The above is to establish a relationship between an uplink PUCCH resource group or SRS resource group and a TCI state or TCI code point, and similarly, may also establish a relationship between a downlink control channel resource group and a TCI state or TCI code point, where a quasi-co-located reference signal of the downlink control channel resource group is obtained according to a quasi-co-located reference signal of the TCI state or TCI code point having a corresponding relationship with the quasi-co-located reference signal. The MAC-CE updates the TCI state or TCI code point, and then the quasi-co-located reference signal of the downlink control channel resource group is updated. Wherein the downlink control channel resource group comprises one of the following: a downlink control channel resource group in a frequency domain bandwidth, a downlink control channel resource group composed of downlink control channel resources in different frequency domain bandwidths in a frequency domain bandwidth group and having the same downlink control channel resource index, wherein the downlink control channel resources include one of: and searching a space set by a downlink control resource set CORESET.

Similarly, a relationship between an uplink data channel PUSCH group and a TCI state or a TCI code point may also be established, for example, in the PUSCH configuration information configured by the higher layer, the corresponding TCI state or TCI code point is configured.

Example embodiment three

Corresponding relations exist between P1 PUCCH resource groups in the P PUCCH resource groups and CORESET, and parameters of PUCCH resources in the PUCCH resource groups are obtained according to quasi co-located reference signals of CORESET having corresponding relations with the PUCCH resource groups, or according to reference signals in TCI state of CORESET, as shown in the first exemplary embodiment.

Corresponding relations exist between P2 PUCCH resource groups in the P PUCCH resource groups and the TCI state, and parameters of PUCCH resources in the PUCCH resource groups are obtained according to reference signals in the TCI state having corresponding relations with the PUCCH resource groups, as shown in example embodiment two. Wherein P1, P2 is a positive integer less than or equal to P, or P1+ P2 ═ P.

Similarly, the S1 SRS resource groups in the S SRS resource groups have a corresponding relationship with CORESET, and the S2 SRS resource groups have a corresponding relationship with TCI state.

Through the scheme, the corresponding relation between the uplink channel or signal group and the downlink channel or signal is established, when the parameters of the downlink channel or signal change, the parameters of the uplink channel or signal corresponding to the parameters change, when the parameters of the downlink channel or signal are updated by the signaling information, the parameters of the uplink channel or signal are also updated together, and the parameters of the uplink channel or signal in the uplink channel or signal group change, so that the purpose of quickly tracking the change of the beam while saving the signaling overhead is realized, for example, the change of the parameters implicitly reflects the change of the beam.

In the above scheme, the parameter of the uplink channel or signal is obtained according to the quasi-co-located reference signal of the downlink channel or signal corresponding to the parameter, and the reference signal in the TCI state of the downlink channel or signal corresponding to the parameter. At this time, if the parameters of the uplink channel or signal are updated through the signaling information or the predetermined rule, the quasi-co-located reference signal of the downlink channel or signal corresponding to the parameters is also updated, so that the beam change or other parameter changes can be quickly tracked while signaling is saved.

Example embodiment four

In this embodiment, the parameters of the uplink channel or signal are obtained according to the quasi-co-located reference signal of the downlink channel or signal, the uplink channel or signal occupies a plurality of time units, and the quasi-co-located reference signal of the downlink channel or signal is updated in a range of the plurality of time units occupied by the uplink channel or signal, that is, two pieces of quasi-co-located reference signal information corresponding to the downlink channel or signal in the plurality of time units occupied by the uplink channel or signal, the quasi-co-located reference signal information before updating, and the updated quasi-co-located reference signal information need to select one of the two pieces of quasi-co-located reference signal information according to control information or a predetermined rule or determine the quasi-co-located reference signal corresponding to each time unit. As shown in fig. 6, the parameter of the uplink channel or signal is obtained according to the quasi co-located reference signal of the CORESET having the lowest CORESET index in the serving cell corresponding to the uplink channel or signal, for example, according to the quasi co-located reference signal of the CORESET0, while the quasi co-located reference signal of the CORESET0 is updated by the MAC-CE, for example, the terminal receives the PDSCH including the MAC-CE in slot (n-8), the original TCI state of the CORESET0 is TCI state1, the MAC-CE updates the TCI state of the CORESET0 to TCI state2, the TCI state updated by the MAC-CE is available in slot (n +5), the uplink channel or signal (such as the PUCCH resource in fig. 6) is transmitted in slot (n) -slot (n +7, the TCI state of the CORESET0 before slot (n +5) is the TCI state1, the TCI state of the CORESET is updated in slot (n +5), and the TCI state of the CORESET 3968 is updated in slot (n + 5). That is, in the time domain range occupied by the uplink channel or signal of the PUCCH, the CORESET0 has two TCI states, and it needs to be determined that the parameter of the PUCCH is obtained according to TCI state1 or TCI state2, for example, the spatial transmission filter that obtains the uplink channel or signal according to the quasi co-located reference signal in TCI state1 is transmission beam 1, the spatial transmission filter that obtains the uplink channel or signal according to the quasi co-located reference signal in TCI state2 is transmission beam 2, and at this time, it needs to be determined that the transmission beam of the uplink channel or signal is transmission beam 1 or transmission beam 2. Specifically, one or more of the following schemes may be employed.

Scheme 1: determining parameters of an uplink channel or signal according to a TCI state activated by a downlink channel or signal in a first time unit (for example, a first slot) in which the uplink channel or signal is located, and obtaining parameters of the uplink channel or signal in each time unit (i.e., the second time unit) of the plurality of time units, where the parameters of the uplink channel or signal are the same, as shown in fig. 7.

Scheme 2: determining parameters of an uplink channel or signal according to a TCI state activated by a downlink channel or signal in a time unit (i.e., the first time unit) in which the uplink channel or signal is located, and acquiring parameters of the uplink channel or signal in each of the plurality of time units (i.e., the second time unit), as shown in fig. 8, the TCI state before updating is adopted before the time unit before the MAC-CE starts to be available, and the TCI state after updating is adopted in the time unit when the MAC-CE starts to be available.

Scheme 3: according to the time unit of the uplink channel or signal, the downlink channel or signal is activated and can be used for determining the parameter of the uplink channel or signal by the TCI state, and after the TCI state of the downlink channel or signal is updated, the TCI state can be used for obtaining the parameter of the uplink channel or signal after X time domain symbols or Y time units. In scheme 2, X is 0 and Y is 0, and in scheme 3, X and Y are positive integers greater than or equal to 1. Wherein X and Y are used for the terminal to obtain the downlink receiving beam, and the minimum time required for the terminal to obtain the uplink sending beam according to the downlink receiving beam and send the uplink channel or signal by adopting the uplink sending beam In one embodiment, the terminal may report the X or Y value as the terminal capability to the base station. For example, X belongs to {14,28,42} and Y belongs to {1,2,3 }. As shown in fig. 9 to 10, X is 14, Y is 1 in fig. 9, X is 28, and Y is 2 in fig. 10. If the quasi co-located reference information of the downlink channel or signal is updated by the MAC-CE, the quasi co-located reference signal information of the downlink channel or signal included in the MAC-CE is

The subsequent Y +1 slot may be used for acquiring the uplink channel or signal parameter.

Scheme 4: determining whether to adopt a scheme 1 or a scheme 2 according to the proportion of the number of the first-class time units and the number of the second-class time units, wherein the first-class time units correspond to time units of uplink channels or signals before the update of the quasi-co-located reference signal information of the downlink channels or signals, the second-class time units correspond to time units of the uplink channels or signals after the update of the quasi-co-located reference signals of the downlink channels or signals (including the time units where the update is located), when the proportion is smaller than or equal to 1, adopting the scheme 2, and when the proportion is larger than 1, adopting the scheme 1, or when the proportion is smaller than or equal to 1, adopting the scheme 1 before the uplink channels or signals

(or before)

) In the time unit of (2), the parameter of the uplink channel or signal is obtained according to the TCI state before updating, and in the remaining time unit of the uplink channel or signal, the parameter of the uplink channel or signal is obtained according to the TCI state after updating, where N is the number of time units occupied by the uplink channel or signal. I.e. when the updating of the downlink channel or signal takes place in

(or

) In the case of time units before slot, scheme 2, or pre-slot, may be employed

(or before)

) The time unit (2) before the update is used, and the rest of the time units after the update are used, as shown in fig. 11. When the update of the downlink channel or signal occurs

(or

) In the case of time units after slot, scheme 1 is employed. If the quasi co-located reference information of the downlink channel or signal is updated by the MAC-CE, the quasi co-located reference signal information of the downlink channel or signal included in the MAC-CE is

The first slot thereafter is available (for example, at this time, the quasi-co-located reference signal of the downlink channel or signal may be updated to the quasi-co-located reference signal in the TCI state carried in the MAC-CE), where slot (k) is the slot where the terminal feeds back the ACK for the PDSCH including the MAC-CE,

Is the number of slots included in a subframe, and the subcarrier spacing of PUCCH is 15kHz 2^μThat is, the first type of time unit comprises a plurality of time units occupied by the uplink channel or signal before a predetermined time unit, wherein the predetermined time unit comprises

The first slot thereafter, e.g. slot (n +5) in fig. 6), the second type of time cell comprises time cells both of which are predetermined time and after predetermined time cells.

In scheme 5, the parameters of the PUCCH are determined according to the quasi co-located reference signal of CORESET0 in the time unit nearest to the first time unit and including CORESET 0. As shown in fig. 12, although the updated TCI state of CORESET0 is available in slot (n +4), there is no search space to be detected associated with CORESET0 on slot (n +4), slot (n) is a distance slot (n +4) and the slot including CORESET0 is slot (n) before slot (n +4), and the available TCIstate of CORESET0 in slot (n) is the TCI state before update, so starting from slot (n +6), the PUCCH acquires parameters based on the updated TCIstate of CORESET 0.

Similarly, the predetermined time unit (i.e., the third time unit) is defined as

And the first slot + Y time units later can determine whether to adopt the scheme 1 or the scheme 3 according to the ratio of the number of the first type time units to the number of the second type time units, and only the scheme 2 in the scheme 4 is replaced by the scheme 3.

In one embodiment, the uplink channel includes at least one of: PUCCH, PUSCH, uplink signals including SRS.

In one embodiment, the parameters of the uplink channel or signal include at least one of: the channel estimation method comprises a spatial sending filter, a spatial relation reference signal, a power parameter, a transmission mode and an associated CSI-RS.

In an embodiment, the power parameter includes a path loss reference signal of the uplink channel or signal.

In an embodiment, the parameter of the uplink channel or signal is obtained according to a quasi co-located reference signal of an associated predetermined quasi co-located parameter of the downlink channel or signal, for example, the predetermined quasi co-located parameter includes a spatial receiving parameter.

In fig. 6 to 12, the number of TCI states of before-update and after-update CORESET0 is 1, and in an embodiment, the number of TCI states of before-update and after-update CORESET0 is 2, as shown in fig. 13 to 15, at this time, PUCCH resources are repeatedly transmitted in 8 slots, 2 TCI states of CORESET0 are replaced every 2 slots, but as shown in fig. 13 to 15, the update signaling of MAC-CE is validated at slot (n +5), slot (n +5) belongs to the slot group of 2 slots, which is next to the slot group, and at this time, if the above scheme 2 is adopted, one of the processes in fig. 13 to 15 can be adopted. In fig. 13, the updated TCI state starts to acquire parameters for PUCCH resources from the first slot after the available slot, that is, the quasi co-located reference signal information of CORESET0 adopted by switching the parameters of PUCCH only in the first slot of the group of slots, and in fig. 14, if all 3 slots in the second class of time unit use the updated first TCI state, TCI state 2. In fig. 15, the updated TCI state starts parameter acquisition for PUCCH resources at an available slot, and the TCI state of the next slot group is switched. In fig. 16, 2 TCI states are before update, and 1 TCI state is after update. Or 8 slots (i.e. the N time units) are divided into a plurality of groups, for example, 2 slots are used as one group, the parameters of the PUCCH are obtained according to the quasi co-located reference signal of the CORESET0 available in the first time unit in each group, or the parameters of the PUCCH resource are switched between the new and old quasi co-located reference signal information of the CORESET0 only in the first time unit of the group of time units, and are not switched in other time units, for example, the updated quasi co-located reference signal of the CORESET0 is available in the non-first time unit of the group of time units, then the group of time units all use the quasi co-located reference signal before updating of the CORESET0, the updated quasi co-located reference signal of the CORESET0 is available in the first time unit of the group of time units, then the group of time units further define the value of at most corresponding to 0 (i.e. 2 parts of the quasi co-located reference signal) in the N time units with the updated quasi co-located reference signal of the CORESET0, that is, in N time units, the core et0, in the above embodiment, one time unit is a slot, but this embodiment does not exclude that one time unit is one of the following: sub-time units sub-slots, subframes, etc.

In fig. 6, quasi co-located reference signals of downlink channels or signals are updated by MAC-CE, another way of this embodiment is to determine the quasi co-located reference signals of the downlink channels or signals by a predetermined rule, for example, when the quasi co-located reference signals of CORESET0 are obtained according to the PRACH that is recently sent by the terminal, the downlink reference signals corresponding to the PRACH are obtained, or there is a correspondence between the quasi co-located reference signals of CORESET0 and the downlink synchronization signals. Or the quasi-co-located reference signal of the downlink channel or signal is updated through the PDCCH, and the quasi-co-located reference signal of the downlink channel or signal updated by the PDCCH is available in one of the multiple time units occupied by the uplink channel or signal.

The above schemes 1 to 4 are examples of obtaining parameters of an uplink channel or signal according to a quasi co-located reference signal of coreset (control resource set), and similarly, the above schemes are also suitable for a scenario where the parameters of the uplink channel or signal are obtained according to TCIstate, where TCI state may be the TCI state described in the second exemplary embodiment. The situation of fig. 6 also occurs when the MAC-CE updates the TCI state of the PDSCH.

Or the scheme is also suitable for a scene that the MAC-CE directly updates the parameters of the uplink channel or signal. Specifically, for example, the spatial relationship information of the PUCCH is updated by the MAC-CE, the PUCCH is repeatedly transmitted in 8 slots, and the MAC-CE starts to be available in one slot of the 8 slots occupied by the PUCCH (that is, 3ms after the ACK for the PDSCH including the MAC-CE falls in one slot of the 8 slots), that is, in the range of the 8 slots occupied by the PUCCH, the spatial relationship of the PUCCH corresponds to two available configurations, and it is necessary to determine which configuration needs to be adopted by the PUCCH. Particularly, one or two of the two configurations includes more than 2 spatial relationship information, where the more than 2 (including 2) spatial relationships respectively correspond to different resources of the PUCCH, where the resources include one of the following: frequency domain resources, time domain resources and demodulation reference signal resources, wherein each piece of spatial relationship information comprises a reference signal and a transmission beam of the PUCCH.

Similarly, the above schemes 1 to 4 are also applicable to a scenario that a channel or a signal occupies a plurality of time units, and a parameter of the channel or the signal is updated in one of the time units, for example, the base station updates the parameter through a MAC-CE, information in the MAC-CE is available in one of the time units, and it is required to determine whether the parameter of the channel or the signal is updated in each of the time units.

Specifically, for example, the MAC-CE updates the parameters of the PUSCH, and the information indicated in the MAC-CE starts to be available in one of the time units occupied by the PUSCH. Any of the above schemes 1 to 4 may be adopted to determine whether the parameters of the PUSCH in each time unit of the PUSCH are before update or after update. Or when the uplink channel is the PUSCH, adopting scheme 1, and when the PUCCH, adopting scheme 2, because the PUSCH has an MCS, it may not be appropriate for the TCIstate before update and the TCI state after update to adopt the same MCS, but the PUCCH does not have an MCS, and therefore adopting scheme 2 or scheme 3.

Or the MAC-CE updates the TCI state of the downlink control channel resource, and the information indicated in the MAC-CE starts to be available in one of the time units occupied by the downlink control channel resource. Any of the above schemes 1 to 5 may be adopted to determine whether the path loss reference signal of the PUSCH is before update or after update in each time unit of the PDCCH. Wherein the downlink control channel resource comprises one of: CORESET, search space, candidate control channel.

In one embodiment, the time unit includes one of: sub-slot, subframe, etc., the time unit for which the MAC-CE starts to be available, for example, C time units are available after the terminal sends an ACK for the PDSCH including the MAC-CE, and what the time units are here is what the above time units are.

Example embodiment five

As shown in fig. 17, in updating the spatial relationship reference signal of the aperiodic sounding reference signal (AP-SRS) resource by MAC-CE command, there is an S-domain in the MAC-CE, which indicates whether the serving cell and BWP where the spatial relationship reference signal of different AP-SRS resource in AP-SRSset is located are shared. When the S domain indicates sharing, the serving cell and the BWP where the spatial relationship reference signals of different AP-SRS resources in the AP-SRS set are located are shared, and the content included in the MAC-CE is as shown in fig. 18, that is, when the spatial relationship reference signals of different AP-SRS resources in the AP-SRS resource set are located in the same serving cell and BWP and are not shared, as shown in fig. 17. Further, the S and C domains may be jointly encoded, and C is frequency domain bandwidth information indicating whether the MAC-CE includes a spatial relationship reference signal.

Example embodiment six

The base station allocates more than one SRS resource set to the terminal, wherein the SRS resource set is used as non-codebook, SRSresource terminals in different SRS resource sets in the more than one SRS resource set cannot simultaneously transmit, and the SRS resource belonging to the same SRS resource set can simultaneously transmit at most G, wherein G is the terminal capability.

In an embodiment, the time domain characteristics of the more than one non-codebook SRS resource sets are the same, wherein the time domain characteristics include one of: aperiodic, periodic, and semi-persistent.

In an embodiment, the port numbers of srsrsresources in the more than one non-codebook SRS resource sets are obtained according to the SRS resource set index where the SRS resource is located and the relative index of the SRS resource set where the SRS resource is located. For example, the port number of the ith SRS resource in the jth non-codebook SRS resource set is: 1000+ i + j F, where F is a predetermined value, such as the maximum number of SRS resources included in a non-codebook SRSresource set, such as 4, or the port number of the ith SRS resource in the jth non-codebook SRS resource is

Wherein F_lIs the number of SRS resources in the l non-coded SRS resource set.

In an embodiment, the associatedCSI-RSs in the more than one non-codebook SRS resource set are associated with the same downlink reference signal.

In an embodiment, the more than one non-codebook SRS resource sets are located in a frequency domain bandwidth, such as a serving cell, or a BWP. That is, in a plurality of non codebook SRS resource sets associated with the same associatedce csi-RS, SRS resource sets belonging to different non codebook SRS resource sets cannot be transmitted simultaneously, and SRS resource sets belonging to different non codebook SRS resource sets can be transmitted simultaneously.

According to the embodiment of the invention, the corresponding relation is established for the uplink target element group and the downlink channel element, and after the quasi co-location reference signal of the downlink channel element is updated, the spatial transmission filter of the uplink target element in the uplink target element group is changed, so that the purpose of rapidly following the beam is achieved while the signaling overhead is saved.

One channel or signal occupies a plurality of time units, the parameter corresponding to the channel or signal in one time unit of the plurality of time units is updated, and it needs to be determined whether the parameter of the channel or signal in each time unit of the channel or signal is determined according to the parameter before or after updating.
