[0028] As used herein, the term "TRP" refers to a network-side transmission / reception point having an antenna array (having one or more antenna elements) located at a specific geographical location and can be used to transmit and receive signals to and from terminal devices. In embodiments of the present disclosure, a TRP may refer to a macrocell, a microcell, an RRH, a relay, a femto node, a pico node, etc. Although some embodiments of the present disclosure are described with reference to two exemplary TRPs, these embodiments are for illustrative purposes and are intended to assist those skilled in the art in understanding and implementing the present disclosure, and do not imply any limitation on the scope of the present disclosure. It should be understood that the present disclosure described herein may be implemented in various manners other than those described below.

[0029] As mentioned above, enabling and / or facilitating dynamic TRP adaptation needs further research. Specifically, a terminal device may need to know whether the TRP(s) configured for it are muted or unmuted, thereby sharing a common understanding with the network to enable dynamic TRP adaptation. However, no such mechanism has been proposed to date.

[0030] According to an embodiment of the present disclosure, a solution for enabling or facilitating dynamic TRP adaptation is provided. In this solution, a first device, i.e., a terminal equipment, receives configuration information for at least one cell or at least one cell group of the first device from a second device, i.e., a network equipment. The configuration information indicates a muting status of at least one TRP of the at least one cell or at least one cell group. Based on the configuration information, the first device determines a muting status of at least one TRP of the at least one cell or at least one cell group. In this way, the terminal equipment can recognize the muting status of the TRP(s) configured in the terminal equipment, so that the terminal equipment can act accordingly to enable dynamic TRP adaptation.

[0031] The principles and embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings, however, it should be noted that these embodiments are shown as exemplary embodiments and are not intended to limit the scope of the present invention in any way.

[0032] Reference is first made to FIG. 1 , which illustrates an exemplary communication system 100 in which embodiments of the present disclosure may be implemented. As shown in FIG. 1 , system 100 includes two network devices, such as network device 111 and network device 112. Network devices 111 and 112 may each have one respective antenna port group. In other words, network devices 111 and 112 may be associated with or function as two respective TRPs, and therefore may also be referred to as TRP 111 and TRP 112 in this disclosure.

[0033] Each of the network devices 111 and 112 may serve one or more areas (also referred to as cells) using different frequency bands in both the DL and UL. In a communication system, "UL" refers to the communication link in the direction from the terminal device to the network device, and "DL" refers to the communication link in the direction from the network device to the terminal device.

[0034] System 100 also includes one or more terminal devices, such as terminal devices 120 and 121. Terminal devices 120 and 121 can connect to and communicate with either or both of network devices 111 and 112 on the UL and DL depending on the location of the terminal devices within the cells of network devices 111 and 112.

[0035] 1, for example, network device 111 may serve cells 101, 102, and 103, and network device 112 may serve cell 102. Cells 101, 102, and 103 may be configured as serving cells for terminal device 120. Cell 102 may be configured as serving cell for terminal device 121.

[0036] Furthermore, although not shown in FIG. 1 , cells 101, 102, and 103 may be grouped into one or more cell groups for terminal equipment 120 according to a grouping rule. For example, cells 101, 102, and 103 may be grouped for the purpose of TRP muting or unmuting. As an example, cells 101, 102, and 103 may be determined as one cell group. As another example, cells 101 and 102 may be determined as a first cell group, and cell 103 may be determined as a second cell group.

[0037] It should be understood that the number of network devices (TRPs) and terminal devices in Figure 1 is for illustrative purposes, without implying any limitation. System 100 may include any suitable number of network devices (TRPs) and terminal devices adapted to implement embodiments of the present disclosure.

[0038] Communications in communication system 100 may be conducted according to any suitable communication protocol(s), including, but not limited to, cellular communication protocols such as first generation (1G), second generation (2G), third generation (3G), fourth generation (4G), and fifth generation (5G), wireless local network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, and / or other protocols now known or developed in the future. Furthermore, communications may utilize any suitable wireless communication technology, including, but not limited to, code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), frequency division duplex (FDD), time division duplex (TDD), multiple input multiple output (MIMO), orthogonal frequency division multiple access (OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM), and / or other technologies now known or developed in the future.

[0039] Reference is now made to Figure 2, which illustrates an example process 200 for enabling dynamic TRP adaptation according to an embodiment of the present disclosure. For purposes of explanation, process 200 will be described with reference to Figure 1.

[0040] A first device 201 and a second device 202 may be involved in the process 200. The first device 201 may be a terminal device, such as terminal device 120 or terminal device 121 as shown in Figure 1. The second device 202 may be a network device, such as network device 111, network device 112 as shown in Figure 1, or other network device that communicates with the first device 201.

[0041] In the process 200, the second device 202 determines configuration information 203 for at least one cell or at least one cell group of the first device 201. The configuration information indicates the muting status of at least one TRP of the at least one cell or at least one cell group of the first device 201.

[0042] The second device 202 may determine whether to mute or unmute the TRP(s) set for the first device 201 for energy conservation, i.e., the second device 202 may determine dynamic TRP adaptation for the first device 201.

[0043] The second device 202 transmits (204) the determined configuration information 210 to the first device 201. The first device 201 receives (205) the configuration information 210 from the second device 202. As an example, the terminal device 120 may receive the configuration information 210 from the network device 111 and / or the network device 112. Based on the configuration information 210, the first device 201 determines (215) the muting state of at least one TRP of at least one cell or at least one cell group.

[0044] In some embodiments, the configuration information 210 may be specific to a cell or a cell group, and the cell or a cell within the cell group may be a serving cell of the first device 201 (or may be a non-serving cell configured with a PCI different from the serving cell PCI). As an example, the terminal device 120 may receive the configuration information 210 indicating the muting status of the TRP 111 of one cell 101. As another example, the terminal device 120 may receive the configuration information 210 indicating the muting status of the TRPs 111 and 112 of a cell group including the cells 101 and 102.

[0045] In some embodiments, configuration information 210 may be specific to multiple cells or multiple cell groups. As an example, terminal device 120 may simultaneously receive configuration information 210 indicating the muting status of TRP 111 in cell 101 and configuration information 210 indicating the muting status of TRPs 111 and 112 in cell 102. As another example, terminal device 120 may receive configuration information 210 indicating the muting status of TRPs in a first cell group that includes cells 101 and 102 and configuration information 210 indicating the muting status of TRP 111 in a second cell group that includes cell 103.

[0046] In some embodiments, the first device 201 may receive 205 the configuration information 210 via a medium access control (MAC) control element (CE). Alternatively or additionally, the first device 201 may receive 205 the configuration information 210 via a radio resource control (RRC) message. Alternatively or additionally, the first device 201 may receive 205 the configuration information 210 via downlink control information (DCI). The DCI may be a user-specific DCI. In other words, the first device 201 may receive 205 the configuration information 201 via a DCI specific to the first device 201. Alternatively, the DCI may be a group-common DCI addressed to a group of devices that make up the first device 201. The group-common DCI may include the configuration information 210.

[0047] FIG. 3 illustrates an example of a group-common DCI 300 including configuration information 210 according to an embodiment of the present disclosure. As illustrated in FIG. 3, the group-common DCI 300 may have a set of bits or fields specific to each group of devices. In other words, each set of bits or fields may be used to indicate configuration information for a respective terminal device. For example, a first set of bits 301-1 may be used to indicate configuration information for terminal device 120, and a second set of bits 301-2 may be used to indicate configuration information for terminal device 121. The group-common DCI 300 may have other sets of bits, such as sets of bits 301-N.

[0048] In some embodiments, the first set of bits 301-1 may be the same as the second set of bits 301-2, and therefore the configuration information indicated by the first set of bits 301-1 may be the same as the configuration information indicated by the second set of bits 301-2. Alternatively, the configuration information indicated by the first set of bits 301-1 may be different from the configuration information indicated by the second set of bits 301-2.

[0049] Returning to FIG. 2 , in some embodiments, the first device 201 may receive 205 the configuration information 210 by receiving a bitmap. The configuration information 210 may be or may be indicated by a bitmap. The value of the bit may indicate the muting state of the TRP, e.g., whether the TRP is muted or unmuted. The number of bits in the bitmap may depend on the number of cells or cell groups configured in the first device 201 for the purpose of enabling dynamic TRP adaptation. Alternatively or additionally, the number of bits may depend on the number of TRP(s) configured in each cell or cell group.

[0050] The bitmap may comprise at least one bit associated with or specific to a cell or group of cells configured for the first device 201 for purposes of enabling dynamic TRP adaptation. For example, the bitmap may include bits 0010 corresponding to cells with two TRPs configured. A first bit value of 1 may indicate that the first TRP is not muted, and a second bit value of 0 may indicate that the second TRP is muted, or vice versa.

[0051] In some embodiments, a primary TRP and a secondary TRP may be configured for a cell. In this case, the bitmap may consist of one bit indicating the muting status of the cell's secondary TRP without any bits indicating the muting status of the cell's primary TRP. In other words, only one TRP may be allowed to be dynamically muted. In this way, the number of bits required to indicate the muting status of TRP(s) can be reduced. For example, if a cell consists of TRP0 and TRP1, and TRP0 is configured as the secondary TRP, the bitmap consists of one bit [0] indicating that TRP0 is muted.

[0052] In some embodiments, the bitmap may include a first bit indicating a muting status of a first TRP of the cell group and a second bit indicating a muting status of a second TRP of the cell group.

[0053] In some embodiments, a first cell and a second cell of a cell group may both be configured with a first TRP and a second TRP, where a first bit value of 1 may indicate that the first TRP is not muted and a second bit value of 0 may indicate that the second TRP is muted for both the first cell and the second cell.

[0054] For example, the bitmap may include bits 0010 corresponding to a cell group including a first cell and a second cell, where a first bit value of 1 may indicate that the first TRP is not muted for the cell group, and a second bit value of 0 may indicate that the second TRP is muted for the cell group.

[0055] In some other embodiments, a first cell of a cell group may be configured with multiple TRPs (e.g., two TRPs with two CORESETPoolIndex configurations) and a second cell of the cell group may be configured with a single TRP (e.g., no multi-TRP configuration is provided for that cell). In this case, a default TRP or TRP identifier may be assumed or configured for the second cell, e.g., a TRP corresponding to a lower or higher index of the TRP identifier (e.g., CORESETPoolIndex 0). Thus, the muting status of the single TRP may be indicated (by default) by a specific bit.

[0056] For example, the bitmap may include bits

[0010] corresponding to a cell group including a first cell and a second cell, where a first bit value of 1 indicates that TRP0 is not muted and a second bit value of 0 indicates that a second TRP1 is muted.

[0057] In some embodiments, the bitmap is made up of sets of bits, each set of bits corresponding to a cell or cell group. For example, the bitmap may include bits [1 0 1 1] corresponding to a first cell / cell group and a second cell / cell group. The first two bits

[0010] correspond to the first cell / cell group, and the second two bits

[0011] correspond to the second cell / cell group.

[0058] In some embodiments, instead of or in addition to a bitmap, the first device 201 may receive 205 the configuration information 210 by receiving an indicator associated with a muting pattern of the at least one muting pattern. The first device 201 may be configured with at least one muting pattern (e.g., via a radio resource control (RRC) configuration), and each muting pattern may indicate a muting state of at least one TRP of a cell or group of cells.

[0059] The indicator may be an index of a muting pattern. Alternatively, the indicator may be a bitmap corresponding to the muting pattern. The indicator may be included in a DCI or MAC CE (or RRC). The first device 201 may receive the indicator via the DCI or MAC CE (or RRC) and apply the muting pattern associated with the indicator to a corresponding cell or cell group.

[0060] In some embodiments, the muting pattern may further indicate a muting period (or muting period) and / or an unmute period (or unmute period). In other words, the muting pattern may indicate a periodic or recurring TRP muting / unmute period. One or more TRPs may be muted during a muting period (or muting period) and unmuted after the muting period (or muting period). Alternatively or additionally, one or more TRPs may be unmuted during an unmute period (or unmute period) and unmuted after the unmute period (or unmute period).

[0061] Furthermore, the muting period and / or unmuting period can be set for one TRP or multiple TRPs. In other words, the muting period can be configured with a set of subperiods for a set of TRPs. For example, the muting period may include a first subperiod and a second subperiod. The first TRP may be muted during the first subperiod, and the second TRP (or both the first and second TRPs) may be muted during the second subperiod.

[0062] In some embodiments, the first device 201 can determine that the configuration information 210 has been received based on a dedicated Radio Network Temporary Identifier (RNTI) that scrambles the DCI. The dedicated RNTI may be a new RNTI or an existing RNTI. The first device 201 may be pre-configured with a set of RNTIs. The dedicated RNTI in the set of RNTIs can indicate that the scrambled DCI includes the configuration information 210.

[0063] Alternatively or additionally, the first device 201 may determine that the configuration information 210 has been received based on at least one dedicated control resource set (CORESET). The at least one dedicated control resource set (CORESET) may be configured or indicated to be used to transmit a physical downlink control channel (PDCCH) carrying DCI including the configuration information 210. Similarly, the first device 201 may pre-configure an association between the at least one dedicated CORESET and the configuration information 210.

[0064] Alternatively or additionally, the first device 201 may determine that the configuration information 210 has been received based on at least one dedicated field or bit in the DCI or MAC CE. The at least one dedicated field or bit may be a newly defined field or an existing field or bit. Similarly, the first device 201 may pre-configure an association between the at least one dedicated field or bit and the configuration information 210.

[0065] Alternatively or additionally, the first device 201 may determine that the configuration information 210 has been received based on a dedicated DCI format. The dedicated DCI format may be an existing DCI format, such as DCI format 0_1 ​​or 0_2 used for scheduling UL transmissions, DCI format 1_1 or 1_2 used for scheduling DL transmissions, or a group-common DCI format such as DCI format 2_6. Alternatively, the dedicated DCI format may be a new DCI format for enabling dynamic TRP adaptation.

[0066] Alternatively or additionally, the first device 201 may determine that it has received the configuration information 210 based on a bitmap indicating the configuration information 210. The first device 201 may receive the bitmap and determine that it has received the configuration information 210.

[0067] In some embodiments, the first device 201 may receive an instruction or configuration from the second device 202 via RRC, MAC CE, or DCI, or hard-coded in a specification. Based on the instruction or configuration, the first device 201 may determine that it has received configuration information 210. As described above, the first device 201 may receive the configuration information 210 via the DCI or MAC CE (or RRC). If it receives the DCI or MAC CE, the first device 201 may determine, based on the instruction or configuration, that the DCI or MAC CE includes the configuration information 210 and determine the muting status of the TRP(s) from the configuration information 210.

[0068] In some embodiments, the instruction or configuration may be a dedicated Radio Network Temporary Identifier (RNTI) that scrambles the DCI. The dedicated RNTI may be a new RNTI or an existing RNTI. The first device 201 may be pre-configured with a set of RNTIs. The dedicated RNTI in the set of RNTIs may indicate that the scrambled DCI includes the configuration information 210.

[0069] Alternatively or additionally, the indication or configuration may be a dedicated DCI format. The dedicated DCI format may be an existing DCI format, for example, DCI format 0_1 ​​or 0_2 used for scheduling UL transmissions, DCI format 1_1 or 1_2 used for scheduling DL transmissions, or a group-wide DCI format such as DCI format 2_6. Alternatively, the dedicated DCI format may be a new DCI format for the purpose of enabling dynamic TRP adaptation.

[0070] Alternatively or additionally, the instructions or settings may be part of a bitmap indicating the configuration information 210. The first device 201 can receive the bitmap and determine that the configuration information 210 has been received. In other words, the bitmap indicates that the configuration information 210 is being conveyed and may also indicate the configuration information 210 itself.

[0071] It should be noted that in some embodiments, the configuration information 210 indicating the muting state of the TRP(s) may be implemented by reusing indicators of the bandwidth part (BWP) dormancy information and / or wake-up information of the first device 201. For example, DCI format 2_6 or an existing bitmap currently used to indicate wake-up information and / or BWP dormancy information may be reused as or to indicate the configuration information 210.

[0072] Additionally, in some embodiments, cells may be grouped for purposes of enabling dynamic TRP adaptation based on grouping rules for purposes of BWP dormancy. In other words, configuration information 210 may be specific to a cell group that is the same as a cell group configured for BWP dormancy or cell dormancy.

[0073] In some embodiments, the configuration information 210 may indicate both the muting status of the TRP(s) and the BWP dormant information (or wake-up information). For example, a bit in a bitmap may indicate both the muting status of the TRP(s) and the dormant status of the BWP. As another example, an existing bitmap for BWP dormant information may be expanded in size to accommodate the bits required to indicate the muting status of the TRP(s).

[0074] In this case, upon receiving the DCI or MAC CE, the first device 201 may first determine, based on an instruction or configuration, whether the DCI or MAC CE includes configuration information 210 indicating one of a muting state, BWP pause information, or wake-up information. The first device 201 may further determine the muting state of the TRP(s) from the configuration information 210 based on a pre-configured association between the configuration information 210 and the first device's interpretation of the configuration information 210.

[0075] Alternatively, upon receiving a DCI or a MAC CE, the first device 201 may determine, based on an instruction or configuration, that the DCI or MAC CE includes configuration information 210, and may also determine, based on the instruction or configuration, the muting state of the TRP(s) from the configuration information 210. For example, the first device 201 may determine, based on a dedicated RNTI, that the scrambled DCI includes configuration information 210 and determine the muting state of the TRP(s).

[0076] Based on the configuration information 210, the first device 201 determines a muting state 215 of at least one TRP of at least one cell or at least one cell group of the first device 201.

[0077] In some embodiments, the first device 201 may determine a mute state for a TRP (e.g., each TRP) of the at least one TRP as one of a set of states. The set of states may include a first state in which all transmissions and receptions between the first device 201 and the TRP are muted. The first state may also be referred to as a full mute state.

[0078] Alternatively or additionally, the set of states may include a second state in which at least one predetermined transmission or reception between the first device 201 and the TRP is muted. The predetermined transmission(s) or reception(s) muted in the second state may be defined in a specification. Alternatively, the predetermined transmission(s) or reception(s) muted may be provided to the first device 201 via an RRC configuration. The second state may also be referred to as a partial mute state. The partial mute state may be considered a type of TRP dormant state.

[0079] For example, if a TRP is in a partially muted state, the first device 201 may not expect a PDCCH to be transmitted from the TRP. In this case, the first device 201 may not monitor the PDCCH. As another example, the first device 201 may not expect to receive from this TRP.

[0080] Alternatively or additionally, the set of states may define a third state in which transmission and reception between the first device and the TRP is not muted. In other words, the first device 201 can expect normal transmission and reception with the TRP. The third state may also be referred to as an unmuted state.

[0081] In some embodiments, the first device 201 may be configured or instructed (e.g., via RRC or MAC CE) whether to consider a full muting state or a partial muting state when determining the muting state. Alternatively, the first device 201 may be instructed via DCI or MAC CE using new or existing field(s), bit(s), or format(s) whether to consider a full muting state or a partial muting state.

[0082] In some embodiments, the predetermined transmission / reception period in the second state may be different from the corresponding predetermined transmission / reception period in the third state. The predetermined transmission / reception may be a transmission / reception that is unmuted in the partial mute state, but the transmission / reception period may be longer than the period in the unmuted state. Therefore, better energy conservation can be achieved.

[0083] In some embodiments, the first device 201 may determine, for a TRP of the at least one TRP, a muting state for the BWP of the cell in which the TRP is configured. In other words, the muting state may be configured at the BWP level, rather than for the entire bandwidth of the cell.

[0084] In some embodiments, a TRP may be identified by a CORESETPoolIndex. Alternatively or additionally, a TRP may be identified by its ID, e.g., a TRP ID. Alternatively or additionally, a TRP may be identified by a set of Reference Signals (RS). Alternatively or additionally, a TRP may be identified by a set of RS resources. Alternatively or additionally, a TRP may be identified by a Physical Cell ID (PCI).

[0085] In this way, through the process 200, the muting status of the TRP(s) set in the first device 201, for example, the terminal equipment 120, can be indicated to the first device 201. Thus, the first device 201 can operate according to the muting status of the TRP(s), thereby enabling dynamic TRP adaptation.

[0086] 4 illustrates another example of a process 400 for enabling dynamic TRP adaptation according to an exemplary embodiment of the present disclosure. Note that process 400 can be considered a more specific example of process 200. It will be understood that process 400 can be applied to communication system 100 of FIG. 1 and any other similar communication scenarios.

[0087] 4, the first device 201 may receive 405 a first configuration 410 including a set of RNTIs. Each RNTI may be used to indicate whether the scrambled DCI includes one or more of the following information: a muting status of TRP(s), BWP dormancy information, or wake-up information (or other information). For example, a first RNTI may indicate that the corresponding DCI includes information about the muting status of TRP(s), a second RNTI may indicate that the corresponding DCI includes information about BWP dormancy information, and a third RNTI may indicate that the corresponding DCI includes information about both the muting status of TRP(s) and BWP dormancy information.

[0088] The first device 201 may further receive a second setting 420 for configuring cell groups for the purpose of enabling dynamic TRP adaptation. The second setting 420 may indicate configuring a first cell group (also referred to as cell group 0) and a second cell group (also referred to as cell group 1) for the first device 201.

[0089] The first device 201 may receive 425 the DCI 430 scrambled with an RNTI (e.g., the first RNTI or the third RNTI) used to indicate that the DCI 430 contains muting status information for the TRP(s). The DCI 430 may include a bitmap, such as [1 0 0 0].

[0090] The first device 201 may determine 435 that the DCI 430 includes information on the muting status of the TRP(s) based on the RNTI that scrambles the DCI 430. The first device 201 may further determine 440 the muting status of the TRP(s) in the first cell group and the second cell group based on the bitmap included in the DCI 430.

[0091] As an example, based on the bitmap [1 0 0 0], the first device 201 may determine 440 that the first two bits

[0010] correspond to cell group 0, the second two bits

[0000] correspond to cell group 1, a bit value of 0 indicates muting the TRP, and a bit value of 1 indicates unmuting the TRP. The first device 201 may determine 440 that a first TRP (e.g., TRP 0) may be unmuted for cell group 0 and muted for cell group 1, and may determine 440 that a second TRP (e.g., TRP 1) may be muted for both cell group 0 and cell group 1.

[0092] Similarly, the first device 201 may receive 445 a DCI 450 scrambled with an RNTI (e.g., the first RNTI or the third RNTI) used to indicate that the DCI 450 contains muting status information for the TRP(s). The DCI 450 may include a bitmap [1 1 1 1].

[0093] The first device 201 may determine 455 that the DCI 450 includes information on the muting status of the TRP(s) based on the RNTI that scrambles the DCI 450. The first device 201 may further determine 460 the muting status of the TRPs in the first cell group and the second cell group based on the bitmap included in the DCI 450.

[0094] As an example, based on the bitmap [1 1 1 1], the first device 201 may determine that the first two bits

[0011] correspond to cell group 0, the second two bits

[0011] correspond to cell group 1, a bit value of 1 indicates unmuting the TRP, and a bit value of 0 indicates muting the TRP (460). The first device 201 may determine that TRP0 may be unmuted for cell group 0 and may be unmuted for cell group 1 (460).

[0095] 4, if TRP0 is configured for cell group 1 but not for cell group 0, first device 201 may determine, based on bitmap [1 1 1 1], that TRP0 may be unmuted for cell group 1. Also, first device 201 may determine that TRP1 may be unmuted for both cell group 0 and cell group 1.
