Patent Description:
<NPL>) is directed to the view of companies on remaining issues for UL data transmission without UL grant, especially for resource configuration, UE identification, physical channel structure and related procedures. <CIT> relates to wireless communication, and more specifically to a downlink control information (DCI) design for multilayer transmission,.

Embodiments and aspects that do not fall within the scope of the claims are merely examples used for explanation of the invention.

UEs <NUM> (e.g., 120a, 120b, 120c, 120d, 120e) may be dispersed throughout wireless network <NUM>, and each UE may be stationary or mobile.

At base station <NUM>, a transmit processor <NUM> may receive data from a data source <NUM> for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs.

Controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, and/or any other component(s) of <FIG> may perform one or more techniques associated with transmit parameter control, as described in more detail elsewhere herein. For example, controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, and/or any other component(s) of <FIG> may perform or direct operations of, for example, process <NUM> of <FIG>, process <NUM> of <FIG>, and/or other processes as described herein. Memories <NUM> and <NUM> may store data and program codes for base station <NUM> and UE <NUM>, respectively.

In some aspects, UE <NUM> may include means for receiving, from a base station (BS), a group-common downlink control information (DCI) message transmitted to a plurality of user equipment (UEs), wherein the group-common DCI message includes information identifying at least one communication parameter for the UE, means for communicating with the BS in accordance with the at least one communication parameter based at least in part on receiving the group-common DCI message transmitted to the plurality of UEs, and/or the like. In some aspects, such means may include one or more components of UE <NUM> described in connection with <FIG>.

In some aspects, base station <NUM> may include means for transmitting a group-common downlink control information (DCI) message to a plurality of user equipment (UEs), wherein the group-common DCI message includes information identifying at least one communication parameter, means for communicating with at least one of the plurality of UEs in accordance with the at least one communication parameter based at least in part on transmitting the group-common DCI message to the plurality of UEs and/or the like. In some aspects, such means may include one or more components of base station <NUM> described in connection with <FIG>.

Each subframe may have a predetermined duration (e.g., <NUM>) and may include a set of slots (e.g., <NUM>m slots per subframe are shown in <FIG>, where m is a numerology used for a transmission, such as <NUM>, <NUM>,<NUM>, <NUM>, <NUM>, and/or the like). In some aspects, a scheduling unit for the FDD may frame-based, subframe-based, slot-based, symbol-based, and/or the like.

Each resource block may cover a set to of subcarriers (e.g., <NUM> subcarriers) in one slot and may include a number of resource elements.

An interlace structure may be used for each of the downlink and uplink for FDD in certain telecommunications systems (e.g., NR). For example, Q interlaces with indices of <NUM> through Q - <NUM> may be defined, where Q may be equal to <NUM>, <NUM>, <NUM>, <NUM>, or some other value. Each interlace may include slots that are spaced apart by Q frames. In particular, interlace q may include slots q, q + Q, q + 2Q, etc., where q ∈ {<NUM>,. , Q - <NUM>}.

New Radio (NR) may refer to radios configured to operate according to a new air interface (e.g., other than Orthogonal Frequency Divisional Multiple Access (OFDMA)-based air interfaces) or fixed transport layer (e.g., other than Internet Protocol (IP)). In aspects, NR may, for example, utilize OFDM with a CP (herein referred to as CP-OFDM) and/or discrete Fourier transform spread orthogonal frequency-division multiplexing (DFT-s-OFDM) on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using time division duplexing (TDD). NR may include Enhanced Mobile Broadband (eMBB) service targeting wide bandwidth (e.g., <NUM> megahertz (MHz) and beyond), millimeter wave (mmW) targeting high carrier frequency (e.g., <NUM> gigahertz (GHz)), massive MTC (mMTC) targeting non-backward compatible MTC techniques, and/or mission critical targeting ultra-reliable low latency communications (URLLC) service.

NR resource blocks may span <NUM> sub-carriers with a sub-carrier bandwidth of <NUM> or <NUM> kilohertz (kHz) over a <NUM> duration.

In some communications systems, such as <NUM> or NR, a BS may signal communication parameters to a UE to enable communication with the UE. However, for some types of communications, the BS may lack signaling to signal the communication parameters efficiently and in a timely manner. For example, when the BS is to receive a PUSCH transmission in connection with providing a radio resource control (RRC) configured grant, the BS may be configured to use RRC signaling to indicate an adjustment to a communication parameter for the PUSCH transmission, which may result in an excessive delay to indicate the adjustment. Similarly, when the UE is to transmit a PUSCH transmission in connection with a downlink control information (DCI) activation transmission or when the BS is to transmit a downlink semi-persistent scheduling (DL SPS) transmission, the BS may be configured to use the DCI activation message to signal an adjustment to a communication parameter for each UE of a plurality of UEs. In this case, signaling separate adjustments to each UE for which the BS is to adjust communication parameters may result in excessive utilization of network resources, excessive use of BS resources, and/or the like.

Some aspects described herein may enable signaling of a group-common DCI message to signal communication parameters for a plurality of UEs. For example, the BS may determine a change to at least one communication parameter, and may transmit the group-common DCI message to a plurality of UEs to indicate the change to the at least one communication parameter. In this case, the BS may communicate with at least one of the plurality of UEs, such as by transmitting a DL SPS transmission, receiving a PUSCH transmission, and/or the like. In this way, based at least in part on transmitting the group-common DCI message dynamically, the BS may reduce a delay in adjusting a communication parameter relative to using RRC signaling, and may reduce a utilization of network resources and BS resources relative to transmitting a plurality of UE-specific activation DCIs. Furthermore, based at least in part on signaling a change to a communication parameter rather than an absolute value for a communication parameter, the BS may reduce a utilization of network resources to transmit the group-common DCI message.

<FIG> and <FIG> are diagrams illustrating examples <NUM> of transmit parameter control, in accordance with various aspects of the present disclosure. As shown in <FIG> and <FIG>, example <NUM> includes a BS <NUM> and a plurality of UEs <NUM> (e.g., a first UE <NUM>, a second UE <NUM>, a third UE <NUM>, and/or the like).

As further shown in <FIG>, and by reference number <NUM>, BS <NUM> may determine one or more communication parameters. For example, BS <NUM> may determine that a current communication parameter value is to be changed relative to a previously signaled at least one communication parameter value. In this case, the BS <NUM> may have previously signaled a plurality of communication parameters using a configured grant (e.g., the configured grant may be signaled using radio resource control (RRC) signaling or is activated using an activation DCI), and may determine that the at least one communication parameter is to be changed from a previously signaled value to another value. In some aspects, BS <NUM> may determine a plurality of UEs <NUM> for which the one or more communication parameters are to be applied. For example, BS <NUM> may determine that, of a plurality of UEs <NUM> that are communicating with BS <NUM>, a particular subset of the plurality of UEs <NUM> are to have a current communication parameter value changed to a different communication parameter value.

In some aspects, BS <NUM> may determine a particular type of communication parameter value, such as a modulation and coding scheme (MCS) parameter. Additionally, or alternatively, BS <NUM> may determine a resource allocation type of communication parameter, such as a starting resource block for a communication, a quantity of resource blocks allocated for the communication, a frequency hopping position for the communication, a starting orthogonal frequency division multiplexing (OFDM) symbol for the communication, a quantity of OFDM symbols to use for the communication, and/or the like. Additionally, or alternatively, BS <NUM> may determine a precoder type of communication parameter, such as which precoder to use for precoding. Additionally, or alternatively, BS <NUM> may determine a repetition parameter type of communication parameter, such as a quantity of repetitions of the communication to transmit, a slot bundling value for the communication, a mini-slot bundling value for the communication, and/or the like.

As further shown in <FIG>, and by reference number <NUM>, BS <NUM> may transmit, and one or more UEs <NUM> may receive, a group-common DCI message identifying one or more communication parameters. For example, BS <NUM> may transmit the group-common DCI message to a plurality of UEs <NUM>, such as a first UE <NUM>, a second UE <NUM>, a third UE <NUM>, and/or the like, to adjust a communication parameter of the first UE <NUM>, the second UE <NUM>, the third UE <NUM>, and/or the like. In this case, the group-common DCI message may include information for the plurality of UEs <NUM> (e.g., setting a communication parameter in common for the plurality of UEs <NUM>) and/or UE-specific information (e.g., identifying a particular communication parameter for first UE <NUM>, another particular communication parameter for second UE <NUM>, and/or the like).

In some aspects, BS <NUM> may indicate a change to the communication parameter. For example, BS <NUM> may provide, using the group-common DCI message, an indicator that the communication parameter is to change from a first value to a second value, without providing information explicitly signaling the first value or the second value. In other words, BS <NUM> may provide a bit indicator indicating that a starting resource block is to be increased by a delta value to a new starting resource block, rather than signaling an absolute value of the new starting resource block. As another example, BS <NUM> may provide a bit indicator indicating that an MCS is to be increased by a delta value to a new MCS (e.g., based on an ordered set of MCSs), rather than signaling the MCS explicitly. In this way, BS <NUM> may decrease a size of the DCI message relative to signaling the absolute value, thereby reducing a utilization of network resources.

In some aspects, BS <NUM> may transmit information identifying an accumulative delta value. In this case, BS <NUM> may transmit an indicator identifying a change to the communication parameter value relative to a sequentially last value for the communication parameter. In some aspects, BS <NUM> may transmit information identifying an absolute delta value. In this case, BS <NUM> may transmit an indicator identifying a change to the communication parameter value relative to a sequentially first communication parameter value (e.g., an initial communication parameter value that may be configured based at least in part on an RRC configuration message or a DCI activation message).

In some aspects, BS <NUM> may signal an absolute value for a communication parameter. For example, when a size of an indicator to signal an absolute value for the communication parameter is less than a threshold, thereby obviating a reduction in a message size from using a delta value as an indicator, BS <NUM> may include an indicator of the absolute value in the group-common DCI message. In some aspects, BS <NUM> may implicitly signal a communication parameter value using the group-common DCI message. For example, BS <NUM> may include an indicator of an MCS, based at least in part on which UE <NUM> may derive an allocated quantity of resource blocks (e.g., without BS <NUM> explicitly signaling the allocated quantity of resource blocks), thereby reducing a size of the group-common DCI message and reducing a utilization of network resources.

In some aspects, BS <NUM> may include an indicator of when a change to a communication parameter is to become effective. For example, BS <NUM> may include a k0 indicator identifying a quantity of slots between reception of a downlink group-common DCI message and when a communication parameter value change is to become effective. Similarly, BS <NUM> may include a k2 indicator identifying a quantity of slots between reception of an uplink group-common DCI message and when a communication parameter value change is to become effective. In this case, UE <NUM> may apply the communication parameter value change and communicate in accordance with the communication parameter value change after the time at which the communication parameter value change is to become effective. Additionally, or alternatively, UE <NUM> may communicate using an original communication parameter before applying the communication parameter value change based at least in part on the indicator of when the change to the communication parameter is to become effective. In some aspects, the time is a UE-specific time indicated by a field of the group-common DCI message (e.g., each of the plurality of UEs is associated with a corresponding time field) that indicates when the parameter value change is to become effective. In some aspects, the time is non-UE-specific (e.g., the time is a group-common time field applicable to each UE of the plurality of UEs).

In some aspects, UE <NUM> may apply the communication parameter value change based at least in part on a timing of receiving the group-common DCI message. For example, UE <NUM> may determine to apply the communication parameter value change based at least in part on receiving the group-common DCI message a threshold quantity of symbols before a PUSCH transmission is scheduled. In contrast, if the group-common DCI message is not received the threshold quantity of symbols before the PUSCH transmission is scheduled, UE <NUM> may determine to apply a same communication parameter as was used for a previous transmission using a same configured grant as for the transmission of the PUSCH. This may occur as a result of insufficient processing time at the UE to apply the communication parameter value change between the reception of the DCI and the transmission of the PUSCH. In this case, UE <NUM> may apply the communication parameter indicated by the group-common DCI message after a PUSCH transmission and for another PUSCH transmission.

In some aspects, UE <NUM> may monitor for the group-common DCI message based at least in part on a monitoring parameter. For example, before BS <NUM> transmits and UE <NUM> receives the group-common DCI message, BS <NUM> may transmit RRC signaling to UE <NUM> to configure one or more monitoring parameters for UE <NUM>, such as a radio network temporary identifier (RNTI), a size of the group-common DCI message, a resource location of control information for UE <NUM>, and/or the like. In some aspects, UE <NUM> may monitor for different group-common DCI messages. For example, UE <NUM> may monitor for a first type of group-common DCI message (e.g., a downlink group-common DCI message) for a DL SPS transmission with a first size or a first RNTI, and may monitor for a second type of group-common DCI message (e.g., an uplink group-common DCI message) for a PUSCH transmission with a configured grant with a second size or a second RNTI. Additionally, or alternatively, the first type of group-common DCI message and the second type of group-common DCI message may be associated with a common size (e.g., based at least in part on adding padding bits) and a common RNTI. In this case, UE <NUM> may determine whether a received group-common DCI message is the first type (e.g., a DL group-common DCI for a DL SPS) or the second type (e.g., a UL group-common DCI for a PUSCH with a configured grant) based at least in part on a bit indicator included in the received group-common DCI message.

In some aspects, UE <NUM> may determine that the group-common DCI message is a group-common DCI message and not a re-activation DCI. For example, UE <NUM> may parse the group-common DCI message to determine that the group-common DCI message is a group-common DCI message based at least in part on an RNTI of the group-common DCI message, a DCI format of the group-common DCI message, a bit indicator included in the group-common DCI message, and/or the like.

In some aspects, UE <NUM> may determine a bandwidth part switching command included in the group-common DCI message. For example, UE <NUM> may process the group-common DCI message to identify a UE-specific bandwidth part switch indicator, a bandwidth part switch indicator for, and common to, the plurality of UEs <NUM>, and/or the like. Additionally, or alternatively, UE <NUM> may identify a starting resource block, a quantity of resource blocks, a frequency hopping offset, and/or the like for an active bandwidth part, a previous bandwidth part, and/or the like. In this case, a reference point for applying a communication parameter change may be reception of the group-common DCI message by UE <NUM>, a completion of a bandwidth part switch, the later one of the reception and the completion, and/or the like. Further, a change to a communication parameter value may be relative to a communication parameter value for a bandwidth part to which UE <NUM> switches.

As further shown in <FIG>, and by reference number <NUM>, BS <NUM> and UE <NUM> may communicate in accordance with the one or more communication parameters. For example, BS <NUM> may transmit a DL SPS transmission to UE <NUM> in accordance with the one or more communication parameters, and UE <NUM> may receive the DL SPS transmission. Additionally, or alternatively, UE <NUM> may transmit a PUSCH transmission in accordance with the one or more communication parameters, and BS <NUM> may receive the PUSCH transmission. In this case, the one or more communication parameters may be applied to the DL SPS transmission and/or the PUSCH transmission, and may not be applied to other transmissions, such as dynamically scheduled uplink transmissions or downlink transmissions.

In some aspects, BS <NUM> may communicate with the plurality of UEs <NUM> in accordance with the one or more communication parameters. For example, based at least in part on setting the one or more communication parameters using the group-common DCI message, BS <NUM> may transmit to and/or receive from the plurality of UEs <NUM>, thereby reducing a delay in setting a communication parameter and/or reducing a utilization of network resources to set a communication parameter.

As shown in <FIG>, and by reference number <NUM>, in a similar scenario, BS <NUM> may transmit a configured grant to UE <NUM>. For example, BS <NUM> may transmit the configured grant, which may identify a sequence of communication opportunities between the BS <NUM> and the UE120, and may identify a plurality of communication parameters relating to the sequence of communication opportunities. For example, the configured grant may correspond to a downlink semi-persistent scheduling transmission. In this case, one or more of the plurality of communication parameters may be transmitted from the BS <NUM> to the UE <NUM> via the activation DCI of the downlink semi-persistent scheduling transmission. In another example, the configured grant may correspond to a sequence of physical uplink shared channel transmissions, which do not need to be activated. In this case, the plurality of communication parameters may be included in the configured grant configuration. As shown by reference number <NUM>, at a subsequent time, BS <NUM> may determine that one or more communication parameters are to be changes. For example, BS <NUM> may determine that a value for a communication parameter, of the plurality of communication parameters indicated in the configured grant, is to be changed to a different value.

As further shown in <FIG>, and by reference number <NUM>, BS <NUM> may transmit a group-common DCI message identifying the one or more communication parameters. For example, BS <NUM> may indicate a change to a value of at least one communication parameter of the plurality of communication parameters using a group-common DCI message transmitted to UE <NUM>. In this case, the group-common DCI message may include a UE specific region (UE1) that may include one or more fields to update one or more communication parameters. For example, a first field (CP1) may indicate an update to a first communication parameter indicated in the configured grant, a second field (CP2) may indicate an update to a second communication parameter indicated in the configured grant, a third field (CP3) may indicate an update to a third communication parameter indicated in the configured grant, and/or the like. As shown by reference number <NUM>, based at least in part on the update to the one or more communication parameters, BS <NUM> and UE <NUM> may communicate (e.g., using a PUSCH transmission) in accordance with the one or more communication parameters.

However, the protection scope of this application shall be subject to the protection scope of the claims.

Claim 1:
A method (<NUM>) of wireless communication performed by a base station, BS, comprising:
transmitting (<NUM>) a group-common downlink control information, DCI, message to a plurality of user equipment, UEs, wherein the group-common DCI message includes information identifying a time at which at least one communication parameter for uplink or downlink transmission becomes effective; and
communicating (<NUM>) with at least one of the plurality of UEs using a different communication parameter than the at least one communication parameter after transmitting the group-common DCI message and before the at least one communication parameter becomes effective.
