / cap for the dedicated at least one CB or at least one CBG.

[0148] According to example embodiments, the UE is configured with a least one rule or condition for mapping the at least one MAC element to the at least one dedicated CB or CBG. For instance, mapping the at least one MAC element to at least one dedicated CB or CBG may be applicable if one or more of the following is satisfied:

[0149] - the size of the transport block is above or below a certain threshold,

[0150] - the size of the at least one MAC element is above or below a certain threshold,

[0151] - or LCH data size is above or below a certain threshold.

[0152] According to example embodiments, mapping to at least one dedicated CB or CBG is applicable depending on the MAC element type or priority.

[0153] According to example embodiments, mapping to at least one dedicated CB or CBG is applicable depending on the available UL resources, such as UL-SCH resources or PUSCH resources, etc.

[0154] According to example embodiments, mapping to at least one dedicated CB or CBG is applicable depending on the number and / or size of CBs or CBGs for the transport block(s).

[0156] According to example embodiments, the UE is configured to not split a CSI report to multiple CBs / CBGs. The last one may avoid retransmission of multiple CBGs to decode one CSI report.

[0157] According to example embodiments, there is a dedicated (at least one) CB or CBG for a CSI report or for a set / subset of CSI reports. CSI report configuration or triggering state may comprise or be associated with information indicative of the mapping of one or multiple CSI reports to a dedicated at least one CB or CBG. According to example embodiments, a part of the HAR.Q-ACK information is mapped to a dedicated at least one CB or CBG, and another part of the HAR.Q- ACK information is mapped to another dedicated at least one CB or CBG. For example, HAR.Q-ACK corresponding to some configured or indicated set / subset of cells / CCs, PUSCH occasions, and / or HAR.Q processes, may be associated / mapped to (at least) one dedicated CB or CBG. Such correspondence is included by both the above-mentioned control information scope (first control information scope, second control information scope), and the above-mentioned control information association (first control information association, second control information association). Namely, such correspondence includes that the HAR.Q-ACK is associated with the configured or indicated set / subset of cells / CCs / carriers / BWPs, PUSCH occasions, and / or HAR.Q processes. Further, such correspondence also includes that the HAR.Q-ACK is valid in the realm / domain / scope of the configured or indicated set / subset of cells / CCs / carriers / BWPs, PUSCH occasions, and / or HAR.Q processes.

[0158] According to example embodiments, the at least one dedicated CB or CBG are mapped / associated, through indication or configuration, to a specific (e.g., physical or logical) channel element. Examples of (e.g., physical or logical) channel element include:

[0169] - CBs or CBGs where the at least one MAC element is to be repeated,

[0170] - a repetition factor for the at least one MAC element,

[0171] - PUSCH occasions, or PUSCH configurations, where MAC element can be repeated. According to example embodiments, the UE is configured or indicated or specified not to map LCH data into the dedicated CBs or CBGs for the repetition of the at least one MAC control element.

[0172] According to example embodiments, the UE is configured or indicated, e.g., via R.R.C or MAC CE or DCI, whether or not to map LCH data into the dedicated CBs or CBGs for the repetition of the at least one MAC CE.

[0173] According to example embodiments, the repetition of (UL) MAC CE can be applied e.g., intra-slot as well as inter-slot.

[0174] According to example embodiments, mapping a MAC CE (or MAC element) to one or multiple CB(s) or CBG(s) may depend at least on :

[0175] - the channel coding type used for PUSCH carrying MAC CE, e.g. LDPC or polar codes,

[0176] - parameters of channel coding, e.g. LDPC based Graph MAC CE size, e.g., larger MAC CE size may require more segmentation.

[0177] According to example embodiments, a MAC control element (or MAC element) is a CSI MAC CE. Alternatively, or additionally, the MAC CE may be a HAR.Q- ACK MAC CE, or BSR MAC CE, or BFR MAC CE, or any other MAC CE or MAC element.

[0178] According to example embodiments, the UE is configured / indicated, e.g., via RRC or MAC CE or DCI, or even specified, which at least one CB or CBG is dedicated for mapping the at least one MAC control element.

According to example embodiments, the UE is configured or indicated, e.g., via R.R.C or MAC CE or DCI, whether or not to map LCH data into the dedicated at least one CB or at least one CBG for the at least one MAC CE.

[0180] According to example embodiments, dedicated interleaving for CBs associated to MAC CE is applied on top of PUSCH interleaving. The interleaving can be applied at bit level or at CB level, e.g., interleaving CBs associated to MAC CE over PUSCH.

[0184] - the size of the transport block is above or below a certain threshold,

[0185] - the size of the at least one MAC element is above or below a certain threshold,

[0186] - or LCH data size is above or below a certain threshold.

[0187] According to example embodiments, mapping to at least one dedicated CB or CBG is applicable depending on the MAC element type or priority.

[0188] According to example embodiments, mapping to at least one dedicated CB or CBG is applicable depending on the available UL resources, such as UL-SCH resources or PUSCH resources, etc. According to example embodiments, mapping to at least one dedicated CB or CBG is applicable depending on the number and / or size of CBs or CBGs for the transport block(s).

[0189] According to example embodiments, the at least one dedicated CB or CBG may be considered separately, meaning that at least one dedicated CB or CBG may not be considered or assumed as part of the transport block(s) (e.g., from counting of number of CBs or CBGs perspective, or from segmentation perspective, or from overall handling perspective).

[0190] According to example embodiments, the UE indicates if there is at least one CB or CBG into which the at least one MAC element is mapped.

[0191] According to example embodiments, the UE is configured to not split a CSI report to multiple CBs / CBGs. The last one may avoid retransmission of multiple CBGs to decode one CSI report.

[0192] According to example embodiments, there is a dedicated (at least one) CB or CBG for a CSI report or for a set / subset of CSI reports. CSI report configuration or triggering state may comprise or be associated with information indicative of the mapping of one or multiple CSI reports to a dedicated at least one CB or CBG.

[0193] According to example embodiments, a part of the HAR.Q-ACK information is mapped to a dedicated at least one CB or CBG, and another part of the HAR.Q- ACK information is mapped to another dedicated at least one CB or CBG.
